DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple electromagnetic cooker container made of a material such as paper or plastic that can be incinerated and disposed of.

[0002]

2. Description of the Related Art This type of container is disclosed in Japanese Patent Application Laid-Open No. 62-1336.
No. 91 and JP-A-63-55884. First, Japanese Patent Application Laid-Open No. 62-133691 discloses that at least the inner surface of the side wall of a cup made of an inexpensive incinerated and disposable material such as paper or plastic is provided with a thin electromagnetically heatable thin plate such as an aluminum foil or a thin copper plate. It is described that a layer was provided. As a result, a hot drink of only one cup can be easily obtained in a short time and economically when desired. Also, JP-A-63-55884 discloses that an electromagnetic cooker container is formed of cardboard,
It is described that a magnetic material piece that can be electromagnetically induced is embedded in the bottom wall. Thereby, an inexpensive and easy-to-manufacture container for an electromagnetic cooker can be provided. FIG. 5 is a cross-sectional view of a conventional cup container for cup noodles representing an instant food. 1 is a container for cup noodles, 2 is an inverted truncated conical side wall whose diameter increases toward the top, 3 is a bottom wall that fits and closes the bottom 2a of the side wall 2 to close the bottom, and 4 is a cup A lid 6 for closing the upper opening 5 of the noodle container 1 is a dry cup noodle accommodated in the cup noodle container 1. The side wall 2, bottom wall 3, lid 4
Is made of paper or similar material so that it can be incinerated and disposed of. The lid 4 curls the upper end 2b of the side wall 2 and glues the curled portion. However, this gluing is only for temporary fixing, and when the user tries to eat cup noodles,
It is sufficient that the adhesive has enough adhesive strength to be easily peeled off. The bottom 2a of the side wall 2 is fitted with the bottom wall 3 as described above.
In this fitting method, as shown in FIG. 6, the side wall 2 is extended to the lower end portion, and then folded inward to form a folded portion 7. Further, the peripheral end of the bottom wall 3 is bent downward to form a flange 3a. Then, the flange 3a of the bottom wall 3 is inserted between the side wall 2 and the folded portion 7, and the bottom 2a is fitted with a gouge or adhesive. How to eat such cup noodles is already well known, but to explain,
Is slightly peeled off, hot water is poured into the container 1 from the gap, closed again with the lid 4, and steamed for about 3 minutes. Then cover 4
Is removed from the container 1 and the noodles are mixed well before eating.

[0003]

However, in order to allow such a cup noodle container 1 to be induction-heated by an electromagnetic cooker, as described in the prior art described above, the side wall 2 or the bottom wall 3 is required. A magnetic metal that can be induction-heated may be arranged at the bottom. However, for example, when a magnetic metal is disposed on the bottom wall 3, when the bottom wall 3 is bent to form the flange 3a,
The ends of the magnetic metal bend together and come closer to the electromagnetic cooker than other parts. This is because the magnetic metal is bent and fitted together with the bottom wall to prevent a large force from being applied to the fitting part due to the movement of the magnetic metal and the fitting is disengaged. In order to manufacture with reduced accuracy, the magnetic metal is actually designed not to be bent, but it is considered that the cause is that the position is shifted and bent. In any case, when the end of the magnetic metal approaches the electromagnetic cooker side, the magnetic flux of the electromagnetic cooker concentrates at the end, and there is a possibility that the temperature becomes abnormally high. If the temperature becomes abnormally high, the metal may expand in the fitting portion, or if the fitting is performed by bonding, the adhesive may be dissolved and the fitting portion may be disengaged. Also, when a magnetic metal is disposed on the side wall 2, since the lower end portion is close to the electromagnetic cooker, the magnetic flux may be concentrated and abnormal heating may occur. Since the lower end of the magnetic metal provided on the side wall is located in the vicinity of the fitting portion where the structural side wall and the bottom wall are fitted, there is a possibility that the temperature of the fitting portion rises and the fitting is disengaged as described above. .

[0004] The present invention is to solve such a problem.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below, but those given the same reference numerals as those in the prior art have the same functions and will not be described. In FIG. 1, reference numeral 8 denotes a first folded portion obtained by folding the lower end of the side wall 2 upward;
Is a second folded portion obtained by further folding the end of the first folded portion 8 downward, 10 is a bottom wall formed of a magnetic metal plate such as aluminum or a thin copper plate capable of induction heating, 1
Reference numeral 1 denotes a flange which is a fitting portion formed by bending a peripheral end of the bottom wall 10 upward. Numeral 12 indicates the fitting portion at the lower end of the side wall 2 as a general term. The first folded portion 8
Acts as a spacer part for separating the bottom wall 10 from the mounting surface and leaving a gap, and providing an air layer between the bottom wall 10 and the mounting surface,
The heat in the container 1 is insulated. The bottom wall 10
As shown in FIG. 2, the flange 11 is inserted between the first folded portion 8 and the second folded portion 9 and then fitted by crimping or bonding such as goby caulking. 3, reference numeral 13 denotes an electromagnetic cooker main body, 14 denotes a ceramic mounting table on which a pot or the like for induction heating is mounted, 15 denotes an operation unit on which a start key and a display unit are arranged, and 16 denotes a mounting table 1.
