  An opening member 18 for opening the slit valve 12 is attached to the inner surface of the top wall 16. The opening member 18 includes a cylindrical portion 19 formed in a cylindrical shape that is coaxial with the outlet 4 and the discharge hole 10 of the inner plug 6. The outer dimension of the cylindrical portion 19 is slightly smaller than the inner diameter dimension of the discharge hole 10 and the cut length of the slit valve 12, and faces the slit valve 12 at one end in the axial direction.

  A cylindrical fixed shaft 21 is coaxially and integrally provided on the cylindrical portion 19 via a connecting piece 20. The fixed shaft 21 is fixed to a fixed cylinder 22 provided at the center of the inner surface of the top wall 16 by press-fitting or undercut engagement, whereby the opening member 18 is fixed to the inner surface of the top wall 16.

  The opening member 18 is not limited to the configuration fixed to the inner surface of the ceiling wall 16, and may be configured to be formed integrally with the ceiling wall 16 on the inner surface of the ceiling wall 16.

  The connecting piece 20 that connects the cylindrical portion 19 of the opening member 18 and the fixed shaft 21 is inclined so as to gradually narrow the interval from the cylindrical portion 19 toward the fixed shaft 21, and the interval in the circumferential direction is increased. They are arranged side by side. Thereby, a plurality of communication holes 23 are partitioned and formed in the circumferential direction by the connecting piece 20 between the cylindrical portion 19 of the opening member 18 and the fixed shaft 21. These communication holes 23 communicate the inside of the cylindrical portion 19 with the measurement space 17. As described above, in the present embodiment, the opening member 18 is configured as a hopper type that includes the cylindrical portion 19 and the communication hole 23 defined in the inclined connecting piece 20.

  Next, based on FIGS. 2-5, the usage method of the fixed discharge container 1 of such a structure, ie, the procedure which discharges the content quantitatively, is demonstrated.

  As shown in FIG. 1, in the normal state (natural state), the top wall 16 of the cap 13 has an initial shape protruding upward with respect to the side wall 14, and the opening member 18 is in contact with the slit valve 12. The discharge hole 10 is closed by the slit valve 12. 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, as shown in FIG. 2, the fixed discharge container 1 in which the content is stored in the storage space 3 a of the storage unit 3 is placed in the container body 2. In contrast, the inverted posture is such that the cap 13 is on the lower side. In this state, the top wall 16 is pushed toward the slit valve 12 and elastically deformed toward the slit valve 12. When the top wall 16 is elastically deformed into a pushing shape that is pushed toward the slit valve 12, the cylindrical portion 19 of the opening member 18 comes into contact with the slit valve 12, and further the slit valve 12 is elastically deformed to open the cut. , Is inserted into the discharge hole 10. Thereby, the slit valve 12 is opened by the opening member 18, and the accommodation space 3 a is communicated with the measurement space 17 through the cylindrical portion 19 and the communication hole 23.

  Therefore, when the slit valve 12 is opened, the contents accommodated in the accommodation space 3 a pass through the inside of the cylindrical portion 19 of the opening member 18 inserted into the discharge hole 10 and the communication hole 23 into the measurement space 17. The metering space 17 is filled with a certain amount of contents. At this time, since the opening member 18 is formed in a hopper type, even if the measuring space 17 is radially expanded with respect to the discharge hole 10, the accommodating space 3 a is changed to the measuring space 17 through the discharge hole 10. A certain amount of contents can be introduced with high accuracy. In addition, since the upper wall 9 of the inner plug 6 is formed in an inclined shape from the inside to the outside, even if the content flowing into the measuring space 17 becomes a mountain shape, the upper wall 9 follows the mountain shape. Thus, the contents can be stably measured.

  As shown in FIG. 3, when the pushing of the ceiling wall 16 toward the slit valve 12 is released, the ceiling wall 16 automatically restores to its initial shape. As a result, the opening member 18 comes out of the slit valve 12, the slit valve 12 returns to the closed state, and the discharge hole 10 is closed. When the discharge hole 10 is closed by the slit valve 12, the outflow of contents from the accommodation space 3 a to the measurement space 17 is stopped.

  Next, as shown in FIG. 4, the quantitative discharge container 1 is returned to the upright posture with the cap 13 on the upper side with respect to the container body 2, and the cap 13 is removed from the mouth portion 4. When the cap 13 is removed from the mouth portion 4, the contents are accommodated in the space defined by the upper wall 9, the peripheral wall 15, and the slit valve 12 of the inner plug 6.

  Then, as shown in FIG. 5, by tilting the container main body 2 at an arbitrary angle, a certain amount of contents stored in the space defined by the upper wall 9, the peripheral wall 15, and the slit valve 12 of the inner plug 6 are removed. , And can be discharged toward a desired discharge target such as a container. At this time, since the discharge hole 10 of the inner plug 6 is closed by the slit valve 12, even if the container body 2 is tilted, the content does not leak out from the housing space 3a.

  Thus, in the fixed-quantity discharge container 1 of the present invention, the content discharged from the discharge hole 10 is measured in a constant amount in the measurement space 17 between the slit valve 12 and the cap 13 and the content measured in the measurement space 17. The object can be discharged to the outside as it is with the cap 13 removed. Therefore, in this invention, the cap 13 should just be formed in the magnitude | size in which only one measurement space 17 is provided, and compared with the case where a measurement chamber and a storage chamber are provided, cap 13 can be reduced in size. it can.

  In addition, after the weighing space 17 is filled with the contents, the weighing space 17 is blocked from the accommodation space 3a of the container body 2 by the slit valve 12, so that the accommodation space 3a of the container body 2 is discharged when the contents are discharged. It is possible to prevent the contents from leaking out. Therefore, the contents can be discharged from the fixed discharge container 1 accurately by a certain amount.

  FIG. 6 is a cross-sectional view showing a modification of the metering discharge container 1 shown in FIG. In FIG. 6, members corresponding to those described above are denoted by the same reference numerals, and description thereof is omitted.

  In the quantitative discharge container 1 shown in FIG. 6, a guide wall 24 is provided on the upper wall 9 of the inner stopper 6 on the upper surface of the holding portion 9b. The guide wall 24 is formed in a cylindrical shape that extends along the periphery of the discharge hole 10 and protrudes toward the upper side opposite to the accommodation space 3a. The inner diameter of the guide wall 24 is the same as the inner diameter of the discharge hole 10. ing. The guide wall 24 is opposed to the outer side in the radial direction of the cylindrical portion 19 of the opening member 18 with a predetermined interval, with the top wall 16 having an initial shape.

  Thereby, for example, even if the top member 16 formed of a rubber material is pushed obliquely with respect to the axial direction and the opening member 18 is pushed in a direction inclined in the axial direction, the opening member 18 The cylindrical portion 19 is guided toward the discharge hole 10 by the guide wall 24, and the slit valve 12 can be reliably opened by the opening member 18.

  Note that the guide wall 24 is not limited to a cylindrical shape, and may be disposed on the outer side in the radial direction of the opening member 18 so as to guide the opening member 18. Other shapes such as a plurality of wall pieces and protrusions arranged side by side are also possible.

  In the fixed discharge container 1 shown in FIG. 6, the protruding height from the mouth portion 4 in a predetermined range in the circumferential direction of the peripheral wall 15 of the inner plug 6 is formed to be higher than the protruding height in the other part of the peripheral wall 15. ing. In the case shown in FIG. 6, the protrusion height of the right side portion of the peripheral wall 15 in the drawing is higher than the left portion in the drawing so as to be the same height as the top wall 16 of the initial shape. . Although not shown in detail, the height of the peripheral wall 15 smoothly and gradually changes between them. Further, the small-diameter portion 14 a of the side wall 14 of the cap 13 is extended upward in accordance with the height of the peripheral wall 15 to form a groove portion 14 e that can accommodate the peripheral wall 15.

  As described above, when the protruding height of a part of the peripheral direction of the peripheral wall 15 is made higher than that of the other part, the peripheral wall is removed when the cap 13 is removed from the mouth portion 4 and the measured contents are discharged to the outside. By using the portion having a high protrusion height of 15 as a spout, the contents can be stably guided by the peripheral wall 15 so that the contents are less likely to scatter around during discharge.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above embodiment, the inner plug 6 is attached to the mouth portion 4 of the container main body 2 and the slit valve 12 is provided in the discharge hole 10 of the inner plug 6. The inner plug 6 may not be attached to the mouth portion 4 of the main body 2, and the slit valve 12 may be provided directly on the mouth portion 4.

  The slit valve 12 is not limited to the cross shape, and can be arbitrarily provided as long as the main body 12a can be elastically deformed and opened, for example, in a radial manner.

  Furthermore, the opening member 18 is not limited to the hopper type having the cylindrical portion 19, and any shape, size, etc. can be used as long as it can contact the slit valve 12 and open it by elastic deformation. It can be set arbitrarily.

  Furthermore, the top wall 16 of the cap 13 is not limited to a structure that automatically restores to an initial shape by an elastic body such as rubber, but is formed of a soft material and can be deformed but not restored to an initial shape. It can also be. In this case, a projection or the like for returning the deformed ceiling wall 16 to the initial shape can be provided on the outer peripheral surface of the ceiling wall 16.

  Further, the peripheral wall 15 is not limited to a cylindrical shape, and may be a shape in which an intermittent portion is provided in a part of the circumferential direction. In this case, the contents can be discharged from the intermittent portion.
