AI Technical Summary
Technical Problem
Existing pump heads suffer from unreliable closure, difficulty in easy opening after inactivity, poor sealing, high operating forces, and a tendency to jam, especially when dealing with fluids that may dry out or contain preservatives.
Method used
A pump head design featuring an elastic valve with sealing lips that form a point-like contact with the head, allowing for secure sealing and reduced contact pressure, combined with a geometric design that minimizes sticking and enhances sealing performance, even after prolonged inactivity.
Benefits of technology
Ensures reliable sealing against the environment, reduces the risk of contamination, and maintains functionality even after fluid drying, while offering easy operation with lower mechanical forces.
