Abstract
Abstract An aerosol valve button featuring an aspirator passageway having one end in communication with the atmosphere and its other end adjacent the button''s discharge orifice. Product-flow through the discharge orifice causes an air-stream to flow in the aspirator passageway. This auxiliary air-stream reduces eddy currents and other turbulence at the discharge orifice; thus providing more efficient breakup and distribution of the sprayed aerosol product with less propellant.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
A valve button for an aerosol container comprising a productflow opening therethrough defined at one end by a port arranged for communication with an aerosol product and at the other end by a discharge orifice, said product-flow opening including a product-flow channel leading into a product-flow chamber, said chamber being closed at its rearward end and open at the front face of said valve button, said discharge orifice disposed in the opening of the product-flow chamber and an aspirator passageway formed in said valve button, one end of said aspirator passageway formed in communication with the atmosphere via an opening extending from the base of said valve button, the other end of said aspirator passageway arranged immediately behind said discharge orifice whereby product flowing from said discharge orifice causes an airstream to flow in said aspirator passageway.
Claim 2
Dependent Claim
137 words
A valve button for an aerosol container comprising a productflow opening therethrough defined at one end by a port arranged for communication with an aerosol product and at the other end by a discharge orifice, said product-flow opening including a product-flow channel leading into a product-flow chamber, said chamber being closed at its rearward end and open at the front face of said valve button, said discharge orifice disposed in the opening of the product-flow chamber and an aspirator passageway formed in said valve button, one end of said aspirator passageway formed in communication with the atmosphere via an opening extending from the base of said valve button, the other end of said aspirator passageway arranged immediately behind said discharge orifice whereby product flowing from said discharge orifice causes an airstream to flow in said aspirator passageway.
Claim 3
Dependent Claim
104 words
A valve button for an aerosol container comprising a product-flow opening therethrough defined at one end by a port arranged for communication with an aerosol product and at the other end by a discharge orifice, and an aspirator passageway formed in said valve button, one end of said aspirator passageway formed in communication with the atmosphere the other end of said aspirator passageway arranged adjacent to said discharge orifice whereby product flowing from said discharge orifice causes an airstream to flow in said aspirator passageway, said valve button including means to move said other end of said aspirator passageway relative to said discharge orifice.
Claim 4
Dependent Claim
104 words
A valve button for an aerosol container comprising a product-flow opening therethrough defined at one end by a port arranged for communication with an aerosol product and at the other end by a discharge orifice, and an aspirator passageway formed in said valve button, one end of said aspirator passageway formed in communication with the atmosphere the other end of said aspirator passageway arranged adjacent to said discharge orifice whereby product flowing from said discharge orifice causes an airstream to flow in said aspirator passageway, said valve button including means to move said other end of said aspirator passageway relative to said discharge orifice.
Claim 5
Dependent Claim
52 words
The valve button of claim 2 wherein said means is defined by a dial screw in which the aspirator passageway is disposed, and which is threadably engaged to the body of the button such that rotation of the screw moves the other end of the aspirator passageway relative to the discharge orifice.
Claim 6
Dependent Claim
148 words
A valve button for An aerosol container comprising a product-flow opening therethrough defined at one end by a port arranged for communication with an aerosol product and at the other end by a discharge orifice, and an aspirator passageway formed in said valve button, one end of said aspirator passageway formed in communication with the atmosphere, the other end of said aspirator passageway arranged adjacent to said discharge orifice whereby product flowing from said discharge orifice causes an airstream to flow in said aspirator passageway, said valve button including a dial disposed in said aspirator passageway, said dial having first and second elements with means to rotate the first element relative to the other, a plurality of bores extending through said first and second elements for passage of said airstream, and said bores being opened or closed by rotation of said first element relative to said second element.
Claim 7
Dependent Claim
148 words
A valve button for An aerosol container comprising a product-flow opening therethrough defined at one end by a port arranged for communication with an aerosol product and at the other end by a discharge orifice, and an aspirator passageway formed in said valve button, one end of said aspirator passageway formed in communication with the atmosphere, the other end of said aspirator passageway arranged adjacent to said discharge orifice whereby product flowing from said discharge orifice causes an airstream to flow in said aspirator passageway, said valve button including a dial disposed in said aspirator passageway, said dial having first and second elements with means to rotate the first element relative to the other, a plurality of bores extending through said first and second elements for passage of said airstream, and said bores being opened or closed by rotation of said first element relative to said second element.
Claim 8
Dependent Claim
25 words
The valve button of claim 1 wherein said discharge orifice is disposed in a removable insert positioned within the forward portion of said product-flow chamber.
Claim 9
Dependent Claim
33 words
The valve button of claim 3 wherein said dial screw is threadably engaged with the body of said button such that the rotation of said dial screw closes or opens said aspirator passageway.
