The present invention is a square bottle. In the square bottle, a body portion extending in a vertical direction is configured that a panel surface portion and a corner surface portion are disposed, a circumferential groove is formed at a center portion of the body portion in the vertical direction, a recessed portion for finger contact is disposed in a portion of the circumferential groove located on the panel surface portion, a horizontal stripe portion is provided at an upper end portion of an inner surface defining the circumferential groove, and a vertical stripe portion extending downward from the horizontal stripe portion is disposed.

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.

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 resin made container includes a spout portion to/from which a cap can be attached/detached, a shoulder portion continuous with the spout portion, a body portion continuous with the shoulder portion and a bottom portion continuous with the body portion and disposed at a lowermost part. A decompression absorption portion provided in form of a recess in the body portion includes a bulging area protruding to the outer side of the container.

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 synthetic resin delamination container formed by blow molding a preform assembly having an outer preform and an inner preform, at least either one of an inner surface of the outer preform and an outer surface of the inner preform being applied with a release agent. The delamination container has: an outer layer body including an outer mouth portion and a bottomed tubular body portion being continuous with the outer mouth portion; an inner layer body including an inner mouth portion and a volume-reducible and deformable storage portion peelably laminated on an inner surface of the body portion through a release agent layer formed by the release agent; and an outside air introduction port configured to introduce outside air between the outer layer body and the inner layer body, in which an applying amount per unit area of the release agent layer is 10 to 850 mg/m.sup.2.

A method of manufacturing a liquid container in which a liquid is stored in a storage space of the container including a mouth, a body and a bottom, the body having a lateral folding line portion being foldable when the body is flattened in a thickness direction and extending in a circumferential direction of the body, the method including a liquid blow molding step of molding a container filled full with a liquid in a storage space by placing a preform in a mold and performing liquid blow molding; and a headspace forming step of forming a headspace in which, by separating the container filled with a liquid from the container, the body is deformed in a direction in which a thickness is increased in an area of the lateral folding line portion and a volume of the storage space is increased.

A container system includes a container for holding a fluid. The container may be positioned within a box that provides structural support to the container while allowing the container system to be stacked. The container may include chamfered corners and a glug mitigation mechanism. The box may include corresponding chamfered corners and one or more access apertures for providing access to the container handle and container opening that are positioned within and below the top surface of the box.

A delamination container includes a bottle-shaped outer layer body including a mouth, a barrel and a bottom and an inner layer body releasably laminated on an inner surface of the outer layer body, the mouth being provided with an ambient air introduction hole passing through the outer layer body, in which a lower portion of the mouth is provided with a neck ring which has a notch circumferentially outside of at least a portion immediately below the ambient air introduction hole; and the notch is provided within a range of 60° on both sides of a radial reference line passing through an axial center of the ambient air introduction hole and radially extending, in a planar view of the container.
