in fig1 is shown the dispensing closure of the present invention generally indicated by the numeral 10 . closure 10 is shown attached to the neck 12 of container 11 . the closure of this invention consists primarily of two elements . the first or outer element is a sleeve generally indicated by the numeral 15 . sleeve 15 can be seen in fig1 and 2 , and in detail in fig3 - 5 . the second element is an insert generally indicated by the numeral 25 . the insert can be seen in fig1 and 2 , and in detail in fig6 - 9 . insert 25 has a lower cylindrical portion 26 and an upper cylindrical portion 27 . the lower cylindrical portion 26 has threads 28 on the inside thereof which permit the insert 25 to be screwed onto the neck 12 of the container 11 as shown in fig1 and 2 . the neck 12 of the container must , of course , be threaded to mate with threads 28 in insert 25 . the upper portion 27 of insert 25 has threads 29 on the outside thereof which are adapted to engage threads 16 in the interior of sleeve 15 . on the inside of the upper cylindrical portion 27 is an inner retaining ring 30 which extends inwardly from the upper end of the side wall of upper cylindrical portion 27 . extending upwardly from the lower cylindrical portion 26 is an interior cylinder 34 . interior cylinder 34 has a series of openings 35 in the top thereof and a solid post 36 extending upwardly therefrom . referring now to fig3 - 5 , the sleeve of the invention is generally indicated by the numeral 15 in fig3 . sleeve 15 is a cylindrical cap having a top 17 with an orifice 18 therein . extending downwardly from the top 17 of sleeve 15 is an inner cylinder 19 . inner cylinder 19 has a retaining ring 20 on the outside bottom end thereof which can be snap - fitted inside of retaining ring 30 in the interior of the upper cylindrical portion 27 of insert 25 , as shown in fig1 and 2 . also extending downwardly from the top 17 of sleeve 15 is an intermediate cylinder 21 . intermediate cylinder 21 completely encloses the inner cylinder 19 . on the interior wall of intermediate cylinder 21 are a series of threads 16 which engage threads 29 on the outside of the upper cylindrical portion 27 of insert 25 . referring now to fig1 and 2 , the closure of the present invention is shown assembled on top of a container 11 . insert 25 is screwed onto neck 12 of the container which has threads ( not shown ) thereon . however , if desired , insert 25 can be attached to container 11 by any well - known means in the art such as by gluing , snapping , welding , or the like . after insert 25 is firmly attached to container 11 , sleeve 15 is fitted thereon by aligning the inner cylinder 19 of sleeve 15 with the upper cylindrical portion 27 of insert 25 . after alignment is achieved , sleeve 15 is forced downwardly thereby causing ring 20 to slip into the interior of upper cylindrical portion 27 . upper cylindrical portion 27 must , of course , flex outwardly to allow inner cylinder 19 and ring 20 thereon to slip inside of ring 30 or upper cylindrical portion 27 . in the position shown in fig1 the closure of the invention is in the dispensing mode . by inverting container 11 and / or squeezing the container if it is flexible , the contents thereof travels through openings 35 , around post 36 , and out through orifice 18 . retaining ring 30 is shown to be in contact with the retaining ring 20 and sleeve 15 is shown to be in the upper - most position . to close the closure the sleeve 15 is forced downwardly and twisted clockwise to cause threads 16 in sleeve 15 to engage threads 29 on insert 25 . sleeve 15 is turned until the post 36 is forced upwardly into closure 18 to form a seal therewith while top 17 is forced downwardly onto the top of upper cylindrical portion 27 of insert 25 . the threads 16 are positioned relative to threads 29 such that after the threads are disengaged , the sleeve 15 rises off of the post 36 and spins freely . this eliminates the change of subjecting the insert 25 to any unwanted torque which might be encountered when turning the sleeve to a dispensing mode . as is apparent from above , rings 30 and 20 act as &# 34 ; o &# 34 ; rings or sealing rings . furthermore , they prevent the removal of the sleeve 15 from the insert 25 during normal use . although the preferred embodiments of the present invention have been disclosed and described in detail above , it should be understood that the invention is in no sense limited thereby and its scope is to be determined by that of the following claims :
