As disclosed in Publication No. 85889, after fitting the fitting part formed on the peripheral edge of the plastic lid to the mouth edge of the plastic container, the fitting part is inserted into the cathode plate and the anode plate from the inside and outside. It is therefore known to dielectrically heat the mouth edge of the container and the fitting portion of the lid by sandwiching the container and passing high frequency waves through the cathode plate, thereby melting and sealing the two. This conventional method has no problem if the container and lid are circular, but if the container and lid are square as in the present invention, the corners of the square are uniformly shaped like the other parts. It is difficult to apply pressure and heat, and sealing defects may occur at the corners.

As disclosed in Japanese Patent No. 49-23713, a rotary drive shaft, an upper disk and a lower disk fixed to the drive shaft vertically and oppositely at a predetermined interval;
A bottle holder is placed on the outer periphery of the lower disk at predetermined intervals so that it can be raised and lowered freely, an insulating elastic body is provided on the lower surface of the upper disk to correspond to the bottle holder, and the bottle holder is moved. The high-frequency heating coil is placed parallel to the line and slightly above the upper disk, and as the upper and lower disks rotate, the bottle holder is lowered at the bottle loading/unloading section, and raised at the point where the high-frequency heating coil is located. A bottle cap sealing device is known in which the cap of the bottle opening is pressed against an insulating elastic body. This was previously proposed by the applicant and is suitable for mass production, but it has the following problems. The problem is that the high-frequency heating coil is located parallel to the line of movement of the bottle holder and slightly above the upper disk, so there is a considerable distance from the high-frequency coil to the cap to be heated. By heating the entire cap, a large amount of electricity is required.

広い範囲にわたつてシールされる。 Now, with the cap 2 fitted to the container body 1 as described above, when both are fed into a predetermined position directly below the device, the air cylinder 3 is operated and its rod 31 protrudes, and the elevating plate 4 At the same time, the pressing member 5 descends. Eventually, the elastic body 8 becomes the cap 2.
contacts the upper end of the fitting part 2a, but from this state,
When the rod 31 further protrudes, the elevating plate 4 compresses the spring 20 and descends, thereby pressing the elastic body 8 against the upper end of the fitting portion 2a. Then, the high frequency coil 6 is energized for the required time. As a result, the aluminum foil layer 1a on the rim of the container body 1 is heated by induction. Then, the fitting portion 2a is melted and heat-sealed to the rim of the container body 1. The sealing state at this time is shown in FIG. When the elastic body 8 is pressed by the fitting portion 2a, the elastic body 8 is elastically deformed so that its contact surface becomes a concave surface. As a result, the fitting portion 2a is sealed over a wide range not only over the upper end surface of the rim of the container body 1 but also over a part of the inner and outer surfaces following the upper end surface.

に加熱される。 By the way, if the magnetic body 7 is not arranged at the four corners of the high frequency coil 6, the high frequency coil 6
The strength of the magnetic field around the high-frequency coil 6 is not constant over the entire length of the path;
There is an imbalance in the strength of the magnetic field at the four corners of the container, and therefore the aluminum foil layer 1a at the rim of the container body 1 is less likely to be heated at the four corners than at other parts. , this problem is solved by the presence of the magnetic material 7. That is,
As is well known, the magnetic body 7 improves the electrical efficiency and magnetic flux density of the high frequency coil 6, so that the magnetic field around the four corners of the high frequency coil 6 is strengthened. Therefore, the aluminum foil layer 1a on the rim of the container body 1 is heated almost uniformly over its entire length.

By being able to make it as small as possible and by being able to locally heat only the upper end of the mouth rim of the container body,
Effective use of electricity can be achieved.
