Abstract

A web of multi-dose cleaning products and method of manufacturing the same is disclosed. The web includes a carrier sheet including first and second pluralities of depressions, a first plurality of pouches, and a second plurality of pouches. Each of the pouches is positioned in a respective depression in the carrier sheet. The first plurality of pouches contain a first cleaning composition, and the second plurality of pouches contain a second cleaning composition. A first end of the carrier sheet is folded over a second end of the carrier sheet so that each multi-dose cleaning product is defined by at least an overlapping pair of the first and second pouches and an overlapping pair of the first and second depressions.

First claim

What is claimed is:

1. A web of multi-dose cleaning products comprising:
a carrier sheet having a first end, a second end, a first plurality of depressions, and a second plurality of depressions;
a first plurality of pouches disposed in the first plurality of depressions and containing a first cleaning composition;
a second plurality of pouches disposed in the second plurality of depressions and containing a second cleaning composition; and
the first end of the carrier sheet being folded over the second end of the carrier sheet so that each multi-dose cleaning product is defined by at least one pair of overlapping first and second pouches and at least one pair of overlapping first and second depressions, the first and second ends of the carrier sheet being sealed together to inhibit the ingress of foreign material.

2. The web of claim 1 , the first and second pluralities of pouches being made of a water-soluble material.

3. The web of claim 2 , the carrier sheet being made of a water-resistant material.

4. The web of claim 3 , comprising:
each of the first plurality of pouches having a first holder filled with the first cleaning composition and a first lid covering an open end of the first holder; and
each of the second plurality of pouches having a second holder filled with the second cleaning composition and a second lid covering an open end of the second holder.

5. The web of claim 3 , the first and second holders being thermoformed to the carrier sheet.

6. The web of claim 1 , at least one of the multi-dose cleaning products being defined by at least two pairs of overlapping first and second pouches and two pairs of overlapping first and second depressions.

7. The web of claim 6 , comprising a plurality of weakened tear lines formed in the carrier sheet such that multi-dose cleaning products are separately detachable from the web.

8. The web of claim 1 , wherein:
each of the first plurality of pouches includes a first lid made of a water-soluble material;
each of the second plurality of pouches includes a second lid made of a water-soluble material; and
each overlapping pair of first and second pouches is arranged such that the first lid of the first pouch faces and is immediately adjacent to the second lid of the second pouch.

9. The web of claim 1 , a first face of the carrier sheet being sealed directly to a second face of the carrier sheet to inhibit the ingress of foreign material.

10. The web of claim 1 , the first cleaning composition being at least one of a dishwashing detergent, a laundry detergent, a water softener, or a rinse aid.

11. A multi-dose cleaning product comprising:
a folded carrier sheet having a first end with a first depression and a second end with a second depression, the first end overlapping and being sealed to the second end to define a sealed interior volume;
a first pouch within the sealed interior volume and containing a first cleaning composition; and
a second pouch within the sealed interior volume and containing a second cleaning composition.

12. The multi-dose cleaning product of claim 11 , the first pouch being formed by a first water-soluble holder filled with the first cleaning composition and a first water-soluble lid covering an open end of the first water-soluble holder.

13. The multi-dose cleaning product of claim 12 , the second pouch being formed by a second water-soluble holder filled with a second cleaning composition and a second water-soluble lid covering an open end of the second water-soluble holder.

14. The multi-dose cleaning product of claim 13 , the folded carrier sheet being made of a water-resistant material.

15. The multi-dose cleaning product of claim 14 , the first and second water-soluble holders being thermoformed to the folded carrier sheet.

16. The multi-dose cleaning product of claim 11 , wherein:
the first pouch includes a first lid made of a water-soluble material;
the second pouch includes a second lid made of a water-soluble material; and
the first lid of the first pouch faces and is immediately adjacent to the second lid of the second pouch.

17. The multi-dose cleaning product of claim 11 , a first face of the carrier sheet being sealed directly to a second face of the carrier sheet to inhibit the ingress of foreign material.

18. The multi-dose cleaning product of claim 11 , the first pouch being disposed in the first depression in the first end of the carrier sheet and the second pouch being disposed in the second depression in the second end of the carrier sheet, such that the first pouch overlaps the second pouch.

19. The multi-dose cleaning product of claim 11 , the first cleaning composition being at least one of a dishwashing detergent, a laundry detergent, a water softener, or a rinse aid.
