Abstract

A strip-form toilet cleaning product comprising a width (B), a height (H) and a thickness (S), wherein the ratio between width (B), height (H) and thickness (S) is between 1:1:0.01 and 1:0.1:0.2, a first extruded phase and at least one second extruded phase, wherein at least the contour of a contact surface ( 4, 4 a, 4 b ) along the center axis ( 8 ) takes the form of a sine wave which has an amplitude of A 1,O , wherein the ratio of amplitude to width (B) A 1,O :B amounts to between 1:10 and 1:25 and the periodic length of the sine wave corresponds to 0.1-1 times the width (B) of the toilet cleaning product.

First claim

What is claimed is:

1. A strip-form toilet cleaning product for application in the interior of a toilet bowl comprising
a width (B), a height (H) and a thickness (S), wherein the ratio between width (B), height (H) and thickness (S) is between 1:1:0.01 and 1:0.1:0.2,
a first extruded phase and
at least one second extruded phase, wherein the first phase differs from at least the second phase, wherein however all the phases comprise at least one adhesion promoter at least on the side of the toilet cleaning product to be applied onto the toilet bowl and
the first phase and at least the second phase have a contact surface with one another wherein
at least the contour of a contact surface along the center axis takes the form of a sine wave which has an amplitude of A 1,O , wherein the ratio of amplitude to width (B) A 1,O :B amounts to between 1:10 and 1:25 and the periodic length of the sine wave corresponds to 0.1-1 times the width (B) of the toilet cleaning product.

2. The strip-form toilet cleaning product according to claim 1 , characterized in that the first phase and the at least second phase have the same width (B).

3. The strip-form toilet cleaning product according to claim 1 , characterized in that the first phase and at least the second phase have substantially the same height.

4. The strip-form toilet cleaning product according to claim 1 , characterized in that the first phase and at least the second phase have substantially the same thickness (S).

5. The strip-form toilet cleaning product according to claim 1 , characterized in that the two widthwise sides which define the toilet cleaning product have a contour which substantially corresponds to the contour of the contact surface.

6. The strip-form toilet cleaning product according to claim 1 , characterized in that at least one adhesion promoter is added to the toilet cleaning product.

7. The strip-form toilet cleaning product according to claim 1 , characterized in that it contains at least one surfactant.

8. The strip-form toilet cleaning product according to claim 7 , characterized in that the at least one surfactant is selected from the group of nonionic surfactants, anionic surfactants and mixtures thereof.

9. The strip-form toilet cleaning product according to claim 1 , characterized in that it contains further ingredients conventionally present in toilet cleaning products, preferably selected from the group comprising acids, bases, salts, thickeners, antimicrobial active substances, preservatives, complexing agents, bitter substances, polymers, colorants, scents, perfume boosters, fillers, builders, bleaching agents, corrosion inhibitors, erosion regulators, enzymes, microorganisms, active substances for biofilm removal, active substances for inhibiting lime deposits, active substances for reducing adhesion of soiling, active substances for improving processability and mixtures thereof.

10. The strip-form toilet cleaning product according to claim 1 , characterized in that the toilet cleaning product comprises at least one adhesion promoter in the form of a single- or double-sided adhesive strip or an adhesive applied over an extensive area or in spots, which is arranged on the side of the toilet cleaning product which is applied in the interior of the toilet bowl.

11. A method for producing strip-form, multiphase toilet cleaning products, in particular the strip-form toilet cleaning product according to claim 1 , consisting of at least two phases comprises the steps:
a) mixing the components in each case for the individual phases,
b) extruding the individual strands for the various phases,
c) bringing the individual strands together in a common die or in each case separate dies, such that a contact surface is formed between the strands, wherein the die or dies carries/carry out an oscillatory movement.

12. A method for producing strip-form, multiphase toilet cleaning products according to claim 1 , consisting of at least two phases comprises the steps:
a) mixing the components in each case for the individual phases,
b) extruding the individual strands for the various phases,
c) bringing the individual strands together in a common die or in each case separate dies, such that a contact surface is formed between the strands, wherein the extruders with the die or dies carry out a simultaneous oscillatory movement.

13. An individual dispensing pouch storing the strip-form toilet cleaning product according to claim 1 , characterized in that the strip-form toilet cleaning product adheres with at least one flat side to the interior surface of the individual dispensing pouch, wherein the adhesion of the toilet cleaning product to the interior surface of the pouch is lower than the adhesion of the toilet cleaning product to a ceramic surface in the interior of a toilet bowl.
