Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for closing and safely opening an effervescent beverage bottle containing carbon dioxide gas, and in particular, for opening an effervescent beverage bottle containing carbon dioxide gas such as sparkling wine. The present invention relates to a beverage safety cap in which a plastic cap is prevented from jumping out of a bottle opening by a predetermined distance or more.

[0002]

2. Description of the Related Art Conventionally, in a beverage bottle filled with carbon dioxide gas such as sparkling wine, a cap for sealing the bottle mouth is pressed and fixed to the bottle mouth in order to prevent the cap from popping out due to internal pressure during the market distribution process. By attaching a fastener, or providing a screw part at the bottle mouth, and having a structure to lock the screw part with the cap,
There has been proposed a cap that can omit a fastener.

That is, as shown in FIG. 11, Z1 is a beverage bottle filled with carbon dioxide gas such as sparkling wine, etc., an external screw Z3 is provided in a bottle mouth Z2, and the outer diameter of the bottle is below it. A skirt Z4 formed by bulging is formed. It is a cap Z5 that can be sealed in a screwing manner corresponding to this bottle Z1, and an inner screw Z7 corresponding to the outer screw Z3.
And a plug portion Z6 having a shape corresponding to the inner diameter of the bottle mouth portion Z2 and fitted in a sealed state.

[0004]

The cap constructed as described above holds the cap body in one hand until the cap is completely opened at the time of opening, so that the cap as the stopper is a bottle. Although it is possible to prevent it from jumping out of the mouth, the stopper is not necessarily opened in the expected style due to the habits and habits of the user, and a stopper that presses and fixes the cap to the bottle mouth is attached When the opening operation is performed in the same manner as the classic type, that is, grasping the bottle body with both hands, pushing out the cap with the thumbs of both hands,
If the cap is opened in a well-known style, the cap will pop out of the bottle mouth as if it were a classic one with ordinary fasteners. In addition, unlike the classical plug using cork, the cap with the above structure allows resealing, so it can be freely opened and then closed, reducing the internal pressure of carbon dioxide. It cannot be clearly distinguished whether the bottle is in a state of being opened or a bottle having an unopened internal pressure sufficiently. For this reason, for example, a case can be assumed in which a bottle whose internal pressure has been reduced is opened at a celebration seat, and the opening sound becomes insufficient.

[0005] Therefore, in the beverage safety cap according to the present invention, even if it is opened in various styles commonly performed, the cap only protrudes from the bottle mouth within a safe range. Provided is a beverage safety cap capable of surely sounding when the bottle is opened by clarifying the presence or absence.

[0006]

As a means for solving the above problems, a beverage safety cap according to the first aspect of the present invention comprises a plug fitted into a mouth of a bottle, and a mouth of a bottle. The head of the cap having an internal thread engaged with the external thread provided on the outside of the head, and formed partially continuous below the head, and can be separated into a long shape by a bridge portion. A band portion and locking means positioned below the band portion and engaged below the bead portion of the bottle, wherein the head portion is separated by the bridge portion when the head portion is separated from the bottle after opening. It is characterized in that it is configured so as to be continuous with the locking means that is engaged with the lower part of the bead portion of the bottle by being extended through the provided band portion.

According to a second aspect of the present invention, in the first aspect of the present invention, the plug seals the internal pressure from the bottle to the inner wall of the mouth of the bottle when the outer screw and the inner screw are engaged. A plurality of contact portions for rotating the head in the opening direction, and in a process in which the external screw and the internal screw are in an engagement relationship, the contact portion is in contact with the inner wall of the mouth of the bottle. At least a part of the bottle is not in contact, the head is further rotated in the opening direction, and immediately after the outer screw and the inner screw are disengaged from each other, the contact portion contacts the entire inner wall of the mouth of the bottle. It is characterized by having been formed so that.

[0008] The invention described in claim 3 is claim 1 or 2.
In the invention described in the above, the locking means is formed in a circumferential shape, and the circumferential shape can be opened and deformed.
Alternatively, a weakening portion is provided, and in a state where the head is separated from the bottle, the final bridge portion and / or the weakening portion is torn, so that the head, bridge portion, band portion, locking means, final bridge portion and / or weakening portion are provided. Wherein the entire cap comprising: is detachable from the bottle.

In each figure, 1 is a bottle, 1a is a bead portion, 2
Is the bottle mouth, 3 is the external screw, 4 is the skirt, 5 is the cap
(Overall), 6 is a plug part, 7 is an internal screw, 8 is a contact part, 9 is a contact part, 10 is a screw end position, 13 is an umbrella part, 13a is a head, 13
a 'is non-slip, 13b is a band portion, 13c locking means, 13d is a bridge portion, 13e is a bent portion, 13f is a weakened portion, 14d is a final bridge portion, 15 is a distance, 16 is a distance, 17 is a distance, 18 is position, 19
Is a flat part, and 26 and 27 are rings.

1 to 8, three external threads 3 are provided on the outer periphery of a bottle mouth 2 of a bottle 1, a skirt 4 is provided below the external threads, and a skirt 4 is provided further below. A bead portion 1a is formed to bulge outward from the outer periphery of the bead 4. On the other hand, the cap 5 screwed to the bottle 1 has an umbrella portion 13 on the outside by integral molding of plastic, a plug portion 6 extends in the center, and is gripped by the user above the umbrella portion 13 when the cap is opened. The intended head 13a is provided with a non-slip 13a ', and below the head 13a, a band portion 13b and a locking means 13c forming a pill fur proof structure are provided with a bridge portion 13d and a final bridge portion. It is provided integrally via 14d. A bent portion 13e is provided between the lowermost band portion 13b and the locking means 13c. On the other hand, on the inside of the head 13a of the umbrella portion 13, there are provided multiple internal screws 7 corresponding to the external screws 3 of the bottle 1 to be used. The occupied width of the inner screw 7 in the axial direction is made equal to the width of the bottle mouth portion 2 and the skirt 4, and in particular, the lower end of the inner screw 7 is limited to reach the screw end position 10. I have. The plug portion 6 is provided with two types of protrusions that come into contact with the inside of the bottle 1.
One protrusion is a contact portion 8 for improving the sealing performance between the bottle 1 and the cap 5 when the cap 5 is completely screwed into the bottle 1, and the other protrusion is to gradually open the cap 5. In the process of closing the bottle, the contact portion 9 is in contact with the bottle 1 until the moment when the sealed state of the cap 5 is released (see the enlarged view of FIG. K). The position of this contact part 9 is the distance obtained as a result of subtracting the screw start height distance 16 from the distance 15 between the screw end position 10 of the inner screw 7 and the cap head.
It is provided at or below the position 18 of the plug part 6 positioned by 17 (see FIG. L).

The position 18 has the following meaning. Referring to FIG. L, the cap 5 tightened to the bottle 1 is sufficiently rotated in the opening direction to complete the lifting operation of the cap caused only by the relative rotation between the bottle 1 and the cap 5 when the cap is opened. In this state, the cap 5 is designed to be fitted to the bottle only by the contact of the plug portion 6.
{A}. If the contact part 9, which is the last contact part when the cap comes off, is designed to be above the position 18 in the state where the cap lifting operation is completed, the cap 5 is opened in the opening direction. In the course of turning, the contact portion 9 is separated from the bottle mouth portion 2 and the internal pressure sealed in the bottle is released at this point, so such a design {B}
Then, when the cap is removed from the bottle, the internal pressure in the bottle has already been gradually released, so that a vigorous “pong” is not pronounced and a unique opening sound cannot be obtained. Therefore, if the bottle and the cap meet the conditions set forth in the design {A} above, ie, if the contact 9 is provided below the position 18, for example at the end of the plug 6, then the screws Only when the cap 5 has been lifted by only the additional work of pushing up the cap with a finger or the like, a vigorous “pong”
Can be opened with the pronunciation of When the contact portion 9 is provided at the end, the contact portion 9 can be formed simply by widening the end opening of the plug portion 6 so as to inscribe the bottle.

The above-mentioned contact portion 9 is generally formed such that the thickness of the plug portion 6 rises partially in the shape of one peak. The shape is as shown in the ring 27 in Fig. N, in which case the cap is opened without the pleasant sound of "pon" under the relatively common situation where the cap is opened at an angle to the bottle. There are many cases that are done. The reason is that the contact surface between the plug portion and the inner wall of the bottle mouth loses parallelism with respect to the bottle mouth as shown in FIG. N, and as a result, the compressed air in the bottle is opened while the compressed air partially escapes. It is because. Therefore, the contact portion 9 or the ring 26 in the embodiment of the present invention has a shape in which the plug portion 6 is thickened in a ring shape as shown in FIG. I have. Further, the width of the flat portion 19 is formed to be about twice the thickness of the ring. Flat part like this
With the provision of 19, the contact surface inscribed with the bottle is maintained substantially parallel to the bottle mouth as can be understood from FIG. The bottle is opened, and the compressed air in the bottle is released almost at the same time without unevenness, so that a pleasant opening sound of "pong" is stably and reliably obtained.

In the above embodiment of the present invention, other embodiments as described below can be obtained as required. FIG. R is a front view of a cap having a two-layered band portion, particularly showing a state before folding a pill fur proof structure at a lower end of the cap. In this connection, FIG. S is a rear view of FIG. R, FIG. T is a front view of the pill fur proof structure of FIG. R in a folded state, FIG. U is a rear view of FIG.
Is a bottom view of FIG. T, and FIG. W is a plan view of FIG. As shown in these drawings, by changing the size of the cap or the softness of the material, it is possible to form the band portion into two layers. Preferably 3 as shown in FIGS.
The layer provides a band of a desired length even if the band is not completely separated. Even if it is made of hard plastic, three layers are easier to open than two layers, and at the time of opening, there is a high probability that the cap head 13a is farther away from the mouth of the bottle. Since the sound makes an open sound,
Refreshing opening is possible. On the other hand, in the case of two layers,
Since the band part at the time of opening is compact, it is excellent in that the band part remaining after opening has a simple and beautiful impression.

Although the bands shown in the above embodiments are all formed in a single separated state, a plurality of bands, such as two, may be formed as desired. As a result, the width of each band can be reduced, and even if an unexpected crack enters the band, in the case of a plurality of bands,
It is possible to reduce the probability that the band portion becomes discontinuous at the time of opening.

In the above embodiment, the band portion is separated into a long shape by the opening operation, so that even if the closing operation is performed again, the band portion is probably greatly expanded compared to the initial state. It was found that the plug was opened and then closed, and a new pill fur proof structure has been proposed. Therefore, the structure of a cap for a carbonated beverage such as sparkling wine has been specifically described above. However, when using only this new pill fur proof structure, for example, the plug portion is not necessarily required. That is, it is also possible to apply this structure as a general pill fur proof stopper.

In the above embodiment, the final bridge portion 14d and the weakening portion 13f are provided so as to be able to select a continuous or discontinuous form with the locking member 13c, which is the lower end of the band portion, as desired. The final bridge portion 14d has a shape wider than the bridge portion 13d as shown, but may have a perforated structure adjusted at appropriate intervals as desired. The weakened portion 13f has a perforated structure, but if necessary, the final bridge portion 14d or the bridge portion 1f may be used.
It is possible to have a bridge shape having the same structure as 3d. Further, a weak portion (not shown) such as a perforated structure or a bridge shape is also provided for a continuous portion that is partially continuous with the lower end of the cap head 13a and the uppermost band portion.
Can be newly provided. By the way, the newly provided weakened portion includes a bridge portion 13d and a final bridge portion 14d.
In the case of a structure that is easier to cut than the weakened portion 13f and the weakened portion 13f, the head 13a of the cap when the cap is opened is such that the newly provided weakened portion is cut first, so that the head 13a pops out alone as before. The likelihood increases. Therefore, the newly provided weakened portion is formed by devising the bridge portion 13d, the last bridge portion 14d, and the weakened portion 13f by, for example, widening the interval between perforations.
It is desirable to have a structure that is hard to be cut as compared with FIG.

[0019]

According to the invention defined in claim 1, a cap having a plug portion fitted into the mouth of the bottle and an internal thread engaged with an external thread provided outside the mouth of the bottle. A head part, a band part formed continuously with the lower part of the head part, and separable into a long shape by a bridge part, and a lower part of the band part, and a lower part of the bead part of the bottle The head is extended through a band portion separated by a bridge portion in a state where the head portion is separated from the bottle after opening, so that the head portion is below the bead portion of the bottle. It is characterized in that it is configured to be in a continuous state with the engaging means in the engaged state.The band part is separated into a long shape by the opening operation,
Even if the plugging operation is performed again, the band portion probably swells greatly compared to the initial state, so it is apparent that plugging has been performed once and then plugged, and a so-called pill fur proof structure is formed. . After the cap is opened, the head of the cap is continuous with the locking means, so that it does not fly over the length of the band portion, so that it is safe for surrounding objects or people. -After the cap is opened, the head of the cap is spirally continuous with the locking means, so the head of the cap that flew outwards is absorbed by the spiral band, so the cap is opened. Even in the event that the cap is later returned to the hand of the person performing the opening, the force is reduced as compared to a straight string.

According to a second aspect of the present invention, in the first aspect of the present invention, the plug seals the internal pressure from the bottle to the inner wall of the mouth of the bottle when the outer screw and the inner screw are engaged. A plurality of contact portions for rotating the head in the opening direction, and in a process in which the external screw and the internal screw are in an engagement relationship, the contact portion is in contact with the inner wall of the mouth of the bottle. At least a part of the bottle is not in contact, the head is further rotated in the opening direction, and immediately after the outer screw and the inner screw are disengaged from each other, the contact portion contacts the entire inner wall of the mouth of the bottle. The cap is designed so that the head of the cap does not fly to the surroundings and does not return to the user's hand with a large amount of energy. Unlike the type with a stopper, the stopper is opened with rotational force. In it may be easily unplugging women because it is possible to realize a state of unplugging verge. In addition, the invention disclosed in claim 2 is a cap that is designed to be opened by a two-stage configuration of a first stage of turning the cap and a second stage of pulling out the plug, so that the most tightly fitted state is achieved. The cap is released by means for turning the cap in the first stage, and the shape of the plug is devised so that the first stage alone will not completely open the cap. Therefore, the cap pulling operation performed in the second stage can be stopped at a short distance,
It is safe because the timing at opening can be taken. Moreover,
After the cap is opened, the head of the cap is continuous with the locking means in the form of a string, so that the cap does not fly over the length of the band portion, thereby further improving safety.

The third aspect of the present invention is the first or second aspect.
In the invention described in the above, the locking means is formed in a circumferential shape, and the circumferential shape can be opened and deformed.
Alternatively, a weakening portion is provided, and in a state where the head is separated from the bottle, the final bridge portion and / or the weakening portion is torn, so that the head, bridge portion, band portion, locking means, final bridge portion and / or weakening portion are provided. Since the entire cap consisting of the cap can be separated from the bottle, after opening the cap, the head of the cap is continuous with the locking means in the form of a string. Since there is an inconvenience in appearance or work, it is possible to easily remove only the band portion or both the band portion and the locking means by "finally pulling the band portion". That is, when the purpose is to remove only the band portion, one condition is that the locking means itself is formed continuously in the circumferential direction below the bead portion of the bottle,
Another condition is to provide a final bridge between the locking means and the band. Under these conditions, the action of "finally pulling the band portion" described above causes only the final bridge portion to separate, and the band portion comes off the bottle with the locking means left on the bottle side. Next, when the purpose is to remove both the band portion and the locking means, there are the following three types of patterns. The first pattern is that when the locking means is scattered in the separated state with respect to the lowermost band portion (see FIG. X), that is, the locking means is in a tongue state which can be separated in the circumferential direction. Under these conditions, it is necessary to provide a final bridge that can open and close the lowermost band in the circumferential direction, and the final bridge is separated by the above-mentioned “finally pulling the band further” action. Accordingly, the locking means originally formed in a separated state can be naturally removed together with the lowermost band portion. The second pattern is provided on condition that the locking means itself is continuously formed in the circumferential direction below the bead portion of the bottle, and that a weakening portion that allows the locking means to be separable in the circumferential direction is provided. is there. In the case where the lowermost band portion is discontinuous in the circumferential direction and is not provided with the final bridge portion, the lowermost band portion is provided on the locking means itself by the above-mentioned "finally pulling the band portion further" action. Only the weakened portion can be torn, and both the band portion and the locking means can be removed from the bottle (see FIG. Y). As a third pattern, the locking means itself is formed continuously in the circumferential direction below the bead portion of the bottle,
In addition, it is a condition that a weakening portion that allows the locking means to be separable in the circumferential direction is provided. In the case where the lowermost band portion is formed to be continuous in the circumferential direction through the final bridge portion, the above-mentioned "finally pulling the further band portion" is provided on the final bridge portion and the locking means itself. By tearing both of the weakened portions, both the band and the locking means can be removed from the bottle (FIG. Z)
reference). -In a conventional pill fur proof structure stopper, the cap portion is formed so as to be separated from the band portion at the lower end of the head portion of the cap. Unless the action of "pulling the band portion" is performed, the band portion is continuous with the band portion, and the band portion has a sufficient length to open the cap. There is no problem with opening even if it is not removed. Therefore, the head of the cap can be maintained in a state of being connected to the bottle via the band portion, and acts, for example, to prevent the cap from being lost. Further, as described above, it can be removed in a form according to various requests. And it is also free to re-close after the band is completely separated from the bottle, and in this case, the band which has a slightly looser curvature than the initial state is located at the lower end of the head of the cap. Since the band hangs, the deformation of the band is a sign, and it is possible to clearly inform the user that the band has been used once.
