Description

[Detailed description of the invention] This invention covers a stopper made of synthetic resin with a cap-shaped lid made of a thin metal plate such as aluminum, and the cap-shaped lid is tightly bound and sealed. In a tank lid with a stopper, in which the lower half of the lid is incised and removed and the stopper is used repeatedly, the lower circumferential wall of the cap-shaped lid is recessed into a groove provided on the outer surface of the bottle mouth in order to securely attach the lid. When inserted and connected, the force that pulls the peripheral wall downward may cause the cut line made at the joint between the cap-shaped lid and the stopper to open and become unsightly. This prevents the inconvenience caused by the rotation of the needle relative to the enlarged stitches, and an example of its implementation will be explained with reference to the drawings.

Reference numeral 1 denotes a plug body made of synthetic resin, with an annular groove 3 surrounding the circumferential surface of an upper collar body 2, and an inner plug 4 inserted into the center of the bottom surface of the plug body. Further, a vertical knurling 6 was formed on the lower outer circumferential surface of the collar body 2 below the groove 3.

The lower part of the flange body 2 below the concave groove 3 is formed into an outwardly arcuate projecting edge 5 to ensure the closure of the widening, and a knurling 6 is formed on the outer surface of the arcuate projecting edge 5. provided.

7 is a cap-shaped lid made of a thin metal plate such as aluminum that covers the outer surface of the plug body 1; A cut line 8 was made along the bottom to separate the cap-shaped lid 7 into upper and lower parts.

An annular recessed groove 9 with a gap of 10 is formed at at least one place in the middle, surrounding the peripheral wall of the cap-shaped lid 7 that overlaps the outer surface of the knurling 6 on the outer periphery of the collar 2, and this is formed into an arcuate ridge 5. It was inserted into the six knurls formed on the outer surface of the.

Incidentally, the recessed groove strips 9 may be formed in a plurality of strips.

The lower part of the cap-like lid 7 is recessed into an annular groove provided on the outer periphery of the seed opening, and is connected to the embankment body a. An incision line 11 for the lid was provided.

When this type of tank lid is attached to a bottle, its lower part is recessed into an annular groove provided in the embankment, but in this process, the downward pulling force that acts on the cap-shaped lid due to the recess is applied to the recess. The cut line 8 in the groove 3 extends downward, causing an unsightly appearance where the cut line 8 opens downward, and as a result, the connection between the stopper 1 and the cap-like lid 7 may become loose. However, when according to the present invention, the cut line 8 Concave groove 3
At the bottom, the circumferential wall of the cap-shaped lid 7 is aligned with the arc-shaped ridge 5 formed on the stopper 1, and a vertical knurl 6 is provided on the outer surface of the ridge 5 with an annular groove 9 interrupted at the iron part.
Since the cap-like lid 7 and the stopper 1 are brought into contact with each other at the arc-shaped surfaces, and the knurling 6 and the recessed groove 9 are engaged with each other in the vertical and horizontal directions, when closing the bottle opening, The force acting downward on the cut line 8 can be suppressed to prevent the cut line 8 from opening, and the lower half of the cap-like lid 7 is formed by the engagement of the recessed groove 9 with a spacing of 10 and the knurl 6. This has the effect of reliably preventing the inconvenience of rotation relative to the stopper 1.

Claims (1)

[Scope of utility model registration request] An inner plug 4 is provided protruding from the center of the lower surface of the flange body 2 that forms an annular groove 3 surrounding the outer periphery, and bulges outward in an arc shape on the lower outer periphery of the flange body 2 below the groove 3. The outer surface of the stopper body 1 made of synthetic resin is formed with a rounded edge 5 and has longitudinal knurling 6 on its outer surface, and is covered with a cap-shaped lid 7 made of a metal plate, and the upper part thereof is covered with an annular groove. A space 10 is formed in the middle on the circumferential wall of the cap-like lid 7 which is recessed into the cap body 3 and combined with the stopper 1 and overlaps the outer surface of the knurl 6.
A substantially annular recessed groove 9 having a shape is formed and inserted into the outer surface knurling 6 of the protruding edge 5, and the recess of the cap-shaped lid 7 and the bottom of the recess into the groove 3 are cut and separated vertically along the cutting line 8. , a tank lid with a stopper, which is formed by providing a cut line 11 for opening the lid on the lower peripheral wall of the cap-shaped lid 7.
