DETAILED DESCRIPTION
As shown in FIG. 1, an embodiment of container 10 is provided in the form of a backpack for the retention, conveyance, and thermal control of a plurality of beverages or other perishables. Container 10 includes cover 12, framework 14, and thermal packs 15. Optionally, liner 16 may be employed in place of framework 14.
FIGS. 1 and 2 show an embodiment of cover 12 of container 10 suitable for receiving framework 14 or liner 16. Cover 12 includes insulated walls 17a-d, shoulder straps 18, 18a, hanging strap 20, top cover 22, front pockets 24, 26, side pockets 28, dispensing flaps 30, and liner retainers (not shown).
Shoulder straps 18, 18a are provided for carrying container 10 as a backpack. Shoulder straps 18, 18a are adjustable and include padded upper portions 19 and straps 21. Padded upper portions 19 are sewn or otherwise affixed to upper edge 43c of back wall 17c. Straps 21 are sewn or otherwise affixed to lower portions near the interface of back wall 17c and respective side walls 17b,d. Hanging strap 20 is provided by which container 10 may be hung such that the weight of container 10 is approximately evenly distributed on each side thereof (assuming substantially even payload distribution). Top cover 22 includes fixed end 34, access end 36, and a pair of sides 38 extending between fixed end 34 and access end 36. Fixed end 34 is sewn to insulated wall 17d. Access end 36 includes a strip of hook and loop fastener 40 that corresponds to a similarly sized strip of hook and loop fastener 42 coupled proximate upper edge 43b of insulated wall 17b. Each of sides 38 have one half of zipper 23 coupled thereto that mate with halves of zippers 23 on upper edges 43a,c of respective insulated walls 17a,c. Accordingly, top cover 22 can be lifted by access end 36 to open container 10 or top cover 22 can be secured by hook and loop fastener 42 and zippers 23 for closure. Strap 25 extends between zippers 23 such that pulling on strap 25 pulls both zippers 23.
Front pockets 24, 26 are positioned on the exterior of front insulated wall 17a. Pocket 24 includes outer wall 44 that is insulated. Outer wall 44 includes an area where signage may be stitched therein or otherwise affixed. Upper edge 46 and portions of side walls 48a,b have one half of zipper 47 coupled thereto that mate with a half of a zipper 47 on front insulated wall 17a to selectively close pocket 24. The interior of front pocket 24 forms a waterproof pouch. Pocket 26 is positioned on the exterior of outer wall 44. Pocket 26 is not waterproof and includes outer wall 50. Pocket 26 is selectively opened and closed via zipper 52.
Side pockets 28 each include mesh portions 54 and elastic portions 56. Mesh portions 54 are sewn to respective side walls 17b,d at lower ends 58 and sides 60. Upper ends 62 of mesh portions 54 are coupled to elastic portions 56. Elastic portions 56 expand when under load allowing mesh portions 54 to extend outward so that side pockets 28 may receive and retain items therein.
Dispensing flaps 30 are provided at the lower ends of side walls 17b,d and provide a portion of bottom 66 of cover 12. Dispensing flaps 30 are formed from an insulated wall. Dispensing flaps 30 are sewn or otherwise fixed to bottom 66. Sides 68 of dispensing flaps 30 have one half of zippers 70 thereon, with complementary sides of zippers 70 coupled to respective walls 17a,c. Strap 72a,b extends between zippers 70 such that pulling on strap 72a,b pulls both zippers 70 on respective flap 30. Inner side of upper ends 74 of flaps 30 include a strip of hook and loop fastener 76 thereon. Complementary strips of hook and loop fastener 76 are mounted on walls 17b,d. Accordingly, flaps 30 can be pulled by upper ends 74 after zippers 70 are pulled down to open flaps 30 or flaps 30 can be secured by hook and loop fasteners 76 and zippers 70 for closure.
Liner retainers (not shown) are strips of hook and loop fastener coupled to the interior of walls 17a-d. Liner retainers (not shown) are sized and positioned to couple to complementary hook and loop strips 78 on liner 16. Liner 16 is a waterproof pouch having dimensions substantially similar to the interior dimensions of container 10. Liner 16 is formed from a single sheet of waterproof material 82 that is sonically welded or otherwise coupled to form a watertight pouch having open upper edge 84. Hook and loop strips 78 are affixed to surround the outside of open upper edge 84.
Framework 14, as shown in FIGS. 3-6, includes two container guides 86 and six (6) spacing connectors 88. Container guides 86 and connectors 88 can be made from any material that is strong enough to hold many, such as twenty, typical filled beverage containers without significantly bending or breaking and is sufficiently light weight so as not to add a great weight when worn as a part of a backpack. Such suitable materials include aluminum or molded plastic such as polycarbonate, polypropylene, high density polyethylene or polystyrene. As shown, container guides 86 and connectors 88 are formed from injection molded plastic.
FIG. 4 shows container guide 86 that can be either a front or back framework component. Front and back container guides 86 are identical and can be produced in the same injection mold. Front and back container guides 86 are also symmetrical about central axis 90. Accordingly, only one side will be discussed with the understanding that identical structure is present on the opposite side.
The front and back container guides 86 each include substantially flat back wall 92. Ridges 94 and 96 extend substantially perpendicularly from back wall 92 to form first pathway 98, which extends downwardly from container receiving upper end 100 and ends at first shaped rigid member 104. Rigid member 104 is shaped to block the movement of containers in the absence of manipulation by an operator.
Ridges 96 and 108 form second pathway 110 that begins at container receiving upper end 100 and extends to merging location 112 at which second pathway 110 merges with first pathway 98. Ridge 108 ends at second rigid shaped member 114. Second rigid shaped member 114 is shaped and positioned so as to allow containers in second pathway 110 to merge into first pathway 98 when containers are in first pathway 98 only by moving laterally so that containers in second pathway 110 merge into first pathway 98 only when a highest container 33 in first pathway 98 is below merging location 112.
It should be appreciated that ridges 94 of the respective sides define a vertical gap 132 therebetween. Similarly, ridge 108 and side ridge 89 define a vertical gap 134 of a width similar to gap 132. Notches 136 are defined in back wall 92 near upper end 100 of each gap 132, 134. Gaps 132, 134 are sized to receive thermal packs 15 therein.
Each container guide 86 includes six spacing connector voids 87 therein. Spacing connector voids 87 are located on each side ridge 89 with one near upper end 100 and one near dispensing point 124, and on bottom 126. Spacing connector voids 87 are sized to receive spacing connectors 88 therein. Container guides 86 further include shoulders 128 (see FIG. 6) proximate connector voids 87 that engage lock shoulders 130 of spacing connectors 88 thereon.
As shown in FIG. 5, assembled container guides 86 are spaced apart by spacing connectors 88 that connect to form framework 14 for holding and dispensing cylindrical containers, such as cans 33 or bottles containing beverages. Spacing connectors 88 include body 138 and tabs 140. Body 138 is substantially flat and of any useful length, depending on the typical height of beverage cans 33 or bottles expected to be used in the resulting container 10. Tabs 140 include lock shoulders 130 sized and shaped to engage shoulders 128 of container guides 86. Alternatively, container guides 86 and spacing connectors 88 may be connected by any of a variety of well known fastening mechanisms and techniques, including riveting and ultrasonic welding. It should also be appreciated that the entire framework 14 could be injection molded as one piece.
Spacing connectors 88 hold container guides 86 sufficiently far apart to enable free movement of beverage containers down pathways 98, 110 while at the same time maintaining container guides 86 sufficiently close that movement of beverage containers down pathways 98, 110 is controlled by ridges 94, 96, 108. Spacing connectors 88 are between four and six inches in length. Each ridge 94, 96, 108 within each set of ridges is sufficiently far apart from the other to accommodate the diameter of a beverage can or bottle.
Thermal packs 15, as shown in FIG. 7, include hangers 118, pouches 120, and thermal gel 122. Hangers 118 are of a length to span between opposing back walls 92 and are sized to snugly fit in notches 136. Each pouch 120 is formed from flexible plastic and includes gel compartment 142 and hanger receiving portion 144. Gel compartment 142 is sealed to minimize escape of thermal gel 122 contained therein. Hanger receiving portion 144 is a doubled over portion that provides an opening through which hanger 118 may extend. Hanger receiving portion 144 and thermal packs 15 in general is of a width less than hangers 118 and framework 14. Ends 146 of hangers 118 are sized and shaped to engage notches 136. When hangers 118 are within hanger receiving portion 144 and ends 146 engage notches 136, thermal packs 15 hang within gaps 132, 134. This placement allows thermal packs 15 to be proximate any beverages stored in framework 14. Thermal packs 15 are placed in a freezer or otherwise extensively cooled prior to insertion into gaps 132, 134. Accordingly, thermal packs 15 cool stored beverages within framework 14.
Beverage containers are removed from the assembled framework 14, after opening dispensing flaps 30, by an operator by moving the selected container 33 upwardly over edge 104a of the first shaped rigid member 104.
FIG. 6 shows assembled framework 14 holding beverage cans 33 in first pathway 98, which descends from container receiving upper end 100 of framework 14 and curves into a downward sloping path 98a, ending at first rigid shaped member 104. Member 104 is formed by the upturned terminal portions of ridges 94 on both front and back container guides 86 and is shaped and positioned to stop progress of a beverage container, such as can 33, either when alone in framework 14 or when it is under pressure from the weight of additional cans 33 above it in first pathway 98-98a. The upturned and centrally opened shape of member 104 also allows easy removal of cans 33 from framework 14 by an upward pressure on can 33 in the area 148 between the upturned terminal portions of the ridges that form member 104.
A second line of beverage cans 33 is shown in FIG. 6 descending second pathway 110 defined by ridges 96, 108 on both the front and back container guides 86. Ridge 108 ends in second rigid shaped member 114 at location 112 where pathway 110 merges with pathway 98-98a. 
Member 114 is positioned to hold cylindrical containers 33 so that they will be blocked from feeding into pathway 98-98a when a container 33 occupies pathway 98-98a at location 112, but will feed easily into pathway 98-98a when no can or container 33 blocks lateral movement into that pathway 98-98a. The lateral movement of containers from pathway 110 into pathway 98-98a avoids the downward weight of the containers in pathway 110 against member 104 and facilitates removal of the containers from pathway 98a. 
FIG. 1 shows pack 10 with top cover 22 opened to show pathways 98, 110 defined by ridges 94, 96, 108. Dispensing flaps 30 are also opened to expose first shaped rigid member 104 and cans 33.
Framework 14 is removable from the interior of container 10. Removal of framework 14 and addition of liner 16 allows container 10 to function more like a traditional cooler. Waterproof liner 16 allows items and ice to be placed therein such that melting ice will not escape through dispensing flaps 30.
The present invention has been illustrated in terms of a backpack for carrying beverages in cans 33 or bottles. It will be understood, however, by those skilled in the art that the device disclosed here for controlling the movement of generally cylindrical shapes in merging, descending pathways to avoid gridlock or jamming of the shapes at the point of merging and to avoid excessive weight on the lowermost such shape will have wide application and is intended to be within the scope of the appended claims. Likewise, a device for holding generally cylindrical shapes in single or multiple descending pathways such that the final such shape can be removed with a relatively small upward pressure will have many applications, each of which are intended to be within the scope of the appended claims.
