Claim 6:
7. A method for manufacturing a metallic roll-on container for applying a product onto an external surface, comprising:
forming a container body from a slug of metallic material, said slug comprising an aluminum material, wherein said container body extends from a closed bottom end to an open top end, and said container body has at least one arcuate-shaped sidewall that defines an upper opening at said open top end with a first diameter, and a lower opening with a second diameter;
providing a roller sphere having an outer diameter that is larger than said first diameter of said upper opening, wherein said diameter of said roller sphere is between approximately 0.8% to 1.3% larger than said first diameter of said upper opening;
pressing said roller sphere into said at least one arcuate-shaped sidewall at said upper opening to deform said at least one arcuate-shaped sidewall such that said first diameter increases to match said outer diameter of said roller sphere; and
releasing an elastic portion of said deformation of said at least one arcuate-shaped sidewall after said roller sphere passes through said upper opening such that said outer diameter of said roller sphere remains larger than said first diameter of said upper opening, and said roller sphere is retained within said container body.
