Vacuum cover

Abstract

Disclosed herein is a vacuum cover, which is coupled to an object to define storage space isolated from the exterior, and moves in a direction that reduces the volume of the storage space due to its elasticity, thus discharging air from the storage space, therefore improving sealing ability and preventing food stored in the storage space from contacting the air. The vacuum cover is made of elastomer, such as silicone rubber, and integrally has a member for air-tightly contacting an object or a valve for supplying or exhausting the air. The vacuum cover includes an elastic body, which isolates storage space from an exterior and is deformed so that air is exhausted from or supplied to the storage space, and a valve provided at a predetermined position on the body to discharge and/or supply the air from and/or to the storage space.

1 . A vacuum cover, comprising:
 an elastic body, isolating storage space from an exterior, and deformed so that air is exhausted from or supplied to the storage space; and   a valve provided at a predetermined position in the body to discharge and/or supply the air from and/or to the storage space.   
     
     
         2 . The vacuum cover according to  claim 1 , wherein the valve comprises a protruding press part, and an air inlet/exhaust part formed by incising an upper surface of the press part. 
     
     
         3 . The vacuum cover according to  claim 2 , wherein an exhaust passage facing the air inlet/exhaust part is shaped so that an upper portion of the exhaust passage is narrow and a lower portion of the exhaust passage is wide. 
     
     
         4 . The vacuum cover according to  claim 1 , wherein the valve comprises:
 a coupling part inserted into a valve mounting hole of the body;   a support part contacting a lower surface of the body, and positioned under the coupling part; and   a shutting part placed on an upper surface of the body, and shutting an air discharge hole formed in the body.   
     
     
         5 . The vacuum cover according to  claim 4 , wherein the coupling part of the valve has a length such that it is movable up and down relative to the body. 
     
     
         6 . The vacuum cover according to  claim 4 , wherein the valve further comprises a grip part provided on an upper portion of the shutting part. 
     
     
         7 . The vacuum cover according to  claim 1 , wherein a sealing protrusion is provided at a predetermined position on the body that contacts a corresponding object, which defines the storage space isolated from the exterior along with the body, and
 an air layer is defined between the sealing protrusion and the corresponding object.   
     
     
         8 . The vacuum cover according to  claim 1 , wherein removal prevention parts are provided on a predetermined position on the corresponding object, defining the storage space, isolated from the exterior along with the body, and a predetermined position on the body, which contacts the corresponding object, and are coupled to each other through a male-female-coupling method. 
     
     
         9 . The vacuum cover according to  claim 1 , wherein a skirt extends from an outer edge of the body. 
     
     
         10 . The vacuum cover according to  claim 1 , wherein the body has a dome shape. 
     
     
         11 . The vacuum cover according to  claim 10 , wherein a thin part is provided inside the edge of the body contacting the corresponding object which defines the storage space, isolated from the exterior along with the body. 
     
     
         12 . The vacuum cover according to  claim 1 , wherein a depressed part is provided on the body to be positioned around the valve, and prevents the valve from projecting out. 
     
     
         13 . The vacuum cover according to  claim 1 , wherein the body is formed to have a single structure through injection molding, and is made of elastomer. 
     
     
         14 . The vacuum cover according to  claim 1 , wherein the body and the valve are integrated into a single structure through injection molding, and are made of elastomer. 
     
     
         15 . The vacuum cover according to  claim 2 , wherein the air inlet/exhaust part of the valve has a diagonal shape. 
     
     
         16 . The vacuum cover according to  claim 3 , wherein the air inlet/exhaust part of the valve has a diagonal shape.
