发明名称 Elastic trash bag
摘要 A trash bag incorporating a mouth securing system for securing the bag to a receptacle. The invention utilizes elastic strands, or alternatively elastic bands, adhesively attached to a trash bag and extending along the mouth of the bag. The elastic strands are attached to the bag while the strands are stretched. When the strands are allowed to return to their unstretched state, the bag gathers along the strands thereby providing a stretchable region along the mouth of the bag. The bag is configured so that when the strands are unstretched, the bag mouth is smaller than the receptacle opening, but when the strands are stretched, the bag mouth is larger than the opening. The bag is placed in the receptacle, the mouth stretched and placed over the receptacle opening. The elastic strands then retract creating a restoring force that secures the bag to the receptacle.
