Modular cooler system

Abstract

A cooler system includes a main body and a lid. A divider is removably coupled to an interior of the main body. A container is removably suspended within the interior of the main body by a lip resting on a rim of the main body and an upper edge of the divider. An accessory is removably coupled to an external flange of the main body.

What is claimed is: 
     
         1 . A cooler system comprising:
 a main body;   a lid; and   a divider removably couplable to an interior of the main body by a first ridge intersecting a first groove.   
     
     
         2 . The cooler system of  claim 1 , wherein the divider is removably couplable to the interior of the main body by a second ridge intersecting with a second groove. 
     
     
         3 . The cooler system of  claim 2 , wherein the first and second grooves are located in respective first and second sidewalls of the interior of the main body. 
     
     
         4 . The cooler system of  claim 3 , wherein the divider comprises a chamber containing a coolant. 
     
     
         5 . The cooler system of  claim 3 , further comprising:
 a removable container including a lip,   wherein the lip is configured to suspend the removable container from a top surface of the divider or from a rim of the main body.   
     
     
         6 . A cooler system comprising:
 a main body;   a flange projecting outwardly from the main body;   a lid; and   an accessory removably couplable to the flange by an attachment fitting, the attachment fitting including a first tab configured to engage a first recess in the flange.   
     
     
         7 . The cooler system of  claim 6 , wherein:
 the lid is movable between an open position and a closed position; and   when the lid is in the closed position and the attachment fitting is coupled to the flange, the lid holds the first tab in engagement with the first recess.   
     
     
         8 . The cooler system of  claim 7 , wherein the attachment fitting includes a second tab configured to engage a second recess in the flange. 
     
     
         9 . The cooler system of  claim 8 , wherein the first recess is located in an upper face of the flange, and the second recess is located in a lower face of the flange. 
     
     
         10 . The cooler system of  claim 9 , wherein the attachment fitting comprises:
 a body extending from a sidewall portion of the accessory;   a first projection extending from the body, the upper projection including the first tab; and   a second projection extending from the body, the lower projection including the second tab.   
     
     
         11 . The cooler system of  claim 9 , wherein the attachment fitting further comprises:
 an engagement surface on the body configured to bear against an edge of the flange.   
     
     
         12 . The cooler system of  claim 11 , wherein the engagement surface is located between the first projection and the second projection. 
     
     
         13 . The cooler system of  claim 12 , wherein the first recess comprises a first side substantially perpendicular to the upper face of the flange. 
     
     
         14 . The cooler system of  claim 13 , wherein the first recess comprises a second side oriented at an acute angle to the upper face of the flange. 
     
     
         15 . The cooler system of  claim 14 , wherein the first side and the second side form boundaries of a slot oriented generally parallel to an edge of the flange. 
     
     
         16 . The cooler system of  claim 15 , wherein the edge of the flange is closer to the first side than to the second side. 
     
     
         17 . The cooler system of  claim 16 , wherein the second recess comprises a third side oriented at an acute angle to the lower face of the flange. 
     
     
         18 . The cooler system of  claim 17 , wherein the acute angle of the third side with respect to the lower face of the flange is less than the acute angle of the second side with respect to the upper face of the flange. 
     
     
         19 . The cooler system of  claim 18 , wherein the attachment fitting comprises injection molded plastic. 
     
     
         20 . The cooler system of  claim 19 , wherein the accessory and the attachment fitting are molded as a unitary component.
