Re-sealing Beverage Containers

A cap for re-sealing a container having an axially extending body with a laterally extending top surrounded by a rim having prescribed lateral dimensions, the top including a dispensing opening therein, the cap comprising:

• a member having an axial length between an upper end and a lower end, and an outer perimeter along lateral widths greater than the lateral dimensions of the rim;
• a recess extending axially within the member, from the lower end toward the upper end of the member, the recess being spaced laterally from the outer perimeter of the member and axially from the upper end of the member;
• and
• an internal engagement surface extending along the recess between the lower end and the upper end of the member, the internal engagement surface having a tapered configuration following a taper angle providing a sealing surface intermediate the upper and lower ends, the sealing surface having interior dimensions complementary to the prescribed lateral dimensions of the rim;
• the member including a sealing construct of a material having a combination of elasticity and hardness providing renitent characteristics such that upon engagement of the sealing surface with the rim of the container, relative movement between the cap and the container to effect axial movement between the sealing surface and the rim urging the upper end of the member axially toward the rim will effect a stick-slip advancement of the member onto the container and a concomitant audibly discernable signal indicative of the completion of a sealed relationship between the member and the rim and, consequently, an effective seal between the cap and the container.
