The clogging clearing member 30 is a loosening portion formed by arranging a plurality of strips 33 radially extending on the upper end side of the rod-shaped lot portion 31 and slits 34 between adjacent strips 33, respectively. 32 is provided. That is, the loosening portion 32 has a configuration in which a plurality of strips 33 are arranged in a row in the circumferential direction with slits 34 in between, and the slits 34 have sufficient margin for the contents P solidified in a mass to pass through. It is formed with a width dimension with.

As shown in FIG. 1, in the initial state before deformation, the clogging clearing member 30 has a lot portion 31 inserted in the container body 10. When the lower end portion 35 of the lot of the clogging clearing member 30 is fitted and held by the reverse recessed portion 18, the loosening portion 32 is pressed by the inner peripheral surface of the mouth cylinder portion 11 on the upper end side, so that the lower end side of the loosening portion 32 is curved. It is set to a basket shape that deforms and swells round. In this initial state, the loosening portion 32 is set so that the upper end of the band 33 is slightly lower than the upper end of the mouth cylinder portion 11. Further, the lot lower end portion 35 is fitted and held in the reverse recessed portion 18 so as to be hard to come off, so that the bottom portion 14 and the lot lower end portion 35 are interlocked with each other.

Next, the use of the discharge container 1 having the above configuration will be described.
In the discharge container 1, after filling the container body 10 with the powdery or granular content P, the clogging clearing member 30 is inserted to embed the lot lower end portion 35 in the content P, and the reverse depression portion is formed. The cap 20 is fitted and held at 18, and then the cap 20 is screwed around the mouth tube portion 11. It is preferable to attach a sheet-shaped sealing material (not shown) to the upper end of the discharge port 24 in that the inside of the container body 10 can be set in a sealed state.

When the discharge container 1 is used, the lid 25 of the cap 20 is rotated to open the lid, and a sealing material (not shown) is peeled off to open the discharge port 24. Then, as shown in FIG. 2, when the user sets the discharge port 24 side of the discharge container 1 in an inverted inclined posture facing downward, the content P passes through the slit 34 and moves into the loosening portion 32. The content P can be discharged through the discharge port 24 provided at the tip of the loosening portion 32.

Next, the discharge of the content P, which is in a state of being solidified in a lump due to the influence of humidity, its own weight, etc., will be described.
As shown by the solid line in FIG. 2, the user pushes the bottom portion 14 inward and moves the clogging clearing member 30 toward the mouth cylinder portion 11 (pushing operation). Then, in conjunction with this pushing operation, the upper ends of the plurality of strips 33, which are the tips of the loosening portions 32, come into contact with the inner surface of the tapered portion 23 of the cap body 21, and on the inner surface of the tapered portion 23 having a gradient. It slides in the direction of the inner diameter approaching the container shaft O and the direction of the discharge port 24. As a result, the loosening portion 32 can be deformed in the direction in which the radial dimension of the tip (upper end of the plurality of strips 33) contracts (contraction deformation due to the closing operation).

Next, as shown by the broken line in FIG. 2, the pushing of the bottom portion 14 by the user is released (release operation). Then, in conjunction with this release operation, the upper ends of the plurality of strips 33, which are the tips of the loosening portions 32, move on the inner surface of the tapered portion 23 in the opposite direction to the previous direction, that is, in the outer diameter direction away from the container axis O direction. It slides toward the bottom 14. As a result, the tip of the loosening portion 32 (the upper end of the plurality of strips 33) can be deformed in the direction of expansion to return to the original diameter dimension before the deformation (expansion deformation due to the opening operation), and the clogging clearing member 30. Moves in the direction of returning to the bottom 14, so that the bottom 14 can be restored to the original initial state of bulging outward.

In this way, when the user repeatedly pushes and releases the bottom portion 14, the lot portion 31 constituting the clogging clearing member 30 reciprocates along the container shaft O, and the unraveling portion 32 contracts and expands and deforms. Since the opening / closing operation is performed by repeating the above steps, the lumpy content P that has entered the loosening portion 32 can be finely crushed. Then, the crushed content P can be smoothly discharged through the discharge port 24 provided at the tip of the loosening portion 32 in the same manner as described above.

When the content P is a larger lump-like mass, the large lump-like content P is shaken greatly by shaking the discharge container 1 itself to transfer the large lump content P to the body portion 13, the bottom portion 14, and the lot portion 31 of the container body 10. Alternatively, the slit 34 can be passed by colliding with the loosening portion 32 and crushing the mixture.

Although the configuration of the present invention and its action and effect have been described above with reference to Examples, the embodiments of the present invention are not limited to the above Examples.
For example, in the above embodiment, the unraveling portion 32 that opens and closes in conjunction with the deformation operation of the bottom portion 14 is provided at the position on the mouth cylinder portion 11 side of the container body 10, but the unraveling portion 32 is described, for example. It may be configured to be provided at an intermediate height position of the body portion 13 or a position on the bottom portion 14 side.

The discharge container of the present invention can be used in a wider range of applications in the field of a container for accommodating contents that tend to be lumpy.
