A foldable cup provided with a reinforcing structure includes: a cup body, a shape-fixing ring nested on the opening of the cup body, and a cup cap fitted to the shape-fixing ring. When the cup body is deformed due to the effect of force, the side wall of the cup body is prevented from experiencing a large twist due to the deformation of the opening of the cup, thereby effectively alleviating the disadvantages of an existing foldable cup: the existing foldable cup easily topples and falls due to the deformation of the opening of the cup, causing a liquid in the cup to be splashed. Further, when the side wall of the cup body is extruded, the liquid in the cup does not flow out from the joint position between the shape-fixing ring and the cup cap, thereby improving the practicability of the foldable cup.

A preform for a stretch-blow-molded plastic container includes an elongated, tube-like preform body. An outer wall and an inner wall delimit a bottom thickness (b). An outer wall and an inner wall delimit a wall thickness (w). An inner surface and an outer surface (E1) curved in three-dimensionally convex manners are spaced apart such that a distance from their respective apex (S, S′) to the preform body continuously increases. Extensions of the outer wall of the preform bottom along the outer three-dimensionally curved surface (E1), and of the inner wall of the preform bottom along the inner three-dimensionally curved surface (E2) are configured to be interrupted by set-backs area outside of their respective apex (S, S′) thereof.

Provided is a resin container for a water server, the container including an upper surface portion where a liquid inlet and outlet portion is formed, a side surface portion connected to the upper surface portion, and a bottom surface portion disposed on a side opposite to the upper surface portion and connected to the side surface portion. A round corner surface portion is formed to the side surface portion such that the container has a polygonal shape with round corners when the container is viewed from an upper surface portion side. A wall thickness of a shoulder portion of the upper surface portion which is defined between the round corner surface portion of the side surface portion and the inlet and outlet portion is larger than a wall thickness of a portion of the upper surface portion which is adjacent to the shoulder portion.

In an embodiment, the invention comprises a container apparatus with a lateral stability rail system. At least one rail extends within the lid portion and at least one track extends through the base portion. The rail terminates in a tooth and the track terminates in a pocket. When the container is in a hingedly closed position, the at least one rail nests within the at least one track and the at least one tooth nests within the at least one pocket.

The present invention relates to a top chime for a beverage keg. The top chime is configured to be readily removable from the keg, for example to enable recycling of the top chime separately to the keg. The top chime comprises a mounting portion for mounting the top chime to a keg in use, and a mounting element separate to the top chime that is configured to be assembled together with the top chime after the top chime has been moved into a mounted position with respect to the keg to thereby secure the top chime with respect to the keg. The top chime is provided with a mounting element that is configured to engage the mounting portion to thereby secure the top chime with respect to the keg. The mounting element is configured to be assembled together with the top chime by moving the mounting element in a radially inward direction with respect to a longitudinal axis of the top chime.

The inventive technology includes a novel container dome profile and manufacturing process for improving container and bottle deformation failure resistance and extending material displacement modes through an initial deformation panel coordinated with complimentary geometric paneling and buttressing structures configured to initiate a controlled sequential dome profile deformation mode. Dome reversal, dome growth, and dome drop resistance characteristics are improved with a shallower profile formation depth, reducing pulldown, and lowering material consumption, resulting in lower overall container/bottle weight. Novel geometric contoured shapes enhance container resistance performance, supporting use of softer alloys or lower temper and yield strength to benefit post-processing efficiency and forming processes improvements while being configured to initiate controlled sequential dome profile deformation.

A drink cup includes a body formed to include an interior region providing a fluid-holding reservoir and a brim. The brim is coupled to the body to form an opening into the interior region. The body includes a floor and a side wall that extends away from the floor. The drink cup further includes a body-strengthening system coupled to the body.
