Abstract

A tamper indicating seal capable of securely indicating the presence or absence of tampering by preventing the dishonest alteration of the tampering indicating seal stamped at a portion to be sealed. In the dishonest alteration which must be prevented, first the tampering indicating seal is cut along an unsealing mouth with a cutter for unsealing. Then, the seal is applied thereto again and a transparent seal for dishonest alteration is stamped thereon to cover the cut part to make the unsealing difficult. Specifically, a rupture layer (2) is formed on the rear surface of a seal base material (1). Tampering is indicated by making the rupture layer (2) breakable when the seal base material (1) is peeled off. Also, a non-bonding treated layer (4) is formed as an outermost layer. By the non-bonding treated layer (4), the seal for dishonest alteration is prevented from being stuck on the seal to alter a tampering indication by the rupture layer (2).

Technical field

[0001] The present invention relates to, for example, an open indication sticker for indicating that an envelope containing a confidential document has been opened in order to prevent the envelope from being opened by a third party.

Background art

Generally, an envelope or the like for containing a confidential document is made to indicate that it has been opened to prevent it from being opened by a third party. For example, as shown in FIG. 5, a paper envelope 101 is sealed by gluing or taping, and a mark 102 is marked on this portion or a seal 103 is marked. As a result, it is possible to recognize that the sheet has been opened because the sealed portion may be damaged at the time of opening, or the seal 102 and the seal 103 may be displaced even if the seal is re-sealed after the opening.

[0003] A resin-made envelope or case that can be used repeatedly for a paper-made envelope on which such one-time use is premised is, for example, a seal as disclosed in Patent Document 1 An anti-open seal is attached to the portion where the This seal is a two-layered structure in which a thin semi-transparent seal and paper are joined by pressure bonding, and once the paper is peeled off the surface of the seal, the paper can not be attached to the surface of the seal again. ing. Patent Document 1: Utility Model Registration No. 3075738 (Paragraph No. 0004)

Disclosure of the invention

Problem that invention tries to solve

[0004] However, the opening prevention seal of Patent Document 1 can be opened by cutting the opening prevention seal along an opening such as an envelope using a cutter, for example, and the cut seal is then cut off. If you align the cut end and attach a new seal from above, you will know that it has been opened. Therefore, it can not be said that the opening preventing seal of Patent Document 1 fulfills a sufficient opening preventing function.

[0005] In view of the above, the present invention aims at providing an opening indication seal capable of reliably indicating the presence or absence of opening. Means to solve the problem

[0006] In order to achieve the above object, the present invention is an opening indication seal for indicating that it is attached to a sealing portion and opened, and the seal is provided on the front side or the back side of the sealing substrate. A breakable layer is provided which is broken when the seal base material is peeled off from the part to be sealed, and further, a non-stick treatment for preventing sticking of the seal for tampering with the tamper evident seal on the outermost layer of the plurality of layers constituting the tamper seal. A layer is provided.

In the above configuration, since the destructive layer which is broken when peeling the display seal from the sealing portion is provided, when the sealing portion is opened, it is displayed that the broken layer is broken and is opened. The destructive layer is a layer that is partially or entirely peeled, cracked, stretched or shrunk when it is opened. The destructive layer is a printing layer formed by various printing techniques such as gravure printing, silk printing, or laminate printing. The printing is applied to the entire surface or a part of the sealing substrate. The printing may be various patterns such as stripes, grids, barcodes, etc., characters such as product indication, symbols, figures, or even colored printing. Colored printing may be performed by using a fluorescent coloring ink that reacts to black light and the like.

[0008] Failure of the destructive layer is achieved by the fact that the printed layer forming the destructive layer is broken by utilizing the fact that the seal substrate on which the destructive layer is formed is stretched at the time of unsealing. There is a mode in which a peeling layer is added and a part of the fracture layer is broken by utilizing the difference in peel strength between a portion with the peeling layer and a portion without the peeling layer.

[0009] When the seal base material is expanded at the time of opening, the printed portion forming the destructive layer is expanded compared to the initial printing, and the printed portion is deformed, thereby indicating that the opening has been made.

[0010] When a release layer is added, a release layer is partially formed on the seal substrate, and then a destructive layer is laminated thereon. Since the adhesive strength between the release layer and the breaking layer is smaller than that of the portion without the release layer, only the release layer adheres to the seal substrate at the time of opening, and the layer portion of the release layer in the breaking layer is destroyed. It will be understood that it was done.

Even in the case of the opening indication seal in which such a destructive layer is formed, the opening indication seal is cut along the opening opening with a cutter or the like to be opened, and then sealed again to cut the opening indication seal. If a transparent tampering sticker is attached to cover the It will be difficult to force. Therefore, in the present invention, by making the outermost layer of the unsealing indication sticker as the non-sticking treatment layer, the tampering sticker can not be attached.

The non-stick layer is a layer to which no other seal can be attached. As the non-sticking treatment, the adhesion strength varies depending on the magnitude of the surface energy, and therefore, a treatment S in which the surface energy necessary for bonding becomes small, such as silicon treatment or fluorine coating treatment, can be mentioned.

Furthermore, even if the non-stick treatment layer is provided, there is a possibility that the non-stick treatment layer is scraped off and removed, and a tampering seal is attached thereon. As a measure to prevent this, a print layer is provided adjacent to the back side of the non-stick treatment layer. Then, when it is attempted to remove the non-adhesive treatment layer with a cutter or the like, part or all of the printing layer is removed at the same time, and a mark to be altered remains.

[0014] In addition, when trying to scrape off the non-stick treatment layer, if the stretchable seal base material is used, the printed layer is stretched by the elongation of the seal base material at the time of peeling off the non-stick treatment layer. It becomes clear. Also, the printing layer can be provided on at least the peripheral edge of the sealing substrate S. If there is a printing layer on the peripheral edge of the sealing substrate, the contour of the opening indication sticker becomes clear and it becomes clear that it has been tampered with if a modification seal larger than the sealing substrate is attached.

[0015] Such a printing layer may be used also as the printing layer forming the destructive layer, or may be printed separately from the destructive layer.

The opening indication seal may have a double seal structure including not only a single seal as described above but also an inner seal and an outer seal. In the case of a single seal, part of the fractured layer destroyed after opening remains on the sealed part of the adherend, which may be contaminated when reusing an envelope, case, etc. In the case of the heavy seal structure, even if the outer seal is peeled off, only a part of the fractured layer remains on the surface of the inner seal, which reduces the possibility of contaminating the adherend. This enables reuse of adherends such as envelopes

[0017] In the method of using the double seal, first, the inner seal is attached to the sealing portion, and then the outer seal larger than the inner seal is attached and sealed. Used on the surface of the inner seal It is possible to create a double seal that can be filled in by forming a layer that a person signs or seals. In such a dual seal structure, a non-stick treatment layer may be formed on the outer seal, and a fracture layer may be formed on the inner seal or the outer seal.

Effect of the invention

As described above, according to the present invention, by providing the non-stick treatment layer to prevent the attachment of the tampering seal, it is possible to prevent the tampering of the opening indication of the destructive layer and to reliably indicate the presence or absence of the opening. It is possible to prevent the opening by third parties such as envelopes containing confidential documents.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, an embodiment of the opening indication seal according to the present invention will be described with reference to the drawings. The open indication sticker in the first embodiment and the second embodiment is intended to prevent the third party such as the envelope 5 containing the confidential document from being opened by a third party, and by sticking it on the part to be sealed, It is designed to display the presence or absence of the opening.

First Embodiment

FIG. 1 is a view showing an opening indication seal according to a first embodiment of the present invention, where (a) is a perspective view of the opening indication seal, and (b) is a cross-sectional view of the opening indication seal attached to a sealing portion. . FIG. 2 is a view showing how the unsealing display sticker of the first embodiment is peeled off.

The opening indication seal includes a seal base 1 made of a transparent and stretchable material, a destructive layer 2 which is broken by the elongation of the seal base 1, and a pattern 3 formed on the peripheral portion of the destructive layer 2. And 4), and the adhesive layer 6 for attaching the opening indication sticker to the envelope 5 or the like, from the outermost layer to the non-adhesive treatment layer 4 and the sealing substrate 1 , The break layer 2 and the adhesive layer 6 are arranged in this order to form a single layer seal.

The seal base material 1 is made of a transparent, stretchable, tear-resistant material such as polyolefin, polyethylene, elastomer, etc., and has extensibility that becomes non-recoverable at a stretch of about 35% or more. The sealing base material 1 has, for example, a circular, unstretched thickness of about 50 zm 100 z m, and extends until it becomes unrecoverable by peeling off at the time of opening.

The destructive layer 2 is a printing layer formed by applying gravure printing, silk printing, laminate printing, or the like on the entire back surface of the sealing substrate 1. The destructive layer 2 is viewed through the transparent non-stick layer 4 and the sealing substrate 1. As shown in FIG. 2, the fracture layer 2 is cracked or deformed in part or the whole surface due to the elongation of the sealing substrate 1 at the time of opening. It has been broken so that it can be confirmed visually, and it becomes clear that it has been opened.

The pattern 3 is composed of a plurality of thin lines formed by making a part of the destructive layer 2 different in color, and is formed on the peripheral portion of the destructive layer 2 and visually recognized through the seal base 1 and the non-sticking treatment layer 4 In some cases, make the outer edge of the opening indication seal clear. Instead of making a part of the destructive layer 2 different in color, the pattern 3 may be formed by over-coating the destructive layer 2.

[0027] The non-sticking layer 4 is a silicon-treated layer or a fluorine-coated layer, etc., and it is impossible to attach another seal to the surface, and tampering with the opened one as if it is unopened. To prevent.

That is, the opening indication sticker is cut by a cutter or the like to open the envelope 5 and the like, and then the opening indication is displayed by re-sealing and attaching a transparent tampering seal so as to cover the cut portion. It is possible to make it difficult to break the seal, and to tamper as if the envelope 5 or the like has not been opened. The non-sticking treatment layer 4 prevents the falsification caused by the application of such a falsification seal. The non-sticking treatment layer 4 can be disposed, for example, on the sealing substrate 1 while removing the shape-retaining material from a tape-like material held by the shape-retaining material from both sides.

It is conceivable that the non-stick treatment layer 4 is scraped off and removed, and a tampering seal is applied. The pattern 3 is broken by the expansion of the seal base material 1 when the non-stick treatment layer 4 is removed. The tampering with the removal of the non-stick processing layer 4 can be overlooked.

In addition, the seal for tampering that is larger than the opening indication seal can be pasted so as to cover the opening indication seal by directly attaching the peripheral portion thereof to the envelope 5, but through the modification seal. Since the pattern 3 can be visually recognized, it can be clearly understood that the tamper seal is overlapped and pasted at a glance by the difference in the size of the opening display sticker and the tamper seal, and the tampering can be viewed.

[0031] The adhesive layer 6 is for sticking the opening indication sticker across the opening of the envelope 5 or the like, and the adhesion is strong adhesive that does not easily peel off, and the adhesive adheres to the adherend when peeled off. It is desirable to have no releasable adhesion. As a result, in the case where the object to be sealed (adherend) is a synthetic resin envelope or case, it is possible to use S again without leaving the adhesive material in a clean state. The present embodiment is not limited to the contents described above, and various changes can be made, such as S. For example, the pattern 3 of the destructive layer 2 may be formed not only on the peripheral portion of the destructive layer 2 but also on the entire surface, and furthermore, it indicates an article sealed only with the purpose of clarifying the peripheral portion. It may be a product display or a bar code pattern. Also, instead of the pattern 3, the seal base 1 and the breaking layer 2 may be colored in a color different from that of the envelope 5. The coloring of the destructive layer 2 may be made by a fluorescent coloring ink which reacts to black light or the like.

Instead of forming the pattern 3 on the destructive layer 2, a printed layer may be provided separately from the destructive layer 2 to represent the pattern 3. This printed layer may be formed on the back surface side of the sealing substrate 1, and may be interposed between the surface side of the sealing substrate 1 and the non-adhesive treatment layer 4. As a result, by scraping off the non-stick layer 4, even the print layer is scraped, and it is possible to see a change due to the removal of the non-stick layer 4.

The fracture layer 2 may be formed on the surface side of the seal substrate 1. In this case, the non-sticking layer 4 is formed on the surface of the fracture layer 2. The shape of the opening indication seal is not limited to a circle, and one having a desired shape may be used by peeling it from the release paper. In addition, a peeling layer may be partially provided between the destructive layer 2 and the sheath substrate 1. As a result, when the seal base 1 is peeled off, a part of the breaking layer 2 adheres to the seal base 1 and is removed, and the breaking layer 2 is totally broken.

[0035] By applying a tension to the opening indication seal, the cutting portion may be propagated to the entire seal when the opening indication seal is slightly cut. Also in this case, since the non-sticking treatment layer 4 prevents the attachment of the tampering seal, it is possible to prevent the tampering seal from restricting the propagation of the cut portion.

Second Embodiment

FIG. 3 is a view showing an opening indication seal according to a second embodiment of the present invention, wherein (a) is a perspective view of the opening indication seal, and (b) is a cross-sectional view of the opening indication seal attached to the sealing portion. . FIG. 4 is a view showing how the opening indication seal of the second embodiment is peeled off.

This opening indication seal is composed of, for example, a circular inner seal 7 and, for example, a circular, larger seal than the inner seal 7, and an outer seal 8, and completely seals the inner seal 7 attached to the sealing portion. By attaching the outer seal 8 so as to cover, when opening, only the outer seal 8 first And the breaking layer 9 is broken to indicate that it has been opened.

The inner seal 7 is formed by partially interposing the release layer 11 on the surface of the inner seal base material 10 made of a hard-to-break material such as polypropylene or polyethylene and forming the fracture layer 9, as well as the inner seal base material. An adhesive layer 12 is formed on the back surface of 10.

For example, 9PP mail 63 (Toyo Ink Mfg. Co., Ltd.) or the like suitable for entry with an aqueous pen is printed, and a person who seals on the surface can enter a sign 13 or the like. It has become so. The destructive layer 9 is formed by gravure printing the entire surface or a part of the inner seal substrate 10. Instead of gravure printing, other printing methods such as silk printing and laminate printing may be used.

The release layer 11 is formed, for example, by gravure printing or silk printing on a part of the inner seal base material 10 using, for example, S1339HP release varnish (Toyo Ink Mfg. Co., Ltd.). The release layer 11 can be formed in various planar shapes.

In the outer seal 8, the non-sticking layer 16 is provided on the entire front surface while interposing the print layer 15 in the peripheral edge portion of the seal base 14, and the adhesive layer 17 is formed on the back side of the seal base 14. Become.

As shown in FIG. 4, when the outer seal 8 is peeled off, only a portion of the fracture layer 9 of the inner seal 7 with the peeling layer 11 adheres to the outer seal 8 and is removed, and the fracture layer 9 is entirely removed. As destroyed. The adhesion of the adhesive layer 17 of the outer seal 8 is set to be weaker than that of the adhesive layer 12 of the inner seal 7, and when the outer seal 8 is peeled off and opened, the inner seal 7 may peel off. It is preventing.

[0043] The seal base 14 of the outer seal 8 is made of a transparent, easily stretchable material such as polyolefin, polyethylene, elastomer or the like, and has extensibility that can not be recovered by an elongation of 35% or more. It is assumed.

When the outer seal 8 is peeled off, the fracture layer 9 is broken by the release layer 11 of the inner seal substrate 10 and the adhesive layer 17 of the outer seal 8, and the seal substrate 14 is stretched. As a result, after the opening indication seal is peeled off and opened, the seal is re-sealed and the opening indication seal is attached again, but the extent to which the inner seal 7 and the outer seal 8 can be visually confirmed by the expansion of the seal base 14 Because it is misaligned, it is possible to overlook the reattachment of the opening indication sticker. The printed layer 15 has a linear pattern that enhances the visibility of the outer edge of the outer seal 8, for example, the range from the outer edge of the outer seal 8 to the inside of the circle corresponding to the outer edge of the inner seal 7. Provided in That is, the print layer 15 is formed from the outer edge of the outer seal 8 to the portion covering the inner seal 7. As a result, even if the outer seal 8 is cut and removed along the outer edge of the inner seal 7, the pattern of the print layer 15 remains in the portion covering the inner seal 7, so that it is covered with a tampering seal and altered. You can easily spot the tampering when you

The non-sticking treatment layer 16 has the same function as the non-sticking treatment layer 4 of the first embodiment. If it is attempted to remove this non-stick treatment layer 16 by scraping etc., in addition to the breakage of the print layer 15 due to the expansion of the seal base 14 at that time, the non-stick layer is also broken by scraping the print layer 15. Tampering due to removal of processing layer 4 can also be easily discerned.

[0047] The adhesive layers 12, 17 of the inner seal 7 and the outer seal 8 are for sticking the open indication seal across the opening of the envelope 5 or the like, and the strong adhesion which is not easily peeled off and the peeled off It is desirable to use re-peelable adhesion so that the adhesive does not stick to the adherend during the treatment. As a result, in the case where the object to be sealed (adherend) is a synthetic resin envelope or case, it is possible to reuse them in a clean state without leaving the adhesive.

The present embodiment is not limited to the contents described above, and various changes can be made, such as S. For example, the breaking layer 9 may be formed on the outer seal 8 and the elongation of the outer seal 8 may cause the breaking layer 9 to break. The destructive layer 9 is not necessarily used as a sign on its surface. The shape of the inner seal 7 and the outer seal 8 is not limited to a circular shape, and may be a star shape, a square shape, a band shape, or the like. Color the seal base 14 to make the outer edge of the outer seal 8 clear.

[0049] By dividing the inner seal 7 along the opening opening, the opening opening may be pierced to prevent the tearing layer 9 from being opened without breaking it. In other words, if the inner seal 7 consists of a sheet of seal covering the opening opening, carefully open the opening opening of the envelope 5 without peeling the outer seal 8 and open it on one side of the opening opening. The remaining inner seal 7 and outer seal 8 may be peeled off from the other side of the opening without overlapping. Therefore, the inner seal 7 is divided into the other of the opening by dividing it. Since a piece of the inner seal 7 remains, the destructive layer 9 on the surface can be reliably destroyed.

Industrial applicability

The opening display sticker of the present invention prevents the opening by a third party such as an envelope, file, or storage box for storing confidential documents, prevents the opening of a portion prohibiting the opening of precision parts, etc., writes a CD case, etc. It can be used for sealing of

[0051] Further, it can be used as a tape in simple packaging of goods. Furthermore, a product name and a bar code can be described to have a function as a tape for simplified packaging, an opening prevention function thereof, and a display function of the product name and the bar code.
