Abstract: Container with a modular structure consisting of an internal disposable assembly, or refill, comprising a glass vial, preferably intended to contain nail polish formulations, and a brush stem fixed through the glass vial lid, this disposable assembly designed to adapt into an external non-disposable assembly, comprising a lower safe handling base, having a cavity in which the vial is inserted, and a hollow upper body to externally grasp the vial lid to open and close the vial and, at the same time, to grasp the brush stem upper portion, providing appropriate handling of the thus formed brush assembly applicator, reducing the amount of discarded material, encouraging single-person use and safety.

Abstract: Container with a modular structure, comprising at least one internal assembly and one external assembly; the internal assembly being susceptible to association with the external assembly; the external assembly comprising at least one base and at least one upper body, the base being susceptible to association with the upper body; the internal assembly comprising at least one vial and at least one lid, the vial being susceptible to association with the lid; the vial comprising, at least one means for being removably coupled to the base; the lid comprising at least one means for being removably coupled to the upper body; the vial and the lid being disposable and the base and the upper body being reusable.
