Abstract

An ink cartridge for an inkjet printing system, having an extraction opening closed off by a membrane that is made of thermoplastic elastomer and that can be pierced by a hollow needle when inserted into the inkjet printing system. In order to ensure that the hollow needle penetrates with certainty in the short insertion path available in the dome, the membrane is made of a thermoplastic elastomer that has an elongation at tear that is reduced by the addition of inelastic, inorganic substance.
