JPH053160U - Lid material for instant food containers - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a lid material for an instant food container having a display portion capable of visually observing an appropriate time after pouring required for completion of noodles and ingredients stored in the container. [Structure] At least a part of the surface of the base layer A has a ready-to-eat display layer 2c displayed with a thermally foamable ink. After pouring boiling water into the container and closing the lid 2 again,
When a certain predetermined time has passed, the heat of the hot water is transferred to the lid member 2, and when the temperature reaches the bubbling temperature of the heat-foaming ink, the ink bubbles, and, for example, the word "tabegoro" discolors. Along with it, you can know the progress of the aptitude time.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a lid material for an instant food container, in particular, an instant food container housed in a cup-shaped container. Like noodles, pour boiling water into the container when you eat and then close the lid, about 1 to 3 minutes Regarding the lid material used for instant food containers that are left to stand and wait for the completion of noodles and utensils It

[0002]

[Prior art]

  Generally, when eating this type of instant food, after pouring hot water into the container, The neglected time is measured by a clock or depends on the feeling of a person. But watch When using it, measuring the time is troublesome, and when relying on human intuition, the noodles and utensils There are many cases where the rising condition is not appropriate.

[0003]

[Problems to be solved by the device]

  Therefore, the technical problem to be solved by the present invention is to improve the quality of food such as noodles and utensils in the container. To provide a lid material having a display capable of visually recognizing that an appropriate time required for bittern has passed. There is

[0004]

[Means, actions, and effects for solving problems]

  In order to solve the above technical problems, according to the present invention, a lid member having the following configuration is provided. Be done.

[0005]   In other words, this lid material for instant food containers has been generally used in containers of this type. At least a part of the surface of the base layer that is coated with heat-foamable ink It is characterized by having a display layer.

[0006]   If the lid material of this configuration is used for an instant food container, the lid will be placed after pouring hot water into the container. If you close and leave the material, the heat of the hot water in the container is transferred to the lid material, and a certain period of time elapses. Then, when the foaming temperature of the heat-foamable ink is reached, the ink foams, The fact that a predetermined aptitude time has elapsed, that is, visual confirmation of the eating habits of food Can be done.

[0007]   In the above configuration, the heat-foamable ink that constitutes the ready-to-eat display layer is protected. In order to form a transparent display protective layer on top of the base layer and the edible display layer, Is preferred. In this case, the foaming of the heat-foamable ink is performed under the surface protective layer, The foaming pressure also causes the surface protective layer itself to rise and the heat-foamable ink to be emitted. Since the foam changes to a whitish color, the foam can be easily visually recognized.

[0008]

【Example】

  An embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

[0009]   FIG. 1 shows an example of instant food, in which instant ramen is stored in a cup-shaped container 1. In both cases, the lid member 2 having the display portion 2a is adhered to the upper opening of the container 1. There is.

[0010]   The laminated structure of the lid member 2 used in this embodiment is shown in FIG. In the figure Then, in order from the top, the transparent surface protection layer 2b and the heat-foamable insul Eatable display layer 2c, picture print layer 2d, core paper layer 2e, adhesive layer 2f, It is composed of a gas barrier layer 2g, an adhesive layer 2h, and an easy peel adhesive layer 2i. Has been. The ready-to-eat display layer 2c is formed on the display portion 2a.

[0011]   Layers 2d, 2e, 2f, 2g, 2h, 2i are base layers A conventionally known as lid materials of this type. It As the transparent surface protective layer 2b, for example, nitrocellulose having excellent heat resistance is used. A resin layer is preferably used. Heat-foaming ink used for ready-to-eat display layer 2c As for the inner surface, it is possible to bond the transparent surface protective layer 2b in a stable state with good adhesion. It is made by mixing a foaming agent that heats and foams into a base material. For example, a heating type foaming ink based on an acrylic ester resin is desirable. This fever The foaming temperature of foam ink is adjusted by appropriately selecting a known foaming agent to be mixed. can do.

[0012]   The picture print layer 2d is for displaying a so-called general picture Ink is used.

[0013]   Single-sided art paper is preferably used as the core paper layer 2e. Adhesive layer 2f is a gas barrier Layer 2g and core paper layer 2e are adhered to each other. For example, a polyethylene resin layer is preferable. Properly used. Aluminum vapor-deposited foil is preferred as the gas barrier layer 2g. Adhesive layer 2h is for bonding the easy peel adhesive layer 2i to the gas barrier layer 2g. is there. Since the adhesive layer 2i has an easy peeling property, a lid material is used when eating food. 2 can be easily peeled off from the container 1.

[0014]   For example, when eating ramen stored in the container of the above configuration, it is the same as before Then, a part of the lid material is peeled off from the container 1, hot water is poured, and the lid 2 is closed again and left to stand. Then, when the predetermined time has passed, the heat generated from the hot water is generated by the lid member 2 The ink of the ready-to-eat display layer 2c is transferred to the surface of the display layer 2c and is foamed to retain the surface as shown in FIG. It will push up the protection layer 2b. At this time, the heat-foaming ink is initially colored. However, it turns whitish when foaming. Therefore, when the display layer 2c is ready to eat By the color change, it is possible to know the elapse of a predetermined appropriate time. That is, As shown in Figure 1, the word "taboro" appears on the lid in a discolored state. Is.

[0015]   The inventors of the present invention have the above-described configuration and use the Moroboshi Ink Co., Ltd. When tested using the product name "foaming ink", hot water of 95 to 100 ° C was put When left in this state for about 60 seconds, the surface temperature of the lid member 2 becomes 82 to 84 ° C and foaming occurs. occured. As described above in detail, according to the above-mentioned embodiment, the foam of the ready-to-eat display layer 2c is formed. By doing so, you can always know for sure the proper time course, that is, the proper eating habits. There are some significant practical effects.
