Abstract: A tamper-evident closure (10) for a container (20) is provided. The closure (10) comprises a first portion (25) including inner (35) and outer (45) parts, and a second portion (30). The outer part (45) is movable relative to the inner part (35) from a first position in which the outer part (45) is immediately adjacent the second portion (30) to a second position in which there is an empty unobstructed gap (G) therebetween. The inner (35) and outer (45) parts are adapted to become irreversibly locked in the second position so that the outer part (45) cannot be moved back to the first position to close the gap (G). A combination of such a closure (110) with an in-bore filament (100) connectable to a container (120) is also provided.

Abstract: A method and assembly for detecting the presence of a failure in a protective coating on the surface of a metal body which comprises causing an electrolyte to make contact with the protective coating, and making comparison of the electric current generated through the electrolyte(a) between the metal body and a reference-electrode immersed in the electrolyte, and(b) between the same reference-electrode and a similation-electrode immersed in the electrolyte and having a working surface of the same metal as that of the metal body.
