Abstract

Abstract A unit set or assembly of multiple plies includes superimposed top, intermediate and bottom plies as well as a cover ply disposed over the top ply. A flap is removably connected to this cover ply along the line of weakening and underlies the bottom ply. First and second axially aligned holes of different sizes are respectively provided in the bottom and intermediate plies, the size of the bottom ply holes being less than the size of the intermediate ply holes. Adhesive is provided on the flap for securing the top ply thereto, such adhesive extending through the intermediate ply holes. The size difference between the axially aligned holes defines portions of the bottom ply which serve to mask the intermediate ply holes so as to confine the cross-sectional size of the adhesive, which extends therethrough, to the smaller size of the bottom ply holes. Accordingly, the cover ply may be removed from the set while leaving the remaining plies intact, and separation of the top and bottom plies breaks the adhesive and frees the intermediate ply. Thus, a multi-ply set is provided without the need for a removable stub thereby resulting in paper savings and avoiding the need for stub handling and disposal.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 289 words
A unit set of multiple plies, comprising at least superimposed first, second, third and fourth plies, said first ply having a folded flap removably connected along one edge of said top ply by a line of weakening extending along the fold between said flap and said top ply, said third ply having at least one first hole of a predetermined first size lying adjacent one edge thereof, said flap underlying said fourth ply and having a quantity of detachable adhesive thereon securing said first ply to said fourth ply, said fourth ply having at least one second hole of a predetermined second size lying adjacent one edge thereof in axial alignment with said first hole, the size of said second hole being less than the size of said first hole, a portion of said quantity of adhesive extending through said first and second holes and securing said second and fourth plies together along one edge of said second ply, said quantity of adhesive lying inwardly of said first hole by reason of the difference in size between said holes to thereby immobilize said third ply in place, said edges of each said plies lying at a common end of said unit set, and said plies each being devoid of any tear lines which may form a stub, whereby removal of said first ply along said line of weakening leaves said second, third and fourth plies intact, or separation of said second and fourth plies effects a break of said adhesive and frees said third ply from the set while leaving said first and fourth plies interconnected, or removal of said first ply together with separation of said second and fourth plies separates each of said plies from one another.
Claim 2
Dependent Claim 289 words
A unit set of multiple plies, comprising at least superimposed first, second, third and fourth plies, said first ply having a folded flap removably connected along one edge of said top ply by a line of weakening extending along the fold between said flap and said top ply, said third ply having at least one first hole of a predetermined first size lying adjacent one edge thereof, said flap underlying said fourth ply and having a quantity of detachable adhesive thereon securing said first ply to said fourth ply, said fourth ply having at least one second hole of a predetermined second size lying adjacent one edge thereof in axial alignment with said first hole, the size of said second hole being less than the size of said first hole, a portion of said quantity of adhesive extending through said first and second holes and securing said second and fourth plies together along one edge of said second ply, said quantity of adhesive lying inwardly of said first hole by reason of the difference in size between said holes to thereby immobilize said third ply in place, said edges of each said plies lying at a common end of said unit set, and said plies each being devoid of any tear lines which may form a stub, whereby removal of said first ply along said line of weakening leaves said second, third and fourth plies intact, or separation of said second and fourth plies effects a break of said adhesive and frees said third ply from the set while leaving said first and fourth plies interconnected, or removal of said first ply together with separation of said second and fourth plies separates each of said plies from one another.
Claim 3
Dependent Claim 25 words
The unit set according to claim 1, wherein said first, second, third and fourth plies respectively comprise top, first intermediate, second intermediate and bottom plies.
Claim 4
Dependent Claim 26 words
The unit set according to claim 1, wherein a plurality of said aligned first and second holes are provided in said third and fourth plies, respectively.
