BRIEF DESCRIPTION OF THE DRAWINGS

[0094] The following figures illustrate embodiments of the present invention:

[0095] FIG. 1a cleaning agent shaped body, the cross section of which extending orthogonally to the bearing surface has the shape of an arc of a circle;

[0096] FIG. 1b cleaning agent shaped body, the cross-section of which extending orthogonally to the bearing surface has the shape of an arc of an ellipse;

[0097] FIG. 2 use of a cleaning agent shaped body according to the prior art; and

[0098] FIG. 3 use of a cleaning agent shaped body according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0099] FIG. 1a shows a cleaning agent shaped body 10 according to the invention. The cleaning agent shaped body 10 has a bearing surface 12 and a dome surface 15. The dome surface is spherical.

[0100] FIG. 1b shows a cleaning agent shaped body 10 according to the invention. The cleaning agent shaped body 10 has a bearing surface 12 and a dome surface 15. The dome surface is ellipsoidal.

[0101] FIG. 2 shows the use of a cleaning agent shaped body 10 according to the prior art.

[0102] The cleaning agent shaped body 10 is designed as a sphere. The cleaning agent shaped body 10 has no bearing surface 12.

[0103] If the cleaning agent shaped body 10 is introduced into a toilet cistern, the cleaning agent shaped body 10 in the cistern can move in the water reservoir in the toilet cistern, but in particular on the base 50 of the toilet cistern. The cleaning agent shaped body 10 can be flushed out through the outlet 55 of the toilet cistern by this movement, for example a rolling movement.

[0104] FIG. 3 shows the use of a cleaning agent shaped body 10 according to the invention. The cleaning agent shaped body 10 has, in particular, a bearing surface 12.

[0105] Due to the cleaning agent shaped body 10 according to the invention having a bearing surface 12 in addition to a dome surface 15, the cleaning agent shaped body 10 can rest in the cistern so as to have the bearing surface 12 on the base 50 of the toilet cistern, without moving in the toilet cistern. Uneven rinsing behavior is prevented. Furthermore, the cleaning agent shaped body 10 is prevented from being flushed out of the cistern through the drain 55 of the toilet cistern by a rolling movement. It was also advantageously observed that the cleaning agent shaped body 10, if the bearing surface 12 thereof does not hit the base 50 after said body has been introduced into the water reservoir and has dropped down to the base 50 of the toilet cistern, moves, by rolling in the toilet cistern under the usual flow conditions, into a position in which the bearing surface 12 rests on the base. This rolling movement is promoted in particular by a design of the shaped body in which said body has, orthogonally to the bearing surface, a cross section in the form of an arc of a circle or an arc of an ellipse, preferably in the form of an arc of a circle.

[0106] Once the bearing surface 12 of the cleaning agent shaped body 10 is resting on the base 50, the cleaning agent shaped body 10 can no longer be flushed out of the cistern through the drain 55 by means of a rolling movement.
