Abstract

An inflatable beverage container insulating jacket, more particularly, a jacket which when collapsed conveniently stores in a credit-card sized pouch for carrying in a wallet or purse. The insulating jacket includes a generally cylindrical inflatable wall and a base unitarily attached to the wall, which when inflated forms the receiving space for the container. Both the wall and the base are made up of an interior partition and an exterior partition peripherally attached to one another, thus defining an interiorly disposed chamber for rigid inflation of the wall. An inflation valve having a minimal dimension, such as a resealable compression-type zipperless closure, is attached to the wall along a top edge of the wall, the valve permitting rigid inflation of the unitary base and wall by virtue of a plurality of interconnected air cells. Each air cell is defined in the wall and base by a plurality of tacking welds. When deflated, the jacket can be collapsed to credit-card sized dimensions and carried in an approximately credit-card sized pouch by virtue of its planar dimensions and minimally dimensioned valve. A method of construction which accommodates the objective of maintaining a very thin profile and planar dimensions of the jacket when collapsed is also described.

Dependent claims

An inflatable insulating jacket, comprising:

a generally cylindrical inflatable wall portion, defining an interior for receiving a container and having a bottom edge and a top edge, said wall portion being comprised of an interior partition and an exterior partition peripherally attached to one another by a pneumatically tight seal thereby defining an interiorly disposed chamber permitting inflation of said wall portion;
a base having at least two bridges each integrally attached to said wall portion along opposing portions of said bottom edge, said base comprising an interior partition and an exterior partition peripherally attached to one another by a pneumatically tight seal and defining an interiorly disposed chamber for inflating said base in pneumatic communication through each said bridge with said interiorly disposed chamber of said wall portion, said base further defining a pair of opposingly positioned tabs attached to said bottom edge of said wall portion;
a plurality of interconnected air cells defined in said wall portion and said base by a plurality of tacking welds attaching the interior partition to the exterior partition;
and
an inflation valve attached along said top edge in operable communication with said interiorly disposed chamber of said wall portion;
whereby said base and said wall portion defines a unitary construction for receiving a container and said valve permits rigid inflation of said unitary construction by virtue of said plurality of interconnected air cells.
