Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid spout attachment for attaching a liquid spout used for filling oil from an oil container to an oil tank of a stove, for example, to a mouth hole of an oil container.

Conventionally, a household liquid pourer used for transferring oil has a suction pipe 21 connected to a pump section connected to a mouth hole 82 of an oil container 8, and a discharge pipe 22 connected to a stove oil as shown in FIG. It is inserted into the tank 17, the stopper 37 of the pump part 3 is closed, and the pump part 3 is pressed repeatedly to fill the oil with oil. After filling a predetermined amount of oil, the discharge pipe 22 is pulled out from the oil container 8 and the oil is removed from the container. If the mouth hole 82 of the container was not tightly sealed, the oil in the container would vaporize and become thinner, and the area around the container would be filled with petroleum gas, giving off a foul odor and posing a risk of catching fire.

Therefore, for example, Utility Model No. 45121, 1973, and Utility Model Number 45121,
No. 35479, the suction pipe of the liquid dispenser is inserted through the cap screwed into the mouth hole of the container to eliminate the gap between the mouth hole of the container and the suction pipe, thereby reducing the loss of oil due to vaporization. It has also been proposed to draw

However, when using the above-mentioned cap, the suction pipe will always be supported in an inclined state if the mouth hole of the container is diagonal, that is, the mouth hole opens on the slope of the container. As a result, there is a problem in that when the oil level drops, it becomes impossible to suck up the oil, and in the past, the container had to be tilted.

The technical problem to be solved by the present invention is to prevent the loss of oil content due to vaporization, and also to allow the suction pipe to bend to the bottom of the container even if the oil level drops.

In order to solve the above-mentioned technical problems, the present invention provides a sphere that is freely rotatable in a cylindrical body that has a fitting part that is to be tightly and removably fitted into the mouth hole of a liquid container, and in which the liquid is injected into the sphere. A through hole is provided to connect the suction pipe of the extractor.

The suction pipe of the liquid dispenser can be installed in the mouth hole of the oil container in a liquid-tight manner to prevent wear due to vaporization of the liquid, and since it is supported by the suction tube sphere and can tilt freely, the mouth hole of the container can be easily attached. Irrespective of the inclination, the dispenser is in an upright position, that is, liquid at the bottom of the container can be sucked up.

The present invention will be specifically described below based on embodiments shown in the drawings.

FIG. 1 shows the liquid dispenser 2 attached to a container 8 using the fitting 5 of the present invention, and the mouth hole 82 of the container 8 is provided in an inclined wall 81.

The spout 2 is a well-known one, and is entirely made of flexible synthetic resin, and the pump part 3 has a connecting pipe 32 having a suction port 33 and a discharge port 34 inserted into a drum-shaped hollow expansion/contraction body 31. A tongue-shaped valve plate 35 that opens only inwardly is fixed to the suction port 33, and a tongue-shaped valve plate 36 that opens only outwardly is fixed to the discharge port 34.
3.34 suction pipe 21. The discharge pipe 22 is connected.

The discharge tube 22 is formed into a bellows shape at the proximal end and central portion to further improve flexibility.

A receiving piece 4 having a receiving part 41 into which the distal end of the discharge pipe 22 is fitted is fitted into the suction pipe 21 .

The receiving piece 4 has a thick disk shape made of synthetic resin, and has a through hole 42 into which the suction pipe 21 is tightly fitted in an eccentric position.
At the same time, a hole into which the tip of the discharge pipe 22 fits is formed on the peripheral surface of the receiving piece on the opposite side of the throttle hole 42 so as not to intersect with the through hole 42, thereby forming a receiving part 41.

Further, a pipe 43 is inserted from the lower surface of the receiving piece 4 to communicate with the inner part of the receiving part 41, and the other end of the pipe 43 is hung down and fitted into the spherical body 6 of the fixture 5.

The fixture 5 is entirely made of synthetic resin, and has a suction pipe 21 in the center.
The cylindrical body 7 includes a sphere 6 having a through hole 61 into which the sphere 6 is tightly fitted, and a cylinder 7 which rotatably and tiltably supports the sphere 6 and has a fitting part 70 into the mouth hole 82 of the container 8.

A relief groove 62 is formed in the vertical direction in the through hole 61 of the sphere 6, and the lower end of the pipe 43 hanging from the receiving piece 4 is fitted into the receiving part 41 of the receiving piece 4. A return passage 60 communicating with the pipe 43 and the relief groove 62 is configured.

The cylinder 7 has a double structure in which an inner cylinder 71 is fitted into an outer cylinder 72, and the inner cylinder 71 has an inner surface formed into an arcuate surface 13 corresponding to the sphere 6, and the arcuate surface 73 seals the sphere 6 in a liquid-tight manner. and is slidably held.

A short peripheral wall 74 is protruded from the lower surface of the inner cylinder 71, and this peripheral wall 74 corresponds to the mouth hole of a metal can widely used as a container for petroleum and other liquids. It can be used by tightly pressing it into the hole.

The outer periphery of the outer cylinder 12 forms a fitting part 70 that tightly fits into a threaded cylinder 83 protruding outward from the periphery of the mouth hole 82 of the container 8, and a flange 75 protruding from the upper end that corresponds to the end face of the threaded cylinder 83. are doing.

The cap 64 that is screwed into the screw tube 83 has a receiving piece 4 in the center.
A circular hole 85 is opened that is larger in diameter than the flange diameter of the outer cylinder 12 and smaller than the flange diameter of the outer cylinder 12, and the flange 15 of the outer cylinder 72 is pressed with the peripheral edge of the throttle hole 85.

A cutoff valve 1 is attached to the tip of the discharge pipe 22 of the liquid ejector described above, and an insertion tube 16 that can be inserted into the receiving part 41 of the receiving piece 4 projects from the tip of the throttle valve 1.

Then, fit the fitting 5 into the mouth hole 82 of the container 8, and close the cap 8.
Fix it at 4.

Insert the suction pipe 21 of the spout 2 into the through hole 61 of the sphere 6 of the fixture 5.

Next, press the hollow expansion/contraction body 31 of the pump part 3, and
The two tongue-shaped valve plates 35 and 36 provided at the discharge port 34 are alternately opened and closed, and the liquid in the container 1 is sucked up by the vacuum action generated in the suction pipe 21, and the shutoff valve 1 is opened from the discharge pipe 22. It flows out through the inside of the valve seat 14.

Since the suction pipe 21 is supported by the sphere 6 which is rotatably and tiltably fitted into the cylinder 7 fixed to the container 8, the mouth hole 82 of the container 8 is connected to the inclined wall 81 as in this embodiment. Even if the suction pipe 21 is provided, the suction pipe 21 is positioned approximately vertically, that is, the suction pipe 21
Because the work can be done with the lower end of the container 8 close to the bottom of the container 8,
There is no need to tilt the container 8 even when the amount of liquid in the container 8 is small.

In addition, the space between the suction pipe 21 and the container mouth hole 82 is liquid-tightly closed by the fitting 5, and the suction pipe 21 is closed by the tongue-shaped valve plate 35, so that the spout 2 Even if a light device is set in the container, it is possible to prevent the liquid in the container 8 from depleting, and since the dispenser can be left alone with the dispenser attached to the container 8, there is no chance of losing the dispenser. This has the advantage that the next transfer operation can be carried out immediately.

When the predetermined amount of pouring work is completed, shut off valve 1 is closed, and shut off valve 1 is closed.
Fit the insertion pipe 16 into the receiving part 41 of the receiving piece 4, and turn the knob 93 of the shutoff valve 1 to open the valve body 9.

The liquid filling the discharge pipe 22 drips into the container 8 through the return passage 60 passing through the pipe 43 communicating with the receiving part 41 and the escape groove 62 of the sphere 6, so that the liquid can be used without wasting anything.

The present invention includes the suction pipe 21 and the container mouth hole 12 of the dispenser as described above.
It is possible to seal the space between the container and the container liquid-tightly, thereby preventing loss of weight due to vaporization of the liquid in the container.

Further, even if the suction pipe 21 is formed into a straight cylindrical shape passing through the sphere 6 of the fitting 5 and the container mouth hole 12 is provided in the inclined wall of the container, the suction pipe 21 can be used vertically. from,
Since the tip of the suction tube 21 can be brought close to the bottom of the container, there is no need to tilt the container even when the amount of liquid is small, and it has excellent effects such as ease of use.
