Benefits of technology

[0015] The invention also contemplates the use of the novel stack of absorbent sheet products in a variety of dispensers. At present, a dispenser having downwardly-directed opening is preferred, in which the stack of absorbent sheet pro

Problems solved by technology

Paper napkins that are single folded only (sometimes also called “half-folded” when the fold bisects the napkin, or “off-folded” when it does not) have the disadvantage that, in order to achieve a given total absorbency, the basis weight of the unfolded napkin sheet must be relatively hig

Embodiment Construction

[0026] FIGS. 1(a), 1(b) and 6 depict the above-discussed “quarter-folded” embodiment of the invention. As seen in FIGS. 1(a) and 1(b), the interfolding of adjacent sheets is such that any given napkin within the stack receives, between a pair of adjacent panels of the given napkin, a pair of adjacent panels of each of an upper and a lower napkin within the stack.

[0027] Such an interfolding arrangement is shown in the context of single folded paper towels, in U.S. Pat. Nos. 1,427,420 and 1,632,446. A quarter-folded interleave arrangement has been described before in connection with pop-up tissue dispensers (see EP 0 286 538 B1 and EP 0 302 382 A1). Web interfolding machines are described in U.S. Pat. Nos. 3,285,599 and 3,291,479, the entireties of which patents are hereby expressly incorporated by reference.

[0028] Whereas the embossed folded absorbent sheet products according to the invention are preferably paper napkins, as discussed in U.S. Pat. No. 5,300,347, facial tissue is ra...

Abstract

A stack of interfolded absorbent sheet products comprises a plurality of absorbent sheets each of which is itself folded at least twice about axes that are perpendicular to one another. The absorbent sheets have an embossed surface relief of a predetermined pattern or design. Each of the absorbent sheets within the stack comprises at least one pair of panels sandwiched between a pair of adjacent panels of another of the absorbent sheets in the stack.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a stack of interfolded absorbent sheet products, and preferably, but not necessarily, to a stack of interfolded paper napkins bearing a predetermined pattern imparted by embossing or by formation by the Through-Air Drying (“TAD”) technique. [0003] 2. Description of Related Art [0004] In commercial food service establishments and public restrooms, folded paper products such as paper napkins are typically provided in dispensers from which the products may be withdrawn by the patrons of those establishments. Whereas the highest quality paper napkins are invariably “server-controlled,” i.e., delivered individually by a waiter or waitress, it is nevertheless desired to provide paper products in the user-dispensed application that are perceived as being of relatively higher quality. [0005] Interfolded paper products, and especially interfolded paper napkins, have the advantage that they can be loa...
