FIG. 1 shows a paper pack with a window for checking remaining amount according to the present invention. In the figure, reference numeral 1 denotes a container body of the paper pack. The container body 1 is formed by folding a sheet-like paper board material into a rectangular parallelepiped shape and storing a liquid pesticide as a content therein. Of course, the contents stored in the container body 1 are not limited to liquids such as agricultural chemicals but may be powders.
[0010]
The paper board constituting the container body 1 is not shown in the figure, but has a layered structure composed of, for example, [front side] PE / paper / PE / silica vapor-deposited PET / PE [back side] and has a rigid structure. . Further, for example, a layer configuration of [front side] PE / paper / PE / AL / PET / PE [back side] may be employed.
[0011]
Then, on one side surface 1a of the container body 1, a strip-shaped removal cover portion 2 that is vertically long in the vertical direction is provided. The removal cover portion 2 is formed such that a cut 3 having an intermittent structure is formed in the paper board along the outer peripheral edge thereof so that the paper board material surrounded by the cut 3 can be cut. In that case, for example, the paper board material is appropriately cut using a cutting blade, and as shown in FIG. 2, the cut 3 is formed so as to penetrate in the thickness direction of the paper board material.
[0012]
As shown in FIG. 3A, each of the cuts 3 is preferably formed in a slightly long line shape.
[0013]
In addition, as shown in FIG.3 (b), you may form the cut | interruption 3 in the shape of a short broken line except for the up-and-down both ends side. Further, for example, as shown in FIG. 3 (c), each of the cuts 3 may be formed in a substantially ¬ shape in which the upper end is bent inward.
[0014]
On the other hand, as shown in FIG. 2, this paper pack heat-seal 4 a the transparent sheet 4 on the back surface of the paper plate material excluding the back side of the removal cover portion 2.
The transparent sheet 4 has, for example, a layer structure composed of [outside] PE / Ny / silica-deposited PET [inside], and has a structure with improved barrier properties. And this transparent sheet 4 is provided on the removal cover portion 2 so as to seal the cut 3 from the back side.
The transparent sheet 4 can also be formed of a member having a layer configuration of, for example, [outside] PE / OPP / silica vapor-deposited PET [inside].
[0015]
In addition, the scale 5 which shows the residual amount of agrochemicals is provided in the side edge of the removal cover part 2, as shown in FIG.
[0016]
Furthermore, this paper pack is configured to include a release sheet 7 on the surface side of the removal cover portion 2 as shown in FIG. 4 so that the removal cover portion 2 can be cut out more easily.
[0017]
As the peeling sheet 7, for example, a transparent vertically long sheet having a layer configuration of [outside] Ny / PE [inside] is used, and as shown in FIGS. 5 (a), (b), and (c), the removal cover portion 2 is fixed by heat sealing 7b.
In that case, in order to more firmly fix the peeling sheet 7, a part of the strip-shaped surface portion of the removal cover portion 2 is varnished in advance before the cut 3 is made using the extraction blade , and the varnish removal portion is removed. The peeling sheet 7 is fixed by using .
[0018]
As the peeling sheet 7, for example, [outside] OPP / PE [inside], [outside] Ny / AL / PE [inside], [outside] OPP / AL / PE [inside], [outside] PET / AL / PE Other sheet materials each having an [inner] layer structure can also be used.
[0019]
In addition, it is preferable to provide the knob | pick part 7a in the upper part side in such a peeling sheet 7. FIG . The knob 7a is prevented from being fixed to the paper board material by heat sealing or the like so as to be easily picked by a finger.
[0020]
Now, in the paper pack with a window for checking the remaining amount as described above, the pesticide is stored and stored in the paper pack. In such a case, since the front side of the transparent sheet 4 is protected by overlapping the removal cover portion 2, it is possible to prevent the pesticide from spilling due to the transparent sheet 4 being torn even if a sharp pointed object hits it. .
[0021]
Then, when the agricultural chemical in the paper pack is used later, when it is necessary to check the remaining amount of the agricultural chemical, the end portion or the knob portion 7a of the peeling sheet 7 is picked and the peeling sheet 7 is pulled. Then, the removal cover portion 2 is cut out along the cut 3 so that the transparent strip-shaped window is exposed to the outside. Then, the remaining amount is confirmed by looking at the scale 5.
[0022]
In the illustrated example, the peeling sheet 7 is heat-sealed at the central portion overlapping the removal cover portion 2 and the outer portion is not heat-sealed.
However, although not shown, the entire surface of the peeling sheet 7 may be heat-sealed. In that case, the central portion of the release sheet 7 is fixed to removing the cover section 2 to strengthen for varnish-free, the outer portion is secured to weaken for Ha Igurosunisu.
[0023]
In the above-described example, the peeling sheet 7 is fixed to the entire surface of the removal cover portion 2, but the upper end of the surface of the removal cover portion 2 as shown in FIGS. 6 (a), (b), and (c). The peeling sheet 7 may be fixed only to the part.
[0024]
In the example of FIG. 6, as the peeling sheet 7, for example, a transparent small piece sheet having a layer configuration of [outside] Ny / PE [inside] as described above is used for heat sealing 7 c. Then, when it is necessary to check the remaining amount of the agricultural chemical, the picking portion 7a is similarly picked and the peeling sheet 7 is pulled, and the entire removal cover portion 2 is cut along the cut 3 together therewith.
[0025]
In addition, you may make it cut off the removal cover part 2 by adhering the peeling sheet 7 to the lower end part of the surface of the removal cover part 2. Of course, the peeling sheet 7 described above is not necessarily transparent.
