fig1 illustrates an exemplary container 10 , which may be a collapsible container , in an open position that includes a bottom panel 13 , two first side walls 16 , two second side walls 19 , a border reinforcement portion 23 , and one or more handles 26 . each of the first side walls 16 is adjoined to a corresponding first edge of the bottom panel 13 . each of the second side walls 19 is adjoined to a corresponding second edge of the bottom panel 13 . the border reinforcement portion 23 is , in this non - limiting example , attached to a top portion of the first side walls 16 and a top portion of the second side walls 19 . collapsible container 10 may be configured in any of a number of materials , as one of ordinary skill in the art would know . as nonlimiting examples , collapsible container may be configured of a fiber - based material , such as paper , plastic , fiberboard , cardboard , and / or any other material as described herein . in the non - limiting example shown in fig1 , the edge formed by second side wall 19 and bottom panel 13 is greater in length than the edge formed by first side wall 16 and side wall 19 . this dimension gives container 10 a rectangular box shape when open , that is , such that container 10 is wider than it is tall . it should be noted , however , that in another non - limiting example , the edge formed by second side wall 19 and bottom panel 13 may be substantially equal in length to the edge formed by first side wall 16 and side wall 19 . in this configuration , the bottom panel 13 may be substantially square . handles 26 may comprise apertures , straps , and / or other mechanisms for carrying the container 10 , as one of ordinary skill in the art would know . handles 26 may be secured to container 10 at border reinforcement portion 23 . instead of the handles 26 shown in fig1 , straps and / or other carrying / support mechanisms may be implemented , as one of ordinary skill in the art would know . the border reinforcement portion 23 may comprise a semi - rigid material , such as , for example , paperboard , cardboard , kraft paper , corrugated fiberboard , plastic , and / or other material . border reinforcement portion 23 may comprise one or more bonded pieces of material to provide added strength to container 10 . similarly , the bottom panel 13 may comprise a semi - rigid material , such as , for example , paperboard , cardboard , kraft board , corrugated fiberboard , and / or other material . in an open position , container 10 may exhibit qualities of a box in that container 10 and its portions , as described above , may provide rigid support for transporting and / or packaging objects , products , and / or other items . in this respect , the border reinforcement portion 23 may provide additional support for each of the first side walls 16 and each of the second side walls 19 such that the container 10 can generally obtain a box shape with additional shape stability . in this respect , the border reinforcement portion 23 may provide additional support to help to prevent and / or minimize tearing when the container 10 is carried using one or more handles 26 . as illustrated in the non - limiting example of fig1 , each of first side walls 16 may include a first fold line 29 . the first fold line 29 may extend along a central portion of the respective first side wall 16 . each of the first fold lines 29 in this non - limiting example may be substantially and / or approximately perpendicular to a respective first edge of the bottom panel 13 . in addition , each of the first side walls 16 may include two or more second fold lines 33 . each of the second fold lines 33 may extend diagonally from a corresponding corner of the respective first side wall 16 to the respective one of the first fold lines 29 . in addition , each of the first side walls 16 may also include a corresponding third fold line 34 . the third fold line 34 may extend parallel to a respective edge of the bottom panel 10 and intersect the respective fold line 29 at a central point . as a non - limiting alternative embodiment , container 10 may also include a support portion 14 that may be positioned inside container 10 on top of bottom panel 13 . support portion 14 may comprise materials of increased strength for supporting heavier loads in container 10 , such as , as a nonlimiting example , corrugated cardboard . support portion 14 may be configured to either be permanently attached to bottom panel 13 by , for example , glue or other fastening techniques , as one of ordinary skill in the art would know , or it may be configured to merely rest in the bottom of container 10 to be removed , as needed . fig2 illustrates an alternative view of the exemplary container 10 from fig1 . as illustrated in the non - limiting example of fig2 , the container 10 may include two second side walls 19 . each of the second side walls 19 may include a corresponding fourth fold line 36 . each of the fourth fold lines 36 may extend across the length of the respective second side wall 19 parallel . on first side wall 16 , the first fold lines 29 , the second fold lines 33 , third fold lines 34 and the fourth fold lines 36 are configured to make it easier to fold , collapse , expand , unfold , and / or otherwise manipulate the container 10 , as depicted in fig2 . as shown in the non - limiting example of fig2 , each of the first fold lines 29 enable the first side walls 16 to be folded inward towards the center of the container 10 . the second fold lines 33 enable the container 10 to be folded downward towards the bottom panel 13 . fig3 illustrates a collapsed view of the exemplary container 10 from fig1 . the third fold lines 34 ( shown in fig2 ) and the fourth fold lines 36 ( shown in fig2 ) enable the container 10 to be folded to a respective side of the bottom panel 10 and allow the container 10 to collapse and lay flat , as shown in the non - limiting example of fig3 . in this configuration , container 10 exhibits qualities of a foldable bag . one should also note that conditional language , such as , among others , “ can ,” “ could ,” “ might ,” or “ may ,” unless specifically stated otherwise , or otherwise understood within the context as used , is generally intended to convey that certain embodiments include , while other embodiments do not include , certain features , elements and / or steps . thus , such conditional language is not generally intended to imply that features , elements and / or steps are in any way required for one or more particular embodiments or that one or more particular embodiments necessarily include logic for deciding , with or without user input or prompting , whether these features , elements and / or steps are included or are to be performed in any particular embodiment . it should be emphasized that the above -
