Abstract
A puncturing device for pressurized containers comprises an elongated housing defining an elongated cavity with openings at either end for receiving an inverted pressurized container at one end, the housing including a selective attachment member for securing the other end of the housing to a collection receptacle. A non-sparking puncturing apparatus, with a lever having a built-in stop, is movably mounted on the housing with a pivot-link-driven puncture pin extending through an intermediate aperture into the cavity for piercing a nozzle-end of the pressurized container below an internal shoulder thereof with a seal. A counter records each action of the puncture pin. Container contents are released into the receptacle. An auxiliary support is rotatably mounted on the housing for stabilizing relative movement between the housing and the receptacle. A force-applying apparatus is mounted on the housing for engaging the pressurized container and holding it on the seal.
