Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamp capable of preventing accidental movement of an ink cartridge during transportation.

2. Description of the Related Art Conventionally, stamps have been widely used in various places such as to display company names, addresses, etc., to display product names, quality, etc., and to display inspection seals. In this case, the stamp includes an absorber type stamp in which an ink absorbing body impregnated with ink is built in the stamper, and a direct liquid type stamp in which a direct liquid type ink cartridge is built in the stamper.

In recent years, a service has been provided that allows customers to easily receive original stamps by using thermal processors installed in stores that sell the above-mentioned stamps to process stamp face patterns designed by customers on the spot. calling.
In this type of stamp, a printed body (stencil) is formed of a porous film. A thermal head of a processing machine processes the printed material with high precision into a stamped portion having a high ink penetration rate and a non-stamped portion having a low ink penetration rate. An ink occluding body or a direct liquid ink cartridge in the case abuts against the back surface of the printed body, thereby supplying ink to the printed body.
By the way, when the unprocessed printed body is impregnated with ink, it is difficult to control thermal processing, and there is a possibility that troubles such as contamination of members such as a thermal head and film may occur during processing. In order to prevent such a problem, the print body and the ink cartridge are held in a position where they do not come into contact with each other. There is a stamp and its manufacturing method. However, since the printed body is fitted into the case body, if an unexpected external force is applied during distribution in the market, the printed body and the case body will fit together, and as a result, the ink will not permeate into the printed body. Sometimes it started.

Further, in the case of a direct liquid type ink cartridge as disclosed in Patent Document 1, if the ink cartridge is shipped in a pre-installed state, the inside of the cartridge may be damaged due to sudden changes in pressure, temperature, etc. during air or land transportation. There is a risk that the internal pressure will rise and ink will leak. On the other hand, in order to avoid this, there is a method of shipping the ink cartridge and the stamp body separately. There is a problem that if the cartridge is subjected to strong vibration or the like and moves downward carelessly, the seal that seals the opening of the cartridge may be damaged, resulting in ink leakage.

Preferred embodiments of the present invention are described below with reference to the drawings.
FIG. 1 is a perspective view showing an example of a direct liquid type stamp according to the present invention, FIG. 2 is a front view thereof, FIG. 3 is a cross-sectional view along AA in FIG. 1, and FIG. 4 is a cross-sectional view along BB in FIG. . In the figure, 1 is a slide, 2 is a holder, and a stamp face 3 is housed in the slide 1 so as to move up and down. When the holder 2 is pressed down, the covers 4, 4 are opened, and the stamp surface 3 is lowered and exposed at the same time, so that the seal can be stamped. It is basically the same as a stamp. In the present invention, there is no problem in operation even without the holder 2, and in that case, a part of the ink cartridge plays a role of the holder.

The present invention is a direct liquid type stamp provided with a direct liquid type ink cartridge, and between the holder 2 and the slide 1, a cartridge fixture 21 for preventing movement of the ink cartridge 11 is detachably attached. installed. Here, the ink cartridge is defined as an ink reservoir, and includes not only a direct liquid cartridge but also an ink absorber. In this embodiment, the ink cartridge will be described as a direct liquid ink cartridge.
According to the present invention, by shipping the ink cartridge 11 and the stamp body separately, it is possible to prevent ink from being accidentally supplied to the stamp face 3 during transportation or from leaking due to environmental changes during transportation. However, the cartridge fixture 21 keeps the ink cartridge 11 and the stamp face 3 apart, and the consumer removes the cartridge fixture 21 to separate the stamp face 3 and the ink cartridge 11 before use. The technical problem is to simultaneously solve the two problems of facilitating communication and starting the use of the stamp. For this reason, the present invention employs a structure in which the cartridge fixture 21 is detachably attached.

As shown in FIG. 5, the cartridge fixture 21 is composed of a plate-shaped holder downward movement prevention piece 22 that prevents the holder 2 from downward movement.
That is, the holder 2 is pushed down by mounting the plate-shaped holder downward movement prevention piece 22 between the lower end portion of the holder 2 as the engaging piece 2a and the stepped portion as the engaging portion 1a of the slide 1. Even if it does, it will not be able to move downwards. As a result, since the ink cartridge 11 is not pushed down, the sealing seal 12 at the opening is not broken by the protrusion 5 and ink leakage does not occur. The protrusion 5 is a cylindrical tube provided on the stamp face 3, and has a sharp tip. When the ink cartridge 11 is lowered, it breaks the seal 12 and also serves as an ink introduction tube for introducing ink to the stamp face 3. ing. Here, the ink cartridge 11 may be integrated with the holder 2. In this case, the holder downward movement prevention piece 22 is the engagement piece 2a at the lower end of the ink cartridge, and serves as the engagement portion 1a of the slide 1. and the stepped portion of the ink cartridge to prevent downward movement of the ink cartridge.

As shown in FIG. 5, the cartridge fixture 21 comprises a claw-like cartridge anti-vibration piece 23 that prevents the ink cartridge 11 from vibrating. The cartridge anti-vibration piece 23 is composed of two claws that hold the ink cartridge 11 in the direction perpendicular to the axial direction thereof.
The cartridge anti-vibration piece 23 fixes the ink cartridge 11 by inserting the two claws into the groove 13 (see FIGS. 6 and 7) of the ink cartridge 11, and prevents an unexpected impact from occurring during transportation. Even if force is applied, the ink cartridge 11 is prevented from swinging to the left and right.

Further, as shown in FIG. 5, the cartridge fixing member 21 includes a plate-like holder downward movement prevention piece 22 that prevents the holder 2 from moving downward, and a claw-like cartridge rocking prevention piece that prevents the ink cartridge 11 from rocking. Preferably both strips 23 are provided.
In this case, since the ink cartridge 11 is not pushed down, the opening seal 12 is not broken by the ink introduction pipe 5 and ink leakage does not occur. In addition, since the ink cartridge 11 does not oscillate or move in the axial direction, the seal 12 of the ink cartridge 11 will not be damaged and ink will not leak, which is preferable.

The attachment/detachment operation of the ink cartridge of the present invention will be described below.
First, when shipping the direct liquid type stamp of the present invention, the ink cartridge 11 sealed with the seal 12 is temporarily set in the holder 2 , and the holder 2 is incorporated into the slide 1 . Further, the cartridge fixture 21 is mounted at a predetermined position, and the downward movement of the holder 2 is prevented by the plate-shaped holder downward movement prevention piece 22, and the ink cartridge 11 is prevented from rocking by the claw-shaped cartridge oscillation prevention piece 23. do. This reliably prevents ink from leaking during transportation.

Next, when the consumer uses the direct-liquid stamp after purchase, the cartridge fixing member 21 is removed for use, and the cartridge fixing member 2 can be simply pulled out. Next, when the holder 2 is pushed down in the same manner as for stamping, the ink cartridge 11 is also lowered, and the sealing seal 12 at the opening is broken by the ink introduction pipe 5, and ink is supplied to the stamp surface 3. After that, the stamping process can be continuously performed in the same manner as the normal stamping.

As is clear from the above description, the present invention is a stamp provided with a slide that accommodates the surface so that it can move up and down, and an ink cartridge that is set above the stamp surface, wherein between the ink cartridge and the slide, Since the cartridge fixture for preventing the downward movement of the ink cartridge is detachably attached, it is possible to prevent the ink cartridge and the stamp body from being shipped separately and causing ink leakage during transportation. can. Also, when using the product, the consumer can start using it by a simple operation of removing the cartridge fixture and connecting the stamp face and the ink cartridge. Furthermore, in the case of the direct liquid type stamping, a large amount of stamping processing can be performed, the ink cartridge can be easily replaced, and there is also the advantage of being excellent in cost performance.
