El rotating applicator patented of Chanel No. 1 Revitalizing Eye Serum It is a great advance in mechanical engineering. As the main contractor for the project, TNT Group collaborated closely with Chanel and FaiveleyTech to develop the patent-pending rotating, cooling applicator for the Serum, designed to massage and cool the eye area.
The applicator consists of a total of eight components, structured in two interconnected mechanical subassemblies. These sub-assemblies are joined together by two POK rings, which ensure the long-term reliability of the rotating function.
The first subassembly consists of the textured head and tube, both made of stainless steel. The second subassembly comprises two lids and a stem, also made of stainless steel. The upper end is used to assemble the PP insert, which is designed to screw onto the thread of the glass bottle.
The set is combined with the Sulapac® plug produced by FaiveleyTech.
TNT Group engineering teams expertly optimized the texture applicator head, balancing depth and polish. They also ensured a smooth and long-lasting rotation between the two sub-assemblies; The applicator can be reused in a “refill” bottle.
Sulapac® is an alternative material to traditional plastic made from sustainable and responsible raw materials, derived from post-consumer, post-industrial or post-agricultural recycling. Does not leave microplastics. Polyketones (POK or PK) are high-performance thermoplastic polymers.
