ABSTRACT:
This composite insert for injecting a liquid product under pressure into a member provided with an internal bore comprises first and second coaxial rigid sockets surrounding the outlet aperture of the container filled with said product, the first socket comprising an external flange and the second socket comprising an internal shoulder adapted to engage an internal abutment element of the member, the front end of the second socket comprising an external flange. A flexible resilient sleeve fits around the second socket and bears with its ends against the external flanges of the first and second sockets so that when an axial pressure is exerted against the second socket by means of the internal abutment element of the member the second socket is sunk more or less into the first socket, thus causing an elastic deformation of the sleeve which develops a bead engaging in a fluid-tight manner the wall of the inner bore of the member. This insert is suitable notably for lubricating and cleaning dental handtool holders.
