Description

[Detailed Description of the Invention] The present invention relates to a packaging bag made of a soft synthetic resin film such as polypropylene.

2. Description of the Related Art Recently, computer slips have been detachably attached to packaging bags in order to manage the inventory or sales volume of items using computers.

Therefore, by providing a pocket for storing slip paper in the packaging bag, the slip paper can be stored in a predetermined position in the packaging bag, making it easy to confirm the location of the slip paper and also making it easy to take in and take out the slip paper. I was trying to do it.

The present invention relates to an improvement of the slip paper storage pocket in this type of packaging bag, and in particular, to prevent the stored slip paper from accidentally coming out of the pocket, and to make it possible to quickly take out the slip paper from the pocket. This is what I did.

Next, to explain the present invention with reference to an embodiment, in the figure (~), 1 indicates a bag body made of a soft synthetic resin film such as polypropylene, and the bag body 1 is made by folding a sheet of wide film. The bag is constructed by stacking two films or by overlapping two films, and heat-sealing the upper film 2 and the lower film 3 to each other at the left and right edges 4, 4'. The lower film 3 is extended longer than the upper film 2 at the opening of the body 1, and is folded back to the upper surface side of the upper film 2 to form a lid piece 5 that closes the opening, and this lid piece 5 is made even longer. A pocket piece 6 is extended and folded back to the surface of the lid piece 5 (that is, the surface facing outside when the lid piece 5 is folded back onto the upper film 2), and a tip side edge 6a of this pocket piece 6 is formed. is pasted on the lid piece 5 with a pressure-sensitive adhesive band 7, and its inside is formed into a pocket 9 for storing a computer slip 8, and the left and right ends 6c of this pocket piece 6 are cut out. , 6c' overlap with the lid piece 5 at the left and right edges 4, 4' of the bag body 1, a pocket 9 is provided on the surface of the pocket piece 6, the surface of the lid piece 5, or both surfaces. The pocket piece 6 and the lid piece part 5 are coated with printing ink or silicone coated with a length 13 that is approximately equal to the width W2 of the pocket piece 6 and the lid piece part 5.
A thermal fusion blocking means 10 is provided to completely block thermal fusion or to make thermal fusion difficult.

The pocket portion 9 has a wide surface that becomes the front surface when the pocket piece 6 and the lid piece 5 are folded back to close the opening of the bag body. At least one cutting line 11 is provided, and in this embodiment, it is parallel to the front edge 6a of the pocket piece 6 and has a width W.
From the folding line 12 of the pocket piece 6 to the middle W
The cutting line 11 is provided at a position closer to the dimension W, .

In addition, the reference numeral 13 is a pressure-sensitive adhesive band that is attached to the upper film 2 so that it can be opened and closed when the lid piece 5 is folded back onto the upper film 2 to close the opening. The pressure sensitive adhesive band 13 may be provided on the side of the upper film 2, and the reference numeral 14.14 indicates the opening/closing pressure sensitive adhesive band 7,
13, and the cover tape 14 is removable.

Further, the pressure-sensitive adhesive band 7 for pasting the tip side edge 6a of the pocket piece 6 may be provided on either side of the pocket I piece 6 or the lid piece portion 5.

Furthermore, as another embodiment for forming a pocket part, on one side of the lid piece part 5, a separate pocket piece made of an appropriate soft synthetic resin film is provided, and both ends of the pocket piece are attached to the bag body. The pocket piece is arranged substantially parallel to the opening of the bag body so as to overlap the left and right side edges 4, 4, and one of the longitudinal side edges parallel to the opening of the pocket piece is attached to the lid piece 5. The interior thereof is formed into a pocket part 9 into which the computer slip 8 is placed, and a pressure-sensitive adhesive strip is attached to the other longitudinal edge of the lid piece or one side of the pocket piece. It is also possible to form an entrance portion for the slip paper.

The bag body 1 constructed in this manner is continuously manufactured by the two-side seal method as described below.

That is, as shown in FIGS. 4 and 5, while a sheet of soft synthetic resin film is folded in half and transported at an appropriate speed in the direction of arrow A, first, it is placed in a required cylindrical position of the lid piece 5. Bag body 1
The thermal sealing means 10 such as printing ink or silicone coating described above is applied by printing or the like at intervals of the width of the bag.
Further, a pressure-sensitive adhesive band 13 is sequentially formed on the lower surface of the lid piece 5, and a removable cover tape 14 is sequentially stacked and supplied thereon, and a pressure-sensitive adhesive band 7 is sequentially formed on the upper surface of the lid piece 5. Then, cover tape 14 is sequentially overlapped and supplied thereon.

Next, as shown in FIGS. 6 and 7, the pocket piece 6 is folded back at the crease line 12, and after the folding, an upward cutting blade (not shown) is inserted into the lower surface side of the pocket piece 6, and the pocket piece 6 is folded back. A cut line 11 is formed by pressing the cut line 11 from above with a female die or the like (not shown).

After that, while peeling off the cover tape 14, the front edge 6a of the pocket piece 6 is attached to the lid piece part 5 via the pressure-sensitive adhesive band 7.
Then, along the cutting line of line B-B at intervals of bag width,
Manufactured by heat-sealing and cutting at the same time.

In addition, the reference numeral 15 in the figure is a thermal fusion line that is carried out simultaneously with the thermal cutting along the above-mentioned B-B, and is used to thermally fuse the pocket piece 6 to the lid piece part 5 at a center tube approximately the width of the bag. It is something.

In the bag 1 obtained here, the upper film 2, the lower film 3, the lid piece 5, and the pocket piece 6 are separated from the left and right edges 4 of the bag 1 during thermal cutting along the line B-B. , 4' are firmly heat-sealed to each other and formed into a complete bag shape.
The tip side edge 6a of the pocket piece 6 is only attached to the lid piece part 5 with a pressure-sensitive adhesive band 7, and the tip side edge 6a
can be opened.

Then, when the item 16 is placed in the bag 1 and the lid piece 5 is folded over the upper surface of the upper film 2 as shown in FIG. 3, the bag 1 is closed.
Since the pocket piece 6 is on the outside, by opening the tip side edge 6a, the computer slip 8 can be inserted into the pocket part 9. Once this insertion is completed, the pressure-sensitive adhesive strip 7 By closing, the slip 8 does not fall out, and the left and right ends 5c, 5 of the pocket piece 6
A thermal fusion blocking means 10 is interposed between the overlapping portion of c' and the lid piece 5 to prevent the two from being thermally fused as much as possible, as shown in FIG. By inserting a finger into the cut line 11 and pushing the slip 8 in the pocket section 9 toward the heat-sealing cutoff means 10, the front edge paper 8a of the slip 8 can be opened so as to pierce that point. Since the slip paper can be taken out very quickly and easily, sales accounting work at supermarkets and the like can be done quickly.

As in the prior art, the wide surface of the pocket piece 6 is approximately parallel to the side edge 6C of the pocket piece (or the tip side edge 6a of the pocket piece).
In order to provide a perpendicular card ejecting part (perpendicular to the direction) and take out the slip paper in the pocket from this part, the length of this perforated card ejecting part must be longer than the width W3 of the slip line 8. In this case, if the back edge 8a' or the corner of the slip paper 8 gets caught on this card ejecting part and protrudes even a little, there is a risk that the slip paper 8 will be accidentally pulled out.

Furthermore, when the card ejection section is located on the top side of the slip paper 8, the slip paper cannot be taken out any longer in this state. The slip paper had to be shifted to the left or right within the pocket.

However, according to the present invention, at least one cutting line 11 on the wide surface on the front side of the pocket portion 9 is provided in a direction perpendicular to the side edges 5c, 5c' of the pocket so as to face the thermal sealing blocking means 10, so that the slip paper 8 Even if the slip paper 8 is long in the take-out direction and short in the perpendicular direction, the slip paper 8 acts to flatten the thin film-like pocket piece 6 because it is inside the pocket part 9. , the opening is large and wide at the 11th cutting line, and the slip paper cannot be pulled out from there.

Therefore, the cutting line 11 can be made quite long.

Since it is only necessary to press the pad of a finger placed on this long cut line 11 against the top surface of the slip 8 and move it to the right or left, the slip 8 will not be inserted in the pocket section 9 with a slight shift to the left or right or at an angle. There is no problem even if the length of the slip paper is changed.

Moreover, it has the effect of allowing slip paper to be removed extremely easily and quickly.

It should be noted that the cutting lines 11 in the present invention may be plural, and may be not only linear but also wavy, and may be H-shaped or ■-shaped.
