Aerosol Freeze Formulation and Delivery System
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.

BACKGROUNDFreeze spray is used for medical use for freezing medical biopsies samples from humans or animals, freezing orthodontic archwires for bending and for electronics for testing circuit boards. The current freeze spray formulations are not very environmentally safe. This aerosol sprayer utilizes an environmentally safe formulation for freeze spray. Additionally the trigger sprayer allows the freeze spray to be used in a easy to use way. The trigger sprayer allows the user to be able to pull the tab so the formulation can be sprayed easily. When the tab is not pulled the aerosol freeze cannot be sprayed. Additionally this invention can easily be held in one hand for ease of use and portability.
SUMMARY OF THE INVENTIONThe invention is an aerosol freeze spray formulation and delivery system. In a preferred embodiment of the invention the trigger sprayer is fitted onto a mounting cup with a dip tube going to the bottom of the aerosol can to the freeze spray formulation. The direction chamber allows the freeze spray to flow through the trigger sprayer to the nozzle where it will flow out toward the area to be sprayed with the freeze spray formulation. The trigger when depressed puts pressure on the direction chamber that puts pressure on the actuator stem allowing the freeze spray to flow up then out. The nozzle on the trigger sprayer can is configured to allow the freeze spray to flow out rapidly. The freeze spray is in a gaseous form inside the can as well as a liquid form due to pressures of an aerosol can. A mounting cup is placed in the hole at the top of the aerosol can and holds the pressure of the freeze spray formulation. The mounting cup of the aerosol can has a actuator stem that when it is depressed cause the freeze spray formulation to flow out. The aerosol can is cylindrical. The trigger sprayer of the freeze spray has a tab on top of it that can be easily be pulled off which allows the trigger to be depressed and ready to be used. When this tab is not pulled the freeze spray cannot be sprayed for easy storage. The tab has breakaway hinges and can be snapped off easily. The trigger can be depressed by an index finger or other fingers to release the freeze spray formulation. The trigger sprayer has a nozzle wherein the freeze spray can flow out.
Operation of the InventionWhen the tab is not pulled the trigger of the freeze spray is locked and cannot be sprayed. The operation of the freeze spray is when there is a needed use, the user simply pulls the tab of the trigger sprayer which is located on top and this enables the trigger assembly to be pushed down on the mounting cup that has a stem sticking up that when depressed allows the propellant in the can to push the freeze spray up through the stem through the trigger sprayer unit through the direction chamber then through the nozzle toward the area to be sprayed. The freeze spray comes out with pressure and because the trigger has a nozzle the user can easily identify the direction to spray the freeze spray.
