Abstract
A flexible bag having a tapered body portion with a closed bottom narrower than a top thereof. The bag has a handle portion and a folding portion coupling the body portion to the handle portion. The handle portion includes two handle halves separable to open the bag. The bag is movable from a flat position in which the holding portion is folded to an expanded unfolded position in response to the weight of objects to be carried.
Claims17
A flexible bag, comprising:
- a tapered body portion with a closed bottom narrower than a top thereof;
- a handle portion;
- and
- a folding portion coupling said body portion to said handle portion such that on folding, said body portion pivots about the bottom of said body portion to become substantially flat and on unfolding said folding portion expands outwardly to form an enlarged chamber intermediate the top and bottom of said body while a remaining lower portion of body portion pivots open about the bottom wherein the fold creases provide rigidity and resist the tendency of the body pulling in against its contents in response to the weight of those contents;
- wherein said handle portion includes two handle halves separable to open said bag to provide access to an interior thereof and movable from a flat position in which said folding portion is folded to an expanded unfolded position in response to the weight of bag contents.

- a handle portion having separable halves with each half having a handle opening and an elongated stiffening member extending across a substantial part of the opening;
- a folding portion joining said body to said handle portion, flat in a folded position and expansible with pivoting of said body portion about said bottom to have a substantially smooth continuous surface with said folding portion forming an intermediate enlarged region with fold intersections that provide rigidity and resist being pulled in against the contents in response to the weight of the contents.
