Description

[Detailed description of the invention] Industrial application field The present invention relates to a new metal foil case for storing foods such as fried foods, which has liquid absorption properties and prevents liquid that has leaked from the stored food from accumulating. The present invention aims to provide a novel metal foil case that can also be used as a metal foil case.

Prior Art In Makunouchi bento boxes, etc., a large number of various side dishes such as fried foods, simmered foods, grilled fish, processed foods, etc. are usually arranged in a limited space. If excess oil or broth adhering to the food is transferred to the food that comes into contact with it, the taste of the food will be spoiled even if the food is delicious.

Therefore, conventionally, fried foods, boiled foods, etc. are housed in cup-shaped aluminum foil cases, which prevents excess oil or broth from transferring to or from other foods. I was preventing it from happening.

Problems that the invention aims to solve: However, the conventional aluminum foil cases mentioned above have no liquid absorption properties, so for example, fried chicken or tempura can be stored in an aluminum foil case to be used as a bento box. When these fried foods are placed in a sealed container, excess oil adhering to these fried foods or moisture evaporated from other foods condenses and accumulates at the bottom of the case.
As a result, there was a problem in that the fried food inside the case became sticky and the taste of the food deteriorated, and furthermore, when oil and water inside the case leaked out, there was also a problem that the taste of other foods was spoiled.

The present invention was developed to solve the above-mentioned conventional problems, and includes a metal foil case that is not only liquid-absorbing but also capable of preventing liquid that has leaked from stored food from accumulating. The purpose is to provide.

Summary of the invention In order to solve the above-mentioned problem, this invention laminates a liquid-absorbing sheet over the entire inner surface of a metal foil case body, and forms a parallel striped pattern over the entire surface of the liquid-absorbing sheet and the metal foil case body. It is a bonded metal foil case,
The liquid flowing out from the stored food is sucked and retained by the liquid-absorbing sheet and the fine gaps that are open to the atmosphere and have a capillary function, which are formed in the non-adhesive part between the liquid-absorbing sheet and the metal foil case body, and the liquid is absorbed into the case. This prevents the accumulation of water.

Embodiment Hereinafter, an example of the metal foil case of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is an overall perspective view of a metal foil case 1 according to the present invention, which includes a cup-shaped metal foil case 2 made of aluminum foil, etc., and a moisture-absorbing material such as Japanese paper laminated and bonded to the entire inside of the metal foil case 2. The absorbent sheet 3 is made of a sheet material with good properties.

FIG. 2 is a perspective view showing the cup-shaped metal foil case 1 developed into a flat plate and partially peeled off, showing the metal foil case body 2 and the liquid-absorbing sheet 3 laminated thereon. are adhered to each other by adhesive portions 4 in a parallel striped pattern, and in non-adhered portions other than the adhesive portions 4, minute gaps 5 open to the atmosphere are formed as shown in FIG. This gap 5
It is designed to have a capillary function to suck and hold the liquid flowing out from the stored food.

The flat material shown in Fig. 2 above is pressed with a die (not shown) to form a bottomed inverted truncated cone having corrugations 1a, 1a, . . . on the circumferential side as shown in Fig. 1. It is molded into

In the metal foil case 1 configured as described above, liquids such as oil exuded from stored foods such as fried foods adhere to and are absorbed by the liquid-absorbing sheet 3, and permeate inward of the liquid-absorbing sheet 3. . This permeated liquid is further drawn into the gap 5 open to the atmosphere by its capillary action. Therefore, the liquid spilled from the food does not accumulate in the bottom of the metal foil case 1, and therefore, the stored food does not become sticky or lose its taste, unlike in the conventional case.
There is no impact on other foods due to the outflow of the retained liquid.

Effects of the Invention As explained above, according to the present invention, a liquid-absorbing sheet is laminated on the entire inner surface of a cup-shaped metal foil case body, and the liquid-absorbing sheet and the metal foil case body are covered in parallel stripes over the entire surface. It is bonded in a pattern and has a capillary function by forming fine gaps that are open to the atmosphere in the non-adhered parts, so the liquid flowing out from the stored food is absorbed between the liquid absorption sheet and the fine gaps that have a capillary function. This prevents liquid spilled from food from accumulating inside the case.
