Abstract
Abstract A centrifugal aerosol dispenser assembly capable of dispersing a cloud of particulate aerosol material in a predetermined geometrical configuration. The dispenser assembly is formed of two parts, a mount and a dispenser. An ejector mechanism having a portion thereof on said mount and a portion thereof on said dispenser expels the dispenser from said mount with a spin motion. A plurality of dispensing compartments located within the dispenser contains the particulate material therein, and, at a predetermined time after ejection thereof releases its contents in a predetermined geometrical configuration due to the centrifugal forces acting thereon.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
A centrifugal aerosol dispenser assembly comprising a mount and a dispenser operatively attached thereto, means for ejecting said dispenser from said mount with a spin motion, a first portion of said ejection means connected to said mount, a second portion of said ejection means connected to said dispenser, a plurality of compartments located within said dispenser, at least one of said compartments being made up of an actuator section and a dispensing section, said dispensing section having removable sides thereon, means located within said actuator section for releasably securing said sides to said dispensing section and means located within another of said compartments for activating said releasing means at a preselected time whereby at said preselected time after ejection of said dispenser from said mount, said releasing means releases said sides of said dispensing section and allows the expulsion of the contents of said dispensing section to take place in a predetermined geometrical configuration.
Claim 2
Dependent Claim
154 words
A centrifugal aerosol dispenser assembly comprising a mount and a dispenser operatively attached thereto, means for ejecting said dispenser from said mount with a spin motion, a first portion of said ejection means connected to said mount, a second portion of said ejection means connected to said dispenser, a plurality of compartments located within said dispenser, at least one of said compartments being made up of an actuator section and a dispensing section, said dispensing section having removable sides thereon, means located within said actuator section for releasably securing said sides to said dispensing section and means located within another of said compartments for activating said releasing means at a preselected time whereby at said preselected time after ejection of said dispenser from said mount, said releasing means releases said sides of said dispensing section and allows the expulsion of the contents of said dispensing section to take place in a predetermined geometrical configuration.
Claim 3
Dependent Claim
87 words
A centrifugal aerosol dispenser assembly as defined in claim 1 wherein said second portion of said ejection means comprises means for securing said dispenser to said mount, an inner sleeve fixedly secured to said dispenser and encompassing said securing means, means interposed between said mount and said inner sleeve for exerting a force against said inner sleeve and means for releasing said securing means and thereby permitting said force exerting means to propel said sleeve in conjunction with said dispenser in a direction away from said mount.
Claim 4
Dependent Claim
54 words
A centrifugal aerosol dispenser assembly as defined in claim 2 wherein said first portion of said ejection means comprising an outer sleeve fixedly secured to said mount and encompassing said inner sleeve and means interposed between said inner sleeve and said outer sleeve for maintaining alignment between said inner sleeve and said outer sleeve.
Claim 5
Dependent Claim
67 words
A centrifugal aerosol dispenser assembly as defined in claim 3 wherein said inner sleeve has a pin mounted on the external surface thereof and said outer sleeve has a spiral groove located on the inner surface thereof, said pin and said groove being in operative engagement with one another in order to impart said spin motion to said dispenser upon ejection of said dispenser from said mount.
Claim 6
Dependent Claim
58 words
A centrifugal aerosol dispenser assembly as defined in claim 4 wherein said dispensing section has a cover thereon, said cover having a groove located thereon, one end of said sides of said dispensing section being situated in said groove and the other end thereof being held in position by said means for releasably securing said sides in place.
Claim 7
Dependent Claim
23 words
A centrifugal aerosol dispenser assembly as defined in claim 5 wherein said sides of said dispensing section are made of a spring-like material.
Claim 8
Dependent Claim
35 words
A centrifugal aerosol dispenser assembly as defined in claim 6 wherein said dispenser further comprises a shaft centrally located therein, said cover being secured to said shaft and thereby holding said dispensing section in place.
Claim 9
Dependent Claim
41 words
A centrifugal aerosol dispenser assembly as defined in claim 7 wherein said means for releasably securing said sides of said dispensing section in place are in the form of a plurality of movable arms engaging said other end of said sides.
Claim 10
Dependent Claim
27 words
A centrifugal aerosol dispenser assembly as defined in claim 8 wherein said means for securing said dispenser to said mount is in the form of a bolt.
Claim 11
Dependent Claim
20 words
A centrifugal aerosol dispenser assembly as defined in claim 9 wherein said outer sleeve is made of a semi-rigid material.
