US 2020/0093234 A1 · MULTILAYER SHEET COMPRISING FABRIC AND RESIN, TRAVEL BAG CASE MADE THEREFROM, AND APPARATUS FOR MANUFACTURING SAME

Abstract

According to the present invention, in some embodiments, since a first resin, a first fabric and a second resin are layered and coupled to each other and the first resin and the second resin are coupled by through-holes of the first fabric, the first resin and the second resin are uniformly absorbed and coated on the surface of the first fabric, and the first resin, the first fabric, and the second resin are closely coupled to each other, thereby enabling a unique color of the first fabric to be displayed on the exterior, a travel bag having very excellent compactness, tensile strength and impact strength to be manufactured, a travel bag having excellent quality to be provided even if manufacturing costs and manufacturing processes are decreased, and a travel bag capable of maximizing user convenience and the operability of the travel bag by remarkably reducing the weight to be provided.

Dependent claims

A multilayer sheet constituting a case of a travel bag, the shape of which is made through plastic working such that articles are contained therein, the multilayer sheet having elastically restoring power and comprising:

a first fabric that comprises a fabric configured by coupling of fibers and has multiple through-holes penetrating the fabric;
a first resin laminated on the first fabric and absorbed and coated on a surface of the first fabric;
and
a second resin laminated on the first fabric from a side opposite to the first resin, absorbed and coated on the surface of the first fabric, and coupled to the first resin via the through-holes.

A case manufacturing device for manufacturing a case of a travel bag, the shape of which is made through plastic working such that articles are contained therein, the travel bag having elastically restoring power, the case manufacturing device comprising:

a first fabric supply portion configured to continuously supply a first fabric that comprises a fabric configured by coupling of fibers and has multiple through-holes penetrating the fabric;
a first resin supply portion configured to continuously supply a molten first resin in a directly downward direction;
a first roller and a second roller rotating in opposite directions while constituting a pair such that the first fabric and the first resin pass between the first roller and the second roller and become laminated on each other;
a second resin supply portion configured to continuously supply a molten second resin in a directly downward direction;
and
a third roller and a fourth roller rotating in opposite directions while constituting a pair such that the first resin, the first fabric, and the second resin pass between the third roller and the fourth roller and become laminated successively, thereby coupling and combining the first resin and the second resin via the through-holes.
