Abstract

PROBLEM TO BE SOLVED: To obtain a process for jacketing solid fuels for heat insulation or heating which allows heat insulation or heating, mainly, of cooked food by maintaining the state of combustion over a long period of about >=60 min from ignition before reaching complete combustion. SOLUTION: A floor plate 22 at the middle position has a through hole 22a. Above the through hole, a metallic foil 32b, which is larger than the diameter of the through hole and has a small pore, is positioned. A solid fuel 30, sliced in a size substantially equal to the diameter of the through hole, is positioned above the metallic foil. By pressing down a rod 24 onto the center of the solid fuel, the bottom and circumferential surfaces of the solid fuel 30 is jacketed with a vessel-formed metallic foil 34. The jacketed fuel is received by a receive plate 28.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solid fuel mainly composed of alcohol, which is packaged mainly with a flame-retardant material such as an aluminum foil,
The present invention relates to a method for covering a solid fuel for heating.

[0002]

2. Description of the Related Art A solid fuel obtained by cutting a solid fuel rod-shaped molded product containing alcohol as a main component, exposing only the upper portion and wrapping it with an aluminum foil as an exterior is known, for example, from Japanese Utility Model Publication No. 58-29164. I have.

[0003] Further, there is also known a solid fuel in which a similar liquid fuel is poured into a metal can, solidified by cooling, and then provided with a lid which can be partially opened like a window. In this case, a metal can is used. Therefore, the cost is high, and after use, it is disposed of as a bulky empty can, but this processing is troublesome.

[0004] The above-mentioned inexpensively obtained solid fuel with an aluminum foil exterior is generally sealed and packaged with a resin film to prevent evaporation, and further provided with a heat adhesive layer on the inner surface, which is bonded to the resin film. It is wrapped and wrapped in aluminum foil with the entire upper surface open from the bottom so that the resin film is completely burned together with the solid fuel from the top in use. An apparatus which facilitates refuse treatment by receiving it in a container and discarding it as it is is known, for example, from Japanese Utility Model Application Laid-Open No. 52949/1985.

[0005] For example, in the case of a rice cooker, and in a drive-in, lunch at a golf course, etc., it is preferable for the customer to finish the cooking in a short time, and for the business owner to increase the number of customers, so-called fast customer turnover. In response to this, the applicant of the present application has proposed a solid fuel for early cooking that is provided with a large exposed area of the combustion part and is provided as an exterior.
No. 246616.

[0006] However, a faster customer turnover rate is required. Efficiency is to prepare a large number of dishes, such as group customers, in the kitchen before cooking and bring them to the dining table used by many people so that customers can eat them as soon as they are seated. It is a target.

[0007] In this case, the cooking place prepares and prepares meals in accordance with the reservation time when the group customers arrive, but the reservation time is not protected by traffic conditions and the like, and meals are delayed after this time. In many cases, the dishes cool down during that time.

In view of such circumstances, the applicant of the present invention has proposed a solid fuel for keeping warm and warming, which is mainly used for keeping warm or warming cooked dishes.
No. 59093. Examples of the embodiments include:
As shown in FIG. 4, an exterior aluminum foil 10
A cutout or exposed portion 12a, 12b, 12c is provided as a igniting portion on the surface portion of a, 10b, 10c which comes into contact with air.
