Method and apparatus for manufacturing a cylindrical container

Abstract

A new and improved process for manufacturing a cylindrical container is disclosed herein. A drawing and ironing process is used to produce a more efficient container. This process eliminates the need for a part, thereby making the process more efficient and cost-effective.

1 . A process for manufacturing a cylindrical container, the process comprising the steps of: 
 drawing and ironing, using a press, at least two metal shells;    forming the container using the at least two metal shells; and,    attaching a valve portion to the container via a brazing process.    
   
   
       2 . The process of  claim 1 , wherein the container has a sidewall, the sidewall having a thickness, the process further comprises the step of: 
 specifying the thickness of the sidewall to withstand hydrostatic pressure.    
   
   
       3 . The process of  claim 2 , wherein the process further comprising the step of: 
 maintaining a substantially consistent thickness via a substantially uniform clearance between the container and an ironing ring.    
   
   
       4 . The process of  claim 1 , wherein drawing and ironing, using a press, at least two metal shells further comprises the step of: 
 drawing and ironing, using a hydraulic press, at least two metal shells.    
   
   
       5 . The process of  claim 1 , wherein drawing and ironing, using a press, at least two metal shells further comprises the step of: 
 drawing and ironing, using a mechanical press, at least two metal shells.    
   
   
       6 . The process of  claim 3 , wherein the method further comprises the step of: 
 attaching a base to the container.    
   
   
       7 . The process of  claim 6 , wherein the process further comprises the step of: 
 increasing the thickness with each run through the process.    
   
   
       8 . The process of  claim 7 , wherein the container is a cylindrical container.  
   
   
       9 . A cylindrical container, the container comprising: 
 a body, the body being formed by a drawing and ironing process; and,    a valve portion, the valve portion being attached to the body via a brazing process.    
   
   
       10 . The container of  claim 9 , wherein the body has a thickness, the thickness being enough to withstand hydrostatic pressure.  
   
   
       11 . The container of  claim 10 , wherein the container further comprises a base, the base attached to the bottom of the container.  
   
   
       12 . The container of  claim 11 , wherein the container is a cylindrical container.  
   
   
       13 . A cylindrical container made in accordance with the process of  claim 1.
