[Effects of the Invention] As described above, according to the present invention: Since the sealed container is constructed by the attraction force of the magnet, the V!
The adhesive area can be flattened, so it can be adhered in a short time, and it is very easy to clean, making it effective not only for applications where hygiene is important, such as food products, but also for medical applications where contamination with impurities is a concern. It is also effective for The productivity of closed containers can be improved by casting a magnet alone or enclosing a magnet and a magnetic circuit with a yoke on the back of the magnet. By forming unevenness such as knurling on the back and side surfaces of the yoke, it is possible to prevent the magnet from falling off from the molded product. Furthermore, cast molding not only allows for the easy application of wood grain patterns and engravings on the outer periphery of sealed containers, but also makes it suitable for producing a wide variety of small plates because the molds are easy to manufacture. .
