Note that the container body 1 may be any container as long as it has a shape to which a dispensing cap can be attached, and may be made of any material such as synthetic resin, glass, or metal.

Next, a swinging operation using the above-mentioned swinging cap will be explained.
(Quantitative drawing operation)
As shown in FIG. 5(a), in order to perform a quantitative dispensing operation, the second lid body 17 is set to the open state, and the quantitative dispensing port 11b is opened (initial stage). Subsequently, as shown in FIG. 5(b), the container main body 1 with the dispensing cap attached is set in an inclined position with the dispensing opening 11b facing downward. Then, the contents P slide from the container body 1 onto the bottom wall 25a, the inclined surface 25b, and the partition plate 25c of the metering adjustment section 25 in this order, and enter the metering chamber through the notch hole 25d provided in the partition plate 25c. The contents P can be moved into 26.

By forming the notch hole 25d to have a predetermined size (vertical and horizontal dimensions), the amount of movement of the notch hole 25d is controlled so that a large amount of the contents P cannot be introduced into the micrometering part M in the metering chamber 26 at once. Limited. The amount of content P that can be moved to the micrometering section M at one time is determined by the opposing distance L1 between the pair of short side ribs 19a, the opposing distance L2 between the partition plate 18 and the partition plate 25c, and the height dimension of the short side ribs 19a. It is preset according to the That is, in the present invention, by setting these dimensions in advance, the content P that moves from the notch hole 25d into the micro-measuring section M is always a constant amount, so that the micro-measuring section M can be used. It is possible to minutely measure the contents P of the container (measurement stage).

In this embodiment, for example, the horizontal dimension of the notch hole 25d is set to 6 mm and the vertical dimension is set to 2.3 mm, and the opposing distance L1 of the pair of short side ribs 19a forming the micrometering part M is set to 6 mm. By setting the height dimension to 1 mm and the opposing distance L2 between the partition plate 18 and the partition plate 25c to 5 mm, the content P that can be measured in the micro-measuring section M is made into a micro amount (for example, about 0.3 g). However, these dimensions can be changed as appropriate according to the expected amount of content P to be dispensed in a quantitative dispensing operation to be described later.

Subsequently, as shown in FIG. 6(a), when the attitude of the container body 1 is returned from the inclined attitude to the upright attitude, the content P slides down the inclined surface 25b from the micromeasuring part M in the measuring chamber 26 and It moves into the temporary holding chamber 27 through the gap S (temporary holding stage). At the same time, the contents P remaining in the communication portion 22 can be returned into the container body 1.

Finally, as shown in FIG. 6(b), when the attitude of the container body 1 is again set from the upright attitude to the inclined attitude, the contents P are transferred from the temporary holding chamber 27 to the outside via the quantitative dispensing port 11b. Can be rolled out (rolling stage). Here, the amount of content P dispensed is the minute amount (approximately 0.3 g) weighed in the previous weighing step.
Also, at this time, as in the above-mentioned measuring step, the contents P are moved to the micro-measuring section M of the measuring chamber 26 through the notch hole 25d, are weighed, and are dispensed in the next dispensing step. .

(Weighing stage).
In this manner, in the quantitative dispensing operation, when the container body 1 with the dispensing cap attached is repeatedly changed between the upright posture and the tilted posture, each time the container body 1 is placed in the tilted posture, a minute amount (approximately 0. 3g) can be shaken out. Therefore, for example, if you want to shake out 0.6 g of content P, you only need to repeat the above operation twice, and if you want to shake out 0.9 g of content P, you need to repeat the above operation 3 times. That's fine. In other words, the desired dispense amount can be adjusted by the number of fixed dispense operations.

(Arbitrary amount drawing operation)
As shown in FIG. 7, after returning the second lid 17 to the closed state and setting the first lid 15 to the open state to open the dispenser opening 11a, the container body 1 is placed in an inclined position. Then, the contents P in the container body 1 move to the arbitrary amount dispensing port 11a via the communication portion 22, so that an arbitrary amount of the contents P can be dispensed via the arbitrary amount dispensing port 11a.

Although the structure of the present invention and its effects have been described above with reference to Examples, the embodiments of the present invention are not limited to the above-mentioned Examples.

For example, in the above embodiment, a configuration is shown that has both the arbitrary amount dispensing port 11a and the first lid 15 for dispensing an arbitrary amount, and the fixed amount dispensing port 11b and the second lid 17 for dispensing a fixed amount. However, the present invention is not limited to the above-mentioned embodiment, and may be configured to include only the fixed amount dispensing port 11b and the second lid 17 for dispensing a fixed amount.

Further, in the above embodiment, the case where both sides of the partition plate 18 are sandwiched between a pair of sandwiching plates 25e arranged on both sides has been described, but a configuration in which the pair of sandwiching plates 25e are not provided may also be used. good.

Further, in the above embodiment, the arbitrary amount dispensing port 11a is formed of one through hole, and the fixed amount dispensing port 11b is formed of a plurality of (seven in this embodiment)) through holes. The dispenser opening 11a may be formed with a plurality of through holes, and the quantitative dispenser opening 11b may be formed with one through hole.

The present invention can be applied to a wider range of applications, particularly in the field of dispensing caps that require dispensing of minute amounts of contents.
