DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a cap. The cap 1 includes an inner cap 2, an outer cap 3, and a fixing ring 4 as main members.

The inner cap 2 is made of a synthetic resin or the like, and has a cylindrical shape with a lower end opening formed by extending a top wall 6 from an upper end edge of the peripheral wall 5.
A thread 9 is screwed around the outer periphery of the mouth and neck portion 8 of the vehicle. Also, a number of vertical protrusions 10 are provided around the outer periphery of the peripheral wall 5 at predetermined intervals in the circumferential direction.

The outer cap 3 is formed of a synthetic resin or the like, and a top wall which abuts and covers the upper surface of the inner cap top wall 6.
A peripheral wall 12 is vertically suspended from a peripheral edge of the eleventh, and a large number of elastic engagement pieces 13 are vertically suspended at a predetermined circumferential interval from a lower end edge of the peripheral wall 12. Each of the engagement pieces 13 is inclined so that the lower end is spread outward, and has a rectangular plate shape having a thin upper part, and a lower part of the inner surface is formed with a projection for engaging the lower end edge of the inner cap peripheral wall 5.
13a are protruding respectively. When the peripheral wall 12 is fitted to the inner cap 2, the lower edge thereof is located above the lower edge of the inner cap peripheral wall 5, and when each engaging piece 13 is elastically deformed inward, the projection is formed. 13a is configured to engage with the lower edge of the inner cap peripheral wall 5 without slack. Further, a number of vertical ridges 14 are provided around the inner surface of the peripheral wall 12 at predetermined intervals in the circumferential direction, and each ridge 14 is configured to be able to engage with each of the ridges 10 of the inner cap 2. When the outer cap 3 is fitted into the outer cap 2, it can move up and down freely, but cannot rotate relative to each other.

The fixing ring 4 has a cylindrical shape with upper and lower end openings formed of a synthetic resin or the like, and an inward flange-like projection 15 protruding inward from the upper end edge. 16 is rotatably fitted to the outer cap 3 so as to be rotatable relative thereto. In addition, a number of protrusions 17 each having a rectangular shape in front are projected from the lower portion of the inner surface at a predetermined interval in the circumferential direction, and a lower portion of the elastic engagement piece 13 opened outward between the respective protrusions 17 is provided. It is configured to be insertable. Further, when the fixing ring 4 is rotated and the above-mentioned elastic engaging pieces 13 are abutted and locked inside the respective projecting portions 17 while being elastically deformed, the respective engaging pieces are
The thirteen projections 13a engage with the lower edge of the inner cap peripheral wall 5 so that the inner cap 2 and the outer cap 3 are firmly fixed.

A rectangular projection 18 for restricting the rotation width is provided at a predetermined position directly below the projection 15 of the fixing ring 4, while a rectangular projection 18 having a predetermined width is provided at a predetermined position at the lower end of the outer cap peripheral wall 12. By forming a concave groove 19 for regulating the dynamic width, the protrusion 18 is configured to be rotatable between both ends in the concave groove 19,
The relative rotation width between the outer cap 3 and the fixing ring 4 is regulated. At one end, each engagement piece 13 is elastically deformed inward by each protrusion 17, and at the other end, each engagement piece 13 is It is configured to be located between the parts 17.

The outer cap 3 and the fixing ring 4 are used by giving a decorative property and durability by selecting a resin to be used, coloring, printing, transferring, imparting a concavo-convex pattern or a combination thereof. On the other hand, the inner cap 2 is formed at a cost as low as possible and focusing only on the functionality.

[0015]

[Effect of the Invention] As described above, the cap of the present invention has the above-described structure, so that when the contents of the container body to be mounted are used up, the inner cap can be removed and only the inner cap can be discarded. The outer cap and the fixing ring, which have been improved in appearance by being decorated in various forms, can be reused, and can sufficiently satisfy the recent demands of such caps.

Also, when removing the inner cap, the fixing ring can be relatively easily rotated with respect to the outer cap and then pulled up, and when the inner cap is newly mounted, the inner cap is attached to the outer cap. Can be performed by an extremely simple operation of relatively rotating the fixing ring to a predetermined position after fitting.

Further, each projection elastically deforms each elastic engagement piece inward from a state where each projection is located between the elastic engagement pieces, and engages the lower end of the inner surface with the lower edge of the inner cap peripheral wall. Since the fixing ring is provided so as to be capable of horizontal rotation of a predetermined width up to the state, when removing the inner cap or mounting and fixing the inner cap, there is no inconvenience such as excessive rotation of the fixing ring excessively, Engagement and disengagement of each elastic engagement piece can be reliably performed.
