Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport box apparatus for live fish or the like which can be delivered to small restaurants or izakayas or the like while keeping the live fish or the like in the water in the transport box.

[0002]

2. Description of the Related Art Conventionally, when transporting live fish and shellfish such as live fish, the amount of dissolved oxygen in the water in the fish tank should be ensured while the temperature of the water and the amount of dissolved ammonia should be maintained. It must be kept below a predetermined value. In the management of water in the fish tank, for example, for removing ammonia, there is a device provided with a biological filtration mechanism using ammonia-degrading bacteria, but the device itself is large in size in order to stably maintain the activity of ammonia-degrading bacteria. Therefore, there is a disadvantage that the transportation cost and the production cost are likely to be relatively high. Also, in a fish tank that transports live fish, when air is blown into the water to supply oxygen, the air blown into the water becomes air bubbles and floats on the surface of the water, causing protein components in the water to flow. If the amount is large, a large amount of air bubbles are formed, and the air bubbles float on the water surface. These bubbles contain a protein component, which is decomposed into ammonia and dissolved in water to increase the amount of ammonia. Therefore, if the air bubbles floating on the water surface are collected early and separated from the water, the amount of ammonia dissolved in the water can be reduced, and the live state of the live fish can be maintained for a long time.

[0005] Therefore, as shown in FIG. 5, a board 160 having a recess 120 extending vertically from the bottom and having a plurality of slits 140 formed on the surface thereof is fitted to the tank wall 110 of the fish tank 100. An air supply body 190 having a fine hole which is communicated with the air pipe 180 and injects air is arranged on the bottom side of the recess 120 to inject compressed air.
The compressed air rising in the inside of each slit 14 of the board 160
Oxygen is supplied to the water W by being ejected from 0 along with the bubble K. In addition, in order to take in the air bubbles K floating and floating on the water surface, a bubble opening 200 is opened in the vicinity of the water surface of the tank wall, and bubbles are installed from the tank 240 for the bubbles installed vertically through the groove 220 from the bubble opening 200. A container for transporting live fish and the like for recovering fish has been proposed in JP-A-5-176657.

[0004]

However, in the above-mentioned transport container, since the bubbles K floating on the water surface naturally flow into the bubble collecting port 200 provided near the water surface of the tank wall, the generated bubbles are generated. The efficiency of recovering K is low, bubbles on the water surface diffuse and dissolve into the water, and the amount of ammonia in the water increases, making it impossible to maintain the live state of seafood such as live fish for a long time. . Also, a concave portion 120 for ejecting air, a groove portion 220 for bubble collection,
Since the tank 240 and the like are provided inside the tank wall for foaming, the configurations of the air supply unit and the bubble treatment unit are complicated, and the production cost is likely to be relatively high. In addition, a board for oxygen supply is provided in the water of the tank, and the size of the transport box is enlarged to secure an effective volume for transported fish.As a result, small dishes can be prepared with live fish etc. in the transport box. There is a problem that it is not practical for home delivery to izakaya, izakaya, and small-lot transportation.

The present invention has been made in view of the above-mentioned conventional problems, and one object of the present invention is to immediately capture air bubbles sent into water for oxygen supply on the water surface and to cover the entire water surface. It is possible to keep the living state of live fish etc. for a long time by keeping the ammonia concentration due to decomposition of the protein component in the bubble so that it does not spread, and it is not necessary to provide large facilities and complicated mechanisms etc. It is another object of the present invention to provide a transport box device for live fish and the like, which can surely achieve a reduction in the size, weight, and manufacturing cost of the transport box. Further, another object of the present invention is to make it possible to deliver to a small restaurant or izakaya, etc. without a fish tank facility with live fish and the like in a transport box by miniaturizing the transport box, or to keep the same as it is. Therefore, an object of the present invention is to provide a transport box device for live fish and the like which can be practically used for transporting small live fish.

[0006]

In order to solve the above-mentioned problems, the present invention provides a transport box 12 storing water W for keeping alive fish alive, and installed in the transport box 12;
Air supply means 14 for supplying air for oxygen supply,
Bubbles K due to the supplied air form the surface 16 of the stored water.

BEST MODE FOR CARRYING OUT THE INVENTION A transport box apparatus for live fish and the like according to the present invention comprises a transport box storing water for keeping alive fish alive, and an air for supplying oxygen into water in the transport box. Air supply means for sending air, and air bubble capturing means for capturing air bubbles at a part of the water surface without the air bubbles caused by the supplied air spreading over the entire water surface of the stored water. The transport box may be made of a heat-insulating material so as not to be easily affected by the outside temperature, and may be any as long as it can form a watertight chamber capable of holding water for accommodating live fish. Moreover, you may form in the small box body with a lid which is easy to carry by the seller of live fish etc. Further, the transport box may be formed in a box of any other shape such as a cylinder, a polygon, and the like in addition to a cube and a rectangular parallelepiped. In addition, the transport box may be configured to be used as a large fish tank for transporting live fish and the like over long distances.

[0013] The air supply means includes an air supply device connected to the air pump via an air supply pipe. The air supply device may be a perforated pipe for ejecting air supplied from an air pump, or any other supply mechanism. Preferably, a rod-shaped ceramic body, a concrete block body or the like in which fine holes for ejecting air are opened are preferable. By arranging this rod-shaped ceramic body etc. at a position near one side wall of the inner bottom surface of the shipping box, the air ejected from the fine holes rises in the water near the one side wall inside the shipping box, so that live fish etc. are needed. Supply oxygen.

The bubble capturing means has a capturing portion for capturing bubbles at a part of the water surface. This trapping part sucks and eliminates air bubbles floating on the water surface, thereby capturing air bubbles including protein components so as not to spread over the entire water surface, and finally keeping the ammonia concentration in the water low. The air bubbles may be naturally discharged to the outside by the pressure of the supplied air, or may be a suction elimination mechanism for forcibly sucking and excluding the air to the outside. This makes it possible to maintain a live state of a live fish or the like for a long time.

Further, the bubble capturing means includes a closing portion for partitioning a floating portion of the bubble by the supply air from the space inside the other transport box in a closed manner, and the air bubble captured in the close portion to the outside from the transport box. An exhaust unit for exhausting air may be provided. The closing portion may be a closed compartment that has a closed space that is open on the lower surface side and traps air bubbles therein, and that is installed in a transport box and is not bulky. In this closed compartment, the periphery of the lower end opening is submerged in water, and the closed space inside is partitioned from the space inside the shipping box. Since the bubble capturing means only captures air bubbles floating on a part of the water surface, the bubble capturing means can be formed in a small size with a simple structure, and the size and cost of the shipping box can be reduced. Therefore, the delivery box can be delivered to a small restaurant or izakaya with no fish tank facilities by utilizing the live fish and the like, and the fish can be kept as it is. The exhaust unit may be an exhaust pipe that communicates with a closed space in the closed compartment and extends outside the shipping box.
Therefore, the closing portion can reliably trap air bubbles in a part of the water surface with a simple structure. Further, the closing portion and the exhaust portion cooperate to appropriately exhaust the air pressure in the closed space, so that the air bubbles secured on the water surface can be properly processed. Therefore, the air bubbles trapped in the closed portion do not flow to the compartment inside the box outside the closed portion, and it is possible to reliably prevent the bubbles from diffusing on the water surface outside the closed portion.

Further, air pressure adjusting means for adjusting the air pressure in the closing portion may be provided. As the air pressure adjusting means, an adjusting valve connected to an extended end of the exhaust part is preferable. Further, an adjustment valve may be directly communicated with the upper surface side of the closing portion, and the exhaust portion may be extended from the adjustment valve. The air bubbles supplied by the air supply means are trapped in the closed part on the water surface, and the adjusting valve is adjusted so that the air bubbles staying in the closed part do not bypass the lower end of the closed part and escape to the outside of the closed part. To exhaust air bubbles from the exhaust unit. That is, when the amount of air supplied from the air supply means is large, the regulating valve is opened to the fully open state, and the amount of bubbles exhausted from the inside of the closed portion is increased to prevent the trapped bubbles from escaping. Conversely, when the amount of supplied air is small, the regulating valve is throttled to adjust the amount of air bubbles exhausted from the inside of the closing portion. Therefore, it is possible to capture and remove the optimal amount of bubbles corresponding to the supply amount of air, and it is possible to exhaust the bubbles taken in the closure without flowing to the water outside the closure. .

Further, the closing portion may be a frame that is removably installed in the transport box in a lid-like manner so as to cover a floating portion of air bubbles caused by supply air. The frame is preferably a box-shaped frame whose lower surface is open. Moreover, you may attach and detachably mount to a transport box. The structure of the frame is simple, the size and weight of the transport box itself are reduced, and repair, replacement, cleaning, etc. of the frame can be easily performed. Moreover, you may be arrange | positioned fixedly in a shipping box.

Further, the exhaust portion may include an exhaust hose that connects the frame to the outside of the shipping box. As the exhaust hose, a hose made of a soft synthetic resin, rubber, or the like is preferable. In the narrow space inside the shipping box, the frame and the outside of the shipping box can be freely communicated with each other. The exhaust portion is not limited to a flexible exhaust hose, but may be fixedly wired and held in a transport box with a hose body made of a hard synthetic resin, corrosion-resistant metal, or the like.

Further, a natural recirculation mechanism having a filter for filtering water in the transport box, and a guide portion for directing an outlet of water passing through the filter to a rising path of bubbles by the air supply means. May be provided. The filter body is
A mesh bag filled with a particulate filter material such as activated carbon or ceramic is preferred. Further, the filter may be a filter sheet or filter paper fiber reinforced with a metal wire or the like. The guide portion extends from the filter body side for filtering water in the transport box to, for example, a rising path side of the bubble via a pipe or the like, so that an end thereof faces the rising path of the bubble as a water outlet. They may be arranged. The natural reflux mechanism applies a suction negative pressure to the outlet of the guide portion by the upward flow of bubbles in the upward path to naturally return the water in the transport box, and to flow the water through the filter to purify the water. When the suction negative pressure acting on the outlet is weak, a part of the compressed air on the air supply means side may be blown into the guide portion to assist the reflux.

The bubbles K trapped in the frame body 46 due to the increase in the air pressure are sequentially exhausted via the exhaust hose 58 and the adjustment valve 62. When the amount of air supplied from the air supply device 32 is large, the control valve 62 is opened to the fully open state to increase the amount of bubbles exhausted from the inside of the closing portion 42,
When the amount of supplied air is small, the control valve 62 is throttled to adjust the amount of air bubbles exhausted from the inside of the closing portion 42. Therefore, the bubbles K staying inside the closing portion 42 do not escape to the outside of the closing portion 42, and the required bubbles K are exhausted to the outside,
It is possible to capture an optimal amount of bubbles K corresponding to the amount of air supplied by the air supply device 32 and remove the bubbles to the outside.

As described above, since the trapping process is performed so that the bubbles K generated by supplying oxygen into the water W do not spread over the entire surface of the water, the increase in the ammonia concentration in the water due to the bubbles K can be suppressed. The living state of the live fish F and the like in the transport box 12 can be maintained for a long time. In addition, there is no need to provide a dedicated large-scale facility or a complicated mechanism for reducing the amount of ammonia in the water W, so that the size and weight of the shipping box 12 and the manufacturing cost can be reduced.

Further, in the water W in the transport box 12, the rising water flow of the bubble K flows into the outlet 66 on the upper end side of the reflux pipe 72 arranged in the rising path R of the bubble K rising from the air supply device 32. The water W sucked by the filter cylinder 74 at the lower end of the U-shaped return pipe 72 flows upward through the return pipe 72 and flows out from the outlet 66. The filter body 64 on the inner bottom surface side is injected into the water W in the transport box 12,
The U-shaped reflux pipe 72, the outlet 66, and the like form a natural reflux path. Since the water W in the transport box 12 is naturally returned and filtered through the natural return path through the filter 64, a large amount of power is not required for maintaining a live state of the live fish or the like, and the power is not required. Expenses can be saved. In addition, since the living state of the live fish and the like can be maintained for a long time with a small power, the delivery of the live fish and the like using the transport box 12 can also be specifically performed.

As described above, the transport box apparatus for live fish and the like according to the present invention captures air bubbles of oxygen-supplied air in the water in the transport box on a part of the water surface and exhausts the water to the outside. In addition to suppressing the increase of ammonia concentration in the water, the live state of live fish etc. in the transport box can be maintained for a long time, and dedicated large-scale equipment and complicated equipment for reducing the amount of ammonia in the water There is no need to provide a special mechanism,
The miniaturization and weight reduction of the shipping box and the reduction of the manufacturing cost can be surely achieved. In addition, by reducing the size of the transport box, it becomes possible to deliver to a small restaurant, izakaya, or the like while delivering live fish or the like in the transport box, or to hold it as it is.

As described above, the transport box apparatus for live fish and the like according to the present invention includes a transport box storing water for keeping the live state of the live fish, and an oxygen supply in the water in the transport box. Air supply means for feeding air for air supply, and bubble capturing means for capturing air bubbles at a part of the water surface without causing air bubbles due to the supplied air to spread over the entire water surface of the stored water. By supplying oxygen to the water in the transport box and trapping the air bubbles generated, so that it does not spread over the entire surface of the water, the protein components in the bubbles are decomposed into ammonia and dissolved into the water, Ammonia concentration does not increase, the live state of live fish etc. in the transport box can be maintained for a long time, and large-sized biological filtration equipment such as a biological filtration device to reduce the amount of ammonia in the storage water Equipment and complex It is not necessary to provide a structure, miniaturization of the shipping container, weight reduction, it is possible to reliably achieve low manufacturing cost. In particular, it is possible to deliver the live fish or the like in the transport box to a small restaurant, izakaya, or the like without a fish tank facility due to the downsizing of the transport box, or to keep it as it is, and to transport the small-mouth live fish, and It is possible to cope with small live fish consumption.

Further, the bubble capturing means includes a closing portion for partitioning a floating portion of the bubble by the supply air from the space inside the other transport box in a closed manner, and the air bubble captured in the close portion to the outside from the transport box. By providing an exhaust unit for exhausting air, air bubbles floating in the water are reliably captured in the closed part and exhausted to the outside so that the air bubbles stay in the closed part, increase the pressure and escape to the outside of the closed part. Without flowing, it is possible to reliably prevent diffusion on the water surface outside the closed part.

Further, by providing air pressure adjusting means for adjusting the air pressure in the closed portion, the air pressure in the closed portion does not allow the staying air bubbles to flow out of the closed portion, and removes the required air bubbles. By evacuating to the outside, it is possible to perform an optimal bubble capture and removal action corresponding to the amount of air supplied by the air supply means, and to effectively eliminate bubbles taken into the closed part by air pressure. Is possible.

Further, the closing portion is a frame body which is detachably mounted in the transport box so as to cover the floating portion of the air bubble by the supply air in a lid-like manner, so that the air bubble floating on the water surface in the transport box is raised. Since the frame has a simple configuration in which a frame is erected in a cover-like shape at a portion, the configuration of the bubble capturing means is extremely simple, and the manufacturing and material costs are low, and the frame is removable. Thus, repair, replacement, cleaning, etc. can be easily performed, and the size and weight of the entire apparatus can be effectively reduced.

Further, the exhaust portion includes an exhaust hose communicating the frame with the outside of the shipping box, so that the other end of the exhaust hose having one end communicating with the frame installed in a closed state in the shipping box. The side can be easily communicated with the outside of the shipping box by using the narrow space such as the frame and the top lid, so that the bubbles trapped in the frame are eliminated and the bubbles rise to the frame while eliminating the bubble gas to the outside. The generated bubbles can be continuously captured and discharged to suppress an increase in the amount of ammonia in the water.

Further, a natural reflux mechanism having a filter for filtering water in the transport box, and a guide for allowing an outlet of water passing through the filter to face a rising path of bubbles by the air supply means. Since the outlet is arranged on the rising path of the bubble by the air supply means in the water of the transport box, the return path of the underwater, the guide, and the rising path is formed, thereby utilizing the rising water flow. As a result, the water in the transport box can be filtered by allowing the water in the transport box to naturally return to pass through the filter, so that a large amount of power is not required for maintaining the live state of live fish and the like, and power costs can be saved. Can be.
In addition, since live state of live fish and the like can be maintained for a long time with a small power, delivery of live fish and the like using a transport box can be specifically performed.
