Abstract
Abstract A spray nozzle is disclosed for a fluid dispenser, consisting of a button mounted on the end of a product discharge tube or valve stem of the dispenser. The button has a discharge orifice through which the fluid product is sprayed, and the button and stem are formed in their mating surfaces to provide a variable restriction to discharge of fluid from the orifice in different relative rotated positions of the button on the stem.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
196 words
A spray nozzle for a fluid dispenser, comprising a tubular stem forming a duct for flow of fluid product therethrough and a button member mounted on an end of said stem closing said end; said button member having a socket opening onto one of its faces within which said stem is received in the mounted position, said socket being closed at its distal end, and a discharge passage leading through the wall of said button to communicate with said socket adjacent said distal end; a narrow circumferentially extending recess of varying depth along its arcuate extent located in the wall of said socket and positioned to intersect the inner end of said discharge orifice; said tubular stem having an aperture formed in its sidewall, all portions of said aperture being confined within said socket when said button is mounted on said stem; said socket wall and the outer surface of said tubular stem forming a fluidtight but relatively rotatable seal at their respectively abutting areas when said stem is received in said socket in the mounted position of said button, said abutting areas including one portion that is peripherally continuous axially outwardly of said stem aperture.
Claim 2
Dependent Claim
196 words
A spray nozzle for a fluid dispenser, comprising a tubular stem forming a duct for flow of fluid product therethrough and a button member mounted on an end of said stem closing said end; said button member having a socket opening onto one of its faces within which said stem is received in the mounted position, said socket being closed at its distal end, and a discharge passage leading through the wall of said button to communicate with said socket adjacent said distal end; a narrow circumferentially extending recess of varying depth along its arcuate extent located in the wall of said socket and positioned to intersect the inner end of said discharge orifice; said tubular stem having an aperture formed in its sidewall, all portions of said aperture being confined within said socket when said button is mounted on said stem; said socket wall and the outer surface of said tubular stem forming a fluidtight but relatively rotatable seal at their respectively abutting areas when said stem is received in said socket in the mounted position of said button, said abutting areas including one portion that is peripherally continuous axially outwardly of said stem aperture.
Claim 3
Dependent Claim
25 words
A spray nozzle as defined in claim 1, wherein said aperture in said stem is formed by a notch in the end of the stem.
Claim 4
Dependent Claim
55 words
A spray nozzle as defined in claim 2, wherein said button member includes a lug projecting radially inwardly from the wall of said socket, said lug being received in said stem aperture in the mounted position of said button on said stem, said lug limiting the rotational positioning of said button relative to said stem.
Claim 5
Dependent Claim
27 words
A spray nozzle as defined in claim 1, wherein said recess in said socket wall tapers along its arcuate extent from a maximum depth to zero depth.
Claim 6
Dependent Claim
109 words
A spray nozzle as defined in claim 4, wherein said button member includes a lug projecting radially inwardly from the wall of said socket, said lug being received in said stem aperture in the mounted position of said button on said stem, said lug determining first and second limiting rotated positions of said button relative to said stem, said button when rotated to said first limiting position effecting maximum exposure of said arcuate recess to communication with said stem aperture, while relative rotated positions of said button and stem away from said first limiting position produce progressively reduced exposure of said arcuate recess to communication with said stem aperture.
Claim 7
Dependent Claim
30 words
A spray nozzle as defined in claim 5, wherein there is no exposure of said arcuate recess to said stem aperture in said second limiting rotated position of said button.
Claim 8
Dependent Claim
37 words
A spray nozzle as defined in claim 1, wherein one of said button and stem members has a radially projecting lug and the other has a recess for receiving said lug on its respectively adjacent sealing surface.
Claim 9
Dependent Claim
28 words
A spray nozzle as defined in claim 7, wherein said projecting lug is on said stem and said recess is formed in the wall of said button socket.
