Embodiment Construction

[0018] Such as figure 1 The shown luggage case comprises two components 1a, 2a between which at least partly an adhesive material 3 is firmly connected by bonding.

[0019] These two components 1a, 2a are preferably an outer shell 1a and a reinforcement frame 2a made of polymeric material, but obviously these two components 1a, 2a can be any two components on a luggage case that must be firmly connected together.

[0020] For example, the connection between attachments or accessories such as handles, locks, hinges and the trunk frame can be bonded.

[0021] In a preferred embodiment, at least one of the two components 1a, 2a joined together by the bonding material 3 is made of thermoplastic material, eg PC, PC / ABS, PP, HDPE.

[0022] Each of the two housings 1a, 1b, preferably stamped or injection molded from sheet metal, has a raised outer surface 4a, 4b visible from the outside, as well as an opposite inner surface 5a, 5b and a closed-loop peripheral surface 6a, 6b .

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.

Description

technical field [0001] The invention relates to a lightweight luggage case according to the preamble of claim 1 and a method of manufacturing a lightweight luggage case according to the preamble of claim 8 . technical background [0002] Existing suitcases are mainly divided into two types: flexible suitcases and rigid suitcases. [0003] A case where maximum performance is required from luggage is air transport. In fact, the suitcase must be light in weight so as not to excessively reduce the maximum capacity of the passenger's carry-on items, and it must be strong so as to fully protect the passenger's items and avoid collisions caused by the airport's automatic luggage allocation device as much as possible. [0004] Flexible luggage, usually made of synthetic materials or fibers, is lightweight and flexible, but is prone to tearing and does not effectively protect the contents from impacts. [0005] Rigid luggage generally has an outer shell made of a rigid or polymeric...
