Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a label for a lid piece that is attached to the outlet of a wet paper packaging bag.

[Prior art and its problems] Conventionally, an annular perforation is made on the top surface of a packaging bag, the perforation is covered with a lid piece whose inner surface is coated with adhesive, and when the lid piece is turned over, the annular perforation is There are known wet paper packaging bags that have a structure in which the part surrounded by perforations is peeled off while remaining adhered to the inner surface of the lid piece, and the outlet is opened. In order to solve the problem that the lid piece is completely separated from the packaging bag when the lid piece is turned over, one side of the lid piece must be fixed to the packaging bag by heat-sealing or the like. To do this, the lid piece also had to be made of synthetic resin film. Therefore, when the lid piece is used as a label, the label must also be made of synthetic resin film, which is a factor in increasing costs.
In order to solve this problem, some paper labels have slits diagonally inward from appropriate locations on both sides of the paper label so that when the label is peeled off, the area beyond the slits does not peel off. If the label was opened and closed repeatedly, it was inevitable that the label would break from the slit.

[Means for solving the problem] In view of this problem, in the present invention, an appropriate openable portion is provided on the upper surface of the packaging bag made of synthetic resin film, etc., and the inner surface is exposed from above. In a package formed by pasting a label coated with a pressure adhesive, a plurality of strips are embossed in a roughly circular shape, leaving the desired width on one side of the label and the part that contacts the openable part. This is a label for a lid piece of a wet paper packaging bag.

[Example] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The packaging bag of the embodiment employing the present invention is made by polymerizing the upper and lower edges of an airtight film such as a synthetic resin film and applying heat sealing to form a cylindrical shape, and wet paper is placed inside the bag. After insertion, both edges are heat-sealed to form an evenly flat packaging bag, and a cut line is formed on the upper surface 2 of the packaging bag 1, which has a substantially V-shaped cross-sectional view, leaving a portion of the film thickness. An annular groove 3 is formed. The annular groove 3 may be round, square, rectangular,
Regardless of the diamond shape, the cut lines may be formed from both sides of the film as shown in FIG. After cutting out the groove 3, the part surrounded by the groove 3 becomes the opening piece 4, and the part excluding the opening piece 4 becomes the outlet 5. A label 7 whose inner surface is coated with a pressure-sensitive adhesive 6 is attached to an area including the periphery of the annular groove 3 (output port 5). The label 7 has an arbitrary width on one side 8 and a part 9 that contacts the annular groove 3,
It has a substantially circular shape and has a plurality of embossments 10, and a pinched portion 11 is formed on the other side. Incidentally, an arcuate break line 1 is formed between the embossed portion 10 and one side 8 (in the following description, the side with the embossment 10 will be referred to as the peeled part 10 and the one side 8 will be referred to as the non-peeled part 8).
2 can be applied to further improve the effect of the non-peelable portion 8.

When opening the package, if you peel off the label 7 using the gripping part 11, the adhesive 6 applied to the inner surface will adhere the inside of the annular groove 3, that is, the opening piece 4 to the inside of the label 7. The annular groove 3 is separated from the
The opening piece 4 is configured so that it is unsealed while being adhered to the inner surface of the label 7 to open the take-out part 5. The peelable part 10 of the label 7 is line-adhesive by embossing, whereas the non-peelable part 8 is fully adhesive, so the label 7 does not peel off completely due to the difference in adhesive strength, and can be used normally. When opening and closing, only the peeling section 10 is configured to open.

[Effects of the invention] As described above, in the present invention, an appropriate openable portion is provided on the upper surface 2 of the packaging bag 1 made of synthetic resin film, etc., and a pressure-sensitive adhesive 6 is further applied to the inner surface from above. In a package to which a label 7 is attached, a plurality of strips 10 are embossed in a substantially circular shape, leaving an arbitrary width 8 on one side 8 of the label 7 and a region 9 that abuts the openable portion. Since this is a label for the lid of a wet paper packaging bag, in order to prevent the lid of a conventional packaging from completely peeling off from the packaging bag, one side of the lid must be attached to the packaging bag by heat-sealing, etc. Because they were stuck, a synthetic resin film had to be used. Therefore, when the lid piece was made into a label, the label was also made from a synthetic resin film, which was a factor in increasing costs. Part 10
The upper surface 2 and the peeled part 10 are line-bonded, and the non-peelable part 8 is entirely bonded, and the difference in adhesive strength increases the effectiveness of the peeled part 10 and the non-peelable part 8. Therefore, there is no need to heat-seal one side, and the label can be made of paper. In addition, even in the case of conventional paper labels, that is, those that have slits diagonally inward from appropriate positions on both sides so that when the label is peeled off, the part beyond the slits does not peel off, the label that becomes the lid piece cannot be used. If the label 7 is repeatedly opened and closed, it is inevitable that the label 7 will break from the slit portion, but in the present invention, there is no such slit and the label 7 will not be torn.
Moreover, if the arc-shaped break line 12 is provided between the peeled part 10 and the non-peelable part 8, the peeling force of the peeled part 10 is reduced by the break line 12, and the peeling does not extend to the non-peelable part 8. In addition, with conventional labels, wrinkles occur at the peeled part when opened and closed repeatedly, resulting in poor sealing performance, but with this invention, since the label is embossed, wrinkles do not occur. Since it is line-bonded with multiple annular embossing strips, it has excellent sealing properties and has little resistance when peeled off, and does not make the crunching sound when peeled off like conventional lid pieces. It has the following effects.
