[0022] Aerosol dispensers are commonly used to dispense personal, household, industrial, and medical products. Typically, aerosol dispensers include a container which holds a product to be dispensed. A propellant is used to discharge the product from the container. The propellant is pressurized inside the container and provides a force to expel the product from the container when a user actuates the aerosol dispenser by pressing an actuator or a trigger. Traditional aerosol dispensers utilize organic propellants that are high in volatile organic compounds or VOCs. This makes use of such aerosol dispensers subject to various VOC regulations.
[0023] The present disclosure provides an aerosol dispenser. The aerosol dispenser includes an outer container including a closed bottom end and an open neck longitudinally opposite to the closed bottom end. The aerosol dispenser further includes a valve sealed to the open neck in a fluid-tight manner. The aerosol dispenser further includes a product container disposed within the outer container and containing a product therein. The product container is fluidly coupled to the valve in a fluid-tight manner. The valve is configured to selectively dispense the product from the product container. The outer container defines therein a container volume that is outside of and at least partially surrounding the product container. The container volume contains a pressurized gas therein, such that the pressurized gas pressurizes the product within the product container to a pressure greater than an ambient pressure for selectively dispensing the product through the valve.

Specifically, the delivery orifice 126 is in fluid communication with the valve 112. Thus, the user may dispense the product 116 by actuating the actuator 124, which may subsequently actuate the valve 112 for dispensing the product 116 through the delivery orifice 126. In some embodiments, the valve 112 may be a check valve. In some embodiments, a flow rate 134 of the product 116 through the valve 112 is about 60 gram per minute (g / min) to 120 g / min.
[0033] FIG. 3 is a schematic cross-sectional view of the product package 100, according to an embodiment of the present disclosure. Referring to FIGS. 1-3, the aerosol dispenser 104 further includes a product container 114 disposed within the outer container 106 and containing the product 116 therein. Specifically, the product package 100 further includes the product 116 received in the product container 114. The product container 114 is fluidly coupled to the valve 112 in a fluid-tight manner. The valve 112 is configured to selectively dispense the product 116 from the product container 114.
[0034] In some embodiments, the product container 114 is a flexible bag. For example, the product container 114 includes a mylar bag. However, other types of flexible bags may also be utilized. The product 116 is an adhesive. Specifically, the adhesive is a water-based adhesive or any solvent based adhesive. In some embodiments, the adhesive includes an emulsion.
[0035] The outer container 106 defines therein a container volume 118 that is outside of and at least partially surrounding the product container 114. The product package 100 further includes a pressurized gas 120 received within the container volume 118. Specifically, the container volume 118 contains the pressurized gas 120 therein, such that the pressurized gas 120 pressurizes the product 116 within the product container 114 to a pressure Pl (shown in FIG. 3) greater than an ambient pressure P2 (shown in FIG. 3) for selectively dispensing the product 116 through the valve 112. Specifically, the pressurized gas 120 physically squeezes the product container 114 to pressurize the product 116 within the product container 114 to the pressure Pl greater than the ambient pressure P2, thereby forcing the product 116 within the product container 114 to be expelled through the valve 112 disposed at the uppermost part of the aerosol dispenser 104 when the user actuates the actuator 124.
[0036] In some embodiments, the pressurized gas 120 is compressed air or nitrogen gas or an inert gas. In some other embodiments, the pressurized gas 120 may be any other gas or a mixture of gases. Thus, the product package 100 or the aerosol dispenser 104 does not utilize propellants containing harmful volatile organic compounds or VOCs for dispending the product 116. The only VOCs present in the product package 100 or the aerosol dispenser 104 are contained within the product 116 itself (i.e., the adhesive).
[0037] FIG. 4 is a flowchart illustrating a method 200 of dispensing the product 116 (shown in
[0038] FIGS. I and 3). The method 200 may be implemented using the product package 100 or the aerosol dispenser 104 shown in FIGS. 1-3.

The product container 114 is fluidly coupled to the valve 112 in a fluid-tight manner. The product 116 is an adhesive.
[0039] In some embodiment, the product container 114 is a flexible bag. In some embodiments, the adhesive is a water-based adhesive. In some embodiments, the adhesive includes an emulsion.
[0040] At step 204, the method 200 further includes actuating the actuator 124 operatively coupled to the valve 112. The actuator 124 includes the delivery orifice 126 that in fluid communication with the valve 112. In some embodiments, the delivery orifice 126 has the orifice diameter 128 of about 0.010 inches to 0.025 inches.
[0041] At step 206, the method 200 further includes dispensing the product 116 through the delivery orifice 126 upon actuation of the actuator 124. In some embodiments, the flow rate 134 of the product 116 through the valve 112 is about 60 g / min to 120 g / min. In some embodiments, dispensing the product 116 through the delivery orifice 126 further includes spraying the product 116 in the fan spray pattern 130 or the cone spray pattern 130 with the spray angle 132 of about 40° to 60°.
[0042] Referring to FIGS. 1-4, the aerosol dispenser 104 of the present disclosure includes the product container 114 disposed within the outer container 106 and containing the product 116 therein. The outer container 106 defines therein the container volume 118 that is outside of and at least partially surrounding the product container 114. The container volume 118 contains the pressurized gas 120 (e.g., compressed air or nitrogen gas) that pressurizes the product 116 within the product container 114, thereby allowing the product 116 to be selectively dispensed through the valve 112. Thus, the aerosol dispenser 104 of the present disclosure allows dispensing of the product 116 without using any propellant. This may eliminate any use of propellants containing volatile organic compounds or VOCs.
