Abstract

An expandable bag, including a body having a relatively rigid, lower portion defining a closed bottom and a generally upstanding lower sidewall having an upper rim defining an upper opening and a relatively flexible upper portion defining an upper sidewall having a lower edge coupled adjacent to the upper edge of the lower portion and having an upper rim defining a top opening. The upper portion is movable between a folded position, in which the upper sidewall is folded within the lower sidewall such that the upper rim of the upper portion and the top opening thereof is disposed generally adjacent to the upper edge of the lower portion to define an interior compartment of a certain size, and an extended position, in which the upper portion is unfolded and extended upwardly, thereby extending the height of the body and, in turn, the bag creating an interior compartment of greater size. A strap for supporting the body is secured to the upper portion generally adjacent to the upper rim thereof and a releasable coupling for releasably coupling the strap to the lower portion which serves to prevent movement of the upper portion from the folded to the extended position when so coupled and which, upon release thereof, permits extension of the upper portion.

An expandable bag comprising:

a body having a relatively rigid, lower portion defining a closed bottom and a generally upstanding lower sidewall having an upper rim defining an upper opening and a relatively flexible upper portion defining an upper sidewall having a lower edge coupled adjacent to said upper edge of said lower portion and having an upper rim defining a top opening, said upper portion being movable between a folded position, in which said upper sidewall is folded within said lower sidewall such that said upper rim of said upper portion and said top opening thereof is disposed generally adjacent to said upper edge of said lower portion, thereby defining an interior compartment of a certain size, and an extended position, in which said upper portion is unfolded and extended upwardly, thereby extending the height of said body and, in turn, said bag creating an interior compartment of a greater size;
a strap for supporting said body secured to said upper portion generally adjacent to said upper rim thereof;
and
releasable coupling means for releasably coupling said strap to said lower portion which serves to prevent movement of said upper portion from said folded to said extended position when so coupled and which, upon release thereof, permits extension of said upper portion.
