ABSTRACT:
A twist-on/twist-off resealable assembly for a can-end, such as a metal can used in the beverage industry includes a first set of knuckles formed on the can body near its top opening. A plurality of cooperating fingers on the inside of the can lid engage the knuckles so that the lid is tightened by its progressive downward motion as the lid is rotated. The lid also includes a weakened or frangible portion for forming a straw opening. A second set of knuckles are located below the top set of knuckles for engagement by fingers extending from a pilfer-proof ring. The twist-off can lid may be made from the same metal as the can body or alternatively from a transparent plastic material or a combination of metal and plastic.
