Abstract: A polymeric container including an upper portion defining an opening to an interior volume of the container. A base is movable to accommodate vacuum forces generated within the container, thereby decreasing the volume of the container. A substantially cylindrical sidewall extends between the upper portion and the base. A rigid, central pushup portion of the base is at an axial center of the base. A central longitudinal axis of the container extends through a center of the central pushup portion. A flexible diaphragm of the base extends outward from the central pushup portion.

Abstract: A polymeric container including a base, a body, a finish, finish threads, and a tamper lip. The body extends from the base. The finish defines an opening through which a product can pass into, and out of, an internal volume of the container defined at least in part by the body. The finish threads are at an outer surface of the finish, and are configured to cooperate with closure threads of a closure to secure the closure to the finish. The tamper lip extends from the outer surface of the finish, and is configured to replace the support flange during handling, and to cooperate with a tamper tab of the closure. The closure diameter is about the same as the neck diameter.

Abstract: A controlled release container including a base. The base has a flexible diaphragm movable between a relaxed position and a depressed position. In the depressed position the flexible diaphragm reduces an interior volume of the container to dispense a dosage amount of material stored within the container. The dosage amount directly corresponds to an internal volume of the container displaced by moving the flexible diaphragm to the depressed position.

Abstract: A container defining a longitudinal axis and a transverse direction that is transverse with respect to the longitudinal axis. The container includes a finish and a sidewall portion extending from the finish. A plurality of ribs are defined by the sidewall. A base portion extends from the sidewall portion and encloses the sidewall portion to form a volume therein for retaining a commodity. The base portion has a contact surface for supporting the container. A plurality of straps extend radially along the base portion away from the longitudinal axis in the transverse direction, each one of the straps defines a strap surface that is closer to the finish than the contact surface. The plurality of ribs and the base portion are configured to place the container in a state of hydraulic charge-up when top load is applied to the container after the container is filled.

Abstract: A container including an opening defined by a finish portion, and a base at an end of the container opposite to the opening. The base includes a standing ring extending inward from a heal to a center pushup portion. The center pushup portion includes an pushup ring surrounding an inversion portion. In an as-blown position the inversion portion extends outward and beyond the pushup ring such that the inversion portion is further from the opening than the pushup ring. In a final position the inversion portion is inverted relative to the as-blown position such that the inversion portion extends inward so as to be closer to the opening than the pushup ring. The inversion portion is mechanically moved from the as-blown position to the filled position with an inversion device after the container has been filled to reduce vacuum or increase pressure within the container.

Abstract: A container including a finish defining an opening at a first end of the container that provides access to an internal volume defined by the container. A base portion of the container includes a diaphragm that is concave relative to an exterior of the container. The diaphragm extends from a standing surface of the container to a center push-up portion of the base portion. The standing surface is at a second end of the container opposite to the first end. The diagram is configured to move from an as-blown first configuration to a second configuration in which the diaphragm is closer to the first end as compared to the first configuration in order to reduce residual vacuum within the container. The diaphragm is generally hemispherical in cross-section when in the second configuration.

Abstract: A closure system for a container. The system includes a closure configured to couple with a finish of the container to close an opening of the container defined by the finish. A tamper ring is removably attached to the closure. Upon removing the closure from cooperation with the finish of the container, the tamper ring detaches from the closure and remains on a neck of the container.

Abstract: A container includes a finish, a shoulder portion, a body, and a base portion. The finish defines an opening. The shoulder portion extends from the finish. The body extends from the shoulder portion and defines a chamber. The base portion extends at an end of the body opposite to the shoulder portion and is moveable from an as-blown position to an expanded position and from the expanded position to a retracted position. The base portion includes a standing ring, a pivot area, and a central area. The pivot area is disposed between the standing ring and the central area. The pivot area is configured to flex and move the central area along the longitudinal axis when the base portion moves from the as-blown position to the expanded position, and from the expanded position to a retracted position.

Abstract: A container including at least one sidewall. The sidewall includes first and second vacuum panels, and a plurality of first and second ribs. The first and second vacuum panels are recessed beneath an outer surface of the sidewall. The second vacuum panel is spaced apart from, and vertically aligned with, the first vacuum panel. The plurality of first ribs protrude outward from the first vacuum panel. The plurality of second ribs protrude outward from the second vacuum panel.

Abstract: A mold system for forming a container having a longitudinal axis and a transverse direction that extends transverse to the longitudinal axis. The mold system includes a sidewall system for molding the sidewall portion of the container. The mold system also includes a base system for molding the base portion of the container. The base system is operable for forming the entire base portion of the container including a central pushup portion, a contact surface for supporting the container, and at least one strap extending along the base portion in the transverse direction. The strap defines a strap surface that is spaced offset in a direction parallel to the longitudinal axis from the contact surface. The strap surface extends in the transverse direction to be adjacent the sidewall portion such that the at least one strap surface is visible from a side of the container.

Abstract: A child resistant closure for use on a container that include an inner closure member having a threaded portion and an outer closure member coupled to the inner closure member for axial translation there between. A series of engagement features extend between the inner and outer closure to permit selective engagement of the outer closure to the inner closure to effect removal of the child resistant closure. The outer closure includes a diaphragm member disposed along the distal end surface of the outer closure. The diaphragm member is inwardly directed and contacts the inner closure member thereby biasing the outer closure member into an operationally disengaged position.

Abstract: A blow molding machine assembly configured to be mounted to a blow molding machine to move a mold base configured to form a container base. The blow molding machine assembly includes an over-stroke cylinder and a counter-stretch rod. The over-stroke cylinder is configured to move the mold base between an extended base position and a retracted base position. The counter-stretch rod is movable between a retracted rod position in which the counter-stretch rod does not extend out from within the mold base, and an extended rod position in which the counter-stretch rod extends out from within the mold base.

Each strap of a plurality of straps is arranged between neighboring feet. Each one of a plurality of fillet areas is arranged between one of the plurality of feet and straps on opposite sides thereof.
