Description

[Detailed description of the invention] [Industrial application field] This invention relates to an aquarium that can transport live fish directly from the place of production to a restaurant, and also serves as a tank for transporting live fish at the store.

[Conventional technology]

Conventionally, when live fish are mainly transported by air from distant production areas to consumption areas in large cities, transparent nylon double bags 21 are used, with oxygen sealed inside, as shown in Figure 7. The mouth portions are each bound with a rubber band 22.

In this double-bagged live fish transport bag, the fish is transferred to a truck with an aquarium at a wholesaler and then transported to a restaurant.

Live fish restaurants also have transparent aquariums installed to display live fish inside the store.

[Problem that the invention attempts to solve]

However, this double-bagged live fish transportation bag has a problem in that the oxygen that was injected through the opening bound with a rubber band tends to leak, and the live fish may die during long-term transportation.

In addition, these live fish transportation bags have poor airtightness and poor loading efficiency, so they have to be transferred to a truck with an aquarium at a wholesaler, etc., and are passed through nets many times between the production area and the restaurant. Since the fish were scooped up, there were problems in that the live fish weakened and the fish bodies were damaged.

Furthermore, when a live fish restaurant installs a live fish aquarium in the store, it costs a considerable amount of money to include incidental equipment such as a filtration device, and there are also problems such as the installation reduces the number of customer seats.

[Means for solving problems]

In order to solve the above-mentioned problems, this idea was developed to create a water/fish access bag that is open at the top and closed at the bottom along the outer surface of one side wall of the rectangular parallelepiped bag body, which is made of a transparent flexible film and is airtight. A vertical cylinder body is provided in series, and a passageway is provided from the lower end of the vertical cylinder body to the inner bottom of the bag body, and an air port with a plug for pressurizing oxygen is attached to the top wall of the bag body, and the passageway is connected to the top wall of the bag body. It is formed into a flat cylindrical shape from a check valve whose lower edge of the side wall is bent inward to extend into the bag body, and a valve seat made of a soft film whose one end edge is fixed to the lower edge of the vertical cylindrical body.

[Effect]

According to this invention, when water is poured into the vertical cylinder, the passage consisting of the check valve and the valve seat closes due to water pressure, and when air or oxygen is injected through the air port with an oxygen injection plug, the water-filled bag is closed. The body expands into a rectangular parallelepiped shape. At this time, the vertical tube made of soft film and the side wall are tensioned in the plane direction and come into close contact with each other, while the passage consisting of the check valve and the valve seat is flattened and brought into close contact with the tension. , the entire aquarium becomes watertight and airtight. Since the passage is made of a soft film and is located at the bottom of the bag body below the water surface, the passage is subjected to water pressure added to the internal pressure of the container, thereby further ensuring the close contact. In addition, the rectangular parallelepiped-shaped bag body has good loading efficiency during transportation and can be used as a water tank in a store, and the flexible check valve can be easily opened from the outside to store water, oxygen, etc. It can be removed and folded.

〔Example〕

1 to 6 show examples of this invention. This aquarium for transporting live fish has a narrow side wall 2 of a rectangular parallelepiped bag body 1 formed airtight using a relatively thick and strong transparent soft film.
A vertical cylindrical body 3 for taking in and out of water and fish, whose upper end is open and whose lower end is closed, is airtightly arranged on the outer surface of the bag, and a slit-like passage 4 (see Fig. 2) communicating with the bag body 1 is provided at the lower end. and an air port 5 with a small plug for pressurizing oxygen is attached to the other end of the top wall of the bag body 1,
The passage 4 is provided with a check valve 6 made of a transparent soft film of the same fabric.

The bag body 1 has a cut cloth 7 that connects the upper half of the side wall from the top wall, a cut cloth 7' that connects the lower half of the side wall from the bottom wall, and a narrow pair of side walls 2 and 2' that are heat set by a high frequency welder. The welded edges 8 form an airtight joint. The plugged air port 5 has a check valve inside to maintain reliable airtightness.

The length of the vertical cylinder 3 is higher than that of the bag body 1, and the vertical cylinder 3 is made of a soft film that can be folded over the top wall during transportation (see Fig. 6) and easily adheres to the top wall.
Since the bag body 1 is completely folded, perfect watertightness can be maintained, and since the passage 4 is submerged in water, the air chamber in the upper half of the bag body 1 can also be kept completely airtight.

As shown in FIGS. 2 and 5, the lower end of the vertical cylinder 3 is provided with a transparent soft film of the same fabric that is integrally fixed to the welded edge of the lower edge of the vertical cylinder 3 and runs along the bottom surface. There is a shaped valve seat 9, and a check valve 6 connected to the lower edge of the side wall 2 and a valve seat 9 of substantially the same shape opposing this are fixed by welded edges 10 on both ends to form a flat passage 4. .

At the free ends of the valve seat 9 and the check valve 6, there is a circular welded part 11 (a fourth
(see figure details). This check valve 6
When water is injected from the vertical cylindrical body 3, the maximum water pressure acts on the bottom surface of the reservoir, causing it to come into close contact with the valve seat 9 (see Fig. 3). When air or oxygen is injected through the air port 5, the bag body 1 expands and maintains its rectangular parallelepiped shape, and the check valve 6 and valve seat 9 are pulled along the length of the welded edge 8. In addition to the close contact, the outer fabric and inner fabric of the vertical cylinder body 3 also come into close contact, making it possible to maintain watertightness, and since the passage 4 is submerged in water, air leakage from the upper half of the bag body 1 can be completely prevented. It becomes like this.

When using this devised aquarium for transporting live fish, 60 to 70% of water is injected into the bag body 1 from the upper end opening of the vertical cylinder 3 at the production area, and the live fish are
(see details in Figure 2), pressurize the required amount of oxygen from the air port 5 with a stopper, fold the vertical cylinder 3 onto the top surface,
Packaging is completed by storing it in an outer box 12 made of expanded polystyrene and covering it with a lid. Note that a cardboard case may also be used as the outer box.

In this way, when a rectangular parallelepiped outer box is used, there is no wasted space during air or land transportation, resulting in good loading efficiency. This aquarium for transporting live fish can withstand long-term transportation because there is no oxygen leakage, and it is transported as-is from the production area, wholesaler, to restaurant, and when taken out from the outer box at the store, it is transparent and rectangular. Because of this, it will soon become an exhibition tank.

In addition, when taking out the live fish inside, when the vertical cylinder 3 is raised and a hand is inserted, the passage 4 is easily opened because it is made of a soft material, and the fish body is not damaged. Also, after use, you can fold the drain and send it back to us so that it can be reused many times as a returnable bag.

〔effect〕

As described above, the aquarium for transporting live fish according to this invention is a transparent rectangular parallelepiped with a vertical cylinder connected to one side for the entry and exit of water and fish, and a check valve installed in the lower end passage. , it has many advantages as listed below.

(1) Since it is a rectangular parallelepiped, it has good loading efficiency during transportation, and when stored in an outer box, it is safe even if it is stacked considerably.

(2) Complete airtightness is maintained and the pressurized oxygen does not leak, so it can be maintained for a long time, and it can be transported from the production area to the restaurant without using a tank-equipped fish truck, reducing transportation costs. (3) As mentioned above, since direct shipping is possible, there is no need to scoop up and transfer live fish, and healthy fish can be supplied without any damage to the fish body.

(4) Since fish tanks can be used at live fish restaurants, there is no need to install a fixed fish tank in advance, so equipment costs can be reduced.
