[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid transport and storage container which is provided with a mechanism for discharging the stored and stored liquid and prevents the liquid from flowing out to the outside when the liquid falls.

[0002]

2. Description of the Related Art Generally, a container for transporting and storing a relatively small amount of liquid seasoning such as drinking water for outdoor use or soy sauce for business use, or household kerosene (hereinafter referred to as a carrying container). Is often used as a plastic can body such as polypropylene. To take out the liquid contained and stored in such a carrying container, as shown in FIG. 5, a hose 1 with a beak tube for taking out is attached and used in combination with a funnel 2, or As shown in 6, an auxiliary pump 3 for pumping
Is used.

[0003]

However, in such a conventional method, as described below, the liquid drips, overflows, or spills when it is taken out, which is not convenient in terms of handling. It was Taking as an example a kerosene transport and storage container, the disadvantages of refueling a domestic petroleum stove from this container will be described.

There are two types of recent household petroleum stoves, one in which the kerosene storage tank 4 is integrated with the burning portion and the other in which the kerosene storage tank 4 is detachably mounted in the burning portion. In the stove as well, the diameter of the inlet of the storage tank 4 was smaller than the diameter of the take-out hose 1 equipped in the commercially available carrying container 5 (transportation storage container), and it was often not fitted. Therefore, when refueling such a kerosene storage tank 4, as shown in FIG.
A method is used in which one person holds the funnel 2 in the inlet of the storage tank 4 and holds it, and the other person lifts and pours the carrying container 5, but this method has a large storage amount of kerosene 6 in the carrying container 5. In some cases, the work requires a heavy and unreasonable posture, and especially in an aged household, it is difficult. Further, since the outflow amount of the kerosene 6 largely varies depending on the angle at which the carrying container 5 is tilted, the kerosene 6 is often tilted at a large angle to cause overflow, which causes inconveniences such as dirty hands and unpleasant odors, and the funnel 2 It was difficult to refuel by myself because it was necessary to support the car, which hindered daily life.

Under these circumstances, when the refueling operation of the kerosene 6 is performed by one person, it is now common to use the auxiliary pump 3 for pumping, as shown in FIG.

However, when the auxiliary pump 3 is used, the kerosene suction portion 7 of the auxiliary pump 3 is immersed in the kerosene 6 in the carrying container 5, and the operation mechanism of the auxiliary pump 3 is based on the siphon principle. Therefore, kerosene 6 adheres to the inside of the suction section 7 and the discharge section 8. Then, the auxiliary pump 3 dripped or spilled the kerosene 6 in the vicinity of the refueling work location, and the hand was contaminated, and an unpleasant odor remained.

It is convenient to store the auxiliary pump 3 immediately near the storage place of the carrying container 5, but the auxiliary pump 3
Since the whole shape of is a slender rod shape and does not stand by itself, it is often stored while being inserted into the carrying container 5. However, since the inner diameter of the insertion port of the carrying container 5 is much larger than the outer diameter of the suction portion 7 of the auxiliary pump 3 and a large gap is formed between them, the kerosene 6 is discharged from this gap as the temperature rises. It was vaporized and polluted the air inside and outside, which had a negative effect on human life. Further, the storage of the kerosene 6 and the auxiliary pump 3 in such a carrying container 5 should be avoided when the carrying container 5 falls due to force majeure at the time of an earthquake or human causes such as carelessness of an operator. However, it was in a very dangerous situation such as the outflow of kerosene 6 and direct connection to a disaster such as a fire.

The present invention has been made in order to solve these problems, and one person can safely and simply perform the work of injecting and supplying the liquid to a desired receiving portion, and the outside of the container at the time of falling. An object of the present invention is to provide a liquid transport and storage container in which the liquid is prevented from flowing out.

[0009]

A liquid transporting and storing container according to the present invention has a liquid outlet and a liquid inlet with a detachable lid, each of which is a square container which can be carried. The main body and the inner side surface and the inner bottom surface of the container body are arranged so as to surround these surfaces, and one end is connected to the liquid outlet, and the other end is on the bottom of the container main body. An open guide pipe, an electric pump attached to the opening of the guide pipe for delivering or sucking a liquid into the pipe, a power source for driving the electric pump, and an electric pump for the electric pump. A switch for switching and stopping the operation and a liquid outlet hose that is detachably and liquid-tightly attached to the outside of the liquid outlet of the container body are provided, and the container body can be placed at any position in the vertical and horizontal directions. Even though the inside of the container body is surrounded Some of disposed the diversion pipe with at a higher position than the liquid surface, after the liquid delivery, liquid and wherein the characteristics and Sururu stopping sucked to the electric pump.

[0010]

In the liquid carrying and storing container of the present invention, when the liquid contained and stored in the container body is to be injected and supplied to a desired container, first, the liquid inlet provided on the upper part of the container body is attached and detached. The possible lid is loosened and the inlet is partially opened. In this way, after the necessary amount of air can be replenished into the container body through the inlet, the end of the outlet hose attached to the liquid outlet is inserted into the injection receiving portion of the container to be injected / supplied, The switch is turned on to drive the electric pump. Then, by this electric pump, the liquid contained in the container body is pushed out from the outlet port of the upper portion of the container body through the flow pipe, and is injected / supplied from the tip portion thereof through the outlet hose. After the injection is completed, the operation of the electric pump is switched by the switch, and the liquid filled in the outlet hose, etc. is sucked into the flow guide pipe and takes a stable liquid level position, and the tip of the outlet hose. Liquid dripping or spilling from the etc. is completely prevented. Further, thereafter, by closing the movable plug of the liquid charging port to close the charging port, the inflow of air into the container body can be completely suppressed.
In this state, even if the container falls, there is a sufficient amount of air in the guide pipe and the inside of the guide pipe is not filled with liquid to a high position, so the liquid flows out from the outlet hose. There is nothing to do.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of an essential part of a transportation and storage container having a kerosene supply mechanism according to an embodiment of the present invention, and FIG. 2 is a perspective view schematically showing a state after refueling.

In the figure, reference numeral 9 indicates a rectangular container body made of plastic such as polypropylene and containing and storing kerosene 10 therein, and 9'indicates a joint portion in which an upper portion and a lower portion of the container body 9 are joined. . On the upper surface of the container body 9, an injection port 11 for inputting kerosene 10 from a larger-capacity storage tank and a discharge port 12 to which a discharge hose described later is connected are integrally formed. And
A lid 1 is provided on the outer circumference of each of the inlet 11 and the outlet 12.
3 and 14 are screwed together, and by rotating these lids 13 and 14 in the closing direction, the respective openings can be completely closed and the inside of the container body 9 can be liquid-tightly and airtightly sealed. Is configured. Further, reference numeral 15 denotes a flow guide pipe formed of the same plastic material as the container body 9, which, as shown in FIG. 2, is in contact with one side surface and bottom surface of the container body 9 and has these surfaces connected to each other. It is arranged so as to be bent so as to surround it. And this diversion pipe 1
One end of 5 is connected to the opening of the outlet 12 to the container body 9 from the inside, and the other end is opened to the inner bottom of the container body 9. Further, reference numeral 16 denotes an electric pump fixedly arranged on the inner bottom portion of the container body 9, which is attached to an open end portion of the diversion pipe 15 which is opened at the inner bottom portion, so that the motor rotates the propeller (normal Direction or the reverse direction), the kerosene 10 is delivered or sucked into the flow pipe 15. Further, reference numeral 17 denotes a dry battery which is attached to the outer peripheral surface of the upper part of the container body 9 and rotationally drives the motor of the electric pump 16. As a power source for the electric pump 16, a storage battery, a commercial AC power source, or the like can be used in addition to the dry battery. Further, reference numeral 18 denotes a lead-out hose made of plastic such as polypropylene and having a bellows formed on the outer periphery and configured to be flexible (flexible), and an injection end portion of the tip thereof is inserted into a kerosene tank of an oil stove or the like. It is formed in a beak shape so that the outer diameter is smaller than the inner diameter of the injection receiving portion of the kerosene tank. Further, reference numeral 19
Shows a connection chuck which is fitted on the outer periphery of the base end of the lead-out hose 18 and which is detachably and liquid-tightly attached to the lead-out port 12 of the container body 9. Furthermore, reference numeral 20 denotes a switch mounted near the injection end of the lead-out hose 18, which switches the current direction from the dry battery 17 to the electric pump 16 and shuts off the electric current, thereby operating the electric pump 16 in the reverse direction. Start and stop. Further, reference numeral 21 indicates a handle integrally formed on the upper part of the container body 9 for carrying and the like.

Next, the operation of injecting and supplying the kerosene 10 using the kerosene transporting and storing container having the above structure will be described.

First, in order to put kerosene 10 into the container body 9, the lid 13 screwed into the introduction port 11 is rotated and removed, and the kerosene 10 is put into the container body 9 through the opening port 11 thus opened. After charging, the lid 13 is attached again. After that, when the container needs to be transported significantly, the lid 13 is further rotated to completely seal the inlet 11, and the lid 14 is similarly attached to the outlet 12.
The inflow and outflow of air and the outflow of kerosene in the container body 9 are prevented.

Next, in this way, the kerosene 10 is stored and
In order to inject and supply kerosene 10 from the stored transport storage container to a storage tank of a domestic oil stove, first loosen the lid 13 that closes the inlet 11 by turning it.
The container body 9 is replenished with the required amount of air through 1. Further, the base end of the outlet hose 18 is connected to the outlet 12 of the container body 9 via the connection chuck 19.
Then, the inlet end of the outlet hose 18 is inserted into the inlet port of the storage tank and supported by hand. In this state, the switch 20 is inserted in the kerosene outflow direction, and the motor of the electric pump 16 is rotated in the forward direction. Thus, the kerosene 10 housed and stored in the container body 9 by the delivery of the electric pump 16 is shown in FIG.
In the direction indicated by the arrow A, and is injected into the kerosene tank from the injection end of the outlet hose 18 through the flow pipe 15 and the outlet 12.

Immediately after the injection is completed in this way, the switch 20 is immediately put in the reverse direction (inflow direction) to rotate the motor of the electric pump 16 in the reverse direction, and then the switch 20 is returned to the stop position. The operation of the electric pump 16 is stopped. By operating and stopping the electric pump 16 as described above, as shown in FIG. 2, the kerosene 10 filled in the outlet hose 18 and the connection chuck 19 flows in the direction indicated by the arrow B in FIG. The liquid level of the kerosene 10 in the pipe 15 once retreats to the position of the electric pump 16,
The liquid level in the container body 9 is stable at the same height as the liquid level b. In addition, (b) is the position of the liquid level in the container body 9 after the kerosene 10 is injected into the storage tank of the oil stove. In this way, the kerosene 10 can be refueled without dripping, overflowing, spilling, or the like from the injection end of the outlet hose 18.

After that, the lid 13 is rotated in the closing direction to the end so as to close the charging port 11 and suppress the inflow of air into the container body 9, so that the discharging hose 18 is attached to the discharging port 12. Even in the state, it is possible to prevent the kerosene 10 from flowing out when the container falls.

Prevention of kerosene outflow at the time of tipping is performed by the following mechanism. That is, after the injection of the kerosene 10 into the storage tank is completed, the motor of the electric pump 16 is rotated in the reverse direction so that the outlet hose 18 and the connection chuck 1 are connected.
The kerosene 10 filled in 9 flows into the guide pipe 15 and is further sucked in the guide pipe 15 in the direction of the electric pump 16. However, the electric pump 16 is a blocking pressure feed type pump. Therefore, when the position of the liquid surface of the kerosene 10 in the flow pipe 15 exceeds the electric pump 16, the pump idles and the suction is stopped. Then, when the electric pump 16 is stopped in this way, the atmospheric pressure applied to the inside of the flow guiding pipe 15 through the injection end of the outlet hose 18 and the atmospheric pressure applied to the inside of the container body 9 through the opening 11 which is partially opened. The liquid level of kerosene 10 in the diversion pipe 15 is stable at the same level as the liquid level b of kerosene 10 in the container body 9 because the pressure is balanced with the atmospheric pressure. Next, after completely closing the inlet 11 with the lid 13, the kerosene 10 in the diversion pipe 15 is always exposed to the atmospheric pressure through the injection end of the outlet hose 18, but the kerosene 10 in the container body 9 does not. Also, equal pressure is applied by the enclosed air, and the liquid levels a and b of the kerosene 10 in the container body 9 and the diversion pipe 15 do not change. Then, in such a state, when the container is tumbled as shown in FIG. 3 or FIG. 4, the guide pipe 15 contacts the inner side surface and the inner bottom surface of the container body 9 so as to surround these surfaces. Since it is provided, no matter which side surface falls down, part of the flow guiding pipe 15 is located at a position higher than the liquid level b of the kerosene 10 in the container body 9. Since the kerosene 10 is not filled in that portion of the flow pipe 15, the force (according to the siphon principle) for pushing out the kerosene 10 in the outflow direction (the direction indicated by the arrow A in FIG. 1) is It does not take. Therefore, when the container falls, the kerosene 10 does not flow out from the outlet 12 through the outlet hose 18.

[0019]

As described above, according to the liquid transporting and storing container with the discharging mechanism of the present invention, it is safe for one person to inject and supply the liquid stored and stored in the container to the storage tank. And it can be performed easily. In addition, the liquid is completely prevented from flowing out of the container when it falls, and the occurrence of an accident that directly leads to a disaster such as environmental pollution or fire is prevented.
