A square bottle comprising a mouth portion, a shoulder portion, a body portion, and a bottom portion provided to be continuous in this order from the top to the bottom in a bottle axis direction, wherein in the body portion a plurality of panel surface portions are provided to be continuous with each other with corner portions therebetween in a circumferential direction around a bottle axis and in the body portion a first peripheral groove straddling at least the corner portions in the circumferential direction is formed, and a ridge portion straddling the corner portions in the circumferential direction is formed on an inner surface defining the first peripheral groove.

Plastic containers and arrangements of reduced diameter plastic containers, including PET containers, are disclosed. In an embodiment, a plastic container arrangement is provided that includes a plurality of reduced diameter plastic (e.g., PET) containers arranged in a side-by-side configuration, wherein the ratio of a maximum outside diameter to container height is at least 0.30.

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.

A polymeric container including a finish defining an opening of the container. A shoulder of the container is between the finish and a body of the container. A base of the container is at an end of the body opposite to the shoulder. The base is configured to support the container upright. A plurality of body ribs are at the body. A shoulder rib is between the shoulder and the body. The shoulder rib has a maximum height that is about 5 times greater than a maximum depth of the shoulder rib.

Container including a body having a compartment defined therein, the body including a base portion defining a closed end, a finish portion defining an open end opposite the base portion, and a sidewall between the base portion and the finish portion. The base portion includes a support surface defining a reference plane and a contoured base recess extending inwardly from the support surface to a maximum base recess height h.sub.brmax from the reference plane. The sidewall includes a concave rib extending circumferentially around the body, wherein a center of the concave rib in side cross-section is disposed at a rib height h.sub.r from the reference plane, wherein the ratio of the maximum base recess height to the rib height h.sub.brmax:h.sub.r is between 1:3 and 1:5. The concave rib in side cross-section includes a radiused transition surface extending from the base portion to an angled inner surface, the radiused transition surface has a radius of curvature r.sub.1 of at least 0.10 inches and the angled inner surface has an angle a relative to the reference plane of between 28 degrees and 80 degrees. A method and mold assembly for making the container is also provided.

A container formed of resin includes a body portion having an approximately square cross-sectional shape, and a vertically elastically deformable cushion portion provided downwardly of a vertical center of the body portion, the cushion portion having along its entire circumference a groove which is formed progressively wider radially outwards. The container further includes an arcuate portion provided at a corner portion in a cross-sectional shape of the groove.

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning or inverting the push-up portion from the first position to a second position under the vacuum pressure.

In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.

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 polymeric container including a finish defining an opening of the container, a base, and a body. The body is between the finish and the base. The body includes a flexible panel extending entirely around the container A longitudinal axis of the container extends through an axial center of the finish, the base, the body, and the flexible panel. The flexible panel includes alternating concave portions and vertically extending columns arranged about the flexible panel. In response to a vacuum within the container resulting from filling and capping the container, the concave portions are configured to flex inward towards the longitudinal axis to become more concave, and the vertically extending columns are configured to flex outward away from the longitudinal axis of the container.
