Reservoir for urea solution and method for manufacturing such a reservoir

Abstract

A reservoir or container for a urea solution that includes an upper shell having at least one upper pillar-type structure, a lower shell having at least one lower pillar-type structure spatially arranged opposite to and connected to the at least one upper pillar-type structure to define an internal container volume to receive the urea solution, and a heater in the internal container volume to control the temperature of the urea solution. The at least one lower pillar-type structure is arranged adjacent to the heater.

What is claimed is: 
     
         1 . A container for a urea solution, the container comprising:
 an upper shell having at least one upper pillar-type structure;   a lower shell having at least one lower pillar-type structure spatially arranged opposite to and connected to the at least one upper pillar-type structure to define an internal container volume to receive the urea solution; and   a heater in the internal container volume to control the temperature of the urea solution, wherein the at least one lower pillar-type structure is arranged adjacent to the heater.   
     
     
         2 . The container of  claim 1 , wherein the upper shell and the lower shell are composed of plastic. 
     
     
         3 . The container of  claim 1 , wherein the upper shell and the lower shell are comprise of by injection moulded plastic. 
     
     
         4 . The container of  claim 1 , wherein the upper shell and the lower shell are connected to one another by welding. 
     
     
         5 . The container of  claim 1 , wherein the at least one upper pillar-type structure and the at least one lower pillar-type structure are connected to one another by welding. 
     
     
         6 . The container of  claim 1 , wherein the heater is arranged centrally at the bottom of the lower shell. 
     
     
         7 . The container of  claim 1 , wherein the at least one upper pillar-type structure and the at least one lower pillar-type structure are of hollow design. 
     
     
         8 . The container of  claim 1 , wherein the at least one upper pillar-type structure is of hollow design. 
     
     
         9 . The container of  claim 1 , wherein the at least one lower pillar-type structure is of hollow design. 
     
     
         10 . The container of  claim 1 , wherein:
 the at least one upper pillar-type structure is formed integrally with the upper shell; and   the at least one lower pillar-type structure is formed integrally with the lower shell.   
     
     
         11 . The container of  claim 1 , wherein the at least one upper pillar-type structure is formed integrally with the upper shell. 
     
     
         12 . The container of  claim 1 , wherein the at least one lower pillar-type structure is formed integrally with the lower shell. 
     
     
         13 . A method for producing a container for a urea solution, the method comprising:
 providing an upper shell having at least one upper pillar-type structure and a lower shell having at least one lower pillar-type structure; and then   joining the upper shell and the lower shell by connecting the at least one upper pillar-type structure with the at least one lower pillar-type structure to define an internal container volume to receive the urea solution.   
     
     
         14 . The method of  claim 13 , wherein providing the upper shell and the lower shell comprises injection moulding a plastic, respectively. 
     
     
         15 . The method of  claim 13 , wherein joining the upper shell and the lower shell comprises permanently connecting the at least one upper pillar-type structure with the at least one lower pillar-type structure by welding. 
     
     
         16 . The method of  claim 13 , further comprising arranging a heater centrally at the bottom of the lower shell. 
     
     
         17 . A motor vehicle container for a fluid solution, the motor vehicle container comprising:
 an upper shell having an upper pillar-type structure;   a lower shell having a lower pillar-type structure connected to the upper pillar-type structure to define an internal motor vehicle container volume to receive the fluid solution; and   a heater in the internal motor vehicle container volume to control the temperature of the fluid solution, wherein the lower pillar-type structure is arranged adjacent to the heater.   
     
     
         18 . The motor vehicle container of  claim 17 , wherein the upper shell and the lower shell are composed of plastic. 
     
     
         19 . The motor vehicle container of  claim 17 , wherein the heater is arranged centrally at the bottom of the lower shell. 
     
     
         20 . The container of  claim 17 , wherein at least one of the at least one upper pillar-type structure is formed integrally with the upper shell, and the at least one lower pillar-type structure is formed integrally with the lower shell.
