Pack Allows Preservative-Free Formula

RPC Bramlage Bellignat has developed and patented a perfectly hermetic sealing system that makes it possible to protect a sterile cosmetic formula without preservatives throughout the product’s use. The D.E.F.I. (exclusive intact formula device) distribution system guarantees the product remains sterile throughout its life even after opening. The system therefore enables large size packs to be created for increased consumer convenience compared to mono-dose, uni-dose and single dose formats.

The four-piece cap includes a membrane that rises when the tube is squeezed and resumes its normal position when pressure is released from the tube. These are high-precision parts manufactured to one hundredth of a millimeter. They provide cohesion with the entire unit, while the lid is perfectly sized to the cap with no gaps, and closed with a tamper-proof clip that is removed when the tube is first opened. The closure system was developed in cooperation with and exclusively for French skincare brand Avene of the Pierre Fabre Laboratories, which produces a range of skincare products dedicated to sensitive skin. The Bellignat factory in France manufactures a wide variety of jars and closures.
