A folded paper dispenser napkin is most efficiently used if it is unfolded, thereby making the napkin's entire surface area available to a user. To promote efficiency, it is therefore important to design a folded paper dispenser napkin that can be easily unfolded. If a folded paper dispenser napkin is difficult to unfold, users typically won't bother to unfold it and subsequently tend to compensate for the loss in useful surface area by simply taking more dispenser napkins than they would otherwise need to accomplish the same task; and that results in inefficiency. Folded dispenser napkins having a tab portion are known to be relatively easier to unfold than paper dispenser napkins that do not have tab portions, and it is for this reason that folded dispenser napkins having tab portions typically foster more efficient end use than folded dispenser napkins that do not have a tab portion.
A well known paper-napkin-dispensing apparatus is spring loaded and is intended to dispense one paper-dispenser napkin at a time from a stack of paper-dispenser napkins that have been stacked using the interfolded system. Stacking paper-dispenser napkins using the interfolded system is well known. The interfolded system is commonly used in facial-tissue stacks, and it is because of the interfolded system that a user can pull one facial tissue at a time from a facial-tissue box. The interfolded system is also used in a variety of paper-towel stacks that are used in paper-towal dispensing devices commonly found commercial restrooms.
A known short coming of using the interfolded system to stack dispenser napkins 10 having tab portions 80 is that all of the dispenser-napkin tab portions 80 within the stack are arranged on the same side of the stack as shown in
Four-panel dispenser napkins are well known. To make a four-panel napkin, a napkin is first folded in one direction and then folded again in another.
It is well known that most dispenser napkins are embossed with various patterns. Embossing not only enhances the aesthetics of the napkin, it also creates: i) more surface area and ii) volume. Embossing creates some surface roughness, which can vary depending on the strength of the embossing pattern, but unlike facial tissues where silkiness of the surface is important to the consumers, some level of roughness is generally desired for paper-napkin applications.
To emboss a pattern, a paper-napkin sheet is passed through rollers with metal engraving. After exiting the embossing section, the paper napkin is embossed. An embossed napkin has a male side of the emboss and a female side of the emboss. The male side of the emboss has a protruding pattern that results in surface roughness. The female side of the emboss, on the other hand, has cavities and its surface is relatively softer than the male side of the emboss.
A shortcoming in the prior art is that four-panel embossed dispenser napkins are commonly arranged using the interfolded system in such a manner that the male side of the emboss of a napkin within the stack is in contact with an adjacent napkin's male side of the emboss. This male-to-male arrangement results in an amount of friction that commonly causes a dispenser napkin to tear when it is being pulled from a napkin dispenser.
A need remains for an improved dispenser-napkin stacking arrangement.
A stacked dispenser-napkin composition having a plurality of stacked and interfolded dispenser napkins; each dispenser napkin being embossed and having a male side of the emboss and a female side of the emboss; each dispenser napkin having a first, second, third, and fourth panel, the four panels being defined by a first fold and a second fold; each dispenser napkin's first and second panels being adjacent to each other and having respective areas that are substantially equal; each dispenser napkin's third and fourth panels being adjacent to each other and having respective areas that are substantially equal; the combined areas of each dispenser napkin's first and second panels being greater than the combined areas of the dispenser napkin's third and fourth panels; each dispenser napkin having a tab portion, the tab portion being the portions of the first and second panel areas that are not covered by the third and fourth panel areas when the first and second panels are folded onto the third and fourth panels via the first fold; the plurality of stacked and interfolded dispenser napkins being arranged within the stack such that the positions of the respective tab portions on adjacent dispenser napkins alternate between two opposing sides of the stack; and the plurality of stacked and interfolded dispenser napkins being arranged within the stack such that the position of a stacked dispenser napkin's male side of its emboss is in contact with an adjacent dispenser napkin's female side of its emboss.

A stacked dispenser-napkin composition having a plurality of stacked and interfolded dispenser napkins; each dispenser napkin being embossed and having a male side of the emboss and a female side of the emboss; each dispenser napkin having a first, second, third, and fourth panel, the four panels being defined by a first fold and a second fold; each dispenser napkin's first and second panels being adjacent to each other and having respective areas that are substantially equal; each dispenser napkin's third and fourth panels being adjacent to each other and having respective areas that are substantially equal; the combined areas of each dispenser napkin's first and second panels being greater than the combined areas of the dispenser napkin's third and fourth panels; each dispenser napkin having a tab portion, the tab portion being the portions of the first and second panel areas that are not covered by the third and fourth panel areas when the first and second panels are folded onto the third and fourth panels via the first fold; the plurality of stacked and interfolded dispenser napkins being arranged within the stack such that the positions of the respective tab portions on adjacent dispenser napkins alternate between two opposing sides of the stack; and the plurality of stacked and interfolded dispenser napkins being arranged within the stack such that the position of a stacked dispenser napkin's female side of its emboss is in contact with an adjacent dispenser napkin's female side of its emboss.
A commercial advantage of stacked-dispenser napkin embodiments is that because the tab portions 80 of adjacent dispenser napkins 10 alternate from one side to the other, as shown in
An additional advantage of the embodiments is that because the male side of the emboss of a first napkin is in contact with the female side of the emboss of adjacent dispenser napkins within a stack, or vice versa, dispenser napkins are less likely to rip when pulled from a dispensing apparatus; this is because of the reduced friction between the embodiment's male-to-female-side-of-the-emboss arrangement of adjacent dispenser napkins compared to known male-to-male-side-of-the-emboss arrangement of adjacent dispenser napkins. The embodiment's male-to-female-side-of-the-emboss arrangement within the stack results in fewer dispenser napkins being torn or bunched together during dispensing compared to the number of dispenser napkins that are torn or bunched together during dispensing from known dispensing-napkin stacking arrangements.
Another advantage provided by dispenser-napkin stack embodiments is that the efficient dispensing of napkins is achieved when one or more of the stack embodiments is used in a paper-napkin-dispensing apparatus that is engineered to provide a user with one paper napkin per pull instead of many paper dispenser napkins per pull. Furthermore, using one or more of the stack embodiments with a paper-napkin-dispensing apparatus results in dispensing a paper napkin with each pull, wherein the dispensed napkin is not damaged or ripped because of the friction resulting from the pulling action.
Generally shown are embodiments directed to a stacked dispenser-napkin composition, wherein the dispenser napkins 10 are stacked according to the interfolded system 20 shown in
