The operation unit 44 is configured. By pressing and deforming the top surface portion 42 as the pressurizing operation portion 44, the volume of the measuring chamber 32 is reduced and the internal pressure of the measuring chamber 32 is increased.

That is, the pouring of the content liquid from the pouring port 25 of the pouring cap 20 to the measuring chamber 32 of the measuring cap 30 is stopped by the pouring control means 36 (pouring port opening / closing part 35), and the covering portion 40 is described as described above. The measuring chamber 32 is pressurized by the pressurizing operation unit 44 while the discharge ports 31K and 41K are opened and the air replacement ports 31R and 41R are closed. The content liquid stored in is discharged to the outside from the spouts 31K and 41K via the dip tube 43.

In the container 100 with a measuring device, the measuring body portion 31 and the covering portion 40 (cylinder portion 41, top surface portion 42) are formed of a transparent or translucent material so that the measuring chamber 32 of the measuring cap 30 can be easily seen. Is preferable.

Therefore, the container 100 with a measuring device is used as follows.

The pouring route of the content liquid from the pouring port 25 of the pouring cap 20 to the measuring chamber 32 is closed. As a result, unexpected leakage of the content liquid of the container body 10 is prevented at the pre-use stage including the time of display at the store.

(2) Weighing state (Fig. 2)
The tubular portion 41 of the covering portion 40 is set at the descending side position of the measuring cap 30 with respect to the measuring main body portion 31, and the covering portion 40 is set at the measuring position where the discharge ports 41K and 31K are closed and the air replacement ports 41R and 31R are opened. To.

Further, when the user rotates the measuring cap 30 with respect to the dispensing cap 20, the measuring main body 31 of the measuring cap 30 is screwed upward from the lowering end with respect to the dispensing cap 20, and the metering cap 30 is injected. The outlet opening / closing unit 35 (pouring control means 36) opens a pouring route of the content liquid from the pouring outlet 25 of the pouring cap 20 to the measuring chamber 32.

When the user squeezes and deforms the container body 10, the liquid content of the container body 10 passes through the dip tube 26 and is supplied to the measuring chamber 32 from the pouring outlet 25 of the pouring cap 20. When the liquid in the measuring chamber 32 reaches the height of the upper end level of the spout 25 in the pouring pipe portion 24, the liquid exceeding that height returns to the container body 10 when the container body 10 is restored, and the inside of the measuring chamber 32 A volume of liquid (a fixed amount of liquid such as one day's worth) up to the upper end level of the spout 25 is stored in the container. By squeeze-deforming the container body 10 while observing the scale provided on the peripheral wall of the measuring cap 30 (the measuring body 31 and the cylinder 41 of the covering 40), an appropriate amount smaller than the above quantity is weighed and stored. You can also do it.

The liquid poured into the measuring chamber 32 of the measuring cap 30 by the squeeze deformation of the container body 10 extrudes the air in the upper space of the measuring chamber 32 to the outside from the air replacement ports 31R and 41R. Further, when the squeeze deformation of the container body 10 is restored after weighing, external air is sucked into the container body 10 from the air replacement ports 31R and 41R via the measuring chamber 32 and the spout 25.

(3) Discharge ready state (Fig. 3)
The tubular portion 41 of the covering portion 40 is pulled up to a position on the ascending side with respect to the measuring main body portion 31, and the covering portion 40 is set to a pouring position in which the discharge ports 41K and 31K are opened and the air replacement ports 41R and 31R are closed.

Further, the measuring main body 31 of the measuring cap 30 is screwed to the descending end with respect to the pouring cap 20, and the pouring outlet opening / closing part 35 (pouring control means 36) of the measuring cap 30 measures from the pouring port 25 of the pouring cap 20. The pouring route of the content liquid to the chamber 32 is closed.

(4) Discharge state (Fig. 4)
With the discharge preparation of (3) described above, the pressurizing operation portion 44 formed of the top surface portion 42 of the covering portion 40 is pressed and deformed to pressurize the measuring chamber 32. As a result, the content liquid stored in the measuring chamber 32 is discharged to the outside from the discharge ports 31K and 41K via the dip tube 43. If the entire amount of the fixed amount of liquid stored in the measuring chamber 32 cannot be discharged by one pressurization operation, the pressurization operation is repeated as many times as necessary to discharge the entire amount.

According to this embodiment, the following effects are exhibited.
(a) Discharge ports 31K and 41K in which the measuring cap 30 allows the content liquid stored in the measuring chamber 32 to be discharged to the outside, and air replacement ports 31R and 41R that enable the upper space of the measuring chamber 32 to communicate with the outside. Are provided separately from each other, and at the time of the next weighing performed following the previous discharge operation, the container body 10 is pressurized by the squeeze deformation and poured from the pouring port 25 of the pouring cap 20 into the measuring chamber 32 of the measuring cap 30. When the content liquid extrudes the air inside the measuring chamber 32, the discharge ports 31K and 41K are closed and the air replacement ports 31R and 41R are opened. Therefore, at the time of the next weighing, all of the air extruded by the content liquid injected into the measuring chamber 32 as described above does not pass through the discharge ports 31K and 41K, but passes through the air replacement ports 31R and 41R to the outside. It will be discharged. As a result, the residual liquid adhering to the discharge ports 31K and 41K at the time of the previous discharge does not seem to be blown out by the above-mentioned flow of air extruded to the outside, and drips from the discharge ports 31K and 41K. Can be reliably suppressed.

(b) The measuring cap 30 includes a covering portion 40 that covers the upper space of the measuring chamber 32 formed by the measuring main body portion 31. Therefore, even if the content liquid is vigorously poured out from the spout 25 of the container body 10 that has been rapidly squeezed and deformed when the content liquid is weighed, the content liquid is surely prevented from scattering to the outside due to the presence of the covering portion 40. Will be done.

The discharge positions are set to open the discharge ports 31K and 41K and close the air replacement ports 31R and 41R. Therefore, it is possible to prevent the drops from dripping from the discharge ports 31K and 41K at the time of the next weighing according to the above (a) by a simple configuration.

(d) The pouring of the content liquid from the pouring port 25 of the pouring cap 20 to the measuring chamber 32 of the measuring cap 30 is stopped by the pouring control means 36, and the discharge ports 31K and 41K are opened, and the air replacement port 31R By pressurizing the measuring chamber 32 of the measuring cap 30 by the pressurizing operation unit 44 while the 41R is closed, the internal pressure of the measuring chamber 32 can be increased without escaping. Then, the high pressure generated in this way pressurizes the content liquid stored in the measuring chamber 32 and can smoothly discharge the content liquid from the discharge ports 31K and 41K to the outside, and it is necessary to tilt the container greatly when discharging the content liquid. There is no.

(e) The covering portion 40 that covers the upper space of the measuring cap 30 and can be elastically deformed is referred to as the pressurizing operation portion 44. Therefore, with a simple configuration, the pressurizing operation unit 44 described in (d) above can be provided.

(f) The measuring cap 30 includes a spout opening / closing portion 35 that opens and closes a pouring path of the content liquid from the pouring port 25 of the pouring cap 20 to the measuring chamber 32 of the measuring cap 30. Then, the measuring cap 30 is made movable with respect to the pouring cap 20, and the pouring outlet opening / closing unit 35 switches between the pouring position for opening the pouring path and the pouring stop position for closing the pouring path. Will be done. Therefore, with a simple configuration, the above-mentioned pouring control means 36 (d) can be provided.

In the present invention, the measuring cap separately provides a discharge port for discharging the content liquid stored in the measuring chamber to the outside and an air replacement port for allowing the upper space of the measuring chamber to communicate with the outside. As long as it is sufficient, the discharge port having a large discharge resistance does not necessarily close as described in (a) above when the content liquid discharged from the injection port of the injection cap is stored in the measurement chamber of the measurement cap. It may be provided with. That is, at the time of the next weighing performed following the previous discharge operation, the content liquid that is pressurized by the squeeze deformation of the container body and is poured out from the injection port of the dispensing cap to the measuring chamber of the measuring cap removes the air inside the measuring chamber. When extruding from the air replacement port, the passage resistance of the discharge port can be set large. According to this, most of the air extruded by the content liquid injected into the measuring chamber as described above is discharged to the outside through the air replacement port without passing through the discharge port. Therefore, it is possible to prevent the residual liquid adhering to the discharge port at the time of the previous discharge from being blown out by the flow of air extruded to the outside through the discharge port and dripping from the discharge port.

According to the present invention, it is possible to prevent the residual liquid adhering to the discharge port of the measuring cap at the time of the previous discharge from dripping from the discharge port at the time of the next weighing performed by squeeze-deforming the container body. Can be done.

Further, according to the present invention, it is possible to reliably prevent the content liquid that is pressurized by the squeeze deformation of the container body and is poured out from the pouring outlet of the pouring cap to the outside.

Further, according to the present invention, it is possible to discharge the content liquid stored in the measuring chamber of the measuring cap without tilting the container significantly.
