[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a glass bottle and a cap attached to the mouth of the glass bottle, FIGS. 2 and 3 are rear and side views of the glass bottle with the cap attached, and FIG. It is sectional drawing. The cap 1 is formed of a plastic material, is fitted and fixed to the bottle mouth 31 of the glass bottle 30, and has a substantially cylindrical cap body 10 having an inner cylinder 18 for pouring out the contents in the glass bottle 30. And a lid 20 which is openably and closably attached to the cap body 10 to open and close the opening 11 of the inner cylinder 18 of the cap body 10.

On the inner wall of the side surface 12 of the cap body 10, there is provided a retaining projection 17 that fits into a recess 32 formed directly below the mouth 31 of the glass bottle 30. On the side surface 12 of the portion 10, a circumferential cut groove 13 provided in a part of the circumferential direction at a position above the convex portion 17 and a circumferential cut groove 13 orthogonal to the circumferential cut groove 13. With the vertical groove 14 provided to the lower opening end 19, two flexible strips 12a and 12b are integrally formed. Also, each of the strips 12a and 12b is integrally formed with a projection 15a, 15b which is divided so that a locking projection 15 having an enlarged portion 16 is formed when the longitudinal grooves 14 are abutted. It is located in

A tongue 22 is formed integrally with the lid 20 so as to hang down from a side surface 21 of the lid 20. The tongue 22 protrudes from the longitudinal grooves 14 of the strips 12 a and 12 b. A hole 23 is formed in which the locking projection 15 having the protruding portion 16 formed in the form of the fitting is fitted. On the opposite side of the lid 20 from the tongue 22, a catching projection 24 for opening the lid 20 is provided.

With the above-described configuration, in a normal use state, the locking projection 15 formed by the projections 15 a and 15 b is fitted into the hole 23 of the tongue 22 of the lid 20. The cap main body 10 is hardly detached because the retaining projection 17 is fitted and fixed in the concave portion 32 of the glass bottle 30 in the retaining state. However, after the contents of the glass bottle 30 are used, when the fitting of the hole 23 of the tongue 22 of the lid 20 and the locking projection 15 of the strips 12a and 12b is released, the cap for the recess 32 of the glass bottle 30 is released. Since the retaining projection 17 of the retaining portion 17 of the main body 10 is loosened, an external force is applied in such a direction as to push the cap main body 10 against the glass bottle 30, so that the cap main body 10 can be easily removed from the vial 30. It can be removed from the mouth 31.
