[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-122695 Summary of the Invention [Problem to be solved by the invention]

[0004] The half mirror used in the imaging device of Patent Document 1 is manufactured by depositing a metal reflective layer of chrome, SUS, or the like, thin enough to be semi-transparent, on at least one side of glass. Therefore, the half mirror is relatively expensive.

[0005] Patent Document 1 exemplifies a half mirror with a reflectance of 50% and a transmittance of 50%. Although these values ​​are only an example, half mirrors generally have a metal reflective layer, which reduces the transmittance of the background image.

[0019] Fig. 1 is a schematic perspective view of a packaging container according to one 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. The box body 10 can be used as a packaging container 1 for various products, etc., by storing goods or articles (not shown) such as sweets or toys together with the three-dimensional object 20 and the transparent plate 30 in the box body 10 and covering the box body 10 from above with the lid body 40.

[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. Note that 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 bending 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 with its back against the rear wall 12.

[0023] The transparent plate 30 is formed in a thin plate shape from glass, resin, or the like, which is a material transparent to the wavelength band of visible light. From the viewpoints of resistance to breakage and weight reduction, it is preferable to form the transparent plate 30 from a molded body of resin such as polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC), or acrylic. As shown in Fig. 3, the transparent plate 30 is disposed between both side walls 13, 13 of the box body 10, forward of the three-dimensional object 20, and inclined (for example, at an inclination angle of 45°) so that the lower end 32 is located forward of the upper end 31.

[0024] The upper surface of the three-dimensional object 20 is provided with a mounting section 21 on which the upper end 31 of the transparent plate 30 can be placed. The mounting section 21 is formed, for example, as an inclined surface that slopes downward toward the front. By providing such a mounting section 21, the angle of the transparent plate 30 is positioned so that the image of the display unit 110 is superimposed on the surface position of the three-dimensional object 20 seen through the transparent plate 30, and a clearer image can be provided to the user. In this embodiment, the mounting section is an inclined surface that slopes downward toward the front, but the position and shape of the mounting section are not limited to this as long as the positioning is possible so that the image of the display unit 110 is superimposed on the surface position of the three-dimensional object 20 seen through the transparent plate 30. For example, a mounting section on which the upper end 31 of the transparent plate 30 can be fixed may be provided on the front surface of the three-dimensional object 20, or the mounting section may be provided on a box body. In addition, as shown in FIG. 2 and FIG. 3, two side stoppers 22, 22 protruding upward at both ends in the width direction of the mounting section 21 may be further provided 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. The side stoppers may be provided on the box body. The lower end portion 32 of the transparent plate 30 is engaged at the intersection corner between the bottom wall 11 and the front wall 14 (14A to 14C) of the box body 10, as shown in FIG.

[0025] 3 and 5 show a state 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 a box body 10 with the display unit 110 facing downward. The image display device is constructed 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 an image display observed from the front opening 16 in the use state of the image display device shown in FIGS. 3 and 5. Note that the mobile terminal only needs to be supported by the box body, and can be supported by at least two wall surfaces among the both side walls 13, 13, the back wall 12, and the front wall 14.

[0026] As shown in FIG. 3, the image display device according to this embodiment superimposes an image Im2 of the display unit 110 of the mobile terminal 100 reflected by the transparent plate 30 on a perspective three-dimensional image Im1 of the three-dimensional object 20 that is incident from behind the transparent plate 30 and seen through. In this case, the reason why the transparent plate 30 functions as a half mirror is considered as follows. The rear of the transparent plate 30 where 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, and is darker than the front opening 16 side in front of the transparent plate 30. For an observer who looks directly at the three-dimensional object 20 (from the bright side) from the front opening 16 side in front of the transparent plate 30 (from the bright 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 one's own 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. In this way, according to the image display device of this embodiment, the image of the display unit 110 reflected by the transparent plate 30 can be superimposed on the three-dimensional object 20, which is viewed through the transparent plate 30 with a relatively high transmittance, without using a half mirror.

[0027] Here, the transparent plate 30 can be constructed 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. 3. 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. In addition, since the transmittance decreases as a result of the increase in 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. 8(B), a reflected image 122 in which the image 120 of the display unit 110 is reflected by two transparent thin plates 30A and 30B is clearer than a reflected 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).

[0028] Here, the thickness of each of the multiple thin transparent plates 30A-30C can be 0.45 mm or less. If it is thicker than that, a position shift occurs between the reflected images at different interfaces as shown in Fig. 4, and the blur of the composite reflected image becomes noticeable. When the transparent plate 30 is molded from resin, the thickness of each of the thin transparent plates 30A-30C can be 0.15-0.45 mm, taking moldability into consideration.

[0029] In addition, taking into consideration the thickness mentioned above, it is preferable that the number of laminated transparent thin plates is 2 to 4. If the number of laminated plates is increased beyond the upper limit, misalignment will occur between the reflected images at different interfaces, and the blurring of the composite reflected image will become noticeable.

[0030] The transparent plate 30 or the plurality of thin transparent plates 30A to 30C may be colored, for example, gray, etc. By coloring the transparent plate 30 or the plurality of thin transparent plates 30A to 30C, the transmittance of the transparent plate 30 or the plurality of thin transparent plates 30A to 30C can be reduced and the space behind the transparent plate 30 or the plurality of thin transparent plates 30A to 30C can be darkened, thereby increasing the reflectance of the transparent plate 30.

[0031] The plurality of transparent thin plates 30A to 30C can be fixed in a stacked state to improve ease of handling. 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 image displayed on the display unit 110 of the mobile terminal 100 shown in Fig. 6 may be a still image, but it can also be a moving image. For example, a moving image 120B, whose display position, shape, color, etc. change over time, is projected onto the three-dimensional object 20 as a background, along with a still image 120A colored with the same contour as the front image of the three-dimensional object 20, and is displayed on the display unit 110. In this way, by superimposing the image of the display unit 110 including the moving image on the still three-dimensional object image seen through the transparent plate 30, it is possible to reproduce a colorfully presented image (e.g., an image in which the three-dimensional object is moving) as if it were a 3D hologram in the front opening 16 of the image display device shown in Fig. 7.

[0033] 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, 1B on both sides. Therefore, even if the display unit 110 of the mobile terminal 100 is, for example, a liquid crystal display unit, the viewing angle can be adapted to that of the liquid crystal display unit. In addition, since the viewing angle of the front opening 16 of the image display device is limited by the side edge walls 14A, 1B and the lower edge wall 14C, unnecessary background such as the bottom wall 11 and both side walls 13, 13 of the box body 10 can be hidden.

[0034] 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 10, a marker can be provided on the box 10, the three-dimensional object 20, or the display unit 110. In Figs. 1 to 3, a marker 23 is provided on the top surface of the three-dimensional object 20, for example, at the center in the width direction. The marker 23 can be aligned so that the center line of the display unit 110 of the mobile terminal 100 coincides with the center line.

[0035] 9 shows markers 130 to 133 displayed on display unit 110 of mobile terminal 100. Marker 130 can be displayed at a position corresponding to marker 23 provided on three-dimensional object 20. Marker 131 is aligned with both side walls 13, 13 of box 10. Marker 132 is aligned with rear wall 12 of box 10. Marker 133 is aligned with side edge walls 14A, 14B of box 10. Display unit 110 can display one or more of markers 130 to 133.

[0036] As shown in Fig. 10, a base station 210 with which the mobile terminal 100 communicates is connected to a server 220 via a network 200. As shown in Fig. 11, the mobile terminal 100 has an acquisition unit 150 connected to a camera 140 shown in Fig. 9 in addition to a display unit 110. 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 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 for 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. In 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. In procedure 2, data of the videos 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, the network 200, and the base station 210.

[0038] The server 220 can display the marker image of procedure 1 on the display unit 110 of the mobile terminal 100 for an initial predetermined time, and then proceed to procedure 2. That is, after the mobile terminal 100 is aligned based on the markers 130 to 133 displayed in procedure 1, the markers 130 to 133 are not displayed. Instead, the server 220 can display the marker image of procedure 1 on the display unit 110 of the mobile terminal 100 for an initial predetermined time, and then perform procedures 1 and 2 in parallel. That is, the marker image may be displayed as an initial image, or may be continuously displayed together with the images 120A and 120B shown in FIG. 6.

[0039] The present invention is not limited to the above-described embodiment, and components can be added, omitted, or modified as appropriate.

[0040] For example, the lid body 40 is not limited to being provided separately from the box body 10 as shown in Fig. 1. The box body 10A shown in Fig. 13 may have a first lid body 42 that covers the top opening 15 and a second lid body 43 that covers the front opening 16, which are integral with the box body 10A. The first and second lid bodies 42, 43 are connected to the box body 10A by a cuttable perforation, for example, and are separated from the box body 10A when in use.

[0041] As shown in Fig. 14, the box 10A has the same height L3 as the lid 40 shown in Fig. 1, so that the transparent plate 30 having the length L2 (see Fig. 1) can be stored vertically inside the box 10A. Also, 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 10A instead of the three-dimensional object 20.
