A metallic roll-on container for applying a product onto an external surface has been granted a patent (Publication Number: US11957229B2). The container comprises a metallic body made of aluminum material with an arcuate-shaped sidewall defining upper and lower openings. A roller sphere, larger than the openings, creates a chamber for product application. The container includes a shoulder for a cap with an interference fit to depress the roller sphere for product application. The method for manufacturing involves forming the container body from metallic material, pressing the roller sphere into the sidewall, and releasing the deformation to retain the sphere within the body.

Furthermore, the metallic roll-on container system includes a roller sphere, arcuate-shaped sidewall, and a shoulder for cap connection with an interference fit. The system allows for the application of liquid products on the skin efficiently. The cap's inwardly-extending curl forms the interference fit with the shoulder, ensuring proper functioning of the container. The metallic container body and cap are made of materials with a Young's Modulus greater than 50 GPa, enhancing durability and performance for user-friendly product application.
