The lower end edge portion 11 is formed to be thin, and a thread 13 is provided around the inner surface of the thin portion 11a. In addition, a large number of vertical protrusions 14 which can be fitted into the respective vertical grooves 10 of the inner wall material 2 are provided around the inner surface of the peripheral wall 11 above the threads 13 at predetermined intervals. Further, a short cylindrical portion 15 is provided vertically from the center of the rear surface of the top wall 12.

The locking member 4 has a ring-shaped base 4a having a semi-elliptical cross section, and a screw 16 which is screwed with the screw 13 is provided on an outer surface of the base 4a above the inner edge of the upper surface of the base 4a. At the same time, a threaded tube portion 4b having the same thickness as the recessed portion of the thin portion 11a is provided upright, and a flange 17 for locking the lower surface of the inner wall material peripheral wall 5 inward from the lower edge of the inner surface is provided. It is constructed by protruding.

The inner wall surface of the outer wall member 3 constructed as described above is fitted into each of the recessed grooves 10 with the vertical ridges 14 on the outer wall of the inner wall member peripheral wall 5, so that relative rotation is impossible and vertical movement is possible. Then, the screw portion 4b of the locking member 4 is screwed into the thread 13 of the outer wall material 3, and the flange 17 is abutted and locked to the lower surface of the inner wall material peripheral wall 5 to thereby lock the inner wall material 2 The outer wall 3 is attached and fixed to the cap 1 to form the cap 1. At this time, the lower surface of the short cylinder 15 of the outer wall material 3 is abutted and locked on the upper surface of the inner wall material top wall 6.

FIGS. 3 and 4 show another embodiment of the present invention. In this embodiment, an enlarged diameter portion 5a is formed by enlarging the lower edge of the peripheral wall 5 through an outward flange 18. A pair of threaded pieces 19 project from the outer periphery of the enlarged diameter portion 5a, and the upper portion of the outer periphery of the peripheral wall 5 is formed thin so that a number of vertical projections 20 are formed around the outer surface of the thinned portion 5b at predetermined circumferential intervals. To form the inner wall material 2.

The outer wall member 3 has a cylindrical wall 11 having a size that can be fitted to the outer periphery of the inner wall member 5 and a top wall 12 from an upper edge of the cylindrical wall 11.
A cylindrical projection having a lower end opening formed by extending the outer peripheral wall 11 is provided with a fitting ridge 21 from the outer peripheral lower end edge thereof. The ridges 22 are provided circumferentially at predetermined intervals in the circumferential direction.
