[0002]

[Prior art]

 Conventionally, there has been known a seal stamp that does not need to be adhered to the red meat and the like each time it is used, using a printing body formed of a multi-pore printing material having a large number of continuous pores such as sponge rubber so that it can absorb ink. Has been. This type of seal, which is commercially available, is composed of an ink storage material impregnated with ink and a printing material, and when the usage frequency is high, the ink runs out quickly and it is necessary to replenish the ink each time. Further, there is a drawback that the print density becomes thinner as the number of markings increases. In addition, when replenishing the ink, a large amount of ink cannot be replenished at one time because the ink is dropped and impregnated on the printing surface with a dropper or the like, which is troublesome. In addition, it takes time for the printing surface to be uniformly impregnated with the sticky ink. Further, when the ink is dropped, the ink overflows from the printed surface and stains the hands and the surroundings. Then, as a method for solving such drawbacks and problems, Japanese Utility Model Publication No. 61 23410 discloses a method of replenishing ink from an ink cartridge by using an ink flow rate adjuster such as a writing instrument. There is. However, the structure using the above ink flow rate adjuster has a complicated structure and is difficult to provide at low cost.
