Description

[Detailed description of the invention]

The present invention relates to a drug dispensing device in which two drug dispensing containers are integrally connected and each of the drug dispensing containers discharges a drug liquid at staggered ejection times. More specifically, by installing it in a flush tank of a flush toilet, etc., and utilizing the vertical movement of flush water in the flush tank, the time required to discharge a chemical liquid such as an aromatic cleaning agent from each chemical dispensing container can be reduced. By shifting and discharging quantitatively,
This invention relates to a drug dispensing device with a simple structure and low cost, which maximizes the effects of drugs. 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, these substances are more effective as fragrances than as cleaning agents. For this purpose, a drug dispensing container has recently been proposed in which a solid drug at room temperature is dissolved in washing water and the solution is quantitatively discharged. For example, Japanese Patent Publication No. 40-6031 and Japanese Patent Publication No. 49-32265
Examples include those disclosed in Publication No. However, while the former method is effective when the drug to be dispensed is insoluble in water and has a specific gravity lower than that of water, when using a drug that is soluble in water and has a higher specific gravity, the function of the drug dispensing container makes it difficult to use water. The internal agitation cannot be expected when the drug is taken in and out, and it is difficult to control the amount of medicine dispensed. In addition, the latter is unnecessary when the amount of medicine to be discharged is large because the stirring mode in the medicine dispensing container by the washing water during supply and drainage changes depending on the amount of medicine, causing a change in the amount of medicine to be discharged. The disadvantage is that the drug is ejected. Moreover, in such drug dispensing containers, when a drug consisting of components such as surfactants and pigments is used, the fragrance and color shading is only noticeable.
It only causes discomfort to the user. Incidentally, in recent years, the components of cleaning agents to be discharged include components containing active chlorine, which are generally known as disinfectant bleaches, such as sodium hypochlorite, calcium hypochlorite, potassium dichloroisocyanurate, and dichloromethane. Combination preparations of sodium isocyanurate, trichloroisocyanuric acid, chlorine dioxide, etc. are used. These ingredients are
Although it has an excellent cleaning effect, it is recognized that at high concentrations it can damage metals, rubber, etc. Therefore, when using the above-mentioned components as a cleaning agent to be discharged, the drug dispensing container is required to have the following functions. That is, firstly, there should be no leakage when left in the flash tank. Second, the amount of medicine discharged with respect to the vertical movement of the cleaning water is quantitative. Thirdly, it is required that the cleaning agent (sterilizing bleaching agent) be discharged quickly and that the amount remaining in the flush tank be extremely small. If the discharge container does not meet these conditions, the cleaning agent will remain in the flush tank longer than necessary, which will have an adverse effect on the metal, rubber, and other parts of the flush tank, and in the worst case, There is a fear that it may even affect its functionality. Therefore, as a drug dispensing container that satisfies the above-mentioned conditions, Utility Model Application No. 152338/1983 and Utility Model Application No. 58/1989
One example was proposed as No. 118323. However, although these drug dispensing containers have excellent functions, when multiple drug preparations are used, it is difficult to maximize the individual performance of these drug preparations and to maximize their synergistic effects. In addition to this, we are also working to functionally address the shortcomings of drug formulations, such as the damage to the metal and rubber parts of the flash tank when drug formulations containing active chlorine exceed a certain concentration as mentioned above. I can't. The present invention can maximize the individual and synergistic effects of multiple drug formulations used, and address the drawbacks of drug formulations, such as the above-mentioned active chlorine-containing ingredient drug formulations that exceed a certain concentration. Therefore, a drug dispensing device that can functionally address the drawbacks such as damage to the metal and rubber parts of the flush tank, that is, 2

A drug chamber for storing the drug preparation, and a drug solution in which a certain amount of water is introduced into the drug chamber when the water in the flash tank rises, and a drug liquid in which the drug preparation is dissolved when the water descends. It is equipped with a liquid inlet/output tube having a downward tip for discharging, and a drug liquid elevating tube having a downward tip located higher than the tip of the liquid inlet/outlet tube, and the liquid inlet/outlet tube of each liquid inlet/outlet tube A drug dispensing device characterized in that the positional relationship or the shape of the tip and the tip of the drug liquid elevating tube is changed so that the ejection times of the drug liquid discharged from each of the liquid inlet/output tubes are staggered. It provides: DESCRIPTION OF THE PREFERRED EMBODIMENTS The drug dispensing device of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows a perspective view of an embodiment of the drug dispensing device of the present invention used as a drug dispensing device for flush toilets. In the figure, A and B are drug dispensing containers, C is a fixing plate, and D is a fixing plate. The drug dispensing device of this embodiment is a hanger having a hook D' at the top.
It is made of synthetic resin and is formed by integrally bonding the drug dispensing containers A and B to a fixing plate C, and detachably bonding the fixing plate C to the lower end of the hanger D. As shown in detail in FIG. 2, the drug dispensing container A is constructed by integrally connecting a liquid inlet/output pipe 2 and a drug liquid elevating tube 3 to the upper part of a drug chamber 1 in communication with the drug chamber 1. There is. Both the liquid inlet/outlet tube 2 and the drug liquid elevating tube 3 have their tips facing downward, and the tip of the drug liquid elevating tube 3 is positioned higher than the tip of the liquid inlet/outlet tube 2. . still,
Although not shown, the drug dispensing container A is configured such that a drug preparation can be stored in a drug chamber 1 thereof so that the drug preparation can be taken in and out. In addition, in this embodiment, the drug dispensing container B is:
The drug dispensing container A has a symmetrical shape (structure), and each part of the drug dispensing container B is similar to the corresponding drug dispensing container A.
Each part is shown with a ``datsushi'' attached to the reference numerals indicating each part. In this embodiment, the drug dispensing containers A and B are integrally connected at different heights. That is, the opening 4 at the tip of the liquid inlet/outlet tube 2 of the drug dispensing container A and the opening 5 at the tip of the drug liquid elevating tube 3 are connected to the liquid inlet/outlet tube 2' of the drug dispensing container B, respectively.
It is located below the opening 4' at the tip of the drug liquid elevating tube 3' and the opening 5' at the tip of the drug liquid elevating tube 3'. This is to cause the drug liquid in the drug dispensing container B to be discharged more quickly than the drug liquid in the drug dispensing container A as described later. It is determined by the cross-sectional area and the difference a between the heights of the openings 4 and 5, and for the drug dispensing container B, it is determined by the difference a' between the heights of the drug solution elevator tube 3' and the openings 4' and 5'. It is made so that it will be done. The cross-sectional shape of the liquid inlet/outlet tube 2 of the drug chamber 1 of the drug distribution container A is not particularly limited, but in the case of a circular shape, the inner diameter b is preferably 2 to 6 mm, more preferably 3 mm. ~4 mm, and the cross-sectional shape of the drug liquid elevating tube 3 is also not particularly limited, but
In the case of a circular shape, its inner diameter c is preferably 3 to 20 mm,
More preferably, it is 5 to 15 mm. Further, the cross-sectional shape of the liquid inlet/outlet pipe 2' of the drug chamber 1' of the drug distribution container B is not particularly limited, but in the case of a circular shape, the inner diameter b' is preferably 3 to 8 mm, more preferably 4 to 7 mm; The cross-sectional shape of the drug liquid elevating tube 3' is not particularly limited either, but when it is circular, its inner diameter c' is preferably 3 to 15 mm, more preferably 5 to 10 mm. Next, the mode of use when the medicine dispensing device having the above structure is used in a flush toilet will be explained based on FIGS. 3 to 8. When using such a drug dispensing device, the drug dispensing device is hung from the upper edge of the flush tank (not shown) of a flush toilet using a hanger D, and the drug dispensing device is attached to drug dispensing containers A and B as shown in FIG. At the same time, the entire fixing plate C is submerged in water and set. For example, drug preparations containing fragrances and pigments are stored in the drug chamber 1 of the drug dispensing container A, and hypochlorite, which is a component containing active chlorine, is stored in the drug chamber 1' of the drug dispensing container B. Store calcium acid drug preparations. In the state shown in FIG. 3, part of the washing water W flowing into the drug chambers 1, 1' from the liquid inlet/output pipes 2, 2' dissolves the drug preparations 6, 6', forming drug liquids 7, 7'. It's forcing me. In addition, since the openings 4, 5, 4', 5' of the liquid inlet/output pipes 2, 2' and the drug liquid elevating tubes 3, 3' are opened downward, the drug distribution containers A, B
Even if the whole is submerged in water, air exists in each opening, and the heights of the liquid levels 8, 8' of the drug preparations 6, 6' remain constant regardless of the position of the water surface W' of the washing water W. It's dripping. When the washing water is used (drained) in the state shown in Fig. 3, the water level W' of the washing water W falls and the water surface
As shown in FIG. 4, when W' becomes less than the opening 5' at the tip of the drug solution elevator tube 3' of the drug distribution container B, the liquid level 8' of the drug solution 7' in the drug solution elevator tube 3' increases. Due to the difference in head pressure between the openings 4' of the liquid inlet and outlet pipes 2', the liquid level 8' of the drug liquid 7' falls, whereby the drug liquid 7' in the drug chamber 1' flows into the liquid inlet and outlet pipes. 2', and the drug liquid 7' is discharged. When the state shown in FIG. 5 is reached, the ejection of the drug liquid 7' in the drug distribution container B is completed, but the fourth
During the transition from the state shown in the figure to the state shown in FIG. , by the same principle as in the case of the drug dispensing container B, the above-mentioned drug liquid 7' in the drug dispensing container B.
The discharge of the drug liquid 7 in the drug dispensing container A is completed in the state shown in FIG. After the draining of the washing water W is completed, water is supplied, and the water surface W' of the washing water W reaches the liquid inlet/output pipe 2 of the drug dispensing container A.
At this point, as shown in FIG. 7, the cleaning water W flows into the drug chamber 1 of the drug dispensing container A while displacing the air present in the liquid inlet/outlet pipe 2, raising the liquid level 8 of the drug liquid elevator tube 3. raise. Then, as shown in FIG. 8, when the water surface W' of the washing water W further rises, the washing water W similarly flows into the drug dispensing container B. Then, the water supply ends in the state shown in Figure 3.
Drug dispensing containers A and B remain underwater. While standing, the drug formulation 6, 6' in the drug chamber 1, 1' gradually dissolves, ready for subsequent drainage. By the way, the drug formulation 6' stored in the drug dispensing container B is calcium hypochlorite, which is a component containing active chlorine, and since this calcium hypochlorite is effective in a small amount, it is difficult to discharge it. The amount may be small and should not remain in the flash tank as much as possible, while the drug dispensing container A
Since the drug formulation 6 housed in the container contains fragrances, pigments, etc., it is required to be dispersed in the last portion of the washing water W, and this requirement is met according to this embodiment. . That is, as mentioned above, the water level W' of the washing water W of the drug liquid 7' in the drug dispensing container B has fallen, and the opening 4' of the liquid inlet/outlet pipe 2' of the drug dispensing container B has been exposed to the air. Immediately after, the dispensing ends and the drug liquid 7 in the drug dispensing container A is discharged into the toilet bowl without being affected by the agitation caused by the water supplied from the upper part of the flush tank. Even after the drug liquid 7' has been ejected, it continues to be ejected and is stirred together with the water supply, unlike the drug liquid 7' from the drug dispensing container B.
A considerable amount of the perfume is dispersed in the wash water W and released into the toilet bowl, and the fragrance components and the like are effectively volatilized into the atmosphere by the movement of the wash water W inside the toilet bowl. Therefore,
According to this embodiment, the drug formulation 6' in the drug dispensing container B exhibits a cleaning effect, and the drug formulation 6 in the drug dispensing container A exhibits aromatic properties and functions as an indicator. If the inner diameter b of the liquid inlet/output pipe 2 of the drug dispensing container A is made smaller, the rate of descent of the drug liquid 7 in the drug dispensing container A in the drug liquid elevator tube 3 will be lower than that of the cleaning water during drainage. The water surface of washing water W can be lowered at a lower speed than the water surface W'
Even if the opening 4 of the liquid inlet/output pipe 2 of the drug dispensing container A is exposed to the air due to the drop of W', the drug dispensing container A
From then on, the chemical liquid 7 can be discharged for a while, so that the above-mentioned dispersion of the chemical liquid 7 into the washing water W can be made more effective. FIG. 9 shows another embodiment of the present invention,
In this embodiment, the drug dispensing containers A and B are symmetrically connected integrally at the same height, and the inner diameter b of the liquid inlet/output pipe 2 of the drug dispensing container A is connected to the liquid inlet/outlet pipe 2 of the drug dispensing container B. By making the inner diameter b' smaller than the inner diameter b' of the cleaning water W, the descending speed of the drug liquid 7' in the liquid inlet/output pipe 2 in the drug dispensing container A is significantly slower than the descending speed of the water surface W' of the washing water W. As shown in the experimental example, as in the previous embodiment, the ejection time of the drug liquid 7 from the drug dispensing container A and the ejecting time of the drug liquid 7' from the drug dispensing container B are staggered. FIG. 10 shows yet another embodiment of the present invention. In this embodiment, the drug dispensing containers A and B are not symmetrically shaped and are brought together in the vertical direction. It is designed to exhibit the same effect as the embodiment shown in the figure. In the above embodiment, two drug dispensing containers are used.
Although an example in which three or more drug dispensing containers are used has been described, it goes without saying that even if three or more drug dispensing containers are used, the drug dispensing device of the present invention can similarly eject drug liquids at staggered ejection times. Nor. Furthermore, in the drug dispensing device of the present invention, by combining the drug dispensing containers with different heights, or by changing the shape of the drug dispensing containers (dimensions of the liquid inlet/output tube, drug liquid elevating tube, etc.), It is only necessary that the drug liquid be ejected from each drug dispensing container at staggered ejection times. Example Using the drug dispensing device shown in FIG. 9, the relationship between discharge time and residual chlorine concentration was investigated. The result is the first
Shown in the table. The volumes of the drug chambers 1 and 1' of the drug dispensing device used were both 80 ml, and the dimensions of each part in FIG. 9 were as shown in Table 1. In addition, the drug formulation used 6,
The amount of 6' was 40 g, and the drug dispensing container A contained a surfactant-based drug preparation 6, and the drug dispensing container B contained a calcium hypochlorite-based drug preparation 6'.

[Table] As is clear from the results in Table 1, by discharging the drug liquid from drug dispensing container B in a shorter time than the ejecting time of the drug liquid from drug dispensing container A, the tank (flash tank) It can be seen that there is less residual chlorine in the tank. In addition, it is preferable that the effective chlorine concentration in the cleaning water remaining in the flush tank is 1 ppm or less in order to prevent damage to metals, etc. Further, the time required for ejecting the drug liquid from the drug dispensing container A is 3 to 4 seconds, which is enough to function as an indicator. As mentioned above, the medicine dispensing device of the present invention is particularly suitable for flush toilets, and when the flush water rises, a certain amount of flush water is introduced into each medicine chamber from the liquid inlet/output pipe. The drug formulation is dissolved in the washing water in the drug chamber, and when the washing water descends, multiple drug solutions can be discharged at staggered discharge times, maximizing the individual and synergistic effects of the multiple drug formulations used. It is functionally effective to overcome the drawbacks of drug formulations, such as damage to metal and rubber parts of flush tanks when drug formulations containing active chlorine exceed a certain concentration. In addition to being able to deal with
It is easy to handle, has a simple structure, and is inexpensive, which provides many advantages.
