Abstract
This invention relates to a pierceable sealing element for a liquid outlet, especially an ink outlet opening of an ink reservoir in inkjet printing means, and an ink reservoir with one such sealing element which has a membrane which can be pierced by a hollow needle for removing liquid, and the hollow needle can be surrounded sealed from the outside by the pierced seal element. To form an improved seal with low production and installation cost it is proposed as claimed in the invention that the membrane is surrounded by an annularly peripheral sealing profile which can be twisted in the manner of a torus at least partially around a peripheral line when the membrane has been pierced, a sealing surface which runs radially on the inside being formed.
