First, the case where the contents are discharged from the first discharge hole 14 will be described.
In this case, when the pressing head 41 is pressed after the lid portion 16 is removed, the stem 38 is moved downward against the urging force of the urging member 49. At this time, the piston 48 moves downward while being in sliding contact with the inner peripheral surface of the cylinder 47, and the contents in the cylinder 47 are compressed. Then, after the contents are introduced into the stem 38 and flow upward in the stem 38 and the joint member 40, the contents flow into the pressing head 41, and then the concave groove formed in the core portion 57 is inserted into the depression 57. It passes through the first discharge hole 14 and is discharged (sprayed). When the pressing of the pressing head 41 is released, the piston 48, the stem 38, and the pressing head 41 are restored and displaced based on the elastic restoring force of the urging member 49. At this time, the contents in the container main body 11 are sucked into the cylinder 47 through the suction pipe 42 and the outside air is sucked into the container main body 11 through the intake hole 50.

Next, the case where the contents are discharged from the second discharge hole 32 will be described.
In this case, after the lid portion 16 is removed, for example, the container body 11 is squeezed while being tilted, so that the pressure from the inside of the container body 11 is applied to the discharge valve 35 through the communication hole 31, and the discharge valve 35 is Operate. Then, as shown in FIG. 3, the second discharge hole 32 is opened, and the contents in the container body 11 are discharged through the second discharge hole 32. When the squeeze deformation of the container body 11 is stopped or released, the pressure acting on the discharge valve 35 from within the container body 11 is weakened, the discharge valve 35 is restored and deformed, and the second discharge hole 32 is closed.
When the squeeze deformation of the container body 11 is released and the container body 11 is restored and deformed, the negative pressure generated in the container body 11 acts on the air valve 36 and the air valve 36 is activated. Then, as shown in FIG. 4, the air hole 33 is opened and the outside air is introduced into the container body 11 through the communication path 34 and the communication hole 31. When the pressure in the container main body 11 returns to the same level as the atmospheric pressure, the air valve 36 is restored and deformed, and the air hole 33 is closed.

As described above, according to the discharge container 10 according to the present embodiment, the contents in the container body 11 can be transferred from either the first discharge hole 14 or the second discharge hole 32 by changing the operation method. It becomes possible to discharge, and the discharge mode can be easily changed.
Further, since the lid portion 16 restricts the opening of the second discharge hole 32 by the discharge valve 35, even if the container body 11 is unintentionally squeezed and deformed with the lid portion 16 attached, The contents can be prevented from being unexpectedly discharged from the two discharge holes 32.
Moreover, since the discharge valve 35 and the air valve 36 are integrally formed, the number of parts can be reduced. Furthermore, since the discharge valve 35 and the air valve 36 are integrally formed via the partition cylinder part 20, the structure can be simplified.

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

For example, the lid portion 16 may be attached to the mouth portion 12, and the lid portion 16 may not be provided.
In the above embodiment, the partition tube portion 20 forms the second discharge hole 32 between the outer tube portion 21 and the air hole 33 between the inner tube portion 22, but the present invention is not limited to this. I can't. For example, the partition cylinder part 20 may form the second discharge hole 32 between the inner cylinder part 22 and the air hole 33 between the outer cylinder part 21.
Further, the discharge valve 35 and the air valve 36 may not be integrally formed.

  Moreover, in the said embodiment, although the connection cap 13 and the mounting | wearing cap 37 are formed in the different body, this invention is not limited to this. For example, the connection cap 13 and the mounting cap 37 may be integrally formed.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
