DEFINITION

Classification: 220/268

(under subclass 266) Device wherein the closure, or portion thereof, e.g., strip, remains attached to the receptacle

following the opening operation.

(1) Note. Devices of this type are usually intended to solve a litter or disposal problem by not allowing the opening portion to become completely unattached from the receptacle.
