1. A metallic roll-on container for applying a product onto an external surface, comprising:
a metallic container body extending along a longitudinal axis from a closed bottom end to an open top end, wherein said metallic container body comprises an aluminum material;
at least one arcuate-shaped sidewall of said metallic container body that defines an upper opening with a first diameter, a lower opening with a second diameter, and a maximum inner diameter between said upper and lower openings;
a roller sphere positioned in said open top end of said metallic container body and seated at least partially between said upper opening and said lower opening to define a chamber between said roller sphere and said at least one arcuate-shaped sidewall, wherein a diameter of said roller sphere is greater than said first diameter and greater than said second diameter, and said diameter of said roller sphere is less than said maximum inner diameter, wherein said diameter of said roller sphere is between approximately 0.8% to 1.3% larger than said first diameter of said upper opening;
wherein, in a first extended position, said roller sphere is seated against said upper opening of said at least one arcuate-shaped sidewall, and said chamber is in fluid communication with said container and can receive a product stored in said container; and
wherein, in a second depressed position, said roller sphere is seated against said lower opening of said at least one arcuate-shaped sidewall, and said chamber is no longer in fluid communication with said product stored in said container, and wherein said roller sphere rotates to allow the application of said product in said chamber to an external surface.
