Abstract
A cosmetic product application member comprises: a rod carrier (40); and a rod (38) defining a first end (70) and a second end (72) that are opposite. The first end (70) of the rod (38) is intended to be assembled in the rod carrier (40). The rod (38) and the rod carrier (40) are manufactured from a plastic material composed of a copolyester, in particular a semi-aromatic copolyester.
Claims17
A cosmetic product application member comprising:
- a rod carrier;
- a rod defining a first end and a second end that are opposite;
- and
- characterized in that the first end of the rod is intended to be assembled in the rod carrier, the rod and the rod carrier being manufactured from a plastic material being composed of a copolyester;
- wherein the rod carrier comprises a screwing ring centered on a rod carrier axis (B-B′) and defining an internal thread and a cylindrical skirt centered on the rod carrier axis, extending at least partially inside the screwing ring and intended to receive the first end of the rod.
A process for manufacturing a rod carrier, the rod carrier being intended to be assembled with a rod to form a cosmetic product application member, the rod being manufactured from a plastic material being composed of a copolyester, the manufacturing process including the following steps:
- providing a rod carrier molding device comprising a die and a central spindle and defining a rod carrier molding cavity;
- and
- injecting a fluid material into the molding cavity;
- and
- solidifying the fluid material in the molding cavity to form the rod carrier;
- characterized in that the fluid material injected into the molding cavity is a copolyester, and wherein the rod carrier comprises a screwing ring centered on a rod carrier axis (B-B′) and defining an internal thread and a cylindrical skirt centered on the rod carrier axis, extending at least partially inside the screwing ring and intended to receive the first end of the rod.
