Sponge having an open cavity
First Claim
1. A method in which a user manipulates a sponge (20),wherein said sponge is foam-generating and includes at least one cavity (22), distinct from the pores of the sponge (20), capable of allowing the introduction of a dishwashing liquid inside the sponge (20) to impregnate the sponge (20), the cavity (22) having a bottom (24) inside the sponge (20), and emerging on the other hand on a surface (26) of the sponge (20) while forming an opening (28) such that the maximum distance between two points of the contour of the opening (28) is comprised between 3 and 25 mm, andwherein a large part of a dishwashing liquid poured into the cavity (22) is then stored in the pores of the sponge (20) situated close to the bottom (24) of the cavity (22),wherein a volume of at least 90% of the dishwashing liquid is absorbed in the sponge (20),wherein the user releases a quantity of dishwashing liquid by compressing said sponge (20), whereby foam is generated, andwherein the sponge has an absorption speed of a reference volume of 2 ml of a dishwashing liquid with the viscosity of 900 cps at 25°
- C. deposited on the surface of the sponge with a volume of 140 cm3 and previously moistened with water, of less than 5 minutes.

Abstract
The present invention relates to a sponge (20) including at least one cavity (22), distinct from the pores of the sponge 5 (20), capable of allowing the introduction of a liquid inside the sponge (20) to impregnate the sponge (20), the cavity (22) preferably having a bottom (24) inside the sponge (20), and emerging on the other hand on a surface (26) of the sponge (20) while forming an opening (28) such that the maximum distance between two points of the contour of the opening (28) is comprised between 3, preferably 5, still more preferably 8, and 25, preferably 20, still more preferably 15 mm or still more preferably 12 mm.

1. A method in which a user manipulates a sponge (20),
wherein said sponge is foam-generating and includes at least one cavity (22), distinct from the pores of the sponge (20), capable of allowing the introduction of a dishwashing liquid inside the sponge (20) to impregnate the sponge (20), the cavity (22) having a bottom (24) inside the sponge (20), and emerging on the other hand on a surface (26) of the sponge (20) while forming an opening (28) such that the maximum distance between two points of the contour of the opening (28) is comprised between 3 and 25 mm, and wherein a large part of a dishwashing liquid poured into the cavity (22) is then stored in the pores of the sponge (20) situated close to the bottom (24) of the cavity (22), wherein a volume of at least 90% of the dishwashing liquid is absorbed in the sponge (20), wherein the user releases a quantity of dishwashing liquid by compressing said sponge (20), whereby foam is generated, and wherein the sponge has an absorption speed of a reference volume of 2 ml of a dishwashing liquid with the viscosity of 900 cps at 25° - C. deposited on the surface of the sponge with a volume of 140 cm3 and previously moistened with water, of less than 5 minutes.

12. A method of manipulating a sponge,
the sponge being foam-generating, the sponge comprising at least one cavity that is distinct from any pores on the sponge, the at least one cavity comprising a bottom located inside the sponge and an opening located on a surface of the sponge, and the maximum distance between the bottom and the contour of the opening is between 3 and 25 mm, wherein the opening is configured to receive dishwashing liquid and allow a quantity of dishwashing liquid to impregnate the inside of the sponge, the at least one cavity is configured to guide the dishwashing liquid toward the inside of the sponge, the sponge being configured so dishwashing liquid penetrates the inside structure of the sponge, wherein a volume of at least 90% of the dishwashing liquid is absorbed in the sponge, and the sponge having a water retention capacity greater than 20 g/100 cm3, as measured after saturation of the sponge, after pressure is applied underwater, and after wringing out on a plane surface inclined to 45° - for one minute;
the method comprising; pouring a dose of dishwashing liquid into the at least one cavity to impregnate the sponge, manipulating the sponge so the dishwashing liquid penetrates the inside structure of the sponge, wherein a volume of at least 90% of the dishwashing liquid is absorbed in the sponge, and compressing the sponge to generate a foam from the absorbed dishwashing liquid. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
