A closure can close an outlet of a vessel. The vessel outlet can comprise a tubular cavity with an interior surface. The closure can comprise a male portion comprising a distal undersized portion, a proximal oversized portion, and a taper between the undersized and oversized portion. The male portion can be inserted in the vessel outlet, undersized portion first. Interference between the inner diameter of the vessel outlet and the outer diameter of male portion can occur when the male portion is sufficiently inserted. The interference can cause the undersized portion to flare out and engage the interior surface of the tubular cavity, thereby providing a seal.

A closure device for sealing a container includes a stopper and a cap assembly. The cap assembly is configured to surround both the stopper and a neck of the container in a sealed condition and includes a ring portion and a crown portion. The ring portion contains the stopper and includes a plurality of locking tabs. The crown includes a skirt telescopically mounted over the ring and configured to radially deflect the plurality of locking tabs inwardly under an annular collar of the container when the crown is axially displaced towards the neck of the container. A method of sealing containers using the closure device is also provided.

A cap for a container comprises: a retaining ring suitable for being associated with a neck of the container, the retaining ring extending about an axis; a closure element for opening or closing an opening defined by the neck of the container; a hinge structure interposed between the closure element and the retaining ring so as to allow the closure element to be rotated relative to the retaining ring. The retaining ring and the closure element are separated by a separation line, which extends externally of the hinge structure. The hinge structure comprises at least one connection band which connects the closure element to the retaining ring, the connection band being defined inside a recess provided in a side wall of the cap, the side wall extending about said axis.

Disclosed is a child-resistant beverage lid with a perforated seal strip, wherein a user can peel away the perforated seal strip and remove the child-resistant beverage lid.

A lid for a liquid material storage container solves problems of uplift and breakage of the lid, and ensures high efficiency in attachment and detachment operations. The lid includes an upper plate portion covering a flange and a large-diameter opening of a storage cylinder; a plug portion extending downward from a central region of the upper plate portion and plugging the large-diameter opening of the storage cylinder; a pair of first lateral portions coming into contact with lateral surfaces of a pair of short sides of the flange when the lid is closed; a pair of claw portions extending from the pair of first lateral portions toward the plug portion and coming into contact with lower surfaces of the pair of short sides of the flange when the lid is closed; and a push-up operating portion formed in at least one of the pair of first lateral portions.

A flip-top closure includes first and second polymeric closure portions. The first closure portion includes a top wall portion, a sealing mechanism and an annular skirt portion. The second closure portion includes a tamper-evident band. The closure portions are attached by a line of weakness. The closure portions are further attached via a hinge. The hinge includes a locking tab, a flexible tab and linking segments. The locking tab extends further outwardly from a center of the closure in a closed position than the flexible tab and the linking segments. During the opening of the flip-top closure, the locking tab moves and passes the flexible tab such that the flip-top closure locks in a fully open position.

A lid assembly for a food container is described that may be used to store and transport food items. The container defines an interior to store a food product. The lid assembly includes a lid and a stopper that is sized to close an opening of the container. A biasing member urges the lid to an open position when the lid is unlocked or unlatched.

A tamper evident seal structure for a vial septum or other cover having a housing including a sidewall terminating in oppositely disposed open and closed ends. A retainer is fixedly disposed within the housing and structured for retaining engagement with a portion of a vial, substantially adjacent the vial cover. The housing also includes a pressure member disposed within an interior thereof in attached, relation to the closed-end. The pressure member and the retainer are cooperatively disposed and structured to respectively exert pressure on the vial cover concurrent to retaining engagement with the vial. Tamper evident capabilities are at least partially defined by a detachment of a removable sidewall section from a remainder of said sidewall.
