After that, with the cap 89 opened, the fixed discharge container 80 is again inverted (inclined) to discharge the granular material f from the discharge port 88 as shown in FIG. (FIG. 13C shows a state before the cap 89 is opened).

  Another quantitative discharge container is disclosed in Patent Document 2, for example. As shown in FIG. 14, the constant rate discharge container 90 includes a container main body 91 and a cylindrical cap 92 attached to the container main body 91, and the inside of the cap 92 is inclined from the lower inner surface of the cap 92.

  However, in the conventional fixed quantity discharge container 80 disclosed in Patent Document 1, the structure of the fixed quantity discharge part 82 is extremely complicated and the number of parts is large, so that the manufacturing cost is high. Further, when discharging the granular material f, the fixed discharge container 80 is inverted (first operation), the fixed discharge container 80 is upright (second operation), and the fixed discharge container 80 is inverted again (inclined). ) Since the operation (third operation) requires a total of three rotation operations, there is also a problem that it takes a lot of time and effort for the user of the metering discharge container 80.

  On the other hand, in the conventional metering discharge container 90 disclosed in Patent Document 2, since the structure of the cap 92 is simple, the manufacturing cost can be reduced. However, when the contents are discharged, the fixed discharge container 90 is turned upside down (first operation), the fixed discharge container 90 is upright (second operation), and the fixed discharge container 90 is turned over again (inclined). Since a total of three rotation operations (third operation) are required, it takes a lot of trouble to the user of the metering discharge container 90.

  Further, in the conventional metering discharge container 80 disclosed in the Patent Document 1 and the conventional metering discharge container 90 disclosed in the Patent Document 2, when the powder body f has a relatively high hygroscopic property, When the granular material f is discharged to a location where steam is discharged, the granular material f adheres to and adheres to the discharging location, which may cause a problem that the discharge amount becomes extremely small or does not come out. was there.

  As shown in FIGS. 17 and 18, a scraper piece 103 that scrapes off the granular material f is formed on the inner surface of the lid 104, and the granular material is formed on the blocking wall 102 attached to the discharge port 101. Even when the body f adheres, a structure in which the powder body f is scraped by the scraper piece 103 is disclosed (Patent Document 3). 17 is a bottom view of the lid 104, and FIG. 18 is a plan sectional view showing a state in which the lid 104 is mounted on a container and the granular material f is scraped off by the scraper piece 103. A support column 105 projecting downward is integrally formed at the center of the lid 104, and four scraper pieces 103 are integrally formed on the outer peripheral surface of the support column 105 at an angular interval. Each scraper piece 103 has an arc shape radially outward from the outer peripheral surface of the support column 105. As shown in FIG. 18, the scraper piece 103 has an arc shape (substantially windmill) that is concave on the downstream side when viewed in the rotation direction when the lid 104 is removed. Shape). In addition, each scraper piece 103 is extended to be gradually inclined downward in the extending direction.

  According to this configuration, when the lid 104 is rotated, the granular material f adhering to the discharge port 101 can be scraped off by the scraper piece 103, so that the discharge amount becomes extremely small or does not come out. It is possible to prevent problems.

  However, since the scraper piece 103 has a complicated shape, it is necessary to provide a special mold or devise a manufacturing process in order to manufacture the scraper piece 103 having such a complicated shape. As a result, the manufacturing cost increases significantly. Further, since it does not prevent the powder f from adhering to the discharge port 101 itself, the powder f attached to the scraper piece 103 scraped off when the lid 104 is opened becomes a large lump. There is a risk of falling outside.

  The present invention solves the above-mentioned problems, can reduce the production cost, and at the same time, can discharge the powder with less trouble, and the quantitative measurement that the powder is difficult to adhere to the discharge location. It aims at providing a spout device and a fixed-quantity discharge container.

In order to solve the above-mentioned problem, the common configuration of the quantitative spout device of the present invention is a quantitative spout device capable of spouting powder particles quantitatively, and one end portion in the axial direction is an outlet And a plurality of shielding plates protruding in an inclined manner from the inner wall surface of the cylindrical portion, and adjacent shielding plates are mutually connected on the inner wall surface of the cylindrical portion. It is arranged in a posture inclined from the opposite surface to the direction opposite to the discharge port, and the position of at least the tip part of the shielding plates is different with respect to the axial direction of the cylindrical wall part. The plate covers the entire width of the opening of the cylindrical part from the connecting part that continues from the inner wall surface of the cylindrical part to the tip part .

  In this configuration, when the fixed amount spout device is attached to the container and the container is tilted in a state in which the powder is accommodated, the powder is placed on the shielding plate arranged in a posture inclined in the direction opposite to the discharge port. After gradually collecting, only a predetermined amount of powder particles are discharged to the outside through the gaps between the shielding plates while overcoming the plurality of shielding plates. After that, the amount of the granular material dammed up by the shielding plate increases, and the weight of the pulverized granular material acts on the granular material near the shielding plate and is pressed, so that a narrow region is obtained. The powder particles are in close contact with each other, and the powder particles are not discharged from the gap between the shielding plates. In this way, a fixed amount of granular material is discharged.

In addition, the quantitative spout device of the present invention is characterized in that at least a part of the shielding plate closest to the discharge port is subjected to roughening such as embossing. In addition, you may comprise so that at least one part of the some shielding board containing the shielding board nearest to an ejection opening may be roughened. Here, it is preferable that the rough surface processing is performed by forming fine uneven portions on at least a part of the shielding plate.

  According to this configuration, since at least a part of the shielding plate is roughened, it is difficult for the granular material to adhere to the shielding plate even when the granular material is discharged to a location where steam is generated. , It becomes difficult to cause a problem that the discharge amount becomes extremely small or does not come out.

  The quantitative spout device of the present invention is characterized in that the connecting portion between the inner wall surface of the cylindrical portion and the shielding plate following the inner wall surface is connected in a curved and recessed shape (arc shape). To do. According to this structure, compared with the case where the connection part of the inner wall surface of the said cylindrical part and the shielding board following this inner wall surface is connected by the linear shape, it is a granular material in the location etc. where steam has come out. Even when the powder is discharged, it becomes difficult for the granular material to adhere to the connecting portion between the inner wall surface of the cylindrical portion and the shielding plate, and it becomes difficult to cause a problem that the discharge amount becomes extremely small or does not come out.

  Here, the tip of each shielding plate is disposed at a position along the diameter direction passing through the axis when viewed in the axial direction of the cylindrical part, or the axial center when viewed in the axial direction of the cylindrical part. Or disposed at a position along a line parallel to the diameter direction passing through. Thereby, it is possible to extract with a relatively stable discharge amount.

  In addition, it is preferable that the shielding plate closest to the discharge port is disposed so as to protrude from the lower portion at the time of discharge on the inner wall surface of the cylindrical portion. With this configuration, a more stable amount can be discharged. .

  Moreover, it is suitable that there are two shielding plates. Furthermore, it is preferable to form the spout device with a spout. Moreover, you may comprise the fixed-quantity discharge container formed by mounting | wearing this container with this fixed-quantity spout apparatus.

  Moreover, when using as a fixed_quantity | quantitative_discharge container, it is suitable if the fixed-quantity spout apparatus is attached to the container main body with the attitude | position which the discharge port provided in the one end part of the cylindrical part turned diagonally upward. That is, in this way, when the discharge port of the cylindrical portion is arranged in an inclined posture, when discharging the granular material as the contents, the quantitative discharge container is further provided on the inclined side. Since there are many cases in which the operation of inclining and discharging is performed, the granular material can be discharged in a more stable amount.

  According to the quantitative spout device of the present invention, it has a cylindrical portion and a plurality of shielding plates, and the adjacent shielding plates are on the opposite side of the discharge port from the mutually facing surfaces of the inner wall surface of the cylindrical portion. It is arranged in a posture inclined to the direction, and at least the position of the tip part of the shielding plates is arranged differently with respect to the axial direction of the cylindrical part, so that a fixed amount of granular material can be discharged, Since it has a very simple structure in which a plurality of shielding plates are disposed inside the cylindrical portion and the number of parts can be reduced, the manufacturing cost can be reduced. In addition, it is possible to discharge a fixed amount of powder and granule by only one tilting operation, and it is possible to discharge the powder and granule with less effort, improving convenience.

  In addition, steaming can be performed by roughening at least a part of the shielding plate closest to the discharge port, or by roughening at least a part of the plurality of shielding plates including the shielding plate closest to the discharge port. Even when powder particles are ejected to the place where they are coming out, it is difficult for the particles to adhere to the shielding plate, and it is difficult to cause a problem that the discharge amount is extremely small or not ejected, improving reliability. To do. In addition, since it is a simple configuration that only roughens at least a part of the shielding plate, there is no need to provide a special mold or devise the manufacturing process, minimizing the increase in manufacturing costs. be able to. In addition, since the powder itself adheres to the shielding plate to a minimum, as in the case of adopting the configuration of Patent Document 3, the powder particles adhered to the scraped scraper pieces are large lump. Thus, it is difficult to cause a problem of falling outside when the lid is opened.

  Further, by connecting the connecting portion between the inner wall surface of the cylindrical portion and the shielding plate following the inner wall surface in a curved and recessed shape (arc shape), the granular material is applied to a location where steam has come out. Even when ejected, the powder and particles are less likely to adhere to the connecting portion between the inner wall surface and the shielding plate, and it is difficult to cause a problem that the ejection amount becomes extremely small or does not come out, thereby improving the reliability. In addition, since it is a simple configuration that only makes the connecting part between the inner wall surface of the cylindrical part and the shielding plate curved and recessed (arc shape), a special mold is provided or the manufacturing process is devised. This eliminates the need to increase the manufacturing cost. Moreover, since it becomes difficult for a granular material to adhere to the connection part of the inner wall face of a cylindrical part, and a shielding board, like the case where the structure of the said patent document 3 is employ | adopted, the granular material adhering to the scraper piece scraped off When the body becomes a large lump and the lid is opened, it is difficult to cause a problem of falling outside.

  Further, the tip of each shielding plate is disposed at a position along the diameter direction passing through the axis when viewed in the axial direction of the cylindrical portion, or the tip of each shielding plate is placed on the axis of the cylindrical portion. By disposing at a position along a line parallel to the diametrical direction passing through the axis when viewed in the center direction, it is possible to extract with a relatively stable discharge amount, and at the same time, the cylindrical portion and the plurality The fixed-quantity spout device can be resin-molded at low cost by, for example, injection molding the shielding plate.

  In addition, it is preferable that the shielding plate closest to the discharge port is disposed so as to protrude from the lower portion on the inner wall surface of the cylindrical portion at the time of discharge. With this configuration, a more stable amount can be discharged. Reliability is improved.

  In addition, when used as a fixed-volume discharge container, when a fixed-quantity spout device is mounted on the container body with the discharge port provided at one end of the cylindrical portion facing obliquely upward, In addition, since the operation of inclining and discharging the metered discharge container to the inclined side is often performed, it is possible to discharge the granular material in a more stable amount, and this also improves the reliability.

  Hereinafter, a fixed-quantity discharge container and a fixed-quantity spout device concerning an embodiment of the invention are explained based on a drawing. In the present embodiment, the container body is a pouch, and a fixed-quantity discharge container in which a spout as a fixed-quantity spout device is attached to the pouch will be described below, but is not limited thereto.

  In FIG. 1, reference numeral 1 denotes a quantitative discharge container according to an embodiment of the present invention, 2 denotes a container main body to which a quantitative spout device 10 made of spout is attached, and the container main body 2 has a granular material as contents. f is accommodated. The container body 2 is configured by a pouch formed by, for example, thermally welding the peripheral portions of two flexible sheets made of synthetic resin or the like. A spout as a fixed quantity spout device 10 is heat-welded to the container body 2 on one side of the upper part while being sandwiched between two flexible sheets.

  As shown in FIG. 1 to FIG. 4 and the like, the quantitative spout device 10 is integrated in a state in which the cylindrical portion 12 is erected on the attachment portion 11 having a plurality of welding ribs 11a welded to the container body 2. It is formed, and the axial center X direction (specifically, a discharge port 21 to be described later) of the cylindrical portion 12 is disposed in an inclined posture facing obliquely upward with respect to the container body 2. A threaded surface 13 to which the cap 5 is screwed is formed on the outer periphery of the distal end portion of the fixed quantity spout device 10. In addition, 6 in FIG. 1 etc. is an opening confirmation ring for making an opening history clear.

  Here, in this embodiment, as shown in FIGS. 2 to 5, the quantitative spout device 10 is a spout formed by integrally forming the mounting portion 11, the cylindrical portion 12, the screw surface 13, and the like. It is comprised from the main body 15 and the some shielding board 16 protruded in the attitude | position which inclines from the inner wall face of the cylindrical part 12 of this spout main body 15. FIG. One end portion (tip portion) in the axial direction of the cylindrical portion 12 is opened as the discharge port 21.

  In the present embodiment, the shielding plate 16 includes a first shielding plate 16A on the upstream side and a second side on the downstream side with respect to the direction in which the granular material f as the contents flows in the cylindrical portion 12. The shielding plate 16B is provided in a state of being integrally formed with the cylindrical portion 12 (that is, a state of being integrally formed with the spout main body 15). And these 1st, 2nd shielding board 16A, 16B is the attitude | position (namely, container main body 2) which inclines in the direction on the opposite side to the discharge outlet 21 from the mutually opposing surface in the inner wall face of the cylindrical part 12. FIG. The posture is such that the granular material f flowing from the inside is dammed up. Further, the position of at least the tip of the shielding plates 16A and 16B is different from the axial direction of the cylindrical portion 12, and a gap is formed between the tips of the shielding plates 16A and 16B. . In this embodiment, the entire first shielding plate 16A including the tip is disposed on the upstream side of the second shielding plate 16B. In this embodiment, the shielding plates 16A and 16B are also integrally formed with the spout main body 15. However, a separate cylindrical wall portion to be attached to the cylindrical portion 12 of the spout main body 15 is provided. The shielding plates 16A and 16B may be integrally formed on the cylindrical wall portion.

  Moreover, in this embodiment, the front-end | tip part of each shielding board 16A, 16B is divided into 2 by the plane along the axial center X of the cylindrical part 12, and the front-end | tip parts of each shielding board 16A, 16B are discharge ports. 21 is disposed at a position substantially coincident with the axial direction of the shaft 21. As shown in FIG. 5 and the like, in this embodiment, each shielding plate 16A, 16B is semicircular when viewed in the axial direction of the discharge port 21, and the tip of each shielding plate 16A, 16B When viewed in the direction of the center X, the shield plate 16A is disposed at a position along the diameter direction passing through the axis X, and the tip portions of the shielding plates 16A and 16B substantially coincide. And when discharging the granular material f, as shown to FIG.6 (a)-(c), FIG.7 (a), (b), it is made to incline so that the discharge outlet 21 may become down, The shielding plate 16 (second shielding plate 16B in this embodiment) that is closest to the discharge port 21 is arranged so as to protrude obliquely upward from a location that becomes lower during discharge on the inner wall surface of the cylindrical portion 12. The upstream shielding plate 16 (the first shielding plate 16A in this embodiment) is located on the inner wall surface of the cylindrical portion 12 from a position on the opposite side of the position above this (for example, the left and right opposite sides). It arrange | positions so that it may protrude toward diagonally upward.

  In addition to the above configuration, in this embodiment, the surface portion (so-called upper surface portion) 16Ba facing the discharge port 21 in the second shielding plate 16B closest to the discharge port 21 is roughened (so-called textured processing). Yes. In addition, a connecting portion 22 between the inner wall surface of the cylindrical portion 12 and the second shielding plate 16B (specifically, the surface portion (upper surface portion) 16Ba of the second shielding plate 16B) following the inner wall surface is provided. They are connected in a curved and recessed shape (arc concave shape with a large curvature radius, so-called R shape). The rough surface processing (so-called texture processing) is performed by forming innumerable (many) fine irregularities on the surface of a mold for forming a shielding plate by etching processing, electric discharge processing, blast processing, etc. By molding the resin with a mold, it is manufactured by transferring fine uneven portions, but is not limited thereto. Further, in this embodiment, the back surface portion 16Bb opposite to the front surface portion 16Ba of the second shielding plate 16B and the first shielding plate 16A are not roughened (so-called textured processing). In FIGS. 2 and 4 to 7, etc., the surface portion (so-called upper surface portion) 16Ba of the second shielding plate 16B is roughened, but roughening is performed. In order to make it easier to understand, the fine irregularities of the rough surface processing are emphasized and shown larger.

  In this configuration, when discharging the granular material f, with the cap 5 opened, as shown in FIGS. 6 (a) to 6 (c), FIGS. 7 (a) and 7 (b), obliquely upward. The whole fixed discharge container 1 is inclined so as to be gradually rotated so that the discharge port 21 facing is directed downward from the side. That is, as shown in FIGS. 6A and 6B, first, when the quantitative discharge container 1 starts to be inclined so that the discharge port 21 faces downward, the second shielding plate 16B on the lower side causes powder particles The body f is first dammed and begins to accumulate, and further, some of the granular material f begins to be dammed and accumulated on the upper first shielding plate 16A. At this time, the second shielding plate 16B And the amount of the first shielding plate 16A collected is small, as shown in FIG. 6C, the gap between the distal end portion of the second shielding plate 16B and the distal end portion of the first shielding plate 16A. A predetermined amount of the granular material f is discharged through.

  However, when the quantitative discharge container 1 is further tilted, as shown in FIG. 6C, the granular material f that has accumulated on the second shielding plate 16B and the powder that has accumulated on the second shielding plate 16B. At the time when the particles f increase, the particles f are connected to each other, and the discharge port 21 is inclined so as to face substantially downward, more powder particles are formed on the connected particles f. f is put. Then, the weight of the dammed particles f acts on and presses the powder f near (immediately above) the shielding plates 16A and 16B, so that the particles f are in close contact with each other. In this state, the granular material f is not discharged from the gap between the shielding plates 16A and 16B. In this way, a fixed amount of the granular material f is discharged.

  According to this configuration, while it is possible to roughly discharge a fixed amount of the granular material f, it is extremely simple and the number of parts is reduced by simply arranging the two shielding plates 16 (16A, 16B) inside the cylindrical portion 12. Since it is a structure, the manufacturing cost of the fixed-quantity spout apparatus 10 and by extension, the fixed-quantity discharge container 1 can be made cheaply. In addition, it is possible to discharge a fixed amount of the granular material f by performing the tilting operation only once, and it is possible to discharge the granular material f with very little effort, thereby improving convenience.

  Further, according to the above configuration, since the surface portion (upper surface portion) 16Ba facing the discharge port 21 in the second shielding plate 16B closest to the discharge port 21 is roughened, the granular material f is relatively Even in the case of having a large hygroscopic property, even when the granular material f is discharged to a location where steam is discharged, the granular material f is difficult to adhere to the surface portion (upper surface portion) 16Ba of the second shielding plate 16B. . Further, the connecting portion 22 between the inner wall surface of the cylindrical portion 12 and the second shielding plate 16B (that is, the base end portion of the second shielding plate 16B) following the inner wall surface is connected in a curved and recessed shape. Therefore, in the case where the granular material f has a relatively large hygroscopicity as compared with the case where the connecting portion between the inner wall surface of the cylindrical portion 12 and the second shielding plate 16B is connected in a linear shape. Even when the granular material f is discharged to a location where steam is flowing out, the granular material f is difficult to adhere to the connecting portion 22 between the inner wall surface of the cylindrical portion 12 and the second shielding plate 16B. Thereby, it becomes difficult to produce the malfunction that the discharge amount from the fixed quantity spout apparatus 10 becomes very small, or it does not come out, and reliability improves. Further, the surface portion (upper surface portion) 16Ba of the second shielding plate 16B is roughened, or the connecting portion 22 between the inner wall surface of the cylindrical portion 12 and the second shielding plate 16B is simply curved. Therefore, it is not necessary to provide a special mold or devise the manufacturing process, and the increase in manufacturing cost can be minimized. The connecting portion 22 between the inner wall surface of the cylindrical portion 12 and the second shielding plate 16B is preferably a curved shape having a radius of 2 to 4 mm, for example, but is not limited thereto.

  Further, the rough surface processing of the surface portion (upper surface portion) 16Ba of the second shielding plate 16B and the connecting portion 22 of the second shielding plate 16B are connected in a curved shape, so that the granular material f is present at these locations. Since the adhesion itself can be suppressed to a minimum, the powder particles adhered to the scraped scraper pieces become a large lump when the lid is opened as in the case of adopting the configuration of Patent Document 3. In this case, it is difficult to cause a problem of falling, and this also improves the reliability.

  Moreover, according to the said structure, while being able to discharge the fixed amount of granular material f roughly, it is very simple and only the number of parts by having arrange | positioned two shielding boards 16 (16A, 16B) inside the cylindrical part 12. FIG. Therefore, it is possible to reduce the manufacturing cost of the fixed-quantity spout device 10, and consequently the fixed-quantity discharge container 1. In addition, it is possible to discharge a fixed amount of the granular material f by performing the tilting operation only once, and it is possible to discharge the granular material f with very little effort, thereby improving convenience.

  In addition, according to the above configuration, the distal end portion of each shielding plate 16 (16 </ b> A, 16 </ b> B) is along the axial direction of the cylindrical portion 12, and is substantially aligned with the axial center X when viewed in the axial direction of the cylindrical portion 12. It arrange | positions in the position along the diametrical direction (namely, the front-end | tip parts of several shielding board 16 (16A, 16B) are arrange | positioned in the position substantially corresponded seeing in the axial center direction of the discharge outlet 21. FIG. Therefore, it is possible to dispense with a relatively stable discharge amount while preventing the granular material f from continuing to flow. Further, when the tip portions of the plurality of shielding plates are shaped so as to overlap each other when viewed in the axial direction of the discharge port, the quantitative spout device 10 having the cylindrical portion 12 and the shielding plate 16 is manufactured by injection molding. Although it may become difficult to do, as mentioned above, while the front-end | tip part of each shielding board 16 (16A, 16B) follows the axial center direction of the cylindrical part 12, the axial center direction of the cylindrical part 12 The positions of the plurality of shielding plates 16 (16A, 16B) substantially coincide with each other when viewed in the axial direction of the discharge port 21. By doing so, it becomes possible to perform resin molding at low cost by, for example, injection molding of the quantitative spout device 10, and as a result, the manufacturing cost of the quantitative spout device 10 and the quantitative discharge container 1 can be manufactured at a lower cost. it can.

  Further, as described above, the shielding plate 16 (in this embodiment, the second shielding plate 16B) that is closest to the discharge port 21 protrudes from the lower portion at the time of discharge on the inner wall surface of the cylindrical portion 12. By disposing, the granular material f is stably dammed and can be discharged in a more stable amount. In addition, as described above, in the state where the fixed discharge container 1 is placed on a table or the like, the axial center direction of the cylindrical portion 12 is inclined with respect to the container body 2, and the discharge port of the cylindrical portion 12 When the quantitative spout device 10 is attached to the container main body 2 in a posture in which 21 is directed obliquely upward, the user of the quantitative discharge container 1 is allowed to discharge the granular material f as shown in FIG. As shown in (c) and FIGS. 7 (a) and 7 (b), the entire fixed discharge container 1 is gradually rotated so that the discharge port 21 that faces obliquely upward faces downward from the side. Since there is a high possibility of performing the tilting operation, the granular material f can be discharged in a more stable state, and the reliability is improved.

  In the above embodiment, the case where only the surface portion (so-called upper surface portion) 16Ba of the second shielding plate 16B closest to the discharge port 21 is roughened (so-called textured processing) has been described. However, the present invention is not limited to this, and as shown in FIG. 8, in addition to the surface portion (so-called upper surface portion) 16Ba of the second shielding plate 16B, the back surface portion (so-called lower surface portion) opposite to the surface portion 16Ba. ) 16Bb may also be roughened (so-called textured). Further, the connecting portion 23 between the back surface portion (so-called lower surface portion) opposite to the front surface portion (so-called upper surface portion) 16Ba in the second shielding plate 16B and the inner wall surface of the cylindrical portion 12 is curved and recessed ( You may connect by the curved shape with a large curvature radius, what is called R shape.

  According to this configuration, since the surface portion (upper surface portion) 16Ba and the back surface portion (lower surface portion) 16Bb facing the discharge port 21 in the second shielding plate 16B closest to the discharge port 21 are roughened, Even when the granular material f has a relatively high hygroscopic property, the granular material f is discharged to a location where steam is generated, etc., the surface of the second shielding plate 16B (upper surface portion). It becomes difficult to adhere not only to 16Ba but also to the back surface (lower surface) 16Bb. Further, not only the connecting portion 22 between the inner wall surface of the cylindrical portion 12 and the second shielding plate 16B (that is, the base end portion of the second shielding plate 16B) following the inner wall surface, but also the second shielding plate 16B. The connecting portion 23 between the back surface portion (lower surface portion) 16Bb and the inner wall surface of the cylindrical portion 12 is also connected in a curved and recessed shape (curved shape with a large radius of curvature, so-called R shape). When the granular material f has a relatively large hygroscopicity compared to the case where the connecting portion between the back surface portion (lower surface portion) of the shielding plate 16B and the inner wall surface of the cylindrical portion 12 is connected in a linear shape. Even when the granular material f is discharged to a location where steam is discharged, the granular material f is connected to the inner wall surface of the cylindrical portion 12 and the back surface portion (lower surface portion) 16Bb of the second shielding plate 16B. The part 23 also becomes difficult to adhere. Thereby, the problem that the discharge amount from the quantitative spout device 10 becomes extremely small or does not come out is further less likely to occur, and the reliability is further improved. Further, the back surface portion (lower surface portion) 16Bb of the second shielding plate 16B is roughened, or the connection portion 23 between the back surface portion (lower surface portion) 16Bb of the second shielding plate 16B and the inner wall surface of the cylindrical portion 12. Since it has a simple configuration that only has a curved shape, it is not necessary to provide a special mold or devise the manufacturing process, and the increase in manufacturing cost can be minimized.

  Further, by roughening the back surface portion (lower surface portion) 16Bb of the second shielding plate 16B and connecting the connecting portion 23 with the back surface portion (lower surface portion) 16Bb of the second shielding plate 16B in a curved shape, Since it is minimized that the granular material f adheres to these places, the granular material adhering to the scraper piece scraped off becomes a large lump as in the case of adopting the configuration of Patent Document 3. Thus, it is difficult to cause a problem of dropping to the outside when the lid is opened, and this also improves the reliability.

  In the above embodiment, the surface portion (so-called upper surface portion) 16Ba and the back surface portion (so-called lower surface portion) 16Bb of the second shielding plate 16B closest to the discharge port 21 are roughened (so-called textured processing). Stated. However, the present invention is not limited to this. As shown in FIG. 9, not only the second shielding plate 16B closest to the discharge port 21 but also the first shielding plate 16A far from the discharge port 21 The portion 16Aa may be roughened (see FIG. 9), or the front surface 16Aa and the back surface 16Ab may be roughened (not shown).

According to this configuration, not only the second shielding plate 16B closest to the discharge port 21 but also the first shielding plate 16A, the granular material f is a surface portion (upper surface portion) of the first shielding plate 16A. It becomes difficult to adhere not only to 16Aa but also to the back surface (lower surface) 16Ab . Thereby, the problem that the discharge amount of the granular material f from the fixed quantity spout apparatus 10 becomes extremely small or does not come out more hardly occurs, and the reliability is further improved.

  Moreover, as shown in FIG. 9, the connection part of the 1st shielding board 16A and the inner wall surface of the cylindrical part 12 (the connection part 24 with the surface part of the 1st shielding board 16A, or a connection part with a back surface part). May also be connected in a curved and recessed shape (curved shape with a large curvature radius, so-called R shape). According to this configuration, not only the connection portions 22 and 23 between the second shielding plate 16B closest to the discharge port 21 and the inner wall surface of the cylindrical portion 12, but also the first shielding plate 16A and the cylindrical portion 12 Also about the connection part 24 with an inner wall surface, the granular material f becomes difficult to adhere. Thereby, the problem that the discharge amount from the quantitative spout device 10 becomes extremely small or does not come out is further less likely to occur, and the reliability is further improved.

In the above-described embodiment, the case where the rough surface processing is performed on the entire surface portion (so-called upper surface portion) 16Ba and the back surface portion (so-called lower surface portion) 16Bb is described, but the present invention is not limited to this. Only a part of the so-called upper surface portion 16Ba and the rear surface portion (so-called lower surface portion) 16Bb may be roughened, and even with this configuration, the granular material f adheres compared to the case where no roughening is performed. Therefore, it is possible to reduce the occurrence of a problem that the discharge amount of the granular material f from the quantitative spout device 10 becomes extremely small or does not come out.

  Further, at least a part of the inner wall surface of the cylindrical portion 12 (for example, a portion exposed to the outside with the cap 5 opened facing the discharge port 21) may be roughened. In addition, it is possible to further reduce the adhesion of the granular material f to the inner wall surface of the cylindrical portion 12.

  In the above embodiment, the case where the distance h between the first shielding plate 16A and the second shielding plate 16B is relatively wide (large) is illustrated in FIG. 4 and the like. However, the present invention is not limited to this. Alternatively, the distance h between the first shielding plate 16A and the second shielding plate 16B may be narrow (small). That is, it is preferable that the interval h is relatively wide since the particles f having a large adhesiveness and the particles f having a relatively large weight per volume are likely to be clogged when the interval h is small. Contrary to this, since the powder f having a low adhesiveness or the powder f having a small weight per volume may not stop flowing if the interval h is large, the interval h is relatively narrow. (Small) is preferable. Further, the interval h may be formed small when the amount to be discharged is reduced, and the interval h may be formed large when the amount to be discharged is increased.

  In addition, the inclination angle of the shielding plate 16 (16A, 16B) with respect to the cylindrical portion 12 is formed to be smaller and less sticky with respect to the powder body f that is difficult to flow, such as the powder body f with high stickiness. It is preferable to form a larger size for the easily flowable granular material f such as the granular material f.

  Moreover, in said embodiment, the front-end | tip part of each shielding board 16A, 16B is divided into 2 by the same plane in the plane along the axial center X of the cylindrical part 12, and the axial center direction of the cylindrical part 12 is carried out. Although the case where it is disposed at a position along the diametrical direction passing through the axis X as seen is not limited to this, it is not limited to this, and FIG. 10 (a), (b), FIG. 11 (a), (b) As shown in FIG. 4, the tip portions of the shielding plates 16A and 16B are positioned along a line parallel to the axis X of the cylindrical portion 12, and the axis when viewed in the direction of the axis X of the cylindrical portion 12. You may arrange | position in the position along the line which is parallel with respect to the diameter direction which passes through the center X. FIG. In this case, one shielding plate 16 is made larger and the other shielding plate 16 is made smaller. As shown in FIGS. 10A and 10B, the first shielding plate 16 </ b> A that is farther from the discharge port 21 than the second shielding plate 16 </ b> B that is close to the discharge port 21 is moved from the tubular portion 12 to the inner diameter direction. Although it may be made to protrude greatly or to have a large area when viewed in the axial direction of the cylindrical portion 12, it is not limited to this. Preferably, the second shielding plate 16B adjacent to the discharge port 21 is protruded larger in the inner diameter direction from the cylindrical portion 12 than the first shielding plate 16A separated from the discharge port 21, or the cylindrical portion 12 It may be formed so as to have a large area when viewed in the axial direction. According to this configuration, it is possible to further stabilize the discharge amount once.

  In the above embodiment, the case where the cap 5 is a screw type has been described. However, the present invention is not limited to this, and the cap 31 may be a hinge type instead of using a screw type ( Not shown). In this case, the upstream side first shielding plate 16A is disposed on the side where the hinge is provided in the cylindrical portion, and the downstream side first shielding plate 16A is provided on the side opposite to the side where the hinge is provided. It is preferable that the two shielding plates 16B are disposed, and according to this, the container is inclined to the side opposite to the side on which the hinge is provided, whereby a fixed amount of the granular material f Can be discharged satisfactorily.

  In the above embodiment, the case where two (two) shielding plates 16 (16A, 16B) are provided for the cylindrical portion 12 (cylindrical portion 12) has been described. Instead of this, three (three) or more shielding plates 16 may be provided.

  In the above-described embodiment, the case where the quantitative spout device 10 is a spout and the container main body 2 is a pouch has been described. However, the present invention is not limited to this. For example, a bottle-shaped container or the like is used as the container main body. The fixed-quantity spout device may be any device provided with a plurality of shielding plates on various cylindrical wall portions such as a cylindrical shape and a rectangular tube shape.
