Description
TECHNICAL FIELD
[0001] The present invention relates generally to a case in which a
roll-type wrapping material used to suppress the diffusion of odor
and maintain freshness and cleanliness when storing a food, a
vegetable, a fruit, or the like in a refrigerator or the like or
carrying a food, a vegetable, a fruit, or the like is packed, and
more specifically to a case having a wrapping material cutting
function, in which the material and configuration of the case are
significantly improved, and thus a wrapping material can be
accurately and conveniently cut off without the use of a separate
cutter.
BACKGROUND ART
[0002] Generally, as wrapping materials used to pack groceries (a
food, a vegetable, a fruit, or the like), there are known a
wrapping film made of synthetic resin, aluminum foil, a kitchen
paper sheet, etc.
[0003] Such a wrapping material is manufactured in the form of a
thin sheet, is wound in the form of a roll, is accommodated inside
a case made of a paper material, and is then sold. A user takes out
a wrapping material (hereinafter referred to as the "sheet"), wound
in the form of a roll, to a desired length, cuts off it, and then
uses it.
[0004] A currently used common case is made of a paper material,
and has a rectangular parallelepiped structure the cover of which
can be selectively opened and closed. Furthermore, a metallic
cutter with a serrated cutting edge is fastened onto one side of
the case, and thus a user opens the cover, takes out a sheet by
pulling the sheet by a required length, brings the sheet into
contact with the cutting edge of the cutter, and then pulls the
sheet downward, thereby cutting off the sheet.
[0005] However, since the sheet is cut off by means of the metallic
cutting edge, the case has problems in that a user frequently cuts
his or her hand due to his or her carelessness, in that the sheet
is removed from the case during the cutting of the sheet or the
sheet is moved within the case in the instant of cutting off the
sheet and not cut off along a rectilinear line, etc.
[0006] Accordingly, in order to overcome the above problems, a new
type of case is disclosed in a Japanese unexamined patent
application publication (No. 2003-175488).
[0007] FIGS. 1a and 1b are perspective views showing a conventional
embodiment, and FIG. 2 is a development view of a conventional saw
teeth-equipped dispensing container. In the container, a container
body A and a cover B formed to extend from the container body A and
configured to cover the top opening of the container body A are
composed of a blank P made of, for example, thick paper, a
cardboard, or the like.
[0008] As shown in the development view of FIG. 2, in the blank P,
a front part A1, a bottom part A2, a back part A3, and left and
right side parts A4 constituting the container body A are
successively formed via fold lines, and an upper cover part B1, a
front cover part B2, and left and right cover part B3 constituting
the cover B are successively formed via fold lines.
[0009] A cutoff portion B4 extends from the front end of the front
cover part B2 with a saw-toothed cutting line 1 disposed
therebetween, and the saw-toothed cutting line 1 is punched along
with nicks 3 to be described later during the cutting of the blank
P.
[0010] Furthermore, in the middle of the saw-toothed cutting line
1, a plurality of saw teeth 3 each larger than each peak-shaped
edge 2a of the saw teeth 2 is installed, the blank P can be folded
and bent by the nick 3a . . . formed at the front ends of the saw
teeth 3 . . . , and the nicks 3a . . . of the saw teeth 3 . . .
protrude from any one of the cutting surfaces 1a and 1b of the
saw-toothed cutting line 1 to the other one.
[0011] Although the shape of each of the saw teeth 3 . . . is shown
as a peak larger than each peak-shaped edge of the saw teeth 2 in
the case of the illustrated example, the shape is not limited
thereto, and the shape may be, for example, another shape, such as
an approximately semicircular shape or the like.
[0012] Furthermore, in the process of manufacturing the saw
teeth-equipped dispensing container, both cutting surfaces 1a and
1b of the saw-toothed cutting line 1 are exposed in a two-layer
stepped form by folding and superimposing the blank P around both
cutting surfaces 1a and 1b of the saw-toothed cutting line 1 and
the nicks 3a . . . of the saw teeth 3 . . . , and the curable resin
R is applied to the exposed portion and cured in the state in which
both cutting surfaces 1a and 1b of the saw-toothed cutting line 1
have been exposed.
[0013] In the case of the present embodiment, as shown in FIGS. 1a
and 1b, the cutting surface 1a of the saw-toothed cutting line 1 on
a cutoff portion B4 side and the cutting surface 1b of the
saw-toothed cutting line 1 on a cover B side are exposed by turning
and superimposing the front cover part B2 and cutoff portion B4 of
the cover B, and the curable resin R is applied to the exposed both
cutting surfaces 1a and 1b and both surfaces of the adjacent blank
P by means of, for example, a coating means R1, such as a rollers,
a brush, or the like, in a strip shape.
[0014] In greater detail, the nicks 3a . . . of the saw teeth 3 . .
. have been exposed from the cutting surface 1a of the saw-toothed
cutting line 1 on the cutoff portion B4 side to the cutting surface
1b of the saw-toothed cutting line 1 on the cover B side, and the
cutting surface 1b of the saw-toothed cutting line 1 on the cover B
side on which the saw teeth 2 are formed have farther protruded
than the cutting surface 1a of the saw-toothed cutting line 1 on
the cutoff portion B4 side in a two-layer stepped form in the state
in which the cutoff portion B4 and the front cover part B2 of the
cover B have been turned around the nicks.
[0015] Furthermore, the curable resin R is preferably, for example,
ultraviolet-curable resin, such as an acrylic polyester copolymer,
acrylic epoxy copolymer or an acrylic urethane copolymer, or
electron beam (EB)-curable resin in order to reduce curing
time.
[0016] In this case, the applied curable resin is cured by
radiating ultraviolet rays or electron beams thereon.
[0017] Next, the operation of the saw teeth-equipped dispensing
container is descried.
[0018] First, as shown in FIGS. 1a and 1b, the front cover part B2
and cutoff portion B4 of the cover B are turned and superimposed on
each other around both cutting surfaces 1a and 1b of the
saw-toothed cutting line 1 and the nicks 3a . . . of the saw teeth
3 . . . .
[0019] Accordingly, the cutting surface 1a of the saw-toothed
cutting line 1 on the cutoff portion B4 side and the cutting
surface 1b of the saw-toothed cutting line 1 on the cover B side
are exposed.
[0020] Furthermore, when the curable resin R is applied to both the
cutting surfaces 1a and 1b of the exposed saw-toothed cutting line
1 and both surfaces of the adjacent blank P by the coating means R1
in a strip shape, the curable resin R permeates throughout the
cutting surfaces 1a and 1b of the saw-toothed cutting line 1.
[0021] As a result, the front end surfaces of the saw teeth 2 are
reliably cured using even a simple resin coating method.
[0022] Furthermore, the curable resin R is applied in the state in
which the cutting surface 1b of the saw-toothed cutting line 1 on
the cover B side on which the saw teeth 2 are formed have farther
protruded than the cutting surface 1a of the saw-toothed cutting
line 1 on the cutoff portion B4 side in a two-layer stepped
form.
[0023] Therefore, the curable resin R permeates throughout the
cutting surfaces 1b of the saw teeth 2 and both surfaces of the
adjacent blank P, and thus the overall front end of the saw teeth 2
can be reliably cured.

DISCLOSURE
Technical Problem
[0028] However, in the conventional case having the above-described
structure, curable resin is applied to a corresponding exposed
portion in the state in which the blank has been folded and
superimposed around the saw-toothed cutting line and the nicks of
the saw teeth and both cutting surfaces of the saw-toothed cutting
line have been exposed in a stepped form. Accordingly, although the
conventional case has the advantage of reliably curing the front
end surfaces of the saw teeth, the following various problems
occur.
[0029] First, although the curable resin is applied to both cutting
surfaces of the saw-toothed cutting line in the blank made of a
paper material, there is a limitation on maintaining high strength,
and thus a sheet cannot be cut off along a rectilinear line.
[0030] Second, when the blank is deformed due to carelessness
during distribution or storage, the cutter loses a cutter function,
and thus cannot cut off a sheet.
[0031] Third, the cutter is formed by applying curable resin to the
surface of paper, and thus a relatively thin sheet, such as a
warping material or foil, can be cut off with the cutter but a
paper sheet cannot be cut off with the cutter.
[0032] Fourth, the cutter is formed by applying curable resin to
the surface of paper, and thus the durability of the cutter is
degraded, with the result that the case cannot be repeatedly
used.
[0033] Fifth, after the sheet accommodated in the body has been cut
off, the sheet can be successively taken out only when the front
cover part is raised, and thus the use of the container is
inconvenient.
[0034] The present invention has been contrived to overcome the
above problems, and an object of the present invention is to make a
case out of synthetic resin and form cutting protrusions having
durability along a bend line constituting part of a body in an
integrated manner, thereby enabling the case to be repeatedly used
and also enabling a sheet to be always cut off along a rectilinear
line.
[0035] Another object of the present invention is to form
accommodation spaces in the cover and inward bend portions of a
body and form a moving portion movable within the range of the
accommodation spaces in a front panel, thereby enabling a sheet to
be continuously taken out from the body and to be cut off without
repeatedly opening and closing a cover.
Technical Solution
[0036] In order to accomplish the above objects, according to an
aspect of the present invention provides, there is provided a case
having a wrapping material cutting function, in which a body
includes a front panel, a bottom panel, a back panel, a cover, and
a plurality of side panels, wherein the body is made of a synthetic
resin material, and wherein cutting protrusions are kept spaced
apart from each other and successively formed to protrude upward by
connection portions along a bend line, i.e., a bend line between
the front panel constituting part of the body and an adjacent
inward bend portion, so that a wrapping material accommodated in
the body is cut off by the cutting protrusions protruding upward
along the bend line.
Advantageous Effects
[0037] The present invention has the following various advantages
over the conventional case.
[0038] First, the cutting protrusions performing a cutter function
are made of a synthetic resin material and the case accommodating a
sheet completely maintains a rectangular parallelepiped shape, as
shown in FIG. 4, and thus the bend line along which the cutting
protrusions are formed always maintains a rectilinear state, with
the result that the shape of the bend line is not changed even when
the sheet is cut off using strong force, thereby enabling the sheet
to be always cut off along a rectilinear line.
[0039] Second, the case is made of a rigid synthetic resin material
and assumes a complete rectangular parallelepiped shape, and thus
the case is not easily deformed even when external force is applied
to the case during distribution or storage.
[0040] Third, the cutting protrusions performing a cutter function
are made of a synthetic resin material, and thus they can easily
cut off not only foil but also a tough paper sheet without
requiring separate post-treatment.
[0041] Fourth, the case is made of a synthetic resin material, and
thus it has desirable durability, with the result that only a sheet
needs to be purchased and the case can be repeatedly used, thus
being economical.
[0042] Fifth, a sheet is stored in the body in the state in which
the cover is closed and is taken out and cut off without opening
the cover, and an advantage arises in that the use of the case is
convenient.
[0043] Sixth, when a sheet is cut off, it is cut off in the state
of pushing the sheet accommodated in the body with a finger, and
thus the sheet can be cut off along a rectilinear line regardless
of the amount of wound sheet.

BEST MODE
[0055] Embodiments of the present invention will be described in
detail below with reference to the accompanying drawings so that
those having ordinary knowledge in the art to which the present
invention pertains can easily practice the present invention. The
present invention may be implemented in various different forms,
and is not limited to the embodiments described herein. It is noted
that the drawings are schematically drawn and are not necessarily
drawn to scale. The relative proportions and ratios of components
in the drawings may be exaggerated or diminished in size for the
sake of clarity and convenience, and such arbitrary dimensions are
merely illustrative and are not limitative. Furthermore, the same
reference symbol is used for the same structure, element or part
shown in two or more drawings in order to represent similar
features.
[0056] FIG. 3 is a development view showing a case according to the
present invention, FIG. 4 is a perspective view showing the case
according to the present invention, and FIG. 5 is an enlarged view
of portion "A." of FIG. 3. The present invention is characterized
in that a body 51 constituting the case is made of a synthetic
resin material unlike the conventional container and cutting
protrusions 52 are formed along a bend line of the body 51 to be
spaced apart and are made to successively protrude upward by
connection portions 53 so that a wrapping material contained in the
body 51 are cut off by the cutting protrusions 52.
[0057] The cutting protrusions 52 are formed by means of a separate
cutter (not shown) along with the bend line by pressing a material
having a predetermined thickness, such as that shown in FIG. 3, and
is made to protrude upward, as shown in FIG. 6, by folding the body
51 along a fold line 54.
[0058] As shown in FIG. 5, the cutting protrusions 52 are formed
throughout the bend line in the state in which one surface of each
of the cutting protrusions 52 is formed in the shape of a vertical
surface 52a, the other surface thereof is formed in the shape of an
inclined surface 52b, and neighboring ones of the cutting
protrusions 52 are kept spaced apart from each other at
predetermined intervals by the connection portions 53.
[0059] In this case, one surface of each of the cutting protrusions
52 is formed in the shape of the vertical surface 52, and the other
surface thereof is formed in the shape of the inclined surface 52b
inclined at a predetermined angle .theta.. If the angle .theta. of
the inclined surface is equal to or less than 30.degree., the gaps
between the cutting protrusions 52 are narrow, and thus it is
difficult to machine the cutter for forming the protrusions 52 by
means of a tool. If the angle .theta. of the inclined surface is
greater than 40.degree., the intervals between the cutting
protrusions 52 are excessively long, and thus the performance of
cutting a sheet 55 is degraded. Accordingly, the inclined surface
52b is preferably formed to be inclined at an angle in the range
from 30 to 40.degree..
[0060] Although the location where the cutting protrusions 52 are
formed may be set to a first bend line or a second bend line as
desired, the cutting protrusions 52 are formed through the first
bend line, i.e., a bend line between an inward bend portion 56 and
a front panel 57, as shown in FIG. 4 in which an embodiment of the
present invention is illustrated.
[0061] The protruding height of the cutting protrusions 52 is set
to a value in the range from 1.5 to 2.0 mm in an embodiment of the
present invention. If the protruding height is equal to or less
than 1.5 mm, the pitch is excessively narrow, and thus the
performance of cutting the sheet 55 is degraded. In contrast, if
the protruding height is equal to or greater than 2.0 mm, the pitch
is excessively wide, and thus a cut surface becomes rough.
[0062] When the material of the body 51 is polypropylene (PP) or
polyethylene terephthalate (PET) harmless to humans and the
thickness of the body 51 ranges from 0.4 to 0.45 mm, it may be
possible to minimize the amount of material used while maintaining
the durability of the cutting protrusions 52, thus being
economical.
[0063] The case according to the present invention is configured
such that the inward bend portion 56 extends from the front panel
57 and thus part of a top opened by a cover 58 is closed by the
inward bend portion 56, as shown in FIG. 3.
[0064] In this case, when a downward bend portion 56a is formed in
the inward bend portion 56, the downward bend portion 56a pushes
the sheet 55 taken out from the body 51, as shown in FIG. 7, and
thus the advantage of cutting the sheet 55 with the cutting
protrusions 52 while more stably taking out the sheet 55 is
achieved.
[0065] A first side panel 59 having first and second auxiliary side
panels 60 and 61 is formed at each of both opposite side ends of
the body 51, and a stop hole 59a is formed in the first side panel
59.
[0066] Furthermore, a second side panel 62 is formed at each of
both opposite side ends of the inward bend portion 56, and a third
auxiliary side panel 66 is bendably formed in the second side panel
62. In this case, an embossing protrusion 66a protrudes from the
third auxiliary side panel 66.
[0067] Furthermore, a fastening portion 63 having an elastic
portion 63a to be caught in the stop hole 59a formed in the first
side panel 59 so that the body 51 forms a rectangular
parallelepiped shape is formed at each of both opposite side ends
of the cover 58.
[0068] Accordingly, as shown in FIG. 9, when the first, second and
third auxiliary side panels 60, 61 and 66 are bent at 90.degree.
along the fold lines 54 of the first and second side panels 59 and
62, the front panel 57 and a bottom panel 65 are bent at 90.degree.
along the fold line 54, and the third auxiliary side panel 66 is
located over the second auxiliary side panel 66, the second side
panel 62 is automatically located on the inner surface of the first
side panel 59.
[0069] In this state, when the first auxiliary side panel 60 is
brought into tight contact with the inner surface of the second
side panel 62, the lower end of the first auxiliary side panel 60
is caught and supported on the embossing protrusion 66a formed on
the third auxiliary side panel 66, and thus a box having an open
back is formed by the inward bend portion 56, the front panel 57,
and the bottom panel 65.
[0070] Thereafter, when the sheet 55 is put into the inner space of
the body 51, the back panel 64 and the cover 58 are closed in the
state in which one end of the sheet 55 is exposed out of the box,
and the elastic portion 63a formed in the fastening panel 63 is
fitted into the stop hole 59a formed in the first side panel 59,
the assembly of the case of the present invention is completed, as
shown in FIG. 4. Meanwhile, accommodation spaces 67a and 67b are
formed at the centers of the cover 58 and the inward bend portion
constituting the body 51 to be superimposed on each other, and a
moving portion 68 movable within the range of the accommodation
spaces 67a and 67b is formed in the front panel 57.
[0071] In this case, it is preferred that the width b1 of the
accommodation space 67b formed in the inward bend portion 56 is
larger than the width b2 of the moving portion 68. The reason for
this is to allow the moving portion 68 to be freely moved into the
accommodation space 67b when the moving portion 68 is pushed.
[0072] Furthermore, the moving portion 68 has a shape in which the
upper portion thereof is wider than the lower portion thereof, and
through holes 69 are formed at the lower ends of the moving portion
68. The reason for this is to prevent a phenomenon in which the
lower ends of the moving portion 68 are cut (torn) even when the
moving portion 68 is repeatedly pushed.
[0073] In FIG. 3, the lines indicated by solid lines are cutting
lines 70, and the lines indicated by dotted lines are fold lines
54.
[0074] The operation of the present invention configured as
described above is as follows.
[0075] First, when a sheet-shaped synthetic resin material, such as
that shown in FIG. 3, is pressed, the sheet is cut into a
predetermined shape along the cutting lines 70, pressing is
performed along the fold lines 54, and the cutting protrusions 52
are formed throughout the bend line, i.e., the bend line between
the inward bend portion 56 and the front panel 57, by means of the
separate cutter (not shown) at the same time.
[0076] After the pressing, the cover 58, the back panel 64, the
bottom panel 65, the front panel 57, the inward bend portion 56,
and the downward bend portion 56a are sequentially turned along the
fold lines 54 and, simultaneously, the first side panel 59, the
first, second and third auxiliary side panels 60 and 61, the second
side panel 62, the third auxiliary side panel 66, and the fastening
portion 63 are turned along other fold lines 54.
[0077] Thereafter, the second auxiliary side panel 61 turned to
90.degree. from the first side panel 59 along the fold line 54 is
brought into tight contact with the inner surface of the front
panel 57, the inward bend portion 56 is turned, the third auxiliary
side panel 66 turned to 90.degree. from the second side panel 62 is
brought into tight contact with the second auxiliary side panel 61,
and then the first auxiliary side panel 60 is brought into tight
contact with the second side panel 62, thereby allowing the lower
end of the first auxiliary side panel 60 to be caught on the
embossing protrusion 66a. This assembly operation is performed on
both opposite sides of the body 51 in the same manner.
[0078] When the first and second side panels 59 and 62 and the
first, second and third auxiliary side panels 60, 61 and 66 are
set, as described above, a box having an open back is formed by the
inward bend portion 56, the front panel 57 and the bottom panel 65.
A sheet 585 to be used is put into the inside of the box, the back
panel 64 and the cover 58 are closed in the state in which one end
of the sheet 585 is exposed out of the box, and then the elastic
portion 63a formed in the fastening portion 63 is fitted into the
stop hole 59a formed in the first side panel 59, thereby completing
the assembly of a container box.
[0079] In this state, when it is necessary to cut off the sheet 55
accommodated inside the body 51, the sheet is taken out to a
required length. In this case, the downward bend portion 56a of the
inward bend portion 56 is in tight contact with the outer
circumferential surface of the sheet 55, and thus the sheet 55 is
stably taken out.
[0080] Once the sheet 55 has been taken out to a desired length,
the cover 58 is pushed with one hand and the sheet 55 is held and
pushed downward by the other hand, with the result that the sheet
55 is clearly cut off along a single rectilinear line by the
cutting protrusions 52 made of a synthetic resin material and
formed along the bend line.
[0081] After the sheet 55 has been taken out from the body 51 to a
required length and cut off, the remaining sheet 55 is accommodated
inside the body 51 by the cover 58 and the downward bend portion
58a, and thus a phenomenon in which the sheet 55 is contaminated
with dust or the like can be prevented.
[0082] Meanwhile, when it is necessary to take out and cut off the
sheet 55 accommodated in the body 51, the moving portion 68 is
pushed inward in the direction indicated by the lower arrow in the
form indicated by the alternate short and long dotted lines so that
the moving portion 68 is accommodated in the accommodation spaces
67a and 67b, as shown in FIG. 10, and thus the sheet 55 can be
taken out to a desired length without opening the cover 58 by
holding portion "K" of the sheet 55 accommodated inside the body 51
and pulling the portion "K" in the direction indicated by the upper
arrow.
