Abstract

A closure of a vessel, comprises: a body mounted at a vessel inlet through which stuff contained in a vessel is outwardly discharged; a sealing member removing unit formed in the body, for removing a sealing member sealed at a vessel inlet when the body is separated from the vessel inlet, and storing the removed sealing member in the body; and a reinforcing member having a sealing member bonded thereto at the time of an induction manufacturing process, for storing the sealing member in the closure. The closure is manufactured by an induction process so that the sealing member bonded to the vessel inlet can be stored in the closure.

Claims

1. A closure of a vessel, comprising:

a body mounted at a vessel inlet through which stuff contained in a vessel is discharged out;

a sealing member removing unit formed in the body, for removing a sealing member sealing the vessel inlet when the body is separated from the vessel inlet, and storing the removed sealing member in the body; and

a reinforcing member having the sealing member attached thereto at the time of an induction manufacturing process, for storing the sealing member in the closure.

2. The closure of a vessel of claim 1, wherein the sealing member removing unit comprises:

a pressing plate disposed in the body, the pressing plate movable in upper and lower directions;

at least one cutter formed at an edge of a lower surface of the pressing plate in a circumferential direction, for penetrating the sealing member when the pressing plate is pressed, and for cutting the sealing member when the body is rotated;

a locking unit downwardly protruding from a lower surface of the pressing plate, for storing the sealing member cut by the cutter in the body; and

a connecting unit connecting an outer circumferential surface of the pressing plate with an inner circumferential surface of the body, and elastically transformed so that the pressing plate may move in upper and lower directions.

3. The closure of a vessel of claim 1, wherein the reinforcing member is formed to have a circular flat shape of a predetermined strength, and the sealing member is attached to the reinforcing member.

4. The closure of a vessel of claim 2, wherein the reinforcing member is formed to have a circular flat shape of a predetermined strength, and comprises:

a first through hole for passing the locking unit at a center thereof; and

second through hole of the same number of the cutters for passing the cutter at a circumference thereof.

5. The closure of a vessel of claim 4, wherein the reinforcing member is provided with a notch portion having a narrow area at a connection portion between the second through holes so as to be easily cut by the cutter.

6. The closure of a vessel of claim 3, wherein the reinforcing member is fittedly coupled to a locking groove formed at an inner circumferential surface of the body.

7. The closure of a vessel of claim 1, wherein the reinforcing member is formed as a circular ring shape, and is attached to an edge of the sealing member.

8. The closure of a vessel of claim 1, wherein adhesive melting at a low temperature is deposited on one surface of the sealing member, and adhesive melting at a high temperature is deposited on the other surface of the sealing member.

9. The closure of a vessel of claim 8, wherein the adhesive deposited on one surface of the sealing member has a melting temperature of 80°

˜

140°

.

10. The closure of a vessel of claim 8, wherein the adhesive deposited on the other surface of the sealing member has a melting temperature of 150°

C.˜

250°

C.

11. The closure of a vessel of claim 8, wherein the adhesive deposited on one surface of the sealing member is attached to the reinforcing member, and the adhesive deposited on the other surface of the sealing member is attached to the vessel inlet.

12. The closure of a vessel of claim 2, wherein the pressing plate is formed at a part of an upper surface of the body.

13. The closure of a vessel of claim 12, wherein the pressing plate is formed to be eccentric from the center of the upper surface of the body.

14. A process for manufacturing a closure of a vessel, comprising:

a first step of depositing adhesives melting at different temperatures on the respective surfaces of a sealing member;

a second step of attaching the sealing member to a reinforcing member at a low temperature;

a third step of mounting the reinforcing member to which the sealing member has been attached in a closure;

a fourth step of mounting the closure at a vessel inlet; and

a fifth step of heating the closure with a high temperature, and thereby attaching the sealing member to the vessel inlet.

15. The process of claim 14, wherein in the first step, adhesive having a melting temperature of approximately 120°

C. is deposited on one surface of the sealing member, and an adhesive having a melting temperature of approximately 180°

C. is deposited on the other surface of the sealing member.

16. The process of claim 14, wherein in the second step, the reinforcing member is bonded to the adhesive deposited on the sealing member and having a relatively low melting point, and then heated in a low temperature, thereby attaching the reinforcing member and the sealing member to each other.

17. The process of claim 14, wherein in the third step, the reinforcing member to which the sealing member has been attached is fittedly coupled to a locking groove formed in the closure.

18. The process of claim 14, wherein in the fifth step, the sealing member and the vessel inlet are attached to each other, and then are heated in a high temperature, thereby attaching the sealing member to the vessel inlet by the adhesive having a relatively high melting point.
