Method For Producing A Suitcase, And Such A Suitcase

Abstract

The invention relates to a method for producing a suitcase ( 1 ) comprising at least one suitcase shell (Ia, Ib) and at least one functional attachment ( 31 ) which is more heavily loaded during use and which is connected to the at least one suitcase shell (Ia, Ib) at a position provided for this purpose, wherein the suitcase shell (Ia, Ib) and the attachment ( 31 ) are at least partly made of a thermoplastic material. The invention also relates to a suitcase ( 1 ) produced using the aforementioned method. According to the invention, the attachment ( 31 ) is provided with a surface ( 10 ) at least on a part of the face facing the suitcase shell (Ia, Ib), said surface corresponding to the surface of the suitcase shell (Ia, Ib) at the specified position and complementing same after the connection process; the attachment ( 31 ) is positioned at the specified position on the suitcase shell (Ia, Ib); the attachment ( 31 ) is bonded to the suitcase shell (Ia, Ib); and the interior of the suitcase shell (Ia, Ib) is designed to be smooth, free of disruptions, and substantially free of interruptions.
