In this embodiment, the first lid body 47 and the second lid body 49 are each configured to open and close in a hinged manner, but as long as they are configured to open and close the first discharge hole 46 to the second discharge hole 48, respectively. , its structure or format can be changed in various ways.

Next, a procedure for discharging a predetermined amount of the content liquid L from the metered dispensing container 1 having the above configuration will be explained.

First, the content liquid L is filled into the inside of the container body 10 through the mouth part 11. Next, the closing body 40 is assembled to the measuring member 30 to constitute the metered discharge cap 20, and then the mounting part 41 is screwed into the mouth part 11. The fixed amount dispensing cap 20 is assembled to the container body 10 by coupling. Thereby, the fixed amount dispensing container 1 is in a state filled with the liquid content L as shown in FIG.

Next, as shown in FIG. 4, the fixed amount dispensing container 1 is placed in an inverted position. When the fixed amount dispensing container 1 is placed in an inverted position, the liquid content L stored in the container body 10 passes through the flow path between the first side wall portion 33 and the second side wall portion 35 and reaches the first section of the metering member 30. It flows into the storage space S1 between the wall part 44 and the second partition wall part 45.

Here, when the liquid level of the content liquid L that has flowed into the storage space S1 reaches the upper end (lower end in FIG. 4) of the first side wall portion 33, the air inside the first measuring chamber 36 and the first discharge space S2 is Since it cannot flow toward the inside of the container body 10, the liquid level of the content liquid L that has flowed into the storage space S1 on the first measuring chamber 36 side is at the upper end (lower end in FIG. 4) of the first side wall portion 33. maintained in position.

On the other hand, when the fixed amount dispensing container 1 is in an inverted position, the upper end (lower end in FIG. 4) of the second side wall 35 is located higher than the upper end (lower end in FIG. 4) of the first side wall 33. , the liquid level of the content liquid L on the side of the second measuring chamber 37 reaches the upper end (lower end in FIG. 4) of the second side wall 35 above the upper end of the first side wall 33; Since the air inside the chamber 37 and the second discharge space S3 cannot flow toward the inside of the container body 10, the liquid level on the second measuring chamber 37 side of the content liquid L that has flowed into the storage space S1 is It is maintained at the upper end (lower end in FIG. 4) of the second side wall portion 35.

In this manner, when the fixed-quantity dispensing container 1 is placed in an inverted position, more liquid L is filled on the second measuring chamber 37 side of the storage space S1 than on the first measuring chamber 36 side.

Next, as shown in FIG. 5, the fixed amount dispensing container 1 is returned from the inverted state shown in FIG. 4 to the upright state. When the fixed amount dispensing container 1 returns to the upright state, the liquid content L inside the storage space S1 flows into the first measuring chamber 36 from between the first side wall 33 and the first partition wall 44, and It flows into the inside of the second measuring chamber 37 from between the second side wall portion 35 and the second partition wall portion 45 . At this time, when the fixed amount dispensing container 1 is in an inverted state, the second measuring chamber 37 side of the storage space S1 is filled with more content liquid L than the first measuring chamber 36 side, so when returning to the upright state, , more content liquid L flows into the second measuring chamber 37 than into the first measuring chamber 36. In this embodiment, when the metered dispensing container 1 is in an inverted state, the storage space S1 is filled with 35 ml of the liquid content L, and when it is returned to the upright state, 15 ml of the liquid content L is transferred from the storage space S1 to the first measuring chamber 36. The dimensions of each part are set so that 20 ml of the content liquid L flows into the second measuring chamber 37 from the storage space S1.

In this way, by placing the fixed amount dispensing container 1 in the inverted position and then returning it to the upright position, the first measuring chamber 36 is filled with a predetermined amount of the content liquid L, and the second measuring chamber 37 is filled with the first measuring chamber. A predetermined amount of content liquid L greater than 36 can be filled.

Next, the lid body (first lid body 47 or The second lid 49) is opened, and the metered amount discharge container 1 is tilted so that the first discharge hole 46 to the second discharge hole 48 face downward, and the content liquid L is discharged in a fixed amount.

For example, when discharging a small amount of liquid L filled in the first measuring chamber 36, as shown in FIG. 6, the first lid body 47 is opened to open the first discharge hole 46, In this state, the fixed amount dispensing container 1 is tilted so that the first discharge hole 46 is located below the second discharge hole 48 and the first discharge hole 46 faces downward. As a result, a predetermined amount of the content liquid L measured by the first metering chamber 36 reaches the first discharge hole 46 through the first discharge space S2, and is discharged from the first discharge hole 46 to the outside.

On the other hand, when discharging a large amount of liquid L filled in the second measuring chamber 37, as shown in FIG. 7, the second lid body 49 is opened to open the second discharge hole 48. In this state, the fixed amount dispensing container 1 is tilted so that the second discharge hole 48 is located below the first discharge hole 46 and the second discharge hole 48 faces downward. As a result, a predetermined amount of the content liquid L measured by the second metering chamber 37 reaches the second discharge hole 48 through the second discharge space S3, and is discharged from the second discharge hole 48 to the outside.

Further, as shown in FIGS. 6 and 7, when the metered dispensing container 1 is tilted in order to discharge the content L to the outside from the first discharge hole 46 or the second discharge hole 48, the content inside the container body 10 L flows into the storage space S1. As a result, after all the liquid content L inside the first measuring chamber 36 or the second measuring chamber 37 is discharged to the outside from the first discharge hole 46 or the second discharge hole 48, the metered discharge container 1 is returned to the upright position. Then, the first measuring chamber 36 and the second measuring chamber 37 are each filled with a predetermined amount of the content liquid L for the next discharge. Therefore, once the content liquid L has been discharged, there is no need to return the metered dose dispensing container 1 to the upright position and then turn the metered dose discharge container 1 into the inverted position again to fill the storage space S1 with the content liquid L. The next quantitative discharge of the content liquid L can be easily performed.

As described above, according to the metered discharge container 1 or the metered discharge cap 20 of the present embodiment, the liquid content L stored in the container body 10 can be transferred to the metered discharge container 10 without removing the metered discharge cap 20 from the container body 10. A fixed amount can be easily discharged by simply changing the direction of the liquid and opening the first lid 47 or the second lid 49.

Further, according to the fixed amount dispensing container 1 or the fixed amount dispensing cap 20 of the present embodiment, the closure body 40 is integrally connected to the outer peripheral edge of the top wall portion 43, and the mounting portion 41 is integrally provided on the outer peripheral surface. Since the upper cylindrical part 42 is coaxial with the side cylindrical part 31, and the upper cylindrical part 42 is fitted to the upper end of the lower cylindrical part 31, the fixed amount dispensing cap 20 can be placed inside the upper cylindrical part 42. The cost of the fixed amount dispensing container 1 or the fixed amount dispensing cap 20 can be reduced by having a structure that can accommodate a certain amount of the liquid content L and also allowing the fixed amount dispensing cap 20 to be easily formed.

Furthermore, according to the metered discharge container 1 or the metered discharge cap 20 of the present embodiment, the lower cylindrical portion 31, the first bottom wall portion 32, the first side wall portion 33, the second bottom wall portion 34, and the second side wall portion 35 is integrally formed to constitute the metering member 30, the metering member 30 can be easily formed by injection molding of a synthetic resin material, and the cost of the metering dispensing container 1 or metering dispensing cap 20 is reduced. can do.

As shown in FIGS. 6 and 7, when tilting the fixed amount dispensing container 1 in order to discharge the content L from the first discharge hole 46 to the second discharge hole 48, the tilt of the fixed amount dispensing container 1 (the fixed amount If the angle between the axis O of the container 1 and the horizontal direction is too small, the liquid level of the liquid content L flowing into the storage space S1 from the inside of the container body 10 will be lower than the first partition wall 44 or the second partition wall. The lower end of the portion 45 (the end facing upward in FIGS. 6 and 7) is exceeded, and as a result, the content liquid L inside the storage space S1 is sequentially replaced with air and continuously discharged to the outside, causing the content to be lost. It becomes impossible to discharge a fixed amount of liquid L.

On the other hand, in the quantitative dispensing container 1 or the metering dispensing cap 20 of the present embodiment, the distance in the radial direction perpendicular to the axis O between the upper end of the first side wall portion 33 and the first partition wall portion 44 is defined as the distance A1. , the distance in the direction along the axis O between the upper end of the first side wall part 33 and the lower end of the first partition wall part 44 is defined as distance B1, and the distance between the upper end of the second side wall part 35 and the second partition wall part 45 When the distance in the radial direction perpendicular to the axis O of The positions of the first side wall 33, first partition wall 44, second side wall 35, and second partition wall 45 are such that B1 is three times or more the distance A1, and distance B2 is three times or more the distance A2. Or set the dimensions.

With such a configuration, as shown in FIGS. 6 and 7, when the liquid content L is discharged to the outside from the first discharge hole 46 or the second discharge hole 48, the inclination of the quantitative discharge container 1 is approximately 20 degrees or more. If so, the liquid level of the content liquid L that has flowed from the inside of the container body 10 into the storage space S1 is at the lower end of the first partition wall 44 or the second partition wall 45 (facing upward in FIGS. 6 and 7). Since the content liquid L does not exceed the end portion), the content liquid L can be stably discharged at a fixed amount.

The present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the gist thereof.

For example, in the embodiment described above, the mounting portion 41 is configured to be attached to the mouth portion 11 by screw connection, but it may be configured to be attached to the mouth portion 11 by plugging.

Further, the closure body 40 may not include the upper cylindrical portion 42 and may have a configuration in which the top wall portion 43 directly closes the upper end of the lower cylindrical portion 31 . In this case, the dimensions of each part are adjusted so that the first measuring chamber 36, the second measuring chamber 37, the storage space S1, the first discharge space S2, and the second discharge space S3 having the desired volumes are formed inside the metering member 30. is set.
