A container cap which is combined with a container containing a beverage or the like, and a container combined with the container cap. The container cap is combined with a container inlet of a container body. A plurality of close contact portions in contact with the container inlet are formed, and the close contact portions form a closed curve enclosing the container inlet so as to block inflow of external air from the outside into the container body.

The present application is directed to cap assemblies and particularly, cap assembly for closing an opening in a vessel, the cap assembly including a stopper including an polymer body adapted to fit an opening of a vessel, the stopper also including a tubular portion which defines an internal passageway extending through the polymer body; and a rigid cap attached to and integral with the stopper, wherein the cap is adapted to engage the vessel and provide a sealing force between the stopper and the vessel.

A metal screw cap for a beverage bottle consisting of a dome and a cylinder having internal thread adapted to co-operate with a threaded neck of the bottle and a liner affixed to the inner surface of the screw cap, where the dome is concave and is connected with the cylinder through a top ring, where between the dome and the top ring there is a circumferential groove having the radius of the inner curvature.

A spout assembly includes a spout and a cap. The cap includes an inner ring having an outer peripheral surface provided with a first region with a first outer diameter and a second region with a second outer diameter. The spout includes a side wall having an inner peripheral surface provided with a first region having a first inner diameter and a second region having a second inner diameter. When the cap is threadably engaged with the spout, the first region of the inner ring is in close contact with the first region of the side wall of the spout throughout the circumference, and the second region of the inner ring is in close contact with the second region of the side wall of the spout throughout the circumference.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.

A method of forming a bi-injected closure, comprising the steps of: forming a cap with a top plate and a depending sidewall, in a first injection moulding phase using a first mould part, the cap formed so as to include one or more external sealing areas; changing the first mould part for a second mould part, the second mould part sealing against the or each sealing area on the cap; and forming an outer ring around the cap sidewall whilst the second mould part is sealed against the sealing area/s in a second moulding phase.

A liquid storage bottle includes a bottle main body, a nozzle having a discharge port through which a liquid stored in the bottle main body is discharged, a cap mountable on the nozzle and a sealing unit sealing the discharge port when the cap is mounted on the nozzle. The sealing unit includes an annular first rib, an annular second rib and an annular third rib. The outer peripheral surface of the first rib is inclined with respect to the axial direction of the nozzle so that a diameter decreases toward a tip portion of the first rib and the inner peripheral surface of the third rib is inclined with respect to the axial direction of the cap so that a diameter increases toward a tip portion of the third rib.

A universal capping system to implement in any bottle-coupling part to sealingly cap over bottle openings of various sizes. Such bottle-coupling part can be a douche nozzle, a liquor pour spout, an olive oil pour spout, and just a bottle closing cap. This universal capping system has a cap top and a downward-extending resilient circular 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 closure includes first and second closure portions. The first closure portion includes a polymeric top wall portion and an annular skirt portion. The skirt portion includes exterior and interior surfaces. The interior surface includes an internal thread formation for mating engagement with an external thread formation of a container and at least one rotation-inhibiting projection. The rotation-inhibiting projection is located to contact the external thread formation. The rotation-inhibiting projection is in the general shape of the letter “C” prior to engagement with the external thread formation of the container. The second closure portion includes a polymeric tamper-evident band.
