Description
Many types of dispensing for sheet material provided in roll form
have been proposed heretofore; however, these previously proposed
cartons are generally comparatively expensive to produce and are
difficult to use because the sheet material to be unrolled from an
associated roll thereof is difficult to grasp, unroll, and
sever.
SUMMARY
This invention provides a simple and economical dispensing carton
for a roll of sheet material wherein such carton has an easily
shielded cutter and has means controlling a free terminal portion
of the sheet material to enable easier grasping, unrolling, and
severing of the sheet material to provide more efficient dispensing
thereof.

DESCRIPTION OF ILLUSTRATED EMBODIMENTS
Reference is now made to FIGS. 1 and 2 of the drawings wherein an
exemplary dispensing carton of this invention is illustrated and
designated generally by the reference numeral 20 and the dispensing
carton 20 rotatably supports a roll 21 of sheet material 22 and
enables efficient dispensing of such sheet material in a manner as
will be described in detail subsequently. The dispensing carton 20
may be utilized to dispense rolls of sheet material of all types
including sheet materials made of paper, plastic, metallic foil,
and the like.
The dispensing carton 20 has a front wall 23, a bottom wall 24, a
rear wall 25, a top wall 26, and a pair of end walls or ends each
designated by the same reference numeral 30. The top wall 26 is
foldably fastened to the rear wall 25 in a hinged manner and has a
closure flap 31 extending downwardly from the forward or swinging
end thereof.
The front wall 23 has a horizontally arranged dispensing slot means
or slot provided therein and designated generally by the reference
numeral 32 and the slot 32 has an overall length indicated at 33
which is longer than the corresponding width 34 of the sheet
material 22. In this example of the invention the slot 32 extends
substantially completely across the front wall 23 of the carton
20.
The dispensing carton 20 has a cutter 35 for the sheet material 22
and the cutter is in the form of a cutting knife having a
sawtoothed cutting edge 36. The cutter 35 is suitably fixed to the
front wall 23 and defines the top edge of such front wall. The
cutting edge 36 is a comparatively sharp edge and it has been found
that it is desirable to shield such edge so that a person will not
be injured thereby when the dispensing carton 20 is not in use or
during shipment and handling of such carton.
Although the shielding of the cutting edge 36 and hence the cutter
35 could be achieved by providing complicated and expensive
structure and dispensing carton provides shielding of such cutting
edge in a simple manner without requiring additional structural
components for the carton and without wasting sheet material 22. In
particular, it will be seen from FIGS. 1 and 2 of the drawings that
the sheet material 22 has a free terminal portion 40 which extends
outwardly through the slot 32 and the terminal portion 40 has a
terminal end 41 which extends over the cutter 35 and is tucked
behind the front wall 23 to thereby cover the cutter 35 and define
a shield for its sawtoothed edge 36. In addition, the width of the
top wall 26 and the construction of the closure flap 31 is such
that upon inserting such closure flap behind the front wall 23 the
terminal end 41 is sandwiched between the front wall and the
closure flap whereby the terminal end 41 is thus held firmly in
position to define the previously mentioned shield over the cutting
edge 36.
With the terminal end 41 thus held in position the carton 20 with
its roll 21 of sheet material 22 is ready for shipment in a safe
manner and this is the condition illustrated in FIGS. 1 and 2.
Further, it is a simple matter to commence the dispensing of sheet
material 22 from within the carton 20 merely by inserting a finger,
or the like, between the terminal end 41 and the closure flap 31 to
thereby pull the terminal end 41 free and commence the unrolling of
any desired length of sheet material 22 from the supply roll 21 and
severing of the desired length essentially in the manner
illustrated in FIG. 3 of the drawings.
The carton 20 has a pair of end supports 44 carried at opposite
ends thereof, see FIGS. 9 and 10, and each support 44 has an
inwardly facing antifriction surface 45 and an antifriction
cylindrical supporting surface 46. The cylindrical supporting
surfaces 46 of the end supports 44 are particularly adapted to
receive a pair of right circular cylindrical ends 50 of a core
member 51 which is utilized to support the roll 21 of sheet
material 22. The core member 51 with its cylindrical ends 50
supported on the supporting surfaces 46 enables the roller 21 to be
rotated merely by pulling the free terminal portion 40 of the sheet
material 22 and as the terminal portion 40 is pulled the
antifriction surfaces 45 and 46 assure efficient unwinding or
unrolling of the sheet material 22 from its roll 21 with minimum
drag. The end supports 44 may be made of any suitable material;
however, each support is preferably made of an antifriction plastic
material so that its antifriction surfaces 45 and 46 are provided
as an inherent part of the support 44.
Each end support 44 has a cutout 52 in the top front portion
thereof and in the completed carton 20 with the roll 21 carried
within such carton the cutouts 52 unable easy insertion of the
closure flap 31 behind the front wall 23. The end supports 44 may
have a configuration which corresponds to the configuration of the
end walls 30 whereby the roll 21 of sheet material with its core
member 51 may be easily inserted within the carton 20 merely by
loosely supporting the ends 44 on the cylindrical portions 50 and
inserting the roll 21, core member 51, and the supports 44 within
the carton 20. With this construction the carton 20 and its end
supports 44 may be reused once a particular supply roll 21 has been
exhausted merely by opening the top wall 26, removing the exhausted
supply roll 21, and inserting a new roll in the manner outlined
above.
As previously mentioned, the front wall 23 has the dispensing slot
32 extending thereacross and the slot 32 extends substantially
horizontally across such front wall and receives the free terminal
portion 40 of the sheet material 22 for dispensing purposes. The
carton 20 also has flap means shown in this example of the
invention as a plurality of hinged flaps 54, see FIGS. 5, 7 and 8,
extending across the dispensing slot 32 and each flap 54 has an
upper portion shown as an upper corner portion 55 which is
yieldingly held against the sheet material 22 for reasons which
will now be described in detail.
Any desired length 56 of sheet material 22 may be easily pulled
upwardly and out of the carton 20 essentially in the manner
illustrated by dotted lines at 57 in FIG. 3 and such desired length
or section 56 is then severed by pulling from the dotted line
position at 57 to the solid line position illustrated at 58 to
thereby sever such length against the cutting edge 36 of the cutter
35. However, if the dispensing slot similar to the slot 32 were to
be a comparatively large open slot of the type generally provided
in many previously proposed dispensing cartons there would be a
tendency, once the desired length of sheet material 56 had been
severed, for the free terminal portion 40 of sheet material which
would extend between such slot and the cutter 35 to fall by gravity
within the dispensing carton 20 and such terminal portion 40 would
thus be substantially temporarily inaccessible. To use a dispensing
carton with such a large open slot would require considerable
effort in retrieving the free terminal end after each desired
length of sheet material has been severed following a dispensing
operation.
However, the flaps 54 assure that sheet material 22 may be
dispensed from the carton 20 in an efficient manner. In particular,
the upper corner portions 55 of the flaps 54 engage the sheet
material 22 and after a desired length has been severed the corner
portions 55 urge the sheet material against that portion of the
front wall 23 defining the top portion of the slot 32 whereby each
flap 54 serves as a brake holding the terminal portion 40 from
dropping within the carton 20 to an inaccessible position.
The dispensing slot 32 in the front wall 23 is defined by a
rectilinear slit 60 extending across the front wall 23 and having a
length which is longer than the corresponding width of the sheet
material 22 and the slit 60 defines the length of the dispensing
slot 32. In this example of the invention the dispensing slot 32 is
also defined by a plurality of three cutout openings and, for
convenience, each cutout opening is designated by the reference
numeral 61 although the central cutout is larger than the
equal-size side cutouts. The cutouts 61 are of substantially
rectangular configuration and arranged so that an associated
rectangular flap 54 is defined between a pair of cutouts 61, see
FIGS. 3--5.
Each flap 54 is provided as an integral part of the front wall 23
and the top edge of each flap 54 is defined by an associated
portion of the slit 60 and each side edge 62 of each flap 54 is
defined by an associated cutout 61. Each flap 54 also has a base
portion 64 aligned with an upwardly facing edge 65 in the front
wall 23 which defines the bottom of the dispensing slot 32.
With the flaps 54 formed as an integral part of the front wall 23
it will be appreciated that each flap 54 inherently tends to assume
the solid line position illustrated at 66 in FIG. 8. Thus, upon
pulling the free terminal portion 40 of the sheet material 22
through the slot 32 the flap 54 will move to the dotted line
position illustrated at 67 in FIG. 8 so that the upper portion 55
of each flap 54 will yieldingly bear against the sheet material 22
to provide the above-described braking action and prevent the
terminal portion 40 from falling within the carton 20.
To control the resiliency of each flap 54 and its tendency to
return to the solid line position 66 illustrated in FIG. 8,
weakening means in the form of weakened line 70 may be provided to
define the base portion of each flap 54. The weakened line 70 is
defined by a plurality of spaced cuts arranged in a rectilinear
path and aligned with the bottom edge of the slot 32. Further, each
weakened line 70 assures that the upper portion 55 of each flap 54
will yieldingly bear against the sheet material 22 with a
substantially controlled force as determined by the nature of such
weakening means whereby the braking action provided by the flaps 54
is effectively controlled.
The weakening means 70 for each flap 54 is shown as being defined
by a plurality of spaced cuts in this example of the invention;
however, it will be appreciated that any suitable weakening
technique may be utilized. In addition, only two flaps 54 of
rectangular configuration are illustrated in this example with such
flaps being provided as an integral part of the single thickness
front wall 23; yet, it is to be understood that such flaps may be
provided as separate members and fixed to the front wall and that
any desired number of flaps may be provided including a single
flap, or more than two flaps.
The construction of the flaps 54 is carefully determined and their
combined width is only a portion of the length of the dispensing
slot 32 whereby the flaps 54 engage only a portion of the sheet
material 22. It will be appreciated that if the flaps were to
extend substantially completely across the full length of the slot
it would be very difficult to pull the sheet material from within
the carton 20 due to the high frictional drag created by the wider
flaps contacting the sheet material. Thus, the flaps 54 enable
unobstructed dispensing of sheet material from within a carton 20
and yet provide the braking action in the manner described
above.
The carton 20 has resilient means 72 supported between the
dispensing slot 32 and the cutter 35 and in this example of the
invention the resilient means 72 is fixed to the front wall 23
immediately adjacent the top of the dispensing slot 32, see FIGS.
4, 5, and 6. The resilient means 72 is particularly adapted to
normally yieldingly hold the terminal portion 40 of the sheet
material 22 to enable easy grasping thereof as by a thumb and
forefinger and at a location as indicated at 73 in FIG. 5.
A desired length 56 of sheet material 22 is unrolled from the roll
21 and severed essentially as illustrated in FIG. 3 and as
previously described. Upon pulling the base of a desired length of
sheet material against the cutter 35 the resilient means 72 is of
such a character that it is temporarily flattened against the front
wall 23 from its normal full size indicated by dotted lines at 75,
in FIG. 4, to a temporarily flattened condition indicated by solid
lines at 76. This capability of the resilient means 72 to be
temporarily flattened assures that a substantially straight cut is
provided to define the newly severed end 80, see FIG. 3, of a
particular desired length 56 of sheet material while assuring that
the sheet material 22 engaging the resilient means 72 is not torn
or damaged during contact against such resilient means.
The resilient means 72 may be made of any suitable material and in
this example of the invention is shown as being made of an easily
compressible foam product such as a foam rubber strip, for example,
having the general shape of a parallelepiped. The foam rubber strip
or block 72 is suitably fixed to the front wall 23 as by an
adhesive material acting between the inside surface of the foam
rubber strip and the outside surface of the front wall 23 and has a
thickness indicated at 81 in FIG. 6 which assures the terminal
portion 40 is held outwardly sufficiently to enable easy grasping
and as previously mentioned.
The foam rubber strip 72 may extend substantially along the entire
front wall 23 while being fixed in position above the dispensing
slot 32. However, in this example of the invention the strip 72 is
a comparatively short strip provided only in the central portion of
the front wall 23. It will also be appreciated that a plurality of
spaced strips similar to the foam strip 72 may be fixed in a
rectilinear path at predetermined spaced intervals across the front
wall 23 and between the dispensing slot 32 and the cutter 35.
The foam rubber strip 72 is of the type which is compressible with
minimum application of force upon urging the sheet material 22
thereagainst. Further, once a desired length of sheet material 22
has been unrolled and severed the remaining free terminal portion
40 has no forces acting thereagainst; thus it is only necessary for
the resilient character of the foam strip 72 to be such that it is
capable of moving the free terminal portion 40 outwardly from the
front wall 23 (see FIG. 6) to enable easy grasping and dispensing
of another desired length of sheet material 22.
The carton 20 has support means in the from of a plurality of
spaced support pads 82 fixed to the front portion of the bottom
wall 24 and a plurality of spaced support pads 83 fixed to the rear
portion of the bottom wall 24 adjacent the rear wall 25. The
support pads 82 and 83 prevent relative sliding movement between
the carton and an associated supporting surface 84, see FIGS. 3 and
11, on which the carton 20 may be supported particularly following
the unrolling of a desired length of sheet material from the roll
21 and during the pulling of the sheet material in a substantially
horizontal direction roughly parallel to the supporting
surface.
Although the support pads 82 and 83 may be of identical
construction, if desired, in this example of the invention the
support pads 82 are of one type and the support pads 83 are of
another type as will now be described in detail. In particular, the
support pads 82 have pressure-sensitive adhesive surface means
shown as a pressure-sensitive adhesive surface 85 which in addition
to preventing relative sliding movement adhesively holds the carton
20 against its associated supporting surface. The adhesive surfaces
85 of the pads 82 prevent the dispensing carton from toppling
during the severing of a desired length of sheet material 22.
Each pad 83 provided adjacent the rear wall 25 of the carton has a
friction surface 86 which in this example is not an adhering
surface but is a high friction surface. The surfaces 86 help
prevent sliding movement of the carton during the dispensing of
sheet material 22.
Each of the pads 82 and 83 has a cover in the form of a cover tape
90 which protects a surface 85 or 86 of its associated support pad
82 or 83 respectively. The tape 90 is normally used during storage
and shipment of the dispensing carton 20 with its roll 21 of sheet
material 22 and once the dispensing carton is ready for use each
strip of tape 90 is peeled away by grasping an edge thereof and
pulling essentially in the manner illustrated at 91 in FIG. 12.
Two types of support pads, namely support pad 82 having an adhering
surface and support pad 83 having a surface which resists lateral
movement, have been provided on the exemplary carton 20. However,
all of the pressure pads provided may be of identical construction,
such as, identical to the support pad 82, for example. Further, the
entire bottom wall 24 may be provided with either an adhering or a
high friction support pad or any number of pads may be provided on
the bottom wall 24 and arranged in any desired pattern.
The carton 20 may be formed in any suitable manner and made from
any suitable foldable material. It is preferably formed using a
single piece blank designated generally by the reference numeral 93
in FIG. 13 of the drawings. The blank 93 is made of paperboard, or
the like, and may have an exposed surface thereof laminated with
metallic foil (such as aluminum-containing metallic foil), suitably
colored, embossed, imprinted, or remaining plain, as desired. The
description of the blank will proceed by describing primarily those
structural portions which were not previously described in detail
in connection with the description of the carton 20. However, where
a detailed description was made previously in connection with the
carton, such description will not be repeated in connection with
the blank and corresponding component portions of the blank 93 will
be designated by the same reference numerals as in the carton
20.
The blank 93 is suitably cut and scored and adapted to be assembled
to define the resulting carton 20 and comprises a plurality of
parallel spaced-apart score lines 94, 95, 96, and 97 defining the
extent in one direction of the front wall 23 extending outwardly of
score line 94, bottom line 24 extending between score lines 94 and
95, backwall 25 extending between score lines 95 and 96, top wall
26 extending between score lines 96 and 97, and closure flap 31
extending outwardly of score line 97.
A pair of score lines 100 define opposite end edges of the backwall
25 and a substantially rectangular flap 101 extends outwardly of
each score line 100. Each flap 101 defines the inside flap of an
associated end wall 30 in the resulting carton 20.
The front wall 23 has a pair of score lines 102 defining its
opposite end edges and a substantially rectangular flap 103 extends
outwardly of each score line 102. Each flap 103 defines the middle
flap of an associated end wall 30 in the resulting carton 20.
The bottom wall 24 also has a pair of score lines 104 defining its
opposite end edges and each score line 104 has a substantially
rectangular flap 105 extending outwardly thereof. Each flap 105
defines the outside layer or surface of an associated end wall 30
upon folding the blank to define the resulting carton 20.
The cutter 35 provided in the carton 20 is preferably in the form
of a substantially elongated flat strip and is fastened in position
with the blank 93 in its flat form utilizing a plurality of spaced
rivets 106. Upon assembling the blank 93 the cutter 35 defines the
top edge of the front wall 23, as previously explained.
While present exemplary embodiments of this invention, and methods
of practicing the same, have been illustrated and described, it
will be recognized that this invention may be otherwise variously
embodied and practiced within the scope of the following
claims.
