Modular Multi-Chamber Fluid Dispenser

Abstract

A modular and multi-chamber hair dye dispenser and kit including the same are provided. Namely, the dispenser comprises a first and second chamber configured to each hold a fluid substance and threadedly engage one another. A pressure activated gate is disposed between the chambers and configured to selectively permit fluids held therein to mix upon screwing the chambers into one another. A removable spacer may be disposed between the chambers to prevent breach of the gate until desired. An outlet secured within an open front end of the first chamber is configured to dispense mixed fluid via one or more openings and, as desired, receive an interchangeable applicator. In a kit, fluid substances may comprise hair coloring agent and a developer, activator, or oxidizer.

What is claimed is: 
     
         1 . A modular, multi-chamber fluid dispenser assembly, comprising:
 a first chamber configured to hold a fluid substance, such first chamber having a front end defining an opening and a rear end defining a threaded rear opening;   a second chamber axially aligned with the first chamber and configured to hold a fluid substance, the second chamber having a front end defining an opening configured to threadedly engage the threaded rear opening of the first chamber and a sealed rear end;   a pressure activated gate securely disposed between the first and second chambers operative to selectively permit fluid exchange between the first and second chambers;   an outlet secured within the open front end of the first chamber; and   at least one interchangeable applicator removably securable to the outlet.   
     
     
         2 . The assembly of  claim 1 , further comprising a replaceable lid defined by at least one sidewall extending from a blunt top. 
     
     
         3 . The assembly of  claim 1 , further comprising a removable spacer externally disposed between the first and second chambers and operative to prevent breach of the pressure activated gate and fluid exchange between the chambers. 
     
     
         4 . The assembly of  claim 1 , wherein the first and second chambers are resilient and compressible. 
     
     
         5 . The assembly of  claim 1 , wherein at least one of the first and second chambers is at least partially transparent. 
     
     
         6 . The assembly of  claim 5 , wherein the at least one partially transparent chamber comprises a transparent window operative to visibly expose any fluid substance held by such chamber. 
     
     
         7 . The assembly of  claim 1 , wherein at least one of the first and second chambers is opaque. 
     
     
         8 . The assembly of  claim 1 , wherein the dispenser is configured for single use. 
     
     
         9 . The assembly of  claim 1 , wherein the rear end of the second chamber defines an opening secured by a removable cap. 
     
     
         10 . The assembly of  claim 1 , wherein the pressure activated gate is securely disposed in the front end opening of the second chamber. 
     
     
         11 . The assembly of  claim 1 , wherein an outer surface of any of the first and second chambers defines a depression as a means for gripping such chambers. 
     
     
         12 . The assembly of  claim 10 , further comprising at least one additional chamber defining a front and rear opening, configured to align and threadedly engage with the first and second chambers in sequence, and further configured to hold a fluid substance; and
 for each at least one additional chamber, an additional pressure activated gate securely disposed in the front opening of each additional chamber operative to selectively permit fluid exchange with any other chamber.   
     
     
         13 . A hair dye kit, comprising:
 a modular, multi-chamber hair dye dispenser, comprising:
 a) a first chamber comprising a fluid hair coloring agent, such first chamber having a front end defining an opening and a rear end defining a threaded rear opening; 
 b) a second chamber comprising a fluid hair dye developer, such second chamber axially aligned with the first chamber and having a front end and a sealed rear end, the front end defining an opening configured to threadedly engage the threaded rear opening of the first chamber; 
 c) a pressure activated gate securely disposed between the first and second chambers operative to selectively permit mixing of the hair coloring agent and hair dye developer between the first and second chambers upon screwing the first and second chambers into one another; 
 d) a removeable spacer operative to prevent breach of the gate until desired; and 
 e) an outlet secured within the open front end of the first chamber; 
   at least one interchangeable applicator selected from the group consisting of a bristled brush, a sponge, and a comb, each removably securable to the outlet; and   a replaceable lid defined by at least one sidewall extending from a blunt top and configured to cover the outlet and any applicator secured to the outlet.   
     
     
         14 . The kit of  claim 13 , wherein the first and second chambers are resilient and compressible. 
     
     
         15 . The kit of  claim 13 , wherein the first and second chambers are washable and refillable. 
     
     
         16 . The kit of  claim 13 , wherein an outer surface of at least one of the first and second chambers defines a depression as a means for gripping such chambers. 
     
     
         17 . A kit, comprising:
 a modular, multi-chamber fluid dispenser, comprising:
 a) a first chamber comprising a first fluid, such first chamber having a front end defining an opening and a rear end defining a threaded rear opening; 
 b) a second chamber comprising a second fluid, such second chamber axially aligned with the first chamber and having a front end and a sealed rear end, the front end defining an opening configured to threadedly engage the threaded rear opening of the first chamber; 
 c) a pressure activated gate securely disposed between the first and second chambers operative to selectively permit mixing of the first and second fluids between the first and second chambers upon screwing the first and second chambers into one another; 
 d) a removeable spacer operative to prevent breach of the gate until desired; and 
 e) an outlet secured within the open front end of the first chamber; 
   at least one interchangeable applicator removably securable to the outlet; and   a replaceable lid defined by at least one sidewall extending from a blunt top and configured to cover the outlet and any applicator secured to the outlet.   
     
     
         18 . The kit of  claim 17 , wherein the first and second chambers are resilient and compressible.
