Abstract
An ink cartridge or inkpad for use in a hand stamp in which the cartridge is made up of two parts. There is a frame portion and a central removed portion or well. Ink is deposited into the well and absorbed by the foam stamping member and the frame portion. In a first embodiment the central removed portion is reinserted back into the cartridge to provide additional ink storage medium and to impart structural strength to the stamping member. A trim ring supports the stamping member and locks the stamping member and ink cartridge into the stamp mount. This minimizes the mess associates with inking inkpads and also minimizes ink loss due to evaporation and drying. It also reduces the inventory of ink cartridges required by a stamp manufacturer as the cartridges are stored dry and the desired color ink is only placed in the ink cartridge when the stamp is manufactured for the user.
