Abstract
By reducing the overlap distance O of the interfolded sheets in the upper layer of a stack of interfolded sheets, sheet tears and/or multiple dispensing can be avoided for the initial sheets dispensed. By increasing the overlap distance O of the interfolded sheets in the lower layer of a stack of interfolded sheets, fallback of the subsequent sheets can be avoided. To maximize the number of sheets that can be placed into the same sized dispenser, the folded width of all sheets in the stack should be substantially the same. The interfolded stack is especially useful in an upright dispenser to improve sheet dispensing, but can also be utilized in a flat dispenser.
Claims14
A product comprising:
- an interfolded stack containing a plurality of individual interleaved sheets folded from a sheet material;
- each of the sheets having substantially the same overall folded width and having an overlap distance O representing the distance a preceding sheet is in interleaved contact with a subsequent sheet;
- the stack having an upper layer and a lower layer;
- and
- wherein the overlap distance O is less for the sheets in the upper layer than for the sheets in the lower layer and wherein the overlap distance for the sheets in the upper layer progressively increases from an initial overlap distance Oi to a final overlap distance Of.
