CLOSURES FOR SEALING OR PRESSURIZING PARTIALLY-FILLED BEVERAGE CONTAINERS AND METHODS RELATED THERETO

摘要

Apparatus and methods for sealing beverage containers are disclosed. In one embodiment, a beverage container cap for resealing a beverage container comprises a cap member and an inflatable member. The cap member has an interior side for sealingly coupling with an opening of a bottle. The cap member defines a pathway for selectively communicating gas through the cap member. For example, a pump can provide air through the pathway and to the interior side of the cap member. The inflatable member is configured to couple to the cap member and to expand in volume upon receiving gas from the pathway. The inflatable member includes a fluid impermeable layer and an elastic layer.

1. A beverage container cap for resealing a beverage container, comprising:
a cap member having an interior side for sealingly coupling with an opening of the beverage container, the cap member defining a pathway for selectively communicating gas through the cap member; and an inflatable member configured to couple to the cap member and to expand in volume upon receiving gas from the pathway, the inflatable member including:
a first layer for capturing gas received by the inflatable member, thereby inflating; anda second layer operatively coupled to the first layer such that the second layer expands upon the first layer inflating,wherein the first layer and second layer are unattached to each other at one or more areas to allow the second layer to expand or contract relative to the first layer.
