Abstract

Abstract A cushioned container for beverage cans and the like is formed from flexible, semi-rigid foamed material. An arched, one-piece roof panel and substantially planar bottom, back and front panels are bonded along their respective margins utilizing miter joints. The arched subchamber formed in the top of the container has flat surface areas formed in the arch for attaching removable coolant packages. The upper portion of the front panel of the container includes a tongue-shaped flap with beveled edges around its margin for releasable engagement with the corresponding beveled edges on the margin of the arched roof panel. The semi-rigid container fits within a carrying bag having a closure adjacent the margin of the flap. The flap flexes outwardly along a hinge line reinforced by the bag construction. The bag includes a collapsible lower compartment having a padded rear panel and an auxiliary strap useful for carrying or as a backpack hip strap.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 104 words
A thermally insulated, portable container assembly comprising a flexible outer carrying bag and an inner container adapted to be positioned within said outer bag; said inner container including walls being formed of flexible insulating material to provide an insulated chamber; a flexible flap member integrally forming a portion of one of the chamber walls, said flap member being displaceable to provide access to the interior of the inner container; sealing means for sealing said flap member to the adjacent edges of said inner container; and said carrying bag including a displaceable flap portion adjacent to the displaceable flexible flap member of said inner container.
Claim 2
Dependent Claim 104 words
A thermally insulated, portable container assembly comprising a flexible outer carrying bag and an inner container adapted to be positioned within said outer bag; said inner container including walls being formed of flexible insulating material to provide an insulated chamber; a flexible flap member integrally forming a portion of one of the chamber walls, said flap member being displaceable to provide access to the interior of the inner container; sealing means for sealing said flap member to the adjacent edges of said inner container; and said carrying bag including a displaceable flap portion adjacent to the displaceable flexible flap member of said inner container.
Claim 3
Dependent Claim 45 words
The portable container assembly of claim 1 wherein said container chamber has an upper and a lower portion, with the flexible flap member formed in the upper portion, and wherein the upper portion of the chamber includes means for positioning a removable coolant module therein.
Claim 4
Dependent Claim 202 words
A self-supporting, thermally insulated, portable container, comprising: a rectangular bottom panel formed from a sheet of semi-rigid insulating material and having opposed side margins and front and rear margins; a roof panel formed from a rectangular sheet of semi-rigid insulating material and having a curved midsection with two opposite spaced-apart arms, with the free ends of said spaced-apart arms bonded respectively to the side margins of said bottom panel; a back wall panel formed from a sheet of semi-rigid insulating material having the margins thereof conforming to the curved midsection and oppositely spaced apart arms and bonded thereto along the margins therebetween; a front wall panel formed from a sheet of semi-rigid insulating material having a lower rectangular area bonded along its outer margins to the front margins of said bottom panel and oppositely spaced arms to form a substantially rectangular chamber in the lower part of the container, the upper area of the front wall panel forming a flap movable between a closed position forming with the curved midsection of the roof panel an arched upper chamber in said container, said flap bendable away from said container to a second opened position to provide access to the interior of said container.
Claim 5
Dependent Claim 202 words
A self-supporting, thermally insulated, portable container, comprising: a rectangular bottom panel formed from a sheet of semi-rigid insulating material and having opposed side margins and front and rear margins; a roof panel formed from a rectangular sheet of semi-rigid insulating material and having a curved midsection with two opposite spaced-apart arms, with the free ends of said spaced-apart arms bonded respectively to the side margins of said bottom panel; a back wall panel formed from a sheet of semi-rigid insulating material having the margins thereof conforming to the curved midsection and oppositely spaced apart arms and bonded thereto along the margins therebetween; a front wall panel formed from a sheet of semi-rigid insulating material having a lower rectangular area bonded along its outer margins to the front margins of said bottom panel and oppositely spaced arms to form a substantially rectangular chamber in the lower part of the container, the upper area of the front wall panel forming a flap movable between a closed position forming with the curved midsection of the roof panel an arched upper chamber in said container, said flap bendable away from said container to a second opened position to provide access to the interior of said container.
Claim 6
Dependent Claim 15 words
The container of claim 3 wherein the semi-rigid insulating material is a flexible closed-cell material.
Claim 7
Dependent Claim 16 words
The container of claim 3 wherein respective panels are bonded together using double-sided adhesive transfer tape.
Claim 8
Dependent Claim 17 words
The container of claim 3, including means for positioning a removable cooling module in the upper chamber.
