Abstract
The device for dispensing paper towels has a housing for holding a generally vertical stack of the paper towels and including a lower portion through which individual towels can be dispensed. The lower portion includes an elongated opening through which a fold of the bottommost towel can extend and be accessible for a user to grab and pull the bottommost towel from the stack. Improved towel dispensing is enabled by laterally spaced and upwardly-directed ramps located in the vicinity of the front edge of the opening and upon which an edge of the stack rests, opposed end pads angled downwardly to the opening and upon which the stack ends rest, and/or a bottom cabinet portion angled with respect to the rest of the cabinet to transfer stack weight. The opening preferably is shaped to cause the fold of the bottommost towel to assume a C-shape.
Description




The device for dispensing multi-fold paper towels provided by the invention includes a housing for holding a generally vertical stack of the paper towels and a lower portion through which individual towels are dispensed from the stack. The lower portion preferably includes a front wall, rear wall, opposed side walls and a bottom wall. The paper towels are dispensed through an elongated opening in the bottom wall through which a fold of the bottommost towel in the stack can extend and be disposed in a position where a user can grab the fold and pull the bottommost towel from the stack. The present invention provides one or more elements for improved towel dispensing. Specifically, the device can include a plurality of laterally spaced ramps or ribs located in the vicinity of one edge of the opening. These ribs have an inclined surface extending upwardly and preferably at an angle from that edge and are adapted to be engaged by and support one side portion of the towels with the other side portion supported adjacent to an opposite wall of the bottom portion. These ribs transfer a portion of the pressure applied on the bottommost towel from the side portion supported on the ribs toward the other side portion, thereby reducing the force required to pull the bottommost towel from the stack. The present invention can also or instead employ ribs arranged at a varying angle along the stack of towels. Some preferred embodiments of the present invention employ pads located on either end of the opening to transfer a portion of the pressure applied on the bottommost towel from the end portions supported on the pads toward the opening, thereby reducing the force required to pull the bottommost towel from the stack. The lower portion of the device or internal walls therein can also or instead be angled, bent, curved, or otherwise misaligned with respect to the remainder of the device in order to shift the stack weight to the rear of the cabinet, thereby resulting in desirable force distribution for towel dispense. The various embodiments of the present invention employ one or more of the above-described features and elements for significantly improved product dispensing characteristics.




In some highly preferred embodiments of the present invention, further advantages result from one edge of the opening preferably being generally U-shaped and the other edge preferably being configured to cause the fold of the towel extending through the opening to assume a C-like shape.

DESCRIPTION OF PREFERRED EMBODIMENTS





FIGS. 1-6

illustrate a dispenser


10


for multi-fold paper towels incorporating various features of the invention. The dispenser


10


includes a housing or cabinet


12


having an internal chamber


14


for holding a generally vertically oriented stack


16


of elongated, generally rectangular multi-fold paper towels


18


having opposed side portions


20


and


22


and opposed end portions


24


. The multi-fold paper towels


18


can be Z-fold paper towels in which succeeding towels are interfolded, C-fold paper towels in which succeeding towels are merely stacked, or any other suitable type of towel folded and/or interfolded in any conventional manner. The cabinet


12


preferably has a pivotally mounted front door


28


which can be swung down to gain access to the chamber


14


and a lower portion


30


from which individual paper towels can be dispensed from the stack. In alternate embodiments, the cabinet


12


may be formed without a front door


28


. For example, access to the interior of the cabinet


12


(e.g., for placing new towels therein) can be through an open cabinet top, in which case the cabinet


12


acts much like a chute within which-stacked towels are retained prior to dispense. As another example, the cabinet


12


can have a side door or a top door hinged, detachable, or otherwise movable in any conventional manner for access to the interior of the cabinet


12


.




As best illustrated in

FIG. 2

, the lower portion


30


of the cabinet


12


preferably includes a front wall


32


, a rear wall


34


, opposed side walls


36


and a bottom wall


40


. The bottom wall


40


has a front portion


42


, a rear portion


44


and opposed side pads


46


. Each opposed side pad


46


is preferably triangular in shape when viewed from above, with the base of the triangle coincident with an opposed side wall


36


, and the apex of the triangle meeting the opening


52


adjacent to opposed end edge


58


. Each opposed side pad


46


preferably slopes downwardly from its base to its apex.




Located in the bottom wall


40


is an elongated dispenser opening


52


, having a length and width smaller than that of the paper towels


18


, through which a fold


50


of the bottommost towel extends and is ready for a user to grab and pull the bottommost towel from the stack


16


. The dispensing opening


52


has a front side edge


54


, a rear side edge


56


and opposed end edges


58


spaced inwardly from respective side walls


36


of the lower portion


30


. The front edge


54


preferably has a generally U-shape as illustrated in

FIG. 2

for reasons explained in more detail below. Although the dispenser opening


52


is located in a rear portion of the bottom wall


40


in the illustrated preferred embodiment, it should be noted that the dispenser opening


52


can be in a more forward location if desired (preferably subject to the other features and elements of the present invention described in more detail below).




In accordance with the invention, the lower portion


30


of the cabinet


12


is arranged to reduce the force required for a user to pull the bottommost towel


18


from the stack


16


and yet permit the stack


16


to apply sufficient pressure on the next towel to prevent it from being pulled from the stack


16


along with the bottommost towel. In the specific embodiment illustrated, this is preferably accomplished in part by at least one of two methods.




First, pressure is reduced by providing one or more structural elements located in front of the front edge


54


of the opening


52


and extending upwardly from the front portion


42


of the bottom wall


40


. This structure performs the function of transferring weight of the stack


16


from the front of the lower portion


30


of the cabinet


12


to the rear of the lower portion


30


of the cabinet, and preferably does so by elevating the front of the towels in the stack


16


with respect to the rear of these towels. Although the front of all towels in a stack


16


are preferably oriented in this manner as shown in

FIGS. 1-6

, similar results can be obtained by orienting at least the bottommost towels in this manner.




A number of different elements and structure can be used to perform the function just described. However, excellent results are obtained by employing a plurality of laterally spaced ribs or ramps


60


,


62


,


64


,


66


located (as described above) in front of the front edge


54


of the opening


52


and extending upwardly from the front portion


42


of the bottom wall


40


. Where such spaced ribs or ramps


60


,


62


,


64


,


66


are employed, the inclined surfaces of these elements can be inclined toward or away from the front portion


42


of the bottom wall


40


(see ramps


60


,


62


,


64


,


66


in the embodiment shown in

FIGS. 1-6

and ramps


160


,


162


,


164


in the embodiment shown in FIGS.


7


-


10


). In less preferred embodiments, the ribs can even be substantially vertical while still performing the same functions described above.




Referring again to the highly preferred embodiment of

FIGS. 1-6

, each of these ramps has an inclined surface


68


extending in a direction upwardly and away from the front edge


54


of the opening


52


. That is, as viewed in

FIGS. 3-5

, the inclined surfaces


68


extend toward the front wall


32


at an acute angle relative to a horizontal plane


70


extending through the front edge


54


of the opening


52


.




The front wall


32


, the ribs


60


,


62


,


64


,


66


(or other similar structure) and the front portion


42


are preferably integrally formed as shown in

FIGS. 1-6

. However, in alternative embodiments, the ribs


60


,


62


,


64


,


66


can be integrally formed with just the front portion


42


or with just the front wall


32


as desired. Alternatively, the ribs


60


,


62


,


64


,


66


can be separate elements attached to either or both of the front portion


42


and the front wall


32


in any conventional manner.




One side portion


20


of the bottommost towel


18


is supported on the inclined surfaces


68


of the ramps and the other side portion


22


rests on the rear portion


44


of the bottom wall


40


adjacent the rear wall


34


. The ramps effectively transfer a portion of the pressure applied on the bottommost towel from the front side portion


20


to the rear side portion


22


, thereby reducing the force required for a user to pull the bottommost towel


18


from the stack


16


.




Although a plurality of spaced apart ribs or ramps


60


,


62


,


64


,


66


are preferred for performing the pressure-transferring function described above, other elements can instead be used as desired. For example, the ribs or ramps


60


,


62


,


64


,


66


can be replaced by one or more rotatable rollers upon an axle mounted in any conventional manner in front of the front edge


54


of the opening


52


, by a plurality of posts, bosses, fingers, or other elements extending from the front portion


42


and/or front wall


32


, by a bar, rod, tube, shaft, or other elongated element extending in front of the front edge


54


of the opening


52


across the interior of the cabinet


12


, or even by a wall of the cabinet


12


that is shaped to project toward the stack


16


(e.g., the front wall


32


or the front portion


42


inwardly bent, angled, stepped, curved, bowed, or otherwise shaped to support or hold a stack in the same manner as the ribs or ramps


60


,


62


,


64


,


66


described above). Each of these alternative elements and structures performs the same or similar functions to the ribs or ramps


60


,


62


,


64


,


66


, and falls within the spirit and scope of the present invention.




In some highly preferred embodiments of the present invention, the ramps


60


,


62


,


64


,


66


(or alternative structures or elements as described above) are arranged to also transfer the pressure applied on the bottommost towel in a direction away from the center. Stated differently, the ramps


60


,


62


,


64


,


66


impart curvature in the stack of towels between side portions


20


and


22


to relieve the stack weight pressure in the direction from side portion


20


to side portion


22


. This is accomplished by progressively decreasing the acute angle of the inclined surfaces


68


in a direction away from the centrally located ramp


60


. For example, in the specific embodiment illustrated in

FIG. 3

, the angle A of the inclined surfaces for the center ramp


60


and the two adjacent ramps


62


are the same and can be about 76.5°, the angle B of the inclined surfaces


68


for the ramps


64


are the same and can be about 75° and the angle C of the inclined surfaces


68


for the ramps


66


are the same and can be about 69.5°. The inclined surfaces


68


cause the side portion


20


of the towels


18


and the stack to assume an arcuate shape, i.e. a generally concave shape like that illustrated by the dashed line in FIG.


2


.




Although the steepness of the ramps


60


,


62


,


64


,


66


in the illustrated preferred embodiment gradually decreases with increased lateral distance away from the center of the cabinet


12


, it should be noted that this feature of the present invention can be practiced by having as few as two surfaces defined by two ramps or other elements or structure (described above) in which the surface closest to the center of the cabinet


12


has a steeper angle than the surface farther away from the center of the cabinet


12


. For example, where the front


20


of the stack


16


is supported on a surface of an inwardly-projecting front wall


32


(rather than upon ribs), the front wall


32


can be steeper near the center of the stack


16


than at the ends


24


of the stack


16


to produce the same stack shape as the differently-angled ribs


60


,


62


,


64


,


66


described above. Similarly, any of the elements and structures referred to earlier as alternatives to ribs


60


,


62


,


64


,


66


can be shaped in such a manner and fall within the spirit and scope of the present invention.




Most preferably, the ribs


60


,


62


,


64


,


66


have varying steepnesses as described above. However, the ribs


60


,


62


,


64


,


66


(or alternative elements and structure thereto) in less preferred embodiments can present the same angle to the stack


16


across the length of the stack


16


, if desired. In other words, the ribs


60


,


62


,


64


,


66


can each have generally the same angle.




A second method used to reduce the force required for a user to pull the bottommost towel


18


from the stack


16


and yet permit the stack


16


to apply sufficient pressure on the next towel to prevent it from being pulled from the stack


16


along with the bottommost towel employs the opposed side pads


46


. Stated differently, the pads


46


impart curvature in the stack of towels between opposed end portions


24


to relieve the stack weight pressure in the direction between the end portions


24


. In the illustrated preferred embodiment of

FIGS. 1-6

, the pads


46


are triangular in shape, and slope downwardly toward the opening


52


. The downward slope of the triangular shape of each opposed side pad


46


transfers the pressure applied on the bottommost towel in a direction away from opposed end portions


24


of the towel and toward the opening


52


. The inclined opposed side pads


46


cause the opposed end portions


24


of the towels


18


and the stack to assume an arcuate shape, i.e., a generally upwardly-directed concave shape. The opposed side pads


46


prevent a towel


18


from hanging up when being pulled from the stack


16


. Although triangular side pads


46


are preferred, the side pads


46


can take virtually any shape desired, including without limitation square, rectangular, round, oval, and the like. As with triangular side pads


46


, these other pads act to funnel the opposed end portions


24


of the towels


18


toward the opening


52


.




In addition to or instead of employing a wall structure to define the pads


46


as illustrated in

FIGS. 1-6

, one or more projections can extend from the bottom wall


40


and/or side walls


36


of the cabinet


12


, upon which the end portions


24


of the stack


16


rest in a manner similar to that just described with reference to the pads


46


. These projections can be in the form of spaced ribs or ramps such as those at the front of the cabinet, or can take any of the alternative forms of such ribs or ramps described above.




A third method used to reduce the force required for a user to pull the bottommost towel


18


from the stack


16


and yet permit the stack


16


to apply sufficient pressure on the next towel to prevent it from being pulled from the stack


16


along with the bottommost towel employs the shape of the bottom portion


30


. This method is described in detail below with respect to the embodiment of the present invention shown in

FIGS. 7-10

, but can be also applied to the first preferred embodiment.




In operation, a user pulls the exposed towel from the opening


52


. Because the folds of the towels are preferably intertwined, the flap or fold of the next towel to be distributed is pulled down through the opening


52


. Because of the curvature imparted to the stack of towels by both the ramps


60


,


62


,


64


,


66


, and the pads


46


, the fibers of the flap of the paper towel are preferably actually broken, causing the flap of the next towel to be distributed to retain a C-like shape. Moreover, the opening


52


is arranged to cause the flap


50


of the towel


18


next to the bottommost one to be “puffed”, i.e. formed into a C-like shape as illustrated in

FIGS. 1 and 2

, as the bottommost towel is pulled from the stack. This encourages a user to grab the center of the flap


50


and pull from the center of the stack where the least pressure is applied. In the specific embodiment illustrated, this is accomplished by arranging the front edge


54


of the opening


52


to have a generally U-shape and providing the rear edge


56


of the opening


52


with opposite end portions


72


and


74


connected to the rear edge


56


and extending at an angle outwardly toward the opposite end edges


58


and in the direction of a respective side wall


36


.





FIGS. 7-10

illustrate an alternate embodiment of the dispenser


10


described above. As best illustrated in

FIGS. 9 and 10

, a dispenser


110


for folded paper towels incorporates various features of the invention. The dispenser


110


includes a housing or cabinet


112


having an internal chamber


114


for holding a generally vertically oriented stack


116


of elongated, generally rectangular folded paper towels


118


having opposed side portions


120


and


122


and opposed end portions


124


. The paper towels


118


are preferably multi-folded, and can be Z-folded paper towels in which succeeding towels are interfolded, C-folded paper towels in which succeeding towels are merely stacked, or any other towels folded or interfolded in any conventional manner. The cabinet


112


preferably has a pivotally mounted front door


128


which can be swung down to gain access to the chamber


114


and a lower portion


130


from which individual paper towels


118


can be dispensed from the stack


116


.




As best illustrated in

FIGS. 8 and 10

, the lower portion


130


of the cabinet


112


preferably includes a front wall


132


, a rear wall


134


, opposed side walls


136


and a bottom wall


140


. The bottom wall


140


has a front portion


142


, a rear portion


144


and opposed side pads


146


. Each opposed side pad


146


is preferably triangular in shape when viewed from above, with the base of the triangle coincident with an opposed side wall


136


, and the apex of the triangle meeting the opening


152


adjacent to opposed end edge


158


. Each opposed side pad


146


slopes downwardly from its base to its apex. In alternative embodiments, the side pads


146


can take any shape as described above with reference to the first preferred embodiment of the present invention, and can also or instead include any number of inwardly-projecting surfaces for supporting the stack ends


124


as also described above. The opposed side pads


146


and such inwardly-projecting surfaces (if used) perform the same functions as those of the first preferred embodiment above.




Located in the bottom wall


140


is an elongated dispenser opening


152


, having a length and width smaller than that of the paper towels


118


, through which a fold


150


of the bottommost towel extends and is ready for a user to grab and pull the bottommost towel from the stack


116


. The elongated dispenser opening


152


can be located differently in the bottom wall


140


as described above with reference to the first preferred embodiment. The dispensing opening


152


has a front side edge


154


, a rear side edge


156


and opposed end edges


158


spaced inwardly from respective of the side wall


136


. The front edge


154


preferably has a generally U-shape as illustrated in

FIG. 7

for reasons explained in more detail below.




In accordance with the invention, the lower portion


130


of the cabinet


112


is arranged to reduce the force required for a user to pull the bottommost towel


118


from the stack


116


and yet permit the stack


116


to apply sufficient pressure on the next towel to prevent it from being pulled from the stack


116


along with the bottommost towel. In the specific embodiment illustrated, this is preferably accomplished in part by at least one of three methods.




First, pressure is reduced by providing a plurality of laterally spaced ribs or ramps


160


,


162


,


164


(see

FIG. 8

) located on the front wall


132


adjacent the front edge


154


of the opening


152


and extending outwardly from the curved front wall


132


(see FIG.


10


). Each of these ramps has an inclined surface


168


extending in a generally upward direction. The ramps


160


,


162


,


164


, their function, and alternative devices and structures to the ramps


160


,


162


,


164


are similar to those of the first preferred embodiment described above, with the exception that the ramps


160


,


162


,


164


(or alternative devices and structures) are preferably located on the back side of the door


128


as shown in

FIGS. 8 and 10

.




One side portion


120


of the bottommost towel


118


is supported on the inclined surfaces


168


of the ramps


160


,


162


,


164


and the other side portion


122


rests on the rear portion


144


of the bottom wall


140


adjacent the rear wall


134


(see FIG.


10


). The ramps effectively transfer a portion of the pressure applied on the bottommost towel from the side portion


120


to the other side portion


122


, thereby reducing the force required for a user to pull the bottommost towel


118


from the stack


116


.




Like the ramps


60


,


62


,


64


,


66


of the first preferred embodiment, the ramps


160


,


162


,


164


(or alternative structures and device thereto) can have a varying or constant steepness along the length of the stack


116


.




A second method used to reduce the force required for a user to pull the bottommost towel


118


from the stack


116


and yet permit the stack


116


to apply sufficient pressure on the next towel to prevent it from being pulled from the stack


116


along with the bottommost towel employs opposed side pads


146


(see FIG.


8


). Stated differently, the pads


146


impart curvature in the stack of towels between opposed end portions


124


to relieve the stack weight pressure in the direction between the end portions


124


. The downward slope of each opposed side pad


146


, as illustrated in

FIG. 8

, transfers the pressure applied on the bottommost towel in a direction away from opposed end portions


124


of the towel and toward the opening


152


. The inclined opposed side pads


146


cause the opposed end portions


124


of the towels


118


and the stack to assume an arcuate shape, i.e., a generally upwardly-directed concave shape. The opposed side pads


146


prevent a towel


118


from hanging up when being pulled from the stack


116


. As stated above, in alternate embodiments, the side pads


146


can be of any shape desired, and preferably are triangularly shaped as illustrated in FIG.


8


. Additional information regarding the side pads


146


, their function, and alternatives thereto can be found in the description of the first preferred embodiment above.




A third method used to reduce the force required for a user to pull the bottommost towel


118


from the stack


116


and yet permit the stack


116


to apply sufficient pressure on the next towel to prevent it from being pulled from the stack


116


along with the bottommost towel employs a unique shape of the bottom portion


130


of the cabinet


112


. As illustrated in

FIGS. 9 and 10

, the bottom portion


130


of the cabinet


112


is angled away from the remainder of the cabinet


112


(which is generally vertical). As a result, a majority of the weight of stack


116


is directed away from the bottommost of the towels


118


and toward the curved rear wall


134


. Stated differently, the outward angle of the bottom portion


130


transfers the pressure applied on the bottommost towel in a direction away from the side portion


120


to and beyond the other side portion


122


, thereby reducing the force required for a user to pull the bottommost towel


118


from the stack


116


. The outward angle of the bottom portion


130


can be defined by curved cabinet walls


132


,


134


,


136


as shown in

FIGS. 7-10

or can be defined by cabinet walls


132


,


134


,


136


that have multiple portions angled with respect to one another to orient the bottom portion


130


at an angle with respect to the remainder of the cabinet


112


.




The use of a bottom portion


130


outwardly angled with respect to the remainder of the cabinet


112


is a preferred feature of the present invention that can be used alone or in conjunction with the other features and elements of the present invention described above, such as with ramps


160


,


162


,


164


, with opposed side pads


146


, and the like.




In an example of operation, a user pulls the exposed towel from the opening


152


. Because the folds of the towels are intertwined in the case of interfolded towels (e.g., Z-interfolded towels), the flap or fold of the next towel to be distributed is pulled down through the opening


152


. Because of the curvature imparted to the stack of towels by both the ramps


160


,


162


, and


164


, and the pads


146


, the fibers of the flap of the paper towel are preferably actually broken, causing the flap of the next towel to be distributed to retain a C-like shape. Moreover, the opening


152


is preferably arranged to cause the flap


150


of the towel


118


next to the bottommost one to be “puffed”, i.e. formed into a C-like shape generally shown in

FIG. 7

, as the bottommost towel is pulled from the stack. This encourages a user to grab the center of the flap


150


and pull from the center of the stack where the least pressure is applied. In the specific embodiment illustrated, this is accomplished by arranging the front edge


154


of the opening


152


to have a generally U-shape and providing the rear edge


156


of the opening


152


with opposite end portions


172


and


174


connected to the rear edge


156


and extending at an angle outwardly toward the opposite end edges


158


and in the direction of a respective side wall


136


.




The embodiments described above and illustrated in the figures are presented by way of example only and are not intended as a limitation upon the concepts and principles of the present invention. As such, it will be appreciated by one having ordinary skill in the art that various changes in the elements and their configuration and arrangement are possible without departing from the spirit and scope of the present invention as set forth in the appended claims. For example, in both illustrated preferred embodiments of the present invention, the front portion


20


,


120


of the stack


16


,


116


is located upon or against ribs


60


,


62


,


64


,


66


,


160


,


162


,


164


while the rear portion


22


,


122


of the stack


16


,


116


is located upon or against a rear portion


44


,


144


of the bottom wall


40


,


140


. In alternative embodiments, the ribs or other alternative devices or structures thereto can be located at a rear portion of the cabinet


12


,


112


while the stack


16


,


116


can be supported against a surface of the bottom wall


40


,


140


located at the front of the cabinet


12


,


112


. Such a bottom portion arrangement is essentially the opposite of that illustrated in the figures, but would perform similar functions to those described above. Similarly, less preferred embodiments of the present invention can have bottom portions


130


angled rearwardly rather than forwardly as described above and illustrated in

FIGS. 7-10

.
