Description

[Detailed explanation of the invention] This invention is designed to attach a cap that functions as an outer stopper to a bottle in a removable manner, and then turn the bottle upside down and return it to its original position. Even a relatively large amount of internal solution can be accurately measured and stored in the cap, and the measured liquid can be stored as is by removing the upper cap attached to the cap, or even when the cap is removed from the bottle. It is an object of the present invention to provide a liquid metering cap device that can be easily dispensed and used.

Conventionally, this type of device was
As described in the above publication, an inner stopper that fits tightly into the neck of a bottle of medicine, etc. is provided, the bottom of the inner stopper is raised upward in a conical shape, and a spout hole is provided at the top of the inner stopper. The body is inserted into the spout hole so as to be slidable up and down, and a spring holder having a locking portion at the top and a plug body at the bottom is provided, and a coil spring is inserted between the top of the spout hole and the locking portion. On the other hand, it is known that the outer cap that is screwed onto the neck of the bottle is provided with a pressing protrusion that comes into contact with the locking part of the spring holder to push down the stopper part and open a gap in the spouting hole. , the spout hole is made by protruding the bottom of the inner stopper fitted into the neck of the bottle upward in a conical shape, and drilling a hole in the top of the inner stopper, which is larger than the opening at the neck of the bottle. It is not possible to form a spout hole, and therefore a large amount of
Not only does it not allow quick dispensing, but it also requires multiple measurements to quantify a relatively large amount of solution that cannot be measured with the inner stopper, which is time-consuming and likely reduces accuracy. However, there was a problem in that it was not suitable for practical use in quantitatively measuring relatively large amounts of liquids that required rapidity or highly viscous liquids.

Therefore, the present invention provides a cap body 2, which serves as an outer stopper and is detachably attached to the outer periphery of the neck 1a forming the opening of the bottle 1, with a communication hole 3 that communicates with the opening with approximately the same diameter. , the communication hole 3
A wide liquid reservoir 4 with a shallow bottom is provided around the communication hole 3 and the liquid reservoir 4, and a cavity 5 having a larger capacity than the liquid reservoir 4 is provided above the communication hole 3 and the liquid reservoir 4. A spout 6 is provided above the communication hole 3 facing the communication hole 3, and a plate-shaped spout 6 is provided in the communication hole 3 that communicates with the opening of the bottle 1 so as to keep the communication hole 3 closed at all times. An on-off valve 7 having a valve portion 7a is provided, and an upper cap 8 is provided at the spout 6 of the cap body 2.
The upper cap 8 is provided with a valve operating member 9 that contacts the plate-shaped valve portion 7a to open the on-off valve 7 when attached and closes the on-off valve 7 when removed. The metering cap device allows a large amount of liquid to flow in and out at once through the communication hole 3, which communicates directly with the opening of the bottle containing the liquid, and allows the liquid to flow through the wide and shallow liquid around the communication hole 3. A relatively large amount of liquid that cannot be measured with an inner stopper or the like can be measured at once in the reservoir 4, and a plate-shaped valve part that is always closed when the upper cap 8 is removed from the spout 6. With the opening/closing valve 7, the cap body 2 can be used as it is for each bottle, or if the bottle is heavy, it can be removed from the bottle and the quantified liquid can be poured out. By freely attaching and detaching the cap bodies 2 of different capacities to the bottles and using them interchangeably, you can dispense large amounts of liquids with different capacities.
To provide a liquid metering cap device that can quickly and accurately meter liquid.

The present invention will be explained in detail with reference to the embodiments shown below. 1 is a bottle containing liquid A;
A cap body 2 serving as an outer stopper is screwed onto the outer circumferential threaded portion of the neck portion 1a forming the opening, and the cap body 2 is detachably attached to the bottle 1. The cap body 2 is provided with a communication hole 3 communicating with the opening of the bottle 1 with substantially the same diameter, and is also provided with a wide and shallow liquid reservoir 4 around the communication hole 3. Above the communication hole 3 and the liquid reservoir 4 is a liquid reservoir 4.
A cavity 5 with a larger capacity is formed, and a spout 6 is provided above the cavity 5 facing the communication hole 3. Further, an on-off valve 7 is integrally attached to the communication hole 3, and a valve operating member 9 protruding from the inside of the upper cap 8 attached to the spout 6 is connected to a plate-shaped valve portion of the on-off valve 7. It is provided so as to come into contact with 7a. The valve portion 7a of the on-off valve 7 is provided so as to normally close the communication hole 3, and is configured to open when the valve operating member 9 comes into contact with it and presses it.

Therefore, as shown in FIG. 2, when the bottle 1 is turned upside down with the cap body 2 attached to the bottle 1 and the upper cap 8 attached to the cap body 2, the valve operating member 9 opens and closes the bottle. Since the valve 7 is open, the liquid A in the bottle 1 will immediately flow into the empty chamber 5 through the communication hole 3.
Here, when the bottle 1 is returned to its original upright position as shown in the third figure, a certain amount of the liquid A in the empty chamber 5 of the cap body 2 quickly collects in the wide and shallow liquid reservoir 4. The remainder quickly returns into the bottle 1 through the open communication hole 3.

Therefore, as shown in the third figure, the upper cap 8 is removed from the cap body 2, the on-off valve 7 is closed, and the top cap 8 is removed together with the bottle 1 as shown in the fourth figure, or from the bottle 1 to the cap body 2 if the bottle 1 is heavy. By removing the cap body 2 and tilting the cap body 2, a certain amount of liquid A remaining in the liquid reservoir 4 can be poured into the spout 6.
This means that it can be taken out to the outside. At this time, if various types of cap bodies 2 with different capacities of the liquid reservoirs 4 are prepared, and these are detachably attached to the bottle 1 and used interchangeably, it is possible to quantify liquids of various capacities. Become.

As described above, according to the liquid metering cap device according to the present invention, the neck portion 1 forming the opening of the bottle 1
The cap body 2, which serves as an outer plug and is detachably attached to the outer periphery of the cap, is provided with a communication hole 3 that communicates with the opening with approximately the same diameter, and a wide liquid reservoir with a shallow bottom is provided around the communication hole 3. A portion 4 is provided, and the communication hole 3
Above the liquid reservoir 4, a cavity 5 having a larger capacity than the liquid reservoir 4 is provided, and further above the cavity 5, a spout 6 is provided facing the communication hole 3. The communication hole 3 communicating with the opening of the bottle 1 is provided with a plate-shaped valve portion 7 positioned at a position where the communication hole 3 is always closed.
An on-off valve 7 is provided, and an upper cap 8 is removably attached to the spout 6 of the cap main body 2, and the upper cap 8 is provided with an on-off valve 7 that comes into contact with the plate-shaped valve portion 7a when attached. Since the structure includes a valve operation member 9 that opens the on-off valve 7 and closes the on-off valve 7 when the bottle is removed, the liquid once passes through the communication hole 3 that communicates directly with the opening of the bottle containing the liquid. A large amount of liquid can be taken in and out of the tank, and a relatively large amount of liquid that cannot be measured with an inner stopper etc. can be quickly determined at once in a wide and shallow liquid reservoir 4 around the communication hole 3. can, and furthermore,
When the upper cap 8 is removed from the spout 6, the on-off valve 7, which has a plate-shaped valve part that is always closed, allows
The quantified liquid can be poured out by leaving the cap body 2 as it is in the bottle, or by removing it from the bottle if it is heavy and tilting the cap body 2. By freely attaching and detaching cap bodies 2 of different capacities to bottles and using them interchangeably, liquids of different capacities can be determined quickly and accurately.
