Carry-on luggage

Abstract

A carry-on luggage includes a housing composed of a right half shell and a left half shell, each half shell including a base layer made from a thermosetting polymeric material (TS) by molding and a protective layer made from a thermoplastic polymeric material (TP) and molded on the outer surface of the base layer. Thus, the housing of the carry-on luggage has excellent impact resistance and toughness.

What is claimed is: 
     
         1 . A carry-on luggage, comprising a housing, a plurality of wheels and a handle, wherein:
 said housing comprising a base layer made from a thermosetting polymeric material (TS), and a protective layer made from a thermoplastic polymeric material (TP) and covered over at least one surface of said base layer.   
     
     
         2 . The carry-on luggage as claimed in  claim 1 , wherein said protective layer is covered over an outer surface of said base layer. 
     
     
         3 . The carry-on luggage as claimed in  claim 1 , wherein said housing further comprises a protective layer arranged on an inner surface of said base layer. 
     
     
         4 . The carry-on luggage as claimed in  claim 3 , wherein said protective layer is made from a thermoplastic polymeric material (TP). 
     
     
         5 . The carry-on luggage as claimed in  claim 1 , wherein said thermosetting polymeric material (TS) is selected from the group of epoxy and polyester. 
     
     
         6 . The carry-on luggage as claimed in  claim 1 , wherein said base layer has contained therein carbon fibers. 
     
     
         7 . The carry-on luggage as claimed in  claim 1 , wherein said thermoplastic polymeric material (TP) is selected from the group of acrylonitrile-butadiene-styrene (ABS), polypropylene (PP), polycarbonate (PC), polyethylene (PE), thermoplastic Polyurethane (TPU), polyamide (PA) and their composites. 
     
     
         8 . The carry-on luggage as claimed in  claim 1 , wherein said base layer is composed of multiple layers.
