The blank 5 is formed by punching (or cutting out) the blank sheet 2 with a cutter machine or the like as described later.

The blank sheet 2 is made by depositing a metal such as aluminum on a resin film (PET (PolyEthylene Terephthalate) resin or PVA (PolyVinyl Alcohol) resin) (hereinafter referred to as a vapor-deposited film), such as thick paper or white paperboard. It is attached to the surface of the pulp paper (base sheet) of. In the case of a general thin-film deposition film, the layer thickness is about 10 to 20 μm. The thin-film film is bonded to the blank sheet 2 only on the front surface side to form a layer of the thin-film film, and the back surface side of the blank sheet 2 is exposed on the back surface of the pulp paper. The blank 5 is formed from the blank sheet 2 so that the surface side thereof is the surface side of the blank sheet 2. In the present embodiment, the case where a vapor-deposited paper having a layer of a vapor-deposited film formed on the surface of the pulp paper is used as the blank sheet 2 will be described as an example. It can be widely applied to a blank sheet 2 in which a layer having difficulty in adhesion is formed on the surface of the base sheet, such as foil paper in which a metal layer such as aluminum foil is bonded to the surface of the base sheet.

Since the back surface of the blank sheet 2 (or the blank 5) (the back surface of the pulp paper) is exposed, the back surface of the pulp paper is exposed, so that the adhesive (hot melt, etc.) is impregnated well and the adhesiveness is excellent. Alternatively, the front surface of the blank 5), that is, the front surface of the vapor-deposited film, has poor adhesive impregnation property as compared with the back surface, and it is difficult to secure the adhesive strength required for assembling and sealing the packaging box 10.

The modes (shape, size, etc.) of the second knob portions 521a and 521b shown in the figure are merely examples.

On the + y side of the second picking portion 521a (the side opposite to the side where the second peeling region 52 of the second picking portion 521a exists), it functions as a finger hook when picking up the second picking portion 521a. A rectangular second finger hook hole 522a is formed. Further, on the −y side of the second knob portion 521b (the side opposite to the side where the second peeling region 52 of the second knob portion 521b exists), a finger is hooked when the second knob portion 521b is picked up. A rectangular second finger hook hole 522b that functions as a function is formed. The modes (shape, size, etc.) of the second finger hook holes 522a and 522b shown in the figure are merely examples.

As shown in FIG. 7, for the vapor-deposited film of the first peeling region 51, for example, a finger is inserted into the first finger hook hole 512a from the surface side of the blank sheet 2, and the first pinching portion 511a is pinched to obtain −y. By pulling along the direction, it can be easily peeled off along the first half-cut lines 515a and 515b. As described above, the thin-film film in the first peeling region 51 can be removed by a simple operation.

If the thin-film deposition film is torn off during the peeling process, or if the film-deposited film fails to be peeled off during the process, insert your finger into the other first finger hook hole 512b and pinch the first knob portion 511b to remove it. By pulling along the + y direction, the peeling of the vapor-deposited film can be attempted again. Even if the peeling fails in this way, the peeling can be attempted again, so that the vapor-deposited film can be reliably peeled from the first peeling region 51.

The vapor-filmed film in the second peeled area 52 can also be removed by the same method as in the case of removing the thin-film film in the first peeled area 51.

FIG. 8 shows the state of the blank sheet 2 after the vapor-filmed film of the first peeled region 51 and the thin-film film of the second peeled region 52 are peeled off. As shown in the figure, by peeling off the thin-film film in the first peeling region 51 and the thin-film film in the second peeling region 52, the thin-film film removal target region of each blank 5, that is, the insertion portion 151. The vapor-deposited film in the shaded region G1 on the surface and the shaded region G2 on the surface of the insertion portion 161 is removed, and the surface of the pulp paper is exposed in the shaded region G1 and the shaded region G2.

By the way, in the above, the first peeling area 51 and the second peeling area 52 have been described as being manually removed, but for example, the picking areas (first picking portions 511a, 511b, second picking) by a manipulator or the like have been described. The first peeling area 51 and the second peeling area 52 may be automatically removed from the blank sheet 2 by using a machine, such as by picking and peeling the knuckle portions 521a and 521b).

Further, in the above, the case of removing the vapor-deposited film of the shaded region G1 or the shaded region G2, which is the region to which the adhesive is applied, has been described as an example. Can be set arbitrarily. Further, in that case, the arrangement mode of the blank sheet 2 (position and direction in which the blank 5 is provided, etc.) can be arbitrarily set to an optimum state from the viewpoint of improving the productivity of the blank 5, for example.

As described in detail above, according to the present invention, even when the vapor-deposited paper is used as the blank sheet 2 forming the blank 5 of the packaging box 10, the vapor-deposited film in the region to which the adhesive is applied can be easily removed. This makes it possible to secure the adhesive strength required for assembling and sealing the packaging box 10.

The above description is for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be modified and improved without departing from the spirit thereof, and the present invention includes equivalents thereof.
