Abstract

This invention relates to a suitcase provided with two mouldings (2a, 2b), bonded to two shells (1a, 1b) respectively. The two mouldings (2a, 2b) each have a seat (7a, 7b) in which the terminal parts of the shells (1a, 1b) can be inserted. The interface surfaces are subjected to pre-treatment with cold plasma so as to form an activated surface layer (9) upon them which encourages adhesion between the adhesive (3) placed between the mouldings (2a, 2b) and the shells (1a, 1b) in order to bond them firmly together. In this way structured suitcases can even be obtained with thin and therefore very light shells whose resistance to squashing and impacts is due to the mouldings which can be manufactured with the necessary robustness. This invention also relates to a method for the production of such suitcases through the moulding of plastics materials.
