Abstract

(57) [Summary] [PROBLEMS] To provide a cover that can be firmly fixed to a cylindrical portion on the tip side of a mark. SOLUTION: An annular concave groove 11 is formed on the peripheral surface of a cylindrical portion 13 on the tip side of a mark 1. The cylindrical portion 13 is the size of the diameter of the stamp surface 12. The O-ring 3 is fitted and attached to the concave groove 11. When the cover 2 is fitted to the cylindrical portion 13 of the mark 1, the O-ring 3 is elastically deformed and the O-ring 3 and the cover 2
Are brought into close contact with each other to generate a contact force.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of a stamp, and more particularly to a structure of a stamp with a cover for covering a stamp surface.

[0002]

[Problems to be solved by the invention]

 The marking tool with a cover that covers the stamping surface has a configuration in which the cover is fitted to the cylindrical portion on the tip side of the marking. In the conventional marking tool, the fixing of the cover to the mark depends exclusively on the fitting of the cover to the mark, and the degree of fixing is weak, and the cover may come off during handling.

[0003] In addition, it was difficult to manufacture the cover so that the degree of fitting to the mark was moderate. Therefore, the present invention is to provide an improved stamp structure which solves the above-mentioned problems.

[0004]

[Means for Solving the Problems]

 The invention according to claim 1 comprises a mark and a cover; the mark has an annular groove formed on a peripheral surface of a cylindrical portion having a mark surface at a tip, and an O-ring is fitted and attached to the groove. Yes, when the cover is fitted to the cylindrical portion of the mark, the O-ring is elastically deformed to generate a contact force for bringing the O-ring into close contact with the cover.

[0005] Since the elastically deformed O-ring and the cover are in close contact with each other to obtain a contact force, it is difficult for the cover to be unnecessarily removed from the mark. Therefore, the cover does not come off during the handling of the stamp. Further, since the contact force is obtained by the elastic deformation of the O-ring, it is not necessary to increase the accuracy of the inner diameter of the cover and the diameter of the cylindrical portion of the mark, thereby facilitating the manufacturing.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The structure of a stamp according to an embodiment of the present invention will be described below. FIG. 1 is an exploded view of a stamp 100 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the stamp with a cover. The stamp 100 includes a mark 1 and a cover 2.

The mark 1 has an annular concave groove 11 formed on the peripheral surface of a cylindrical portion 13 having a mark surface 12 at the tip. The cylindrical portion 13 is the size of the diameter of the stamp surface 12. An O-ring 3 is fitted and attached to the concave groove 11. When the cover 2 is fitted on the cylindrical portion 13 of the mark 1, the O-ring 3 is elastically deformed as shown in FIG. Due to the frictional force that can be generated by this contact force, the cover 2 is firmly attached to the mark 1 so as not to come off easily.

The cover 2 covers the stamp surface 12, and the stamp surface 12 is housed inside the cover 2. Therefore, the user's clothes are prevented from being stained by the vermilion attached to the stamp surface 12 by removing the cover 2. Also, when the cover 2 is fitted to the mark 1, the dimensional difference between the cover 2 and the mark 1 is absorbed by the elastic deformation of the O-ring 3. Therefore, the dimensional accuracy required for the inner diameter of the cover 2 and the diameter of the cylindrical portion 13 of the mark 1 is relaxed.

FIG. 3 shows a stamp 110 according to another embodiment of the present invention, in which the mark 1 with the cover 2 removed and the cover 2 with the cover 2 removed face each other. The stamp 110 includes a mark 1 and a cover 2 that covers the mark surface 12 of the mark 1. The cover 2 has a stamp face 21 on the outside. The font and content of the stamp face 21 of the cover 2 are different from the font and content of the stamp face 12 of the mark 1.

Therefore, the stamp 110 can be stamped using the stamp face 21 of the cover 2 in addition to the stamp stamp using the stamp face 12 of the stamp 1. That is, the user can press two kinds of marks by carrying one mark 110. FIG. 4 shows a marking tool 120 according to another embodiment of the present invention, in which the mark 1 with the cover 2 removed and the cover 2 with the cover 2 removed face each other. This is shown with the cover 2 removed.

The mark 1 and the cover 2 are tied together as an ornament. Therefore, the stamp 120 is likely to be collected and stored. The present invention is not limited to the above-described embodiment, and the scope of the invention and the scope of equivalent changes and modifications described in the claims for utility model registration are also included in the scope of the right.

[0012]

[Effect of the invention]

 As described above, in the invention of the present application, the O-ring is fitted and attached to the annular concave groove on the peripheral surface of the cylindrical portion on the tip side of the mark, and when the cover is fitted to the cylindrical portion of the mark, the O-ring is formed. The structure is such that the O-ring and the cover are elastically deformed to generate a contact force that makes the O-ring and the cover adhere to each other. Therefore, the cover can be made hard to come off from the mark. It can be prevented that it comes off. Further, since the contact force is obtained by the elastic deformation of the O-ring, it is not necessary to increase the accuracy of the inner diameter of the cover and the diameter of the cylindrical portion of the mark, thereby facilitating manufacture.
