ABSTRACT:
An apparatus (20) for opening a container (42) comprises a cord (22) looped at one end of a cylindrical member (24) and having a free end (28) that extends through the member and a transverse gripper (26). One end (36) of the cord is anchored to the wall of the cylindrical member (24), and the free end is saddled within a notch (38) formed in the gripper. The cord (22) is formed of a nylon wrap or other material that has a "rebound" characteristic, that is, wherein the cord has a diameter that reduces as the cord is stretched and rebounds as the cord is released. In use, the cord loop (44) is wrapped around the gap formed between the lid (40) and container (42). The cord (22) is manually twisted, and as the cord stretches, its diameter reduces until the cord slips into the gap. As the cord (22) is further twisted within the gap, it tends to flatten against the neck of the lid ( 40) thereby imparting an axial separating force to the lid and container. Following separation, the cord (22) rebounds to its normal shape. Adapter rings (46) and (48) establish a gap if none is provided by the structure of cover (40) and container (42).
