ABSTRACT:
A disposable and collapsible water resistant trash receptacle has a pleated sidewall comprising the side cylindrical portion of the container and a circular bottom attached to the bottom of the cylindrical portion. The upper portion of the sidewall forms an integral lid and has pairs of tie tabs so that when the receptacle is full of trash, the lid is pulled up and the pairs of tie tabs can be tied together to seal off the receptacle when full of trash. The longitudinal pleating and the type of material employed for forming the sidewall gives the receptacle sufficient rigidity so that it is freestanding when in the opened position. Additionally the pleating allows the sidewall to compress inwardly forming a compact, elongate tube for transport and sale. Further features of the basic receptacle include vertical stiffeners attached or molded into the sidewall to increase its rigidity and a transverse reinforcing strip for increasing the rigidity around the area forming the rim of the receptacle. The pleated reinforcement strip has above it a transverse crease for providing a demarcation line for folding back down the upper portion of the sidewall to provide a large mouth opening when trash is being inserted into the interior of the receptacle.
