Description

[Detailed explanation of the idea]

The present invention relates to drug dispensing containers. More specifically, in flush toilets and the like that use a flush tank, it is possible to quantitatively discharge a chemical solution such as an aromatic cleaning agent solution by utilizing the vertical movement of the water surface in the flush tank, and The present invention relates to a container that does not leak and has a simple structure and is therefore inexpensive. BACKGROUND ART In recent years, flush toilets have become extremely popular, and various products for cleaning toilet bowls and drain pipes, scenting, etc. are on the market. One example is a type that is liquid at room temperature and contains fragrances, surfactants, and pigments. However, when this liquid type is immersed in cleaning water in a flush tank, the amount of medicine discharged depends on the water depth of the container in which it is set. That is, the appropriate amount of liquid is often not discharged depending on the conditions under which the container is set, and if the angle at which the container is set is inappropriate, there are drawbacks such as liquid leakage. Therefore, for this purpose, a container has recently been proposed in which a solid drug is dissolved in washing water at room temperature and the solution is quantitatively discharged. As an example, Kimiaki Sane
Examples include those disclosed in Publications No. 44-5100 and Publication Utility Model Publication No. 49-38143. However, the former has the disadvantage that when it is immersed in the flushing water in the flush tank, the solution leaks from the side opening, and all of the chemical solution is discharged into the flush tank when the flushing water is discharged. Therefore, the amount dissolved in the flush water depends on the interval between toilet uses. That is, if you use the toilet frequently, the amount dissolved will decrease. Furthermore, like the former, the latter also has the disadvantage that the amount of drug dissolved depends on the frequency of use. The present inventor completed the present invention as a result of intensive research to obtain a drug dispensing container that does not have the above-mentioned drawbacks. That is, the present invention comprises a drug chamber, a liquid inlet/output pipe provided at the upper end of the drug chamber, and a drug liquid elevating tube, and the upper end of the liquid inlet/outlet pipe is higher than the upper end of the drug chamber and the drug liquid The present invention provides a drug dispensing container that is located lower than the upper end of the elevator tube. DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the drug dispensing container of the present invention shown in the drawings will be described. FIG. 1 is a longitudinal sectional view of one embodiment of the drug dispensing container of the present invention, in which 1 is a drug chamber, 2 is a liquid inlet/output pipe, 3 is a drug liquid elevator tube, A liquid inlet/outlet tube 2 and a drug liquid elevating tube 3 are provided at the upper end. To explain the embodiment in more detail, the cross-sectional shape of the liquid inlet/outlet tube 2 is not particularly limited, but in the case of a circular shape,
Its inner diameter a is preferably 1 to 10 mm, more preferably 2 to 5 mm. Further, the cross-sectional shape of the drug liquid elevator tube 3 is not particularly limited, but if it is circular, the inner diameter b is preferably 3 to 20 mm, more preferably 5 to 15 mm.
mm. In addition, the upper end 4 of the liquid inlet/output pipe 2 must be located lower than the upper end 5 of the drug liquid elevating tube 3, and the height difference H regulates the amount of drug liquid to be discharged. , and this height difference H
The amount of drug liquid discharged is determined by the cross-sectional area of the drug liquid elevator tube 3. Next, the manner in which the drug dispensing container having the above structure is used in a flush toilet will be explained with reference to FIGS. 2 and 3. When using such a container, attach the container to the upper edge of the flush tank (not shown) of a flush toilet using a hanger part (not shown).
Then, as shown in FIG. 2, the upper end 5 of the chemical liquid elevating tube 3 is set above the water surface W. In this state, a portion of the washing water flowing into the drug chamber 1 from the liquid inlet/output pipe 2 dissolves the drug, forming a saturated solution of the drug. In the state shown in Fig. 2, when the use (drainage) of purified water begins, the level of the purified water decreases, and the level of the chemical solution lift pipe 3 also decreases, which causes the liquid level in the chemical chamber 1 to decrease. A predetermined amount of drug-saturated liquid is pushed out from the liquid inlet/output pipe 2 and discharged into the flush tank.
Then, as shown in FIG. 3, when the water level of the chemical liquid elevating tube 3 reaches the same level as the upper end 4 of the liquid inlet/output tube 2, the ejection of the chemical liquid ends. When water is supplied after draining and the water level W reaches the upper end 4 of the liquid inlet/outlet pipe, water flows into the chemical chamber 1 from the liquid inlet/outlet pipe 2 and raises the water level of the chemical liquid elevator tube 3. Water supply ends in the state shown in FIG. Then, the medicine in the medicine chamber 1 is dissolved to form a saturated liquid, which is ready for the next use (drainage) of the purified water. FIG. 4 is a longitudinal sectional view of another embodiment of the drug dispensing container of the present invention, which is basically the same as that shown in FIG. In order to make this as small as possible, the cross-sectional area of the upper part of the chemical liquid elevating tube 3 is made small, and the error in the amount of the chemical liquid discharged due to fluctuations in the water level is suppressed to a small level. Figures 5 and 6 show how the container shown in Figure 4 is used in a flush toilet. Figure 5 shows the state before drainage, and Figure 6 shows the state after drainage. This figure shows a state in which the drug liquid has been discharged. The basic container operation is the same as shown in FIGS. 2 and 3. FIG. 7 is a longitudinal cross-sectional view of yet another embodiment of the drug dispensing container of the present invention, in which the upper tip portions of the liquid inlet/output tube 2 and drug liquid elevating tube 3 of the container shown in FIG. 1 are shaped like an inverted U. It is something. The drug dispensing container of this embodiment can be used by completely submerging the entire container in purified water, and has the advantage that it can be used regardless of the depth of the water as long as it is submerged. How this container is used in a flush toilet will be explained with reference to FIGS. 8 and 9. FIG. 8 shows a state in which the toilet is suspended by a hanger part (not shown) from the upper edge of the flush tank of a flush toilet and is submerged in water when it is full of water. In this state, a portion of the wash water flowing into the drug chamber 1 from the liquid inlet/outlet pipe 2 dissolves the drug, forming a saturated solution of the drug. In addition, because the liquid inlet/output pipe 2 and drug liquid elevator tube 3 have inverted U-shaped tips, even if the entire container is submerged in water, air still exists in the inverted U-shaped portion, and the height of the drug solution can be maintained regardless of the water depth. It is kept constant. When purified water is used (drained) in the state shown in FIG.
A predetermined amount of drug-saturated liquid in the tank is pushed out from the liquid inlet/output pipe 2 and discharged into the flush tank. Then, as shown in FIG. 9, when the water level of the chemical liquid elevating tube 3 reaches the same level as the water level of the liquid inlet/output pipe 2, the ejection of the chemical liquid ends. Then, when the drainage is completed and water is supplied, and the water level reaches the upper end 4 of the liquid inlet/output pipe or higher, water flows into the chemical chamber 1 from the liquid inlet/outlet pipe 2,
The water level in the chemical liquid elevator tube 3 is raised and the water supply is completed in the state shown in FIG. As described above, the drug dispensing container of the present invention discharges a fixed amount of drug liquid in which a solid drug is dissolved when purified water is drained, and a substantially constant amount of drug is dispensed almost regardless of the standing time. This is also clear from the following experimental examples. Experimental Example 1 Using the drug dispensing container shown in FIG. 1, the relationship between the standing time and the amount of drug dispensed was investigated. The volume of the drug chamber of the container used was 90 ml, the dimensions of a, b, and H were as shown in Table 1, and the amount of drug was 60 g. The results are shown in Table 1.

[Table] Experimental Example 2 Experiments were conducted using the container shown in Figure 7 while varying the water depth, and the results are shown in Table 2. The volume of the drug chamber 1 of the container shown in FIG. 7 was 90 ml, and the amount of drug was 60 g. As is clear from Table 2, it was confirmed that the discharge amount was hardly affected by water depth, and no change in discharge amount due to water depth was observed.

[Table] As mentioned above, the drug dispensing container of the present invention can be particularly preferably used in flush toilets, and according to the container of the present invention, a certain amount of water can be introduced into the drug chamber 1 when purified water rises. The medicine is dissolved in the medicine chamber 1, and when the purified water descends, a certain amount of the medicine is pumped through the liquid inlet/output pipe 2 due to the pressure difference between the medicine liquid elevating pipe 3 and the medicine liquid in the liquid inlet/outlet pipe 2. In addition to the remarkable effect of being able to discharge a certain amount of medicine along with purified water, it is easy to handle and has a simple structure, so the cost is low. Since the chemical is discharged only when the purified water is drained, the amount of chemical discharged is less than that of a type that disperses the chemical throughout the entire body, making it economical.Since there are no moving parts, there are extremely few troubles, and there is no need to worry. When the drug dispensing container is set in a flush tank such as a flush toilet, it can dispense a fixed amount of drug regardless of the water depth, and its structure means that there is almost no risk of liquid leakage, and its structure is not affected by water pressure. Since it is hardly affected, it is effective in not requiring much consideration for the strength and structure of container hanger parts, and its practical value is extremely high.
