Description

  The present invention relates to a dispensing nozzle with a measuring device that directly pours out the contents contained in a container main body, or accurately measures and dispenses a necessary fixed amount.

  As a prior art for pouring out a certain amount of contents such as liquid detergent and powder detergent, for example, techniques relating to a quantitative stopper as shown in Patent Document 1, Patent Document 2, and Patent Document 3 below have been proposed.

  FIG. 13 is a cross-sectional view showing a quantitative stopper as a conventional example. All of these prior arts have the same basic structure, and as shown in FIG. 13, a fixed stopper 100 is attached to a container 110 filled with contents. The metering plug 100 includes a cup-shaped main body 103 having an inlet 101 and an outlet 102. The cup-shaped main body 103 has a preliminary chamber 105 connected to the inflow port 101 by a partition member 104 and a measuring chamber 106 connected to the discharge port 102 and the preliminary chamber 105.

  When the container 110 is tilted, the contents in the container 110 enter the preliminary chamber 105 in the cup-shaped main body 103 from the inlet 101. At the same time, a certain amount of contents held in the measuring chamber 106 are discharged from the discharge port 102. Thereafter, when the container 110 is returned to the original posture, the contents in the preliminary chamber 105 are transferred to the measuring chamber 106, but excess contents exceeding the volume of the measuring chamber 106 are returned from the inlet 101 into the container 110.

  However, the conventional prior art has a package configuration in which the metering plug 100 is integrally provided in the container 110 in advance, and the metering plug 100 is discarded together with the container 110 after the contents are used up. There is a problem that the effective utilization of resources is low.

  In the conventional prior art described above, since it is necessary to provide the metering plug 100 inside the container 110, the internal volume of the contents that can be accommodated in the container 110 is reduced accordingly, or the same internal volume is reduced. In order to ensure, there is a problem that it is necessary to enlarge the outer shape of the container 110.

  Further, the conventional prior art has a configuration in which only a certain amount of contents can be always poured out. For this reason, for example, when the content is a liquid detergent or a powder detergent, the washing machine tub has a constant volume, so that it is preferable that the amount of detergent can be adjusted according to the amount of laundry, The conventional prior art has a problem that it is difficult to adjust and dispense an amount of detergent according to taste.

  Furthermore, according to the conventional prior art described above, depending on the inclination angle of the container 110, the contents that have entered the spare chamber 105 in the cup-shaped main body 103 from the inflow port 101 overflow, and pass over the partition member 104 as it is. 102 may be discharged. As a result, there is a problem that the volume of the contents to be dispensed in a quantitative manner varies depending on the inclination angle of the container 110, that is, there is a problem that the accuracy of the quantitative dispensing is likely to be lowered.

  In order to solve the problems in the prior art described above, the present invention can be freely attached to and detached from the mouth tube portion of a commercially available container body and can prevent a decrease in the internal volume of the container body, and the contents can be used as they are. The challenge is to create a dispensing nozzle with a meter that allows direct dispensing and quantitative dispensing to dispense a certain amount of content with high accuracy.

  To attach the dispensing nozzle 10A to the container body 1, first, the screw cap is removed from the container body 1 to expose the dispensing portion 3a. And while making the extraction part 3a insert in the insertion part 12e between the outer wall part 12a which comprises the connection part 12, and the 2nd inner ring 12b, the thread groove 12f by the side of the extraction nozzle 10A is made into the extraction part 3a. The screwing nozzle 10A is assembled to the lid main body 3A on the container main body 1 side by screwing (screw coupling) into the screw groove 3b. At this time, since the second inner ring 12b on the side of the pouring nozzle 10A is in close contact with the inner wall of the pouring portion 3a, it is possible to reliably prevent the leakage of the contents 40 between the pouring portion 3a and the connecting portion 12. It becomes possible.

  The dispensing nozzle 10A can be attached to the container body 1 in a closed state in which the lid 20A is fitted on the tip of the outer nozzle 15 or in an opened state with the lid 20A removed. You can also.

  Next, the dispensing of the container body to which the dispensing nozzle is connected will be described.

  In the following description, the case where the direction of the tip portion 31A having an inclined cross section is set to the minimum dispensing mode will be described.

Figure 3 shows an erecting posture as sectional view, FIG. 4 is an initial operation of quantitative dispense in real施例the container body and the pouring nozzle shown a direct pouring of using pouring nozzle of the real施例sectional view of the dispensing nozzle and the container body and the minimum dispense modes, 5 and dispensing nozzles and erecting the container body showing a posture and minimum dispense mode as medium-term operation of quantitative dispense in real施例sectional view, FIG. 6 is a sectional view of the pouring nozzle was quantified dispense container body and the minimum dispense mode indicating inclined position as end operations in the real施例, 7 out quantitative Note in real施例It is sectional drawing of the container main body which shows the erect attitude | position as medium-term operation, and the extraction | pouring nozzle set to the maximum extraction | pouring mode.

(1) Direct pouring operation In the state shown in FIG. 2A in which the pouring nozzle 10A is assembled to the container body 1 and the container body 1 is in the upright posture, the lid body 20A is removed and the lid is opened. Subsequently, the container body 1 is tilted to the inclined posture shown in FIG. Then, the contents 40 accommodated in the container main body 1 are transferred into the mouth tube portion 2 and the extraction portion 3a on the container main body 1 side, the second inner ring 12b on the extraction nozzle 10A side, and the flow path in the inner nozzle 14. 16 and the adjustment inner nozzle 31 on the adjustment nozzle 30 side, the adjustment inner nozzle 31 reaches the non-adjustment nozzle 32 from the tip end portion 31A having an inclined cross section. Therefore, by adjusting the inclination angle of the container main body 1, an amount of the content 40 according to preference can be poured out through the dispensing end 32 </ b> A that is the tip of the non-adjustment nozzle 32 (direct dispensing). .

(2) Quantitative pouring operation From the state shown in FIG. 2A in which the pouring nozzle 10A is closed and the container body 1 is in the upright posture, the container body 1 is changed to an inverted posture or an inclined posture as shown in FIG. To do. As a result, the contents 40 accommodated in the container body 1 move to the dispensing end 32A side of the tip of the non-adjustment nozzle 32 through the flow path 16 and the adjustment inner nozzle 31 in the inner nozzle 14, and enter the spare chamber 18. Stored (initial operation).

  Next, as shown in FIG. 5, when the container main body 1 is returned to the original upright posture, a part of the contents 40 stored in the preliminary chamber 18 moves to the measuring chamber 17, and the measuring chamber 17 is moved. Fulfill. At the same time, the excessive contents 40 exceeding the volume of the measuring chamber 17 enter the adjustment inner nozzle 31 from the shortest portion of the length dimension located on the inclined side of the tip end portion 31A of the adjustment inner nozzle 31 having an inclined cross section. Since it flows in and returns to the inside of the container main body 1 through the flow path 16, a minimum amount of the contents 40 can be left in the measuring chamber 17 (medium-term operation).

  Then, the lid 20 is set to the open state, and then the posture of the container body 1 is changed to the inclined posture shown in FIG. Thereby, only the minimum content 40 stored in the measurement chamber 17 can be poured out from the dispensing end 32A (final operation).

  In addition, by adjusting the inclination posture of the container main body 1, the bottom wall 12 c of the connection portion 12 constituting the measuring chamber 17 can block the pouring of the contents 40 accommodated in the container main body 1. .

  When the adjustment nozzle 30 is rotated around the center line OO of the nozzle body 11 from the state shown in FIG. 2A, which is the minimum dispensing mode, and the direction of the tip portion 31A having an inclined cross section is changed by 180 degrees, the adjustment inner nozzle 31 is moved. Of the peripheral walls to be formed, the peripheral wall portion having the longest length dimension can be set to the maximum dispensing mode in which the nozzle body 11 is in the inclined direction (see FIG. 7).

  Even in the maximum dispensing mode, the same operation as the above (1) can be performed to directly dispense the content 40 as it is. Further, the contents 40 can be quantitatively dispensed by performing a series of operations (initial operation, medium-term operation and final operation) similar to the above (2) in the maximum dispensing mode. In particular, as shown in FIG. 7, in the mid-term operation, the peripheral wall portion having the longest length among the peripheral walls forming the adjustment inner nozzle 31 coincides with the inclination direction of the nozzle body 11. The maximum volume can be maximized. Therefore, since the maximum amount of the content 40 can remain in the measuring chamber 17, the maximum amount of the content 40 can be quantitatively poured out.

  The volume that can be stored in the measuring chamber 17 is the same as the volume in the minimum dispensing mode by rotating the direction (rotation angle) of the tip portion 31A having an inclined cross section around the center line OO of the adjustment nozzle 30. It is possible to arbitrarily adjust the volume in the dispensing mode. For this reason, by performing the series of operations (2) with the direction of the tip portion 31A having an inclined cross-section set to a preferred rotation angle, a desired amount of dispensing (between the minimum amount and the maximum amount). It is possible to dispense a fixed amount).

In the real施例, thereby forming irregularities for rotation angle setting arranged at regular intervals in the circumferential direction within the concave latching portions 15b, 1 or more to be hooked lightly this uneven as Kaketometotsu portion 35a It is preferable to make it the structure provided with this convex part. In this configuration, the rotation angle of the adjustment nozzle 30 can be fixed in a state adjusted to a desired angle, so that a fixed amount of content 40 is dispensed for each series of operations in (2) above. It can be easily realized.

It will now be described reference example of pouring nozzle with weighing device.

With this operation, the lower end of the adjustment inner nozzle 31 is connected to the tip of the inner nozzle 14, and the lower end of the adjustment outer nozzle 32 is connected to the tip of the outer nozzle 15.

  The adjustment nozzle 30 is slidable along the center line OO as much as the length of the engaging portion 35 is long. The state shown in FIG. 9 in which the adjustment nozzle 30 is slid to the position closest to the connecting portion 12 is the minimum pouring mode, and the state shown in FIG. 10 slid to the position farthest from the connecting portion 12 is the maximum pouring. Mode.

  On the other hand, in the minimum dispensing mode shown in FIG. 9, a dimensional difference L between the tip end portion 31B of the non-adjustment nozzle 32 on the adjustment nozzle 30 side and the opening end 14A of the tip of the inner nozzle 14 on the nozzle body 11 side. And the volume of the measuring chamber 17 is in a minimum state. On the other hand, the maximum dispensing mode shown in FIG. 10 has a large dimensional difference L, and the capacity adjusting portion 34 is interposed at the tip of the opening end 14A. Therefore, the substantial volume of the measuring chamber 17 is in the maximum state.

  As shown in FIG. 10, in the maximum dispensing mode, the adjustment nozzle 30 reaches the position of the movement end where the amount of movement toward the tip side is maximum. At this position, the first latching protrusion 15c and the Since the movement of the adjustment nozzle 30 is restricted due to contact with the second latching convex portion 35 a, the adjustment nozzle 30 does not easily fall off from the opening end 11 </ b> A of the nozzle body 11.

  Furthermore, it is possible to adjust the measuring chamber 17 to an arbitrary volume by sliding the adjustment nozzle 30 between the minimum and maximum dispensing modes along the center line OO (optional note). Out mode).

(1) Direct dispensing operation The direct dispensing operation may be in any of the above-described minimum dispensing mode, maximum dispensing mode, and optional dispensing mode, and is the same as the above (1) direct dispensing operation By performing the operation and appropriately adjusting the tilt angle of the container body 1, it is possible to pour out an amount of the content 40 according to preference through the pour-out end 32 </ b> A that is the tip of the non-adjustment nozzle 32. is there.

(2) Quantitative dispensing operation The quantitative dispensing operation can be performed in any of the minimum dispensing mode, the maximum dispensing mode, and the arbitrary dispensing mode.

The pouring nozzle 10B from the state shown with the lid closed and and the container body 1 to a minimum dispense mode and erect posture (see FIG. 9) and the maximum dispense mode (see FIG. 10), the actual施例similarly container body 1 is set in an inverted posture or an inclined posture, and the contents 40 stored in the container main body 1 are stored in the preliminary chamber 18 (initial operation).

  Next, when the container main body 1 is returned to the original upright posture, a part of the contents 40 stored in the preliminary chamber 18 moves to the measuring chamber 17 and fills the measuring chamber 17. At the same time, the excessive contents 40 exceeding the volume of the measuring chamber 17 flow into the adjustment inner nozzle 31 from the tip 31B having a flat cross section of the adjustment inner nozzle 31, and enter the container body 1 through the flow path 16. Therefore, the contents 40 can remain in the measuring chamber 17 (medium-term operation).

  Here, in the minimum dispensing mode, the minimum amount of contents 40 can be stored in the weighing chamber 17 as shown in FIG. 11, and in the maximum dispensing mode, as shown in FIG. In addition, the maximum amount of contents 40 can be stored in the weighing chamber 17. Of course, in the case of the arbitrary dispensing mode, it is possible to leave the content 40 corresponding to the amount in the measuring chamber 17.

Then, set the cover unit 20B in the open lid state, followed by the actual施例Similarly, by the orientation of the container body 1 in an inclined position, only the contents 40 that is stored in the metering chamber 17, Note A fixed amount can be poured out from the end 32A (final operation).

  In addition, by adjusting the inclination posture of the container main body 1, the bottom wall 12 c of the connection portion 12 constituting the measuring chamber 17 can block the pouring of the contents 40 accommodated in the container main body 1. .

In the reference example , the center line OO is formed on the inner surface of the engaging portion 35 facing the first latching convex portion 15c or on the outer surface of the outer nozzle 15 facing the second latching convex portion 35a. It is preferable to form a concavity and convexity for setting the latching position that are arranged at regular intervals in the direction along. In this configuration, when the adjustment nozzle 30 slides, the first latching convex portion 15c or the second latching convex portion 35a is lightly latched by the unevenness, and the adjustment nozzle 30 is moved to the center line OO. Since it can be fixed in a state adjusted to a desired position along the line, when performing the series of operations (2) above, it is easy to realize quantitative dispensing, in which a constant amount of content 40 is always poured out. Can do.

  As mentioned above, although the structure of this invention and its effect were demonstrated along the Example, embodiment of this invention is not limited to the said Example.

  For example, in the above-described embodiment, the structure in which the dispensing nozzles 10A and 10B are attached to the dispensing portion 3a of the lid body 3A of the container-side lid 3 has been described, but the present invention is not limited to the above-described embodiment. Instead, it may be configured to be directly attached to the mouth tube portion 2 of the container body 1.

Above you施例, the concave latching portions 15b formed on the outer nozzle 15 of the nozzle body 11 side, has been described with reference to the case of forming the engaging protrusion 35a to the engagement portion 35 of the adjusting nozzle 30 side, The present invention is not limited to the above-described embodiment, and a latching convex portion may be formed on the nozzle body 11 side and a latching concave portion may be formed on the adjustment nozzle 30 side.

  In addition, the connection portion 12 has been described with a configuration in which the connection portion 12 is screwed to the mouth tube portion 2 by a screw mechanism. However, the present invention is not limited to the above-described embodiment, and the connection portion 12 in the mouth tube portion 2 and the lid main body 3A. Similarly to the configuration, the connecting portion 12 of the dispensing nozzle 10 may be assembled by undercut coupling to the mouth tube portion 2 of the container body 1.

  Moreover, in the said Example, although the resin material which forms extraction nozzle 10A and 10B is not mentioned in particular, the structure which forms at least the nozzle main body 11 and the adjustment nozzle 30 using a transparent or translucent resin material is preferable. In this configuration, since the state inside the nozzle body 11 can be visually confirmed from the outside, it is easy to adjust the inclination angle of the container body during direct dispensing, or each operation (initial operation) during quantitative dispensing. In addition, since it is possible to easily check the status of the middle-term operation and final-term operation), the contents can be reliably poured out.

  The dispensing nozzle of the present invention achieves selective dispensing between direct dispensing and quantitative dispensing while mounted on a commercially available container body, and further pursues adjustment of the dispensing amount during quantitative dispensing. Application development in the field of dispensing nozzles can be achieved in a wide area.
