Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water container for raw seafood, and more particularly to a novel container structure suitable for transporting appreciation fish in a water tank.

[0002]

[Prior art]

 Conventionally, there is a case where the fish to be watched are housed in an aquarium, and in this case, in order to give oxygen to the fish to watch inside, at least the opening formed in the upper part of the fish tank is opened. There is a need. In addition, in order to positively supply oxygen, air may be forced into the water in the water tank by an air pump or the like.

On the other hand, when the ornamental fish is transferred, particularly when it is transported to a remote place, water and the ornamental fish are stored in a resin container or bag different from the original water tank, and oxygen is further stored inside. It is filled and sealed to prevent appreciating fish from dying or weakening due to lack of oxygen even during long-term transportation.

[0004]

[Problems to be solved by the device]

 However, in the above conventional water tank, it is difficult to transfer water or fish while it is stored inside because the upper opening is open. The parts were either completely closed or the fish were once moved to a closed container as described above.

In the above-mentioned resin containers and bags, since oxygen is filled in the interior, it is possible to transfer without problems for a short time of about a few days, but in the case of long-distance transportation, oxygen deficiency occurs. Cause fish death and weakness. For this reason, in order to enable long-distance transportation by increasing the amount of oxygen filled inside, it is necessary to secure a sufficient space for storing oxygen, which inevitably results in the storage volume of fish. However, there is a problem that the volume of the whole container increases conversely as the volume decreases.

Therefore, the present invention solves the above-mentioned problems, and the problem is that raw fish can be transported for a long time without being filled with oxygen while the raw fish are stored, and water is not spilled. It is to realize a water container for raw seafood.

[0007]

[Means for Solving the Problems]

 Means for solving the above problems is to provide a water container for raw seafood having an opening at an upper part, which is formed so as to be able to store water, and is provided with a cap member attached to the opening. Between the cap member and the opening, a closing plate having a shape capable of closing the opening and having flexibility and oxygen permeability is sandwiched, and a large number of pieces are provided on the surface of the cap member. The small opening is formed so that the surface has rigidity to withstand the water pressure of the contained water.

Here, it is preferable that a cutout for allowing oxygen to permeate is formed in the closing plate.

In this case, it is preferable that the notch be formed at a position other than the peripheral edge of the closing plate sandwiched between the peripheral edge of the opening and the cap member.

Further, at least two of the closing plates are sandwiched between the opening portion and the cap member so as to be sandwiched, and the notches of the stacked closing plates are placed in a plane position substantially overlapping each other. It is preferable that the stretching directions are different from each other.

Further, the first magnetic body is arranged on the outer surface of the container, and the second magnetic body is fixed to the solid matter housed therein, and at least the first magnetic body and the second magnetic body are provided. It is preferable that either of them be magnetized and mutually adsorbed.

[0012]

[Action]

 According to claim 1, by inserting a closing plate having flexibility and oxygen permeability between the opening and the cap member, the opening can be sealed by the flexibility of the closing plate, and Since the cap member has a small opening, it is possible to secure the circulation of oxygen inside and outside the container through the small opening through the small opening, while the cap member can withstand the internal water pressure. Since it is a container, even if the container falls or reverses, the closing plate does not deform outward and the water inside does not overflow.

According to the second aspect, by providing the notch in the closing plate, oxygen permeability can be easily imparted, and since the notch is formed of a flexible material, water pressure or the like can be prevented. If stress is not applied, it will not open greatly, and even if water pressure is applied, outward deformation is suppressed by the cap member, so that water leakage can be prevented.

According to the third aspect of the present invention, the notch is formed at a position other than the peripheral edge of the closing plate sandwiched between the peripheral edge of the opening and the cap member. Since the stress on the groove can be reduced, the occurrence of water leakage due to the deformation of the cut portion can be prevented.

According to the fifth aspect, at least two closing plates are sandwiched between the opening and the cap member, and the notches of the stacked closing plates are arranged in planes substantially overlapping each other in the extending direction. Since the caps are made different from each other, even if stress is applied in the rotational direction when the cap member is attached, the stress can be relieved by sliding the closing plates, and the cuts are arranged in different directions. Therefore, it is possible to secure the oxygen permeability while suppressing the opening of the cut portion.

According to the fourth or sixth aspect, since the solid matter in the container is fixed by the magnetic force, the solid matter may be moved and damaged during transportation, or the surrounding raw seafood may be damaged. Can be prevented.

[0017]

[Embodiment] Next, an embodiment of the water container for raw seafood according to the present invention will be described with reference to the accompanying drawings. This embodiment can be used as an aquarium for ornamental fish, and at the same time, it can be sufficiently used for long-distance transportation with raw fish stored as it is.

FIG. 1 is an enlarged perspective view showing the upper part of the present embodiment in an enlarged manner, and FIG. 2 is a perspective view showing the overall configuration of the present embodiment. In this embodiment, as shown in FIG. 2, a container body 10 having a disc shape as a whole and a cap member 20 screwed onto the upper portion of the container body 10 are provided. A support 11 is formed on the bottom of the container body 10. On the other hand, as shown in FIG. 1, a male screw portion 12 is formed on the upper portion of the container body 10. An opening 13 is formed at the upper end of the male screw portion 12, and an opening edge portion 14 formed substantially flat is formed around the opening 13. The entire container body 10 is formed by blow molding, and is integrally formed of a transparent resin such as polyethylene terephthalate (PET).

The cap member 20 is formed of a hard resin such as styrene resin or acrylic resin molded by injection molding, for example. A large number of small openings 21, 22, 23 are formed on the upper surface 20a of the cap member 20. The small openings 21, 22, 23 are formed substantially uniformly on the upper surface 20a of the cap member 20 so as to ensure air circulation inside and outside the cap member 20. A female screw portion (not shown) formed so as to be screwed into the male screw portion 12 of the container body 10 is formed on the inner peripheral surface of the cap member 20.

Two contact closing plates 31, 32 are housed between the opening edge portion 14 and the cap member 20. Notches 31a and 32a are formed in the centers of the close contact plates 31 and 32, respectively, and the notches 31a and 32a are inserted so that the directions thereof do not face the same direction. The tightly closed closure plates 31, 32, which are superposed on each other, are placed on the opening edge portion 14 and fixed by screwing the cap member 20 from above.

The close contact plates 31 and 32 are formed of a flexible soft resin, and particularly preferably formed of a resin having elasticity and oxygen permeability such as foamed polyethylene. Further, for example, when a close contact plate having a diameter of 54 mm and a thickness of 0.5 mm is used, the length of the cut is preferably about 10 to 20 mm. If the cut is too long, water leakage is likely to occur, and if the cut is too short, the oxygen permeability is lowered. Therefore, the length of the cut is preferably appropriately changed depending on the diameter and the degree of rigidity of the contact closing plate.

In this embodiment thus formed, the outside air is supplied into the container body 10 from the small openings 21, 22, 23 of the cap member 20 through the close contact plates 31 and 32. As shown in FIG. 2, even if water is put in the container body 10 and fishes such as fish, shrimp, and shellfish are bred, oxygen deficiency is less likely to occur, and the cap member 20 is screwed firmly. By placing the contact closure plates 31 and 32 to close the opening 13 of the container body 20, water leakage does not occur.

Here, when the seafood is stored inside for a long time, oxygen in the water is consumed to become carbon dioxide, which dissolves in the water. When the oxygen concentration decreases, oxygen in the air existing inside the container body 10 dissolves in the water, is consumed in the water, and becomes carbon dioxide and further dissolves in the water. In this way, when the container body 10 is sealed, the oxygen in the container body 10 is gradually reduced, and the inside of the container body 10 is depressurized.

In this embodiment, when oxygen in the container body 10 is consumed and the pressure is reduced, air is introduced by opening the notches 31a and 32a of the flexible close contact closing plates 31 and 32 to the inside, and New oxygen is supplied into the main body 10. However, even if the pressure inside the container body 10 is not greatly reduced, a certain amount of air is circulated through the cuts 31a and 32a. When a material having oxygen permeability such as foamed polyethylene is used, oxygen enters the container body 10 having a low oxygen partial pressure through the close contact plates 31 and 32 themselves.

On the other hand, when pressure is applied to the inner surface side of the close contact closing plate 32 of the opening 13 due to the container falling or being turned upside down, the cuts 31a and 32a of the close contact closing plates 31 and 32 are made. Also tries to open outward due to pressure, but in this case, the formation directions of the notches 31a and 32a of the two close contact plates 31, 32 are different and the cap member 20 is attached to the outside. The upper surface 20a suppresses upward deformation of the close contact closing plates 31, 32, so that the water inside does not overflow to the outside.

The small openings 21, 22, 23 of the cap member 20 prevent the outward deformation of the close contact plates 31, 32, particularly the deformation of the portions where the cuts 31a, 32a are formed. It is formed in consideration of the opening diameter, the formation distribution, the number, etc. according to the material, diameter, and thickness of the. When the total area of the small openings increases, the rigidity of the upper surface 20a of the cap member 20 becomes weaker, and it becomes impossible to suppress the outward deformation of the close contact plates 31 and 32. If the amount is reduced, the supply of oxygen into the container body 10 is hindered.

FIG. 3 is a vertical sectional view showing the overall structure of this embodiment. In this embodiment, a concave portion 11a is formed on the bottom surface side of the support 11, and an iron plate, a magnetic body 15 such as a permanent magnet is arranged in the concave portion 11a, and a bulb of aquatic plants contained in the container body 10 is formed. It is arranged to face a magnetic body 17 attached to a plant body 16 such as a tuber. At least one of the magnetic body 15 and the magnetic body 17 is magnetized and is attracted by a magnetic force with the wall surface of the container body 10 sandwiched therebetween.

With such a structure, the plant body 16 can be held on the bottom surface side by a predetermined magnetic force, so that the plant body does not move even if the container is tilted or turned upside down during transportation. The risk of damaging itself or the seafood contained therein is reduced. Further, by moving the magnetic body 17, it is possible to easily move the plant body 16 in the container. In addition, when the plant body 16 is transplanted from the container that has been transported to another aquarium, etc. By slowly moving the placed magnetic body 17 toward the opening 13, the plant 16 can be easily taken out from the opening 13.

FIG. 4 shows various shapes of the contact closing plates 31 and 32. The notches 31a and 32a formed on the close contact plate can be formed in various shapes such as a straight line, a curved line, and a cross, as shown in FIGS. 4 (a) to 4 (d). However, it is most preferable to form a linear cut to prevent the opening of the cut portion. Further, as shown in FIG. 4 (e), the notch forming position is not limited to the central part, and may be formed at the peripheral part of the close contact closing plate. However, since the cap member 20 is screwed in and the tight closing plate is sandwiched between the cap member 20 and the opening edge portion 14 of the container body 10, the notch is deformed by the stress received from the cap member and the opening edge portion and is always opened. Therefore, it is desirable to form the notch at a position other than the peripheral edge of the cap material.

In the above-mentioned embodiment, the two contact closing plates are arranged so as to overlap each other to prevent water leakage more completely, but only one contact closing plate may be provided. Also, as the close contact plate, a thin cork plate, a mesh with a fine mesh, a resin plate with many fine pinholes formed, a thin plate that itself has oxygen permeability, and cut with other materials. Any material that has flexibility and, as a result, has oxygen permeability, such as a stuffed material, may be used.

In the above-mentioned example, as a result of an experiment in which several small fish were put inside, no weakness or death of the small fish due to oxygen deficiency was observed for 2 weeks or longer. Further, in order to confirm the effect on the configuration of the above-mentioned example, a comparison experiment was conducted under bad conditions in which small fish were stored in a smaller bottle. This comparison experiment was conducted by putting 150 ml of water and 50 ml of air into a wide-mouthed bottle having a capacity of 200 ml and an aperture of 55 mm, and putting 3 M of Sebra Danio into the water temperature of 26 ° C. It was This species is resistant to disease and rarely die of it.

Two pieces of 0.5 mm-thick foamed polyethylene were put into this opening as tight contact closing plates and tightened with the same cap member as in the above-mentioned embodiment. A 20 mm cut was made at the center of the tight closing plates. I put it in. In the other two, the progress was observed as it was with a tightly closed plate with no notch, and a state in which it was sealed with a cap member. The results are shown in Table 1.

[0033]

[Table 1]

As shown in Table 1, in each of the two bottles in which the tight closing plate was not cut, the fish started to lift their noses due to lack of oxygen on the second day, and all died on the third day. Here, the circles show normal cases, the triangles show oxygen deficiency symptoms, and the crosses show deaths. The numbers on the right side of these marks are the values of dissolved oxygen content of water in the bottle measured with a commercially available reagent.

On the other hand, in the notched bottle, the dissolved oxygen amount slightly decreased in 3 to 4 days, but thereafter, the state continued, and no death of fish was observed for 2 weeks or more. Also, although this bottle uses a single contact closure plate, no water was spilled when it was laid down or turned upside down.

[0036]

[Effect of device]

 As described above, according to the present invention, by sandwiching the closing plate having flexibility and oxygen permeability between the opening and the cap member, the opening is sealed by the flexibility of the closing plate. In addition, since the cap member has a small opening, the oxygen-permeable closing plate can ensure the flow of oxygen inside and outside the container through the small opening. Since it can withstand the internal water pressure, it is supported by the cap member even when the container is tilted or reversed, and the closing plate does not deform outwards and the internal water does not overflow.
