A delamination container formed by blow molding a preform assembly includes: an outer layer body including a tubular outer mouth portion and a bottomed tubular barrel portion; an inner layer body including a tubular inner mouth portion fixed to an inner side of the outer mouth portion, and a containing portion separably laminated on an inner surface of the barrel portion and capable of volume-reduction deformation; an outside air introduction port; and a plurality of protrusions integrally provided in an upper end part of the barrel portion at intervals in a circumferential direction centering on an axial center of the outer mouth portion, the plurality of protrusions each projecting from an outer surface of the barrel portion and being recessed with respect to the inner surface of the barrel portion.

A double container has an outer layer body and an inner layer body mainly made of a polyester resin and is formed by biaxial stretch blow molding, and includes: a mouth portion; a shoulder portion, gradually increasing in diameter in a downward direction, and having an outward protruding curved shape over a length in a vertical direction in a longitudinal section; a barrel portion; and a bottom portion, wherein the mouth portion has an outside air introduction port for introducing outside air between the outer layer body and the inner layer body, and the double container includes a shoulder rib that is concave or convex as seen from outside and at least extends from an upper end of the shoulder portion to the lower end of the shoulder portion.

A container has a container body extending along a longitudinal axis from a bottom end to a top end. The container body may define an internal cavity for holding a substance. The container body may include one or more shoulders, such as a first and/or second shoulder (e.g., axial shoulder). The shoulders may be located at the top end of the container. The container may include a neck located (e.g., nesting) between the first and second axial shoulder. The neck may be configured to accept a closure device. The neck may have an inner surface that defines a passageway into the internal cavity. The container may include one or more impact absorbing regions, such as a first axial impact absorbing region. The first axial impact absorbing region may be configured to absorb an axial force applied to the first axial shoulder and/or the second axial shoulder.

Synthetic resin bottle (1) including tube-shaped body section (3) comprises eight decompression absorbing panels (8) disposed at equal intervals in body section (3) and pillar sections (9) respectively disposed between said decompression absorbing panels (8) and formed by arcuate wall surfaces (9a). Arcuate wall surfaces (9a) of pillar sections (9) in a cross section of body section (3) configure parts of one imaginary perfect circle (10). A total of circumferential lengths of arcuate wall surfaces (9a) of pillar sections (9) is 20 to 50% of a total circumferential length of perfect circle (10). Consequently, it is possible to realize the synthetic resin bottle having decompression absorbing performance in order to absorb a decrease in internal pressure, the exterior of the body section of the synthetic resin bottle being seen as a cylindrical shape whose shape is almost the same as that of a perfect circle.

A container (1) made of thermoplastic material, defining an axis (X) and having a petaloid type bottom (2), the bottom (2) comprising: —a central area (3); —a plurality of first convex surfaces (4) towards the outside of the container, which extend from the central area (3); —a plurality of feet (5), arranged alternately with the first convex surfaces (4), and projecting outwards with respect to the first convex surfaces (4); —an annular rib (6), which is coaxial to the axis (X); wherein the first convex surfaces (4) belong to the same spherical surface having the center (C) arranged on the axis (X).

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 container may comprise a tubular body having a rounded sidewall extending between a closed end defining a base portion and an opposite open end surrounded by a rim portion, and one or more sets of grooves defined within the vertical portion of the rounded sidewall. The base portion is configured to support the container in an upright orientation relative to a support surface and wherein the base portion defines a support ring having an at least substantially rounded perimeter. The rounded sidewall comprises a curved base transition region and a vertical portion extending between the perimeter of the base portion and the rim portion along a central axis. Each of the grooves comprises a length and a width, wherein the length is longer than the width. The grooves extend between the base portion and the rim portion along the length.

A delamination container formed by blow molding a preform assembly includes: an outer layer body including a tubular outer mouth portion and a bottomed tubular barrel portion; an inner layer body including a tubular inner mouth portion fixed to an inner side of the outer mouth portion, and a containing portion separably laminated on an inner surface of the barrel portion and capable of volume-reduction deformation; an outside air introduction port; and a plurality of protrusions integrally provided in an upper end part of the barrel portion at intervals in a circumferential direction centering on an axial center of the outer mouth portion, the plurality of protrusions each projecting from an outer surface of the barrel portion and being recessed with respect to the inner surface of the barrel portion.

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.
