A nozzle insert, and/or an actuator nozzle structure, for use in dispensing a material to be dispensed from an aerosol can. The nozzle insert or actuator nozzle structure divide the spray of dispensed material into two independent, simultaneously emitted aerosol streams, which may have different attributes and may be emitted in different directions. One stream may be an upwardly directed fogger stream and the other stream may be a forwardly directed, aimable stream. This permits a user to direct, for example, an insecticide at a particular target, while simultaneously more generally fogging an area of interest.

A single nozzle insert member for an aerosol dispenser containing pressurized material to be dispensed, the insert member comprising:an elongated body having an inlet end suitable to be mounted at an exit of an actuator for the aerosol dispenser, an outlet end, a conduit there between, and a cap at the outlet end;the cap having two separate outlets in communication with the conduit, the two outlets so configured as to impart differing flow characteristics to the stream of material dispersed therefrom;whereby when material to be dispensed from the aerosol dispenser is delivered to the conduit, the nozzle insert will simultaneously project a first spray having a first flow characteristic from one of the separate outlets and a second spray having a second flow characteristic and that is independent from the first spray at the time of exit from the other of the separate outlets;wherein the two outlets have different cross sectional profiles from each other; andwherein a first outlet comprises an elongated slot that widens in a downstream direction. 4. The single nozzle insert member of claim 3, wherein the elongated slot extends both radially and axially with respect to a longitudinal axis of the nozzle insert. 5. The single nozzle insert member of claim 2, wherein a first outlet comprises a circular outlet hole. 6. A single nozzle insert member for an aerosol dispenser containing pressurized material to be dispensed, the insert member comprising:an elongated body having an inlet end suitable to be mounted at an exit of an actuator for the aerosol dispenser, an outlet end, a conduit there between, and a cap at the outlet end;the cap having two separate outlets in communication with the conduit, the two outlets so configured as to impart differing flow characteristics to the stream of material dispersed therefrom;whereby when material to be dispensed from the aerosol dispenser is delivered to the conduit, the nozzle insert will simultaneously project a first spray having a first flow characteristic from one of the separate outlets and a second spray having a second flow characteristic and that i s independent from the first spray at the time of exit from the other of the separate outlets;wherein the two outlets have different cross sectional profiles from each other;wherein a first outlet comprises a circular outlet hole; andwherein the circular outlet hole extends axially with respect to a longitudinal axis of the nozzle insert. 7. A single nozzle insert member for an aerosol dispenser containing pressurized material to be dispensed, the insert member comprising:an elongated body having an inlet end suitable to be mounted at an exit of an actuator for the aerosol dispenser, an outlet end, a conduit there between, and a cap at the outlet end;the cap having two separate outlets in communication with the conduit, the two outlets so configured as to impart differing flow characteristics to the stream of material dispersed therefrom;whereby when material to be dispensed from the aerosol dispenser is delivered to the conduit, the nozzle insert will simultaneously project a first spray having a first flow characteristic from one of the separate outlets and a second spray having a second flow characteristic and that is independent from the first spray at the time of exit from the other of the separate outlets;wherein the two outlets have different cross sectional profiles from each other; andwherein the outlets are at least partially directed in radial opposition to each other. 8. A single nozzle insert member for an aerosol dispenser containing pressurized material to be dispensed, the insert member comprising:an elongated body having an inlet end suitable to be mounted in an exit of an actuator for the aerosol dispenser, an outlet end, a conduit there between, and a cap at the outlet end;the cap having two separate outlets in communication with the conduit, the two outlets so configured as to impart differing flow characteristics to the stream of material dispersed therefrom;whereby when material to be dispensed from the aerosol dispenser is delivered to the conduit, the nozzle insert will simultaneously project a first spray having a first flow characteristic from one of the separate outlets and a second spray having a second flow characteristic and that is independent from the first spray at the time of exit from the other of the separate outlets;wherein the insert is a unitary housing made of a flexible material. 9. A single nozzle insert member for an aerosol dispenser containing pressurized material to be dispensed, the insert member comprising:an elongated body having an inlet end suitable to be mounted at an exit of an actuator for the aerosol dispenser, an outlet end, a conduit there between, and a cap at the outlet end;the cap having two separate outlets in communication with the conduit, the two outlets so configured as to impart differing flow characteristics to the stream of material dispersed therefrom;whereby when material to be dispensed from the aerosol dispenser is delivered to the conduit, the nozzle insert will simultaneously project a first spray having a first flow characteristic from one of the separate outlets and a second spray having a second flow characteristic and that is independent from the first spray at the time of exit from the other of the separate outlets;wherein the insert is generally cylindrical, with a first upstream section of a first diameter, a collar section downstream of the first upstream section and having a diameter larger than the first diameter, and a cap section downstream of the collar section having a diameter larger than the diameter of the collar section. 10. An actuator for an aerosol dispenser, comprising:a receiver and a through conduit in fluid communication with an actuator outlet, the receiver being connectible to a valve stem that extends from the dispenser, the receiver having a recess for receiving the stem and the through conduit being sized to pass material to be dispensed and contained in the aerosol dispenser to that actuator outlet; anda nozzle integrally f ormed with the actuator and positioned at that actuator outlet, the nozzle having two separate outlets in communication with the through conduit, the two outlets being so configured as to impart differing flow characteristics to the stream of material dispensed therefrom;whereby, when material to be dispensed from the aerosol dispenser is delivered to that through conduit, the nozzle simultaneously projects a first spray having a first flow characteristic from one of the separate outlets and a second spray having a second flow characteristic from the other of the separate outlets;wherein the actuator is in the form of a push button. 11. The actuator of claim 10, wherein the actuator is part of an overcap. 12. A method of delivering a sprayable material to be dispensed from an aerosol container to an ambient environment, the method comprising the steps of:(a) providing an aerosol container containing a sprayable material to be dispensed, the container having an exit valve;(b) actuating the exit valve to deliver a stream of the material to be dispensed from the container, and then dividing the stream into two independent streams at an outlet nozzle; and(c) emitting the two independent streams from a single outlet cap of the nozzle into the ambient environment, the two streams differing from each other in flow characteristics;wherein at least one such stream is emitted into the ambient environment in an upward direction when a longitudinal axis of the can is held vertical. 13. The method of claim 12, wherein at least one such stream is emitted into the ambient environment directed essentially horizontally when the aforesaid axis of the can is held vertical. 14.
