2. Description of the Related Art A conventional hand-dispersible container for spraying a pesticide wettable powder dissolved in water, such as a granular wettable powder, on a paddy field is of a type in which the wettable powder is dissolved or suspended outside the container and then sprayed. It is a thing. In addition, there is also a type in which a pesticide wettable powder is put into the water from a narrow mouth of the body of the spray container, mixed with water, and then the mixed liquid is sprayed by hand from the narrow mouth.

[0003]

In recent years, the amount of spray liquid per unit area of paddy field has been reduced by hand shaking in paddy fields. In this case, the pesticide wettable powder, for example, a granular wettable powder, is dissolved outside the spray container, and then the solution is transferred to the spray container and sprayed. However, this method has a problem in that two types of containers, one for dilution and one for spraying, are required, and that it is troublesome for diluting and transferring. In addition, some commercially available products already have an aqueous solution formulation, and the method of spraying them is used, but this method facilitates the recovery of used aqueous solution formulation containers to prevent environmental pollution. However, since it is an aqueous solution, there is a problem in that the transportation cost of water in the solution is high. In addition, putting the pesticide wettable powder through the narrow mouth of the container has a problem in that the precautions for preventing leakage to the outside of the container at the spraying site and the complexity of the work therefor. It is an object of the present invention to solve these problems, that is, the problems of transfer of solution, collection and transportation cost of aqueous solution container, and complexity of putting through narrow mouth. Further, it is an object of the pesticide liquid spraying bottle of the present invention to be used for spraying a flowable.

[0004]

The present inventors have found that the problems of the present invention can be solved by providing the following bottles: a wide-mouthed bottle body and a removable lid part on the mouth portion of the bottle body. A bottle for spraying pesticide liquid, comprising: (a) a bottom opening provided with a detachable function portion that can be attached to and detached from the mouth of the bottle body, and (b) the bottom opening is sealed to the liquid outflow plate described below. The liquid outflow plate, which comprises a hollow intermediate part which is opened and closed for stopping and connecting, (c) a liquid outflow plate having 1 to 10 liquid outflow holes, and (d) a closing lid capable of closing or opening the outflow plate. And the area ratio of the inner diameter circle of the mouth of the bottle body is (1: 2) to (1:16), and the ratio of the height from the bottom surface of the lid opening to the liquid outflow plate and the bottom diameter of the lid opening is: (1: 6) to (6: 1)
As described above, the bottle for spraying pesticide liquid agent is characterized in that it is inclined over a part or all of the inner surface of the intermediate part.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the pesticide liquid agent may be any pesticide which is in a liquid or gel form when sprayed, and for example, a wettable powder such as a wettable powder diluted with water. , Flowable, or emulsion or emulsion diluted with water.

FIG. 1 shows a bottle (1) for spraying a pesticide liquid agent of the present invention.
7 to FIG. 7. FIG. 1 is a diagram conceptually showing the positional relationship of each part of the bottle (1) for spraying an agricultural chemical liquid of the present invention. The bottle (1) is a bottle body that is removable from each other.
It consists of (2) and lid (3). The bottle body (2) consists of a detachable function part (4); a body part (18) which may include a grip part (5) and a bottom part (19). The lid (3) is a closed lid (10); liquid outflow plate
(8) (with liquid outflow hole (11)), two connecting parts (2
It consists of an intermediate part (17) containing a part (0) and a beveled inner surface (eg hollow conical cone) (7) and a detachable function part (9) which is a hollow cylinder (6). The bottle body (2) and lid (3) are attached and detached by the attaching and detaching function parts of (4) and (9).

2 to 7 show a bottle (1) for spraying an agricultural chemical liquid of the present invention by a concrete example including an embodiment, in which case a detachable function portion (4) of a bottle body (2) is shown.
Is a male screw, the attaching / detaching function part (9) of the lid part (3) is a female screw, and the closing lid (10) is connected to the liquid outflow plate (8) and the hollow conical cone ((15) via the hinges (151, 152 and 153). It is connected to 7).

The following is a bottle (1) for spraying a pesticide liquid agent of the present invention
Each part of will be described. Detachable functional parts (4) and (9)
May be a part that can be attached and detached with one touch, such as a combination of male and female threads, a combination of inner and outer surfaces of each other, or a ring-shaped flat surface that can be intimately attached to each other (both from dilution shaking to spraying). Any type of flat surface such as a clasp (for example, a binder clip) may be used. Then, when the lid is seated on the bottle body (2) containing the liquid with one touch, and it is shaken after being brought into close contact with the bottle body (2), the lid and the bottle body (2) are not detached from each other, and the liquid is present between the contact surfaces. It just needs to be prevented from leaking. When the attachment / detachment function parts (4) and (9) are threads, for example, the threads of the mouth of the bottle body (2) may be male threads or female threads, but are preferably male threads.

The bottle body (2) is also a combination of the detachable function parts (4) and (9) in which the inner surface and the outer surface of each part are matched.
The outer or inner surface of the hollow cylindrical part (6) of the lid part (3)
It suffices to match the inner or outer surface of the. One-touch means, for example, in the case of screw combination, when the inner surface of the lid (2) is aligned with the bottle body (2) and then rotated, for example, 1/2 to 1/6 rotation, and the male screw of the bottle body (2) is rotated. (4) and lid
When the threads of the female screw (9) of (3) can be closely contacted and connected to each other, and the lid part (3) and the bottle body (2) are to be separated from each other, it is 1/2 To 1/6 rotation means that they can be separated. Also, in the case of a combination in which the inner surface and the outer surface of each other match, one side having the outer surface can be brought into close contact by simply pushing it into the other or by pushing it while rotating, and in the case of desorption, rotating or rotating. It means that it can be desorbed without being allowed to do so.
A combination of screws is preferable from the viewpoint of ease of molding, high durability and easy attachment / detachment.

The bottle body (2) is a vertically long hollow cylinder having an open upper end and a bottom portion (19) at the lower end. The inner volume thereof is usually 250 to 1200 ml, and the amount of the wettable powder of pesticide contained in the bottle body (2), for example, wettable powder of granules, is, for example, 30 to 500 g. The amount of the liquid in which the pesticidal granule wettable powder that is usually used is suspended or dissolved is 100 to 1.0.
It is about 00 ml.

[0011] If desired, the lower half or 1/4 of the outer surface of the body of the bottle body (2) is gripped, or the diameter of the bottom (19) is larger than the diameter of the body to prevent slipping. It is getting bigger. The grip portion is easy to grip to shake the hand, and the outer circumferential surface is curved or recessed inward of the bottle body (2) so that the gripped container does not come out of the hand.

The outer diameter of the hollow cylinder of the bottle body (2) is usually 4.5 to 9 cm. The inner diameter of the mouth of the upper end is 3
To 7 cm. The large opening is for facilitating the insertion of a bag containing the pesticide wettable powder, for example, a granular wettable powder, or the contents thereof. The minimum diameter of the inwardly curved grip (5) is usually 4.5 to 7.0 cm, but with a diameter suitable for gripping when the lid (3) is attached and detached and sprinkled. I wish I had it. The protrusion of the male screw (4) ridge on the outer periphery of the mouth of the bottle body (2) has a height of 1 to 3 mm, and usually has 2 to 4 ridges, often 3 ridges. Each crest extends about 120 to about 180 ° on the outer circumferential surface, and the crest is adapted to mesh with the internal thread (9) crest on the inner surface of the lid (3) by the rotation of the lid (3). Male screw (4)
The vertical width of the part where there is is 1 to 1.5 cm.

Usually, the bottom portion (19) is curved so as to be recessed inward as it goes from the circumferential portion of the bottom portion (19) toward the center. In order to reinforce the upper end of the bottle body (2) according to a conventional method also on the lower side of the male screw (4), the wall material forming the cylinder is uniformly projected outward.

The attachment / detachment function portion (9) of the lid portion (3) corresponds to the attachment / detachment function portion (4) of the mouth portion of the bottle body (2), and is one-touch seated and closely attached. For example, the male thread (4) on the outer peripheral surface of the mouth of the bottle body (2) corresponds to the female thread (9) on the inner surface of the hollow cylindrical portion (6) at the bottom opening of the lid (3).

The lid part (3) is hollow from the opening to the liquid outflow plate (8), and the middle part is a hollow body which is open at both top and bottom. Set the area of the inner diameter circle at the mouth of the bottle body (2) to the liquid outflow plate.
In order to reduce the area of (8), it is preferable to use the inner surface of the head cone (7) which forms part of the middle part (17), but its horizontal cross section is that of the head cone. It does not necessarily have to be circular, and may have a polygonal shape or a star shape having multiple angles. The diameter of the horizontal cross section at each horizontal portion of the truncated cone may be a corrugated circle that periodically changes due to directional rotation.

As described above, the area ratio of the inner diameter circles of the liquid outflow plate (8) and the mouth of the bottle body (2) is (1: 2) to (1:16), preferably (1: 3) to. (1: 9)
And the ratio of the height from the bottom surface of the lid opening to the liquid outflow plate (8) and the product of the diameter of the lid opening is (1: 6) to (6:
1), the inner surface of the middle part (17) of the lid (3) is inclined at least more than half in order to be preferably (1: 2) to (3: 1), the lid (3) When spraying the pesticide liquid by waving the bottle with the bottom facing down (or diagonally downward), the liquid accumulates evenly on the back side of the liquid outflow plate (8), and the liquid pressure is evenly applied to the back side. The amount of liquid discharged from the device becomes uniform, and the amount of spray liquid can be adjusted by the number of times of hand shaking. Moreover, the range of the ejection angle at the time of outflow of the liquid is narrowed, and the spraying on the target area is more accurate. These are very convenient when the amount of liquid per unit area of the paddy field is small.

The liquid outflow plate (8) at the upper end of the lid (3) is
As mentioned above, 1 to 10 holes (11) for liquid outflow,
It preferably has 2 to 6 pieces. If the number of holes (11) is set to 1, the hole diameter must be made larger than in the case of 2 holes in order to make the amount of liquid discharged by one hand shaking necessary. The amount of liquid discharged by one hand shaking is not stable, and there is a defect that the liquid is discharged and finished even when the hand shaking is not performed. Also, as a result of the liquid agent flowing out, there is no separate air port for returning the depressurized internal pressure of the bottle to the external pressure, so the air inflow and the liquid outflow are performed alternately, and the liquid flow is somewhat steady. It becomes unintended and the liquid outflow is rather difficult to control. When the number of the holes (11) is two or more, at least one of them functions as an air hole, and the outflow of the liquid becomes easy. If the number of holes (11) is more than 6, the hole diameter must be reduced, and as a result, it is difficult for the liquid to flow out, and the discharge amount of the liquid discharged by one hand shake is not stable. If the number of) is increased, the number of protrusions of the following closing lid (10) for closing the hole (11) must be increased, which causes a problem that the molding process becomes relatively difficult and the cost increases.

The lid portion (3) is a closing lid (1) for stopping the liquid outflow from the liquid outflow hole (11) of the liquid outflow plate (8) at the upper end.
0) through the hinge or hinge or string, on top of its lid,
For example on the outer circumferential surface of the upper part of the conical cone (7). The closure lid (10) comprises a plate capable of covering the liquid outflow plate (8), which may have as many protrusions (12) as can close the holes (11) as the holes (11), A frame (13) that can be brought into close contact with the side surface of the liquid outflow plate (8) is attached to the periphery of the plate portion of the closing lid (10). This frame (13) allows the hole (11) closed by the protrusion (12)
Alternatively, the liquid flowing out from the unclosed hole (11) can be sealed and the closed lid (10) can be fixed. In order to make such a close contact, the outer peripheral surface of the upper portion of the intermediate portion (17), for example, the upper portion of the head cone (7) is connected to the closing lid (10) via a hinge, a hinge or a string. When connecting via a string, make the side of the liquid outflow plate (8) a male thread and make the inner surface of the frame (13) that can be in close contact with the side of the plate of the closing lid (10) a female thread that can accommodate the male thread. That is, the closing lid (10) can be a screw lid with an internal thread.

This closing lid (10) is used for dissolving or suspending the pesticide granule wettable powder in water or for resuspending by shaking, and for use for preservation of the residual liquid after spraying the pesticide solution. belongs to. Small claws for hooking fingertips or claws on opposite sides of the hinged or hinged closure lid (10) to facilitate and speed disengagement of the closure lid (10) from the liquid outflow plate (8). -Shaped projection (14) is attached to the upper outer surface of the lid (3) located below the claw-shaped projection for easy and quick hooking, for example, the upper circumference of the head cone (7). The outer surface is preferably slightly recessed.

When the hinge type is adopted, the number of hinges is 1 to 3, and the number of 3 is preferable. One end of the hinge connects to a suitable location on the closure lid (10) and the other end connects to the outer surface of the top of the lid, for example the outer circumference of the upper cone (7). For example, when there are three hinges (15), the three are installed in parallel, one end of each of the hinges (151, 153) on both sides is outside the frame (13) of the closing lid (10), and the other end is a lid portion. Connect to the top of (3), eg the top of the conical cone (7); and the central hinge (152) may be slightly wider than the hinges on both sides (151,153), and may be slightly longer and plate-like. Closing lid (10)
Connected to the central part of the hinge and one side of the connected hinge is a closure lid
It may be located in the plate of (10) and part of the frame (13) deleted, and the other end is at the upper part of the lid part (3), for example, slightly below the upper end of the conical cone (7). And a hinge (152) connected to the central portion of the closure lid (10) replaces a portion of the closure lid (10) when the closure lid (10) is closed.

The diameter of the hole (11) is such that when the closure lid (10) is disengaged, the lid (3) is placed downward and the bottle containing the pesticide solution is placed upright or at an angle upside down. In this case, the diameter is preferably such that the liquid hardly flows out, and the liquid flows out when shaken in an arc shape. The diameter of the hole (11) varies depending on the material and thickness of the plate including the liquid outflow plate (8) and the properties and dilution ratio of the pesticide granule wettable powder used, but the plate thickness is 0.5. If the material is ~ 2mm and the material is polypropylene,
It is usually 1 to 5 mm. If the material and thickness are changed, this diameter range can be selected by experiment.

A female screw is formed on the inner surface of the bottom opening of the lid (3).
If (9) is present, the hollow cylindrical part (6) at the bottom opening is provided with irregularities (16) on the outer circumferential surface, which functions as a slip stopper when the lid part (3) is rotated. The shape of the unevenness may be of a normal type, and the unevenness is repeated parallel to the rotation direction, and each of the concave or convex portions is the whole or part on the outer circumferential surface in the direction perpendicular to the rotation direction. May be extended continuously or intermittently. The shape of the unevenness may be, for example, a wave shape, a sawtooth shape, or a shape in which the convex portions are regularly present in a pulse shape at regular intervals.

The normal size of the portion other than the outflow hole (11) of the lid part (3) may be any size that can correspond to the normal size of the bottle body (2) described above. Naturally, the size of the female thread (9) on the inner surface of the hollow cylinder (6) at the bottom opening of the lid (3) corresponds to that of the male thread (4) on the upper outer surface of the bottle body (2). Must.

The bottom opening of the lid portion (3) and the hollow middle portion (17) which is open at the top and bottom, for example, the annular bottom portion of the conical cone (7) are sealed and connected with each other usually in an annular shape. It is a plate, and also functions as a reinforcing portion for both of them that are sealed and connected.
Similarly, the annular upper end of the head cone (7) and the liquid outflow plate (8) may be sealed and connected by an annular plate, which also functions as a reinforcing portion for both sealed and connected. .

In order to easily understand the volume of the liquid put on the outer surface of the body of the bottle body (2), for example, 50 ml,
It is preferable that a 100 ml and / or 250 ml unit display line is written. There may be a slightly inwardly recessed area so that a label can be attached on the outer surface of the bottle body (2).

The material of the bottle body (2) is usually a thermoplastic material that is easily blow-molded, and is a transparent or semi-transparent cloudy synthetic resin that allows observation of the residual state of the liquid inside the container. A material that does not cause environmental pollution is preferable, and is polyethylene such as high-density polyethylene. This material may be glass. The material of the lid portion (3) is a liquid discharge plate (8) with a fine structure having a hole (11), a material including a closing lid (10) and a hinge, which is easy to be precisely injection molded, such as polypropylene. Is. From the aesthetic point of view, it is possible to color the lid part (3), for example to color it green, blue or red.

It is possible to previously put several bags containing a wettable powder of agricultural chemicals, for example, a wettable powder of granules, in the bottle body (2). This was made possible by expanding the mouth of the bottle body (2). Further, as a result, both of them can be transported together, which saves transportation costs.

As described above, the preferred embodiments of the pesticide liquid spraying bottle of the present invention and its respective parts and the effects thereof have been described. Hereinafter, preferred embodiments of the bottle for spraying the agricultural chemical liquid of the present invention will be collectively described.

[0035]

[Effect of the invention] The main body of the bottle for spraying pesticide liquid is the bottle body (2).
And the lid part (3), the inner diameter of the mouth of the bottle body (2) is increased, and the number of holes (11) for liquid outflow is set to 1 to 10 and the diameter of the holes (11) is changed. Within the range of 1 to 5 mm, and the area ratio of the area of the liquid outflow plate (8) to the inner diameter circle of the mouth of the bottle body (2) is (1: 2) to (1:16), and from the bottom of the lid opening. The ratio of the height up to the liquid outflow plate (8) and the bottom diameter of the lid opening is (1: 6) to (6:
By limiting within the specific range of 1), the following effects can be simultaneously given:

(Effect of Diluting Pesticide Formulation with Water in the Agricultural Chemical Liquid Dispersing Bottle of the Present Invention) Since the pesticide granule wettable powder is mixed with water at the spraying place, transportation costs and container costs related to water are reduced. You can save. It can serve as both an easy-to-use diluting container and an easy-to-use spraying container, and the number of containers can be reduced by at least one. Since the mouth of the bottle body (2) has a wide diameter, water can be put in quickly and easily.

(Effect of spraying the pesticide formulation as it is without diluting it with water in the pesticide solution spray bottle of the present invention)
Since the diameter of the mouth of the bottle body (2) is wide, it is possible to quickly insert the pesticide formulation such as emulsion and flowable. (Effects in both cases of diluting the pesticide formulation with water in the pesticide liquid spraying bottle of the present invention and spraying the pesticide formulation as it is without dilution) Since it has a wide mouth, it contains a pesticide wettable powder such as a granule wettable powder. It is possible to put a separate container in the bottle body (2) beforehand and save the transportation cost. By reducing the area of the inner diameter circular area of the mouth portion to the area of the liquid outflow plate (8), the range of the injection angle at the time of outflow of the liquid to be sprayed is narrowed, and the spraying can be performed accurately in the desired spraying area. The amount of spray can be precisely adjusted to spray the pesticide liquid by hand. It is easy to store the used pesticide liquid.

When the attaching / detaching functional portion is a combination of the male screw (4) and the female screw (9), the attaching and detaching is relatively easy, and the bottle body (2) and the lid portion (3) can be easily molded. If the inclined inner surface of the intermediate part (17) is the inner surface of the hollow head-cutting cone (7) that gradually narrows from the bottom to the upper part, the molding process of the lid part (3) is relatively easy, The liquid flow is collected on the liquid outflow surface. Liquid outlet plate (8) on the lid (3) and bottle body
The area ratio of the inner diameter circle of (2) is (1: 3) to (1 :)
9), and if the ratio of the height from the bottom surface of the lid opening to the liquid outflow plate (8) and the diameter of the lid opening is (1: 2) to (3: 1), the liquid flow is The efficiency is comparatively high because it is concentrated on the outflow surface. A closure lid (10) is connected to the upper outer surface of the hollow head cone (7) via a hinge or hinge or string, and has the same number of liquid outlet holes (11) in the liquid outlet plate (8) and its Providing a projection (12) capable of closing the hole (11) makes it possible to quickly and easily close and open the liquid outflow surface, and at the same time, to provide a projection (12) capable of closing the hole (11) at the time of closing. Can make liquid leakage more complete.

If the number of the liquid outflow holes (11) in the liquid outflow plate (8) is set to 2 to 6, the outflow amount of the liquid and the spraying area can be made more accurate.
