Hair brush and related method for storing and applying hair care treatments

Abstract

A hair brush may include a body, a number of bristles extending away from the body, and a replaceable cartridge removably attached to the body. The cartridge may include a housing, a reservoir positioned at least partially within the housing, and an applicator positioned at least partially within the housing. The reservoir may be configured to store a hair care treatment therein and may include a first porous material. The applicator may be configured to apply the hair care treatment to hair of a user and may include a second porous material. The hair care treatment may be optimized for delivery via the reservoir and the applicator.

That which is claimed is: 
     
         1 . A hair brush comprising:
 a body;   a plurality of bristles extending away from the body; and   a cartridge removably attached to the body, the cartridge comprising:
 a housing; 
 a reservoir positioned at least partially within the housing and configured to store a hair care treatment therein, the reservoir comprising a first porous material; and 
 an applicator positioned at least partially within the housing and configured to apply the hair care treatment to hair of a user, the applicator comprising a second porous material. 
   
     
     
         2 . The hair brush of  claim 1 , wherein the reservoir and the applicator abut one another and are in fluid communication with one another. 
     
     
         3 . The hair brush of  claim 1 , wherein the first porous material is a fibrous material, and wherein the second porous material is a sintered porous plastic. 
     
     
         4 . The hair brush of  claim 1 , wherein the first porous material has a first porosity, wherein the second porous material has a second porosity, and wherein the first porosity is greater than the second porosity. 
     
     
         5 . The hair brush of  claim 4 , wherein the first porosity is within a range of between approximately 59% and approximately 79%, and wherein the second porosity is within a range of between approximately 33% and approximately 53%. 
     
     
         6 . The hair brush of  claim 1 , wherein the reservoir is positioned entirely within the housing, and wherein the applicator extends out of the housing and away from the body. 
     
     
         7 . The hair brush of  claim 6 , wherein the applicator comprises a base and a plurality of protrusions extending from the base, wherein the base is positioned at least partially within the housing, and wherein the protrusions are positioned at least partially outside of the housing. 
     
     
         8 . The hair brush of  claim 1 , further comprising a latch movably positioned within the body and configured to move between an unlocked position in which the latch allows removal of the cartridge from the body and a locked position in which the latch inhibits removal of the cartridge from the body. 
     
     
         9 . The hair brush of  claim 8 , wherein the latch comprises a main body and a spring, and wherein the spring is configured to bias the latch toward the unlocked position. 
     
     
         10 . The hair brush of  claim 8 , further comprising a door removably attached to the body, wherein the door is configured to move the latch to the locked position when the door is attached to the body. 
     
     
         11 . The hair brush of  claim 10 , wherein the door comprises a first protrusion configured to engage a second protrusion of the latch to move the latch to the locked position when the door is attached to the body. 
     
     
         12 . The hair brush of  claim 11 , wherein the door further comprises a second protrusion configured to engage the cartridge and inhibit movement of the cartridge relative to the body when the door is attached to the body. 
     
     
         13 . The hair brush of  claim 1 , wherein the cartridge further comprises a hair care treatment loaded in the reservoir, and wherein the hair care treatment comprises at least one of a hair oil, a hair conditioner, a hair serum, or a hair dye. 
     
     
         14 . A cartridge for a hair brush, the cartridge comprising:
 a housing;   a reservoir positioned at least partially within the housing, the reservoir comprising a first porous material;   a hair care treatment loaded in the reservoir; and   an applicator positioned at least partially within the housing and configured to apply the hair care treatment to hair of a user, the applicator comprising a second porous material.   
     
     
         15 . The cartridge of  claim 14 , wherein the reservoir and the applicator abut one another and are in fluid communication with one another. 
     
     
         16 . The cartridge of  claim 14 , wherein the first porous material is a fibrous material, and wherein the second porous material is a sintered porous plastic. 
     
     
         17 . The cartridge of  claim 14 , wherein the first porous material has a first porosity, wherein the second porous material has a second porosity, and wherein the first porosity is greater than the second porosity. 
     
     
         18 . A hair brush comprising:
 a body;   a plurality of bristles extending away from the body; and   a cartridge removably attached to the body, the cartridge comprising:
 a housing; 
 a first porous member positioned at least partially within the housing; 
 a hair care treatment loaded in the first porous member; and 
 a second porous member positioned at least partially within the housing and configured to apply the hair care treatment to hair of a user. 
   
     
     
         19 . The hair brush of  claim 18 , wherein the first porous member is formed of a first material having a first porosity, wherein the second porous member is formed of a second material having a second porosity, and wherein the first porosity is greater than the second porosity. 
     
     
         20 . The hair brush of  claim 18 , wherein the hair care treatment comprises at least one of a hair oil, a hair conditioner, a hair serum, or a hair dye.
