JP4264848B1 - Carbonated beverage bottle container - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a bottle container for carbonated drinks capable of preventing liquid leakage from an opening due to a large amount of carbon dioxide gas generation even when a lamb ball drops to the bottom of the container at the time of opening.
A constricted portion (11) is formed by recessing a side surface of a ramune bottle body (1) from both sides inward. The constricted portion 11 has a substantially 8-shaped cross section inside the bottle, with the central portion serving as a blocking portion and both sides serving as communicating portions. The Ramune sphere 3 falling by opening the bottle once collides with the blocking portion, and then slowly passes through the communicating portion and falls to the bottom of the bottle. Thus, since it falls after cushioning by the constriction part 11, even if it is a bottom ball system, foaming of carbonated drinks can be suppressed.

Description

The present invention relates to a carbonated beverage bottle container, and more particularly to a so-called ramune bottle whose opening is sealed with a spherical plug member.

  Traditionally, ramune beverages have been sold in bottle containers called so-called ramune bottles. The ramune bottle is a glass jar containing a glass sphere (ramune sphere) that is a stopper member inside, and the ramune sphere is pressed against the cap opening by the pressure of carbonic acid of the ramune beverage filled inside and sealed. Is of a unique structure.

  Opening is performed by pushing the ramune sphere into the container and opening the opening of the bottle. Carbon dioxide gas is blown out by the impact of the ramune sphere pushed inside dropping inside the ramune beverage. For this reason, conventionally, a stenosis is formed at a predetermined position from the opening of the ramune bottle, and the fallen ramune sphere is stopped at the stenosis. As a result, the ramune sphere falls to the bottom of the bottle and prevents a large amount of carbon dioxide from being blown out or leaked.

At present, the containers of ramune beverages have been shifted from glass bottles to resin bottles such as PET. However, the flavor, tradition, and ramune character of ramune beverages, which are traditional Japanese beverages, increase the product value. Traditionally, bottles that are sealed with a sphere and opened by dropping the ramune sphere inside the bottle have been used. (See Patent Documents 1 and 2)

  However, the above-mentioned lambéne bottle that stops the ramune sphere at the stenosis part needs to form a stenosis part that is so deep that the ramune sphere cannot pass through, so a manufacturing process is required to maintain the strength of the stenosis part. Was not easy.

  Furthermore, the above-mentioned ramune bottle has a structure in which the stenosis portion is narrow and the ramune sphere is located above the stenosis portion, so that the ramune beverage is difficult to pass through the stenosis portion in the manufacturing process of filling the ramune beverage into the bottle. It was an impediment to improvement.

  Further, since the ramune sphere is stopped at the upper part of the constricted portion, there is a drawback that the ramune sphere falls to the opening as soon as it is swung downward. The ramune bottle is formed with a ball stopper for preventing this, but since it has a shallow protrusion shape, it is easily removed.

  In addition, the constricted portion and the ball stopper are formed by denting the side surface of the bottle to the inside, so that they always appear in the outer appearance and restrict the degree of freedom of the outer shape of the ramune bottle. For example, even when the upper part of the bottle has the same diameter as the lower part like the ramune bottle of Patent Document 2, the swelled part is deep and the bulge of the upper part of the bottle becomes extreme, and the appearance is not beautiful.

  Then, this invention aims at providing the bottle container for carbonated drinks which solved the said subject by making it the container shape of the bottom ball system which does not stop a spherical stopper member in a constriction part.

In order to solve the above problems, a bottle container for carbonated beverages of the present invention has a bottle main body having an opening at the upper end and a spherical stopper member that seals the opening and falls into the bottle main body by pushing, In the carbonated beverage bottle container, between the opening portion and the bottom portion of the bottle body, a blocking portion that temporarily receives the drop of the spherical plug member and a communication portion that is an opening through which the spherical plug member can pass. The cushion part which becomes is characterized by being formed.
Further, the present invention is characterized in that the cushion portion is formed by a constricted portion in which a side surface of the bottle body is deformed to the inner surface side.

  Further, according to the present invention, the constricted portion deforms the opposing side surface of the bottle body to the inner surface side, and the size of the gap between the two opposing portions is smaller than the diameter of the spherical plug member at the central portion, The outer peripheral portions on both sides are characterized by having a shape larger than the diameter of the spherical plug member.

  If the bottle container for carbonated drinks is used, even if a spherical plug member, which is a so-called ramune sphere, is pushed into the container at the time of opening, there is little generation of carbon dioxide gas due to the impact of dropping, so liquid may spill from the opening. Few.

In addition, even when the constricted portion is formed by deforming the bottle side surface to the inner surface side, since the communication portion through which the spherical plug member passes is provided, the overall degree of stenosis is small, manufacturing is easy, and The bottle container can be efficiently filled with a carbonated beverage.
Moreover, this invention is characterized by the maximum outer diameter of the upper part rather than the said cushion part of the said bottle main body being the same as the maximum outer diameter of the lower part rather than the said cushion part.
As a result, the rolling stability at the time of rolling and discharging by a vending machine is improved, and unattended sales other than in-store sales are also possible.
Moreover, the present invention is characterized in that the spherical plug member is made of a resin having a specific gravity of 1 or more.
Furthermore, the present invention is characterized in that the spherical plug member is provided with a design such as a picture, a character, or a pattern.

  As a result, the spherical stopper member, which is a so-called ramune sphere, can collide with or pass through the cushion part, and the upper space and the lower space can be rolled up and down across the cushion part. It is possible to realize a carbonated beverage bottle container that can be enjoyed even after.

  As described above, by providing a cushion part in the middle of the bottle as described above, even when the spherical plug member is pushed into the container at the time of opening, the spherical plug member once stopped at the blocking part of the cushion part. After that, it slowly passes through the communication part and falls to the bottom. Thereby, it is possible to realize a bottle container for container-packed carbonated drinks that generates little carbon dioxide due to the impact of dropping and does not spill liquid from the opening.

  Further, the bottle container for carbonated drinks of the present invention eliminates the need to form a deep constriction that does not allow the spherical stopper member to pass through the container body, making it easy to maintain the strength of the bottle container and producing a container-packed beverage. In the process, the filling rate of carbonated beverages can be increased, and productivity can be improved.

A ramune bottle according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a ramune bottle, and FIG. 2 is a longitudinal sectional view. The bottle body 1 is made of polyethylene terephthalate (PET) and has an opening 10 at the upper end. Further, a constricted portion 11 is provided slightly above the center of the bottle body 1. The opening 10 has a substantially cylindrical shape, and an external thread is formed on the outer peripheral surface. The cap 2 is screwed to the male screw.
In addition, the upper part 12 of the bottle body 1 has three dimples 15 as a design like a Ramune bottle.

  The cap 2 has an outer cylinder 21 and an inner cylinder 22 that are connected to each other on the upper surface, and an upper center portion is open. This opening 20 becomes a drinking mouth. The outer cylinder 21 of the cap is made of polypropylene, and the inner cylinder is made of low density polyethylene. A female thread is formed inside the outer cylinder 21 of the cap 2, and this female thread is screwed with the male thread of the opening 10 of the bottle body 1. Moreover, two ribs along the circumference are formed on the inner wall surface of the inner cylinder 22, and the Ramune sphere 3 that is a spherical plug member is held between the two ribs. The structure of the cap 2 is described in detail in Japanese Patent Application Laid-Open No. 2004-051205 and the like of the present applicant.

  FIG. 3 is an AA end view showing a cross section of the constricted portion 11. As for the bottle main body 1, in the constricted part 11, the width | variety on either side narrows and the width | variety of front and back is hardly narrowed. In the cross-sectional view of FIG. 3, the constricted portion 11 has an approximately eight shape that is long in the front-rear direction, and includes a front opening 111 and a rear portion (FIG. 3) formed on the front portion (lower portion in FIG. 3) side of the bottle body. As shown in FIG. 4, the rear opening 112 formed on the upper side in FIG. 4 has a size that allows the Ramune sphere 3 to pass therethrough. Then, a narrowed portion 113 narrowed to the left and right widths is formed in the center so that the ramune sphere 3 cannot pass through so as to separate the front opening 111 and the rear opening 112. Further, the narrowed portion 113 is formed by deforming the bottle main body 1 to the inner side, so that an inclined portion 14 is generated in the bottle main body 1. The narrowed portion 113 and the inclined portion 14 correspond to the blocking portion of the present invention, and the front opening 111 and the rear opening 112 correspond to the communicating portion of the present invention.

  There is no limitation on the shape and size of the communicating part as long as the ramune sphere 3 can pass through. A preferable shape of the communication portion is similar to that of the ramune sphere 3, and its area is preferably about 1.05 to 2.0 times the cross-sectional area of the ramune sphere 3. If it is 1.05 times or less, the ramune sphere 3 is difficult to pass. If it is 2.0 times or more, the ramune sphere 3 falls directly without being cushioned by the blocking portion, or the ramune sphere 3 opens during drinking. This is because the possibility of returning to the unit 10 is increased.

  With this structure, as shown in FIGS. 5 (A) and 5 (B), the ramune sphere 3 that has fallen from above due to opening is once suspended on the inclined portion 14 or the central portion 113, and then the previous stop. It falls into one of the opening portions of the opening portion 111 or the rear opening portion 112, passes through the constricted portion 11, and falls to the bottom of the bottle body 1. Thus, since the ramune ball 3 is cushioned and dropped once or several times at the constricted portion 11, the falling speed and the impact of the fall can be reduced, and the foaming of the carbonated beverage that is the content is suppressed. Can do.

  In addition, the constricted portion 11 does not hold the ramune sphere 3, but is cushioned and then dropped to the bottom. Therefore, the constricted portion 11 may be a narrow stenosis that allows the ramune sphere 3 to pass except for the constricted portion 113. It is not necessary to make the entire portion 11 narrow enough to prevent the Ramune sphere 3 from passing through. For this reason, while maintaining the intensity | strength of this constriction part, in the manufacturing process of a bottled carbonated drink, when filling a carbonated drink in a bottle, filling to the lower part 13 of a bottle becomes easy, and manufacturing efficiency can be improved. It becomes possible. Moreover, the freedom degree of the external appearance design of a bottle becomes high.

  If the drinker drinks from the right or left side of the bottle, the ramune sphere 3 that has fallen to the bottom is less likely to be blocked by the constricted portion 113 of the constricted portion 11 and return to the opening portion 10, and the ramune ball 3 during drinking. The annoyance that the opening 10 is closed by the sphere 3 is reduced.

Moreover, the upper part 12 and the lower part 13 of the bottle main body 1 partitioned by the constricted part 11 have the same maximum diameter. In general, the upper diameter of the ramune bottle is often smaller than the maximum diameter of the lower part. However, in this embodiment, the constriction of the constricted portion 11 is loose enough to allow the ramune sphere 3 to pass through, so that the design is impaired. The maximum diameter of the bottle upper part 12 can be made the same as that of the lower part 13. By making the maximum diameters of the bottle upper portion 12 and the bottle lower portion 13 the same, the sales suitability by the vending machine is improved. That is, when stacked horizontally on the rack in the vending machine, it is straightly stacked without tilting, and when it rolls to the product outlet, it rolls straight without bending.
The position of the constricted portion 11 is preferably about 80 to 120 mm in the case of a bottle having a capacity of 250 ml and a height of 180 mm.

  FIG. 6 is an AA end view showing another embodiment of the constricted portion 11. In this embodiment, the constricted portion 11 has a substantially keyhole shape in which a circle and a rectangle are combined. The narrowed portion 115 formed on the front part (lower part in FIG. 4) side of the bottle body 1 has a rectangular shape with a width that the Ramune sphere 3 cannot pass through, and the opening part 116 formed on the rear part (upper part in FIG. 4) side. As shown in FIG. 7, the opening is large enough to allow the Ramune sphere 3 to pass through.

  With this structure, as shown in FIG. 8, the Ramune sphere 3 that has fallen from above due to the opening is stopped on the inclined portion 14 or the constricted portion 115 above the constricted portion 115, and thereafter the rear opening portion. It goes around 116 and passes through the constricted part 11 and falls to the bottom of the bottle body 1.

  With this shape, when the drinker drinks from the front of the bottle, the ramune sphere 3 that has fallen to the bottom is blocked by the constricted portion 115 of the constricted portion 11 and does not return to the opening 10. Drinking is possible.

As the Ramune sphere 3 that is a spherical plug member, a glass sphere can be used as in the conventional case. Also, resin balls such as PET (polyethylene terephthalate) or polystyrene may be used. The specific gravity of PET is about 1.27 to 1.40, and the specific gravity of polystyrene is about 1.05 to 1.07, which is closer to 1 than glass (specific gravity of about 2.5). For this reason, by using these resin spheres as the ramune sphere 3, the ramune sphere 3 slowly falls in the carbonated beverage at the time of opening, and foaming due to impact can be reduced.
Further, when PET is used for the bottle body 1, if a PET lamb sphere 3 is used, it can be separated and recycled while the ramune sphere 3 remains in the bottle body 1.

  FIG. 9 is a diagram illustrating an external appearance example of the ramune sphere 3. As described above, the ramune sphere 3 may be provided with an appearance design such as a picture, a character, or a pattern. By applying the appearance design to the ramune sphere 3 in this way, it is possible to enjoy watching the ramune sphere 3 falling while rotating at the time of opening, and the ramune sphere 3 inside the bottle body 1 after drinking. You can enjoy rolling.

In the above-described embodiment, the shape of the inner surface of the constricted portion is exemplified by a substantially 8-shaped shape and a substantially keyhole shape. However, the shape of the constricted portion is not limited to the above as long as it has a blocking portion and a communicating portion. The cushion portion of the present invention is not limited to the constricted portion, and may be formed by inserting a plate (so-called baffle plate) or the like inside.
In addition, in this embodiment, although this invention was demonstrated as a bottle for carbonated drinks, such as a ramune drink and a cider, you may apply the bottle of this invention to another container for drinks.
