According to the inventive method for shaping hollow bodies made of thermoplastic material which comprise at least one gas pocket (3) having a wall (6), said wall (6) of the gas pocket(s) (3) is externally subjected to the action of pressure in all-over manner, and the hollow body to be shaped is heated when the wall (6) of the gas pocket(s) (3) is being externally subjected to the action of pressure. A device is Configured for carrying out the inventive method. The inventive method or device prevent an undesired deformation or a bursting open of the wall of the gas pocket(s) when heating the hollow body.

A transport box has a one-piece container, which has a base and walls extending from the base and delimiting a transport chamber. The container consists of particulate foam made of expanded polypropylene (EPP), which has a plurality of foam particles sintered to each other, wherein the foam particles each comprise an outer wall and a substantially hollow inner chamber enclosed by the outer wall. The outer walls of the foam particles at the inner faces of the container which delimit the transport chamber are thicker than in the remaining regions of the container and form an inner skin on the container.

The invention relates to a pocket (10) having a receptacle space (23) for piece goods, which receptacle space (23) is delimited by two side walls (18), a base wall (12) and a ceiling wall (14) made from flexible tarpaulin material, wherein each side wall (18) connects a longitudinal side (16) of the base wall (12) to a longitudinal side (17) of the ceiling wall (14). There is provision according to the invention for a fastening element (26) which extends at least a distance along the narrow side (24) and has a hook part (30) which protrudes beyond the narrow side (24) for being hooked into a rail in a transport frame to be attached to the ceiling wall (14) at each of its narrow sides (24) which extend between the longitudinal sides (17).

The invention relates to a method of shaping hollow boards (11) that consist of a thermoplastic material and that have at least one cavity (17) in the interior of the board that is open towards the board edge (18). According to the inventive method, said cavity (17) is sealed at the board edge (1), thereby closing the cavity towards the exterior in a substantially gas-tight manner. Once the cavity (17) is closed in this manner, the hollow board (11) that has been softened by heating is shaped by a shaping pressure to which it is subjected from the exterior. The invention also relates to a device for carrying out the inventive method. The invention provides a method and a device which prevents the interior structure of the hollow board being deformed in an undesirable manner during the shaping process.
