DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a bottle cap,
More specifically, the present invention relates to a bottle cap which is attached to a bottle of glass, synthetic resin, or the like and has a spout that can be freely opened and closed, and particularly to a bottle cap used for beverages.

[0002]

2. Description of the Related Art Conventionally, as a bottle cap, there is a bottle cap comprising a cap body attached to a bottle and a spout slidably fitted to the cap body.

[0003] Such bottle caps have been used for various purposes such as shampooing and detergent storage, but recently, attention has been paid to uses for beverages.

[0004] As a bottle cap for beverages, for example, there is one as shown in FIG. That is, the bottle cap includes the cap body 52 and the spout 41, and is fitted to the mouth 43 of the bottle 42 so as to be freely detachable.

The cap main body 52 has a multi-stage cylindrical shape, and has a fitting portion 44 fitted externally to the mouth 43 of the bottle 42,
A first step portion 45 extending from 44, a second step portion 46 extending from the tip of the first step portion 45, and a second step portion As if coming out from step 46, the second step
A plug 48 is supported by several support pieces 47,...

A tapered lower locking portion 48 is formed between the first step portion 45 and the second step portion 46.
An upper locking portion 49 that protrudes in a circumferential shape is formed in the second step portion 46.

The spout 41 is formed with a spout 50 into which the stopper 48 can be inserted, and a spout 49 is fitted to the cap body 52 so as to be able to slide up and down.

A locking portion 51 which can be locked with the lower locking portion 48 and the upper locking portion 49 is provided inside the spout 41.
Are provided so as to protrude circumferentially.

Therefore, when the spout 41 is pulled up, the locking portion 51 is locked by the upper locking portion 49, so that the upward movement of the spout 41 is restricted, The outlet 50 is detached from the stopper 48 and opened, and the bottle 42 is opened.
When the spout 41 is pressed down, the locking portion 51 is locked by the lower locking portion 48, and the downward sliding of the spout 41 is restricted, The plug portion 48 is fitted into the spout 41 of the spout 41 and closed, and the outflow of the beverage in the bottle 42 is regulated.

[0010]

However, in the conventional bottle cap for beverages, since the spout 41 is always exposed, dust and the like easily adhere to the spout 41 and are very unsanitary. .

In such a bottle cap for beverages, a finger is placed near the spout 50 of the spout 41,
Since 41 was lifted up to open and pushed down to close it, there was a possibility that germs might adhere near the spout 50, which was extremely unsanitary.

In order to solve such a problem, as shown in FIG. 24, the spout of the head of the container body can be moved up and down, and the up and down movement is restricted to a certain range by a stopper 54. With a stopper 56 adapted to open the spout and to be closed in the lowered position, forming a flange 57 at the upper end of the stopper 56 which projects laterally outside the spout, and which can be picked up
A stopper 58 is provided on the stopper so as to cover the inner surface of the stopper, and the cap 58 is forcibly pushed down to engage with the lower peripheral edge of the stopper at the upper end of the stopper in a snap fastening manner. The projection 59 is formed so as to deviate from the peripheral edge.

However, in such a bottle cap, it is necessary to forcibly disengage the snap-like engagement and pull up the cap as it is, and the resistance and impact for pulling up the cap are relatively large. However, there is a problem that the lifting operation cannot be easily performed.

The present invention has been made to solve the above-mentioned problems, and can prevent dust and the like from adhering to a spout, and can be opened hygienically without directly contacting a spout. An object of the present invention is to provide a plug that can be plugged and closed, and to significantly reduce resistance and impact when the cap is pulled up.

[0015]

In order to solve the above-mentioned problems, a bottle cap according to the present invention is provided with a cap body 2 attached to a bottle, and fitted to the cap body 2,
A spout 3 which can be moved up and down between an upper opening position for opening the spout 17 and a lower closing position for closing the spout 17, and which can be fitted to the spout 3 and can be attached to and detached from the cap body 2 And a cover cap (4), wherein the spout (3) is moved to an upper opening position by rotation of the cover cap (4).

In the bottle cap having the above structure, the spout 3 is moved to the upper opening position by the rotation of the cover cap 4, so that the spout 3 is easily pulled upward by the rotational force of the cover cap 4. .

On the other hand, the cover cap 4 is
When the cover cap 4 is mounted, the spout 3 moves to the closing position in accordance with the movement of the cover cap 4, and the spout 17 is closed.

Therefore, when the contents are drinks, after the drink is finished, the spout 3 is closed only by attaching the cover cap 4 to the cap body 2 without directly touching the spout 3.
