Abstract

A spatially optimized form of detergent tablets, which is provided with the greatest possible volume while being useable in the largest possible number of dosing chambers of known dishwashers available on the European market. Said detergent tablets comprise a bottom surface and a top surface. The places of the two surfaces are not parallel across at least half of the size of the smaller surface.

Claims

1. A laundry detergent or cleaning composition tablet, characterized in that the tablet has a bottom face and a top face, the two faces not being plane-parallel over at least half of the size of the smaller face.

2. The laundry detergent or cleaning composition tablet as claimed in claim 1, characterized in that the bottom face and top face are not plane-parallel over the entire size of the smaller face.

3. The laundry detergent or cleaning composition tablet as claimed in claim 1, characterized in that the bottom face is planar to an extent of at least 50% over the whole face.

4. The laundry detergent or cleaning composition tablet as claimed in claim 1, characterized in that the top face is planar to an extent of at least 35%.

5. The laundry detergent or cleaning composition tablet as claimed in claim 1, characterized in that the non-plane-parallel proportions of the bottom face and top face form with one another an angle of from 10 to 300.

6. The laundry detergent or cleaning composition tablet as claimed in claim 1, characterized in that at least one lateral limiting face which connects bottom face and top face is nonvertical over at least 60% of its height.

7. The laundry detergent or cleaning composition tablet as claimed in claim 1, characterized in that it has four lateral limiting faces of which one is nonvertical over at least half of its height.

8. The laundry detergent or cleaning composition tablet as claimed in claim 1, characterized in that it has a multiphase structure.

9. The laundry detergent or cleaning composition tablet as characterized in claim 1, wherein the faces have beveled edges.

10. The laundry detergent or cleaning composition tablet as characterized in claim 1, wherein the tablet has a density about 1100 kgm⁻

3.

11. The laundry detergent or cleaning composition tablet as characterized in claim 1, wherein the tablet has a multilayer structure.

12. The laundry detergent or cleaning composition tablet as characterized in claim 11, wherein one of the layers is substantially dissolved in the pre-wash.

13. A laundry detergent or cleaning composition tablet characterized in that the tablet has a bottom face and a top face, the two faces not being plane parallel over at least half of the size of the smaller face and characterized in that the top face has at least one cavity into which a separately produced molding can be introduced.

14. The laundry detergent or cleaning composition tablet as characterized in claim 13, in which the separately produced molding substantially dissolves during a pre-wash cycle of a dish or clothes washer and the rest of the tablet substantially dissolves during a main wash cycle of a dish or clothes washer.

15. The laundry detergent or cleaning composition tablet as claimed in claim 13, characterized in that the separately produced molding has a top face which is not entirely planar.

16. The laundry detergent or cleaning composition tablet as claimed in claim 15, characterized in that the top face of the separately produced molding has convex curvature, the edge of the top face of the separately produced molding preferably being aligned parallel to the bottom face of the laundry detergent or cleaning composition tablets.

17. A laundry detergent or cleaning composition tablet, characterized in that the tablet has a bottom face and a top face, the two faces not being plane-parallel over at least half of the size of the smaller face and that the non-plane portions of the bottom face and top face form with one another an angle of from 10 to 500.

18. The laundry detergent or cleaning composition tablet as claimed in claim 17, characterized in that the tablet has a multilayer structure.

19. The laundry detergent or cleaning composition tablet as claimed in claim 17, characterized in that the top face has at least one cavity into which a separately produced molding can be introduced.

20. The laundry detergent or cleaning composition tablet as claimed in claim 19, characterized in that the separately produced molding substantially dissolves during a pre-wash cycle of a dish or clothes washer and the tablet substantially dissolves during a main wash cycle of a dish or clothes washer.
