  • Patent number: 5413230
    Abstract: A refillable compressed gas capsule, in particular, for household uses and for compressed-gas hand-operated devices, includes a valve body pretensioned by a spring and slidably held against a valve seat by the inner pressure of the compressed-gas capsule and against the pretension towards the interior of the capsule, which body is held in a holding means inserted into an opening provided in the face side of the capsule limiting the opening path of said valve body and comprising at least one opening leading into the interior of the capsule. In order to produce such a compressed-gas capsule in a very simple manner, it is provided that the holding means and the valve seat are held at least indirectly by an inwardly directed flanged edge of the capsule.
