A closure 40 for a container body includes a liner 46 which incorporates a hydrogen generating device comprising a hydride which generates hydrogen on contact with moisture. The liner may be an interference fit within the body 42. The liner 46 and other liners described may include control means for controlling passage of moisture to the hydrogen generating means and/or sealing means for sealing the closure to a container. In use, with the closure secured to a container, water vapor passes into liner 46 and contacts the hydride which generates hydrogen. A reaction between hydrogen and oxygen which has passed into the container takes place, catalysed by a catalyst, and water is produced. Thus, oxygen is scavenged.

This assembly includes a tubular body and a breathable insert configured to be attached inside the tubular body to define a chamber for an active material. The tubular body includes a transverse wall and a lateral wall, and the breathable insert includes a base wall and a side wall having an open end on an opposite side from the base wall. The chamber is delimited by a bottom part of the tubular body and is closed by the breathable insert having its open end turned toward the transverse wall. The side wall of the breathable insert includes a mechanical holding portion configured to cooperate by surface interference with a corresponding mechanical holding portion of the tubular body. In an anchored configuration, a continuous peripheral seal is formed between the breathable insert and the tubular body.

A closure device for a container to provide a combined protection of inert gas and oxygen scavenger methods. The closure device comprises a body, a fastening member, one or more plurality of protrusions, a blister, a hollow shaft, and a seal member. The closure device is removably coupled to an open end of the container through a fastening assembly. The fastening assembly includes at least one of friction fit, a snap fit, a screw fit, or any of a variety of fastening mechanisms. The closure device provides a combined protection of inert gas and oxygen scavenger methods. This is beneficial because it prevents nutritional and organoleptic degradation processes of wine through oxidation while aids to preserve the fruitier and fresher aromas and flavors of the wine. The closure device is designed to fit snugly over the neck of the bottle and create an airtight seal.

A screw cap (14, 502) configured to be removably attachable to a bottle (12) includes a base (40) and an annular skirt (42, 508) extending downwardly therefrom. One or more threads (32) extend radially inwardly from an interior surface of the skirt (42, 508). A retention feature (509) extends radially inwardly from the interior surface of the skirt (42, 508). The retention feature (509) is configured to produce at least one of an audible response or a tactile response when the cap (14, 502) is rotated with respect to a bottle (12).

A beverage sealing cap that absorbs oxygen keeps a bottled beverage, such as a bottle of wine, fresh after opening and re-sealing. The beverage sealing cap is made with a thermoplastic elastomer stopper containing an oxygen absorber. When inserted into an opened beverage bottle, the stopper seals the bottle to prevent ingress of air, while the oxygen absorber removes the oxygen present in the air inside the bottle. As a result, the contents of the bottle are preserved in a fresh state, avoiding degradation of flavor and waste due to spoilage.

A tamper-evident closure including an outer cap with a sidewall and a top wall; an inner cap with a sidewall and a top wall, coaxially nested in the outer cap; a safety strip arranged between the outer cap and the inner cap to block at least one degree of freedom of relative movement of the outer and inner caps, wherein the safety strip is integrally made with one cap and connected thereto by a frangible structure; a first engagement mechanism between the safety strip and the other cap, to drive the caps in unison in a screwing direction to mount the closure on the container; a second engagement mechanism between the caps, to drive the caps in unison in an unscrewing direction (R.sub.2) to remove the closure from the container, wherein the second engagement mechanism is activatable when the safety strip has been removed.

A sealing cap, which engages a neck of a bottle, including a top wall from which extend a sidewall and a sealing skirt. The sidewall includes a cap thread to be screwed onto a neck thread of the neck of the bottle around a screwing axis. The sealing skirt includes an inclined sealing surface to be pressed against a corresponding surface of the neck on an opposite side from the surface including the neck thread, upon screwing the cap thread onto the neck thread. The inclined sealing surface is formed by a wall of the sealing skirt surrounding a cavity. An inclination angle between the inclined sealing surface and the screwing axis is between 7 and 25. An axial length of the cap thread, taken parallel to the screwing axis, is higher than or equal to 1.5 times a pitch of the cap thread.
