Abstract
A dispensing system for individual folded webs having an area of non-uniform thickness across the length of the web is composed of several components. An outer housing defines an interior space in which stacking means for holding a stack of individual folded webs are mounted. A dispensing face is 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 in the form of a first surface and a second surface joined at an obtuse angle and a dispensing throat located in the central portion at about the intersection of the first and second surfaces. The dispensing system also includes a stack of individual folded webs having an area of non-uniform thickness across the length of the web aligned so that an area of greatest thickness extends across the width of the dispensing throat. At least one recessed section along at least one edge of the dispensing throat contacts the stack of individual folded webs so that a portion of the stack of individual folded webs projects outward from the dispensing throat.
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 individual folded webs such as paper napkins are often provided at quick service food locations. One disadvantage of many conventional paper napkin dispensers is that they often provide rather poor one-at-a-time dispensing of folded napkins. Such inadequate one-at-a-time dispensing can be particularly noticeable if the napkins are individual folded napkins (e.g., conventional overfold napkins) instead of interfolded napkins. Another disadvantage is that many conventional overfold napkin dispensers 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 conventional overfold paper napkin
10
typically has a closed end
12
that is defined by a main panel
14
of absorbent paper material and an open end
16
that is defined by second panel
18
. An optional third panel
20
may be folded under the second panel
18
. The second and third panels
18
,
20
are unitary with main panel
14
, and are, respectively, connected to main panel
14
at fold lines that are at opposite ends of main panel
14
, as may be seen in
FIG. 1. A
conventional paper napkin may be made of a single ply or a multiple ply material. For example,
FIG. 1
shows a two ply material having a first ply
22
and a second ply
24
.
One common problem with conventional overfold paper napkins may be seen in reference to
FIGS. 2A and 2B
. Conventional overfold paper napkins are designed to be stacked in a napkin dispenser
26
such as, for example, a spring loaded napkin dispenser or a gravity feed dispenser. Such napkin dispensers have an opening
28
so that the open end
16
of the napkin
10
faces the opening
28
as shown in FIG.
2
A. In this position, a user can grab the second panel
18
to pull the napkin
10
out of the dispenser
26
. However, when stacked improperly, as shown in
FIG. 2B
, with the closed end
12
facing the opening
28
, dispensing is awkward, and often results in wastage. Not uncommonly, maintenance personnel will stack overfold paper napkins improperly, as shown in
FIG. 2B
rather than as shown in FIG.
2
A.
Moreover, conventional overfold paper napkins are two to three times as thick where the second panel
18
and the optional third panel
20
are folded over the main panel
14
. When such paper napkins are arranged in a stack, the stack will have its greatest thickness across an upper or lower edge
30
of the opening
28
in the dispenser
26
as seen in FIG.
3
. Pressure generated by a spring-loaded dispenser or an overfilled dispenser will force the thickest portion of the stack against the edge
30
of the dispenser
26
. If sufficient pressure exists, friction between the edge
30
of the dispenser
26
and the outermost paper napkin will make it difficult to remove a napkin from the dispenser.
A long and unfilled need exists for a dispensing system that provides satisfactory one-at-a-time dispensing for individual folded webs. This unfilled need extends to a dispensing system for individual folded webs 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 a dispensing system for individual folded webs having an area of non-uniform thickness across the length of the web from a stack of such individual folded webs. The dispensing system is composed of: (a) an outer housing defining an interior space; (b) stacking means mounted within the outer housing for holding a stack of individual folded webs within the interior space; (c) a dispensing face defined in the outer housing proximate to an end of the stacking means, the dispensing face defining a dispensing throat; (d) a stack of individual folded webs having an area of non-uniform thickness across the length of the web; and (e) at least one recessed section along at least one edge of the dispensing throat which contacts the stack of individual folded webs so that a portion of the stack of individual folded webs projects outward from the dispensing throat.
According to the invention, the dispensing face has a central portion projecting out from the dispenser in the form of a first surface and a second surface joined at an obtuse angle. The dispensing throat is located in the central portion at about the intersection of the first and second surfaces.
One feature of the invention is that the stack of individual folded webs having an area of non-uniform thickness across the length of the web is aligned so that an area of greatest thickness extends across the width of the dispensing throat.
In an embodiment of the invention, the stacking means may be composed of at least one restricting rib positioned against the stack of individual folded webs to maintain alignment of the stack so that the area of greatest thickness extends across the width of the dispensing throat during dispensing. For example, two or more restricting ribs may be positioned against the stack of webs so that displacement of the stack is minimized during dispensing which helps maintain proper alignment of the stack of webs. The restricting ribs may be mounted on an interior surface of the outer housing. Desirably, the restricting ribs are positioned so the run longitudinally along the stack of webs.
In another embodiment of the invention, the dispensing system may also include a staging area proximate the dispensing throat for spacing and slowing individual folded webs as they approach the dispensing throat. The staging area may include at least two curved bumpers oriented so as to be parallel to the path of travel of the individual folded webs as they approach the dispensing throat. A number of ribs, ridges, nobs or the like may be defined on the bumpers for temporarily arresting movement of the individual folded webs as they approach the dispensing throat.
According to the invention, the stack of individual folded webs contains individual webs composed of: (a) a first, central panel; (b) a second panel, unitary with said first panel and folded over a first side of said first panel; (c) a third panel, unitary with the first panel, and folded over a second side of the first panel; (d) a fourth panel, unitary with the second panel, and folded so as to be positioned between the first and second panels; and (e) a fifth panel, unitary with the third panel, and folded so as to be positioned between the first and third panels, such that a portion of the third panel and fifth panel overlap a portion of the second panel and fourth panel generating an area of non-uniform thickness across the length of the web. The stack of individual folded webs may be a stack of fibrous webs. Desirably, the stack of folded webs is a stack of absorbent paper webs such as, for example, absorbent paper napkins.
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. 4 and 5
, there is shown an exemplary dispensing system. The system includes an outer housing
32
defining an interior space
34
that contains a stacking means
36
(shown in
FIG. 6
) which is mounted within the outer housing
32
for holding a stack of individual folded webs (e.g., paper napkins)
38
of the type herein described within the interior space
34
.
The system also includes a dispensing face
40
defined in the outer housing
32
proximate to an end of the stacking means
36
.
The dispensing face
40
has a central portion
42
projecting out from the outer housing
32
and a dispensing throat
44
located in the central portion
42
. The dispensing throat
44
is defined by the edges of the dispensing face and should have a width that is slightly less than the width of the individual folded web (e.g., paper napkin) that is to be dispensed. The dispensing throat
44
has a top edge
46
, a bottom edge
48
, a first side edge
50
and a second side edge
52
.
Referring now to
FIG. 5
, it can be seen that the central portion
42
of the dispensing face
40
projects out from the outer housing
32
of the dispenser. The central portion
42
of the dispensing face
40
projects out in the form of a first surface
54
and a second surface
56
joined at an obtuse angle a (i.e., greater than 90 and less than 180 degrees). The dispensing throat
44
should be located at about the intersection
58
of the first and second surfaces
54
,
56
where there is a crease or break in the plane of the dispensing face
40
. It is contemplated 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. For example, the angle α may range from about 173 degrees to about 162 degrees. As another example, the angle a may range from about 170 degrees to about 165 degrees.
One feature of the present invention is the one or more recessed sections
60
along at least one edge of the dispensing throat which contacts the stack of individual folded webs so that a portion of the stack of individual folded webs projects outward from the dispensing throat. These recessed sections
60
are desirably located along the top edge
46
, first side edge
50
, and the second side edge
52
of the dispensing throat
44
which contact the stack of individual folded webs and should have dimensions such that a portion of the stack of individual folded webs projects outward from the dispensing throat.
By pressing against the stack of individual folded webs, the recessed portions
60
located at the first side edge
50
and the second side edge
52
also make it more difficult for a consumer to insert one or more fingers into the dispensing throat to grasp a clump of webs. Accordingly, wasteful dispensing of the folded webs is reduced.
Referring now to
FIG. 6
, the dispensing system includes a stacking means
36
which may be composed of at least one restricting rib positioned against the stack of individual folded webs
38
to maintain alignment of the stack so that the area of greatest thickness extends across the width of the dispensing throat
44
during dispensing. For example, two or more restricting ribs may be positioned against the stack of webs so that displacement of the stack is minimized during dispensing which helps maintain proper alignment of the stack of webs. The restricting ribs may be mounted on an interior surface of the outer housing. Desirably, the restricting ribs are positioned so they run along the stack of webs (e.g., longitudinally).
In an embodiment of the invention, the dispensing system may include a staging area proximate the dispensing throat for spacing and slowing napkins as they approach the dispensing throat. Referring now to
FIG. 7
, the staging area
62
may be composed of at least two bumpers
64
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
66
defined on the bumpers
64
for temporarily arresting movement of the napkins as they approach the dispensing throat.
The bumpers
64
, in combination with a spring loaded plate
68
that pushes against the stack of napkins
38
, may enhance the action of the recessed portions
60
of the dispensing throat
44
causing the napkins to bow out or buckle into the dispensing throat
44
. Such a configuration is believed to aid dispensing of the napkins by causing the napkins to feed into the dispensing throat
44
relatively uniformly and relatively independent of how full the dispenser is during dispensing. The bumpers also assist the stacking means
36
in centering 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.
According to the invention, the dispensing system is designed to work with a stack of individual folded webs instead of overfolded webs or interfolded webs. The stack of individual folded webs may be a stack of fibrous webs. Desirably, the stack of folded webs is a stack of absorbent webs such as, for example, an absorbent nonwoven product. More desirably, the stack of folded webs is a stack of absorbent paper webs such as, for example, paper napkins, paper towels, tissues or the like.
The individual folded webs are composed of: (a) a first, central panel; (b) a second panel, unitary with said first panel and folded over a first side of said first panel; (c) a third panel, unitary with the first panel, and folded over a second side of the first panel; (d) a fourth panel, unitary with the second panel, and folded so as to be positioned between the first and second panels; and (e) a fifth panel, unitary with the third panel, and folded so as to be positioned between the first and third panels, such that a portion of the third panel and fifth panel overlap a portion of the second panel and fourth panel generating an area of non-uniform thickness across the length of the web.
More particularly and with reference to
FIG. 8
, the folded web “F” includes a first, central panel
100
that has a first fold line
102
at a first end
104
and a second fold line
106
at a second end
108
that is opposite from the first end
104
. The folded web “F”, further includes a second panel
200
having a first end
202
that is joined with the first panel
100
at the first fold line
102
and a second end
204
having a third fold line
206
defined thereat. A third panel
300
having a first end
302
that is joined with the first panel
100
at the second fold line
106
further includes a second end
304
having a fourth fold line
306
defined thereat. The folded web “F” also includes a fourth panel
400
that is joined to the second panel
200
at the third fold line
206
. The fourth panel
400
is folded with respect to the second panel
200
at the third fold line
206
so that fourth panel
400
is positioned substantially between the first panel
100
and the second panel
200
. Similarly, the folded web “F” includes a fifth panel
500
that is joined to the third panel
300
at the fourth fold line
306
. The fifth panel
500
is folded with respect to the third panel
300
at the fourth fold line
306
so that the fifth panel
500
will be positioned substantially between the third panel
300
and the first panel
100
when folded as shown in
FIGS. 8
,
9
and
10
.
A first edge “E” of the folded web “F” is defined on an end of the fourth panel
400
that is opposite from the third fold line
206
. Similarly, the folded web “F” includes a second edge “E′” that is on the fifth panel
500
and is positioned opposite from the fourth fold line
306
. Since the fourth and fifth panels
400
,
500
are folded so as to be between the second and third panels
200
,
300
, respectively, and the first panel
100
, the first and second edges E, E′ will not be readily visible to an observer.
An important feature of the present invention is that the combined width of the second and third panels
200
,
300
are greater than the width of the first panel
100
, which will insure that the web product “F” has a zone or region of non-uniform thickness extending across the length of the folded web product in a central region when the product is folded flat.
The width of the first panel
100
is defined as being the distance from the first fold line
102
to the second fold line
106
. The width of the second panel
200
is defined as being the distance from the first fold line
102
to the third fold line
206
, and the width of third panel
300
is defined as being the distance from the second fold line
106
to the fourth fold line
306
.
A mid-point
70
of the distance on first panel
100
between first fold line
102
and second fold line
106
is indicated in
FIGS. 8 and 11
. In the embodiment of
FIGS. 8
, and
11
, the second panel
200
and the third panel
300
have the same width which, in combination, is greater than the width of the first panel
100
. This causes the third fold line
206
to be positioned on an opposite side of the mid-point
70
from first fold line
102
and the fourth fold line
306
to be positioned on the opposite side of the mid-point
70
from the second fold line
206
. Such a configuration causes a portion of the second panel
200
and fourth panel
400
to overlap a portion of the third panel
300
and fifth panel
500
generating a zone or region
80
of non-uniform thickness across the length of the folded web “F”. As can be seen in
FIGS. 8 and 11
, the zone or region
80
of non-uniform thickness is centered on the mid-point
70
.
In the embodiment of
FIG. 9
, the second panel
200
has a width that is less than the width of the third panel
300
. Importantly, the combined width of the second panel
200
and the third panel
300
is greater than the width of the first panel
100
so a portion of the second panel
200
and fourth panel
400
to overlap a portion of the third panel
300
and fifth panel
500
generating a zone or region
80
of non-uniform thickness across the length of the folded web “F”. The lack of symmetry between the second panel
200
and the third panel
300
shifts the zone or region
80
of non-uniform thickness away from the mid-point
70
. Such a configuration is desirable for dispensers having an offset opening.
According to an embodiment of the invention, the width of the fourth panel
400
may be less than one-half the width of the second panel
200
. Alternatively and/or additionally, the width of the fifth panel
500
may be less than one-half the width of the third panel
300
. Such a configuration enhances the difference in thickness (i.e., the non-uniform thickness) of the folded web product by concentrating the overlaying of the panels in the central region of the folded web product. For example, in the center of the folded web product, portions of the second panel
200
, the fourth panel
400
, the first panel
100
, the fifth panel
500
and the third panel
300
will be stacked on over each other to provide a thickness equivalent to five (
5
) sheets of material. When the width of the fourth panel
400
is less than the second panel
200
(e.g., the fourth less than ½ the width of the second panel) and when the width of the fifth panel
500
is less than the third panel
300
(e.g., the fifth panel less than ½ the width of the third panel), the non-central regions or outer regions of the folded sheet product have a thickness equivalent to only two (
2
) sheets of material. Thus, the outer regions of the folded sheet product have a thickness that is less than one-half (i.e., ⅖) the thickness of the central region.
In the past, it was generally thought that folded web products should be configured to eliminate areas of non-uniform thickness. However, the configuration of non-uniform thickness in the present invention discussed above provides several advantages. Referring now to
FIG. 12
of the drawings, there is shown a front view illustration of a dispenser
———
26
containing an exemplary folded web product “F”. According to a feature of the present invention, the zone or region
80
of non-uniform thickness (which is aligned generally at the mid-point
70
or at some offset from the mid-point
70
) contacts only small, “centrally located” sections
82
of the dispenser instead of the entire upper edge
46
or lower edge
48
as with a conventional overfold type product.
Contact between the zone or region
80
of non-uniform thickness at only small, “centrally located” sections
82
of the dispenser helps to minimize the amount of area that can be pressed against face of the dispenser when it is spring-loaded or overfilled. It is generally thought that minimizing this area of contact (of the thickest portion of the stack of folded products) will help reduce friction between the spring-loaded or overfilled stack of folded web product so that sheets may be dispensed easily and reliably.
Another advantage of the zone or region
80
of non-uniform thickness at only the small, “centrally located” sections
82
of the dispenser is that the thinner sections of a stack of the dispensable folded web products are located at the upper and lower edges
30
of the dispenser. Since pressure on the stack of folded web products is focused at its thickest section (i.e., the zone or region
80
of non-uniform thickness) which contacts only a small portion of the dispenser, the thinner sections of the stack of web products which are in contact with a greater portion of the dispenser (i.e., the upper and lower edges
30
) are subjected to substantially less pressure from spring-loading or overfilling.
Yet another advantage of the present invention is that the configuration of the zone or region
80
of non-uniform thickness causes that portion of a stack of folded web product to tend to “bow out”, protrude, bulge, or project outward from the opening in the dispenser. This effect is greatly enhanced by placement of the recessed portions
60
at one or more edges of the dispensing throat. Since the zone or region is aligned generally at the mid-point
70
or at some offset from the mid-point
70
, the bulge or projection generally makes it easier to grasp an individual folded sheet product.
The present invention had been found to be particularly desirable for use with horizontally placed individual folded 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 the individual folded paper napkins. Of course, the dispensing system of the present invention may be used with vertically mounted dispensers such as, for example, vertically mounted napkin, tissue or towel dispensers.
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.
