Abstract: A process for the manufacturing of non-reinforced load carriers (1) of thermoplastic material. Sheet-shaped work pieces (2) and extended bar sections (3) are manufactured by means of an extruder. The work pieces (2) and bar sections (3) are allowed to cool and post-shrink after the manufacturing. An upper and a lower deck member (11 and 12 respectively) are molded in a number of molds comprising mold halves. A first mold contains shaping cavities being a negative representation of the upper deck member (11). A second mold gives shape to a lower deck member (12). The work pieces (2) are molded against each one cavity by means of vacuum and are pressed together while still hot whereby a hollow unit is formed. Skids (3′) are molded in a similar way. The parts are allowed to cool and post-shrink whereupon they are joined with each other via a number of joining areas (10).

Abstract: A collapsible transport and storage container comprising a base member (2) and inwards foldable side walls (1) which are moveably attached to the base member (2) via hinges. The container is provided with upper hinge members (3′) at the side walls (1) and lower hinge members (3″) at the base member (2). The lower hinge members (3″) are provided with assembly grooves (36). The assembly grooves (36) are applied in an angle (A) from the base surface of the base member (2). The side walls (1) are provided with one or more locking profiles (37) at their respective lower ends (1′) which are intended to cooperate with the assembly grooves (36) during assembly and disassembly. The locking profiles (37) are provided with a locking edge (37′) which runs against a wall member (33) during the main part of the folding and unfolding motion of the side wall (1). The invention also relates to a method to assemble such a container.
