Description

Technical Field

[0001] The present invention relates to a simple pressure vessel for accommodating captured deep-sea organisms, and particularly to a simple pressure vessel having a function of reducing the symptoms of decompression sickness in deep-sea organisms.

Background Art

[0002] When displaying deep-sea organisms in facilities such as aquariums and aquarium shops, for example, as described in Non-Patent Document 1, deep-sea organisms captured by fishing methods such as bottom trawling, fly-line fishing, cage fishing, and angling are placed one by one in collection bags and transferred into a cold storage container, and then transported to facilities such as aquariums and aquarium shops in a state of being accommodated in the cold storage container.

[0003] The above-mentioned cold storage container has cooling means such as a cooler and a light-shielding function for blocking sunlight, and by setting the inside to approximately the same temperature as the habitat of the deep-sea organisms by the operation of the cooling means and preventing sunlight from hitting the deep-sea organisms by the light-shielding function, it is possible to prevent the collected deep-sea organisms from being affected by temperature and sunlight and the survival rate from decreasing.

[0004] Also, after transportation to facilities such as aquariums and aquarium shops, the captured deep-sea organisms are transferred to a water tank installed in the backyard of the facility, and by gradually decompressing them with the pressurizing means of the water tank, the deep-sea organisms can be made to be in a state where they can be reared even under low pressure, and then transferred to a display water tank to start the display.

[0005] However, in the method of transporting deep-sea organisms collected by the above means to facilities such as aquariums, a large cold storage container is required, and cooling means such as a cooler is required to keep the temperature of the large cold storage container constant. Also, since it is necessary to create a high-pressure environment close to the habitat of deep-sea organisms in the water tank installed in the backyard or the like, a water tank with excellent pressure resistance must be used, resulting in high equipment costs and an increase in the costs required for collecting deep-sea organisms.

[0006] On the other hand, when deep-sea organisms are caught by fishing, the swim bladder of the caught organism may expand due to the rapid change in water pressure, causing the organism to float belly-up on the surface of the sea (decompression sickness), making it difficult for it to survive.

[0007] Therefore, it is necessary to release caught deep-sea organisms to increase their survival rate by using methods such as inserting a special needle into their abdomen to release the gas accumulated in their swim bladder and return them to their original state, or placing the caught deep-sea organisms in a net with a weight attached and returning them to the vicinity of their original seawater area, forcibly returning their inflated abdomens to their original state with water pressure and releasing them. However, this process is time-consuming and laborious.

[0008] Patent Document 1 describes an invention relating to a breeding tank. This breeding tank comprises a tank body, a sealing lid that closes the upper opening of the tank body, and a high-pressure, high-oxygen-concentration air injection means that generates high-pressure, high-oxygen-concentration air with an oxygen concentration higher than that of normal air and a pressure higher than atmospheric pressure, and injects the generated high-pressure, high-oxygen-concentration air into the gap between the water surface in the tank body and the sealing lid.

[0009] This type of aquarium configuration allows for increased oxygen concentration in the water through a simple design, promoting the growth of fish and shellfish and enabling the continuous keeping of aquatic life.

[0010] However, because a means of injecting high-pressure, high-oxygen air is required in addition to the tank itself, the location where these can be installed is limited, making it unsuitable for simply storing deep-sea organisms caught on a ship or similar vessel. Furthermore, it cannot be used when releasing deep-sea organisms that have been caught by fishing.

[0011] Reference 2 describes an invention relating to a live fish water pressure vessel. This live fish water pressure vessel comprises a water pressure vessel body, an inlet / outlet hatch, a compressed air intake, a drain port, a water inlet, and an air pressure regulating valve provided on the water pressure vessel body.

[0012] A live fish water pressure vessel with this configuration is a large-scale facility with the container body made of reinforced glass, concrete, FRP, etc., so it can ensure strength for transportation.

[0013] However, because the overall size increases, it cannot be used for simple storage of deep-sea organisms caught on board a ship or similar vessel. It also cannot be used when releasing deep-sea organisms that have been caught by fishing. [Prior art documents] [Patent Documents]

[0014] [Patent Document 1] Utility Model Registration No. 3220005 Publication [Patent Document 2] Japanese Patent Publication No. 2004-65157 [Non-patent literature]

[0015] [Non-Patent Document 1] Numazu Port Deep Sea Aquarium website (searched March 3, 2026), Internet (https: / / www.numazu-deepsea.com / concept / challenge) [Overview of the project] [Problems that the invention aims to solve]

[0016] This invention has been made in view of the above-mentioned conventional problems, and aims to provide a simple pressurized container that has a simple structure and low equipment costs, can quickly alleviate the decompression sickness of deep-sea organisms captured on board ships, etc., can transport deep-sea organisms to aquariums etc. at low cost with a high survival rate, and can also be easily released with a high survival rate when released from ships etc. [Means for solving the problem]

[0017] To solve the above-mentioned problems, the first invention is a simple pressurized container for housing deep-sea organisms, comprising a container body having a containment chamber for housing the deep-sea organisms, capable of pressurizing the containment chamber to a level that can alleviate the symptoms of decompression sickness in the deep-sea organisms, and having a size and weight that can be carried by hand, and a manual pressurizing pump that is detachably attached to the container body and capable of pressurizing the inside of the container body to a level that can alleviate the symptoms of decompression sickness in the deep-sea organisms.

[0018] According to the simple pressurized container of this invention, the contents of the container body can be pressurized to a level sufficient to alleviate the symptoms of decompression sickness in deep-sea organisms by pressurizing with a manual pressurizing pump. Therefore, by placing deep-sea organisms exhibiting symptoms of decompression sickness in the contents of the container body and pressurizing the contents of the contents with a pressurizing pump, the symptoms of decompression sickness in the deep-sea organisms can be alleviated. Furthermore, since the container body is set to a size and weight that can be carried by hand, it can be easily transported onto a ship or other vessel when capturing deep-sea organisms on board, and the survival rate of the deep-sea organisms captured on board can be easily increased. Moreover, when releasing deep-sea organisms into the sea on board, they can be easily released in a state with a high survival rate.

[0019] Furthermore, the second invention is a simple pressurized container described in the first invention, characterized in that the container body is made of a thermoplastic engineering plastic having heat resistance from -40°C to 120°C and cold resistance, and a compressive strength of approximately 60 to 90 MPa.

[0020] According to the simplified pressurized container of this invention, the container body has sufficient heat resistance, cold resistance, and compressive strength, so the inside of the container body can be pressurized to a level that can alleviate the symptoms of decompression sickness in deep-sea organisms. Therefore, the symptoms of decompression sickness in deep-sea organisms can be alleviated from the time they are captured until they are transported to facilities such as aquariums, thereby significantly increasing the survival rate of deep-sea organisms.

[0021] Moreover, the third invention is the simplified pressurized container described in the second invention, wherein the pressurizing pump comprises a pump body that expands and contracts a bellows by manual pressing to supply compressed air into the accommodation chamber of the container body.

[0022] According to the simplified pressurized container of the present invention, by expanding and contracting the bellows by manual pressing and supplying compressed air into the accommodation chamber, it is possible to pressurize to a value that can relieve the symptoms caused by decompression sickness of deep-sea organisms in the accommodation chamber. Therefore, there is no need to prepare complicated and expensive equipment, and the cost of relieving the symptoms caused by decompression sickness of the captured deep-sea organisms can be significantly reduced.

Advantages of the Invention

[0023] As described above, according to the simplified pressurized container of the present invention, the accommodation chamber of the container body can be pressurized to a value that can relieve the symptoms of decompression sickness of deep-sea organisms by a manual pressurizing pump. Therefore, by accommodating a deep-sea organism with decompression sickness symptoms in the accommodation chamber of the container body and pressurizing the accommodation chamber with a pressurizing pump, the symptoms of decompression sickness of the deep-sea organism can be relieved.

[0024] Moreover, since the container body is set to a size and weight that can be easily carried by hand, even when capturing deep-sea organisms on a ship or the like, it can be easily carried onto the ship or the like, and the survival rate of the deep-sea organisms captured on the ship or the like can be easily increased.

[0025] Furthermore, even when releasing deep-sea organisms into the sea on a ship or the like, they can be easily released in a state with an increased survival rate.

[0026] Moreover, since the container body has sufficient heat resistance, cold resistance, and compression strength, the inside of the container body can be pressurized to a value that can relieve the symptoms of decompression sickness of deep-sea organisms, and this pressurized state can be maintained from capture until arrival at facilities such as aquariums. Therefore, the captured deep-sea organisms can be transported to facilities such as aquariums in a state with an increased survival rate and transferred to the water tanks in the aquarium facilities.

[0027] Furthermore, by manually pressing and expanding the bellows to supply compressed air into the containment chamber, the chamber can be pressurized to a level sufficient to alleviate the symptoms of decompression sickness in deep-sea organisms. This eliminates the need for complex and expensive equipment, significantly reducing the cost of mitigating decompression sickness symptoms in captured deep-sea organisms.

[0029] The embodiments of this invention will be described below with reference to the drawings.

[0030] Figures 1 to 7 show one embodiment of the simplified pressurized container according to the present invention. Figure 1 is a schematic diagram showing the whole, Figure 2 is a schematic diagram of the container body, Figure 3 is a schematic diagram of the pressurizing pump, Figure 4 is a plan view of the first cap, Figure 5 is a cross-sectional view of Figure 4 along line AA, Figure 6 is a plan view of the second cap, and Figure 7 is a cross-sectional view of Figure 6 along line BB.

[0031] In other words, as shown in Figures 1 to 3, the simplified pressurized container 1 of this embodiment comprises a container body 2 capable of containing deep-sea organisms caught by fishing methods such as bottom trawling, longline fishing, cage fishing, and angling, and a pressurized pump 25 that can be detachably attached to the container body 2. This simplified pressurized container 1 is used to transport the captured deep-sea organisms to facilities such as aquariums, aquarium shops, and recreational fishing boats.

[0032] As shown in Figures 1 and 2, the container body 2 is a roughly box-shaped container having a sealed storage chamber 3 inside. One end of the upper surface has a first protrusion 4 that projects upward, and the other end has a second protrusion 8 that projects upward. A recess 12 that is one step lower than the first protrusion 4 and the second protrusion 8 is provided between them. A pipe-shaped handle portion 13 is provided between the first protrusion 4 and the second protrusion 8 so as to straddle the recess 12.

[0033] A circular opening 5 is provided in the center of the upper surface of the first protrusion 4, penetrating both the inside and outside. Seawater 45 is filled into the containment chamber 3 of the tank body 2 through this opening 5, and the captured deep-sea organisms 46 (see Figure 10) are placed inside the containment chamber 3. The container body 2 is set to a size and weight that allows it to be carried by hand via the handle 13 when the containment chamber 3 is filled with seawater and the deep-sea organisms 46 are placed inside.

[0034] A cylindrical mounting portion 6 that protrudes upward is integrally provided around the first opening 5, and a male screw 7 is provided on the outer surface of this mounting portion 6. A first cap 15 is detachably attached to the first opening 5, and the first opening 5 is opened and closed by this first cap 15.

[0035] As shown in Figures 4 and 5, the first cap 15 consists of a cylindrical body portion 16 and a disc-shaped lid portion 18 that closes one end of the body portion 16. The inner surface of the body portion 16 is provided with a female thread 17 that matches the male thread 7 of the mounting portion 6 of the first opening 5. By screwing the female thread 17 of the body portion 16 onto the male thread 7 of the mounting portion 6 of the first opening 5 and tightening it with a predetermined torque, the first opening 5 is closed, and the storage chamber 3 inside the water tank body 2 can be sealed.

[0036] A circular second opening 9, smaller in diameter than the first opening 5 which penetrates both the inside and outside, is provided at the center of the upper surface of the second protrusion 8, and a pressure pump 25, described later, is attached to this second opening 9. Compressed air is supplied into the containment chamber 3 of the water tank body 2 by the operation of the pressure pump 25.

[0037] A cylindrical mounting portion 10 that protrudes upward is integrally provided around the second opening 9, and a male screw 11 is provided on the outer surface of this mounting portion 10. When no deep-sea organisms 46 are contained in the containment chamber 3, a second cap 21 for opening and closing the second opening 9 is detachably attached to the second opening 9.

[0038] As shown in Figures 6 and 7, the second cap 21, like the first cap 15, is composed of a cylindrical body portion 22 and a disc-shaped lid portion 24 that closes one end of the body portion 22. The inner surface of the body portion 22 is provided with a female thread 23 that matches the male thread 11 of the mounting portion 10 of the second opening 9. By screwing the female thread 23 of the body portion 22 onto the male thread 11 of the mounting portion 10 of the second opening 9 and tightening it with a predetermined torque, the second opening 9 is closed, and the storage chamber 3 inside the container body 2 can be sealed.

[0039] The container body 2 is formed in a box shape using thermoplastic engineering plastic, which has excellent impact resistance and heat resistance. In this embodiment, polycarbonate is used as the material and formed into a box shape that is small enough to be carried by hand using molding methods such as injection molding.

[0040] Polycarbonate is a material that has heat and cold resistance from -40°C to 120°C, as well as a compressive strength of approximately 60 to 90 MPa. Therefore, by constructing the container body 2 using this material, it becomes possible to pressurize the inside of the container body 2's containment chamber 3 to a level that can alleviate the symptoms of decompression sickness in deep-sea organisms 46.

[0041] The first cap 15 and the second cap 21 are formed from polycarbonate having the same properties as the container body 2.

[0042] When housing deep-sea organisms 46 in the storage chamber 3 of the container body 2, the second cap 21 is removed from the second opening 9 to open the second opening 9, a pressure pump 25 is attached to the second opening 9, a predetermined amount of seawater is filled into the storage chamber 3 of the container body 2 through the first opening 5, and the first cap 15 is attached to the first opening 5 to close the first opening 5.

[0043] In this embodiment, a commercially available "washable tank (manufactured by Iwatani Material Co., Ltd.)" is used for the container body 2.

[0044] The pressurizing pump 25 is manually operated and, as shown in Figures 1 and 3, comprises a pump body 26 detachably attached to the second port 9 of the container body 2, a suction pipe 40 attached to the lower end of the pump body 26, a discharge pipe 41 attached to the side of the pump body 26 and communicating with the suction pipe 40, and an on / off valve 42 for opening and closing the discharge pipe 41.

[0045] The pump body 26 is composed of a casing 28 which is cylindrical with its upper and lower ends closed and has an insertion hole 29 that penetrates vertically in the center of its upper surface; a body 27 which consists of a branch block 30 attached to the lower end of the casing 28 and a mounting cap 37 provided on the lower end of the branch block 30; a bellows-shaped cylindrical bellows 35 which is retractably provided inside the casing 28 of the body 27; and a cylindrical pressing part 36 which has its upper end closed and is provided inside the insertion hole 29 of the casing 28 so as to be movable in the axial direction of the casing 28.

[0046] The mounting cap 37 is annular in shape and has a female thread 38 on its inner surface that matches the male thread 7 of the mounting portion 6 of the first port 5. The pump body 26 is attached to the first port 5 by screwing this female thread 38 onto the male thread 7 of the mounting portion 6 of the first port 5 and tightening it with a predetermined torque.

[0047] The bellows 35 has an upper end opening connected to the lower end opening of the pressing portion 36, and its lower end opening connected to the upper end of the branching block 30. This creates a sealed space inside the bellows 35. An air intake port (not shown) is provided at the upper end of the bellows 35, and an air exhaust port (not shown) is provided at the lower end, with the exhaust port connected to the upper end of the air passage 32 of the branching block 30.

[0048] The branching block 30 is provided with an L-shaped liquid flow passage 31 that penetrates the upper surface of the mounting cap 37 and extends to a predetermined position above the branching block 30, and further penetrates the side of the branching block 30 from that position. The upper end of a suction pipe 40, which draws in the liquid filled inside the container body 2, is connected to the lower end of the liquid flow passage 31, and one end of a discharge pipe 41, which discharges the liquid, is connected to the upper end of the liquid flow passage 31. Note that the liquid flow passage 31, suction pipe 40, and discharge pipe 41 are not used when transporting deep-sea organisms 46.

[0049] The branching block 30 is provided with an air passage 32 that penetrates vertically. The upper end of this air passage 32 is connected to the exhaust port at the lower end of the bellows 35, and the lower end penetrates the upper surface of the mounting cap 37 and opens into the container body 2. Compressed air is supplied to the inside of the container body 2 through the air passage 32.

[0050] An air vent 33 is provided at a predetermined position on the side of the branching block 30, communicating with the air passage 32, and air from inside the containment chamber 3 of the container body 2 is released to the outside through this air vent 33. A seal 34 is detachably attached to the air vent 33, and the air vent 33 can be opened by removing the seal 34.

[0051] An on / off valve (not shown) is provided at the upper end opening of the air passage 32. When the bellows 35 is compressed by pressing the pressing part 36 by hand, the air pressure causes the valve to "open," opening the upper end opening of the air passage 32 and allowing air to be supplied to the containment chamber 3 of the container body 2 through the air passage 32. When the hand is released from the pressing part 36 and the bellows 35 returns to its extended state due to the restoring force, the space inside the bellows 35 becomes negative pressure, causing it to "close," closing the upper end opening of the air passage 32 and stopping the supply of air to the container body 2 through the air passage 32, while also preventing the supplied air from escaping from inside the container body 2. By repeatedly pressing down on the pressing part 36 and releasing it, the internal pressure of the containment chamber 3 of the container body 2 can be gradually increased.

[0052] In this embodiment, a "pressurized kerosene pump (manufactured by Koshin Co., Ltd.)" is used as the manual pressure pump 25.

[0053] Next, the procedure for using the pressurized water tank 1 of this embodiment, configured as described above, will be explained.

[0054] First, as shown in Figure 8, the first cap 15 is removed from the first opening 5 of the container body 2, and the second cap 21 is removed from the second opening 9, leaving the first opening 5 and the second opening 9 open. Then, a predetermined amount of seawater 45 is filled into the storage chamber 3 of the container body 2 through the first opening 5 by appropriate means.

[0055] Next, as shown in Figures 1 and 9, the pressure pump 25 is attached to the second port 9. Specifically, the suction pipe 40 of the pressure pump 25 is inserted from the second port 9 into the housing chamber 3 of the container body 2, and the female thread 38 of the mounting cap 37 is screwed onto the male thread 11 of the mounting part 10 of the second port 9 and tightened to a predetermined torque to attach the pressure pump 25 to the second port 9. In this case, a packing (not shown) is interposed between the second port 9 and the mounting cap 37 to prevent leakage of air and seawater from between them.

[0056] Next, as shown in Figure 10, the captured deep-sea organism 46 is placed into the containment chamber 3 of the tank body 2 through the first opening 5. The first cap 15 is then attached to the first opening 5 by screwing the female thread 17 of the main body 16 of the first cap 15 onto the male thread 7 of the mounting part 6 of the first opening 5 and tightening it with a predetermined torque, thereby sealing the first opening 5. In this case, a packing (not shown) is interposed between the first opening 5 and the first cap 15 to prevent air and seawater from leaking between them. Immediately after being placed in the containment chamber 3, the swim bladder of the deep-sea organism 46 expands due to the rapid change in water pressure, causing it to float belly up (decompression sickness).

[0057] Next, as shown in Figure 11, the pressing part 36 of the pressurizing pump is repeatedly pressed down and released by hand to supply compressed air into the containment chamber 3 of the container body 2, gradually increasing the internal pressure in the containment chamber 3. In this case, it is confirmed in advance that the on / off valve 42 of the discharge pipe 41 is closed and the air vent hole 33 is closed with a seal 34 to prevent air leakage through them when the pressing part 36 is pressed down.

[0058] In this way, the internal pressure of the containment chamber 3 of the container body 2 is gradually increased, pressurizing the containment chamber 3 to a level that can alleviate the symptoms of decompression sickness in the deep-sea organisms 46. As a result, the symptoms of decompression sickness in the deep-sea organisms 46 contained in the containment chamber 3 are gradually alleviated, and they recover from floating with their bellies facing upwards to a normal state.

[0059] Then, after confirming that the deep-sea organisms 46 have recovered from decompression sickness within the containment chamber 3 of the container body 2, the container body 2 is transported to a facility such as an aquarium with the pressurizing pump 25 still attached, and after the prescribed procedures are performed, the organisms are placed in a tank at the facility.

[0060] In the simplified pressurized container 1 of this embodiment, configured as described above, a commercially available polycarbonate tank is used as the container body 2, and a commercially available pressurized kerosene pump is used as the pressurized pump 25, resulting in an inexpensive and simple structure. Therefore, there is no need to prepare complex and expensive equipment to alleviate the symptoms of decompression sickness in captured deep-sea organisms 46, and the cost of alleviating the symptoms of decompression sickness in deep-sea organisms 46 can be significantly reduced.

[0061] Furthermore, the container body 2 is made of thermoplastic engineering plastic (polycarbonate) with excellent impact resistance and heat resistance, and has heat resistance from -40°C to 120°C, cold resistance, and a compressive strength of approximately 60 to 90 MPa. Therefore, the container body 2 can be pressurized to a level that alleviates the symptoms of decompression sickness in deep-sea organisms 46. Consequently, deep-sea organisms 46 that float belly-up due to the rapid change in water pressure and whose swim bladder expands can be quickly restored to their original state and become healthy, thereby increasing the survival rate of the captured deep-sea organisms 46.

[0062] Furthermore, the container body 2 is designed to be small and light enough to be carried by hand, making it easy to move. Therefore, the simple pressurized container 1 can be easily brought onto a ship or other vessel and used to alleviate the symptoms of decompression sickness in captured deep-sea organisms 46. This eliminates the need to install complex, large, and expensive equipment on board the ship or other vessel, and allows for the alleviation of decompression sickness symptoms in deep-sea organisms 46 on board without incurring significant costs.

[0063] Furthermore, since the deep-sea organisms 46 can be contained within the containment chamber 3 of the simple pressurized container 1, the simple pressurized container 1 can be moved from a ship to a truck or the like, and then transported by truck to facilities such as aquariums, aquarium shops, and recreational fishing boats, there is no need to prepare large and expensive equipment on the truck to increase the survival rate of the deep-sea organisms 46, and the transportation costs of the deep-sea organisms 46 can be significantly reduced.

[0064] Furthermore, even when releasing the organisms from a ship or other vessel, it is possible to reduce the symptoms of decompression sickness in the captured deep-sea organisms 46 by using a pressurized tank 1 on board the ship or other vessel, without the need for expensive or cumbersome equipment. This allows for easy release into the sea with a higher survival rate.

[0065] In this embodiment, a "washable tank" manufactured by Iwatani Material Co., Ltd. was used for the container body 2, and a "pressurized kerosene pump" manufactured by Koshin Co., Ltd. was used for the pressure pump 25. However, the invention is not limited to these, and various well-known tanks and various well-known manual pumps with similar characteristics may be used. In that case, the same effects will be achieved. Also, a well-known electric pressure pump may be used instead of the manual pressure pump 25.

[0066] In this embodiment, the suction pipe 40 and discharge pipe 41 of the pressurizing pump 25 were left attached, but they may be removed before the deep-sea organism 46 is recovered from decompression sickness. In that case, the connection part of the discharge pipe 41 should be sealed tightly.

[0067] Furthermore, the inventors of this invention slowly lifted deep-sea organisms 46 caught by fishing and placed them in the containment chamber 3 of the simple pressurized container 1 of this embodiment. When the containment chamber 3 was pressurized to a pressure similar to that near the surface (0.3-0.4 MPa), the symptoms of decompression sickness in the deep-sea organisms 46 were reduced, and the deep-sea organisms 46 were able to survive.

[0068] This revealed that, in the case of capture by fishing, the survival rate of the deep-sea organisms 46 can be increased by "slowly lifting" the captured deep-sea organisms 46 and "applying pressure near the surface in the simple container 1". [Explanation of symbols]
