Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sealing seal and a sealing method using the same, and particularly to a sealing seal to be applied across a joint between a lid portion such as an envelope and an envelope body and a sealing method using the same. .
[0002]
[Prior art]
Conventionally, a sealing seal is known in which a plurality of cuts are formed in a seal substrate and an adhesive layer is provided on the back surface. This sealing seal is used by sticking across the sealing mouth that is the joint between the envelope body and the lid, and when opening the envelope, the sealing seal is torn along the notch and tries to close the envelope again. In addition, the sealing seal cannot be applied as it is, so that it can be determined whether or not the envelope has been opened by a third party (for example, see Patent Document 1). In other words, the sealing seal ends its role as a seal when the sealing base material is broken simultaneously with the opening of the envelope.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the sealing for sealing according to the present invention will be described with reference to the drawings. FIG. 1 is a top plan view showing a first embodiment of a sealing seal 1 according to the present invention, FIG. 2 is a rear view of the sealing seal 1 in FIG. 1, and FIG. 3 is a sealing seal in FIG. FIG. 3 is a sectional view taken along line III-III in FIG.
[0016]
As shown in FIG. 1, a plurality of sealing seals 1 are temporarily attached to a long strip-shaped release paper 2 at intervals, and formed into a continuous seal body 3. In the sealing seal 1, perforations 4 (break lines) are formed on a straight line connecting both end portions of the sealing seal 1.
The perforation 4 is a fine cut formed at regular intervals. The narrower the cut and the larger the cut, the easier the cut, and the interval and the size of the cut can be arbitrarily adjusted.
[0017]
As shown in FIG. 2 or FIG. 3, when the release paper 2 is peeled off, an adhesive part 5, a non-adhesive part 6, and a peeling piece 7 are formed on the back surface of the sealing seal 1.
[0018]
The adhesion part 5 (adhesion area | region) is adhesives, such as pressure sensitivity and heat sensitivity, and is formed in the both sides of the non-adhesion part 6 mentioned later.
[0019]
The non-adhesive portion 6 (non-adhesive region) is a region where the adhesive is not applied and is located in the vicinity including the perforation 4.
[0020]
The peeling piece 7 includes two peeling pieces 7a and 7b (first and second peeling pieces) that are symmetrically positioned in a direction orthogonal to the perforation 4 as a center line. Further, as shown in FIG. 3, one end of the peeling piece 7 is firmly bonded by the adhesive portion 5, and the other end is slightly extended to the non-adhesive portion 6. The peeling piece 7 is preferably made of a material that is formed in a conspicuous color such as red or yellow and is strong against pulling.
[0021]
As shown in FIG. 3, the sealing seal 1 includes a sealing base material 8 made of paper having a perforation 4 formed in the uppermost layer, an adhesive portion 5, a non-adhesive portion 6, and an adhesive portion 5 below the sealing base material 8. And the peeling piece 7 is laminated on the lower layer of the non-adhesive portion 6.
[0022]
Next, the usage method of this sealing seal 1 is demonstrated based on FIG.4 and FIG.5. 4A is a view showing a state where the sealing seal 1 is bonded to the envelope 10, and FIG. 4B is a view showing an opened state of the envelope 10.
[0023]
As shown in FIG. 4A, the cover 12 is folded to the envelope body 11 side of the envelope 10 (sealed material) made up of the envelope body 11 and the cover 12 into which the secret document is put, and the envelope body 11 and the cover 12. The sealing seal 1 is attached with the perforation 4 positioned along the sealing opening 13 which is a joint line.
[0024]
Next, as shown in FIG. 4B, when the lid 12 is lifted upward at the time of opening, it is broken from the perforation 4 of the sealing seal 1, and seal pieces 14a and 14b (first seal piece and second seal later) The seal piece is broken.
[0025]
Fig.5 (a) is a top view of the seal pieces 14a and 14b after a fracture | rupture, FIG.5 (b) is a figure which shows the state which peels off the seal pieces 14a and 14b after a fracture | rupture. As shown in FIG. 5A, when the sealing seal 1 is broken into the seal pieces 14a and 14b from the perforation 4 together with the opening of the lid portion 12 of the envelope 10, the first and second extending to the non-adhesive portion 6 are obtained. The tips of the peeled pieces 7a and 7b are exposed.
By holding the tip of the stripping piece 7b that is exposed and lifting it in the direction of the arrow shown in FIG. 5B, the sealing piece 14b is pulled up together with the stripping piece 7b, and the sealing piece 14b can be easily peeled off from the envelope 10. it can. Similarly, the peeling piece 7a is lifted and the sealing piece 14a is peeled off.
[0026]
For example, even if it is attempted to peel off the sealing seal 1 for the purpose of unauthorized opening, it is broken from the perforation 4, so that the sealing seal 1 cannot be applied to the envelope 10 as it is, and it is found that there has been unauthorized opening. . Moreover, since the peeling piece 7 is located in the lower layer of the sealing base material 8, the peeling piece 7 does not appear unless the sealing base material 8 is broken. Therefore, it is not possible to cleanly remove the sealing seal 1 using the peeling piece 7. Is possible.
Therefore, it is proved that the envelope 10 is not opened and the secret of the letter in the envelope 10 is not leaked by handling the letter with peace of mind because the seal 1 for sealing is delivered to the recipient of the envelope without being broken. Can do. When the recipient opens the envelope 10 and breaks the sealing seal 1, the peeled piece 7 is exposed, and the peeled piece 7 can easily peel off the seal pieces 14a and 14b, so that the envelope 10 can be reused. Or it is suitable for recycling use.
[0027]
Further, in the present invention, the shape of the peeling piece 7 is a single straight line having a small width, but it may be any shape in order to make it easy to peel off the sealing pieces 14a and 14b.
For example, FIG. 6 is a rear view of the sealing seal 20 according to the second embodiment of the present invention, in which the first and second peeling pieces 21a and 21b are non-adhesive in a direction perpendicular to the perforation 4. It is formed so as to expand from the portion 6 toward the end of the sealing seal 1 end. Moreover, the thing of the structure similar to 1st embodiment attaches | subjects the same code | symbol, and abbreviate | omits the description.
[0028]
In this sealing seal 20, the areas of the peeling pieces 21a and 21b located in the lower layer of the adhesive portion 5 are formed wider than the peeling pieces 7a and 7b of the first embodiment, and the sealing pieces 22a and 22b are more formed. It is easy to peel off. In particular, when the adhesive part 5 is a strong adhesive having strong adhesiveness, it is preferable to increase the area of the strips 21a and 21b.
Further, since the peeled pieces 21a and 21b are regions having no adhesive force, if the area is made too large, the sealing seal 20 is easily peeled off from the envelope. Therefore, the peeled pieces 21a and 21b are weaker than the adhesive portion 5 in adhesive force. You may form the weak adhesion part (weak adhesion area | region) which has.
As described above, in the second embodiment of the present invention, even if the adhesive part 5 of the sealing seal 20 is a strong adhesive having strong adhesiveness, the peeling pieces 21a and 21b located in the lower layer of the adhesive part 5 Since the area is wide, the seal pieces 22a and 22b can be peeled off more easily.
[0029]
In the present invention, it is also possible to form two rows of perforations located at the boundary between the non-adhesive portion 6 and the adhesive portion 5, and to form opening portions at both ends of the two rows of perforations.
For example, FIG. 7 is a back view of the sealing seal 30 according to the third embodiment of the present invention, and FIG. 8 is a view showing an envelope with the sealing seal 30 attached thereto. Moreover, the thing of the structure similar to 1st embodiment or 2nd embodiment attaches | subjects the same code | symbol, and abbreviate | omits the description.
[0030]
As shown in FIG. 7, the sealing seal 30 has two rows of perforations 31 and 31 parallel to the center in the width direction, and opening portions 36 at both ends of the two rows of perforations 31 and 31.
The unsealing part 36 is a region surrounded by a pair of cutting lines 33a and 33b formed so that the interval gradually decreases from the corners of the sealing seal toward the ends of the two lines of breaking lines, and the cutting lines 33a and 33b. It consists of the non-adhesion part 34 formed in this. In addition, a non-adhesive portion 34 is formed inside the two rows of perforations 31, 31 and is an area excluding the opening portion 36 and the non-adhesive portion 34 formed inside the two rows of perforations 31, 31, which will be described later. An adhesive portion 35 is formed on the seal pieces 32a and 32b. The seal pieces 32 a and 32 b are formed by breaking the sealing seal 30 by the opening portion 36 and the two rows of perforations 31 and 31.
[0031]
Next, a method for using the sealing seal 30 will be described with reference to FIG. At the time of sealing, the non-adhesive portion 34 formed inside the two rows of perforations 31, 31 is positioned so as to follow the sealing opening 13 of the envelope 10, and the sealing seal 30 is attached.
[0032]
If a third party tries to open the envelope 10 illegally, the sealing seal 30 may be broken from the cutting lines 33a, 33b and the perforations 31, 31, and the torn sealing seal 30 may be attached to the envelope 10 as it was. Since this is not possible, it can be determined that there has been unauthorized opening. Further, it is found that the secret of the letter in the envelope has not been leaked by safely delivering the envelope 10 to the recipient without being tampered with, so that the letter can be handled with peace of mind.
When opening the envelope 10, if the opening 36 is held and lifted upward as shown in FIG. 8, the cutting lines 33 a and 33 b and the perforations 31 and 31 are broken. That is, the non-adhesive portion 35 surrounded by the cutting lines 33 a and 33 b is used as a margin for breaking the sealing seal 30. When the sealing seal 30 is broken from the cutting lines 33a, 33b and the perforations 31, 31, the lid 12 of the envelope 10 can be opened, and the seal piece 32a remains on the lid 12 side and the seal piece 32b remains on the envelope body 11 side. . By breaking the sealing seal, the tips of the peeling pieces 7a and 7b located below the sealing pieces 32a and 32b are exposed, and the sealing pieces 32a and 32b can be peeled by lifting the peeling pieces 7a and 7b upward. it can.
[0033]
As described above, in the third embodiment of the present invention, the cutting lines 33a and 33b are arranged so that the distance between the corners of the sealing seal 30 gradually decreases from the corners toward the two perforations 31 and 31 in the center. Since the unsealed portion 36 is formed by using the unsealed portion 34 as a non-adhesive portion 34 as a breaking margin of the sealing seal 30, the region surrounded by the cutting lines 33 a and 33 b is sealed by the unsealed portion 36 and the two rows of perforations 31 and 31. The lid portion 12 of the envelope 10 can be smoothly opened and closed by breaking the seal 30 and opening the lid portion 12. That is, since the sealing seals 1 and 20 described in the first and second embodiments are torn from the perforation 4 simultaneously with the opening of the lid 12 of the envelope 10, for example, the strength of the lid 12 is weak. When the strength of the sealing seals 1 and 20 is strong, a large load is applied when the envelope is opened, so that the lid 12 may be broken. The sealing seal 30 in the third embodiment of the present invention solves this. Therefore, the sealing seal 30 is broken before the lid 12 is opened, and a load is not applied to the lid 12 when the envelope is opened. Therefore, a strong sealing seal is affixed to the weak lid 12. Even if it is done, the envelope 10 can be opened appropriately.
[0034]
Further, in the third embodiment, the strips are the small straight strips 7a and 7b described in the first embodiment, but this is the strip 12a described in the second embodiment. , 12b.
[0035]
Further, in the embodiment of the present invention, the sealed object has been described as the envelope 10, but the present invention is not limited to this. For example, an ampoule bottle or a box may be used as long as it has an arbitrary sealing structure.
Moreover, although the non-adhesion part 6 was made into the area | region which has not apply | coated the adhesive, for example, it is good also as an area | region which gave the printing process and release agent application | coating process which prints to an adhesive and loses adhesive force.
The seal continuum 3 has been described with a plurality of release paper-attached seals temporarily attached to a release paper, but is not limited to this. The release paper is formed in a roll by forming a release agent layer on the upper layer of the seal substrate. It may be a continuous seal without.
Further, for example, printing such as “sealing” or “opening strictly prohibited” may be performed on the surface of the sealing substrate 8.
[0036]
【The invention's effect】
As described above, the sealing seal of the present invention opens the envelope with the sealing sticker by providing the first sealing piece and the second sealing piece with a breakable line in the non-adhesive region. At the same time, since the sealing seal is broken, it is possible to determine whether or not the sealing material has been illegally opened by a third party.
Also, after the envelope arrives at the recipient without being opened illegally, the peeled piece appears by breaking the sealed seal, and the peeled piece easily peels the first and second sealed pieces remaining on the sealed item. Therefore, it is suitable when the sealed material is reused without impairing the appearance of the sealed material. Further, since it is easy to remove impurities such as a sealing base material of the sealing seal and its adhesive, which is a material different from the sealing material, it is also suitable when processing the sealing material as a recycled product.
In addition, by forming the first peeled piece and the second peeled piece in a shape that expands in the direction orthogonal to the breaking line, the adhesive portion can invalidate the adhesive strength of the sealing substrate over a wide range, Even if the adhesive part is a strong adhesive, the first seal piece and the second seal piece can be easily peeled off.
Moreover, even if the first peeled piece and the second peeled piece are provided with a weak adhesive region having a weaker adhesive force than the adhesive region, the areas of the first peeled piece and the second peeled piece can be formed wide. Since the adhesive strength to the sealed object can be secured, the sealing seal is not easily peeled off from the sealed object.
Further, the sealing seal is provided with two rows of perforations and opening portions formed at both ends of the two rows of perforations, and the region surrounded by the opening portion and the two rows of perforations is a non-adhesive portion. By breaking the seal, the cover of the sealed object is opened, and the envelope can be opened without any load when the envelope is opened.
