Abstract (en)
[origin: EP0399357A2] A device for cleaning clogged drains, consisting of a conventional aerosol can with outlet valve and protective cap, is to be improved in that it can be refilled with an environmentally friendly propellant and has an operator-friendly actuation lock. This is achieved in that the aerosol can (2) is filled with compressed air and, for its refilling, the region (14), enclosing the valve pin (13), of the protective cap (3) is extended as a free-standing cylindrical tube-shaped adaptor (16), and the actuation lock can be released by relative rotation of aerosol can (2) and protective cap (3). <IMAGE>
