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. A pre-inked ink cartridge 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 die box is then inserted into the hand stamp. A method of manufacturing the die box is also disclosed.
