A polymeric container including an upper portion defining an opening to an interior volume of the container. A base is movable to accommodate vacuum forces generated within the container, thereby decreasing the volume of the container. A substantially cylindrical sidewall extends between the upper portion and the base. A rigid, central pushup portion of the base is at an axial center of the base. A central longitudinal axis of the container extends through a center of the central pushup portion. A flexible diaphragm of the base extends outward from the central pushup portion.

The present invention relates to oxaloacetic acid preparations and the use of hygroscopic components to prevent decomposition of the oxaloacetic acid. These compounds can then be made into sublingual lozenges and buccal lozenges to serve as nutritional supplements, medical foods or drugs. These compounds can also be used in the manufacture of oxaloacetic acid preparations in transdermal patches, inhalation preparations and anal or vaginal suppositories. Also provided are simple inexpensive tests to monitor the decomposition of oxaloacetic acid in compositions.

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 method is described for shaping the bottom of hot-filled containers, in which the bottoms of the containers are forced inwardly from a state bulged outwardly, in particular as they cool down. Complex mechanisms for forcing the bottom inwardly are dispensable for the reason that the bottoms are forced inwardly by at least one fluid jet and/or fluid pressure wave. In addition, shaping the bottom can advantageously be carried out in a production region immediately downstream of a closer.

A blow-molded container including a finish and a base portion. The finish defines an opening at a first end of the container that provides access to an internal volume defined by the container. The base portion is at a second end of the container opposite to the first end. The base portion includes a fold proximate to a sidewall of the container.

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 mold for blow molding a container from a preform, the container including a wall portion and a base including a high standing ring and a central outwardly-inclined invertible diaphragm, the mold including sidewalls forming a counter print of the wall portion of the container (1) and a mold base (36) having an upper surface (37) defining a counter print of the container base, wherein the upper surface (37) includes: an annular peripheral face (43) corresponding to an annular support flange of the container base; a frusto-conical outer face (44) corresponding to an inner portion (11) of the high standing ring, the outer face (44) protruding upwardly with a draft angle (A2) from an inner edge of the peripheral annular face (43) up to a sharp apex (45), and a frusto-conical downwardly inclined inner face (46) corresponding to the invertible diaphragm.

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 shoulder portion and a bottom portion continuous with body portion and disposed at a lowermost portion of the bottle. Bottom portion includes a bottom face which comes into contact with a disposing surface and a sloped portion extending with a slope from the bottom face to the body portion. At least a portion of a vertical cross sectional shape of the sloped portion is a linear portion or a curved portion which protrudes to the inner side of the container. An angle formed between the linear portion of sloped portion and disposing surface or an angle formed between a straight line interconnecting an upper end and a lower end of the curved portion and disposing surface ranges from 15 to 70 degrees.

A container is configured so that a bottom section has a ground contact section provided to the outer periphery of a body section, and a raised bottom section provided inside the ground contact section and deformed in accordance with a change in inner pressure; the raised bottom section is provided with an upper surface section provided at the center, and a connection section which connects the upper surface section and the ground contact section; the connection section is formed so that, when the inner pressure is normal pressure, the upper surface section-side end of the connection section is positioned closer to a neck section than the ground contact section-side end of the connection section; and at least the connection section of the bottom section is provided with a reinforcement section which extends in the radial direction of the bottom section and reinforces the bottom section.

A base for a plastic container including an outer support portion; a structured formation ring including a plurality of sequential formations; an inner inversion portion disposed radially inwardly of the structured formation ring; and a central portion. In an embodiment, the sequential formations are disposed in a substantially ring-like configuration and at least the inner inversion portion is configured to flex in response to internal vacuum forces associated with said container.
