Description

  The present invention relates to a container with a weighing device.

  There exists a thing of patent document 1 as a container with a measuring device which enabled it to measure and discharge the content liquid of a container main body only for the usage-amount of a day, for example.

  This container with a weighing device is attached to a container body formed of a flexible material such as a plastic bottle, and the container body, and the liquid in the container body is pressurized and poured out by squeeze deformation of the container body. A pouring cap provided with an outlet and a measuring cap provided in the pouring cap and provided with a measuring chamber in which the content liquid poured out from the pouring outlet of the pouring cap is stored. A predetermined amount of content liquid stored in the measuring chamber of the measuring cap is poured out from an opening provided in the upper portion of the measuring chamber by tilting the container.

  Here, the opening provided in the upper portion of the measuring chamber provided in the measuring cap not only functions as a discharge port that allows the content liquid stored in the measuring chamber to be discharged to the outside, but also opens the upper space of the measuring chamber. It also functions as an air replacement port communicating with the outside. That is, at the time of measurement, the content liquid in the container body pressurized by the squeeze deformation of the container body and poured out from the spout of the dispensing cap into the measuring chamber of the measuring cap uses the air inside the measuring chamber as the air replacement port. It extrudes from the said opening part of the outside. When restoring the squeeze deformation of the container body after weighing, external air is sucked into the container body from the opening serving as an air replacement port via the weighing chamber of the measuring cap and the spout of the dispensing cap.

The discharge port 31K and the air replacement port 31R always face the measuring chamber 32, and the discharge port 41K and the air replacement port 41R always face the external space.

  It should be noted that the metering cap 30 is metered so as not to generate as much opportunity as possible for the content liquid supplied and stored in the metering chamber 32 from the spout 25 of the dispensing cap 20 to adhere to the air replacement ports 31R and 41R. The positions of the air replacement ports 31 </ b> R and 41 </ b> R provided in the main body portion 31 and the cylinder portion 41 are set at positions sufficiently higher than the liquid level of the content liquid supplied to the measuring chamber 32. Further, when the content liquid is discharged from the discharge ports 31K and 41K of the measuring cap 30, the posture of the container 100 tends to be set so that the liquid discharge direction of the discharge port 41K is slightly inclined downward. Since the liquid level becomes higher near the discharge ports 31K and 41K, the air replacement ports 31R and 41R are preferably set to positions opposite to the discharge ports 31K and 41K across the central axis of the container 10.

  And when the cylinder part 41 of the coating | coated part 40 is moved up and down with respect to the measurement main-body part 31, and the cylinder part 41 is set to the above-mentioned downward side position, as for the coating | coated part 40, the discharge port 41K and the discharge port 31K are not. The discharge ports 41K and 31K are connected to each other to close the conduction of the discharge ports 41K and 31K from the measuring chamber 32 to the external space, and the air replacement port 41R is connected to the air replacement port 31R to It is set to a measuring position (FIG. 2) that opens the conduction from the measuring chamber 32 of the air replacement ports 41R and 31R to the external space. Further, when the cylinder portion 41 of the covering portion 40 is set to the above-mentioned ascending position, the covering portion 40 is connected to the discharge port 41K from the measuring chamber 32 of the discharge ports 41K and 31K. A discharge position in which the continuity to the space is opened and the air replacement port 41R is disconnected from the air replacement port 31R and the continuity from the measuring chamber 32 of the air replacement ports 41R and 31R to the external space is closed (see FIG. 3 and FIG. 4).

  That is, in the container 100 with the measuring device, the measuring cap 30 can communicate the discharge ports 31K and 41K that allow the content liquid stored in the measuring chamber 32 to be discharged to the outside and the upper space of the measuring chamber 32 to the outside. Air replacement ports 31R and 41R are provided separately from each other. When the content liquid is poured out from the spout 25 of the spout cap 20 as described above and stored in the measuring chamber 32 of the measuring cap 30, the covering portion 40 is set to the above-described measuring position and the discharge port 31K. , 41K are closed, and the air replacement ports 31R, 41R are opened. On the other hand, when the content liquid stored in the measuring chamber 32 of the measuring cap 30 is discharged, the covering portion 40 is set to the aforementioned discharge position, the discharge ports 31K and 41K are opened, and the air replacement ports 31R and 41R are closed.

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 dispensing control means 36 (the dispensing opening / closing portion 35) stops the dispensing of the content liquid from the dispensing port 25 of the dispensing cap 20 to the measuring chamber 32 of the measuring cap 30, and the covering unit 40 is also described above. The measuring chamber 32 is pressurized by the pressurizing operation unit 44 in a state where the discharge ports 31K and 41K are opened and the air replacement ports 31R and 41R are closed, so that the measuring chamber 32 is pressurized. The content liquid stored in the tank is discharged from the spouts 31K and 41K through the dip tube 43 to the outside.

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

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

The content liquid pouring path from the pouring port 25 of the pouring cap 20 to the measuring chamber 32 is closed. Thereby, the unexpected leakage of the content liquid of the container main body 10 is prevented in the stage before use including the time of store display.

(2) Weighing state (Fig. 2)
The cylinder portion 41 of the covering portion 40 is set to a lower position with respect to the measuring main body portion 31 of the measuring cap 30, and the covering portion 40 is set to a measuring position that closes the discharge ports 41K and 31K and opens the air replacement ports 41R and 31R. The

  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 descending end with respect to the dispensing cap 20, and the measuring cap 30 is poured. The outlet opening / closing part 35 (pouring control means 36) opens the content liquid pouring path from the pouring port 25 of the pouring cap 20 to the measuring chamber 32.

  When the user squeezes and deforms the container body 10, the content liquid in the container body 10 passes through the dip tube 26 and is supplied from the spout 25 of the spout cap 20 to the measuring chamber 32. When the liquid in the measurement chamber 32 reaches the height of the upper end level of the spout 25 in the extraction pipe portion 24, the liquid exceeding the height returns to the container main body 10 when the container main body 10 is restored, Is stored with a volume of liquid up to the upper end level of the spout 25 (quantitative liquid such as one day). The container body 10 is squeezed while looking at the scale provided on the peripheral wall of the measuring cap 30 (the measuring main body 31 and the cylindrical portion 41 of the covering portion 40), and an appropriate amount smaller than the above-mentioned fixed amount is measured and stored. You can also.

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

(3) Discharge preparation state (Fig. 3)
The cylinder part 41 of the covering part 40 is pulled up to a position on the ascending side with respect to the measurement main body part 31, and the covering part 40 is set to the dispensing position that opens the discharge ports 41K and 31K and closes the air replacement ports 41R and 31R.

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

(4) Discharge state (Fig. 4)
In the state where the preparation for discharge described in (3) is made, the pressurizing operation unit 44 including the top surface portion 42 of the covering unit 40 is pressed and deformed to pressurize the measuring chamber 32. Thereby, the content liquid stored in the measurement chamber 32 is discharged from the discharge ports 31 </ b> K and 41 </ b> K to the outside 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 a single pressurizing operation, the pressurizing operation is repeated as many times as necessary to discharge the entire amount.

According to the present embodiment, the following operational effects can be obtained.
(a) Discharge ports 31K and 41K that allow the measurement cap 30 to discharge the content liquid stored in the measurement chamber 32 to the outside, and air replacement ports 31R and 41R that allow the upper space of the measurement chamber 32 to communicate with the outside. Are provided separately from each other, and are pressurized by the squeeze deformation of the container body 10 at the next measurement following the previous discharge operation, and are discharged from the spout 25 of the discharge cap 20 into the measurement chamber 32 of the measurement cap 30. When the content liquid pushed out the air inside the measuring chamber 32, the discharge ports 31K and 41K were closed and the air replacement ports 31R and 41R were opened. Therefore, at the next measurement, all of the air pushed out by the liquid content poured into the measurement 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. Thereby, 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 flow of the air pushed out to the outside, and drops 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 squeezed and deformed rapidly during the measurement of the content liquid, the content liquid is reliably prevented from scattering to the outside due to the presence of the covering portion 40. Is done.

  (c) a measuring position in which the covering portion 40 of the above-described (b) of the measuring cap 30 is movable with respect to the measuring main body 31, closes the discharge ports 31K and 41K, and opens the air replacement ports 31R and 41R; The discharge ports 31K and 41K are opened and switched to the discharge position where the air replacement ports 31R and 41R are closed. Therefore, it is possible to prevent the dripping of the droplets from the discharge ports 31K and 41K during the next measurement according to the above (a) with a simple configuration.

  (d) The dispensing control means 36 stops the dispensing of the content liquid from the dispensing outlet 25 of the dispensing cap 20 to the measuring chamber 32 of the measuring cap 30, and the discharge ports 31K and 41K are opened, and the air replacement port 31R. , 41R is closed, and by pressurizing the measuring chamber 32 of the measuring cap 30 by the pressurizing operation unit 44, the internal pressure of the measuring chamber 32 can be increased without releasing. Then, the content liquid stored in the measuring chamber 32 can be pressurized and discharged smoothly from the discharge ports 31K and 41K to the outside by the high pressure generated in this way, and the container needs to be greatly tilted 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 used as the pressurizing operation portion 44. Therefore, the pressurizing operation unit 44 (d) can be provided with a simple configuration.

  (f) The measuring cap 30 includes a spout opening / closing portion 35 that opens and closes a pouring path for the content liquid from the spout 25 of the spout cap 20 to the measuring chamber 32 of the measuring cap 30. The measuring cap 30 is movable with respect to the pouring cap 20 and is switched between a pouring position where the pouring outlet opening / closing part 35 opens the pouring path and a pouring stop position where the pouring path is closed. Is done. Therefore, the dispensing control means 36 of the above (d) can be provided with a simple configuration.

  In the present invention, the measuring cap is provided with a discharge port that allows the content liquid stored in the measurement chamber to be discharged to the outside and an air replacement port that allows the upper space of the measurement chamber to communicate with the outside. The discharge port with a large discharge resistance is not necessarily closed as described above (a) during the measurement in which the content liquid discharged from the discharge port of the discharge cap is stored in the measurement chamber of the measurement cap. It is good also as a thing provided. That is, at the next measurement performed following the previous discharge operation, the content liquid pressurized by the squeeze deformation of the container body and poured out from the spout of the discharge cap into the measurement chamber of the measurement cap causes the air inside the measurement chamber to When extruding from the air replacement port, the passage resistance of the discharge port can be set large. According to this, much of the air extruded as described above by the content liquid poured into the measuring chamber is discharged outside through the air replacement port without passing through the discharge port. Accordingly, it is possible to suppress the residual liquid adhering to the discharge port during the previous discharge from being blown out by the flow of air pushed out through the discharge port and dropping from the discharge port.

  According to the present invention, it is possible to prevent the residual liquid that has adhered to the discharge port of the measurement cap from dripping from the discharge port during the next measurement performed by squeezing the container body. Can do.
