Abstract

A collapsible disposable bag which is self supporting in full open vertical position ready for use. The bag has a framework sandwiched between outer and inner layers of plastic material. The framework employs a first plurality of elongated flexible vertical members disposed side by side to define a cylinder. Draw string means interconnects the top ends of all of said members. A second plurality (equal to one half of the first plurality) of horizontally elongated flexible members are pivotally secured together at a common center and extend radially outward. Each end of each horizontal member is secured to the bottom end of a corresponding vertical member. The vertical members define a vertical cylindrical wall and the horizontal members define a horizontal base. The outer and inner layers seal off the openings between adjacent members whereby the bag is formed.

Claims

1. A collapsible, disposable, self supporting bag comprising:

a plurality of flexible vertically elongated members disposed side by side to define a cylinder;

draw string means interconnecting the top ends of all of said members; and

a second plurality of horizontally elongated flexible members secured to each other at a common center and extending radially outward, there being twice as many vertically elongated members as horizontally elongated members, each end of each horizontally elongated member being secured to the bottom end of a corresponding vertically elongated member.

2. The bag of claim 1 further including a flexible outer layer of plastic material secured to the outer surface of said members and open at the top.

3. The bag of claim 2 further including a flexible inner layer of plastic material secured to the inner surface of said members and open at the top.

4. The bag of claim 3 wherein the horizontally elongated members are pivotally secured to each other at their common center.
