Description

  The present invention relates to a container for transporting live fish that is particularly suitable for transporting and storing fish and shellfish such as live fish and shellfish while maintaining the state as it is.

In the container for transporting live fish, for example, an air blowing part connected to the tip of an air hose extended from an air pump attached to the outside of the container is placed in the container, and air is supplied to the water in the container, Transporting live fish while keeping them alive is performed.
However, since the water in the container is contaminated by the discharge of fish and the like, it is necessary to purify the water. Therefore, the water in the aquarium (container) containing live fish is drained from the bottom side, the filtered water is supplied from the top surface to circulate the water, and the water drained from the aquarium is filtered between these pipes. A purifying device comprising a filtering device for this purpose and a pump for returning the water filtered by this filtering device to the piping on the water tank side has been proposed so that fish can be transported alive for a long time. (For example, refer to Patent Document 1).
Japanese Patent Publication No. 6-18500 (see FIG. 1)

The large-scale purification apparatus as described in Patent Document 1 requires a place for installing the purification apparatus, so that not only a large amount of live fish can be transported, but also there is a disadvantage in terms of cost. Therefore, there was room for improvement. In addition, since such a large purification device requires a large container itself, a dedicated transportation truck or the like for permanently installing them is required, which is further disadvantageous in terms of cost. It was a thing.
By the way, considering only the cost, it is conceivable to put a filter for purification in the live fish transport container, but by simply leaving the filter in the container, the water in the container efficiently passes through the filter. Therefore, as a result of not being able to exert a sufficient purification action, there was almost no difference from the case where no purification filter was inserted.

  In view of the above-mentioned situation, the present invention intends to provide a live fish transport container that can favorably purify water in the container while being advantageous in terms of cost.

In order to solve the above-mentioned problem, the live fish transport container of the present invention comprises a container main body in which an opening for inserting live fish is formed from above and a lid for closing the upper opening of the container main body. in the shipping container, allowed a holding portion containing a purifying filter detachably to the lower surface of the lid, the holding unit, wherein forming a housing space which accommodates the purifying filter, a number of the holding portion A water flow opening is provided so that the water stored in the container body can enter and exit the storage space through the water flow opening, and the purification filter purifies the water entering and exiting the storage space. The water in the container body can be purified .
When vibrations such as roll and pitch generated during transportation are transmitted to the container, the oscillating water in the container enters the inside through the water inlet of the holder, and the purification filter stored in the holder is removed. The purified water that has passed through is discharged out of the holding section through another water passage.

  You may comprise the said container main body and a cover body with a foaming synthetic resin.

  The holding part is composed of a peripheral wall part and a bottom wall part connected to the lower end of the peripheral wall part, and the peripheral wall part has a large number of vertically long rod-like bodies arranged at predetermined intervals in the circumferential direction. The bottom wall portion receives the purification filter and is provided with a large number of water passages, and the water passage formed between the rod-shaped bodies adjacent in the circumferential direction is configured to be narrower toward the inside of the holding unit. It is preferable to do this. Furthermore, you may comprise so that the water flow opening formed in the said bottom wall part may become narrow toward the downward side.

  The holding portion may be integrally formed with the lid, and a filter opening for inserting and removing the purification filter may be formed at a specific portion of the lid corresponding to the upper portion of the holding portion.

  The holding part is configured separately from the lid, and an opening for the holding part is formed in the lid so that the separately configured holding part can be inserted from a lower end thereof. When the holding part is inserted from above at the lower end thereof, the opening may be provided with a receiving part for receiving a collar provided at the upper end of the holding part.
