Abstract

The present invention relates to a quadruple sealing structure of a can cover. As an upper sealing part (111) formed on the upper part of a can (110) is inserted into a circular groove (11) of an inner cover (10), the upper surface of the can (110) is covered and then sealed. As an inner O-ring (20) is inserted into the circular groove (11) of the inner cover (10) and is in close contact with the upper sealing part (111) of the can (110), sealing force is improved. As an outer coupling ring (30) including multiple coupling protrusions (31) is inserted and fastened into multiple coupling grooves (12) formed on the outer circumferential part of the inner cover (10), the upper sealing part of the can is in close contact, in triplicate, with the left side, right side, and top surfaces by the inner cover, that is, three surfaces, thereby sealing seal the top surface of the can and blocking communication with the outside so that a sealing state is maintained for simplifying the structure by sealing the top surface of the can without a sealing member and for reducing production costs. As the outer circumferential part of the inner cover is fastened by means of an external coupling ring for coupling by a coupling groove, not a screw structure, the top surface of the can is quadruple sealed so that the upper sealing part of the can inserted into the circular groove of the inner cover is prevented from being separated, thereby being capable of improving coupling force.

Description

technical field [0001] The present invention relates to a quadruple sealing structure for can lids, and more particularly, to a quadruple sealing structure for can lids, which covers and seals the upper surface of a can so that when the can is opened, the engraving along the upper surface After the sealing of the trace line, the contents stored in the jar are prevented from leaking to the outside. Background technique [0002] Usually, as figure 1 As illustrated, a seal 2 is formed by the score line, which has a thickness on one side of the upper surface of the can that is smaller than the thickness of the upper surface of the beverage can, and a pull tab 3 is fixed to the upper central part of the can. In this case, no score line is formed at the portion where the pull tab 3 is mounted, that is, the portion that is near the upper central portion of the can at the outer periphery of the seal 2d, so that the seal 2 is not separated from the upper surface of the can . In ad...
