Description

  The present invention seals a sealed object such as an envelope for storing confidential documents, a package for packing a transported object, a container for storing medicines or foodstuffs, and the like, and cannot be restored by a tensile force when peeling from the sealed part. The present invention relates to a seal seal that indicates that the object to be sealed has been opened.

  In general, it is required to prevent opening by a third party by sealing an envelope for storing confidential documents, a package for packaging a transported object, a container for storing medicines or foodstuffs, and the like. For example, patent document 1 is disclosing the seal seal which displays that the to-be-sealed thing was opened by extending when peeling from a sealing part.

FIG. 3 shows a seal seal disclosed in Patent Document 1. This seal seal has a structure in which an adhesive layer 101 is laminated with a stretched layer 103 with a network structure layer 102 sandwiched therebetween and a non-stretched layer 104 that protects the stretched layer 103. By peeling off the sealing seal from the adherend 105, the non-stretched layer 104 is separated, and the stretched layer 103 is stretched unrecoverably without breaking, and the opening of the adherend 105 is displayed.

  However, even if the sealing seal of Patent Document 1 is sealed, the sealing seal can be illegally opened without being stretched by cutting along the opening of the sealing portion with a cutter or the like. After that, by opening the seal sticker and pasting another transparent sticker from above, the unsealed display may be tampered with as if unopened.

  An object of the present invention is to provide a seal seal that can reliably display the presence or absence of opening by preventing tampering of the opening display by sticking a transparent seal.

In order to achieve the above object, the sealing seal according to the present invention is provided with an adhesive layer on the back side of a stretchable sealing base material, and cannot be restored due to a tensile force at the time of peeling from the sealing portion of the sealed object. Te is intended to indicate that after opening to be sealed was on the surface of the sealing substrate, when the affixed transparent seal for opening indicating tampering seal seal opened to be sealed was then cut the seal seal In addition, a glossy part and a non-glossy part that lose the difference in glossiness due to the application of a transparent seal are mixed.

  According to this configuration, since the glossy part and the non-glossy part are mixed on the surface of the seal substrate, the seal seal is cut and opened with a cutter or the like, and then a transparent seal is pasted on the cut seal seal to display the seal. Even if it tries to tamper with, the difference in glossiness between the glossy part and the non-glossy part covered with the transparent seal is lost, so that the sticker of the transparent seal can be easily seen and tampering of the unsealed display can be prevented.

  In other words, if a glossy transparent seal is applied to the seal sticker, the glossy part and the non-glossy part become glossy. If a non-glossy transparent seal is applied to the seal sticker, the glossy part and the glossy part are also glossy. Since there is no feeling, the difference in glossiness between the glossy part and the non-glossy part is lost in any case, and the sticking of the transparent seal can be seen at a glance.

  Here, the degree of gloss is determined by the amount of light that is specularly reflected when light is applied, and can be expressed using the “glossiness” defined in the JIS standard. As long as the glossiness is visually different, it is sufficient.

  As a means of mixing glossy and non-glossy parts on the surface of the seal substrate, there are a method of printing glossy and non-glossy parts on the surface of a single seal substrate using multiple types of ink, and a glossy surface. Only the glossy part is printed on a non-glossy seal substrate and the exposed part of the seal substrate is made a non-glossy part. An example is a technique in which an exposed part is a glossy part.

  In addition, the sealing substrate has a gloss on the surface and has a hole that exposes the sealing portion, and a sealing portion that is exposed from the surface of the substrate and the hole by applying a transparent seal for opening display tampering, and It is also possible to lose the difference in glossiness and to detect the sticking of the transparent seal. The gloss of the surface of the sealing substrate may be such that the sealing part and the glossiness are different from each other visually.

As described above, according to the present invention, the glossy part and the non-glossy part are mixed on the surface of the sealing base material, so that a part with different glossiness is mixed in one sealed seal. When the transparent sticker is pasted, the difference in glossiness is lost and the pasting of the transparent sticker can be overlooked.

  This prevents tampering of the unsealed display due to the sticking of the transparent seal, and can reliably display the presence or absence of the unsealed seal. Can be prevented.

  Embodiments of a seal seal according to the present invention will be described below with reference to the drawings. 1A and 1B are perspective views showing a seal seal according to the present invention. FIG. 1A shows a state where a seal seal is affixed to a seal portion, and FIG. 1B shows a state where the seal seal is peeled off from the seal portion. 2A and 2B are enlarged perspective views of the seal seal, in which FIG. 2A shows the seal seal before tampering, and FIG. 2B shows the seal seal with a transparent seal for tampering open.

  This sealing seal 1 is for sealing an sealed envelope such as an envelope into which a confidential document is put, a transported article, a medicine, a foodstuff, and the like to prevent opening by a third party. The printed layer 3 including the glossy part 3 a and the non-glossy part 3 b is provided on the surface of the material 2, and the adhesive layer 4 is provided on the back side of the seal base 2.

  The seal substrate 2 is made of a material that is easily stretched and is not easily broken, such as polyolefin, polyethylene, or elastomer, and has a stretchability that cannot be restored at an elongation of about 3 to 5% or more. For example, the sealing base material 2 has a rectangular and unstretched thickness of about 50 μm to 100 μm, and the elongation rate when pulled with a force of 1 N / cm is set to 50% to 200%. The seal seal 1 is peeled off at the time of opening to extend until it cannot be restored.

  The printing layer 3 is formed by printing a glossy part 3a representing a fine mesh pattern and a non-glossy part 3b representing another part using two types of ink, and on the surface of one seal substrate 2, A glossy part 3a and a non-glossy part 3b having different glossiness are mixed.

  The adhesive layer 4 is for sticking the sealing seal 1 across the opening 6 of the sealing part 5, for example, a strong adhesive that does not easily peel off, for example, about 1 N / cm to 10 N / cm, and seals when peeled off It is desirable that the adhesive is a removable adhesive that does not leave any adhesive remaining on the part 5. Thereby, when the sealed object is an envelope or a case made of a synthetic resin, they can be used again in a clean state without leaving an adhesive material. In addition, it is good to cover the adhesive layer 4 with a release paper and to protect the adhesive surface until the seal seal 1 is applied to the seal portion 5.

  As shown in FIG. 1, when the sealing sticker 1 attached to the sealing portion 5 is peeled off, the seal base 2 is unrecoverably extended by the tensile force, and the printed layer 3 is broken and the sealed object is opened. To do. In addition, since the expansion | extension of the sealing base material 2 is utilized, the sealing base material 2 can fracture | rupture and can be peeled off without remaining in the sealing part 5, and it can be used repeatedly in a clean state.

  As shown in FIG. 2 (a), the seal 1 can easily recognize that the surface is directly exposed due to the difference in glossiness between the glossy part 3a and the non-glossy part 3b mixed on the surface. Can be done. When the sealing seal 1 is cut and opened with a cutter or the like, and then the transparent seal 7 for tampering is pasted on the sealing seal 1 so as to tamper with the unsealed display as if it has not been opened, FIG. 2 (b) As shown in FIG. 5, the gloss difference between the glossy part 3a and the non-glossy part 3b is lost, and the tampering of the unsealed display can be easily detected. When the transparent seal 7 is not glossy, both the glossy part 3a and the non-glossy part 3b lose glossiness, and when the transparent seal is glossy, the glossy part 3a and the non-glossy part 3b. Both have glossiness.

In addition, this invention is not limited to said embodiment, A change can be suitably added within the scope of the present invention. In addition , by forming a hole that exposes the sealing part on the sealing base material having gloss on the surface, the glossy part consisting of the surface of the sealing base material and the non-glossing part consisting of the sealing part surface exposed from the hole of the sealing base material You may make it mix a part. Also in this case, the application of the transparent seal for tampering with the unsealed display loses the difference in glossiness between the surface of the substrate and the seal portion exposed from the hole, and the application of the transparent seal can be overlooked. Here, the hole formed in the seal substrate may be a single hole or a large number of small holes.

  Alternatively, only the glossy portion may be printed on the sealing base material that is not glossy on the surface, and the exposed portion of the sealing base material may be a non-glossy portion. Alternatively, it is also possible to print only the non-glossy part on the sealing base material having gloss on the surface, and to make the exposed part of the sealing base material a glossy part.

  By adopting a transparent sealing base material, the seal mark such as a sign or seal printed on the seal part can be visually confirmed, or the seal mark such as a sign or seal can be entered on the surface of the seal sticker. Then, it may be possible to prevent a third party from re-applying to another seal seal. In addition to representing a mesh pattern with a glossy portion, a fine character or pattern can also be represented with a glossy portion or a non-glossy portion.

It is a perspective view which shows the seal seal concerning this invention, (a) shows a mode that the seal seal was affixed on the seal part, (b) shows a mode that a seal seal is peeled from a seal part.
