Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a fish storage container, and more specifically, to a fish storage container called an Otori can for storing Otori sweetfish used for sweetfish fishing, for example.

(Prior art) For example, a fish storage container called an otori can, which is used to store otori ayu used for sweetfish fishing and carry it to a fishing spot, or to keep it immersed in water at a fishing spot, is a portable fish storage container. In order to prevent Otori Ayu from weakening during transportation and to ensure that they remain healthy when stored, a porous air discharge device (air It is constructed so that air (oxygen) is constantly discharged from the container into the water inside the container.

On the other hand, at a fishing spot, fresh water is actively introduced into the container and the container is kept immersed in water to prevent an increase in water temperature and oxygen deficiency. In this case, the container is appropriately tethered to the riverbank via a string, but it is necessary to limit the degree of freedom of the container to prevent spontaneous floating or irregular movement caused by water current.

Therefore, a stone block or the like is simply put into the container as a weight, and the container is immersed in water.

(Problem that the invention aims to solve) In the conventional fish storage container configured in this way, air is discharged into the water inside the container from an air discharge device called an air stone, which causes air to be locally biased. In the discharge state, air cannot be discharged over a wide area, and the air bubbles discharged from the air stone have a relatively large particle size, so there is a problem that oxygen intake efficiency is poor.

In addition, weights such as stone blocks placed in the container,
Since it is simply being put into the container, there is a large degree of freedom within the container, and since the shape is three-dimensional and bulky, there is a risk of colliding with the male ayu and damaging the male ayu, and furthermore, the container posture is unstable. It has the problem of being damaged.

This idea was made in view of the background of the conventional technology, and it not only blows out air over a wide area of the container, but also blows out fine bubbles to improve the oxygen intake efficiency. It is an object of the present invention to provide a fish storage container which can limit the degree of freedom and form the weight in a planar manner to have a low bulk to prevent damage to Otori Ayu and further ensure stabilization of the container posture in water. .

(Means for Solving the Problems) The fish storage container according to this invention is provided with a plate-shaped weight for stabilizing the posture on the bottom plate of the container body, and a groove is formed upward in the bottom plate. An air discharge tube for discharging air into the container body is fitted into the container body, and the plate-shaped weight for attitude stabilization and the air discharge tube are fixed to the bottom plate via a fixing mechanism.

(Function) In this invention, air is discharged over a wide area of the container body from the peripheral wall of the air discharge tube that fits into the groove formed in the bottom plate.
Moreover, the degree of freedom of the air discharge tube and the plate-shaped weight for posture stabilization can be restricted by the fixing mechanism.

(Example) Fig. 1 is a partially cutaway perspective view of an embodiment of the fish storage container according to the invention, and Fig. 2 is a plan view of the bottom plate. It consists of a container body 2 and a lid 3 that removably closes the upper opening of the container body 2.The container body 2 is formed of synthetic resin into a box shape with a bottom, and the lid 3 is connected to the fish storage container 1. a screen-shaped reflux port 3A that introduces water into the container body 2 and brings out the water in the container body 2 to actively reflux the water when the container is immersed in water;
An opening/closing lid 3B is provided for putting in and taking out baited sweetfish or caught sweetfish, and this opening/closing lid 3B always elastically closes the entrance/exit 3C.

The container body 2 has an upward annular groove 4 formed on its bottom plate 2A. As shown in FIG. 3, this groove 4 is formed into a rectangular ring shape by having rib-like protrusions 4a and 4b facing each other at a predetermined width interval W on the bottom plate 2A. A branch groove 4A extending toward the side wall 2B of No. 2 is formed, and a rising groove 4B communicating with the branch groove 4A is further formed on the inner surface of the side wall 2B.

Reference numeral 5 denotes a plate-shaped weight for stabilizing the posture, which is formed into a rectangular plate shape from a high specific gravity material such as lead, and is fitted into a recess 6 surrounded by an inner circumferential protrusion 4a in the rectangular annular groove 4. . That is, the vertical and horizontal dimensions of the posture stabilizing plate-shaped weight 5 are set to such a size that it can be fitted into the recess 6 without wobbling, and the wall thickness (height) is set to a size that allows the plate-shaped weight 5 to fit into the recess 6 without rattling. The height is set approximately equal to the height of 4b.

Reference numeral 7 designates an air discharge tube, which is made of rubber or synthetic resin, and has a large number of air discharge holes 7a formed through its peripheral wall, and is fitted into the groove 4. That is, the air discharge tube 7 is connected to the groove 4.
It has an outer diameter that can fit into the annular shape of the groove 4, and a length dimension that can fit into the annular shape of the groove 4.

The air discharge tube 7 is connected to an air supply tube 8 (see FIG. 1) via a T-shaped connecting tube (not shown) at one corner of the groove 4 formed in a rectangular ring shape. The supply tube 8 fits into the rising groove 4B, rises along the side wall 2B of the container body 2, passes through the upper part of the side wall 2B, is led out, and is detachably attached to the outer surface of the container body 2. The air pump (not shown) is connected to the outlet of the air pump (not shown).

9 indicates a fixing mechanism. This fixing mechanism 9 fixes the plate-shaped weight 5 for posture stabilization on the bottom plate 2A, and also
This is to prevent the air discharge tube 7 from separating from the groove 4, and in this embodiment, as shown in FIGS. 2 and 3, it is slightly longer than the plate-shaped weight 5 for stabilizing the posture. It is composed of a wide holding plate 9A made of synthetic resin and fasteners 9B, such as screws, for fixing the holding plate 9A to the bottom plate 2A. Therefore, the plate-shaped weight 5 for stabilizing the posture is the presser plate 9.
The air discharge tube 7 is pressed and fixed on the bottom plate 2A with substantially the entire lower surface of the holding plate 9A, and the air discharge tube 7 is attached to the lower corner of the peripheral edge of the holding plate 9A,
That is, it interferes with the lower edge portion 9a and is prevented from leaving the groove 4.

In the above configuration, in the water inside the container body 2,
A large number of small air discharge holes 7 of the air discharge tube 7
Air is expelled from a. That is, since the air discharge tube 7 is fitted into the rectangular annular groove 4, the air is discharged over a wide area of the container body 2, and is discharged as fine bubbles, so that the oxygen intake efficiency is improved. It is possible to effectively prevent, for example, a male sweetfish from weakening while the fish storage container 1 is being carried and moved, and to ensure that the fish is in a healthy state when stored.

In addition, the attitude of the fish storage container 1 at the fishing spot is stably controlled by the plate-shaped weight 5 for stabilizing the posture, and when the water depth is shallow, the fish storage container 1 is fixed on the bottom of the water, and when the water depth is deep, the fish storage container 1 is placed on the bottom. The container 1 is suspended and immersed in the middle in a substantially erect posture. The plate-shaped weight 5 for stabilizing the posture is fixed on the bottom plate 2a of the container body 2 by a fixing mechanism 9, and its degree of freedom is controlled, and the weight itself is configured to have a low bulk in a plan view. Therefore, it is possible to avoid collisions between the male sweetfish and the damage to the male sweetfish can be reliably prevented.

In the above embodiment, the groove 4 is formed by rib-shaped protrusions 4a and 4b that protrude opposite to the bottom plate 2A, but as shown in FIG. The groove 4 may be formed in a recessed manner. Although the shape pattern of the grooves 4 is described as being rectangular and annular, this formation pattern is not limited to the above-mentioned embodiments, and any pattern can be selected and adopted.

Furthermore, although the fixing mechanism 9 has been described as consisting of a presser plate 9A and a stopper 9B such as a screw, this fixing mechanism 9 is not limited to the embodiments described above, and for example, as shown in FIG. As shown in FIG. 6, a configuration in which a plurality of presser plates 9C that can be horizontally pivoted about an axis from the position shown by the solid line to the position shown by the imaginary line on the bottom plate 2A can be provided also produces the same effect as the above embodiment. .

(Effects of the invention) As explained above, according to this invention, the air discharge tube is fitted into the groove formed in the bottom plate,
Since this air discharge tube is configured to discharge air into the water, air bubbles with fine particle size and high oxygen intake efficiency can be discharged over a wide area within the container body, and the fish storage container For example, it is possible to effectively prevent the deterioration of Otori Ayu during transportation, and to ensure that it remains in good health when stored.

In addition, since the plate-shaped weight for posture stabilization is fixed on the bottom plate by the fixing mechanism, it is possible to properly and stably control the posture of the fish storage container in the water, and the plate-shaped weight for posture stabilization can be controlled properly and stably. This, together with the fact that the plate-shaped weight for stabilizing the posture is flat and low in bulk, can avoid collisions with the Otori Ayu and reliably prevent damage to the Otori Ayu.

Furthermore, since the air discharge tube is fixed by the fixing mechanism, the air discharge tube is prevented from separating from the groove, and the air discharge pattern is damaged as the air discharge tube separates from the groove over time. As a result, there is an advantage that the inconvenience of unevenly distributed air discharge conditions can be avoided.
