Deform-Proof Cup

Abstract

A novel cup is revealed. The cup is deform-proof. A body part of the cup has lateral-oriented fibers. By using the lateral-oriented fibers together with a rim part surrounding an opening part of the cup, the cup is not easily deformed on being held by hand. The present invention can be applied to cups with different heights for strengthening the body part, reducing weight of the body part and lowering production cost.

What is claimed is: 
     
         1 . A deform-proof cup, comprising
 a body part, said body part comprising a plurality of lateral-oriented fibers;   an opening part, said opening part being located at an end of said body part;   a rim part, said rim part being located to surround said opening part; and   a closing part, said closing part being located at another end of said body part opposite to said end of said body part.   
     
     
         2 . The deform-proof cup according to  claim 1 ,
 wherein said body part, said rim part and said closing part are made of paper; and height of said body part is longer than diameter of said opening part.   
     
     
         3 . The deform-proof cup according to  claim 1 ,
 wherein said body part and said closing part are made of paper; said rim part is made of plastic; and height of said body part is longer than diameter of said opening part.   
     
     
         4 . The deform-proof cup according to  claim 3 ,
 wherein said plastic is selected from a group consisting of polyproylene (PP), polyethylene (PE) and polyethylene terephthalate (PET).   
     
     
         5 . The deform-proof cup according to  claim 3 ,
 wherein said rim part is made of a biomass material, a biodegradable material and poly lactic acid (PLA).   
     
     
         6 . The deform-proof cup according to  claim 3 ,
 wherein said rim part is made of a biomass plastic.
