A plastic container has a mouth portion, a main body, and a base portion which adjoins the main body. The base portion has a central region as well as a diaphragm which runs in a circumferential direction and extends from the central region to the main body. The central region is pivotable relative to the main body between at least two positions which differ with regard to an internal volume of the container. The wall has at least one and preferably at least two circumferential grooves and are spaced apart from one another. The central region has a projection extending in the direction of the interior of the plastic container, and at least one web extending at least in part in a radial direction in the circumferential wall.

A plastic, hot-fillable container is provided. The container comprises a blow molded body including a neck and a base having a center portion and a plurality of spaced apart radial segments. At least a portion of each segment is tapered from an outer side to an inner side thereof. Container systems and methods of manufacturing containers are disclosed.

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 blow molded container is provided. The container includes a neck including a sealing surface and a neck finish. The sealing surface defines at least one vent. In some embodiments, methods of manufacturing containers are disclosed.

Hot-fillable plastic bottle including a finished portion, a body portion with at least one circumferential rib configured to resist radial distortion, and a base portion. The base portion comprises a base sidewall, a bottom support surface extending radially inward from the base sidewall and defining a reference plane, an inner support wall extending upwardly from the bottom support surface, and a diaphragm extending radially inward from the inner support wall. The diaphragm comprises an inner wall having an arcuate shape with a radius r1 and a central conical structure, where the diaphragm is in an initial as-formed position with the conical structure above the reference place. The diaphragm is configured to move from an initial as-formed position toward a second position when an internal pressure relative an external pressure exceeds a threshold value.

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 having an upper container part having an upper container part outer profile, the upper container part having a height; a plurality of sidewalls that extend radially about at least a portion of the container, the upper container part extending from a radially inner end of the plurality of sidewalls; a container base has a central female coupling formed therein, the central female coupling having a receiving profile that is complementary to the upper container part outer profile and a depth that is greater than the height of the upper container part; and a body extending between the a radially outer end of the plurality of sidewalls and the container base. The plurality of sidewalls and the container base are longitudinally spaced apart from each other, substantially parallel to each other, and at least partially overlap radially.

Hot-fillable plastic bottle including a finished portion, a body portion with at least one circumferential rib configured to resist radial distortion, and a base portion. The base portion comprises a base sidewall, a bottom support surface extending radially inward from the base sidewall and defining a reference plane, an inner support wall extending upwardly from the bottom support surface, and a diaphragm extending radially inward from the inner support wall. The diaphragm comprises an inner wall having an arcuate shape with a radius r1 and a central conical structure, where the diaphragm is in an initial as-formed position with the conical structure above the reference place. The diaphragm is configured to move from an initial as-formed position toward a second position when an internal pressure relative an external pressure exceeds a threshold value.

There are provided a bactericide diffusion apparatus and a bactericide diffusion method that have excellent design and make it possible to stably diffuse a bactericide. A bactericide diffusion apparatus includes: a bactericide containing chlorine dioxide; a first container housing the bactericide and having a first opening; and a second container housing the first container, having a second opening and being made of a ceramic. The first container includes a first portion defining the first opening, a second portion located below the first portion and having a diameter larger than that of the first opening, and a third portion located below the second portion and having a diameter larger than that of the second portion. The second container includes a main body portion housing the first container and having the second opening, and a lid portion fitted to the second opening. The lid portion has a hole for diffusing chlorine dioxide.

A beverage container that includes a base, a cylindrical 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 around a circumference of the sidewall. The continuous channel is sinusoidal such that the continuous channel forms peaks and troughs. A height of the continuous channel as measured in a direction of the longitudinal axis from a peak to a trough is about 30% to 80% of a height of the sidewall, such that the continuous channels resists elongation of the beverage container in a direction of the longitudinal axis.
