Abstract A backpack cooler utilizes an insulated foam core that is covered on the outside with a cloth sheath and has a rigid reinforcing liner which defines a well to hold two stacked six packs of 12 ounce containers. The cloth jacket is retained to the rest of the cooler body by means of a retainer cord that fits into a peripheral retainer groove defined in the foam core, and a pair of shoulder straps fasten to the cloth jacket by means of a lateral pin that engages in a looped channel defined in the upper edge of the cloth jacket. The pin lies in a cavity defined in the foam core of the cooler body adjacent the retainer groove to prevent axial migration of the pin. The entire structure is strong enough to support the weight of a person, so that it doubles as a seat. Also, whereas the primary thrust of the invention is the accommodation of six packs of beer or sodas in twelve ounce cans, there is also an uninsulated accessory pouch defined by the jacket of the preferred embodiment to carry miscellaneous items.
A backpack cooler construction comprising: (a) an open-topped insulated body defining a well for containing cold beverages while keeping them cold; (b) an insulated lid for covering the top of said body and maintaining said well substantially sealed from outside air; (c) said body having a rigid insert and a cloth jacket substantially covering said insert; (d) a pair of shoulder straps connected to said body and enabling a person to strap said body on his back for transport; (e) said rigid insert having an upper rim and an external circumferential retaining groove adjacent said rim; and, (f) said jacket defining an upper peripheral loop enclosing a retainer cord for engaging in said groove for retaining said jacket on said body.
