Description

[Detailed Description of the Invention] The present invention relates to a bottle lid for irradiating the opening of a bottle of various types of glass and plastic bottles such as liquor bottles.

The lower surface of the lid made of soft synthetic resin is formed into a cylindrical body, and this cylindrical body is fitted around the outer periphery of the bottle mouth as a lid for sealing the mouth of modern bottles containing sake, soy sauce, vinegar, juice, etc. It is configured to allow

In such a synthetic resin bottle cap, an annular projection locking portion is provided inside the cylindrical body to project inward, and this is locked to the lower end of the annular projection near the upper end of the outer periphery of the bottle mouth, thereby achieving the irradiation effect. However, if the cylindrical body is thin, it will easily deform due to external force and the irradiation effect will not be achieved.On the other hand, if the cylindrical body is too thick, the lid cannot be opened easily with fingers or the like.

In view of the above-mentioned conventional drawbacks, in the present invention, the circumferential wall of the soft synthetic resin lid body is made into a double cylinder, and connecting pieces are arranged at appropriate intervals in the circumferential direction in the gaps between the inner and outer cylinders, so that the two cylinders are integrated. On the other hand,
By providing a detachable skirt portion at the lower end of the peripheral wall of the lid body, the irradiation effect on the bottle mouth portion of the bottle lid is enhanced, and at the same time, it is possible to easily engage and disengage the bottle lid from the bottle mouth portion.

Next, the present invention will be explained based on an example. In the figure, 1 is a bottle lid made of soft synthetic resin such as polyethylene, and the lower surface of the lid body 3 has an inner circumferential surface of the opening of the bottle mouth 2. A cylindrical inner stopper 4 that is in close contact with the inner stopper 4 is integrally provided.

When a peripheral wall is integrally provided on the lower surface of the lid body 3 on the outer peripheral side of the inner stopper 4, an outer cylinder body 5 and an inner cylinder body 6 are integrally projected as a double cylinder concentrically.

The inner circumference of the inner cylindrical body 6 is provided with an engaging portion or a sealing portion such as an annular protrusion 8 that engages with an annular protrusion 7 near the upper end of the outer circumference of the bottle mouth portion 2 .

In addition, the outer periphery of the inner cylindrical body 6 and the inner periphery of the outer cylindrical body 5 located across a downwardly open annular or arcuate groove 9 with an appropriate gap size are arranged at a plurality of locations appropriately spaced in the circumferential direction. They are connected by a connecting piece 10 at.

Further, a cylindrical skirt portion 11 is integrally formed at the lower end of the inner cylinder 6 or outer cylinder 5 at the lower end of the lid body 3, and a cylindrical skirt portion 11 is provided at the inner lower end of the skirt portion 11 to protrude inward. Annular protrusion 1
2 is configured to be fitted into a lower annular groove locking part 13 on the outer periphery of the bottle mouth part 2.

The lower end of the lid 3 and the skirt part 11 are integrally connected to each other, and a thin line 14 or an interrupted cut line is formed on the inner peripheral surface or the outer peripheral surface thereof along the circumferential direction of the skirt part 11 to form a skirt. On any side of the skirt portion 11, a vertical score line 15 or an interrupted cut line, such as a thin diagonal direction, which communicates with the score line 14 from the lower end of the skirt portion 11 is provided. The base of the holding piece 16 is integrally provided in the vicinity of the holding piece 16.

The tip of the gripping piece 16 is connected to its inner surface and the skirt portion 11.
A suitable gap is provided between the outer surface of the gripping piece 16 and the skirt portion 11 so that the gripping piece 16 can be easily picked.
Or connect the outer surface of the peripheral wall of the lid body 3 with a thin temporary joint piece 17.17
It is continued in one piece.

The protruding direction of the gripping piece 16 may be any suitable direction along the cylinder axis of the skirt portion 11, such as vertically or diagonally.

Furthermore, as shown by the two-dot chain line in FIG.
8 may be made to protrude outside the lid body 3.

If the bottle lid 1 constructed in this way is pressed toward the upper surface of the bottle mouth part 2 with the skirt part 11 facing down as shown in FIG.
The inner circumferential surface of the skirt portion 11 fits into the annular groove locking portion 13 on the lower outer periphery of the bottle mouth portion 2, while the inner stopper 4 on the lower surface of the lid body 3 engages with the bottom outer circumference of the bottle mouth portion 2.
The annular protrusion 8 of the inner cylindrical body 6 engages with the annular protrusion 7 on the outer periphery of the bottle opening 2 on the inner peripheral surface, resulting in a high irradiation effect.

To open the bottle cap 1, hold the tip of the gripping piece 16 on the skirt portion 11 and pull it radially outward along the circumferential direction. 1
7 is torn, the skirt portion 11 is torn along the vertical score line 15 and the circumferential score/line 14, and the skirt portion 11 can be separated from the lower end of the lid body 3 and the outer periphery of the bottle mouth portion 2.

Next, when the outer cylinder body 5 is pushed up by placing the thumb from below the ear part 18, the lower end side of the inner cylinder body 6 is deformed in the radial outward direction via the connecting piece 10, and the annular protrusion 8 of the inner cylinder body 6 and While the engagement with the lower end of the annular protrusion 7 on the outer periphery of the bottle mouth part 2 is disengaged, the seal with the inner peripheral surface of the bottle mouth part 2 by the inner stopper 4 is also released, and the lid body 3 is shown by the two-dot chain line in FIG. It will come off from the bottle mouth like this.

Then, even when dispensing the liquid in the bottle thereafter, it is sufficient to simply engage and disengage the lid 3 from the bottle opening 2.

In this way, in the present invention, the peripheral wall of the lid body into which the bottle mouth part is fitted has a double cylindrical shape, and the cylindrical skirt part is integrally provided at the lower end of this peripheral wall of the lid body, and the skirt part is formed integrally with the lower end of the lid peripheral wall. Since the inner cylinder body and the skirt part are configured to fit around the outer periphery of the bottle mouth, the initial corking operation is extremely easy.Moreover, since the inner cylinder body and the skirt part fit around the outer periphery of the bottle mouth opening, the bottle neck can be easily sealed. It can be sealed reliably and does not require a separate crown like conventional ones.

In addition, a separation point such as a circumferential cut line is formed in the continuous part of the skirt part and the lid body, and a gripping piece is provided on the skirt part so that the skirt part can be separated from the lower end of the peripheral wall of the lid body. Since the opening operation does not require a bottle opener and can be easily done by hand, the lid body can be used again after opening.

Furthermore, since the inner cylindrical body of the lid body and the outer cylindrical body provided with a gap therebetween are connected by connecting pieces at appropriate locations in the circumferential direction, the inner cylindrical body deforms at the connecting pieces when the lid is closed. On the other hand, when the lid is opened, the inner cylindrical body deforms together with the outer cylindrical body through the connecting piece, and the peripheral surface of the inner cylindrical body other than the connecting piece becomes more easily deformed, making it difficult to open the lid. It has the effect of being able to be performed without applying much force.
