Description

[Detailed Description of the Invention] The present invention relates to a packaging bag, and more particularly, to a packaging bag that can be opened to facilitate the removal of newspapers and the like when they are wrapped.

No packaging bag has yet been provided that allows newspapers and the like to be easily taken out and opened very easily.

Therefore, an object of the present invention is to provide a packaging bag which has gussets on both sides, and which has a bag opening and a bag bottom so that the upper and lower ends of the gussets partially overlap the folding flap. To provide a packaging bag that can easily form an opening that crosses the packaging bag from the bag opening to the bottom of the bag in order to facilitate the removal of the contents when the contents are packaged in a packaging bag that appears in a stepped manner. .

Hereinafter, the packaging bag of the present invention will be described in more detail with reference to preferred embodiments of the present invention shown in the accompanying drawings.

FIG. 1 shows an embodiment of the packaging bag according to the present invention, with the packaging bag 10 (FIG. 2 or 3) unfolded, in other words, a long piece of paper is shown in the cutting dimension of the packaging bag. The piece of paper obtained by cutting the upper and lower ends in a stepwise manner is designated as a whole by reference numeral 11.

When this piece of paper 11 is formed as a packaging bag 10, it is connected to a wall surface 12.13 that faces each other, and to both side edges of this wall surface, and is connected to bend lines 14a, 14b, and 15a, respectively.
, 15b.

Furthermore, when this piece of paper 11 is formed into a packaging bag 10 by cutting it into a stepped shape, the edge 16 corresponding to the bag opening of the packaging bag 10 has two wall surfaces 12, 136). It has a folding flap 17,
On the other hand, a folding flap 1 is attached to the other wall surface 13 at the edge 18 corresponding to the bag bottom of a similarly formed packaging bag.
It has 9.

When such a piece of paper 11 is formed into a packaging bag 10,
As seen in FIG. 1, the left and right edges of the piece of paper 11 are glued together to form a wall surface 12, a corresponding wall surface 13, and a gusset 14.1.
5 and is formed into a cylindrical shape, and then the widthwise bisecting lines 14c and 15c of the gusset are folded in to form the gusset into a square cross section.

As a result, the opening at the mouth or bottom of the packaging bag has the upper end 20a of the gusset 14.15, as shown in FIG.

21a and the lower ends 20b, 21b partially overlap the folding flap 17.19, i.e. appear stepped.

In such a packaging bag 10, each of the wall surfaces 12, 13
Opening braids 22 and 23 are respectively arranged and fixed on the inner surface of the packaging bag so as to cross the wall surface between the bag opening and the bag bottom.

This is the piece of paper 11 shown in FIG.
, one unsealing braid 22 is arranged on the surface of the wall surface 12 extending linearly from the edge 16 of the folding flap 17 to the opposite edge, and on the other hand, also on the surface of the wall surface 13. 1
The opening braid 23 of the book is attached to the edge 1 of the folding flap 19.
8 to the opposite end edge, and is fixedly arranged and fixed thereto.

Further, on both sides of one end of each unsealing braid 22.23 located on each folding flap 17.19, there is a slight notch 24a from each end edge 16, 1B.
, 24b, 25a, and 25b are formed.

Such cut portions contribute to forming ears 24,25 for making it easier to grasp one end of each of the opening braids 22,23 when opening the packaging bag 10.

However, in forming such ears, a conventional thumb cut may be used.

The arrangement positions of such unsealing braids 22.23 on each wall surface 12° 13 are the ends 20a, 21a,
20b and 21b exclude the part where they overlap with the folding flap 17.19, and the opening string 22.2
3 is placed in a position such that the two strings overlap when the wall surface is viewed planarly (FIG. 2) in the state of the packaging bag 10.

In other words, the terminal end 26 of one unsealing braid (for example, the cord designated by numeral 23) is connected to the other unsealing braid (thus, the cord designated by numeral 22).
It overlaps with the part near the starting end of the string (shown by ).

The reason why the unsealing braid is positioned in the range excluding the edges of the gusset is that hot-melt adhesive is used when producing such packaging bags at high speed, but now the unsealing braid is positioned at the gusset part. If it is placed through the part of the folding flap that overlaps with the end, the pressure applied when forming the gusset on the packaging bag may cause the string to cut the paper, or cause the gusset to break. This may cause problems such as the string sticking to the inner surface of the part.

Moreover, in the part of the folding flap that overlaps with the end of the gusset, the inner end part of the folded double part of the end of the gusset can be torn off together with the opening braid. Because it is impossible to open the package in two, in other words, it is impossible to open the package.

Regarding the formation position of the above-mentioned notch, when you start unwrapping (Fig. 4a), the pasting end 26 (terminal end) of the other unsealing braid 23 will be exposed, so grab it and pull it. A notch 28a to form an ear 27 so that it can be torn.

28b (However, in this case, there are two notches 28a.

28b may be smaller than the width of the ears 24).

According to this, the packaging bag can be opened in two by pulling the unsealing braids 22 and 23 in the flow direction (FIG. 4b).

The packaging bag 10 constructed in this manner is shown in a perspective view in FIG.

When taking out the contents from the packaging bag 10, the opening braid 22 is pulled off by grasping the ears 24, and as a result, the paper portion of the packaging bag 10 is torn as the opening braid 22 is removed.

Next, the unsealing braid 23 is removed from the bottom of the packaging bag 10 in the same manner, and the paper portion of the packaging bag 10 is torn off.

Thereby, the packaging bag 10 is opened as if it were divided into two in the longitudinal direction.

The packaging bag 10 that can be opened in this manner is particularly suitable for wrapping newspapers.

The reason for this is that when taking out the newspaper after wrapping it, the packing bag 1
0 is removed and opened leaving only one hand portion, making it extremely easy to take out.

Moreover, if such a packaging bag 10 is used, the packaging bag 10 can be placed in a basket at a newsstand with one gusset at the bottom, and then the opening braid of the packaging bag can be removed around the circumference, thereby allowing the upper hand of the packaging bag to be removed. Since the side part of the newspaper, that is, the side part of the other gusset part, can be quickly removed and the newspaper part is exposed as it is on the stand, there is no need to open the wrapping paper, organize it, and bundle it as in the past. Stand arrangement work can be done extremely easily.

In addition, when collecting only newspapers at home, it must be done manually, and the packaging bag swells into a cubic shape when the contents are put in. Therefore, one-touch adhesive is used on the front and back sides of the stepped opening. Apply it, insert scissors to the crease line that allows you to secure a flap long enough to close the opening, fold the edge of the gusset first like a normal square bottom bag, then fold the front and back sides and use one-touch adhesive. You can also paste it.

Of course, this packaging bag is suitable for packaging newspapers, but it is not necessarily limited to this, and can also be used to package various contents.

Further, the two opening strings do not necessarily have to be in a straight line, but may be curved in the middle as long as the terminal end of one string overlaps the vicinity of the starting end of the other string.

As mentioned above, the packaging bag of the present invention has gussets on both sides thereof, and has gussets at the bag opening and bag bottom so that the upper and lower ends of the gussets partially overlap the folding flap. The packaged contents can be taken out very easily due to the stepped packaging bag.
