The operation of the discharge container 1 of this embodiment will be described below.
When discharging the contents from the discharge container 1, first, the cap 8 is removed from the mouth portion 3 of the container body 2 to expose the discharge hole 12, and then the discharge container 1 is positioned with the mouth portion 3 downward. , and the bottom portion (not shown) of the container main body 2 is positioned upward, in an inverted or inclined position. In this state, when the outside air introduction hole is closed with a finger and the outer container 6 of the container body 2 is squeeze-deformed, the inner container 4 is deformed together with the outer container 6 to reduce the volume. As a result of this volume-reducing deformation, the internal pressure of the inner container 4 becomes a positive pressure, and this positive pressure elastically deforms the peripheral portion 35 of the valve portion 31 to open the communication hole 21, so that the discharge hole 12 and the interior of the inner container 4 are separated. communicated.

When the valve portion 31 is opened in this manner, the contents in the inner container 4 pass between the inner peripheral surface of the inner plug 20 and the outer peripheral surfaces of the holding cylinder member 40 and the leg portion 32, and then It passes through the communication hole 21 . After passing through the communication hole 21 , the contents flow into the space between the upper surface of the valve portion 31 and the lower surface of the ceiling wall portion 11 of the discharge nozzle 10 and are discharged from the discharge hole 12 . At this time, the contents discharged from the discharge hole 12 and reaching the upper surface of the ceiling wall portion 11 are collected by the liquid collecting top portion 25a along the liquid collecting portion 25, and fall as droplets.

After the contents are discharged, when the internal pressure of the inner container 4 decreases, the peripheral edge portion 35 of the valve portion 31 is seated on the upper surface of the valve seat 24, and the communication between the discharge hole 12 and the inside of the inner container 4 is cut off. By closing the valve portion 31 in this way, the inner container 4 is sealed, and when the blockage of the external air introduction hole and the squeeze deformation by fingers are released, the outer container 6 attempts to restore and deform. At this time, since the inner container 4 is sealed, a negative pressure is generated between the outer container 6 and the inner container 4 . Then, outside air is introduced between the outer container 6 and the inner container 4 through the above-described outside air introduction hole of the outer container 6 . In this way, by introducing outside air between the outer container 6 and the inner container 4, the volume-reduced shape of the inner container 4 is maintained.
Thus, the operation of discharging the contents using the discharge container 1 is completed.

As described in detail above, in the discharge container 1 of the present embodiment, the contents fall as droplets from the liquid collecting top portion 25a. As compared with the configuration in which a recessed portion is formed in the opening peripheral portion of the container, the content remaining on the top wall portion 11 after dripping can be reduced.

In addition, since the part 25b of the liquid collecting part 25 is located at the peripheral edge of the opening of the discharge hole 12 in the top wall part 11, the contents reaching the top surface of the top wall part 11 through the discharge hole 12 are immediately discharged. reaches the portion 25b of the liquid collecting portion 25 at a later time. Since the liquid collecting portion 25 gradually extends upward from the portion 25b toward the liquid collecting top portion 25a, the contents reaching the portion 25b of the liquid collecting portion 25 are smoothly collected. It is led to the liquid top portion 25a.
As described above, it is possible to suppress the contents discharged from the discharge hole 12 from diffusing and adhering to the top wall portion 11, thereby reliably reducing the contents remaining on the top wall portion 11. be able to.

In addition, the liquid collecting portion 25 is formed over the entire portion of the top wall portion 11 located on one side of the first reference line L1, and gradually increases upward as it separates from the first reference line L1 in the orthogonal direction. Since the upper end portion of the liquid collecting top portion 25a has a width in the direction in which the first reference line L1 extends, it is possible to prevent this portion from sharply sharpening, so that the user can easily It is possible to prevent anxiety when using the discharge container 1 .
In addition, since the ejection hole 12 is formed in the central portion of the top wall portion 11 and the liquid collection top portion 25a is arranged on the second reference line L2, the liquid is ejected from the ejection hole 12 and the part of the liquid collection portion 25 is discharged. The contents reaching 25b do not diffuse on the ceiling wall 11 and can easily move straight toward the collecting top part 25a, allowing the contents to drip smoothly and remain on the ceiling wall 11 Contents can be reduced more reliably.
