Examples of the present disclosure relate to a container for storing a material for printing. The container has a generally cylindrical chamber formed by a container wall, the chamber having an opening at one end. The container has an inner structure to convey the material between an interior of the chamber and the opening during rotation of the container. The container wall has an outer surface having a planar portion to align the container upon a resting surface.

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.

The present disclosure relates to a fuel tank including a tank wall which has at least two wall sections opposite one another and a stiffening device situated between the two opposite wall sections, and a method for manufacturing such a fuel tank. According to the present disclosure, it is provided that the stiffening device includes at least one connecting strut, each end of which has a profile section, which engages with one complementary profile section each on the two opposite wall sections of the container wall in a tension-resistant manner in such a way that the connecting strut absorbs compressive forces acting on the container wall.

In one example, a method includes positioning, within a mold, a device with a movable element that defines a portion of a volume, and the volume is contained within the mold, as part of a molding process, at least partly defining a molded watercraft by introducing plastic into the mold, disposing the plastic about the movable element, and with the movable element, excluding the plastic from the portion of the volume that is defined by the movable element so as to define a recess and an undercut that are integral with the watercraft and extend lengthwise with respect to a centerline of the watercraft, and the recess and undercut are integral, and communicate, with each other.

A blow mold includes: a pair of movable molds for forming engagement grooves of a container body; and advancing/retreating mechanism units for advancing and retreating the movable molds between a standby position and a molding position. The advancing/retreating mechanism units are equipped with drive shafts to which the movable molds are fixed and which are rotatably supported with respect to a cavity mold; actuator devices which each have a linear-motion shaft capable of advancing and retreating in a direction orthogonal to the drive shaft and which are each swingably provided with respect to the cavity mold; and link members each having an end side fixed to the drive shaft outside the cavity mold and an opposite end side coupled to the linear-motion shaft.

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.
