Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for filling a container B such as a bottle with a liquid in a separately provided liquid tank A.

To transfer the liquid in liquid tank A to a container, it is sufficient to provide an outlet in liquid tank A and transfer the liquid from the outlet directly or through a rubber hose, etc.; Alternatively, a stopper is required at the end of the rubber hose to stop the liquid in the container before it becomes full, and even if such a stopper is provided, if the container is opaque, it is necessary to know how much liquid is in the container. The problem was that things were difficult and sometimes overflowing.

The present invention solves the above-mentioned drawbacks and relates to a device that can accurately transfer a desired amount into a container.
is suspended, and on the outer periphery of the liquid supply cylinder there is a lower bottom of a temporary liquid storage cylinder,
An outer tube 4 which is biased downward by a spring 3 wound between its upper end surfaces is disposed in a loose state, and has a diameter at least larger than the diameter of the outer tube 4 on the outer periphery of the lower end of the liquid supply cylinder 2. ○ ring 5
At the same time, a liquid outlet hole 6 is provided in the wall of the liquid supply cylinder just above the O ring, and the lower closed part 8 of the air vent thin tube 7 inserted into the liquid supply cylinder 2 is inserted from the O ring. The upper liquid supply cylinder wall is opened to the outside, and the upper opening □ part 9 is opened to the upper space inside the temporary liquid storage cylinder, and a brim-like member made of a sacrificial material such as rubber or sponge is attached to the outer periphery of the outer pipe. 10 is attached so that the flanged body 10 is temporarily fixed at an arbitrary position on the outer tube 4 circumferential wall due to the frictional resistance between the central hole of the golden body and the outer tube 4 circumferential wall, and the collar attached to the upper surface of the golden body The peripheral part of the flat plate 11 and the peripheral part of the lower surface of the flanged body 10 are
The upper limit position of the movement of the flanged body 10 is adjusted around the outer cylinder 4 and above the flanged flat plate 11. A plurality of adjusting rings 19 each having a different thickness are arranged in a free iron shape as a member for adjusting the temperature, and a float chamber 14 is installed above the liquid rising pipe 13 extending upward from the upper bottom of the temporary liquid storage tank. The upper entrance part 16 of the float chamber is closed and opened by the floating and sinking of the float 15 inserted into the float chamber, and the liquid is placed in the lower part of the temporary liquid storage cylinder or at a required part outside the liquid supply cylinder. This is a liquid quantitative filling device characterized by having a supply row 7 for replenishment.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings.

A separately arranged liquid tank A has a fusible hose 18.
The tank A is in communication with the liquid replenishment supply row 7 of the liquid filler main body C, and the liquid in the tank A is temporarily stored in the liquid temporary storage cylinder 1.

When filling the liquid into the container B, the lower end of the liquid supply cylinder 2 is sequentially inserted from the upper opening of the liquid container B, and even when the upper opening of the liquid container hits the lower surface of the brim-shaped body 10, the liquid filling device main body still remains. When C is pressed against the liquid container, the upper opening of the liquid container deforms the brim 10 and further compresses the spring 3, causing the outer tube 4 to move upward, opening the liquid outlet hole 6, and opening the air vent tube 7.
The lower opening □ 8 is also opened, and the liquid stored in the liquid tank A flows down the liquid supply cylinder 2 from the hose 18 through the liquid replenishment supply port 17 and from the liquid spout hole 6 to the liquid container B.
The air inside the container rises through the air vent thin tube 7 and is sent into the temporary liquid reservoir 1.

In this way, the liquid is stored in the container B, and when the liquid level reaches the lower entrance 8 of the air venting tube 7, there is no way for the air to escape beyond that point, so the liquid rises inside the air venting tube 7, and the liquid rises. The pressure stops at the point where the pressure is harmonized with the air chamber D in the temporary storage cylinder 1, and no further liquid flows down.

If the water level of the liquid tank A is lower than the lower end of the liquid rising pipe 13, the liquid in the air vent pipe 7 stops rising at the same water level as that of the tank A.

When the water level in the liquid tank A becomes higher than the lower end of the liquid riser 13, the liquid rises through the liquid riser 13.

At this time, the pressure in the air chamber D is equal to the pressure difference between the water level in the liquid tank A and the water level in the temporary liquid storage tank 1, so the liquid in the air vent pipe 7 is equal to the water level in the temporary liquid storage tank. It stops at water level. The liquid riser pipe 13 does not require any special structure when the upper closing part 16 closes at a position higher than the water level of the liquid tank A, but a float is installed above the liquid riser pipe 13 in order to make the filling device main body C compact. A chamber 14 is formed and a float 15, which is inserted into the chamber so as to be able to move up and down, floats and sinks, thereby closing and opening an upper entrance portion 16 to limit the rise of the liquid.

After that, when the liquid filler main body C is pulled up, the spring 3
With this force, the outer tube 4 slides downward, and both the liquid discharge hole 6 and the lower entrance part 8 of the air vent tube 7 are closed, and filling of the liquid is completed.

In this case, the amount of liquid put into the liquid container is determined by the depth at which the lower entrance part 8 of the air vent thin tube 7 is inserted into the liquid container, so the amount can be changed arbitrarily by adjusting the height of the golden body 10. It is something that can be done.

In order to adjust the height of the maxim body 10, it is recommended that a plurality of height adjustment rings 19 made of plastic or the like, each having a different thickness, be fitted with iron and their number adjusted as appropriate. . Since there is a binding device 12 in the brim, the lower opening 8 of the air vent tube 7 closes before the liquid supply tube 2 is completely removed from the container, as shown in FIG. Since the container is lowered, the upper space of the container becomes negative pressure, and in the case of a lightweight container, there is no possibility that the container will stick to the flanges and be lifted up. Since the container is bound by a binding device 12 at its peripheral edge, the container is turned over from the binding part, and a small gap is created between the container and the flanged body 10, through which air can flow in. However, since there is no negative pressure in the upper space of the container, there is no problem such as the container being raised.

Considering this point, a small thick and small diameter ring as shown in the figure 21 is arranged between the flanged flat plate 11 and the flanged body 10, and the flanged body 1
If the container is installed in a slightly tilted position, it will be more effective to prevent the container from rising. As described above, the present invention has the effect that liquid can be filled with a certain distance from the mouth of the container with a simple operation, regardless of the shape of the container, whether it is transparent or opaque. .
