Technical Field
[0001] The present invention relates to a packing box suitable for a packing photosensitive
recording material such as an X-ray film and, more specifically, a packing box for
photosensitive recording material in which an opening port can be formed adjacently
to an output port for facilitating the photosensitive recording material to be taken
out from the output port.
Background Art
[0002] In order to facilitate the photosensitive recording material such as the X-ray film
to be taken out from the packing box, there is a type in which an opening port 103
can be formed adjacently to an output port 101 as shown in Fig. 6A and Fig.6B in the
related art.
[0003] The type shown in Fig. 6A is formed with a lateral zipper 105 in parallel with the
output port 101 at a position about 10 cm from the output port 101 and, when in use,
the lateral zipper 105 is torn and then an opening strip 107 is pulled upward from
below to enable the opening port 103 to be opened (see
JP-A-8-114889).
[0004] The type shown in Fig. 6B is formed with perforated lines 111 respectively at both
ends of an upper portion of a front panel 109 which is adjacent to the output port
101 in the direction vertical to the output port 101 and, when in use, an opening
tape 113 is torn first, and then the opening strip 107 is pulled downward from the
top to enable the opening port 103 to be opened.
[0005] However, in the case of the former type, since the lateral zipper 105 is long, the
large amount of paper powder is generated. When a light-shielding moisture proof bag
for storing the photosensitive recording material is electrically charged, the generated
paper powder is attached thereto, and is carried into a tray of an imager. When the
paper powder is attached to an unexposed film when being mounted to a daylight room,
a defect called "blank" may result.
[0006] In the case of the latter type, since the perforated lines 111 also serve as bending
lines, if the length of portions to be broken of the perforated lines 111 is too short,
the perforated lines may be broken when forming a box or the compression strength
is lowered. In contrast, if the length of portions to be broken of the perforated
lines 111 is too long, a large opening force is required. In particular, in the case
of a wide box, since the distance between the perforated lines 111 is large, it may
not be opened successfully unless it is opened in parallel with the perforated lines
111 using both hands.
Disclosure of the Invention
[0007] In view of above-described problems of the packing box in the related art, it is
an object of the invention to provide a packing box for photosensitive recording material
in which an opening port can be formed easily by pulling an opening strip with one
hand and the amount of generation of paper powder at this time is small.
[0008] After having repeated keen examination, the inventor found that the above-described
problem can be solved according to the packing box for photosensitive recording material
in the invention having a configuration shown below.
[0009] A packing box for photosensitive recording material according to the invention includes
a box body of a rectangular shape in cross-section for storing a photosensitive recording
material, and a lid portion having a lid top plate and an insertion flap for enabling
opening and closing of an output port for the photosensitive recording material and
being formed integrally with the box body, wherein two perforated lines including
cut portions and non-cut portions arranged alternately are formed from two points
at a distance of 50 to 75% of an entire width of the output port toward a bottom portion
of the box body so as to approach toward each other at the same angle between 60°
and 90°, preferably, between 70° and 80° with respect to an upper side of a front
panel on the side of the output port of the front panel of the box body to which the
insertion flap comes adjacent when the lid portion is closed, wherein an area surrounded
by the two perforated lines and lines connecting between upper ends and between lower
ends of the respective perforated lines constitutes a substantially trapezoidal opening
strip for forming an opening port for facilitating the photosensitive recording material
to be taken out from the output port when the respective perforated lines are broken,
wherein the cut portions of the perforated line each include a main line extending
in a breaking direction and an introduction line formed so as to open at a starting
side of the respective cut portions outward from the breaking direction, and wherein
the respective cut portions are arranged such that when an imaginary line vertical
to the upper side of the front panel is drawn from a terminal of the main line to
the cut portion located immediately below, the imaginary line passes through a center
area of the introduction line out of three equally divided parts of the cut portion
immediately below (first mode) .
[0010] In the invention shown above, the packing box for photosensitive recording material
is formed of a corrugated board (second mode).
[0011] In the invention described above, flutes of the corrugated board are formed in parallel
with the upper side of the front panel, and the positions of the corresponding cut
portions of the two perforated lines may be shifted in the vertical direction toward
the upper side of the front panel by an amount corresponding to one third to two third,
more preferably, a half a pitch of the flutes of the corrugated board (third mode).
[0012] In the invention described above, the length of the non-cut portion of the respective
perforated lines may be reduced on the side closer to an upper side of the output
port and increased on the side closer to a bottom portion thereof (fourth mode).
[0013] In the invention described above, beginning ends of the two perforated lines located
on the upper side of the front panel are rounded sides thereof (fifth mode).
[0014] In the invention described above, the upper side of the front panel is cut into fine
waveforms (sixth mode)
[0015] In the invention described above, lines are tooled from a surface opposite from a
printed surface of the packing box for photosensitive recording material and the box
is formed by valley bending the lines (seventh mode).
[0016] According to the first mode, since a sufficient force for breaking the non-cut portions
of the perforated lines is efficiently applied to the two perforated lines only by
pinching a point at a center of the opening strip and pulling the same downward with
fingers, the two perforated lines can be broken easily with one hand. Since the total
length of the two perforated lines is relatively short, the amount of generation of
paper powder at the time of breakage can be suppressed.
[0017] According to the second mode, the packing box for photosensitive recording material
superior in strength and light-shielding property can be provided.
[0018] According to the third mode, since the portions which can easily be broken and the
portions which can hardly be broken of the two perforated lines on the corrugated
board are broken in the equalized manner, variations in an opening force can be reduced.
[0019] According to the fourth mode, since the length of the non-cut portion of the respective
perforated lines is short on the side closer to the output port and long on the side
closer to the bottom portion, the perforated lines which can be cut easily at the
beginning of cutting, and can be cut straight to the end when it is started to be
cut once are realized.
[0020] According to the fifth mode, an operator is prevented from being injured on his/her
hand by a pointed edge when he/she opens the opening strip.
[0021] According to the sixth mode, the operator is prevented from being injured on his/her
hand by a cut edge of the corrugated board.
[0022] According to the seventh mode, variation in box dimension and abnormalities such
as clog of products or faulty insertion of the insertion flap in an automatic filling
machine can be prevented when forming the packing box by bending along the lines.

Detailed Description of the Invention
[0024] Referring now to the drawings, a packing box for photosensitive recording material
according to the present invention will be described in detail.
[0025] Fig. 1 is a perspective view showing an entire packing box for photosensitive recording
material (hereinafter referred to as packing box) to which the present invention is
applied in the closed state; Fig. 2A is an extension plan view of the packing box
of a side opening type and Fig. 2B is an extension plan view of the packing box of
a vertically opening type; Fig. 3A is an enlarged drawing of a periphery of an opening
strip in the closed state and Fig. 3B is an enlarged drawing of the periphery of the
opening strip in the opened state; Figs. 4A and B illustrate enlarged drawings of
a perforated line; and Fig. 5 is an explanatory drawing showing a state in which the
left and right perforated lines are shifted in the vertical direction. In the following
description, upper, lower, left and right of the packing box are based on a packing
box 1 in Fig. 1.
[0026] The packing box 1 in the present invention mainly includes a box body 5 that accommodates
a photosensitive recording material M tight-sealed in an inner bag 3 and has a rectangular
shape in cross-section having a longitudinal side and a short side. The box body 5
is formed at an upper portion thereof with an output port 7 for the photosensitive
recording material M in the opened state, and is closed by a lid portion 9 which can
be opened and closed in the closed state. The lid portion 9 includes a lid top plate
11 and an insertion flap 13 continuing therefrom formed integrally with the box body
5. For example, the packing box 1 is formed by assembling an extension plan view 15
of a side opening type as shown in Fig. 2A or an extension plan view 15 of a vertically
opening type as shown in Fig. 2B. A chain line represents a valley fold line, a chain
double-dashed line represents a mountain fold line, and a solid line in the extension
plan view represents a breaking line in Fig. 2A and Fig. 2B. The packing box 1 is
formed of micro-flute corrugated board such as E-flute (the number of corrugation
is about 94/300 mm) or F-flute (the number of corrugation is about 120/300 mm), and
the flutes extend in the direction designated by reference numeral 17 in Fig. 2A and
Fig. 2B, that is, the flutes extends in parallel with an upper side of a front panel
21 described later, and the direction designated by reference numeral 19 corresponds
to the direction of paper grain of a liner.
[0027] As shown in Fig. 1, a plane of the box body 5 on the side where the insertion flap
13 comes adjacent thereto when the lid portion 9 is closed is a front panel 21, and
a back panel 23 is provided so as to oppose the front panel 21. Side panels 25 are
provided at both ends between the front panel 21 and the back panel 23, and a bottom
panel 27 is provided at a bottom of the box body 5.
[0028] Two perforated lines 31, 33 are formed on the side of the output port 7 of the front
panel 21 from two points at a distance of 50 to 75% of an entire width 29 of the output
port 7 toward a bottom surface of the box body 5. The two perforated lines 31, 33
are formed at a slant so as to approach toward each other at the same angle α between
60° and 90°, preferably, between 70° and 80° with respect to an upper side 35 of the
front panel 21. The angle in this embodiment employs 75°.
[0029] In this embodiment, the perforated lines 31, 33 each are configured by a combination
of six sets of cut portions 37 and non-cut portions 39 arranged alternately. A substantially
trapezoidal area surrounded by the two perforated lines 31, 33, the upper side 35
and a hinge 40 of the mountain fold constitute an opening strip 41, so that an opening
port 43 is formed by opening the opening strip 41 when the respective perforated lines
31, 33 are broken thereby facilitating the photosensitive recording material M to
be taken out from the output port 7. A notched portion 55 is formed at a center of
the upper side 35 of the front panel 21 for facilitating a finger to hold the insertion
flap 13 when opening the lid portion 9.
[0030] The cut portions 37 of the respective perforated lines 31, 33 each include a main
line 45 extending in a breading direction 44 shown in Figs. 4A, 4B and introduction
lines 47 each formed so as to open at a starting side of the respective perforated
lines 31, 33 (the side closer to the output port 7) outward from the breaking direction.
The positional relation between the respective adjacent cut portions 37 is, as shown
in Figs. 4A, 4B, such that when an imaginary line 59 vertical to the upper side 35
of the front panel 21 is drawn from a terminal (an end closer to the bottom panel
27) of the main line 45 of the cut portion 37 located on an upper side to the introduction
line 47 immediately below, the vertical line passes through a center area 49 of the
introduction line 47 out of three equally divided parts thereof.
[0031] The length of the non-cut portion 39 of the respective perforated lines 31, 33 (i.e.
the length of the imaginary line 59) may be all the same as shown in Fig. 4A or may
be such that the length of the non-cut portion 39 is reduced on the side closer to
an upper side of the output port 7 and of a non-cut portion 39' is increased on the
side closer to a bottom portion thereof as shown in Fig. 4B. For example, in a case
in which six pairs of the cut portion 37 and the non-cut portion 39 are provided as
in the embodiment shown in Fig. 4B, it is also possible to set the length of the three
non-cut portions 39 located closer to the output port 7 to 3 mm, and the length of
the remaining non-cut portions 39' to 3.5 mm or, although not shown, to employ a configuration
in which the length of the non-cut portions 39 is increased gradually in sequence
from the side closer to the output port 7.
[0032] The operation to open the opening strip 41 is none other than the principle of leverage
with the notched portion 55 as a power point, the hinge 40 as a supporting point,
and the non-cut portion 39 as a working point. When it starts to open, since the working
point is located immediately inside the power point, a force applied to the non-cut
portion is not amplified. However, at the end of opening, the working point is moved
to a point immediately outside the supporting point, and hence the non-cut portion
39 can be broken to the end easily only by applying a small force to the power point.
[0033] In the packing box 1, the insertion flap 13 is inserted under the three non-cut portions
39 on the side closer to the output port 7 in the unopened state, even when a load
is applied to the front panel 21 in the vertical direction, or in the case in which
the packing box 1 is roughly treated, the non-cut portions 39 of the perforated lines
31, 33 are prevented from being broken by mistake. Alternatively, even when the length
of the remaining non-cut portions 39' is increased, the force required for the opening
end portion is not increased. In this arrangement, the perforated line which can be
easily cut at the beginning of cutting, can be cut straight to the end when it is
stated to be cut once, and is strong is realized.
[0034] As shown in Fig. 5, the positions of the respective cut potions 37 of the two perforated
lines 31, 33 are shifted in the vertical direction toward the upper side 35 of the
front panel 21 by an amount corresponding to one third to two thirds, more preferably,
a half a pitch 51 of the flutes of the corrugated board. In this configuration, the
portions which can easily be broken and the portions which can hardly be broken of
the two perforated lines 31, 33 on the corrugated board are broken in an equalized
manner, so that variations in an opening force can be reduced.
[0035] Subsequently, the configuration of the portions around the perforated lines 31, 33
will be described. As shown in Fig. 3A, beginning ends 53 of the two perforated lines
31, 33 located on the upper side 35 of the front panel 21 are rounded on both sides
thereof, so that an operator is prevented from being injured by a pointed edge when
opening the opening strip 41. At least all the areas of the upper side 35 of the front
panel 21 including the above-described notched portion 55 are cut into fine waveforms
57 as shown in Figs. 4A, 4B so as to prevent finger cut by a cut edge of the corrugated
board.
[0036] The packing box 1 in the present invention, a back surface of a surface shown in
the extension plan view 15 of Fig. 2A and Fig. 2B is a printed surface, and the lines
shown by the chain line and the chain double-dashed line are tooled from the side
opposite from the printed surface, that is, the side of the surface shown in the extension
plan view 15. Accordingly, when forming the packing box by bending along the line,
variations in box dimension and abnormalities such as clog of products or faulty insertion
of the insertion flap in an automatic filling machine can be prevented.
[0037] The packing box for photosensitive recording material according to the present invention
can be utilized widely as a packing box for packing various types of the photosensitive
recording materials. In particular, it is preferably used as a packing box for an
X-ray film such as medical film in which developing liquid is not used, such as a
laser imager.
