Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to improvement of a container for storing carbonated drinking water such as draft beer.

<Prior Art> As a general container of this kind, for example, a commercial beer storage container as shown in FIG. 8 is known.

In the figure, a storage container 81 stores draft beer in a stainless steel main body 82 having a rounded corner and having an oval longitudinal cross section, and a special structure of a hermetically-sealed opening provided in the upper portion of the main body 82. By attaching a freely attachable / detachable connector member (not shown) to 82a, carbon dioxide gas from a gas cylinder (not shown) communicating with the connector member is filled into the main body 82, while the main body 82 is also filled with carbon dioxide gas. The stored draft beer is used by pouring it out from the discharge port of the connector member.

The main body 82 has a protective member 83 having a substantially cylindrical outer peripheral side wall.
The main body 82 is fixed to the inner peripheral wall so as to be enclosed, and the entire body is protected by the protect member 83.

The protect member 83 mainly prevents damage to the main body 82 due to contact when the storage container 81 is carried, and has a plurality of gripping holes 83a in the upper part for facilitating carrying.

Here, the main body 82 has a roundness without corners in order to maintain the internal pressure of the main body 82 at a high value and further to enable good cleaning to every corner when cleaning the inside of the main body 82 when refilling draft beer. It has a shape.

<Problems to be Solved by the Invention> By the way, in order to secure the strength of the main body 82, it is necessary to maintain the thickness of the stainless plate at a predetermined value or more. Even if the protective container 83 is provided to reinforce and protect the outer peripheral side wall of the main body 82 as in the above-described conventional storage container 81, naturally there is a limit to reducing the plate thickness.

However, increasing the thickness of stainless steel also increases the weight, which is disadvantageous in terms of portability such as portability. This type of storage container 81 is an actual condition in which the main body 82 must be filled with draft beer and carried in large amounts during transportation and storage. Therefore, the increase in the weight of the storage container 81 as a whole is extremely difficult to handle. bad.

Further, since the conventional storage container 81 is extremely high compared to the bottom area, it cannot be transported in a state where a plurality of storage containers 81, 81 are stacked. For this reason, even if the locking member such as the concave-convex portion corresponding to each of the upper end portion and the lower end portion of the protect member 83 is provided, the possibility of tipping over during transportation is still extremely high, which is disadvantageous in handling.

Then, even if the height of the storage container is lowered to increase the stability, in this case, the disadvantage that the storage amount is decreased occurs, but even if the bottom area is increased to increase the stability, In this case, the storage space for consumers is particularly inconvenient, which is not suitable for the actual situation.

Furthermore, this type of storage container 81 is particularly used for transportation and storage between wholesalers and retailers, and it is rare that the storage container 81 alone is transported. Plastic storage container 91 for storing bottled beer (9th
(See the figure) is usually transported at the same time. For example, a wholesaler may sell one retailer three storage barrels 81
It is as if 10 bottles of bottled beer container 91 were delivered at the same time.

Here, the bottle beer storage container 91 will be described with reference to FIG. 10 as well. For example, a plastic storage container 91 for storing 20 bottles of beer is provided with a partition 92 for 20 bottles of beer and has an upper end. A locking projection 91a and a locking recess 91b, which correspond to the peripheral edge and the lower edge, respectively, are provided so that a plurality of storage containers 91 can be stacked for transportation and storage.

Here, the above-mentioned difference in shape between the storage container 81 and the storage container 91 is also extremely disadvantageous, which is bothersome for transportation and storage by the trader and the consumer.

Since it is the actual situation as described above, conventionally, in terms of handling the storage container, it is light in weight and easy to carry, and the shape which is easy to carry makes it easier to carry,
Moreover, it is generally desired by traders to provide a storage container that is advantageous in terms of storage, especially in space.

The present invention has been made in view of the above strong demands, and an object of the present invention is to provide an improved carbonated drinking water storage device that is extremely advantageous for transportation and storage by trader users.

<Means for Solving the Problem> Therefore, the present invention provides a carbonated drinking water storage device, which is a storage box made of a synthetic resin having a substantially rectangular parallelepiped shape having a predetermined width, depth, and height, and a storage box of the storage box. A flat metal spherical shell for storing carbonated drinking water, which is stored and supported in contact with a predetermined portion of the inner bottom wall surface and a predetermined portion of each of the four side wall inner wall surfaces, and at least the entire upper surface of the storage box A locking portion that is opened over the entire length of the bottom wall of the storage box and that locks with the upper end of the peripheral edge of the opening of another storage box is provided, and the maximum height of the spherical shell is stored in the storage box. The size is set to be slightly shorter than the depth of the box, and the spherical shell is detachably received and supported in the storage box.

<Operation> With the above configuration, since the spherical shell is housed and protected in the storage box, it is not necessary to increase the plate thickness of the spherical shell, and therefore the increase of the plate thickness causes a problem in terms of weight and manufacturing. Since it is possible to stack the storage boxes with high stability while avoiding this, it is possible to greatly improve usability in terms of transportation and storage, while using it to transport and store more bottled beer, etc. It can be transported and stored together with a plastic storage container, and the usability can be further improved.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a storage container 1 as a carbonated drinking water storage container for storing draft beer for business uses a shell 2 as a spherical shell for storing draft beer, and a storage box for detachably storing and supporting the shell 2. Case 3 and.

The case 3 made of synthetic resin has an upper surface opened over the entire surface, and for example, the width is approximately the same as the width of the storage container 91.
Moreover, the depth is also configured to have substantially the same size as the depth of the storage container 91. Here, the height of the case 3 is predetermined to be slightly deeper than the shell 2 when the shell 2 is completely housed in the case 3 according to the height of the shell 2 as described later. Composed of dimensions.

Reference numeral 3a is a stepped portion provided as a locking portion provided on the peripheral portion of the bottom wall of the case 3, and is configured to be locked on the peripheral upper end portion of the upper surface opening of another case 3 as shown in FIG.

In addition, 3b is a long slot for grasping opened in each side wall upper part of four sides of case 3.

On the other hand, for example, the stainless steel shell 2 is formed into a generally elliptic spherical shape, and is provided with a specially-designed sealed opening 2a at the upper part,
The structure for opening and closing the opening 2a via a connector member (not shown) is the same as the conventional example. Regarding the dimensional relationship of the shell 2, the major axis of a portion having the maximum cross section in the horizontal cross section in the horizontal direction with respect to the upper surface of the case 3 is substantially the same as the inner dimension of the lateral width of the case 3, and the minor axis of the case 3. The height is substantially the same as the inner dimension of the depth, and the height from the lowest position of the shell 2 to the upper end of the opening 2a is slightly shorter than the depth in the case 3. Further, since the shell 2 is housed and supported by the case 3 and protected, the plate thickness of the stainless steel of the shell 2 is as thin as possible.

According to such a configuration, draft beer can be stored in the relatively lightweight shell 2, and draft beer can be poured out of the shell 2 via the connector member as necessary.

Now, for example, when transporting or storing two barrels of storage containers 1, 1, as shown in FIG. 2, mount the step portion 3a of the upper case 3 on the upper edge of the peripheral edge of the lower case 3. Since they can be stacked stably by placing them, they can be easily handled during transportation and storage. In particular, when storing a large number of storage containers 1, not only two layers but also the effective use of the upper space by stacking several layers is sufficiently possible, which is not only convenient for handling but also in terms of space. It can be extremely advantageous.

Moreover, since the width and depth of the case 3 of the storage container 1 are configured to be substantially the same as the width and depth of the storage container 91 for bottled beer, the storage container 1 and the storage container 1 are both transported and stored. 91 can be stacked together, which is very advantageous in terms of handling and space.

Furthermore, since the storage container 1 and the storage container 91 have substantially the same width and depth as described above, for example, a container operator of a trader can handle both containers 1 and 91 with substantially the same feeling. Compared with handling the storage container 81 and the storage container 91 having completely different shapes separately, there is also an advantage that the work can be performed easily.

Further, since the metal shell 2 is housed and supported in the synthetic resin case 3, there is also an advantage that the abutting portions of the shell 2 and the case 3 are less likely to be damaged due to a large difference in hardness between them.

FIG. 3 shows a second embodiment.

This is a storage container 11 in which the shell 12 has a shape closer to a rectangular parallelepiped than that of the first embodiment, and each corner has roundness. The major axis and minor axis of the cross section having the maximum cross-sectional area of the shell 12 are substantially the same as the lateral width and the depth dimension of the case 3, respectively, and the shell 12 is detachably housed and supported in the case 3. The same as in the first embodiment.

According to this embodiment, the same effect as that of the first embodiment is obtained, and the shell 12 can be stored in the case 3 relatively stably when compared with the first embodiment.

In FIG. 4 showing the third embodiment, a ring member 24 as a positional deviation suppressing portion for suppressing positional deviation of the shell 2 is provided at a portion of the inner surface of the bottom wall of the case 23 which is in contact with the bottom portion of the shell 2. A storage container 21 including a case 23 provided is shown.

According to this embodiment, the shell 2 housed and supported in the case 23
The vertical movement in the major axis direction or the minor axis direction can be more effectively suppressed, and the effect that the handleability can be further improved as compared with the above-mentioned embodiment can be obtained.

In FIG. 5 showing the fourth embodiment, a skirt member 34 as a positional deviation suppressing portion for suppressing positional deviation of the shell 32 is provided at a contact portion of the bottom of the shell 32 with the inner surface of the bottom wall of the case 3. 1 shows a storage container 31 with a shell 32 provided.

This embodiment also has substantially the same effect as the third embodiment.

FIG. 6 showing the fifth embodiment shows the position of the position shift suppressing portion,
Examples of different shapes and numbers are shown below.

This storage device is provided with a case 43 in which support members 44, 44 are provided as position deviation suppressing portions at respective portions of both side walls of the case 43 which come into contact with both ends of the shell 2 on the long diameter side of the shell 2 and which oppose each other. A container 41 is shown. The support member 44 is, for example, the seventh
As shown in the figure, the shell 2 is in contact with the front end of the shell 2 so as to cover both sides and the lower part.

According to this embodiment, as well as the vertical movement of the shell 2 in the major axis direction,
The position shift of the shell 2 can be suppressed more effectively.

In addition, the difference in the capacity of the storage container, for example, the difference in capacity such as 10l, 15l, 20l, 25l, etc., must be specified by the height of the case according to the height of the shell without changing the width and depth of the case. If this is determined according to the above, there will be no hindrance to the stacking of the storage containers, and the handling will not be impaired.

Further, in each of the above-described embodiments, two types of spherical shells, such as elliptical shells, are shown. However, the present invention is not limited to this, and it is apparent that other flat spherical shells are applied. .

Also, three types of examples have been shown as the position shift suppressing section, but the present invention is not limited to this, and in terms of shape, position, and number,
Although illustration is omitted, it goes without saying that there are other examples that are different.

Further, the locking portion of the storage box is also shown to have the step portion 3a provided on the peripheral edge portion of the bottom wall, but it is clear that the locking portion is not limited to this example.

<Effect of the Invention> As described above, according to the present invention, the carbonated drinking water storage container is detachably accommodated and supported by the metallic spherical shell in the synthetic resin storage box. Since it is configured to be protected, it is possible to stack stably while suppressing an increase in the weight of the entire storage container as much as possible, and it is possible to improve the handleability and greatly improve the usability in terms of transportation and storage. Can be improved.

Furthermore, since the dimensions of the storage box and the spherical shell are set to the prescribed dimensions,
It is possible to transport and store bottled beer etc. in a package with a plastic storage container used for transport and storage, and further improve usability.
