Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field of the Invention> The present invention relates to an aquarium for transporting live fish, and more particularly to an aquarium for transporting live fish in which oxygen is sealed in a container.

<Technical background of the invention and its problems> Conventionally, when fish and shellfish such as live fish for aquaculture or ornamental use are shipped or purchased on the market, water and live fish are placed in a plastic bag, and then oxygen is sealed under pressure. Then, after sealing the opening of the bag with string, etc., the bag was placed in a cardboard box, etc., and transported.

However, since the bag is made of plastic, the sealed oxygen may leak from the opening of the sealed bag or the minute bolus part that allows air to pass through due to the material of the plastic bag, or the bag may be damaged or perforated during transportation. Because the water in the aquarium leaks out, live fish and the like become weakened, significantly reducing their commercial value.

Furthermore, it was necessary to seal off oxygen each time live fish, etc. were brought in and taken out.

In addition, in large live fish tanks, in which many types of live fish are often mixed and transported in the same tank, it is extremely complicated to separate the fish by type after transport.

Furthermore, it was inconvenient to load and unload cardboard boxes that had leaked into the water, and accidents such as falling occurred frequently, resulting in large losses. Moreover, in recent years, the demand for live fish for raw consumption has increased, and there has been a need to design aquariums for transportation, display, or low-temperature storage.

In addition, a container for transporting live fish (Japanese Patent Application Laid-Open No. 1983-1999) is a container filled with oxygen and has a partition cage that serves as a storage area for supporting each live fish so that it does not move, and the body of the live fish is partially submerged in water. 58429), fish protect their body surfaces with mucous membranes (slimy) on their epidermis.
If you keep healthy fish in such a small mold chamber, they will shed a lot of their slime, and it will take a long time for them to recover, and they will be more susceptible to diseases, so be sure to take special care of their body surface. The drawback is that it is not suitable for transporting live ornamental fish for long periods of time.

<Purpose of the Invention> The present invention has been made in view of the above-mentioned social demands and eliminates the above-mentioned difficulties.It prevents the leakage of oxygen sealed in a container and prevents accidents caused by breakage during transportation. The purpose of the present invention is to provide an aquarium for transporting live fish, which is suitable for long-term transportation, display, or low-temperature storage of live fish, etc., without reducing the commercial value of the live fish.

<Means for Solving the Problems> In order to achieve this object, the aquarium for transporting live fish of the present invention comprises: an open container that can be filled with water; a wall member that slides into contact with the inner wall surface of the container; and the wall member. and an upper lid consisting of a lid member that is formed integrally with the container and placed on the open top surface of the container, and the lid member of the upper lid is provided with an opening, and the opening is provided with an opening for introducing oxygen into the container. After oxygen has been sealed in the container, a stopper is provided with a supply pipe for supplying oxygen and a drain pipe whose one end reaches a predetermined position in the depth of the container and drains a predetermined amount of water in the container. A cap is provided to seal the opening.
