Cup with anti-slipping and heat insulation effects

Abstract

A cup with anti-slipping and heat insulation effect has a body and a surrounding slice. The body has a surrounding wall. The surrounding slice is mounted around the surrounding wall and has an external surface and multiple protrusions. The multiple protrusions are formed on the external surface of the surrounding slice. The multiple protrusions are staggeredly disposed into regular grids. Multiple intervals are formed between the surrounding slice and the surrounding wall, and each interval is hollow. The multiple protrusions can increase the anti-slipping effect, such that the users may hold the surrounding slice stably. The cup has a good heat insulation effect because the multiple intervals are formed between the surrounding slice and the surrounding wall.

1 . A cup with anti-slipping and heat insulation effects comprising:
 a body having
 a surrounding wall having
 an external surface; 
 a bottom edge; and 
 a top edge; and 
 
 a bottom portion connected to the bottom edge of the surrounding wall; and 
   a surrounding slice mounted around the external surface of the surrounding wall, and having
 an external surface; 
 an internal surface; 
 multiple protrusions formed on the external surface of the surrounding slice and staggeredly disposed into regular grids, each four of the multiple protrusions forming a group, and the four protrusions of each group connected to each other and disposed in a ring shape, wherein multiple intervals are formed between the surrounding slice and the surrounding wall, and each one of the intervals is hollow. 
   
     
     
         2 . The cup as claimed in  claim 1 , wherein the surrounding slice corresponds in shape and size to the surrounding wall, is fan-shaped, and has
 two side edges; and   two connecting edges formed on the two side edges respectively, and the two connecting edges overlap and stick to each other, wherein the multiple protrusions are entirely formed on the external surface of the surrounding slice without forming on the two connecting edges.   
     
     
         3 . The cup as claimed in  claim 1 , wherein each one of the protrusions is shaped as an elongated rectangle. 
     
     
         4 . The cup as claimed in  claim 2 , wherein each one of protrusions is shaped as an elongated rectangle.
