Description




FIELD OF THE INVENTION




This invention generally relates the field of dispensing devices and systems. More particularly, this invention relates to the field of devices and systems for dispensing folded sheets of material.




BACKGROUND




Dispensers for paper napkins are often provided at quick service food locations. One disadvantage of many conventional paper napkin dispensers is that they often permit removal of large clumps of napkins at one time. Studies have shown most paper napkins removed in this manner are wasted. Many end up scattered about an eating area, tossed as litter or, even worse, being stuffed in plumbing fixtures. When clumps of napkins are taken, dispensers quickly run out and must be refilled inconveniencing both customers and operators of quick service food locations.




A long and unfilled need exists for a paper napkin dispensing system that will deter and resist wasteful dispensing.




SUMMARY OF THE INVENTION




The problems and needs described above are addressed by the present invention which provides an interfolded paper napkin dispensing system composed of: (a) an outer housing defining an interior space; (b) stacking means mounted within the outer housing for holding a stack of paper napkins within the interior space; and (c) a dispensing face defined in the outer housing proximate to an end of the stacking means.




The dispensing face has a central portion projecting out from the dispenser and a dispensing throat located in the central portion. The dispensing throat is composed of a slot portion having a length sufficient to permit a paper napkin to be pulled through by a user, but a relatively narrow width that prevents more than a few napkins from being pulled through the throat at one time. The dispensing throat further includes a finger access portion to help a user grip and pull a paper napkin through the dispensing slot despite the relatively narrow width of the dispensing slot.




According to the invention, the stacking means are composed of a staging area proximate the dispensing throat for spacing, bowing and slowing napkins as they approach the dispensing throat. The staging area may be composed of at least two curved bumpers oriented so as to be parallel to the path of travel of the napkins as they approach the dispensing throat, and a number of ribs defined on the bumpers for temporarily arresting movement of the napkins as they approach the dispensing throat. Desirably, the staging area and bumpers are configured to cause the napkins to bow out into the dispensing throat.




In an aspect of the invention, the slot portion of the dispensing throat may have a point of minimum width that is less than about 1.0 inch. For example, the slot portion of the dispensing throat may have a point of minimum width that is less than about 0.75 inches. As another example, the slot portion of the dispensing throat may have a point of minimum width that is less than about 0.5 inches.




According to the invention, the finger access portion of the dispensing throat may have a point of maximum width that is greater than about 0.75 inches. For example, the finger access portion of the dispensing throat may have a point of maximum width that is greater than about 1 inch. Desirably, the finger access portion of the dispensing throat is at the center of the dispensing throat and may have a length (i.e., a length along the dispensing throat) of about 1 inch or more. For example, the finger access portion of the dispensing throat may have a length from about 1 inch to about 3 inches or more. Typically, the finger access portion of the dispensing throat may have a length that is about one-half the length of the dispensing throat. Of coarse, it is contemplated that the finger access portion of the dispensing throat may have a length that is about one-quarter to about three-quarter the length of the dispensing throat.




According to the present invention, the central portion of the dispensing face may project out from the dispenser in the form of a first surface and a second surface joined at an obtuse angle. In such an embodiment, the dispensing throat should be located at about the intersection of the first and second surfaces. Other configurations of the dispensing face which provide a crease or break in the plane of the dispensing face at the dispensing throat may also be used.




These and various other advantages and features of novelty which characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying description of the invention.

DETAILED DESCRIPTION




Referring now to the drawings, wherein like reference numerals designate corresponding structure throughout the views, and referring in particular to

FIGS. 1 and 2

, there is shown an exemplary interfolded paper napkin dispensing system. The system includes an outer housing


12


defining an interior space


14


that contains a stacking means


16


which is mounted within the outer housing


12


for holding a stack of paper napkins


18


within the interior space.




The system also includes a dispensing face


20


defined in the outer housing


12


proximate to an end of the stacking means


16


.




The dispensing face


20


has a central portion


22


projecting out from the outer housing


12


and a dispensing throat


24


located in the central portion


22


. The dispensing throat


24


is composed of a slot portion


26


having a length sufficient to permit a paper napkin to he pulled through by a user, but a relatively narrow width that prevents more than a few napkins from being pulled through the throat at one time.




The dispensing throat


24


further includes a finger access portion


28


to help a user grip and pull an interfolded paper napkin through the dispensing slot despite the relatively narrow width of the dispensing slot


26


.




Referring now to

FIG. 3

, the stacking means


16


are composed of a staging area


30


proximate the dispensing throat


24


for spacing and slowing napkins as they approach the dispensing throat. The staging area


30


may be composed of at least two bumpers


32


oriented so as to be parallel to the path of travel of the napkins as they approach the dispensing throat, and a number of ribs


34


defined on the bumpers


32


for temporarily arresting movement of the napkins as they approach the dispensing throat.




The bumpers


32


, in combination with a spring loaded plate


36


that pushes against the stack of napkins


18


, cause the interfolded napkins to bow out or buckle into the dispensing throat


24


. Such a configuration is believed to aid dispensing of the napkins by causing the napkins to feed into the dispensing throat


24


relatively uniformly and relatively independent of how full the dispenser is during dispensing. The bumpers also center the napkins on the dispensing throat to reduce the likelihood that napkins will drag against an end of the dispensing slot creating friction that may tear a napkin and interrupt dispensing. The bow or buckle in the napkins is thought to enhance the contact/friction between interfolded sheets of the paper napkin for more reliable dispensing.




Referring now to

FIG. 4

, there is shown a detail of the dispensing throat


24


which reveals a configuration to prevent large clumps of paper napkins from being pulled out of the dispenser at one time. Specifically, the dispensing throat


24


has a slot portion


26


that has a length sufficient to permit a paper napkin to be pulled through by a user, but a relatively narrow width that will prevent more than a few paper napkins from being pulled through the throat at one time. The dispensing throat


24


includes a finger access portion


28


to help a user grip and pull a paper napkin through the dispensing slot


26


despite the relatively narrow width of the slot.




The slot portion


26


of the dispensing throat


24


may have a point of minimum width “W” that is less than about 1.0 inch. For example, the slot portion “W” of the dispensing throat may have a point of minimum width that is less than about 0.75 inches. As another example, the slot portion “W” of the dispensing throat may have a point of minimum width that is less than about 0.5 inches.




The finger access portion


28


of the dispensing throat may have a point of maximum width “F” that is greater than about 0.75 inches. For example, the finger access portion of the dispensing throat may have a point of maximum width “F” that is greater than about 1 inch.




Desirably, the finger access portion


28


of the dispensing throat


24


is at the center of the dispensing throat and may have a length “L” (i.e., a length along the dispensing throat) of about 1 inch or more. For example, the finger access portion of the dispensing throat may have a length “L” from about 1 inch to about 3 inches or more. Typically, the finger access portion of the dispensing throat may have a length “L” that is about one-half the total length “T” of the dispensing throat. Of coarse, it is contemplated that the finger access portion of the dispensing throat may have a length “L” that is about one-quarter to about three-quarter the total length “T” of the dispensing throat.




Referring now to

FIG. 5

, it can be seen that the central portion


22


of the dispensing face


20


projects out from the outer housing


12


of the dispenser. In an embodiment of the invention, the central portion


22


of the dispensing face


20


projects out in the form of a first surface


40


and a second surface


42


joined at an obtuse angle α (i.e., greater than 90 and less than 180 degrees). The dispensing throat


24


should be located at about the intersection


44


of the first and second surfaces


40


,


42


where there is a crease or break in the plane of the dispensing face


20


. Such configuration is thought to provide better access to the paper napkins through the relatively narrow dispensing slot


26


. It is contemplates that other configurations of the dispensing face which provide a suitable crease or break in the plane of the dispensing face at the dispensing throat may be used.




Generally speaking, the angle α may range from about 175 degrees to about 160 degrees to provide a crease or break in the plane of the dispensing face


20


. For example, the angle α may range from about 173 degrees to about 162 degrees. As another example, the angle α may range from about 170 degrees to about 165 degrees.




During normal operation, a consumer will grasp the interfolded paper napkin by grabbing the portion or tail of the interfolded napkin protruding/extending through the dispensing slot. As the interfolded napkin is dispensed, another portion of the succeeding napkin is withdrawn to provide the next outwardly extending protruding portion/tail of the napkin. If the consumer encounters a new stack of interfolded napkins in which the tail does not protrude through the dispensing slot


26


or if the previous dispensing failed to properly draw a new tail through the slot, the user will grasp the exposed portion of the paper napkin and pinch the body of the napkin by placing one or more fingers in the finger access portion


28


of the dispensing throat


24


. If the user pulls too aggressively, such as in an attempt to pull a large clump of paper napkins out of the dispenser, the attempt will be thwarted because a large clump of napkins will not fit through the dispensing slot


26


. Accordingly, wasteful dispensing of the paper napkins is reduced.




The present invention had been found to be particularly desirable for use with horizontally placed interfolded paper napkin dispensers. The combination of a narrow dispensing throat, projecting dispensing face, stacking means and bumpers that bow out the napkins in a staging area provide reliable and less wasteful dispensing of interfolded paper napkins.




It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
