Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a variable capacity container for foods whose capacity increases by heating and cooking, such as puffed foods.

(Prior Art) Conventionally, as a method of heating and cooking puffed foods etc. in a container, the puffed foods, etc. are placed in advance in a container whose capacity will reach its maximum capacity when cooked.
I try to put food in it before the capacity increases. Furthermore, many conventional containers for puffed foods are bag-shaped.

(Problem to be solved by the invention) As described above, if a food that has not yet increased in capacity is placed in a container whose capacity is adjusted to the maximum capacity when puffed food is heated and cooked, there will be a space in the container. If it is a bag container, it is necessary to fold the air part.

In order to solve the above problems, it is possible to use an expandable container with a bellows-shaped container body, but when the lid plate is removed after cooking, the container returns to its original shape before heating. I have a problem trying to go back.

(Means for solving the problem) Therefore, the technical problem of the present invention is to obtain a container for puffed food that does not return to its shape before heating after cooking. The technical means of the present invention to solve the technical problem is that the container body is cylindrical with a bellows-like structure, which is expandable and contractable in the vertical direction, and has ruled lines to prevent expansion and contraction in addition to the regular bellows rules. This is a variable capacity container characterized by being provided with.

(Effect of the invention) According to this technical means, the capacity can be varied between an extended state, that is, a superimposed state, and a contracted state, that is, a stored state, by the bellows of the container body, so the capacity can be varied according to changes in the volume of food. .

Furthermore, the shrinkage prevention ruled lines prevent the container from shrinking once it has been stretched.

(Example) The embodiments shown in the drawings will be described below.

Reference numeral 1 denotes a container body, which is a bellows-shaped cylindrical body and is vertically expandable and retractable.

2, 3, and 4 are the normal ruled lines of bellows, but in this case, ruled lines 5 for preventing shrinkage are further provided.

In the case of a polygonal container, this ruled line 5 is provided so as to cross the bellows ruled lines 2, 3, and 4 of the corner portion 6. Furthermore, when the container body is cylindrical, it is provided in a shape like 5 in FIG.

7 is a cover plate. This lid plate is constructed separately from the container body, but may be constructed integrally as shown in FIG. 3.

The cover plate shown in FIG. 3 has upper stacked plates 8 and 9 on the front and rear sides of left and right lower stacked plates 10 and 11, and the upper stacked plates 8 and 9 are engaged with each other by their engaging pieces 8a and 9a. Figure 3 shows the closed state, and Figure 4 shows the opened state.

Figure 1 shows the invented variable capacity container filled with an appropriate amount of popcorn seeds and oil and then heated in a microwave oven. This is shown in Figure 1C.

If the container main body is only a normal bellows, if the lid plate 7 is removed after cooking, the container will return to the state before heating.

However, according to the present invention, when the container is expanded, the shrinkage-preventing ruled lines 5 act to prevent shrinkage.

FIG. 5 shows a bellows-shaped container with a cylindrical container body. If the container body is a cylindrical bellows container, it is sufficient to insert a shrinkage prevention line as shown in 5. Before heating (C) and after heating (D), the center line will fit inside.

The container body is made of a paper-based material such as oil- and heat-resistant paper, heat-resistant resin-coated paper, or laminated paper, or a plastic-based material such as a heat-resistant plastic film, or a composite product of paper and plastic.

Figure 2 B, C, and D show the positions of the anti-shrinkage ruled lines in the case of polygonal containers, and the anti-shrinkage ruled lines are in contact with the left end or right end of the vertical ruled line 4 of the bellows. Either place it in a position like this, or put it in the middle part as in C.

The container body and the lid plate may be square (rectangular), or may have any polygonal cylindrical shape, circular shape, or a composite shape of a polygonal and circular shape.

[Brief explanation of the drawing]

Figure 1 A, B, and C show the state of the container before heating and after heating. The perspective view of the container, FIGS. 2A, 2B, 2C and 2, shows the positions where the shrinkage prevention ruled lines are provided in the case of a polygonal container. Figures 3 and 4 (a) and (b) are a slope view and a partial view of the proposed container when the container body and lid plate are integrated, and Figures 5 (a), (b), (c), and (d) are a slope view and a partial view of the cylindrical proposed container.
