Actuator for an aerosol container
First Claim
1. An actuator for an aerosol container, comprising:
- a body (12) formingi) an inlet (14) to connect the actuator (10) to a discharge outlet of the container, in fluid communication therewith, to receive fluid therefrom,ii) a top surface (16) defining a multitude of elongated discharge slits (20) to discharge fluid from the actuator, andiii) a multitude of body passageways (22) extending between the inlet and a respective one of the discharge slits to conduct the fluid from the inlet to said one of the discharge slits,the body passageways each being formed in an upper massive part of the body and each having a narrow upper portion (22a), a narrow lower portion (22b) and a wider mid portion (22c), to allow the fluid to expand as the fluid is conducted outward through the body passageways and to draw back into the body passageways excess fluid from the top surface of the actuator.

Abstract
An actuator for an aerosol container, comprising a body forming an inlet, a top surface (16) defining a multitude of discharge slits (20), and a multitude of body passageways (22) to conduct fluid from the inlet to the discharge slits. Each of the body passageways has a pouch shape, including narrower upper (22a) and lower portions (22b) and a wider mid portion (22c). When the actuator is used to dispense foam from an aerosol container, the shape of the body passageways has several advantages. First, that shape helps the foam to expand as it passes outward through the dispenser, and second, after the container has been used to dispense a quantity of foam, the shape of the body passageways helps to draw back into the actuator any excess foam remaining on the outside of the actuator. Preferably, the actuator is formed in a plastic injection molding process, and the body passageways of the actuator are formed into the desired shape as the plastic cools during the molding process.
