A closure for a container is provided with a top portion and a skirt depending from an outer periphery of the top portion. A generally circular rim extends downwards from the lower surface of the top portion. A liner is attached to the closure between an outer surface of the rim and an inner surface of the skirt. The liner is configured to provide a fluid tight seal for containers having varied neck dimensions and/or profiles. One or more projections extend into a space formed between the lower surface of the top portion, an inner surface of the skirt, and an outer surface of the rim, with the liner enveloping and being supported in the closure by the one or more projections.

A sealing element having a substantially right-angled exterior corner is formed from a preform. The preform is formed from a strip of sealing material including a first longitudinal side surface having a projection projecting therefrom and an oppositely arranged second longitudinal side surface having a notch formed therein. The notch is aligned with the projection with respect to the longitudinal direction of the strip. A first segment of the strip is formed to a first side of the projection and a second segment of the strip is formed to a second side of the projection. The projection forms the substantially right-angled exterior corner of the sealing element following a bending of the first segment perpendicular to the second segment.

A metal cap in which a linear to be held to a cap body and separable from the cap body can be formed by a series of operations for forming the cap body and press molding the liner. The liner of the metal cap has a double-layer structure including a barrier layer on a top panel wall side and a sealing layer on the inner side of the cap body, and the barrier layer is temporarily bonded to the top panel wall with a weak adhesive at the time of molding the barrier layer and separated from the top panel wall by the natural cooling of the barrier layer after molding.

A fluid transfer hub has a first vessel closure, a second vessel closure, a gasket arranged between the first vessel closure and the second vessel closure, and a clamp at least partially surrounding the first vessel closure, the second vessel closure, and the gasket. The first vessel closure has a first body, one or more apertures extending axially through the first body, one or more first inserts extending axially through the one or more apertures, and a cast seal disposed within the first body and surrounding each first insert. The second vessel closure has a second body, one or more apertures extending axially through the second body, one or more second inserts extending axially through the one or more apertures, and a cast seal disposed within the second body and surrounding each second insert.

A package includes a container and a closure. The container includes a body formed to include a product-storage region adapted to store products therein and a brim coupled to the body and formed to include a mouth opening into the product-storage region. The closure is coupled to the brim of the container by melting a portion of the closure together with a portion of the brim to block access to the products stored in the product-storage region.

In an aspect, a cap liner comprises a sintered fluoropolymer layer; and a backing layer; wherein the sintered fluoropolymer layer is in direct physical contact with the backing layer with no intervening layer located there between. In another aspect, a method of forming the cap liner of comprises plasma etching the sintered fluoropolymer layer to form a sintered plasma etched layer; and laminating the sintered plasma etched layer and the backing layer to form the cap liner.
