Abstract

There is disclosed an interfold multi-panel clip of sheet material and interfold multi-panel dual webs which dual webs are more easily separated into clips. The dual web is comprised of two webs having staggered sheets. At the point of clip separation an additional perforation line in one web divides a separation sheet extending between the clips into two partial sheets which partial sheets are confined between the folds of the separated clips. Preferably the additional perforation line is located at an interfold line and divides the separation sheet into 3/8 and 5/8 partial sheets.

Claims

1. An interfolded multi-panel clip having a first end and a second end comprising a first web and a second web each being divided into full length sheets by perforation lines wherein the webs are laid together so that the sheets and perforation lines are staggered, and the webs are folded accordion-fashion along fold lines into panels each having a length so that the perforation lines are located intermediate the fold lines, wherein the first end of the clip terminates with a first full length sheet of the first web and a second partial length sheet of the second web, wherein an exposed portion of a panel of the first sheet overlays a portion of a panel of the second partial length sheet at the first end of the clip, and wherein the panel portion of the second sheet is longer than the panel portion of the first sheet.

2. The clip of claim 1, wherein the panel portion of the second partial length sheet is a full panel length and the exposed panel portion of the first sheet is a half panel length.

3. The clip of claim 2, wherein the full length sheets are folded into four panels, and the second partial length sheet is 5/8 of the length of the first full length sheet.

4. The clip of claim 1, wherein the second end of the clip terminates with a third full length sheet of the first web and a fourth partial length sheet of the second web wherein an exposed portion of a panel of the third sheet overlays its own adjacent full length panel which adjacent panel overlays a panel of the fourth sheet.

5. The clip of claim 4, wherein the panel portion of the second partial length sheet is a full length panel, and the exposed panel portion of the first sheet is a half panel length.

6. The clip of claim 5, wherein the full length sheets are folded into four panels, and the second partial length sheet is 5/8 of the length of the first full length sheet.

7. An interfolded multi-panel dual web to be divided into clips comprising a first web and a second web each being divided into full length sheets by ordinary perforation lines wherein the webs are laid together so that the sheets and ordinary perforation lines are staggered, and the webs are folded accordian-fashion along fold lines into panels each having a length so that the ordinary perforation lines are located intermediate the fold lines, wherein the second web has an additional perforation line which is located between a fold line and an ordinary perforation line of the first web and divides a separation sheet extending between the clips into a first partial sheet and a second partial sheet.

8. The dual web of claim 7, wherein the dual web is folded into four panels, and the additional perforation line is located on the fold line so that the separation sheet is divided into the first partial sheet that is 3/8 the length of a full length sheet and the second partial length sheet that is 5/8 of the length of the first full length sheet.
