The radially outer portion of the outer peripheral surface of the annular main body 70 serves as a holding portion 74 that is held by the second container by contacting the inner surface of the body portion of the second container.

The cross-sectional shape of the annular main body 70 is not particularly limited, and examples thereof include a circular shape and a rectangular shape, and a circular shape is preferable because the first container and the second container are not easily damaged.
What is necessary is just to set suitably the internal diameter and outer diameter of the annular main-body part 70 according to the outer diameter of the trunk | drum of a 1st container, and the internal diameter of a 2nd container. The inner diameter and outer diameter of the annular main body 70 are within a range where a gap is formed between the first container and the second container, and the support part 72 supports the upper end of the body of the first container as close as possible, It is preferable that the holding portion 74 is as close to the upper end of the barrel portion of the second container as possible. Thereby, heat insulation performance becomes easy to be demonstrated to the upper part of the 1st container.

  The planar view shape of the annular main body 70 is an annular shape in this example, but is not limited to this aspect, and can be appropriately set according to the shapes of the first container and the second container. For example, the annular main body portion 70 may be an annular shape having a rectangular shape in plan view.

  The material of the connection member 2 for containers is not specifically limited, For example, the same thing as what was mentioned by the connection member 1 for containers is mentioned. The connecting member 2 for containers can be manufactured using a known molding method, and examples thereof include a press molding method and an injection molding method.

(Double structure container)
Hereinafter, the aspect which makes the 1st container 100 and the 2nd container 200 with the same shape and magnitude | size made into a double structure container using the connection member 3 for containers of this embodiment based on FIG. 8 is demonstrated.
In the double-structured container 500 using the container connecting member 3, the first container 100 is inserted and fitted into the annular main body 70 of the container connecting member 3 from above. The body part 130 of the container 100 is supported by the support part 72 from the outer side surface 130b side. As a result, the supported first container 100 is prevented from wobbling. In addition, the container connecting member 3 that supports the first container 100 is inserted into the second container 200 together with the first container 100, and the holding portion 74 is connected to the trunk portion 230 of the second container 200. It is held in contact with the inner side surface 230b. In this state, the bottom surface portion 110 of the first container 100 is separated from the bottom surface portion 210 of the second container 200, and a gap 510 is formed between the first container 100 and the second container 200.

  Also in the double-structured container 500, the space 510 is formed between the first container 100 and the second container 200, so that excellent heat insulation performance is exhibited, and the outer second container 200 has Condensation is unlikely to occur. Further, in the double-structured container 500, it is the flange portion 150 that makes a mouth when drinking the beverage stored in the first container 100. Even in the double-structured container 500, since the flange portion 150 of the first container 100 and the flange portion 250 of the container 200 are not overlapped, it is suppressed that the portion where the mouth is attached becomes thick and the mouthfeel becomes poor. .

[Fourth Embodiment]
In the present invention, as in the first to third embodiments, the gap formed between the first container and the second container is separated from the space outside the container in terms of excellent heat insulation performance. A closed space is preferred. Note that the gap formed between the first container and the second container may be an open space connected to the space outside the container. The container connecting member of the present invention may be, for example, the container connecting member 4 illustrated in FIG.

The container connecting member 4 includes a C-shaped main body portion 80 formed of a band-shaped member that forms a C-shape with a part of the ring cut out in plan view. In the container connecting member 4, the radially inner portion of the outer peripheral surface of the C-shaped main body 80 serves as a support portion 82 that supports the first container from the outer surface side of the body portion. In addition, the radially outer portion of the outer peripheral surface of the C-shaped main body portion 80 serves as a holding portion 84 that is held by the second container by being in contact with the inner side surface of the body portion of the second container.
The C-shaped main body portion 80 can adopt the same mode as the annular main body portion 70 except that the C-shaped main body portion 80 has a shape in which a part of the ring is missing.

(Double structure container)
In the double-structured container using the container connecting member 4, the first container 100 is inserted and fitted into the C-shaped main body 80 from above, similarly to the case of using the container connecting member 3. The trunk portion 130 of the first container 100 is supported by the support portion 82 from the outer surface 130b side. In addition, the container connecting member 4 is inserted into the second container 200 together with the first container 100, so that the holding portion 84 is in contact with the inner side surface 230b of the trunk portion 230 of the second container 200. It is held by the second container 200. In this state, the bottom surface portion 110 of the first container 100 is separated from the bottom surface portion 210 of the second container 200, and a gap is formed between the first container 100 and the second container 200. At this time, the gap formed between the first container 100 and the second container 200 is a released space connected to a space outside the container through a portion in which the ring in the C-shaped main body 80 is missing. It has become.

In the double structure container using the container connecting member 4, an excellent heat insulating performance is exhibited by forming a gap formed between the first container 100 and the second container 200, and the outer side. Condensation is unlikely to occur in the second container 200. Moreover, in this double-structured container, similarly to the case where the container connecting member 3 is used, it is suppressed that the portion where the mouth is attached becomes thick and the mouth feel is deteriorated.
Since the double-structure container using the container connecting member 4 is a space in which a gap formed between the first container 100 and the second container 200 is opened, two containers using the container connecting member 3 are used. Compared to the heavy structure container 500, the heat insulation performance is inferior. However, the C-shaped main body 80 of the container connecting member 4 is more easily deformed in the radial direction than the annular main body 70 of the container connecting member 3. Therefore, the container connecting member 4 can easily form a double structure container corresponding to containers of various capacities as compared with the container connecting member 3.

As described above, in the container connecting member of the present invention, the first container is supported from the outer surface side by the support part in a state where the first container is inserted into the second container, and the holding part is By being held in the second container, a gap is formed between the first container and the second container. As described above, when the container connecting member of the present invention is used, two containers are stacked and a gap is formed between the containers, thereby forming a double structure container having excellent heat insulation performance. Therefore, it is possible to easily form a double structure container having excellent heat insulation performance by using two ready-made containers. Moreover, if the connection member for containers of this invention is used, even if the shape and magnitude | size of a 1st container and a 2nd container are the same, a double structure can be formed. Therefore, if there is one ready-made container, a double-structure container having excellent heat insulation performance can be formed using it.
Moreover, in the connection member for containers of the present invention, it is not necessary to manufacture a separate member having a size that covers most of the body portion of the container in order to obtain excellent heat insulation performance, so that the cost is low. Moreover, since the flange part of two containers which form a double structure is not piled up, it can suppress that mouthfeel worsens.

  In the present invention, as in the first embodiment, the holding part is provided below the support part, and the holding part is formed so as to protrude outward from the upper end of the body part of the second container. The aspect in which the groove-shaped fitting part in which a part fits is formed is preferable. If the connecting member for containers of this aspect is used, in the double-structure container, the first container with the second container and the connecting member for containers entirely covered with the body of the first container It is easy to form a gap between the second containers. That is, it is easy to form a double-structured container that exhibits sufficient heat insulation performance up to the top of the first container. Moreover, the double structure of the formed double structure container is also stable. Furthermore, in general, a conventional paper or plastic container is often provided with a flange portion having an opening edge curled in order to improve mouthfeel. In the first embodiment, the flange portion of the container is used as a beverage. It is also advantageous in that it can be used as it is as a part to put a mouth when drinking.

The container connecting member of the present invention is not limited to the above-described one.
The container connecting member of the present invention may be, for example, the container connecting member 2 of the second embodiment in which the third cylindrical portion 62 is not provided. Also in the connecting member for containers, the holding portion is held by the second container by the lower surface of the second projecting portion 60 coming into contact with the upper surface of the flange portion of the second container. In addition, in the container connection member 2, the container connection member in which the third cylindrical portion 62 is not provided corresponds to the container connection member 1 of the first embodiment that is inverted up and down. That is, in an aspect like the container connection member 1 of the first embodiment, the upper and lower support portions and the holding portion can be used in reverse.

  Moreover, the connection member for containers of the present invention is not limited to an aspect that is a band-shaped member that forms a ring as a whole, and depending on the container to be applied, a band-shaped member that forms a ring other than a circle such as a rectangle as a whole The aspect which is.

  Moreover, the connection member for containers of the present invention may be a member for connecting a first container and a second container having different shapes and sizes into a double structure container. For example, in a second container having a quadrangular cylindrical shape with a tapered body that is reduced in diameter from the upper end to the lower end, a cylindrical body having a tapered body that is reduced in diameter from the upper end to the lower end is provided. It may be a connecting member for containers which is a double structure container by overlapping the first container. In such a case, the shape of the connecting member for a container is not necessarily limited to a band shape. For example, the planar view shape of the support portion is circular to match the first container, and the planar view shape of the holding portion is the second shape. It may have a quadrangular shape in accordance with the container, and may have a shape other than a belt shape that is partially different in thickness or the like as a whole.
