[0004] Description of the Related Art
[0005] A resin container such as a pouch is used as a refill
container or a packing container such as a simplified
container.
[0006] In recent years, an imitation product of a pouch or the like
has been marketed overseas and the like. If such an imitation
product is mass-marketed, large loss may be caused. For this
reason, there is a demand for a means for preventing the
manufacturing of an imitation product at low cost and conveniently.
For example, it is considered to attach a seal like a security mark
that is provided separately from a container onto a container
surface, but if the seal is changed, the seal becomes unhelpful in
forgery prevention.
[0007] Thus, various methods have been proposed for providing
forgery prevention or the like on the container itself.
[0008] Nevertheless, in the technique described in Patent Document
1, as for a pouch on which laser processing is not performed, a
laser emission process is added for forgery prevention, and
manufacturing cost increases.

[0023] The packing container of the present invention is a packing
container for packing content by a sheet, the sheet including a
latent image sheet on which a latent image pattern is formed, and a
visualization sheet on which a visualization pattern is formed, and
in the latent image sheet and the visualization sheet, at least
either one sheet of regions in which the latent image pattern and
the visualization pattern are formed is a transparent sheet, and
internal surfaces of the regions in which the latent image pattern
and the visualization pattern are formed are formed to be able to
contact each other. With this configuration, by bringing the
internal surfaces of these sheets into contact while containing and
storing content in the packing container, and causing the latent
image pattern on the latent image sheet and the visualization
pattern on the visualization sheet to overlap, the latent image
pattern can be clearly displayed so as to be visible. An
authentication portion for forgery prevention can be thereby
provided on each sheet.
[0024] In addition, in the present invention, as the transparent
sheet, it is only required that a region in which the latent image
pattern or the visualization pattern is formed be transparent, and
other regions and the other pattern of one pattern formed on the
transparent sheet can be formed on a nontransparent sheet.
[0025] In the packing container of the present invention, the
latent image sheet and the visualization sheet are laminates each
including a base material and a sealant layer, a seal portion is
formed by sealing rim portions of the latent image sheet and the
visualization sheet so that the sealant layers face each other, and
by providing the latent image pattern and the visualization pattern
at positions separated from the seal portion, the internal surfaces
of the sheets are brought into contact by pushing the laminates
while containing and storing content in the packing container, and
by overlapping the latent image pattern on the latent image sheet
and the visualization pattern on the visualization sheet provided
on unsealed portions, a latent image can be made visible.
[0026] In this case, when content to be stored in the packing
container is liquid, the content is preferably supplied with such
an allowance for overlapping the latent image pattern on the latent
image sheet and the visualization pattern on the visualization
sheet. In addition, while a transparent infill does not interrupt,
when an infill formed of nontransparent liquid, powder, or a small
solid is used as content, it is necessary to prevent portions
corresponding to the latent image pattern on the latent image sheet
and the visualization pattern on the visualization sheet from being
exposed to the content. In addition, if a latent image pattern on a
latent image sheet and a visualization pattern on a visualization
sheet are provided in the vicinity of a seal portion, in some
cases, an overlapping position deviates and a latent image fails to
be visualized and fails to be correctly recognized visually. Thus,
they need to be separated from the seal portion by a predetermined
distance.
[0027] By using the latent image sheet and the visualization sheet
of the present invention as a front surface and a rear surface of a
pouch container, in the pouch container using a transparent sheet,
authentication for forgery prevention or the like can be easily
performed.
[0028] In the present invention, by the latent image pattern being
formed on the latent image sheet by printing, and the visualization
pattern being formed on the visualization sheet by printing, the
latent image pattern and the visualization pattern are formed by
performing printing on the transparent sheet, and only by adjusting
these positions, visualization can be performed and authentication
for forgery prevention or the like can be easily performed.
[0029] In the present invention, the latent image sheet includes a
latent image pattern formed by a latent image formed by a
periodical pattern, and a background formed by a periodical pattern
having a different phase, pitch, or array direction from that of
the latent image, the visualization sheet includes a visualization
pattern formed by a periodical pattern, and by visualizing the
latent image by causing the latent image sheet and the
visualization sheet to overlap each other, authentication for
forgery prevention or the like can be easily performed.
[0030] In the present invention, the latent image sheet has a
latent image pattern having points, lines, dotted lines, or the
like that are formed as a predetermined pattern, as constituent
elements, and a pattern and a background having points, lines,
dotted lines, or the like that have a different size from that of
the latent image pattern, as constituent elements, or has a latent
image pattern and a background having points, lines, dotted lines,
or the like of a certain color phase, as constituent elements, and
a pattern having points, lines, dotted lines, or the like of
another color phase, as constituent elements, and the constituent
elements of the latent image have a regular sequence that is not
included in the constituent elements of the background, the latent
image pattern cannot be visually detected from the background, but
the pattern can be detected, the visualization sheet has the
visualization pattern serving as a pattern corresponding to the
latent image, moire is generated only in a portion of the latent
image pattern by causing the latent image sheet and the
visualization sheet to overlap at an appropriate position and
angle, and the latent image pattern and the background appear
clearly and contrastively, so that authentication for forgery
prevention or the like can be easily performed.
[0031] In the present invention, in the latent image pattern, the
latent image and the background are formed by halftone dots
linearly arrayed at a uniform pitch, pitches of the latent image
and the background shift by 1/4 to 3/4, and the visualization
pattern is formed by hairlines having the same pitch as the latent
image and the background, so that authentication for forgery
prevention or the like can be easily performed.
[0032] In the present invention, in the latent image pattern,
pitches of the latent image and the background shift by 1/2, so
that authentication for forgery prevention or the like can be
easily performed.
[0033] In the present invention, a plurality of sets of the latent
image patterns and a plurality of sets of the visualization
patterns are provided, so that authentication for forgery
prevention or the like can be easily performed.
[0034] According to the above-described aspects of the present
invention, authentication for forgery prevention or the like can be
easily performed only by performing position adjustment of a latent
image pattern and a visualization pattern to perform
visualization.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
First Embodiment
[0055] The first embodiment of a packing container according to the
present invention will be described below based on the
drawings.
[0056] FIG. 1A is a front view illustrating the packing container
in the present embodiment, and FIG. 1B is a cross-sectional view
taken along a line b-b' in FIG. 1A.
[0057] As illustrated in FIGS. 1A and 1B, a packing container 1
according to the present embodiment is a refill container formed by
a laminate including at least a base material 11 and a sealant
layer 12. The refill container has a standing pouch shape obtained
by forming, as two laminates, a main body front surface laminate 2
and a main body rear surface laminate 3, with a sealant layer being
provided on an inner side, forming a bottom tape 4 by bending
another laminate, with the sealant layer being provided on an outer
side, and inserting it between the main body front surface laminate
2 and the main body rear surface laminate 3, and sealing the rim.
In the container having a standing pouch shape, the bottom tape 4
expands. Thus, the container can easily become a large-volume
container.
[0058] As the base material 11 of the laminates 2, 3, and 4, a
vapor-deposited layer is formed by vapor-depositing metal such as
aluminium and stannum, metal oxide such as silica and alumina, and
the like, onto a transparent sheet. In addition, a metal foil film
can be attached to the transparent sheet, and the laminates 2, 3,
and 4 can further include a print layer, an adhesive layer, and the
like.
[0059] As illustrated in FIG. 1B, side seal portions (seal
portions) 22 are provided at both end portions of the main body
front surface laminate 2 and the main body rear surface laminate 3,
and a bottom seal portion (seal portion) 23 is provided at bottom
portions of the main body front surface laminate 2 and the bottom
tape 4, and the main body rear surface laminate 3 and the bottom
tape 4.
[0060] At an upper portion of the front surface laminate 2 and the
rear surface laminate 3, a discharge nozzle 32 for discharging
content is formed together with a filling opening portion 41 and a
discharge nozzle seal portion 24. The leading end of the discharge
nozzle 32 is sealed by the discharge nozzle leading end seal
portion 24, and a discharge port is formed by separating off the
discharge nozzle leading end seal portion 24 from an opening notch
35. A plurality of laser cut lines being parallel to an expected
opening line may be applied to the vicinity of the discharge nozzle
32 and the opening notch 35.
[0061] In the packing container 1 according to the present
embodiment, the main body front surface laminate 2 serving as a
latent image sheet is provided with a latent image pattern region
(latent image pattern) 5 and a display print region 7 as
illustrated in FIG. 1A. The latent image pattern region 5 and the
display print region 7 are each printed using ink. In the packing
container 1, the main body rear surface laminate 3 serving as a
visualization sheet is provided with a visualization pattern region
(visualization pattern) 6 and the display print region 7 as
illustrated in FIG. 1A. The visualization pattern region 6 and the
display print region 7 are each printed using ink.
[0062] In addition, in at least either one of the latent image
sheet 2 and the visualization sheet 3, portions corresponding to
the latent image pattern region 5 and the visualization pattern
region 6 are transparent, but the other portions such as the
display print region 7 and the seal portions 22, 23, and 24 need
not be transparent. In addition, if the latent image sheet 2 in a
predetermined portion of the latent image pattern region 5 is
transparent, the visualization pattern region 6 in a corresponding
portion of the visualization sheet 3 may be transparent, or may be
nontransparent. Alternatively, if the visualization sheet 3 in a
predetermined portion of the visualization pattern region 6 is
transparent, the latent image pattern region 5 in a corresponding
portion of the latent image sheet 2 may be transparent, or may be
nontransparent.
[0063] A pair of the latent image pattern region 5 and the
visualization pattern region 6 forms an authentication set that
makes a latent image visible, by being combined.
[0064] As illustrated in FIG. 1A, when content to be stored in the
packing container 1 is liquid, the content is supplied with such an
allowance for causing the latent image pattern 5 of the latent
image sheet 2 and the visualization pattern 6 of the visualization
sheet 3 to overlap each other. Specifically, as illustrated in FIG.
1A, in a standing (standing position) state, liquid is preferably
supplied into the packing container 1 to about a height indicated
by a filling line W, and the latent image pattern 5 and the
visualization pattern 6 are provided to be located on the upper
position of the filling line W.
[0065] In addition, the packing container 1 such as a pouch has
flexibility. Thus, a filling rate of content is smaller than that
in the above-described state, and the inside of the container has
room. If internal surfaces of the latent image sheet 2 and the
visualization sheet 3 can be brought into contact with each other
or brought closer to each other to a state in which a latent image
is visible, the arrangement of the latent image pattern 5 and the
visualization pattern 6 is not limited to the upper side of the
packing container 1.
[0066] In addition, while a transparent infill does not interrupt,
when an infill formed of nontransparent liquid, powder, or a small
solid is used as content, it is necessary to prevent portions
corresponding to the latent image pattern 5 on the latent image
sheet 2 and the visualization pattern 6 on the visualization sheet
3 from being exposed to the content. In addition, if a latent image
pattern of a latent image sheet and a visualization pattern of a
visualization sheet are provided in the vicinity of a seal portion,
in some cases, an overlapping position deviates, and a latent image
fails to be visualized and fails to be correctly recognized
visually. Thus, they need to be separated from the seal portion by
a predetermined distance (to avoid overlapping the seal
portion).
[0067] In addition, as illustrated in FIG. 1A, the latent image
pattern 5 and the visualization pattern 6 are provided at positions
separated from all of the seal portions 22, 23, and 24 by a certain
distance or more. If the latent image pattern 5 and the
visualization pattern 6 are close to the seal portions 22, 23, and
24, the latent image pattern 5 and the visualization pattern 6 may
deviate from a position where a latent image can be easily
visualized due to the deformation or the like of the sheets 2 and 3
in the formation of the seal, and a latent image may partially fail
to be visualized, which is not preferable.
[0068] The latent image pattern 5 and the visualization pattern 6
form a pair with each other, and a specific latent image pattern 5
corresponds to a specific visualization pattern 6. By causing the
visualization pattern 6 corresponding to the specific latent image
pattern 5 to overlap the specific latent image pattern 5, the
latent image can be visualized, and can be made recognizable. On
the other hand, even if a visualization pattern not corresponding
thereto is caused to overlap, generally, a latent image cannot be
visualized, and cannot be made recognizable. Thus, when the latent
image sheet 2 and the visualization sheet 3 are formed as sheets
forming the front and the rear of the packing container 1, pasting
positions in the latent image sheet 2 and the visualization sheet 3
can be matched, and both sheets can be combined and sealed as an
authentication set.
[0069] In addition, the latent image sheet 2 may be provided with a
latent image pattern over the entire surface. Alternatively, the
latent image sheet 2 may be provided with the latent image pattern
5 on a partial region. In addition, the latent image sheet 2 can be
divided into a plurality of regions, and a latent image pattern can
be provided in each of the plurality of regions. In a similar
manner, the visualization sheet 3 may also be provided with the
visualization pattern 6 on a partial region. In addition, the
visualization sheet 3 may be divided into a plurality of regions,
and the visualization pattern 6 may be provided in each of the
plurality of regions.
[0070] The latent image pattern 5 is formed by a latent image and a
background, and the latent image and the background are each formed
by a periodical pattern. In addition, the visualization pattern 6
is also formed by a periodical pattern.
[0071] In the latent image pattern 5, as a periodical pattern
forming the latent image and the background, for example, hairlines
constituted by a plurality of parallel lines can be used, and a
linear margin part is arranged between a line and a line of the
plurality of parallel lines. The width of the parallel line and the
width of the linear margin part are desirably made the same. In
addition, the latent image and the background are formed so that
the phases, the pitches, or the array directions of the hairlines
become different from each other.
[0072] For example, in the latent image pattern 5, hairlines
forming the latent image can be formed so as to have a pitch
different by 1/4 to 3/4 with respect to the hairlines forming the
background. Furthermore, it is preferable that the hairlines be
formed so as to have a pitch different by 1/2. In this case, the
visualization pattern 6 can be formed by hairlines similar to the
hairlines forming the background. In addition, because the latent
image and the background are relative concepts, the visualization
pattern can be formed by hairlines similar to the hairlines forming
the latent image.
[0073] In addition, hairlines forming the background can be formed
so as to have the same pitch and a phase different by 1/4 to 3/4 of
the pitch with respect to the hairlines forming the latent image.
Furthermore, it is preferable that the hairlines be formed so as to
have a phase different by 1/2. In this case, the visualization
pattern can be formed by hairlines similar to the hairlines forming
the background. In addition, because the latent image and the
background are relative concepts, the visualization pattern can be
formed by hairlines similar to the hairlines forming the latent
image.
[0074] Alternatively, in the latent image pattern 5, the hairlines
forming the latent image can be formed so as to have the double
pitch with respect to the pitch of the hairlines forming the
background. Also in this case, the visualization pattern 6 can be
formed by hairlines similar to the hairlines forming the
background. In addition, the visualization pattern 6 can be formed
by hairlines similar to the hairlines forming the latent image.
[0075] In addition, in the latent image pattern 5, the hairlines
forming the background can be formed so as to have a direction
different by 45 degrees from the direction of the hairlines forming
the latent image. In addition, because the array direction of the
hairlines is a direction perpendicular to the direction of the
hairlines, by making the hairlines forming the latent image and the
hairlines forming the background different by 45 degrees (shifting
by 45 degrees), array directions of the hairlines can be made
different. Also in this case, the visualization pattern 6 can be
formed by hairlines similar to the hairlines forming the
background. In addition, the visualization pattern 6 can be formed
by hairlines similar to the hairlines forming the latent image.
[0076] In addition, in the latent image pattern 5, as a periodical
pattern forming the latent image and the background, in place of
hairlines, linearly arrayed dots can be used. In this case, the
visualization pattern can be formed by dots similar to dots forming
the background. In addition, the visualization pattern 6 can be
formed by hairlines that can overlap the dot line.
[0077] In FIG. 2, FIG. 2(a) is an enlarged schematic diagram
illustrating halftone dots forming an image in the latent image
pattern 5, viewed from the top, FIG. 2(b) is an enlarged schematic
diagram illustrating hairlines forming the visualization pattern 6,
viewed from the top, and FIG. 2(c) is a schematic enlarged diagram
illustrating a state in which the latent image pattern 5 and the
visualization pattern 6 are overlapped.
[0078] As illustrated in FIG. 2(a), the latent image pattern 5 is
formed by a non-latent image portion (background) 5a formed by
halftone dots having a uniform pitch, and a latent image portion 5b
formed by halftone dots having a pitch shifted by about 1/2 pitch
with respect to the non-latent image portion 5a. An image is formed
by assemblies of halftone dots.
[0079] In addition, the latent image portion 5b may have any shape
such as a character, a picture, a symbol, and a pattern, and may be
formed to be visible.
[0080] As illustrated in FIG. 2(b), the visualization pattern 6 is
formed by hairlines 6a having a pitch equal to the pitch in the
non-latent image portion (background) 5a, and corresponding to the
line of halftone dots in the non-latent image portion (background)
5a.
[0081] Here, the pitch refers to an interval in a d direction
indicated in the drawings.
[0082] If the latent image pattern 5 and the visualization pattern
6 are overlapped, as illustrated in FIG. 2(c), the non-latent image
portion (background) 5a and the hairlines 6a overlap to correspond
to each other. Meanwhile, the latent image portion 5b shifted from
the non-latent image portion (background) 5a and the hairlines 6a
by the pitch of 1/2 is visualized.
[0083] In FIG. 3, FIG. 3(a) is an enlarged schematic diagram
illustrating halftone dots forming an image in the latent image
pattern 5, viewed from the top, FIG. 3(b) is an enlarged schematic
diagram illustrating hairlines forming the visualization pattern 6,
viewed from the top, and FIG. 3(c) is a schematic enlarged diagram
illustrating a state in which the latent image pattern 5 and the
visualization pattern 6 are overlapped.
[0084] The latent image pattern 5 illustrated in FIG. 3(a) is the
same as the pattern illustrated in FIG. 2(a). In addition, the
visualization pattern 6 illustrated in FIG. 3(b) is the same as the
pattern illustrated in FIG. 2(b).
[0085] If the latent image pattern 5 and the visualization pattern
6 are overlapped so that the latent image portion 5b and the
hairlines 6a overlap to correspond to each other, as illustrated in
FIG. 3(c), the non-latent image portion (background) 5a and the
hairlines 6a are alternately located with being shifted by the
pitch of 1/2 to become like a background, and a blank portion of
the latent image portion 5b that is shifted by the pitch of 1/2 is
visualized to have the same shape as the latent image portion 5b to
become visible.
[0086] The display print region 7 indicates display content such as
product information, and a multi-colored picture can be formed over
the entire region. In the latent image sheet 2 and the
visualization sheet 3, the display contents in the display print
region 7 may be equivalent, or may be different. When these are
printed, an anchor coat for making the adhesiveness of ink better
may be interposed between an ink layer of an image and the surface
of the base material 11.
[0087] In addition, the latent image pattern 5 can also be formed
on the surface of the rear surface laminate 3.
[0088] Furthermore, the latent image portion 5b may be formed into
an image having any shape such as a character, a picture, a symbol,
and a pattern.
[0089] As the laminates 2, 3, and 4, laminates used for a normal
soft packaging bag can be used. As the base material 11, paper, a
metal foil, a synthetic resin film, or the like that is formed by
one layer or a plurality of layers is used. As an example, a
synthetic resin film, paper, metal foil, and the like such as
low-density polyethylene resin (LDPE), high-density polyethylene
resin (HDPE), linear low-density polyethylene resin (LLDPE),
polypropylene resin (PP), polyolefin series resin such as
polyolefin series elastomer, polyester series resin such as
polyethylene terephthalate resin (PET), polybutylene terephthalate
resin (PBT), and polyethylene naphthalate resin (PEN), cellulosic
resin such as cellophane and cellulose triacetate (TAC),
polymethylmethacrylate (PMMA) resin, ethylene vinyl acetate series
copolymer resin (EVA), ionomer resin, polybutene series resin,
polyacrylonitrile series resin, polyamide series resin, polystyrene
series resin (PS), polyvinyl chloride series resin (PVC),
polyvinylidene chloride series resin (PVDC), polycarbonate resin
(PC), fluorine series resin, and urethane series resin that can be
used as a transparent sheet 11a is used alone, or in
combination.
[0090] In addition, as described above, it is preferable that
either one of the laminates 2 and 3 be a transparent sheet.
[0091] As the sealant layer 12, polyolefin series resin is
generally used, and specifically, ethylene series resin such as
low-density polyethylene resin, medium-density polyethylene resin,
linear low-density polyethylene resin, ethylene-vinyl acetate
copolymer, and ethylene-.alpha.-olefin copolymer, or polypropylene
series resin such as homopolypropylene resin, propylene-ethylene
random copolymer, propylene-ethylene block copolymer, and
propylene-.alpha.-olefin copolymer is used. In addition, a
multilayered film obtained by combining these resins may be used in
some cases.
[0092] As a specific configuration example of the laminates 2, 3,
and 4, a film having a configuration including PET/print
layer/adhesive layer/stretched polyamide resin film (hereinafter,
abbreviated as "ONY")/adhesive layer/LLDPE, ONY/adhesive
layer/LLDPE, ONY/adhesive layer/ONY/adhesive layer/LLDPE,
paper/LDPE/aluminum foil/LDPE, paper/LDPE, and the like can be
given as examples.
[0093] Because the packing container 1 of the present embodiment is
sealed so that the latent image pattern 5 and the visualization
pattern 6 can be overlapped corresponding to each other, only by
pressing the latent image sheet 2 and the visualization sheet 3,
which are the front and the rear surfaces of the packing container
1, against each other, and bringing the inner surfaces of the
latent image sheet 2 and the visualization sheet 3 into contact
with each other, the latent image pattern 5 and the visualization
pattern 6 can be overlapped, and the latent image portion 5b is
visualized, so that an image-forming member becomes visible. This
can prevent a third party from manufacturing, and prevent
forgery.
[0094] In the packing container 1 of the present embodiment, linear
halftone dots and hairlines are used as the latent image pattern 5
and the visualization pattern 6. Nevertheless, these need not be
straight lines as long as they are in a parallel state, and may be
formed into curved lines, circular shapes, circles, and the
like.
[0095] In the packing container 1 of the present embodiment, the
latent image pattern 5 and the visualization pattern 6 can be
formed by printing print ink on the sheets 2 and 3. At least either
one of the latent image pattern and the visualization pattern may
be formed by a light reflection film provided along a fine
irregularity surface having a light diffraction function. Light is
reflected and diffracted by the light reflection film, and
furthermore, the reflected and diffracted light has a rainbow
design that varies in color depending on an angle at which the
light is viewed. Thus, the light reflection film has an esthetic
appeal and superior decorativeness. In addition, because copying
and imitating are extremely difficult, the light reflection film is
further superior in forgery prevention. Such a light reflection
film can be formed by causing a sheet coated with thermoplastic
resin to continuously travel between a roll around which a matrix
having an irregularity pattern forming a diffractive grating having
a light diffraction function or a hologram is wound, and a roll
forming a pair with the roll, and to pass therethrough to be
pressed, and by transferring the irregularity pattern.
[0096] In the packing container 1 of the present embodiment, the
latent image pattern 5 and the visualization pattern 6 serving as
an authentication set are formed on the main body front surface
laminate 2 and the main body rear surface laminate 3. Nevertheless,
as illustrated in FIG. 4, as a packing container 1A, in addition to
the authentication set, an additional authentication set can be
arranged at a bottom portion side position of the packing container
1, that is, an authentication set can be formed on the main body
front surface laminate 2 and the bottom tape 4, or on the main body
rear surface laminate 3 and the bottom tape 4.
[0097] In this case, the content is moved to an upper portion in a
standing (standing position) state of the packing container 1A, and
the bottom tape 4 and the lower end of the sheet 2, or the bottom
tape 4 and the lower end of the sheet 3 are sandwiched and pressed,
whereby a latent image can be visualized and made visible in a
region provided with the additional authentication set. In this
example, in a state in which a latent image does not become visible
in a display state of the packing container 1A serving as a
product, true-false determination or the like can be performed as
necessary using the additional authentication set.
Second Embodiment
[0098] The second embodiment of a packing container according to
the present invention will be described below based on the
drawings.
[0099] FIG. 5 is a front view illustrating a packing container in
the present embodiment.
[0100] In the present embodiment, a difference from the
above-described first embodiment lies in an outline shape of the
container and a bottom portion shape, and corresponding components
other than these are assigned the same signs and the description
thereof will be omitted.
[0101] A packing container 1B in the present embodiment is not
provided with the laminate 4 serving as a bottom portion, and only
the sheets 2 and 3 serving as the front and rear surfaces of the
pouch container are sealed.
[0102] As illustrated in FIG. 5, in the packing container 1B, the
latent image pattern 5 and the visualization pattern 6 serving as
an authentication set that makes a latent image visible, by being
combined are formed on the sheets 2 and 3 serving as the front and
the rear surfaces of the pouch. The seal portions 22 and 23 are
formed on the two sheets 2 and 3. After that, a process is sent to
a process of supplying content.
[0103] In the packing container 1B, content to be stored inside is
not limited to liquid, and furthermore, the content need not to be
transparent. Nevertheless, in this case, only the latent image
pattern region 5 of the latent image sheet 2 can be made
transparent.
[0104] In addition, in the packing container 1B, the content is
supplied with such an allowance for causing the latent image
pattern 5 of the latent image sheet 2 and the visualization pattern
6 of the visualization sheet 3 to overlap. Specifically, as
illustrated in FIG. 5, in a standing (standing position) state of a
content-supplying process, content assumed to be liquid and solid
is supplied into the packing container 1B to about a height
indicated by a sign W. A filling indication line W can be formed by
being printed simultaneously with any of the latent image pattern
5, the visualization pattern 6, and the display print region 7.
[0105] After the content is supplied, an upper end portion is
sealed, and the packing container 1B is completed as a shipped
product.
[0106] Also in the packing container 1B of the present embodiment,
a functional effect similar to that in the first embodiment can be

[0107] The third embodiment of a packing container according to the
present invention will be described below based on the
drawings.
[0108] FIG. 6 is a front view illustrating a packing container in
the present embodiment.
[0109] In the present embodiment, a difference from the
above-described first and second embodiments lies in an outline
shape of the container and a side portion shape, and corresponding
components other than these are assigned the same signs and the
description thereof will be omitted.
[0110] A packing container 1C in the present embodiment is a pouch
container provided with laminates 2A and 3A for a gusset that serve
as side portions. In the standing (standing position) state, the
two sheets 2A and 3A are sandwiched between the sheets 2 and 3
serving as the front and the rear surfaces of the pouch, and
sealed.
[0111] As illustrated in FIG. 6, in the packing container 1C, the
latent image pattern 5 and the visualization pattern 6 serving as
an authentication set that makes a latent image visible, by being
combined are formed on the sheets 2 and 3 serving as the front and
the rear surfaces of the pouch. The latent image pattern 5, the
visualization pattern 6, and the display print region 7 are printed
on these two sheets 2 and 3, and the seal portions 22 and 23 are
formed in a state in which the sheets 2A and 3A are sandwiched.
After that, a process is sent to a process of supplying
content.
[0112] As illustrated in FIG. 6, in the packing container 1C,
content to be stored inside may be solid. In this case, the solid
content can be stored in a state of being located on the bottom
side of the filling indication line W (so as not to exceed the
filling indication line W).
[0113] After the content is supplied, an upper end portion is
sealed, and the packing container 1C is completed as a shipped
product.
[0114] Also in the packing container 1C of the present embodiment,
a functional effect similar to that in the above-described
embodiments can be provided.
Fourth Embodiment
[0115] The fourth embodiment of a packing container according to
the present invention will be described below based on the
drawings.
[0116] FIG. 7 is a front view illustrating a packing container in
the present embodiment.
[0117] In the present embodiment, a difference from any of the
above-described first to third embodiments lies in the shape of the
container and a sheet state, and corresponding components other
than these are assigned the same signs and the description thereof
will be omitted.
[0118] In a packing container 1D in the present embodiment, both of
the sheets 2 and 3 are transparent plastic plates having elasticity
and rigidity, an electronic component or the like is stored in a
sandwiched state in the vicinity of the center of the two sheets 2
and 3, and the surrounding thereof is sealed.
[0119] As illustrated in FIG. 7, in the packing container 1D, the
latent image pattern 5 and the visualization pattern 6 serving as
an authentication set that makes a latent image visible, by being
combined are formed on the sheets 2 and 3 serving as the front and
the rear surfaces of the packing container 1D. In addition, In FIG.
7, SDHC (trademark) and a logo are trademarks of SD-3C, LLC.
[0120] Also in the packing container 1D of the present embodiment,
a functional effect similar to that in the above-described
embodiments can be provided. Furthermore, because the sheets have
rigidity, the latent image pattern 5 and the visualization pattern
6 are not shifted. In addition, it can become easily visible that
an electronic component or the like is a genuine product.
Fifth Embodiment
[0121] The fifth embodiment of a packing container according to the
present invention will be described below based on the
drawings.
[0122] FIG. 8A is a front view illustrating a packing container in
the present embodiment, and FIG. 8B is a cross-sectional view in
FIG. 8A.
[0123] In the present embodiment, a difference from any of the
above-described first to fourth embodiments lies in the shape of
the container and a sheet state, and corresponding components other
than these are assigned the same signs and the description thereof
will be omitted.
[0124] A packing container 1E in the present embodiment is a Press
Through Package (PTP) individually storing contents WE being
medicine such as tablets. The sheet 2 is a transparent plastic
plate having elasticity and the sheet 3 is a film thinner than the
sheet 2, a tablet or the like is stored in a sandwiched state in
the vicinity of a center 1Ea of these sheets 2 and 3, and the
surrounding thereof is sealed.
[0125] In the packing container 1E, as illustrated in FIGS. 8A and
8B, the latent image pattern 5 of the authentication set is formed
on the sheet 2 serving as the front surface of the packing
container 1E, and the visualization pattern 6 is formed on the film
3 being the rear surface. The vicinity of the authentication set
need not be sealed.
[0126] Also in the packing container 1E of the present embodiment,
a functional effect similar to that in the above-described
embodiments can be provided. Furthermore, because the sheets have
rigidity, the latent image pattern 5 and the visualization pattern
6 are not shifted.
Sixth Embodiment
[0127] The sixth embodiment of a packing container according to the
present embodiment will be described below based on the
drawings.
[0128] FIG. 9 is a front developed view illustrating a state of a
packing container in a manufacturing process of the packing
container in the present embodiment, and FIG. 10 is a front view
illustrating a state of the packing container in the manufacturing
process of the packing container in the present embodiment.
[0129] The packing container 1 according to the present embodiment
differs from the first embodiment illustrated in FIGS. 1A and 1B in
the arrangement of the latent image pattern 5 and the visualization
pattern 6, and corresponding components are assigned the same signs
and the description thereof will be omitted.
[0130] In the manufacturing process of the packing container 1
according to the present embodiment, as illustrated in FIG. 9, a
sheet 1a having the laminates 2 and 3 formed so as to be coupled at
one end of an upper portion in the standing (standing position)
state is used.
[0131] As illustrated in FIG. 9, the packing container 1 according
to the present embodiment is manufactured using the sheet 1a in
which the laminates 2 and 3 are coupled. A coupled long film has
the laminates 2 and 3 to be cut down to form 2 packing containers.
Each of them is cut down along an outline so as to form the filling
opening portion 41, the discharge nozzle seal portion 24, the
discharge nozzle 32, the opening notch 35, the side seal portion
(seal portion) 22, and the bottom seal portion (seal portion) 23
that are illustrated in FIG. 1A and the like.
[0132] In addition, in the sheet 1a, as illustrated in FIG. 9, the
laminates 2 and 3 are formed so as to be coupled in the upper and
lower directions in the standing position state when the packing
container 1 is manufactured. In addition, a description will be
given using the laminate 2 as an example. As illustrated in FIG.
10, the laminate 2 is formed to be coupled at the upper portion in
the standing position state when the packing container 1 is
manufactured.
[0133] In the manufacturing method of the packing container 1
according to the present embodiment, after the latent image pattern
region (latent image pattern) 5, the visualization pattern region
(visualization pattern) 6, and the display print region 7 are
printed on the sheet 1a illustrated in FIG. 9, using ink, the sheet
1a is folded back at a scored line 8, and the laminate 4 serving as
the bottom tape 4 is tucked in, and the discharge nozzle seal
portion 24, the side seal portion (seal portion) 22, the bottom
seal portion (seal portion) 23 are sealed. The scored line 8 is set
at a position in the vicinity of the center of the sheet 1a that is
in the vicinity of the filling opening portion 41 in each of the
packing containers 1, so as to be substantially parallel to the
filling opening portion 41.
[0134] After the sheet 1a is folded back by doubling up at the
scored line 8, and the above-described sealing is applied, or
simultaneously with the sealing, the sheet 1a is cut down so as to
have a predetermined outline, and the packing containers 1 coupled
at the upper portion in the standing (standing position) state are
formed. After that, in the filling opening portion 41, the two
packing containers 1 are cut off.
[0135] In the present embodiment, the visualization pattern region
(visualization pattern) 6 and the display print region 7 are
provided at positions extremely close to the filling opening
portion 41. With this configuration, in the packing container 1,
content supplied in the standing (standing position) state of the
content-supplying process can avoid disturbing the adhesion of the
latent image pattern 5 and the visualization pattern 6. Thus, only
by bringing the inner surfaces of the latent image sheet 2 and the
visualization sheet 3 into contact with each other, the latent
image pattern 5 and the visualization pattern 6 can be overlapped,
and the latent image portion 5b can be easily visualized, so that
an image-forming member can be made visually recognizable.
[0136] At the same time, in the position adjustment in the bag
manufacturing preparation, diagrams and images such as characters
and images in the latent image portion 5b can be visualized, and it
can be visually checked easily that the front and the rear of the
pouch are matched (that no position shift occurs between the latent
image sheet 2 and the visualization sheet 3). This can enhance
yield by shortening work time and reducing work errors.
Furthermore, even when it is checked during the bag manufacturing
whether pasting positions (sealing positions) of the latent image
sheet 2 and the visualization sheet 3 are shifted, the presence or
absence of a shift can be easily checked only by visually
recognizing whether characters and images and the like are
visualized in the latent image portion 5b.
Seventh Embodiment
[0137] The seventh embodiment of a packing container according to
the present embodiment will be described below based on the
drawings.
[0138] FIG. 11 is a front developed view illustrating a state of a
packing container in a manufacturing process of the packing
container in the present embodiment. FIG. 12 is a front view
illustrating a state of the packing container in the manufacturing
process of the packing container in the present embodiment. FIG. 13
is a front developed view illustrating a state of the packing
container in the manufacturing process of the packing container in
the present embodiment. FIG. 14 is a front developed view
illustrating a state of the packing container in the manufacturing
process of the packing container in the present embodiment.
[0139] The packing container 1 according to the present embodiment
differs from the sixth embodiment illustrated in FIGS. 9 and 10 in
the arrangement of a scored line, and corresponding components are
assigned the same signs and the description thereof will be
omitted.
[0140] In the manufacturing process of the packing container 1
according to the present embodiment, as illustrated in FIG. 11, a
sheet 1b having the laminates 2 and 3 formed so as to be coupled at
one end of an upper portion in the standing (standing position)
state is used.
[0141] Similarly to the sixth embodiment, as illustrated in FIG.
11, the packing container 1 according to the present embodiment is
manufactured using the sheet 1b in which the laminates 2 and 3 are
coupled. A coupled long film has the laminates 2 and 3 to be cut
down to form 2 packing containers. Each of them is cut down along
an outline so as to form the filling opening portion 41, the
discharge nozzle seal portion 24, the discharge nozzle 32, the
opening notch 35, the side seal portion (seal portion) 22, and the
bottom seal portion (seal portion) 23.
[0142] In addition, in the sheet 1a, as illustrated in FIG. 11, the
laminates 2 and 3 are formed so as to be coupled in the upper and
lower directions in the standing position state when the packing
container 1 is manufactured. In addition, a description will be
given using the laminate 3 as an example. As illustrated in FIG.
12, the laminate 3 is formed to be coupled at the bottom portion
(bottom side) in the standing position state when the packing
container 1 is manufactured.
[0143] In a manufacturing method of the packing container 1
according to the present embodiment, after the latent image pattern
region (latent image pattern) 5, the visualization pattern region
(visualization pattern) 6, and the display print region 7 are
printed on the sheet 1a illustrated in FIG. 11, using ink, the
sheet 1a is folded back at scored lines 8a and 8b, and the laminate
4 serving as the bottom tape 4 is tucked in, and the discharge
nozzle seal portion 24, the side seal portion (seal portion) 22,
the bottom seal portion (seal portion) 23 are sealed. The two
scored lines 8a and 8b are set in the vicinity of left and right
quarter positions in the width direction of the sheet 1a that are
in the vicinity of the filling opening portions 41 of the
respective packing containers 1, and are set so as to be
substantially parallel to the filling opening portions 41.
[0144] After the left and right ends of the sheet 1a are folded
back at the scored lines 8a and 8b toward a center line 9, and the
above-described sealing is applied, or simultaneously with the
sealing, the sheet 1a is cut down so as to have a predetermined
outline, and the packing containers 1 coupled at the upper portion
in the standing (standing position) state are formed. After that,
in the bottom portion 4 in the vicinity of the center line 9, the
two packing containers 1 are cut off.
[0145] In the present embodiment, the visualization pattern region
(visualization pattern) 6 and the display print region 7 are
provided at positions extremely close to the scored lines 8a and
8b. In this manner, because distances from the scored lines 8a and
8b to the visualization pattern region (visualization pattern) 6
and the display print region 7 are close, when the left and right
ends of the sheet 1a are folded back at the scored lines 8a and 8b
toward the center line 9, the position adjustment of the
visualization pattern region (visualization pattern) 6 and the
display print region 7 becomes easy, the occurrence of a shift can
be prevented, and accurate visualization can be performed in the
bag manufacturing. Yields in the bag manufacturing can be thereby
enhanced.
[0146] Furthermore, in a printing process, a bag-manufacturing
process, and the like, as indicated by arrows in FIG. 13, when the
sheet 1a is pulled by the tension (tensile force) of a
manufacturing device, or heating processing in the printing
process, a sealing process, or the like is performed, or if heat is
applied during the manufacturing, the contraction and the extension
of the sheet 1a occur non-uniformly, and twist is generated in some
cases. Because distances from the scored lines 8a and 8b to the
visualization pattern region (visualization pattern) 6 and the
display print region 7 are close, and distances between the
visualization pattern region (visualization pattern) 6 and the
display print region 7 across the scored lines 8a and 8b are close,
the influence of twist can be reduced, and the occurrence of a
shift in the position adjustment of the visualization pattern
region (visualization pattern) 6 and the display print region 7 can
be prevented.
[0147] In addition, as indicated by broken lines in FIG. 14, the
term twist means a shift Z generated in a crosswise direction in
the standing (standing position) state of the manufactured packing
container 1, in a width direction (the left and right direction
indicated in the drawing) in the long sheet 1a.
[0148] In the packing container 1 of the present embodiment, the
latent image pattern 5 and the visualization pattern 6 are arranged
in the vicinity of the scored lines 8a and 8b set in the vicinity
of the filling opening portions 41 in the upper portions in the
standing (standing position) state. Thus, content supplied in the
standing (standing position) state during the content-supplying
process can avoid disturbing the adhesion of the latent image
pattern 5 and the visualization pattern 6. Thus, only by bringing
the inner surfaces of the latent image sheet 2 and the
visualization sheet 3 into contact with each other, the latent
image pattern 5 and the visualization pattern 6 can be overlapped,
and the latent image portion 5b can be easily visualized, so that
an image-forming member can be made visually recognizable.
[0149] At the same time, in the position adjustment in the bag
manufacturing preparation, diagrams and images such as characters
and images in the latent image portion 5b can be visualized, and it
can be visually checked easily that the front and the rear of the
pouch are matched (that no position shift occurs between the latent
image sheet 2 and the visualization sheet 3). This can enhance
yield by shortening work time and reducing work errors.
Furthermore, even when it is checked during the bag manufacturing
whether pasting positions (sealing positions) of the latent image
sheet 2 and the visualization sheet 3 are shifted, the presence or
absence of a shift can be easily checked only by visually
recognizing whether characters and images and the like are
visualized in the latent image portion 5b.
Eighth Embodiment
[0150] The eighth embodiment of a packing container according to
the present embodiment will be described below based on the
drawings.
[0151] FIGS. 15 and 16 are explanatory diagrams illustrating a
latent image pattern and a visualization pattern in the present
embodiment.
[0152] The packing container 1 according to the present embodiment
differs from each of the above-described embodiments in a latent
image pattern and a visualization pattern, and a manufacturing
method thereof, and corresponding components are assigned the same
signs and the description thereof will be omitted.
[0153] In FIG. 15, FIG. 15(a) is an enlarged schematic diagram
illustrating halftone dots forming an image in the latent image
pattern 5, viewed from the top, and FIG. 15(b) is an enlarged
schematic diagram illustrating hairlines forming the visualization
pattern 6, viewed from the top.
[0154] As illustrated in FIG. 15(b), the latent image pattern 5 is
formed by a non-latent image portion (background) 5a formed by
halftone dots having a uniform pitch, and a latent image portion 5b
formed by halftone dots having a shifted pitch with respect to the
non-latent image portion 5a. A line width M1 of each of the
halftone dots, and an interval M2 of the line of the halftone dots
are set in the following manner.
[0155] As illustrated in FIG. 15(a), the visualization pattern 6 is
formed by hairlines 6a having a pitch equal to a pitch in the
non-latent image portion (background) 5a, and corresponding to the
lines of halftone dots in the non-latent image portion (background)
5a. In addition, a line width M1 of each of the hairlines, and an
interval M2 of the hairlines are set in the following manner.
[0156] Here, the pitch refers to an interval in a d direction
indicated in the drawings.
0.01 mm.ltoreq.M1.ltoreq.0.15 mm
0.01 mm.ltoreq.M2.ltoreq.0.15 mm <Condition 1>
[0157] By using a range of the above-described line width M1, the
possibility of the occurrence of a printing failure caused when a
line width is too thin and ink cannot be applied on a plate can be
reduced. In addition, by setting the interval M2 to fall within the
above-described range, a situation in which an interval is too
narrow and ink is blurred, and visualization cannot be performed
can be prevented.
[0158] Furthermore, by setting the line width M1 and the interval
M2 to fall into the above-described ranges, a replica can be
prevented from being easily manufactured by scanning the latent
image pattern 5 and the visualization pattern 6. If the line width
M1 and the interval M2 are made larger, scanning becomes easy in
some cases, which is not preferable.
0.03 mm.ltoreq.M1.ltoreq.0.45 mm
0.03 mm.ltoreq.M2.ltoreq.0.45 mm
0.2.ltoreq.(M2/M1).ltoreq.10 <Condition 2>
[0159] By using a range of the above-described line width M1, the
possibility of the occurrence of a printing failure caused when a
line width is too thin and ink cannot be applied on a plate can be
reduced. In addition, by setting the interval M2 to fall within the
above-described range, a situation in which an interval is too
narrow and ink is blurred, and visualization cannot be performed
can be prevented.
[0160] Furthermore, by setting the line width M1 and the interval
M2 to fall into the above-described ranges, a replica can be
prevented from being easily manufactured by scanning the latent
image pattern 5 and the visualization pattern 6.
[0161] Furthermore, by setting the line width M1 and the interval
M2, and the ratio thereof to fall into the above-described ranges,
a replica can be prevented from being easily manufactured by
scanning the latent image pattern 5 and the visualization pattern
6. If the line width M1 and the interval M2, and a ratio M2/M1 are
made larger, scanning becomes easy in some cases, which is not
preferable.
[0162] These data are described in Table 1.
[0163] In addition, conditions are similar to examples described
later.
TABLE-US-00001 TABLE 1 CELL PLATE Line width (mm) Interval (mm)
Ratio Determination 0.009 -- -- C: Unprintable 0.16 0.5 1:3.1 C:

0.15 0.03 1:0.2 A 0.1 0.1 1:1 A 0.15 0.02 1:0.13 C: Without
reproducibility
[0164] In addition, in Table 1, A: with reproducibility and
security, C: without security, unprintable, or without
reproducibility are indicated.
[0165] In the present embodiment, because parameters are set as
described above, forgery performed by the others can be prevented,
and a vivid latent image can be manufactured to be visible.
[0166] Here, in the printing process of the latent image pattern 5
and the visualization pattern 6, as illustrated in FIG. 16(a), when
a screenless plate P1 in which an embankment crossing over in the
width direction in a thin line is not formed is used, when the line
width M1 is too thin, ink may spill over and the line width M1 may
fail to be correctly set. It is therefore preferable to set within
the range of the above-described line width M1.
[0167] In addition, in the printing process of the latent image
pattern 5 and the visualization pattern 6, as illustrated in FIG.
16(b), when a cell plate P2 having a cylinder cell holding ink is
used, when the line width M1 is too thin, ink may fail to be
applied onto the plate, and a predetermined line width M1 may fail
to be correctly set. It is therefore preferable to set within the
range of the above-described line width M1. At the same time, if
the width of the interval M2 is narrow, ink is blurred, and
visualization cannot be performed. It is therefore preferable to
set within the range of the above-described line width M2.
[0168] In each of the above-described embodiments, by making a
difference in size between the latent image pattern 5 and the
visualization pattern 6 larger, that is, by forming the latent
image pattern 5 to be larger than the visualization pattern 6, or
by forming the visualization pattern 6 to be larger than the latent
image pattern 5, even when a position shift between the latent
image sheet 2 and the visualization sheet 3 occurs and a pitch
shift accordingly occurs, the latent image pattern 5 and the
visualization pattern 6 can be overlapped and a latent image can be
visualized.
[0169] With this configuration, not only when the latent image
pattern 5 and the visualization pattern 6 are separated from the
seal portions 22, 23, and 24, by making either of the latent image
pattern 5 and the visualization pattern 6 larger, even if the
positions of the latent image sheet 2 and the visualization sheet 3
shift to some extent, an image can be formed.
Examples
[0170] Next, examples in the present embodiment will be
described.
[0171] Using a gravure printer, low-density polyethylene resin was
prepared as the sheet 1a, printing conditions were set in the
following manner, the latent image pattern 5 and the visualization
pattern 6 were printed, and a reproducibility check of
visualization was performed.
<Printing Conditions>
[0172] Gravure printing type (screenless plate, cell plate) [0173]
Printing speed (running speed of the sheet 1a; m/min) [0174] Ink
viscosity (CPS: centipoise=mPas) [0175] Line width M1 (mm) [0176]
Interval M2 (mm) [0177] M2/M1 (ratio)
[0178] These conditions are indicated in Table 2, and the results
thereof are indicated in Table 3.
[0179] In addition, in the reproducibility check of visualization,
when visualized characters and symbols cannot be visually
determined, the reproducibility was determined as "without
reproducibility", when scanning can be performed using a copying
machine or the like, the reproducibility was determined as "without
security", and when an abnormality in a pattern was visually found
before the visualization of a latent image, the reproducibility was
determined as "unprintable".
TABLE-US-00002 TABLE 2 Printing speed (m/min) Viscosity (CPS) 100
10~60 150 200 250 300
TABLE-US-00003 TABLE 3 Ratio Plate type Line width (mm) 1:0.4 1:0.5
1:1 1:2 1:3 Cell plate 0.08 C C B C C 0.01 C B A A C 0.05 C A A A B
0.1 B A A A A 0.15 B A A A A 0.2 C: Without security Screenless
plate 0.08-0.2 C: Visualization impossible
[0180] In addition, in Table 3, A: with reproducibility and
security, B: no problem in reproducibility (level inferior to A),
with security, C: without security, or visualization impossible are
indicated.
[0181] Thus, it can be seen that, when gravure printing is
performed, the line width M1 in the range in which the
reproducibility of visualization is provided, and the security can
be ensured is preferably in the range of 0.01
mm.ltoreq.M1.ltoreq.0.15 mm for both of the latent image pattern 5
and the visualization pattern 6, and the ratio of the line width M1
and the interval M2 is in the range of
0.5.ltoreq.(M2/M1).ltoreq.2.
[0182] In addition, in the screenless plate, ink spills over in all
the conditions, and the reproducibility was determined as
visualization impossible. Nevertheless, if ink and machine
conditions or the like are reviewed, and if printing can be
performed under the above-described conditions, printing can be
performed using the screenless plate.
[0183] From these results, by setting conditions such as the line
width M1, the interval M2, and the ratio into the above-described
range, a packing container can be provided that can ensure
reproducibility in the visualization of a latent image while
maintaining security.
Ninth Embodiment
[0184] The ninth embodiment of a packing container according to the
present embodiment will be described below based on the
drawings.
[0185] The usage of the above-described visualization pattern and
the latent image pattern is not limited to the packing container
having the configuration described in each of the embodiments, and
they can be used in other packing containers having various
configurations, and the formation location of each pattern is not
limited to that in each of the above-described embodiments.
[0186] For example, in each of the above-described embodiments, a
pair of the latent image pattern region 5 and the visualization
pattern region 6 are formed on the latent image sheet 2 and the
visualization sheet 3, respectively. Nevertheless, if these
patterns can be overlapped, they need not be formed on separated
sheets. For example, a configuration in which these patterns are
formed on the same sheet to form an authentication set, and the
latent image pattern region 5 and the visualization pattern region
6 are overlapped by folding the sheet, and a latent image is
visualized may be used. Such an example will be described
below.
[0187] FIG. 17A is a front view illustrating a packing container 51
in the present embodiment, and FIG. 17B is a front view
illustrating a state in which the upper portion of the packing
container 51 in FIG. 17A is folded.
[0188] In the drawings, the packing container 51 is a container
having a configuration in which a main body front surface laminate
52 and a main body rear surface laminate 53 are opposed, and a
storage unit 54 is provided therebetween, and a container upper
portion 55, a container bottom portion 56, and left and right
container side portions 57 and 58 are each provided with a seal
portion 59 so as to surround the storage unit 54 to seal the four
sides.
[0189] Specifically, two sheets of the main body front surface
laminate 52 and the main body rear surface laminate 53 are
overlapped, and the seal portions 59 on the four sides are formed
by heat-sealing the container upper portion, the container bottom
portion, and both container side portions, and the shape in front
view when the main body front surface laminate 52 facing front is
viewed is rectangle. When the packing container 51 is manufactured,
for example, two belt-like sheets (a belt-like sheet for the main
body front surface laminate, and a belt-like sheet for the main
body rear surface laminate) pulled out from separate roll members
or the like are overlapped, and for one container of the packing
container on the belt-like sheet, portions corresponding to three
sides of one container are heat-sealed in a state in which a
portion corresponding to a filling port is left. For making
suitable for heat-sealing, the main body front surface laminate 52
and the main body rear surface laminate 53 are formed of films of
laminates having at least a base material and a sealant layer, and
heat-sealing is performed by overlapping the sealant layers in an
opposed state.
[0190] A nozzle is inserted into a filling port of one container in
a continuous body of the packing containers, and liquid, powder,
and the like are supplied into the storage unit. If the supplying
ends, the portion of the filling port is heat-sealed and the
storage unit is closed, and the continuous containers are cut off
therebetween. A packing container having a storage unit filled with
a certain amount of content is thereby obtained for one container.
A storage unit including a discharge path for discharging content
is formed by heat-sealing as described later. In addition, by
cutting in or cutting down a heat-sealed portion of the storage
container, a portion for enabling the below-described engagement is
formed.
[0191] The packing container 51 includes a content discharge path
60. The content discharge path 60 is coupled to the storage unit
54, and extends over from the storage unit 54 to the container
upper portion 55. As illustrated in the drawing, the content
discharge path 60 tapers off to a point in a substantially cuspidal
shape protruding upward while the upper portion of the storage unit
54 extends upward, and is biased toward the above-described other
container side portion 58 side, and is formed in a substantially
triangular shape in a front view state. Furthermore, an upper end
portion of the content discharge path 60 is a discharge port
expected formation portion 61. In this manner, the discharge port
expected formation portion 61 is provided only on a container upper
corner portion side being the other container side portion 58
side.
[0192] The discharge port expected formation portion 61 is a
portion for obtaining a discharge port by removing a leading end
portion of the content discharge path 60 together with the seal
portion 59 approaching the leading end portion. In addition, for a
user opening the packing container so as to easily check a cutting
position visually, the discharge port expected formation portion 61
is indicated as a printing instruction line crossing over the
leading end portion of the content discharge path 60 in the
container width direction. In addition, for facilitating manual
cutting, in the discharge port expected formation portion 61, half
cut can be applied by laser emission to the front surface sides of
the main body front surface laminate 52 and the main body rear
surface laminate 53, or the front surface side of one sheet.
[0193] In the present embodiment, a seal boundary portion 62 on one
container side portion 57 of the above-described content discharge
path 60 has a slanted straight line shape. In this manner, the
content discharge path 60 in the present embodiment is formed as a
pathway having as both sides, a slanted seal boundary portion on
one container side portion 57 side, and a seal portion on the other
container side portion 58 side. On the side being one container
side portion 57 side of the content discharge path 60 across the
linear seal boundary portion 62, there are seal portions 59 on the
left and right sides of the storage unit 54, and a seal portion 59
having a width wider than the seal portion 59 of the container
bottom portion 56.
[0194] The wider width and wider area seal portion 59 is a
heat-sealed portion of the main body front surface laminate 52 and
the main body rear surface laminate 53, and a plate-like seal thin
plate 63 spreading as a plane is formed. As illustrated in the
drawing, the content discharge path 60 and the seal thin plate 63
having a wide width and a wide area plate-like shape are provided
side by side in the container width direction, and in front view,
the seal thin plate 63 has a triangular shape oriented in an
opposite direction to the content discharge path 60. By providing
the portion of the content discharge path 60 having a triangular
shape and a substantially cuspidal shape protruding upward, and the
portion of the seal thin plate 63, side by side in the container
width direction, the entire packing container 51 fits into the
rectangle.
[0195] As described above, in the container upper portion 55, the
content discharge path 60 and the seal thin plate 63 of the seal
portion 59 having a positional relationship of being arranged side
by side in the container width direction are provided with an
expected bent portion 64 extending in the container width
direction. The expected bent portion 64 is a portion at which the
container upper portion 55 is to be bent downward. In the present
embodiment, the expected bent portion 64 is set at a height
position passing through a substantially center portion in a
container height direction of the content discharge path 60 so that
a portion crossing over the range of the content discharge path 60
and a portion crossing over the range of the seal thin plate 63 of
the seal portion 59 have a substantially equal length.
[0196] The above-described expected bent portion 64 is formed in a
straight-line shape, and is provided so that, by bending the
container upper portion 55 at the position of the expected bent
portion 64, the inner surfaces of the main body front surface
laminate 52 and the main body rear surface laminate 53 in the
content discharge path 60 contact at the bent portion of the
container, to block the content discharge path 60 at the bent
portion of the container. A printing instruction line can be
provided at the position of the expected bent portion 64. This
facilitates the checking of the position at which the container is
to be bent, which is preferable.
[0197] In addition, the expected bent portion 64 in the present
embodiment is indicated as a dashed-dotted straight line in the
drawing. Nevertheless, it is only required that the content
discharge path 60 be blocked by the bending of the container, and
the shape is not limited to the shape in which an expected bent
portion itself has a straight-line shape, and a cross section of a
bent portion of a container becomes a corner-shape. In the present
embodiment, by bending the container, the cross section of the bent
portion of the container forms a small arc shape, and the content
discharge path 60 is blocked in this state.
[0198] The seal thin plate 63 is provided with a bent
state-maintaining means 66 for maintaining a bent state of the
container at an expected bent portion 65. The bent
state-maintaining means 66 in the present embodiment has a pair of
engagement portions 66a and 66b (first engagement portion and
second engagement portion) provided at opposite positions when the
container is bent in such a manner that the seal thin plate 63 is
bent at the expected bent portion 64 on the one container side
portion 57 on the seal thin plate 63. The engagement portion 66a
and the engagement portion 66b are provided so as to be able to
engage with each other.
[0199] As illustrated in FIG. 17A, the engagement portion 66a in
the present embodiment is an engagement piece 67 cutting-formed by
a cut applied so as to reach the outer rim of the container upper
portion 55 (upper end rim of the container). In addition, as
illustrated in the drawing, the engagement portion 66a has a
positional relationship of being arranged so as to face and be
separated in the container width direction from the discharge port
expected formation portion 61. In addition, the other engagement
portion 66b is an engagement piece 68 cutting-formed by a cut
applied so as to reach the side end rim of the one container side
portion 57 being a bottom portion of the seal thin plate 63. By
causing the engagement portions 66a and 66b, that is, the
engagement piece 67 and the engagement piece 68 to engage with each
other by bending the container, the bent state of the container is
maintained, and the blocked state of the content discharge path 60
is thereby maintained. If the engagement relationship of the
engagement piece 67 and the engagement piece 68 is released, a
restoring force generated in the container bent portion of the main
body front surface laminate 52 and the main body rear surface
laminate 53 causes the container upper portion 55 to rise up, so
that the content discharge path 60 is unblocked.
[0200] The packing container 51 of the present embodiment is
devised for facilitating the formation of a discharge port for
discharging content from the content discharge path 60. In other
words, the packing container 51 is devised for facilitating manual
cut down along the position of the discharge port expected
formation portion 61 located at the leading end portion of the
content discharge path 60. First, at the center of the container
upper portion 55, there is a longitudinal scored line portion 69
formed by discontinuous slits extending downward from the upper end
rim of the container upper portion to reach the vicinity of the
above-described seal boundary portion 62. In addition, there is a
slanted cutoff portion 70 that is connected to the lower end of the
longitudinal scored line portion 69, and is formed by slits applied
so as to reach the end portion of the discharge port expected
formation portion 61 in parallel with the seal boundary portion
62.
[0201] By longitudinally cutting off at the longitudinal scored
line portion 69, and then, nipping and holding a tongue-shaped
portion formed between the position of the cut-off longitudinal
scored line portion 69 and the slanted cutoff portion 70, and
pulling the tongue-shaped portion in the container width direction
toward the other container side portion 58 side, the discharge port
expected formation portion 61 is torn down, so that a discharge
port 71 (FIG. 17B) is easily formed.
[0202] In the packing container 51 according to the present
embodiment, the main body front surface laminate 52 is provided
with a latent image pattern region (latent image pattern) 75 and a
visualization pattern region (visualization pattern) 76 as
illustrated in FIG. 17A. In the present embodiment, the latent
image pattern region 75 and the visualization pattern region 76 are
formed at symmetrical positions with respect to the expected bent
portion 64 so as not to overlap content, and form an authentication
set that makes a latent image visible by overlapping each other
when the container upper portion 55 is bent downward. These
patterns are each printed using ink. In addition, in the main body
front surface laminate 52 and the main body rear surface laminate
53, portions corresponding to the latent image pattern region 75
and the visualization pattern region 76 are transparent. As the
latent image pattern region 75 and the visualization pattern region
76, those described in each of the above-described embodiments can
be similarly used.
[0203] As illustrated in FIG. 17B, the content discharge path 60
opened in the above-described manner can be closed by bending the
container at the position of the expected bent portion 64, causing
the engagement piece 67 and the engagement piece 68 serving as the
bent state-maintaining means 66 to engage with each other. Thus,
the operation of blocking the content discharge path 60 can also be
easily performed. In addition, when the content discharge path 60
is closed, true-false determination or the like can be performed
together by using an additional authentication set.
[0204] The packing container of the present invention can be used
for food, nonfood, medical products, favorite items, and the
like.
