Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a measuring and dispensing cap capable of measuring and dispensing a dispensed amount.

[Conventional technology]

Conventionally, there is a liquid metering and pouring device described in Japanese Utility Model Laid-Open No. 61-180955.

As shown in FIG. 5, the liquid metering and dispensing device described in this publication has a fixed tubular body 50 fitted and fixed to the mouth tubular portion 2 of a container 1, and the fixed tubular body 50 has a vertical direction. An elongated slanted hole 51 extending in the circumferential direction and inclined in the circumferential direction is provided, and the fixed cylindrical body 50
A movable cylindrical body 52 is rotatably fitted to the movable cylindrical body 52, a longitudinal elongated hole 53 is provided in the movable cylindrical body 52, and a measuring cylindrical body 55 is provided outside the movable cylindrical body 52 to form a measuring cylindrical chamber 56. It was formed.

Then, in order to pour out the content liquid of the container 1 with this liquid measuring and pour-out device, first, the movable cylindrical body 52 is rotated, and the through hole 54 which is the matching point of the elongated hole 53 and the slanted elongated hole 51 is formed. When the container 1 is set up to a desired height and then inverted, the internal solution in the container 1 flows into the measuring cylinder chamber 56 through the through hole 54, and the air in the measuring cylinder chamber 56 is removed. It flows into the container 1 through the through hole 54.

When the liquid flowing into the measuring cylinder chamber 56 reaches the position of the through hole 54, the flow of the liquid into the measuring cylinder chamber 56 is stopped.

Therefore, when the lid 58 is removed, the liquid into the measuring cylinder chamber 56 is poured out from the pouring port 57.

[Problems to be solved by the device]

The conventional liquid metering and pouring device shown in FIG.
By rotating, the amount of the liquid flowing into the measuring cylinder chamber 56 can be set to an arbitrary amount, which is convenient because an arbitrary amount of liquid can be measured and poured out.

However, the liquid measuring and dispensing device is
When the liquid in the container 1 starts to be poured out from the pouring port 57 and the liquid level in the measuring cylinder chamber 56 drops a little, the liquid in the container 1 flows into the measuring cylinder chamber 56 from the through hole 54, so that accurate measuring and pouring can be performed. Is difficult to do.

The present invention has been made in view of the above-mentioned matters, and an object thereof is to make it possible to accurately perform the metering and dispensing in a metering and dispensing container formed so that the amount of the measurable liquid can be changed.

I used a cap.

[Action]

In the present invention, when only the liquid in the cylindrical measuring chamber 28 is to be poured out, the arc-shaped opening / closing plate 37 is provided between the cylindrical measuring chamber 28 and the arc-shaped measuring chamber 27 as shown in FIG. 3 (A). When the container 1 is turned upside down by shutting off, the liquid in the container 1 flows from the inflow port 6 to the inflow cylinder 5
The air that flows into the inside of the inflow cylinder 5 flows from the communication hole 9 into the container 1
Flows into.

Next, when the container 1 is erected, the liquid in the inflow cylinder 5 flows into the cylindrical measuring chamber 28 from the pouring cylinder inflow port 35, and the remaining liquid returns from the communication hole 9 into the container 1. .

Then, when the container 1 is inverted again, the liquid in the cylindrical measuring chamber 28 is poured out from the pouring tube 33 to the outside.

At this time, the liquid in the container 1 flows into the inflow pipe 5 from the inflow port 6 and heads for the pouring pipe inflow port 35, but flows in as the liquid flows from the container 1 into the inflow pipe 5. From the cylinder 5 to the container 1
Since the air flowing in passes through the communication hole 9,
By forming the communication hole 9 small, the inflow of air is restricted, the inflow of the liquid from the container 1 into the inflow pipe 5 is also restricted, and the liquid flowing into the inflow pipe 5 is supplied to the pouring pipe inlet 35. By the time it reaches, the outflow of the liquid in the cylindrical measuring chamber 28 ends.

When the liquid in the cylindrical measuring chamber 28 and one arc-shaped measuring chamber 27 is to be poured out, the arc-shaped opening / closing plate 37 is turned to rotate the cylindrical measuring chamber 28 and one arc-shaped measuring chamber 27. And the third
As shown in FIG. 4B or FIG. 4, the pouring operation is performed by communicating with each other.

Similarly, as shown in FIG. 3 (C), the cylindrical measuring chamber 28 and all arc-shaped measuring chambers 27 are made to communicate with each other and the liquid in all the measuring chambers is poured out. In the case of the embodiment shown in FIG. 4, one arc-shaped measuring chamber 27 is closed and two arc-shaped measuring chambers 27 are
There is also a means for communicating with the cylindrical measuring chamber 28 to measure and dispense.
