Abstract
Abstract An aerosol dispenser comprising a sealed container containing a plurality of compartments, each possessing a different dispensable material. A dip tube positioned in the container having radial inlet openings extending through it. Rotation of the dip tube about its axis aligns the inlet openings with ports which communicate with the compartments so a selected combination of materials can be dispensed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
98 words
An aerosol dispenser, comprising: a. a container having a plurality of compartments therein, b. each of said compartments adapted to contain a dispensable material, c. nozzle means on said container, d. valve means in said container for controlling the escape of dispensable material from said container through said nozzle means, e. said valve means including a dip tube extending downwardly into said container from adjacent said nozzle means and rotatable about its axis to selectively open and close a dispensable material outlet opening in at least one of said compartments, and f. means for rotating said dip tube.
Claim 2
Dependent Claim
98 words
An aerosol dispenser, comprising: a. a container having a plurality of compartments therein, b. each of said compartments adapted to contain a dispensable material, c. nozzle means on said container, d. valve means in said container for controlling the escape of dispensable material from said container through said nozzle means, e. said valve means including a dip tube extending downwardly into said container from adjacent said nozzle means and rotatable about its axis to selectively open and close a dispensable material outlet opening in at least one of said compartments, and f. means for rotating said dip tube.
Claim 3
Dependent Claim
41 words
The aerosol dispenser of claim 1 further characterized in that: a. said dip tube extends to a free end adjacent the bottom of the container and has an axial bore therein opening at said free end into one of said compartments.
Claim 4
Dependent Claim

The aerosol dispenser of claim 2 further characterized in that: a. said dip tube extends through a sleeve forming a portion of at least one of said compartments, b. said dispensible material outlet opening being formed in said sleeve and a radial opening being formed through said dip tube for selective registry with said sleeve opening.
Claim 6
Dependent Claim
64 words
The aerosol dispenser of claim 4 further characterized in that: a. said sleeve forms a portion of a plurality of said compartments, b. a dispensible material outlet opening being formed through said sleeve from each of said compartments, and c. radial openings formed in said dip tube for selective registry with said sleeve openings to permit the escape of dispensible material from prescribed compartments.
Claim 7
Dependent Claim
46 words
The aerosol dispenser of claim 4 further characterized in that: a. said sleeve means defines the axis of a plurality of compartments radiating outwardly from said sleeve means, b. a dispensible material outlet opening being formed radially through said sleeve means into each of said compartments.
Claim 8
Dependent Claim
22 words
