Abstract

Abstract of Disclosure A cosmetic application and mixing system for liquid or semi-solid cosmetic products comprising, in combination: (a) a reservoir for containing the cosmetic product, the reservoir having an internal diameter D1, and at least one open end having threaded engaging means having pitch P1 on the outer surface thereof; (b) an applicator for the cosmetic product comprising a cosmetic applicator portion on a stationary curved rod attached to a cap, the cosmetic applicator portion having a free end, and the cap having threaded engaging means of pitch P1, designed to mate with threaded engaging means having pitch P1 on the outer surface of the reservoir, wherein when the cap is rotated to affix or remove it from the reservoir, the free end of the cosmetic applicator portion moves in a pitch circle having a pitch P2 and a diameter D2, wherein P1 = P2 and D1 > D2.

Claims 
     
         1.  A cosmetic application and mixing system for cosmetic products comprising, in combination: (a)  a reservoir for containing the cosmetic product, the reservoir having an internal diameter D1, and at least one open end having threaded engaging means having pitch P1 on the outer surface thereof; (b)  an applicator for the cosmetic product comprising a cosmetic applicator portion on a stationary curved rod attached to a cap, the cosmetic applicator portion having a free end, and the cap having threaded engaging means of pitch P1, designed to mate with threaded engaging means having pitch P1 on the outer surface of the reservoir, wherein when the cap is rotated to affix or remove it from the reservoir, the free end of the cosmetic applicator portion moves in a helical pitch circle having a pitch P2 and a diameter D2, wherein P1 = P2 and D1 &gt; D2. 
         
     
     
       
         2. 
       
       The cosmetic system of  claim 1  wherein the reservoir is a cylindrical vial. 
     
     
       
         3. 
       
       The cosmetic system of  claim 2  wherein D1 ranges from 0.1 to 2 inches. 
     
     
         4.  The cosmetic system of  claim 3  wherein P1 and P2 range from 0.001 to 0.5 inch. 
         
     
     
         5.  The cosmetic system of  claim 1  wherein the cosmetic applicator portion is a flocked applicator. 
     
     
       
         6. 
       
       The cosmetic system of  claim 5  wherein the free end of the flocked applicator has an angled surface on one side thereof. 
     
     
         7.  The cosmetic system of  claim 6  wherein the angled surface forms about a 35 to 65 o  angle to a plane which passes through the axis of the rod. 
     
     
         8.  The cosmetic system of  claim 6  wherein the angled surface is positioned on the inner portion of the stationary curved rod. 
         
     
     
         9.  The cosmetic system of  claim 1  wherein D1 is 0.35 to 0.55 inch. 
     
     
         10.  The cosmetic system of  claim 8  wherein the stationary curved rod is bent at an angle of 1 to 20 o .  
     
     
         11.  The cosmetic system of  claim 10  wherein D1 = D2. 
     
     
         12.  The cosmetic system of  claim 11  wherein D1 &gt; D2. 
     
     
         13.  The cosmetic system of  claim 1  wherein the cosmetic product is lipstick.
