Abstract
A beverage container closure includes a cap and a monolithic cap liner having concentric first and second seal rings coupled to the cap. The concentric first and second seal rings are adapted to mate with an annular rim provided on the neck of a beverage container and formed to include an open mouth to allow liquids to flow through the neck into and out of the beverage container. At least one of the seal rings is splayed relative to the annular rim during installation of the cap on the container neck to form a seal between the cap and the beverage container.
Claims43
A beverage container closure comprising
- a cap including a top wall and an annular skirt depending from the top wall and
- a monolithic cap liner including a mount coupled to the top wall, a first seal ring arranged to depend from the mount, and a second seal ring arranged to depend from the mount and surround the first seal ring.
A beverage container closure comprising
- a cap formed to include an interior region adapted to receive a neck of a beverage container therein and
- a monolithic cap liner located in the interior region and adhered to the cap, the monolithic cap liner includes a round disk having a top surface adhered to the cap and an opposite bottom surface, a first seal ring arranged to depend from the bottom surface of the round disk, and a second seal ring arranged to depend from the bottom surface of the round disk and surround the first seal ring.
A beverage container closure comprising
- a cap formed to include an interior region adapted to receive a neck of a beverage container therein and
- a monolithic cap liner located in the interior region, the cap liner includes a disk adhered to the cap, a first seal ring, and a second seal ring arranged to surround the first seal ring, the first seal ring having an annular base appended to the disk and an annular crest arranged to lie at a first distance from the disk to provide the first seal ring with a first profile height, the second seal ring having an annular base appended to the disk and an annular crest arranged to lie at a lesser second distance from the disk to provide the second seal ring with a second profile height that is less than the first profile height associated with the first seal ring.
A method of establishing a sealed connection between a cap and a neck of a beverage container to close an open mouth formed in the neck, the method including
- moving first and second seal rings included in a cap liner toward an annular rim formed in a beverage container neck to define an open mouth and
- moving a cap carrying the cap liner relative to the beverage container to splay at least one of the first and second seal rings relative to the annular rim upon contact of the first and second seal rings with the annular rim to form a seal between the cap and the beverage container.
