Cup-shaped container

Abstract

A cup-shaped container is formed by a cup body in a cylindrical shape and having a first end and a second end, a hollow chamber formed in the cup body and between the first and second ends, a cup opening with an upwardly opened opening formed at the chamber, a cup rim defined an inner periphery of the cup opening. The cup body has an outwardly protruding flange formed at an outer periphery of the cup opening, and a flat attachment surface formed at tops of the cup rim of the cup body and the flange, so that two adjacent cup bodies can be stacked with each other, and the container has the effects of simple structure, easy manufacture, and low cost.

What is claimed is: 
     
         1 . A cup-shaped container, comprising a cup body substantially in a cylindrical shape and having a first end and a second end, a hollow chamber formed inside the cup body and between the first and second ends and having a cup opening with an upwardly opened opening and configured relative to the first end of the cup body, and a cup rim defined at an inner periphery of the cup opening, characterized in that the cup body has an outwardly protruding flange formed at an outer periphery of the cup opening, and a flat attachment surface formed at tops of the cup rim and the flange of the cup body, such that the adjacent cup bodies can be stacked with each other by using the flat attachment surface of the first end to constitute a simple structured and stably stackable cup-shaped container. 
     
     
         2 . The cup-shaped container according to  claim 1 , wherein the cup body has an outer edge with a diameter gradually increasing from the first end to the second end, and curving downwardly and being folded at the second end. 
     
     
         3 . The cup-shaped container according to  claim 1 , wherein the second end of the cup body has an inwardly concave portion disposed at the middle, and a circular abutting surface formed at the periphery of the inwardly concave portion of the second end and provided for erecting the cup body from a plane. 
     
     
         4 . The cup-shaped container according to  claim 3 , wherein the circular abutting surface has a width of 0.1 mm˜0.5 mm. 
     
     
         5 . The cup-shaped container according to  claim 3 , wherein the flange of the cup rim of the cup body is protruded from an outer wall of the cup body by a distance of 0.05˜0.3 mm, and the flat attachment surface has a width of 0.1 mm˜0.5 mm. 
     
     
         6 . The cup-shaped container according to  claim 1 , wherein the cup body is made of polyethylene terephthalate (PET). 
     
     
         7 . The cup-shaped container according to  claim 2 , wherein the cup body is made of polyethylene terephthalate (PET). 
     
     
         8 . The cup-shaped container according to  claim 3 , wherein the cup body is made of polyethylene terephthalate (PET). 
     
     
         9 . The cup-shaped container according to  claim 4 , wherein the cup body is made of polyethylene terephthalate (PET). 
     
     
         10 . The cup-shaped container according to  claim 5 , wherein the cup body is made of polyethylene terephthalate (PET).
