Abstract

There is provided a system for dispensing a plurality of perforated wipes having a perforation detach strength characteristic. The system includes a dispenser having a dispensing force characteristic and including a sealable chamber. The chamber is configured to retain the plurality of perforated wipes therein. A dispensing opening is in communication with the chamber. The opening is adapted to dispense wipes from the plurality of perforated wipes through the opening and out of the dispenser. A wiper blade is positioned in the dispenser to engage at least a portion of the wipes as the wipes dispense through the opening. When dispensing, a ratio of the perforation detach strength characteristic to the dispensing force characteristic is greater than 1:1.

Claims (29)

1. A system for dispensing a plurality of perforated wipes having a perforation detach strength characteristic, comprising:

a dispenser having a dispensing force characteristic and including a sealable chamber, the chamber configured to retain the plurality of perforated wipes therein;

a dispensing opening in communication with the chamber, the opening adapted to dispense wipes from the plurality of perforated wipes through the opening and out of the dispenser;

a wiper blade positioned in the dispenser to engage at least a portion of the wipes as the wipes dispense through the opening; and

wherein the dispensing force characteristic is greater than 0 g/cm and less than about 75 g/cm.

2. The system of claim 1 wherein the dispensing force characteristic is less than about 65 g/cm.

3. The system of claim 1 wherein the dispensing force characteristic is less than about 55 g/cm.

4. The system of claim 1 wherein the dispensing force characteristic is less than about 45 g/cm.

5. The system of claim 1 wherein the dispensing force characteristic is less than about 35 g/cm.

6. The system of claim 1 wherein the wiper blade has a Shore A hardness equal to or less than about 50 durometer.

7. The system of claim 1 wherein the wiper blade has a Shore A hardness equal to or less than about 45 durometer.

8. The system of claim 1 wherein the wiper blade has a Shore A hardness between about 40 durometer and about 30 durometer.

9. A roll of wipes for use in a dispensing system, comprising:

a roll of perforated wipes having a perforation detach strength characteristic, wherein the perforation detach strength characteristic is greater than 55 g/cm.

10. The roll of wipes of claim 9 wherein the perforation detach strength characteristic is greater than about 60 g/cm.

11. The roll of wipes of claim 9 wherein the perforation detach strength characteristic is greater than about 65 g/cm.

12. The roll of wipes of claim 9 wherein the perforation detach strength characteristic is greater than about 75 g/cm.

13. The roll of wipes of claim 9 wherein the perforation detach strength characteristic is greater than about 85 g/cm and less than about 130 g/cm.

14. The roll of wipes of claim 10 in combination with:

a dispenser having a dispensing force characteristic and including a sealable chamber, the chamber configured to retain the roll of perforated wipes therein;

a dispensing opening in communication with the chamber, the opening adapted to dispense wipes from the roll of perforated wipes through the opening and out of the dispenser;

a wiper blade positioned in the dispenser to engage at least a portion of the wipes as the wipes dispense through the opening; and

wherein a ratio of the perforation detach strength characteristic to the dispensing force characteristic is greater than 1:1.

15. The system of claim 14 wherein the ratio is equal to or greater than about 1.5:1.

16. The system of claim 14 wherein the ratio is equal to or greater than about 2:1.

17. The system of claim 14 wherein the ratio is equal to or greater than about 2.5:1.

18. The system of claim 14 wherein the ratio is equal to or greater than about 3:1.

19. The system of claim 14 wherein the ratio is equal to or greater than about 4:1.

20. The system of claim 14 wherein the ratio is equal to or greater than about 5:1.
