The base includes an outside wall, a chime connecting the outside wall to an annular contact ring, an inside wall extending upward from the contact ring to a hinge, and a diaphragm connected to the hinge. The diaphragm can move between first and second positions in response to pressure change within the container. The diaphragm includes a central region and a flexible wall having a curved profile in cross section. The flexible wall curves downward from the hinge to the central region. In some embodiments, the flexible wall is asymmetric and includes a first portion having a curved profile and a second portion having a linear profile. A container wall structure is also disclosed.

A plastics material container for holding liquids, in particular beverages, having a bottom section, a main body adjoining the bottom section that forms a holding volume that extends in a longitudinal direction of the plastics material container, a shoulder region adjoining the main body in the longitudinal direction, in which a cross-section in the longitudinal direction is reduced and with a mouth region which adjoins the shoulder region in the longitudinal direction, in which a mouth is formed, via which a liquid can be supplied to the container, wherein the shoulder region and the mouth region are arranged in an upper section of the plastics material container in relation to the longitudinal direction. The container has a deformation section in the upper section and in the longitudinal direction below the mouth section, in which deformation section the plastics material container is elastically deformable with respect to its longitudinal direction.

A synthetic resin bottle, which has a pressure reduction absorbing performance and which exhibits a cylindrical shape in which the appearance of the body section to which the label is attached is similar to a perfect circle, is provided. A synthetic resin bottle 1 having cylindrical body section 3 has four pressure reduction absorbing panels 8 arranged at equal intervals in body section 3, and column portions 9 each having an arc-shaped wall surface 9a arranged between pressure reduction absorbing panels 8. Arc-shaped wall surface 9a of column portion 9 in a cross section of body section 3 constitutes a part of a virtual single true circle 10. Total circumferential length of arc-shaped wall surfaces 9a of column portions 9 is 55% to 75% of entire circumferential length of true circle 10.

A beverage container includes a base, a sidewall extending from and integrally formed with the base, and an upper region extending from the sidewall and defining an upper opening. The beverage container includes a longitudinal axis extending in a direction from the base to the upper opening. The beverage container further includes a continuous channel formed in and extending continuously around a circumference of the sidewall, wherein the continuous channel includes peaks and troughs connected by diagonal regions. The continuous channel is configured to resist paneling and elongation of the beverage container. The beverage container further includes a central channel formed in and extending continuously around a circumference of the sidewall at a central portion of the sidewall, wherein the central channel is configured to resist paneling of the beverage container.

A bottle is provided for storing an associated fluid product when filled. The bottle includes a first wall having an opening therein that is selectively opened and closed to allow the associated fluid product to be dispensed therethrough or stored in the bottle, respectively. A second wall is spaced from the first wall, and a third wall extending between the first and second walls. A compliant pleat extends along substantially an entirety of the first wall, second wall, and third wall and divides the bottle into first and second portions. The compliant pleat allows the first and second portions to move toward one another in response to a predetermined force and thereby increase pressure in the closed bottle.

An asymmetric pressurized plastic container includes a bottom, a shoulder portion and a finish portion that is unitary with an upper end of the shoulder portion. A generally cylindrical bumper portion having a first longitudinal axis is provided at a lower end of the shoulder portion. A generally cylindrical main body portion having a second longitudinal axis is positioned beneath the bumper portion and has at least a first sidewall feature defined therein. The first and second longitudinal axes are offset so as to compensate for any lateral deflection of the container that may occur as a result of pressurization acting upon the first sidewall feature. In addition, the main body portion may include a second sidewall feature to provide additional compensation against lateral deflection of the container causes a result of pressurization acting upon the first sidewall feature.

A hot-fillable plastic container includes a base and a body extending upward from the base. The includes a deformable cylindrical sidewall portion defining a central vertical axis, wherein the deformable cylindrical sidewall portion comprises at least two vertical pillars arranged along the body circumference. Each vertical pillar is joined to the next vertical pillar by a generally concave deformable sidewall panel having a concave arc-shaped transverse cross section of curvature radius. The curvature radii of the vertical pillars are smaller than the curvature radii of the generally concave deformable panels, and each transition between a vertical pillar and a generally concave deformable panel is smooth without any convex portion. The large curvature radius of each generally concave deformable panel allows an inward deformation of each panel, and each pillar is slightly pushed outward and is slightly deformed with a small reduction of its curvature radius, under the vacuum created inside the container by the volume reduction of a hot-filled product during cooling.

The present disclosure describes a hot-fill container for use with a hot-filling process. The container includes vacuum absorption sections that resist partial collapse and uncontrolled deformation of the container's walls during the hot-filling process. The vacuum absorption sections are asymmetrically-formed and include respective edge portions and panel portions configured to deform and pivot about a linear part of the edge portions when a vacuum is created inside the container. The edge portions have a curvilinear part that is adapted to comfortably receive and engage a user's fingers during use of the container, making the container more user friendly. The vacuum absorption sections are arranged about the container's central longitudinal axis such that their respective panel portions substantially form the sides of a polygon when viewed in top plan view. The polygon appears to be inscribed within an otherwise circular container periphery.

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 multi-layer beverage container made is disclosed. An outer layer encloses an inner layer that is configured to shrink or flex to accommodate volume changes of a beverage inside the beverage container caused by a change in temperature of the beverage in the sealed beverage container. The inner layer is not attached to the outer layer through the majority of the beverage container, with attachment zones being located at selected areas of the outer layer. There is a space between the inner layer and the outer layer. A gas introduction system is provided in the space to maintain a desired gas pressure in the space. The set gas pressure allows outer layer to be designed without the need to resist deformation caused by reduced pressure due to changing volumes of the beverage.
