AI Technical Summary

Technical Problem

Existing sealing materials for fluid product distribution devices, such as those used in pharmaceutical applications, face issues with recyclability, rigidity, assembly difficulty, and compatibility with propellant gases like HFA and HFO, leading to manufacturing complexity and inefficiencies.

Method used

Utilizing Olefin Block Copolymer (OBC) for sealing elements in fluid product distribution devices, particularly in metering valves and pumps, which are more flexible, recyclable, and compatible with propellant gases, allowing for easier assembly and manufacturing.

Benefits of technology

OBC-based sealing elements provide improved recyclability, flexibility, and compatibility with propellant gases, enhancing the manufacturing efficiency and performance of fluid product distribution devices.

Abstract

A fluid product dispensing device comprising a body (100; 100') having a dispensing orifice (110; 110'), a reservoir (1) containing fluid product, a dispensing member (20; 20'), such as a metering valve (20) or a pump (20'), mounted on said reservoir (1), said reservoir (1) being movable relative to said body (100; 100') to actuate said dispensing member (20; 20') and dispense a dose of fluid product through said dispensing orifice (110; 110'), said device comprising at least one sealing element (40, 41, 42) to form a fluid seal, at least one sealing element (40, 41, 42) of said device comprising an OBC (Olefin Block Copolymer).
