Thus, the liquid 14 can be drained efficiently from the liquid drainage tube part 30, and this is advantageous in achieving efficiency of transferring work of the liquid 14 of the container 12.SELECTED DRAWING: Figure 4

Description

The present invention relates to a liquid outflow jig.

In the equipment for water treatment in factories, liquid chemicals such as chlorine water and sodium hydroxide aqueous solution stored in a large-capacity tank of about 100 liters are used.
Since such chemicals are sold in small-capacity containers of, for example, about 18 liters, when the tank is empty, seven or eight containers of liquid must be transferred from the container to the tank.
According to the investigation by the present inventors, since such work has been performed manually by using a hand pump, it takes about 3 minutes to transfer 18 liters of liquid.
Therefore, when transferring an empty tank to fill it with liquid for 7 or 8 containers, it takes about 1 hour in total including the preparatory work and the post-cleanup work. ..
Therefore, instead of using a hand pump, the present inventors conducted an experiment in which a commercially available cock was attached to the spout of the container and the liquid was transferred directly from the container to the tank via the cock.
As a result, although the manual work of the hand pump could be omitted, the negative pressure inside the container generated by the discharge of the liquid from the container causes air to enter the inside of the container through the cock, a so-called breathing phenomenon. Was found to occur.
Therefore, since the liquid is not smoothly discharged from the container, it takes about 6 minutes to transfer the liquid for 18 liters, and the efficiency of the liquid transfer work cannot be improved.
Patent Document 1 discloses a spout that suppresses the scattering of liquid due to the breathing phenomenon by providing a ventilation path at the spout of a liquid container for seasonings, beverages, etc. and guiding air into the container. Has been done.

Japanese Unexamined Patent Publication No. 2004-1008

However, in the above-mentioned prior art, since the spout is provided with a ventilation hole of the air passage adjacent to the opening for discharging the liquid, when the container is tilted to discharge the liquid from the opening, the air is discharged from the air passage. It is difficult to enter the inside of the container from the container, which is disadvantageous in efficiently discharging the liquid.
The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a liquid outflow jig which is advantageous for efficiently discharging a liquid from a container.

In order to achieve the above object, the present invention is a liquid outflow jig that is detachably attached to a spout of a container, and includes a jig body and an air introduction pipe. The air introduction pipe has a spout attachment portion that is detachably attached to the spout, and a liquid discharge pipe portion that is connected to the spout attachment portion and is provided with a liquid on-off valve. Passes through the inside of the jig body, and in a state where the spout attachment portion is attached to the spout, an inner pipe extending upward from the spout attachment portion inside the container. It is characterized by including a portion and an outer pipe portion extending upward from the jig body outside the container and having an upper end thereof located above the upper end of the inner pipe portion.

According to the present invention, air can be guided to the inside of the container by the air introduction pipe of the liquid outflow jig attached to the spout of the container.
Therefore, since the inside of the container becomes negative pressure as the liquid is discharged, air can enter the container from the liquid discharge pipe portion, and a breathing phenomenon in which the discharge of the liquid is hindered can be prevented.
Therefore, the liquid can be efficiently discharged from the liquid discharge pipe portion, which is advantageous in improving the efficiency of the liquid transfer work in the container.
In addition, since the on-off valve for liquid is provided, the liquid does not accidentally leak from the liquid discharge pipe, which is advantageous in improving the efficiency of the liquid transfer work in the container, and when the container falls over. It is advantageous in preventing the spouting of the liquid in the above and ensuring the safety during work.

If it is integrally molded by using it, it will be further advantageous in reducing the size and weight of the main part.

Next, a method of using the liquid outflow jig 10 will be described.
Keep the air on-off valve and liquid on-off valve closed.
A container 12 filled with the liquid 14 is prepared, and the container 12 is placed so that the spout 1208 of the container 12 faces upward.
Next, the cap is removed from the spout 1208 of the container 12, the inner pipe portion 46 of the liquid outflow jig 10 is inserted from the spout 1208 into the inside of the container 12, and the cap portion 36 of the spout attachment portion 26 is poured. It is attached by screwing it to the mouth 1208.
As a result, the inside of the container 12 is liquid-tightly connected to the inside of the jig main body 20 via the spout attachment portion 26.
Further, when the container 12 is viewed from above, the posture of the liquid outflow jig 10 is adjusted so that the outer pipe portion 50 extends from the spout 1208 toward the corner of the container 12 facing the spout 1208.
Next, the container support jig 18 is placed on the upper wall 1206 so that the groove 1806 faces upward at the upper wall 1206 near the supply port 1604 of the tank 16, and the cap is removed from the supply port 1604 of the tank 16 to remove the tank. The supply port 1604 of 16 is opened.
Then, as shown in FIG. 5, the container 12 to which the liquid outflow jig 10 is attached is lifted, and the container 12 is inserted so that the corner portion of the container 12 on the side where the spout 1208 is provided fits into the groove portion 1806. Place it on the container support plate 1802 of the container support jig 18 on its side, and place the liquid discharge pipe 30 (liquid discharge port 42) directly above the supply port 1604 of the tank 16 so that the container 12 and the liquid outflow control Position the tool 10.

After positioning the container 12 and the liquid outflow jig 10, the air on-off valve and the liquid on-off valve are opened.
Then, the liquid 14 inside the container 12 passes from the spout 1208 to the spout attachment portion 28, the second pipe portion 2404, the first pipe portion 2402, and the liquid discharge pipe portion 30, and from the liquid discharge port 42 to the tank 16 The liquid 14 is transferred from the container 12 to the tank 16 by being discharged toward the supply port 1604.
As the liquid level of the liquid 14 inside the container 12 decreases with the discharge of the liquid 14, the inside of the container 12 becomes a negative pressure, so that air is guided into the container 12 through the air introduction pipe 22 and the liquid 14 Efficient discharge.
Further, even if the liquid level of the liquid 14 inside the container 12 is located above the upper end 4602 of the inner pipe portion 46 located inside the container 12, the upper end 5002 of the outer pipe portion 50 is the upper end of the inner pipe portion 46. Since it is located above 4602, the liquid 14 is prevented from leaking from the outer pipe portion 50 to the outside of the container 12.
When most of the liquid 14 inside the container 12 eventually flows out and the discharge of the liquid 14 from the liquid discharge pipe portion 30 stops, the container 12 is grasped and the bottom wall 1202 side of the container 12 becomes high and the spout 1208 becomes low. The container 12 is tilted so as to be such that the rest of the liquid 14 in the container 12 is discharged from the liquid outflow jig 10 to the tank 16.
When the discharge of the liquid 14 is completed, the transfer work of the liquid 14 is completed.
Further, when the liquid 14 is transferred to the tank 16 using the new container 12, the container 12 placed on the container support jig 18 may be replaced and the same operation may be repeated.

According to this embodiment, air can be guided to the inside of the container 12 by the air introduction pipe 22 of the liquid outflow jig 10 attached to the spout 1208 of the container 12.
Therefore, when the liquid 14 is discharged, the inside of the container 12 becomes a negative pressure, so that air can enter the container 12 from the liquid discharge pipe portion 30 and the breathing phenomenon in which the discharge of the liquid 14 is hindered can be prevented. The liquid 14 can be efficiently discharged from the discharge pipe portion 30, which is advantageous in improving the efficiency of the transfer work of the liquid 14 in the container 12.
For example, comparing the time required to transfer 18 liters of liquid 14 from one container 12 to the tank 16, it took about 3 minutes when a conventional hand pump was used, but this embodiment When the liquid outflow jig 10 was used, the time could be shortened to less than 2 minutes, and a time reduction of about 40% was achieved.
Further, in the transfer work of filling the empty tank 16 with the liquid 14 of the container 12 for 7 or 8 containers, conventionally, the preparatory work, the transfer work of the liquid 14, and the post-cleaning work have been performed. The total time required for the work was about 1 hour, but when the liquid outflow jig 10 of the present embodiment was used, it could be shortened to about 30 minutes, and a time reduction of about 50% was achieved. ..
Further, since the on-off valve for liquid is provided, the liquid 14 does not inadvertently leak from the liquid discharge pipe portion 30, which is advantageous in improving the efficiency of the transfer work of the liquid 14 in the container 12. This is advantageous in preventing the liquid from being ejected when the container 12 falls over and ensuring safety during work.

Further, according to the present embodiment, since the air introduction pipe 22 is supported by the air introduction pipe attachment portion 28, it is advantageous in simplifying the support structure of the air introduction pipe 22.
Further, according to the present embodiment, with the spout attachment portion 26 attached to the spout 1208, the liquid discharge pipe portion 30 is directed downward and the air introduction pipe attachment portion 28 is directed upward. Therefore, it is advantageous in surely guiding air from the outside of the container 12 to the inside of the container 12, and it is advantageous in efficiently discharging the liquid 14 from the liquid discharge pipe portion 30, and the liquid 14 in the container 12 is advantageous. It will be more advantageous in improving the efficiency of the transfer work.

Further, according to the present embodiment, the connecting pipe portion 24 extends from the intermediate portion between the first pipe portion 2402 extending linearly and the extending direction of the first pipe portion 2402 to the first pipe portion 2402. Since it is configured to include the second pipe portion 2404 extending in the direction orthogonal to the direction, it is advantageous in simplifying the configuration of the connecting pipe portion 24.
Further, according to the present embodiment, the connecting tool 44 connecting the outer pipe portion 50 and the intermediate pipe portion 48 is provided with an air on-off valve. Therefore, if the air on-off valve is closed, the container 12 can be opened. Even when the posture of the container 12 is changed such as to lay it on its side, it is possible to prevent the liquid 14 in the container 12 from leaking from the outer pipe portion 50 to the outside of the container 12, which is advantageous in improving workability. In addition, it is advantageous in preventing the liquid from being ejected when the container 12 falls over and ensuring safety during work.

In the present embodiment, the case where the connector 44 is provided with an air on-off valve that is opened and closed by the lever 5804 has been described, but instead of the air on-off valve, the inside of the container 12 becomes a negative pressure. A check valve or the like that opens may be provided. In this case, it goes without saying that it is advantageous in preventing the liquid from being ejected when the container 12 falls and ensuring the safety during work, and the manual operation of the lever 5804 can be omitted, so that workability is possible. It will be even more advantageous in improving the above.
