Abstract

The present invention is directed to a method of applying a pasty composition for cleaning and/or deodorizing a sanitary ware, wherein the composition is suitable for direct application to the surface of the sanitary ware.

Claims

1. A method of applying a pasty composition for cleaning and/or deodorizing a sanitary ware, said composition being suitable for direct application to the surface of said sanitary ware, wherein the method comprises the steps of:

a) providing a dispensing device comprising a receiving container for housing said pasty composition and a discharge nozzle connected to said receiving container; and

b) dispensing said pasty composition through said discharge nozzle while directly contacting said discharge nozzle to the surface of said sanitary ware.

2. A method according to claim 1, wherein the length of said discharge nozzle is at least about 0.5 cm.

3. A method according to claim 1, wherein the length of said discharge nozzle is at least about 2 cm.

4. A method according to claim 1, wherein said receiving container is made of a deformable material.

5. A method according to claim 4, wherein said receiving container is made of heat sealable thermoplastic materials such as Polyethylene, Polypropylene, Polyethylene Terephthalate, Polyvinyl Chloride, Polystyrene (PS), Polyvinylidene Chloride, and mixtures thereof.

6. A method according to claim 1, wherein said receiving container is in a form selected from the group of tubes, pouches, capsules, boxes, bottles, tottles, envelopes, thermoformed cups, thermoformed blisters, cans, bags, syringes, atomizers, aerosols, pressurized cans, piston-driven cans, and combinations thereof.

7. A method according to claim 6, wherein said receiving container is in the form selected from the group consisting of tubes, pouches, bottles and tottles.

8. A method according to claim 1, wherein said dispensing device is further provided with a peripheral flange.

9. A method according to claim 8, wherein the portion of said peripheral flange extending around the periphery of said discharge nozzle forms a spatula.

10. A method according to claim 1, wherein said pasty composition is dispensed through said discharge nozzle by manual action.

11. A method according to claim 1, wherein the viscosity of said composition is at least about 5.000 mPas, when measured with a TA Instruments/Advanced rheometer AR 1000 at a temperature of about 20°

C. with a gap setting of about 1000 microns, and at a shear rate of about 25 s<sup>−

1</sup>.

12. A method according to claim 1, wherein the viscosity of said composition is comprised between about 5.000 mPas and about 500.000 mPas, when measured with a TA Instruments/Advanced rheometer AR 1000 at a temperature of about 20°

C. with a gap setting of about 1000 microns, and at a shear rate of about 25 s<sup>−

1</sup>.

13. A method according to claim 1, wherein the viscosity of said composition is comprised between about 25.000 mPas and about 100.000 mPas, when measured with a TA Instruments/Advanced rheometer AR 1000 at a temperature of about 20°

C. with a gap setting of about 1000 microns, and at a shear rate of about 25 s<sup>−

1</sup>.

14. A method according to claim 1, wherein said composition comprises a cationic surfactant selected from the group consisting of DEEHMAMS, DEEDMAC, TEEMAMS, dimethyl benzalkonium chloride, and mixtures thereof.

15. A method according to claim 1, which further comprises components selected from the group consisting of acidic compounds, tackifiers, fragrances, thickeners, colorants, dyes, preservatives, additional surfactants, solvents, dye scavengers, adhesion promoters, bleaching systems, and mixtures thereof.

16. A method according to claim 1, wherein said composition is in a form selected from the group consisting of a gel, a paste, and a cream.

17. A method according to claim 1, wherein said sanitary ware is a toilet bowl.

18. A method according to claim 1, whereby said composition is washed away only after at least about 30 rinse cycles.

19. A method according to claim 1, whereby said composition is washed away only after between about 80 and about 200 rinse cycles.
