Portable insulated container

Claim 2

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

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

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

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

The container of claim 3 wherein the semi-rigid insulating material is a flexible closed-cell material.

Claim 7

The container of claim 3 wherein respective panels are bonded together using double-sided adhesive transfer tape.

Claim 8

The container of claim 3, including means for positioning a removable cooling module in the upper chamber.

Claim 9

The container of claim 3, including a strip of flexible material positioned along the margin of the flap and providing a seal for the container when the flap is in the closed position.

Claim 10

The container of claim 3 wherein the margins of the bottom panel, the roof panel and the front wall panel are correspondingly beveled to form miter joints.

Claim 11

The container of claim 8 wherein the beveled margins of the miter joints are each formed at angles less than 45 degrees so that the insulating material is compressed at the inside of the joint and tensioned at the outside of the joint to provide contact between the adjacent beveled margins.

Claim 12

The container of claim 3, including closure means located between the front margin of the curved midsection and the flap margin for removably fastening the flap margin to the curved midsection, said closure means including strips of materials which releasably adhere when pressed together.

Claim 13

The container of claim 3, including a flexible carrying bag for receiving said container and including a closure means formed in said bag adjacent to the (container sealing means) flap allowing access thereto, said closure means terminating such that the bag structure reinforces the bendable region of said container and flap.
