In FIGS. 1 and 2, reference numeral (1) denotes a plastic outer container having an upper surface opened, and (2) denotes a plastic inner container having an upper surface opened. The inner container (2) can be housed inside the outer container (1), and the inner container (2) is closed by the lid member (3).

The side walls of the outer container (1) and the inner container (2) have substantially the same taper, and an air space is formed between both side walls.

[0032] The outer container (1) has a force S capable of selecting various plastics, for example, acrylic nitrile styrene and polycarbonate.

[0033] When the label is fitted between the outer container (1) and the inner container (2) as described above, the outer container 1 is made transparent or translucent so that the label can be seen from the outer part. It is preferable to use a material.

[0034] Although the inner container (2) is in contact with hot water, it is possible to use various plastics as long as it is heat resistant. For example, heat-resistant polypropylene or polyethylene naphthalate resin. [0035] The outer container (1) has a connecting portion A (ll) formed in a protruding shape on the inner side of the bottom surface portion, and a grounding portion on the outer side of the bottom surface portion for the purpose of preventing slipping. (7) is provided. As the grounding portion (7), there are various forces that can be used, for example, silicone rubber, ethylene-propylene rubber, and nitrinole rubber.

[0036] The inner container (2) has a flange (21) formed at the upper end of the opening. Further, the connecting part B (22) is formed in a body protruding from the bottom part, and the lower end part (23) of the side wall is screwed to the connecting part A (11) and the connecting part B (22). In this case, the outer container (1) is formed so as to extend substantially linearly from the side wall portion so as to substantially contact or actually contact the inner bottom surface portion of the outer container (1). The upper end of the opening of the outer container (1) has a structure that fits closely to the inside of the flange portion (21) of the inner container (2) via the first gasket (4).

[0037] It should be noted that the inner container (2) may be in-mold molded and given a specific design on the outer surface of the side wall, in addition to the plain.

[0038] The first gasket (4) has various forces S as long as it is an elastic material, for example, silicone rubber and ethylene-propylene rubber.

[0039] The connecting portion A (ll) of the outer container and the connecting portion B (22) of the inner container are screwed and locked. At this time, the open upper end of the outer container (1) is connected to the inner container (2). The outer container (1) and the inner container (2) are fixed by closely fitting and fitting to the inside of the flange part (21) via the first gasket (4).

Therefore, a small hole (32) is provided for the purpose of removing excess steam.

[0043] The side walls of the outer container (1) and the inner container (2) of this container have substantially the same taper, and an air layer gap is formed between both side walls. It is possible to force the label (sheet) (6) into the gap of the air layer. Various methods of fitting are possible. For example, the label (sheet) (6) is brought into close contact with the inner peripheral surface of the barrel of the outer container (1) or the outer peripheral surface of the barrel of the inner container. There is a method of fitting the label (sheet) (6) into the gap between the two containers by storing the inner container (2) in (1) and screwing together. This label (sheet) (6) can be made of various materials such as paper. For example, in addition to paper, various materials such as polyethylene terephthalate having relatively elasticity can be used. You can freely change your favorite pictures and photos to print.

[0044] As the instant food that can be stored and eaten in the container, various types of instant foods can be used as long as they can be stored in the inner container (1). Specifically, instant meals, instant wontons and instant soups are possible.

[0045] Among the instant foods, particularly for instant meals, Force S, which is an instant food that can effectively use the container, in this case, a simple packaged refillable instant meal is preferred.

[0046] Specifically, for example, a packaging instant bag described in Japanese Patent Application No. 2006-254247 by the applicant of the present application is suitable. In other words, the technology can restore the bowl, soup and ingredients just by adding hot water like a commercially available instant cup bowl, and it can be used to eat, yet it is different from the instant cup bowl. It is a type of instant packaging that is moved from the package to the container for eating.

[0047] With the instant packaging of this packaging, it is possible to reduce the packaging material to be discarded as much as possible without discarding the cup container.

[0048] As shown in Fig. 3 (a), this packaging instant bag is a packaged instant bag made by evacuating and packing the instant refill instant lump with a soft packaging material, as shown in Fig. 3 (b). Open from the bottom, cover the double container according to the present invention from the top as shown in Fig. 3 (c), turn it over and turn it over as shown in Fig. 3 (d) By taking out the instant lump from the package and storing it in the double container of the present invention, it is possible to eat after adding hot water.

[0049] In particular, when the shape of the instant lumps is adjusted to match the tapered shape of the container of the present application and can be held in the middle as shown in Fig. 4, when hot water is poured into the container, Since hot water can restore the lump from the bottom of the lump, it can be quickly restored. In addition, in the state where the label (6) is fitted, as shown in Fig. 4 (b), the label can be held stably with the force S without causing slack in the label.
