Abstract

A cartridge assembly for use in a dispenser assembly of a household appliance. The cartridge assembly including a first cartridge with a first treating chemistry reservoir. The first cartridge having one of a first engagement portion or a first receiving portion. A second cartridge having a second treating chemistry reservoir. The second cartridge having the other of the first engagement portion or the first receiving portion and wherein the first cartridge is coupled to the second cartridge when the first engagement portion is received within the first receiving portion.

What is claimed is: 
     
         1 . A cartridge assembly for use in a dispenser assembly of a household appliance, the cartridge assembly comprising:
 a first cartridge with a first treating chemistry reservoir, the first cartridge having one of a first engagement portion or a first receiving portion; and   a second cartridge having a second treating chemistry reservoir, the second cartridge having the other of the first engagement portion or the first receiving portion;   wherein the first cartridge is coupled to the second cartridge when the first engagement portion is received within the first receiving portion.   
     
     
         2 . The cartridge assembly of  claim 1 , further comprising a third cartridge with a third treating chemistry reservoir, the third cartridge having one of a second engagement portion or a second receiving portion. 
     
     
         3 . The cartridge assembly of  claim 2 , wherein the second cartridge includes the other of the second engagement portion or the second receiving portion and wherein the third cartridge is coupled to the second cartridge when the second engagement portion is received within the second receiving portion. 
     
     
         4 . The cartridge assembly of  claim 3 , wherein the first cartridge, the second cartridge, and the third cartridge couple in a puzzle-like manner. 
     
     
         5 . The cartridge assembly of  claim 3 , further comprising a wrapper configured to span a periphery of the first cartridge, the second cartridge, and the third cartridge. 
     
     
         6 . The cartridge assembly of  claim 2 , further comprising a vent and wherein the vent is located on an upper surface of at least of the second cartridge or the third cartridge. 
     
     
         7 . The cartridge assembly of  claim 6 , wherein the vent fluidly couples at least one of the second cartridge and the third cartridge directly to ambient. 
     
     
         8 . The cartridge assembly of  claim 6 , wherein the vent comprises a membrane. 
     
     
         9 . The cartridge assembly of  claim 1 , wherein the cartridge assembly further comprises lower corners of the cartridge assembly that oppose upper corners of the cartridge assembly and wherein the lower corners of the cartridge assembly have a rounded taper shape configured to engage with a set of guide members of the dispenser assembly. 
     
     
         10 . The cartridge assembly of  claim 1 , the cartridge assembly further comprises lower corners of the cartridge assembly that oppose upper corners of the cartridge assembly and wherein the upper corners have a different shape from the lower corners, wherein the different shape prevents upside down insertion of the cartridge assembly. 
     
     
         11 . The cartridge assembly of  claim 1 , wherein the cartridge assembly includes a front face and a back face, a handle includes a groove located on the front face and back face of the cartridge assembly. 
     
     
         12 . The cartridge assembly of  claim 11 , wherein the handle is formed when the first cartridge, the second cartridge, and the third cartridge are coupled. 
     
     
         13 . The cartridge assembly of  claim 1 , wherein that of the first treating chemistry reservoir contains a first treating chemistry and the second treating chemistry reservoir contains a second treating chemistry and the first treating chemistry and the second treating chemistry are different types of treating chemistry. 
     
     
         14 . The cartridge assembly of  claim 13 , wherein at least one fluid outlet port is fluidly coupled to each of the first treating chemistry reservoir and the second treating chemistry reservoir. 
     
     
         15 . The cartridge assembly of  claim 1 , wherein the cartridge further comprises one or more receiving notches configured to receive one or more resilient members of the dispenser assembly. 
     
     
         16 . The cartridge assembly of  claim 15 , wherein the one or more receiving notches are configured to engage the one or more resilient members in a snap-fit configuration. 
     
     
         17 . A dispensing system for a household appliance having a treating chamber, the dispensing system comprising:
 the cartridge assembly of  claim 1 ; and   a dispenser assembly includes a cartridge receptacle having a set of guide members configured to align the cartridge assembly with the cartridge receptacle, the dispenser assembly configured to selectively fluidly couple dispense from at least one of the first treating chemistry reservoir and the second treating chemistry reservoir.   
     
     
         18 . The dispensing system of  claim 17 , wherein the set of guide members comprises a first guide extending along a side of the cartridge receptacle and a second guide extending along a side of the cartridge receptacle, and wherein the second guide is opposite of the first guide. 
     
     
         19 . The dispensing system of  claim 18 , wherein the first guide and the second guide are displaceable arms configured to displace upon insertion of the cartridge assembly into the dispenser assembly. 
     
     
         20 . The cartridge assembly of  claim 17 , wherein the set of guide members are displaced by lower corners of the cartridge assembly.
