Sealing member for vessel

Abstract

A vessel closure, and more particularly, a sealing member for sealing a vessel by being coupled to an inlet of the vessel, the sealing member being coupled to a vessel inlet of a vessel and sealing the vessel sealing member, wherein a vessel closure coupled to the vessel inlet, comprises a body mounted to the vessel inlet; a pressing plate disposed in the body so as to be movable up and down; one or more cutters formed on a lower surface of the pressing plate in a circumferential direction of the vessel inlet, and configured to punch the sealing member when the pressing plate is pressed, and to cut the sealing member when the body is rotated; a locking portion downwardly protruding from the lower surface of the pressing plate, and configured to accommodate the sealing member cut by the cutter in the body; and a connection portion connected between an outer circumferential surface of the pressing plate and an inner circumferential surface of the body, and elastically-transformed such that the pressing plate is movable up and down, wherein the sealing member has a disc shape in correspondence to the vessel inlet, a first cutting portion is formed at a position corresponding to the locking portion such that the sealing member is easily punched by the locking portion, and a second cutting portion is formed in a circumferential direction at a position corresponding to the cutter such that the sealing member is easily cut by the cutter, is disclosed.

 wherein the sealing member has a disc shape in correspondence to the vessel inlet,   a first cutting portion is formed at a position corresponding to the locking portion such that the sealing member is easily punched by the locking portion, and   a second cutting portion is formed in a circumferential direction at a position corresponding to the cutter such that the sealing member is easily cut by the cutter.   
     
     
         2 . The sealing member for a vessel of  claim 1 , wherein the locking portion is formed at a central part of the vessel inlet. 
     
     
         3 . The sealing member for a vessel of  claim 2 , wherein the locking portion comprises: a supporting rod downwardly protruding from a central part of the pressing plate; and one or more locking rods outwardly protruding from an end of the supporting rod. 
     
     
         4 . The sealing member for a vessel of any one of  claims 1 , wherein the sealing member comprises:
 a metallic layer formed of metallic material, and having an adhesive layer on a lower surface thereof such that the sealing member is adhered onto the vessel inlet; and a cover layer adhered onto the metallic layer,   wherein the first cutting portion and the second cutting portion are formed only at the cover layer.   
     
     
         5 . The sealing member for a vessel of  claim 4 , wherein the cover layer is not adhered onto the metallic layer at parts including the first cutting portion and the second cutting portion. 
     
     
         6 . The sealing member for a vessel of  claim 4 , wherein the metallic layer comprises aluminum, and the cover layer is formed of any one of paper and synthetic resin. 
     
     
         7 . The sealing member for a vessel of  claim 4 , wherein the first cutting portion has a shape of one or more lines formed to pass through the center of the vessel inlet. 
     
     
         8 . The sealing member for a vessel of  claim 4 , wherein the first cutting portion has any one shape of a polygonal shape and a circular shape each comprising the center of the vessel inlet. 
     
     
         9 . The sealing member for a vessel of  claim 4 , wherein the second cutting portion is implemented as a cutting circle of a circular shape concentric with the vessel inlet. 
     
     
         10 . The sealing member for a vessel of  claim 4 , wherein the second cutting portion is implemented as one or more arcs concentric with the vessel inlet. 
     
     
         11 . The sealing member for a vessel of  claim 4 , wherein the second cutting portion is formed between an inner circumferential surface of the vessel inlet and the center of the vessel inlet. 
     
     
         12 . The sealing member for a vessel of  claim 4 , wherein the first cutting portion and the second cutting portion are substantially formed in lines, or have widths spaced from each other. 
     
     
         13 . The sealing member for a vessel of  claim 4 , wherein one or more protrusion portions protrude more than an outer diameter of the vessel inlet. 
     
     
         14 . The sealing member for a vessel of any one of  claims 2 , wherein the sealing member comprises:
 a metallic layer formed of metallic material, and having an adhesive layer on a lower surface thereof such that the sealing member is adhered onto the vessel inlet; and a cover layer adhered onto the metallic layer,   wherein the first cutting portion and the second cutting portion are formed only at the cover layer.   
     
     
         15 . The sealing member for a vessel of  claim 14 , wherein the cover layer is not adhered onto the metallic layer at parts including the first cutting portion and the second cutting portion. 
     
     
         16 . The sealing member for a vessel of any one of  claims 3 , wherein the sealing member comprises:
 a metallic layer formed of metallic material, and having an adhesive layer on a lower surface thereof such that the sealing member is adhered onto the vessel inlet; and a cover layer adhered onto the metallic layer,   wherein the first cutting portion and the second cutting portion are formed only at the cover layer.   
     
     
         17 . The sealing member for a vessel of  claim 16 , wherein the cover layer is not adhered onto the metallic layer at parts including the first cutting portion and the second cutting portion.
