A handle 12 is integrally formed on the upper wall of the tank body 11, and large and small inlets and outlets 13 and 14 closed by screw-type lids are provided on the left and right sides of the upper wall, respectively.

The small tank 10 also includes a first leg member 15 and a second leg member 16 capable of supporting the left and right sides of the tank body 11.

Each of the first leg member 15 and the second leg member 16 is formed by bending a metal wire rod. The first leg member 15 and the second leg member 16 are bent in a U-shape, and a grounding portion 17 capable of grounding and a U-shape. Correspondence between the abutting portion 18 that is curved and abuts on the surface of the bottom portion 11a of the tank main body 11, and the grounding portion 17 and the abutting portion 18 in the state of facing each other in the same direction. A pair of connecting portions 19 that connect the end portions to each other, an extension portion 20 that extends the connecting portion 19 to the outside of the contact portion 18, and a pivot portion 22 that is provided on the extension portion 20 and is described later. It is equipped with the bearing part 21 to fit.

In addition, in the first leg member 15 and the second leg member 16, the open portions of the ground contact portion 17 and the contact portion 18 are the tank body with the ground contact portion 17 facing upward and the contact portion 18 facing downward. The left and right side end portions 11L and 11R each of which is composed of two wide side walls 11b and one narrow side wall 11c are elastically fitted and locked.

Furthermore, the length L1 of the connecting portion 19 of the first leg member 15 and the length L2 of the connecting portion 19 of the second leg member 16 are different (L1> L2). That is, the first leg member 15 and the second leg member 16 have different leg lengths.

Then, the first and second leg members 15 and 16 release the locking at the locking position A and rotate outwardly around the bearing portion 21 to ground the grounding portion 17. At the same time, the contact portion 18 is brought into contact with the bottom portion 11a so that the tank body 11

The bearing portion 21 is rotatably attached to the tank body 11 while being axially supported by a shaft portion 22 projecting from the tank body 11.

Therefore, according to the small tank 10 according to this embodiment, the first and second leg members 15 and 16 are set to the locking position A as shown in FIGS. . In this case, the first and second leg members 15 and 16 are made stationary, and fitted to the side end portions 11L and 11R of the tank body 11 so as to be along the wall portion, and do not project outward. Therefore, since it does not hinder the transportation, it does not hinder the transportation, and when a large number of small tanks 10 are lined up, it does not take up an extra space and can be handled in the same manner as the conventional small tank 1.

Also, when removing kerosene from the small tank 10,
As shown in the figure, the first and second leg members 15 and 16 are set to the support position B, the kerosene tank 5 is brought near the small tank 10, and the inlet / outlet 14 on the side of the short second leg member 16 is provided.
A suction pipe 7 of a manual or electric simple pump 6 is inserted into this and the simple pump 6 supplies kerosene to a kerosene tank 5 of an oil stove. In this case, since the bottom portion 11a of the tank body 11 is higher than the kerosene tank 5 by the first and second leg members 15 and 16, even if the liquid level in the tank body 11 becomes low, the Since the liquid level with respect to the ground is high, it is possible to secure a head for the kerosene tank 5, and since the principle of the siphon can also be used, the siphoning load does not become too large and the kerosene can easily flow out. It is possible to refuel efficiently.

Furthermore, since the length L1 of the connecting portion 19 of the first leg member 15 and the length L2 of the connecting portion 19 of the second leg member 16 are different, the bottom portion 11a of the tank body 11 is inclined. Therefore, even if the amount of kerosene decreases, the kerosene will be collected by the second leg member 16 being pushed toward the bottom 11a of the crocodile. Therefore, the kerosene can be refueled by raising the liquid level of a small amount of kerosene, and the suction efficiency is improved accordingly. Also,
Since the kerosene is drawn, the kerosene can be sucked up with almost no residue in the tank body 11, and the kerosene can be used without waste.

4 to 6 show a small tank 30 according to another embodiment of the invention of the first item.

Unlike the above-described embodiment, the small tank 30 according to this embodiment includes one leg member 31.

The leg member 31 is formed in the same manner as described above, and the locking position A at which the one side end portion 32L of the tank body 32 is elastically fitted and locked, and the locking position A at which the locking is released. 33 so as to rotate outwardly so that the grounding portion 34 is grounded and the contact portion 35 is brought into contact with the bottom portion 32a so as to be positioned at two positions including the support position B for supporting the tank body 32. The bearing portion 33 is rotatably attached to a shaft portion 36 projecting from the tank body 32 while being pivotally supported.

Therefore, also in the small tank 30 according to this embodiment, the bottom portion 32a of the tank main body 32 can be raised and the bottom portion 32a can be tilted by the leg members 31, so that the oil can be efficiently refueled as described above.

FIG. 7 and FIG. 8 show a small tank 40 according to the embodiment of the invention of the second item.

The small tank 40 according to this embodiment is constructed in substantially the same manner as the former embodiment of the invention of the first paragraph, but unlike the above, the second leg member 16 with short legs has a narrow side wall 11c. A discharge port 41 for discharging the liquid in the tank body 11 is provided in the lower portion, and a hose 42 is connected to the discharge port 41. A manual opening / closing valve 43 is provided at the tip of the hose 42.

Therefore, when the kerosene is taken out from the small tank 40 according to this embodiment, the first and second leg members 15 and 16 are set to the support position B as shown in FIG.
Bring the kerosene tank 5 of the oil stove near, and insert the tip of the hose 42 into the oil inlet 5a of the kerosene tank 5 to open the open / close valve 43. In this case, the small tank 40 includes the first and second leg members 15 and 16 at the bottom 11a thereof.
Is higher than the kerosene tank 5 and the discharge port 41 is located at the bottom, the kerosene can always flow out from a high place to a low place. Therefore, even if the simple pump 6 is not used. You will be able to refuel easily.

Furthermore, since the length L1 of the connecting portion 19 of the first leg member 15 and the length L2 of the connecting portion 19 of the second leg member 16 are different, the bottom portion 11a will be This causes the kerosene to lean, so that the second leg member 16 is brought closer to the bottom part 11a of the mortar, so that the kerosene can be drained without waste. Other functions and effects are similar to those of the above embodiment.

In addition, in each of the above-described embodiments, the length of the leg member may be appropriately determined. In addition, in the above embodiment, the first and second leg members 1
Although the lengths of 5 and 16 are different, the length is not limited to this and may be the same. Furthermore, the shape and the number of leg members are not limited to those described above, and may be set appropriately. Furthermore, the small tank is applicable not only to kerosene but also to various liquids. Further, the material of the tank body is not limited to resin. Further, as shown in FIG. 9, in order to keep the small tank 1 inclined, the inclined surface 5 on which the small tank 1 is placed is placed.
It is proposed that the mounting table 50 having 1 is effective.

[Effects of the Invention] As described above, according to the small tank of the first aspect of the invention, since the leg members can be locked to the tank body and kept stationary, it is less likely to get in the way and to be transported. It is possible to prevent a situation in which a large number of small tanks are arranged side by side. Also, the leg members are
Since the metal wire is bent, it is lightweight and easy to manufacture, and the structure is complicated because it is rotatably supported by the shaft provided below the side end of the tank body. It can be easily manufactured and the cost can be reduced.

Further, even if it is formed of a wire rod, the contact portion receives the bottom portion of the tank body, so that the strength can be secured and the support can be stabilized. Moreover, since the leg member can be fitted to the side end portion of the tank main body in the locking position and can follow the wall portion,
It does not project to the side and can be stored without specially providing a storage portion, and the capacity of the tank can be secured accordingly.

Furthermore, when the liquid in the small tank is taken out, if the leg member is set to the supporting position, the bottom of the tank main body can be raised, so that even if the liquid level in the tank main body becomes lower, The liquid level can be increased, and the liquid can easily flow out accordingly, and the liquid can be efficiently supplied.

Further, since the leg member inclines the bottom portion of the tank body at the supporting position, even if the liquid becomes less, the liquid can be gathered closer to one side of the bottom portion and stored, so that the liquid level of the less liquid can be increased. Therefore, it becomes possible to suck up almost no liquid from the inlet and outlet, etc.
Has various effects.

Further, according to the small tank of the second aspect of the invention, when the leg member is set to the supporting position and the liquid is discharged from the discharge port, the bottom of the tank main body is raised and the discharge port is located at the lower part. The liquid can be constantly made to flow from a high place to a low place, so that even if the liquid level in the tank main body becomes low, the liquid can be efficiently supplied.
