Resin containers such as pouches are used as refill containers or packaging containers such as simple containers.

In recent years, counterfeits such as pouches are on the market overseas. If this goes around in large quantities, it can be very damaging. For this reason, there is a need for means for preventing the manufacture of imitations at low cost and without labor. For example, it is conceivable to attach a seal such as a security mark separate from the container to the surface of the container. However, if the seal is replaced, it will not help prevent forgery.
Therefore, various methods such as prevention of forgery formed on the container itself have been proposed.

(First embodiment)
Hereinafter, 1st Embodiment of the packaging container which concerns on this invention is described based on drawing.
1A is a front view showing a packaging container in the present embodiment, and FIG. 1B is a cross-sectional view taken along the line bb ′ in FIG. 1A.

The packaging container 1 which concerns on this embodiment is a refill container which consists of a laminated body which has at least the base material 11 and the sealant layer 12, as shown to FIG. 1A and FIG. 1B. The refill container is formed by forming the main body surface laminated body 2 and the main body rear surface laminated body 3 with the sealant layer on the inner side, and folding another laminated body with the sealant layer on the outer side to form the bottom tape 4. And a standing pouch shape inserted between the main body front surface laminate 2 and the main body back surface laminate 3 and sealed at the periphery. The standing pouch-shaped container can easily be a large-capacity container because the bottom tape 4 spreads.

As the base material 11 of the laminates 2, 3, and 4, a vapor deposition layer is formed by vapor-depositing a metal such as aluminum and tin, a metal oxide such as silica and alumina on a transparent sheet. In addition, a metal foil film can be attached to the transparent sheet, and the laminates 2, 3, and 4 can include a printing layer, an adhesive layer, and the like.

As shown in FIG. 1B, side seal portions (seal portions) 22 are provided on both sides of the main body surface laminate 2 and the main body back surface laminate 3, and the main body surface laminate 2, the bottom tape 4, and the main body back surface. A bottom seal portion (seal portion) 23 is provided below the laminated body 3 and the bottom tape 4.

In the upper part of the front surface laminate 2 and the back surface laminate 3, a filling nozzle 41 and a pouring nozzle seal 32 for pouring the contents are formed together with the pouring nozzle seal portion 24. The tip of the dispensing nozzle 32 is sealed by the dispensing nozzle tip seal portion 24, and forms a spout by being cut off from the opening notch 35. In the vicinity of the dispensing nozzle 32 and the opening notch 35, a plurality of laser cut lines may be provided in parallel with the planned opening line.

In the packaging container 1 according to the present embodiment, the main body surface laminate 2 which is a latent image sheet is provided with a latent image pattern region (latent image pattern) 5 and a display print region 7 as shown in FIG. 1A. It has been. The latent image pattern area 5 and the display print area 7 are each printed using ink. As shown in FIG. 1A, a visualization pattern region (visualization pattern) 6 and a display print region 7 are provided on the main body back surface laminate 3 as a visualization sheet in the packaging container 1. The visualization pattern area 6 and the display print area 7 are printed using ink, respectively.

Further, in the latent image sheet 2 and the visualization sheet 3, at least one of the portions corresponding to the latent image pattern region 5 and the visualization pattern region 6 is transparent. The parts 22, 23, 24, etc. need not be transparent. If the latent image sheet 2 in a predetermined part of the latent image pattern area 5 is transparent, the visualization pattern area 6 in the corresponding visualization sheet 3 may be transparent, but may be opaque. Alternatively, if the visualization sheet 3 in a predetermined part of the visualization pattern area 6 is transparent, the latent image pattern area 5 in the corresponding latent image sheet 2 may be transparent or opaque.

The pair of latent image pattern area 5 and visualization pattern area 6 form an authentication set that allows the latent image to be visually recognized by being combined.

As shown in FIG. 1A, when the packaged container 1 is a liquid, the packaging container 1 simply overlaps the latent image pattern 5 of the latent image sheet 2 and the visualization pattern 6 of the visualization sheet 3. The contents will be filled with a margin. Specifically, as shown in FIG. 1A, the packaging container 1 is preferably filled with a liquid up to the height indicated by the filling line W in a standing (standing) state. Also, the latent image pattern 5 and the visualization pattern 6 are provided at the upper position.

In addition, the packaging container 1 such as a pouch has flexibility. Therefore, the filling rate of the contents is smaller than the above state, and there is room in the container, and the inner side surfaces of the latent image sheet 2 and the visualization sheet 3 can be brought into contact with or brought close to a state where the latent image is visible. For example, the arrangement of the latent image pattern 5 and the visualization pattern 6 is not limited to the upper side of the packaging container 1.

Further, there is no problem as long as the filling is transparent, but when the filling is made of an opaque liquid, powder, or small solid is used as the contents, the latent image pattern 5 and the visualization sheet 3 of the latent image sheet 2 are used. It is necessary to prevent the contents from being applied to the portion corresponding to the visualization pattern 6. In addition, if the latent image pattern of the latent image sheet and the visualization pattern of the visualization sheet are provided in the vicinity of the seal portion, the overlay position may be shifted and the latent image may not be visualized without being visualized. It is necessary to separate from the seal part by a distance (do not overlap with the seal part).

Further, as shown in FIG. 1A, the latent image pattern 5 and the visualization pattern 6 are provided at positions separated from any 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 are converted into the latent image due to deformation of the sheets 2 and 3 when the seal is formed. Is not preferable because it may be shifted from a position where it can be easily revealed, and a latent image may not be partially revealed.

The latent image pattern 5 and the visualization pattern 6 are paired with each other, and the specific visualization pattern 6 corresponds to the specific latent image pattern 5. By superimposing a visualization pattern 6 corresponding to a specific latent image pattern 5, the latent image can be visualized and recognized. On the other hand, even if the visualization patterns that do not correspond are overlapped, generally, the latent image cannot be visualized and cannot be recognized. Therefore, when the latent image sheet 2 and the visualization sheet 3 are configured as sheets forming the front and back of the packaging container 1, the bonding positions of the latent image sheet 2 and the visualization sheet 3 are made to correspond to each other. Can be sealed as an authentication set.

The latent image sheet 2 may be provided with a latent image pattern on the entire surface, or may be provided with a latent image pattern 5 in a partial area. Further, 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. Similarly, the visualization sheet 3 may be one in which the visualization pattern 6 is provided in a part of the region, and is divided into a plurality of regions, and the visualization pattern 6 is provided in each of the plurality of regions. May be.

The latent image pattern 5 is composed of a latent image and a background, and both the latent image and the background are composed of a periodic pattern. The visualization pattern 6 is also configured with a periodic pattern.

In the latent image pattern 5, as a periodic pattern constituting the latent image and the background, for example, a line composed of a plurality of parallel lines can be used, and a line between the plurality of parallel lines is a line. A shape margin is arranged. Desirably, the width of the parallel lines is equal to the width of the linear margin portion. The latent image and the background are configured such that the phase, pitch, or arrangement direction of each line is different from each other.

For example, in the latent image pattern 5, the lines constituting the latent image can be configured so that the pitch differs from 1/4 to 3/4 with respect to the lines constituting the background. Further, it is preferable that the pitch is different by 1/2. In this case, the visualization pattern 6 can be configured by a single line similar to the single line that configures the background. Note that since the latent image and the background are relative concepts, the visualization pattern can be configured by lines similar to the lines forming the latent image.

Also, the lines constituting the background can be configured so that the pitch is the same and the phase is 1/4 to 3/4 of the pitch with respect to the lines constituting the latent image. Further, it is preferable that the phase is different by 1/2. In this case, the visualization pattern can be constituted by a line similar to the line constituting the background. Note that since the latent image and the background are relative concepts, the visualization pattern can be configured by lines similar to the lines forming the latent image.

Alternatively, in the latent image pattern 5, the pitch of the lines constituting the latent image can be doubled with respect to the pitch of the lines constituting the background. Also in this case, the visualization pattern 6 can be composed of the same lines as the lines constituting the background, or can be composed of the same lines as the lines constituting the latent image.

Also, the latent image pattern 5 may be configured such that the direction of the lines constituting the background differs by 45 degrees from the direction of the lines constituting the latent image. In addition, since the arrangement direction of the lines is a direction orthogonal to the direction of the lines, by making the lines constituting the latent image different from the lines constituting the background by 45 degrees (shifting 45 degrees), The arrangement direction of the lines can be made different. Also in this case, the visualization pattern 6 can be composed of the same lines as the lines constituting the background, or can be composed of the same lines as the lines constituting the latent image.

Further, in the latent image pattern 5, as a periodic pattern constituting the latent image and the background, it is possible to use dots arranged in a line instead of the lines. In this case, the visualization pattern can be composed of a dot row similar to the dots constituting the background. In addition, the visualization pattern 6 can be configured by a line that can be overlapped with the dot row.

As shown in FIG. 2A, the latent image pattern 5 has a non-latent image portion (background) 5a composed of halftone dots having a uniform pitch, and the pitch is shifted by approximately ½ pitch with respect to the non-latent image portion 5a. And a latent image portion 5b composed of halftone dots. An image is formed by a set of respective halftone dots.
The latent image portion 5b may have an arbitrary shape such as a character, a picture, a symbol, or a pattern, and may be formed so as to be visible.

As shown in FIG. 2 (b), the visualization pattern 6 has a pitch equal to the pitch in the non-latent image portion (background) 5a, and coincides with the halftone dot sequence in the non-latent image portion (background) 5a. 6a.
Here, the pitch is an interval in the d direction shown in the figure.

When the latent image pattern 5 and the visualization pattern 6 are overlapped, as shown in FIG. 2C, the non-latent image portion (background) 5a and the line 6a overlap and coincide with each other. (Background) The latent image portion 5b shifted by a pitch ½ from the line 5a and the line 6a is visualized.

The latent image pattern 5 shown in FIG. 3 (a) is the same as the pattern shown in FIG. 2 (a). Also, the visualization pattern 6 shown in FIG. 3B is the same as the pattern shown in FIG.

When the latent image pattern 5 and the visualization pattern 6 are overlapped so that the latent image portion 5b and the line 6a overlap and coincide with each other, as shown in FIG. 3C, the non-latent image portion (background) 5a The lines 6a are alternately positioned with a pitch ½ to form a background, and a blank portion shifted by a pitch ½ of the latent image portion 5b is visualized as the same shape as the latent image portion 5b. Visible.

The display print area 7 shows display contents such as product information and can form a multicolored pattern in the entire area. In the latent image sheet 2 and the visualization sheet 3, the display contents of the display print area 7 may be the same or different. When performing these printings, an anchor coat that improves ink adhesion may be interposed between the ink layer of the image and the surface of the substrate 11.
The latent image pattern 5 can also be formed on the front surface of the back laminate 3.
Furthermore, the latent image portion 5b may be formed in an image having an arbitrary shape such as a character, a picture, a symbol, or a pattern.

As the laminates 2, 3, and 4, laminates usually used for soft packaging bags can be used. As the base material 11, paper, metal foil, a synthetic resin film, etc. which consist of one layer or multiple layers are used. For example, the low-density polyethylene resin (LDPE), the high-density polyethylene resin (HDPE), the linear low-density polyethylene resin (LLDPE), the polypropylene resin (PP), and the polyolefin-based elastomer that can be used as the transparent sheet 11a. Polyolefin resins such as polyethylene terephthalate resin (PET), polybutylene terephthalate resin (PBT), polyester resins such as polyethylene naphthalate resin (PEN), cellulose resins such as cellophane and cellulose triacetate (TAC), polymethyl Methacrylate (PMMA) resin, ethylene-vinyl acetate copolymer resin (EVA), ionomer resin, polybutene resin, polyacrylonitrile resin, polyamide resin, polystyrene resin (PS), polyvinyl chloride Resin (PVC), polyvinylidene chloride resin (PVDC), polycarbonate resin (PC), fluorine-based resin, synthetic resin films and paper, such as urethane resin, a metal foil or the like alone or be used in combination.
As described above, it is preferable that one of the laminates 2 and 3 is a transparent sheet.

In the manufacturing process of the packaging container 1 according to the present embodiment, as shown in FIG. 11, a sheet 1 b having laminated bodies 2 and 3 formed so as to be continuous at one upper end in a standing (standing) state is used.

The packaging container 1 which concerns on this embodiment is manufactured using the sheet | seat 1b in which the laminated bodies 2 and 3 continued as shown in FIG. 11 similarly to 6th Embodiment. A continuous long film has laminates 2 and 3 that are cut to form two packaging containers, respectively. Each form a filling opening 41, a dispensing nozzle seal 24, a dispensing nozzle 32, an opening notch 35, a side seal (seal) 22, and a bottom seal (seal) 23. It is cut along the contour.

In addition, in the sheet | seat 1a, as shown in FIG. 11, the laminated bodies 2 and 3 are formed so that it may continue in the up-down direction in the standing state at the time of the packaging container 1 being manufactured. Moreover, when it demonstrates taking the laminated body 3 as an example, as shown in FIG. 12, it forms so that it may continue in the lower part (bottom side) in the standing state at the time of the packaging container 1 being manufactured.

In the manufacturing method of the packaging container 1 according to the present embodiment, a latent image pattern region (latent image pattern) 5, a visualization pattern region (visualization pattern) 6, and a display print region 7 are formed on a sheet 1a shown in FIG. After printing using ink, the paper is folded at fold lines 8a and 8b to sandwich the laminated body 4 to be the bottom tape 4, and the dispensing nozzle seal portion 24, the side seal portion (seal portion) 22, and the bottom seal The part (seal part) 23 is sealed. Two folding lines 8a and 8b are set in the vicinity of the left and right width direction quarters of the sheet 1a in the vicinity of the filling opening 41 in each packaging container 1, and are substantially the same as the filling opening 41. Set to be parallel.

The left and right ends of the sheet 1a are folded back from the fold line 8a and the fold line 8b toward the center line 9, and after applying the above-mentioned seal or simultaneously with the seal, the sheet 1a is cut to a predetermined contour, and the standing (standing position) ) The packaging container 1 is continuous at the top in the state. Thereafter, the two packaging containers 1 are separated at the bottom 4 near the center line 9.

In this embodiment, the visualization pattern area (visualization pattern) 6 and the display print area 7 are provided at positions very close to the fold line 8a and the fold line 8b. In this way, the distance from the fold line 8a and the fold line 8b to the visualization pattern area (visualization pattern) 6 and the display print area 7 is short, so that the left and right ends of the sheet 1a from the fold line 8a and the fold line 8b to the center line 9. When folded back, the alignment between the visualization pattern region (visualization pattern) 6 and the display print region 7 is facilitated, and the occurrence of deviation can be prevented and accurate visualization can be performed in bag making. It becomes possible. Thereby, the yield in bag making can be improved.

The description is omitted.
In FIG. 15, (a) is an enlarged schematic view of the halftone dots constituting the image with the latent image pattern 5 as seen from above, and (b) is an enlarged schematic view of the lines constituting the visualization pattern 6 as seen from above. It is.

As shown in FIG. 15B, the latent image pattern 5 is composed of a non-latent image portion (background) 5a composed of halftone dots having a uniform pitch and a halftone dot having a pitch shifted with respect to the non-latent image portion 5a. And a latent image portion 5b. The line width M1 of each halftone dot and the line interval M2 of the halftone dot are set as follows.

As shown in FIG. 15 (a), the visualization pattern 6 has a pitch equal to the pitch in the non-latent image portion (background) 5a, and coincides with the halftone dot row in the non-latent image portion (background) 5a. 6a, and the line width M1 of each line and the interval M2 between lines are set as follows.
Here, the pitch is an interval in the d direction shown in the figure.

<Condition 1>
0.01mm ≦ M1 ≦ 0.15mm
0.01mm ≦ M2 ≦ 0.15mm

By setting it as the range of the above-mentioned line width M1, it is possible to reduce the possibility that the line width is too thin and the ink does not adhere to the plate and printing failure occurs. In addition, by setting the interval M2 in the above range, it is possible to prevent the interval from being too narrow and the ink from being crushed and being unable to be visualized.
Further, by setting the line width M1 and the interval M2 within the above ranges, it is possible to prevent the latent image pattern 5 and the visualization pattern 6 from being scanned and easily duplicated. Increasing the line width M1 and the interval M2 is not preferable because scanning may be easy.

<Condition 2>
0.03mm ≦ M1 ≦ 0.45mm
0.03mm ≦ M2 ≦ 0.45mm
0.2 ≦ (M2 / M1) ≦ 10

By setting it as the range of the above-mentioned line width M1, it is possible to reduce the possibility that the line width is too thin and the ink does not adhere to the plate and printing failure occurs. In addition, by setting the interval M2 in the above range, it is possible to prevent the interval from being too narrow and the ink from being crushed and being unable to be visualized.
Further, by setting the line width M1 and the interval M2 within the above ranges, it is possible to prevent the latent image pattern 5 and the visualization pattern 6 from being scanned and easily duplicated.
Further, by setting the line width M1 and the interval M2 and the ratio thereof within the above ranges, it is possible to prevent the latent image pattern 5 and the visualization pattern 6 from being scanned and easily produce a duplicate. Increasing the line width M1, the interval M2, and the ratio M2 / M1 is not preferable because it may facilitate scanning.

These data are listed in Table 1.
The conditions are the same as in the examples described later.

In Table 1,
A: Reproducibility and security C: No security, printing not possible, or no reproducibility.

In the present embodiment, since the parameters are set as described above, it becomes possible to prevent forgery by others and to manufacture a clear latent image so as to be visible.
Here, in the printing process of the latent image pattern 5 and the visualization pattern 6, as shown in FIG. 16A, when the screenless plate P1 having no bank crossing in the width direction in the thin line is used, the line width M1 Is too thin, the ink overflows and the line width M1 may not be set accurately. Therefore, it is preferable to set it in the range of the line width M1.

Further, in the printing process of the latent image pattern 5 and the visualization pattern 6, as shown in FIG. 16B, when the cell plate P2 having a cylinder cell for holding ink is used, the line width M1 is too thin. There is a possibility that the predetermined line width M1 cannot be set accurately because the ink does not stick to the plate. Therefore, it is preferable to set it in the range of the line width M1. At the same time, if the width of the interval M2 is narrow, the ink is crushed and cannot be visualized. Therefore, the interval M2 is preferably set in the range.

In each of the above embodiments, the difference in size between the latent image pattern 5 and the visualization pattern 6 is increased, that is, the latent image pattern 5 is formed larger than the visualization pattern 6, or the visualization pattern 6 is By forming the image larger than the latent image pattern 5, even if a positional deviation occurs between the latent image sheet 2 and the visualization sheet 3 and a pitch deviation occurs, the latent image pattern 5 and the visualization pattern 6 are overlapped to form a latent image. Realization is possible.
Thereby, not only when the latent image pattern 5 and the visualization pattern 6 are separated from the seal portions 22, 23, and 24, but also by increasing either the latent image pattern 5 or the visualization pattern 6, the latent image pattern 2 and the visualization pattern 6 are visualized. An image can be formed even if the position of the sheet 3 is slightly shifted.

Next, examples in the present embodiment will be described.

Using a gravure printing machine, a low-density polyethylene resin was prepared as the sheet 1a, the printing conditions were set as follows, the latent image pattern 5 and the visualization pattern 6 were printed, and the reproducibility of the manifestation was confirmed.
<Printing conditions>
・ Gravure printing type (screenless version, cell version)
-Printing speed (traveling speed of sheet 1a; m / min)
・ Ink viscosity (CPS: centipoise = mPa · s)
・ Line width M1 (mm)
・ Interval M2 (mm)
・ M2 / M1 (ratio)
These conditions are shown in Table 2, and the results are shown in Table 3.

Note that the reproducibility of the manifestation can be confirmed by visual inspection if the manifested characters / symbols cannot be judged by “no reproducibility”, when the copy machine can be scanned by “no security”, It was judged that “printing is not possible” when an abnormality was found in the pattern by visual inspection before it became apparent.

In Table 3,
A: With reproducibility / security B: No reproducibility problem (inferior to A), with security C: No security, or non-visualization.

Therefore, in the case of gravure printing, the line width M1 within a range that can be reproducible for visualization and secures security is 0.01 mm ≦ M1 ≦ 0.15 mm for both the latent image pattern 5 and the visualization pattern 6.
And the ratio of the line width M1 and the interval M2 is 0.5 ≦ (M2 / M1) ≦ 2.
It can be seen that it is preferable to be in the range.
In the screenless plate, ink overflowed under all conditions, making it impossible to visualize the image. However, if the ink and machine conditions were reviewed and printing was possible under the above conditions, print with the screenless plate. You can also

From these results, by providing conditions such as the line width M1, the interval M2, and the ratio within the above ranges, it is possible to provide a packaging container that can ensure the reproducibility of the latent image while maintaining security. Is possible.

State is maintained. When the engagement relationship between the locking piece 67 and the locking piece 68 is released, the container upper part 55 comes to rise due to the restoring force generated at the container folding portion of the main body surface laminate 52 and the main body back surface laminate 53, The stored item extraction path 60 is not blocked.

In the packaging container 51 of the present embodiment, a device for facilitating formation of a spout for pouring out the stored item from the stored item extraction path 60 is provided. In other words, a device is devised that facilitates manual cutting along the position of the spout formation scheduled portion 61 at the distal end portion of the stored item pouring path 60. First, in the center of the container upper portion 55, there is a vertical cut line portion 69 formed of a discontinuous slit extending downward from the upper edge of the container upper portion and reaching the seal boundary portion 62. Further, there is an inclined cut portion 70 formed of a slit that is continuous with the lower end of the longitudinal cut line portion 69 and is parallel to the seal boundary portion 62 and reaches the end portion of the spout formation portion 61.

After the vertical cut line portion 69 is cut vertically, the other piece in the container width direction is gripped while holding the tongue-like portion formed between the position of the cut vertical cut line portion 69 and the inclined cut line portion 70. By pulling toward the container side part 58 side, the spout forming part 61 is torn and the spout 71 (FIG. 17B) is easily formed.

In the packaging container 51 according to the present embodiment, the main body surface laminate 52 is provided with a latent image pattern region (latent image pattern) 75 and a visualization pattern region (visualization pattern) 76, as shown in FIG. 17A. Yes. In the present embodiment, the latent image pattern region 75 and the visualization pattern region 76 are formed so as not to overlap the stored items at positions symmetrical to the planned bending portion 64, and the container upper portion 55 is bent downward. In this case, an authentication set is formed so that the latent images can be visually recognized by overlapping each other. Each of these patterns is printed using ink. In the main body front surface laminate 52 and the main body back 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 the above embodiments can be used similarly.

In order to close the stored item extraction path 60 opened as described above, the container is bent from the position of the planned folding portion 64 as shown in FIG. 68 can be engaged with each other, and the operation of closing the stored item extraction path 60 is also easy. Further, when the stored item extraction path 60 is closed, it is possible to perform authenticity determination using an additional authentication set.

The packaging container of the present invention can be used for foods, non-foods, pharmaceuticals, luxury goods and the like.
