Shampoo bottle with replaceable color cartridges

Abstract

A bottle includes a squeezable main chamber configured to dispense a bulk liquid; a cap that dispenses the bulk liquid; and a bulkhead between the main chamber and cap, wherein the bulkhead supports a cartridge containing an additive liquid that is dosed into the bulk liquid.

1 . A method of infusing a hair care product with an additive liquid, comprising:
 providing a squeeze bottle with a main chamber containing a bulk liquid and a cartridge containing an additive liquid; and   squeezing the squeeze bottle to dispense both the additive liquid and bulk liquid from the bottle.   
     
     
         2 . The method of  claim 1 , further comprising dosing the additive liquid into the bulk liquid when squeezing the squeeze bottle. 
     
     
         3 . The method of  claim 1 , further comprising replacing the cartridge with a different cartridge having a different additive liquid. 
     
     
         4 . The method of  claim 1 , comprising dosing the additive liquid into a dosing chamber before dispensing the bulk liquid from the squeeze bottle. 
     
     
         5 . The method of  claim 4 , wherein the bulk liquid passes into the dosing chamber before being dispensed. 
     
     
         6 . The method of  claim 1 , wherein the additive liquid is a dye or coloring agent. 
     
     
         7 . A method of making a squeeze bottle, comprising:
 inserting a cartridge containing an additive liquid into a compartment of a squeeze bottle, wherein the compartment is segregated from a bulk liquid in a squeezable bulk chamber.   
     
     
         8 . The method of  claim 7 , wherein the compartment of the additive liquid is supported from a bulkhead separating the squeezable bulk chamber from a dispensing cap. 
     
     
         9 . The method of  claim 8 , wherein the cap comprises a additive liquid doser for dosing additive liquid into the bulk liquid.
