Abstract
An apparatus for charging pressurized aerosol cans with liquid is provided having a reservoir, filler coupling and safety release device. The safety release device automatically prevents over-charging the can by interacting with the safety dome to cause the can to disengage from the filling reservoir.
Claims4
A system for safely filling a container with a paint formulation comprising, in combination,
- e. a container with a domed top and a safety indent;
- f. a housing;
- g. a reservoir operatively located within the housing;
- h. a piston and shaft operatively and removably associated with the reservoir;
- i. a handle operatively connected to the shaft;
- j. a filler coupling connected to the reservoir and in fluid communication with the container;
- and
- k. a safety release connected to the housing and engaging the domed top whereby a spatial change in the safety indent will cause the container to disengage from the safety release and the filler coupling.

A filling device for safely injecting paint formulations into a pressurized container comprising, in combination,
- a. a housing
- b. a reservoir operatively located within the housing;
- c. a piston and shaft operatively and removably associated with the reservoir;
- d. a handle operatively connected to the shaft;
- e. a filler coupling connected to the reservoir;
- and
- f. a safety release connected to the housing, wherein the safety release is adapted to releasably receive and connect to a partially filled and pre-pressurized container and to automatically release the container from the safety release in an over pressure condition,
- where the piston, handle, shaft and reservoir are configured to allow a user to hold the system in hand while injecting a paint formulation into the container under pressure.
