Description

[Technical field]

[0001] The present invention relates to a product packaging box including a lower box body and an upper box body that is connected to the lower box body by a hinge so as to be able to open and close freely and that contains products when placed over the lower box body. [Background technology]

[0002] In close relationships, men often give jewelry to women as a gift. When a man and a woman purchase jewelry, the man visits a jewelry shop together with the woman. For example, as shown in Patent Document 1, the jewelry shop packs the jewelry in a specially prepared packaging box when delivering the jewelry. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-195405 A [Patent Document 2] Utility model registration No. 3050705 Summary of the Invention [Problem to be solved by the invention]

[0004] Scents leave a strong impression on people's memories. People can recall specific situations from scents. If a scent is linked to the scene of buying jewelry, a woman can vividly feel the joy of that moment every time she smells the scent. For example, if the scent inside a jewelry store is linked to a packaging box, a woman will surely remember the joy she felt when receiving a gift every time she approaches the packaging box at home. However, to date, there have been no packaging boxes used for packaging that incorporate a scent source. Therefore, scent memories have not been used as a trigger to recall the joy of receiving a gift.

[0005] In particular, jewelry brands also sell perfume. If the perfume wafts from the jewelry packaging, women will surely remember the joy they felt when they received the gift every time they put on the perfume. This will promote the use of perfume. Moreover, since the perfume in the packaging will dissipate over time, the perfume will be replenished to maintain the fragrance of the packaging. This will further promote the sales of perfume.

[0006] To provide a product packaging box that can create an opportunity to recall the joy felt when receiving a gift. [Means for solving the problem]

[0007] According to a first form of the present invention, there is provided a product packaging box comprising a lower box body, an upper box body connected to the lower box body by a hinge so as to be freely opened and closed, and defining a recess on its upper surface, a plate material which is fitted to the contour of the recess and fixed removably within the recess, and which defines a plane on its back surface for receiving pieces of paper containing aromatic components, a pair of rails which are connected to the back surface of the plate material and extend linearly in parallel on both sides of the plane, and a slider which is guided by the rails and displaces between a first position which holds the pieces of paper in line with the plane and a second position which moves away from the plane, wherein the recess defines a space which opens in a horizontal plane adjacent to the outer periphery of the plate material and includes the upper surface of the plate material, and the slider defines a passage which connects the space to a storage space for the pieces of paper which is in contact with the plane.

[0008] The fragrant components of the paper pieces leak from the passage into an adjacent space within the recess (hereinafter referred to as the "ventilation space"). The leaked fragrant components are dispersed from the ventilation space toward the upper part of the upper box body. In this way, the fragrance wafts around the product packaging box. The product packaging box can be used, for example, to pack gifts. The recipient of the gift can enjoy the fragrance every time they take out the product packaging box. Such a product packaging box can create an opportunity to recall the joy of receiving a gift. The impression of the giver can be strongly imprinted on the recipient. In addition, the product packaging box can be displayed indoors as a source of fragrance emission. The recipient of the gift can frequently see the product packaging box in the room. In this way, the recipient of the gift can frequently recall the joy of receiving a gift. The impression of the giver can be strongly imprinted on the recipient.

[0009] The plate can be removed from the recess. The piece of paper can be pulled away from the plate as a single piece by displacing the slider. Since the piece of paper is itself an absorbent for the fragrance, the fragrance only needs to soak into the piece of paper. For example, the fragrance can be simply sprayed onto the piece of paper, like perfume. The fragrance can be replenished in a short time and without hassle. Furthermore, the scent can be easily switched to another scent by simply replacing the piece of paper. A different fragrance, like perfume, can be simply sprayed onto a new piece of paper.

[0010] The product packaging box may further include a holder attached to the plate and holding an instant film following a receiving plane defined on the front or back surface of the plate. A scene of the product purchase can be developed on the instant film on the spot. The plate serves to hold the instant film within the recess. In this way, the instant film can be easily attached to the product packaging box. The viewer can enjoy the image on the instant film along with the scent. The image can further enhance the emotion of receiving the gift.

[0011] The plate material may be a resin plate that defines the flat surface and the receiving flat surface on the back surface and has a transparent area that covers at least the image on the instant film. An observer can observe the image on the instant film through the transparent area. The plate material can protect the image on the instant film while ensuring the visibility of the image. Here, the holder can be maintained on the plate material when the slider is removed. The instant film can continue to be held on the plate material as it is when the piece of paper is replaced. Misalignment of the instant film can be avoided when the piece of paper is replaced.

[0012] The plate may be made of a transparent material, and an opaque film may be formed on the surface of the plate to cover at least the edge of the instant film. The plate may be molded from a single transparent material. The plate may be molded in a simple process. Low-cost molding may be achieved. Meanwhile, since the edge of the instant film is hidden by the opaque film, the image may be well highlighted.

[0013] The holder may be a slider that is guided by a pair of rails extending parallel to both sides of the receiving plane and displaces between a first position where the instant film is held following the receiving plane and a second position where the instant film is released from the receiving plane. Since the rails are disposed on the back surface of the plate, the surface of the plate can be maintained as a smooth surface. The visibility of the image can be maintained well. The instant film can be removed from the plate in response to the displacement of the holder. Here, the holder can be formed with an outward surface that is flush with the rails. In this way, the shape of the back surface of the plate can be adjusted.

[0014] The passage may be a through hole formed in the slider with one end facing the piece of paper, a magnet may be fixed to the back surface of the plate, forming a gap between the horizontal surface in the recess and the slider that connects the through hole to the space, and a magnetic body may be fixed to the upper box body that receives the attractive force of the magnet on the horizontal surface. The plate body can be fixed in the recess of the upper box body by the action of the magnet. The plate body and the support plate can be well held in the recess regardless of whether the upper box body is opened or closed. The aroma components of the piece of paper flow out from the through hole to the horizontal surface and the gap between the slider and leak into the ventilation space. The leaked aroma components are dispersed from the ventilation space toward the upper box body.

[0015] According to a second form of the present invention, there is provided a product packaging box comprising a lower box body, an upper box body connected to the lower box body by a hinge so as to be freely opened and closed, and defining a recess on its upper surface, a plate material which is fitted to the contour of the recess and fixed removably within the recess, and which defines a plane on its back surface for receiving pieces of paper containing aromatic components, a pair of rails which are connected to the back surface of the plate material and extend linearly in parallel on both sides of the plane, and a slider which is guided by the rails and displaces between a first position which holds the pieces of paper in line with the plane, and a second position which separates from the plane, wherein the plate material is connected to a storage space for the pieces of paper which is in contact with the plane, and defines a through opening which opens on the surface of the plate material.

[0016] The aromatic components of the paper pieces can be diffused from the through holes toward the upper side of the board. The aroma wafts around the product packaging box. The product packaging box can be used, for example, to pack gifts. The recipient of the gift can enjoy the aroma every time they take out the product packaging box. Such a product packaging box can create an opportunity to recall the joy they felt when receiving the gift. The impression of the giver can be strongly imprinted on the recipient. In addition, the product packaging box can be displayed indoors as a source of aroma emission. The recipient of the gift can frequently see the product packaging box in the room. In this way, the recipient of the gift can frequently recall the joy they felt when receiving the gift. The impression of the giver can be strongly imprinted on the recipient.

[0017] The plate can be removed from the recess. The piece of paper can be pulled away from the plate as a single piece by displacing the slider. Since the piece of paper is itself an absorbent for the fragrance, the fragrance only needs to soak into the piece of paper. For example, the fragrance can be simply sprayed onto the piece of paper, like perfume. The fragrance can be replenished in a short time and without hassle. Furthermore, the scent can be easily switched to another scent by simply replacing the piece of paper. A different fragrance, like perfume, can be simply sprayed onto a new piece of paper. Effect of the Invention

[0018] As described above, according to the present invention, a product packaging box can be provided that can create an opportunity to recall the joy felt when receiving a gift. [Brief description of the drawings]

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0021] FIG. 1 is a schematic diagram of a product packaging unit according to an embodiment of the present invention. The product packaging unit 101 includes an outer box 102. The outer box 102 is formed of a lower outer box 103 and an upper outer box 104 that covers the lower outer box 103 from above. As shown in FIG. 2, the lower outer box 103 is composed of a bottom plate 103a having a rectangular outline and four side plates 103b that rise vertically from the four sides of the bottom plate 103a. A rectangular storage space is defined inside the lower outer box 103. An inner box (product packaging box) 11 is stored in the storage space. The bottom plate 103a and the side plates 103b are individually formed of flat paper boards. The bottom plate 103a and the side plates 103b, as well as the side plates 103b, are connected to each other by ridges. The lower outer box 103 has a seamless, continuous appearance by the ridges.

[0022] The upper outer box 104 is composed of a top plate 104a having a rectangular outline and four side plates 104b that descend vertically from the four sides of the top plate 104a. The top plate 104a is supported by the upper ends of the side plates 103b of the lower outer box 103 and closes the opening 105 of the lower outer box 103 that is surrounded by the side plates 103b. The side plates 104b of the upper outer box 104 surround the side plates 103b of the lower outer box 103. The top plate 104a and the side plates 104b are individually formed of flat paper boards. The top plate 104a and the side plates 104b, as well as the side plates 104b themselves, are connected to each other by ridges. For example, a logo of the distributor or manufacturer can be printed on the top surface of the upper outer box 104. The upper outer box 104 has a seamless, continuous appearance at the ridges. The upper outer box 104 is entirely opaque. Alternatively, the top plate 104a may be made of a transparent resin material.

[0023] As shown in Fig. 3, the inner box 11 includes a lower box body 12 and an upper box body 13 that overlaps the lower box body 12 to form a rectangular parallelepiped together with the lower box body 12. The lower box body 12 includes a hard resin molded body having a bottom plate 14a with a rectangular outline and four side walls 14b that rise vertically from the four sides of the bottom plate 14a, and a sticker 15 that is attached to the outer surface of the resin molded body to decorate the resin molded body. The upper box body 13 includes a hard resin molded body having a top plate 16a that receives a fragrance unit 62 in a recess 61 with a rectangular outline, and side walls 16b that descend from the four sides of the top plate 16a and join at their lower ends to the upper ends of the side walls 14b of the lower box body 12 to form the side walls of the inner box 11, and a sticker 17 that is attached to the outer surface of the resin molded body to decorate the resin molded body. The stickers 15 and 17 may be made of, for example, a suede-like or cloth-patterned resin sheet. Sticker 17 covers the inner surface of recess 61. The inner surface of recess 61 is neatly arranged with sticker 17. Upper box body 13 is formed of a material that blocks ventilation (non-breathable material) at least in the range that separates recess 61.

[0024] The fragrance unit 62 includes a plate 62a that is fitted to the contour of the recess 61 and fixed in the recess 61. The plate 62a is fitted into the recess 61. When fitted, the plate 62a comes into contact with the inner wall surface of the recess 61 at, for example, the upper and lower edges in a plan view. The upper and lower edges (or either one) in a plan view position the plate 62a in the up-down direction in a plan view. The plate 62a can be made of, for example, a transparent hard acrylic plate. The plate 62a is formed of a material that blocks ventilation (a non-breathable material). The surface of the plate 62a defines a flat surface 63. The space above the flat surface 63 is surrounded by an enclosure 64. The enclosure 64 has a wall surface 64a that rises from a horizontal plane including the flat surface 63 in accordance with the contour of the recess 61. The wall surface 64a is continuous with the inner wall surface of the recess 61 within one vertical plane for each side of the contour. The wall surface 64a can guide the downward movement of the plate material 62a in the vertical direction. Thus, the plate material 62a and the enclosure 64 cooperate to form a tray on the top surface of the upper box body 13. The plate material 62a constitutes the entire bottom plate of the tray. Here, the recess 61 defines a space 65 that is adjacent to the outer periphery of the plate material 62a and opens on a horizontal plane including the flat surface 63. The space 65 is located outside the left and right edges in a plan view. The space 65 may be located on either the left or right edge. The space 65 opens to a dimension that prevents small items from falling when used as a tray.

[0025] As shown in FIG. 4, the plate 62a covers the instant film 66 placed in the recess 61. The lower surface of the plate 62a is overlapped on the upper surface of the instant film 66. In a plan view, the entire instant film 66 is placed under the plate 62a. Here, an opaque film 67 that covers at least the edge of the instant film 66 is formed on the surface of the plate 62a. The opaque film 67 extends to the outer edge of the plate 62a all around, surrounding, for example, a window 68 that displays the image of the instant film 66. Therefore, the plate 62a forms a transparent area that covers at least the image of the instant film 66, corresponding to the window 68. The observer can observe the image of the instant film 66 from the transparent area. The opaque film 67 can be composed of, for example, a colored painted film.

[0026] 5, the plate member 62a defines, on the back surface thereof, a first plane (receiving plane) 71 for receiving the instant film 66 and a second plane (plane) 73 for receiving the piece of paper 72. The second plane 73 is disposed without overlapping the first plane 71. The second plane 73 is separated from the first plane 71.

[0027] The fragrance unit 62 is equipped with a first holder 74 that is attached to the plate material 62a and holds the instant film 66 along the first plane 71. The first holder 74 is a slider that is guided by a pair of first rails 76 that extend parallel to both sides of the first plane 71 and displaces between a first position where the instant film 66 is held along the first plane 71, and a second position where the first holder 74 is removed from the first plane 71. Therefore, the first holder 74 is detachably attached to the plate material 62a.

[0028] The first rail 76 extends linearly parallel to the wall surface 64a. A first smooth surface 77 is defined between the first rails 76 on the back surface of the plate material 62a. The first rail 76 defines a guideway in contact with the first smooth surface 77. When defining the guideway, the first rail 76 forms a restricting edge 76a that receives the first holder 74 between the first smooth surface 77. The restricting edge 76a allows the first holder 74 to move horizontally along the guideway while restricting the first holder 74 from leaving the first plane 71 in any manner other than horizontal movement. Here, the first plane 71 is defined by the inner surface of a recess 78 drilled in the first smooth surface 77. The recess 78 is closed by the first holder 74 that overlaps the first smooth surface 77 at the first position, and defines a photo room that contains the instant film 66 between the first holder 74 and the first plane 71. The contour of the recess 78 may be matched to the contour of the instant film 66 .

[0029] The first holder (slider) 74 is formed as a flat plate that blocks the entire guideway in the first position. The upper edge of the flat plate engages with the restricting edge 76a of the upper first rail 76. The lower edge of the flat plate engages with the restricting edge 76a of the lower first rail 76. The first holder (slider) 74 can be molded from, for example, a hard acrylic resin. The first holder 74 is formed from a material that blocks air (a non-breathable material).

[0030] The fragrance unit 62 is provided with a second holder 75 that is attached to the plate material 62a and holds the piece of paper 72 along the second plane 73. The second holder 75 is a slider that is guided by a pair of second rails 79 extending parallel to both sides of the second plane 73 and displaces between a first position where it holds the piece of paper 72 along the second plane 73, and a second position where it is removed from the second plane 73. Therefore, the second holder 75 is detachably attached to the plate material 62a.

[0031] The second rail 79 extends linearly parallel to the wall surface 64a. A second smooth surface 81 is defined between the second rails 79 on the back surface of the plate material 62a. The second rail 79 defines a guideway in contact with the second smooth surface 81. When defining the guideway, the second rail 79 forms a restricting edge 79a that receives the second holder 75 between the second rail 79 and the second smooth surface 81. The restricting edge 79a allows the second holder 75 to move horizontally along the guideway while restricting the second holder 75 from leaving the second plane 73 in any manner other than horizontal movement. Here, the second plane 73 is defined by the inner surface of a recess 82 drilled in the second smooth surface 81. The recess 82 is closed by the second holder 75 that overlaps the second smooth surface 81 in the first position, and defines a paper piece chamber that accommodates the paper piece 72 between the second holder 75 and the second plane 73.

[0032] The second holder (slider) 75 is formed as a flat plate that blocks the entire guideway in the first position. The upper edge of the flat plate engages with the restricting edge 79a of the upper second rail 79. The lower edge of the flat plate engages with the restricting edge 79a of the lower second rail 79. The second holder (slider) 75 can be molded from, for example, a hard acrylic resin. The second holder 75 is formed from a material that blocks air (a non-breathable material).

[0033] The piece of paper 72 contains an aroma component. The piece of paper 72 is formed in parallel to the wall surface 64a in a long length. The contour of the depression 82 may be set to match the contour of the piece of paper 72. The piece of paper 72 has an absorbency for retaining a solvent for the aroma component. The piece of paper 72 can be soaked in perfume, for example. The piece of paper 72 may be made of a paper material that changes color in response to the absorption of the aroma component. For example, litmus paper can change color in response to the pH, which changes in response to the absorption of the aroma component.

[0034] As shown in FIG. 6, a magnet 83 is fixed to the back surface of the plate material 62a at a position offset from the guideway defined by the first rail 76 and the second rail 79. When the fragrance unit 62 is received on a horizontal surface 84 in the recess 61, the magnet 83 comes into surface contact with the horizontal surface 84. Here, a magnetic body 85 is incorporated in the upper box body 13 to establish the horizontal surface 84. The magnetic body 85 is formed, for example, of a thin plate that forms the bottom surface of the recess 61. The thin plate may be, for example, a stainless steel plate. The magnetic body 85 is subjected to the attractive force of the magnet 83 on the horizontal surface 84. In this way, the magnetic force of the magnet 83 connects the fragrance unit 62 to the magnetic body 85. The magnet 83 protrudes at a determined height from one plane including the back surface of the plate material 62a. The magnet 83 forms a gap Hs between the second holder 75 and the horizontal surface 84. The gap Hs is connected to the space 65 at the outer periphery of the plate material 62a.

[0035] The second holder 75 defines a passage that connects the paper piece chamber to the space 65. To define the passage, the second holder 75 is formed with a through hole 86 that faces the paper piece 72 at one end and opens into the gap Hs between the second holder 75 and the horizontal surface 84 at the other end. The aroma components of the paper piece 72 can flow out from the through hole 86 into the gap Hs. The aroma components leak out from the gap Hs into the space 65. The aroma components are dissipated from the space 65 into the atmosphere.

[0036] Alternatively, as shown in FIG. 7, the first plane 71 and the second plane 73 may be formed flush with the rear surface of the plate material 62a. Here, the first plane 71 is included in the first smooth surface 77. A recess 78 is formed in the first holder 74 at a position overlapping the first plane 71. At the first position of the first holder 74, the first smooth surface 77 (first plane 71) closes the recess 78. In this way, a photo room for storing the instant film 66 is defined between the first holder 74 and the first plane 71. Similarly, the second plane 73 is included in the second smooth surface 81. A recess 82 is formed in the second holder 75 at a position overlapping the second plane 73. At the first position of the second holder 75, the second smooth surface 81 (second plane 73) closes the recess 82. In this way, a paper piece room for storing the paper piece 72 is defined between the second holder 75 and the second plane 73. Similarly, the second holder 75 has a through hole 86 that connects the paper piece chamber to the outside space. The aroma components of the paper piece 72 can be diffused to the outside space through the through hole 86. The distance Hs between the second holder 75 and the horizontal surface 84 connects the through hole 86 to the atmosphere.

[0037] As shown in Fig. 8, in the lower box body 12, a cushioning material 18 is fitted into a rectangular parallelepiped space surrounded by the side wall 14b. The cushioning material 18 is formed, for example, of a sponge and a cloth material 18a that encases the sponge. A slit 19 is formed in the cushioning material 18. For example, a ring (jewelry) 21 is inserted into the slit 19. The ring 21 is held in the slit 19 by the elastic force of the cushioning material 18.

[0038] The ring 21 includes a platinum ring member 22 having a diameter corresponding to the thickness of the finger, and a diamond grain 23 fixed to the base of the ring member 22. The diamond grain 23 may be one or more. The diamond grain 23 has strong or higher blue fluorescence (strong blue or very strong blue). The diamond grain 23 shines transparently under visible light (e.g., natural light or electric light), while shining blue under ultraviolet light. The diamond grain 23 is supported by the lower box body 12 in this manner. When multiple diamond grains 23 are arranged, it is preferable that the blue fluorescence of all the diamond grains 23 (or each group that is cohesive in design) is unified to strong blue or very strong blue.

[0039] A lining material 24 is fitted into the rectangular parallelepiped space surrounded by the side walls 16b of the upper box body 13. The lining material 24 comprises a decorative top plate 24a with a rectangular outline that forms the ceiling surface of the inner box 11, and four lining plates 24b that are continuous with each of the four sides of the decorative top plate 24a and are layered from the inside on the four side walls 16b. Here, the four lining plates 24b are not bonded to the inner surfaces of the side walls 16b, and the lining material 24 is housed in the upper box body 13 in a detachable manner.

[0040] As shown in Fig. 9, the upper box body 13 is connected to the lower box body 12 by a hinge 26 so as to be freely opened and closed. The hinge 26 includes a first blade 27 having a plurality of tubes 27a, which is stacked and fixed to one side wall 16b of the upper box body 13 from the inside, a second blade 28 having a plurality of tubes 28a arranged alternately in series on the tube 27a of the first blade 27, and one hinge pin 29 commonly inserted into the tube 27a of the first blade 27 and the tube 28a of the second blade 28. The first blade 27 and the second blade 28 rotate relatively around the hinge pin 29. The central axis of the hinge pin 29 corresponds to the rotation axis of the upper box body 13 when opening and closing.

[0041] A leaf spring 31 is connected to the hinge 26. As shown in FIG. 10, the leaf spring 31 is formed as a curved body that maintains a generatrix parallel to the axis of the hinge pin 29. Both ends of the leaf spring 31 are respectively connected to the first and second wings 27 and 28 at positions away from the hinge pin 29. In the closed position where the lower end of the upper box body 13 is aligned with the upper end of the lower box body 12, the first and second wings 27 and 28 are arranged side by side along one plane, and the middle region of the leaf spring 31 is furthest inward from the hinge pin 29. As the upper box body 13 is displaced around the hinge pin 29 from the closed position to the open position, the outer angle between the first and second wings 27 and 28 narrows, and the middle region of the leaf spring 31 approaches the hinge pin 29. As shown in Fig. 11, when the intermediate region of the leaf spring 31 contacts the hinge pin 29, the displacement of the upper box body 13 around the hinge pin 29 relative to the lower box body 12 is restricted, and the open position of the upper box body 13 is determined. When the opening angle around the hinge pin 29 is smaller than a specified intermediate opening angle, the leaf spring 31 applies a driving force to the upper box body 13 toward the closed position. When the opening angle is larger than the specified intermediate opening angle, the leaf spring 31 applies a driving force to the upper box body 13 toward the open position. The hinge 26 and the leaf spring 31 are covered with a hinge cover 32. The hinge cover 32 is formed, for example, from a material similar to the fabric material 18a of the cushioning material 18.

[0042] An LED lamp (light source) 33 that emits ultraviolet light in accordance with a predetermined directivity Dv is embedded in the decorative top plate 24a of the upper box body 13. The LED lamp 33 emits light rays, for example, long wavelength UV-A (optimally wavelength 395 nm to 405 nm). Desirably, the LED lamp 33 emits only light rays other than visible light. Desirably, the LED lamp 33 has a narrow directivity Dv. The LED lamp 33 has a directivity Dv that is blocked by the lower box body 12 over the entire irradiation area.

[0043] A battery 35 is connected to the LED lamp 33. The battery 35 is housed in a battery chamber 34 defined between the resin-molded top plate 16a and the decorative top plate 24a. The battery 35 may be, for example, a thin button battery. Here, for example, a plurality of button batteries are connected in series. A current is supplied to the LED lamp 33 from the battery 35.

[0044] A switch 36 that controls the supply and cut-off of current to the LED lamp 33 is incorporated in the hinge 26 and the leaf spring 31. A first contact 37 is fixed to the middle region of the leaf spring 31 while being electrically insulated from the leaf spring 31. The hinge 26 functions as a second contact that cooperates with the first contact 37 to configure the switch 36. Therefore, the hinge 26 is made of a conductive material. The first contact 37 is made of a conductive material such as copper. For example, an insulator is sandwiched between the first contact 37 and the leaf spring 31. The first contact 37 is disposed on a surface of the leaf spring 31 that faces the hinge pin 29. The first contact 37 comes into contact with the hinge 26 when the upper box body 13 is in the open position, and is separated from the hinge 26 when the upper box body 13 is in a position other than the open position.

[0045] As shown in FIG. 12, a light irradiation circuit 38 according to a first specific example including an LED lamp 33, a battery 35, and a switch 36 is constructed in the inner box 11. In the light irradiation circuit 38, the LED element of the LED lamp 33 is connected in series to the battery 35. A timer-limited normally open contact (hereinafter, "timer contact") 39 is connected in series to the LED lamp 33. A switch 36 and a timer 41 are connected in parallel to the LED lamp 33 and the timer contact 39. When the switch 36 is conductive, the timer 41 operates, and the timer contact 39 closes after a predetermined time (hereinafter, "first time") has elapsed. As a result, the LED lamp 33 is energized. When the switch 36 is opened, the timer 41 is restored and the timer contact 39 is opened. As a result, the LED lamp 33 is turned off.

[0046] 13, an audio playback unit 45 that plays back recorded audio is built into the inner box 11. The audio playback unit 45 includes an audio circuit 48 that receives an audio signal from a microphone 46 and supplies the audio signal to a speaker 47. The audio circuit 48 is connected to the battery 35. The audio circuit 48 operates by receiving the voltage from the battery 35.

[0047] The microphone 46 detects vibrations in the air based on sound and converts them into an audio signal (electrical signal). The generated audio signal is recorded, for example, in a memory 49. For example, an EEPROM can be used for the memory 49. The memory 49 is preferably a memory that allows an audio signal to be written only once. The microphone 46 is supported by the upper box 13 or the lower box 12. Here, for example, the microphone 46 is housed in a space partitioned between the top plate 16a and the decorative top plate 24a. The top plate 16a or the decorative top plate 24a may have a through hole formed therein, which is disposed in correspondence with the position of the microphone 46 and connects outside air to the microphone 46.

[0048] The speaker 47 generates vibrations in the air based on an audio signal and reproduces the corresponding sound. The reproduced sound stimulates the observer's hearing. In this way, the observer can hear the sound. The speaker 47 is supported by the upper box body 13 or the lower box body 12. Here, the speaker 47 is housed in a space partitioned between the tabletop 16a and the decorative tabletop 24a, for example. The tabletop 16a or the decorative tabletop 24a may have a through hole disposed in correspondence with the position of the speaker 47 and connecting the outside air to the speaker 47.

[0049] A hold circuit 51 is connected to the audio playback unit 45, which holds audio playback until a predetermined time (hereinafter referred to as the "second time") has elapsed since the start of ultraviolet irradiation. The hold circuit 51 connects the switch 36 to the audio circuit 48. The battery 35 and switch 36 are common to the audio circuit 48 and the light irradiation circuit 38. The hold circuit 51 measures (first time + second time) from the time the switch 36 becomes conductive. Here, when the predetermined second time has elapsed since the start of ultraviolet irradiation, the audio circuit 48 retrieves an audio signal from the memory 49 and supplies it to the speaker 47.

[0050] A recording switch 52 is connected to the audio circuit 48. When the recording switch 52 is conductive, the audio circuit 48 acquires an audio signal from the microphone 46 and stores the audio signal in the memory 49. As shown in FIG. 14, the button of the recording switch 52 can be installed on the inner wall surface of the upper box 13. Here, the recording switch 52 is conductive as long as the button is kept pressed. When the button is released from the pressing operation, the recording switch 52 is disconnected. By arranging the button inside the upper box 13, the recording switch 52 can be protected from erroneous operation simply by the upper box 13 being in the closed position. The upper box 13 functions as a protective body that protects the recording switch 52 from objects other than the components of the inner box 11. In this way, unintentional recording of audio (deletion of audio based on overwriting) can be prevented. In addition, the recording switch 52 may be linked to the conduction of the switch 36. As a result, when the recording switch 52 is operated with the upper box 13 reaching the open position, audio can be recorded in the memory 49.

[0051] The LED lamp 33, timer contact 39, timer 41, audio circuit 48, memory 49 and hold circuit 51 may be mounted on a common printed circuit board, for example. The first contact 37 of switch 36, the first blade 27 or second blade 28 of hinge 26, battery 35, microphone 46, speaker 47, etc. may be electrically connected to a wiring pattern on the printed circuit board by electric wires such as vinyl-coated wires. The printed circuit board may be housed in the battery chamber 34, for example.

[0052] Next, the function of the inner box 11 will be described. As shown in Fig. 3, when the upper box body 13 is located in the closed position, the lower edge of the upper box body 13 is aligned with the upper edge of the lower box body 12. The upper box body 13 covers the ring 21 and hides the diamond grains 23. An observer of the inner box 11 visually recognizes the outer appearance of the closed inner box 11. The diamond grains 23 are out of the view of the observer.

[0053] At this time, as shown in Fig. 10, the intermediate region of the leaf spring 31 is farthest from the hinge pin 29. Therefore, the first contact 37 of the switch 36 is separated from the hinge 26, i.e., the second contact. The switch 36 is disconnected. The LED lamp 33 is maintained in an unlit state. The operation of the audio circuit 48 is maintained in a stopped state.

[0054] When an observer moves the upper box body 13 around the hinge pin 29 toward the open position against the elastic force of the leaf spring 31, the lower end of the upper box body 13 moves away from the upper end of the lower box body 12. Visible light penetrates through the gap between the upper box body 13 and the lower box body 12 toward the diamond grains 23. The diamond grains 23 are gradually exposed. The diamond grains 23 are exposed to irradiation with visible light. Therefore, the diamond grains 23 emit a transparent shine.

[0055] When the opening angle of the upper box body 13 increases beyond the specified intermediate opening angle, the leaf spring 31 drives the upper box body 13 toward the open position. As a result, the upper box body 13 reaches the maximum opening position. The upper box body 13 is held in the maximum opening position according to the elastic force of the leaf spring 31. The flat surface 63 of the upper box body 13 is positioned higher as it moves away from the axis of rotation. As shown in FIG. 8, the observer can see the diamond grains 23 without being obstructed by the upper box body 13. The diamond grains 23 emit a transparent glow under visible light (natural light or electric light).

[0056] When the upper box body 13 reaches the open position, as shown in Fig. 11, the elastic force of the leaf spring 31 presses the middle region of the leaf spring 31 against the hinge pin 29. Thus, the first contact 37 comes into contact with the hinge 26, i.e., the second contact. The switch 36 becomes conductive. When the first time has elapsed since the switch 36 became conductive (ON operation), the LED lamp 33 turns on. The LED lamp 33 starts irradiating the diamond grains 23 with ultraviolet light. The diamond grains 23 glow blue.

[0057] After the diamond grains 23 are observed shining transparently for a while after the upper box body 13 is opened, the diamond grains 23 change color from transparent to blue. In this way, a light dramatic effect is created in response to the opening action of the upper box body 13. Since the leaf spring 31 exerts a driving force to position the upper box body 13 at the open position, the diamond grains 23 are prevented from starting to change color at a position intermediate between the closed position and the open position, and the observer can reliably witness the change in color of the diamond grains 23.

[0058] When the second time has elapsed since the start of the ultraviolet irradiation, the audio circuit 48 reproduces the recorded audio. For example, if it is a present, the giver's voice (for example, "Marry me" or "Let's be together from now on") can be delivered to the observer. Since the reproduction of the audio is delayed from the visual effect of the diamond grains 23, the visual effect of the diamond grains 23 and the audio production effect act on the observer in sequence. The observer can become aware of the auditory effect of the audio (including language processing) after becoming aware of the visual effect of the diamond grains 23. The audio production effect is added to the visual effect. According to the inventor's realization, since humans cannot be aware of multiple senses at the same time, the synergistic effect of the visual and audio can be strengthened by delaying the reproduction of the audio from the visual effect, compared to when the audio production effect progresses simultaneously with the visual effect. With this production effect, the observer of the inner box 11 can experience an emotion that cannot be experienced anywhere else.

[0059] When the switch 36 is disconnected, the LED lamp 33 goes out. The audio circuit 48 stops supplying the audio signal. The audio playback ends.

[0060] Prior to giving the gift, the giver's voice is recorded in the inner box 11. To record, the upper box body 13 is positioned in the open position. The giver presses the recording switch 52 and speaks into the microphone 46 (for example, "Will you marry me?" or "Let's be together from now on"). The audio circuit 48 operates in response to the conduction of the recording switch 52. The voice is converted into an audio signal by the microphone 46. The audio signal is stored in the memory 49. When the finger is released from the button of the recording switch 52, the voice recording ends.

[0061] Here, it is preferable that the fabric material 18a of the cushioning material 18 is colored in a color such as black or dark blue. With such coloring, even if the light from the LED lamp 33 slightly contains visible light adjacent to the ultraviolet range, the visible light shining on the fabric material 18a is not noticeable. The light from the LED lamp 33 can be excluded from the viewer's vision.

[0062] For example, consider a scene in which a man and a woman visit a jewelry shop to purchase jewelry. The interior of the jewelry shop is filled with a scent specific to the jewelry shop and the brand. Fragrance components that give the impression of the scent of the store permeate the pieces of paper 72 in the inner box 11. In this way, the scent of the interior of the jewelry shop becomes associated with the inner box 11. When the ring 21 is purchased at the jewelry shop, the scene of the purchase can be linked to the scent. The scent is strongly remembered by the man and the woman.

[0063] When the inner box 11 is taken out of the outer box 102, the fragrance of the jewelry shop wafts around the inner box 11. As shown in FIG. 15, the fragrance components of the paper piece 72 flow out from the through hole 86 into the gap Hs between the second holder 75 and the horizontal surface 84, and leak out from the gap Hs into the space 65. The leaked fragrance components are diffused from the space 65 toward the upper part of the upper box body 13. The woman can enjoy the fragrance every time she takes out the inner box 11. If the woman received the ring 21 as a gift, she will remember the joy of receiving the gift every time she approaches the inner box 11 at home. The inner box 11 can create an opportunity to remember the joy of receiving a gift. The man's impression can be strongly planted on the woman.

[0064] The inner box 11 can be displayed in the room as a source of fragrance emission. The woman can see the inner box 11 frequently in the room. In this way, the woman can frequently remember the joy she felt when she received the gift. The impression of the man can be strongly imprinted on the woman.

[0065] The enclosure 64 functions to form a tray on the top surface of the upper box 13. Small items such as the ring 21 and key chains can be placed on the plate material 62a. The enclosure 64 functions to hold the small items on the plate material 62a. Since such a tray is used daily, the woman can see the inner box 11 frequently. The emotions felt when receiving the gift can be strongly imprinted in the woman's memory. The impression of the ring 21, the brand, and the jewelry store at the time of purchase can be strongly imprinted on the observer of the inner box 11.

[0066] The plate 62a is fixed to the magnetic body 85 by the magnetic force of the magnet 83. Access to the outer periphery of the plate 62a can be permitted from the space 65. The plate 62a can be easily pulled up from the recess 61 by applying an external force to the outer periphery of the plate 62a. The fragrance unit 62 can be easily removed from the upper box 13. As described above, the piece of paper 72 can be taken out of the fragrance unit 62, so that the piece of paper 72 can be replenished with the fragrance component. Alternatively, the piece of paper 72 may be replaced with one that contains a sufficient amount of the fragrance component. In this way, the woman can enjoy the fragrance from the inner box 11 forever. The space 65 can be formed to be thin and extend along the left and right edges of the plate 62a, and can be formed to be large enough to receive, for example, the insertion of a ring 21. In this case, a hard tool can be inserted into the space 65 to remove the fragrance unit 62. The space 65 may be formed to be large enough for the fingertip to reach the horizontal surface 84.

[0067] For example, in a jewelry shop, the scene of the purchase can be captured by an instant camera. The scene of the purchase can be developed on the spot onto an instant film 66. The plate 62a serves to hold the instant film 66 within the recess 61. In this way, the photograph can be easily attached to the inner box 11. An observer can enjoy the image on the instant film 66 through the transparent plate 62a. The image can further enhance the emotion of receiving the gift.

[0068] The inner box 11 according to this embodiment causes the diamond grains 23 to change color from transparent to fluorescent blue. The owner of the ring 21 uses the inner box 11 to enjoy the color change of the diamond grains 23. In this way, the inner box 11 continues to be owned together with the ring 21. The opportunities for the inner box 11 to be taken out increase. The opportunities for seeing images on the instant film 66 increase. With general products, the packaging box is often thrown away once the product begins to be used.

[0069] Similarly, the inner box 11 according to this embodiment plays back recorded sound. Since the sound production effect is realized in this way, the owner of the ring 21 keeps the inner box 11 instead of throwing it away, and enjoys the sound production effect. In this way, the inner box 11 continues to be owned together with the ring 21. The opportunities for the inner box 11 to be taken out further increase. The opportunities for viewing the images on the instant film 66 further increase.

[0070] As shown in FIG. 16, when the fragrance unit 62 is assembled, the plate material 62a may be formed with a through hole 87 that extends from the paper piece chamber and opens to the surface of the plate material 62a. The lower end of the through hole 87 overlaps the piece of paper 72 inside the contour of the piece of paper 72. The fragrant components of the piece of paper 72 can be diffused from the through hole 87 toward the upper part of the plate material 62a. The fragrance wafts around the inner box 11. Here, the magnet 83 can be embedded in the back surface of the plate material 62a. The back surface of the plate material 62a can be trimmed to be flush.

[0071] As shown in FIG. 17, the fragrance unit 62 may include a plate 62b, instead of the plate 62a described above, which is fitted to the contour of the recess 61 and fixed within the recess 61. The plate 62b defines a first plane (receiving surface) 89 for receiving the instant film 66 on the front side, and defines a second plane (flat surface) 91 for receiving the piece of paper 72 on the back side. The second plane 91 is disposed without overlapping the first plane 89. The second plane 91 is separated from the first plane 89. The plate 62b may be composed of, for example, a transparent body as a whole. The transparent body may be molded from, for example, a hard acrylic resin. Alternatively, the plate 62b may be formed from an opaque material. The plate 62b is formed from a material that blocks ventilation (non-breathable material).

[0072] The fragrance unit 62 includes a first holder 92 attached to the plate 62b and holding the instant film 66 following the first plane 89, and a second holder 93 attached to the plate 62b and holding the piece of paper 72 following the second plane 91. The first holder 92 is placed on the surface of the plate 62b and holds the instant film 66 between the plate 62b. The first holder 92 can be made of a transparent body as a whole, for example. The transparent body can be molded from a hard acrylic resin, for example. The observer can view the image on the instant film 66 through the first holder 92. The second holder 93 is a slider that is guided by a pair of second rails 79 extending parallel to both sides of the second plane 91 and displaces between a first position where the piece of paper 72 is held following the second plane 91, and a second position where the second holder 93 is removed from the second plane 91, in the same manner as the second holder 75 described above. The second holding body 93 is formed from a material that blocks airflow (air-impermeable material).

[0073] When attaching the first holder 92, a magnetic body (not shown) is fixed to the surface of the plate material 62b at a position offset from the first plane 89 (instant film 66). A magnet (not shown) that exerts a magnetic force acting on the magnetic body is fixed to the back surface of the first holder 92. The magnet is embedded in the back surface of the first holder 92. When the first holder 92 is received on the surface of the plate material 62b, the magnetic body comes into surface contact with the magnet. The magnetic body only needs to have an outline that overlaps with the magnet when the first holder 92 is placed on the plate material 62b. The first holder 92 is detachably fixed to the plate material 62b by the action of the magnetic force. The instant film 66 is sandwiched between the plate material 62b and the first holder 92 that are placed on top of each other. The magnetic body and the magnet may be made of a transparent material. The magnetic body may be embedded in the surface of the plate material 62b.

[0074] Here, the piece of paper 72 is placed inside the outline of the instant film 66 projected onto the rear surface of the plate material 62b in a direction perpendicular to the front surface of the plate material 62b. Since the piece of paper 72 is placed behind the instant film 66, the piece of paper 72 can be hidden by the instant film 66 from the front side. The image of the instant film 66 can be well highlighted. Here, the outline of the first holder 92 is superimposed on the outline of the plate material 62b. Therefore, the first holder 92 and the plate material 62b can be recognized as one rectangular parallelepiped.

[0075] FIG. 18 shows a schematic configuration of a light irradiation circuit according to a second specific example. The light irradiation circuit 43 includes an NPN transistor TR1 connected to a battery 35. The LED element of the LED lamp 33 is connected between the positive terminal of the battery 35 and the collector C of the NPN transistor TR1. A switch 36 and a first resistor R1 are connected in series between the positive terminal of the battery 35 and the base B of the NPN transistor TR1. A capacitor C1 is connected between the base B of the NPN transistor TR1 and the negative terminal of the battery 35. A second resistor R2 is connected in parallel with the first resistor R1 and the capacitor C1. The emitter E of the NPN transistor TR1 is connected to the negative terminal of the battery 35. In this light irradiation circuit 43, when the switch 36 is turned on, the voltage applied to the base B of the NPN transistor TR1 gradually rises due to the action of the time constant circuits R1 and C1. When the voltage at the base B of the NPN transistor TR1 reaches a specified value during the voltage rise, a current flows into the collector C. After that, when a specified time has elapsed, the voltage applied to the base B of the NPN transistor TR1 is maintained constant. When the switch 36 is turned off, the charge in the capacitor C1 is discharged through the second resistor R2.

[0076] The hold circuit 51 of the sound reproduction unit 45 holds the sound reproduction until a predetermined time (hereinafter referred to as "third time") has elapsed after the ultraviolet light reaches the maximum light intensity. The battery 35 and the switch 36 are shared between the sound circuit 48 and the light irradiation circuit 43. The hold circuit 51 measures the time from when the switch 36 is turned on until the ultraviolet light reaches the maximum light intensity (hereinafter referred to as "gradual increase time"), and the third time. The gradual increase time can be specified by the voltage characteristics of the light irradiation circuit 43. The gradual increase time corresponds to the time from when the switch 36 is turned on until the voltage applied to the base B of the NPN transistor TR1 starts to be maintained at the maximum value. Here, when the predetermined third time has elapsed from the time when the ultraviolet light reaches the maximum light intensity, the sound circuit 48 retrieves the sound signal from the memory 49 and supplies it to the speaker 47.

[0077] The LED lamp 33, the NPN transistor TR1, the capacitor C1, the first and second resistors R1, R2, the audio circuit 48, the memory 49, and the hold circuit 51 may be mounted on a common printed circuit board, for example. The first contact 37 of the switch 36, the first blade 27 or the second blade 28 of the hinge 26, the battery 35, the microphone 46, the speaker 47, etc. may be electrically connected to a wiring pattern on the printed circuit board by electric wires such as vinyl-coated wires. The printed circuit board may be housed in the battery chamber 34, for example.

[0078] In the light irradiation circuit 43 according to the second specific example, after the upper box body 13 reaches the open position and the switch 36 is turned on, a specified voltage is applied from the battery 35 to the base B of the NPN transistor TR1 after a first time has elapsed since the switch 36 was turned on (ON operation). Current flows into the collector C of the NPN transistor TR1, and the LED lamp 33 starts to light up. Therefore, an observer of the inner box 11 can observe the diamond grains 23 that shine transparently for a while after the upper box body 13 is opened.

[0079] The voltage applied to the base B of the NPN transistor TR1 gradually rises due to the action of the time constant circuits R1 and C1. The amount of current flowing through the LED lamp 33 gradually increases. The amount of ultraviolet light irradiated from the LED lamp 33 to the diamond grains 23 increases. The diamond grains 23 gradually change color from transparent to blue. In this way, a light dramatic effect is created in response to the opening operation of the upper box body 13. The leaf spring 31 exerts a driving force to position the upper box body 13 in the open position, preventing the diamond grains 23 from starting to change color at a position intermediate between the closed position and the open position, and the observer can reliably witness the color change of the diamond grains 23.

[0080] When the second time has elapsed since the start of the irradiation of ultraviolet light, that is, when the third time has elapsed since the diamond grains 23 began to shine blue to the maximum, the audio circuit 48 plays back the recorded audio. For example, if it is a present, the giver's voice (for example, "Marry me" or "Let's be together from now on") can be delivered to the observer. Since the playback of the audio is delayed from the visual effect of the diamond grains 23, the visual effect of the diamond grains 23 and the audio production effect act on the observer in sequence. The observer can become aware of the auditory effect of the audio (including language processing) after becoming aware of the visual effect of the diamond grains 23. The audio production effect is added to the visual effect. According to the inventor's realization, since humans cannot be aware of multiple senses at the same time, the synergistic effect of the visual and audio can be strengthened by delaying the playback of the audio from the visual effect, compared to when the audio production effect progresses simultaneously with the visual effect. With this production effect, the observer of the inner box 11 can experience an emotion that cannot be experienced anywhere else.

[0081] When the switch 36 is disconnected, the LED lamp 33 goes out. The audio circuit 48 stops supplying the audio signal. The audio playback ends. The charge on the capacitor C1 is discharged through the second resistor R2.

[0082] The LED lamp 33 may be supported by the lower box 12 instead of the upper box 13. Alternatively, the diamond grains 23 may be mounted on a plurality of pedestals forming a necklace chain. The pedestals are formed from a metal material such as platinum or gold. One diamond grain 23 or a plurality of diamond grains 23 may be fixed to each pedestal. Alternatively, the diamond grains 23 may be arranged on a pendant, bracelet, earrings, ring, or anklet. The diamond grains may be of uniform size or may be mixed in size.

[0083] In the inner box 11 described above, the switch 36 may be a tactile switch having a plunger that is pushed down by the upper box body 13 when the upper box body 13 reaches the open position. The light irradiation circuit 38 according to the first specific example and the light irradiation circuit 43 according to the second specific example may be replaced with electronic circuits of other configurations as long as they realize the same functions as those described above. Furthermore, the operation of the switch 36 may not only be linked to the upper box body 13 being in the open position as described above, but may also be linked to the upper box body 13 being in the closed position. In addition, the functions of the light irradiation circuits 38 and 43, the sound circuit 48, and the hold circuit 51 may be realized by software executed by a microprocessor (MPU).
