A cap assembly for a bottle including a cap and a fitment. The cap includes a tubular side wall extending from an upper lateral wall to an open lower end. An inner surface of the tubular side wall includes a thread. An inner surface of the upper lateral wall includes a retaining extension. The fitment includes a side wall extending from an upper lateral surface to an open lower end. The upper lateral surface of the fitment includes a central aperture having a shape that is reciprocal to a shape of the retaining extension of the cap. The fitment is selectively secured within the cap by directly engaging the central aperture of the fitment with the retaining extension of the cap. The cap and fitment of the cap assembly are secured to a bottle simultaneously. The cap is threadedly secured on the bottle, thereby securing the fitment to the bottle.

The present invention relates to compositions (compounds) which can be used as seal material in vessel caps, even under pasteurization conditions and possibly sterilization conditions. More specifically, the invention relates to such compositions that are suitable for vessel caps that can be unscrewed, such as lug screw caps and in particular Press-on/Twist-Off caps, and that result in a reduced migration of undesirable substances.

A container cap assembly includes an inner cap coupled to an inner surface and an upper end of a container neck and an outer cap maintaining the coupled state of the inner cap, thereby keeping the inside of a container sealed. The container cap assembly includes an inner cap including an outer wall portion corresponding to an inner surface of a neck of a container and a flange portion extending outward from an upper end of the outer wall portion to correspond to an upper end of the neck. An outer cap has a ceiling covering an upper portion of the inner cap and a side wall portion covering an outer circumferential surface of the neck, the ceiling and the side wall portion being integrally formed. The inner circumferential surface of the side wall portion has female threads corresponding to male threads on the outer circumferential surface of the neck.

An assembly of a closure with a container, for sealing of the container, comprises the container having an inner container surface defining a cavity opening to ambient through an opening, the closure comprising an upper portion and a lower portion, the lower portion having a lower lateral surface, the lower portion being adapted to be inserted into the opening of the container and two grooves provided on the lower lateral surface and adapted to receive two respective sealing members, the two grooves being separated by a predetermined distance, the two sealing members provided in the two respective grooves, the two sealing members being adapted to provide sealing between the lower lateral surface and the inner container surface, wherein the lower lateral surface, the inner container surface and the two auxiliary sealing members together define an annular space and a barrier sealant in the annular space.

A two-part plug assembly is disclosed for a drip-proof spout on an aseptic flexible container for flowable materials. The two-part plug assembly may include a plug and a plug insert, wherein the plug insert may include a flow inhibitor such as a baffle or valve. In a first step, the plug assembly is removably placed in a first position on a spout prior to aseptic filling. During filling, the plug assembly is removed. After filling, the plug insert assembly is replaced in a second position further down the spout wherein the plug insert fixedly engages the spout. When fixedly engaged to the spout, the plug insert remains inside the spout when the plug is removed prior to a user dispensing the flowable material. The flow inhibitor in the plug insert provides protection from leaking when the flexible container is inverted or inadvertently squeezed.

A closure device includes a stopper assembly that provides swing-top closure of a vessel, plus an adaptor so the device can be used with screw-top vessels. The stopper assembly is connected to the adaptor by two connected wires: a bail wire that connects to the stopper assembly, and a lever wire that connects to the adaptor. The inner circumference of the adaptor defines a plurality of vessel threads that engage with the threads defined by the neck of a screw-top vessel. The lever wire is readily removable from the adaptor in order to secure the protruding portions of the lever wire beneath the stop ring of the vessel.

A cap assembly for a bottle including a cap and a fitment. The cap includes a tubular side wall extending from an upper lateral wall to an open lower end. An inner surface of the tubular side wall includes a thread. An inner surface of the upper lateral wall includes a retaining extension. The fitment includes a side wall extending from an upper lateral surface to an open lower end. The upper lateral surface of the fitment includes a central aperture having a shape that is reciprocal to a shape of the retaining extension of the cap. The fitment is selectively secured within the cap by directly engaging the central aperture of the fitment with the retaining extension of the cap. The cap and fitment of the cap assembly are secured to a bottle simultaneously. The cap is threadedly secured on the bottle, thereby securing the fitment to the bottle.

In consumer-market containers for beverages or other contents under pressure, the cap provides a gas-tight seal by way of two mechanisms that work interdependently. The first is a pressure grip configured to grip the outside wall of the container. The second is twist threads, or some other second attachment structure, that urges the inside of the cap (or, typically, a cap liner disposed thereon) against the rim of the container. Release of pressurized gases when the container is first opened can be by way of release vents in the cap, or via the bottom of the cap through the twist thread area. In the latter case, particular configurations of the pressure grip are relied on to establish the gas escape path.

Disclosed is a cap arrangement for a bottle. The cap arrangement comprises a cap having a flat portion, and a hollow portion having a first end and an opposite second end. The hollow portion extends vertically from a periphery of the flat portion. One or more internal threads are arranged on the second end, of the hollow portion, away from the first end. The cap arrangement further comprises a mouth portion of the bottle, wherein the mouth portion comprises one or more complementary external threads arranged away from an opening of the mouth portion of the bottle. The one or more external threads and the one or more internal threads allow threadable engagement between the cap and the mouth portion away from the opening of the bottle.

In consumer-market containers for beverages or other contents under pressure, the cap provides a gas-tight seal by way of two mechanisms that work interdependently. The first is a pressure grip configured to grip at least one of a) the inside wall of the container and, b) the outside wall of the container. The second is twist threads, or some other second attachment structure, that urges the inside of the cap (or, typically, a cap liner disposed thereon) against the rim of the container. Release of pressurized gases when the container is first opened can be by way of release vents in the cap, or via the bottom of the cap through the twist thread area. In the latter case, particular configurations of the pressure grip are relied on to establish the gas escape path.
