An upper check valve 46 (ball valve in this example) is provided on the inner peripheral surface of the stem 42 to prevent the internal solution from flowing back downward. The piston 41 is urged upward by an urging member (a coil spring in this example) 47, thereby urging the depressed nozzle head 34 upward to return to its original position.

In this example, a cover member 50 fixed to the upper end portion of the cylinder portion 39 is provided. As shown in FIG. 2 , the cover member 50 includes a holding portion 51 for engaging and holding the nozzle head 34 pushed down toward the pump portion 35 , and extending below the holding portion 51 so as to cover the cylinder of the pump portion 35 . and a grasping tube portion 52 surrounding the periphery of the portion 39 . The gripping tube portion 52 is positioned between the nozzle head 34 and the housing portion 32 . Further, the grasping cylinder portion 52 of this example has substantially the same outer diameter as the peripheral wall 34b of the nozzle head 34, the side wall portion 36 of the accommodating portion 32, and the connecting cylinder portion 33, and in the state shown in FIG. 3 is configured to have a columnar shape. Annular convex ribs 53 are provided on the outer peripheral surface of the gripping tube portion 52 at two locations in the axial direction. The convex rib 53 makes it difficult to slip when gripping the cylindrical grip portion 52 . In other words, when carrying the mixing/discharging container 1 or the operation part 3 alone, or when pushing down the nozzle head 34, the grip cylinder part 52 is configured to be easily gripped.

Further, the grasping tube portion 52 linearly extends along the axis O from the upper end connected to the holding portion 51 to the lower end located in the vicinity of the housing portion 32 . The holding portion 51 is composed of a tubular portion having a diameter smaller than that of the holding tubular portion 52, and is provided with a male screw portion 51a on its outer peripheral surface. A female threaded portion 34f that can be engaged with the male threaded portion 51a of the holding portion 51 is provided on the inner peripheral surface of the peripheral wall 34b of the nozzle head 34 .

The nozzle head 34 can be put into the stored state shown in FIG. As a result, the operation unit 3 can be downsized, and efficiency during distribution and storage can be improved.

The connecting tube portion 33 is cylindrical and protrudes downward from the bottom wall portion 38 . A female threaded portion 33 a that can be engaged with the male threaded portion 24 a of the connected tubular portion 24 is provided on the inner peripheral surface of the connecting tubular portion 33 . An inner tubular portion 48 protruding downward from the bottom wall portion 38 is provided radially inward of the connecting tubular portion 33 so as to surround the breaking portion 40 .

The operation unit 3 of this example is configured to be in an inverted posture in which the top surface 34g of the nozzle head 34 is grounded so that the second content B can be easily injected into the second accommodation space S2. Specifically, the nozzle head 34 is formed so that the outer edge of the top surface 34g constitutes a substantially flat surface, so that the nozzle head 34 can easily stand on its own in an inverted posture with the top surface 34g grounded. In addition, it is preferable that a gently curved concave portion is formed in the central portion of the top surface 34g so that a finger can be easily placed on the nozzle head 34 when the nozzle head 34 is pushed down.

Further, in this example, the bottom wall portion 38 of the storage portion 32 is formed separately from the side wall portion 36, and after the second content B is injected into the second storage space S2, the bottom wall portion 38 is formed on the side wall portion 36. It is configured so that the wall portion 38 can be attached. In other words, after the second content B is poured into the second accommodation space S2 with the operation unit 3 in an inverted posture and the bottom wall 38 not attached, the bottom wall 38 can be attached to the side wall 36, thereby making it easy to operate. The second content B can be enclosed in the second containing space S2 at the same time. The bottom wall portion 38 is provided with an engaging tubular portion 38a that engages with the engaged portion 36a provided on the lower outer peripheral surface of the side wall portion 36, and a sealing tubular portion 38b that contacts the lower inner peripheral surface of the side wall portion 36. It is

Below, the usage method of the mixing discharge container 1 of this embodiment is demonstrated. By attaching the operating portion 3 to the base portion 2 of the mixing/discharging container 1 , the protrusion provided on the base portion 2 (in this example, the tip portion 22 a of the mouth portion 22 ) touches the bottom wall portion 38 of the housing portion 32 . is broken, and the second content B in the storage portion 32 (second storage space S2) flows into the pouch container portion 21 (first storage space S1).

Specifically, first, the lid portion 26 is removed from the base portion 2 shown in FIG. 1 to open the mouth portion 22 . Next, as shown in FIG. 3 , the operation portion 3 is arranged above the base portion 2 by inserting the tip portion 22 a of the mouth portion 22 of the base portion 2 into the inner cylindrical portion 48 of the operation portion 3 . At this time, the connecting tubular portion 33 of the operating portion 3 is arranged on the outer peripheral side of the connected tubular portion 24 of the base portion 2 . Further, the outer cylindrical portion 25 of the base portion 2 is arranged on the outer peripheral side of the connecting cylindrical portion 33 of the operating portion 3 .

Then, when the operating portion 3 is rotated around the axis O with respect to the base portion 2, the male thread portion 24a of the connected tubular portion 24 and the female thread portion 33a of the connecting tubular portion 33 are screwed together, and the base portion 2 and the operating portion 2 are operated. Part 3 is approaching. In the process, the tip portion 22a of the mouth portion 22 abuts and is strongly pressed against the bottom wall portion 38, thereby breaking the breaking portion 40. As shown in FIG.

As shown in FIG. 4, when the breaking portion 40 is broken, a hole is formed in the bottom wall portion 38, and the second content B in the containing portion 32 flows into the pouch container portion 21 due to its own weight. At this time, even if the tip portion 22a of the mouth portion 22 is blocked by the bottom wall portion 38, the passage of the second content B is secured because the notch 23 is formed in the mouth portion 22. FIG. In this manner, the first content A and the second content B are accommodated in the first accommodation space S1 of the pouch container portion 21 and are ready to be mixed.

In this embodiment, since the pouch container part 21 is easily deformed and reduced in volume, the first content A and the second content B can be easily mixed by repeatedly squeezing the pouch container part 21 from the outside. can be done. By mixing the first content A and the second content B, a mixed content C is obtained as shown in FIG.

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 to enter a pump-up state in which a push-down operation is possible. By repeatedly pushing down the nozzle head 34, the mixed content C in the first accommodation space S is sucked up by the action of the pump portion 35, passes through the mouth portion 22 and the second accommodation space S2, and flows into the cylinder portion. 39 and the inside of the stem 42, and further through the nozzle 34e, and are discharged to the outside from the discharge port 34a. As the mixed content C is discharged, the pouch container portion 21 is gradually reduced in volume and deformed, and when the mixed content C is discharged to the end, the pouch container portion 21 is completely crushed.

As described above, in the mixing and discharging container 1 of the present embodiment, the first content A and the second content B are mixed in the pouch container portion 21 that can be easily reduced and deformed. By repeatedly kneading the pouch container part 21, the first content A and the second content B can be easily mixed. Therefore, even if the first content A and the second content B are liquids that are difficult to mix with each other, such as when the first content A is a liquid with a relatively high viscosity, the mixed content C can be reliably mixed. Obtainable. Moreover, since the push-down pump type discharger 30 is employed, even when the mixed content C has a high viscosity, the mixed content C can be reliably discharged by operating the pump section 35 .

Further, when starting to discharge the mixed content C, the pouch container portion 21 is squeezed up to expel the air present in the first housing space S1 to the outside, thereby reducing the head space. Moreover, when the mixed content C is running out, the pouch container part 21 is squeezed up to squeeze out the mixed content C remaining in the first accommodation space S1, thereby reducing the residual amount.

In addition, the second content B preferably has a lower viscosity than the first content A. According to this, the movement of the second content B when flowing from the storage portion 32 into the pouch container portion 21 is reduced. becomes smooth.

It goes without saying that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. For example, the pump part 35 is not particularly limited as long as it can suck up the contents from the pouch container part 21 by pushing down the nozzle head 34 and discharge it from the discharge port 34a. In the above-described embodiment, the connecting tube portion 33 and the connected tube portion 24 are screwed together, but this is not the only option. A configuration may be adopted in which a convex portion provided on the other side is fitted into the concave portion provided on the other side. In this case, when the operating portion 3 is attached to the base portion 2, the connecting tubular portion 33 and the connected tubular portion 24 are aligned with each other and pushed in the axial direction. Moreover, in the above-described embodiment, the bottom wall portion 38, the connecting tube portion 33, and the inner tube portion 48 are formed as an integral member, but the present invention is not limited to this.
