Claim 13:
14. A metallic roll-on container system for applying a liquid product onto a user's skin, comprising:
a metallic container body extending along a longitudinal axis from a closed bottom end to an open top end;
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 located between said upper and lower openings, wherein a thickness dimension of said at least one arcuate-shaped sidewall is constant;
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;
an outwardly-extending shoulder of said metallic container body positioned below said lower opening along said longitudinal axis, said shoulder having a diameter that is larger than said maximum inner diameter; and
a cap selectively connected to said shoulder with an interference fit, wherein, when said cap is selectively connected to said shoulder, said cap presses said roller sphere against said lower opening, wherein said metallic container body and said cap are each made of a material having a Young's Modulus greater than 50 GPa.
