Abstract
A compressed unit dose toilet cleaning tablet for use with a wand. The unit dose contains surfactant, organic acid, and an organic acid buffering agent and is compressed into a tablet or puck that dissolves in toilet water after cleaning. The tablet has a top surface, a bottom surface, a height extending from the top surface to the bottom surface, and a diameter. The top surface has an indentation adapted to receive and engage with a wand. A ratio of the height to the diameter of the tablet is between 0.2 and 0.3. A kit contains a plurality of the tablets and a wand.
Claims20
A compressed, unit dose, toilet cleaning tablet comprising:
- a surfactant;
- an organic acid;
- and
- an organic acid buffering agent, wherein:
- the toilet cleaning tablet has a top surface, a bottom surface, a height extending between the top surface and the bottom surface that is at least about 0.5 inches,
- the toilet cleaning tablet has a diameter that is less than or equal to 2.375 inches,
- the top surface has an indentation adapted to receive and engage with a wand, the indentation having a diameter of from 0.25 inches to 1.5 inches, and the indentation having a depth that is at least 25% of the height, and
- wherein a ratio of the height to the diameter is between 0.2 and 0.3.
A kit comprising:
- a plurality of toilet cleaning tablets, each of the toilet cleaning tablets comprising a surfactant, an organic acid, and an organic acid buffering agent, wherein:
- each of the toilet cleaning tablets has a top surface, a bottom surface, a height extending between the top surface and the bottom surface that is at least about 0.5 inches,
- each of the toilet cleaning tablets has a diameter that is less than or equal to 2.375 inches,
- the top surface has an indentation, the indentation having a diameter of from 0.25 inches to 1.5 inches, and the indentation having a depth that is at least 25% of the height, and
- a ratio of the height to the diameter is between 0.2 and 0.3;
- and
- a wand adapted to engage in the indentation in the top surface of each of the toilet cleaning tablets.
A unit dose, toilet cleaning composition comprising:
- a surfactant in an amount of from about 10% to about 30% by weight, based on the total weight of the toilet cleaning composition;
- an organic acid in an amount of from about 20% to about 60% by weight, based on the total weight of the toilet cleaning composition;
- and
- an organic acid buffering agent in an amount of from about 5% to about 40% by weight, based on the total weight of the toilet cleaning composition, wherein:
- the toilet cleaning composition is compressed into a puck having a top surface, a bottom surface, a height extending between the top surface and the bottom surface that is at least about 0.5 inches,
- the puck has a diameter that is less than or equal to 2.375 inches,
- the top surface has an indentation adapted to receive and engage with a wand, the indentation having a diameter of from 0.25 inches to 1.5 inches, and the indentation having a depth that is at least 25% of the height, and
- a ratio of the height to the diameter is between 0.2 and 0.3.
