CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a Continuation-In-Part of National Stage Application (U.S. application Ser. No. 14/126,287 filed 13 Dec. 2013) of International Application PCT/US2012/049007 having an international filing date of 31 Jul. 2012 which was a continuation of U.S. patent application Ser. No. 13/217,997, filed 25 Aug. 2011 (now U.S. Pat. No. 8,251,221), the entireties of the contents thereof expressly incorporated by reference thereto for all purposes. 
    
    
     BACKGROUND OF THE INVENTION 
     This embodiment pertains to the general field of glass-lined enclosures and more particularly, but not exclusively, to a recyclable, reusable protective housing, which seals and protects an open-ended tubular member such as a glass vial or jar and the like. 
     The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also be inventions. 
     One of the most effective means of storing and transporting substances is the use of glass-lined containers. Recently, though, plastic has become the preferred material for many products that, in the past, were exclusively manufactured from glass, such as medicine vials, jars and bottles. The reasons for the replacement of glass by plastic are primarily that plastic weighs less and is less expensive and is easier to produce. Along with additional safety factors, such as less chance of breakage, it is no surprise that plastic has almost completely replaced glass containers. 
     The main industries that continue to rely upon glass for containers are the medical and natural remedy industries. While plastic jars have replaced glass jars and bottles in some applications, there is still a need for glass. This is particularly true for the storage and transport of certain medicines and natural remedies, extracts, oils and tinctures, such as those that are susceptible to contamination or may leach into plastic containers. 
     A major problem exists in that plastic containers have been shown to cause contamination of the contents therein. An increasingly large population of people now prefer glass containers due to concerns over the risk of leaching from bisphenol A and phthalates, two additives used in plastic containers. Plastic containers also allow certain, usually organic compounds, medications to be absorbed into the plastic surface of the container itself, which may reduce potency of medications stored therein. Such contamination of a plastic containers also prevents the possibility of reuse or recycling of the container. 
     The only solution to many of these problems has been to continue storing and transporting medications and natural remedies in glass containers. Unfortunately, a glass container is considered undesirable due to the risk that it may break. 
     If there were some way to continue using glass containers for medications and natural remedies, with all of the safety characteristics of plastic, for the above reasons glass-based containers would be preferred in many situations. Such a glass container would offer the benefits of modern plastic containers such as an airtight seal, without risk of over or under-tightening; easy opening even for the elderly and disabled; with essentially effortless, resealing; and the container would be entirely re-usable and recyclable and free from the risk of chemical leaching. Such a container would also be shockproof to reduce the risk of breakage, while being aesthetically pleasing as well as simple and reliable yet inexpensive to fabricate.

     The U.S. Pat. No. 5,695,090 discloses a removable insulating container, which grips a bottle such that the container is held snugly in place. The container uses a separate lower sleeve and an upper cap, which are mounted on a medicine bottle to substantially encase the medicine bottle. The container is fabricated from a multi-layer flexible material, which has an impact resistant outer layer and an inner layer, which forms an internal channel that grips the side of the medicine bottle. The proximal end of the lower sleeve extends past the bottom of the bottle to prevent it from impacting a surface should it be dropped. 
     The U.S. Pat. No. 1,063,351 relates to protective casings or enclosures for bottles and similar receptacles of glass or other fragile material and has for its main object the construction of a casing in such a way as to make a bottle contained therein immune from breakage if the casing is allowed to fall. Another object of the invention is the construction of a casing, which is both simple and inexpensive to manufacture. A further object of the invention is the construction of a casing in which is formed grooves or pockets, which may be used for the carrying of any desired articles such as thermometers etc. 
     The U.S. Pat. No. 6,793,076 discloses a glass bottle protective housing designed to protect a glass bottle in the event the bottle is subjected to an impact shock. The enclosure is provided with a leak-proof seal and is particularly adapted for protecting glass bottles containing toxic injectable medication. The enclosure, which is preferably made from a transparent plastic, consists of a lower bottle container which includes a base and a plurality of shock absorbers, which are located to allow a bottle label to be clearly visible, on the base is located at least one sensor cavity into which is inserted an enclosure leakage sensor consisting of either a water soluble sensor or an electronic sensor. Both of which provide an indication if a bottle leakage occurs. To complete the enclosure the container includes a threaded bottle container cap, which includes a plurality of cap shock absorbers. 
     The U.S. Pat. No. 5,699,922 discloses a container closure system including a plurality of equally circumferentially distributed pins extending outwardly from a tubular neck of the container near the opening. A detachable cap consisting of nested inner and outer cap members. The inner cap member is dimensioned to receive the container neck and includes a plurality of sidewall openings for receiving the pings. The outer cap member has a plurality of licking wedges disposed on its inner surface. The inner and outer cap members are assembled so as to permit mutual rotation. Thus, when the cap is emplaced over the open end of the container, the pins are received in the openings to thereby inhibit mutual rotation between the inner cap member and the container, thus sealing the inner glass member and providing access to its contents via a safety cap easy for adults and young adults to open but difficult or impossible for children to open. 
     The U.S. Pat. No. 4,746,017 discloses a protective safety container for encasing toxic drug filled glass vials is disclosed. The container includes a molded plastic body that is shaped to conform to the shape of a vial to be protected. A plurality of spaced longitudinal ribs are formed on the inner surface of the container body that act to engage the vial and hold it firmly in position, and also form a cushioning air space between the vial and the container. A molded plastic annular base is adapted to be snap fitted into the body such that the vial cannot be easily removed once it is secured within the container. Disposed in the top of the container is a small aperture having a frangible disk disposed therein. The disk may be removed so that a hypodermic needle may be inserted into a stopper in the vial to withdraw the vial&#39;s contents. The aperture is too small, however, to permit removal of the stopper itself. All of these features combine to provide a protective container for a glass vial. 
     The U.S. Pat. No. 4,300,612 discloses a solvent and shatter resistant protector for glass bottles containing hazardous materials. The protector is comprised of opaque or transparent polymeric material and conforms substantially to the shape of the container that is protected. The container protector is made up of top and bottom portions, each having respective cooperating means, such as a special threading arrangement, for separable engagement, which enables engagement to be maintained even in the event of shocks that are sufficient to damage the protected glass container. 
     The U.S. Pat. No. 3,982,716 discloses a holder for temporarily supporting a bottle containing hypodermically injected medication. The holder is magnetically attached to a supporting surface, and securely supports the bottle so that both hands of the user are free to manipulate a syringe to withdraw the proper dosage from the bottle. 
     The U.S. Pat. No. 3,604,584 discloses a method for protecting glass articles, such as jars and drinks bottles from abrasion by heat shrinking a thermoplastic material around a portion of the glass article.

     In making protective enclosure systems for open-ended tubes, a superior result may be achieved by using glass tubular members manufactured to highly precise specifications. While doing this enables the enclosure to be precisely manufactured to the specification of the tubular member and to thus achieve a packaging solution that includes little to no relative movement of the tubular member within the enclosure. For some implementations, the use of high precision incurs a cost that is higher than desired. This is in turn decreases a market acceptance of the solution. 
     Further, some applications may prefer different shapes of tubular members as compared to a glass tube with a flat circular bottom. For some applications or users, it may be preferable to provide a glass tube having a rounded arcuate bottom. For the level of protection afforded by products in this category, changing size, material, and/or shape of the tube significantly affects the enclosure. Thus a different arrangement for certain types of tubular members may be necessitated by changes in the tube, and vice-versa. 
     What is needed are alternatives to a successful protective assembly design set forth in incorporated U.S. Pat. No. 8,251,221 including alternatives providing for a wider range of options that can have reduced associated manufacturing costs.

The present invention is applicable to other protective systems, as well as protecting other types of containers. 
     In accordance with one embodiment, a reusable protective enclosure system incorporates and protects an open-ended tubular glass member. The enclosure system comprises a protective housing, containing a bore of such diameter to receive the tubular glass member and a cap member, the cap member is securely attached over the opening of the protective housing. The cap member is secured to the protective enclosure by use of a plurality of magnets oriented circumferentially around the axis of the bore in both the protective housing and the cap member. 
     A reusable protective enclosure system in its basic design includes: a) a protective housing containing a bore of such diameter and depth as to receive the tubular glass member, a protective collar, and b) a cap member.

Some implementations may include more than one spacer disposed in the space between the outer wall of the container and an inner surface of the bore. For example, two spacers may be distributed one hundred eighty degrees apart around the perimeter (in general, for a uniform distribution, each spacer of N number of spacers, N=0, 1, 2, 3, 4, 5, 6, or more, has an angular separation of 360/N (N greater than or equal to 1) degrees from the others). In other embodiments the spacers need not be uniformly distributed in this fashion. In these embodiments, appropriate space is collectively accounted for by the compressed thickness of the collective spacers.

     A method of protecting a tubular member, includes a) inserting said tubular member into a bore of a protective housing, said a tubular member having a first end, a second end opposite said first end and including a perimeter wall defining a cavity between one or more lateral walls extending from said second end, said tubular member further including an opening disposed in said first end accessing said cavity, wherein said second end includes a rounded bottom having an arcuate cross-section and said protective housing including: a) said bore in said protective housing of such diameter and depth as to accommodate insertion of said tubular member, said bore including an opening, a bottom opposite of said opening, and a first axis; b) a protective collar, said protective collar incorporated into said protective housing at said opening of said bore in said protective housing with said protective collar including a protrusion extending away from said protective housing; and c) a shock absorber coupled to said bottom of said bore; said shock absorber including a rounded cup portion complementary to said arcuate cross-section and a body portion coupled to said rounded cup portion, said shock absorber providing a protective cushion upon which said tubular member rests when said tubular member is inserted into said bore; and b) supporting said tubular member in said bore using said shock absorber; and c) securing a cap member to said protective housing producing a predictable airtight seal between said cap member and said protective housing, said cap member including; a) a bore of such diameter to completely accommodate insertion of said protective collar and said protrusion, and also encompassing said first end of said tubular member, said bore including a second axis; b) a top seal within said cap member; and c) a closure system securely coupling said cap member to said protective housing, said closure system including a first set of closure elements coupled to said cap member and a second set of closure elements coupled to said protective housing, said first set of closure elements complementary to said second set of closure elements with said closure elements repeatably and selectively engageable and disengageble securing said cap member to said protective housing. 
     A method described herein wherein a tubular width of said tubular member is less than a bore width of said opening of said bore; further comprising: d) adding a compressible spacer into said opening of said bore before said step a), said compressible spacer having a compressed thickness equal to a difference between said bore width and said tubular width, said spacer positioned at said first end between an outer portion of said tubular member and an inner portion of said bore, an extended portion of said spacer extending beyond said first end with said extended portion having a thickness greater than said compressed thickness; wherein said inserting step a) compresses a portion of said compressible spacer positioned between said tubular member and said bore. 
     A preferred means for achieving the objects of this invention include a protective housing containing a bore of such diameter and depth as to accommodate insertion and storage of a tubular glass member. At the mouth of the bore is a protective collar that protrudes from the top of the protective housing. When the tubular glass member is fully inserted into the bore in the protective housing, the open-end of the tubular glass member is slightly exposed above the protective collar before the cap member is attached. At the base of the bore in the protective housing is a concentric but substantially smaller diameter cylindrical recess. Seated within this cylindrical recess is a shock absorber, which protects the tubular glass member from breakage should the protective housing, cap member and tubular glass member be subjected to a shock. In addition, the shock absorber is mounted within the cylindrical recess to allow the tubular glass member, which rests upon it, to easily twist around its vertical axis when the cap member is attached and detached from the protective housing. The shock absorber also exerts upward pressure against the tubular glass member bottom when the cap member is attached, thus rendering a predictable and airtight seal between the gasket in the cap member and the tubular glass member. The protective housing also contains at least one pair of circumferentially oriented cavities. Such cavities are positioned axially from the center of said bore and are proximal to the protective collar. Each cavity contains a permanently affixed magnet. 
     The protective enclosure system also includes cap member. The cap member incorporates a bore of such diameter as to accommodate the protective collar in the protective housing when the cap member is attached to the protective housing. At the closed-end of the bore in the cap member, is a replaceable rubber gasket, which is held in place due to the fact that its diameter is slightly larger than the diameter of the bore in which it sits. The rubber gasket ensures that the contents of the glass member are under a predictable airtight seal when the cap member and protective housing are attached to one another. The rubber gasket also provides a degree of shock absorption to protect the tubular glass member should the enclosure system suffer a fall or sudden jolt. The body of the cap member also contains at least one pair of circumferentially oriented cavities. Each cavity contains a permanently affixed magnet. Each magnet is positioned axially from the center of the bore in the cap member. Each magnet is proximal to the bore&#39;s opening in the cap member. 
     With this configuration, when the cap member is coaxially aligned over the protective housing, a magnetic attraction pulls the protective housing and cap member tightly and securely together. The magnetic force creates a predictable airtight seal wherein the protective collar in the protective housing and the slightly exposed portion of the tubular glass member are forced into the rubber gasket within the cap member and vice versa. Simultaneously, the shock absorber at base of the protective housing exerts an upward force against the closed-end of the tubular glass member further ensuring an airtight seal wherein the open-end of the tubular glass member is forced into the gasket in the cap member. 
     When desired, the cap member and the protective housing can be separated and the airtight seal easily broken. The cap and housing are separated by holding the protective housing in one hand, while radially twisting the cap member with the other hand. This twisting action distances the plurality of magnets in the protective housing from the magnets in the cap member, allowing the cap member to be easily lifted up and away from the protective housing. Once the cap member and protective housing are separated, the contents of the tubular glass member are readily accessible. Separation of the cap member from the protective housing also allows for easy removal of the tubular glass member from within the protective housing. Once the cap and protective housing have been separated the tubular glass member can be removed, washed, sterilized and entirely replaced and recycled. 
     It is therefore a broad object of this invention to provide an improved reusable protective enclosure system for a tubular glass member.

     DETAILED DESCRIPTION OF THE INVENTION 
     Embodiments of the present invention provide a system and method for are alternatives to a successful protective assembly design set forth in incorporated U.S. Pat. No. 8,251,221 including alternatives providing for a wider range of options that can have reduced associated manufacturing costs. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. 
     Various modifications to the preferred embodiment and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein. 
     DEFINITIONS 
     The following definitions apply to some of the aspects described with respect to some embodiments of the invention. These definitions may likewise be expanded upon herein. 
     As used herein, the term “or” is generally intended to mean “and/or” unless otherwise indicated. 
     As used herein, the singular terms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an object can include multiple objects unless the context clearly dictates otherwise. 
     Also, as used in the description herein and throughout the claims that follow, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise. 
     As used herein, the term “set” refers to a collection of one or more objects. Thus, for example, a set of objects can include a single object or multiple objects. Objects of a set also can be referred to as members of the set. Objects of a set can be the same or different. In some instances, objects of a set can share one or more common properties. 
     As used herein, the term “adjacent” refers to being near or adjoining. Adjacent objects can be spaced apart from one another or can be in actual or direct contact with one another. In some instances, adjacent objects can be coupled to one another or can be formed integrally with one another. 
     As used herein, the terms “connect,” “connected,” and “connecting” refer to a direct attachment or link. Connected objects have no or no substantial intermediary object or set of objects, as the context indicates. 
     As used herein, the terms “couple,” “coupled,” and “coupling” refer to an operational connection or linking. Coupled objects can be directly connected to one another or can be indirectly connected to one another, such as via an intermediary set of objects. 
     As used herein, the terms “approximate” and “approximately” in the context of embodiments of the present invention includes a scope of statistical variation of a particular variable that the subsequently described event or circumstance may or may not occur, and for some implementations of the present invention corresponds to ±20% about the statistically prescribed value. Without context to the contrary, the use of the term “about” means approximately. 
     As used herein, the terms “substantially” and “substantial” refer to a considerable degree or extent. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation, such as accounting for typical tolerance levels or variability of the embodiments described herein. 
     As used herein, the terms “optional” and “optionally” mean that the subsequently described event or circumstance may or may not occur and that the description includes instances where the event or circumstance occurs and instances in which it does not. 
     As used herein, the term “size” refers to a characteristic dimension of an object. Thus, for example, a size of an object that is spherical can refer to a diameter of the object. In the case of an object that is non-spherical, a size of the non-spherical object can refer to a diameter of a corresponding spherical object, where the corresponding spherical object exhibits or has a particular set of derivable or measurable properties that are substantially the same as those of the non-spherical object. Thus, for example, a size of a non-spherical object can refer to a diameter of a corresponding spherical object that exhibits light scattering or other properties that are substantially the same as those of the non-spherical object. Alternatively, or in conjunction, a size of a non-spherical object can refer to an average of various orthogonal dimensions of the object. Thus, for example, a size of an object that is a spheroidal can refer to an average of a major axis and a minor axis of the object. When referring to a set of objects as having a particular size, it is contemplated that the objects can have a distribution of sizes around the particular size. Thus, as used herein, a size of a set of objects can refer to a typical size of a distribution of sizes, such as an average size, a median size, or a peak size. 
       FIG. 1-FIG .  6  illustrate an embodiment of the reusable protective enclosure system for an open-ended tubular member.  FIG. 1  shows one embodiment of a reusable protective enclosure system for an open-ended tubular glass member. The reusable protective enclosure system incorporates a cap member  12 . The cap member  12  has a bore  32  centered on an axis  30 . The reusable protective enclosure system also incorporates a protective housing  20 . The protective housing also incorporates a bore  32 . The bore  32  in cap member  12  and the bore  32  in the protective housing  20  share a common axis  30  when attached to one another. The bore  32  in both the protective housing  20  and the cap member  12  together form a cavity  34  with a common axis  30 . At the base of the bore  32  and proximal to the protective housing bottom  24  is a recess  36 . The recess  36  is centered on axis  30 . A sectional view of a reusable protective enclosure system for an open-ended tubular glass member is provided via  FIG. 6 . 
       FIG. 2  is a perspective view of the protective housing for a tubular glass member. A tubular glass member  50  is seated within the cavity  34  created by the bore  32  in the protective housing  20 . The tubular glass member open end  52  is exposed slightly above the protective collar  38 . Two magnets  44  are positioned axially and permanently embedded in the protective housing top  22 . The tubular glass member closed end  54  rests on a shock absorber  40 . The shock absorber  40  sits within the recess  36  in the protective housing bottom  24 . 
       FIG. 3  is a perspective view of the cap member  12 . The cap member  12  incorporates a bore  32 , which extends into the cap member  12 . The bore  32  in the cap member  12  creates a cavity  34 , which extends toward, but does not pass through the cap member top  14 . Two magnets  44  are positioned axially from the center of the bore  32  in the cap member bottom  16 . 
       FIG. 4  is a perspective view of the tubular glass member  50 . The tubular glass member  50  incorporates a tubular glass member open end  52  and a tubular glass member closed end  54 . 
       FIG. 5  is a side view of the cap member  12 . The cap member  12  incorporates a cap member top  14 . A bore  32  with an opening at the cap member bottom  16  creates a cavity  34  that extends toward but does not pierce the cap member top  14 . A gasket  42  rests within the bore  32  proximal to the cap member top  14 . 
       FIG. 6  is a sectional view taken from  FIG. 1 . Proximal to the protective housing bottom  24  is a recess  36  into which is inserted a shock absorber  40 . The tubular member closed end  54  rests upon the shock absorber  40 . The tubular glass member  50  occupies the cavity  34  within the protective housing  20  and the cap member  12 . Sidewall cushioning  48  is positioned circumferentially within the protective housing  20  adjacent to and contacting the tubular glass member  50 . Magnets  44  are embedded equidistant and radially from axis  30  in the protective housing top  22  and the cap member bottom  16 . A predictable airtight seal  46  is formed where the gasket  42 , protective collar  38  and glass member open end  52  intersect and are forced into contact by the magnets  44  in the protective housing  20  and the cap member  12 . 
     To store and protect contents, such as cosmetics, medicines, natural remedies and essential oils within an airtight seal, one must first place these materials within the tubular glass member  50  ( FIG. 4 ). Such contents may be placed within the tubular glass member  50  ( FIG. 4 ) while it is free standing or when it sits in the protective housing  20  ( FIG. 2 ). To seal and protect said contents within the tubular glass member  50 , the tubular glass member  50  is inserted in the cavity  34  within the protective housing  20  ( FIG. 2 ). Next one aligns the cap member  12  ( FIG. 3 ) with the cap member bottom  16  over the protective housing top  22  ( FIG. 2 ). When properly oriented, such that the magnets  44  in the cap member bottom  16  ( FIG. 3 ) and magnets in the protective housing top  22  ( FIG. 2 ) face one another, magnetic attraction will force the cap member bottom  16  and the protective housing top  22  into one another. By virtue of the attractive force exerted by the magnets  44  in the cap member  12  and protective housing  20  an airtight seal  46  ( FIG. 6 ) is formed where the tubular glass member open end  52  and protective collar  38  and the gasket  42  within the cap member  12  intersect ( FIG. 6 ). This airtight seal  46  is augmented by the upward force created by the shock absorber  40  ( FIG. 6 ) pushing against the tubular glass member closed end  54 , thus maintaining pressure between the tubular glass member and the gasket  42  ( FIG. 6 ). 
     To access the contents stored under airtight seal  46  within the tubular glass member  50 , one must grip the protective housing  20  with one hand and then radially twists the cap member  12  with the other hand. This twisting motion causes the cap member  12  to twist radially around the protective collar  38  causing the magnets  44  in the cap member bottom  16  to be distanced from the magnets  44  in the protective housing top  22 , thus breaking their attractive bond. Once the magnetic force is released the cap member  12  can be easily removed from the protective housing  20 . With the cap member  12  ( FIG. 3 ) and protective housing  20  ( FIG. 2 ) separated, the contents of the tubular glass member  50  ( FIG. 2 ) are readily accessible. Now the tubular glass member  50  ( FIG. 4 ) can be removed from the protective housing  20  ( FIG. 2 ) for sterilization or recycling. If desired the gasket  42  ( FIG. 5 ) can also be removed or replaced as needed. 
     Thus, the advantages of the protective housing include storing cosmetics, medicines, natural remedies and essential oils within a portable glass lined container, protected from shock and under an airtight seal. In addition, the glass lined container can is easily removed for cleaning, sterilization or recycling. 
       FIG. 7-FIG .  9  relate to an alternate embodiment of the reusable protective enclosure system  700  for an open-ended tubular member similar to member  50  referenced in  FIG. 1-FIG .  6 .  FIG. 7  illustrates a side view of an alternate embodiment of the reusable protective enclosure system for an open-ended tubular member illustrated in  FIG. 1-FIG .  6 .  FIG. 8  illustrates a sectional view of the alternate embodiment illustrated in  FIG. 7  along Section A-A.  FIG. 9  illustrates an exploded view of the alternate embodiment illustrated in  FIG. 7 . System  700  is similar to structure, arrangement, and operation as the system illustrated in  FIG. 1-FIG .  6  with the exception that cap member  12  and housing  20  have a cylindrical cross-section as opposed to the square cross-section otherwise illustrated. System  700  includes a cap  705  and a protective housing  710  securing a jar  805 . An elastomeric bottom seal  810  provides cushioning as described in the context of shock absorber  40 . A cap assembly includes cap  705 , a top seal  815 , and a slip disc  820  between cap  705  and top seal  815 . Top seal  815  closes off an opening of jar  805  to seal the opening closed and to secure contents of jar  805  inside. As illustrated, cap  705  and housing  710  are made of recycled high-density polyethylene (HDPE), jar  805  is made of glass, bottom seal  810  and top seal  815  are made of silicone rubber, and slip disc  820  is made of any of a variety of sturdy materials (e.g., polyethylene) that achieve the result of allowing cap  705  to rotate relative to top seal  815  (i.e., slip). This situation exists as cap  705  is secured using a rotational locking system (e.g., threads) to attach to housing  710 . While rotating cap  705  onto housing  710 , a bottom surface of top seal  815  engages and closes a perimeter of the opening of jar  805 . Top seal  815  tends to become fixed relative to jar  805  while cap  705  rotates about aligned longitudinal axes of housing  710  and jar  805 . Cap  705  preferably moves relative to a stop surface of top seal  815  which tends to try to rotate top seal  815  while the coupling of jar  805  to top seal  815  tends to resist rotation. Slip disc  820  is interposed to address this problem and provides a mechanism by which cap  705  can “slip” past top seal  815  during rotation. Slip disc  820  does not easily wear out and allows top seal  815  to rotate relative to cap  705 . 
       FIG. 10-FIG .  12  relate to an alternate embodiment of the reusable protective enclosure system  1000  for an open-ended tubular member  1105 , sometimes alternatively referred to as a jar, container, and the like, similar to member  50  referenced in  FIG. 1-FIG .  6  and jar  805  referenced in  FIG. 7-FIG .  9  except that a bottom of member  1105  is rounded in contrast to a flat bottom of member  50  and jar  805 .  FIG. 10  illustrates a side view of another alternate embodiment of the reusable protective enclosure systems for an open-ended tubular member illustrated in  FIG. 1-FIG .  9 .  FIG. 11  illustrates a sectional view of the alternate embodiment illustrated in  FIG. 10  along Section B-B.  FIG. 12  illustrates an exploded view of the alternate embodiment illustrated in  FIG. 10 . System  1100  is similar to structure, arrangement, and operation as the system illustrated in  FIG. 1-FIG .  6  and system  700  illustrated in  FIG. 7-FIG .  9 , the housing and cap having a circular, square, or other cross-section, with the exception of the rounded bottom and implicated support structures. System  1000  includes a cap  1005  and a protective housing  1010  securing a jar  1105 . An elastomeric conical bottom seal  1110  provides cushioning as described in the context of shock absorber  40  and bottom seal  810 . A cap assembly includes cap  1005 , a top seal  1115 , and a slip disc  1120  between cap  1005  and top seal  1115 . Top seal  1115  closes off an opening of jar  1105  to seal the opening closed and to secure contents of jar  1105  inside. As illustrated, cap  1005  and housing  1010  are made of recycled high-density polyethylene (HDPE), jar  1105  is made of glass, bottom seal  1110  and top seal  1115  are made of silicone rubber, and slip disc  1120  is made of any of a variety of sturdy materials (e.g., polyethylene) that achieve the result of allowing cap  1005  to rotate relative to top seal  1115  (i.e., slip) similarly as described in the context of  FIG. 7-FIG .  9 . 
     Bottom seal  1110  may, in some implementations, provide a suction-cup attachment portion coupled to a body portion: the suction-cup attachment portion engages and holds an outside bottom portion of rounded bottom  1125  of jar  1105  and supports it to suspend jar  1105  safely to cushion it. A bottom portion  1130  of housing  1010  is rounded closely complementary to rounded bottom  1115  to support portions of rounded bottom  1125  spaced away from a contact location where bottom seal  1110  makes physical contact. The body portion of bottom seal  1110  includes an extension  1135  mated into a complementary cavity of bottom portion  1130 . In some implementations, extension  1135  is press-fit, contact-fit, screwed, inserted, or otherwise placed into bottom portion  1130  and held in place sufficiently that removal of jar  1105  from within housing  1010  does not also remove bottom seal  1110  from within housing  1010 . Bottom seal  1110  varies as to materials used, size, and a coverage area of rounded bottom  1125  to achieve the desired level of jar-protecting force absorption. 
       FIG. 13  illustrates a protective system  1300  using a spacer  1305 . Protective system  1300  may be incorporated into a variety of systems, including the designs, embodiments, and implementations described herein. One design that provides exceptional levels of protection that reduce risks of breaking a protected jar disposed in one of the protective systems is providing very close tolerances for an outside surface of the jar and an inside surface of the bore of the housing. There may be several reasons why this arrangement reduces the risks of breakage, including possibilities such as reducing motion of the jar inside the bore or increasing a frictional force between an outside surface of the wall of the jar and an inside surface of the bore of the housing which may not only reduces motion but provide axial damping. 
     It has been observed that implementations having looser tolerances have a greater risk of damage to the jar than those having tighter standards. However, making jars with highly precise dimensions and creating bores with dimensions closely matching those of the jars can greatly increase costs. Protective system  1300  provides improved protection while loosening manufacturing tolerances. Protective system  1300  does this by purposefully making an outer diameter D 1  of a jar  1310  smaller than an inner diameter D 2  of a bore  1315  of a housing  1320 . This creates a greater than desired lateral space around an outside of the lateral wall(s) of jar  1310 . Spacer  1305  is provided in this lateral space to secure jar  1310  within bore  1315 . Spacer  1305  may be a simple removeable strip or other structure that is cloth, felt, elastomer, or other material interposed at a top opening of bore  1315  between housing  1320  and a top opening of jar  1310 . Preferably spacer  1305  is mildly compressive and thicker than a difference D d  between D 2  and D 1 . In this context, mildly compressive refers to interstitial placement of a thicker-than-D d  spacer  1305  without risk of breaking or cracking while also providing a desired level of lateral support. 
     One effect of this is to mis-align a longitudinal axis  1325  of jar  1310  from a longitudinal axis  1330  of bore  1315  (the misalignment arising from either lateral displacement of the jar relative to the bore, a tilting of the jar within the bore, or a combination of both depending upon an arrangement and orientation of the components). Spacer  1305  reduces a breakage risk associated with placing an intentionally reduced diameter jar  1310  inside bore  1315 .  FIG. 1-FIG .  6  also provide a spacer system that can be configured to achieve a similar function. 
     A reusable protective enclosure system for an open-ended tubular member may be made from a wide variety of materials. For example the protective housing and cap member could be formed from a variety of moldable polymerized compounds (e.g., plastic), metals, ceramics, glass, cellulose (e.g., wood, compressed paper, and the like), and rigid elastomers (e.g., natural or synthetic rubber) materials. 
     It is not always the case that the entire jar is made of glass. In some implementations, protective system may be used to protect an open-ended tubular member having multiple layers, such as an inner glass layer coated with a non-glass material, while other scenarios may employ some other materials which may not be glass. There is an advantage in embodiments of the present invention in protecting and securing containers made of amorphous solid material (e.g., glass), particularly in protecting and securing them during handling including transportation. 
     Reusable protective enclosure systems for an open-ended tubular member can be built in a wide range of sizes. The protective housing, cap member and tubular glass member could be formed to fit in a user&#39;s pocket to store and transport relatively small volumes of material. In addition, protective enclosure systems could be made for use in the home, in larger sizes, to accommodate much greater volumes of cosmetics, medications, natural remedies, tinctures and oils. Embodiments of the present invention are quite scalable between these various implementations and uses. 
     Reusable protective enclosure systems for an open-ended tubular member can be manufactured using a variety of methods. The protective housing, cap member could be fabricated using highly automated assembly processes in large volumes, via injection molding of plastic or automated milling of metallic or ceramic substances. Alternatively, the protective housing and cap member could be hand crafted by artisans with hand tools, thus creating highly decorative and unique and artistic forms in which the tubular glass member could be enclosed. 
     A reusable protective enclosure systems for an open-ended tubular member can be built in a wide range of configurations. For example the sidewalls of the bore in the protective housing and cap member could incorporate embedded cushioning for additional shock protection to protect the tubular glass member. One or more o-rings or gaskets, seated within channels cut into the protective housing and cap member could provide additional shock protection for the glass member. Or a plurality of soft protrusions inserted into the sidewalls of the rigid protective member and the cap member could also offer additional shock absorption. In addition, the glass member could be sheathed in a soft protective sleeve, both of which would be inserted within the protective housing. In situations where a dry substance is stored within the enclosure system, the glass member, and any other elements within the bore could be removed entirely, for a simplified yet airtight and effective enclosure. And, the recess and shock absorber in the base of the protective housing could be replaced by a conical or multi-wave spring, which would simply be inserted in the base of the bore within the protective housing. In addition the cap member and protective housing may be attached and an airtight seal formed within the tubular member by means of threads in the cap member and protective housing.
