In addition, an operation piece 51 that protrudes outward in the radial direction is formed on the opposite side of the container axis O with respect to the hinge 50 at the upper edge of the overcap 3. When the purchaser operates the operation piece 51 and rotates the overcap 3 around the hinge 50, the overcap 3 is opened and the dispensing cylinder 2 is exposed.
In the illustrated example, the overcap 3 and the extraction member 21 are integrally formed.

According to the dispensing container 10 according to the present embodiment described above, the following operational effects can be obtained.
As shown in FIG. 3, in this pouring container 10, in order to open the pouring container 10 by connecting the pouring cylinder 2 blocked by the closing body 35, the purchaser must use the top wall of the overcap 3. When the portion 45 is moved downward, the engaging portion 47 and the pressing portion 46 are also moved downward. The engaging portion 47 can engage the engaged portion 36 of the closing body 35 and support the closing body 35. After being in the state, the pressing portion 46 abuts against the closing body 35 from above and presses down the closing body 35 to break the weakening portion 34, whereby the dispensing cylinder 2 is communicated.

  Thus, when the pouring cylinder 2 is communicated, the closing body 35 is supported by the engaging portion 47 of the overcap 3, so that even if the weakening portion 34 is broken, the closing body 35 remains in the pouring cylinder 2. It will not fall off from the bottom. Specifically, in FIG. 3, the annular concave portion 36 a of the engaged portion 36 and the annular convex portion 47 a of the engaging portion 47 are engaged with the top wall portion 45 positioned at the lowered end position. Further, since the overcap 3 supports the closing body 35 at the time of opening, the troublesome work of removing the closing body 35 from the inside of the dispensing cylinder 2 is unnecessary.

  Thus, without removing the overcap 3, it is possible to open the dispensing container 10 by making the dispensing cylinder 2 communicate with each other by a simple operation of moving the top wall portion 45 downward, and the overcap 3 can be opened. With the simple configuration in which the engaging portion 47 and the engaged portion 36 of the closing body 35 are engaged with each other, the closing body 35 can be removed from the dispensing cylinder 2 simultaneously with opening.

  Further, by confirming from the outside whether or not the top wall portion 45 of the overcap 3 has been moved downward, it can be easily recognized whether or not the dispensing container 10 is unopened. Therefore, the purchaser can easily determine whether or not the dispensing container 10 has been used.

  Further, when the top wall 45 is moved downward, the pressing portion 46 is accurately guided in the direction of the container axis O while being in contact with the guide portion 37 of the closing body 35, so that the pressing portion 46 securely moves the closing body 35. The weakened portion 34 can be surely broken.

  In addition, when the contents stored in the inner container 5 of the container main body 1 are to be poured out in the dispensing container 10, first, the overcap 3 is opened by operating the operation piece 51, and the dispensing cylinder 2 is opened. The outer container 6 of the container body 1 is squeezed (elastically deformed) in a state where the dispensing container 10 is inclined so as to face downward. Thereby, the inner container 5 is deformed together with the outer container 6 to reduce the volume. Then, the internal pressure of the inner container 5 becomes a positive pressure along with this volume reduction deformation, the elastic connecting piece 18 is elastically deformed by this positive pressure, and the pouring valve 17 is opened so that the inner container 5 and the pouring cylinder 2 communicate with each other. Is done. Thereby, the contents accommodated in the inner container 5 are poured out through the pouring cylinder 2.

Thereafter, when the internal pressure of the inner container 5 is reduced, the elastic connecting piece 18 is restored and deformed, the pouring valve 17 is closed, the communication between the inner container 5 and the pouring cylinder 2 is blocked, and the inner container 5 is sealed, Further, when the squeeze deformation described above is released, the outer container 6 tries to be restored and deformed. At this time, the negative pressure generated between the outer container 6 and the inner container 5 acts on the air valve 44, whereby the air valve 44 is activated and the intake hole 33 communicates with the outside. The outside air is sucked between the outer container 6 and the inner container 5 through the valve seat member 16 and the upper end portion 5 a of the inner container 5 and the cap body 14.
When the internal pressure between the outer container 6 and the inner container 5 rises to atmospheric pressure due to the intake of the outside air, the air valve 44 is restored and deformed to shut off the intake hole 33 and the outside. As described above, when the outside air is sucked between the outer container 6 and the inner container 5, the volume reduction shape of the inner container 5 is maintained.

  From this state, when the outer container 6 of the container body 1 is squeezed again, the air valve 44 is shut off, so that the internal pressure between the outer container 6 and the inner container 5 becomes a positive pressure. Thus, the inner container 5 is deformed and reduced in volume. By reducing the volume of the inner container 5, the same action as described above is obtained, and the contents are poured out.

  According to the pouring container 10, the pouring valve 17 is opened when the contents are poured out, and the pouring valve 17 is closed after the pouring. The sealing property of the container main body 1 to be accommodated is improved. Therefore, the operation of pouring the contents becomes simple and the quality of the contents is stably maintained.

  In addition, since the container body 1 is a double container including the inner container 5 and the outer container 6, even if the squeezed outer container 6 is restored and deformed, the inner container 5 is reduced in content. The volume is reduced, and the outside air is prevented from flowing into the inner container 5. Thereby, deterioration of the content is prevented and the preservability is improved.

  The inner container 5 is detachably mounted on the outer container 6, and the upper end portion 5 a of the inner container 5 is fixed to the dispensing cap 4. Therefore, after all the contents are poured out, the inner container 5 is also removed from the outer container 6 together with the dispensing cap 4 by removing the dispensing cap 4 from the outer container 6 as shown in FIG. ing. Specifically, when removing the dispensing cap 4 from the outer container 6, when the mounting cylinder 23 is rotated in the circumferential loosening direction with respect to the mouth 1 a of the container body 1, the mounting cylinder 23 is moved relative to the mouth 1 a Move upwards. On the other hand, in the restriction cylinder 25, the restriction claw portion 25a comes into contact with the flange portion 9 from below and the upward movement is restricted, so that the bridge 24 is broken. Thereby, the extraction cap 4 can be removed from the outer container 6.

  In this way, the simple operation of rotating the mounting cylinder 23 in the loosening direction allows the dispensing cap 4 and the inner container 5 to which the contents are attached to be easily separated from the outer container 6, so that depending on the type of the contents Therefore, the outer container 6 can be easily recycled.

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

For example, in the above-described embodiment, the overcap 3 is integrally formed with the pouring member 21 of the cap body 14 via the hinge 50, but is not limited thereto.
The dispensing container 60 shown in FIGS. 5 to 8 is a modified example of the dispensing container 10 described above. The dispensing container 60 is not provided with a hinge 50, and the overcap 3 has an undercut fit. As a result, the cap body 14 is detachably mounted. Further, in the dispensing container 60, the above-described dispensing member 21 and the mounting member 20 are integrally formed to form the cap body 14. Even in such a configuration, the same effect as described above can be obtained.

  In the above-described embodiment, the overcap 3 is provided with the pressing portion 46 that protrudes downward from the top wall portion 45.
