SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has a simple structure, and a fixed amount of liquid can be poured out by a simple operation of erecting and inverting the container body. It is an object of the present invention to provide a dispensing container capable of dispensing.

[0004]

According to the first aspect of the present invention, there is provided a container body for accommodating a liquid, and a container provided in the container body, which is provided in the container body through an inlet when the container body is inverted. When the measuring chamber for introducing and quantitatively storing the liquid, the outlet formed at the bottom of the measuring chamber when the container main body is in the upright posture, the container main body is operated by buoyancy or gravity, and the container main body is inverted. The outlet port is closed and the outlet is opened when the container body is erected, and the open / close valve communicates with the outlet of the measuring chamber, and flows out from the outlet when the container body is erected. A liquid dispensing container comprising: a liquid reservoir for receiving a liquid to be discharged; and a spout for discharging liquid from the liquid reservoir when the container body is inverted. According to this invention, when the container main body is inverted, the liquid in the container main body flows into the measuring chamber via the inlet. At this time, in the case of a structure having a valve that operates by buoyancy, the valve receiving the buoyancy closes the outlet located above as the liquid level in the measuring chamber rises, and thus a fixed amount of liquid is stored in the measuring chamber. In the case of a structure provided with a valve that operates by gravity, the valve closes the outlet by gravity, so that a fixed amount of liquid is stored in the measuring chamber. Thereafter, when the container body is erected, the valve operated by buoyancy and the valve operated by gravity operate to open the outlet in any case, and the liquid in the measuring chamber flows into the liquid storage chamber. Therefore, a fixed amount of liquid is stored in the liquid storage chamber and is on standby. Next, when the container body is again inverted, the liquid stored in the liquid storage chamber is discharged from the spout. At the same time, the liquid in the container body flows into the measuring chamber through the inlet, and the next liquid is measured and stored. Therefore, with such a dispensing container, a fixed amount of liquid measured in the measuring chamber can be dispensed by simply operating the container body upright / inverted with one hand.

According to a second aspect of the present invention, there is provided a container main body for storing a liquid, a measuring chamber provided in the container main body, for introducing the liquid in the container main body through an introduction port and for quantitatively storing the liquid therein, When the main body is in the upright posture, the outlet formed at the upper end of the measuring chamber and operates by buoyancy or gravity, and when the container main body is erected, the outlet is closed and the container main body is inverted. Dispensing liquid for dispensing a fixed amount of liquid, comprising: an opening / closing valve for opening the outlet when the container is opened; and an outlet communicating with the outlet for discharging the liquid in the measuring chamber when the container body is inverted. Provide a container. According to the present invention, when the container body is in the upright posture, the liquid in the container body flows into the measuring chamber via the inlet. In the case of a structure provided with a valve that operates by buoyancy, as the liquid level in the measuring chamber rises, the valve that has received buoyancy closes the outlet located at the upper end of the measuring chamber, and thus stores a fixed amount of liquid in the measuring chamber. Also, in the case of a structure of a valve which operates by gravity, the valve closes an outlet located at the upper end of the measuring chamber by gravity, so that a fixed amount of liquid is stored in the measuring chamber. Thereafter, when the container main body is inverted, a valve operated by buoyancy or a valve operated by gravity operates to open the outlet in any case, so that the liquid in the measuring chamber is discharged from the spout. At this time, if the opening of the inlet is made small, the amount of the liquid in the container body flowing into the measuring chamber is extremely small, and the influence of the amount on the amount to be dispensed is extremely small and negligible. Therefore, with such a dispensing container, a fixed amount of liquid measured in the measuring chamber can be dispensed by simply operating the container body upright / inverted with one hand.

In a preferred application of the present invention, a water-soluble powder or granule and water are contained in a container body, and the water-soluble powder or granule is dissolved in water to form a saturated aqueous solution, and the water-soluble powder or granule is dissolved in water. An undissolved powder or granule is left to be stored in an amount larger than the amount, and the saturated aqueous solution is guided to the measuring chamber through the inlet. As described above, by storing the powder or the granules, even if the aqueous solution in the container body is poured out and disappears, the remaining powder or the aqueous solution is dissolved by replenishing the water to create the aqueous solution. be able to. Therefore, it is possible to replenish water as long as the powder or granules remain,
The number of dispensing can be increased. In this case, it is preferable that at least a part of the container body is configured such that the remaining amount of undissolved powder or granules remaining inside can be seen from the outside. In this way, the remaining amount of the powder or granules can be confirmed from the outside, so that it is easy to determine whether or not the powder or granules can be used and how much can be used. In this case, the state visible from the outside is transparent, colored transparent, translucent, or the like.

Another preferred application of the present invention is that the liquid, water-soluble powder or granules contained in the container body is a chlorine neutralizer which neutralizes residual chlorine contained in tap water, for example, L-ascorbic acid (vitamin). C), sodium L-ascorbate, calcium sulfite, sodium sulfite and the like. Recently, it has been pointed out that chlorine remaining in tap water is not good for skin and hair.Therefore, when using tap water for bathing, face washing, hand washing, washing dishes and food, etc. To neutralize residual chlorine in tap water. In response to such demands, the use of the metering container of the present invention makes it possible to pour out a necessary and appropriate amount of a chlorine neutralizer with a simple operation, and to remove residual chlorine contained in tap water. Can be neutralized. In the present invention, the upright / inverted posture of the container body is an upright state in which the liquid is not poured out from the spout, and the upright / inverted posture is a state in which the liquid flows out of the spout. Therefore, if the container main body is tilted so that the liquid is not discharged from the spout, the posture corresponds to the upright posture, and the posture in which the liquid flows out from the spout corresponds to the inverted posture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on a first embodiment shown in FIGS. FIG. 1 is a cross-sectional view of the whole in a state where the pouring container is erected, FIG. 2A is a cross-sectional view of a main part in a state where the pouring container is turned upside down, and FIG. FIG. 2C is a cross-sectional view of a main part in a state where the dispensing container is turned upside down once again. FIG. In the figure,
Reference numeral 1 denotes a container body, which is formed of a transparent resin such as PET and has a capacity of, for example, about 300 ml. The container body 1 contains a liquid 2 to be poured. In the case of the present embodiment, an aqueous solution 2 of a chlorine neutralizer, for example, L-ascorbic acid (hereinafter, referred to as vitamin C) is contained in the container body 1. In this case, the container body 1 contains vitamin C in the form of powder or granules 3 and also contains water. When the vitamin C granules 3 are poured into the container body 1 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 3 remain in the above water amount. So over-contained. Incidentally, the saturated solubility of vitamin C is said to be 25 to 30%. For example, if 200 g of vitamin C granules 3 are stored in the container body 1 and 300 ml of water is injected, about 100 g of vitamin C is dissolved. The rest remains as granules. As a result, 300 ml of the saturated aqueous solution 2 of vitamin C is stored in the container body 1.

An opening having a predetermined diameter is formed at the upper end of the container body 1 and a cap 4 is formed in the opening.
Is detachably attached by means such as screwing. The inner cylinder 5 is attached to the cap 4. When the cap 4 is attached to the container body 1, the inner cylinder 5
The lower end is provided with a strainer 6 made of a nonwoven fabric or the like. The strainer 6 prevents the undissolved vitamin C granules 3 from entering the inlet 9 described below when the container body 1 is inverted, but allows the aqueous solution 2 to pass through. The interior of the container body 1 is vertically divided.

A weighing unit 7 is provided integrally or integrally with the cab 4. The weighing unit 7
The measuring chamber 8 has a measuring chamber 8. The measuring chamber 8 is positioned upright as shown in FIG. 1, and the container main body 1 is inserted through an inlet 9 provided at an upper end of the measuring chamber 8. Leads to. When the container body 1 is in the upright posture, an outlet 10 is opened at a bottom portion below the measuring chamber 8. In the measuring chamber 8, a valve operated by buoyancy, for example, a ball-shaped float valve 11 is movably accommodated. When the float valve 11 is seated on the outlet 10, the outlet 10 is closed. The measuring chamber 8
Is provided with a regulating plate 12 having a mesh structure in order to prevent the float valve 11 from moving upward and closing the inlet 9. The measuring chamber 8 having such a structure has a capacity of 1
It is set so as to correspond to the amount of the aqueous solution required for each pouring. That is, the measuring chamber 8 controls the amount of the aqueous solution.
The dispensed amount of each time is measured. The outlet 10 formed at the bottom of the measuring chamber 8 communicates with the liquid reservoir 13. When the liquid storage chamber 13 and the container body 1 are in the upright posture, the liquid storage chamber 13 and the container main body 1 are formed so as to be located below the outlet 10 and have a volume larger than the internal capacity of the measuring chamber 8. I have. The liquid storage chamber 13 communicates with a pouring tube 14 provided at a position eccentric from the outlet 10, and the pouring tube 14 extends above the cap 4 through the cap 4. . The tip of the dispensing cylinder 14 is a spout 15
When the container main body 1 is turned upside down, the aqueous solution 2 is discharged from the spout 15.

The operation of the dispensing container according to the first embodiment having such a configuration will be described. As described above, the container body 1 contains the vitamin C aqueous solution 2 with the vitamin C granules 3 remaining. When the container body 1 is held upside down with one hand, the aqueous solution 2 flows through the strainer 6 and flows toward the cap 4. In this state, the aqueous solution 2 flows into the measuring chamber 8 through the inlet 9 as shown in FIG. When the aqueous solution 2 flows into the measuring chamber 8, the level of the aqueous solution rises, and the float valve 11 rises from the state shown by the imaginary line to the state shown by the solid line. When the float valve 11 comes into contact with the outlet 10, the outlet 1
0 is closed, so that the aqueous solution 2
Is stopped from entering. Next, when the container main body 1 is held up with one hand and returned to an upright position, the aqueous solution 2 in the container main body 1 returns to the bottom side of the container, and the inside of the measuring chamber 8 is shown in FIG. Thus, the float valve 11 is separated from the outlet 10 by buoyancy. Therefore, the outlet 10 is opened, and the aqueous solution 2 in the measuring chamber 8 flows into the liquid reservoir 13 through the outlet 10. As a result, the aqueous solution is temporarily retained in the liquid storage chamber 13, and the solution is to be poured. When the container body 1 is again turned upside down, as shown in FIG. 2C, the aqueous solution stored in the liquid storage chamber 13 is discharged from the outlet 15 through the outlet tube 14 to the outside. At this time, the aqueous solution in the container body 1 simultaneously flows into the measuring chamber 8 through the inlet 9, and this aqueous solution pushes up the float valve 11 by buoyancy and flows until the float valve 11 is seated in the outlet 10. When the float valve 11 closes the outlet 10, the flow of the aqueous solution into the measuring chamber 8 stops. This prevents the aqueous solution from flowing out of the measuring chamber 8 into the liquid storage chamber 13, and the next aqueous solution to be poured out is measured and stored in the measuring chamber 8. Thereafter, by repeating the above operation, the aqueous solution measured in the measuring chamber 8 is discharged from the outlet 15 each time.

According to the dispensing container of the above embodiment, a predetermined amount of the aqueous solution can be dispensed simply by inverting the container from an upright state with one hand, so that the dispensing operation is extremely simple. In addition, since the amount to be dispensed is measured in the weighing chamber 8, highly accurate dispensing can be performed. Further, the measuring unit 7 can be constituted by the measuring chamber 8, the float valve, the liquid storage chamber 13, the pouring cylinder 14, and the like, so that the structure is simple. In the case of the present embodiment, since the solution of vitamin C is used as the aqueous solution 2, it is effective for, for example, neutralizing chlorine in tap water stored in a bathtub. That is, tap water is mixed with chlorine for sterilization, and residual chlorine remains in the water stored in the bathtub. It has been pointed out that residual chlorine is not good for skin and hair, and therefore it is desired to neutralize residual chlorine when taking a bath. On the other hand, it is known that vitamin C has an action of reacting with chlorine to neutralize residual chlorine into harmless chlorine compounds. In this case, for example, if approximately 200 liters of tap water having a residual chlorine concentration of 1.0 ppm is stored, if about 2 ml of a saturated aqueous solution 2 of vitamin C is injected into this water, the residual chlorine is converted into a harmless chlorine compound. can do. In order to mix about 2 ml of the aqueous solution of vitamin C with one cup of water in the bath, the metering container of this embodiment is convenient. That is, if the amount measured in the measuring chamber 8 is set to 2 ml, the residual chlorine can be neutralized only by inverting the container once a day and pouring the aqueous solution into the bath water. And the capacity of the container body 1 is 300 m
1 allows about 150 uses and can be used for about 5 months. Further, when the aqueous solution is no longer present in the container body 1, water may be supplied. That is, since the undissolved vitamin C granules 3 remain in the container main body 1, the granules can be dissolved in water to form the aqueous solution 2. Thereby, the number of times of use is further increased. Whether or not undissolved vitamin C remains in the container can be confirmed from the outside because the container body 1 is transparent.

In the case of the first embodiment, an example is shown in which the float valve 11 using buoyancy is used to open and close the outlet port 10. However, a valve using gravity instead of the float valve may be used. It is feasible. That is, FIG. 3 shows a second embodiment, in which a weight 20 is used. Weight 2
Numeral 0 denotes a ball shape in which a steel ball is coated with a plastic (not shown). A valve chamber 21 is formed below the measuring chamber 8 with the container body 1 in an upright posture.
1 accommodates the weight 20. The valve chamber 21 communicates with the liquid storage chamber 13. The valve chamber 21 and the liquid storage chamber 1
A mesh regulating plate 22 for preventing the weight 20 from dropping into the liquid storage chamber 13 is provided at the boundary position 3.

The operation of the second embodiment having such a configuration will be described. When the container body 1 is held upside down with one hand, as shown in FIG. 3A, the weight 20 in the valve chamber 21 moves by gravity and abuts on the outlet 10 to close the outlet 10. In this state, the aqueous solution 2 in the container main body 1 flows into the measuring chamber 8 through the inlet 9, and when the aqueous solution 2 is full in the measuring chamber 8, the further entry of the aqueous solution 2 into the measuring chamber 8 is stopped. When the outlet 20 is closed by the weight 20, air remains in the measuring chamber 8, and this air may obstruct the inflow of the aqueous solution. To prevent this, when the weight 20 is seated on the outlet 10, the weight 20 and the outlet 1
It is good to make a gap where air escapes between 0. This gap allows the passage of air, but may be any small gap that cannot pass through the gap due to surface tension when the aqueous solution reaches the outlet 10. Next, when the container body 1 is erected, the weight 20 descends by gravity and moves away from the outlet 10 as shown in FIG. Therefore, the outlet 10 is opened, and the aqueous solution 2 in the measuring chamber 8 flows into the liquid reservoir 13 through the outlet 10. As a result, the aqueous solution is temporarily retained in the liquid storage chamber 13, and the solution is to be poured. And
When the container body 1 is again turned upside down, the aqueous solution stored in the liquid storage chamber 13 is discharged from the outlet 15 through the outlet tube 15 as shown in FIG. 3C. At the same time, the weight 20 closes the outlet 10, and in this state, the container body 1
The aqueous solution therein flows into the measuring chamber 8 through the inlet 9, and the aqueous solution to be discharged next is measured and stored in the measuring chamber 8. Therefore, in the case of the second embodiment as well, a predetermined amount of aqueous solution can be poured out simply by turning the container upside down from an upright state, and the pouring operation is extremely simple. In addition, since the amount to be dispensed is measured in the weighing chamber 8, highly accurate dispensing can be performed.

Next, a third embodiment will be described with reference to FIGS. In FIG. 4, reference numeral 31 denotes a container body, in which the liquid to be poured out,
For example, a vitamin C aqueous solution 2 is stored. In this case, too, the granules 3 of vitamin C are excessively contained so as to remain after dissolution. An opening having a predetermined diameter is formed at the upper end of the container main body 31, and a cap 32 is detachably attached to this opening by a means such as a screw-in type. A pouring cylinder 33 penetrates and is attached to the cap 32, and a pouring port 34 is opened at an outer end of the pouring cylinder 33. The inner end of the dispensing cylinder 33 is extended to the bottom of the container body 31, and a measuring chamber 35 is integrally formed at the tip. The measuring chamber 35 is located near the inner bottom of the container body 31 and is partitioned from the inside of the container body 31.
It communicates with the inside of the container body 31 via the inlet 36.
The inlet 36 is a hole having an inner diameter of about 1 to 4 mm. The measuring chamber 35 accommodates a valve operated by buoyancy, for example, a ball-shaped float valve 37. This float valve 3
Numeral 7 is adapted to move up and down as the liquid level in the measuring chamber 35 moves up and down.
Outlet 38 formed at the connection between the upper end of the cylinder and the discharge cylinder 33
, Whereby the upper end of the measuring chamber 35 is closed. When the float valve 37 is seated on the outlet 38 and closes the measuring chamber 35, the volume of the measuring chamber 35 is set to be a predetermined capacity. In order to prevent the remaining vitamin C granules 3 from entering the inlet 36 and closing the inlet 36, the outer periphery of the measuring chamber 35 is formed of a net or a mesh sheet. A strainer 39 is provided. The strainer 39 may be configured as a water-permeable partition wall positioned above the inlet 36 to partition the container body 31 up and down.

The operation of the dispensing container according to the third embodiment having such a configuration will be described. When the container body 31 is in the upright state, the vitamin C aqueous solution 2 in the container body 1 flows into the measuring chamber 35 through the inlet 36 as shown in FIG. In the measuring chamber 35, the float valve 37 is located at the bottom of the measuring chamber 35 as indicated by an imaginary line when there is no aqueous solution, but as the aqueous solution 2 flows in and the liquid level rises, the float valve 37 also becomes To rise. Then, as shown by the solid line, when the float valve 37 comes into contact with the outlet 38, the outlet 38 is closed. When this state is reached, the flow of the aqueous solution 2 into the measuring chamber 35 is stopped, and a predetermined amount of the aqueous solution 2 is stored in the measuring chamber 35.
When the container main body 31 is held upside down with one hand, the float valve 3 is set in the measuring chamber 35 as shown in FIG.
7 moves from the position shown by the imaginary line by the buoyancy as shown by the solid line, thereby opening the outlet 38. Therefore, the aqueous solution stored in the measuring chamber 35 is discharged to the outside from the outlet 34 through the outlet tube 33. At this time, the aqueous solution attempts to flow into the measuring chamber 35 through the inlet 36. However, when the outer periphery of the measuring chamber 35 is surrounded by the air remaining in the container body 31, the aqueous solution does not flow, and Even if the aqueous solution flows into the measuring chamber 35 through the inlet 36, the amount of inflow is extremely small because the opening area of the inlet 36 is small, and there is no problem that the measured liquid amount is affected. When the aqueous solution in the measuring chamber 35 is poured out in this way, if the container main body 31 is erected, the aqueous solution in the container main body 31 flows into the measuring chamber 35 from the inlet 36 again, and the next discharging is performed. Weighing and waiting for Therefore, even in the third embodiment,
It is possible to pour out a predetermined amount of aqueous solution only by inverting the measuring container by one-handed operation from the upright state, and the pouring operation is extremely simple. In addition, since the amount to be dispensed is measured in the measuring chamber 35, high-precision quantitative dispensing becomes possible.

In the third embodiment, an example is shown in which the float valve 37 using buoyancy is used. However, a valve using gravity instead of the float valve can be used.
That is, FIG. 6 shows a fourth embodiment, in which a weight 40 is used. The weight 40 has a ball shape in which a steel ball is coated with a plastic (not shown). In this case, a valve chamber 41 is formed above the measuring chamber 35 with the container body 31 in an upright posture, and the weight 40 is accommodated in the valve chamber 41. This valve chamber 41 communicates with the discharge tube 33. The valve chamber 41 is provided with a mesh regulating plate 42 for regulating the movement of the weight 40.

In the case of the fourth embodiment having such a structure, when the container main body 31 is in the upright state, the weight 40 in the valve chamber 41 moves by gravity as shown in FIG. Then, it comes into contact with the outlet 38 and closes the outlet 38. In this state, the aqueous solution 2 in the container body 31 flows into the measuring chamber 35 through the inlet 36, and a predetermined amount of the aqueous solution 2 is stored in the measuring chamber 35. In this case as well, the outlet 40 is connected to the weight 40 by the weight 40.
There is a concern that the air in the measuring chamber 35 will not escape due to the blockage. However, in order to prevent this, when the weight 40 is seated on the outlet 38, the air between the weight 40 and the outlet 38 is It is a good idea to make a space for the escape. This gap allows the passage of air, but the aqueous solution may be a minute gap that cannot pass through the gap due to surface tension. Next, when the container main body 31 is turned upside down, the weight 40 descends by gravity and moves away from the outlet 38 as shown in FIG. For this reason, the outlet 38 is opened, and the aqueous solution 2 in the measuring chamber 35 is discharged from the spout through the discharge chamber 33 through the valve chamber 41 to the outside. Therefore, also in the case of this embodiment, a predetermined amount of the aqueous solution can be poured only by inverting the container with one hand from the upright state, and the pouring operation is extremely simple.

In each of the above embodiments, an example is described in which a solution of vitamin C is used as an aqueous solution, but the present invention is not limited to an aqueous solution. Further, the valve using buoyancy and the valve using gravity are not limited to the float valve and the weight of each of the above embodiments, and various types of opening / closing valve structures can be implemented as long as buoyancy or gravity is used. It is.

[0020]

As described above, according to the present invention, a fixed amount of liquid measured in the measuring chamber can be poured out by operating the pouring container upside down with one hand from the upright state, and the pouring operation can be greatly improved. A simple and simple structure enables quantitative control of the dispensed amount with high accuracy.
