Scents leave a strong impression on people's memories. People can recall specific situations from a scent. If a scent is linked to the scene of purchasing jewelry, the woman will be able to 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 the packaging box, the woman will surely remember the joy she felt when receiving the 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 source of scent emission. Therefore, the memory of a scent has not been used as a trigger to recall the joy of receiving a gift.

In particular, jewelry brands also sell perfume. If the perfume wafts from the jewelry packaging, women will surely be reminded of the joy they felt when receiving 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.

The present invention aims to provide a product packaging box that can remind people of the joy they felt when receiving a gift.

According to a first aspect of the present invention, a product packaging box is provided that includes a lower box body, an upper box body that is connected to the lower box body by a hinge so as to be freely opened and closed and defines a recess on its upper surface, and a plate material that is fixed within the recess to fit the contour of the recess and that is layered on a horizontal surface within the recess and covers a piece of paper containing an aroma component, the recess being adjacent to the outer periphery of the plate material and defining a space that opens on a horizontal surface including the upper surface of the plate material.

Due to the thickness of the paper piece, a small gap is formed between the board and the horizontal surface. Therefore, the fragrant components of the paper piece leak out from the outer periphery of the board into the adjacent space within the recess (hereinafter referred to as the "ventilation space"). The leaked fragrant components are dissipated from the ventilation space toward the top of the upper box body. In this way, the scent drifts 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 scent every time they take out the product packaging box. Such a product packaging box can create an opportunity to remember the joy of receiving a gift. The recipient can be strongly impressed by the giver.

In addition, the product packaging can be displayed in the room as a source of fragrance. The gift recipient can see the product packaging frequently in the room. In this way, the gift recipient can frequently recall the joy they felt when receiving the gift. The impression of the giver can be strongly imprinted on the recipient.

The product packaging box may include an enclosure having walls that rise from a horizontal plane including the surface of the plate material in accordance with the contour of the recess and surround the space on the surface of the plate material. The enclosure can form a tray on the top surface of the upper box body. Small items such as jewelry can be placed on the plate material. The enclosure can hold the small items on the plate material. Since such a tray is used daily, the owner of the product can see the product packaging box frequently. The emotions felt when receiving a gift can be strongly imprinted in the owner's memory. The product can be strongly imprinted on observers of the product packaging box.

The product packaging box may further include a support plate that is arranged in the recess so as to match the contour of the plate, defines the horizontal plane, receives the piece of paper on the horizontal plane, and is joined to the plate. In this case, the space may continue to a position adjacent to the support plate. The piece of paper containing the aroma component is sandwiched between the plate and the support plate. The plate, the piece of paper, and the support plate can function as one unit. Access to the periphery of the plate and the support plate can be permitted from the partitioned space. The plate and the support plate can be easily pulled up from the recess by applying an external force to the periphery of the plate and the support plate. The plate, the piece of paper, and the support plate can be easily removed as a set from the upper box body.

The product packaging box may include a magnet fixed to the plate material, and a magnetic body fixed to the support plate and attached to the magnet based on the magnetic force of the magnet, thereby fixing the support plate to the plate material. The lower plate material is fixed to the upper plate material by the action of magnetic force. A piece of paper containing an aromatic component is sandwiched between the plate material and the support plate. The support plate can be separated from the plate material against the magnetic force, so that the piece of paper can be replenished with the aromatic component. Alternatively, the piece of paper may be replaced. In this way, the recipient of the gift can continue to enjoy the aroma from the product packaging box. The magnet and magnetic body may be interchanged between the plate material and the support plate.

The product packaging box may further include a fixing magnetic body that is fixed to the upper box body and disposed below the magnetic body. The magnetic field lines of the magnet can flow through the magnetic body and the fixing magnetic body. Therefore, the support plate can be fixed in the recess by the action of the magnetic force. The plate material and the support plate can be well held in the recess regardless of whether the upper box body is open or closed.

At least the plate may be made of a transparent material. In this case, the plate may be covered with an instant film that is placed on the horizontal surface at a position horizontally offset from the piece of paper. A scene of the purchase of the product 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 photograph can be easily attached to the product packaging box. An observer can enjoy the image on the instant film by looking through the transparent plate. The image can serve to further enhance the emotion of receiving the gift.

According to a second aspect of the present invention, a product packaging box is provided that includes a lower box body, an upper box body that is connected to the lower box body by a hinge so as to be freely opened and closed and defines a recess on its upper surface, and a plate material that is fixed within the recess by fitting to the contour of the recess and that covers a piece of paper that is stacked on a horizontal surface within the recess and contains an aroma component, the plate material overlapping the piece of paper inside the contour of the piece of paper and having a through opening that opens on the upper surface of the plate material.

The fragrant components of the paper pieces can be diffused from the through holes toward the top of the board. 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 remember the joy they felt when 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 inside the room. In this way, the recipient of the gift can frequently remember the joy they felt when receiving a gift. The impression of the giver can be strongly imprinted on the recipient.

The piece of paper is sandwiched between the board and a horizontal surface. Because the opening of the board overlaps with the piece of paper inside the outline of the piece of paper, the board can press the piece of paper against the horizontal surface over the entire outline of the opening. This prevents the piece of paper from rippling inside the opening. The flat piece of paper can give the horizontal surface an aesthetic look. Because the piece of paper covers the opening without any gaps, the aromatic components of the piece of paper can efficiently drift upward from the opening. If gaps are created, the aromatic components will leak out of the gap and into places other than the opening.

The plate may be formed with a protrusion that protrudes from the bottom surface of the plate and bites into the piece of paper on the horizontal surface. When the plate presses the piece of paper against the horizontal surface, the pressure of the pressure can be concentrated on the protrusion. As a result, the protrusion can bite into the piece of paper. The piece of paper can be sandwiched between the plate and the horizontal surface with strong pressure. The piece of paper can be prevented from moving in the horizontal direction. The piece of paper can be held securely.

As described above, the present invention provides a product packaging box that can evoke the joy of receiving a gift.

One embodiment of the present invention will be described below with reference to the attached drawings.

Figure 1 shows a schematic diagram of a product packaging unit according to one 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 Figure 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 board. 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.

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 end of the side plate 103b of the lower outer box 103 and covers the opening 105 of the lower outer box 103 that is surrounded by the side plate 103b. The side plate 104b of the upper outer box 104 surrounds the side plate 103b of the lower outer box 103. The top plate 104a and the side plate 104b are individually formed of flat paper board. The top plate 104a and the side plate 104b, as well as the side plates 104b themselves, are connected to each other by ridges. For example, the logo of the seller 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 opaque overall. Additionally, a transparent resin material may be used for the top plate 104a.

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 top plate 16a that receives the fragrance unit 62 in a recess 61 with a rectangular outline, and a hard resin molded body having 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 resin sheet with a suede or cloth pattern. The sticker 17 covers the inner surface of the recess 61. The inner surface of the recess 61 is neatly arranged with the sticker 17.

The fragrance unit 62 includes an upper plate 62a that is fitted to the contour of the recess 61 and fixed in the recess 61. The upper plate 62a is fitted into the recess 61. When fitting, the upper plate 62a contacts 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 upper plate 62a in the up-down direction in a plan view. The upper plate 62a can be made of, for example, a transparent hard acrylic plate. The surface of the upper 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 descent of the upper plate 62a in the vertical direction. In this way, the upper plate material 62a and the enclosure 64 cooperate to form a tray on the top surface of the upper box body 13. The upper 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 upper plate material 62a and opens in 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 size that is sufficient to prevent small items from falling when used as a tray.

As shown in FIG. 4, the upper plate 62a covers the instant film 66 placed in the recess 61. The lower surface of the upper plate 62a is superimposed on the upper surface of the instant film 66. In plan view, the entire instant film 66 is placed below the upper plate 62a. A first decorative body 67a is fixed to the upper plate 62a at a position above the instant film 66 in plan view. The first decorative body 67a is printed on the flat surface 63 in a strip shape parallel to the upper edge in plan view. For example, opaque ink is used for the first decorative body 67a. Similarly, a second decorative body 67b is fixed to the upper plate 62a at a position below the instant film 66 in plan view. The second decorative body 67b is printed on the flat surface 63 in a strip shape parallel to the lower edge in plan view. For example, opaque ink is used for the second decorative body 67b.

As shown in FIG. 5, the cushioning material 18 is fitted into the rectangular space surrounded by the side wall 14b of the lower box body 12. The cushioning material 18 is formed, for example, from 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.

The ring 21 comprises a platinum ring member 22 having a diameter corresponding to the thickness of the finger, for example, and a diamond grain 23 fixed to the base of the ring member 22. There may be one or more diamond grains 23. 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 (for example, 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 way. When multiple diamond grains 23 are arranged, it is preferable that the blue fluorescence of all the diamond grains 23 (or a group of diamond grains that are cohesive in terms of design) is unified to strong blue or very strong blue.

The lining material 24 is fitted into the rectangular 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 onto the four side walls 16b. Here, the four lining plates 24b are not bonded to the inner surface of the side walls 16b, and the lining material 24 is stored in the upper box body 13 so that it can be freely attached and detached.

As shown in FIG. 6, the upper box body 13 is connected to the lower box body 12 by a hinge 26 so that it can be opened and closed freely. The hinge 26 includes a first blade 27 having a plurality of tubes 27a, which is stacked and fixed from the inside to one side wall 16b of the upper box body 13, a second blade 28 having a plurality of tubes 28a arranged alternately in series on the tube 27a of the first blade 27, which is stacked and fixed from the inside to the side wall 14b of the lower box body 12, and a single 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.

A leaf spring 31 is connected to the hinge 26. As shown in FIG. 7, the leaf spring 31 is formed into 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 blades 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 blades 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 from the closed position to the open position around the hinge pin 29, the outer angle between the first and second blades 27 and 28 narrows, and the middle region of the leaf spring 31 approaches the hinge pin 29. As shown in FIG. 8, 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 the 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.

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 wavelengths of 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.

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, multiple button batteries are connected in series. Current is supplied to the LED lamp 33 from the battery 35.

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 form the switch 36. Therefore, the hinge 26 is formed from a conductive material. The first contact 37 is formed from 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 the 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.

As shown in FIG. 7, the fragrance unit 62 includes a lower plate 62b that is stacked on the lower surface of the upper plate 62a from below and joined to the upper plate 62a. The lower plate 62b receives the lower surface of the instant film 66 on a horizontal surface 68 and holds the instant film 66 between the upper plate 62a and the lower plate 62b. The instant film 66 is sandwiched between the upper plate 62a and the lower plate 62b. The lower plate 62b may be made of a transparent material like the upper plate 62a, or may be made of an opaque material. The lower plate 62b has an outline that overlaps the outline of the upper plate 62a.

The fragrance unit 62 includes a first piece of paper 69a and a second piece of paper 69b that are received by the lower plate 62b on the horizontal surface 68. The first piece of paper 69a and the second piece of paper 69b are sandwiched between the upper plate 62a and the lower plate 62b. The first piece of paper 69a and the second piece of paper 69b are permeated with perfume. The first piece of paper 69a is disposed at a position above the instant film 66 in a plan view. The first piece of paper 69a extends, for example, in a strip parallel to the upper edge in a plan view. The first decorative body 67a is covered by the first piece of paper 69a in a plan view. The first piece of paper 69a is hidden by the first decorative body 67a. The second piece of paper 69b is disposed at a position below the instant film 66 in a plan view. The second piece of paper 69b extends, for example, in a strip parallel to the lower edge in a plan view. In plan view, the second decorative body 67b covers the second piece of paper 69b. The second piece of paper 69b is hidden by the second decorative body 67b.

As shown in FIG. 9, a small gap 71 is formed between the upper plate 62a and the lower plate 62b due to the thickness of the first and second pieces of paper 69a and 69b and the instant film 66. The gap 71 is connected to a space 65. The space 65 continues to a position adjacent to the lower plate 62b. In other words, the space 65 opens at a horizontal plane that is adjacent to the outer periphery of the upper plate 62a and the outer periphery of the lower plate 62b and includes the flat surface 63. The fragrant components of the first and second pieces of paper 69a and 69b can be released from the space 65 toward the upper plate 62a.

As shown in FIG. 10, a magnet 73 is fixed to the upper plate material 62a. The magnet 73 is embedded, for example, in the lower surface of the upper plate material 62a. In a plan view, the first decorative body 67a and the second decorative body 67b are covered by the magnets 73 corresponding to each other. All of the magnets 73 are hidden by the first decorative body 67a or the second decorative body 67b. None of the magnets 73 are visually recognized from the flat surface 63. Here, for example, if the magnet 73 is formed of a transparent material, the first decorative body 67a and the second decorative body 67b can be omitted. In addition, the lower surface of the upper plate material 62a may be provided with an opaque decoration, leaving a transparent window. Printing or deposition can be used to apply the decoration. The window can be, for example, a contour of an image on an instant film 66. The image can be observed through the window. Transparency is blocked around the window. The magnet 73 can be hidden.

A first magnetic body 74 is fixed to the lower plate 62b based on the magnetic force of the magnet 73. The first magnetic body 74 is embedded in the upper surface of the lower plate 62b, for example. The first magnetic body 74 may have an outline that overlaps with the magnet 73 when the upper plate 62a is overlapped with the lower plate 62b. The lower plate 62b is fixed to the lower surface of the upper plate 62a by the action of magnetic force. The instant film 66 is sandwiched between the upper plate 62a and the lower plate 62b overlapped with the upper plate 62a. A magnet may be used instead of the first magnetic body 74. In this case, the magnet of the lower plate 62b may be faced to the magnet 73 with the magnetic pole opposite to that of the magnet 73 of the upper plate 62a. The magnet 73 and the first magnetic body 74 may be interchanged between the upper plate 62a and the lower plate 62b.

A second magnetic body 75 is fixed to the upper box body 13. The second magnetic body 75 is disposed below each of the first magnetic bodies 74. The magnetic force of the magnet 73 acts on the second magnetic body 75 via the first magnetic body 74. In this way, the upper plate material 62a and the lower plate material 62b can be fixed in the recess 61 by the action of the magnetic force. Here, a magnet may be used instead of the second magnetic body 75. In this case, the magnet of the upper box body 13 may be faced to the magnet with the opposite magnetic pole to the magnet of the lower plate material 62b.

As shown in FIG. 11, a light irradiation circuit 38 according to a first specific example is constructed in the inner box 11, including an LED lamp 33, a battery 35, and a switch 36. 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 goes out.

As shown in FIG. 12, 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. A battery 35 is connected to the audio circuit 48. The audio circuit 48 operates by receiving the voltage from the battery 35.

The microphone 46 detects air vibrations based on sound and converts them into an audio signal (electrical signal). The generated audio signal is recorded, for example, in the memory 49. For example, an EEPROM can be used for the memory 49. The memory 49 is preferably a memory that allows the 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 arranged corresponding to the position of the microphone 46 and connects outside air to the microphone 46.

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 sense of 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 top plate 16a and the decorative top plate 24a, for example. The top plate 16a or the decorative top plate 24a may have a through hole arranged corresponding to the position of the speaker 47 and connecting outside air to the speaker 47.

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 shared between 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.

The audio circuit 48 is connected to the recording switch 52. 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. 13, 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 pressed. When the button is released, 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 (erasure of audio due to 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.

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 the switch 36, the first blade 27 or second blade 28 of the hinge 26, the battery 35, the microphone 46, the speaker 47, etc. may be electrically connected to the wiring pattern on the printed circuit board by electrical wires such as vinyl-coated wires. The printed circuit board may be housed in the battery chamber 34, for example.

Next, the function of the inner box 11 will be described. As shown in FIG. 3, when the upper box body 13 is 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 appearance of the closed inner box 11. The diamond grains 23 are out of the view of the observer.

At this time, as shown in FIG. 7, 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 off state. The operation of the audio circuit 48 is maintained in a stopped state.

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 glow.

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 the farther it is from the axis of rotation. As shown in FIG. 5, 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).

When the upper box body 13 reaches the open position, as shown in FIG. 8, 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.

After the upper box body 13 is opened, the diamond grains 23 are observed to shine transparently for a while, and then the diamond grains 23 change color from transparent to blue. In this way, a light effect is created in response to the opening action 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, so that 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 color change of the diamond grains 23.

When the second time has elapsed since the start of the ultraviolet irradiation, the audio circuit 48 plays 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.

When the switch 36 is turned off, the LED lamp 33 goes out. The audio circuit 48 stops supplying the audio signal. Audio playback ends.

Prior to giving the gift, the giver's voice is recorded in the inner box 11. To record, the upper box 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 recording switch 52 button, the voice recording ends.

Here, the fabric material 18a of the cushioning material 18 is preferably colored black or dark blue. With such coloring, even if the light from the LED lamp 33 is slightly mixed with 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.

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 inside the store permeate the first piece of paper 69a and the second piece of paper 69b of the inner box 11. In this way, the scent inside the jewelry shop becomes associated with the inner box 11. When a ring 21 is purchased at the jewelry shop, the scene of the purchase can be linked to the scent. The scent remains strong in the memories of the man and the woman.

When the inner box 11 is taken out of the outer box 102, the scent of a jewelry shop wafts around the inner box 11. The fragrant components of the first piece of paper 69a and the second piece of paper 69b leak out from the gap 71 into the space 65. The leaked fragrant components are dispersed from the space 65 upwards of the upper box body 13. The woman can enjoy the scent every time she takes out the inner box 11. If the woman received the ring 21 as a gift, she will remember the joy she felt when 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 she felt when receiving a gift. The man's impression can be strongly imprinted on the woman.

The inner box 11 can be displayed in a room as a source of fragrance. The woman can see the inner box 11 frequently in the room. In this way, the woman can frequently recall the joy she felt when receiving the gift. The man's impression can be strongly imprinted on the woman.

The enclosure 64 allows a tray to be formed on the top surface of the upper box body 13. Small items such as rings 21 and key chains can be placed on the upper plate material 62a. The enclosure 64 allows the small items to be held on the upper plate material 62a. Since such a tray is used daily, women can see the inner box 11 frequently. The emotions felt when receiving a 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 those who view the inner box 11.

The lower plate 62b is fixed to the upper plate 62a by the magnetic force of the magnet 73. The first and second pieces of paper 69a and 69b containing the fragrant components are sandwiched between the upper plate 62a and the lower plate 62b. Access to the outer periphery of the upper plate 62a and the lower plate 62b is permitted from the space 65. The upper plate 62a and the lower plate 62b can be easily pulled up from the recess 61 by applying an external force to the outer periphery of the upper plate 62a and the lower plate 62b. The fragrance unit 62 can be easily removed from the upper box body 13. At this time, the lower plate 62b can be separated from the upper plate 62a against the magnetic force, so that the first and second pieces of paper 69a and 69b can be replenished with the fragrant components. Alternatively, the first and second pieces of paper 69a and 69b may be replaced with pieces containing a sufficient amount of fragrant components. In this way, women can enjoy the scent from the inner box 11 forever. The magnets and magnetic materials may be interchanged between the upper plate 62a and the lower plate 62b. The space 65 may be formed to be thin and extend along the left and right edges of the upper plate 62a and the lower plate 62b, and may be formed to be large enough to receive, for example, a finger ring 21. In this case, a hard tool may be inserted into the space 65 to remove the fragrance unit 62. The space 65 may be formed to be large enough to allow the fingertip to reach the lower plate 62b.

The fragrance unit 62 is fixed in the recess 61 by the action of the magnet 73. The magnetic field lines of the magnet 73 can flow through the first magnetic body 74 and the second magnetic body 75. The fragrance unit 62 can be held well within the recess 61 regardless of whether the upper box body 13 is open or closed.

For example, at a jewelry shop, the scene of the purchase can be captured with an instant camera. The scene of the purchase can be developed on the spot onto an instant film 66. The upper plate 62a and the lower plate 62b serve 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 upper plate 62a. The image can further enhance the emotion felt when receiving the gift.

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. Opportunities for the inner box 11 to be taken out increase. Opportunities for viewing images on the instant film 66 increase. With ordinary products, the packaging box is often discarded once the product begins to be used.

Similarly, the inner box 11 according to this embodiment plays back recorded sound. Since the sound production effect is thus realized, the owner of the ring 21 keeps the inner box 11 rather than 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.

Figure 14 shows a schematic structure of a fragrance unit 77 according to a second example. A plate 78 is fixed in the recess 61 by fitting to the contour of the recess 61. The instant film 66 and the first and second pieces of paper 69a and 69b are placed on a horizontal surface 68 defined by the bottom of the recess 61. The plate 78 is placed on the horizontal surface 68 and covers the instant film 66 and the first and second pieces of paper 69a and 69b. The plate 78 contacts the inner wall surface of the recess 61, for example, at its upper and lower edges in a plan view. The plate 78 can be made of, for example, a transparent hard acrylic plate. The surface of the plate 78 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 the horizontal surface including the flat surface 63 to fit the contour of the recess 61. For each edge of the contour, the wall surface 64a continues from the inner wall surface of the recess 61 within one vertical plane. The wall surface 64a can guide the descent of the plate material 78 in the vertical direction. In this way, the plate material 78 and the enclosure 64 cooperate to form a tray on the top surface of the upper box body 13. As described above, the recess 61 defines a space 65 that is adjacent to the outer periphery of the plate material 78 and opens in a horizontal plane including the flat surface 63. The space 65 is located outside the left and right edges when viewed from above.

A magnetic body 79 is fixed to the upper box body 13. The magnetic body 79 is disposed below each of the magnets 73. The magnetic force of the magnets 73 acts on the magnetic body 79. In this way, the plate material 78 can be fixed in the recess 61 by the action of the magnetic force. Here, the lower plate material 62b can be omitted. A gap is formed between the upper plate material 62a and the horizontal surface 68 according to the thickness of the instant film 66 and the first piece of paper 69a and the second piece of paper 69b. The gap is connected to the space 65. A magnet may be used instead of the magnetic body 79. In this case, the magnet of the upper box body 13 may be faced to the magnet 73 with the magnetic pole opposite to that of the magnet 73 of the upper plate material 62a.

Figure 15 shows a schematic structure of a fragrance unit 82 according to a third specific example. The upper plate 62a and the lower plate 62b are overlapped with surface contact. The instant film 66 and the first and second pieces of paper 69a and 69b are placed in a recess 83 formed in either the upper plate 62a or the lower plate 62b. The lower plate 62b has openings 84 formed at positions corresponding to the first and second pieces of paper 69a and 69b, respectively. The openings 84 penetrate the lower plate 62b in the vertical direction. The first and second pieces of paper 69a and 69b are exposed to the corresponding openings 84, respectively. Each opening 84 is connected to a recess space 85 in contact with the lower surface of the lower plate 62b. The second magnetic body 75 of the upper box body 13 can hold the lower plate 62b at a position vertically away from the bottom of the recess 61. The aroma components of the first piece of paper 69a and the second piece of paper 69b can leak out from the opening 84 into the space 85 inside the recess. The leaked aroma components can be released from the space 65 toward the top of the upper box body 13.

Here, as shown in FIG. 16, a gap 71 may be formed between the upper plate 62a and the lower plate 62b according to the thickness of the first and second pieces of paper 69a and 69b and the instant film 66, as described above. The aroma components of the first and second pieces of paper 69a and 69b can leak into the space 65 not only from the opening 84 and the space 85 inside the recess, but also from the gap 71. The release of the aroma can be intensified. The second magnetic body 75 of the upper box body 13 can be made of, for example, a stainless steel plate that extends to the contour of the recess 61. The upper surface of the second magnetic body 75 is covered with a sticker 17 that extends continuously to the contour of the recess 61. A magnet 87 is fixed to the lower plate 62b at a position horizontally out of the opening 84. The magnet 87 is fixed to the second magnetic body 75. The magnet 87 fixes the fragrance unit 82 to the upper box body 13. Instead of the second magnetic body 75, the magnet 87 can hold the lower plate 62b at a position vertically away from the bottom of the recess 61.

Figure 17 shows a schematic structure of a fragrance unit 88 according to a fourth example. The upper plate 62a defines a through hole 89. The through hole 89 opens on the upper surface of the upper plate 62a. The lower end of the through hole 89 overlaps the first piece of paper 69a or the second piece of paper 69b inside the contour of the first piece of paper 69a or the second piece of paper 69b. The fragrant components of the first piece of paper 69a and the second piece of paper 69b can be diffused from the through hole 89 toward the top of the upper plate 62a. The fragrance wafts around the inner box 11.

Here, since the through hole 89 of the upper plate 62a overlaps with the first piece of paper 69a or the second piece of paper 69b inside the contour of the first piece of paper 69a or the second piece of paper 69b, the upper plate 62a can press the first piece of paper 69a and the second piece of paper 69b on the horizontal surface 68 over the entire contour of the through hole 89. Therefore, the first piece of paper 69a and the second piece of paper 69b can be prevented from rippling inside the through hole 89. The flat first piece of paper 69a and the second piece of paper 69b can provide an aesthetic appearance to the horizontal surface 68. Since the first piece of paper 69a and the second piece of paper 69b close the through hole 89 without any gaps, the fragrance components of the first piece of paper 69a and the second piece of paper 69b can efficiently drift upward from the through hole 89. If a gap occurs, the fragrance components will leak out from the gap to places other than the through hole 89.

As shown in FIG. 18, the upper plate material 62a may be formed with a protrusion 91 that protrudes from the lower surface of the upper plate material 62a and bites into the first piece of paper 69a and the second piece of paper 69b on the horizontal surface 68. The protrusion 91 continues around the entire circumference along the contour of the through hole 89, for example. When the upper plate material 62a presses the first piece of paper 69a and the second piece of paper 69b against the horizontal surface 68, the pressure of the pressure can be concentrated on the protrusion 91. As a result, the protrusion 91 can bite into the first piece of paper 69a and the second piece of paper 69b. The first piece of paper 69a and the second piece of paper 69b can be sandwiched between the upper plate material 62a and the lower plate material 62b (horizontal surface 68) with strong pressure. The movement of the first piece of paper 69a and the second piece of paper 69b in the horizontal direction can be prevented. The first piece of paper 69a and the second piece of paper 69b can be held well. The first piece of paper 69a and the second piece of paper 69b can be prevented from rippling inside the through hole 89. In addition, a protrusion 92 may be formed on the upper plate material 62a at a position away from the through hole 89. The protrusion 92 can be very useful in preventing the first piece of paper 69a and the second piece of paper 69b from moving horizontally. The protrusions 91 and 92 can be molded integrally with the upper plate material 62a, for example.

Figure 19 shows the schematic configuration of the light irradiation circuit according to the second specific example. The light irradiation circuit 43 includes an NPN transistor TR1 connected to the 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 conductive, the voltage applied to the base B of the NPN transistor TR1 gradually increases due to the action of the time constant circuits R1 and C1. When the voltage at base B of NPN transistor TR1 reaches a specified value during the voltage rise, current flows into collector C. After a specified time has elapsed, the voltage applied to base B of NPN transistor TR1 remains constant. When switch 36 is turned off, the charge in capacitor C1 is discharged through second resistor R2.

The hold circuit 51 of the sound reproduction unit 45 holds the sound reproduction until a predetermined time (hereinafter referred to as the "third time") has elapsed after the ultraviolet light reaches the maximum light intensity. The sound circuit 48 and the light irradiation circuit 43 share the battery 35 and the switch 36. 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 the "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 begins to be maintained at a 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.

The LED lamp 33, NPN transistor TR1, capacitor C1, first and second resistors R1, R2, 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 the wiring pattern on the printed circuit board by electrical wires such as vinyl-coated wires. The printed circuit board may be housed in battery chamber 34, for example.

In the light irradiation circuit 43 according to the second specific example, after the upper box 13 reaches the open position and the switch 36 becomes conductive, 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 became conductive (ON operation). Current flows into the collector C of the NPN transistor TR1, and the LED lamp 33 begins to light up. Therefore, an observer of the inner box 11 can observe the diamond grains 23 shining transparently for a while after the upper box 13 is opened.

The voltage applied to the base B of the NPN transistor TR1 gradually increases 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 change in color of the diamond grains 23.

When the second time has elapsed since the start of the ultraviolet irradiation, 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 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.

When the switch 36 is turned off, the LED lamp 33 goes out. The audio circuit 48 stops supplying the audio signal. Audio playback ends. The charge in the capacitor C1 is discharged through the second resistor R2.

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 number 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 number 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.

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 13 when the upper box 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 achieve the same functions as described above. Furthermore, the operation of the switch 36 may not only be linked to the upper box 13 being in the open position as described above, but may also be linked to the upper box 13 being in the closed position. Additionally, the functions of the light irradiation circuits 38, 43, the sound circuit 48, and the hold circuit 51 may be realized by software executed by a microprocessor (MPU).
