Description

[Detailed Description of the Invention] The present invention relates to the structure of a bottle lid for sealing the mouth of various bottles made of glass or plastic, such as liquor bottles.

The cap lid of conventional 1.81 bottles is sealed by locking onto an annular protrusion on the outer periphery of the bottle mouth, or has an inner stopper made of soft synthetic resin such as polyethylene that is sealed on the inner periphery of the bottle mouth, and the inner stopper of this inner stopper. It consists of a metal crown that fits on the outside, and these are integrally fitted to the mouth of the bottle, transported, and sold at stores.

To use, remove the crown with a bottle opener, then remove the inner stopper and dispense the liquid inside the bottle.

Therefore, the crown was no longer needed, and since the inner stopper was also completely removed from the mouth of the bottle, there was a risk that it would be lost.

In the present invention, the lower surface of the lid made of soft synthetic resin is formed into a double cylinder, and the inner cylinder is fitted around the outer periphery of the bottle mouth, while the cylindrical body is connected to the lower end of the lid. The lower end is formed into a skirt part that fits around the outer periphery of the bottle mouth, and a hinge part is left in the body part that connects the lid body and the skirt part, so that the lid body and the skirt part can be separated at will. This allows the bottle lid to be integrally molded, and the double cylindrical body of the lid enhances the sealing effect of the bottle, while also making it easy to open the lid.

Next, the present invention will be explained based on an example. In the figure,
Reference numeral 1 denotes a bottle lid made of a soft synthetic resin such as polyethylene, and a cylindrical or other inner stopper 6 is integrally provided on the lower surface of the lid body 3 in close contact with the inner circumferential surface of the opening of the bottle mouth 2.

An inner cylindrical body 7 is integrally protruded from the lower surface of the lid 3 on the outer circumferential side of the inner stopper 6 in a concentric circle with the inner stopper 6, and an annular protrusion on the outer periphery of the bottle opening 2 is formed on the inner periphery of the inner cylindrical body 7. It is equipped with an engaging part or a sealing part such as an annular protrusion 9 that engages with the strip 8.

Further, on the lower surface of the lid body 3, a groove 10 having a downwardly open annular shape or an arc shape with an appropriate gap size between the outer periphery of the inner cylindrical body 7 and the like is provided.
An outer cylindrical body 4 is integrally provided with a distance between the outer cylindrical body 4 and the inner cylindrical body 7, and the outer cylindrical body 4 and the inner cylindrical body 7 are connected by connecting pieces 11 at a plurality of locations at appropriate intervals in the circumferential direction.

At the lower end of the lid 3, a cylindrical body 4' is integrally formed at the lower end of the outer cylinder 4, etc., and the lower end of the body 4' is fitted onto the outer peripheral surface of the bottle mouth 2. It is configured in the skirt portion 5 to be worn.

A pair of left and right incision holes 12.12 are bored in the body part 4' between the outer cylinder body 4 and the skirt part 5 of the lid body 3 near one side of the body part 4'. .1
By reducing the wall thickness of the body 4' between the lid body 3 and
The outer cylinder body 4 and the skirt part 5 are integrally connected to each other by a hinge part 13, and windows 14 and 14 are formed in the hinge part 13 with equal upper and lower sides. The hinge part 13 is configured to be easily bent.

Further, a pair of upper and lower substantially parallel cut lines 15.15 are formed on the inner peripheral surface or outer peripheral surface of the trunk section 4' between the outer cylinder 4 and the skirt section 5 of the lid body 3. The cut lines 15.15 each start at least at or near the end of one of the incision holes 12, and begin at least at the end of the other incision hole 12 or near the same. so that the hinge part 13
It is not necessary to apply it to

The left and right incision holes 1 are formed on the outer surface of the body portion 4' at a midway point in the vertical direction of the pair of cut lines 15.15.
2.12 Holding piece 1 from near the end toward the hinge part 13
6 and 16 are integrally protruded, and an appropriate gap is provided near the tip of each gripping piece 16 between its inner surface and the outer surface of the body 4 so that the gripping piece 16 can be easily gripped. On the other hand, the inner surface of each gripping piece 16 and the outer surface of the outer cylinder 4 or the body 4' are integrally joined by thin temporary joint pieces 17 and 17.

The gripping pieces 16 may be provided on only one side, and the protruding direction of the gripping pieces 16 may be in an appropriate direction such as up and down or diagonally along the cylindrical axis of the body 4'.

Furthermore, reference numeral 18 denotes an ear provided on the outer surface of the lid body 3;
8 is provided on the outer cylindrical body 4 on the opposite side to the hinge portion 13.

As shown in FIG. 1, when the bottle cap 1 configured in this manner is pressed toward the upper surface of the bottle mouth 2 with the skirt 5 facing down, the inner circumferential surface of the skirt 5 will be aligned with the top surface of the bottle neck 2. At the same time, the inner stopper 6 on the lower surface of the lid body 3 engages with the inner peripheral surface of the bottle mouth part 2, and the annular protrusion 9 of the cylindrical body 7 engages with the annular protrusion 8 on the outer circumference of the bottle mouth part 2, resulting in a high bottle seal. Effects can be obtained.

To open this bottle lid 1, both gripping pieces 1 on the body 4' are used.
If one or both of the parts 6 and 16 are held and pulled radially outward along the circumferential direction of the body 4', the temporary joint pieces 17 and 17 with the outer surface of the outer cylinder 4 will be torn, and the body 4 will be separated. ' is torn along the score line 15.15, and the skirt part 5 and the lid body 3 can be separated leaving the hinge part 13.

Next, when the outer cylinder body 4 is pushed up by placing the thumb from below the ear part 18, the lower end side of the inner cylinder body 7 is deformed in the radial outward direction via the connecting piece 11, and the annular protrusion 9 of the inner cylinder body 7 and While the engagement with the annular protrusion 8 on the outer periphery of the bottle mouth part 2 is released, the seal with the inner peripheral surface of the bottle mouth part 12 by the inner stopper 6 is also released, and the lid body 1 is connected to the skirt part 5 at the hinge part 13. In this state, it comes off from the bottle opening as shown by the two-dot chain line in FIG.

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 addition, if the wall thickness of the inner cylinder body 7 on the inner peripheral side is formed thinner than the wall thickness of the outer cylinder body 4 of the lid body, it is possible to prevent the lid body 3 from being pushed up from the bottle opening 2 or when opening the bottle. At the time of sealing in the opposite direction, the inner cylinder body 7 is easily bent along with the groove 10 between the four cylinder bodies 7, and it becomes extremely easy to engage and disengage the bottle mouth part 2 with the outer circumferential annular protrusion 8.

In addition, a locking part such as an annular protrusion is provided on the outer peripheral surface of the bottle opening opposite to the inner peripheral surface of the skirt part at the lower end of the body, and an annular groove or a protrusion that engages with the locking part is also provided on the inner peripheral surface of the skirt part. By providing an engaging portion such as the above, it is possible to enhance the sealing effect of the bottle cap 1 when the bottle cap 1 is initially sealed, and to prevent the skirt portion from coming off.

In summary, according to the present invention, the lower surface of the lid into which the bottle opening is fitted is formed into a double cylindrical body, a cylindrical body is integrally provided at the lower end of the lid, and the body is Since the lower end skirt part is configured to fit around the outer periphery of the bottle mouth, the initial corking operation is extremely easy. The seal can be reliably sealed, and there is no need for a separate crown like in the past.

In addition, since the body is formed so that the lid and skirt can be separated leaving a hinge, opening can be done easily by hand without the need for a bottle opener, and the lid can be reused after opening. Moreover, since the lid body and the skirt part are connected by a hinge part, there is no risk of losing the lid body.

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 side 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.
