Description

  The present invention relates to a labeled container that can be used as a container for body soap.

BACKGROUND ART Conventionally, products in which various storage items such as shampoos and beverages are put in a container are widely distributed. In order to give consideration to elderly people and people with disabilities in Japan, for packaging including such containers (for example, distinction of stored items, opening method, etc. is easy to understand), as a matter of consideration when designing packaging, The Japanese Industrial Standard (JIS S 0021) was established in 2000, and the international standard (ISO 11156) was established in 2011. Furthermore, in recent years, revision of the JIS standard has been discussed in consideration of market trends and the like (Non-Patent Document 1).
In this revision, it has been added that the body of the container for containing the body soap is formed with a vertically extending protrusion extending in the longitudinal direction of the container. Specifically, before this revision, it has been carried out to form horizontally long protrusions in a multi-stage shape at predetermined intervals in the longitudinal direction of the container on the body of the container for storing the shampoo. And, in order to distinguish the body soap from the shampoo and the rinse in consideration of the increasing tendency of use of the body soap in recent years, the container of the container for containing the body soap (hereinafter referred to as a container for body soap) It is added by JIS revision to form the vertically long projection which extends in the vertical direction. In addition, in the body of the container for storing the shampoo (hereinafter referred to as a container for shampoo), horizontally long protrusions are formed in a multistage shape with a predetermined interval in the longitudinal direction, and the container for containing rinse (hereinafter referred to as a container for rinse No protrusion is formed on the body part.

In view of these points, distribution of body soap containers having vertically long protrusions on the body is desired, but existing body soap container manufacturing molds manufacture containers that do not have vertically long protrusions. Since it is a thing, it is necessary to produce a metal mold | die newly according to the said revision.
However, mold fabrication is relatively expensive, leading to increased manufacturing costs for the container. Furthermore, in recent years, where the product life cycle is short and multi-product small-scale production has become mainstream, containers for each type of body soap are required, and all these body soap container molds are renewed. This is difficult in terms of cost.
Patent Document 1 discloses a heat-shrinkable cylindrical shape made of a heat-shrinkable synthetic resin film in which shampoo containers and rinsing containers are provided with through-holes of a predetermined shape serving as markers for finger touching in columns at predetermined intervals. It is disclosed to attach a label.
However, since containers such as shampoos and body soaps are used around water, if a heat-shrinkable film is provided with a through hole as in Patent Document 1, a relatively large amount of water can be removed from the through hole through the container and heat. It enters between the shrinkable cylindrical labels, and mold is likely to occur.
Furthermore, in the method of providing the through hole, it can not be formed in the longitudinally extending longitudinally extending projection required for the container for body soap.

Japanese Patent Application Laid-Open No. 7-329977

  An object of the present invention is to provide a labeled container in which a vertically long protrusion or a plurality of horizontally long protrusions are formed by a heat-shrinkable cylindrical label.

The labeled container according to the present invention is a cylindrical body which is heat-shrinkable in the circumferential direction, and the heat-shrinkable film is formed into a cylindrical shape, and the first side end and the second side end of the heat-shrinkable film are It has a cylindrical body having a longitudinally extending seal portion formed by bonding at least a part of the overlapped portions, and extends in the longitudinal direction of the cylindrical body on the inner surface of the cylindrical body excluding the seal portion A heat-shrinkable cylindrical label provided with a band-shaped substrate is heat-shrink mounted on the body of the container, and the first side end is a thick film part that is twice or more the thickness of the heat-shrinkable film. The outer surface of the thick film portion is formed with a laterally elongated convex portion and a laterally elongated concave portion extending in the circumferential direction alternately in the longitudinal direction, and a ridge on the outer surface of the cylindrical body corresponding to the band-shaped substrate. Is formed.
When such a container with a label is externally seen , a plurality of horizontal protrusions formed on the outer surface of the thick film portion and a plurality of horizontal protrusions resulting from the horizontally elongated recesses, and a protrusion caused by the belt-like substrate can be visually recognized. If you hold the attached container by hand, you will be able to detect the ridges with your finger. As described above, the labeled container of the present invention has the same ridges as those of the protrusions even when the container having no longitudinally long protrusion or a plurality of laterally long protrusions is used.

Preferred labeled container of the present invention, prior Symbol strip-like base material is provided at a position opposed to the seal portion.
Since the strip base material and the seal portion face each other, a ridge due to the strip base material can be formed on one side surface of the container, and a side projection strip resulting from the seal portion facing the side opposite to the side surface Can be formed.

In a preferred labeled container according to the present invention, the belt-like substrate is made of a resin material laminated on the inner surface of the heat-shrinkable film by melt extrusion.
Such a belt-like substrate can be easily provided at a desired position of the cylindrical body.

  In a preferred labeled container according to the present invention, the band-shaped substrate has heat shrinkability in the circumferential direction of the cylindrical body. Since the thickness of the band-like base material is increased due to heat contraction, the height of protrusion of the ridges on the outer surface of the cylindrical body is large, so that it is easy to visually recognize, and it is easy to determine finger touch.

  In a preferred labeled container of the present invention, the belt-like substrate is provided from the upper edge to the lower edge of the cylindrical body. A heat-shrinkable cylindrical label in which a belt-like base material is provided from the upper edge to the lower edge of the cylindrical body is easy to manufacture.

In a preferred labeled container according to the present invention, a plurality of long protrusions extending in the circumferential direction of the cylindrical body are formed on one surface of the belt-like substrate with a space in the vertical direction, and correspond to the long protrusions. By forming protrusions on the outer surface of the cylindrical body, the lateral ridges are formed in multiple stages in the vertical direction on the outer surface of the cylindrical body corresponding to the band-shaped substrate.
Such a container with a label can be suitably used as a shampoo container, since the horizontal protrusions similar to the JIS standard horizontal protrusions are formed in multiple stages on the outer surface of the cylindrical body.

  Even when the container with a label of the present invention uses a container that does not have a vertically long protrusion or a plurality of horizontally long protrusions, protrusions are formed on the outer surface of the heat-shrinkable cylindrical label. Such a labeled container can be used, for example, as a body soap container or a shampoo container conforming to JIS standards, and can be manufactured at a relatively low cost.

First Embodiment
The labeled container of the present invention has a heat-shrinkable cylindrical label and a container, and the heat-shrinkable cylindrical label is heat-shrinkably attached to the body of the container.
This heat-shrinkable cylindrical label has a cylindrical body which is heat-shrinkable in the circumferential direction in which a heat-shrinkable film is formed into a cylindrical shape, and a strip-shaped base extending in the longitudinal direction of the cylindrical body on the inner surface of the cylindrical body. A material is provided, and a ridge is formed on the outer surface of the cylindrical body corresponding to the belt-like base material in a state of being mounted on the container.
The heat-shrinkable cylindrical label and the container will be described below, and then the labeled container will be described.

<Heat shrinkable cylindrical label>
FIGS. 1 and 2 are views of the heat-shrinkable cylindrical label 1 opened in a cylindrical shape, and FIGS. 3 to 6 are views of the heat-shrinkable cylindrical label 1 folded in a flat shape. is there.
The heat-shrinkable cylindrical label 1 is usually obtained by cutting a cylindrical long body as described later, but the cylindrical long body is flat at the time of cutting.
As shown in FIG. 3 and FIG. 4, the heat-shrinkable cylindrical label 1 folded into a flat shape is opened in a cylindrical shape as shown in FIG. 1 when mounted on a container.

In FIGS. 1 to 6, the heat-shrinkable cylindrical label 1 has a cylindrical body in which the heat-shrinkable film 2 is formed in a cylindrical shape. This cylindrical body has a seal portion 23 formed by overlapping the first side end portion 21 and the second side end portion 22 of the heat-shrinkable film 2 and bonding at least a part of the overlapped portion. The seal portion 23 extends in the longitudinal direction of the cylindrical body. Note that the longitudinal direction of the cylindrical body is a direction parallel to the cylindrical axial direction.
In the present invention, a strip-like base material 7 extending in the longitudinal direction of the cylindrical body is provided on the inner surface of the cylindrical body.
In this specification, heat shrinkability refers to a property of shrinking when heated to a required temperature (for example, 70 ° C. to 100 ° C.).

The heat-shrinkable film 2 is a film having a substantially rectangular shape in plan view.
The heat-shrinkable film 2 is, for example, a film which can be greatly shrunk in the lateral direction (in the lateral direction, when it is a cylindrical body, the circumferential direction. The same applies hereinafter). The heat-shrinkable film 2 may be slightly shrunk or thermally expanded in the longitudinal direction (the longitudinal direction is a direction perpendicular to the transverse direction in the plane of the film). Examples of the heat shrinkable film 2 include polyester resins such as polyethylene terephthalate and polylactic acid; polyolefin resins such as polypropylene and cyclic olefin resin; polystyrene resins such as polystyrene and styrene-butadiene copolymer; polyvinyl chloride The synthetic resin film which consists of 1 type, or 2 or more types of mixtures etc. chosen from thermoplastic resins, such as system resin, can be used. It is preferable to use a film containing a polyester-based resin as the heat-shrinkable film 2 because it has a large shrinkage stress and a relatively strong stiffness, and it is more preferable to use a film containing a polyethylene terephthalate-based resin. The heat-shrinkable film 2 may be one having heat-shrinkability and self-stretchability. The self-stretching property refers to a property that stretches when pulled at room temperature and restores to its original state when the tensile force is released.

The heat-shrinkable film 2 may be composed of a single-layer film (monolayer film), or may be composed of a film (laminated film) in which two or more layers are integrally laminated. When the heat shrinkable film 2 is a laminated film, each layer of the laminated film can be selected arbitrarily. As the laminated film, a laminated film in which two or more kinds of film layers having heat shrinkability are laminated, a laminated film in which a transparent gas barrier layer is laminated on a film layer having heat shrinkability, and the like can be used. When the heat-shrinkable film 2 is a laminated film, the material of each film layer may be substantially the same or different. The single-layer film is preferably a film containing a polyester resin (preferably, a polyethylene terephthalate resin), and the laminated film has at least one layer containing a polyester resin (preferably a polyethylene terephthalate resin). preferable.
Although the thickness of the heat-shrinkable film 2 is not particularly limited, it is, for example, 20 μm to 120 μm, preferably 30 μm to 80 μm.

The heat-shrinkable film 2 is mainly thermally shrunk in the lateral direction (the main thermal shrinkage direction is the lateral direction).
The heat shrinkage rate in the transverse direction of the heat-shrinkable film 2 is, for example, 20% or more, preferably 30% or more, more preferably 40% or more. When the heat-shrinkable film 2 is a film which thermally shrinks or thermally expands slightly in the longitudinal direction, the thermal shrinkage rate in the longitudinal direction is preferably -3% to 15%.
However, the heat shrinkage ratio is the ratio of the length of the film before heating (original length) and the length of the film after immersion in warm water of 90 ° C. for 10 seconds (length after immersion) It is obtained by substituting into the following formula.
Said thermal contraction rate (%) = [{(original length in horizontal or vertical direction)-(length after immersion in horizontal or vertical direction)} / (original length in horizontal or vertical direction) ] × 100.
Moreover, although the said heat-shrinkable film 2 may be non-transparent, when providing a printing layer in the inner surface side, what was excellent in transparency is used. The transparency index of the transparent (colorless transparent or colored transparent) heat-shrinkable film 2 is a total light transmittance of 70% or more, preferably 80% or more, more preferably 90% or more. However, the total light transmittance is measured by a measuring method based on JIS K7105 (plastic optical property test method).

A printed layer (not shown) representing the design is provided on at least one of the inner surface and the outer surface of the heat-shrinkable film 2 as necessary. The print layer is preferably provided on the inner surface of the heat-shrinkable film 2.
Although the thickness of a printing layer is not specifically limited, For example, they are 0.1 micrometer-5 micrometers, Preferably, they are 0.2 micrometer-3 micrometers.
Moreover, functional layers (not shown) other than a printing layer may be provided in the heat-shrinkable film 2 as needed. Examples of the functional layer include a protective layer for protecting the surface of the printing layer, a sliding layer for improving the slipperiness of the inner surface of the heat-shrinkable cylindrical label 1, and an adhesive layer for adhering to the outer surface of the container. .

The tubular body is formed by laminating the first side end 21 and the second side end 22 of the heat-shrinkable film 2 and bonding at least a part of the overlapped portion to form the seal portion 23. It is formed in a cylindrical shape. For example, as shown in FIG. 5A, the inner surface of the first side end 21 and the outer surface of the second side end 22 are superimposed (or the outer surface of the first side end 21 and the second side end 22 The seal portion 23 is formed by bonding the inner surface and bonding at least a part of the overlapping portion. The seal portion 23 is a thick portion in the cylindrical body because the film is a double-layered portion.
The first side end 21 of the heat shrinkable film 2 is one side end of the two longitudinally extending side ends, and the second side end 22 of the heat shrinkable film 2 is the other side. Side edge of the The first side end 21 and the second side end 22 face each other in the lateral direction.
In addition, about the formation method of the seal | sticker part 23, it replaces with the structure of Fig.5 (a), and as shown to the figure (b), the inner surface of the 1st side edge part 21 and the inner surface of the 2nd side edge part 22 overlap. The seal portion 23 may be formed by joining (or overlapping the outer surface of the first side end 21 and the outer surface of the second side end 22) and bonding at least a part of the overlapped portion.

The strip-shaped substrate 7 is provided on the inner surface of the cylindrical body.
The belt-like substrate 7 is not particularly limited, and examples thereof include paper, synthetic paper, synthetic resin film, foamed resin film, metal vapor deposition film, and laminated sheets thereof. As the belt-like substrate 7, a substrate having heat shrinkability may be used, or a substrate having substantially no heat shrinkability (non-heat shrinkable substrate) may be used.
For example, the belt-like substrate 7 is a substrate having heat shrinkability. As a kind of base material which has heat-shrinkability, the synthetic resin film which was illustrated as the said heat-shrinkable film 2, or a laminated film containing the same is mentioned.
Like the heat-shrinkable film 2, the heat-shrinkable band-like substrate 7 mainly shrinks in one direction, does not shrink substantially in the direction perpendicular to the main heat-shrinkage direction, or slightly Shrink or heat stretch. The main heat shrink direction of the belt-like substrate 7 is the lateral direction). The main heat shrink direction of the strip-shaped substrate 7 is the short direction. In addition, the strip | belt-shaped base material 7 is provided in the inner surface of a cylindrical body by making the short direction (main heat contraction direction) of the strip | belt-shaped base material 7 into the circumferential direction of a cylindrical body.
The thermal contraction rate in the short direction of the strip-like substrate 7 is, for example, 20% or more, preferably 30% or more, and more preferably 40% or more. Moreover, when the strip | belt-shaped base material 7 heat-shrinks or thermally expands a little in the longitudinal direction, the thermal contraction rate in the longitudinal direction is preferably -3%-15%.
The heat-shrinkable band-like base material 7 may be the same as or different from the heat-shrinkable film 2, but preferably has a heat-shrinkable property that describes the same contraction curve as the heat-shrinkable film 2. It is preferable to have. For example, the same film as the heat-shrinkable film 2 is used as the belt-like substrate 7 having heat-shrinkability.

  Moreover, as the strip | belt-shaped base material 7, you may be comprised from the base material by which the unfoamed resin layer was laminated | stacked on one side or both surfaces. Examples thereof include those in which an unfoamed resin layer is laminated on one side or both sides of a base material such as paper, synthetic paper, heat-shrinkable or non-heat-shrinkable synthetic resin film. The unfoamed resin layer is preferably a heat-foamable resin layer that foams at the heating temperature of the heat-shrinkable cylindrical label 1. The non-foamed resin layer can be formed using a known foamed ink or the like. The thickness of the non-foamed resin layer is not particularly limited, and is, for example, 1 μm to 10 μm. The foamability of the unfoamed resin layer is not particularly limited, and examples thereof include an unfoamed resin that can be foamed 5 to 20 times. The belt-like base material 7 having the non-foamed resin layer has a relatively small thickness before the heat-shrinkable cylindrical label 1 is attached to the container, and is foamed by heating when the heat-shrinkable cylindrical label 1 is attached to the container As a result, the heat-shrinkable cylindrical label 1 having such a strip-like base material 7 can give a vertical protrusion to the container that is more easily discernable through visual or tactile sense.

The width of the band-shaped substrate 7 is not particularly limited, but if it is too large or small, the width of the vertical protrusion similar to the vertically long protrusion described later becomes too large or too small, and the band-shaped substrate 7 is not heated. In the case of a shrinkable substrate, if the width of the belt-like substrate 7 is too large, the heat shrinkage inhibition of the heat shrinkable film 2 constituting the heat shrinkable cylindrical label 1 becomes large. From such a viewpoint, the width of the belt-like substrate 7 is preferably 1 mm to 10 mm, more preferably 2 mm to 8 mm, and still more preferably 3 mm to 6 mm. The width of the thick film portion 3 is the length of the strip-like base material 7 in the circumferential direction of the cylindrical body.
The thickness of the band-shaped substrate 7 is not particularly limited, but if it is too small, the height of the vertical protrusion similar to the vertically long protrusion described later becomes too small, and if too large, the production of the heat-shrinkable cylindrical label 1; Handling properties during storage and when mounting the container on the container are deteriorated. From such a viewpoint, the thickness of the belt-like substrate 7 is preferably 100 μm to 500 μm, more preferably 150 μm to 400 μm, and still more preferably 200 μm to 350 μm.

The strip-like base material 7 is provided from the upper edge 1a to the lower edge 1b of the cylindrical body, with the longitudinal direction as the longitudinal direction of the cylindrical body.
The band-like base material 7 is attached to the inner surface of the cylindrical body with such an adhesive strength that the part or the whole does not come off from the cylindrical body at the time of heat contraction of the heat-shrinkable cylindrical label 1.
As a method of applying the strip-shaped substrate 7 to the tubular body, the strip-shaped substrate 7 is stuck to the inner surface of the tubular body using an adhesive layer (or adhesive layer), or the strip-shaped substrate 7 is heat-shrinkable. When the film 2 is made of a material that can be solvent-bonded, the belt-shaped substrate 7 is bonded to the inner surface of the cylindrical body using a solvent, or the belt-shaped substrate 7 is bonded to the inner surface of the cylindrical body using ultrasonic waves. The method of adhering is mentioned.
In the example of illustration, the strip | belt-shaped base material 7 is stuck on the inner surface of a cylindrical body via the adhesive layer 71 (or adhesive layer) (refer FIG. 7). The thickness of the pressure-sensitive adhesive layer 71 is not particularly limited, and is, for example, 5 μm to 30 μm, preferably 10 μm to 25 μm.
The arrangement of the belt-like base material 7 is not particularly limited, and may be provided at any position in the circumferential direction of the cylindrical body. Preferably, the strip-like base material 7 is provided at a position facing the seal portion 23.

The heat-shrinkable cylindrical label 1 of the present invention can be produced, for example, by the following method.
As shown in FIG. 7, the raw fabric 4 is pulled out from a roll of a long heat-shrinkable film (hereinafter referred to as raw fabric 4), and the strip-shaped substrate 7 is pulled out from a roll of a long strip-shaped substrate 7. The belt-like substrate 7 is pasted on the inner surface of the raw fabric 4 in the longitudinal direction. When using the elongate strip shaped base material 7 in which the adhesive layer is previously provided, the strip | belt-shaped base material 7 pulled out from the roll is stuck on the raw fabric 4 via the adhesive layer. When using the elongate strip-shaped base material 7 in which the adhesive layer is not provided, after pulling out the strip-shaped base material 7 from a roll, it is applied to one side of the strip-shaped base material 7 and / or a predetermined portion of the raw fabric 4. An adhesive or the like is applied and the belt-like substrate 7 is pasted. Or when using the elongate strip | belt-shaped base material 7 in which the adhesive layer is not provided, after using the original fabric 4 which apply | coated the hot-melt-adhesive in the predetermined location, and pulling out the original fabric 4 from a roll The hot melt adhesive may be heated and melted, and the strip-like substrate 7 may be attached to the adhesive.
Then, the outer surface of the second side end portion 22 of the raw fabric 4 and the inner surface of the first side end portion 21 are overlapped and adhered to obtain the cylindrical elongated body 41. The said cylindrical elongate body 41 is like a precursor of a cylindrical label, Comprising: The several heat-shrinkable cylindrical label 1 is connected continuously in concept. The long shape is a rectangular shape in which the length in the longitudinal direction is sufficiently larger than the length in the lateral direction, for example, the length in the longitudinal direction is 10 times or more of the length in the lateral direction, preferably 50 times or more.
By cutting the tubular long body 41 into a predetermined length, the heat-shrinkable tubular label 1 of the present invention as shown in FIGS. 1 to 6 is obtained.
In addition, although solvent adhesion is illustrated as an adhesion method of the 1st side edge part 21 and the 2nd side edge part 22 of the said raw fabric 4, it is not limited to this, When using the adhesion method by an adhesive agent, it is a solvent. Instead of applying an adhesive, or using an ultrasonic bonding method, without applying a solvent, the outer surface of the second side end portion 22 and the inner surface of the first side end portion 21 of the original fabric 4 are applied. After superposition, ultrasonic waves are applied to a required portion of the superposition portion to pressurize.

Moreover, it replaces with the method of affixing the said elongate strip shaped base material to a raw fabric, and may laminate | stack a strip shaped base material by laminating | stacking a resin material on the required location of raw material by melt extrusion.
Specifically, the raw material is drawn from the roll, and laminated in the longitudinal direction with a predetermined width (for example, substantially the same as the width of the belt-like substrate 7) while extruding the molten hot melt resin onto the inner surface of the raw material. To do. The hot melt resin is solidified after being laminated, whereby a base material (that is, a band-like base material) extending in a band shape with a predetermined width is formed on the inner surface of the raw fabric. The thickness of the resin to be laminated is preferably the same as the thickness of the belt-like substrate 7. After that, a cylindrical elongated body can be obtained by overlapping and adhering the first side end portion and the second side end portion of the original fabric in the same manner as in the method for producing the heat-shrinkable cylindrical label. The manufacturing method of the heat-shrinkable cylindrical label was a method in which a base material (a long belt-like base material 7) formed in advance in a strip shape was attached to the original fabric. By conceptually laminating the resin material, which is the raw material, on the raw material by melt extrusion, it can be said that it is conceptually a method in which the formation of the belt-like substrate and the application of the belt-like substrate to the raw material are simultaneously performed on the raw material. Such a heat-shrinkable cylindrical label is composed of a resin material in which a belt-like substrate 7 is laminated on the inner surface of a heat-shrinkable film by melt extrusion.
Thus, according to the method of laminating resin materials, it is possible to easily form a partial band-like base material. According to this method, as in [Fifth Embodiment] described later, the heat-shrinkable cylindrical label 1 (in other words, the cylindrical body) in which the belt-like base material 7 is provided in the middle in the longitudinal direction of the cylindrical body. The heat-shrinkable cylindrical label 1) provided with the strip-like base material 7 can be easily formed except for the upper and lower regions of the above. In this case, a heat-shrinkable cylindrical label 1 is obtained in which a band-like base material made of a resin material laminated on the inner surface of the heat-shrinkable film by melt extrusion is provided in the longitudinal direction of the cylindrical body.

<Container>
Each of the containers has a body portion having a storage portion inside and a pouring portion.
Specifically, as shown in FIG. 8 and FIG. 9, the container 9 is a surface where the first side surface 91 and the second side surface 92 of the trunk portion do not have unevenness. In addition, the surface having no unevenness means a surface having no unevenness such as a vertically long protrusion or a horizontally long protrusion according to JIS standards. Therefore, the side surface of the body may be an uneven curved surface or the like for the function and design of a general container.
The pouring part 99 of the container 9 is made of, for example, a body soap that can be pumped by a pump structure, but is not limited to such a pouring part 99, and the pouring part made of an opening is closed with a cap. It may be a structure.

<Container with label>
As shown in FIGS. 8 and 9, the heat-shrinkable cylindrical label 1 is externally fitted to the body portion of the container 9 so that the seal portion 23 is positioned on the first side surface 91 of the body portion of the container 9. In the heat-shrinkable cylindrical label 1, the belt-like base material 7 is disposed so as to face the seal portion 23. Therefore, when the seal portion 23 is aligned with the first side surface 91 of the container 9, the belt-like base material 7 becomes the container. It comes to be located in the 2nd side 92 (the 2nd side is the side opposite to the 1st side) of the trunk of nine.
After the outer fitting, the heat-shrinkable cylindrical label 1 (heat-shrinkable film 2) is shrunk in the circumferential direction by heating the heat-shrinkable cylindrical label 1 to a required temperature, corresponding to the first side surface 91 A labeled container 10 is obtained in which the heat-shrinkable cylindrical label 1 is in close contact with the trunk of the container 9 in a state where the seal portion 23 is disposed and the belt-like substrate 7 is disposed corresponding to the second side surface 92 ( 10 and 11).

In the labeled container 10, since the heat-shrinkable cylindrical label 1 is thermally shrunk in the circumferential direction, the inner surface of the seal portion 23 and the peripheral region thereof is in close contact with the outer surface of the first side surface 91 of the trunk portion, The inner surface of the band-like base material 7 and the peripheral area thereof is in close contact with the outer surface of the second side surface 92 of the body. Since the inner surface of the belt-like substrate 7 is strongly pressed against the second side surface 92 by the shrinkage force of the heat-shrinkable film 2, a cylindrical body corresponding to the belt-like substrate 7 (heat-shrinkable tubular label 1). As shown in FIG. 11, a protrusion is formed on the outer surface.
Since the strip-like base material 7 is extended in the longitudinal direction of the cylindrical body, the outer surface of the heat-shrinkable tubular label 1 after being attached to the container 9 is in the longitudinal direction due to the strip-like base material 7 A ridge (longitudinal ridge) is formed extending in the direction.

As described above, the side surface 91, 92 of the body portion of the container 9 is not formed with a vertically long protrusion, but the heat-shrinkable cylindrical label 1 of the present invention is attached to the container 9 by heat-shrinking to form a belt-like shape. The outer surface of the cylindrical body (heat-shrinkable film 2) corresponding to the substrate 7 protrudes by approximately the thickness of the strip-shaped substrate 7. Therefore, when the labeled container 10 is externally seen, it appears that a vertically long protrusion is formed on the second side surface 92 of the body of the container 9, and when the labeled container 10 is held by hand, It becomes possible to discriminate the vertical ridge caused by the material 7 with a finger. Thus, if the heat-shrinkable cylindrical label 1 of this invention is used, the vertical protrusion similar to a vertical protrusion can be provided to the container 9 in which the vertical protrusion is not formed.
In particular, by using the heat-shrinkable belt-like base material 7, the heat-shrinkable film 2 and the belt-like base material 7 are thermally shrunk in the width direction (the circumferential direction of the cylindrical body) by heating. The thickness of the base material 7 becomes larger than that before heating. However, since the belt-like substrate 7 is bonded to the inner surface of the heat-shrinkable film 2, the heat-shrinkage rate of the belt-like substrate 7 is slightly lower than that in the free state, but the heat-shrinkable belt-like substrate The material 7 causes an increase in wall thickness. Due to the increase in thickness of the strip-shaped substrate 7, the protrusion height of the ridges on the outer surface of the cylindrical body (heat-shrinkable film 2) corresponding to the strip-shaped substrate 7 becomes larger, and it is easier to distinguish through visual or tactile sense A labeled container 10 having vertical ridges can be configured.
The labeled container of the present invention conforms to the JIS standard by attaching the heat-shrinkable cylindrical label 1 to an existing container having no vertically long protrusion.
Further, since the seal portion 23 extending in the longitudinal direction is a portion where the film is doubled, if the seal portion 23 is also touched with a finger, it can be determined as a vertical ridge. For this reason, for example, if the heat-shrinkable cylindrical label 1 in which the above-described belt-like base material 7 and the seal portion 23 are arranged to face each other is used, both side surfaces 91 of the container 9 in which no vertically long protrusion is formed, At 92, a labeled container 10 is obtained in which longitudinal ridges similar to the longitudinal projections are formed.

That is, the folded film portion 31 is non-adhesively stacked on the to-be-folded film portion 32. The thick film portion 3 is configured by the folded film portion 31 and the to-be-folded film portion 32. In other words, the thick film part 3 is comprised from the part (henceforth a double film part) where the part of the heat-shrinkable film 2 overlapped twice. The thickness of the thick film portion 3 in which the film portion is doubled is twice or more the thickness of the heat-shrinkable film 2.

The second first surface is the same surface.
The width of the folded film portion 31 is not particularly limited, but if it is too large or small, the width of the vertical ridge similar to the vertically long protrusion described later becomes too large or too small. From such a viewpoint, the width of the folded film portion 31 is preferably 3 mm to 15 mm, more preferably 3 mm to 10 mm, and still more preferably 4 mm to 8 mm. Note that the width of the thick film portion 3 is equal to the width of the folded film portion 31. The widths of the folded film portion 31 and the thick film portion 3 are the lengths in the lateral direction of the folded film portion 31 and the thick film portion 3. The lengths of the folded film portion 31 and the thick film portion 3 are equal to the length of the heat shrinkable film 2 in the longitudinal direction.

The four edges of the heat-shrinkable film 2 having a substantially rectangular shape in a plan view, in which the folded film portion 31 is not formed, are all composed of the edge (cutting edge) of the heat-shrinkable film 2 itself. As described above, four edges of the heat-shrinkable film 2 having a substantially rectangular shape in a plan view, in which the folded film portion 31 is formed, of which three are composed of the edges of the heat-shrinkable film 2 itself, 1 side edge 2a) is composed of a crease A. The first side end 21 refers to a portion of a required width including the folded film portion 31 from the first side edge 2 a.

Further, the second side end 22 refers to a portion having a required width from the second side edge 2 b of the heat shrinkable film 2. The width of the second side end 22 is not particularly limited, and is, for example, 3 mm to 25 mm, preferably 5 mm to 15 mm.
The width of the first side end 21 refers to the lateral length from the first side edge 2a, and the width of the second side end 22 refers to the lateral length from the second side edge 2b. .

As shown by the arrow in FIG. 16, the heat-shrinkable film 2 on which the folded film portion 31 is formed is rolled into a cylindrical shape such that the first surface is on the inside, and the first side end having the folded film portion 31 The cylindrical body is obtained by laminating the inner surface of the portion 21 on the outer surface of the second side end 22 and bonding at least a part of the overlapped portion. Of the overlapped portions, the portion where the side end portions are joined is the seal portion 23.
Specifically, as shown in FIGS. 12, 14, and 15, a part of the first side end 21 and the second side among the portions where the first side end 21 and the second side end 22 are overlapped. A seal portion 23 is formed by bonding a part of the end portion 22. The seal portion 23 extends in the longitudinal direction from the upper edge 1a of the cylindrical body to the lower edge 1b.

The first side end portion 21 is not entirely bonded to the second side end portion 22, and part of the second surface of the thick film portion 3 and the thick film portion 3 of the first side end portion 21. And the first surface of the single-layer film portion 211 adjacent to the second side end portion 22 is bonded to the second surface of the second side end 22. In the cylindrical state, the second surface of the folded film portion 31 and the first surface of the single layer film portion 211 become the inner surface of the first side end portion 21, and the second surface of the second side end portion 22. Is the outer surface of the second side end 22.
About the thick film part 3, the part (tip part of the folded film part 31) of required width | variety is adhere | attached on the 2nd side edge part 22 from the front-end edge 31a of the folded film part 31, and the thick film part 3 Among the first side edge 2 a (fold A), a portion having a required width is not bonded to the second side end 22 and is a surplus piece B. In other words, the first side end 21 is bonded to the second side end 22 except for a part of the thick film portion 3.
The portion (remaining piece B) of the thick film portion 3 which is not adhered to the second side end portion 22 extends in the longitudinal direction along the seal portion 23.
The width of the excess piece B which is a part of the thick film portion 3 is not particularly limited, and is, for example, 2 mm to 10 mm, preferably 2 mm to 5 mm. The width of the excess piece B refers to the length of the excess piece B in the circumferential direction of the cylindrical body.

Further, the folded film portion 31 is not bonded to the inner surface (first surface) of the folded film portion 32, and the leading end portion including the leading edge 31a of the folded film portion 31 and the single film portion 211 are respectively second. Bonded to the side end 22. The folded film portion 31 and the to-be-folded film portion 32 are integrated through a part of the second side end portion 22. The integrated folded film portion 31 and the to-be-folded film portion 32 (thick film portion 3) form a tubular extending in the longitudinal direction (the tubular is when the cylindrical body is viewed from above (FIG. 3) The same is true for the cross-sectional view of FIG. In addition, this tubular shape means a shape having a closed space inside, and when the heat-shrinkable tubular label 1 is folded in a flat shape, the thick film portion 3 is also a flat tubular shape. .
In FIG. 15, the closed space inside the thick film portion 3 is greatly opened, and the thick film portion 3 does not appear to be a flat tube, but this is the folded film portion 31 constituting the thick film portion 3. Is intended to represent the non-adhesion to the film-to-be-folded portion 32 in an easy-to-understand manner. Please keep in mind.

The second side end 22 is not entirely bonded to the first side end 21, except for a portion (remaining margin C) of the second side end 22 having a predetermined width from the second side edge 2 b. The first side end 21 is bonded.
The bonding method of the first side end portion 21 and the second side end portion 22 is not particularly limited, and when the heat-shrinkable film 2 is made of a material that can be bonded with a solvent, bonding using a solvent or an adhesive is used. Bonding, ultrasonic bonding and the like. In the illustrated example, a part of the first side end 21 and a part of the second side end 22 are bonded using a solvent.
The width of the seal portion 23 is not particularly limited, and is, for example, 2 mm to 12 mm, preferably 3 mm to 10 mm.

The heat-shrinkable cylindrical label 1 of the present embodiment can be manufactured, for example, by the following method.
As shown in FIG. 17, the original fabric 4 is pulled out from the roll, and the strip-shaped substrate 7 is pulled out from the roll of the elongated strip-shaped substrate 7 to the inner surface of the original fabric 4, and is elongated to the inner surface of the original fabric 4. Paste in the direction.
Next, one side portion extending in the longitudinal direction of the raw fabric 4 is folded inward at the fold line A to form a folded film portion 31. Next, a solvent is applied to a required portion of the outer surface of the second side end 22 of the folded raw fabric 4 and / or the inner surface of the first side end 21 including the folded film portion 31 (the solvent applying step is Not shown). Then, by overlapping and bonding the outer surface of the second side end portion 22 of the raw fabric 4 and the inner surface of the first side end portion 21 including the folded film portion 31, a cylindrical elongated body 41 is obtained. By cutting this cylindrical elongated body 41 into a predetermined length, the heat-shrinkable tubular label 1 of the second embodiment as shown in FIGS. 12 to 15 is obtained.

As shown in FIG. 18, the heat-shrinkable cylindrical label 1 is externally fitted to the body portion of the container 9 so that the thick film portion 3 is positioned on the first side surface 91 of the body portion of the container 9. Since the heat-shrinkable cylindrical label 1 is disposed so that the strip-shaped base material 7 faces the seal portion 23, when the seal portion 23 is aligned with the first side surface 91 of the container 9, the strip-shaped base material 7 9 is located on the second side surface 92 of the trunk portion.
After the outer fitting, the heat-shrinkable cylindrical label 1 (heat-shrinkable film 2) is shrunk in the circumferential direction by heating the heat-shrinkable cylindrical label 1 to a required temperature, corresponding to the first side surface 91 A labeled container 10 is obtained in which the heat-shrinkable cylindrical label 1 is in close contact with the body of the container 9 in a state where the thick film portion 3 is disposed and the belt-like substrate 7 is disposed corresponding to the second side surface 92. (See FIGS. 19 and 20).
In the labeled container 10, since the heat-shrinkable cylindrical label 1 is thermally shrunk in the circumferential direction, the inner surface of the seal portion 23 and the peripheral region thereof is in close contact with the outer surface of the first side surface 91 of the trunk portion, The inner surface of the band-like base material 7 and the peripheral area thereof is in close contact with the outer surface of the second side surface 92 of the body.
On the outer surface of the heat-shrinkable cylindrical label 1, a ridge (vertical ridge) extending in the vertical direction is formed due to the band-shaped substrate 7, as in the first embodiment.

In addition, since the heat-shrinkable cylindrical label 1 of the present embodiment has the thick film portion 3 (the integrated folded film portion 31 and the to-be-folded film portion 32), the heat-shrinkable cylindrical label 1 is provided on the outer surface thereof. A ridge (longitudinal ridge) extending in the longitudinal direction due to the thick film portion 3 is formed.
As described above, if the heat-shrinkable cylindrical label 1 having the thick film portion 3 and the strip-like base material 7 and the seal portion 23 (thick film portion 3) are disposed to face each other, longitudinally long A labeled container 10 is obtained in which vertical ridges similar to the vertically long protrusions are formed on both side surfaces 91 and 92 of the container 9 where no part is formed.

In particular, when the thick film portion 3 is composed of a part of the heat-shrinkable film 2, heating increases the thickness of the thick film portion 3 and improves the three-dimensionality. A protrusion that can be more easily discriminated can be formed on the first side surface 91 of the container 9.
That is, since the thick film portion 3 which is a part of the heat-shrinkable film 2 and is formed into a tubular shape is also thermally shrunk when heated, as shown in FIG. 20, the thick film folded into a flat tubular shape. The portion 3 protrudes in a state of being bulging outward (in other words, as the cross-sectional shape of the tubular closed space changes into an elliptical shape, the thickness itself of the thick film portion 3 also increases).

Specifically, the part of the required width from the leading edge 31a of the folded film part 31 is bonded to the second side end part 22, but the required width of the folded film part 31 from the first side edge 2a (fold A). This non-adhered part is freely deformable since the part and the whole of the film-to-be-folded part 32 are not adhered to the second side end 22. For this reason, since the whole of the non-adhered portion contracts by heating and deforms so as to approach a circular shape, the thick film portion 3 protrudes in a swelled outward direction of the cylindrical body. Furthermore, when the thick film portion 3 is thermally shrunk, its thickness naturally also increases. As described above, since the portion of the folded film portion 31 having the required width from the leading edge 31a is bonded to the second side end portion 22, the thick film portion 3 swelled in the radially outward direction is the seal portion 23. Never be too far away.
In addition, since the thickness of the thick film part 3 becomes large after heating and a three-dimensional shape change occurs in which the thick film part 3 swells radially outward, the width of the thick film part 3 after heating is a flat tubular shape. It becomes smaller than the width of the thick film portion 3 before heating. In the case of the heat-shrinkable film 2 having the above-mentioned heat-shrinkage ratio, the width of the thick-film portion 3 after heating is flat tube heating although the heat-shrinkage ratio in the transverse direction of the heat-shrinkable film 2 is affected. It changes to about 0.3 to 0.6 times the width of the previous thick film part 3, and the protruding height of the thick film part 3 after heating is that of the thick film part 3 before heating in the shape of a flat tube. The height changes about 1.5 to 3 times the height (the height of the thick film portion 3 before heating is equal to the thickness of the thick film portion 3).

  As described above, when the thick film portion 3 is formed of the heat shrinkable film 2 and the thick film portion 3 is formed in a tubular shape, the thick film portion 3 is heated after heating as described above. Since it swells outward in the radial direction, it is possible to form a vertical ridge that can be more easily discriminated visually or tactilely in the container.

Third Embodiment
The third embodiment relates to the heat-shrinkable cylindrical label 1 in which the thick film portion shown in the second embodiment is marked.
Specifically, as shown in FIG. 21, the thick film portion 3 is provided with a mark layer 8. This mark layer 8 is a layer that exhibits an appearance different from the printed layer of the design applied to the heat shrinkable film 2. Examples of the mark layer 8 include a printing layer made of an ink containing a sparkling component such as a pearl pigment, a printing layer made of an ink exhibiting a fluorescent color, and a hologram layer exhibiting a hologram-like appearance.
The mark layer 8 is preferably provided so as to be visible over the entire width of the thick film portion 3. For example, by providing the mark layer 8 at least on the folded film portion 31 (from the leading edge 31a of the folded film portion 31 to the fold A), the mark layer 8 can be viewed over the entire width of the folded film portion 31. In the illustrated example, the mark layer 8 is provided straddling the turnaround film portion 31 and a part of the turnaround film portion 32.
The mark layer 8 may be provided on the outer surface, but is preferably provided on the inner surface as in the illustrated example in order to prevent scratches.
By providing the mark layer 8 in the thick film portion 3 as in the present embodiment, the thick film portion 3 becomes conspicuous, and the user has a thickness that is the same vertical protrusion as the vertically long protrusion. The presence of the meat film portion 3 can be easily discriminated visually.

Fourth Embodiment
The fourth embodiment is various modifications of the thick film portion of the second embodiment.
In the said 2nd Embodiment, although the thick film part 3 is comprised from the double film part, it is not limited to this, You may be comprised from the part which the film overlapped more than triple. For example, as shown in FIG. 22, the thick film portion 3 is folded back into two folded film portions 311 and 312 and a folded film by turning the side of the heat-shrinkable film 2 twice inward so as to draw a vortex. You may be comprised from the triple film part which consists of the part 32. FIG.
In this case, the second folded film portion 312 inserted between the first folded film portion 311 and the to-be-folded film portion 32 may be both the first folded film portion 311 and the to-be-folded film portion 32 or the first folded film. The second side end 22 is made non-adhered (not adhered) to one of the part 311 or the folded film part 32 and at least a part of the first folded film part 311 is adhered to the second side end 22. The unfolded film portion 31 and the to-be-folded film portion 32 can be integrated and formed into a tubular shape (the tubular thick film portion 3 can be configured).
In the illustrated example, only the tip end portion of the first folded film portion 311 of the thick film portion 3 is adhered to the second side end portion 22.
Even when the end portion of the second folded film portion 312 is bonded to the folded film portion 32 instead of bonding the first folded film portion 311 to the second side end portion 22, the tubular thick film portion 3 can be configured.

In addition, when the thick film portion 3 is configured from a portion where the films overlap three or more times, in the example of FIG. 22, the side portion of the heat shrinkable film 2 is folded back so as to draw a swirl. For example, as shown in FIG. 23, the thick film portion 3 may be covered with two folded film portions 313 and 314 by folding the side of the heat-shrinkable film 2 twice in a zigzag manner. You may be comprised from the triple film part which consists of the return | turnback film part 32. FIG.
In this case, the second folded film portion 314 inserted between the first folded film portion 313 and the to-be-folded film portion 32 may be both the first folded film portion 313 and the to-be-folded film portion 32 or the first folded film. The second side end 22 is made non-adhered (not bonded) to one of the part 313 or the folded film part 32 and at least a part of the first folded film part 313 is adhered to the second side end 22. The unfolded film portion 31 and the to-be-folded film portion 32 can be integrated and formed into a tubular shape (the tubular thick film portion 3 can be configured). In this case, two seal portions 23 that are separated from each other in the circumferential direction of the cylindrical body are formed in the overlapping portion of the first side end portion 21 and the second side end portion 22.
In FIG. 22 and FIG. 23, the thick film portion 3 is not shown in particular because it can be formed in the same manner as in FIG. 22 and FIG.

Moreover, in the said embodiment, although the thick film part 3 is formed in a tubular shape, it is not limited to this, For example, as shown in FIG. 24, the 1st surface of the return film part 31 and the to-be-folded film part 32 The folded film portion 31 and the to-be-folded film portion 32 may be directly integrated by bonding the whole facing the first surface of the film (two or more double-layered thick film portions 3 are integrated) It may be composed of a film part). In this case, the folded film portion 31 is bonded to the entirety of the to-be-folded film portion 32 and a part of the second side end portion 22.
Such thick film portion 3 can also be thermally shrunk in the width direction (circumferential direction of the heat-shrinkable cylindrical label 1) by heating, so the thickness of the thick film portion 3 after heating is greater than before heating Also grows. However, when two or more film portions are bonded to each other, the heat shrinkage rate is slightly lowered, and the thick film portion 3 formed in a tubular shape as in the above embodiment is heated. The thick film portion 3 is preferably tubular because it causes a three-dimensional shape change in the radially outward direction.

  Furthermore, in the above embodiment, the end including the end edge 31a of the folded film portion 31 is bonded to the second side end 22. For example, as shown in FIG. 25, the outer end of the folded film portion 31 May be bonded to the second side end portion 22. Even in this case, the folded film part 31 and the folded film part 32 are integrated via the second side end part 22 and formed into a tubular shape. In addition, at the overlapping portion of the first side end portion 21 and the second side end portion 22, two seal portions 23 that are separated in the circumferential direction of the cylindrical body are formed.

Furthermore, in the above-described embodiment, in the seal portion 23, the first side end 21 is bonded to the second side end 22 except for a part of the thick film portion 3 (the thick film portion 3 Part is bonded to the second side end 22 and part of the thick film portion 3 is not bonded to the second side end 22). For example, as shown in FIG. 26, the first side end 21 The whole of the thick film portion 3 may be adhered to the second side end 22 except for the above. In this case, in order to form a tubular shape, the folded film portion 31 and the folded film portion are bonded by partially adhering the tip 31b of the folded film portion 31 to the first surface of the folded film portion 32 as shown in the figure. 32 are directly integrated while forming a tubular (formation of a tubular thick film portion 3).
Thus, even when the entire thick film portion 3 is not bonded to the second side end portion 22, the tubular thick film portion 3 is deformed so as to contract and expand outward by heating. . However, as in the first embodiment, when the portion of the required width from the leading edge 31a of the folded film portion 31 is bonded to the second side end portion 22 and the thick film portion 3 is formed in a tubular shape, the diameter Since the thick film portion 3 expanded outward is not separated from the seal portion 23 too much, it is preferable that the user's finger hardly catches on the thick film portion 3 when using the labeled container 10.

Further, in the above embodiment, in the seal portion 23, a part of the thick film portion 3 is not adhered to the second side end portion 22. For example, as shown in FIG. All may be bonded to the second side end 22.
In this case, the folded film portion 31 and the to-be-folded film portion 32 may be entirely bonded as shown in FIG. 24, or may be partially bonded, or may not be entirely bonded. . When the folded film part 31 and the folded film part 32 are partially bonded or non-bonded entirely, the tubular thick film part 3 is configured.

Furthermore, in the said embodiment, although the thick film part 3 is provided only in the 1st side edge part 21, as shown in FIG. 28, the thick film part 3 is provided also in the 2nd side edge part 22. As shown in FIG. It may be
Moreover, in the said embodiment, although the 1st side edge part 21 is accumulated on the outer surface of the 2nd side edge part 22 (that is, in the seal part 23, the 1st side edge part 21 arrange | positions on the outer side of a cylindrical body). However, the present invention is not limited to this. For example, as shown in FIG. 29, the second side end 22 is superimposed on the outer surface of the first side end 21 provided with the thick film portion 3, The seal portion 23 may be formed by bonding at least a part of the overlapping portion.
In the above-mentioned embodiment, although a part of superposition part of the 1st side end 21 and the 2nd side end 22 is pasted up, all the superposition parts may be pasted up.

Fifth Embodiment
In the heat-shrinkable cylindrical label 1 in each of the above-described embodiments, the band-like base material 7 is provided from the upper edge 1a to the lower edge 1b of the cylindrical body, but is not limited thereto. Thus, the strip-like base material 7 may be provided in the longitudinal direction in the longitudinal direction midway portion of the cylindrical body. The strip-shaped substrate 7 is preferably provided with a length of 5 cm or more in the longitudinal direction of the tubular body, although it depends on the longitudinal length of the tubular body. Therefore, the strip-shaped substrate 7 shown in FIG. The length between the upper edge 7a and the upper edge 1a of the cylindrical body and the length between the lower edge 7b of the belt-like base material 7 and the lower edge 1b of the cylindrical body can be appropriately set in consideration of this.
In addition, when sticking a long strip-shaped base material to a long heat-shrinkable film (raw fabric) to form a tubular long body (heat-shrinkable tubular label), it is easy to The belt-like base material 7 is preferably provided from the upper edge 1a to the lower edge 1b of the cylindrical body because it can be manufactured.

Sixth Embodiment
The sixth embodiment relates to a heat-shrinkable cylindrical label in which the lateral ridges are formed in a multi-tiered manner at predetermined intervals.
As described above, the heat-shrinkable cylindrical label 1 of each of the above-described embodiments is a longitudinal protrusion conforming to the JIS standard by providing the strip-like base material 7 (the thick film portion 3 as needed) extending in the longitudinal direction. The labeled container which has the same vertical protrusion as a part can be comprised.
For example, by using the strip-like base material 7 having irregularities formed on one surface (or both surfaces), it is possible to construct a labeled container having a plurality of horizontal protrusions similar to the plurality of laterally long protrusions which are JIS standards of a shampoo container. .
As shown in FIGS. 31 and 32, in the belt-like base material 7 used in the present embodiment, the long convex portion 61 extending in the short direction and the long concave portion 62 extending in the short direction extend in the longitudinal direction It is alternately formed. As described above, when the belt-like substrate 7 is provided in the cylindrical body, the short direction of the belt-like substrate 7 corresponds to the circumferential direction of the cylindrical body, and the longitudinal direction of the belt-like substrate 7 is cylindrical It corresponds to the vertical direction of the body. In FIG. 31, a thick line represents a long concave portion 62, and a white portion between the thick lines is a long convex portion 61. Although not particularly illustrated, the elongated concave portion and the elongated convex portion may be formed on both sides of the belt-like substrate 7.

The depth D62 of the elongated recess 62 is not particularly limited, and is, for example, 0.2 mm to 1 mm, preferably 0.3 mm to 0.5 mm. In the present embodiment, a strip-like base material 7 having a thickness capable of forming such a long concave portion 62 having such a depth is used.
The longitudinal length L 62 of the elongated recess 62 is not particularly limited, and is, for example, 3 mm to 10 mm, preferably 4 mm to 6 mm. The longitudinal length L 61 of the elongated convex portion 61 is not particularly limited, and is, for example, 1 mm to 8 mm, preferably 1 mm to 5 mm.
As shown in FIG. 32, the depth D62 of the long concave portion 62 is a length between the bottom of the long concave portion 62 and the top of the long convex portion 61, and the longitudinal length of the long concave portion 62 is long. L 62 is the length between the end portions of the adjacent long convex portions 61, and the longitudinal length L 61 of the long convex portion 61 is the length between both end portions of one long convex portion 61.
The belt-like base material 7 having the long concave portions 62 and the long convex portions 61 is formed by, for example, embossing or cutting one surface of the base material, and attaching a convex resin to one surface of the base material. It can obtain by methods, such as using the base material by which the field was formed into stripe unevenness.

As shown in FIG. 33, the heat-shrinkable cylindrical label 1 of the present embodiment can be obtained by sticking the belt-like base material 7 having such irregularities to the inner surface of the heat-shrinkable film 2 and forming it into a cylindrical shape. can get.
As shown in FIG. 33, it is preferable that the belt-like base material 7 be pasted with its asperity-formed surface facing the inner surface side of the heat-shrinkable film 2. As a result, a space 69 extending in the circumferential direction of the cylindrical body is generated between the elongated concave portion 62 of the belt-like base material 7 and the inner surface of the heat-shrinkable film 2. When contracted, a relatively large dent (in other words, a relatively large convex) is generated on the outer surface of the cylindrical body.
The bonding method of the belt-like substrate 7 to the heat-shrinkable film 2 is not particularly limited, and the method exemplified in the above embodiment can be used, but in the illustrated example, the long convex portions 61 of the belt-like substrate 7 Is adhered to the inner surface of the heat shrinkable film 2 through the adhesive layer 73.

The labeled container using the heat-shrinkable cylindrical label 1 of the present embodiment is used, for example, as a container for shampoo.
The heat-shrinkable cylindrical label 1 is fitted on the body of the container so that the belt-like base material 7 of the heat-shrinkable tubular label 1 is located on the side of the body of the container, and then heated. A labeled container 10 as shown at 34 is obtained.
Since the elongated concave portion 62 is formed in the strip-like base material 7, as shown in FIG. 35, the heat shrinkable film 2 is greatly expanded into the elongated concave portion 62 of the strip-like base material 7 (that is, the space 69). As shown in FIGS. 34 and 35, the outer surface of the heat-shrinkable film 2 (cylindrical body) is shrunk, and a circumferentially extending recess 1c is formed. That is, in the outer surface of the heat-shrinkable label 1 corresponding to the elongated concave portions 62 of the strip-shaped base material 7, recesses 1c extending in the longitudinal direction at intervals in the longitudinal direction are formed in multiple stages and adjacent in the longitudinal direction A convex 1d is formed between the concaves 1c. By forming the recesses 1c and the projections 1d, the outer surface of the heat-shrinkable cylindrical label 1 is formed with a plurality of lateral ridges extending in the circumferential direction between the adjacent recesses 1c in the vertical direction. The The labeled container 10 of the present embodiment has horizontal ridges similar to the plurality of laterally long protrusions of the JIS standard, and thus can be suitably used as a container for shampoo.

Seventh Embodiment
Further, as in the sixth embodiment, the thick film portion 3 shown in the second embodiment and the like is further subjected to a concavo-convex process, so that the plurality of laterally elongated protrusions according to the JIS standard of the shampoo container are obtained. A labeled container 1 having a horizontal ridge can be provided.
In particular, the thick film portion 3 is provided facing the belt-like substrate 7 of the heat-shrinkable cylindrical label 1 provided with the uneven belt-like substrate 7 described in the sixth embodiment, and the thick film. By subjecting the portion 3 to the concavo-convex processing of the present embodiment, it is possible to obtain a labeled container having lateral ridges similar to the laterally long protrusions on both side surfaces of the container.

Specifically, in FIGS. 36 to 38, in the heat-shrinkable cylindrical label 1 of the present embodiment, the first side end 21 is twice the thickness of the heat-shrinkable film 2 as in the above embodiment. It has the above thick film part 3. This thick film part 3 consists of a double or more film part.
On the outer surface of the thick film portion 3, a laterally long convex portion 81 extending in the circumferential direction and a laterally long concave portion 82 extending in the circumferential direction are formed alternately and continuously in the longitudinal direction. Note that, in FIG. 36, a thick line indicates a horizontally long concave portion 82, and a white portion between the thick lines is a horizontally long convex portion 81.
The thick film portion 3 having such an uneven outer surface can be typically formed by embossing the thick film portion 3. For example, when the seal portion 23 is formed by ultrasonic bonding, embossing (for example, knurling) is performed to bond the first side end portion 21 and the second side end portion 22 (formation of the seal portion 23). At the same time, it is possible to form the laterally long convex portion 81 and the horizontally long concave portion 82 (concave and convex formation) in the thick film portion 3.
In this case, as explained in the manufacturing method of the heat-shrinkable cylindrical label 1 of the first embodiment, the second side end portion 22 and the first side end portion 21 of the raw fabric 4 on which the folded film portion 31 is formed. After superposing, a cylindrical long cylindrical body is obtained by ultrasonically bonding the superposed part while rolling the knurled embossing roll on the superposed part, and by cutting it, this embodiment The heat-shrinkable cylindrical label 1 is obtained.

The illustrated example is a case where the formation of the seal portion 23 and the formation of irregularities are performed simultaneously. In this case, a laterally elongated recess 82 is formed at least over the entire width of the thick film portion 3, and the thick film portion 3 is integrated by directly bonding the folded film portion 31 and the folded film portion 32. And is bonded to the second side end portion 22 by the seal portion 23.
After the heat-shrinkable cylindrical label 1 is externally fitted to the body of the container so that the seal part 23 of the heat-shrinkable tubular label 1 is located on the side of the body of the container, the heat shrinkage is achieved by heating. A labeled container 10 is obtained in which the sex tubular label 1 is in close contact with the body of the container.
Since the horizontally long convex portion 81 and the horizontally long concave portion 82 formed on the thick film portion 3 extend in the circumferential direction of the heat-shrinkable cylindrical label 1, the heat-shrinkable cylindrical label 1 is thermally contracted in the circumferential direction. Also, the laterally long convex portion 81 and the laterally long concave portion 82 do not disappear. For this reason, in the heat-shrinkable cylindrical label 1 after being thermally shrunk in the container, a plurality of horizontal ridges are formed in a multistage manner in the longitudinal direction according to the unevenness of the thick film portion 3. The labeled container 10 of the present embodiment has horizontal ridges similar to the plurality of laterally long protrusions of the JIS standard, and thus can be suitably used as a container for shampoo.

In addition, the labeled container of the present invention is not limited to the case of being used as a container for body soap or a container for shampoo.
In addition, one or more of the configurations described in the first to seventh embodiments can be combined, replaced, or changed as appropriate.
