Abstract
A continuous dispensing actuator assembly having a mounting cup, an actuator, an overcap and a locking adaptor provides for automatic discharge of the contents of a pressurized container. The mounting cup secures to an open end of the pressurized container and has a valve biased into a normally extended closed position with an extending valve stem. The overcap includes a base portion affixed to the mounting cup, an orientation tab slidably residing within the slot in the actuator to prevent rotational movement of the actuator, a locking mechanism and a slot in the locking mechanism sized to allow passage of the actuator cam post.
Claims17
A continuous dispensing actuator assembly for a pressurized container comprising:
- an actuator having a stem seat adapted to receive a valve stem of a valve, a discharge outlet in fluid communication with the stem seat and a cam post;
- an overcap having a base portion for engagement with a mounting cup of the pressurized container on a lower surface and a lock mechanism cooperating with the overcap;
- the lock mechanism having a cam surface adapted to engage the cam post to cause axial reciprocation of the actuator between an open continuous spray position and a closed position.
A pressurized container including a continuous dispensing actuator assembly comprising:
- an actuator having a stem seat for receiving a valve stem of a valve, a discharge outlet in fluid communication with the stem seat, a cam post and rotational control means for maintaining the actuator in a rotationally fixed position relative to the valve stem;
- an overcap having an opening sized to allow passage of the actuator at least partially through the overcap;
- and
- wherein a lock mechanism is provided with the overcap and includes a cam surface to engage the actuator cam post to influence the actuator in an axial manner relative to the valve stem.
A continuous dispensing actuator assembly for a pressurized container comprising:
- an actuator having a stem seat for receiving a valve stem of a valve, a discharge outlet in fluid communication with the stem seat, a cam post and control means for maintaining the actuator in a fixed position relative to the valve stem;
- an overcap having a radial passage to allow passage of a lock button at least partially through the overcap and a spring tab biasing the lock button in a closed position, the lock button having an aperture with a cam surface to allow passage of the actuator at least partially through the lock button;
- and
- wherein the cam surface of the lock button is adapted to engage the actuator cam post to reciprocate the actuator in an axial manner relative to the valve stem.
A method of dispensing pressurized fluids from a pressurized container comprising the steps of:
- providing an actuator having a stem seat adapted to receive a valve stem of a valve, a discharge outlet in fluid communication with the stem seat and a cam post;
- forming an overcap having a base portion for engagement with a mounting cup of the pressurized container on a lower surface and a passage for accepting a lock button;
- inserting the lock button through the passage in the overcap, the lock button having an aperture and a cam surface;
- inserting the actuator through the aperture of the lock button;
- and
- actuating the lock button to engage the cam post to cause axial reciprocation of the actuator to an open continuous spray position.
