Description

[Detailed description of the device]

[Industrial applications]

 The present invention relates to a combination container for a microwave oven in which an inner box having a flange portion and an outer box having a forehead portion are combined. More specifically, it relates to a structure of a combination container for a microwave oven in which the lower surface of the flange portion of the inner box and the upper surface of the outer box are brought into contact with each other to hold the main body of the inner box inside the outer box.

[0002]

[Prior art]

 The present inventor has previously devised the microwave oven container shown in FIGS. 1 to 3 (Japanese Patent Application No. 61-219236). This microwave oven container is roughly as follows. That is, in the figure, 1 is an outer box, which comprises a main body formed of a bottom plate 3, side plates 4 and a forehead part 5, and a lid part 6 connected to the hinge part of the main body. On the other hand, 2 is an inner box, which comprises a main body composed of a bottom plate 7 and side plates 8, a flange portion 9 extending around the periphery of the main body, and a top plate 10 for sealing the main body. In this microwave oven container, the lower surface of the flange portion 9 of the inner casing 2 and the upper surface of the forehead portion 5 of the outer casing 1 are brought into contact with each other to hold the main body of the inner casing inside the forehead portion of the outer casing. Distribute.

Conventionally, the materials of the inner box and the outer box have emphasized ease of molding and cost, and the inner box 2 is made of metal such as aluminum or iron, or is laminated or coated with synthetic resin. The main body is generally formed by punching out a single sheet. The outer box 1 is made of paper or synthetic resin, or is made by laminating or coating synthetic resin on paper, and it is common to cut, bend and assemble one sheet.

[0004]

[Problems to be solved by the device]

 Therefore, in this type of combination container, a frequent problem is the relationship between the strength of the outer box and the load of the inner box when the contents are filled. While it affects the molding and causes inconvenience in molding, weakening the material of the outer box does not provide sufficient strength to hold the inner box, and the outer box may be deformed during distribution, protecting the inner box. There is a problem that the role of the outer box cannot be fulfilled. If the inner box is made of metal, a discharge phenomenon may occur when heated in a microwave oven, which is dangerous.

The present invention is intended to solve these problems in the combination container. That is, the object of the present invention is a combination container consisting of an inner box made of metal and an outer box made of paper or synthetic resin, in which the above-mentioned problem is unlikely to occur in the outer box, and it is heated in a microwave oven. It is an object of the present invention to provide a novel combination container for microwave ovens in which discharge phenomenon does not easily occur from a metal inner box.

[0006]

[Means for Solving the Problems]

 Therefore, the present invention provides a combination container for a microwave oven in which the lower surface of the flange of the inner box and the upper surface of the frame of the outer box are brought into contact with each other to hold the main body of the inner box inside the outer box. ) The outer box has a flap that is approximately the same length as the inner dimension of its side plate, extends from the inner edge of the forehead, and is bent downward, and (b) the inner surface of the bottom of the outer box and the inner box. A space is provided between the bottom plate and the outer surface of the bottom plate, and (c) the outer box is made of paper or synthetic resin, and (d) the inner box is made of metal. is there. Hereinafter, the present invention will be described in detail with reference to FIGS.

Conventionally, in order to manufacture an outer box, the Y portion (the portion surrounded by the dotted line) was cut off in order to form the forehead portion 5 as shown in FIG. 4, but the outer portion of the combination container according to the present invention was cut off. a box, without ablating portions of the Y from the forehead portion, as shown in Figure 5 illustrates the interior portion of the Y respectively cut into Y _1, Y _2, Y _3, Y _4, which as shown in Figure 6 shown The flaps are bent downwards to form flaps. In addition, in the present invention, the term “paper or synthetic resin” as the material of the outer box includes the one obtained by pasting or coating synthetic paper on paper.

Therefore, the flaps Y ₁ , Y ₂ , Y ₃ and Y ₄ of the outer casing 1 have substantially the same dimension (height) as the inner dimension (height) of the side plate 4 of the outer casing 1. The term “substantially the same” means that the dimensions of the flaps may be slightly longer or shorter than the inner dimension of the side plate 4, or both may have the same dimension, as long as it is not against the object of the present invention. .

That is, the size of each flap may be slightly shorter than the inner size of the side plate 4, because when the flange part of the inner case 2 filled with contents is placed on the forehead part 5 of the outer case 1, Since the load of the inner case 2 is applied to the forehead part 5 of the outer case 1, it is slightly lowered, so that even if the flaps Y ₁ , Y ₂ , Y ₃ , and Y ₄ are a little short, they are sufficient as a reinforcing material. This is because it may act.

Further, the size of each flap may be slightly longer than the inner size of the side plate 4 because the flaps Y ₁ , Y ₂ , Y ₃ , Y _{4 which} are folded downward and contact the inner surface of the bottom plate, respectively. This is because the forehead portion 5 may be fixed by being pushed up and may be in a preferable state as a reinforcing material for the outer case. It should be pointed out that the same dimensions are suitable for both.

Further, the flap may not be able to form the four pieces Y ₁ , Y ₂ , Y ₃ and Y ₄ as shown in FIG. 6 depending on the shape of the outer box. In this case, for example, only the opposing sections Y ₃ and Y ₄ may be used as flaps. The object of the present invention can be sufficiently achieved by using a flap for each of Y ₁ , Y ₂ , Y ₃ , and Y ₄ .

Further, the outer box 1 has a flange portion, the lower surface of which is held in contact with the forehead portion of the outer box to hold it inside the outer box, and between the outer box 1 and the inner surface of the bottom plate. A metal inner box with a gap is suspended. (The shape is similar to that shown in FIG. 2, but not shown in FIGS. 4 to 6)

[0013]

[Action]

 As described above in detail, the outer container of the combination container according to the present invention is made of paper or synthetic resin, and the space X is provided between the outer container and the inner container. When used for a long time, it is possible to prevent the dangerous discharge phenomenon caused by the metal inner box. In addition, a flap, which is approximately the same length as the inner dimension of the side plate, is extended from the inner edge of the forehead part and bent downward with respect to the outer box, so this flap serves as a reinforcing material for the outer box. Therefore, it is possible to support the load of the inner box.Therefore, even when the outer box is made of a conventional material, or when the inner box is suspended from the outer box in a suspended state, the outer box can be sufficiently suspended. Reinforce to prevent deformation of the outer case.

[0014]

[Effect of device]

 Therefore, the combination container for a microwave oven according to the present invention can be safely used when being heated in a microwave oven, and can sufficiently withstand the impact at the distribution stage. Moreover, the inner and outer boxes can be easily formed, and the cost can be reduced. From the above, the product value is significantly improved.
