Device for the extraction of cartridges

A device for extracting material contained in a cartridge comprising:

• a housing body having a substantially cylindrical hollow interior extending to and terminating at an open bottom of the housing body, the hollow interior being defined by the inside of the housing body and substantially conforming with an outer form of a cartridge containing material to be extracted, for accepting the cartridge for extraction and having an upper portion including a injection element having a point protruding into the hollow interior of the housing body along a central longitudinal axis of the interior of the housing body for opening and penetrating the cartridge for extraction;
• at least one hole in the injection element communicating with a bore through the upper portion of the housing body for receiving water and for providing water to the cartridge for extraction;
• an upper part protruding from the upper portion of the housing body outside of the housing body;
• a lower stop, beneath and displaced from the upper protruding part, on a lower portion of the housing body protruding from the outside of the housing body;
• a movable ring circumscribing the housing body and the stop and having a lug protruding towards the outside of the housing body at a position above the stop capable of communicating with the stop, the lug being at a position on the ring such that when the lug and stop are in communication, the ring protrudes below the bottom of the housing body;
• and
• a spring confined between the lug and the upper protruding part and the ring and the housing body for urging the lug into communication with the stop.
