Abstract

In order to improve the reliability of cleanly dispensing the first tissue in a pop-up dispensing tissue container, a relatively high strength sacrificial top sheet is interfolded with the tissue clip. The sacrificial top sheet is adhered to the underside of a removable surfboard in the top of the container, such that when the surfboard is removed to access the tissues, the sacrificial sheet is simultaneously removed, which causes the first tissue to pop up into a ready position for subsequent dispensing by the user.

Claims (12)

1. A tissue product comprising a clip of interfolded tissues within a container, said container having a top through which the tissues are withdrawn by a user, said top comprising a pop-up tissue dispensing opening and a detachable surfboard overlaying the dispensing opening, said clip of interfolded tissues having an interfolded sacrificial top sheet adhered to the surfboard, said top sheet having a geometric mean tensile strength substantially greater than the geometric mean tensile strength of the other tissues within the clip, wherein upon removal of the surfboard by the user, the sacrificial top sheet is also removed.

2. The product of claim 1 wherein the sacrificial top sheet is a synthetic sheet.

3. The product of claim 1 wherein the sacrificial top sheet is paper.

4. The product of any of the preceding claims wherein the sacrificial top sheet has a geometric mean tensile strength of about 1000 grams or greater per 3 inches of width.

5. The product of claim 1 wherein the sacrificial top sheet has a geometric mean tensile strength from about 1000 to about 20,000 grams per 3 inches of width.

6. The product of claim 1 wherein the sacrificial top sheet has a geometric mean tensile strength from about 1500 to about 15,000 grams per 3 inches of width.

7. The product of claim 1 wherein the sacrificial top sheet has a geometric mean tensile strength from about 2000 to about 15,000 grams per 3 inches of width.

8. The product of claim 1 wherein the sacrificial top sheet is visually distinct from the tissues within the clip.

9. The product of claim 8 wherein the sacrificial top sheet is a different color than the tissues within the clip.

10. The product of claim 8 wherein the sacrificial top sheet contains printed matter.

11. The product of claim 1 wherein the size of the sacrificial top sheet is a different than the size of the tissues.

12. The product of claim 1 wherein the top of the container comprises a poly film having a pop-up dispensing opening therein and the surfboard overlays the poly film dispensing opening.
