Abstract: An aluminum roll-on container, and a method of manufacturing the same, retains a roller sphere for applying a product onto an external surface. The roller sphere can both rotate and move within the container, and a chamber is formed between the container and the roller sphere. In a first position of the roller sphere, the chamber forms a continuous volume with the interior volume of the container such that the chamber receives a product stored in the container volume. Then, in a second position, the chamber forms a continuous volume with the external environment such that rotation of the roller sphere transfers the product from the chamber to an external surface. A relationship between the roller sphere and an upper opening of the container allows the roller sphere to be pressed into the container and then retained in the container.

Abstract: An aluminum roll-on container and a method of manufacturing the same are provided herein where the container retains a roller sphere for applying a product onto an external surface. The roller sphere can both rotate and move within the container, and a chamber is formed between the container and the roller sphere. In a first position of the roller sphere, the chamber forms a continuous volume with the interior volume of the container such that the chamber receives a product stored in the container volume. Then, in a second position, the chamber forms a continuous volume with the external environment such that rotation of the roller sphere transfers the product from the chamber to an external surface. A relationship between the roller sphere and an upper opening of the container allows the roller sphere to be pressed into the container and then retained in the container.
