DETAILED DESCRIPTION OF THE INVENTION
[0019] 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. Inside the box body 10, together with the three-dimensional object 20 and the transparent plate 30, a product or an article (not shown) such as a snack or a toy is accommodated, and by covering the box body 10 with the lid body 40 from above, the packaging container 1 for various products and the like can be obtained.
[0020] The box body 10 has a bottom wall 11 on which the three-dimensional object 20 is placed, a rear wall 12 arranged on the back side of the three-dimensional object, and both side walls 13, 13 extending forward from the rear wall 12 on both sides of the three-dimensional object 20. In the box body 10, an upper opening 15 facing the bottom wall 11 and a front opening 16 facing the rear wall 12 are formed. When not constituting the packaging container 1, the bottom wall 11 and the rear wall 12 are unnecessary. In the present embodiment, further, the box body 10 further has a front wall 14 facing the rear wall 12. The front wall 14 has two side edge walls 14A, 14B arranged on both sides of the front opening 16 and defining the opening width of the front opening 16. The front wall 14 can further have a lower edge wall 14C standing up from the bottom wall 11 and defining the lower end of the front opening 16.
[0021] 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 body 40 is higher than the length L2 of the transparent plate 30 (L1 < L2 < L3). Thus, the transparent plate 30 can be leaned inside the box body 10, and the box body 10 can be covered with the lid body 40 from above. The lid body 40 has, for example, the shape of a lid box body with an open lower end, and by bending the bent pieces 41, 41 and bonding them to the bottom wall 11 of the box body 10 with an adhesive tape or the like, the lid body 40 can be attached and fixed to the box body 10.
[0022] As shown in FIG. 2, the three-dimensional object 20 is a three-dimensional object having irregularities on the front surface, and the 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, or paper craft. The three-dimensional object 20 may be fixed to the rear 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 rear wall 12.
[0023] The transparent plate 30 is formed in a thin plate shape from a material that is transparent to the wavelength band of visible light, such as glass or resin. From the viewpoints of being difficult to break 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 is inclined (for example, the inclination angle = 45°) and arranged between the both side walls 13, 13 of the box body 10 and in front of the three-dimensional object 20 such that the lower end portion 32 is positioned forward of the upper end portion 31.
[0024] 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, for example, as an inclined surface that slopes downward as it goes forward. By providing such an installation portion 21, the angle of the transparent plate 30 is positioned so as to superimpose the image of the display portion 110 at the surface position of the three-dimensional object 20 seen through the transparent plate 30, and a cleaner image can be provided to the user. In the present embodiment, an inclined surface that slopes downward as it goes forward is used as the installation portion. However, the position and shape of the installation portion are not limited to this as long as the positioning for superimposing the image of the display portion 110 is possible at the surface position of the three-dimensional object 20 seen through the transparent plate 30. 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, 22 that protrude upward may be further provided at both ends in the width direction of the installation portion 21 on the upper surface of the three-dimensional object 20. These two side stoppers 22, 22 can position the transparent plate 30 in the width direction. Note that the side stoppers may be provided on the box body. The lower end portion 32 of the transparent plate 30 is locked at the intersection corner portion of the bottom wall 11 and the front wall 14 (14A to 14C) of the box body 10 as shown in FIG. 3.
[0025] Figures 3 and 5 show the usage state of a video display device in which a mobile terminal (e.g., a smartphone) 100 having a display unit 110 shown in Fig. 6 is installed on both side walls 13, 13 of the box body 10 with the display unit 110 facing downward. The video display device is configured by assembling the box body 10, the three-dimensional object 20, and the transparent plate 30, excluding the lid body 40 among the members shown in Fig. 1, as shown in Figs. 3 and 5. Fig. 7 shows an example of a video display observed from the front opening 16 in the usage state of the video display device shown in Figs. 3 and 5. Note that the mobile terminal only needs to be supportable by the box body, and can be supported by at least two wall surfaces among the two side walls 13, 13, the rear wall 12, and the front wall 14.
[0026] As shown in Fig. 3, the video display device according to the present embodiment superimposes the video Im2 of the display unit 110 of the mobile terminal 100 reflected by the transparent plate 30 on the perspective three-dimensional video Im1 of the three-dimensional object 20 that is incident from behind the transparent plate 30 and is seen through. At this time, the reason why the transparent plate 30 functions as a half mirror is considered as follows. Since the rear of the transparent plate 30 where the three-dimensional object 20 is arranged is surrounded by the three-dimensional object 20, the two side walls 13, 13, and the mobile terminal 100, it becomes darker compared to the front opening 16 side in front of the transparent plate 30. To an observer who directly views the three-dimensional object 20 from the front opening 16 side in front of the transparent plate 30 (from the bright side) (towards the dark side), the transparent plate 30 functions as a half mirror. This half mirror effect by the transparent plate 30 is the same as the phenomenon in which the scenery seen through the car window at night is superimposed with one's own face reflected by the car window. Since the transparent plate 30 is arranged in an inclined manner, the video of the display unit 110 can be reflected and displayed to the observer. Thus, according to the video display device of the present embodiment, even without using a half mirror, the video of the display unit 110 reflected by the transparent plate 30 can be superimposed on the three-dimensional object 20 that is seen through via the transparent plate 30 with a relatively high transmittance.
[0027] Here, as shown in FIG. 4 which is an enlarged view of part A in FIG. 3, the transparent plate 30 can be configured by laminating a plurality of transparent thin plates 30A to 30C. In this way, each interface between the plurality of transparent thin plates 30A, 30B, and 30C becomes a reflective layer, and the reflectance can be increased. Also, as a result of the increase in reflectance in this way, the transmittance decreases, so 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. 8(B), the reflected image 122 obtained by reflecting the image 120 of the display unit 110 with two transparent thin plates 30A and 30B is clearer than the reflected image 121 obtained by reflecting the image 120 of the display unit 110 with a single transparent thin plate 30A as shown in FIG. 8(A).
[0028] 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, displacement occurs between the reflected images at different interfaces, and the blurring of the combined reflected image becomes prominent. When the transparent plate 30 is molded from resin, considering the moldability, the thickness of each of the transparent thin plates 30A to 30C can be 0.15 to 0.45 mm.
[0029] Also, considering the above-mentioned thickness, the number of laminated transparent thin plates is preferably 2 to 4. Even when the number of laminated plates exceeds the upper limit, displacement occurs between the reflected images at different interfaces, and the blurring of the combined reflected image becomes prominent.
[0030] The transparent plate 30 or the plurality of transparent thin plates 30A to 30C may be colored, for example, in gray or the like. 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 darkened, thereby increasing the reflectance of the transparent plate 30.
[0031] Fixing the plurality of transparent thin plates 30A to 30C in a laminated state improves the handleability. The plurality of transparent thin plates 30A to 30C can be fixed, for example, by welding (including ultrasonic welding), adhesion, pressure bonding, or by a frame.
[0032] The video displayed on the display unit 110 of the mobile terminal 100 shown in FIG. 6 may be a still image, but can also be a moving image. For example, on the display unit 110, together with the still image video 120A colored with the same contour as the front view of the three-dimensional object 20, a video 120B of a moving image whose display position, shape, color, etc. change over time is projection-mapped onto the three-dimensional object 20 which is the background and displayed. By doing so, by superimposing the video 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 video display device shown in FIG. 7 can pseudo-reproduce a video (for example, a video where the three-dimensional object appears to be moving) colorfully produced as if it were a 3D hologram.
[0033] As shown in FIG. 7, the viewing angle of the front opening 16 of the video display device is restricted by the side edge walls 14A and 14B 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. Also, since the front opening 16 of the video display device restricts the viewing field by the side edge walls 14A and 14B and the lower edge wall 14C, unnecessary backgrounds such as the bottom wall 11 and the side walls 13 and 13 of the box body 10 can be blocked from view.
[0034] In order to superimpose the video of the display unit 110 of the mobile terminal 100 on the three-dimensional object 20, markers can be provided on the box body 10, the three-dimensional object 20, or the display unit 110 to align the mobile terminal 100 with the box body 10. In FIGS. 1 to 3, a marker 23 is provided, for example, at the center in the width direction on the upper surface of the three-dimensional object 20. The center line of the display unit 110 of the mobile terminal 100 can be aligned with this marker 23.
[0035] 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 both side walls 13, 13 of the box body 10. The marker 132 is aligned with the rear wall 12 of the box body 10. The marker 133 is aligned with the side edge walls 14A, 14B of the box body 10. The display unit 110 can display any one or more of the markers 130 to 133.
[0036] As shown in FIG. 10, a base station 210 communicating with the mobile terminal 100 is connected to a server 220 via a network 200. As shown in FIG. 11, the mobile terminal 100 has, in addition to the display unit 110, an acquisition unit 150 connected to the camera 140 shown in FIG. 9. The camera 140 of the mobile terminal 100 captures an image of 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 a URL which is access information of the server 220 included in the QR code (registered trademark) 17.
[0037] 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 procedures 1 and 2 based on a program in the storage unit 222. As procedure 1, 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, the network 200, and the base station 210. As procedure 2, data of the videos 120A, 120B shown in FIG. 6 is read from the storage unit 222 and transmitted to the mobile terminal 100 via the communication unit 221, the network 200, and the base station 210.
[0038] Server 220 can cause the marker image in Step 1 to be displayed on the display unit 110 of the mobile terminal 100 for an initial predetermined period of time, and then proceed 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, server 220 can cause the marker image in Step 1 to be displayed on the display unit 110 of the mobile terminal 100 for an initial predetermined period of time, and then perform Steps 1 and 2 in parallel. That is, in addition to being displayed as an initial image, the marker image may continue to be displayed together with the videos 120A and 120B shown in FIG. 6.
[0039] Note that the form of the present invention is not limited to the above-described embodiment, and components can be added, omitted, or modified as appropriate.
[0040] For example, as shown in FIG. 1, the lid 40 is not limited to being provided separately from the box body 10. The box body 10A shown in FIG. 13 can also integrally include a first lid 42 that covers the upper opening 15 and a second lid 43 that covers the front opening 16. The first and second lids 42 and 43 are connected to the box body 10A by, for example, a sewing thread or the like that can be cut, and are separated from the box body 10A during use.
[0041] As shown in FIG. 14, since the box body 10A has the same height L3 as the lid 40 shown in FIG. 1, the transparent plate 30 having a length L2 (see FIG. 1) can be vertically accommodated in the box body 10A. Further, as shown in FIG. 14, the installation portion for installing the upper end portion 31 of the transparent plate 30 can be the back wall 12A of the box body 10A instead of the three-dimensional object 20.
