  As shown in FIG. 6, in the inverted state of the discharge container 1, the introduction hole X is located at the lower end portion of the accommodation space S (near the mouth portion 11 and immediately above the check valve 90). It communicates with the accommodation space S. In addition, as shown in FIG. 6, in the inverted state of the discharge container 1, the lower end opening 32 a of the tube member 32 is located at the upper end portion (near the bottom portion 13) of the accommodation space S, and therefore is located outside the content liquid. Become.

  Here, as shown in FIG. 6, in the inverted state of the discharge container 1, the valve body 103 in the adapter 102 is lowered downward by its own weight and is in contact with the valve seat surface of the valve seat 101. Therefore, the lower end opening 32a of the tube member 32 serving as one introduction hole is not communicated with the accommodation space S through the notch 104 and is closed.

  Therefore, when the discharge container 1 is turned upside down and the body 12 of the container body 10 is squeezed (see the white arrow in FIG. 6), the content liquid is introduced from the introduction hole X and the valve body 103 of the valve member 100 is By closing the lower end opening 32a of the tube member 32, the liquid content liquid ("D" shown in FIG. 6) is discharged from the front end opening 66a of the nozzle 66 without introducing air from the lower end opening 32a. Can do. In addition, when discharging the content liquid into a liquid state, it can be discharged intermittently (drop-like) or continuously (linearly) as shown in FIG. It is.

  As shown in FIG. 7, the content liquid introduced from the introduction hole X (see the one-dot chain line arrow in FIG. 7) is a flow path Y, a gap Z, and a gap formed between the holding member 33 and the cylinder member 31. It flows into the mixing chamber 34 through the flow path G. Further, as described above, in the inverted state shown in FIG. 7, air does not flow into the mixing chamber 34 from the flow path W of the tube member 32. Therefore, the content liquid that has flowed into the mixing chamber 34 through the introduction hole X flows into the nozzle 66 through the flow port 57a of the mounting cap 50 and the flow-in / out hole 68 of the nozzle head 60, and becomes liquid from the tip opening 66a of the nozzle 66. Discharged.

  As described above, according to the discharge container 1 of the present embodiment, it is possible to realize foam discharge of the content liquid by using the discharge container 1 in an upright state, and to use the discharge container 1 in an inverted state. Thus, liquid discharge of the content liquid can be realized, and the state of the discharged content liquid can be changed according to the intended use and purpose.

  In particular, in the discharge container 1 of the present embodiment, the introduction hole X is formed to communicate with the position of the upper end portion of the accommodation space S in the upright state. By doing so, when the discharge container 1 is turned upside down, the introduction hole X leads to the position of the lower end portion of the accommodation space S, so that it is not introduced into the introduction hole X when used in the upside down state. The content liquid can be eliminated or reduced. Furthermore, the discharge container 1 of the present embodiment is formed so that the lower end opening 32a of the tube member 32 communicates with the position of the lower end portion of the accommodation space S in the upright state. By doing so, since the lower end opening 32a leads to the position of the lower end portion of the accommodation space S in the upright state of the discharge container 1, the content that is not introduced into the lower end opening 32a when used in the upright state. The liquid can be eliminated or reduced.

  The discharge container according to the present invention is not limited to the configuration specified in the above-described embodiment, and various modifications can be made without departing from the gist of the invention described in the claims. For example, one introduction hole of the present embodiment is configured by the lower end opening 32a of the tube member 32 that is a separate body from the cylinder body 36 (see FIG. 1 and the like), but is not limited to this configuration. For example, the partition member may be integrally formed and two introduction holes may be formed in a part of the partition member. Further, the valve member 100 of the present embodiment is configured by the cylindrical adapter 102 and the spherical valve body 103 (see FIG. 1 and the like), but is not limited to this configuration, It can be appropriately changed according to the size.

  ADVANTAGE OF THE INVENTION According to this invention, the discharge container which can be switched by simple operation between discharge by the foam-like state of content liquid and discharge by a liquid state can be provided.
