Abstract
A filling head gun assembly has a housing; a handle assembly connected to the housing; a filling head attached to the housing; and a plunger. The plunger extends through an opening of the housing and an activator reservoir attached to the plunger. The reservoir is moved into position to contact the filling head via the plunger to feed pressurized activator through the filling head to an aerosol can. A cover is releasably attached to an end of the filling head which provides a seal around the filling head.
Claims16
A filling head gun assembly comprising:
- a housing;
- a pressurized activator;
- a reservoir for containing said activator;
- a handle assembly connected to said housing;
- a filling head attached to said housing;
- and a plunger, wherein said plunger extends through an opening of said housing and said activator reservoir attached to said plunger, said reservoir is moved into position to contact said filling head via said plunger to feed pressurized activator through said filling head to an associated aerosol can and a protective cover releasably attached to an end of said filling head which provides a seal around said filling head;
- and
- wherein said filling head comprises a stem to seal an associated valve mounting cap of said aerosol can and forms a single releasable non-threaded connection to said aerosol can;
- wherein said protective cover comprises an upper wall having an opening therethrough for said filling head and a side wall depending downwardly from said upper wall forming an inner cavity which substantially surrounds and covers at least a portion of an end portion of said filling head and said associated aerosol can.
