Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap, and more particularly, to a cap having a structure in which an inner portion not requiring decorativeness and a portion having an outer decorativeness are separable so that the cap can be used after use. Relates to a cap configured to discard only the inner part.

[0002]

[Prior art]

It is generally known that a cap has a top wall extending from the upper edge of the peripheral wall screwed to the outer periphery of the mouth and neck of the container body so as to close the upper opening of the mouth and neck. These can be coated with metal on the outside, provided with an uneven pattern on the outer surface, colored, printed, etc., or specially shaped, for the purpose of improving their appearance and increasing their commercial value. Or, these are combined.

[0003] However, the trend of resource conservation in recent years demands the reuse of articles, and it is not preferable to discard such a high unit price cap together with the container every time the contents of the container are used up. What can be reused is required.

[0004] The present invention has been made in view of the above points,
The present invention proposes a cap that has a rich decorative appearance when used, and that discards only the inexpensive inside after use and allows the outside to be used again.

[0005]

In order to solve the above problems, the cap of the present invention has a top wall 6 extending from the upper edge of the peripheral wall 5 and a locking projection 9 standing upright from the center of the upper surface of the top wall 6. A top wall 11 extends from an upper end edge of an inner wall member 2 and a peripheral wall 10 fitted non-rotatably and vertically movable around the inner wall member peripheral wall 5, and a window hole 13 formed in a central portion of the top wall 11. The outer wall member 3 is detachably fitted to the inner wall member 2 by inserting and protruding the engagement protrusion 9, and the lower surface opening having one end opened to the peripheral surface and the other end extended to the central portion. A plate-shaped locking member having a groove 14 and having a protruding portion of the engaging projection 9 protruding from the window hole 13 inserted into a peripheral opening 14a of the locking groove 14 and locked at the innermost center portion. And 4.

[0006]

After the locking member 4 is slid rearward from the state shown in FIG. 1, the outer wall member 3 can be lifted up and removed from the inner wall member 2. The removed outer wall material 3 and the locking member 4 can be mounted on the inner wall material 2 mounted on a new container body filled with the contents, and used again.

[0007]

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

FIGS. 1 to 5 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a cap. The cap 1 includes an inner wall member 2, an outer wall member 3, and a locking member 4.

The inner wall member 2 has a cylindrical shape with a lower end opening formed by extending the top wall 6 from the upper end edge of the peripheral wall 5, and the inner surface of the peripheral wall 5 is screwed to the outer periphery of the mouth and neck of the container body to be mounted. Thread 7
Has been established. In addition, a number of vertical protrusions 8 are provided around the outer periphery of the peripheral wall 5 at predetermined intervals in the circumferential direction. Furthermore, the top wall 6
At the upper end of the cylindrical base 9a, an engaging projection 9 is provided at the upper end of the cylindrical base 9a.

The outer wall member 3 has a cylindrical shape with a lower end opening formed by extending a top wall 11 from an upper end edge of a cylindrical peripheral wall 10 large enough to be fitted to the outer periphery of the inner wall member peripheral wall 5. A large number of vertical ridges 12 which can be respectively engaged with the vertical ridges 8 of the inner wall member 2 are provided around the inner surface of the inner wall 10 at predetermined intervals. In the center of the top wall 11, a circular window hole large enough to allow the engagement protrusion 9 to be inserted.
13 are drilled. Then, a peripheral wall 10 is formed around the outer peripheral wall 5 of the inner wall material.
The outer circumference is engaged with each other by engaging the vertical protrusions 8 and 12 with each other so that relative rotation is impossible and vertical movement is possible. The inner wall material 2 is fitted so as to be able to escape.

The locking member 4 is formed in a disk shape having substantially the same diameter as the upper surface of the outer wall material top wall 11 and having a thickness greater than the projection width of the engaging projection 9. A locking groove 14 having an opening at the lower end face extending to the center is formed. In the present embodiment, the locking groove 14 has a front T-shaped opening 14a on the peripheral surface, which is the shape of the protruding portion of the engaging projection 9 from the window hole 13, and the engaging projection 9 on the lower surface. The base 9a has a band-shaped opening 14b having a width that can be fitted therein, and is formed in a semicircular shape having substantially the same diameter as the locking plate 9b on the back surface of the center portion. In this embodiment, a hollow portion is provided inside for the reason of molding.

Then, the portion of the engaging projection 9 protruding from the window hole 13 is fitted through the peripheral surface opening 14a, and the locking member 4 is slid along the locking groove 14 so that the locking member at the innermost position of the groove 14 is locked. The engaging projection 9 is locked at the center of the member 4, and the upper surface of the outer wall material 3 is covered with the locking member 4. Vertical projections 15 are provided at predetermined positions on the left and right sides of the inside of the groove 14 so that the engagement projections 9 fitted into the central portion of the groove 14 are engaged so as to get over and engage naturally. ing.

In each of the above embodiments, the inner wall member 2, the outer wall member 3, and the locking member 4 are all made of synthetic resin.
Further, the outer wall material 3 and the locking member 4 are provided with decorativeness 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 wall material 2 is formed at the lowest possible cost and with emphasis on only the functionality. Further, in order to impart decorativeness and durability, the outer wall material and / or the outer surface of the locking member can be covered with a metal layer, if necessary.

[0014]

[Effects of the Invention] As described above, the cap of the present invention has the above-described structure, so that the outer wall material can be removed and only the inner wall material can be discarded as needed, and decoration can be performed in various forms. The outer wall material and the locking member having a good appearance or durability can be reused, and can sufficiently satisfy the recent demand for such a cap.

Also, the outer wall material can be removed by a very simple operation of removing the locking member by sliding it horizontally, and then pulling the outer wall material upward. The attachment and detachment of the outer wall material and the locking member to and from the material can be performed very easily.
