Abstract
A device for both instant and continuous dispensing of an air-treating composition. The device has a pressurized vessel with a valve stem, an actuator-overcap, and an absorbent member adjacent to vented actuator-overcap walls. The actuator-overcap, which is preferably a single integrally-molded piece, has an actuator button and a channel member engaged with the stem and terminating in a spray orifice. The channel member and/or the valve stem have outlets for directing liquid onto the absorbent member, and the spray orifice, outlets and liquid passageway are configured such that the rate of discharge onto the absorbent member exceeds the rate of spray discharge into the air, preferably by more than 2:1.
Claims20
A device for both instant and continuous dispensing of air-treating composition comprising:
- a pressurized vessel containing air-treating liquid and having a protruding depressible valve stem;
- an actuator-overcap attached to the vessel and including a vented wall, an actuator button, and channel means secured to the button and having a first end engaged with the stem and a second end terminating in a spray orifice directed outside the actuator-overcap, said channel means and stem forming a passageway for fluid exiting the vessel;
- an absorbent member within the actuator-overcap between the passageway and the vented wall;
- and outlet means in said passageway for directing the liquid onto the absorbent member during spraying through the spray orifice, the outlet means, passageway and spray orifice being configured such that the rate of discharge through the outlet means exceeds the rate of discharge through the spray orifice,
- wherein the outlet means, passageway and spray orifice are configured such that the ratio of the rate of discharge through the outlet means to the rate of discharge through the spray orifice is at least 2:1.
