Abstract
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.
Claims26
A stamp pad holder for use in a self-inking hand stamp comprising:
- a stamp die box having a top, a bottom and opposite sides,
- a stamp forming material mounted at the bottom of the die box, the stamp forming material having an ink receiving side and an image forming side,
- a pre-inked cartridge mounted in the stamp die box adjacent to the ink receiving side of the stamp forming material, and
- a non permeable film disposed between the pre-inked cartridge and the ink receiving side of the stamp forming material for prohibiting the flow of ink from the pre-inked cartridge to the stamp forming material until the film is removed from between the pre-inked cartridge and the stamp forming material at which time the ink can flow from the pre-inked cartridge to the stamp forming material thereby impregnating the stamp forming material with ink.
A stamp pad holder for use in a self-inking hand stamp comprising:
- a frame member having a top, bottom and opposite sides, and adapted to be received by a hand stamp;
- a stamp forming material mounted at the bottom of the frame member, the stamp forming material having an ink receiving side and an image forming side,
- a pre-inked cartridge contained within a non permeable bag, the bag disposed within the frame member adjacent to the ink receiving side of the stamp forming material,
- the non permeable bag having a removable side adjacent to the ink receiving side of the stamp forming material, and
- means for removing the removable side of the non-permeable bag for allowing ink to pass from the pre-inked cartridge to the stamp forming material thereby impregnating the stamp forming material with ink.
A stamp pad holder for use in a self-inking hand stamp comprising:
- a stamp die box having a top, a bottom and sides,
- a stamp forming material mounted at the bottom of the die box, the stamp forming material having an ink receiving side and an image forming side,
- a framing member mounted inside the die box adjacent to the sides, the framing member having a thickness.
- a pre-inked cartridge mounted in the framing member and separated from the sides by the thickness of the framing member, the pre-inked cartridge adjacent to the ink receiving side of the stamp forming material, and
- a non permeable film disposed between the pre-inked cartridge and the ink receiving side of the stamp forming material for prohibiting the flow of ink from the pre-inked cartridge to the stamp forming material until the film is removed from between the pre-inked cartridge and the stamp forming material at which time the ink can flow from the pre-inked cartridge to the stamp forming material thereby impregnating the stamp forming material with ink.
20 The stamp pad holder of claim 19 wherein the non permeable film has two opposed ends, one end releasably mounted within the stamp die box and the other end protruding out from the exit means.
A method of impregnating a stamp forming material with ink for use in a hand stamp comprising the steps of:
- providing a die box with an open bottom,
- inserting and securing a stamp forming material at the open bottom of the die box,
- placing an impermeable film on top of the stamp forming material, placing an ink cartridge that is impregnated with ink on top of the impermeable film,
- enclosing the die box so that the ink cartridge, film and stamp forming material are contained within the stamp die box, and
- withdrawing the film allowing the ink from the ink cartridge to flow into the stamp forming material thereby impregnating the stamp forming material with ink.
A method of making a stamp die box for use in a self-inking hand stamp comprising:
- providing a die box frame with an open top and open bottom and continuous sides,
- inserting a stamp forming material at the open bottom of the die box frame,
- placing an impermeable film on top of the stamp forming material,
- placing an ink cartridge into a framing member, the framing member surrounding the perimeter of the ink cartridge,
- placing the ink cartridge and framing member into the die box frame on top of the impermeable film, the framing member keeping the ink cartridge out of contact with the sides of the die box frame, and
- covering the open top of the die box frame so that the ink cartridge, framing member, film and stamp forming material are contained within the stamp die box frame.
