Foldable cup provided with a reinforcing structure

Abstract

A foldable cup provided with a reinforcing structure includes: a cup body, a shape-fixing ring nested on the opening of the cup body, and a cup cap fitted to the shape-fixing ring. When the cup body is deformed due to the effect of force, the side wall of the cup body is prevented from experiencing a large twist due to the deformation of the opening of the cup, thereby effectively alleviating the disadvantages of an existing foldable cup: the existing foldable cup easily topples and falls due to the deformation of the opening of the cup, causing a liquid in the cup to be splashed. Further, when the side wall of the cup body is extruded, the liquid in the cup does not flow out from the joint position between the shape-fixing ring and the cup cap, thereby improving the practicability of the foldable cup.

What is claimed is: 
     
         1 . A foldable cup provided with a reinforcing structure, comprising:
 a cup body having a opening, and at least two folding portions on a lateral surface of the cup body, wherein the at least two folding portions are spaced and annularly arranged on a lateral surface of the cup body, the cup body is foldable via the two folding portions; and   a shape-fixing ring combined with the cup body and nested on an inner surface of the opening of the cup body.   
     
     
         2 . The foldable cup provided with the reinforcing structure as claimed in  claim 1 , wherein a plurality of positioning flanges are spacedly provided on an inner surface of the shape-fixing ring. 
     
     
         3 . The foldable cup provided with the reinforcing structure as claimed in  claim 1  or  2 , wherein the shape-fixing ring extends upward to cover a top edge of the opening of the cup body in an annular manner. 
     
     
         4 . The foldable cup provided with the reinforcing structure as claimed in  claim 3 , wherein the at least two folding portions are a first folding area and a second folding area, the first folding area is formed by being recessed in a circular shape from an outer surface of the cup body, and is located at a middle area and close to an upper half of the cup body, so that the portion of the cup body below the first folding area is foldable upward in a portion of the cup body above the first folding area, and the portions of the cup body below and above the first folding area have their inner surfaces facing each other; the second folding area is formed by being recessed in a circular shape from an inner surface of the cup body, and is located at a middle portion and close to a lower half of the cup body, so that the portions of the cup body above and below the second folding are foldable against each other and have their outer surfaces facing each other. 
     
     
         5 . The foldable cup provided with the reinforcing structure as claimed in  claim 4 , wherein when the cup body is in a folded state, a lower edge of the shape-fixing ring is higher than a position of the two folding areas. 
     
     
         6 . The foldable cup provided with the reinforcing structure as claimed in  claim 1  or  2 , wherein the at least two folding portions are a first folding area and a second folding area, the first folding area is formed by being recessed in a circular shape from an outer surface of the cup body, and is located at a middle area and close to an upper half of the cup body, so that the portion of the cup body below the first folding area is foldable upward in a portion of the cup body above the first folding area, and the portions of the cup body below and above the first folding area have their inner surfaces facing each other; the second folding area is formed by being recessed in a circular shape from an inner surface of the cup body, and is located at a middle portion and close to a lower half of the cup body, so that the portions of the cup body above and below the second folding are foldable against each other and have their outer surfaces facing each other. 
     
     
         7 . The foldable cup provided with the reinforcing structure as claimed in  claim 6 , wherein when the cup body is in a folded state, a lower edge of the shape-fixing ring is higher than a position of the two folding areas. 
     
     
         8 . The foldable cup provided with the reinforcing structure as claimed in  claim 1  or  2 , wherein when the cup body is in a folded state, a lower edge of the shape-fixing ring is higher than a position of the at least two folding areas. 
     
     
         9 . The foldable cup provided with the reinforcing structure as claimed in  claim 5  further comprising a cup cap which is combined with the shape-fixing ring and has two ribs spaced in a vertical direction and arranged in an annular shape, when the shape-fixing ring is combined with the cup cap, the plurality of positioning flanges are restricted between the two ribs, and the two ribs are abutted against the inner surface of the shape-fixing ring. 
     
     
         10 . The foldable cup provided with the reinforcing structure as claimed in  claim 2  further comprising a cup cap which is combined with the shape-fixing ring and has two ribs spaced in a vertical direction and arranged in an annular shape, when the shape-fixing ring is combined with the cup cap, the plurality of positioning flanges are restricted between the two ribs, and the two ribs are abutted against the inner surface of the shape-fixing ring.
