2. Description of the Related Art Conventionally, pesticides have been prepared by diluting an aqueous solution or an emulsion concentrate containing a high concentration of a pesticide active ingredient (active ingredient) to an appropriate concentration with a liquid diluent such as water, or spraying talc or clay. The powder is sprayed by a method such as spraying a powder or granule which is carried on an appropriate solid diluent. In the former case, the work of diluting is necessary, and there is a problem that labor is required to transport the diluting solution to the field or paddy field to be sprayed, and in the latter case, it can be sprayed as it is Although there is an advantage, in the conventional packaging form, there is a problem that it is necessary to divide the necessary amount and transport it to the application place. In addition, many conventional pesticides require a spraying machine according to the dosage form when spraying. This conventional spraying method requires an amount of pesticide corresponding to the sprayer, and there are unavoidable tasks such as dilution of the pesticide at the time of spraying and washing / maintenance of the sprayer after spraying. Was also needed.

[0003]

In recent years, in order to deal with problems such as a decrease in the number of agricultural workers and the efficiency of agricultural management, there has been no need to develop pesticides that require only a small amount of spraying, or to use a special spraying machine. There is a need for pesticides that can be applied by simple methods. In particular, rice transplants are often mechanically transplanted in paddy rice cultivation, and rice seedlings are raised in nursery boxes that are convenient for mechanical transplantation. Pesticides are often treated at the stage of growth in nursery boxes in order to control pests and diseases that occur after transplanting to Honda. However, since the area of the nursery box is small and the seedlings are seedlings, it is necessary to pay close attention to the application amount of the pesticide. The present invention
In response to these demands, an object of the present invention is to provide a pesticide packaging container and a pesticide package that can be packaged in a single application amount and that can be applied directly from the packaging container without requiring a special application machine.

[0004]

According to the present invention, there is provided a container for spraying agricultural chemicals, wherein one open end of a rectangular cylinder formed of a sheet such as paper, cardboard, plastic sheet or the like is formed by a pair of opposing pieces. Folded obliquely toward the inside, the tip of another pair of opposing pieces is integrally bonded and sealed together with the tip of the folded piece into a shape having a rectangular cylindrical body and an inclined portion, A suitable number of pesticide spray holes are provided in a pair of triangular-shaped inclined pieces formed by being folded obliquely and a rectangular cylinder body near the inclined pieces, and the other open end of the rectangular cylinder is appropriately set.

And a spraying part having a triangular cross section formed at one end thereof. The other open end of the rectangular cylindrical body is usually sealed in a flat bottom shape as in the case of the carton, but may be sealed in a triangular shape as in the case of the spraying portion, if necessary.

[0006] The material constituting the container varies depending on the type of the pesticide to be filled, but a thick paper, a material obtained by laminating a metal foil such as an aluminum foil or a plastic film on a rather thick paper, or a plastic sheet can be used. Since paper needs to be strong as a container, cardboard, cardboard or other thick paper, or thick kraft paper is used. Examples of the laminated paper include those obtained by laminating a plastic such as polyethylene on one or both sides of paper, and those obtained by laminating aluminum foil on paper and laminating plastic or coating resin on the aluminum foil surface.

The plastic to be laminated may be appropriately selected depending on the kind of the pesticide to be filled, and any of polyethylene, polypropylene and the like can be used without any particular limitation, but those having chemical resistance and those having thermal adhesiveness are preferred. In particular, a heat-adhesive plastic such as polyethylene is preferable because it can be heat-sealed when manufacturing or sealing a container. For disposal of the used container, a sheet mainly composed of paper is preferred, but the container may be made of a plastic sheet. A sheet of polyvinyl chloride or the like can be used as the plastic sheet.

The spray hole of the container according to the present invention is provided in the triangular inclined piece formed by the folding and the rectangular cylinder body in the vicinity thereof, and the spray hole may be opened in advance. When the container also serves as a container, it is preferable to form the container into a structure that can be opened by a user at the time of use.
The shape of the spray hole may be any of a circle, a semicircle, a square, a rectangle, and a triangle. In the case where the user opens a spray hole, the container wall may be pushed into the container and opened by pressing the hole with a finger, or the container wall may be raised outside the container. Is also good. In the latter case, a cut may be made in the wall of the container to facilitate peeling, or a peeling tape may be attached to the upper surface of the hole. Alternatively, a hole may be formed in the wall of the container in advance, a tape may be attached to a portion including the hole, and the tape may be peeled off.

[0009] The container can be used as a one-way packaging container and a dispensing device, which can be disposable once, or can be used as a dispersing device that uses the container repeatedly. Can be used. When used as a packaging container, as the pesticide to be filled in the container,
Although not particularly limited, usually, solid preparations such as powders, fine granules, granules and the like can be mentioned. In the case of disposables, emulsions, wettable powders, liquid preparations, flowable preparations and the like can be packaged. In addition, it can be applied to application of fertilizers and the like.

At the time of use, a spray hole is opened in accordance with a cut provided in advance in the container, or a tape attached to the spray hole is peeled off to form a hole. Therefore spray.
As a method of spraying, in the case of a nursery box, the applicator simply needs to move the spray container by hand, and in the case of a large spraying place such as a paddy field, the spray container is shaken by hand. Is also good. In view of the above, the spray holes provided in the container should be holes having a size capable of spraying an appropriate amount of the filled pesticide at the time of spraying, or number thereof. In addition, a letter or an identifiable mark (color, symbol, etc.) shall be added near or on the spray hole of the container so that the spray hole or the number of spray holes to be opened can be selected according to the pesticide or application target. You may.
