2. Description of the Related Art As a conventional fragrance cleaning liquid drop container for flush toilets, the one described in Japanese Utility Model Publication No. 6-34457 is known. In this fragrance cleaning liquid drop lower container, the water injected from the currant is guided to the mixing case where the fragrance cleaning liquid and water are mixed, and the float valve is pushed up in response to the rise in the water level in the mixing case to release the bottle of fragrance cleaning liquid. A hole opens, and at the same time, the pressurized air in the mixing case is sent into the bottle, and when the water injection from the currant stops, the float valve is lowered and the aroma cleaning liquid is discharged from the bottle into the mixing case. Then, when water injection starts again from the currant, the aroma cleaning liquid mixed with water in the mixing case is drained from the drain port of the mixing case to the hand washing part.

[0003]

However, in the case of the aroma cleaning liquid drop lower container described in Japanese Utility Model Publication No. 6-34457, there is a problem that the structure is complicated and the manufacturing cost is high. Further, since the aroma cleaning liquid is easily solidified, the float valve is easily clogged. In addition, the replacement of the aroma cleaning liquid in the bottle with the air in the mixing case often does not proceed smoothly due to fluctuations in water pressure and the like, which causes a problem that the discharge amount of the aroma cleaning liquid is not constant.

On the other hand, an object of the present invention is to provide a drug discharge container capable of stably discharging a drug with a simple mechanism which does not require a manufacturing cost.

[0005]

In order to achieve the above object, the present invention provides a drug tank for containing a liquid drug, a nozzle projecting from the bottom of the drug tank and having a drug discharge hole at the tip, and a tip of the nozzle. Provided is a medicine ejection container, which comprises a medicine retaining tank into which a portion is inserted, and the medicine retaining tank is provided so that the medicine ejection holes are immersed in the medicine accumulated in the medicine retaining tank.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the drawings. In each drawing, the same reference numerals represent the same or equivalent constituent elements.

FIG. 1 shows a medicine discharge container 1 according to one embodiment of the present invention.
00A is a perspective view (a) and a sectional view (b) of FIG.
[Fig. 6] is a sectional view showing the action of the medicine ejection container 100A.

This medicine discharge container 100A is provided with a medicine tank 1 containing a liquid medicine A such as a toilet fragrance, a cleaning agent and a bactericide, and is detachably provided at the bottom of the medicine tank 1. It is composed of a nozzle 2 protruding from the bottom and a drug storage tank 4 fixed to the base of the nozzle 2 by adhesion or fitting.

A medicine ejection hole 3 is opened at the tip of the nozzle 2. The medicine A is held in the medicine discharge hole 3 by the surface tension, or as shown in the figure, the medicine A leaked from the medicine discharge hole 3 due to a change in ambient temperature or the like is accumulated in the medicine holding tank 4. The medicine tank 1 is also provided with feet 5.

In the present invention, the drug A has a viscosity of 5
It is preferable to use the one adjusted to ~ 1000 mPa · s (20 ° C), and the diameter of the drug ejection hole 3 is 1 to 5 mm.
It is preferable that If the viscosity of the drug A is too high or the hole diameter is too narrow, the drug A is difficult to be led out from the drug tank 1 to the tip of the drug discharge hole 3. On the contrary, drug A
If the viscosity of the medicine is too low or the diameter of the medicine is too wide, the medicine A excessively leaks from the medicine discharge hole 3 and the medicine A is discharged from the medicine holding tank 4.
Is more likely to overflow.

The tip of the nozzle 2 is inserted into the medicine retaining tank 4, and the medicine ejection hole 3 is provided so as to be immersed in the medicine A accumulated in the medicine retaining tank 4. Here, the drug ejection hole 3
Is not in contact with the bottom surface of the drug storage tank 4.

The inner diameter L1 of the medicine holding tank 4 is 5 from the point of the hole diameter of the water intake 21 (see FIG. 2) of the low tank of the flush toilet.
It is preferable to set it to ˜15 mm. Also, the drug storage tank 4
In the medicine tank 1, the distance L2 between the bottom surface of the medicine discharge hole 3 and the medicine discharge hole 3 is 0.5 to 3 mm, and the depth L3 from the medicine discharge hole 3 to the opening surface of the medicine holding tank 4 is 5 to 15 mm. It is preferable from the viewpoint of preventing excessive dripping of the drug A due to expansion of air.

As a method of using the medicine ejection container 100A, first, as shown in FIG. 2 (a), the medicine ejection container 100 is filled with the medicine A.
Hand wash part 20 of low tank with hand wash of flush toilet
Place on. In this case, the tip of the nozzle 2 is the hand washing part 2.
It fits into the water intake 21 of the low tank which is open at 0.

When the water in the flush toilet is flushed and the water W is supplied from the currant, as shown in FIG. 2B, the water W flows along the outer surface of the medicine tank 1 to the hand washing section 20 and the water suction port 21. It flows into the inside, and further flows so as to wash the inside of the medicine holding tank 4. Therefore, the medicine A held in the medicine ejection hole 3 or the medicine A accumulated in the medicine holding tank 4 is certainly exposed to the water W and enters the raw tank together with the water.

When the water supply from the currant is stopped, the flow of the water that empties the medicine A held in the medicine discharge hole 3 or the medicine A accumulated in the medicine holding tank 4 is stopped, and the medicine A is also supplied to the low tank. Stop. The inside of the medicine tank 1 becomes a negative pressure according to the amount of the medicine A supplied into the low tank, but the medicine A diluted with water and the air enter the medicine tank 1, so that the inside of the medicine tank 1 is always The pressure returns to or is maintained at a weak negative pressure state, and the medicine holding tank 4 remains in a state in which the medicine A diluted with water remains accumulated (FIG. 2C).

Thereafter, this action is repeated every time water is supplied from the currant, and the medicine A is mixed in the raw tank.

By the way, when the medicine discharge container 100X is composed of only the medicine tank 1 and the nozzle 2 as shown in FIG. 6 without providing the medicine holding tank 4, if the temperature of the water supplied from the currant is lower than the ambient temperature. When the water supplied from Karan hits the drug tank 1 (in a summer toilet, etc.), the drug tank 1 is first cooled and contracts, so that the drug A drips from the drug ejection hole 3 accordingly. afterwards,
Over time, the air in the drug tank 1 gradually warms up,
When the temperature returns to room temperature, the medicine A drips again due to the expansion of the air in the medicine tank 1.

On the contrary, when the water temperature is higher than the air temperature (prone to occur in a toilet in winter, etc.), the water in the medicine tank 1 is expanded by the water and the air in the medicine tank 1 is expanded.
Drips.

Therefore, the discharge amount of the drug from the drug discharge container may fluctuate due to the temperature difference between the water temperature and the air temperature, and the drug may be discharged unnecessarily in large amounts.

On the other hand, the medicine discharge container 100 of the present invention
In A, since the medicine ejection holes 3 are present in the liquid accumulated in the medicine holding tank 4, it is difficult to replace air in the medicine tank 1 and liquid dripping is unlikely to occur.

The medicine discharge container 100A has a very simple structure and has a small number of constituent parts. Drug tank 1,
The nozzle 2 and the drug storage tank 4 can be easily manufactured by plastic molding. Therefore, this medicine ejection container 100A can be obtained at low cost. Further, the medicine A can be surely mixed into the low tank by supplying water from the currant, and at that time, the medicine A does not spread to the hand washing section 20, so that the hand washing section 20 is not contaminated with the medicine A. Further, the medicine A is the nozzle 2
Can be filled at any time by removing from the medicine tank 1.

As a method of discharging the medicine, a porous material is provided at the bottom of the medicine tank, the medicine is permeated into the porous material, and the porous material is added to the water collected in the hand washing part when flushing the flush toilet. Although it is possible to consider the method of exposing to water, the chemical exuded from the porous material does not directly enter the raw tank and spreads to the hand washing part, which causes a problem of soiling the hand washing part.

FIG. 3 is a perspective view (a) and a sectional view (b) of a medicine ejection container 100B according to another embodiment of the present invention. This medicine ejection container 100B is the medicine ejection container 100A of FIG.
On the other hand, the pinhole 6 which is a minute hole is formed on the peripheral surface of the medicine holding tank 4, and the others are formed in the same manner.

Regarding the size of the pinhole 6, the liquid accumulated in the medicine holding tank 4 is retained in the pinhole 6 by the surface tension in a stationary state, but the vigorous water supplied from the currant is not It is preferable that the pinhole 6 can be moved in and out, and more specifically, the diameter of the pinhole is 0.5 to 1 mm.

As a result, the liquid stored in the medicine holding tank 4 is easily replaced by the water supplied from the currant, so that the amount of the medicine A mixed in the raw tank can be increased.

The above-mentioned medicine ejection containers 100A and 100B
Is to discharge the medicine A from the medicine discharge hole 3 without applying a special pressure to the medicine A in the medicine tank 1. However, the present invention is A mode in which the medicine A is ejected from the ejection hole 3 is also included.

FIG. 4 shows such a drug discharge container 100C.
FIG. 5 is a perspective view of FIG. 5, and FIG. 5 is a cross-sectional view showing its action.

The medicine discharge container 100C is constructed by stacking a water storage tank 7 on the medicine tank 1. An inlet 8 is provided at the top of the water storage tank 7 so that the water W supplied from the currant above the water storage tank 7 enters the water storage tank 7 as shown by the arrow in FIG. Further, the water storage tank 7 is provided with a drain port 9 for draining the water W stored in the water storage tank 7 from the bottom of the water storage tank 7 to the outside. The drain port 9 is always open. The size and the number of the drainage ports 9 are appropriately determined such that the water that has entered the water storage tank 7 from the inlet port 8 continues to be drained from the drainage port 9 and still accumulates in the water storage tank 7.

On the other hand, the medicine tank 1 is provided at its top with an elastic portion 10 made of a dome-shaped rubber member which is deformed by a pressing force according to the amount of water stored in the water storage tank 7. The medicine tank 1 itself is formed so as not to substantially deform so that the pressure inside the medicine tank 1 increases due to the deformation of the elastic portion 10.

A nozzle 2 projects from the bottom of the medicine tank 1, and a medicine ejection hole 3 is opened at the tip of the nozzle 2. A medicine holding tank 4 is attached so as not to come into contact with the medicine ejection hole 3. . The medicine ejection container 100A shown in FIG.
Similarly to the above, the medicine A is held in the medicine discharge hole 3 by the surface tension, or, as shown in FIG.
The medicine A leaking from the medicine ejection hole 3 due to a change in ambient temperature is accumulated in the medicine holding tank 4.

As a method of using the medicine discharge container 100C, in a state where the medicine A is filled in the medicine tank 1, first, the medicine discharge container 100C is placed on the hand washing section 20 of the low tank with hand washing of the flush toilet (FIG. 5 (a)). ).

When the flush toilet flushes the water and the water W is supplied from the currant as shown by the arrow, the water is drained from the drain port 9 but is still stored in the water storage tank 7 as shown in FIG. 5B. The water will be stored. The elastic portion 10 gradually deforms due to the weight of the water stored in the water storage tank 7,
When the amount of stored water exceeds a certain amount, the elastic portion 10 is crushed, the internal pressure of the medicine tank 1 is increased, and a certain amount of the medicine A is discharged from the medicine discharge hole 3 to the medicine holding tank 4. On the other hand, the water supplied from the currant, which has come off the inlet 8 and the water drained from the drain 9, flows along the outer surface of the chemical tank 1 into the hand washing section 20, flows into the water inlet 21, and It flows like washing the inside of the medicine holding tank 4. Therefore, the medicine A discharged from the medicine discharge hole 3 and accumulated in the medicine holding tank 4 is certainly exposed to the water W and enters the raw tank together with the water. It should be noted that depending on the momentum of the water W flowing into the water inlet 21, the mounting structure of the medicine holding tank 4, etc.
Even when the water W flowing into 1 does not enter the medicine holding tank 4, the discharged medicine A can be overflowed from the medicine holding tank 4 due to the deformation of the elastic portion 10 and can enter the raw tank.

When a predetermined amount of water is supplied from the currant, the supply of water from the currant stops, but after that, the water W stored in the water storage tank 7 is drained from the drain port 9. When the water W stored in the water storage tank 7 flows out, the force with which the water storage tank 1 pushes the elastic portion 10 is weakened, and the elastic portion 10 is restored to its original shape. At this time, since the inside of the medicine tank 1 has a negative pressure, the medicine A or air diluted with water enters the medicine tank 1 through the medicine discharge hole 3, and the inside of the medicine tank 1 returns to normal pressure or a weak negative pressure. The pressure is maintained, and the medicine holding tank 4 remains in a state where the medicine A diluted with water remains (FIG. 5C).

Thereafter, this action is repeated every time water is supplied from the currant, and the medicine A is mixed in the raw tank. Thus, by pressurizing the inside of the medicine tank 1, the medicine A is
Even if the medicine is discharged, if the medicine holding tank 4 is not provided, the medicine A is apt to unnecessarily drip from the medicine discharge hole 3 due to a change in the outside temperature, etc., but in the medicine discharge container 100C, Since the medicine ejection holes 3 are present in the liquid accumulated in the medicine holding tank 4, it is difficult for air to be replaced in the medicine tank 1 and it is difficult for the liquid to drip.

Various other modes can also be adopted in the case of discharging the medicine A by applying pressure to the medicine A in the medicine tank 1. For example, as the elastic portion 10, an elastic member such as a plastic bellows or a metal coil spring may be used in addition to the dome-shaped rubber member as long as it is deformed by the increase of the pressing force and restored by the decrease of the pressing force. Good.
