Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stamp having a function of preventing ink leakage and ink volatilization when not in use.
[0002]
[Prior art]
Stamps that are fitted with a cap to prevent volatile ink from volatilizing from the printing surface at the lower end of the stamp body are widely known by Japanese Utility Model Nos. 60-21237 and 2-34054. Yes. These have the effect of preventing volatilization by interposing a seal member on the contact surface between the cap and the stamp body, but since they need to be in close contact with each other, they can be fitted with a uniform force such as screw fitting. It was necessary to take a configuration, so there was only a round stamp.
Therefore, the present applicant has proposed pinching and fitting with a hook member in ACT No. 7-9657, in which the cap and the stamp body are brought into close contact with each other to achieve airtightness, and polygonal stamps other than round stamps also volatilize ink. A stamp having a preventive effect could be obtained.
However, in actual fairness 7-9657, a slight difference in fitting force occurs between the portion where the hook member of the hook member is present and the portion where the hook member is not present, and the ink volatilizes through a very small gap between the contacts, Such a seal cannot completely prevent the ink from volatilizing, and the ink volatilizes over time.

[Problems to be solved by the invention]
The problem to be solved by the present invention is that it eliminates the disadvantages of conventional stamps as described above, and the seal member exhibits an excellent sealing effect and can completely prevent ink volatilization even when volatile ink is used. Is to provide.
[0005]
[Means for Solving the Problems]
The stamp of the present invention which attempts to solve the above-described problems is formed by extending a collar portion on the lower peripheral surface of the holder and continuing a print body storage cylinder portion containing a porous print body below the holder. And the stamp body
An inner cap provided with a seal member housing groove on the upper end surface and loaded with the seal member, and holding the inner cap up and down via an elastic body, and opening and closing the hook member having a claw portion on the opposite side surface A cap composed of an outer cap that is connected to the cap; and
A stamp consisting of
When the claw portion of the hook member engages with the collar portion of the holder and the stamp body and the cap are fitted , the seal member reaches the lower end of the collar portion, and the porous printed body can be sealed. It is what.

【Example】
Next, the present invention will be described in detail with reference to the illustrated embodiments.
The stamp of the present invention comprises a stamp body 1 and a cap, which will be described in detail below. Reference numeral 1 denotes a printing body in which a printing body storage cylinder portion 4 is connected to a lower part of a substantially rectangular parallelepiped holder 3. A lid 2 with a display label is fitted to the upper end opening of the holder 3, and a printing body storage cylinder portion is provided. 4 contains a porous printed body 5 and, if necessary, an ink occluding body 6. A flange 7 is integrally stretched on the lower peripheral surface of the holder 3. In the embodiment, a partition is provided in the middle part of the holder 3, an ink replenishing port 8 and a spring 9 are installed, and the porous printing body 5 and the ink storage body 6 are accommodated under the spring of the spring 9.
Reference numeral 20 denotes a cap including an inner cap 21 and an outer cap 22. A seal member storage groove 23 is formed on the upper peripheral surface of the inner cap 21, and a seal member 24 is loaded in the seal member storage groove 23. The seal member 24 is a ring-shaped ring body mainly made of silicone rubber, and has a series of ridges formed on the upper surface thereof. The ridges are projected from the seal member housing groove 23 and loaded. is there. A pair of hook members 26 each having a claw portion 25 formed at the upper end are disposed on the opposite side surfaces of the outer cap 22, and the hook members 26 are connected to the bottom surface portion 27 of the outer cap 22 at several connecting portions 28. And it is integrally molded. The hook member 26 and the bottom surface portion 27 are connected to each other so as to be able to be opened and closed by forming a connecting portion 28 so that an elastic force is applied.
The cap 20 is composed of the inner cap 21 and the outer cap 22, but an elastic body 29 is installed between the inner cap 21 and the outer cap 22, and the inner cap 21 can be moved up and down via the elastic body 29. It is held by the outer cap 22. Further, both of the caps 30 can be moved up and down between the inner cap locking part 30 formed on the lower surface of the inner cap 21 and the outer cap locking part 31 formed on the inner surface of the outer cap so that they cannot be separated. Is engaged. In the embodiment, the cap 20 is configured in this way so that the inner cap and the outer cap are not separated from each other by the locking portion while the inner cap is always repelled upward due to the elastic body 29. It has stopped. Further, by arranging a plurality of elastic bodies at appropriate positions, the inner cap is repelled upward with a uniform and strong force.
To attach the stamp body 1 to the cap 20, the holder 3 is held and inserted from the upper surface of the cap 20. At first, the collar portion 7 of the holder 3 comes into contact with the claw portion 25 of the hook member 26. When the thrust member 7 is further pushed against the elastic force of the hook member 26, the hook member 26 is pushed and spread over the claw portion 25. The member 26 comes into contact with the collar receiver 32 provided on the member 26 and stops. At this time, the hook member 26 returns to the original position by the elastic force, the claw portion 25 engages with the collar portion 7, and the stamp body 1 and the cap 20 are fitted.
In such a configuration, the inner cap 21 is held by the outer cap 22 so as to be movable up and down via an elastic body 29. Since the seal member 24 reaches the lower end of the flange portion 7 and can completely block the inside of the cap 20 from the outside, even when the porous print body 5 is impregnated with volatile stamp ink, the porous print body The volatilization of the ink from 5 can be completely prevented.
When using the seal, if the operation part of the pair of hook members 26 of the outer cap 22 is pressed against the elastic force of the connecting part 28, the hook member 26 is opened, and the claw part 7 of the hook member 26 and Since the engagement with the collar portion 7 of the holder 3 is released, the cap 20 is removed, and the porous printed body 5 is exposed in a state in which an appropriate amount of stamp ink has been leached in order to carry out the printing. Similarly, the stamping operation may be performed by holding the holder 3.
In the embodiment, the porous printing body 5 and the ink occluding body 6 are accommodated in the printing body accommodating cylinder 4, but it is not necessary to use the ink occluding body 6. Further, in this embodiment, since the ink replenishing port 8 is provided in the middle part of the holder 3, the ink can be replenished without removing the print body storage cylinder 4, which is convenient for ink replenishment. It will be something. Further, since the spring 9 is installed in the middle part of the holder 3 and the porous printing body 5 and the ink storage body 6 are accommodated under the spring of the spring 9, the cushioning property at the time of stamping can be improved.
[0007]
【effect】
In the present invention, since the inner cap is always elastically bulged upward by the elastic body, the sealing member can press the collar portion of the holder with a uniform and strong force, and the inside of the cap is completely blocked from the outside. It is possible. Therefore, even when volatile stamp ink is used, it is possible to prevent volatilization of the ink from the porous printed material accurately and easily. It ’s a big one.
