First Claim
1. A device for puncturing a pressurized container for relieving the pressure therein and for releasing the residual contents thereof into a drum of a type having an end wall with a surrounding protruding peripheral rim, said device comprising:
- a generally elongated housing member defining an elongated cavity with openings at first and second ends thereof for receiving a pressurized container at said first end and further including an attachment means for securing said second end of said housing member to said end wall of said drum for collection by said drum of contents expelled from said pressurized container through said second end;
a puncturing means mounted on said housing member intermediate said first and second ends for piercing said pressurized container in said elongated cavity whereby gases and residual contents thereof are emptied into said drum through said opening at said second end;
a counter means cooperatively engaged with said puncturing means wherein said counter means records each piercing of said pressurized container by an increasing count such that at a plurality of preselected counts prior to a preselected maximum count and without resetting the counter, at least one maintenance activity is indicated as due and such that at preselected additional increasing counts an additional maintenance activity is indicated as due;
said device further including an auxiliary support means for extending from said housing member to said protruding peripheral rim of said drum for stabilizing relative movement between said housing member and said drum during operation of said device.

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.

8. A device for puncturing a pressurized container for relieving the pressure therein and for releasing the gases and residual contents thereof into a collection receptacle, said device comprising:
-
a generally elongated housing member defining an elongated cavity with openings at first and second ends thereof for receiving a pressurized container at said first end and further including an attachment means for securing said second end of said housing member to said receptacle for collecting contents expelled from said pressurized container through said second end; a puncturing means mounted on said housing member intermediate said first and second ends for piercing said pressurized container whereby gases and residual contents thereof are emptied into said collection receptacle through said opening at said second end; a counter means cooperatively engaged with said puncturing means wherein said counter means records each piercing of said pressurized container by an increasing count such that at a plurality of preselected counts prior to a preselected maximum count and without resetting the counter, at least one maintenance activity is indicated as due and such that at preselected additional increasing counts an additional maintenance activity is indicated as due; said device further comprising a force-applying means movably mounted on said housing member for engaging said pressurized container positioned in said elongated cavity and forcing said pressurized container towards said second end, wherein said force-applying means comprises a plate affixed to a shaft which is slidably mounted on said housing member. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. In a device for puncturing a pressurized container for relieving the pressure therein and for releasing for collection in a receptacle, residual contents thereof, the improvement wherein:
-
said device comprises a generally elongated housing member defining an elongated cavity with openings at first and second ends thereof for receiving a pressurized container therein at said first end and further including an attachment means for selectively securing said second end of said housing member to a receptacle for collecting contents expelled from said second end and for supporting said housing; a puncturing means mounted on said housing member intermediate said first and second ends for piercing said pressurized container in said cavity whereby gases and residual contents thereof are emptied into said collection receptacle through said opening at said second end; a counter means cooperatively engaged with said puncturing means wherein said counter means records each piercing of said pressurized container by an increasing count such that at a plurality of preselected counts prior to a preselected maximum count and without resetting the counter, at least one maintenance activity is indicated as due and such that at preselected additional increasing counts an additional maintenance activity is indicated as due; and wherein said housing member defines an internal shoulder within said elongated cavity between said puncturing means and said first end whereby said pressurized container can be inserted into said first end in an inverted attitude with an external shoulder thereof engaging said internal shoulder, with a portion thereof extending below said shoulder means to be punctured by said puncturing means. - View Dependent Claims (16, 17, 18, 19, 20)
