Abstract
A collapsible insulated bag designed to allow items retained within an inner pouch thereof to remain within predetermined temperature ranges for predetermined periods of time and wherein the bags are designed to be easily compressed or compacted for storage or shipment to end users. The bags include at least an outer reflective layer, an intermediate open foam layer and the inner pouch layer.
Claims20
An insulated shipping and/or storage bag having a bottom, walls, and an opening generally opposite the bottom, the bag consisting of:
- an outer layer;
- an intermediate insulating layer, said intermediate insulating layer consisting of at least one sheet of insulating material having a generally rectangular shape with cut outs at each of four corners of said generally rectangular shape and opposing cut outs generally centrally along opposite side edges of said generally rectangular shape so as to form (i) a middle portion between (ii) two side portions, and (iii) end portions opposite said middle portion, said cut outs enabling a free standing configuration whereby said intermediate insulating layer is folded centrally thereof so that said middle portion becomes the bottom, said side portions become the walls, and said end portions extend along opposing edges of said opening of the bag;
- an inner plastic layer, said inner plastic layer being secured or welded to said outer layer of said bag with said end portions of said intermediate insulating layer extending along opposing edges of said opening;
- and
- a bag closure capable of at least partially closing said opening, said bag closure being selected from the group consisting of a mechanical zip-like closure, a double sided tape, a pressure closure, a taping closure, a flap with re-sealable taping means, and a flap with peel-off taping means.

An insulated shipping and/or storage bag having a bottom, walls, and an opening generally opposite the bottom, the bag consisting of:
- an outer layer forming a first major outer bag surface and a second major outer bag surface opposite said first major outer bag surface;
- an inner plastic layer that is configured to form a first major inner bag surface and a second major inner bag surface opposite said first major inner bag surface, said first major inner bag surface and said second major inner bag surface forming an article receiving pouch, said inner plastic layer being secured or welded to said outer layer;
- an intermediate insulating layer positioned between said outer layer and said inner plastic layer, said intermediate insulating layer consisting of at least one sheet of insulating material having (a) a first insulating material end portion positioned along said opening and extending within a first space between (i) said first major outer bag surface and (ii) said first major inner bag surface and (b) a second insulating material end portion positioned along said opening and extending within a second space between (i) said second major outer bag surface and (ii) said second major inner bag surface, each of said first insulating material end portion and said second insulating material end portion consisting of rectilinear cut outs at opposite corners thereof along said opening;
- and
- a bag closure capable of at least partially closing said opening.

- an outer layer forming a first major outer bag surface and a second major outer bag surface opposite said first major outer bag surface;
- an inner plastic layer that is configured to form a first major inner bag surface and a second major inner bag surface opposite said first major inner bag surface, said first major inner bag surface and said second major inner bag surface forming an article receiving pouch, said inner plastic layer being secured or welded to said outer layer;
- an intermediate insulating layer positioned between said outer layer and said inner plastic layer, said intermediate insulating layer consisting of at least one sheet of insulating foam material having (a) a first insulating foam material end portion positioned along said opening and extending within a first space between (i) said first major outer bag surface and (ii) said first major inner bag surface, (b) a second insulating foam material end portion positioned along said opening and extending within a second space between (i) said second major outer bag surface and (ii) said second major inner bag surface, each of said first insulating foam material end portion and said second insulating foam material end portion consisting of rectilinear cut outs at opposite corners thereof along said opening, (c) a middle portion formed via opposing cut outs generally centrally along opposite side edges of said intermediate insulating layer, and (d) side portions extending between each rectilinear cut out and each opposing cut out, said opposing cut outs enabling a free standing configuration whereby said intermediate insulating layer is folded centrally thereof so that said middle portion becomes the bottom, and said side portions become the walls;
- and
- a bag closure capable of at least partially closing said opening, said bag closure being selected from the group consisting of a mechanical zip-like closure, a double sided tape, a pressure closure, a taping closure, a flap with re-sealable taping means, and a flap with peel-off taping means.
