Abstract
A portable soft sided insulated container has an impermeable liner that provides a liquid holding barrier. The liner is folded from a single monolithic plastic sheet to reduce or eliminate the need for heat welded seams. The liner seats within the container and has a releasable attachment around its lip for mating with the rim of the container. The container has an insulated lid so that the entire assembly may be closed. The liner can be removed for cleaning, or replacement if punctured. When not in use the entire assembly can be folded into a collapsed position for storage.
Claims22
A combination comprising:
- a soft-sided insulated container, and a removable liner for placement inside said container, said liner being folded from a monolithic sheet of liner stock to define a chamber, capable of holding liquids, said liner being free of heat welded seams.
A combination comprising:
- a soft sided insulated container;
- and
- a removable liner for placement inside said container, said liner being formed from a water impermeable plastic sheet, said sheet having a periphery;
- said liner having a quadrilateral base and four sides extending from said base to define a chamber therebetween capable of holding water;
- each of said sides being joined to said base at a base edge;
- each of said sides having a pair of lateral edges each meeting said base edge at a corner;
- each of said sides having an edge opposed to said base edge and meeting each of said lateral edges at a corner;
- said sheet having corner portions defined between
- (a) adjacent lateral edges of two of said sides, and
- (b) said periphery and said corner positions are folded to lie against said sides.
A combination comprising:
- a soft sided insulated container, and
- a removable liner for placement inside said container,
- said liner being formed from a water impermeable plastic sheet;
- said sheet having a periphery;
- said liner having a rectangular base and four sides extending from said base to form a chamber therebetween, each of said sides being joined to said base at a base edge;
- said sheet being folded on a first pair of parallel fold lines to define one pair of said base edges;
- said sheet being folded on a second pair of fold lines to define the remainder of said edges;
- said sheet having four corner portions each defined between
- (a) an end portion of one of said first pair of fold lines;
- (b) an adjacent end portion of one of said second pair of fold lines, and
- (c) said periphery;
- and
- said corner portions are folded to lie against said sides.
