Abstract

A web of cleaning products and a method of manufacturing the same is disclosed. The web includes a carrier sheet having a plurality of depressions each filled, and in direct contact with, at least one cleaning composition. A plurality of internal lids that correspond with the plurality of depressions are sealed to the carrier sheet in a manner covering the plurality of depressions. Additionally, a plurality of external lids that correspond with the plurality of internal lids are sealed to the carrier sheet and cover the plurality of internal lids. The carrier sheet and external lids may be made of a water-resistant material, and the internal lids may be made of a water-soluble material. In one embodiment, the internal lids may be omitted, and instead the depressions be filled with water-soluble pouches, each of which contains a respective dose of a cleaning composition.

First claim

What is claimed is:

1. A web of cleaning products comprising:
a water-resistant carrier sheet having a circular outer peripheral edge, a mean outer diameter in a range of approximately 10-35 cm, and a plurality of pie-shaped depressions arranged about a center of the water-resistant carrier sheet such that an outer edge of each of the plurality of pie-shaped depressions follows the circular outer peripheral edge of the water-resistant carrier sheet, each filled and in direct contact with at least one cleaning composition;
a plurality of internal lids corresponding with the plurality of depressions and being sealed to the carrier sheet to cover the plurality of depressions; and
a plurality of external lids corresponding with the plurality of internal lids and being sealed to the carrier sheet to cover the plurality of internal lids.

2. The web of claim 1 , each of the plurality of external lids including an outer peripheral edge defined by a weakened tear line allowing a user to individually remove the plurality of external lids from the web one at a time.

3. The web of claim 2 , each of the plurality of external lids including a pull tab that projects outwardly of an outer peripheral edge of the carrier sheet and facilitates removal of the associated external lid.

4. The web of claim 1 , each of the plurality of depressions being divided into two or more cavities each filled with a different cleaning composition.

5. The web of claim 1 , the external lids being made of a water-resistant material.

6. The web of claim 5 , the internal lids being made of a water-soluble material.

7. The web of claim 1 , each of the plurality of external lids being separately sealed to the carrier sheet such that removal of one of the external lids does not compromise the seal of the remaining external lids.

8. The web of claim 1 , each external lid covering a larger surface area of the carrier sheet than its corresponding internal lid.

9. The web of claim 1 , the carrier sheet being made of a rigid material.

10. A web of cleaning products comprising:
a water-resistant carrier sheet having a circular outer peripheral edge and a plurality of pie-shaped depressions arranged about a center of the water-resistant carrier sheet such that an outer edge of each of the plurality of pie-shaped depressions follows the circular outer peripheral edge of the water-resistant carrier sheet and wherein the circular outer peripheral edge of the water-resistant carrier sheet has a mean outer diameter in a range of approximately 10-35 cm;
a plurality of water-soluble pouches each positioned in a corresponding one of the plurality of pie-shaped depressions and containing at least one cleaning composition; and
a plurality of water-resistant external lids sealed to the carrier sheet and covering the plurality of pie-shaped depressions.

11. The web of claim 10 , each of the plurality of water-resistant external lids including an outer peripheral edge defined by a weakened tear line allowing a user to individually remove the plurality of water-resistant external lids from the web one at a time.

12. The web of claim 11 , each of the plurality of water-resistant external lids including a pull tab that projects outwardly of an outer peripheral edge of the water-resistant carrier sheet and facilitates removal of the associated water-resistant external lid.

13. The web of claim 10 , each of the plurality of pie-shaped depressions containing two or more water-soluble pouches.

14. The web of claim 10 , the at least one cleaning composition being at least one of a dishwashing detergent, a water softener, or a rinse aid.

15. The web of claim 10 , each of the plurality of water-resistant external lids being separately sealed to the water-resistant carrier sheet such that removal of one of the external lids does not compromise the seal of the remaining external lids.

16. The web of claim 10 , the water-resistant carrier sheet being made of a rigid material.

17. The web of claim 10 , the plurality of water-resistant external lids being sealed directly to the water-resistant carrier sheet and not being sealed to plurality of water-soluble pouches.

18. The web of claim 10 , each of the plurality of water-soluble pouches having a pie-shape corresponding to that of the pie-shaped depression in which the water-soluble pouch is positioned.

19. A method of making a web of cleaning products, the method comprising:
forming a plurality of pie-shaped depressions in an upper surface of a first water-resistant carrier sheet, the carrier sheet having a circular outer peripheral edge, a mean outer diameter in a range of approximately 10-35 cm, and the plurality of pie-shaped depressions arranged about a center of the water-resistant carrier sheet such that an outer edge of each of the plurality of pie-shaped depressions follows the circular outer peripheral edge of the water-resistant carrier sheet;
filling each of the plurality of depressions with at least one cleaning composition;
positioning a film to cover the first carrier sheet and sealing the film to the upper surface of the first carrier sheet about a rim of each of the plurality of depressions;
cutting the film to define a plurality of internal lids, each of the plurality of internal lids covering a corresponding one of the plurality of depressions;
removing an area of waste material produced by cutting the film to expose portions of the upper surface of the first carrier sheet;
positioning a second carrier sheet to cover the first carrier sheet and sealing the second carrier sheet to the exposed portions of the upper surface of the first carrier sheet; and
forming a plurality of weakened tear lines in the second carrier sheet to define a plurality of external lids, each of the plurality of external lids covering a corresponding one of the plurality of internal lids.

20. The method of claim 19 , each of the plurality of external lids including a pull tab that projects outwardly of an outer peripheral edge of the first carrier sheet and allows a user to individually remove the plurality of external lids from the web.

21. The method of claim 19 , comprising cutting the first carrier sheet to form the circular outer peripheral edge.

22. The method of claim 21 , forming each of the plurality of weakened tear lines along respective radial lines extending from a center of the circular shape of the first carrier sheet.

23. The method of claim 19 , comprising forming each of the plurality of depressions with two or more cavities, and filling the two or more cavities with different cleaning compositions.

24. The method of claim 19 , the second carrier sheet being made of a water-resistant material.

25. The method of claim 24 , the film being made of a water-soluble material.
