When the object is viewed from the front side, both the pattern of the main display layer and the pattern of the sub display layer can be visually recognized.

The cylindrical label 1 of this invention can be divided roughly into the following two types, for example.
The first cylindrical label is a cylindrical label formed into a cylindrical shape by overlaying and bonding the inner surface of the first side end of the film to the outer surface of the second side end, and is attached to the container body. It is the cylindrical label currently formed in the cylinder shape before making it contact. The first cylindrical label is attached in close contact with the container body by opening it into a tubular shape and fitting it on the outside of the container body, and causing the film to thermally shrink or self-shrink.
The second cylindrical label is obtained by partially bonding the inner surface of the second side end portion of the film to the container body, winding the film around the container body, and forming the first side end of the film on the outer surface of the second side end portion. It is a cylindrical label formed into a cylindrical shape by bonding the inner surface of the part. This second cylindrical label is generally called a wound cylindrical label or a wound label. The second cylindrical label is closely attached to the container body in that state, or is attached to the container body by heat shrinking or self-shrinking the film.

The first cylindrical label is a label formed in a cylindrical shape before contacting the container body (a label in which the first side end and the second side end are bonded from before the container body is mounted). The second cylindrical label is a label formed in a cylindrical shape at the same time as being brought into contact with the container body (a label on which the first side end and the second side end are adhered while being in contact with the container body) ) Is different.
These cylindrical labels are different in production from the point of time when they are formed into a cylindrical shape. However, since the film and the pattern display area X, etc. constituting the cylindrical labels are the same, the following description will focus on the first cylindrical label. It shall be explained in

<Outline of cylindrical label>
The cylindrical label 1 before being closely attached to the container body can be opened in a cylindrical shape as shown in FIGS.
The cylindrical label 1 is opened in a cylindrical shape when attached to a container body, but during normal transportation and storage, as shown in FIGS. 3 to 5, a pair of fold lines 29, 29 opposed in the circumferential direction are provided. And is folded flat.
In a realistic manufacturing process, the cylindrical label 1 is provided in the form of a continuous body in which a plurality of the continuous labels are continuously connected and folded in a flat shape. By cutting this continuous body appropriately, a flat cylindrical label 1 as shown in FIGS. 3 to 5 is obtained.

Specifically, the flexible cylindrical label 1 (tubular film 2) can be opened in a cylindrical shape, but is usually folded in two at a pair of opposed folds 29, 29, and is generally flat. Has been.
The pair of folds 29, 29 are formed at locations that bisect the circumferential length of the cylindrical label 1, and extend in the axial direction. The flat cylindrical label 1 is divided into a front surface portion and a back surface portion by the two folds 29, 29. In FIG. 5, with reference to the two folds 29, 29, the lower film portion sandwiched between the two folds is the front surface portion, and the upper film portion of the paper surface is the back surface portion.

<Tubular film>
The cylindrical label 1 of the first embodiment is mainly composed of a transparent cylindrical film 2, and a pattern display region X is provided by applying a decorative process such as desired printing to the cylindrical film 2. Yes.
The tubular film 2 is formed by forming a sheet-like transparent film into a tubular shape.
The film is not particularly limited as long as it is transparent (colorless transparent or colored transparent) and has strength and flexibility, and a conventionally known thermoplastic resin film can be used.
In the present embodiment in which the colored hiding layer is provided, the tubular film 2 is preferably colorless and transparent.
As an index of translucency of a film, for example, it can be expressed using total light transmittance. The total light transmittance of the film is, for example, 70% or more, preferably 80% or more, and more preferably 90% or more. However, the total light transmittance of the film was measured under the standard condition (23 ° C., 1 atm, relative humidity 50%) with an ultraviolet-visible spectrophotometer (trade name “UV-2600 manufactured by Shimadzu Corporation). "), And the value measured in the range of wavelengths from 250 nm to 800 nm.
Although the thickness of a film is not specifically limited, For example, they are 8 micrometers-120 micrometers, and also are about 15 micrometers-100 micrometers.

The film may have at least one of heat shrinkability and self-stretchability in terms of shrinkage characteristics, or may not have them.
The heat shrinkability refers to a property of shrinking when heated to a predetermined temperature (for example, 70 ° C. to 100 ° C.). The self-stretching property refers to the property of extending in the radially outward direction by applying an expansion force, and restoring the original size by releasing the expansion force.
The tubular label 1 formed using a heat-shrinkable film (heat-shrinkable film) is generally called a heat-shrinkable tubular label, a tubular shrink or a shrink label, and has a self-stretching film. The cylindrical label 1 formed using (self-stretchable film) is generally called a self-stretchable cylindrical label or a stretch label.

The material of the film is not particularly limited. In the case of heat-shrinkable films, for example, polyester resins such as polyethylene terephthalate, olefin resins such as polypropylene and cyclic olefin, styrene resins such as styrene-butadiene copolymer, and thermoplastic resins such as vinyl chloride resin. The stretched film containing is mentioned. In the case of a self-stretchable film, for example, an olefin resin such as polyethylene, a film containing a thermoplastic resin such as ethylene vinyl acetate copolymer, and the like can be given.
Preferably, the cylindrical film 2 is formed using a heat-shrinkable film.

As the heat-shrinkable film, a film that mainly heat-shrinks in at least the first direction may be used, and a film that slightly heat-shrinks or heat-extends in the second direction may be used. The first direction means one direction in the plane of the film, and the second direction is a direction orthogonal to the first direction in the plane. As such a heat-shrinkable film, a uniaxially stretched or biaxially stretched film mainly stretched in the first direction can be used. Such a stretched film is oriented at least in the first direction, and has a property of tearing easily in the first direction (tearability).
The heat shrinkage rate in the first direction (heat shrink direction) of the heat shrinkable film is not particularly limited, but is preferably 20% or more, more preferably 30% or more, and further preferably 40% or more. is there. In addition, although the heat shrinkage rate in the said 1st direction is so preferable that it is large, since there exists a limit naturally, the heat shrinkage rate in the said 1st direction is theoretically less than 100%. When the heat-shrinkable film is a film that changes heat in the second direction, the heat shrinkage rate in the second direction is, for example, −3 to 15%, preferably 0 to 10%. The minus of the thermal contraction rate means thermal elongation.
However, the heat shrinkage ratio is the length of the film before heating (stored under standard conditions for 24 hours) (original length) and the length of the film after being immersed in 90 ° C. warm water for 10 seconds and taken out. (Length after immersion) is measured under standard conditions, and is obtained by substituting into the following formula.
Thermal contraction rate (%) = [{(original length in the first direction (or second direction)) − (length after immersion in the first direction (or second direction))} / (first direction (Or the original length in the second direction)]] × 100.

The film is rolled into a cylindrical shape so that the first direction (thermal shrinkage direction) of the heat-shrinkable film is the circumferential direction, and the first side end is overlapped and bonded to the second side end to seal the seal part. By forming 28, the tubular film 2 is configured. The seal portion 28 extends in a strip shape in the axial direction of the cylindrical label 1.
In addition, when using a self-expanding film, the cylindrical film 2 is comprised by rounding into a cylinder shape and adhere | attaching both edge parts so that the expansion-contraction direction may turn into the circumferential direction.
The bonding method between the first side end and the second side end is not particularly limited, and examples thereof include welding using a solvent and bonding using an adhesive.
The circumferential length of the tubular film 2 using the heat-shrinkable film is, for example, more than the maximum circumference x 1 times of the portion to which the container body is attached x 1 x 1.5 times, preferably x 1.01. Times to the same × 1.3 times, more preferably the same × 1.02 times to the same × 1.15 times.
The peripheral length of the tubular film 2 using the self-shrinkable film is, for example, the maximum peripheral length of the attached portion of the container body x 0.9 times to 1 time, and preferably the same x 0.92 times or more and 1 time. Is less than.

A colorless and transparent overcoat printing layer (not shown) may be provided on the inner surface side and / or outer surface side of the tubular film 2. Such an overcoat printing layer is formed by printing a conventionally known colorless transparent ink or the like by a conventionally known printing method.
Although the thickness of an overcoat printing layer is not specifically limited, For example, they are 1 micrometer-5 micrometers.

<Pattern display area and translucent area>
A pattern display area X is provided on the front surface of the tubular film 2, and a light transmitting area Y is provided on the back surface of the tubular film 2 on the opposite side in the circumferential direction with respect to the pattern display area X.

It is a layer which makes it possible to visually recognize the pattern of the sub display layer 5 under circumstances.

Here, in the present specification, the “printing layer” refers to a layer made of an ink solidified product formed from a conventionally known ink by a conventionally known printing method (gravure printing, flexographic printing, etc.). In the present specification, the printed layer is one in which the ink solidified material is present in a solid form, or one or more types of ink solidified material are present in a plan view sea island structure. Thus, one layer is formed.
The phrase “solidified ink solidified and forms one layer” means that the solidified ink extends continuously in the surface direction to form a single layer.

One or a plurality of types of ink solidified products exist in a sea-island structure in a plan view and form one layer. (A) The layer is a sea-island structure (one or more in a plan view). The island portion is surrounded by the sea portion), and one or more types of ink solidified product form the sea portion, and there is no ink solidified product on the island portion. (B) The layer has a sea-island structure (a plan view structure in which one or more island portions are surrounded by a sea portion) in plan view, and one or more types In the case where the ink solidified product forms a sea portion and the ink solidified product having a different color from the ink solidified product in the sea portion forms an island portion, (C) the layer is a sea-island structure in plan view ( One or a plurality of types of ink solidified). There forms an island portion, and, there is no ink solidified in the sea portion, if the sea portion is a void portion, and the like.
The void portion is a portion where no ink solidified product exists, but is conceptually included in the constituent elements of the print layer in the hierarchy. That is, the main display layer 3 and the sub display layer 5 are conceptually independent layers (hierarchies), and the vacant part of each hierarchy is considered as one of the components of the hierarchy.

The ink is classified into colorless transparent ink and colored transparent ink (color ink). A colored transparent printing layer can be formed by printing a colored transparent ink relatively thinly, and a substantially opaque printing layer can be formed by printing a colored transparent ink very thickly.
A colorless transparent ink is an ink substantially free of a colorant (also called a medium ink). The colorless and transparent ink contains a binder resin, and may contain a solvent and / or an additive as necessary. The color ink (colored transparent ink) contains a binder resin and a colorant, and may contain a solvent and / or an additive as necessary.

On the other hand, in the translucent area | region Y, it consists only of the cylindrical film 2 (or the cylindrical film 2 in which the transparent overcoat layer was provided). Therefore, the translucent area Y is transparent like the tubular film 2, and the translucency of the translucent area Y is the same as the translucency of the tubular film 2.
In addition, the colored transparent printing layer which represents the non-patterned colored transparent printing layer or the pattern to such an extent that the light transmission is not hindered in a part or the whole of the range of the tubular film 2 which becomes the transparent region Y. May be provided.

<Main display layer>
Referring to FIGS. 8 and 9, the main display layer 3 is a printed layer having a first part 31 and a second part 32 having different translucency, and a pattern is represented by the first part 31. . Hereinafter, the first part 31 and the second part 32 of the main display layer 3 are referred to as “main first part” and “main second part”.
In this specification, translucency means that the two total light transmittances of interest are different, or the two total light transmittances of interest are the same, but the wavelength of light that is mainly transmitted. Including different.
In the present embodiment, the main display layer 3 has the above-mentioned printing layer (A) (has a sea-island structure in plan view, and one or more kinds of solidified ink form a sea part, and the island part. Ink solidified material does not exist, and the island portion is emptied).

  Specifically, in the pattern display region X, the main second portion 32 is made of a colored and transparent ink solidified that forms the sea portion of the sea-island structure, and the main first portion 31 is made of an empty portion. Accordingly, the main first portion 31 is a portion surrounded by the edge of the main second portion 32, and is composed of an empty portion (a portion where no ink solidified product exists) in the main display layer 3. In front views such as FIGS. 1 and 3, the main first portion 31 that is a portion surrounded by the edge of the main second portion 32 is represented by a square.

The main second portion 32 can visually recognize the color when viewed from the front side. The color of the ink solidified material constituting the main second portion 32 is not particularly limited and is arbitrary. The main second portion 32 made of a colored transparent ink solidified product has translucency.
By the main second portion 32 having translucency, the light is transmitted through the main second portion 32 under the condition where high-intensity light is incident from the back side through the translucent region Y, and is viewed as viewed from the front side. The pattern of the layer 5 becomes visible.
Although the thickness of the main 2nd part 32 which consists of ink solidified materials is not specifically limited, For example, they are 1 micrometer-5 micrometers.

  On the other hand, since the main first part 31 is composed of an imaginary part, its total light transmittance is theoretically 100%. In the main first part 31 composed of the vacant part, the color of the colored hiding layer 4 (light reflected from the colored hiding layer 4) can be seen from the front side, which is represented by the main first part 31. It becomes a pattern. 1 and 3, the pattern represented by the main first portion 31 is represented by a square for convenience.

The main display layer 3 is formed by printing color ink (blue, red, etc.) on the inner surface of the pattern display region X of the tubular film 2 by a printing method except for a portion that becomes the main first portion 31. .
In the pattern display region X, the main display layer 3 may include a colored third portion having translucency different from that of the main first portion 31 and the main second portion 32 (not shown). ) The colored third portion of the main display layer 3 may represent a pattern.

<Colored hiding layer>
The colored hiding layer 4 is a solid colored transparent layer having translucency and light reflectivity.
Since the colored hiding layer 4 has light reflectivity, light incident on the pattern display region X from the front side is appropriately reflected, and the pattern of the sub display layer 5 cannot be visually recognized when viewed from the front side. The pattern represented by the first part 31 is visible.
Further, since the colored concealing layer 4 has translucency, the light is transmitted through the colored concealing layer 4 and seen from the front side under a situation where high intensity light is incident from the back side through the translucent region Y. The pattern represented by the main first part 31 of the main display layer 3 and the pattern represented by the first part 51 of the sub display layer 5 can be visually recognized.

The colored concealment layer 4 is provided in a solid shape over substantially the entire pattern display region X. The solid shape refers to a state in which the forming material continuously forms one layer in the plane direction.
Examples of the colored hiding layer 4 include a colored transparent printing layer and a colored transparent metal vapor deposition layer. Examples of the colored transparent print layer include a white print layer and a silver print layer, and examples of the metal vapor deposition layer include an aluminum vapor deposition layer. The colored hiding layer 4 may be composed of only one or two or more colored and transparent printed layers, or may be composed of only a metal vapor-deposited layer, or may be composed of a colored and transparent printed layer and a metal. You may have a vapor deposition layer. For example, the colored hiding layer 4 has at least one selected from a non-pattern white print layer, a non-pattern silver print layer, and a metal vapor deposition layer.
When the colored concealing layer 4 is composed of a printing layer, the colored concealing layer 4 having translucency and light reflectivity can be constructed by setting the type of color ink and the thickness of the ink solidified product.
When the colored concealing layer 4 is composed of a metal vapor-deposited layer, the colored concealing layer 4 having translucency and light reflectivity can be constructed by setting the thickness thereof.

In the present embodiment, since the cylindrical film 2 / main display layer 3 / colored hiding layer 4 / sub-display layer 5 are laminated in this order, the colored hiding layer 4 is composed of a colored transparent printing layer.
The colored concealment layer 4 in the illustrated example is configured by a patternless printing layer of one color, for example, a patternless white printing layer, a patternless silver printing layer, or the like.
Although the thickness of the colored hiding layer 4 which consists of a printing layer is not specifically limited, For example, they are 1 micrometer-5 micrometers. In addition, when the colored hiding layer 4 consists of a metal vapor deposition layer, the thickness is 50 to 500 mm, for example.
The colored concealment layer 4 made of a printing layer is formed by solid printing of color ink (white, silver, etc.) by a printing method so as to overlap the main display layer 3 in the pattern display region X of the tubular film 2. Is done.
When the main first portion 31 of the main display layer 3 is an empty portion, the ink solidified material constituting the colored hiding layer 4 is directly on the inner surface of the tubular film 2 in the portion that becomes the main first portion 31. 8 and 9, in order to clearly indicate the emptiness portion, the portion is represented by space (in the portion that becomes the main first portion 31, the colored hiding layer 4 and the tubular film 2 are separated from each other). Represent).

  Specifically, in the pattern display region X, the sub second portion 52 is made of an ink solidified material that forms the sea portion of the sea-island structure, and the sub first portion 51 is made of an empty portion. Accordingly, the sub first portion 51 is a portion surrounded by the edge of the sub second portion 52 and is formed of a vacant portion (a portion where no ink solidified product exists) in the sub display layer 5. In front views such as FIG. 1 and FIG. 3, the sub first portion 51 which is a portion surrounded by the edge of the sub second portion 52 is represented by a circle.

The sub second portion 52 may be an opaque solidified ink (opaque means that the total light transmittance of visible light is substantially 0%), but is preferably composed of a colored transparent ink solidified product. . The color of the ink solidified material constituting the sub second part 52 is not particularly limited and is arbitrary. In the case where the sub second portion 52 is made of a colored transparent ink solidified product, the translucency thereof is preferably the same as that of the main second portion 32. In particular, the sub second part 52 and the main second part 32 are more preferably made of a colored and transparent ink solidified product having the same color.
Although the thickness of the sub 2nd part 52 consisting of an ink solidified material is not specifically limited, For example, they are 1 micrometer-5 micrometers.

The sub first part 51 is configured so that the light transmitted through the sub first part 51, the colored hiding layer 4 and the main display layer 3 has a visible intensity.
The light incident on the sub first portion 51 from the back side is transmitted through the sub first portion 51, the colored hiding layer 4 and the main display layer 3 (main second portion 32) in this order, and is emitted to the front side. By configuring the sub first portion 51 so that the light transmitted through the sub first portion 51, the colored hiding layer 4 and the main display layer 3 can be visually recognized, the sub first portion 51 can be viewed from the back side through the translucent region Y. Under the condition where high intensity light is incident, the light is transmitted through the sub first portion 51, the colored hiding layer 4 and the main display layer 3, and the pattern represented by the sub first portion 51 is viewed from the front side. become able to. In FIGS. 1 and 3, the pattern represented by the sub-first portion 51 is represented by a circle for convenience.
Since the total light transmittance of the sub first part 51 composed of the vacant part is theoretically 100%, the portion corresponding to the sub first part 51 in the colored hiding layer 4 and the main display layer 3 is on the back side. Is transmitted with an intensity that can be visually recognized by human vision. By using the colored concealing layer 4 and the main display layer 3 as described above, the light can be visually recognized.

The total light transmittance in the sub first portion 51, the colored hiding layer 4 and the main display layer 3 is, for example, 0.1% to 60%, preferably 1% to 40% in the wavelength region of 400 nm to 800 nm. More preferably, it is 10% to 30%.
The total light transmittance is measured using a UV-visible spectrophotometer (trade name “UV-2600” manufactured by Shimadzu Corporation) under standard conditions (23 ° C., 1 atm, relative humidity 50%), A value obtained by measuring a wavelength range of 250 nm to 800 nm. The object to be measured is a film having a total light transmittance of 90% or more and a main printing layer, a colored concealing layer, and a sub-first part of a sub-printing layer laminated in this order. It is assumed that light is applied from the part side. When the sub first part is an empty part, the sub first part to be measured is actually the atmosphere.

The sub display layer 5 is a printing method in which color ink (blue, red, etc.) is printed in the pattern display region X of the tubular film 2 so as to overlap with the colored concealment layer 4 except for the sub first portion 51. Formed by printing.
In the pattern display region X, the sub display layer 5 may include a colored third portion having translucency different from that of the sub first portion 51 and the sub second portion 52 (not shown). ) The colored third part of the sub display layer 5 may represent a pattern.

<Areas other than pattern display area and translucent area>
In the tubular film 2, a pattern may be represented in a region other than the pattern display region X and the translucent region Y, or a pattern may not be represented.
In the illustrated example, the main display layer 3 and the colored concealment layer 4 are also provided in the tubular film 2 in areas other than the pattern display area X and the translucent area Y.
