Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to tableware such as a paper container into which food such as boiling water or food is put and eaten and drunk.

[0002]

[Prior art]

 Recently, various types of simple foods (instant foods) that are eaten and drank immediately after pouring hot water or after a few minutes have become popular, and paper and plastic containers are used as containers for these simple foods. It is used a lot. In particular, as is well known, as a paper container, one thick paper or a plurality of papers are pasted and the papers are molded into a predetermined shape.

[0003]

[Problems to be solved by the device]

 Since conventional paper tableware is made only of paper, there is a problem that it cannot be held by hand because it is hot immediately after boiling water. In particular, I couldn't hold a paper cup because it was hot right after I put hot tea or coffee in it, so I drank tea or coffee after cooling it down to some extent. It is preferable to drink tea or coffee immediately because it is delicious to make. This also had the same problem with a plastic container without heat insulation.

In addition, while waiting for a few minutes after putting hot water in a container of simple food, a person who does not know that hot water has been put in, such as a small child, is surprised to touch the container or sometimes gets burned. Sometimes. Therefore, in order to solve such a problem, the present invention provides tableware that can visually confirm that hot water is put into a container such as a paper cup, and tableware that can be held by hand immediately after putting hot water.

[0005]

Means and Actions for Solving the Problems The tableware of the first invention is characterized in that a heating foam layer for forming a heat insulating layer which can be held by hand is provided on the surface of the tableware formed in a predetermined shape. To do. The tableware of the second invention is characterized in that it is provided with a heat-foamable layer which is foamed by the heat of the food put in the tableware and visible.

As the heat-foamable layer, for example, a resin composition in which a resin is mixed with a foaming agent that foams at a low temperature is generally used. As the resin and the foaming agent, those generally used are used. As the resin composition, foamed ink (trade name: New Home W211 manufactured by Dainichiseika Co., Ltd.) can be used. When such foamed ink is used, gravure printing is preferable as the printing.

The thickness of the foaming ink for visual recognition is usually not noticeable, and it is preferable that the thickness is such that it is noticeable after foaming. The thickness of the foamed ink for heat insulation is usually sufficiently thin, and it is preferable that the foamed ink is formed so as not to be burned even if it is touched by hand after foaming. Further, the foaming temperature of the heat-foamable layer is preferably around the boundary where human hands can withstand or cannot withstand, or a temperature range several degrees above or below that. In this respect, New Dai Home W211 manufactured by Dainichi Seika Co., Ltd. is suitable.

When hot water is poured into the tableware of the first invention to foam the heating foam layer on the surface of the tableware and a foam layer having excellent heat insulating property is formed, the hot water is poured into even the thin tableware. Immediately after, you can hold the tableware in your hand and eat or drink. In addition, when hot water is poured into the tableware of the second invention, the heating foam layer provided on the surface of the tableware is heated by the hot water to immediately foam, and a visible foam layer is formed. it can.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The first embodiment shown in FIG. 1 is an example of a paper cup, and the paper cup 2 formed in a predetermined shape has an outer peripheral surface including a bottom surface excluding a portion touching the upper lip (excluding the bottom surface). The foam ink layer 3 of the brand name New Dai Home W211 is printed by gravure printing. When hot water of 90 to 100 ° C. is poured into this paper cup 2, the foamed ink layer 3 is heated by the hot water and foams to a thickness of 8 to 9 times, forming a foamed layer.

When foaming occurs depending on the type of foaming ink, the density of the surface becomes rough and the tongue feels bad. Therefore, the foaming ink 3 is not printed on the part touched by the lips. However, if the texture of the tongue does not matter, a foamed ink layer may be formed on the part where the tongue touches. If you want to identify the part of the tableware that you hold with your hands, you can print the shape of your fingers or hands on the surface of the tableware using foam ink that is different in color from the paper cup.

It can be confirmed that the surface state is clearly changed by foaming and that the cup can be held, and in addition, the hot water in the cup does not cool, so that there is a heat retaining effect. . Even if the foaming rate is high and the outside diameter of the cups becomes too large, which makes them unsuitable for stacking and transporting, since there is no foaming from the production of the cups to the stage of shipping and sales Transport efficiency is higher than that of a cup with heat insulation. Therefore, if this cup is used in a vending machine for tea or coffee, it will be easy to take out and convenient.

The second embodiment of FIG. 2 is an example of simple food tableware, in which a thin paper lid 6 is placed on the upper surface of a paper container 5 containing food to seal the food. On the surface of the lid 6, the white foam ink 3 of the brand name New Dai Home W211 is printed, and on the upper surface thereof, the green ink 7 is printed in the shape of a green cross. When hot water of 90 to 100 ° C. is poured into the paper container 5, the foam ink 3 is heated by the steam of the hot water and foams, and the green cross protrudes so as to float upward from the surface of the lid 6. Anyone can see that hot water is in it. On the contrary, when the green cross is printed directly on the surface of the lid 6 and the white foam ink 3 is printed on the entire surface of the lid 6 other than the green cross, the periphery of the green cross floats upward in white, so that it becomes clearer. Can be seen.

Further, as shown in FIG. 3, after the cross is printed with the foam ink 3 on the surface of the lid 6, the green ink 7 may be printed on the entire surface of the lid 6. If you do this, normally the lid 6 will be solid green, but when you add boiling water, the cross will begin to rise as shown in Fig. 4. Further, when the foam ink 3 is printed on the surface of the lid 6 other than the cross, and then the green ink 7 is printed on the entire surface, the periphery of the cross floats and is visible as described above. In this case, the heat insulation area becomes wider and the heat retention effect is high.

The lids of the first and second embodiments may be combined to obtain the effects of heat insulation and visibility at the same time. When a heat insulating material is used for the purpose of visual recognition, it may be a word such as "danger" or "heat", or a product name or a trademark, depending on the purpose of notification. Needless to say, the heat-foamable layer may be used for both visual recognition and heat insulation.

In the above-mentioned embodiment, the tableware made of paper such as a paper cup is used as an example, but of course, it may be applied to various tableware such as a cup made of plastic or glass.

[0016]

[Effect of device]

 Since the tableware of the first invention can be held by hand by putting hot water in it, tea and coffee can be enjoyed deliciously. And since the tableware of the second invention can be visually confirmed that it contains hot water, there is no need to worry about touching the container and getting burned.
