The conventional plastic case of this type has a configuration in which a concave groove is formed on the entire circumference of the mating surface of the main body or the lid, and an annular packing is inserted into the concave groove. , Providing a protrusion on the opening edge of the groove will cause an undercut during blow molding, so a retaining lock can be formed on the opening of the groove. It takes considerable skill to insert it evenly in the groove over the entire circumference of the surface, and if the packing has a length that is slightly longer or shorter than the total length of the groove, especially at corners, Wavy unevenness was generated on the sealing surface, which was a cause of impairing the sealing performance inside the case.

On the mating surface 6 of the lid body 2, a concave groove 9 having a wider width toward the opening side is formed over the entire circumference, and in the concave groove 9, a packing made of an elastic foam having a closed cell structure is formed.
10 is stuck all around. The sealing surface of the packing 10 is a flat surface. On the other hand, the mating surface 5 of the main body 1 is formed with a ridge 11 corresponding to the sealing surface of the packing 10 of the lid 2. The width of the protrusion 11 is much narrower than the opening width of the concave groove 9 and has a solid shape. The ridge 11 is pressed against the packing 10 in a state where the lid 2 is closed on the main body 1 and is engaged with the packing 10 to expand it so as to fill the inside of the groove 9.

The plastic case configured as above
By removing 3, 3 from the latch receivers 4, 4 and lifting the lid body 2 upward, the lid body 2 can be detached from the main body 1 and the case can be opened. Also, the case can be closed by covering the opening of the main body 1 with the opened lid 2 and hooking the latches 3 and 3 on the latch receivers 4 and 4. However, when the case is closed, the lid 2 The ridge 11 on the main body 1 side is pressed against the packing 10, and the ridge 11 is engaged with the packing 10. The packing 10 is deformed and expanded to fill the concave groove 9. For this reason, the space between the mating surfaces 5 and 6 of the main body 1 and the lid body 2 is completely sealed by the packing 10 and the ridge 11, and the inside of the case is kept in a hermetically sealed state.
