Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for covering a printing body of an extrusion type stamp, an extrusion type lipstick and the like.

[0002]

2. Description of the Related Art Conventionally, caps of this kind have a cylindrical body with one end closed and can be manually inserted / removed for each operation, or can be automatically opened / closed in response to an operation for moving a printing medium in and out. .

[0003]

Disadvantages of the prior art: However, the fitting / removing cap is not only troublesome to operate, but it may be lost, and it may stain hands and clothes. It is complicated and expensive, and has drawbacks such as poor durability.

[0004]

SUMMARY OF THE INVENTION The present invention has been developed to solve these drawbacks, and it has a simple structure and can be manufactured at low cost and has durability, and moreover, it is a writing instrument with a seal or an automatic opening / closing seal. An object of the present invention is to provide a device, a lipstick, and the like that can be widely used as a cap.

[0005]

The present invention will be described in detail with reference to the embodiment shown in the drawings. The upper end of the inner cylindrical body 2 is composed of a cylindrical outer cylindrical body 1 and an inner cylindrical body 2 inscribed in the outer cylindrical body 1. Has a curved surface 3 along the inner peripheral surface of the outer cylindrical body 1 and has free end edges 4, 4
, The central portion 6 of the base end edge 5 is connected to the upper end edge of the inner cylinder body 2 by the connecting portion 7, and the other portion 8 of the base end edge 5 is contactable to the upper end edge 9 of the inner cylinder body 2. A pair of lid pieces 10 and 10 are provided so that the lid pieces 10 and 10 can be biased in opposite directions.
0 and 10 are pressing bodies 11 incorporating a lipstick, a printing body 12 and the like.
It is opened by being pressed by.

The inner cylindrical body 2 is arranged at a position inside the outer cylindrical body 1 by approximately the length of the lid piece 10, and the lid pieces 10 and 1
The free edges 4 and 4 are not exposed to the outside of the outer cylindrical body 1 when 0 is opened.

In order to manufacture the lid pieces 10 and 10, first, a steel plate material is clamped into the shape of the inner cylindrical body 2 and the lid pieces 10 and 10 in the closed state, followed by quenching. 10
The free end edges 4 and 4 are formed by slitting with a cutter from the abutting apex position along the axis to form the free end edges 4 and 4 in the opposite direction in the direction perpendicular to the axis. After the slitting process, the central portion 6 is left and the connecting portion 7 is connected.

After the slitting process, the lid pieces 10 and 10 are urged in the opposite direction by the spring effect of the connecting portion 7 so that both the free end edges 4 and 4 abut and the upper end edge of the inner cylindrical body 2 is abutted. Base edge 5
Will get in touch.

The pressing body 11 incorporates the printing body 12 and is elastically supported by a spring 13, and the rear end of the pressing body 11 is
A pressing member 14 slidably fitted to the lower opening end of the outer cylindrical body 1 is connected so as to be pressed, and the outer peripheral edge of the pressing body 11 is pressed against the bias of the lid pieces 10 and 10. By doing so, the lid pieces 10 and 10 can be freely opened.

In the figure, reference numeral 15 is a hook that engages with a retaining hole 16 provided in the outer cylindrical body 1, and when the engagement is released, the spring 13 works to restore the pressing body 11 and the pressing member 14. The lid pieces 10 and 10 are closed.

The pressing body 11 has a stick-shaped lipstick instead of a printing body.
An eraser or the like may be incorporated.

FIG. 3 shows a rear shaft portion 18 of the telescopic ball pen 17.
Is used as a pressing body 11, and the printing body 12 is fitted into the pressing body 11 of the rear shaft portion 18 and is connected between the rear shaft portion 18 and the outer cylinder body 1 via a spring 13 so as to be freely pressed. .

[0013]

The present invention is embodied as described above, and the printing body 1
When 2 is used, the outer cylinder 1 is placed at a position where it is pressed, and the pressing member 14 is pressed against the bias of the spring 13 and the lid pieces 10 and 10, so that the lid pieces 10 and 10 are The printed body 12 of the pressing body is exposed and imprinted in contact with the inner peripheral surface of 1.

After pressing, the pressing member 14 is released to restore the pressing body 11 by the spring 13, and at the same time, the lid pieces 10 and 10 are closed.

The hook 15 is used when the pressing operation is continuously repeated.
And the hooking hole 16 are engaged with each other to leave the printed body 12 exposed.

In the case of the telescopic ball pen 17, the rear shaft portion 18
The printed body 12 of the pressing body 11 may be pressed by pressing, and the pressing body 11 is restored by releasing the pressing as before, and the lid pieces 10, 10
Closes.

When a stick-shaped lipstick or the like is incorporated in the printing body 12, the application work may be performed with the lipstick or the like being exposed, and the pressing of the pressing body may be released after the work is completed.

[0018]

As described above, the present invention comprises a cylindrical outer cylinder body 1 and an inner cylinder body 2 inscribed in the outer cylinder body 1. It has a curved surface which follows the peripheral surface, the free end edges 4 and 4 of which are in contact with each other, the central portion 6 of the base end edge 5 is connected to the upper end edge 9 of the inner cylinder body 2, and the other portion is the inner cylinder. A pair of lid pieces 10 and 10 that can be brought into contact with the upper edge of the body 2 is provided so that the lid pieces can be biased in opposite directions, and the lid pieces are pressed by a pressing body 11 incorporating a printing body or the like. Since it can be freely opened from the inner side, it is possible to perform embossing and the like by simply pressing a pressing body incorporating a printing body and the like, and it has a simple structure and durability, and can be provided at low cost.

The lid pieces 10 and 10 are formed by pressing a steel plate material into the shape of the inner cylindrical body 2 and the closed lid pieces 10 and 10 and then press-hardening the pieces to bring them into contact with each other. The free ends 4 and 4 are formed by slitting with a cutter from the apex position along the axis, while the free ends 4 and 4 in the opposite direction are slit from the end positions of the free ends 4 and 4 in the direction perpendicular to the axis. However, thin and precise processing can be performed by connecting the connecting portion 7 with the central portion 6 left, and by adjusting the remaining width of the connecting portion 7 in the opposite direction without using a spring or the like. It is convenient because you can adjust the strength of the activation.
