发明名称 Self-inking stamp with ink cartridge barrier
摘要 A stamp pad holder for use in a self-inking hand stamp. The stamp pad holder has a stamp die box that holds a stamp forming material, ink cartridge and plastic within the die box. The stamp forming material is placed at the bottom of the die box. An ink cartridge having a layer of soft, compressible, ink permeable material applied to its bottom surface is placed above the stamp forming material but separated by an impermeable film. The film prohibits ink from flowing from the ink cartridge to the stamp forming material until the film is pulled from the die box prior to use. This permits the ink from the ink cartridge to impregnate the stamp forming material. The soft, compressible, ink permeable material increases the rate of ink flow from the ink cartridge to the stamp forming material.
