AMCOR RIGID PACKAGING USA, LLC

A parison configured to be injection blow molded into a container, and a method therefor. A distal end of the parison is configured to be blown into a container base including an inner surface defining a lower end of the internal volume. The inner surface slopes downward from a sidewall to a radial center of the base such that the radial center is at a lowermost portion of the inner surface of the base, and the inner surface provides a funnel directing contents of the internal volume down to the radial center. An annular flange at a distal end of the parison is configured to be injection blow molded into a standing ring of the container. The parison is configured to form by injection blow molding the standing ring, the inner surface of the base, the container body, and the finish to be monolithic.

A closure assembly for filling a container under isolated conditions. The closure assembly includes a collar with internal threads for coupling with a finish of the container. A disc includes first coupling members for removably coupling with the collar. A liner is secured to the disc. The liner is seated on the finish of the container when the collar is coupled to the finish.

A container including an opening defined by a finish portion. A base is at an end of the container opposite to the opening. The base includes a deep base ring between a standing surface and a truncated cone at a center of the base. The truncated cone is mechanically movable a displacement distance from an as-blown position to a displaced position subsequent to hot-filling and capping of the container to reduce an internal volume of the container. In the displaced position, the truncated cone is closer to the opening than in the as-blown position.

A container blow molded from a polymeric material, which is configured to store a hot-fill product. A first wall extends from a standing ring to a diaphragm of a base. A first hinge is at a first interface between the first wall and the standing ring. A second hinge is at a second interface between a second wall and a third wall extending to a center portion. In response to a vacuum generated within the container as the hot-fill product cools subsequent to filling and capping the container, the base is configured to move inward from an as-blown configuration to an activated configuration to absorb the vacuum by flexing at the first hinge and the second hinge. In the activated configuration, the center portion, the second wall, the third wall, and the second hinge are closer to the finish than in the as blown configuration.

A container formed from a polymeric material. The container includes a finish defining an opening, a body defining an internal volume of the container, and a base. The base includes a standing ring configured to support the container upright when seated on a flat surface. An inner surface of the base defines a lower end of the internal volume. The inner surface slopes downward from a sidewall to a radial center of the base such that the radial center is a lowermost portion of the inner surface of the base and the inner surface provides a funnel directing contents of the internal volume down to the radial center of the base.

A closure for a polymeric container configured to be filled with a commodity by a hot-fill process. The closure includes an outer metallic ring and a flexible membrane. The flexible membrane is removably sealed across the ring and is configured to be drawn from an outward, pre-fill configuration to an inward, post-fill configuration in response to a vacuum created within the container during the hot-fill process. In the inward, post-fill configuration the flexible membrane is concave relate to an outer side of the closure.

A polymeric container including a finish defining an opening of the container. A body defines an internal volume for storing product therein. A base is at an end of the body opposite to the finish. The base defines a plurality of recesses spaced apart from one another about an axial center of the base.
