Description

[Detailed Description of the Invention] Industrial Application Fields The present invention is particularly useful for easily storing food and drinks in airtight containers made of paper or plastic (hereinafter simply referred to as "Panku"), which are often found in drinks such as milk. This invention relates to a new container for food and beverages that has been developed to be able to be heated at high temperatures.

rPrior Art 1 In recent years, a wide variety of food and drink products containing bukkake, which is often found in milk and the like, have been commercially available. This pack is mainly a paper container, and it is not only available in household size, but it is also convenient to carry around at stores, while traveling, driving, hiking, etc., and is a one-lot type that can be taken immediately on the spot. It is very popular as it is affordable.

This means that the amount of contents is reasonable, there is no leftover drink, and
This is largely due to the fact that the containers are made of paper, making them cheap and economical, and that they can be easily disposed of once empty.

If you look at the structure of this pack, you will find that drinking [1 is J) -
Some of them were designed so that they could be opened easily, but in any case, most of them were simply made into airtight containers.

4. Problems with the Prior Art In other words, there has never been a pack that has its own means for easily warming the contents as focused on in the present invention.

For this reason, as mentioned in -1-, there are packaged drinks*; All the drinks available were bottled or canned, and I couldn't find many packaged drinks. Also, even if there is a pack, it must be warmed by soaking it in hot water at an appropriate temperature, and doing this will leave the outside of the pack wet, which can be unsanitary, especially since it is made of paper. , was concerned about the problem of diminishing product value. Furthermore, it is not possible to popularize hot beverages due to negative factors such as the need for considerable equipment and heating stars to maintain the temperature of the hot water to heat many beverages. Therefore, there is.

It may be difficult to heat J5 in a household microwave oven, but it is not suitable because it is made of a material with low mJ heat resistance, such as a pack or paper.

In other words, there was no Ik technique that could heat the skin easily and at low cost using a simple device.

Step r for solving problem r Therefore, in order to solve problem -1-, the food and drink container of the present invention was developed. Its features include a current-carrying heat-generating layer (2) that can conduct electricity from one end of C to the other end of the closed container (1), and a power-receiving contact portion (3) provided at both ends of the current-carrying heat-generating layer (2). It's about becoming.

The current-carrying heat-generating layer (2) provided in the present invention includes a metal foil layer such as an aluminum foil, a current-carrying heat-generating wire layer, a current-carrying heat-generating resin layer, a current-carrying heat-generating acid layer, a vapor deposition layer, a plating layer, etc.

Refers to something that has the property of generating heat by increasing the current density.

1- Preferably, the metal foil is aluminum or stainless steel, and the current heating wire is preferably a steel wire, a conductive fiber filament, or the like. In addition, the current-carrying heat-generating resin layer may be made of a synthetic resin with carbon particles or metal powder added to it, and the current-carrying heat-generating m-acid layer may be made of a woven fabric or non-woven fabric with carbon particles or metal powder added. .

The vapor deposited layer is made by vapor depositing aluminum or other metal onto the container, and the plating layer is made by plating aluminum or other metal onto the container.

The current-carrying heating layer (2) preferably has a thickness of several microns to several tens of microns, and is preferably provided in a place other than the inner surface of the container where electricity cannot flow through the contents. Particularly from the standpoint of insulation, it is best to provide it between the outer surface and the inner surface.

Further, it is preferable to provide a layer of heat insulating material on the outside of the current-carrying heat generating layer (2) so that the generated heat can be efficiently used to heat the contents.

r effect 1 In such a food and drink container, the power receiving contact part (:l)
When electricity is applied from (:l) to the energized heat generating layer (2), this energized heat generating layer (2) generates heat, which has the effect of warming the contents in the container.

r Example 1 The food and drink container of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of the food/beverage container of the present invention, and FIG. 2 is a central sectional view of FIG. 1.

3 to 6 are perspective views showing other examples.

In the example shown in FIGS. 1 and 2, a rectangular sealed container (1) is provided with an electrified heat generating layer (2) extending from the vicinity of the edge to the bottom of the wide side surface of the sealed container (1). are provided, and both ends of this energizing heat generating layer (2) are used as power receiving contact portions (3) (3).

The airtight container (1) has an insulating waterproof layer (6) that has a plastic coating insulation and water leakage prevention function on the innermost side, and a heat insulating layer (7) is formed on the outside of the current-carrying heat generating layer (2). There is.

The power receiving contact parts (3) and (3) are both located at the middle part of the wide side surface.
6= Positioned so as to face ! The surface is exposed in part A.

Since the receiving contact parts (:1) (3) are exposed to the outside of the sealed container (1), the candy 1rL terminal (4) is connected to these.
(4) makes it possible to easily communicate with the current-carrying heat generating layer (2) by making contact between them. However, the purpose of exposing the receiving contact portions (:1) and (3) in this way is to improve the contact between the candy 11 and the terminal.

Depending on the structure of the power feeding end f, it is also possible to make the power receiving contact portions (3) (3) into a socket structure into which a lead wire or the like can be inserted, and is included in the present invention.

Further, as shown in 2nd F; 4, in this example, the energizing heat generating layer (2) is provided as an intermediate layer between the outer surface and the inner surface of the container, thereby providing an insulating structure for both the inside and outside of the closed container (1).

The example shown in Fig. 3 is the opening 11 at the top of the house-shaped airtight container (1).
The power receiving contact portions (:1) and (3) are provided on the edge with their positions shifted in the rl direction.
