Abstract
A liquid discharge head switchable manually between secured and released states. In the secured state, liquid discharge is prevented, and in the released state, liquid discharge is enabled. The discharge head has a discharge channel and a discharge opening at an end of the discharge channel. Further, an outer shell is provided and has a discharge aperture through which the liquid delivered through the discharge opening is discharged. For switching purposes, the outer body has, internally in relation to the outer shell, a rotatable inner or screen body. A releasable snap-action coupling is provided, by which the outer shell and the inner body are coupled rotationally in a closed rotational position such that an open rotational position is reached again only after manual application of force to a release surface of the coupling.
