〔Example〕

Hereinafter, embodiments of the medicine dispensing container of the present invention shown in the drawings will be described.

1, FIG. 2, FIG. 3, and FIG. 4 respectively show a front view, a left side view, a right side view and an enlarged vertical sectional view of an embodiment of the present invention. Is a solid medicine, 2 has a medicine chamber 3 in which the solid medicine 1 is accommodated, and a medicine accommodating portion having an opening 4 below the medicine chamber 3 and 5 is located above the medicine accommodating portion 2 and has an air vent hole. In the water storage unit having 6, the drug storage unit 2 and the water storage unit 5 are connected by a communication pipe 7 having a U-shape, and the connection position of the drug storage unit 2 and the communication pipe 7 is the drug chamber 3 The lower end of the communication pipe 7 having a U-shape and located above the solid medicine 1 is positioned lower than the solid medicine 1.

In more detail about the examples, as the solid drug 1,
A non-woven fabric, a water-soluble film, or the like, which is optionally wrapped with a cleaner, an antifouling agent, an aromatic agent, etc., is used. Further, the cross-sectional area of the lower portion of the medicine chamber 3 is equal to the solid medicine 1
Is smaller than the cross-sectional area of the medicine container 2 below the medicine chamber 3, and the end portion 8 of the communication pipe 7 branches into three at the joint with the medicine container 2 and faces downward. It is bent to open to the medicine chamber 3 of the medicine storage unit 2. or,
The opening 4 of the medicine container 2 opens downward at the lower end of the medicine container 2 so that water in a flash tank (not shown) can flow in and out. The opening 4
Is sufficient from the drug chamber 3 so that if the drug dispensing container is tilted, the solid drug 1 does not come into contact with water at times other than the necessary time described below, and thereby the dissolution of the solid drug 1 is not adversely affected. It is preferable to open at a distance.

The shape and size of each part of the medicine dispensing container are not particularly limited, but the following ranges are generally preferable. That is, the volume of the water reservoir 5 is 10 to 50 ml, the volume of the drug chamber 3 is 30 to 100 ml, and the inner diameter (diameter) a of the communication pipe 7 is 3 to.
10 mm, the inner diameter (diameter) b of the end 8 of the communication pipe 7 is 1 to 5 m
m, the diameter of the air vent hole 6 of the water reservoir 5 is 5 mm or more.
Also, the opening 4 may have a size that allows water to flow in and out,
Furthermore, the lower end of the communication pipe 7 having a U-shape is preferably lower than the lower end of the solid medicine 1 by 20 mm or more,
Desirably, it is located lower than the opening 4 as shown.

Next, a usage mode of the drug dispensing container configured as described above will be described based on FIGS. 5 to 9.

FIG. 5 shows a state immediately after the above-mentioned drug distribution container is installed (set) in a flash tank (not shown) by an appropriate attaching means such as a hanging tool, and the water level in the flash tank is the highest. In position. In this state, the solid medicine 1 is completely immersed in the water W. That is, at the time of setting, since water does not collect in the U-shaped portion of the communication pipe 7,
The water W from which the air in the medicine container 2 has flown in through the opening 4
Since it is pushed to the outside through the communication pipe 7 and the water reservoir 5 and escapes from the air vent hole 6, the water W
Infiltrate. As a result, the solid medicine 1 is also immersed in the water W,
Since buoyancy is not applied to the drug distribution container at the time of setting, the drug distribution container can be set smoothly. As described above, at this stage, the solid medicine 1 comes into contact with the water W, but once the water level in the flash tank is lowered, the solid medicine 1 is not changed when the water level rises or remains unchanged.
Does not come into contact with water W. This principle is as described below.

FIG. 6 shows the water W in the flash tank from the state of FIG.
Is discharged and the water level is lowered. In this state, water (hereinafter referred to as residual water) w remains in the communication pipe 7 in a U-shaped portion lower than the end portion 8 thereof.

Next, when the water level in the flash tank rises, the water W in the flash tank flows into the medicine distribution container through the opening 4, and as shown in FIG. The air is pushed by the pressure of the water W flowing in from the opening 4 and tries to escape from the air vent hole 6 to the outside through the communication pipe 7 and the water storage unit 5.
Since the presence of the residual water w in the interior becomes a resistance, it does not escape to the outside until the water level in the flash tank rises and the water W flows in from the air vent hole 6. As a result, at this stage,
The water W does not come into contact with the solid medicine 1.

The water level in the flash tank rises further and the air vent hole 6
When the water W flows in from, the state shown in FIG. 8 is obtained.

When the water W in the flash tank is discharged in the state shown in FIG. 8, the water level in the flash tank is lowered, the pressure balance in the medicine distribution container is lost, and the head pressure difference H is reduced as shown in FIG. As a result, air enters from the air vent hole 6 of the water storage unit 5 to lower the water level in the water storage unit 5, and the water W in the water storage unit 5 and the communication pipe 7 is discharged from the communication pipe 7 into the medicine storage unit 2. At this time, the water W discharged from the end portion 8 of the communication pipe 7 hits the solid medicine 1 stored in the medicine chamber 3, dissolves a part of the solid medicine 1, and the water W of the medicine storage unit 2 as a medicine solution. It is discharged into the flash tank through the lower opening 4. In this case, even if the water in the flash tank is discharged, the communication pipe 7 becomes a neck, and the water W
Does not act with the water W in the flash tank, and when most of the water W in the flash tank is discharged, or after all of it is discharged into the flash tank, and further into the toilet bowl, The water W containing the drug, that is, the drug solution is effectively used without being diluted with the water in the flash tank.

The discharge of the water W from the communication pipe 7 as described above ends when the state shown in FIG. 6 is reached. Then, as shown in FIG. 7, when the medicine distribution container is immersed in the water W, the water level does not rise above the vicinity of the opening 4 in the medicine container 2. As described above, this is because, as described above, there is no portion that communicates with the outside except the opening 4 and the end 8 of the communication pipe 7 in the medicine storage unit 2 and the outside is communicated due to the resistance of the residual water w in the communication pipe 7. Since the portion is blocked, the medicine storage unit 2 above the vicinity of the opening 4
This is because there is air inside. As a result, the solid medicine 1 stored in the medicine chamber 3 does not come into contact with the water W.

Although one embodiment of the medicine distribution container of the present invention has been described above, it goes without saying that the medicine distribution container of the present invention is not limited to this embodiment. For example, the end portion 8 of the communication pipe 7 may be a single piece as shown in FIGS. 14 and 15, may be located on the upper side of the medicine chamber 3, or may be detachably attached to the water storage portion 5 or the medicine storage portion 2. Can be configured to.
Further, as the form of the water storage section 5, the volume of the communication pipe 7 having a U-shape may be increased, and the water storage function may be included in the communication pipe 7 having a U-shape.
In addition, as for the manner of holding the solid medicine 1 in the medicine chamber 3, as shown in the above-mentioned embodiment and FIG.
This is not limited to the case where the cross-sectional area is smaller than the lower cross-sectional area, and as shown in FIGS. 11 and 12, a stopper 9 for holding the solid medicine 1 may be provided in the lower portion of the medicine chamber 3 or FIG.
As shown in FIG. 15, this can be carried out by detachably mounting a cartridge 11 having a large number of holes 10 for easily discharging the drug solution in the opening 4 of the drug container 2. In the embodiment of FIGS. 14 to 16, two kinds of solid medicines 1 (one is a compounding system of a surfactant and the other is a compounding system of a fragrance, a bactericide, etc.) are held in the cartridge 11. For example, when using the cartridge 11, the medicine storage unit 2
By making part of the structure removable, solid drug 1
Can be exchanged. Further, the opening 4 of the medicine container 2 may be opened laterally at the lower end of the medicine container 2, as shown in FIG. Also, the drug storage unit 2
The water storage unit 5 and the water storage unit 5 are not connected only by the communication pipe 7,
These can be integrally joined to the seat 12 as shown in FIGS. 1 and 12. The drug distribution container is usually molded from synthetic resin.
