Aerosol Freeze Formulation and Delivery System

Abstract

An environmentally safer aerosol freeze spray formulation and delivery system that is under pressure in an aerosol can and can only be released by pulling the trigger of the trigger sprayer by a finger or fingers. The trigger sprayer unit cannot be sprayed until the tab is pulled. The can is cylindrical canister housing and has a dip tube that goes into the can into the freeze spray. The freeze spray formulation in the can travels up through the dip tube up to the trigger sprayer and out a nozzle in which is cold and will flow out as an mist when the trigger is depressed.

DETAILED DESCRIPTION

[0013] Referring now to FIG. 1, a preferred embodiment of the invention is a can 1 that is strong enough to withhold aerosol can pressure. The can 1 has a can hole 2 at the top of the can. A mounting cup 3 at the top of the can is configured to fit on top of can 1 into the can hole 2. The mounting cup 3 has a actuator stem 4 which is attached to it and a dip tube 5 extends from the stem through the mounting cup into the can 1. The can 1 is filled partially with a freeze spray formulation 7 inside the can 1. The can 1 also has the freeze spray formulation in a gaseous state 6.

[0014] Referring now to FIG. 2 a preferred embodiment of the invention shows the bottom of a trigger spraying unit 8 in a preferred embodiment of the invention. The trigger sprayer unit 8 has a rim 9 configured to snap onto the mounting cup 3. The trigger sprayer unit also has one or more fitting units 10 that are configured to support and to grasp onto the mounting cup 3. The trigger sprayer unit 8 has a chamber hole 11 which secures over the actuator stem 4. The chamber hole 11 leads into a direction chamber 12 and is attached to the back of the trigger sprayer unit 8. A trigger 15 is able to pivot at a slight angle horizontally that allows it to pivot up and down. The trigger 15 uses a trigger pivoting member 16 to pivot up and down and is held in place by a trigger pivoting member holder 13.

[0015] Referring now to FIG. 3 a preferred embodiment of the invention shows a perspective side view of the trigger sprayer unit 8. A tab 17 is fitted on top of the trigger sprayer unit 8 which is attached to the trigger 15 in a preferred embodiment of the invention. The tab 17 must be removed for the trigger 15 to move and therein being able to move the nozzle 14. Referring now to FIG. 4 a cross sectional view of the trigger sprayer unit 8. The chamber hole 11 is at the bottom and the rim 9 can be seen that fits over the mounting cup 3. A trigger 15 fits inside the trigger sprayer unit 8. The chamber hole 11 goes into a direction chamber 12 which is hollow and allows the freeze spray formulation 7 to flow through. The freeze spray formulation 7 flows through the chamber hole 11 into direction chamber 12 out a nozzle 14. The trigger 15 pivots up and down by being pressed and by way of its trigger pivoting member 16. The trigger 15 has a nozzle holder 25 that holds onto the nozzle 14.

[0016] Referring now to FIG. 5 which shows a perspective side view of a aerosol freeze sprayer with trigger. A aerosol freeze sprayer with trigger whole unit 18 is shown as the whole invention. In this perspective view the can 1 is shown filled with freeze spray formulation 7. The upper portion of the can is filled with the gaseous freeze spray formulation 6 and the dip tube 5 goes down to the liquid freeze spray formulation 7. A mounting cup 3 holds the pressure inside the can 1. The trigger sprayer unit 8 fits onto the actuator stem 4 onto the mounting cup 3. The direction chamber as it fits on the actuator stem 4 is shown. The tab 17 as it fits on top of the trigger sprayer unit 8 and the nozzle 14 wherein the freeze spray formulation 7 flows out. The trigger pivoting 16 can be seen in Referring now to FIG. 6 shows a view of the trigger sprayer looking from above. The tab 17 is shown as it sits on top of the trigger sprayer unit 8. In this perspective view the tab has breakaway hinges 30 that allows the tab 17 to be pulled off. When the tab 17 is pulled off the nozzle 14 and direction chamber 12 are free to move up and down as the trigger 15 is pressed.
