The mouth cylindrical body 9 is formed in a cylindrical shape having a circular cross section that decreases in diameter upward. The cylindrical wall 7, the bottom wall 8, and the mouth cylindrical body 9 are integrally formed of a resin material.

  In the present embodiment, the inner plug 6 is fixedly held on the mouth portion 4 of the container body 2 by press-fitting the large-diameter portion 7 a of the cylindrical wall 7 into the inside of the mouth portion 4. The inner plug 6 is not limited to the fixing structure by press-fitting. For example, the inner wall 6 is attached to the mouth part 4 by another fixing structure, such as screwing the cylindrical wall 7 to the mouth part 4 or engaging the mouth part 4 with an undercut. It can also be set as the structure made. The container body 2 is configured to discharge the contents from the front end opening 9 a of the mouth tube 9 having a smaller diameter than the opening of the mouth portion 4 by mounting the inner plug 6 on the mouth portion 4.

  A cap 11 that covers the mouth 4 and the inner plug 6 is detachably attached to the mouth 4 of the container body 2. The cap 11 includes a substantially cylindrical side wall 12 and a top wall 13 that covers the top of the side wall 12. The side wall 12 is formed of a resin material, and a lower part thereof has a double structure composed of an inner cylinder part 12a and an outer cylinder part 12b. A female screw 12 c is provided on the inner peripheral surface of the inner cylinder portion 12 a, and this female screw 12 c engages with a male screw 4 a provided on the outer peripheral surface of the mouth portion 4. Thereby, the side wall 12 can be moved up and down with respect to the mouth portion 4, and the cap 11 can be moved with respect to the container body 2 to move from the lower position shown in FIG. 1 to the upper position shown in FIG. it can. The cap 11 can be removed from the container body 2 by further rotating in the screwing direction from the position shown in FIG. That is, the cap 11 is detachably attached to the container body 2.

  The upper part of the side wall 12 has an inner diameter dimension equivalent to the outer diameter dimension of the upper part of the mouth part 4. A discharge hole 14 is formed in the upper part of the side wall 12. As shown in FIG. 1, when the cap 11 is in the lower position, the upper surface of the cylindrical wall 7 (the upper surface of the flange 7 b) comes into contact with the inner surface (lower surface) of the top wall 13 and the discharge hole 14 is closed. 2, when the cap 11 is in the upper position, the upper surface of the cylindrical wall 7 (the upper surface of the flange 7b) and the inner surface of the top wall 13 are separated from each other, and the discharge hole 14 is opened.

  The cap 11 has a partition wall 15 that hangs down from the inner surface of the top wall 13 and is disposed inside the cylindrical wall 7 and outside the mouth cylindrical body 9. As shown in FIG. 2, the lower end of the partition wall 15 is positioned below the upper end of the mouth tube body 9 with the cap 11 in the upper position. As a result, the measuring chamber 16 is formed above the mouth cylinder 9. The top wall 13 is provided with a seal cylinder 17 positioned outside the partition wall 15, and the seal cylinder 17 abuts against the inner surface of the large-diameter portion 7 a of the cylinder wall 7 in the state shown in FIG. This enhances the effect of preventing things from leaking outside.

  In the present embodiment, as shown in FIG. 1, when the cap 11 is in the lower position, the lower end surface of the partition wall 15 is in contact with the upper surface of the horizontal portion 8 a. To prevent the contents from moving.

  Next, a method for using the quantitative discharge container 1 having such a configuration, that is, a procedure for quantitatively discharging the contents will be described. As shown in FIG. 1, in a state where the cap 11 is completely screwed to the container body 2, the discharge hole 14 is closed as described above. Therefore, the contents do not leak to the outside during storage or transportation.

  When discharging a fixed amount of contents from the fixed discharge container 1, first, the cap 11 is rotated in the screwing direction, and the cap 11 is moved to the upper position with respect to the container body 2 as shown in FIG. Move. As a result, the measurement chamber 16 communicates with the discharge hole 14 via the storage chamber 10. Next, as shown in FIG. 3A, when the fixed amount discharge container 1 is in an inverted posture in which the cap 11 is on the lower side with respect to the container body 2, the contents in the storage space 3 a are placed in the measuring chamber 16. Inflow. At this time, when the upper surface of the contents accumulated in the measuring chamber 16 becomes the same height as the tip opening 9a of the mouth tube 9, the inflow of the contents into the measuring chamber 16 is stopped. Thereby, the amount of contents flowing into the measuring chamber 16 is always constant.

  Next, when the quantitative discharge container 1 is returned to the upright posture, the contents move from the measuring chamber 16 to the storage chamber 10, and a predetermined amount of the contents are stored in the storage chamber 10 as shown in FIG. Stored. Then, as shown in FIG. 3C, when the quantitative discharge container 1 is tilted so that the discharge hole 14 is downward, the contents stored in the storage chamber 10 are discharged through the discharge hole 14. Since the contents in the storage chamber 10 are measured in the measuring chamber 16, an accurate amount of the contents is discharged from the discharge hole 14. At the same time as the contents are discharged from the discharge hole 14, the contents in the storage space 3a flow into the measuring chamber 16 and are metered. A quantity of contents can be discharged repeatedly.

  In the fixed-quantity discharge container 1 of the present embodiment, the discharge hole 14 is provided in the side wall 12 of the cap 11, thereby providing a discharge hole in the top wall of the cap 11 and opening and closing the discharge hole above it. The height of the cap 11 can be kept low as compared with the case of providing the cap. Thereby, the height as the whole fixed quantity discharge container 1 can be made low, and size reduction of the fixed quantity discharge container 1 is realizable.

  Moreover, in the fixed-quantity discharge container 1 of this embodiment, by having the structure which opens and closes the discharge hole 14 only by operation which rotates the cap 11 with respect to the container main body 2, and moves the cap 11 to an up-down direction, It is not necessary to provide a lid for opening and closing the discharge hole via the hinge portion, and the configuration is simplified.

  Hereinafter, another embodiment of the present invention will be described. In addition, about the structure which is the same as that of previous embodiment, or corresponding, it represents with the same code | symbol, and abbreviate | omits description again.

  In this embodiment, as shown to Fig.4 (a), it is set as the structure shape | molded in the state which the inside plug 6 and the cap 11 were integrally connected via the weakening part 21, For example, the metal mold | die opened up and down is used. Molding is possible by injection molding.

  Moreover, in this embodiment, the side wall 12 and the top wall 13 of the cap 11 are connected via the hinge part 22 so that rotation is possible. An inner wall 23 protruding inward from the inner peripheral surface is provided on the upper portion of the side wall 12, and the weakened portion 21 connects the inner surface of the inner wall 23 and the flange 7 b of the cylindrical wall 7. In the present embodiment, the discharge hole 14 is formed by providing a notch in the side wall 12 and the inner wall 23 on the side facing the hinge portion 22. The top wall 13 is provided with a seal wall 24 that comes into contact with the upper inner surface of the inner wall 23, thereby enhancing the sealing performance between the top wall 13 and the side wall 12. In addition, it is preferable that the weakened portion 21 is configured to be easily broken by providing an intermittent portion in the circumferential direction or by making it thin.

  The cap 11 of the present embodiment is formed with the top wall 13 open as shown in FIG. 4A, and then assembled to the container body 2 as shown in FIG. 4B. Is closed and assembled to the container body 2 containing the contents. When the cap 11 is first assembled to the container body 2, when the side wall 12 of the cap 11 is screwed onto the mouth portion 4 of the container body 2, the flange 7 b is supported on the upper end of the mouth portion 4 and the inner plug 6 is attached. When the downward movement is stopped and the inner wall 23 of the side wall 12 is moved downward, the weakened portion 21 is pulled and broken. When the weakened portion 21 is broken, the inner plug 6 and the cap 11 are separated, and the inner plug 6 is held in the mouth portion 4 as shown in FIG.

  In the present embodiment, the contents can be quantitatively discharged in the same procedure as in the previous embodiment. That is, after rotating the cap 11 of the metering discharge container 20 shown in FIG. 5 in the screwing direction to open the discharge hole 14, and once letting a predetermined amount of contents flow into the measuring chamber 16 from the storage space 3 a as an inverted posture, The predetermined amount of contents is stored in the storage chamber 10 by returning to the upright posture. Then, by inclining the metering discharge container 20 in an inverted posture so that the discharge hole 14 is positioned downward, the contents can be metered and discharged, and at the same time, the contents can be re-weighed in the measuring chamber 16.

  In the fixed discharge container 20 of the present embodiment, the number of parts can be reduced by integrally molding the inner plug 6 and the cap 11. As a result, the number of molds and the part setting process are reduced, so that the manufacturing cost can be kept low. In the present embodiment, similarly to the previous embodiment, it is possible to obtain the effect of realizing the downsizing of the metering discharge container 20 by keeping the height of the cap 11 low.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the claims. For example, in the previous embodiment, Although the mouth 4 of the container body 2 and the cap 11 are engaged with each other by screws, the present invention is not limited to this. For example, an undercut engagement may be adopted. In this case, the cap 11 can be moved between the upper position and the lower position by pulling up or down straight along the central axis C without rotating the cap 11 with respect to the container body 2.
