Description

  The present invention relates to a cylindrical label that is used by being attached to a beverage container or the like, and a cylindrical label forming substrate.

Conventionally, a cylindrical label in which a film is formed in a cylindrical shape is used for various applications.
The cylindrical label can be roughly classified into the following three types according to the properties of the film or the method of attaching the adherend to the adherend such as a container.
The first cylindrical label is a cylindrical label formed into a cylindrical shape by overlaying and bonding the back surface of the second other end to the surface of the first side end of the heat-shrinkable film. . This first cylindrical label is also called a cylindrical shrink, a shrink label, or a heat-shrinkable cylindrical label. Hereinafter, in this specification, this type of cylindrical label may be referred to as a “heat-shrinkable cylindrical label”.
The second cylindrical label is a cylindrical label formed into a cylindrical shape by overlaying and bonding the back surface of the second other end to the surface of the first side end of the self-stretchable film. . This second cylindrical label is also called a stretch label or a self-expandable cylindrical label. Hereinafter, in this specification, this type of cylindrical label may be referred to as a “self-expandable cylindrical label”.
The third cylindrical label is obtained by partially bonding the back surface of the first side end of the film to the container, wrapping the film around the container, and forming the second side end of the film on the surface of the first side end. It is a cylindrical label formed into a cylindrical shape by bonding the back surface. This third cylindrical label is also called a wound cylindrical label or a wound label. Hereinafter, in this specification, this type of cylindrical label may be referred to as a “wrapped cylindrical label”.

  By the way, although the said cylindrical label is utilized as a display medium for carrying out general display, such as a brand name, prize application information and 籤 information may be displayed on this. Such prize application information and bag information must be secretly attached to the cylindrical label so that only consumers who have purchased the product can know it. Hereinafter, in this specification, a person who has purchased a product properly is referred to as a “regular purchaser”. In addition, information that should be kept secret, including information that is given as a privilege to a legitimate purchaser, such as prize application information or reward information, may be referred to as “secret information”.

Patent Document 1 has a base material on which a design printing layer is printed on a film, and the back surface of the other side end portion is superposed on the surface of one side end portion of the base material, and the superposed portion is bonded to a predetermined width. By this, it is a cylindrical label formed in a cylindrical shape, a desired printing layer is printed using a non-impact printer on the back surface of one side end portion of the base material, the printing layer, The cylindrical label printed in the region where the design printing layer of the one side end and the design printing layer of the other side end overlap among the overlapping parts of the one side end and the other side end of the substrate It is disclosed.
This cylindrical label has an effect that the display shown on the print layer cannot be seen through from the surface.

However, the cylindrical label of Patent Document 1 can visually recognize the display of the print layer from the back side of the substrate. For this reason, for example, when the cylindrical label is attached to a transparent container filled with a transparent content, there is a problem that the display of the print layer can be seen from the back side of the cylindrical label through the content. is there. In particular, when the cylindrical label is attached to a transparent PET bottle containing mineral water, when the back side of the cylindrical label is viewed from the front side of the container on the side opposite to the printing layer, the display of the printing layer can be easily seen. . Therefore, there is an inconvenience that the consumer can visually recognize the secret information without purchasing the product.
Moreover, a cylindrical label is formed from the base material which has a film as mentioned above. In the case of the cylindrical label, the display of the print layer can be easily seen from the back side of the base material while the base material for forming the cylindrical label is being stored and transported. For this reason, there is a possibility that secret information may be known to a third party other than the manufacturer of the cylindrical label.

  On the other hand, after an authorized purchaser purchases a product, it is necessary to devise so that the authorized purchaser can easily see the display of the print layer by simply opening the cylindrical label.

In the cylindrical label formed in a cylindrical shape, a first masking layer is provided on a part or all of the surface of the first side end of the film, and a desired print layer is formed on the surface of the first masking layer. A second concealing layer is provided on the surface of the print layer, and the first concealment layer and the second concealment layer at least display the print layer in order to conceal the display of the print layer. It is provided correspondingly, and the back surface of the second side end is overlapped and bonded to the front side of the first side end with the first hiding layer, the printing layer, and the second hiding layer interposed. And the interlayer adhesion between the back surface of the second concealing layer and the surface of the printing layer is such that the second concealing layer Surface and less than the interlayer adhesion strength between the back surface of the second end portion.

  Still another cylindrical label of the present invention has a transparent film having a first side end portion and a second side end portion which are band-like regions along the vertical direction, and the film is arranged such that the back surface is inside. In the cylindrical label formed in a cylindrical shape, a desired print layer is provided on a part or all of the surface of the first side end of the film, and the display of the print layer is further provided on the surface of the print layer. A second concealing layer is provided which can conceal the display of the print layer on at least the back surface corresponding to the display of the print layer among the back surfaces of the first side end portions of the film.

If less than the interlayer adhesion strength between the back surface of the second end portion.

Since each cylindrical label of the present invention is provided with the first concealing layer and the second concealing layer on the front and back sides of the print layer, everyone can display the print layer from the front side and the back side of the tubular label. The displayed display cannot be seen.
Therefore, when the cylindrical label of the present invention is used, it is possible to prevent a third party other than the authorized purchaser from knowing the secret information when, for example, a display relating to the secret information is displayed on the print layer.
Furthermore, the cylindrical label of the present invention has the first side end and the second side end bonded together with the second concealing layer interposed therebetween, and their interlayer adhesion is in the above relationship, When the second side end is peeled off from the first side end, the second shielding layer is peeled off together with the second side end.
Accordingly, the display of the print layer hidden by the second hiding layer can be visually recognized from the surface side of the first side end by simply peeling off the second side end.

One preferable cylindrical label of the present invention is easy to reduce the adhesion of the second shielding layer to the surface of the first side end portion between the back surface of the second shielding layer and the surface of the first side end portion. A release layer is interposed.
Such a preferable cylindrical label ensures that when the second side end is peeled off, the second hiding layer and the first side end are surely separated, and the second hiding layer is formed on the surface of the first side end. Some will not remain.

In another preferable cylindrical label of the present invention, the surface of the first side end portion and the back surface of the second side end portion are at least a side edge of the second side end portion and a side edge of the second concealing layer. Directly bonded between them.

The directly bonded portion has a first side end portion and a second side end portion rather than a portion where the first side end portion and the second side end portion are bonded with the second concealing layer interposed. Is strongly bonded.
Therefore, it is possible to prevent the second side end from being inadvertently peeled off from the first side end. On the other hand, when the directly bonded portion is peeled off, the second concealing layer is moved together with the second side end to the first side. It can be peeled off from the end surface.

According to another situation of this invention, the base material for cylindrical label formation is provided.
This base material for forming a cylindrical label has a transparent film having a first side end portion and a second side end portion which are band-like regions along the vertical direction, and the film is formed in such a manner that the back surface is inside.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
However, in the present specification, the “back surface” refers to one surface of a leaf-like body (film, each layer, etc.), refers to the surface that is the inner side when a cylindrical label is formed, and the “front surface” It refers to the opposite surface (the other surface) of the leaf-like body, and refers to the surface that becomes the outside when the cylindrical label is formed.
Further, in this specification, the “lateral direction” is one direction of the cylindrical label forming base material, and corresponds to the circumferential direction of the cylindrical label when the base material is formed on the cylindrical label. The “longitudinal direction” refers to a direction substantially orthogonal to the lateral direction in the plane of the substrate.
It should be noted that the shape, size, thickness of each layer, the relative ratio thereof, and the like shown in each drawing are different from actual dimensions.

[First Embodiment of Base Material for Forming Cylindrical Label]
1 and 2 are perspective views showing a first cylindrical label-forming substrate 1 of the present invention, and FIG. 3 is a cross-sectional view taken along line III-III in FIG.
This base material 1 for forming a cylindrical label is a base material for forming a cylindrical label, and a cylindrical label can be formed by rounding it to form a cylindrical shape.
As described above, the cylindrical label can be roughly classified into a heat-shrinkable cylindrical label, a self-expandable cylindrical label, and a wound cylindrical label according to the properties of the film or the attachment method to the adherend such as a container.

  Each of these cylindrical labels is common in that the base material is formed in a cylindrical shape. The difference is that the heat-shrinkable cylindrical label is formed from a base material having heat-shrinkability (property that shrinks in a predetermined direction when heat is applied), and is formed into a cylindrical shape before being attached to the adherend. The self-stretching cylindrical label is formed from a base material having a self-stretching property (a property that expands when pulled and returns almost to its original shape when the tensile force is released) and is attached to the adherend. Formed from a base material having heat shrinkability or self-stretchability, or a base material not having heat shrinkability and self-stretchability, and being attached It is to be formed into a cylindrical shape when wrapped around the body and mounted.

The base material 1 for forming a cylindrical label of the present invention can be used as a base material for forming any one of the above-described cylindrical labels by appropriately selecting the properties thereof.
By making this cylindrical shape so that the back surface of this cylindrical label forming base material 1 is inside, by overlapping and adhering the second side end portion 12 to the surface side of the first side end portion 11, A cylindrical label is obtained.

The said cylindrical label formation base material 1 has the film 2 of planar view substantially rectangular shape.
In the mechanical production process, the cylindrical label-forming base material 1 is usually manufactured as an elongated base material continuous body in which a plurality of cylindrical label-forming base materials 1 are continuously connected. In use, each continuous body 1 for forming a cylindrical label is obtained by cutting the continuous body into a predetermined length.

As the film 2, a transparent film is used in order to visually recognize the display of the print layer 3. In addition, the transparent film should just be a film which has translucency which can visually recognize the display of the printing layer 3 through the film 2. FIG. Therefore, the transparent film may be colored as long as a person can visually recognize the display of the print layer 3.
The film 2 may or may not have at least one of heat shrinkability and self-stretchability. What is necessary is just to select the film 2 of the base material 1 for cylindrical label formation according to the classification of a heat-shrinkable cylindrical label, a self-expandable cylindrical label, or a winding cylindrical label.

  The material of the film 2 is not particularly limited. In the case of a film having heat shrinkability, for example, a polyester resin such as polyethylene terephthalate, an olefin resin such as polypropylene, a styrene resin such as a styrene-butadiene copolymer, a cyclic olefin resin, a vinyl chloride resin, etc. The stretched film containing the thermoplastic resin of this is mentioned. In the case of a film having self-stretchability, examples thereof include a film containing an olefin resin such as polyethylene and a thermoplastic resin such as ethylene vinyl acetate copolymer. The self-stretchable film may have heat shrinkability in addition to self-stretchability. In the case of a non-heat-shrinkable and non-self-stretchable film, examples thereof include a biaxially stretched polyester film, a biaxially stretched styrene film, and a biaxially stretched olefin film.

The substantially rectangular film 2 has a first side end portion 11 along the vertical direction and a second side end portion 12 along the vertical direction that faces the first side end portion 11 in the horizontal direction. . The first side end portion 11 is a band-like region that includes a first side end edge 11 a along the vertical direction and extends in the vertical direction from the upper edge to the lower edge of the film 2. The second side end portion 12 is a belt-like region that includes a second side end edge 12 a along the vertical direction and extends in the vertical direction from the upper edge to the lower edge of the film 2. The said 1st side edge part 11 and the 2nd side edge part 12 comprise the overlapping part overlapped when forming a cylindrical label. A cylindrical label can be configured by superimposing the back surface of the second side end portion 12 on the surface side of the first side end portion 11 and bonding all or part of the overlapped portion.
The lateral width (that is, the lateral width of the overlapping portion) of the first side end portion 11 and the second side end portion 12 is not particularly limited, but is usually 3 mm to 20 mm, preferably 5 mm to 15 mm. The horizontal width is a length in the horizontal direction.

A design printing layer 4 is provided on at least one of the back surface and the front surface of the substantially rectangular film 2.
The design print layer 4 may be provided on the back surface or the front surface of the film 2 or on both the back surface and the front surface, but may be provided on the back surface of the film 2 from the viewpoint of preventing scratches. preferable. The design print layer 4 may be provided on the entire back surface or the entire surface of the film 2, but it is usually preferable that the design print layer 4 is not provided in the overlapped portion. For example, when the design print layer 4 is provided on the back surface of the film 2, the design print layer 4 is provided on the back surface of the film 2 excluding the back surface of the second side end portion 12 as shown in FIG. 1. . On the other hand, when the design print layer 4 is provided on the surface of the film 2, the design print layer 4 is provided on the surface of the film 2 excluding the surface of the first side end portion 11 (not shown).

  The design print layer 4 is a print layer on which a design such as a trade name is represented, and is composed of a known printing ink solidified layer. However, the design print layer 4 in the portion corresponding to the print layer 3 preferably has translucency so that the display of the print layer 3 can be visually recognized through the film 2. For example, the design print layer in the portion corresponding to the print layer 3 is a colorless transparent or colored transparent print layer (that is, the translucent print layer). Or the part corresponding to the display of the printing layer 3 is made into the design printing blank area | region 43 which does not provide the design printing layer 4 (refer FIG. 3). Of course, the design print layer 4 may be provided to such an extent that the visual recognition of the display of the print layer 3 is not hindered (not shown).

A desired print layer 3 is provided on the back surface of the first side end portion 11 of the film 2. The print layer 3 is a print layer on which a display regarding desired information is displayed. The desired information preferably includes secret information. Furthermore, the desired information may include information other than secret information as necessary.
Examples of the secret information include sweepstakes application information such as campaign application numbers, and spear information such as atari or lose. Examples of the information other than the secret information include traceability information such as a manufacturing code and a manufacturing date, a description, company information, and the like.

The printing layer 3 may be provided on the entire back surface of the first side end portion 11 of the film 2 (that is, the printing layer 3 is the back surface of the first side end portion 11, and It may be provided in a belt-like region including the first side edge 11a along the direction and extending in the vertical direction from the upper edge to the lower edge of the film 2). Alternatively, the print layer 3 may be provided on a part of the back surface of the first side end portion 11 of the film 2.
The part of the back surface of the first side end portion 11 is in the back surface of the first side end portion 11 of the film 2, and the upper portion, the lower portion or the middle portion in the longitudinal direction, or the first side of the film 2. A band-like shape in the back surface of the end portion 11 that is slightly separated from the first side end edge 11a in the lateral direction and narrower than the first side end portion 11 extending in the vertical direction from the upper edge to the lower edge of the film 2 One of the areas is applicable.

  In the illustrated example, the printing layer 3 is in the back surface of the first side end portion 11 of the film 2, slightly separated from the first side end edge 11 a in the lateral direction, and from the upper edge to the lower edge of the film 2. It is provided in a strip-like region that extends in the vertical direction and is narrower than the first side end portion 11. In this case, the horizontal width of the printing layer 3 is, for example, 1/2 times to 9/10 times the horizontal width of the first side end portion 11.

  The display represented on the print layer 3 is printed by a conventionally known printing method. Examples of the printing method include known gravure printing, flexographic printing, and printing using a non-impact printer. Examples of the non-impact printer include an ink jet printer, a laser beam printer, and an electrostatic recording printer. In particular, it is preferable to print using an ink jet printer. The ink jet printer includes a non-contact printing type printer in which ink flies in the air.

A first concealment layer 51 that can conceal the display of the print layer 3 is provided on the back surface of the print layer 3. That the display of the print layer 3 can be concealed means that the display of the print layer 3 can be concealed when a human views the back surface of the first concealment layer 51.
The first concealment layer 51 may be provided so as to conceal the display of the print layer 3. Therefore, the first hiding layer 51 is provided on at least the back surface corresponding to the display of the print layer 3 among the back surfaces of the print layer 3. As an example provided in this way, when the first hiding layer 51 is provided on the entire back surface of the printing layer 3, the first hiding layer 51 extends beyond the back surface of the printing layer 3 and the back surface of the printing layer 3. For example, when the first concealing layer 51 is provided on the back surface of the display so as to substantially match the display shown on the print layer 3, the case is provided.

  In the illustrated example, the first hiding layer 51 is provided so as to cover the entire back surface of the print layer 3. Accordingly, the first concealing layer 51 is laminated on the back surface of the print layer 3, and the plan view shape thereof is substantially the same as the plan view shape of the print layer 3.

The 1st concealment layer 51 consists of one layer or the multilayer printing layer which printed colored ink, such as silver or black, in solid shape, for example. The 1st concealment layer 51 is printed by methods, such as gravure printing, flexographic printing, and silk printing.
The first concealing layer 51 is preferably relatively thick. For example, when the first concealing layer 51 is formed by gravure printing, the thickness is preferably about 1 to 5 μm. When the first concealing layer 51 is formed by flexographic printing or silk printing, the thickness is 1 to 5 μm. About 100 μm is preferable.
By providing the first concealing layer 51, it is possible to reliably prevent the display shown on the print layer 3 from being visually recognized from the back surface of the cylindrical label forming substrate 1.

A second concealing layer 52 capable of concealing the display of the print layer 3 is provided on at least the surface corresponding to the print layer 3 of the surface of the first side end portion 11 of the film 2. The fact that the display of the print layer 3 can be concealed means that the display of the print layer 3 can be concealed when the surface of the second concealment layer 52 is viewed by a human.
The second concealment layer 52 may be provided so as to conceal the display of the print layer 3. Therefore, the second hiding layer 52 is provided on at least the surface corresponding to the display of the print layer 3 among the surfaces of the first side end portion 11. As an example of providing in this way, when the second hiding layer 52 is provided on the surface of the first side end 11 corresponding to the printing layer 3, the second hiding layer 52 corresponds to the printing layer 3 on the first side. When provided on the surface of the film 2 beyond the surface of the end portion 11 and the surface of the first side end portion 11, the second concealment layer 52 is substantially aligned with the display shown on the print layer 3. When it is provided on the surface of the first side end portion 11, etc.

  In the illustrated example, the second hiding layer 52 is provided so as to cover the entire surface of the first side end portion 11 corresponding to the print layer 3. In other words, the second hiding layer 52 is provided on the surface of the first side end portion 11 corresponding to the first hiding layer 51. Therefore, in the illustrated example, the planar view shape of the second hiding layer 52 is substantially the same as the planar view shape of the print layer 3.

The 2nd concealment layer 52 consists of one layer or the multilayer printing layer which printed colored ink, such as silver or black, in solid shape, for example. Similar to the first concealment layer 51, the second concealment layer 52 is printed by a method such as gravure printing, flexographic printing, or silk printing.
The second masking layer 52 is preferably relatively thick. For example, when the second concealing layer 52 is formed by gravure printing, the thickness is preferably about 1 to 5 μm. When the second concealing layer 52 is formed by flexographic printing or silk printing, the thickness is 1 to 5 μm. About 100 μm is preferable.
By providing the second concealing layer 52, it is possible to reliably prevent the display shown on the print layer 3 from being visually recognized from the surface of the cylindrical label forming substrate 1.
In order to reliably conceal the display of the print layer 3, it is preferable that the first cover layer 51 and the second cover layer 52 have the same area as the print layer 3 or an area larger than the area of the print layer 3.

  Furthermore, in order to make the 2nd concealment layer 52 adhere weakly with respect to the surface of the 1st side edge part 11, the surface of the 1st side end part 11 in the area | region in which the 2nd concealment layer 52 is provided is a 2nd concealment layer. Before providing 52, the easy peeling layer 6 is provided previously. As described above, since the easy-peeling layer 6 is interposed between the second concealing layer 52 and the first side end portion 11, the back surface of the second concealing layer 52 and the surface of the first side end portion 11 are arranged. The interlayer adhesive force is smaller than the interlayer adhesive force between the surface of the second concealing layer 52 and the back surface of the second side end portion 12. When the cylindrical label forming base material 1 on which the easily peelable layer 6 is interposed is used as a cylindrical label, as described later, when the second side end portion 12 of the cylindrical label is peeled off, the first The second concealing layer 52 and the first side end 11 can be reliably separated from each other without part of the second concealing layer 52 remaining on the surface of the side end 11.

The easy release layer 6 can be formed by a known easy release treatment, and examples of the easy release layer 6 include a cured resin layer containing a silicone resin.
The easy release layer 6 is a transparent layer. This transparency means translucency that allows the display of the print layer 3 to be visually recognized through the film 2 and the easily peelable layer 6, and may be colorless and transparent, or may be colored and transparent, like the transparent film described above. Good.

  In addition, the interlayer adhesive force between the back surface of the second concealing layer 52 and the surface of the first side end portion 11 can be reduced by appropriately designing the forming material of the second concealing layer 52. The 2nd concealment layer 52 which becomes smaller than the interlayer adhesive force with the back surface of the edge part 12 can also be comprised. Therefore, when the 2nd concealment layer 52 is provided using such a forming material, the said easy peeling layer 6 does not necessarily need to be provided.

[First Embodiment of Cylindrical Label]
The said 1st cylindrical label formation base material 1 can comprise the cylindrical label 10 by making the back surface inside as shown in FIG.4 and FIG.5.
Specifically, an adhesive, a pressure-sensitive adhesive, or a solvent (hereinafter referred to as an adhesive) is applied to at least one of the front surface side of the first side end portion 11 and the back surface of the second side end portion 12 of the substrate 1 for forming a cylindrical label. In some cases, the adhesive or solvent may be referred to as “adhesive” or the like, and the cylindrical label-forming substrate 1 is rolled into a cylindrical shape, and the second side end is formed on the surface side of the first side end portion 11. The cylindrical label 10 is obtained by superimposing the back surface of the part 12 and adhering all or part of the overlapped part via the adhesive or the like. The solvent can be used when the film or each layer is made of a material that can be solvent-bonded.

  As described above, the second hiding layer 52 is provided on the whole or a part of the surface of the first side end portion 11 of the film 2. When the second hiding layer 52 is provided on the entire surface of the first side end portion 11, the surface side of the first side end portion 11 to which the adhesive or the like is applied is the surface of the second hiding layer 52. In the case where the second concealing layer 52 is provided on a part of the surface of the first side end portion 11, the surface side of the first side end portion 11 is the surface of the second concealing layer 52 and This corresponds to the exposed portion of the surface of the first side end portion 11 where the second concealing layer 52 is not provided.

FIG. 4 shows a wound cylindrical label 10 formed by winding the cylindrical label forming substrate 1 around the adherend 9. FIG. 5 is an enlarged cross-sectional view of the overlapping portion of the cylindrical label 10.
In the case of the wound cylindrical label 10, an adhesive or a pressure-sensitive adhesive is usually applied to at least the back surface of the first side end portion 11 among the back surface of the cylindrical label forming base material 1, and becomes a winding start point. After affixing the back surface of the 1st side edge part 11 to a to-be-adhered body, and winding the base material 1 for cylindrical label formation around the to-be-adhered body, as above-mentioned, on the surface side of the 1st side edge part 11 The back surface of the second side end portion 12 is overlapped, and all or a part of the overlapped portion is bonded through an adhesive 7 or the like.

  Note that all of the overlapping portions may be bonded, or a part thereof may be bonded. When a part of the overlapped portion is bonded, the overlapped portion in the band-like region that is narrower than the width of the overlapped portion and extends in the vertical direction from the upper edge to the lower edge of the film 2 is bonded. For example, the overlapping portion in the belt-like region between the position slightly separated in the lateral direction from the first side edge 11a and the second side edge 12a is bonded.

The adhesive or the like 7 is used to bond the surface of the second hiding layer 52 and the back surface of the second side end portion 12 of the film 2 and the surface of the first side end portion 11 and the second side end portion of the film 2. This is for directly bonding the back surface of 12.
The adhesive 7 or the like that satisfies the following adhesive strength between layers is used.
Interlayer adhesive force between the back surface of the second masking layer 52 and the surface of the first side end portion 11 <Interlayer adhesive force between the surface of the second masking layer 52 and the back surface of the second side end portion 12.
Interlayer adhesive force between the back surface of the second shielding layer 52 and the surface of the first side end portion 11 <interlayer adhesive force between the surface of the first side end portion 11 and the back surface of the second side end portion 12.
However, when the easily peelable layer 6 is provided, the interlayer adhesion between the back surface of the second concealing layer 52 and the surface of the first side end portion 11 is, strictly speaking, the second concealing layer 52. This corresponds to the interlayer adhesive force between the back surface and the easy peeling layer 6 provided on the surface of the first side end portion 11.

  The interlayer adhesive force between the surface of the second masking layer 52 and the back surface of the second side end portion 12 and the interlayer adhesive force between the surface of the first side end portion 11 and the back surface of the second side end portion 12 are as follows: The interlayer adhesive force between the back surface of the second concealing layer 52 and the surface of the first side end portion 11 may be larger than the interlayer adhesive force between the surface of the second concealing layer 52 and the back surface of the second side end portion 12, and The magnitude relationship of the interlayer adhesive force between the surface of the first side end portion 11 and the back surface of the second side end portion 12 is not limited. That is, the interlayer adhesive force between the surface of the second masking layer 52 and the back surface of the second side end portion 12 and the interlayer adhesive force between the surface of the first side end portion 11 and the back surface of the second side end portion 12 are: The same or either one may be large.

In order to configure the cylindrical label 10 so that the overlapping portion is not carelessly folded during storage / conveyance, the interlayer adhesive force between the surface of the first side end portion 11 and the back surface of the second side end portion 12 is reduced. It is preferable that it is larger than the interlayer adhesive force between the surface of the second hiding layer 52 and the back surface of the second side end portion 12.
The interlayer adhesive force between the surface of the first side end portion 11 and the back surface of the second side end portion 12 is such that it cannot be inadvertently peeled off and can be peeled off by human power.

When the cylindrical label 10 is a heat-shrinkable cylindrical label or a self-expandable cylindrical label, these cylindrical labels are further used by being attached to an adherend. In the case of the wound cylindrical label 10 as shown in FIG. 4, since it is attached to the adherend 9, it is used as it is.
Examples of the adherend 9 include containers such as beverage containers, food containers, cosmetic containers, and chemical containers, packaging cases that store desired items, and cans such as spray cans.

The cylindrical label 10 is provided with a first hiding layer 51 and a second hiding layer 52 on the front side and the back side of the printing layer 3. For this reason, no one can visually recognize the display on the print layer 3 from the front side and the back side of the cylindrical label 10.
If such a cylindrical label 10 is used, for example, when a display related to secret information is displayed on the print layer 3, it is possible to prevent a third party other than the authorized purchaser from knowing the secret information.

Since the cylindrical label 10 has the second concealing layer 52 interposed, the first side end portion 11 and the second side end portion 12 are bonded and the interlayer adhesive force is in the above relationship. When the second side end portion 12 is peeled off from the first side end portion 11, the second shielding layer 52 is peeled off from the surface of the first side end portion 11 together with the second side end portion 12. When the second hiding layer 52 is peeled off from the surface of the first side end portion 11, the display of the print layer 3 can be visually recognized through the first side end portion 11 of the film 2. Thus, the cylindrical label 10 of this invention can visually recognize the display of the printing layer 3 only by opening operation.
Therefore, in order to open (remove) the attached cylindrical label 10, the authorized purchaser simply peels off the second side end 12 to display the print layer 3 hidden by the second concealment layer 52. It becomes visible from the surface of the first side end portion 11.

Furthermore, when forming the cylindrical label 10 using the said cylindrical label formation base material 1, it is more preferable to do as follows.
Specifically, as shown in FIG. 5, when the back surface of the second side end portion 12 is bonded to the surface side of the first side end portion 11, the second side end edge 12 a is formed on the second concealing layer 52. One side edge 52a (of the pair of side edges along the longitudinal direction of the second hiding layer 52, the side of the second hiding layer 52 located on the side opposite to the first side edge 11a of the film 2 in the lateral direction) It is preferable that the back surface of the second side end portion 12 is bonded to the front surface side of the first side end portion 11 in a state of extending from the end edge 52a).
If bonded in this way, the second side end 12a between the second side end edge 12a of the second side end portion 12 and one side end edge 52a of the second concealing layer 52 is interposed via an adhesive 7 or the like. The back surface of the portion 12 and the surface of the first side end portion 11 are directly bonded.

  The back surface of the second side end portion 12 and the surface of the first side end portion 11 between the second side end edge 12a of the second side end portion 12 and one side end edge 52a of the second shielding layer 52 are directly connected. The cylindrical label 10 obtained by bonding to the first side end portion 11 and the second side end portion 12 is bonded to the directly bonded portion with the second concealing layer 52 interposed therebetween. It adheres stronger than the part. This is because the portion where the first side end portion 11 and the second side end portion 12 are bonded with the second shielding layer 52 interposed therebetween is the back surface of the second shielding layer 52 and the surface of the first side end portion 11. This is because it is relatively easy to peel off.

  The directly bonded cylindrical label 10 has a second side edge 12a which is an outer edge of the overlapping portion and the vicinity thereof are strongly bonded to the surface of the first side end 11, so that the second side The end 12 can be prevented from being inadvertently peeled off from the second side edge 12a. On the other hand, when the directly adhered portion is peeled off, the second concealing layer 52 can be peeled off from the surface of the first side end portion 11 together with the second side end portion 12.
