2. Description of the Related Art Recently, it has been pointed out that chlorine (residual chlorine) mixed in tap water for the purpose of sterilization stimulates skin and hair and is not good for skin and hair. Therefore, in the case of bathing, face washing, hand washing, washing dishes and foods using tap water, it is desired to mix a chlorine neutralizer with tap water to neutralize residual chlorine in tap water. As a chlorine neutralizer, L-
It is known that ascorbic acid (vitamin C), sodium ascorbate, calcium sulfite, sodium sulfite and the like are effective. For example, vitamin C has the effect of reacting with chlorine to neutralize residual chlorine into harmless chlorine compounds. In this case, the concentration of residual chlorine in the bathtub is 1.0 p.
Assuming that approximately 200 liters of tap water of pm is stored, if about 2 ml of a vitamin C aqueous solution is injected into this water, residual chlorine can be converted into harmless chlorine compounds. Various means can be considered for mixing about 2 ml of an aqueous solution of vitamin C with a bath of water (hot water). For example, a dispenser with a pump, which is known as a container for dispensing a shampoo solution or a rinse solution, can be used. is there. This device has a structure in which a push-type pump is attached to a gap for closing the upper end of a container body, and a predetermined liquid is discharged from a spout by pushing down the head of the pump. However, this has the drawback that the structure of the pump is complicated and the cost is high, and also has the trouble that the pump must be depressed each time it is used.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a structure in which it is put into and pulled out of the water. The purpose of this change is to provide a constant-volume dispensing container for liquids that can be poured into water, which allows the liquid to be poured out into the fixed quantity of water by this change in posture, and that can be poured out with a simple operation. is there.

[0004]

According to a first aspect of the present invention, there is provided a container body having an accommodation chamber for accommodating a liquid, wherein the container main body has an upright posture when in the air and an inverted posture when put in water. A weighing chamber provided in the container main body, for introducing the liquid in the storage chamber through the introduction port and quantitatively storing the liquid therein, and an atmosphere communication formed at a lower end of the weighing chamber when the container main body is in the upright posture. A mouth and a spout communicating with the upper end of the measuring chamber,
A weight valve that is housed in the measuring chamber, closes the air communication port by the action of gravity when the container body is in the upright posture, and opens the air communication port when the container body is inverted; And a float valve that opens the spout when the container body is inverted by generating buoyancy by the liquid introduced into the measuring chamber through the introduction port when the container body is in the upright posture and closing the spout. And a container for dispensing a fixed amount of liquid underwater which is provided.

According to the present invention, when the container body is in the upright posture (in the air), the weight valve in the measuring chamber closes the air opening passage extending downward by contacting the air communication port.
The liquid in the storage chamber flows into the measuring chamber through the inlet. This liquid gives buoyancy to the float valve in the measuring chamber, and when a predetermined amount of liquid is reached, the float valve closes the spout, so that a fixed amount of liquid is stored in the measuring chamber. Next, when the container body is inverted (underwater), the weight valve receiving the gravity separates from the air communication port and opens the air communication port which is upward in this case. At the same time, the float valve separates from the spout and the spout is opened. For this reason, the liquid in the measuring chamber is discharged into the water via the outlet. When the container body is again erected, a fixed amount of liquid is stored in the measuring chamber by the action of the weight valve and the float valve, and the apparatus stands by as the next pouring. Therefore, with such a dispensing container, a fixed amount of liquid measured in the measuring chamber can be dispensed simply by throwing it into or pulling it up into water to erect / invert the container body.

A preferred application of the present invention is that the weight valve opens the air communication port and closes the introduction port when the container body is inverted. With this configuration, it is possible to prevent the liquid in the storage chamber from flowing into the measuring chamber through the introduction port while the liquid measured in the measuring chamber is discharged outside through the discharge passage. Another preferred application is to provide a float or a weight on the container body so that when the container body is put into water, the float or the weight automatically causes the container body to be in an inverted posture.

Another preferred application of the present invention is that the liquid contained in the container body is a chlorine neutralizer that neutralizes residual chlorine contained in tap water, for example, L-ascorbic acid (vitamin C), L-ascorbin. Sodium sulfite, calcium sulfite, sodium sulfite and the like. With such an application, the necessary amount of the chlorine neutralizer can be poured out with a simple operation, and it is included in tap water for bathing, face washing, hand washing, washing dishes and food, etc. Residual chlorine can be neutralized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the drawings. This embodiment is a bath vitamin C used for neutralizing residual chlorine by mixing an appropriate amount of an aqueous vitamin C solution for neutralizing residual chlorine contained in water (including hot water) stored in a bathtub with water. Fig. 1 is an example of application to a container for dispensing a fixed amount of an aqueous solution. Fig. 1 is a cross-sectional view of a state in which the container is pulled up into the air and is in an upright posture. FIG. 3 is a cross-sectional view of a state in which the handset is inverted. In the figure, reference numeral 1 denotes a container main body, which is formed, for example, in a spherical shape with a heat-resistant transparent resin. The container body 1 is in the upright posture shown in FIG. 1, and has an air chamber 2 formed at a lower position and a storage chamber 3 formed at an upper position. The air chamber 2 has a sealed structure, which is a float. The storage chamber 3 stores an aqueous solution 4 of vitamin C. In this case, the storage chamber 3 stores vitamin C in the form of powder or granules 5 and water. When the vitamin C granules 5 are poured into the storage chamber 3 until the water is almost full before the start of use, the amount of the water cannot be completely dissolved, that is, the undissolved vitamin C granules 5 remain in the above amount of water. Over-contained. By the way, the saturated solubility of vitamin C is 25-30%
For example, if 200 g of vitamin C granules 5 are accommodated in the accommodation room 3 and 300 ml of water is injected, about 100 g of vitamin C is dissolved and the rest remains as granules. Thereby, 300 ml of the saturated aqueous solution 4 of vitamin C is stored in the storage chamber 3.

The storage chamber 3 is provided with a water supply port 6, which is closed by a plug 7. If the vitamin C aqueous solution in the storage chamber 3 runs out, water can be supplied from the water supply port 6. The accommodation room 3 is provided with an atmospheric pressure correction port 8. When the pressure in the accommodation room 3 falls below the atmospheric pressure, the atmospheric pressure is introduced through the atmospheric pressure correction opening 8, and the accommodation room 3 is set to the atmospheric pressure. To keep it. In this air pressure correction port 8,
A breathable sheet 9 is provided which allows the passage of air but prevents the passage of water or an aqueous solution of vitamin C.

A measuring chamber 10 is provided in the container body 1. The measuring chamber 10 is in the upright posture shown in FIG.
It is provided so as to be located at the lower part of the accommodation room 3 and communicates with the accommodation room 3 through the inlet 11. Therefore, the aqueous solution 4 in the storage chamber 3 flows into the measuring chamber 10 through the inlet 11. In the posture shown in FIG. 1, the lower end of the measuring chamber 10 communicates with the atmosphere opening passage 12, and the atmosphere opening passage 12 penetrates downward through the center of the container main body 1 and is open to the lower end of the container main body 1. The measuring chamber 10 and the atmosphere opening passage 12
Is formed at a boundary portion of the air passage 13 in the shape of a valve seat. In the same manner, in the posture of FIG.
The upper end of 0 is communicated with the pouring passage 14, which penetrates upward through the center of the container body 1 and is open to the upper end of the container body 1. A valve seat-shaped outlet 15 is formed at the boundary between the measuring chamber 10 and the outlet passage 14.

In the measuring chamber 10, a weight valve 16 which is located at the lower side in the posture of FIG. 1 and moves by the action of gravity is accommodated. The weight valve 16 is in the form of, for example, a ball in which a steel ball is resin-coded, and
Open and close. In the measuring chamber 10, a float valve 17, which is also located at the upper side in the posture of FIG. 1 and moves by receiving buoyancy by the liquid flowing into the measuring chamber, is accommodated.
The float valve 17 has, for example, a ball shape filled with air, and opens and closes the outlet 15. Further, a regulating plate 18 having a mesh or a porous structure for dividing the measuring chamber 10 into upper and lower portions is provided in the measuring chamber 10. The regulating plate 18 regulates the range of movement of the weight valve 16 and the float valve 17, but has water permeability so as not to hinder the permeation of water. In this case, the regulating plate 18 is installed obliquely, and acts as a guide for the weight valve 16. That is, as shown in FIG. 2, when the weight valve 16 is in contact with the regulating plate 18, the weight valve 16 is guided to one side, and the weight valve 16 is brought into contact with the introduction port 11 so that the liquid introduction port 11 is closed. It is configured to close. Note that a strainer 19 is provided outside the measuring chamber 10.
Is provided. The strainer 19 prevents the undissolved vitamin C granules 5 remaining in the storage chamber 3 from flowing out to the measuring chamber 10 through the inlet 11 and prevents the vitamin C granules 5 from blocking the inlet 11. is there. When the container body 1 is pulled out of the bathtub and left in the air, the container body 1 is placed on a receiving stand 20 shown in FIG. 1, and the container main body 1 placed on the receiving stand 20 has an upright posture. Can be maintained.

The operation of the embodiment having such a configuration will be described. When the container body 1 is left in the air, as shown in FIG.
In this state, the aqueous vitamin C solution 4 in the storage chamber 3 flows into the measuring chamber 10 through the inlet 11. At this time, in the measuring chamber 10, the weight valve 16 closes the air communication port 13 due to gravity, so that the aqueous solution is stored in the measuring chamber 10. When the amount of the aqueous solution in the measuring chamber 10 increases, the water level rises, so that the float valve 17 rises from the state shown by the imaginary line to the state shown by the solid line. When the float valve 17 hits the spout 15, the spout 15 is closed. As a result, a fixed amount of the aqueous solution is stored in the measuring chamber 10. For example, when mixing an aqueous solution of vitamin C with bath water, if about 2 ml of the aqueous solution is required each time, the amount stored in the measuring chamber 10 may be set to be about 2 ml.

Next, when the container main body 1 is put into bath water, the container main body 1 is provided with a float constituted by the air chamber 2, so that the container main body 1 is submerged in water by the buoyant action of the float. It becomes an inverted posture as shown in FIG.
In this inverted posture, since the float valve 17 is in the aqueous solution in the measuring chamber 10, it generates buoyancy and rises as shown by the solid line, so that the spout 15 is opened. On the other hand, the weight valve 16 is separated from the atmosphere communication port 13 by gravity, so that the upper end of the measuring chamber 10 is opened to the atmosphere through the atmosphere opening passage 12. For this reason, the aqueous solution stored in the measuring chamber 10 is discharged from the discharge passage 1.
4 and will be mixed with the bath water. In particular, in the case of an aqueous solution of vitamin C, the specific gravity is higher than that of water.
The aqueous solution of vitamin C in 0 quickly sediments through the pouring passage 14 and mixes with the bath water. At this time, the weight valve 16
Is located at a position where it is guided by the regulating plate 18 and closes the introduction port 11, thereby preventing the vitamin C aqueous solution from flowing from the storage chamber 3 into the measuring chamber 10. Therefore, the measuring chamber 1
The aqueous solution weighed at zero will be dispensed.

When the dispensing is completed in this manner, the container body 1 is pulled up from the water, and is placed on the receiving stand 20 in an upright posture, so that the lower end of the measuring chamber 10 is closed by the weight valve 16. The aqueous solution of No. 3 is stored in the measuring chamber 10, and the aqueous solution is stored until the float valve 17 closes the upper end. Therefore, it waits until a fixed amount of the aqueous solution is next discharged in the measuring chamber 10.

According to the dispensing container of such an embodiment, a predetermined amount of the aqueous solution can be dispensed simply by holding the container body 1 with one hand and throwing it into water or pulling it up.
Operation is extremely simple. In addition, the dispensed amount is measured in the measuring chamber 10.
, So that highly accurate quantitative dispensing becomes possible. In addition, when the aqueous solution tries to flow from the storage chamber 3 to the measuring chamber 10, the storage chamber 3 becomes a negative pressure, so that an outflow resistance occurs.
In the case of the embodiment, since the air pressure correcting port 8 is provided, the generation of the negative pressure is prevented, so that the aqueous solution in the storage chamber 3 can be smoothly supplied to the measuring chamber 1.
Flows to zero. In addition, the aqueous solution in the storage chamber 3 decreases with each injection, and when the capacity of this room is, for example, 300 ml, about 150 uses can be performed. However, the aqueous solution disappears after about 5 months of use. At this time, if water is supplied from the water supply port 6, the undissolved vitamin C remaining in the accommodation chamber 3
The aqueous solution 3 can be prepared by dissolving the granules 5 in water. This further increases the number of uses. Note that whether or not undissolved vitamin C remains in the storage chamber 3 can be confirmed from the outside because the container body 1 is formed transparent.

In the case of the above-described embodiment, the weight valve 16 is set while the aqueous solution stored in the measuring chamber 10 is being discharged through the discharge passage 14.
Although the introduction port 11 is configured to be closed, the opening of the introduction port 11 may not be closed by the weight valve 16 when the opening is small. That is, when the aqueous solution measured in the measuring chamber 10 is poured out, if the opening of the inlet 11 is small, the inlet 1
The amount of liquid leaking from the storage chamber 3 to the measuring chamber 10 through 1 is very small, and this amount can be accepted within an error range. Therefore, the introduction port 11 does not have to be closed by the weight valve 16. Further, when the water surface of the aqueous solution 4 in the storage chamber 3 is lower than the position of the inlet 11 in the posture shown in FIG. 2, the aqueous solution does not leak from the storage chamber 3 to the measuring chamber 10. The inlet 11 does not have to be closed by the weight valve 16. In the above embodiment, when the container body 1 is underwater, the posture of the container is held upside down by the float including the air chamber 2, but a floating member may be used instead of the air chamber 2, Alternatively, a weight may be attached to the opposite position of the container body 1 so that the weight is on the lower side to maintain the posture of the container. In addition to using these floats and weights, for example, the container body is suspended by a chain, etc., and is suspended in an inverted posture when put in water, and is placed in an upright posture when pulled up from the water. You may do so. Further, in the above embodiment, the measuring chamber 10 is formed inside the container main body 1. However, the measuring chamber may be formed outside the container main body, and the atmosphere opening passage 12 and the discharging passage 14 are formed in the center of the container main body 1. The passages 12 and 14 may be formed outside the container main body 1, though the passages 12 and 14 are formed so as to penetrate the portion. Furthermore, in the above-described embodiment, the example in which the aqueous solution of vitamin C is mixed into the water in the bath tub is described. However, the present invention is not limited to this. It can be implemented as long as the liquid is poured out.
