BACKGROUND

1. Field of the Disclosure

The present disclosure is directed to a spray delivery system for an actuator used in an aerosol product dispenser. More particularly, the present disclosure relates such a spray delivery system for a high viscous product that minimizes pressure loss and enhances mechanical breakup of product.

2. Description of Related Art

Aerosol systems dispense a variety of products from a container. In traditional aerosol dispensers, the product to be dispensed is mixed in a solvent and a propellant. In bag on valve (BOV) dispensers, product to be dispensed and propellant are separated by a bag welded to the valve. In both types, product is stored at a pressure in the container and dispensed via a nozzle upon actuation of a valve. Accordingly, the product to be dispensed can exist in in one or more (gas, liquid) phases or partial phases and in an emulsified state.

Product is dispensed as a plurality of atomized drops or particles of a fluid. Over time, pressure in the can reduces, in part due to a volume increase resulting from product being dispensed, also referred to a pressure loss from expansion. In part, some gas is inevitably released together with the product.

It is desirable that the atomized drops have or form a uniform pattern in the direction of flow. For example, the atomized drops can be in a flat, cone, or fan-like pattern.

There exists a problem with current aerosol systems when the product to be dispensed has a high viscosity.

First, pattern uniformity decreases as the container empties, rendering the portion of product dispensed properly to be significantly less than the total amount of product in the container.

Second, pattern uniformity decreases while pressure loss increases as product viscosity increases.

Moreover, the problem is further compounded because product viscosity is a function of environmental variables like temperature that are not always controllable.

SUMMARY

The present disclosure provides a spray delivery system that enables a high viscosity product to be dispensed from a container in a uniform pattern of atomized drops.

The present disclosure also provides that the spray delivery system facilitates mechanical breakup of high viscous product.

The present disclosure further provides a spray delivery system with a dual channel geometry that feeds a spray nozzle with minimal pressure drop.

The present disclosure yet further provides that the spray delivery system atomizes high viscous product into a uniform flat, cone, or fan-like pattern.

The present disclosure still further provides a spray delivery system that reduces pressure loss in a container and atomizes high viscous product into a uniform flat, cone, or fan-like pattern throughout a lifespan of the container.

The present disclosure also provides a method of dispensing a high viscosity product from a container.
