Abstract

PROBLEM TO BE SOLVED: To refill ink by proper quantities by simple operation so as not to make the ink excessive. SOLUTION: On the inside face of a pipe body 3 having an inner hole as an ink housing space 4, partition protrusions 5 which are vertical to the axial direction are arranged at regular intervals in the axial direction. A quantity of an ink 6 equivalent to a refill quantity for one time is charged in between each of the partition protrusions 5 and its adjacent partition protrusion 5. Inside the pipe body 3, an ink protruding plug 7 which moves in the axial direction when it is pressed, can stop once when it abuts against the partition protrusion 5, and can get over the partition protrusion 5 with elastic deformation when it is pressed by stronger force is mounted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal for replenishing ink into an ink impregnated body, which is mounted on a seal having ink penetrated therein and an ink impregnated body for supplying the ink to the stamp body. The present invention relates to an ink cartridge.

[0002]

2. Description of the Related Art When the amount of ink held by an ink impregnated body decreases, the ink supplied to a stamp body tends to be interrupted.
The shadow imprinted by the stamp body becomes thin. Therefore, it is necessary to replenish the ink impregnated body from time to time. Conventionally, as a method of replenishing ink, a method of directly dropping raw ink from an ink bottle to an ink impregnated body, a method of using a disposable type ink cartridge filled with raw ink only for one replenishment, an ink of sponge, etc. There is a method using an ink cartridge made of a material impregnated with the ink.

[0003]

In the above-mentioned method, it is difficult to drop an appropriate amount of ink, and the amount of dropping tends to be too large. There is a problem that the ink which cannot be completely absorbed into the ink stains the surroundings. In the above method, since the ink cartridge is a disposable type, it is difficult to determine when to use the ink cartridge.
Further, all the ink is used up to be discarded after use.However, since this type of ink cartridge is generally filled with a relatively large amount of ink, the amount of ink supplied tends to be excessive. There is a problem similar to the method of the above. Also, in the above method, the ink cartridge is impregnated with ink, so that the ink holding amount is smaller than that of a type of ink cartridge that is directly filled with raw ink, and a plurality of ink cartridges are required to obtain the required ink amount. There is a problem that it becomes necessary and expensive.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to supply an appropriate amount of ink so as not to become excessive.
Further, it is an object of the present invention to provide a seal ink cartridge which is not expensive and can be easily replenished.

[0005]

The above object is achieved by the present invention, that is, a partition projection 5 perpendicular to the axial direction is fixed in the axial direction on the inner surface of a pipe body 3 having an inner hole as an ink containing space 4. The space between the partitioning projections 5 and the adjacent partitioning projections 5 are filled with ink 6 in an amount corresponding to a single supply amount, and the inside of the pipe body 3 is pressed. In this case, the ink push-out plug 7 which can be temporarily stopped when it moves in the axial direction and comes into contact with the above-mentioned partitioning projection 5, and which can be pushed over the partitioning projection 5 by elastic deformation when pressed by a stronger force. The problem can be solved by a seal ink cartridge that is mounted.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. First, FIG. 1 shows an ink cartridge 1 and a tail plug 2 for attaching the ink cartridge 1 to a seal body 10. The ink cartridge 1 is made of transparent plastic, and has an elongated pipe shape as a whole. In the ink cartridge 1, the inner hole of the pipe body 3 is defined as an ink storage space 4, and the ink storage space 4 is partitioned by a plurality of partitioning projections 5 perpendicular to the axial direction. The partitioning projections 5 are formed in the circumferential direction, and the partitioning projections 5 keep a constant interval in the axial direction. The ink accommodating space 4 is filled with the ink 6, and the amount of ink filled between one partitioning protrusion 5 and the partitioning protrusion 5 adjacent thereto is an amount corresponding to one supply amount. The amount of replenishment for one time is 0.1 g to 0.2 g or less, which is an amount that allows 500 to 1000 times of stamping.

[0007] Inside the pipe body 3, an ink push-out plug 7 that can move in the axial direction when pressed is mounted.
The ink push-out plug 7 has substantially the same length as the interval between two adjacent partitioning projections 5, and its outer diameter is slightly larger than the inner diameter of the partitioning projections 5. Note that the outer peripheral surface of the ink push-out plug 7 is almost in contact with the inner peripheral surface of the pipe body 3. When the ink push-out plug 7 moves forward, the peripheral edge thereof comes into contact with the partitioning projection 5 to be in a locked state and temporarily stops. However, when pressed with a stronger force, the partitioning projection 5 is elastically deformed and can move over. A hole 8 is provided on the rear surface of the ink push-out stopper 7. The ink 6 filled in the pipe 3 has a relatively high viscosity, and does not flow out naturally from the opening at the front end of the pipe 3 unless pushed out by the ink push-out plug 7.

[0008] As shown in FIG. 2, the ink cartridge 1 is assembled with the tail plug 2 and mounted on the seal body 10. That is, the ink cartridge 1 has its pipe 3
Is attached by inserting the tail plug 2 into the rear end portion of the seal body 10. A flange 9 for receiving the tail plug 2 protrudes from a rear end outer peripheral portion of the pipe body 3 of the ink cartridge 1. Note that FIG.
In the figure, reference numeral 11 denotes a cap that covers the stamp surface, and reference numeral 12 denotes a shaft cover that covers the ink cartridge 1.

Next, FIG. 3 shows a state in which ink is supplied. After removing the shaft cover 12 from the seal body 10 to expose the rear end of the ink cartridge 1, a thin rod 13 is inserted into the inside of the pipe body 3 of the ink cartridge 1 from the rear end opening, and the rod 13 The leading end is fitted into the hole 8 on the rear surface of the ink push-out plug 7, and the rod 13 is pressed forward. After the ink push-out stopper 7 advances over one partitioning projection 5, it comes into contact with the partitioning projection 5 in front thereof and temporarily stops. At this time, the pressing operation is stopped. As a result, an amount of ink corresponding to one replenishment amount is accurately extruded and supplied to an ink impregnated body (not shown) built in the seal body 10.

[0010]

The ink cartridge for seals of the present invention is as described above. By providing the partitioning projections 5 at regular intervals inside the pipe body 3 filled with the ink 6, the ink ejecting plug 7 can be moved at regular intervals. Move forward and ink 6 each
Can be accurately pushed out from the pipe body 3 and replenished, so that the adverse effect of an excessive amount of ink replenishment, that is, the adverse effect of blurring of the seal imprint or contamination of the surroundings by ink that cannot be completely absorbed can be prevented. . In addition, the replenishment operation is simple because the ink push-out stopper 7 may be pressed with the stick 13 or the like. In addition, the ink is not used up by one replenishment, but can be replenished many times by installing once, so that there is little trouble in mounting and removing. Also, since it is a type that is filled with raw ink as it is, there is no shortage of ink supply amount, and multiple ink cartridges are required to obtain the required amount of ink like the type that is impregnated and held. There is no disadvantage of being expensive.
