  Hereinafter, a method of using the mixing and discharging container 1 of the present embodiment will be described. In the mixing / discharging container 1, by attaching the operation unit 3 to the base unit 2, the protrusion (the tip end 22 a of the mouth 22 in this example) provided on the base unit 2 is changed to the bottom wall 38 of the housing 32. And the second contents B in the storage portion 32 (the second storage space S2) flow into the pouch container portion 21 (the first storage space S1).

  Specifically, first, the lid part 26 is removed from the base part 2 shown in FIG. Next, as shown in FIG. 3, the operation section 3 is disposed above the base section 2 such that the distal end portion 22 a of the mouth section 22 of the base section 2 is inserted into the inside of the inner cylindrical section 48 of the operation section 3. At this time, the connecting tube portion 33 of the operation section 3 is arranged on the outer peripheral side of the connected tube portion 24 of the base portion 2. In addition, the outer tube 25 of the base 2 is arranged on the outer peripheral side of the connection tube 33 of the operation unit 3.

  When the operation unit 3 is rotated around the axis O with respect to the base unit 2, the male screw portion 24 a of the connected tube portion 24 and the female screw portion 33 a of the connection tube portion 33 are screwed together, and the base portion 2 is operated. The part 3 approaches. In the process, the tip portion 22a of the mouth portion 22 comes into contact with the bottom wall portion 38 and is strongly pressed, so that the breaking portion 40 is broken.

  As shown in FIG. 4, when the break portion 40 breaks, a hole is formed in the bottom wall portion 38, and the second content B in the storage portion 32 flows into the pouch container portion 21 by its own weight. At this time, even when the front end portion 22a of the mouth portion 22 is closed by the bottom wall portion 38, since the notch 23 is formed in the mouth portion 22, the flow path of the second content B is secured. In this way, the first content A and the second content B are stored in the first storage space S1 of the pouch container 21 and are in a mixable state.

  In the present embodiment, the first content A and the second content B are easily mixed by repeatedly squeezing the pouch container 21 from the outside so that the pouch container 21 is easily reduced in volume. Can be. By mixing the first content A and the second content B, a mixed content C is obtained as shown in FIG.

  Then, as shown in FIG. 5, when the nozzle head 34 is unscrewed from the holding portion 51, the nozzle head 34 is pushed upward by the urging force of the coil spring 47, and a pump-up state in which the nozzle head 34 can be pushed down. Then, by repeatedly pushing down the nozzle head 34, the mixed content C in the first storage space S is sucked up by the action of the pump unit 35, passes through the mouth 22, the second storage space S2, and is moved into the cylinder unit. The liquid is discharged from the discharge port 34a to the outside through the inside of the stem 39 and the stem 42 and further through the nozzle 34e. With the discharge of the mixed contents C, the volume of the pouch container 21 gradually decreases, and when the mixed contents C is discharged to the end, the pouch container 21 has a completely crushed shape.

  As described above, the mixing and discharging container 1 of the present embodiment has a configuration in which the first content A and the second content B are mixed in the pouch container portion 21 that is easily reduced in volume. By repeatedly kneading the pouch container portion 21, the first content A and the second content B can be easily mixed. Therefore, even when the first content A and the second content B are liquids that are hardly mixed with each other, for example, when the first content A is a liquid having a relatively large viscosity, the mixed content C is reliably removed. Obtainable. Further, since the press-down pump type discharge device 30 is employed, even when the viscosity of the mixed content C is high, the mixed content C can be reliably discharged by operating the pump unit 35.

  Further, when starting to discharge the mixed content C, the air existing in the first storage space S1 can be sent out to the outside by squeezing the pouch container 21 to reduce the head space. Further, when the remaining amount of the mixed content C is low, the mixed content C remaining in the first storage space S1 can be squeezed out by squeezing the pouch container portion 21, and the amount of the remaining mixed content C can be reduced.

  The second content B preferably has a lower viscosity than the first content A. According to this, the movement when the second content B flows into the pouch container portion 21 from the storage section 32 is prevented. Become smooth.

  The present invention is not limited to the above embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention. For example, the pump section 35 is not particularly limited as long as the pump section 35 can suck up the contents from the pouch container section 21 and discharge the contents from the discharge port 34a by pressing down the nozzle head 34. Further, in the above-described embodiment, the connection tubular portion 33 and the connected tubular portion 24 are configured to be screw-coupled. However, the present invention is not limited thereto, and the connecting tubular portion 33 and the connected tubular portion 24 are provided on any one side. The convex portion provided on the other side may fit into the concave portion. In this case, when attaching the operation section 3 to the base section 2, the connecting cylinder section 33 and the connected cylinder section 24 are aligned and pushed in the axial direction to be attached. Further, in the above-described embodiment, the bottom wall portion 38, the connecting tubular portion 33, and the inner tubular portion 48 are formed as an integral member, but the present invention is not limited to this.
