Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal stamp, in particular a penetrating seal, in which a cap covers and protects a stamp face of a stamp when not in use, and when the stamp is used, the cap can be opened and stamped as it is.

[0002]

Penetration marks require a cap to prevent evaporation of the ink contained therein. A conventional general penetrating seal cap is almost separated from the seal stamp main body as disclosed in Japanese Patent Laid-Open No. 5-185709. Such a cap has to be removed from the stamp main body each time it is stamped, which is troublesome and may be lost when it is removed.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a novel seal stamp which can easily open the cap at the time of imprinting and can prevent loss of the cap at the time of opening.

[0004]

In order to achieve the above object, the stamp of the present invention has a seal face 2 of a penetration mark 1 from an opening at one end.
A cap 4 that covers the opening and is in a closed state is rotatably attached to the outer cylinder 3 that exposes the outer cylinder 3, and the cap 4 is urged by a spring 5 so as to always rotate in the opening direction. Attach the ring 6 to the outer periphery of 3 so that it can rotate.
The cap 4 is provided with a projecting piece 7 that enters the inside of the ring 6 in the closed state, and a recess 8 is provided on the outer surface of the projecting piece 7. The configuration is characterized in that the convex portion 9 that can be inserted or removed by the rotation of is provided on the inner surface portion of the ring 6.

[0005]

In the closed state of the cap 4, the convex portion 9 of the ring 6 is fitted and locked in the concave portion 8 of the protruding piece 7 provided on the cap 4. When the ring 6 is rotated from this state to cause the convex portion 9 to escape from the concave portion 8 of the protruding piece 7, the locked state is canceled,
The cap 4 is rotated in the opening direction by the force of the spring 5, and the marking surface 2 of the permeation mark 1 is exposed from the opening at one end of the outer cylinder 3 and can be stamped. After the marking is completed, the cap 4 is rotated in the opposite direction against the spring 5 to cover the opening of the outer cylinder 3, and the ring 6 is rotated so that the convex portion 9 thereof becomes the concave portion 8 of the projecting piece 7 of the cap 4. Insert and lock. As a result, the closed state of the cap 4 is maintained.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show the closed state of the cap 4, and FIG.
6 shows the cap 4 in the open state. First, as shown in FIG. 5, the outer cylinder 3 is opened at one end to accommodate the permeation mark 1 therein, and the printing surface 2 of the permeation mark 1 is exposed from the opening. The permeation mark 1 is made of an elastic porous material and comes into contact with an ink storage body (not shown) such as a sponge arranged in the back, and ink is supplied from the ink storage body by a capillary action. It is designed to exude ink, and it is not necessary to attach cinnabar flesh every time it is imprinted. A guide cylinder 10 slidable in the longitudinal direction of the outer cylinder 3 is arranged on the outer peripheral portion of the permeation mark 1, and the guide cylinder 10 is provided.
Is urged by a spring (not shown), and its tip is normally projected slightly forward of the stamp surface 2.
The guide cylinder 10 comes into contact with the paper surface before the stamp surface 2 at the time of marking, and when the outer cylinder 3 is pushed toward the paper surface, the outer cylinder 3
The stamp surface 2 is brought into contact with the paper surface by immersing the stamp surface 2 inside. Therefore, when the leading end of the guide cylinder 10 comes into contact with the paper surface, the stamp surface 2 is also parallel to the paper surface, and printing is performed in that posture, so that a good imprint can be obtained.

A rear end portion of the cap 4 is rotatably attached by a shaft 11 to a rear surface portion of the peripheral wall near the opening of the outer cylinder 3. When the cap 4 is rotated forward with respect to the outer cylinder 3, as shown in FIG. 2, the cap 4 covers the opening of the outer cylinder 3 to be in a closed state. When the cap 4 is rotated rearward with respect to the outer cylinder 3, as shown in FIG.
The opening of is opened. The cap 4 is constantly biased by the torsion coil spring 5 so as to rotate in the opening direction, that is, backward.

As shown in FIG. 4, a notch 12 is provided at the edge of the opening on the front surface of the peripheral wall of the outer cylinder 3. A ring 6 is rotatably attached to the outer peripheral portion of the peripheral wall of the outer cylinder 3 so as to cover the outside of the cutout 12.

As shown in FIG. 1, the front surface of the cap 4 is provided with a projecting piece 7 which is inserted into the inside of the ring 6 in the closed state and is fitted into the notch 12 of the outer cylinder 3. ing. The outer surface of the projecting piece 7 is provided with a recess 8 whose both ends in the lateral direction are open.

Further, on the inner surface of the ring 6, a convex portion 9 which can be inserted into or removed from the concave portion 8 of the protruding piece 7 of the cap 4 by the rotation of the ring 6 in the closed state of the cap 4. Is provided. When the ring 6 is rotated in the direction of the arrow in FIG. 3 and the convex portion 9 is fitted into the concave portion 8 of the protruding piece 7 of the cap 4 as shown in FIGS. 1 to 3, the cap 4 is locked. The rotation in the opening direction is blocked and the closed state is maintained. As shown in FIG. 3, a stopper 13 is also provided on the inner surface of the ring 6 so that the stopper 13 comes into contact with a step 14 provided on the outer tube 3 to limit the rotation of the ring 6. The ring 6 is positioned so that the convex portion 9 of the ring 6 just fits into the concave portion 8 of the protruding piece 7 of the cap 4.

Further, when the ring 6 is rotated in the direction of the arrow in FIG. 6 and the projection 9 thereof is removed from the recess 8 of the projecting piece 7 of the cap 4, the locked state of the cap 4 is released and the cap 4 is released. Since the force of the above spring 5 acts on 4,
The protruding piece 7 comes out of the notch 12 of the outer cylinder 3 and further rotates rearward to open the opening of the outer cylinder 3. Therefore, as shown in FIGS. 4 and 5, the marking surface 2 of the permeation mark 1 is exposed at the opening of the outer cylinder 3, and the marking can be performed as described above. At this time, the tapered surface 1 provided on the stopper 13 of the ring 6
5 rides on the tapered projection 16 provided on the outer cylinder 3, and the ring 6 is fixed by the friction.

[0012]

As described above, according to the present invention, since the cap 4 can be automatically opened by the force of the spring 5 by rotating the ring 6, the cap 4 opening operation at the time of marking can be extremely performed. The cap 4 is rotatably attached to the outer cylinder 3 and is not separated, so that the cap 4 can be prevented from being lost when the lid is opened. Further, if the guide cylinder 10 is arranged around the permeation mark 1 as in the above-mentioned embodiment, the permeation mark 1 can be obtained as described above.
Since the stamp surface 2 of 1 is parallel to the paper surface and is imprinted in that posture, there is an advantage that a good imprint can be obtained.
