Abstract

PURPOSE:To realize a sealing which can seal and unseal a lid of a bag repeatedly. CONSTITUTION:A permanent adhesive 2 is fixed on one surface of a first sealing sheet 1 and a releasing paper 3A and 3B is attached to respective end surface of the first sealing sheet 1 excluding the central part, on which one surface of a second sealing sheet 4 is mounted unpeelably. A peeling adhesive 5 is fixed to the other surface of the second sealing sheet 4. By using a sealing sheet additionally attached with another releasing paper 6, one end surface of the first sealing sheet 1, whose releasing paper 3A, for example, has been peeled off, is fixed unpeelably through the permanent adhesive 2 on a lid 8 of a bag 7. On the other hand, the other surface of the second sealing sheet 4, from which the releasing paper 6 has been peeled off, is attached unpeelably to the releasing paper 5, and then, an end part of the first sealing sheet 1 is folded inwardly and attached with the permanent adhesive 2 to form a handle 9.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for sealing an envelope, a bag, other paper with a lid, a bag made of synthetic resin or a synthetic sheet, or a case (hereinafter referred to as bags).

[0002]

2. Description of the Related Art Conventional envelopes of this kind, bags with lids, etc., are provided with a crease on the lid and glued on the inside of the lid.
It is fixed with scotch tape, adhesive or adhesive tape so that it cannot be peeled off.

[0003]

In the above-mentioned conventional example, since the lid portion is cut with scissors or a knife at the time of opening and is opened again, when it is necessary to reseal, the opening is made with a cellophane tape or the like. Therefore, there is a problem in that it is not convenient.

[0004]

In order to solve the above-mentioned problems, the method of the present invention is to fix a permanent adhesive 2 or a pressure-sensitive adhesive to one surface of a first encapsulating sheet 1, and to fix both end surfaces excluding the central part thereof. Release papers 3A and 3B are attached to the same, one surface of the second sealing sheet 4 is non-separably attached to the central portion thereof, and a release adhesive 5 or an adhesive agent is attached to the other surface of the second sealing sheet 4. A sealing sheet which is fixed and has release paper 6 attached thereto is used, and a lid 8 for bags 7 is used.
Then, one of the release papers 3A is peeled off, and one end surface of the first sealing sheet 1 is permanently fixed with a permanent adhesive 2 or an adhesive,
The release paper 6 is peeled off from the bags 7 and the other surface of the second sealing sheet 4 is releasably attached with a peelable adhesive 5 or a pressure-sensitive adhesive.
The end portion of the encapsulating sheet 1 is folded back inside and attached with a permanent adhesive 2 or an adhesive to form a knob portion 9.

[0005]

Since the method of the present invention has the above-described structure, the second sealing sheet 4 portion can be peeled from the bag 7 by pulling the knob portion 9, and the lid 8 of the bag 7 can be reopened. You can do it. Further, by pressing the second sealing sheet 4 portion against the bags 7, it is possible to reseal with the peelable adhesive 5 or the adhesive.

[0006]

1 (A) to 1 (D) are explanatory views of one embodiment of the method of the present invention. FIG. 2 is a cross-sectional view showing an example of bags sealed by the present method. In this method, the permanent adhesive 2 is fixed to one surface of the first encapsulating sheet 1, and release papers 3A and 3B are attached to both end surfaces of the first encapsulating sheet 1 excluding the central portion thereof, and the second encapsulating sheet 2 is attached to the central portion. 4 is attached to one surface of the second sealing sheet 4 in a non-separable manner, a release adhesive 5 is fixed to the other surface of the second sealing sheet 4, and a release paper 6 is attached to this (see FIG. 1A). ) Is used. One release paper 3A is peeled off from the lid 8 of the bags 7 and one end surface of the first sealing sheet 1 is fixed with the permanent adhesive 2 so that it cannot be peeled off. 2 The other surface of the encapsulating sheet 4 is releasably attached with a releasable adhesive 5, and the end portion of the first encapsulating sheet 1 is inwardly folded with a permanent adhesive 2 to form a knob portion 9.

Since the present embodying method has the above-mentioned configuration, the second sealing sheet 4 is pulled by pulling the knob portion 9.
The portion can be peeled off from the bags 7, and the lid 8 of the bags 7 can be opened again. Also, by pressing the second sealing sheet 4 portion against the bags 7, it is possible to reseal with the peelable adhesive 5. In the present invention, the permanent adhesive 2 is not fixed to the entire one surface of the first encapsulating sheet 1 as in the embodiment, but the non-adhesive knob portion 9 is left with one surface end left.
May be Also, a company mark or the like may be attached to the surface of the knob portion 9.

[0008]

As described above, according to the present invention, the permanent adhesive 2 or the adhesive is fixed to one surface of the first encapsulating sheet 1,
Release paper 3A, 3B is attached to both end surfaces except the central part,
At the central portion, one surface of the second sealing sheet 4 is non-separably attached, and a release adhesive 5 or an adhesive is fixed to the other surface of the second sealing sheet 4, and release paper 6 is attached to this. Using the sealing sheet formed by the above, one release paper 3A is peeled off to the lid 8 of the bag 7 and one end surface of the first sealing sheet 1 is permanently fixed with the permanent adhesive 2 or the adhesive. , The release paper 6 is peeled off from the bags 7 and the other surface of the second sealing sheet 4 is releasably attached with a peelable adhesive 5 or an adhesive, and the end portion of the first sealing sheet 1 is not adhered. Since the method for sealing bags is characterized in that the knob portion 9 is used, the second sealing sheet 4 portion is peeled from the bags 7 by pulling the knob portion 9, and the lid 8 of the bags 7 is re-attached. It can be opened, and it can be resealed with the peelable adhesive 5 or the pressure-sensitive adhesive by pressing the second sealing sheet 4 portion against the bags 7.
