Description

[Detailed explanation of the idea] Purpose of invention Industrial applications The present invention relates to a seal for a carbonated beverage bottle.

Conventional technology A typical conventional ramune bottle is one in which a glass ball is placed inside the bottle during the bottle manufacturing process, the opening of the bottle is reheated to narrow it, and the ball is sealed inside the bottle. In this case, the sealing body is a ring-shaped gasket that fits over the enclosed ball and the bottle opening.The sealing method is to turn the bottle upside down after filling the liquid in the liquid filling process, and then use the internal pressure of the bottle to push the ball into the bottle opening. The bottle was sealed by pressing it onto a gasket, or by spraying and filling the bottle with liquid while the bottle was held upside down.

As shown in FIG. 2, the seal for a Ramune bottle that does not narrow the bottle opening consists of a spout member 20, a ring-shaped packing 21, and a ball 22. The ball 22 is placed in the bottle 23 in advance, and the bottle is closed. Fitting the ring-shaped packing 21 into the stepped portion 25 inside the opening 24,
This is held down by a spout member that is fitted or screwed into the bottle mouth 24, and after filling the content liquid, the bottle is turned upside down and the ball 22 at the bottom of the bottle is lowered to the bottle mouth 24, and the internal pressure of the bottle 23 causes the ball to 22 was pressed into the hole 30 of the ring-shaped packing 21 to seal it. In the case shown, the spout member 20 is connected to the bottle 2.
A protrusion 28 on the inside of the hanging wall 27, which is formed to hang down to the position of the bead 26 of No. 3, engages with a protrusion 29 on the outer periphery of the bottle spout 24 and is fitted into the bottle spout. The ball 22 is crimped to the lower end of the hole 30 of the gasket 21 due to the positive pressure inside the bottle during sealing. When opening the bottle, this ball 22 is pushed down with a bottle opener.

The problem to be solved by the invention The invention consists of a ball and a ring-shaped gasket enclosed in a bottle with a narrowed neck, or
When a conventional sealing body consisting of a spout member 20, a ring-shaped packing 21, and a ball 22 as shown in FIG. After filling the beverage, as described above, turn the bottle upside down, let the ball sink, and use the gas pressure inside the bottle to press the ball against the gasket at the mouth, or pour the beverage with the bottle upside down. After injection filling, a process is required in which the balls that have sunk into the mouth of the bottle are pressed against the packing by the gas pressure inside the bottle, and the bottle is returned to its original position. This complicated the bottler's production process of filling, sealing, packaging, and shipping, and was preventing lines from increasing speed.

Therefore, there has been a long-awaited development of a sealing body for so-called ramune bottles that relies on traditional glass balls but does not require the bottles to be inverted on a conveyor for sealing.

In addition, conventional seals are designed with the assumption that the bottle will be used repeatedly, but bottles with balls sealed in them may be damaged due to collisions between the balls when cleaning the bottle, etc.
The inner surface of the bottle is damaged, and as a result, the strength of the bottle is extremely reduced, leading to frequent explosions of ramune bottles in the past.

Therefore, there has been a long-awaited development of a sealing body that has the above-mentioned features and does not require repeated use of the bottle, or rather does not allow repeated use.

Means for Solving the Constituent Problems of the Invention The present invention solves the above-mentioned problems, and includes a protrusion on the inner circumferential surface that engages with a protrusion on the outer periphery of the bottle mouth and a protrusion that engages with a packing member described later. It has an outer cylindrical wall with an outer cylindrical wall and an inner cylindrical wall whose lower end is pressed against the upper surface of the packing member. a cylindrical portion whose peripheral edge has a flange portion that engages with a protrusion on the inner peripheral surface of the outer cylinder wall, and whose lower inner peripheral edge is a corner portion; , a carbonated beverage bottle comprising a packing member consisting of a skirt portion with a lower end projecting inward, and a ball having a diameter larger than the inner diameter of the cylindrical portion of the packing member and held by the skirt portion. Concerning the envelope.

Function In the sealing body of the present invention, the packing member is integrated with the spout member by engaging the periphery of the flange portion of the cylindrical portion with the protrusion provided on the inner circumferential surface of the outer cylinder wall of the spout member. Also, if the ball is press-fitted from below into the lower end of the lower skirt part of the packing member, which has an inner diameter that is slightly smaller than the diameter of the ball, the inner diameter of the skirt part is larger than the diameter of the ball except for the lower end, so it will fit into the skirt part. The ball is held by the lower end. These three are thus integrated. This is pressed onto the mouth of the bottle filled with the internal solution from above all at once. When the sealer is crimped to the bottle opening in this way, the ball is held by the packing member and is at or close to the sealing position, so it is crimped to the corner of the inner periphery of the lower end of the cylinder by the internal pressure of the bottle. Then, the bottle is immediately sealed, and as in the past, after fuel injection, the bottle is placed upside down on a conveyor and the ball at the bottom of the bottle is brought to the bottle mouth and crimped to seal it, or the bottle is placed upside down in advance. There is no longer a need to inject drinks.

In the present invention, the inner peripheral edge of the lower end of the tube portion 10 is formed into a corner a, but it is difficult to form a glass ball into a perfect sphere, and there is a dimensional variation of about 1 mm. This is because even if such a ball is compressed by the internal pressure of the container, a perfect seal is achieved.

As mentioned above, the sealing body of the present invention differs in its structure from the conventional sealing body, and therefore, the method of use thereof is also different.

In the case of the conventional sealing body shown in Fig. 2, a ball is inserted into the bottle in advance, and immediately after pouring the beverage into the bottle, the bottle is turned upside down to sink the ball, and the internal pressure of the bottle presses it against the seal. Because the beverage is consumed by dropping the ball and becomes an empty bottle with the ball inside, it can be collected, washed, and reused through the same process. In fact, it has been used repeatedly in this way.

In contrast, in the sealing body of the present invention, the spout member 1, the packing member 2, and the ball 3 are integrated in advance, and the ball 3 is mechanically press-fitted into the skirt portion. Therefore, after the ball 3 is dropped, that is, after the bottle is opened and the beverage is consumed, even if the bottle is filled with a beverage and turned upside down as in the conventional sealing body, the ball will again be skirted by the gas pressure. Since it does not fit into the part 11, it cannot be sealed, and the bottle cannot be used repeatedly. Due to the nature of glass, the strength of bottles decreases dramatically after one use, but according to this invention, bottles become one-way and only new bottles are used, reducing the risk of bottle explosions. will be resolved.

Although it is physically possible to remove the seal of the present invention from the bottle mouth after use and reuse it, this is not economically possible at all.

Embodiments The present invention will be explained in detail with reference to embodiments in the drawings.
The sealing body of the present invention includes a spout member 1 and a packing member 2.
and ball 3. The spout member 1 has a cylindrical shape, and the upper ends of an outer cylinder wall 4 and an inner cylinder wall 5 consisting of double inner and outer cylinder walls are connected to form a spout edge 1a. A protrusion 6 is provided on the inner circumferential surface of the outer cylinder wall 4 extending to the position of the bead 15 of the bottle, and engages with a protrusion 8 provided on the outer circumference of the bottle opening 7. Above the projection 6 on the inner peripheral surface of the outer cylindrical wall 4, there is further a projection 9, which has a peripheral edge 13 engaged with a flange portion 12 extending from the upper part of the cylindrical portion 10 of the packing member 2. The packing member 2 includes a cylindrical portion 10 and a skirt portion 1.
1, and from the top of the cylindrical part 10 there is a flange part 1.
2 is widened, its peripheral edge 13 engages with the protrusion 9 of the spout member 1 as described above, and the lower outer peripheral surface is pressed against the inner peripheral surface of the bottle mouth. The inner diameter of the cylindrical portion 10 is smaller than the diameter of the ball 3, the inner diameter of the skirt portion 11 is large enough to fit the ball 3, and the lower skirt portion 14 protrudes slightly inward to hold the ball 3. . Since the packing member 2 and the ball 3 have such a dimensional relationship, when the bottle is sealed, the ball 3 receives pressure in the direction of the arrow A and is strongly pressed against the inner lower edge of the cylindrical portion, so that the seal is completely sealed at this corner a. It will be done. When pouring out the liquid content, when the ball 3 is pressed against the lower end of the lower skirt portion 14 by tilting the bottle, there is a risk that the outflow of the liquid content may be obstructed. This point is similar to the case of the conventional sealing body shown in FIG. As a result, the ball stops between these two protrusions even when pouring out the liquid content, so that the outflow of the liquid is not obstructed. Therefore, it is preferable to use a bottle having the same shape as the so-called ramune bottle in the sealed body of the present invention.

Further, in the embodiment shown in FIG. 1, there are annular recesses 16 and 17 between the outer cylinder wall 4 and the inner cylinder wall 5.
Depending on the material of the spout member, the number of such recesses may be one if there is no problem with strength, elasticity, etc.

Spout member 1, packing member 2 and ball 3
These three are pre-integrated and fit into the bottle mouth, but in order to integrate them, the ball 3
The packing member 2 is placed on top of the packing member 2, and the spout member 1 is placed on top of the packing member 2, and the spout member 1 is pressed from above. Of course, for the spout member 1 that is upside down, the gasket member and ball 2 that are upside down
The person may be crimped. In addition, in this invention,
A protrusion and a protrusion are not essentially different, and a protrusion and a protrusion can be substituted for each other.

Effects of the invention According to the invention, after filling the bottle with liquid, the ball is brought into pressure contact with the mouth of the bottle, especially the lower end of the packing member by turning the bottle upside down, etc. This eliminates the most troublesome step in the bottling process.

Furthermore, it is no longer necessary to sequentially attach the ball, packing member, and spout member to the bottle in the pre-filling stage, as was the case in the past, and sealing can now only be done once after filling the bottle. . Therefore, the effect of simplifying the bottling process according to the present invention is extremely large.

Furthermore, since the seal of the present invention is based on the assumption that the bottle will not be used repeatedly, it is possible to prevent bottle explosion accidents.
