Although the appearance is very good without change, the bottle mouth is sealed with an inner stopper made of heat-resistant elastic plastics whose main body is a bottomless insertion tube fitted and inserted. The cap is used to prevent the inner plug from being lifted up by the pressure in the bottle and is prevented from floating by the cap, so that accurate sealing without liquid leakage or gas leakage is performed. . However, if it is desired to open the bottle, if the above-mentioned cap is removed, the insertion tube portion of the inner plug inserted into the bottle mouth portion has an appropriate elasticity that can be lifted by the pressure in the bottle filled with the carbonated beverage. When the cap is removed, the cap is lifted and opened without rotating the inner plug, and at the same time, a popping sound is emitted.

２ｅが張出されている。BRIEF DESCRIPTION OF THE DRAWINGS FIG. In the figure, reference numeral 1 denotes a cap made of an aluminum alloy thin plate having a pill fur proof function, and a remaining ring portion 1c is continuously provided below a cap through a broken broken connection portion 1b. This pill fur proof cap is similar to the pill fur proof cap described above, but a flange holding portion 1a having an enlarged diameter for receiving a flange portion 2e of an inner plug 2 described later is formed at an upper inner end of the cap 1. Reference numeral 2 denotes an inner plug made of a heat-resistant elastic plastic having a moderate elasticity such as a polyethylene resin-based or other polyolefin-based elastomer. The inner plug 2 is inserted and held in a bottle mouth at normal pressure. However, when the bottle is filled with a carbonated beverage, the bottle can be lifted by the pressure in the bottle, and in the sealed state in which the bottle is not lifted by the cap 1, the gas pressure applied to the bottle causes the bottle to adhere to the inner surface of the mouth of the bottle and leak. The upper end of the insertion tube portion 2a having elasticity and outer diameter enough to prevent gas leakage is sealed with a canopy portion 2d. The lower end portion of the insertion tube portion 2a has a peripheral surface for pressure release. A short-diameter reduced-diameter guide portion 2b provided with a plurality of ridges 2c is provided.
At the upper end of the insertion tube 2a, a sealing flange 2e made of the same material is projected.

を発して開栓される。When the inner stopper 2 is plugged into a bottle opening filled with carbonated beverage and the cap 1 is fitted and fixed to the bottle opening, the pressure inside the bottle becomes inside the insertion tube 2a. Even if it is applied, the gas pressure applied to the inside of the insertion tube portion 2a elastically deforms so as to be in close contact with the inner surface of the mouth of the bottle 10 to maintain airtightness, and to appropriately prevent liquid leakage and gas leakage. Also, when opening the cap, if the cap 1 is removed, the inner cap 2 will be lifted upward by the pressure inside the bottle without turning, and will be lifted upward by the pressure inside the bottle, and will emit a "pong" sound unique to champagne bottles. Is done.

If a short cylindrical diameter reducing guide portion 2b in which a plurality of ridges 2c for pressure release are arranged on the peripheral surface at the lower end portion of
During tapping, the reduced-diameter guide portion 2b can be easily inserted into the mouth of the bottle 10, and the cap 2 is transferred to the tapping machine while the cap 2 is temporarily held in the mouth of the bottle 10. However, since the pressure inside the bottle is released to the outside from the gap formed between the inner surface of the bottle and the reduced-diameter guide portion 2b by the pressure releasing ridges 2c, the cap 1 does not fall, The plug operation can be performed efficiently.

If a flange 2e for sealing is protruded from the upper end of the insertion tube 2a as in the embodiment, the flange 2
e is deformed and adhered to the top surface of the bottle opening to further improve the sealing performance of the cap.

ることとなる。Next, the step of plugging the plug 2 and attaching the cap 1 will be described. As shown in FIG. 3, the inner plug 2 is inserted into the inside of the cap 1 and its flange 2 is inserted.
e is engaged with the flange holding portion 1a of the cap 1 and is temporarily held at the mouth of the bottle 10 with the reduced diameter guide portion 2b. Thread. In this case, the inner plug 2 is formed of an elastic material and
The insertion tube portion 2a is also fitted and held in the bottle mouth portion at normal pressure, but is adjusted to an elasticity and an outer diameter dimension that can be lifted by the pressure in the bottle filled with carbonated beverage, The force required for tapping is small, and mounting can be performed efficiently.

After the attachment is performed, the inner plug 2 is firmly fixed to the bottle 10 with the cap 1, and the insertion tube portion 2a of the elastic inner plug 2 swells due to the internal pressure and the bottle opening Since the flange portion 2e, which is in close contact with the inner surface of the bottle and extends from the upper end of the inner plug 2, is in close contact with the top surface of the bottle, excellent airtightness can be secured. Further, since the inner plug 2 is formed of a material having heat resistance, it can sufficiently withstand a sterilization treatment at 85 ° C. or higher even if the content is filled with a fruit juice-containing carbonated beverage.

As shown in FIG. 5, when the cap 1 is rotated in the opening direction, the point where the ring portion 1c is cut off from the dashed connecting portion 1b and the ring portion 1c remains on the skirt portion 12 of the bottle 10 has a conventional pill fur proof function. The cap is similar to the cap, but at this time the cap 2 is lifted and opened by the pressure inside the bottle at the same time that the cap 1 is removed, and a popping sound is emitted. In addition, since the insertion tube portion 2a of the inner stopper 2 is formed of a material having elasticity and is adjusted to an outer diameter dimension such that the insertion tube portion 2a naturally floats in a state of being inserted into the bottle opening portion, the conventional hard material is used. The force required for opening is very small as compared with a stopper made of a synthetic resin, and in the embodiment, the flange 2e of the inner stopper 2 is used.
Is temporarily held in the flange holding portion 1a whose diameter has been increased, and if the cap 1 is rotated and removed, the inner plug 2 is lifted up and opened, so that it is extremely safe without jumping out.

で経済性に優れたものとなる。Further, in the above-described structure, the vertical dimension can be reduced to about 2/3 as compared with the conventional pill fur proof cap made of aluminum alloy, so that the amount of the aluminum raw material used is small, and The capping is also shallow drawing, so that the thickness can be reduced and the cost of aluminum raw materials can be greatly reduced. Further, in the conventional case, the drawing process is performed twice for deep drawing, whereas once drawing is sufficient,
In the subsequent steps, the conventional one required several steps such as a frame cutting step for horizontal cutting, a winding step, and a step of processing a transverse cutting line, whereas the present invention requires one step for a shallow drawing.
It is possible to make it turn. On the other hand, since the inner plug is also thinner than the conventional one, the material cost is reduced to about 1/3, and the total cost of the present invention is extremely low and the economy is excellent.

In this case, the same operation as the aluminum alloy cap is performed. Of course, the effect can be obtained. If a synthetic resin cap is used, it can be equipped with a pill fur proof function that has a ring part for retention.

ところは極めて大である。As is apparent from the above description, the present invention does not require a large force at the time of tapping and opening, is easy to handle, and exhibits excellent assembling work and opening work. It is possible to produce sound even when opening the plug, but it is extremely safe because the plug does not fly,
Furthermore, it is excellent in heat resistance, can be sterilized at 85 ° C. or more, and can be filled with contents containing fruit juice. Therefore, the present invention is a bottle sealing device for carbonated beverage bottles that has eliminated the conventional problems. Both the inner stopper and the cap have a simple structure and are easy to mass-produce, and the stopper of the stopper and the mounting of the cap are also conventional. Since a capping machine can be used, there is an advantage that there is no burden on equipment costs, and it greatly contributes to industrial development.
