Description

[Technical field]

[0001] The present disclosure relates to a spray container for granular agents. [Background technology]

[0002] Conventionally, water surface floating self-diffusing granules have been used as herbicides for rice paddies. Various methods have been adopted for spraying granules, including not only manual spraying, but also jumbo granules packaged in water-soluble film, aerial spraying by drones or unmanned helicopters, ground spraying by granulators, spraying by ladle, and water inlet application. Considering the recent decrease in the number of agricultural workers and the aging of the workforce, a simple spraying method that does not require special machinery or labor is preferable in order to reduce the burden on agricultural workers.

[0003] Spraying using a spray container is a method that can easily spray granules without requiring special tools or expensive machinery, and without the user having to wear a carrying container such as a tank or basin on their body. For example, Patent Documents 1 and 2 disclose spray containers for spraying agricultural water surface floating granules. However, the spray containers disclosed in Patent Documents 1 and 2 vary in the amount of spray depending on the user's muscle strength and the way the spray container is swung.

[0004] On the other hand, Patent Documents 3 and 4 disclose discharge containers that discharge a predetermined amount of powder. However, the discharge containers disclosed in Patent Documents 3 and 4 discharge powder from a discharge port by tilting or turning the container upside down, and are not suitable for spreading granules over a wide area.

[0005] [Patent Document 1] Patent Publication No. 2000-300143 [Patent Document 2] Patent Publication No. 2008-245525 [Patent Document 3] Utility model application published No. 1-144385 [Patent Document 4] Utility model application published No. 60-112475 Summary of the Invention [Problem to be solved by the invention]

[0006] The present disclosure provides a spray container suitable for spraying a predetermined amount of granular agent. [Means for solving the problem]

[0007] A first aspect of the present disclosure is a spray container for granules, comprising an injection port configured to inject the granules, a storage chamber configured to store the granules, a metered amount chamber configured to receive a predetermined amount or less of the granules from the storage chamber and to accommodate the received granules, and a discharge section configured to receive the granules stored in the metered amount chamber and to hold the received granules so that they can be sprayed, wherein the spray container is configured such that when the granules are sprayed from the discharge section, the granules do not flow from the storage chamber into the metered amount chamber.

[0008] In the first aspect, a predetermined amount of the granules injected from the injection port is stored in the metering chamber and received by the discharge section, and when this predetermined amount of the granules is sprayed from the discharge section, the granules stored in the storage chamber do not flow into the metering chamber. Therefore, according to the first aspect, it is possible to suppress fluctuations in the amount of spray that depend on the muscle strength of the user who uses the spray container to spray the granules and on the way the spray container is swung, and to spray a predetermined amount of granules.

[0009] A second aspect of the present disclosure is a spraying container according to the first aspect described above, further comprising a first suppression mechanism that suppresses the flow of the granular agent from the storage chamber into the metering chamber when the granular agent is sprayed from the discharge section.

[0010] In the second aspect, when a user uses the spray container to spray granules, the first suppression mechanism provided in the spray container functions to suppress the inflow of the granules from the storage chamber to the metered amount chamber. Therefore, according to the second aspect, the spray container is reliably prevented from spraying an amount of granules exceeding a predetermined amount.

[0011] A third aspect of the present disclosure is a spraying container according to the second aspect above, wherein the storage chamber is connected to the metering chamber along the longitudinal direction of the spraying container from the injection port to the storage chamber, and the discharge portion is located on the opposite side of the metering chamber along the reverse longitudinal direction from the storage chamber to the injection port, and is located forward of the injection port along the reverse longitudinal direction.

[0012] In the third aspect, the metering chamber that stores a predetermined amount or less of granules and the discharge part that receives and disperses the granules from the metering chamber are located on the opposite side of the storage chamber and the inlet along the longitudinal direction of the spraying container. Therefore, according to the third aspect, a sufficient distance is secured between the metering chamber and the discharge part, and the user shakes the spraying container (i.e., rotates the spraying container on a plane including the longitudinal direction), so that sufficient rotational momentum is obtained to spray the granules over a wide area. Then, the user's spraying action gives the granules sufficient rotational momentum, so that it becomes possible to spray small and light granules over a long distance. When the specific gravity and shape are the same, the air resistance acting on the flying granules is generally proportional to the projected area of ​​the granules, so that the magnitude of the air resistance is considered to be proportional to the square of the typical length of the granules (for example, 1 / 2 the sum of the short diameter and the long diameter). On the other hand, the mass of the granules is proportional to the volume of the granules, so that it is considered to be proportional to the cube of the typical length of the granules. Therefore, small granules are more susceptible to air resistance than large granules. Therefore, small granules are generally less likely to reach farther than large granules. According to the third aspect, the user's spraying action can impart sufficient initial velocity to the granules, so that even small granules can be sprayed farther.

[0013] A fourth aspect of the present disclosure is a spraying container according to the third aspect, further comprising a discharge pipe communicating with the metering chamber and the discharge section, the discharge pipe being separated from the storage chamber by a partition plate and extending along the longitudinal direction of the spraying container.

[0014] In the fourth aspect, the discharge pipe, which is partitioned from the storage chamber by the partition plate, extends along the longitudinal direction and communicates between the metered chamber and the discharge section. Therefore, according to the fourth aspect, the internal space of the discharge pipe provides a communication path of sufficient length between the metered chamber and the discharge section, and the granules can be sufficiently spread over a wide area from the spray container shaken by the user. In particular, according to the fourth aspect, it can contribute to providing a sufficient flight distance to small and light granules.

[0015] A fifth aspect of the present disclosure is a spraying container according to the fourth aspect, which is configured such that when the discharge section is positioned vertically below the metering chamber in a plane including the longitudinal direction of the spraying container, the flow of the granules from the storage chamber to the metering chamber is suppressed, while the flow of the granules from the metering chamber to the discharge section is possible.

[0016] In the fifth aspect, when the spraying container is tilted so that the discharge part is located vertically below the metering chamber on a plane including the longitudinal direction of the spraying container, the granules prepared in the metering chamber move to the discharge part, but the granules do not flow from the storage chamber to the metering chamber. Therefore, according to the fifth aspect, the predetermined amount of granules prepared for spraying can be easily moved from the metering chamber to the discharge part by tilting the spraying container.

[0017] A sixth aspect of the present disclosure is a spraying container according to the fifth aspect above, wherein the first suppression mechanism includes an inclined plate that partitions a portion of the outer edge of the storage chamber, extends into the interior of the storage chamber, and is inclined with respect to the longitudinal direction of the spraying container, and the inclined plate is inclined toward the metering chamber in a direction away from the partition plate.

[0018] In the sixth aspect, the first suppression mechanism for suppressing the inflow of granules from the storage chamber to the metering chamber when the granules are sprayed has an inclined plate that defines a part of the outer edge of the storage chamber, extends into the inside of the storage chamber, and is inclined with respect to the longitudinal direction of the spraying container, and this inclined plate is inclined so as to approach the metering chamber as it moves away from the partition plate that separates the discharge pipe and the storage chamber. Because the inclined plate is inclined in this manner, when the spraying container is inclined so that the discharge portion is located vertically above the metering chamber, the inclined plate does not hinder the inflow of granules from the storage chamber to the metering chamber near the partition plate, but rather promotes the inflow. Therefore, according to the sixth aspect, a suitable first suppression mechanism can be provided that suppresses the inflow of granules from the storage chamber to the metering chamber when the granules are sprayed from the discharge portion, while not hindering the preparation of a predetermined amount of granules in the metering chamber by tilting the spraying container.

[0019] A seventh aspect of the present disclosure is the spraying container according to any one of the fourth to sixth aspects, further comprising a gripped part for a user to grip the spraying container when spraying the granular agent.

[0020] In the seventh aspect, a gripped part is provided for a user to grip when spraying the granular agent. Therefore, according to the seventh aspect, a spraying container suitable for user operation when spraying can be provided.

[0021] An eighth aspect of the present disclosure is a spraying container according to the seventh aspect, wherein the gripped portion is configured to have a smaller diameter than a main body portion of the spraying container that contains the storage chamber and a portion of the discharge pipe that extends alongside the storage chamber along the longitudinal direction.

[0022] In the eighth aspect, the gripped portion for the user to grip has a smaller diameter than the main body of the spray container that contains the storage chamber and the portion of the discharge pipe extending alongside the storage chamber. Therefore, according to the eighth aspect, a spray container having a gripped portion that is easy for the user to grip and does not slip can be provided.

[0023] A ninth aspect of the present disclosure is a spraying container according to the eighth aspect, wherein the gripped portion accommodates at least a portion of the metered amount chamber, and the discharge portion is connected to a portion of the discharge pipe protruding from the main body portion along the opposite longitudinal direction.

[0024] In the ninth aspect, the metered chamber and the discharge part are located on opposite sides of the discharge pipe extending along the longitudinal direction, and the gripped part that houses the metered chamber is located on the opposite side of the discharge part, sandwiching the main body part that houses the storage chamber and a part of the discharge pipe. Therefore, when the user grips the gripped part, a sufficient distance is ensured from the user's hand to the discharge part by the discharge pipe extending in the longitudinal direction. Therefore, according to the ninth aspect, the user can obtain sufficient rotational momentum to widely disperse the granules from the discharge part by shaking the spray container (i.e., rotating the spray container on a plane including the longitudinal direction). In particular, according to the ninth aspect, it can contribute to providing a sufficient flight distance to small and light granules.

[0025] A tenth aspect of the present disclosure is a spraying container according to the first to sixth aspects above, further comprising a second suppression mechanism that partitions a portion of the outer edge of the metering chamber and suppresses the flow of more than the predetermined amount of granules from the storage chamber into the metering chamber.

[0026] In the tenth aspect, the second suppression mechanism prevents more than a predetermined amount of granules from flowing from the storage chamber into the metering chamber. Therefore, according to the tenth aspect, it is possible to reliably prevent more than a predetermined amount of granules from being prepared in the metering chamber and finally being sprayed from the discharge part.

[0027] An eleventh aspect of the present disclosure is the spraying container according to any one of the third to sixth aspects, further comprising an adjustment mechanism capable of changing the amount of the granular agent that can be received in the metering chamber.

[0028] In the eleventh aspect, the maximum amount of granules prepared in the metering chamber and finally sprayed from the discharge portion can be changed. Thus, according to the eleventh aspect, the spray amount of the spray container can be changed.

[0029] A twelfth aspect of the present disclosure is a spraying container according to the eleventh aspect, wherein the adjustment mechanism includes a bottom of the metering chamber configured to be movable in a vertical up-down direction when the longitudinal direction is the vertical direction, a rotating shaft connected to the bottom of the metering chamber, extending along the longitudinal direction and configured to be rotated to move the bottom of the metering chamber in the vertical up-down direction, and an operating unit connected to the rotating shaft, operable to rotate the rotating shaft, and configured to be operable by a user from outside the spraying container.

[0030] In the twelfth aspect, the user operates the operating unit from outside, and the bottom of the metered quantity chamber is moved vertically (in both directions along the longitudinal direction) via the rotation of the rotating shaft. When the bottom of the metered quantity chamber is moved, the amount of granules that the metered quantity chamber can accept is changed. Thus, according to the twelfth aspect, a spraying container is provided that allows the spraying amount to be changed by a simple operation.

[0031] A thirteenth aspect of the present disclosure is a spraying container according to the eleventh aspect above, wherein the adjustment mechanism includes a ceiling portion that defines a portion of the outer edge located opposite the bottom of the metering chamber along the vertical direction when the longitudinal direction is the vertical direction, and is configured to be movable in the vertical direction.

[0032] In the thirteenth aspect, the ceiling of the metering chamber is configured to be movable vertically (in both directions along the longitudinal direction). When the ceiling of the metering chamber is moved, the amount of granules that can be received in the metering chamber is changed. Thus, according to the thirteenth aspect, a spraying container capable of changing the amount of spraying is provided.

[0033] A fourteenth aspect of the present disclosure is a spray container according to any one of the first to sixth aspects, wherein the granule is a composition used for agricultural purposes.

[0034] In the above-mentioned fourteenth aspect, the spraying container is used for spraying an agricultural composition formed as a granule. Thus, according to the fourteenth aspect, a spraying container capable of spraying a predetermined amount of agrochemicals, fertilizers, etc. is provided.

[0035] A fifteenth aspect of the present application is a spray container according to the fourteenth aspect, wherein the composition is a water-floating self-diffusing granule.

[0036] In the fifteenth aspect, the granule is a water surface floating self-diffusing granule for agricultural use. Therefore, according to the fifteenth aspect, for example, a predetermined amount of herbicide can be sprayed on a paddy field.

[0037] A sixteenth aspect of the present disclosure is the above-mentioned first to sixth aspects, wherein the minor axis of the granule is 0.8 mm or more and 2.0 mm or less, the major axis of the granule is 0.8 mm or more and 15 mm or less, and the apparent specific gravity of the granule is 0.30 g / m 3 More than 0.60g / cm 3 Below is a spray container.

[0038] In the sixteenth aspect, the granule has a minor axis of 0.8 mm or more and 2.0 mm or less, a major axis of 0.8 mm or more and 15 mm or less, and an apparent specific gravity of the granule is 0.30 g / cm 3 More than 0.60g / cm 3 According to the sixteenth aspect, the size of the sesame seed is about the same as that of a sesame seed, and the specific gravity is 0.5 g / cm3 or less. 3 It is possible to spray a predetermined amount of granular agent such as [Brief description of the drawings]

[0040] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings described below, the same or corresponding components are designated by the same reference numerals, and duplicated descriptions will be omitted.

[0041] FIG. 1 is a perspective view of a spray container 20 according to an embodiment of the present disclosure. As shown in FIG. 1, the spray container 20 includes a cylindrical main body 2 and a gripped part 3 connected to the main body 2 and having a side surface of a substantially one-lobe hyperboloid of revolution. The gripped part 3 is provided for a user to grip the spray container 20. Furthermore, an injection port 1 configured to be able to receive an item into the inside of the spray container 20 is provided on the upper surface of the main body 2. In this embodiment, granules 17 (see FIGS. 4 to 8) described later are injected into the inside of the spray container 20 through the injection port 1. The injection port 1 can be closed by attaching a lid 16 described later. In addition, a hollow discharge pipe 4 protrudes vertically upward from the main body 2, and the tip of the discharge pipe 4 is connected to a discharge container 5. The discharge container 5 is an example of a discharge part of the present disclosure.

[0042] In the drawings described in this disclosure, an XYZ Cartesian coordinate system may be used for convenience of explanation. In each drawing, the Z axis of this coordinate system faces vertically upward. In addition, in FIG. 1, the XY plane is disposed so as to cut the spraying container 20 horizontally. The Z axis can also be said to be the longitudinal direction of the spraying container 20.

[0043] 1 (a surface perpendicular to the Y-axis) is open. With this configuration, the granular agent 17 contained in the discharge container 5 can be sprayed.

[0044] 2 is a cross-sectional view of the spray container 20 along the YZ plane. As shown in FIG. 2, a storage chamber 6 is formed inside the main body 2. The storage chamber 6 is configured to be able to store the granules 17 injected from the injection port 1. Furthermore, inside the main body 2, a discharge pipe 4 extends along the Z-axis direction. Inside the main body 2, the storage chamber 6 and the discharge pipe 4 are partitioned by a partition plate 7.

[0045] A metering chamber 9 communicating with the storage chamber 6 and the discharge pipe 4 is provided vertically below the storage chamber 6. The metering chamber 9 is configured to receive a predetermined amount or less of granules 17 from the storage chamber and to accommodate the received granules 17. Specifically, the metering chamber 9 has a predetermined volume because the vertical upper side is partitioned by the ceiling portion 10 and the vertical lower side is partitioned by the bottom portions 9a and 9b. Focusing particularly on the ceiling portion 10, the ceiling portion 10 partitions a part of the outer edge of the vertical upper side of the metering chamber 9 and suppresses the inflow of granules 17 from the storage chamber 6 to the metering chamber 9 in an amount greater than a predetermined amount (defined by the volume of the metering chamber 9). Note that FIG. 2 shows the metering chamber 9 as spanning the inside of the main body portion 2 and the inside of the gripped portion 3. However, the arrangement of the metering chamber 9 is not limited to this, and the entire metering chamber 9 may be arranged to be accommodated inside the gripped portion 3. The ceiling portion 10 of the metering chamber 9 is an example of the second suppression mechanism of the present disclosure.

[0046] As shown in FIG. 2, a partition member 15 is provided between the storage chamber 6 and the metered amount chamber 9. The partition member 15 is connected to the partition plate 7 and includes an inclined plate 8. The inclined plate 8 partitions a part of the outer edge of the storage chamber 6 on the vertical lower side, extends inside the storage chamber 6, and is inclined with respect to the longitudinal direction of the spraying container 20. Specifically, the inclined plate 8 is inclined toward the metered amount chamber 9 (i.e., toward the vertical lower side) along the direction away from the partition plate 7. In addition, the end of the partition member 15 on the vertical lower side (i.e., the Z-axis negative direction side) constitutes the ceiling portion 10 of the metered amount chamber 9 described above. The partition member 15 is an example of the first suppression mechanism of the present disclosure.

[0047] As shown in Fig. 2, the discharge pipe 4 extends vertically upward (positive direction of the Z axis) from near the bottom 9b of the metering chamber 9 through the inside of the main body 2. The vertically upper end of the discharge pipe 4 is connected to the discharge vessel 5. A stopper 11 is provided at the intersection between the discharge pipe 4 and the discharge vessel 5. When the granules 17 contained in the metering chamber 9 pass through the discharge pipe 4 toward the discharge vessel 5 (see Figs. 5 and 6), the stopper 11 functions to block the flowing granules 17 and store them inside the discharge vessel 5.

[0048] 2, the storage chamber 6 communicates with the metering chamber 9 along the direction from the injection port 1 toward the storage chamber 6 (i.e., the negative direction of the Z axis). On the other hand, the discharge chamber 5 is located on the opposite side of the metering chamber 9 along the direction from the storage chamber 6 toward the injection port 1 (i.e., the positive direction of the Z axis), and is located forward of the injection port 1 along the positive direction of the Z axis (the positive direction of the Z axis).

[0049] As described above, the gripped part 3 is provided so that the user can grip the spray container 20. In particular, when the user uses the spray container 20 to spray the granules 17, it is preferable that the user can stably and easily grip the spray container. As shown in Figs. 1 and 2, the gripped part 3 is configured to have a smaller diameter (outer diameter on the XY plane) than the main body part 2. Furthermore, the gripped part 3 accommodates at least a part of the metered amount chamber 9, while the discharge measure 5 communicates with a part of the discharge pipe 4 protruding from the main body part 2 along the direction from the storage chamber 6 toward the injection port 1 (i.e., the positive direction of the Z axis). In other words, under a configuration in which the metered amount chamber 9 and the discharge measure 5 are located on opposite sides to each other with respect to the discharge pipe 4 extending along the Z axis, the gripped part 3 accommodating the metered amount chamber 9 is located on the opposite side to the discharge measure 5 across the main body part 2 accommodating the storage chamber 6 and a part of the discharge pipe 4.

[0050] Fig. 3 is an enlarged view of the vicinity of the metering chamber 9 in Fig. 2. Note that Fig. 3 and subsequent figures are cross-sectional views taken along the YZ plane of the spraying container 20 shown in Fig. 1, similar to Fig. 2, and therefore the illustration of the XYZ orthogonal coordinate system is omitted.

[0051] As shown in Figs. 2 and 3, the bottoms 9a and 9b of the metered amount chamber 9 are connected to a rotating shaft 14. The rotating shaft 14 extends along the Z-axis direction and is configured to move the bottoms 9a and 9b of the metered amount chamber 9 in the positive and negative directions of the Z-axis by being rotated. The rotating shaft 14 is held by a holding tube 14A and connected to the bottom of the spraying container 20. As shown in Figs. 2 and 3, a dial 13 is provided at the bottom of the spraying container 20. The dial 13 is connected to the rotating shaft 14 and can rotate the rotating shaft 14 by being operated, and is configured to be operable by a user from outside the spraying container 20. When a user operates the dial 13, the bottoms 9a and 9b of the metered amount chamber 9 move in the positive and negative directions of the Z-axis through the rotation of the rotating shaft 14. On the other hand, the volume of the metered amount chamber 9 determines the amount of granules 17 that the metered amount chamber 9 can accept. Therefore, the user can change the amount of granules 17 that the metered amount chamber 9 can accept by operating the dial 13. The combination of the bottoms 9a and 9b of the metering chamber 9, the rotating shaft 14, and the dial 13 is an example of the adjustment mechanism of the present disclosure.

[0052] 3, the partition member 15 may be configured to be movable in the positive and negative directions of the Z axis. For example, the partition member 15 can be configured to be moved by operating an operated part (not shown) provided on the outer surface of the main body 2. As described above, the end of the partition member 15 on the negative Z axis side forms the ceiling part 10 of the fixed-quantity chamber 9. Therefore, the movement of the partition member 15 in the positive and negative Z axis directions changes the volume of the fixed-quantity chamber 9, and further changes the amount of granules 17 that the fixed-quantity chamber 9 can accept. The partition member 15 configured to be movable in the positive and negative Z axis directions is an example of an adjustment mechanism of the present disclosure.

[0053] Fig. 4 is a cross-sectional view along the YZ plane showing the state in which the spray container 20 shown in Fig. 2 is filled with granules 17 through the injection port 1 and the lid 16 is attached to close the injection port 1. For ease of explanation, the detailed configuration of the gripped part 3 (rotating shaft 14, holding cylinder 14A, dial 13) is omitted from Fig. 4 and the subsequent drawings.

[0054] Of the granules 17 filled in the spray container 20, the portion contained in the storage chamber 6 will be referred to as granules 17a, and the portion contained in the metering chamber 9 will be referred to as granules 17b. As shown in Fig. 4, when the granules 17 are filled in the spray container 20, the granules 17 flow into the metering chamber 9 until they reach the acceptable amount determined by the volume of the metering chamber 9, and become granules 17b. When the volume of the granules 17b reaches the acceptable amount of the metering chamber 9, the flow of the granules 17 into the metering chamber 9 stops, and the remaining granules 17 are stored in the storage chamber 6 to form granules 17a.

[0055] 5 is a cross-sectional view along the YZ plane showing the state in which the spraying container 20 shown in FIG. 4 is rotated 90 degrees counterclockwise. In each of the drawings from FIG. 5 onwards, for the sake of convenience, the reference numerals relating to the details of the internal configuration of the spraying container 20 are omitted. The transition from FIG. 4 to FIG. 5 does not involve any substantial change in the position of the granules 17 in the spraying container 20. The granules 17a continue to remain in the storage chamber 6, and the granules 17b continue to remain in the metered amount chamber 9, except for a slight inflow near the end of the discharge pipe 4.

[0056] FIG. 6 is a cross-sectional view along the YZ plane showing the spraying container 20 shown in FIG. 5 tilted counterclockwise. In FIG. 6, in the plane in which the discharge pipe 4 extends along the Z-axis direction or the longitudinal direction of the spraying container 20, the discharge chamber 5 is located vertically below the metered amount chamber 9. Therefore, the granules 17b contained in the metered amount chamber 9 pass through the discharge pipe 4, are blocked by the stopper 11, and are contained in the discharge chamber 5. The granules 17 contained in the discharge chamber 5 are called granules 17c. On the other hand, in this case, since the storage chamber 6 is located vertically below the metered amount chamber 9, there is no inflow of the granules 17 from the storage chamber 6 to the metered amount chamber 9, and the amount of the granules 17a does not change. In other words, the transition from FIG. 5 to FIG. 6 results in all of the granules 17b in the metered amount chamber 9 being moved into the discharge chamber 5 and being contained in the discharge chamber 5 as granules 17c.

[0057] FIG. 7 is a cross-sectional view along the YZ plane showing the spraying container 20 shown in FIG. 5 tilted clockwise. In FIG. 7, in the plane in which the discharge pipe 4 extends along the Z-axis direction or the longitudinal direction of the spraying container 20, the discharge chamber 5 is located vertically above the metering chamber 9. Therefore, no inflow of the granules 17 from the metering chamber 9 to the discharge chamber 5 occurs. On the other hand, since the metering chamber 9 already contains the granules 17b to the limit that it can accept, no inflow of the granules 17 from the storage chamber 6 to the metering chamber 9 occurs, although the storage chamber 6 is located vertically above the metering chamber 9, and the amount of the granules 17a and 17b does not change. In other words, the transition from FIG. 5 to FIG. 7 does not involve any essential positional change of the granules 17 in the spraying container 20.

[0058] On the other hand, the state shown in Fig. 6 can be considered as the starting point of the user's operation of spraying the granules 17 with the spray container 20. Of the granules 17 filled in the spray container 20 in Fig. 4, the granules 17b contained in the metered amount chamber 9 become granules 17c contained in the discharge measure 5 and are waiting to be sprayed. When the user swings out the discharge measure 5 of the spray container 20 shown in Fig. 6 vertically upward (i.e., imparts clockwise rotational momentum to the spray container 20), the granules 17c contained in the discharge measure 5 are sprayed.

[0059] FIG. 8 is a cross-sectional view along the YZ plane, showing the end point of the spraying operation starting from FIG. 6. In FIG. 8, the storage chamber 6 is located vertically above the metering chamber 9. Also, the metering chamber 9 does not contain the granules 17b (all have been moved to the discharge chamber 5 at the time of FIG. 6). Therefore, the granules 17a contained in the storage chamber 6 are about to move to the metering chamber 9. However, in this case, the partition member 15 located between the storage chamber 6 and the metering chamber 9, particularly the inclined plate 8 as a part thereof, suppresses the movement of the granules 17a to the metering chamber 9. As a result, the transition from FIG. 6 to FIG. 8, that is, the spraying operation of the spray container 20 by the user, does not involve the inflow of the granules 17 from the storage chamber 6 to the metering chamber 9.

[0060] In the present disclosure, "no inflow of granules from the storage chamber to the metered chamber" or "suppressing inflow of granules from the storage chamber to the metered chamber" does not mean that inflow of granules from the storage chamber to the metered chamber is completely prevented. When the amount of granules 17a stored in the storage chamber 6, the weight of the granules 17, the length and inclination angle of the inclined plate 8, the magnitude of the rotational moment applied by the user to the spray container 20 during the swing-out operation for spraying, etc. exceed a predetermined threshold value determined as a parameter, the granules 17a stored in the storage chamber 6 may flow into the metered chamber 9 during the spraying operation of the spray container 20 by the user, despite the suppression by the partition member 15 and the inclined plate 8 as a part thereof. In the present disclosure, "no flow of granules from the storage chamber to the metered quantity chamber" or "suppression of flow of granules from the storage chamber to the metered quantity chamber" means that, within the range of the values ​​of the above parameters as understood by a person skilled in the technical field to which the granule spraying container belongs, the flow of granules 17a into the metered quantity chamber 9 beyond the inhibition by the partition member 15 and the inclined plate 8 occurs only to a substantially negligible extent.

[0061] The granules 17 may be, for example, a composition used for agricultural purposes, and in particular may be water-floating self-diffusing granules.

[0062] The granules 17 have a minor axis of 0.8 mm or more and a major axis of 0.8 mm or more and a major axis of 15 mm or less, and an apparent specific gravity of 0.30 g / cm 3 More than 0.60g / cm 3 Preferably, the granule 17 has a minor axis of 1.0 mm or more and 1.5 mm or less, a major axis of 1.0 mm or more and 12 mm or less, and an apparent specific gravity of 0.40 g / cm 3 More than 0.55g / cm 3 It may be the following.

[0063] In addition, it was difficult to sufficiently spread such small and light granules 17 far away using the spraying container according to the conventional technology. Specifically, when spraying using the spraying containers described in Patent Documents 1 and 2, pea-sized granules could reach up to about 6 m, but smaller and lighter granules could only reach up to about 2 to 3 m. This fact is considered to be due to the fact that small and light granules are more strongly affected by air resistance. When the specific gravity and shape are the same, the air resistance acting on the flying granules 17 is generally proportional to the projected area of ​​the granules 17, so the magnitude of the air resistance is considered to be proportional to the square of the representative length of the granules 17 (for example, 1 / 2 the sum of the short diameter and the long diameter). On the other hand, the mass of the granules 17 is proportional to the volume of the granules 17, so it is considered to be proportional to the cube of the representative length of the granules 17. For example, when comparing two types of granules 17 (with the same specific gravity and shape) whose dimensions form a 1:5 ratio, if the same initial velocity is imparted by the user's spraying action, the ratio of the kinetic energies of the granules 17 is 1:5 to the third power, or 1:125, whereas the ratio of the air resistance acting on the granules 17 is 1:5 to the second power, or 1:25. Therefore, the smaller granules are more strongly affected by air resistance than the larger granules.

[0064] In the spray container 20 according to this embodiment, the discharge pipe 4 extends between the gripped part 3 for the user to grip when spraying the granules 17c and the discharge box 5 in which the granules 17c are stored, forming the longitudinal direction of the spray container 20. On the other hand, the magnitude of the rotational momentum imparted to the granules 17c stored in the discharge box 5 by the user's spraying action is proportional to the distance between the point of force (the user's hand, i.e., the position of the gripped part 3) and the point of action (the granules 17c, i.e., the position of the discharge box 5). In the spray container 20, the extension of the discharge pipe 4 ensures a sufficient longitudinal length, so that a sufficiently large initial velocity can be imparted to the small and light granules 17c, and the small and light granules 17c can be made to reach a greater distance than when a spray container according to the prior art is used.

[0065] (Example) As an example, a test was carried out under the following conditions. A spray container 20 was manufactured with the dimensions shown in Fig. 9. The spray container 20 had a minor axis of 1.2 mm, a major axis of 2 mm, and an apparent specific gravity of 0.45 g / cm3. 3 The agricultural composition granules were filled with 200g of the above composition. The number of shakes required to spray all the granules and the amount of discharge per shake were measured for two testers A and B. The test results are shown in Table 1 below.

[0066] [Table 1]

[0067] In the test of the embodiment, the number of shakes required for the spray container 20 to spray all the granules was 10, the same number for both testers A and B. In addition, the standard deviation and coefficient of variation for the average value of the amount discharged per shake (spraying action) were small. In other words, the results of the test of the embodiment revealed that when spraying using the spray container 20, the variation in the amount discharged depending on the user and the shaking method was small, and it was possible to discharge a specified amount.

[0068] Although specific figures are omitted, in the test of the embodiment, the sprayed granules reached a distance of about 4 to 5 m.

[0069] (Action of this embodiment) In this embodiment, a predetermined amount of the granules 17 injected from the injection port 1 is stored in the metered chamber 9 and received in the discharge vessel 5, and when this predetermined amount of granules 17b is sprayed from the discharge vessel 5, the granules 17a stored in the storage chamber 6 does not flow into the metered chamber 9. Therefore, according to this embodiment, it is possible to suppress fluctuations in the amount of spray that depend on the muscle strength of the user who sprays the granules 17 using the spray container 20 and on the way the spray container 20 is swung, and to spray a predetermined amount of granules 17.

[0070] In this embodiment, when a user uses the spray container 20 to spray the granules 17, the partition member 15 and the inclined plate 8 provided in the spray container 20 function to suppress the inflow of the granules 17a from the storage chamber 6 to the metered amount chamber 9. Therefore, according to this embodiment, spraying of an amount of the granules 17c exceeding a predetermined amount from the spray container 20 is reliably suppressed.

[0071] In this embodiment, the metering chamber 9 that stores a predetermined amount or less of granules 17b and the discharge basin 5 that receives and disperses the granules from the metering chamber 9 are located on the opposite side of the storage chamber 6 and the inlet 1 along the longitudinal direction (Z-axis direction) of the spraying container 20. Therefore, according to this embodiment, a sufficient distance is secured between the metering chamber 9 and the discharge basin 5, and the user shakes the spraying container 20 (that is, rotates the spraying container 20 on a plane including the longitudinal direction), thereby obtaining sufficient rotational momentum to spray the granules 17c over a wide area. Then, the user's spraying action gives sufficient rotational momentum to the granules 17c, making it possible to spray the small and light granules 17c over a long distance. When the specific gravity and shape are the same, the air resistance acting on the flying granules 17c is generally proportional to the projected area of ​​the granules 17c, so the magnitude of the air resistance is considered to be proportional to the square of the representative length of the granules 17c (for example, 1 / 2 the sum of the short diameter and the long diameter). On the other hand, the mass of the granules 17c is proportional to the volume of the granules 17c, and is therefore considered to be proportional to the cube of the representative length of the granules 17c. Therefore, the granules 17c with small dimensions are more strongly affected by air resistance than the granules 17c with large dimensions. Therefore, the granules 17c with small dimensions are generally less likely to reach farther than the granules 17c with large dimensions. According to this embodiment, the granules 17c can be given a sufficient initial velocity by the user's spraying operation, so that even small granules 17c can be sprayed farther.

[0072] In this embodiment, the discharge pipe 4, which is partitioned from the storage chamber 6 by the partition plate 7, extends along the longitudinal direction and communicates with the metered amount chamber 9 and the discharge chamber 5. Therefore, according to this embodiment, the internal space of the discharge pipe 4 provides a communication path of sufficient length between the metered amount chamber 9 and the discharge chamber 5, and the granules 17c can be sufficiently widely dispersed from the dispersion container 20 shaken by the user. In particular, according to this embodiment, the small and light granules 17c can be given a sufficient flight distance.

[0073] In this embodiment, when the spraying container 20 is tilted so that the discharge chamber 5 is positioned vertically below the metering chamber 9 on a plane including the longitudinal direction of the spraying container 20, the granules 17b prepared in the metering chamber 9 move to the discharge chamber 5, but the granules 17a do not flow from the storage chamber 6 into the metering chamber 9. Therefore, according to this embodiment, the predetermined amount of granules 17b prepared for spraying can be easily moved from the metering chamber 9 to the discharge chamber 5 by tilting the spraying container 20.

[0074] In this embodiment, the partition member 15, which suppresses the inflow of the granules 17a from the storage chamber 6 to the metered amount chamber 9 when the granules 17c are sprayed, has a slanted plate 8 that partitions a part of the outer edge of the storage chamber 6, extends inside the storage chamber 6, and is inclined with respect to the longitudinal direction of the spraying container 20, and this slanted plate 8 is inclined so as to approach the metered amount chamber 9 as it moves away from the partition plate 7 that partitions the discharge pipe 4 and the storage chamber 6. Because the slanted plate 8 is inclined in this way, when the spraying container is inclined so that the discharge box 5 is located vertically above the metered amount chamber, the slanted plate 8 does not hinder the inflow of the granules 17a from the storage chamber 6 to the metered amount chamber 9 near the partition plate 7, but rather promotes the inflow. Therefore, according to this embodiment, a suitable partition member 15 can be provided which suppresses the flow of granules 17a from the storage chamber 6 into the metering chamber 9 when granules 17c are sprayed from the discharge chamber 5, while not interfering with the preparation of a predetermined amount of granules 17b in the metering chamber 9 by tilting the spraying container 20.

[0075] In this embodiment, the gripped portion 3 is provided for the user to grip when spraying the granules 17c. Therefore, according to this embodiment, it is possible to provide the spraying container 20 which is suitable for the user's operation when spraying.

[0076] In this embodiment, the gripped part 3 for the user to grip has a smaller diameter than the main body 2 of the spraying container 20 that contains the storage chamber 6 and the portion of the discharge pipe 4 extending parallel to the storage chamber 6. Therefore, according to this embodiment, it is possible to provide a spraying container 20 that includes a gripped part 3 that is easy for the user to grip and does not easily slip.

[0077] In this embodiment, the metered chamber 9 and the discharge measure 5 are located on opposite sides of the discharge pipe 4 extending along the longitudinal direction, and the gripped part 3 that houses the metered chamber 9 is located on the opposite side of the discharge measure 5, sandwiching the main body part 2 that houses the storage chamber 6 and a part of the discharge pipe 4. Therefore, when the user grips the gripped part 3, a sufficient distance is ensured from the user's hand to the discharge measure 5 by the discharge pipe 4 extending in the longitudinal direction. Therefore, according to this embodiment, the user shakes the spray container 20 (i.e., rotates the spray container 20 on a plane including the longitudinal direction), and a sufficient rotational momentum is obtained to spray the granules 17c from the discharge measure 5 over a wide area. In particular, according to this embodiment, a sufficient flight distance can be given to the small and light granules 17c.

[0078] In this embodiment, the ceiling 10 of the metered amount chamber 9 prevents more than a predetermined amount of granules 17a from flowing from the storage chamber 6 into the metered amount chamber 9. Therefore, this embodiment reliably prevents more than a predetermined amount of granules 17b from being prepared in the metered amount chamber 9 and finally being sprayed from the discharge chamber 5.

[0079] In this embodiment, the maximum amount of granules 17b prepared in the metering chamber 9 and finally sprayed from the discharge vessel can be changed. Therefore, according to this embodiment, the amount of spraying from the spraying container 20 can be changed.

[0080] In this embodiment, the user operates the dial 13 from the outside, and the bottoms 9a and 9b of the metered amount chamber 9 are moved in the positive and negative directions of the Z axis (in both directions along the longitudinal direction) via the rotation of the rotating shaft 14. When the bottoms 9a and 9b of the metered amount chamber 9 are moved, the amount of granules 17 that the metered amount chamber 9 can accept is changed. Thus, according to this embodiment, a spraying container 20 is provided that allows the spraying amount to be changed by a simple operation.

[0081] In this embodiment, the partition member 15 including the ceiling portion 10 of the metered amount chamber 9 is configured to be movable in the positive and negative directions of the Z axis (in both directions along the longitudinal direction). When the ceiling portion 10 of the metered amount chamber 9 is moved, the amount of granules 17 that the metered amount chamber 9 can accept is changed. Thus, according to this embodiment, a spraying container 20 is provided that allows the spraying amount to be changed.

[0082] In this embodiment, the spraying container 20 is used to spray an agricultural composition formed as granules 17. Thus, according to this embodiment, a spraying container 20 capable of spraying a predetermined amount of pesticide, fertilizer, or the like is provided.

[0083] In this embodiment, the granules 17 are water surface floating self-diffusing granules used for agricultural purposes. Therefore, according to this embodiment, for example, a predetermined amount of herbicide can be sprayed on a paddy field.

[0084] In this embodiment, the granules 17 have a minor axis of 0.8 mm or more and 2.0 mm or less, a major axis of 0.8 mm or more and 15 mm or less, and an apparent specific gravity of 0.30 g / cm 3 More than 0.60g / cm 3 According to this embodiment, the size of the sesame seed is about the same as that of a sesame seed, and the specific gravity is 0.5 g / cm3 or less. 3 It is possible to spray a predetermined amount of granular agent such as
