  • Patent number: 9926695
    Abstract: The invention relates to a toilet cleaner for receiving solid or gel preparations, comprising a plurality of containers for receiving at least one preparation. The containers can be positioned below the toilet rim such that flushing water can flow over the containers when the toilet is flushed, and at least one inlet opening and outlet opening are formed in each container wall for the flushing water. A flushing water conducting element is arranged and configured on the toilet cleaner such that flushing water is supplied to the flushing water conducting element when the toilet is flushed and the flushing water is conducted to the inlet opening of the container. The inlet openings are asymmetrical relative to the vertical axis V of the containers and are arranged at an angle of incidence ? of 1°-60° relative to the longitudinal central axis M.

  • Patent number: 9212476
    Abstract: An applicator for gel-form products, in particular a toilet cleaning product is provided. The applicator includes a receiving space for a first gel-form product, the receiving space comprising a first orifice and a second orifice. The first orifice releases the gel-form product and the second orifice accommodates a piston movable in the receiving space, by means of which the gel-form product may be forced through the first orifice. On the applicator, around the first orifice of the receiving space, at least three spacer elements are arranged that are configured such that, when the applicator is pressed onto a, in particular ceramic, toilet surface to which the gel-form product is to be applied, a gap A is formed between the first orifice and the surface and the gel-form product may flow freely around the spacer elements on discharge.

  • Patent number: 6934973
    Abstract: A dispensing device for dispensing fluids into toilet flushing liquids. The device has a supply container for an active-substance fluid, the supply container having an outlet-side border, an outlet for dispensing active-substance fluid onto a plate-shaped distributing element. The distributing element has a region of action over which flushing liquid flows during the flushing and a connection region, in which the outlet opening of the supply container is arranged. The border is spaced a small distance from the surface of the distributing element. On the top of the distributing element, on the point of connection and directed away from the region of action, is a ventilating channel that is open on top and closed on three sides at its inner end.

  • Publication number: 20040107484
    Abstract: A device for distributing active substance fluids into a toilet flush liquid. A holder suspended from the edge of a toilet bowl holds at least two containers each having its own outlet to distribute its respective active substance fluid into the flush liquid. The containers are designed such that no flush liquid may enter and only active substance may exit the containers. A partial quantity of fluid containing active ingredients is distributed into the flush liquid each time the toilet is flushed.
