Abstract: A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

Abstract: The invention relates to an extracting and dosing valve for a device for discharging spray media, comprising: an extraction piston having a longitudinal axis that comprises an extraction-piston actuating region and an axially oppositely arranged extraction-piston end region; an extraction orifice comprising a passage opening in which the extraction piston is arranged so as to be movable linearly, the extracting and dosing valve having a closed state that corresponds to a defined position of the extraction piston; and a first sealing element arranged adjoining the extraction-piston end region on the actuating region side, wherein the first sealing element closes the passage opening when the extracting and dosing valve is in the closed state.

Abstract: A capsule holder for holding a gas capsule for an apparatus for output of an output medium includes a gas capsule holder element configured as a deep-drawn part having an opening for holding the gas capsule. A cover configured essentially in the manner of a sleeve surrounds the gas capsule holder element from the outside, at least in certain sections. The capsule holder includes a threaded ring configured as a separate element, having an inside thread and/or an outside thread, wherein the threaded ring is firmly connected with the gas capsule holder element and arranged in the region of the opening, so as to make introduction of the gas capsule into the gas capsule holder element possible through the threaded ring.
