BACKGROUND OF THE INVENTION
[0001] The present invention relates to dispensers for web materials, such as plastic film.
In particular, the invention relates to containers having a cutting device for cutting
across the material as it is dispensed.
[0002] Various containers are known for dispensing web material. Many of these containers
use an exposed serrated edge as the means for cutting the web material once dispensed
from the container. These serrated edges have several disadvantages. For example,
the sharp, exposed serrated edge can inadvertently cut the user or other material
that it contacts. Also, the user must engage the web material with the serrated edge
by holding the web material in one hand and the container in the other. This awkward
arrangement can lead to adverse results such as ineffective cutting, the web material
doubling over itself, and so on.
[0003] Some known containers include a track-guided cutting assembly to overcome the problems
associated with the use of a serrated edge. An example of such a container is described
in commonly assigned U.S. Patent Application Publication No.
U.S. 2005/0034585, in the name of Keith E. Antal, said application being herein incorporated by reference. This application describes
a box for a roll of web material, with a molded plastic track extending along the
box, parallel to the axis of the roll. A cutter is captive in the track. The web material
is led out of the box and across the track. The cutter is slid along the track, cutting
across the material.
[0004] The track described in the above-mentioned application of Antal is seated in a slot
formed in one side of the box. The slot may weaken the box, and the Antal application
proposes an additional reinforcing member. In addition, part of the height of the
track, and part of the height of the cutter, project above the side of the box. The
projecting parts may be inconvenient for packing and stacking the boxes, unless each
box is enclosed in a larger lid.
BRIEF SUMMARY OF THE INVENTION
[0005] The present invention in one aspect relates generally to a container for dispensing
selected portions of a web material retained within the container. The container has
an elongated opening in a wall thereof, through which the web material can be led
out of the container. A track is positioned on the exterior parallel to the slot so
that the web material can be laid across the track. A cutter slides along the track
to cut across the web material. At least in a packaged configuration for shipping,
the container has a compact geometrical profile, and the track and cutter do not extend
beyond that profile.
[0006] In one embodiment, two adjacent sides of the container are folded inwards to form
a recess along the edge where the two sides meet. The track is positioned within the
recess, engaging both of the folded inward sides of the recess.
[0007] In another embodiment, parts of two adjacent sides are folded inwards to form a recess
along the edge where the two sides meet. Parts of the two adjacent sides at the ends
of the recess are not folded inwards. The track is positioned within the recess. The
ends of the track are retained under the unfolded parts of the sides.
[0008] In another embodiment, the track and cutter do not project outward of imaginary continuations
of the two adjacent sides over the recess. A removable cover is provided over the
track and cutter, generally following the outline of the container profile without
the recess.
[0009] In a further embodiment, the cutter runs in a slot or cutter guide in the track.
The cutter has a projecting portion or handle by which a user can grip the cutter.
The cutter is configured to be rotatable or foldable into a shipping position to reduce
the profile of the cutter assembly during shipping.
[0010] In a further embodiment, the track is mounted on a part of the container that is
movable between a shipping position in which the cutter track is inside the exterior
profile of the container and an operative position in which the cutter track is outside
the exterior profile of the container and faces outwards.
[0011] The present invention in another aspect relates generally to a container for dispensing
selected portions of a web material retained within the container. The container has
an elongate opening in a wall thereof, through which the web material can be led out
of the container. A track is positioned on the exterior parallel to the slot so that
the web material can be laid across the track. A cutter slides along the track to
cut across the web material. Two adjacent sides of the container are folded inwardly
to form a recess along the edge where the two sides meet. The track is positioned
within the recess, engaging both of the inwardly folded sides of the recess.
[0012] The present invention in another aspect relates generally to a container for dispensing
selected portions of a web material retained within the container. A track is positioned
on the exterior so that the web material can be laid across the track. A cutter slides
along the track to cut across the web material. The track is mounted bridging side
edges of the container.
[0013] In one embodiment, the track has pairs of flanges along both sides of the track,
and free edges of adjacent sides of the container are received between the flanges.
[0014] According to an aspect of the present invention is a dispenser for containing a supply
of flexible web material and for dispensing a portion of the web material and severing
the portion from the remaining web material in the dispenser, comprising a container
formed by at least first, second, and third side walls serially connected to one another
along longitudinal edges thereof that form corners of the container and a pair of
opposite end walls connected to opposite end edges of the side walls, each of the
side walls having at least a major portion that is substantially planar and is angularly
oriented relative to the side walls adjacent thereto, the planar major portions of
the side walls defining an external geometric profile of the container; an elongate
opening defined in one of the side walls through which a portion of the web material
can be dispensed; one of the corners of the container defining a recessed area formed
by a first wall portion that connects with the first side wall and a second wall portion
that connects with the second side wall, the first and second wall portions extending
inwardly away from the external geometric profile and toward an interior of the container
and being connected to each other at a concave corner, such that the recessed area
is inside the external geometric profile; a polymer track affixed to the container
and disposed in the recessed area such that the track is inside the external geometric
profile; a cutter engaged with the track and slidable therealong for cutting a portion
of web material dispensed through the elongate opening and laid across the track,
wherein the cutter is entirely inside the external geometric profile; and wherein
the recessed area has a length less than that of the first and second side walls and
opposite ends of the track are overhung by non-recessed portions of the side walls.
[0015] Other embodiments of the invention are also described herein and claimed in the appended
claims.

DETAILED DESCRIPTION OF THE INVENTION
[0050] The present inventions now will be described more fully hereinafter with reference
to the accompanying drawings in which some but not all embodiments of the inventions
are shown. Indeed, these inventions may be embodied in many different forms and should
not be construed as limited to the embodiments set forth herein; rather, these embodiments
are provided so that this disclosure will satisfy applicable legal requirements. Like
numbers refer to like elements throughout.
[0051] In the drawings, there are shown various embodiments of a container for storing and
dispensing rolled web material, for example, plastic wrap. Referring to FIGS. 1 and
2 and initially especially to FIG. 1, a first form of container, identified generally
by the numeral
10, comprises a box
12 that is long and thin and is approximately square in cross section. The box
12 has a body with two ends
14, three sides
16, 18, 20, and a lid
22. One long edge of each of the sides
16 and
20 joins the long edges of the side
18. The lid
22 is hinged to the other long edge of the side
20. The lid
22 may include a flap that tucks inside the side
20 when the box is closed or may be removed by means of perforations (not shown). The
lid
22 can be opened for access to the interior of the box
12. A slot
28 is formed extending most of the length of the side
16. The slot
28 may be formed initially by scoring or otherwise forming a line of weakness through
the material of the side 16, to define a strip that can be removed from the box
12 or a flap that can be raised to open or expose the slot
28.
[0052] In use, plastic film or other web material
30 is retained on a hollow core
32 positioned within the box
12. The web material
30 may be, for example, polyethylene film, polyvinyl chloride film, gift-wrap paper,
freezer wrap paper, foil, or the like. The hollow core
32 may be supported for easy rotation on roll supports (not shown) formed on the insides
of the ends
14. For shipping, the material
30 and the core
32 may be contained entirely within the closed box
12. For use, a free end
34 of the film material
30 is led off the core
32 and through the slot
28 to the exterior of the box: The free end
34 may be positioned by opening the box
12, opening the slot
28, feeding the film material
30 through the slot
28, and closing the lid
22.
[0053] Referring now especially to FIG. 2, a recess
36 is formed along the edge of the box
12 where the sides
16 and
18 meet. The recess
36 is formed by scoring the sides
16 and
18 parallel to the edge, and folding strips of material
38 and
40 inward at the score lines
42, 44. The fold that would otherwise form the convex edge between the sides
16, 18 is inverted to form a concave edge between the strips
38, 40. The ends of the strips
38,
40 are formed by cuts
46 through the material of the sides
16, 18 a short distance from the box ends
14, so that at each end of the recess there is a short overhang section
48 where the sides
16, 18 extend to meet at a convex edge of the box. An opening
50 is formed between the recess
36 and the interior of the box
12 under the overhang
48. Further openings
52 are illustrated in the box side
16 (top) near each end of the recess
36 and serve as finger holes for assisting in grabbing web material. Alternatively,
overhangs
48 may be omitted, with the recess
36 continuing to the box ends
14.
[0054] Referring to FIGS. 2 and 3, a track or rail
60 is positioned in the recess
36. The rail
60 is generally pentagonal in cross section, with two basal faces
62 formed approximately at right angles. The basal faces
62 preferably do not meet, but form a gap
63 between them. Two substantially parallel side walls
64 extend from the outer edges of the basal faces
62. Two substantially coplanar distal faces
66 extend inwards from the distal edges of the side walls
64 and form between them a slot
68. The two sides of the rail
60 are connected by a transverse wall
69. The rail
60 is positioned in the recess
36, with the basal faces
62 positioned flat against the strips
38,
40 forming the recess
36. The gap
63 allows flexibility if the basal faces
62 are not at exactly the same angle as the box strips
38, 40. The rail
60 is so dimensioned that the entire rail
60 is inside the effective profile extension of the box sides
16, 18 above the recess
36. The distal faces
66 are outside an imaginary plane joining the fold lines
42, 44 at the edges of the recess, so that web material can readily be laid across the rail
60 in contact with the distal faces
66. The rail
60 is preferably longer than the recess
36, with the ends of the rail
60 located under the overhangs
48. The rail
60 may be substantially as long as the distance between the box ends
14. The rail
60 may be attached to the box
12 by strips of adhesive, double-sided adhesive tape or the like, attaching both basal
faces
62 to the strips
38, 40 forming the recess
36. Alternatively, the rail
60 may be retained solely by its ends being captive under the overhangs
48. Where the overhangs
48 are used to retain the rail
60, the ends of the rail
60 may be provided with end caps, or may be deformed to fit closely under the overhangs
48 so that the rail
60 does not tip over or move around undesirably in use.
[0055] A cutter assembly
70 is positioned within the rail
60. The cutter includes a foot
72 position, a neck
74 extending out through the slot
68, and a head
76 positioned outside the rail
60. Again, the head
76 is preferably positioned inside the effective profile extensions of the box sides
16, 18 above the recess
36. The neck
72 includes a cutter blade or blades. The cutter
70 is arranged to be slid along the slot
68, with the cutter blade(s) facing along the slot. The cutter
70 can be assembled with the rail
60 by inserting the foot
72 into the interior of the rail
60 from one end before the rail is assembled with the box
12, and before any end cap or deformed end is provided. When the container 10 is fully
assembled, the foot
72 is captive within the rail
60 in a sufficiently close fit relationship so as to restrain the cutter
70 from tipping or twisting. The cutter blade(s) may be of any form desired. The box
ends
14 may extend to the undersides of the overhangs
48, and may provide end stops for the cutter assembly
70. Where the overhangs
48 are not present, the box ends
14 may project outside the strips
38, 40 far enough to provide end stops for the cutter assembly
70. Alternatively, the rail
60 may be deformed at the ends, or provided with separate end stops.
[0056] The faces
66 of the rails
60 on which the web material
30 rests for cutting, or the surfaces of the box sides
16,
18 adjacent to the recess
36, may be made of, or coated with, a material that tends to retain the film material
30 weakly, for example, by cling, static cling, or tack. An example of materials for
use in retaining film during cutting is described in
U.S. Patent Application No. 11/071,422, filed March 3, 2005 in the name of Rudolf
Pavlik, which is incorporated herein by reference in its entirety.
[0057] As may be seen from the drawings and the above description, the cutter assembly
70 is clearly visible on the outside of the box
12, but is entirely within the box profile as defined by the faces
14, 16, 18, 20 and
22. Thus, the container
10 can be shipped and stored with the cutter assembly
70 assembled and installed, but can still be packed, stacked, and displayed efficiently
and stably like an ordinary rectangular box.
[0058] If the web material is cling wrap or other material that is to be used in contact
with food, it may be desired to protect the cutter assembly from potential contamination
during shipping and storage. It may also be desired to seal off any openings into
the interior of the box
12, such as the slot
28, the openings
50 under the overhangs
48 and the finger holes
52. The entire container
10 may thus be wrapped in any suitable wrapping material, such as, for example, shrink
wrap or non-shrink wrap. A guard, such as a rigid portion made of plastic or paperboard,
may be provided over the recess
36, and optionally also over the slot
28. Such a guard may be, for example, in the form of an L-shaped strip or in the form
of a cap over the entire side
16 and extending down the sides
18 and
22 and the ends
14. Such a guard may be retained in place by an outer wrapping, adhesive tape or the
like, or may be attached to the box
12 by a peelable adhesive. A flap may also be formed as part of the lid
16, initially extending over the recess 36 and attached to the box side
18. The end user may then tear off the parts of the flap that cover the recess
36 and the slot
28, and leave a short flap that can be tucked in under a slot in the box side
16 or the like.
[0059] In order for the potential purchaser to be able to see that the container
10 has a built-in cutter assembly, it may be preferred for the wrappings and coverings
over the recess
36 to be transparent.
[0060] In use, any external packaging or wrapping materials are removed. The container 10
may be supplied with a core
32 of web material
30 inside it or, especially if the container
10 is being reused, a separate roll of web material may be supplied by the user. The
length of the core
32, and the width of the web material
30, are selected such that the web material will pass through the slot
28, and such that the cutter
70 can travel over the entire width of the web material. The cutter may be arranged
to slide into the spaces under the overhangs
48 as far as the insides of the box ends
14, in order to increase the travel of the cutter and thus the width of web material
30 that the container
10 can dispense. The holes
52 are positioned so that the side edges of the web material
30 overlie the holes, and fingers can be inserted in the holes to grasp the edges of
the web material.
[0061] The cutter
70 is positioned at one end of the rail slot
68, but no other assembling or installation of the cutter assembly by the user is required.
The film material
30 is led out of the slot
28 in the box
12 and across the recess
36, and is laid down onto the distal faces
66 of the rail
60. The film material
30 is positioned with a desired length at the free end
34 beyond the slot
68, and laid down onto the box side
18. Then, the cutter
70 is slid across the film material
30 to the other end of the rail
60. The cut length of web material
30 is lifted off the box
12 and removed. When another cut length of the web material
30 is needed, the free end
34 is lifted by a finger in one or each of the holes
52 and moved forward across the rail
60. If the cutter
70 has a cutter blade at only one end, the cutter is returned to the starting position
before advancing the web material.
[0062] Referring now to FIG. 4, a second form of the rail
80 is generally pentagonal in cross section, with two basal faces
82 approximately at right angles. Two roughly parallel side walls
84 extend from the outer edges of the basal faces. Two roughly coplanar distal faces
86 extend towards each other from the distal edges of the side walls
84 and form between them a slot
88. Unlike the first form of rail
60, the basal faces
82 meet and join together the two sides of the rail
80. A transverse wall
69 is not required, and in the rail shown in FIG. 4 is not present. The second form
of rail
80 is dimensioned and positioned similarly to the first form of rail
60.
[0063] Referring now to FIG. 5, a third form of the rail
90 is generally triangular in cross section, with two basal faces
92 meeting approximately at right angles. Two roughly coplanar distal faces
96 extend inwards from the distal edges of the basal faces
92, without intervening side walls
64, 84 and form between them a slot
98. The rail
90 is positioned in the recess
36, with the basal faces
92 flat against the strips
38, 40 forming the recess. The rail
90 is so dimensioned that the edges between the basal faces
92 and the distal faces
96 are close to the fold lines
42, 44 at the edges of the recess
36. The foot
72 of the cutter
70 is appropriately shaped to fit into the triangular interior of the rail
90. The container
10 incorporating the third form of rail
90 is otherwise constructed or used in substantially the same way as the container
10 incorporating the first form of rail
60.
[0064] Referring now to FIGS. 6 and 6A, a second form of container and dispenser for web
material, indicated generally the reference numeral
110, comprises a box
112 of generally triangular prismatic shape, with two triangular ends
114, and three sides
116, 118, 120. The edges between the sides
116, 118, 120 as illustrated are rounded. However, a sharp angled transition (such as that illustrated
in FIGS. 7 and 8) or some other form may be provided, if so desired. One side
118 has a slot
122 similar to the slot
28 shown in FIG. 1, widened near the ends to form finger holes
124. The edge
126 between the sides
116, 118 is indented to form a recess
128 defined by two flat strips, similar to the recess
36 shown in FIGS. 1 and 2. By selecting the relationship between the width of the recess
128 and the curvature of the edge
126, a desired angle between the two flat strips, for example a recess with the strips
at right angles similarly to the strips
42, 44 shown in FIGS. I and 2, may be produced.
[0065] As shown in FIG. 6, the recess
128 does not extend the full length of the edge
126, and overhangs
130 remain at the ends. A rail
60, 80, 90 is positioned in the recess
128, and a cutter
70 slides in the rail, as described with reference to FIG. 2. The head
74 of the cutter
70 may be differently shaped from that shown in FIG. 2, because of the different constraint
of fitting the head
74 within the imaginary continuation of the sides
116, 118 and the curved edge
126. The container
110 shown in FIG. 6 is otherwise similar, and is used similarly, to the container
10 shown in FIGS. 1 to 3. Containers
110 may be stacked and stored as triangular prisms.
[0066] Referring now to FIG. 7, a further form of container indicated generally by the reference
numeral
140 comprises a box
142, which is shown in FIG. 7 as a triangular box, with a cutout
144 along most of the length of an edge
146 between two sides
148, 150. A rail
152 comprises a base
154, two side walls
156 upstanding from either side of the base, and two distal walls
158 extending inwards from the distal edges of the side walls
156 and defining a slot
160. A cutter
70 fits into the rail
152 and projects through the slot
160, as described above with reference to FIGS. 2 and 3. The rail
152 has two pairs of legs
162, 164 extending downwards and outwards from the base
154. Each pair of legs
162, 164 defines a slot into which the edge
166 of one of the box sides
148,150 fits. The inner legs
164 are flexible, and are angled inwards at their free edges
168 so that the free edges fit between the box edges
166.
[0067] To assemble the container
140, the rail
152 is pushed onto the box edges
166. The leg free edges
168 fit between the box edges
166, and as the rail is pushed in the inner legs
164 deflect inwards and then snap outwards, holding the rail
152 in place. When the rail
152 is fully in place, the box sides
148, 150 may be gripped between the outer rail legs
162 and the resilient inner legs
164, if the spacing between the legs in their unstressed condition is less than the thickness
of the box sides
148, 150. Alternatively, or in addition, the legs
162, 164 may be secured to the box sides
148, 150 by adhesive.
[0068] Referring now to FIGS. 10 to 12, a further form of container indicated generally
by the reference numeral
170 comprises a box
172 with a lid
174 that overlies approximately half of one side
176 of the box and is hinged at
177 along the midline of the box side
176. The free edge
178 of the lid
174 is provided with a tab
180 that fits into a slit
182 in the edge of the side
176 to locate and secure the lid when the lid is closed. A slot
184, through which web material
30 is led out of the box
172, is formed in the box side
176 under the lid
174. A rail
186 with a cutter
188 is attached to the underside of the lid
174, and is so positioned that when the lid is closed the rail projects through the slot
184 into the interior of the box
172.
[0069] The container
172 is shipped and stored with the lid
174 closed, as shown in FIG. 10, and then has a rectangular shape that is easily and
efficiently stored, stacked, and displayed. To use the container, the lid
174 is opened, from the condition shown in FIG. 10, in the direction of the arrows in
FIGS. 10 and 11, to the open condition shown in FIG. 12. When the lid
174 is open, the lid overlies the other half of the box side
176, with the rail
186 and cutter
188 exposed. As shown in FIG. 12, the web material
30 is then led out of the slot
184 and across the rail
186, where it may be cut off by the cutter
188.
[0070] Referring now to FIG. 13, a further form of container indicated generally by the
reference numeral
200 comprises a generally square or rectangular box
202 formed by a series of four serially connected walls comprising a first wall
206, a second wall (not numbered) connected to the first wall and perpendicular thereto,
a third wall (not numbered) connected to the second wall and perpendicular thereto
(and therefore parallel to the first wall
206), and a fourth wall
208 connected to the third wall and perpendicular thereto (and therefore perpendicular
to the first wall
206). The first wall
206 has a smaller width than the opposite third wall, and the fourth wall
208 has a smaller width than the opposite second wall. The box has an angled corner formed
by a sloping wall
204 that extends between one edge of the first wall
206 and an adjacent edge of the fourth wall
208. A rail
210 with a cutter
212 is mounted on the sloping wall
204, inside the imaginary extensions of the walls
206,
208. A slot
28 is formed in the first wall
206. A lid
214 is hinged to the box 202 at the edge of the first wall
206 farther from the sloping wall
204. The lid covers the first wall
206 and has skirts or covers
216 on all sides except the hinge side.
[0071] When the lid
214 is closed the skirts
216 overhang the side edges of the box
202 and the top edge of the fourth wall
208, completely enclosing the rail
210 and cutter
212. The lid
214 may be of transparent material, so that the rail and cutter assembly is visible when
the lid is closed. When the lid is opened, the slot
28 and the cutter assembly
210, 212 are preferably exposed. Web material may then be fed out of the slot
28 and over the rail
210. Lengths of web material may then be cut off and dispensed as described above.
[0072] Referring now to FIGS. 14 and 15, a further form of container indicated generally
by the reference numeral
220 comprises a box
222 with an angled corner formed by a sloping wall
224 that extends between two adjacent orthogonal sides
226, 228 of the box. A rail
230 with a cutter
232 is mounted on the sloping wall
224, inside the imaginary extensions of the sides
226, 228. As shown in FIG. 14, the sloping wall
224 is angled inwards from the plane of the side
226. A slot
28 is formed in the box side
226. A lid
234 is hinged to the box
222 along the angle where the box side
226 and the sloping wall
224 meet. The free edge of the lid
234 is secured to the box side
228 by a fastener
236, such as adhesive tape
236, hook and loop type fasteners, or the like. The lid has two end skirts extending beyond
the sloping wall
224 at the box ends and a front skirt
234A, as best shown in FIG. 15.
[0073] When the lid
234 is closed the skirts
238 overhang the ends of the box
222 and the lid is fastened to the box side
228, compieteiy enclosing the cutter assembly
230, 232. The lid
234 may be of transparent material, so that the cutter assembly is visible when the lid
is closed. To bring the container
220 into use as a dispenser, the fastener
236 is released, and the lid
234 is opened. The lid
234 is then torn off along the line where the lid joins the box side
236, exposing the rail and cutter assembly
230, 232. Web material may then be fed out of the slot
28 and over the rail
230. Lengths of web material may then be cut off and dispensed as described above.
[0074] Referring now to FIG. 16, a further form of container indicated generally by the
reference numeral
240 comprises a box
242 with two adjacent sides
244, 246 that meet at a corner
247. The side
244 has a skirt
248 that extends round the corner and overlies a free edge
250 of the side
246. A rail
252 for a cutter assembly is mounted on the inside (with the box closed) of the side
246 near the free edge
250, with a preformed fold line
254 in the box side
246 on the side of the rail
252 away from the free edge
250. A preformed fold line, tear line, tear strip or the like
256 is formed in the box side
244 near to the corner
247. The free edge
250 of the box side
246 is thus retained under the skirt
248. During shipment of the container, skirt
248 is preferably secured to box side
246, by adhesive or the like.
[0075] To open the box, the skirt portion
248 is torn off or folded back at the line
256, releasing the free edge
250 of the box side
246. The box side
246 is then folded back at the fold line
254, so that the part carrying the cutter rail
252 lies flat against the outside of the box
242, with the cutter rail exposed. An adhesive or fastener is preferably provided to secure
the free edge
250 to the face of the box side
246. Web material may then be led out of the box
242 through the gap formed between the fold line
254 and the fold or tear line
256, and laid over the cutter rail
252. Lengths of web material may then be cut off by a cutter assembly (not shown) riding
in the gap of the rail and dispensed as described above.
[0076] Referring now to FIGS. 17 and 18, a further form of container
260 comprises a box
262, one side
264 of which comprises two flanges
266, 268 extending from the adjacent box sides
270, 272 and defining between them a space
274. An outer panel
276 covers the box side
264 and is bonded to the flanges
266,
268. The middle of the outer panel
276 has a cutter rail
278 attached to its inner side where the panel spans the space
274. The outer panel
276 is provided with a tear strip
280 near to the free edge of one flange
266. The outer panel
276 may be formed with a fold line near to the free edge of the other flange
268. Alternatively, the edge between the unsupported outer panel
276 and the outer panel bonded to the flange
268 may provide a sufficiently definite fold line.
[0077] To open the box
262, the middle of the outer panel
276 is separated from the flange
266 by use of the tear strip
280, and the unsupported middle of the outer panel is folded back at the free edge of
the flange
268 as shown by the arrow
282 in FIG. 18, until the cutter rail
278 lies, facing outwards, on the flange
268 or the box side
272. Web material from inside the box
262 may then be led out through the space
274 and laid over the cutter rail
278.
[0078] Referring now to FIGS. 19 and 20, a further form of container
290 comprises a box
292 with adjacent sides
294, 296. The box sides
294, 296 do not meet. A cutter rail
298 occupies the corner between the box sides
294, 296. The cutter rail
298 comprises a generally tubular guide
300. Part of the guide
300 is preferably of rectangular section, with two flat faces
302,
304 forming a corner
306 of the box
292. The flat faces
302,
304 are extended as outer flanges
308,
310 overlying the box sides
294, 296 on the outside of the box
292. A slot
312 extending along the length of the tubular guide
300 opens through one of the flat faces
302. Inner flanges
314, 316 extend from the tubular guide
300 overlying the box sides
294, 296 on the inside of the box
292. Free edges of the box sides
294, 296 are inserted between the outer and inner flanges
308, 314 and
310, 316 as shown by the arrows in FIG. 19, and secured by adhesive. Alternatively, the box
sides
294, 296 may be interference fits between the outer and inner flanges
308, 314 and
310, 316.
[0079] A cutter 320 comprises a foot 322 that is captive in the tubular guide 300, a neck
324 that in an operating position of the cutter assembly as shown in FIG. 20 extends
through the slot 312, and a handle or head 326 that in the operating position overlies
the flat face
302 of the rail
298. The foot
322 is roughly cylindrical, so that it can rotate about the longitudinal axis of the
tubular guide 300 as explained below. A cutter blade is provided on the neck 324 for
cutting web material 30 laid over the rail 298. Near one end of the rail 298, a cutout
328 is provided in the box side 326, in the flat face 304 of the rail 298, in the
part of the flat face
302 between the corner
306 and the slot
312, and in the side of the tubular guide 300 facing the flat face 304. As shown in FIGS.
19 and 20, the cutout 328 is as long in the lengthwise direction of the rail 298 as
is the head 326 of the cutter 320. The foot 322 of the cutter 320 is longer than the
cutout 328.
[0080] When the cutter 320 is slid to a position level with the cutout 328, the cutter can
be rotated about the longitudinal axis of the tubular guide 300, with the head and
neck of the cutter swinging sideways into the cutout 328. The cutter 320 can rotate
into a non-use position, as shown in FIG. 19, in which the neck 324 and head 326 are
approximately on the opposite side of the tubular guide 300 from the slot 312. The
cutout 328 does not extend round the back of the tubular guide 300, and the non-use
position of the cutter 320 is determined by the neck 324 of the cutter abutting the
back of the cutout in the tubular guide. The width of the head 326 of the cutter 320
is selected so that in the non-use position the head is approximately flush with or
slightly recessed behind the outer surface of the box side 296, but is not behind
the inner flange 316. The inner flange 316 then prevents the cutter 320 from moving
axially out of alignment with the cutout 328 when the cutter is in the non-use position.
Alternatively, the part of the cutout 328 in the tubular guide 300 within which the
neck 324 of the cutter 320 rests in the nonuse position may be only as long as the
neck
324, or another baffle may be provided to prevent the cutter moving axially behind the
box side 296 in the non-use position. The part of the cutout 328 in the box side 296
extends away from the corner 306 further than the head
326 of the cutter
320, enabling a user's finger to be inserted.
[0081] For shipping and storage, the cutter 320 is placed in the non-use position within
the cutout 328. The container 290 then has a substantially rectangular profile, with
the faces 302, 304 of the rail 298 projecting only slightly above the box sides 294,
296. The slot 312 and the cutout 328 may be covered by a lid, wrapping, or other cover
as discussed above. To use the container 290, the user removes any cover, inserts
a finger into the cutout 328, and swings the head 326 of the cutter 320 out in the
direction of the arrow 330 in FIG. 19 into the operating position shown in FIG. 20,
in which the cutter can be slid along the slot 312. Web material is then led out of
the interior of the box
292 through a slot (not shown in FIGS. 19 and 20) and laid on the flat face
302 across the rail slot
312. A desired length of web material is then cut off by sliding the cutter along the
rail 298 as described above. For subsequent storage, the cutter 320 may be either
returned to the non-use position or left in the operating position at one end of the
rail slot 312.
[0082] Referring now to FIGS. 21 and 22, a further form of container indicated generally
by the reference numeral 340 comprises a box 342, one side 344 of which has, in a
non-use condition as shown in FIG. 21, a recessed channel 346. The channel 346 is
generally rectangular in section, with two side walls 348 and a bottom wall 350. A
cutter rail 352 is mounted on the bottom wall 350 of the channel 346. Each of the
side walls 348 has a trapezoidal fluted section 354 formed by a mid-facet 356, generally
parallel to but offset from the main plane of the side wall 348, and two oblique facets
358 joining the edges of the mid-facet 356 to facets 360 of the side wall in the main
plane on either side of the fluted section. The angles between the various facets
are creased sharply enough that under an applied force the side walls 348 tend to
flex at the creases without crumpling or bending the facets. The cutter rail 352 is
mounted on the mid facet 362 of a fluted section 364 formed in the bottom wall 350.
[0083] In the non-use condition shown in FIG. 21, for shipping, storage, and display, the
channel 346 is inside the outline of the box as defined in part by the plane of the
box wall 344, and all of the fluted sections 354, 364 project into the interior of
the channel 346. As may be seen from FIG. 21, the underside of the flute 364 renders
the bottom wall 350 of the channel 346 concave towards the middle of the box
342, increasing the space available for a core
32 of web material
30 in the box
342. The channel
346 is covered by a strip of material
366 that is bonded to the box side
344 on either side of the channel with peelable adhesive. The container
340 is thus substantially rectangular in shape.
[0084] For use, the user removes the covering strip
366, reaches into the channel
346, grasps the cutter rail
352, and pulls. Alternatively, if the box
342 can be opened, the user may push from the other side of the bottom wall
350. The flexibility provided by the fluted sections
354 allows the entire channel
346 to be inverted so that the channel projects outward from the box wall
344, with the cutter rail
352 on top of the channel. As shown in FIG. 22, the flute
364 is separately inverted, so that the flute
364 is concave outward, with the cutter rail
352 in the concavity. The upper surfaces
353 of the cutter rail
352 are then closer to the plane of the outer facets
368 of the channel bottom wall
350, allowing web material
30 to be laid smoothly over the channel bottom wall and the cutter rail for cutting.
The bottom wall
350 of the channel
346 defines a slot
28 through which the web material
30 is led out from the container.
[0085] As illustrated in FIGS. 21 and 22, there is a number of surface elements designed
to create flexibility in the channel
346. Other configurations are contemplated to create this function for the wall construction,
such as accordion style bellows, etc.
[0086] Referring now to FIGS. 23 and 24, a further form of container indicated generally
by the reference numeral
370 comprises a box
372, one side
374 of which has, in a non-use condition as shown in FIG. 23, a recessed channel
376. The channel
376 is generally triangular in section, with two side walls
378, 380. A cutter rail
382 is mounted on one of the side walls
380 of the channel 376. The cutter rail is positioned and dimensioned so that it does
not project above the plane of the box side
374.
[0087] In the non-use condition shown in FIG. 23, for shipping, storage, and display, the
channel
376 is covered by a strip of material
384 that is bonded to the box side 374 on either side of the channel with peelable adhesive.
The container 370 is thus substantially rectangular in shape.
[0088] For use, the user peels off the cover strip 384, and then inverts the channel 376
to the position shown in FIG. 24, projecting outward from the box side 374, with the
cutter rail 382 on the outside. Because of the triangular shape of the channel 376,
inverting the channel typically involves spreading the outer facets of the box side
374 apart, or bending one or more of the facets of the channel 376. The required flexibility
is taken into consideration in determining the materials and construction for the
box 372.
[0089] Referring now to FIGS. 25 and 26, a further form of container 390 is generally similar
to the container 370 shown in FIGS. 23 and 24. Reference is made to the description
of FIGS. 23 and 24, which will not be unnecessarily repeated. Like reference numerals
are used for like elements in both forms of container 370 and 390. However, the cutter
rail 382 shown in FIGS. 23 and 24 is generally rectangular in cross section, so that
the distal surface on which the web material is laid for cutting is parallel to the
box facet 380 to which the rail is attached. As may be seen from FIG. 24, this may
result in the cutter being positioned in use at an angle that is awkward for the user,
or does not assist laying the web material smoothly over the cutter rail 382 for cutting.
In FIGS. 25 and 26, the cutter rail 392 is wedge-shaped in cross section, so that
in the operating position shown in FIG. 26 the cutting surface 394 of the cutter rail
is roughly parallel to the plane of the box side 374.
[0090] In FIGS. 23 through 26, the channel
374 is shown with sides
378, 380 of different lengths, and thus at different angles to the plane of the box side 374.
The cutter rail 382 in FIGS. 23 and 24 is shown mounted on the shorter, steeper, channel
side 380. The cutter rail 392 in FIGS. 25 and 26 is shown mounted on the longer, more
gently sloped, channel side 378.
[0091] Either cutter rail may be mounted on either slope, with appropriate adjustment to
the shape of the cutter rail
392 for the angle of the slope on which it is mounted, and with appropriate selection
of the position of the cutter rail so as not to project through the cover strip
384 in the non-use condition.
[0092] Referring now to FIG. 27, a further form of container, indicated generally by the
reference numeral
400, comprises a box
402 with a cutter assembly, comprising a cutter rail 404 and a cutter 406, at a corner
between adjacent sides
408, 410. The cutter rail
404 has outer flanges
412 and inner flanges
414 holding between them free edges of the box sides
408, 410. The cutter rail
404 may be fastened to the box edges by adhesive, or may be an interference fit. The
cutter rail
404 has an angled corner
416, in which is a slot
418 in which the cutter 406 runs. The cutter has a head
420 projecting from the rail slot
418. The head
420 is dimensioned so that it does not project beyond the imaginary continuations of
the outer surfaces of the box sides
408, 410. The container
400 has a lid
422 that covers the box side
408, including a slot
28 for web material
30. The lid
422 has skirts
424 that extend down over the cutter rail
404. The lid may be of transparent material so that, when the container
400 is displayed in a store, the cutter assembly
404, 406 and printed material on the box side
408 are visible to potential purchasers.
[0093] Referring now to FIG. 28, a further form of container, indicated generally by the
reference numeral
430, comprises a triangular box
432 with a cutter assembly, comprising a cutter rail
434 and a cutter
436, at a corner between adjacent sides
438, 440. The cutter rail
434 has outer flanges
442 and inner flanges
444 holding between them free edges of the box sides
438, 440. The cutter rail
434 may be fastened to the box edges by adhesive, or may be an interference fit. The
cutter rail
434 has an angled corner
446, in which is a slot
448 in which the cutter
436 runs. The cutter has a head
450 projecting from the rail slot
448. The head
450 is dimensioned so that it does not project beyond the imaginary continuations of
the outer surfaces of the box sides
438, 440. If the box
432 has rounded corners, the cutter head
450 may be dimensioned so that it does not project beyond the curve of the rounded corner.
The container
430 has a cover
452 that fits over the cutter assembly
434, 436 and is fastened to the box sides
438, 440 by adhesive tape
454. The cover
452 has a rounded corner
456 that matches the curvature of the other corners of the box
432. The cover
452 may be of transparent material so that, when the container
430 is displayed in a store, the cutter assembly
434, 436 is visible to potential purchasers. A slot
28 for the web material is provided in the side wall
440 adjacent the cutter assembly.
[0094] Referring now to FIG. 29, a further form of container, indicated generally by the
reference numeral
460, comprises a box
462 with adjacent sides
464, 466. A cutter assembly comprising a cutter rail
468 and a cutter
470 is mounted in the corner between the adjacent sides
464,
466. The cutter rail
468 has outer flanges
472 and inner flanges
474 that receive between them the free edges of the adjacent sides
464, 466. The cutter rail
468 comprises a recess
476, within which are a cutter guide
478 and the cutter
470. The cutter guide
478 has a surface
480 with a slot
481 in the surface. A neck
482 of the cutter
470, carrying a cutter blade
484, projects from the rail slot
481 to cut web material
30 that is laid across the surface
480. A slot
486 is formed in the extension of the rail
468, between the cutter guide
478 and the flanges
472, 474 that receive the box side
464. The slot
486 is positioned so that web material
30 can be led from inside the box
462 out of the slot
486 and across the surface
480 of the cutter guide
478. At one side of the cutter rail
468, the outer flange
472 is offset outwards from an adjacent part of the cutter rail, forming a step
488. An edge of a lid or cover
490 seats in the step
488. A similar step may be formed at the other side of the cutter rail, and the cover
490 seated in both steps. Alternatively, the other side of the cover
490 may be attached to the box
462 in another way.
[0095] Referring to FIGS. 30-32, a further form of container
510 is illustrated comprising a box
512 having a generally elongated rectangular configuration with a central recess
536 in the top surface
516. The recess
536 is defined by two angled strips
538, 540 and a trough
539; the trough
539 has one or more slots
528 therein. The box
512 contains two separate rolls
532A, 532B of web material
530A,
530B. It is contemplated that the two rolls will be distinct materials, such as, e.g.,
plastic wrap and aluminum foil. As illustrated in FIG. 31, two separate cutter assemblies
560A,
560B are provided within the recess
536 in the box top
516. The distinct web materials 530A,
530B extend out of the slot
528 and across a corresponding cutter
560A, 560B.
[0096] Each cutter assembly
560A, 560B as illustrated is in the form shown in FIG. 32. The rail portion
562 includes a base
564, two angled side portions
566 and a top
568, defining a slot
570. A sliding cutter
572 is provided and includes a flat portion
574, a neck portion
576 supporting one or more cutter blades, and an actuation head
578, similar to those items found in the cutter assemblies of the above discussed embodiments.
[0097] The form of the central recess as illustrated includes angled walls. However, the
recess may include 90° walls, such as that contemplated by the embodiment of FIG.
1. A corresponding adjustment of the cutter assembly may be desired, incorporating,
e.g., the rail profiles of FIGS. 3-5. Adjustment of the form of the box to create
the varying forms for the recess are contemplated to be within the skill of the art.
[0098] One reason for the provision of the two cutter assemblies relates to the two distinct
material rolls. If, e.g., a plastic or cling wrap is provided on roll
532A, certain cling, static cling or tack construction may be desirable on the edges of
the track to hold the material in place during cutting. However, if aluminum foil,
e.g., is provided on the alternate roll
532B, the rail properties may be required to be different or a different cutter assembly
may be desirable.
[0099] Further variations of the container
510 may be desired to meet the needs of the user. One example is the provision of a flap
or cover that protects the cutter assemblies as is discussed above.
[0100] Referring now to FIGS. 33 and 34, a further form of container
610 is shown in cross section. The container comprises a box
612 having end walls
614 (only the far end wall shown in FIG. 33), a front wall
616, a bottom wall
618, a back wall
620 and a lid
622. Each of the walls is positioned orthogonal to an adjacent wall and together generally
define an interior space. The lid portion
622 comprises a top wall
624, a flap
626 and a tab
628. Web material
630 is preferably stored in a roll
632 and positioned within the inside space defined by the walls of the box
612. The lid
622 is hingedly secured to the top edge of the back wall
620. When the lid
622 is closed, the top wall
624 covers the upper portions of the box
612 between the back wall
620 and the front wall
616. The flap
626 overlies the front wall
616, with the tab
628 overlying a lower part of the front wall.
[0101] A cutter rail
636 extends substantially the length of the box
612. As shown in FIG. 34, the cutter rail
636 comprises a rail portion in the form of a channel
638 of generally rectangular cross section. The rail channel includes a base
640, two side walls
642 and a top
644, defining a slot
646. A sliding cutter
648 (see FIG. 33) is provided inside the channel
638 and includes a foot
650 (captive inside the channel
638), a neck portion
652 supporting one or more cutter blades and extending through the slot
646, and an actuation head
654. The sliding cutter is contemplated to be similar in form to those cutter assemblies
discussed above.
[0102] Two fins
656 project from the base
640 of the rail portion
638, opposite the slot
646. The fins
656 may extend the length of the rail
638, or may be shorter at the ends. The fins
656 may also have gaps along the length of the rail. The fins are parallel to one another
and are spaced to define a gap
658. As illustrated, ribs
660 project from the fins
656 into the gap
658. The ribs
660 extend along the length of the fins and are preferably triangular in cross-section.
The ribs
660 may have any asymmetrically shape and their projecting tips
662 preferably are angled towards the upper portion of the rail. As shown in FIG. 34,
there are several ribs
660 on each of the fins
656, and the ribs alternate within the gap
658. The width of the gap
658 and the dimension and stiffness of the ribs
660 are chosen, in relation to the thickness and material of the front wall
616 of the box
612, so that the front wall
616 can be pushed into the gap
658 without requiring a force that might crumple the box material, but which form a restriction
to removal. Preferably, the tips of the ribs
660 deflect, and/or the material of the front wall
616 compresses or bends slightly, to permit the passage of the front wall into the gap
658. However, if a force is applied tending to withdraw the rail
636, the ribs
660 act as barbs, to grip the front wall and resist removal. If the box
612 is made of paperboard, cardboard or similarly semi-flexible (or compressible) material,
the ribs
660 may bite into the surface of the box material. Alternatively, an adhesive may be
provided or some other securing method.
[0103] As shown in FIG. 33, the lip on the front wall
616 of the box
612 defines is relatively lower than the upper edge of the rear wall
620 and/or the end walls
614, so that when the front wall
616 is fully pushed into the gap
658 between the fins
656, the top of the actuation head
654 of the sliding cutter
648 is just below the top edges of the box ends
614. In this position, the box ends
614 may act as end stops, preventing the sliding cutter
648 from sliding out of the ends of the channel
638 of the cutter rail
636. The top
624 of the lid
622 is made slightly longer than the box ends
614, so that with the lid closed the flap
626 folds down in front of the cutter rail
636.
[0104] To assemble the container
610, the box
612 is formed and the roll
632 of web material
630 is placed in the box. The sliding cutter
648 is inserted in the rail portion
638 from one end, and the cutter rail
636 is pushed onto the box front wall
616. The lid
622 is closed over the cutter rail
636, and the tab
628 is secured to the lower part of the front wall
616, for example, by adhesive. The combination, thus, forms a compact sealed package,
suitable for storage, shipping and display.
[0105] To open the container
610, the user may separate the flap
626 from the tab
628, or separate the tab
628 from the front wall
616. The separation may be irreversible, so that the container
610 can be re-closed loosely, but it is clear that the container has been opened and
re-closed.
[0106] In use, the sheet material
630 is led off the roll
632 across the top surface
644 of the cutter rail
636, where it can be cut by the sliding cutter
648. Because the cutter rail
636 is centered over the box front wall
616, there is little tendency for the cutter rail
636 to tilt sideways and bend the box wall
616 if the user applies excess pressure to the cutter rail
636 or to the sliding cutter
648. The cutter rail
636 preferably overhangs the interior of the box
612 only slightly. Thus, the actuation head
654 does not overhang beyond the side walls
642 of the rail portion
638 and there is little risk of the roll
632 becoming entangled with the cutter assembly if the roll shifts out of position within
the box.
[0107] The box portions of each embodiment discussed above may be made of paper, paperboard,
cardboard, or the like. The boxes alternatively can be made from another substantially
rigid material, such as, for example, plastic. The box could be made from two plies
of 12 point or thinner material. It is contemplated that a thicker box construction
would be more expensive to manufacture but would allow for the container to be reusable,
whereas a thinner box construction would be less expensive to manufacture but would
be more suitable for merely a one-time-use (or disposable) container. A reusable container
may require more durable cutter blades than a disposable container. A metal cutter
blade may be used, especially for a reusable container. A plastic blade may be more
suitable for a disposable container.
[0108] Although elongate square and triangular dispensers have been described, the dispenser
may be of any shape, provided that is capable of accepting a hollow core of web material
and has surfaces and/or corners on which the slot for the web material and the rail
and cutter assembly can be arranged. Thus, at a minimum, the dispenser must include
a space capable of housing the web material. The dispenser may be circular in cross
section. The dispenser can also be semi-cylindrical, rectangular, oval or some other
geometrical or non-geometrical shape. As is shown for the triangular dispenser
110 in FIG. 6, terms such as "square" and "triangular" are not limited to the strict
geometric shape, but include approximations thereto, whether arising from manufacturing
tolerances and imprecision or from deliberate design choices such as the rounded corners
shown in FIG. 6. The web of material could be in some form other than a roll. For
example, the web of material may be folded back and forth on itself. If the web of
material is in a form other than a roll, then the shape of the dispenser is not constrained
to shapes that can efficiently contain a roll.
[0109] Various forms of slot have been described. In many cases, one form of slot may be
substituted for another form, or a slot formed in the box of the container may be
exchanged with a slot formed in the cutter rail, especially in those forms of cutter
rail that extend from the actual cutter guide to engage a box side that is not continuous
behind the cutter rail. The choice of slot may depend on whether it will be covered
by a lid, cap, wrapper or the like. A slot that is closed until the container is brought
into use as a dispenser, and is then opened, for example, by raising a flap or tearing
out a strip, may be appropriate if the slot is not covered. In those drawings where
a slot not shown or particularly mentioned, a suitable slot form is contemplated and
may take the form of any of the other embodiments.
[0110] If the container is intended to be reusable, a lid or flap that can be opened and
re-closed to insert a new supply of web material into the container may be desired.
In those embodiments where such a flap is not shown, a flap may be provided on a convenient
part of the box, for example, on a side not shown in the partial sections such as
FIG. 27. Where the container is intended to be disposable, a flap may still be provided,
to provide access to the interior to assist in initially feeding the web material
through the slot. Alternatively, the container may be shipped with the free end of
the web material already extending out through the slot, and secured on the outside
of the box, especially if that part of the outside of the box is covered by a lid,
etc.
[0111] Various embodiments show a rail mounted in a recess in the box with the ends of the
rail received under an overhang, etc. at the ends of the box. Other embodiments show
the ends of the rail open. In embodiments where the rail in its in use position is
within the outline of the box, the ends of the box without overhangs may alternatively
extend above the surface on which the cutter rail is mounted, and may then act as
end-stops to prevent the cutter sliding out of the end of the rail. Alternatively,
or in addition, the ends of the cutter rail may be closed by caps, or by deforming
the rail, to retain the cutter within the rail. Alternatively, one or both ends of
the rail may be left open.
[0112] In the embodiments, strips of cling, static cling, or tacky material may be provided
to steady the web material while the material is being cut, and/or to retain the end
of the material until it is drawn forward to cut a next length. For thick webs, and/or
for web materials that do not cling strongly to the cling strips or other retentive
materials, an entire side of the box may be coated with cling or other retentive material.
The strip of the surface over which the underside of the cutter head actually passes
may be left uncoated.
[0113] In the embodiments, the cutter rail is shown as a channel of C-shaped cross section,
with a lengthwise slot, and with the web material being cut resting on the exterior
surfaces either side of the slot. The corresponding cutter has a foot captive inside
the channel, a neck carrying the actual cutter blade passing through the slot, and
a head outside the channel that is grasped by the user. However, other configurations
of cutter rail and cutter may be used.
[0114] Many modifications and other embodiments of the inventions set forth herein will
come to mind to one skilled in the art to which these inventions pertain having the
benefit of the teachings presented in the foregoing descriptions and the associated
drawings. Therefore, it is to be understood that the inventions are not to be limited
to the specific embodiments disclosed and that modifications and other embodiments
are intended to be included within the scope of the appended claims. Although specific
terms are employed herein, they are used in a generic and descriptive sense only and
not for purposes of limitation.
