FIG. 1 is a schematic perspective view of a packaging container according to an embodiment of the present invention. In FIG. 1, the packaging container 1 has a box body 10, a three-dimensional object 20, a transparent plate (clear card) 30, and a lid body 40. By accommodating goods or articles (not shown) such as sweets and toys together with the three-dimensional object 20 and the transparent plate 30 in the box body 10 and covering the box body 10 with a lid 40 from above, various products and the like can be obtained. It can be a packaging container 1.

The box body 10 includes a bottom wall 11 on which the three-dimensional object 20 is placed, a back wall 12 arranged on the back side of the three-dimensional object, and both side walls 13 extending forward from the back wall 12 on both sides of the three-dimensional object 20. 13 and. The box body 10 is formed with an upper opening 15 facing the bottom wall 11 and a front opening 16 facing the back wall 12. If the packaging container 1 is not configured, the bottom wall 11 and the back wall 12 are unnecessary. In the present embodiment, the box body 10 further has a front wall 14 facing the back wall 12. The front wall 14 has two side edge walls 14A and 14B arranged on both sides of the front opening 16 and defining the opening width of the front opening 16. The front wall 14 may further have a lower edge wall 14C that stands up from the bottom wall 11 and defines the lower end of the front opening 16.

The height L1 of the box body 10 is lower than the length L2 of the transparent plate 30 (L1 <L2). The height L3 of the lid 40 is higher than the length L2 of the transparent plate 30 (L1 <L2 <L3). In this way, the transparent plate 30 can be leaned against the inside of the box body 10 and the box body 10 can be covered with the lid body 40 from above. For example, the lid body 40 has a shape of a lid box body having an open lower end, and the lid body 40 is attached to the box body 10 by bending the folded pieces 41 and 41 and attaching them to the bottom wall 11 of the box body 10 with an adhesive tape or the like. Can be fixed.

The three-dimensional object 20 is a three-dimensional object having irregularities on the front surface as shown in FIG. 2, and an example shown in FIG. 2 is a three-dimensional object of a building. The three-dimensional object 20 is not limited to a building, and may be various characters or figures. The three-dimensional object 20 may be made of resin, metal, paper craft, or the like. The three-dimensional object 20 may be fixed to the back wall 12 of the box body 10, or the three-dimensional object 20 taken out from the packaging container 1 may be arranged back to back with the back wall 12.

The transparent plate 30 is formed in a thin plate shape with glass, resin, or the like, which is a material transparent to the wavelength band of visible light. From the viewpoint of resistance to breakage and weight reduction, it is preferable to form the transparent plate 30 from a molded body of a resin such as polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC), or acrylic. As shown in FIG. 3, the transparent plate 30 has the lower end portion 32 located in front of the upper end portion 31 between the side walls 13 and 13 of the box body 10 and in front of the three-dimensional object 20. It is arranged so as to be inclined (for example, an inclination angle = 45 °).

An installation portion 21 on which the upper end portion 31 of the transparent plate 30 can be placed is formed on the upper surface of the three-dimensional object 20. The installation portion 21 is formed as an inclined surface that is inclined downward toward the front, for example. By providing such an installation unit 21, the angle of the transparent plate 30 is positioned so as to superimpose the image of the display unit 110 at the surface position of the three-dimensional object 20 seen through the transparent plate 30, and the transparent plate 30 is used. It is possible to provide a person with a clearer image. In the present embodiment, the installation portion is an inclined surface that is inclined downward toward the front, but the positioning is such that the image of the display portion 110 is superimposed on the surface position of the three-dimensional object 20 that is seen through the transparent plate 30. If possible, the position and shape of the installation part is not limited to this. For example, an installation portion capable of fixing the upper end portion 31 of the transparent plate 30 may be provided on the front surface of the three-dimensional object 20, or an installation portion may be provided on the box body. Further, as shown in FIGS. 2 and 3, two side stoppers 22 and 22 projecting upward at both ends in the width direction of the installation portion 21 can be further provided on the upper surface of the three-dimensional object 20. The two side stoppers 22 and 22 can position the transparent plate 30 in the width direction. The side stopper may be provided on the box body. As shown in FIG. 3, the lower end portion 32 of the transparent plate 30 is locked at the intersection angle portion between the bottom wall 11 of the box body 10 and the front wall 14 (14A to 14C).

3 and 5 show an image display device in which a mobile terminal (for example, a smartphone) 100 having a display unit 110 shown in FIG. 6 is erected on both side walls 13 and 13 of the box body 10 with the display unit 110 facing downward. Indicates the usage status of. The image display device is configured by assembling the box body 10, the three-dimensional object 20, and the transparent plate 30 excluding the lid 40 from the members shown in FIG. 1 as shown in FIGS. 3 and 5. FIG. 7 shows an example of image display observed from the front opening 16 in the state of use of the image display devices shown in FIGS. 3 and 5. The mobile terminal may be supported by a box body, and can be supported by at least two wall surfaces of the side walls 13, 13, the back wall 12, and the front wall 14.

As shown in FIG. 3, the image display device according to the present embodiment is a mobile terminal that is reflected by the transparent plate 30 on the fluoroscopic stereoscopic image Im1 of the stereoscopic object 20 that is incident from behind the transparent plate 30 and is seen through. The image Im2 of the display unit 110 of 100 is superimposed. At this time, the reason why the transparent plate 30 functions as a half mirror is considered as follows. Since the rear side of the transparent plate 30 on which the three-dimensional object 20 is arranged is surrounded by the three-dimensional object 20, both side walls 13, 13 and the mobile terminal 100, it is darker than the front opening 16 side in front of the transparent plate 30. .. The transparent plate 30 functions as a half mirror for an observer who directly looks at the three-dimensional object 20 (from the bright side) from the front opening 16 side (from the bright side) in front of the transparent plate 30. The half-mirror effect of the transparent plate 30 is similar to the phenomenon in which one's face reflected by the car window is superimposed on the scenery seen through the car window at night. Since the transparent plate 30 is arranged at an angle, the image of the display unit 110 can be reflected and displayed to the observer. As described above, according to the image display device of the present embodiment, the three-dimensional object 20 which is transparent through the transparent plate 30 with a relatively high transmittance is reflected by the transparent plate 30 without using a half mirror. The image of the display unit 110 can be superimposed.

Here, the transparent plate 30 can be configured by laminating a plurality of transparent thin plates 30A to 30C as shown in FIG. 4, which is an enlarged view of part A in FIG. By doing so, each interface between the plurality of transparent thin plates 30A, 30B, and 30C becomes a reflective layer, and the reflectance can be increased. Further, since the transmittance is lowered as a result of the increase in the reflectance in this way, the space behind the transparent plate 30 becomes darker, and the half mirror effect of the transparent plate 30 is enhanced. As shown in FIG. 8B, the two transparent thin plates 30A and 30B are more than the reflection image 121 in which the image 120 of the display unit 110 is reflected by one transparent thin plate 30A as shown in FIG. 8 (A). The reflected image 122 that reflects the image 120 of the display unit 110 becomes clearer.

Here, the thickness of each of the plurality of transparent thin plates 30A to 30C can be 0.45 mm or less. If it is thicker than that, as shown in FIG. 4, misalignment occurs between the reflected images at different interfaces, and the blur of the composite reflected image becomes conspicuous. When the transparent plate 30 is molded of resin, the thickness of each of the transparent thin plates 30A to 30C can be 0.15 to 0.45 mm in consideration of moldability.

Further, the number of laminated transparent thin plates is preferably 2 to 4 in consideration of the above-mentioned thickness, and even if the number of laminated transparent plates increases from the upper limit, misalignment occurs between the reflected images at different interfaces, and the composite reflected image Blurring is noticeable.

The transparent plate 30 or the plurality of transparent thin plates 30A to 30C may be colored, for example, gray. By coloring the transparent plate 30 or the plurality of transparent thin plates 30A to 30C, the transmittance of the transparent plate 30 or the plurality of transparent thin plates 30A to 30C is lowered, and the space behind the transparent plate 30 or the plurality of transparent thin plates 30A to 30C is reduced. By darkening, the transmittance of the transparent plate 30 can be increased.

When the plurality of transparent thin plates 30A to 30C are fixed in a laminated state, the handleability is improved. The plurality of transparent thin plates 30A to 30C can be welded (including ultrasonic welding), bonded, crimped, or fixed by a frame, for example.

The image displayed on the display unit 110 of the mobile terminal 100 shown in FIG. 6 may be a still image, but may also be a moving image. For example, on the display unit 110, a still image image 120A colored with the same contour as the front image of the three-dimensional object 20 and a moving image 120B whose display position, shape, color, etc. change with time are displayed as a background stereoscopic image 120B. It is projected and displayed on the object 20. By doing so, by superimposing the image of the display unit 110 including the moving image on the stationary three-dimensional object image seen through the transparent plate 30, the front opening 16 of the image display device shown in FIG. 7 can be diversified as if it were a 3D hologram. It is possible to simulate the produced image (for example, an image in which a three-dimensional object is moving).

As shown in FIG. 7, the viewing angle of the front opening 16 of the image display device is limited by the side edge walls 14A and 1B on both sides. Therefore, even if the display unit 110 of the mobile terminal 100 is, for example, a liquid crystal display unit, it can be adapted to the viewing angle of the liquid crystal display unit. Further, since the front opening 16 of the image display device limits the field of view by the side edge walls 14A and 1B and the lower edge wall 14C, unnecessary backgrounds such as the bottom wall 11 and the side wall 13, 13 of the box body 10 can be used. Can be blindfolded.

A marker is provided on the box body 10, the three-dimensional object 20, or the display unit 110 in order to superimpose the image of the display unit 110 of the mobile terminal 100 on the three-dimensional object 20 and to align the mobile terminal 100 with respect to the box body 10. be able to. In FIGS. 1 to 3, a marker 23 is provided on the upper surface of the three-dimensional object 20, for example, at the center in the width direction. The marker 23 can be aligned with the center line of the display unit 110 of the mobile terminal 100.

FIG. 9 shows markers 130 to 133 displayed on the display unit 110 of the mobile terminal 100. The marker 130 can be displayed at a position corresponding to the marker 23 provided on the three-dimensional object 20. The marker 131 is aligned with the side walls 13 and 13 of the box body 10. The marker 132 is aligned with the back wall 12 of the box body 10. The marker 133 is aligned with the side edge walls 14A and 14B of the box body 10. The display unit 110 can display any one or more of the markers 130 to 133.

As shown in FIG. 10, the base station 210 communicated with the mobile terminal 100 is connected to the server 220 via the network 200. As shown in FIG. 11, the mobile terminal 100 has an acquisition unit 150 connected to the camera 140 shown in FIG. 9 in addition to the display unit 110. The camera 140 of the mobile terminal 100 captures a QR code (registered trademark) 17, which is a two-dimensional code provided on the box body 10 shown in FIG. 1, and the code information is acquired by the acquisition unit 150. The mobile terminal 100 further includes an input unit 160 such as an icon displayed on the display unit 110, and a communication unit 170. The communication unit 170 communicates with the server 220 based on the URL which is the access information of the server 220 included in the QR code (registered trademark) 17.

As shown in FIG. 12, the server 220 includes a communication unit 221 and a storage unit 222. For the mobile terminal 100 accessed based on the QR code (registered trademark) 17, the server 220 executes the following steps 1 and 2 based on the program in the storage unit 222. As step 1, the data of at least one marker image of the markers 130 to 133 shown in FIG. 9 is read from the storage unit 222 and transmitted to the mobile terminal 100 via the communication unit 221 and the network 200 and the base station 210. As step 2, the data of the images 120A and 120B shown in FIG. 6 is read from the storage unit 222 and transmitted to the mobile terminal 100 via the communication unit 221 and the network 200 and the base station 210.

The server 220 can display the marker image of step 1 on the display unit 110 of the mobile terminal 100 for an initial predetermined time, and then move to step 2. That is, after the mobile terminal 100 is aligned based on the markers 130 to 133 displayed in step 1, the markers 130 to 133 are not displayed. Instead, the server 220 can display the marker image of step 1 on the display unit 110 of the mobile terminal 100 for an initial predetermined time, and then carry out steps 1 and 2 in parallel. That is, the marker image is displayed as an initial image, and may be continuously displayed together with the images 120A and 120B shown in FIG.

The embodiment of the present invention is not limited to the above embodiment, and components can be added, omitted, or changed as appropriate.

For example, as shown in FIG. 1, the lid 40 is not limited to the one provided separately from the box 10. The box body 10A shown in FIG. 13 may also have a first lid body 42 covering the upper opening 15 and a second lid body 43 covering the front opening 16 integrally with the box body 10A. The first and second lids 42 and 43 are connected to the box body 10A by, for example, a sewing machine wire that can be cut, and are separated from the box body 10A at the time of use.

As shown in FIG. 14, since the box body 10A has the same height L3 as the lid body 40 shown in FIG. 1, the transparent plate 30 having a length L2 (see FIG. 1) can be accommodated in the box body 10A in a vertical state. .. Further, as shown in FIG. 14, the installation portion for installing the upper end portion 31 of the transparent plate 30 may be the back wall 12A of the box body 10A instead of the three-dimensional object 20.
