For the packaging of Hyalu B5 Anti-Wrinkle Eye Serum, La Roche-Posay relied on Medicos’ expertise, featuring an original combination of a dropper and a roll-on designed to meet the requirements of targeted and precise application.
This solution is based on a PP roll-on pipette with a stainless-steel ball, complemented by a nitrile bulb, a PP collar and a PP protective transport cap. The 15ml bottle is in mass dyed molded glass.
The originality of the system lies in the functional combination of the dropper’s precise dosing gesture with the roll-on’s targeted application, specifically adapted to the eye contour area.
From an industrial standpoint, Medicos successfully addressed the challenge of fully automated assembly of the stainless-steel ball and the dropper system, ensuring reliability, repeatability and production performance.
With sustainability in mind, the PP, stainless-steel and glass components are recyclable. The bulb, currently made of nitrile, will soon be replaced by a TPE version recyclable within the PP stream, while maintaining identical functional and sensory properties.
The specific development brings together two historic areas of expertise at Medicos: droppers and roll-on solutions, both derived from established ready-to-use ranges.
Medicos’ roll-on range is based on housing ball, a glass or stainless-steel ball, a PP or RPP cap with a tubular glass bottle. Two standard ball diameters are available - D7.5 mm and D10 mm - corresponding respectively to capacities of 5 to 10 ml and 10 to 20 ml. Flow reducers can be integrated depending on application requirements.
As far as droppers are concerned, the Medicos’ range includes a tubular glass pipette or a specific PP pipette, fitted with a nitrile, butyl or TPE teat, and a smooth or ribbed PP or RPP cap. Different pipette geometries and orifice diameters allow precise adaptation to cosmetic and dermocosmetic applications. These droppers can be combined with tubular glass, molded glass or plastic bottles in various capacities.
Tamper-evident rings and PP pipette protectors complement this offering.
The breadth of available diameters, lengths and capacities enables a wide range of combinations, further enhanced by multiple finishing options. Caps and housing ball can be mass-dyed, with additional finishes such as lacquering, metallization or aluminum sleeving available, along with decorative options including hot stamping or engraving. The bottle can also be customized by silk-screen printing, hot stamping or lacquering.
