Description

Bottle for storing liquid for storing gas-containing liquids {Bottle for gas-contained liquid}

The present invention relates to a liquid storage bottle for storing a liquid containing gas, in particular a liquid storage that can be stably placed on the bottom surface to prevent the external leakage of the gas contained in the liquid and to stand the bottle body It is about mercenaries.

Resin liquid storage bottles are often used to store gas-containing liquids. For example, the gas-containing liquid is a carbonated beverage containing carbon dioxide gas, and the resin liquid storage bottle is a so-called PET bottle.

Conventional liquid storage bottles include a bottle main body having a bottle spout for pouring liquid thereon and a bottle cap detachably screwed to the bottle spout for opening and closing the bottle spout. In the case of a conventional liquid storage bottle, the liquid storage bottle is placed on the bottom surface on which the liquid storage bottle is to be erected in order to store the liquid.

However, in case of storing the gas-containing liquid with the bottle spout upward, the liquid contained in the bottle body by gravity sinks in the lower part of the bottle body, and the gas vaporized from the liquid has a specific gravity more than the liquid. It is small so it collects on the top of the bottle. Therefore, there is a problem in that the gas is slowly leaked into the minute gap between the bottle spout and the bottle cap, so that the gas dissolved in the liquid is not completely preserved.

In order to solve this problem, a method of storing a conventional liquid storage bottle upside down can be considered. In this case, the liquid sinks toward the bottle spout by gravity, and the gas is trapped in the space formed by the liquid surface and the bottle body. Here, since the particles of the liquid are larger than the particles of the gas, it is more difficult for the liquid to leak into the fine gap between the bottle spout and the cap. Thus, if only liquid does not leak, the gas can be preserved intact.

However, in order to store the liquid storage bottle upside down, the external support is required, so in the home there is a way to store in the bottle holder of the refrigerator or to stand in the corner corner of the wall, while in the open air there is a way to stand between the cracks However, this is not always possible due to space limitations, and there is a problem that the liquid storage bottle is liable to fall down.

The present invention has been made to solve the above problems, the object of which is to improve the structure of the liquid to prevent the external leakage of the gas contained in the liquid and to stably stand on the bottom surface to stand the bottle body To provide a mercenary.

In order to achieve the above object, a liquid storage bottle according to the present invention includes a bottle main body in which a liquid containing gas is contained therein and a bottle spout for pouring the liquid at one end thereof, and for opening and closing the bottle spout. And a bottle cap detachably coupled to the bottle spout, wherein the center axis of the bottle spout is located radially spaced apart from the center axis of the bottle body in the radial direction of the bottle body, and at one end of the bottle body, with respect to the bottle spout. The protrusion is disposed at a position spaced apart in the circumferential direction of the bottle body and protrudes in the direction of the central axis of the bottle body, and when the bottle body is erected with the bottle spout located below, The bottle cap and the protruding portion coupled to each other are in contact with the bottom surface on which the bottle is to be erected so that the bottle is erected. Characterized in that configured to be supported by.

As described above, according to the present invention, the bottle cap and the protrusion contact the bottom surface on which the bottle body is to be erected, thereby preventing the external leakage of the gas contained in the liquid and stably at the bottom surface on which the bottle body is to be erected. It is effective to stand up.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a partial cross-sectional view of a liquid storage bottle according to an embodiment of the present invention, Figure 2 is a bottom view of the liquid storage bottle shown in FIG. 3 is a front view when the liquid storage bottle shown in FIG. 1 is placed upside down.

1 to 3, the liquid storage bottle 100 according to a preferred embodiment of the present invention is a bottle for storing the liquid (D) containing the gas (C), the bottle body 10 and the bottle cap 20 is configured to include.

The bottle body 10 is to accommodate the liquid (D) containing the gas (C) therein, it can be manufactured using a synthetic resin, like a conventional liquid storage bottle. The bottle body 10 includes a bottle spout 11 and a protrusion 12.

The bottle spout 11 is provided at one end of the bottle body 10 and is for pouring the liquid D contained in the bottle body 10.

In the conventional liquid storage bottle, the center axis of the bottle spout and the center axis of the bottle main body are coincident with each other. In the present embodiment, the center axis B of the bottle spout is from the center axis A of the bottle main body. The main body 10 is located radially spaced apart.

The protrusion 12 is a portion protruding in the direction of the central axis A of the bottle body. The protrusion 12 is provided at the one end of the bottle body 10, that is, at the end (lower end in FIG. 1) in which the bottle spout 11 is provided.

The protrusion 12 is disposed at a position spaced apart from the bottle spout 11 in the circumferential direction P of the bottle body 10. In the present embodiment, two protrusions 12 are provided, and the two protrusions 12 and the bottle spout 11 are equally spaced from each other along the circumferential direction P of the bottle body 10. And spaced apart from each other to be positioned on each vertex of the virtual equilateral triangle (T).

However, in another embodiment, three or more protrusions 12 are provided, and the three or more protrusions 12 and the bottle spout 11 are along the circumferential direction P of the bottle body 10. They may be disposed at the same angular intervals, and spaced apart from each other to be positioned on each vertex of the virtual polygon.

The bottle body 10 is configured to be erected on the bottom surface (G) on which the bottle body (10) is to be placed in a state in which the bottle spout (11) faces upward. In the present embodiment, a circular rim which is in contact with the bottom surface G on the other end of the bottle main body 10, that is, on the opposite end (the upper end in FIG. 1) on which the bottle spout 11 is provided. The support part 13 is formed.

The bottle cap 20 is to open and close the bottle spout 11, is detachably coupled to the bottle spout (11). In this embodiment, the male screw 14 is formed on the bottle spout 11, and the female screw 24 is formed on the bottle cap 20 to be screwed together.

The bottle 100 for storing the liquid is the bottle cap 20 coupled to the bottle spout 11 and the two when the bottle main body 10 is erected with the bottle spout 11 positioned downward. The protruding portion 12 is configured to be supported (hereinafter referred to as 'three point support') in the state where the bottle body 10 is upright by being in contact with the bottom surface G.

When the bottle cap 20 and the two protrusions 12 are in contact with the bottom surface G, the bottle cap 20 and the two protrusions 12 are in point contact with the bottom surface G, respectively. Preferably configured to However, the term "point contact" herein is not a precise point contact of a mathematical concept and means that the area where the bottle cap 20 and the protrusions 12 come into contact with the bottom surface G is very small in a practical sense.

The 'point contact' may be a method of forming a pointed protrusion (not shown) on the contact portion between the protrusions 12 and the bottle cap 20 in contact with the bottom surface G. The method has the disadvantage of damaging the user's body of the liquid storage bottle 100. Therefore, in the present embodiment, the protrusions 12 and the bottle cap 20, by forming a portion in contact with the bottom surface (G) in a smooth curved shape, such as hemispherical shape as a whole, the protrusions 12 And each of the caps 20 are 'point contact' the bottom surface G, respectively. However, unlike in the present embodiment, even if the contact portion of the bottle cap 20 in contact with the bottom surface (G) is formed in a flat shape, it can of course correspond to the 'point contact' as a whole.

When storing the liquid (D) containing the gas (C) by using the above-described liquid storage bottle 100, as shown in Figure 1 the bottle spout 11 is located in the lower state When the main body 10 is placed upright, the gas C contained in the bottle 10 is trapped in the space formed by the water surface S and the bottle 11 of the liquid D, so that it does not leak to the outside. There is an advantage that can be preserved intact.

On the other hand, when opening the liquid storage bottle 100 to use the liquid (D) or when the bottom surface (G) is sanitary dirty, as shown in Figure 1, the bottle spout 11 is Storage underneath is not appropriate. Therefore, in this case, as shown in FIG. 3, the bottle main body 10 can be erected with the bottle spout 11 facing upward by bringing the support part 13 into contact with the bottom surface G. As shown in FIG. There is an advantage.

In this embodiment, in order to allow the bottle body 10 to stand on the bottom surface G even in a state where the bottle spout 11 faces upwards, a circular border which comes into contact with the bottom surface G is formed. Although the supporting part 13 is formed at the other end of the bottle body 10, three protrusions having a shape similar to the protrusion part 12 formed at one end of the bottle body 10 are provided at the other end of the bottle body 10. Of course, it is also possible to form a support part 13 of the 'three-point support' method in contact with the bottom surface (G).

In addition, through the 'three-point support' there is an advantage that the bottle body 10 can be stably erected not only on the flat bottom surface such as a tabletop, but also on a slightly irregular bottom surface such as an outdoor lawn or gravel field.

Unlike in this embodiment, 'multi-point support' consisting of three or more protrusions 12 and one bottle cap 20 can also be implemented. However, even in this case, since there are three actual contacts coming into contact with the bottom surface G and the remaining contacts are likely to be redundant contacts, the 'multipoint support' is less stable than the 'three point support'. Can be.

In addition, unlike in the present embodiment, it is possible to implement a 'two point support' in which the bottle body 10 is erected on the bottom surface G by using one protrusion 12 and the bottle cap 20. In the end of the one projection 12, the portion in contact with the bottom surface (G) can not be formed in a smooth curved shape, such as hemispherical shape as a whole, but in a shape that is in wide contact with the bottom surface (G) Since it should be formed, there is a disadvantage that the stability as in the 'three point support' method is difficult to expect.

On the other hand, since the 'point contact' is used when the bottle body 10 is placed on the bottom surface G, in this embodiment, the area where the bottle body 10 and the bottom surface G contact. Since it is significantly reduced in comparison with this conventional liquid storage bottle, even when the bottle body 10 is placed on the bottom surface G with contaminants, the contaminants adhere to the bottle body 10 relatively little. There is this.

And, the central axis (B) of the bottle spout is located to be spaced apart from the central axis (A) of the bottle body in the radial direction of the bottle body (10), and at the same time the projection (12) to the bottle spout (11) By being disposed at a position spaced apart in the circumferential direction (P) of the bottle body 10 with respect to, there is an advantage that the liquid contained in the bottle body 10 can be discharged to the outside without accumulating on the protrusion 12. .

Although the present invention has been described above, the technical scope of the present invention is not limited to the contents described in the above-described embodiments, and equivalent configurations modified or changed by those skilled in the art may be described. Obviously, it is not beyond the scope of thought.
