う。 When storing sake, etc. in a bottle, it is essential to put a stopper on the bottle to prevent dust in the outside air and insect pests such as flies from entering, and accurate sealing is essential to prevent the release of the active ingredients. This is important in preventing dispersion. However, for such bottles of sake, etc., the bottle stopper that has been reshaped under the heat-fastening conditions at the time of sealing is used as a replacement stopper, and the bottle is used until the contents are used up to seal the inside of the bottle. However, when the outside air warms up in a bottle with a stopper, the pressure of the air sealed inside the bottle increases, and if a bottle sealed with a stopper is brought onto an aircraft. Due to the drop in external pressure, the bottle stopper may come off. In other words, for example, if a 1.8-capacity sake bottle is stored with a replacement stopper at 15℃, the ambient temperature is 20℃.
Under normal temperature change conditions , such as when the temperature rises to
and increases by 0.007Kg/cm 2 (7g/cm 2 ), and the area of the part that receives the internal pressure of the replacement stopper is approximately 2.7cm 2 , so it is approximately 19g.
The uncorking force of However, the weight of the replacement stopper is 3.2 ~
3.5g, and the frictional resistance when uncorking a stopper (replacement stopper) made of a general low-polymerized polyethylene elastomer that has a conventional insertion part inside the bottle mouth and a part covering the outer periphery of the bottle mouth is
Since it weighs around 10g, there is a high possibility that the cap will come off even if the temperature changes after replacing the cap as described above. In fact, the external temperature changes during storage often exceed the above, and replacement stoppers often slip out and fall. Therefore, in the case of the bottle stopper mentioned above, the circumferential surface of the part inserted into the bottle mouth is roughened, or a special aluminum foil material is attached to increase the frictional force, thereby preventing the above-mentioned slipping out. However, this method requires extra processing or materials, and the liquid inside the bottle adheres to the bottle, increasing slippage, so it is not always possible to obtain the desired prevention of slippage. In addition, in the case where the frictional force is increased as described above, the frictional resistance of the insertion part inside the bottle mouth, which is originally a guide to the inside of the bottle mouth, becomes large, resulting in a large insertion force or removal when inserting and removing the bottle from the bottle mouth. It requires force and has the disadvantage of not being able to be installed and removed smoothly.

状通気部５を形成したものである。 The present invention was devised after consideration to eliminate the disadvantages and shortcomings of the conventional products as described above.The embodiment of the present invention is explained with reference to the attached drawings. The bottle stopper 1 inserted into the bottle mouth 11 of the body 10 has an inner bottle mouth insertion part 2 and a bottle mouth outer peripheral covering part 3 made of a synthetic resin material such as the above-mentioned low polymerized polyethylene elastomer as shown in FIG. As shown in FIG.
A joint part 4 is formed to be joined to the bottle part 10 for adhesive sealing, and the covering part 3 extends beyond a sealing groove part 12 formed in a known manner at a position close to the bottle opening of the bottle body 10 and is properly lowered therefrom. In other words, at least the portion of the inner surface of the covering portion 3 corresponding to the sealing groove 12 is narrowed into the groove 12 together with the thin metal sealing material 7 at the time of sealing, and the temperature at the time of sealing is around 60°C. The sealing remolding reduced diameter portion 8 is remolded so as to fit into the groove portion 12 even after the sealing material 7 narrowed as shown in FIG. 2 is opened and removed by heating as shown in FIG. Then, a ring-shaped small protrusion 6 is attached to such a resealing reduced diameter part 8.
A slit-like ventilation portion 5 is formed along the outer peripheral surface of the bottle mouth on the small protrusion 6.

The sealing operation may be performed using a thin metal sheet sealing material that covers and locks up to the 16th part of the top stepped part of the metal canopy that is covered up to 9 parts, and any of these may be used. The present invention can be effectively employed. Regarding the shape of the bottle stopper 1, the one shown in the attached drawing is the bottle opening insertion part 2.
is recessed upwards to the top plate portion and formed into a hole shape, but in some cases, this configuration may be opened in the top plate portion and recessed downward from the opening to form a hole-shaped opening for the bottle mouth insertion portion 2.
(Therefore, the bottom surface of the bottle opening insertion part 2 is closed.).

によつて再び密閉状態が形成される。 To explain the operation of the device according to the present invention as described above, it is clear that at least the ventilation portion 5 is formed in the portion where the remolded reduced diameter portion 8 is formed by sealing as described above. When such a product is inserted into the bottle mouth 11 as a replacement stopper after opening, the bottle mouth bulging part 11b, which has a swollen vertical cross section, passes through the remolded diameter reducing part 8. The insertion resistance is high up to this point, but after passing through, this resistance rapidly decreases, and the reduced diameter part 8 fits into the groove part 12, and is instantly pushed to the state where it is completely joined to the joint part 4, and The remolding projection 8 also joins the groove 12. That is, the top surface of the bottle mouth is joined to the joint portion 4, and a stable sealing state is accurately formed. In other words, in this state, even if the ventilation part 5 is located in the groove part 12 and ventilation is carried out in this part, a stable sealing state is formed by the connection between the joint part 4 and the top surface of the bottle mouth, and the components of the liquid contained in the bottle are etc. will not dissipate into the atmosphere.
However, when a replacement stopper is installed in this way, the vapor pressure inside the bottle increases due to the rise in temperature of the outside air, or the pressure inside the bottle increases due to the lower pressure of the outside world at high places such as inside an aircraft. If the bottle is worn out, the bottle stopper 1 will be pushed up due to the high pressure inside the bottle, but if the bottle stopper is pushed up from the bottle mouth and tries to come out, the small protrusions 6 will act as a certain resistance. It is clear that the vapor pressure caused by the temperature difference as described above does not escape from the mouth part of the bottle above the groove part 12, and if the bottle stopper is pushed up a little under the above-mentioned high pressure condition inside the bottle, the vent part 5 is pulled out and located below the circumferential portion of the bottle mouth, which has a vertically bulging cross-sectional structure. The high-pressure gas inside the bottle automatically escapes to the outside air from the ventilation part 5, and the inside of the bottle becomes equal to the atmospheric pressure condition of the outside world, so that further escape of the bottle stopper is accurately prevented. When the temperature of the content liquid decreases, a sealed state is again formed by external pressure.

果の大きい考案である。 According to the present invention as explained above, the covering part 3 extending downward beyond the sealing groove part 12 in the bottle body 10 effectively covers the outer surface part of the bottle opening, and wipes this part as well. This effectively prevents flies and other pests from approaching or dust from adhering to the circumference of the bottle opening, but a sealing material is applied to the groove 12 on the covering part 3 to effectively prevent it. As a result, a remolded reduced diameter portion 8 that fits into the groove 12 is formed, and the sudden insertion resistance of the small protrusion 6 in the remolded reduced diameter portion 8 after passing through the bottle mouth bulging portion 11b is reduced. As a result of the reduction, the top surface 11a of the bottle mouth is completely joined to the joint part 4, and a stable attachment relationship to the bottle mouth as a replacement cap can be established. Since the ventilation portion 5 as described above is formed, when a pressure difference occurs between the inside and outside of the bottle and the bottle stopper tries to come out due to high pressure inside the bottle, a preferable ventilation is created between the bottle and the peripheral side surface of the bottle mouth. In addition, by the slip-off resistance on the lower side of the bulging portion 11b of the bottle mouth of the small protrusion 6, it is possible to effectively prevent the bottle stopper from popping out or slipping out. Since slippage is prevented, there is no need for special processing or special attachment members to increase the frictional force, such as at the insertion part of the bottle mouth, making it easier to manufacture the bottle stopper and reducing costs. The intraoral insertion part only needs to act as a guide during insertion and removal, and since the resistance during insertion and removal is due to the divided small protrusions 6 in the remolded part 8, it is relatively light. It also has the effect of smoothing the operation of loading and unloading the bottle from the mouth of the bottle, and is a highly effective device in terms of practical production.
