DETAILED DESCRIPTION OF THE INVENTION

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention (hereinafter referred to as the present embodiment) will be described below with reference to the accompanying drawings. In this specification, the same elements are designated by the same reference numerals throughout.

[0010] The seafood delivery box according to this embodiment will be described with reference to FIGS. 1 to 5.

[0011] As shown in FIGS. 1 to 5, the seafood delivery box according to this embodiment is a delivery box for delivering seafood and the like, and includes a box body 11, an annular sealing frame 12, and a cover .

[0012] As shown in Figures 1 to 5, the box body 11 has a bottom wall formed in a rectangular shape when viewed from above, a side wall erected from one outer edge of the bottom wall, an opposing wall erected from the other outer edge of the bottom wall so as to face the side wall, and a pair of connecting walls erected from the remaining two outer edge of the bottom wall so as to face each other and connect the side wall and the opposing wall.

[0013] An accommodation chamber 27 is formed inside the box body 11. An opening is formed at the upper end of the box body 11, surrounded by the upper ends of the side walls, the upper ends of the opposing walls, and the upper ends of the pair of connecting walls.

[0014] 1 to 3, the annular seal frame 12 is provided on the upper end side of the box body 11 so as to be located on the outer periphery of the opening. Specifically, the annular seal frame 12 is provided on the upper end sides of the side walls, the upper end sides of the opposing walls, and the upper end sides of the pair of connecting walls (i.e., the upper end sides of the peripheral walls of the annular seal frame 12). An annular seal groove 13 is formed between the annular seal frame 12 and the box body 11 (specifically, the side walls, the opposing walls, and the pair of connecting walls of the box body 11). This makes it possible to easily form the seal groove 13 without reducing the volume of the storage chamber 27 inside the box body 11.

[0015] As shown in FIGS. 1 to 3, cover 14 is a lid for closing the opening of box body 11. An annular elastic seal member 15 that engages with annular seal groove 13 is provided on the underside of cover 14. When the opening of box body 11 is closed by cover 14, annular elastic seal member 15 engages with annular seal groove 13. Specifically, in this state, annular elastic seal member 15 is press-fitted into annular seal groove 13. This improves the sealing performance of the seafood delivery box, thereby preventing seawater from leaking from the seafood delivery box when seawater is stored therein, without reducing the volume of storage chamber 27 within box body 11.

[0016] The cover 14 is provided with a valve 16 that penetrates the top and bottom surfaces of the cover 14. The valve 16 can be connected to a water supply hose (not shown). When the water supply hose is connected to the valve 16, switching the valve 16 from a closed state to an open state allows seawater or the like to be supplied to the accommodation chamber 27 via the water supply hose.

[0017] The cover 14 is also provided with a pair of mounting plates 21 that face each other and are located outside the annular elastic seal material 15. The pair of mounting plates 21 are provided so as to protrude from the lower surface of the cover 14. Each of the pair of mounting plates 21 is also formed with a pair of positioning holes 22. The seal frame 12 is preferably formed with a pair of guide grooves that guide each of the pair of mounting plates 21 slidably in the up-down direction.

[0018] As shown in FIGS. 1 to 3 , the box 11 is provided with two pairs of mounting pieces 18. Specifically, one pair of mounting pieces 18 is provided on the outer surface of a side wall of the box 11, and the other pair of mounting pieces 18 is provided on the outer surface of the opposing wall of the box 11. A connection hole 19 is formed in each of the mounting pieces 18. A connection pin 17 is inserted into the connection hole 19. When the opening of the box 11 is closed by the cover 14, the mounting plate 21 (specifically, the tip side of the mounting plate 21) is positioned between the pair of mounting pieces 18, and the connection pin 17 is inserted into the positioning hole 22 and the pair of connection holes 19, thereby positioning the cover 14 with respect to the box 11. This makes it easy to position the cover 14 with respect to the box 11.

[0019] 1 to 3, the box body 11 is provided with a pair of stoppers 31. Specifically, one stopper 31 is provided on the outer surface of a side wall of the box body 11, and the other stopper 31 is provided on the outer surface of the opposing wall of the box body 11. More specifically, one stopper 31 is provided on an extension of the straight line on which one pair of mounting pieces 18 is arranged, and the other stopper 31 is provided on an extension of the straight line on which the other pair of mounting pieces 18 is arranged. When the connection pin 17 is inserted into one of the connection holes 19 and the base end of the connection pin 17 abuts against the stopper 31, the mounting plate 21 can reach between the pair of mounting pieces 18. This prevents the connection pin 17, supported by one of the mounting pieces 18, from coming off the connection hole 19 of the mounting piece 18.

[0020] As shown in Fig. 4, elastic cushioning material 30 is provided on the inside of the side wall of box 11 (specifically, the entire inside surface of the side wall), which prevents seafood stored in storage chamber 27 from colliding with the side wall of box 11 and being damaged during delivery.

[0021] As shown in FIG. 4, an oxygen supply port 29 is formed on the inside of the opposing wall of the box body 11. The oxygen supply port 29 is located on the lower side of the storage chamber 27. The opposing wall is also provided with a water level detection unit 25 that detects the level of seawater in the storage chamber 27. The water level detection unit 25 extends in the up-down direction. The oxygen supply port 29 is located below the water level detection unit 25. This allows the oxygen supply port 29 to be located close to the bottom wall of the storage chamber 27, so that oxygen can be supplied to the seawater via the oxygen supply port 29 even when the amount of seawater stored in the storage chamber 27 becomes low.

[0022] Additionally, an isolation frame member 26 is provided on the opposing wall of the box body 11, surrounding both the oxygen supply port 29 and the water level detection unit 25. The isolation frame member 26 is composed of a plurality of isolation frames (specifically, U-shaped frames) arranged along the vertical direction.

[0023] In this way, by integrating the water level detection unit 25 and the oxygen supply port 29 and providing them inside the opposing wall and surrounding them with the isolation frame member 26, it is possible to prevent the water level detection unit 25 from coming into contact with the seafood, causing the water level detection unit 25 to malfunction, or the seafood from blocking the oxygen supply port 29, preventing oxygen from being supplied to the storage chamber 27. Furthermore, because the water level detection unit 25 and the oxygen supply port 29 are integrated into one location, it is possible to surround both the water level detection unit 25 and the oxygen supply port 29 without increasing the size of the isolation frame member 26. As a result, a large volume can be secured for the storage chamber 27.

[0024] The oxygen supply cylinder 24 has a drive pump (not shown) and is replaceably provided adjacent to the outside of the opposing wall of the box body 11. A supply pipe 23 is provided between the oxygen supply cylinder 24 and the oxygen supply port 29. The supply pipe 23 supplies oxygen from the oxygen supply cylinder 24 to the oxygen supply port 29. This allows the supply pipe 23 to supply oxygen from the oxygen supply cylinder 24 to the oxygen supply port 29 during delivery. Furthermore, when the oxygen stored in the oxygen supply cylinder 24 runs out, the oxygen supply cylinder 24 can be replaced.

[0025] As shown in Fig. 4, an oxygen detector 28 is provided on the inside of one connecting wall of the box body 11. The oxygen detector 28 is a detector that detects the amount of oxygen in the storage chamber 27 (specifically, the amount of oxygen in seawater). As shown in Figs. 1 to 3, a controller 20 that is electrically connected to the oxygen detector 28 and the drive pump of the oxygen supply cylinder 24 is provided on the outside of one connecting wall of the box body 11. The controller 20 is a control unit that controls the drive pump of the oxygen supply cylinder 24.

[0026] In this way, by providing the oxygen detection unit 28 and the controller 20 on the inside and outside of one of the connecting walls of the box body 11, respectively, the wiring for electrically connecting the oxygen detection unit 28 and the controller 20 can be made short, thereby simplifying the wiring.

[0027] Specifically, the controller 20 controls the driving of the drive pump of the oxygen supply cylinder 24 based on the amount of oxygen detected by the oxygen detection unit 28 and the water level detected by the water level detection unit 25. A memory unit (not shown) of the controller 20 stores a program and an algorithm for controlling the drive pump of the oxygen supply cylinder 24. The memory unit also temporarily stores information related to the amount of oxygen and the water level. The memory unit also stores a table for controlling the drive pump of the oxygen supply cylinder 24. The table includes corresponding water levels, first oxygen amounts, and second oxygen amounts set in stages. The second oxygen amount is greater than the first oxygen amount. Here, the first oxygen amount refers to an oxygen amount that indicates a state in which seafood is short of oxygen at the corresponding water level, and the second oxygen amount refers to an oxygen amount that indicates a state in which seafood is sufficiently oxygenated at the corresponding water level.

[0028] More specifically, the controller 20 controls the driving of the drive pump of the oxygen supply cylinder 24 based on the amount of oxygen detected by the oxygen detection unit 28, the water level detected by the water level detection unit 25, and a table stored in the memory unit of the controller 20.

[0029] More specifically, when the amount of oxygen detected by the oxygen detection unit 28 is lower than the first amount of oxygen corresponding to the water level detected by the water level detection unit 25, the controller 20 drives the drive pump of the oxygen supply cylinder 24 to supply oxygen from the oxygen supply cylinder 24 to the seawater in the storage chamber 27 via the supply piping 23 and the oxygen supply port 29 so that the amount of oxygen in the storage chamber 27 becomes the second amount of oxygen corresponding to the water level detected by the water level detection unit 25.

[0030] On the other hand, when the amount of oxygen detected by the oxygen detection unit 28 is equal to or greater than the first amount of oxygen associated with the water level detected by the water level detection unit 25, the controller 20 controls not to drive the drive pump of the oxygen supply cylinder 24. In this case, the controller 20 determines that there is enough oxygen for the seafood at the associated water level.

[0031] As a result, when the seawater stored in storage chamber 27 runs short of oxygen, controller 20 can automatically supply an appropriate amount of oxygen from oxygen supply cylinder 24 to the seawater in storage chamber 27 via supply piping 23 and oxygen supply port 29. As a result, the freshness of the seafood stored in storage chamber 27 can be maintained at the time of delivery, and the value of the seafood can be maximized.

[0032] (Action and effect) Next, the effects of the above-described embodiment will be described.

[0033] The seafood delivery box of this embodiment is a box body 11 with an opening formed at the top end, box body 11 with an annular sealing frame 12 provided on the outer periphery of the opening, an annular sealing groove 13 formed between the sealing frame 12 and box body 11, an annular elastic sealing material 15 that engages with the sealing groove 13, and a cover 14 that closes the opening, and a storage chamber 27 for storing seafood, seawater, or ice is formed within box body 11, and an elastic cushioning material 30 is provided on the inside of the side wall of box body 11.

[0034] This configuration improves the sealing performance of the seafood delivery box, thereby preventing seawater from leaking from the seafood delivery box when it is stored, without reducing the volume of the storage chamber 27 inside the box body 11.

[0035] In addition, in this embodiment, the seafood delivery box is equipped with a pair of mounting plates 21 formed on the cover 14 so as to face each other and be positioned outside the annular elastic sealing material 15, a pair of positioning holes 22 formed in each of the pair of mounting plates 21, two pairs of mounting pieces 18 provided on the box body 11 so as to be positioned on a pair of opposing faces of the box body 11, connection holes 19 formed in each mounting piece 18, and connection pins 17 that are capable of passing through the positioning holes 22 and the connection holes 19.When the opening of the box body 11 is closed by the cover 14, the mounting plates 21 are positioned between the pair of mounting pieces 18, and the connection pins 17 are inserted into the positioning holes 22 and the connection holes 19, thereby positioning the cover 14 relative to the box body 11.

[0036] According to this configuration, the cover 14 can be easily positioned relative to the box body 11.

[0037] In addition, in this embodiment, the seafood delivery box is equipped with an oxygen supply port 29 formed on the inside of the opposing wall that faces the side wall on which the elastic cushioning material 30 of the box body 11 is provided, and an isolation frame member 26 provided on the opposing wall so as to surround the oxygen supply port 29.

[0038] According to this configuration, oxygen can be supplied into the storage chamber 27 from the oxygen supply port 29. In addition, since the oxygen supply port 29 is surrounded by the isolation frame member 26, it is possible to prevent seafood from blocking the oxygen supply port 29 and preventing oxygen from being supplied to the storage chamber 27.

[0039] In addition, in this embodiment, the seafood delivery box extends in the vertical direction and is provided on the opposing wall so as to be surrounded by an isolation frame member 26, and is equipped with a water level detection unit 25 that detects the water level in the storage chamber 27, the isolation frame member 26 is composed of a plurality of isolation frames arranged in the vertical direction, and the oxygen supply port 29 is located below the water level detection unit 25.

[0040] This configuration makes it possible to prevent the water level detection unit 25 from coming into contact with the seafood and causing a malfunction of the water level detection unit 25. Furthermore, because the water level detection unit 25 and the oxygen supply port 29 are integrated into one location, it is possible to surround both the water level detection unit 25 and the oxygen supply port 29 without increasing the size of the isolation frame member 26. As a result, it is possible to ensure a large volume for the storage chamber 27. Furthermore, because the oxygen supply port 29 can be provided near the bottom wall of the storage chamber 27, oxygen can be supplied to the seawater through the oxygen supply port 29 even when the amount of seawater stored in the storage chamber 27 decreases.

[0041] In addition, in this embodiment, the seafood delivery box is equipped with an oxygen supply cylinder 24 that is replaceably arranged adjacent to the outside of the opposing wall, and a supply pipe 23 that supplies oxygen from the oxygen supply cylinder 24 to the oxygen supply port 29.

[0042] According to this configuration, during delivery, the supply pipe 23 can supply oxygen from the oxygen supply cylinder 24 to the oxygen supply port 29. Furthermore, when the oxygen stored in the oxygen supply cylinder 24 runs out, the oxygen supply cylinder 24 can be replaced.

[0043] In addition, in this embodiment, the seafood delivery box is provided with an oxygen detection unit 28 that is provided inside the connecting wall that connects the side wall and the opposing wall of the box body 11 and detects the amount of oxygen in the storage chamber 27, and a controller 20 that is provided outside the connecting wall so as to be electrically connected to the oxygen detection unit 28 and the drive pump of the oxygen supply cylinder 24.

[0044] According to this configuration, by providing the oxygen detection unit 28 and the controller 20 on the inside and outside of one of the connecting walls of the box body 11, respectively, the wiring for electrically connecting the oxygen detection unit 28 and the controller 20 can be made short, thereby simplifying the wiring.

[0045] In this embodiment, the controller 20 controls the driving of the drive pump of the oxygen supply cylinder 24 based on the amount of oxygen detected by the oxygen detector 28 and the water level detected by the water level detector 25.

[0046] In addition, in this embodiment, when the amount of oxygen detected by the oxygen detection unit 28 is lower than the first oxygen amount corresponding to the water level detected by the water level detection unit 25, the controller 20 drives the drive pump of the oxygen supply cylinder 24 to supply oxygen from the oxygen supply cylinder 24 to the storage chamber 27 via the supply piping 23 and the oxygen supply port 29 so that the amount of oxygen in the storage chamber 27 is greater than the first oxygen amount and is the second oxygen amount corresponding to the water level detected by the water level detection unit 25.

[0047] According to this configuration, when the seawater stored in storage chamber 27 runs short of oxygen, controller 20 can automatically supply an appropriate amount of oxygen from oxygen supply cylinder 24 to the seawater in storage chamber 27 via supply piping 23 and oxygen supply port 29. As a result, the freshness of the seafood stored in storage chamber 27 can be maintained at the time of delivery, and the value of the seafood can be maximized.

[0048] (Variation) In this embodiment, the controller 20 is configured to control the driving of the drive pump of the oxygen supply cylinder 24 based on the amount of oxygen detected by the oxygen detection unit 28, the water level detected by the water level detection unit 25, and a table stored in the memory unit of the controller 20, but is not limited to this. For example, the controller 20 may be configured to control the driving of the drive pump of the oxygen supply cylinder 24 based on the amount of oxygen detected by the oxygen detection unit 28 and a predetermined first oxygen amount and a predetermined second oxygen amount stored in the memory unit of the controller 20.

[0049] In this case, when the amount of oxygen detected by oxygen detection unit 28 is lower than a predetermined first amount of oxygen, controller 20 drives the drive pump of oxygen supply cylinder 24 to supply oxygen from oxygen supply cylinder 24 to seawater in storage chamber 27 via supply piping 23 and oxygen supply port 29 so that the amount of oxygen in storage chamber 27 becomes a predetermined second amount of oxygen that is higher than the predetermined first amount of oxygen. Here, the predetermined first amount of oxygen means an amount of oxygen that indicates a state in which there is insufficient oxygen for the seafood, and the predetermined second amount of oxygen means an amount of oxygen that indicates a state in which there is sufficient oxygen for the seafood.

[0050] The present embodiment has been described above, but the above-described embodiment merely illustrates some of the application examples of the present invention, and is not intended to limit the technical scope of the present invention to the specific configurations of the above-described embodiment.
