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.

A pressurized closure assembly is provided which has a connector assembly to allow improved application of torque in limited space conditions to rotate a head away from the hub of the closure assembly.

A stopper has a head part and a stopper part. The stopper part extends from the head part to a lower end and has flanges, between the head part and the lower end, that have different diameters that increase from the head part to the lower end of the stopper part. A container has a mouth and neck and shoulder inner surfaces. The stopper part is inserted into the container through the mouth, the head part remains outside the mouth, at least one of the flanges proximate neck sealingly engages the neck inner surface, and at least one of the flanges proximate to the shoulder sealing engages the shoulder inner surface. A fluid tube is retained by the stopper. The fluid tube extends from an inlet within the container outwardly through the mouth to an outlet outside the container.

A packaging container is provided. The packaging container includes a body defining a volume. The body includes a neck extending from an opening of the body, and a base. A substrate is engageable with the neck to form a seal. The substrate defines at least one opening. A closure includes a projection engageable with the substrate. The projection defines at least one gap. In some embodiments, container systems and methods of manufacturing containers are disclosed.

A blow molded container is provided. The container includes a neck having a neck finish and a transverse rim that defines an opening. A closure is provided that is engageable with the neck such that the rim is movable relative to the neck to define one or more vents configured for passage of a gas. In some embodiments, methods of use and manufacturing containers are disclosed.

A re-closable container comprising a container body (12), a single piece metal closure and a layer of sealing compound provided on an underside of the closure. The container body and the closure have first cooperating features (14) to allow the closure to be twisted onto and off of the container body. The layer of sealing compound and a sealing surface (18) of the container body which comes into contact with the sealing compound have second cooperating features (40) which establish one or more venting passages upon rotation of the closure from a closed position. The second cooperating features comprise one or more protrusions or indents in the sealing surface and one or more corresponding indents or protrusions on the sealing compound that are radially aligned with the one or more protrusions or indents in the sealing surface when the closure is in a closed position.

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.

In one embodiment there is provided a bottle and cap package configuration designed to hold a solid substance and provide an escape path for a scent of the substance. The cap has an internal surface with a mid-section projection to cooperatively rest on an upper ledge of the bottle neck. At least one raised pad is positioned between the upper ledge of the bottle and the underneath side surface of the mid-section projection such that when the cap is positioned on the neck of the bottle, the at least one raised pad creates a ventilation gap permitting a scent of a substance contained in the well of the bottle an escape path between the upper ledge of the bottle and the underneath side surface of the mid-section projection and then around the threads to under the bottom surface edge of the cap.

A package seal for sealing engagement between a closure and a container, and including an elastomeric seal ring with a sealing portion, and a plastic projection coupled to the seal ring.

A glass container includes a base, a body extending axially from the base, and a neck finish extending from the body, the neck finish having an axial sealing surface, wherein at least a portion of the axial sealing surface extends both axially downwardly and radially outwardly. Also disclosed is a package including a glass container and a closure assembly.
