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.

Plastic container comprises a container body having a bottom portion, a sidewall portion and an upper portion, with a chamber defined therein. The bottom portion includes a support surface and a variable dynamic base portion. The sidewall portion includes a lower circumferential groove ring, an upper circumferential groove ring, and a pair of longitudinal grooves extending longitudinally therebetween to define a front sidewall segment and a rear sidewall segment. The rear sidewall segment comprises a waist groove extending circumferentially between the pair of longitudinal grooves to define an upper rear sidewall segment and a lower rear sidewall segment, wherein one of the upper rear sidewall segment or the lower rear sidewall segment includes two vacuum panels with a rigid longitudinal support therebetween.

A container having enhanced wall integrity and a rotational element is provided that includes a sidewall having polygonal cross-sectional shape and an alignment structure formed therein. The alignment structure is adapted for orienting the container with respect to a second container such that the panel sections of the containers become parallel with one another and the containers may be fully nested one within the other. The alignment structure can be recessed into the sidewall to form peaks and valleys along an inner surface of the container. The peaks include first and second faces sloping in opposite directions designed to direct corners of the first container's sidewall toward the interior valleys of the second container in order to orient the containers as they are stacked.

A composition container is described. The composition container includes an interior portion to contain a composition. A recess along a back surface of the composition container promotes the collapse of the composition container along the back surface. A number of reinforcing ribs on the front surface of the composition container promote the preservation of the front surface of the composition container during collapse of the composition container.
