Beverage Receptacle and Valve for Injection-Via-Bottom Beverage Receptacle

Abstract

The present invention relates to a beverage receptacle and a valve for an injection-via-bottom beverage receptacle, and more particularly, to a beverage receptacle and a valve for an injection-via-bottom beverage receptacle, the valve including a cover part configured to open and close an injection port, a blade part disposed at a lower portion of the cover part, and an elastic part disposed between the cover part and the blade part to apply an elastic force to the cover part in a direction of closing the injection port, wherein the elastic part includes a through-hole into which a nozzle is fitted and an injection hole configured to communicate with the through-hole, and the elastic part is formed of a soft elastic material. Because a structure of the valve is extremely simplified and thus washing and drying thereof are facilitated, bacterial propagation can be prevented, maintenance and repair of the structure are facilitated, and assembly of the structure is facilitated because of the reduced number of components. Because the nozzle is fitted to the elastic part, a beverage is prevented from leaking between the nozzle and the valve when the beverage is injected, and because elastic deformation of the cover part is not necessary when a beverage is injected, the cover part may be formed such that watertightness is maximized.

1 . A beverage receptacle comprising:
 a receptacle main body including a bottom surface, in which an injection port is formed and a sidewall surrounding the bottom surface; and   a valve at which the injection port is installed, wherein:   the valve includes a cover part configured to open and close the injection port, a blade part disposed at a lower portion of the cover part, and an elastic part disposed between the cover part and the blade part to apply an elastic force to the cover part in a direction of closing the injection port;   the elastic part includes a through-hole into which a nozzle is fitted and an injection hole configured to communicate with the through-hole; and   the elastic part is formed of a soft elastic material.   
     
     
         2 . The beverage receptacle of  claim 1 , wherein:
 the cover part, the blade part, and the elastic part are integrally formed; and   the cover part and the blade part are also formed of the soft elastic material.   
     
     
         3 . The beverage receptacle of  claim 1  or  2 , wherein a maximum outer diameter of the cover part is formed to be larger than a maximum outer diameter of the elastic part. 
     
     
         4 . The beverage receptacle of  claim 1  or  2 , wherein the cover part is formed to be convex upward. 
     
     
         5 . The beverage receptacle of  claim 1  or  2 , wherein a vertical thickness of the blade part is formed to be larger than a vertical thickness of the cover part. 
     
     
         6 . The beverage receptacle of  claim 1  or  2 , wherein the blade part is formed to be concave downward. 
     
     
         7 . The beverage receptacle of  claim 1 , wherein a lower end of the injection hole is disposed higher than a lower surface of the bottom surface. 
     
     
         8 . A valve for an injection-via-bottom beverage receptacle, the valve comprising:
 a cover part configured to open and close an injection port;   a blade part disposed at a lower portion of the cover part; and   an elastic part disposed between the cover part and the blade part to apply an elastic force to the cover part in a direction of closing the injection port, wherein:   the elastic part includes a through-hole into which a nozzle is fitted and an injection hole configured to communicate with the through-hole; and   the elastic part is formed of a soft elastic material.   
     
     
         9 . The beverage receptacle of  claim 2 , wherein a maximum outer diameter of the cover part is formed to be larger than a maximum outer diameter of the elastic part. 
     
     
         10 . The beverage receptacle of  claim 2 , wherein the cover part is formed to be convex upward. 
     
     
         11 . The beverage receptacle of  claim 2 , wherein a vertical thickness of the blade part is formed to be larger than a vertical thickness of the cover part. 
     
     
         12 . The beverage receptacle of  claim 2 , wherein the blade part is formed to be concave downward. 
     
     
         13 . The beverage receptacle of  claim 2 , wherein a lower end of the injection hole is disposed higher than a lower surface of the bottom surface.
