Claims13
A hand stamp comprising a holder means which includes an ink storing space and a stamping member connected to said holder means, said stamping member being made of an open-cell foam material partially heat sealed to form an ink impermeable area with a remainder area for ink permeation to effect a stamping, said ink impermeable area defining intaglio portions formed by press in the heat sealing and said ink permeable portions defining relief portions, and wherein said relief portions collectively define an image that is transferred to a surface when the hand stamp is pressed against such surface.
A hand stamp comprising a holder which includes an ink storing space and a stamping member connected to said holder, said stamping member being made of an open-cell foam material partially heat sealed to form an ink impermeable area with a remainder area for ink permeation to effect a stamping, said ink impermeable area defining intaglio portions formed by press in the heat sealing and said ink permeable portions defining relief portions for the stamping, wherein said stamping member and said holder are made of the same polyolefin resin, and said stamping member and said holder are heat sealed at a boundary in the outer surface of said stamping member which boundary contacts said holder for preventing ink from leaking from the boundary.
