Insert for dispensing a compressed gas product, system with such an insert, and method of dispensing a compressed gas product

Abstract

An insert, a system, and a method for dispensing a compressed gas product. The insert includes a swirl chamber, inlet ports to the swirl chamber, and an outlet orifice. The insert has specifically configured parameters relating to the diameter of the swirl chamber, the diameter of the outlet orifice, the length of the outlet orifice, and the depth of the swirl chamber. The insert, system, and method can provide a dispensed compressed gas product with a remarkably constant flow rate and with a remarkably constant particle size.

1 . A method of dispensing a compressed gas product from a container and dispensing assembly that includes an insert with a swirl chamber, the method comprising:
 providing a product in the container such that the pressure inside the container is less than about 157 psi at 70° F.;   dispensing the product from the container through the insert such that the flow rate of product out of the insert when the container is about 13% full of product is at least about 65% that of the initial flow rate of product out of the insert when the container is 100% full of product.   
     
     
         2 . A method according to  claim 1 , wherein a flow rate of product during an initial sixty second dispensing from the container is at least about 1.7 g/sec. 
     
     
         3 . A method according to  claim 2 , wherein an average particle size during the sixty second dispensing is about 65 μm. 
     
     
         4 . A method according to  claim 1 , wherein a flow rate of product when the container is about 13% full of product is about 1.3 g/s. 
     
     
         5 . A method according to  claim 4 , wherein an average particle size when the container is about 13% full of product is about 85 μm. 
     
     
         6 . A method according to  claim 1 , wherein the pressure inside the container prior to any dispensing of the product is about 135 psig. 
     
     
         7 . A method according to  claim 6 , wherein the compressed gas product includes an air freshening compound. 
     
     
         8 - 14 . (canceled) 
     
     
         15 . A system for dispensing a compressed gas product, the system comprising:
 a container for containing a volume of compressed gas product; and   a compressed gas product inside the container, the compressed gas product including a gas component and a liquid component,   wherein the compressed gas product dispensed from the container has a flow rate of (i) at least about 2.0 g/s during an initial ten second dispensing period from the container, and (ii) at least about 1.3 g/s during a ten second dispensing period when the container has about 13% of the initial amount of compressed gas product remaining in the container.   
     
     
         16 . A system according to  claim 15 , wherein about 230 grams of the compressed gas product are initially provided in the container. 
     
     
         17 . A system according to  claim 15 , wherein an initial pressure of the container is about 135 psig. 
     
     
         18 . A system according to  claim 15 , wherein the liquid component of the compressed gas product includes an air freshener. 
     
     
         19 . A system for dispensing a compressed gas product, the system comprising:
 a container for containing a volume of compressed gas product; and   a compressed gas product inside the container, the compressed gas product including a gas component and a liquid component,   wherein the compressed gas product dispensed from the container has a flow rate of (i) at least about 2.0 g/s during an initial ten second dispensing period from the container, (ii) at least about 1.7 g/s during a ten second dispensing period when the container has about 66% of the initial amount of compressed product remaining, (iii) at least about 1.4 g/s during a ten second dispensing period when the container has about 33% of the initial amount of compressed product remaining, and (iv) at least about 1.3 g/s during a ten second dispensing period when the container has about 13% of the initial amount of the compressed gas product remaining.   
     
     
         20 . A system according to  claim 19 , wherein about 230 grams of compressed gas product are initially provided in the container. 
     
     
         21 . A system according to  claim 19 , wherein an initial pressure of the container is about 135 psig. 
     
     
         22 . A system according to  claim 19 , wherein the liquid component of the compressed gas product includes an air freshener. 
     
     
         23 . A system for dispensing a compressed gas product, the system comprising:
 a container; and   a compressed gas product provided inside the container, the compressed gas product including a gas component and a liquid component,   wherein the system is configured to dispense the compressed gas product such that a flow rate of compressed gas product when the system is about 13% full of product is at least about 65% that of an initial flow rate of product when the system is 100% full of product, and   wherein the system is configured to dispense the compressed gas product such that the particle size increases by less than about 40% as the amount of product in the container drops to 13% of the initial amount of product in the container.   
     
     
         24 . A system according to  claim 23 , wherein the compressed gas product dispensed from the container has a flow rate of about 1.85 g/s during an initial sixty second dispensing from the container, and
 wherein an average particle size dispensed from the container during the sixty seconds of dispensing is about 65 μm.   
     
     
         25 . A method of maintaining a spray rate of compressed gas product, the method comprising:
 providing the compressed gas product inside a container such that the pressure inside the container is less than about 157 psi; and   dispensing the compressed gas product from the container,   wherein the compressed gas product has a flow rate of at least about 1.7 g/s during an initial sixty second dispensing from the container, and   wherein the spray rate decreases by less than about 0.7 g/s as the compressed gas product is discharged from a full container to a point when the container has about 13% of the compressed gas product remaining.
