The first guide cylinder 21 is, for example, liquid-tightly fitted to the second opening 3b to seal the second opening 3b. The second guide tube 22 is provided with an engagement protrusion 22a that engages (undercut fit) with the engagement protrusion 11 formed in the second opening 3b, and protrudes radially inward. Accordingly, the inner plug member 20 is attached to the second opening 3b. The second guide tube 22 extends upward from the second opening 3b.
The first guide tube 21 and the second guide tube 22 guide the movable inner plug 4 so as to be movable up and down. The communication opening 24 a is located in the mouth 3 of the container body 2 and is an opening that communicates the inside of the container body 2 and the inside of the movable inner plug 4.

  The movable inner stopper 4 is attached to the mouth portion 3 of the container body 2 via the inner stopper member 20, and a storage cylinder 30 disposed above the communication wall portion 24 of the inner stopper member 20, and the storage And a valve body 32 which is connected to the cylinder 30 via a connecting member 31 and which is disposed below the communication wall 24 and opens and closes the communication opening 24a.

  The storage cylinder 30 is disposed inside the first guide cylinder 21 and is disposed inside the first storage cylinder 35 and the second guide cylinder 22 that are guided by the first guide cylinder 21 so as to be movable up and down. The second storage cylinder 36 guided by the second guide cylinder 22 so as to be movable up and down, the upper end portion of the first storage cylinder 35 and the lower end portion of the second storage cylinder 36 are connected to each other and are in contact with the flange portion 23. And an annular stopper wall 37, and is formed in a multistage cylindrical shape.

  The upper end portion 36 a of the second storage cylinder 36 protrudes upward from the upper end portion of the second guide cylinder 22 and expands radially outward so as to have substantially the same diameter as the second guide cylinder 22. Then, the upper end opening edge of the upper end portion 36 a of the second storage cylinder 36 that has substantially the same diameter as the second guide cylinder 22 is in contact with the top wall portion 51 of the cap body 5.

The stopper wall 37 is in contact with the flange portion 23 of the inner plug member 20 as described above, and defines the lowest limit position of the storage cylinder 30 when pressed from the cap body 5. Further, the stopper wall 37 protrudes radially inward from the first storage cylinder 35. A coil spring 38, which is a biasing member that biases the entire movable inner plug 4 upward, is disposed in a compressed state between the radially inner end portion 37 a of the stopper wall 37 and the communication wall portion 24. .
The coil spring 38 is positioned in the radial direction, and is disposed in a state of being stably held between the radial inner end portion 37 a of the stopper wall 37 and the communication wall portion 24.

  The connecting member 31 is disposed coaxially with the container shaft O, and has a connecting shaft portion 40 disposed inside the communication opening 24a so as to penetrate the communication opening 24a, and radially outward from the connection shaft portion 40. And a plurality of connecting ribs 41 projecting radially.

  The connecting shaft portion 40 has an upper end portion that is substantially the same height as the stopper wall 37, and a lower end portion that protrudes from the communication wall portion 24 toward the inside of the container body 2. The connecting rib 41 is formed over the entire length of the connecting shaft portion 40, and is formed in a vertically long plate shape whose outer end portion in the radial direction is located in the vicinity of the opening end of the communication opening 24a. A radially outer end on the upper end side of the connecting rib 41 is connected to a radially inner end 37 a of the stopper wall 37. Thereby, the connecting member 31 can be moved up and down together with the storage cylinder 30.

  The valve body 32 has a valve body 42 having a circular shape in plan view connected to the lower end portion of the connecting shaft portion 40 and the lower end portions of the plurality of connecting ribs 41, and radially outward from the outer peripheral edge of the valve body 42. And a valve seat portion 43 extending obliquely upward and capable of opening and closing the communication opening 24a.

  As shown in FIG. 2, the valve seat portion 43 is brought into contact with the communication wall portion 24 from below, for example, in a liquid-tight manner by raising the movable inner plug 4 by removing the cap body 5 from the container body 2. It is possible to close the communication opening 24a. At this time, the movable inner plug 4 is located at the uppermost position.

  As shown in FIG. 1, when the cap body 5 is attached to the container body 2, the movable inner stopper 4 is positioned at the lowest limit position, and the valve seat portion 43 and the communication wall portion 24 are connected to each other. There is a gap between them to secure the supply port S. Therefore, the contents W in the container main body 2 can flow into the storage cylinder 30 through the communication opening 24 a while passing between the supply port S and the plurality of connection ribs 41.

The cap body 5 surrounds the upper end portion 36 a of the second guide cylinder 22 of the inner stopper member 20 and the second storage cylinder 36 of the movable inner stopper 4 from the outside in the radial direction, and the first opening in the mouth portion 3 of the container body 2. The peripheral wall portion 50 that is externally fitted to the portion 3 a and the top wall portion 51 that is connected to the upper end portion of the peripheral wall portion 50 are formed in a top tube shape.
A female screw 52 is formed at the lower end of the peripheral wall portion 50 to be screwed into the male screw 10 formed in the first mouth portion 3a. Then, by screwing (attaching) the cap body 5 to the container main body 2, the movable inner stopper 4 is connected to the coil spring 38 using the top wall portion 51 with which the upper end opening edge of the second storage cylinder 36 is in contact. The movable inner stopper 4 is positioned at the lowest limit position by pressing it against the spring force.

(Operation of the metering discharge container)
Next, the operation in the case of discharging a fixed amount of the contents W using the fixed discharge container 1 configured as described above will be described.
In this case, first, the container body 2 with the cap body 5 shown in FIG. 1 is inverted from the upright state to the inverted state as shown in FIG. Then, the contents W in the container main body 2 flow into the movable inner plug 4 through the communication opening 24a and are stored while passing between the supply port S and the plurality of connecting ribs 41.

  In addition, by setting the container main body 2 in the inverted posture, the top and bottom of the fixed-quantity discharge container 1 are inverted, and the cap body 5 along the container axis O direction is the lower side, and the bottom side of the container main body 2 is the upper side. Therefore, in the following description of the operation, the description will be made in the vertical direction in the inverted posture.

  Then, when the cap body 5 is removed while the container body 2 is in an inverted state, the movable inner stopper 4 is biased by the spring force of the coil spring 38, so that it moves downward while following the cap body 5, As a result, the valve body 32 gradually begins to block the communication opening 24a. Then, as shown in FIG. 4, when the cap body 5 is removed to such an extent that the female screw 52 of the cap body 5 and the male screw 10 of the first opening 3 a are unscrewed, the valve seat portion 43 is connected to the communication wall portion 24. Abutting from above, the communication opening 24a is completely closed and sealed.

  As a result, a certain amount of contents W can be stored inside the movable inner stopper 4, and then the cap body 5 is completely removed from the container body 2 as shown in FIG. The fixed amount of content W stored in the movable stopper 4 can be transferred into the cap body 5. Therefore, an accurate amount of the contents W can be discharged.

  In particular, since the container body 2 can be inverted once, the contents W can be discharged with a simple operation. In addition, since a certain amount of the contents W can be transferred to the cap body 5, it is difficult to zero the contents W and it is easy to reliably discharge the contents W to a desired location. Furthermore, since the valve body 32 blocks the communication opening 24a until the cap body 5 is mounted again, leakage of the contents W in the container body 2 can be prevented and it is easy to handle.

  Further, in the fixed discharge container 1, the movable inner plug 4 is urged by the coil spring 38 with the upper end opening edge of the second storage cylinder 36 in contact with the top wall 51 of the cap body 5. The state in which the upper end opening edge of the second storage cylinder 36 is in contact with the top wall portion 51 can be maintained until the body 5 is removed from the container body 2 and the valve body 32 closes the communication opening 24a. Therefore, as shown in FIG. 5, the amount of the contents W to be transferred to the cap body 5 can be easily defined by the internal volume of the movable inner plug 4, and a more accurate amount of the contents W can be discharged.

  Furthermore, in this fixed-quantity discharge container 1, since the contents W can be measured and stored at the same time using the movable inner stopper 4 and the cap body 5, the movable inner stopper 4 and the cap body 5 can be simply configured, and the partition wall It is easy to reduce costs by reducing the number of parts. Further, since the contents W are transferred to the cap body 5, it is possible to easily secure a large discharge amount for one time while keeping the cap body 5 compact.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the inner plug member 20 having the communication wall portion 24 in which the communication opening 24a is formed is fixed to the mouth portion 3 of the container body 2. However, the inner plug member 20 itself is not essential. The communication wall portion 24 in which the communication opening 24 a is formed may be integrally provided inside the mouth portion 3.

Further, regarding the screwing of the cap body 5 and the container body 2, the male screw 10 and the female screw 52 may be configured such that the cap body 5 and the container body 2 are screwed not by a single thread but by multiple threads such as a double thread.
In this way, when removing the cap body 5, the cap body 5 can be removed with a small amount of rotation (for example, half rotation). The cap body 5 can be removed. Therefore, the cap body 5 urged by the coil spring 38 can be held stably at all times, and the contents W transferred to the cap body 5 are more difficult to zero.

Moreover, although the movable stopper | plug 4 was pushed down by the cap body 5 by making the upper end opening edge of the 2nd storage cylinder 36 contact | abut to the top wall part 51 of the cap body 5, it is not limited to this case. For example, a gap may be formed between the top wall portion 51 and the upper end opening edge of the second storage cylinder 36, and a pressing leg portion that presses down the movable inner plug 4 from the top wall portion 51 may be suspended.
However, since the upper end opening edge of the second storage cylinder 36 is brought into contact with the top wall portion 51 of the cap body 5, the amount of the contents W to be transferred to the cap body 5 can be defined by the internal volume of the movable inner plug 4. More preferable.
