<p>The combination of a controlled feed device and surface active material is used for cleaning a toilet. The device comprises a fluid reservoir for a first fluid and components for its release. The device has a first orientation and the release components retain the first fluid in a second orientation. The release components release a part of the first fluid. The controlled feed device (1) has the shape of a fish and has two parts. The head part (2) is drop-shaped and has a first end with a mainly round or ball-shaped form. The start part (3) forms the rear end of the device and is flat, with two outwardly pointing wings (4,5). The two parts are joined by a screw union. The start part can be engaged easily manually and is screwed onto the head part. The head part forms a reservoir for the cleaning fluid and is provided with an outlet (6) and in fact two such outlets. The diameter of these outlets is between 0.5 and 1.5 mm. A hole (7) is provided in the start part, which has a greater cross-section than the outlets.</p> |
