Abstract
Abstract A disposable ink cartridge is provided comprising a container having a top opening, an inwardly extending bottom and an inwardly extending shoulder or rim. An ink absorbent pad such as a sponge is fitted inside the container followed by an ink distributing pad such as a felt pad. The container is sealed by a laminate consisting of a bottom layer of metal foil having a heat sealing polymeric composition on its undersurface and a top layer of paper such as kraft paper. The felt pad has a hole located therein which equalizes the pressure between the surface of the felt and the inside of the cartridge.
