A heat-set container that defines a longitudinal axis is disclosed that includes a finish and a sidewall portion extending from the finish. The container also includes a base portion extending from the sidewall portion and enclosing said sidewall portion to form a volume therein for retaining a commodity. The base portion has a plurality of contact surfaces for supporting the container. The plurality of contact surfaces are spaced away from each other about the longitudinal axis. Also, the container includes a central pushup portion disposed in the base portion and extending generally toward the finish. The central pushup portion is substantially centered on the longitudinal axis, and the central pushup portion is moveable in response to internal vacuum pressure to decrease the volume.

Pressure reduction-absorbing bottle includes: cylindrical shoulder portion; cylindrical body portion connecting to the shoulder portion lower end; and bottom portion formed in cylindrical shape with bottom and connecting to the body portion lower end. The bottom portion includes: heel portion connected to the body portion lower opening section, and bottom wall portion closing the heel portion lower opening section. The bottom wall portion includes: grounding portion, rising circumferential wall portion, movable wall portion, and recessed circumferential wall portion. The movable wall portion capable of rotating around the connection portion with the rising circumferential wall portion to move the recessed circumferential wall portion in up-and-down direction. The body portion includes straight cylindrical part connecting to the shoulder portion lower end and extending downward. The straight cylindrical part outer diameter is greater than or equal to 0.60 times the heel portion outer diameter and is smaller than the heel portion outer diameter.

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

An aseptic-fill beverage container can include a body and a base having a standing ring, a central portion, and an isolation ring that surrounds the central portion. One or more ribs can extend from the isolation ring to the standing ring such that the ribs do not extend outward the standing ring or inward to the central portion. The ribs can be s-shaped to provide rigidity and limit or prevent deformation to the base.

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

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.

A synthetic resin bottle prevents a trunk from undergoing unsightly deformation in response to reduced pressure inside the bottle and also increases flexibility in terms of container design and secures a label attachment area sufficiently. A synthetic resin bottle includes a mouth, a trunk, and a bottom, with a reduced pressure absorbing region configured to be displaced toward the inside of the bottle in response to reduced pressure inside the bottle. The trunk includes a cylindrical-shaped straight region, which has a length of not less than 100 mm in an axis direction extending along a center axis of the trunk and in which no irregularities are provided. The straight region has a weight of not less than 11 times a weight of the reduced pressure absorbing region.

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.

A plastic, hot-fillable container is provided. The container comprises a blow molded body defining a longitudinal axis. The body including a base and a neck having at least one rib disposed about at least a portion of a circumference of the neck and transverse to the axis, and at least one angled thread. The at least one rib defining a cross section having a first portion and a second angled portion. Container systems and methods of manufacturing containers are disclosed.

A plastic container for storing a product. The container includes a base formed of a plastic material and sidewalls formed of the plastic material and extending upwardly from the base, ending in an open top adapted to be closed by a cap, and with the base defining an interior volume. The container also includes a snapping frame integrally formed in the base of the plastic material. The frame has a convex base shape before activation when the pressure in the interior volume is less than or equal to a predetermined critical pressure and has a concave base shape immediately after activation when the pressure in the interior volume is greater than the predetermined critical pressure, thereby increasing the interior volume and avoiding catastrophic failure of the container. Also disclosed are a method of using the container and a process of manufacturing the container.
