Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging bag for pesticides, detergents, seeds, furikake, and other powders and granules that can be dropped from the bottom when used.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 6, there is a packaging bag 12 made of a plastic film in which seeds of turfgrass are stored. As shown in the figure, the user makes a hole in the bottom 13 of such a packaging bag 12 with a sharp metal fitting 14 and drops the seed from the hole to use it as a sowing tool as it is. I have something to do.

[0003]

[Problems to be solved by the device]

 The conventional packaging bag as described above is extremely troublesome because the user has to make a hole in the bottom by himself. Therefore, the present invention is an extremely convenient packaging of powder and granules, because the powder and granules stored inside can be easily dropped from the bottom without the user having to do the troublesome work of making a hole in the bottom. The purpose is to provide a bag.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the packaging bag for powder and granules of the present invention has a double bottom, and a small hole 5 for allowing the powder and granules to fall is formed in the inner bottom 3 of the bag. The bottom 4 is characterized in that it can be opened at the time of use in a closed state.

[0005]

[Action]

 When the outer bottom 4 in the closed state is opened, the granular material drops from the small holes 5 previously formed in the inner bottom 3. Therefore, it is not necessary for the user to make a hole in the bottom.

[0006]

Embodiments Embodiments of the present invention will be described below with reference to the drawings. First, FIGS. 1 to 3 show a packaging bag 2 according to the first embodiment in which a herbicide 1 as a powder or granular material is stored. The packaging bag 2 is made of a plastic film and has a double structure having an insole 3 and an outer bottom 4. The insole 3 has a plurality of small holes 5 through which the herbicide 1 can drop. The outer bottom 4 has a structure in which the lower side of the front sheet 6 of the bag and the lower side of the rear sheet 7 are integrally welded to each other and is closed. Above the welded portion 8, scissors or the like is provided. A cut-off line 9 is provided. As shown in FIG. 2, the insole 3 is stored in a folded state, and when the outsole 4 is opened and expanded as shown in FIG. 3, the insole 3 extends horizontally and its small hole 5 is formed. It will be in an open state. Therefore, when the upper end of the packaging bag 2 is gripped and shaken, the herbicide 1 can be sprayed from the small holes 5.

Next, FIGS. 4 and 5 show a second embodiment, which is also a packaging bag 2 containing a herbicide 1. This packaging bag 2 also has an insole 3 and an outsole 4, and the insole 3 has the same structure as that of the first embodiment, as shown in FIG. The outer bottom 4 is composed of an extension portion 10 provided at the lower end portion of the front sheet 6 of the bag, and the tip of the extension portion 10 is folded back to the outer surface side of the rear sheet 7 to form an adhesive 11 for the rear sheet 7. It is glued together. When the adhered folded-back portion of the extension portion 10 is peeled off from the rear sheet 7, the outer bottom 4 is opened, and the herbicide 1 is sprayed from the small holes 5 of the insole 3 as in the first embodiment. You can

In the first embodiment described above, the outer bottom 4 is closed by welding, but even if the outer bottom 4 is closed by adhesion with the adhesive 11, glue or the like as in the second embodiment. Good. Further, also in the case of the second embodiment, the outer bottom 4 may be closed by lightly and peelably welding the extension portion 10 to the rear sheet 7 instead of adhering. Further, in addition to welding and bonding, as a means for closing the outer bottom 4, although not shown, a structure such as a chuck may be provided.

Although the herbicide 1 is stored in the packaging bag 2 in the above-mentioned embodiment, the content is not limited to this, and various pesticides such as pesticides, detergents, seeds and furikake can be used. It is applicable to the body. Further, the material of the packaging bag 2 is not limited to the plastic film, and paper or the like can be used.

[0010]

[Effect of device]

 As described above, the present invention is provided with a double bottom, and a small hole 5 for allowing powder particles to fall is provided in the inner bottom 3, and the outer bottom 4 is closed so that it can be opened during use. Since it is characterized by the fact that the user does not have to do the troublesome work of making a hole in the bottom by himself / herself, simply by opening the outer bottom 4, powder can be obtained from the small holes 5 pre-drilled in the inner bottom 3. Since the particles can be dropped, the work of spraying can be started easily.
