Protective article

Abstract

A protective article includes a press molded body including a core of a foam material and a rigid shell of a plastic material molded over the core to thereby enclose intimately the core. The foam material is selected from expanded polystyrene, expanded polypropylene, expanded polyethylene, and ethylene-vinyl acetate copolymer. The plastic material is selected from acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate, polyethylene, polypropylene, and polystyrene.

1 . A protective article comprising:
 a press molded body including a core of a foam material and a rigid shell of a plastic material molded over said core to thereby enclose intimately said core.   
   
   
       2 . The protective article of  claim 1 , wherein said foam material is selected from the group consisting of expanded polystyrene, expanded polypropylene, expanded polyethylene, and ethylene-vinyl acetate copolymer. 
   
   
       3 . The protective article of  claim 1 , wherein said plastic material is selected from the group consisting of acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate, polyethylene, polypropylene, and polystyrene. 
   
   
       4 . A bicycle helmet comprising:
 a press molded body including a core of a foam material and a rigid shell of a plastic material molded over said core to thereby enclose intimately said core.   
   
   
       5 . The bicycle helmet of  claim 4 , wherein said press molded body is formed with a plurality of vent holes. 
   
   
       6 . The bicycle helmet of  claim 4 , wherein said foam material is selected from the group consisting of expanded polystyrene, expanded polypropylene, expanded polyethylene, and ethylene-vinyl acetate copolymer. 
   
   
       7 . The bicycle helmet of  claim 4 , wherein said plastic material is selected from the group consisting of acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate, polyethylene, polypropylene, and polystyrene. 
   
   
       8 . The bicycle helmet of  claim 4 , wherein said press molded body defines an accommodating space, said rigid shell having an inner wall confining a top side of said accommodating space, said bicycle helmet further comprising a plurality of cushioning pads attached to said inner wall of said rigid shell.
