DETAILED DESCRIPTION OF THE INVENTION
1 is a schematic diagram showing a small metering state of a variable metering stopper, FIG. 2 is a schematic diagram showing a large metering state of the variable metering stopper, FIG. 3 is a schematic diagram showing a usage state of the variable metering stopper, and FIG. FIG. 5 is a schematic diagram showing a tapered cylinder, and FIG. 6 is a schematic diagram showing a measuring rod.
[0016]
As shown in FIGS. 1 and 4, the variable metering stopper 10 is provided in the opening 1A of the container 1 containing powder such as detergent and granular contents, and the discharge amount of the contents once is determined, The quantitative value is variable.
[0017]
The variable metering stopper 10 includes a cover cap 11, a tapered cylinder 21, and a measuring rod 31.
[0018]
As shown in FIG. 4, the cover cap 11 is made of a resin molded body, and includes an exterior cylinder portion 11A that is screwed or fitted around the opening 1A of the container 1 and a top surface portion 11B that covers the opening 1A. The cover cap 11 includes a slide hole 12 for the measuring rod 31 in the center of the top surface portion 11B, and a discharge port 13 for contents on the front edge side of the top surface portion 11B.
[0019]
At this time, the cover cap 11 has an opening / closing lid 15 that is integrally coupled (integrated molding) around the discharge port 13 via a hinge 14. The opening / closing lid 15 includes a concave locking portion 17 that can be engaged with and disengaged from the protruding locking portion 16 provided on the outer edge of the top surface portion 11 </ b> B of the cover cap 11, so that the closed state of the opening / closing lid 15 can be maintained. The opening / closing lid 15 is opened by an opening operation applied to the protruding operation portion 18 at the tip.
[0020]
As shown in FIG. 5, the tapered cylinder 21 is made of a resin molded body, and includes an inner cylinder part 21 </ b> A fitted to the inner peripheral part of the opening 1 </ b> A of the container 1 covered with the cover cap 11, and the inner cylinder part 21 </ b> A. A flange portion 21B provided at the upper end and held by the cover cap 11, and an upper small-diameter communication port 22 is erected from the lower end (inner wall side of the opening portion 11A) of the interior cylindrical portion 21A to the center side of the opening portion 11A. The taper cylinder part 21C is provided.
[0021]
As shown in FIG. 6, the measuring rod 31 is made of a resin molded body, and is located outside the cover cap 11 at the center of the top surface portion 11 </ b> B of the cover cap 11 in the slide hole 12 facing the communication port 22 of the tapered cylinder 21. Is a bottomed cylindrical body that is slidably inserted from above and opens around the communication port 22 of the tapered cylinder 21. The measuring rod 31 frictionally contacts the slide hole 12 and moves up and down continuously in a stepless manner, or the concave portions 32A to 32C (or convex portions) provided at a plurality of axial positions on the outer surface of the measuring rod 31 are formed in the slide hole 12. It can be moved up and down in multiple stages by sequentially engaging with the provided convex portion 33 (or concave portion). It should be noted that the upper and lower edges of the slide hole 12 provided on the top surface portion 11B of the cover cap 11 are in close contact with the outer peripheral surface of the measuring rod 31 and bite the contents between the measuring rod 31 and the slide hole 12. Sealing portions 19A and 19B are provided for prevention.
[0022]
In other words, the measuring rod 31 is moved up and down with respect to the cover cap 11 by the operating force applied to the operation head portion 31 A located outside the cover cap 11, and is determined by the insertion depth between the measuring tube 31 and the tapered cylinder 21. It is possible to change (one measurement value by the measuring rod 31). At this time, the measurement memory 34 is attached to a plurality of positions in the axial direction of the outer surface of the measurement basket 31, and the current measurement value (quantitative discharge value by the variable metering stopper 10 is determined by the measurement memory 34 matching the top surface portion 11 </ b> B of the cover cap 11. ) Can be seen.
[0023]
Therefore, the variable metering stopper 10 is used as follows.
(1) The container 1 is filled with contents, and the variable metering stopper 10 is attached to the opening 1A of the container 1.
[0024]
(2) Grasping the operation head portion 31A of the measuring rod 31 with fingers, the measuring rod 31 is moved up and down with respect to the cover cap 11, and the amount of the rod determined by the insertion depth between the measuring rod 31 and the tapered cylinder 21 is This time, set to a value commensurate with the desired amount of emissions. If the measuring rod 31 is pulled up with respect to the cover cap 11, the insertion depth of the measuring rod 31 will become shallow and the amount of dredging will increase. This change in the amount of weight is observed by a weighing memory 34 provided on the outer surface of the weighing rod 31.
[0025]
(3) Invert the container 1 (FIG. 3A). As a result, the contents of the container 1 enter the measuring bowl 31 from the communication port 22 of the tapered cylinder 21. As a result, an amount of contents corresponding to the soot amount set in the above (2) flows from the container 1 into the measuring pan 31 and is weighed.
[0026]
(4) Erect the container 1 (Fig. (B)). As a result, the contents weighed by the measuring rod 31 so as to meet the desired amount of discharge at this time according to the above (2) and (3) are approximately (partially returned from the communication port 22 of the tapered cylinder 21 to the container 1). The tapered cylinder 21 is transferred into the tapered cylinder portion 21 </ b> C. This amount of transfer generally matches the desired discharge quantitative amount.
[0027]
(5) Tilt the discharge port 13 of the variable metering stopper 10 downward (FIG. 3C). As a result, the contents of the desired discharge fixed amount transferred into the tapered cylinder 21 by the above (4) are taken out by being swung out from the discharge port 13 or the like.
[0028]
According to the present embodiment, there are the following operations.
(1) The amount of the measuring rod 31 corresponding to the quantitative value discharged from the variable metering tap 10 can be changed by moving the measuring rod 31 up and down with respect to the cover cap 11 from the outside of the cover cap 11. That is, the discharge quantitative value can be measured without removing the cover cap 11.
[0029]
{Circle around (2)} The discharge quantitative value can be finely adjusted continuously or in multiple steps by moving the measuring rod 31 up and down continuously or in multiple steps with respect to the cover cap 11.
[0030]
(3) The change in the discharge quantitative value can be seen by the amount of vertical movement of the measuring rod 31 with respect to the outer surface of the cover cap 11, in other words, the amount of protrusion of the measuring rod on the cap. Therefore, it is easy to grasp the change in the discharge quantitative value as an actual feeling.
[0031]
(4) Since the opening / closing lid 15 for the discharge port 13 of the cover cap 11 is integrally coupled to the cover cap 11, there is no need to provide the opening / closing lid 15 as a separate part from the cover cap 11, and the assembly of the variable metering stopper 10 is improved. The cost can be reduced while improving.
[0033]
【The invention's effect】
As described above, according to the present invention, in the variable metering stopper, the discharge quantitative value can be measured without removing the cover cap, the measurement of the discharge quantitative value can be finely adjusted, and the change in the quantitative value of the discharge quantitative value can be realized. It can be easy to grasp.
