BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to an embodiment of the present invention shown in the accompanying drawings.

FIG. 1 is a front view of a portable water tank of the present invention, and FIG.
Is a vertical sectional front view thereof, FIG. 3 is a transverse sectional view taken along line 3-3 of FIG. 2, FIG. 4 is a transverse sectional view taken along line 4-4 of FIG.
FIG. 6 is a diagram showing a process of attaching the water tank base to the aquarium main body, and FIG.

The portable water tank T is composed of a water tank body 1 and a water tank base 2 which are watertightly and detachably fitted to each other.

The water tank body 1 is formed of a transparent synthetic resin material such as a transparent acrylic resin material by injection molding or the like into a hollow cylindrical shape with an open lower surface, and is slightly expanded from the upper surface to the lower surface. A gradient is formed. A feeding port 3 is opened at the center of the upper surface of the aquarium body 1, and the feeding port 3
Is watertightly closed by a transparent or translucent lid 4. The lower surface of the water tank body 1 is open, and the water tank base 2 is detachably fitted to the open lower surface 5 in a watertight manner. Further, on the inner peripheral surface of the open lower surface 5, four hook-shaped engaging grooves 6 are formed at intervals in the circumferential direction.

On the other hand, the aquarium base 2 is formed of a transparent synthetic resin material such as a transparent acrylic resin material into a circular container shape, and four peripheral portions are formed on the outer peripheral surface thereof with a space above and below the space. The engaging protrusions 7 ... Are integrally formed with the outwardly facing stopper flange 8, and the engaging protrusions 7 ...
The engaging groove 6 can be detachably engaged with the stopper flange 8, and the stopper flange 8 receives the lower edge of the water tank body 1. A ring groove 9 is formed in the upper part of the outer peripheral surface of the water tank base 2, an O-ring 10 is fitted in the ring groove 9, and a mounting boss is attached to the center of the bottom wall of the water tank base 2. 11 is provided so as to integrally project upward, and the attachment boss 11 is provided with a dead end attachment hole 12 on the upper surface thereof.

On the upper surface of the opening of the water tank base 2, an aquatic plant implant plate 14 made of a porous elastic material such as a sponge is detachably fitted. As clearly shown in FIG. 6, the aquatic plant implanting plate 14 is formed in a disc shape, and a fitting hole 15 capable of being fitted into the mounting boss 11 is formed in a central portion thereof. . Further, the aquatic plant implant plate 14 has a plurality of X-shaped notches 16 penetrating the upper and lower surfaces thereof as shown in FIG. 6 (A).
Is irregularly cut by the cutter C. Then, as shown in FIG. 6 (B), aquatic plants G are planted in these notches 16 with scissors such as tweezers P, and the roots of these aquatic plants G pass through the aquatic plant planting plate 14 and form the lower surface thereof. Make it more exposed.

In a vessel-shaped water tank base 2, pebbles 1 such as Oiso
8 groups are accommodated, and the aquatic plant implant plate 14 is provided on the upper surface of the opening.
Can be detachably attached. That is, aquatic plant 14
Has its outer peripheral surface fitted to the upper surface of the opening of the aquarium base 2 and its fitting hole 15 fitted to the mounting boss 11 and then fitted to the upper surface of the aquatic plant implant plate 14 in a poppet-like mounting piece 17. The insertion pin of is inserted into the mounting hole 12 of the mounting boss 11 so as to be freely inserted and removed. As described above, the group of pebbles 18 accommodated in the aquarium base 2 is fixed by the aquatic plant implant plate 14, and even if the aquarium base 1 is turned over, the group of pebbles 18 does not fall down, and the aquatic plant is implanted. The plate 14 does not fall.

Next, the procedure for assembling the portable water tank T will be described. After accommodating a group of small stones 18 such as Oiso in the water tank base 2, the water grass planting plate 14 in which the water grass G is planted is attached to the water tank base 2. Attach it to the upper surface of the opening as described above.

On the other hand, as shown in FIG. 5, the aquarium body 1 is turned upside down, water W is poured therein, and a few small fish F are used as ornamental fish.
Insert At this time, the void A is left in the aquarium body 1. Next, the aquarium base 2 in which the aquatic plant G is planted is turned upside down, and the four engaging projections 7 of the aquarium base 2 are fitted while watertightly fitting the aquarium base 2 through the O-ring 10 to the open lower surface 5 of the aquarium body 1.
Are aligned with the four hook-shaped engagement grooves 6 of the water tank body 1, and the water tank base 2 is pushed toward the water tank body 1 and slightly rotated in one direction (direction of arrow a in FIG. 5). As shown in FIGS. 1 and 2, the engaging projections 7 ... Engage with the hooks of the engaging grooves 6 ... And the stopper flange 8 is abutted against the lower edge of the water tank body 1, The open lower surface 5 is watertightly coupled to the water tank base 2 via the O-ring 10 to assemble the portable water tank T.

Next, as shown in FIG. 2, this aquarium T is inverted to make it upright, and it is placed on a desk or the like so that the aquatic plants G and small fish F can be seen through the aquarium main body 1 and viewed. be able to. The presence of the void A in the upper part of the water tank T enables effective oxygen replenishment of water in the water tank T, and by shining light on the water tank T,
Aquatic plant G can be grown by promoting its own photosynthetic action and by using the feces of small fish F as a fertilizer, while small fish F is supplemented with oxygen and fed with aerobic microorganisms that propagate in water. Can be made to grow, and even if the water tank T is sealed, the small fish F are rarely killed or the waterweed G is hardly killed, and the water is not polluted. The small fish F and aquatic plants G can be bred and raised for a long period of time by removing the lid 4 and feeding from the feeding port 3 with almost no water change.

It is desirable that the small fish F should not be put in too much and not fed too much.

Further, by periodically inverting the water tank T (about once a day), oxygen is mixed into the water and aerobic microorganisms that propagate in the pebbles 18 group are mixed into the water. Oxygen supplementation and feeding can be performed. In this case, the group of pebbles 18 is fixed by the aquatic plant implant plate 14 and does not scatter in the aquarium T, and the aquatic plant G is securely held without being damaged by the resilience of the aquatic plant implant plate 14. , I never deliberately float in the water.

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various embodiments are possible within the scope of the present invention. For example, although the water tank main body is formed in a cylindrical shape in the above-described embodiment, it may be formed in a rectangular tube or other cylindrical shape, and the water tank may be formed in a semitransparent or opaque part. In addition to the sponge, it is needless to say that other well-known porous bullet crush bodies may be used as the aquatic plant implant plate.

[0020]

As described above, according to the invention described in each claim of the present invention, it is possible to provide a portable aquarium having a small number of parts, a simple structure, and a low cost. Oxygen can be reliably supplied and aquatic plants can be effectively photosynthesized, which enables healthy growth of ornamental fish and aquatic plants, and also improves the circulation of water to improve the turbidity. Can be suppressed. In addition, the aquatic plant plate securely holds the aquatic plant as a buffer, prevents the aquatic plant from floating in the water, does not damage the aquatic plant, and can also be used as a fixing member for the pebbles. . Furthermore, the aquatic plant can be used as a feed for ornamental fish or as a breeding bed for aerobic microorganisms that effectively functions as an organic purification element for water.
