The groove portion 74 is L-shaped in a cross-sectional view as viewed from the radial direction, and a plurality of the groove portions 74 are formed at intervals in the circumferential direction. A gap defined between the groove portion 74 and the mounting portion 37 and the closing portion 36 communicates the inside of the lower dispensing cylinder 34 and the inside of the container main body 11 with negative pressure in the container main body 11. A suction passage S that sucks outside air toward the inside of the container main body 11 when it occurs is formed. In the present embodiment, the depth and width of the groove 74 are preferably set to 0.5 (mm) or less.

Next, the operation of the above-described dispensing container 1 will be described. In the following description, the initial state is a state in which the dispensing container 1 is in the upright posture and both the second lower cap 27 and the second upper cap 52 are in the closed position.
First, the weighing mode will be described.
First, in a state where the container body 11 in the initial state is gripped, the second lower cap 27 is set to the open position, and the lower dispensing cylinder 34 (the lower dispensing outlet 34a) is opened. Specifically, by placing a finger or the like on the lower operation piece 43 and pulling up the lower operation piece 43, the second lower cap 27 rotates around the hinge portion 26 together with the upper cap 22. As a result, the lower pouring outlet 34a is opened.

  Then, as shown in FIG. 3, the dispensing container 1 is tilted to a dispensing posture in which the dispensing cap 12 (the lower dispensing outlet 34 a) faces downward and the bottom of the container body 11 faces upward. Then, although the contents in the container main body 11 flow into the lower dispensing cylinder 34 through the communication hole 35, the flow to the downstream side (the lower dispensing outlet 34 a side) is blocked by the operating portion 73. At this time, the weight of the contents acts on the operating portion 73.

  In this state, a finger is positioned in the finger holding recess 14 of the container main body 11, and the container main body 11 is elastically deformed radially inward via the finger holding recess 14 (see the arrow in FIG. 3). When the container body 11 is elastically deformed and the volume of the container body 11 is reduced, the pressure in the container body 11 becomes positive. Then, the operating portion 73 of the valve member 71 is elastically deformed toward the inner side in the radial direction and separated from the inner peripheral surface of the lower dispensing cylinder 34. As a result, the valve member 71 is opened and the communication hole 35 is opened, so that the inside and outside of the container body 11 communicate with each other through the lower dispensing cylinder 34. As a result, the contents in the container main body 11 are poured out from the lower pouring outlet 34a.

  Specifically, the content that has flowed into the lower dispensing cylinder 34 flows through the lower dispensing cylinder 34 through the gap between the operating portion 73 and the lower dispensing cylinder 34, and then from the lower dispensing outlet 34a. Be poured out. When the pressure in the container body 11 returns to the atmospheric pressure, the operating portion 73 of the valve member 71 is restored and deformed and is seated on the inner peripheral surface of the lower dispensing cylinder 34. As a result, the valve member 71 is closed and the communication hole 35 is closed, so that the communication inside and outside the container body 11 through the lower dispensing cylinder 34 is blocked.

  Here, in the measurement mode, elastic deformation of the container main body 11 in the radial direction is restricted by elastically deforming the container main body 11 to a position where the concave portion 14 for finger contact comes into contact with the restriction portion 23. Thereby, the volume reduction of the container main body 11 at the time of pouring becomes always constant, and a desired amount of contents can be poured out each time. In addition, at the time of the above-mentioned extraction, the contents in the container main body 11 may flow through the suction passage S toward the lower injection outlet 34a.

Next, the small amount mode will be described.
In the small amount mode, the second upper cap 52 is set to the open position, and the upper pouring cylinder 55 (upper pouring outlet 55a) is opened. Specifically, by placing a finger or the like on the upper operation piece 64 and pulling up the upper operation piece 64, the second upper cap 52 rotates around the hinge portion 63. Thereby, the upper pouring outlet 55a is opened.

  Then, as shown in FIG. 4, the container body 11 is elastically deformed radially inward through the fingernipping recesses 14 in a state in which the dispensing container 1 is in the pouring posture (the arrow in FIG. 4). reference). At this time, the container main body 11 is elastically deformed to such an extent that the finger holding recess 14 does not contact the restricting portion 23.

  Thereby, the valve member 71 is opened similarly to the measurement mode described above. Then, the inside and outside of the container body 11 communicate with each other through the lower dispensing cylinder 34 and the upper dispensing cylinder 55 by opening the communication hole 35. As a result, a small amount of the contents in the container body 11 is poured out from the upper pouring outlet 55a. Specifically, the contents in the container main body 11 flow into the lower dispensing cylinder 34 through the communication hole 35, and then pass through the gap between the operating portion 73 and the lower dispensing cylinder 34. Circulate inside. Thereafter, the contents flow into the upper dispensing cylinder 55 through the lower plug cylinder 56, and are then dispensed from the upper dispensing outlet 55a.

  Here, as shown in FIG. 5, after the contents are poured out, when the container 1 is returned to the initial state and the container body 11 is restored and deformed, negative pressure is generated in the container body 11. Then, the contents remaining in the intermediate portion located between the lower pouring outlet 34a and the valve member 71 in the lower pouring cylinder 34 (for example, the contents remaining on the valve member 71, the mounting portion 37, etc.). The object) is pulled back into the container body 11 together with the outside air through the suction passage S. That is, the content remaining in the intermediate portion described above flows through the suction passage S toward the container body 11 and then flows into the container body 11 through the communication hole 35 (see the arrow in FIG. 5). . Thereby, it can suppress that a content remains in the intermediate part mentioned above after pouring out of a content.

Thus, in this embodiment, by forming the suction passage S between the mounting portion 37 and the valve member 71, it is possible to suppress the contents from remaining in the intermediate portion described above due to the suck back effect described above. For example, the occurrence of dripping can be suppressed.
In addition, in the present embodiment, the suction passage S is formed between the base portion 72 and the mounting portion 37 of the valve member 71 that are less likely to change with time than the operating portion 73, thereby reducing the negative in the container body 11. The outside air can be stably sucked when pressure is generated.

  Moreover, in this embodiment, the depth and width | variety of the groove part 74 are set to 0.5 (mm) or less, for example, the content whose viscosity is 10 (mPa * s) or more is accommodated in the container main body 11. FIG. In this case, it is possible to suppress unintentional outflow of contents through the suction passage S when the dispensing container 1 falls or falls. In the present embodiment, as the content having a viscosity of 10 (mPa · s) or more, for example, liquid cosmetics such as lotion, liquid seasonings such as mirin, edible oil, and liquid soap are preferably used. it can.
