Abstract
A bottle plug having a body, a plug and an elastomer member. The body defines a space having an inner circumference that forms a retracted surface that projects inwardly with respect to an axis of the body to define an expansion portion. The plug includes a leg adapted to engage the retracted surface of the body. The elastomer member is configured to receive the combination of the body and plug and further includes an outer circumference which is arranged to be received by a bottle neck. Insertion of the plug into the expansion portion urges the outer circumference of the elastomer member to expand radially to thereby seal the inner circumference of the bottle neck.
Claims30
A bottle plug comprising:
- a monolithic body defining a space having an inner circumference forming a retracted surface projecting inwardly with respect to an axis of the body to define an expansion portion;
- a plug having a leg configured and dimensioned to engage the retracted surface of the body, said plug urging said expansion portion to radially expand as the plug is pushed into the body;
- and
- an elastomer member configured and dimensioned to receive the combination of the body and the plug;
- wherein an outer circumference of the elastomer member corresponding to the expansion portion of the body is configured and dimensioned to seal the inner circumference of the bottle neck when the bottle plug is inserted into the bottle neck such that insertion of the plug into the expansion portion urges the outer circumference of the elastomer member to expand radially to thereby seal the inner circumference of the bottle neck.

A bottle plug comprising:
- a body providing an annular partition having an upper surface and a lower surface, a wall axially extending from the upper for defining a compartment and a plurality of flexible walls axially extending from the lower surface for defining an expansion portion;
- a plug providing a top and a leg, the top is received in the compartment and the leg is engaged with the expansion portion for expanding;
- and
- an elastomer member adapted to receive the combination of the body and the plug;
- wherein an outer circumference of the elastomer member corresponding to the expansion portion of the body is adapted to sealably confront the inner circumference of the bottle neck by the leg engaging with the expansion portion when the bottle plug is inserted into the bottle neck.
