Claims5
A generally rectangular plastic liner bag for a receptacle, said bag comprising:
- a plastic sheet folded to form a closed bottom and sealed along each edge to define an open top having a predetermined circumference;
- a hem provided on each side at the top of said bag;
- a notch provided at each end of the said hems, and
- an elastic drawstring provided in each hem with the ends of said drawstrings being joined together in the notches at each end of the hems to form a closed loop elastic drawstring whereby said closed loop elastic drawstring has a circumference less than the circumference of the top of said bag as said bag is formed and whereby said closed loop elastic drawstring has sufficient elasticity to expand to conform to the top of the receptacle when placed over the receptacle and to retract to a circumference less than that of the receptacle when removed from the receptacle but does not retract to a degree to close the top of said bag beyond said predetermined circumference.
