Abstract

(57) [Summary] [Purpose] A seal with numerous continuous ventilation holes made of sponge rubber etc. that does not require vermilion. To solve the problem of staining hands and clothes when cleaning. [Structure] A stamp 20 is attached to the front end of the shaft tube 1, and the lid part 3 that always shields the opening 17 is elastically rotated by forming a hinge with an elastic piece 4 having spring properties at the rear end of the cap 2. In addition to being attached movably, the cap 2 is fitted onto the barrel 1 so that it can move axially, and when the cap 2 is moved to the rear of the barrel 1, the cover 3 contacts the corner of the stamp 20 and expands. Open it and

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is equipped with a seal that uses a printing body made of a porous stamp material with countless continuous pores. Regarding the improvement of the so-called opening/closing seal stamp mentioned above.

0002

[Conventional technology]

Conventionally, polyurethane materials with countless continuous pores, such as sponge rubber, were used to absorb ink. When using a printed body made of porous stamp material, it is necessary to attach it to ink, etc. each time it is used. Seals that are unnecessary are known. However, with this type of seal, the printing surface is exposed. Otherwise, the printed surface may be scratched, dust may adhere, or the ink may dry out. To avoid this problem, the printing surface is covered with a cap, and therefore Not only is it troublesome to put on and take off the cap, but there are also problems such as losing the cap. There are problems such as accidentally getting your hands dirty when putting it on and taking it off.

0003

[Problem that the idea aims to solve]

This invention aims to provide a convenient retractable seal that solves the above problems. It is.

0004

[Means to solve the problem]

The retractable seal of the present invention was devised to achieve the above purpose. Attach the seal and attach the lid that covers the opening so that it can rotate freely on the side of the rear end of the cap. At the same time, the cap is fitted onto the outer periphery of the shaft cylinder so that the cap can be moved axially. When the cylinder is moved to the rear, the inner surface of the lid touches the corner of the stamp and expands to form the stamp. The font is configured so that it is exposed through the opening and can be stamped.

[0005]

【Example】

1 and 6 show an embodiment of the present invention. First, as shown in Figure 5, the seal 20 is is a porous stamp made of sponge rubber or other material with numerous continuous ventilation holes so that it can absorb ink. The printed body 21 made of material and ink are stored and the ink is supplied to the printed body 21. The ink storage body is fixed to the leg part with a cover (not shown), and the front part of the shaft cylinder 1 is It is removably fitted to the tip of a shaft tube 1 provided in an inner hole.

[0006] The cap 2 is made of synthetic resin with excellent hinge characteristics, and is shown in FIGS. 3 and 5. As shown in FIG. If a slit 8 is formed approximately in the center of the connecting portion between the lid part 3 and the cap 2, An elastic piece 4 imparted with elasticity is bridged between the lid part 3 and the cap 2 so as to be rotatable. They are connected by hinges 5 and 6, and hinges 7 are rotatably formed on both sides of the connection part. It is. As described above, the lid part 3 is in a state where the opening 17 of the cap 2 is given spring properties. The lid part 3 is provided so as to be able to rotate freely to open and close in the state, and the lid part 3 always covers the opening part 17. is configured to do so.

[0007] In addition, the cap 2 is fitted onto the outer circumference of the shaft cylinder 1 so as to be axially movable; An elastic piece 13 is attached to the center outer circumferential part, and a support part 14 formed in the center of the elastic piece 13 supports the shaft cylinder 1. The elastic piece 13 is integrally connected to the elastic piece 13, so that the front and rear portions of the elastic piece 13 are movable. Also, elastic piece The front end 16 of 13 is formed with an upper part 18 that bulges out on the upper surface, and the rear upper surface has a protrusion. It is formed.

[0008] Furthermore, a slit 19 is provided on the side surface of the cap 2 at a portion corresponding to the elastic piece 13. The front end surface of the hole is formed as the abutment part 11, and the step part 12 is formed on the inside of the abutment part 11. An elastic piece 9 is displaceable toward the rear of the cutter 19, and a knob 10 is formed at the tip of the elastic piece 9. ing. Also, in order to position the cap 2 and the barrel 1, it is necessary to stop them from rotating. There is. There are various ways to prevent each other from rotating, but this is not covered by this invention. Since this is not the gist of the article, the explanation will be omitted. In addition, a writing instrument is mounted on the rear end of the barrel 1, so-called It is also possible to configure a writing instrument with a seal.

[0009]

[Effect]

The retractable seal of this invention is constructed as described above, and when not in use, it is shown in Figures 1 and 2. As shown in FIG. 3, the cover 3 covers the printed body 21. When stamping, elastic Suitably press the knob 10 of the piece 13 inward so that the tip 16 contacts the abutment part 11 of the cap 2. Move the cap 2 backward with respect to the shaft cylinder 1 while avoiding contact with the cylinder (see Fig. 4). With the hinge 7 as a fulcrum, the lid part 3 is attached to the stamp 20 with its inner surface avoiding the printed body 21. The stamp 20 is exposed from the opening 17 of the cap by expanding the seal while touching the corner. At that time, the protrusion 15 of the elastic piece 13 engages with the stepped portion 12 of the cap 2 and is positioned. It is constructed so that it can appropriately withstand the pressure applied during sealing. (See Figures 5 and 6) Seal again 20, the cap 2 may be moved forward with respect to the barrel 1. At this time, the tip 16 of the elastic piece is in contact with the abutment part 11 of the cap, and Even if pressure is applied to the cap 2 in the axial direction, the lid portion 3 does not expand.

[Effect of the idea]

The structure and operation of the retractable seal stamp of the present invention are as described above, and it is different from the conventional removable seal stamp. If the printing surface is coated with a cap, you may have to remove and remove the cap every time you stamp it and lose it. There is no need to worry about it getting stuck, and there are no problems such as accidentally getting your hands dirty when putting on and taking off the cap. In addition, the printing surface is covered by the lid when not in use, so it is easy to use. There are no problems such as scratches, dirt, or dry ink, and it is extremely easy to use. We can provide a seal that is easy to use. Also, the lid part is connected to the cap with a hinge. Since it is a synthetic resin part, it also has the advantage of being able to be provided at a low cost.
