Description

Container with label

Technical Field

The present invention relates to a labeled container in which a heat-shrinkable tubular label is attached to a container.

Background

Generally, a lid is attached to a mouth portion of a container body filled with food such as seasoning, beverage, pharmaceutical, cosmetic, or the like, and a heat-shrinkable tubular label is attached to a container including the lid for sealing. In use, the upper cylindrical portion of the heat-shrinkable cylindrical label is removed to expose the lid body, thereby allowing the contents to be taken out.

In recent years, containers are also known which are provided with a release mechanism so that the lid body can be relatively easily detached from the container body, in order to separate the container body and the lid body for disposal after use.

For example, patent document 1 discloses a hinge cover (lid body) for distinguishing waste: a thin weakened portion capable of breaking is formed on the outer peripheral surface, a gap portion penetrating in the vertical direction is provided in the outer cylinder, a slit groove connected to the gap portion is formed in the gap portion, and a thin connecting portion is formed on the inner peripheral surface side of the slit groove. The hinge cover is attached to the mouth of the container body and used.

Further, patent document 2 discloses a container and a lid including: a protrusion formed on an outer periphery of a mouth of the container; an inner cylinder and an intermediate cylinder formed on an intermediate cover made of synthetic resin and attached to the mouth portion, and sandwiching an upper portion of the mouth portion from inside and outside; the injection cylinder is arranged on the middle cover; a port wall formed to have an annular slit inside the barrel; a breaking member provided on the mouth wall; the screw strip is arranged on the outer side of the upper part of the middle cover; a synthetic resin-made outer cap including a top wall and a cylinder wall adhered to the middle cap; an outer cylinder integrally provided at a lower end portion of the outer cover via a weakened portion which is easily broken; an engaging portion formed on a lower inner surface of the outer tube and engaged with the protrusion in a vertical direction; a weakening line formed in the outer cylinder, for cutting the outer cylinder in the up-down direction and having a nip portion; and a screw groove formed on the inner surface of the cylinder wall, for locking the locking part relative to the protrusion while rotating, and screw-jointing with the screw strip.

In many cases, a heat-shrinkable tubular label is attached to a container having such a releasing mechanism, including a hinge cover or a cover (lid body), for sealing. The heat-shrinkable tubular label is attached to the entire container (from the lid to the container body) in accordance with the manner of attachment, and is referred to as a fully-shrinkable label, and a heat-shrinkable tubular label attached from the lid to the upper portion of the container body is referred to as a lid-sealing label.

Disclosure of Invention

When a labeled container having a heat-shrinkable tubular label attached to the inside of a lid body is used, the upper tubular portion of the heat-shrinkable tubular label is removed to expose the lid body, and the lid is opened to use the contents.

However, the lid may be removed by mistake while the labeled container is in use.

Problems to be solved by the invention

The invention provides a container with a label, which can prevent a cover body from being detached from a container body by mistake.

Means for solving the problems

The labeled container of the present invention comprises: a container having a container body including a mouth portion and a lid body for closing the mouth portion of the container body; and a heat-shrinkable tubular label including the lid body attached to at least an upper portion of the container so as to be in the inside, the lid body having an outer wall portion fitted to an outer peripheral wall of the mouth portion of the container body and a lid portion provided above the outer wall portion, the outer wall portion being provided with a release mechanism for releasing fitting of the outer wall portion to the outer peripheral wall of the mouth portion and having a release start point portion accessible from outside of the outer peripheral wall, the heat-shrinkable tubular label having an unsealing lateral assist line extending in a circumferential direction corresponding to a region from a lower end of the outer wall portion to a lower end of the lid portion.

In the labeled container of the present invention, the heat-shrinkable tubular label is formed with a vertical opening assist line extending from the horizontal opening assist line to a lower end of the heat-shrinkable tubular label.

In a preferred labeled container of the present invention, a 1 st vertical auxiliary line for opening extending in the longitudinal direction is formed in an upper cylindrical portion which is a portion of the heat-shrinkable cylindrical label above the horizontal auxiliary line for opening, a 2 nd vertical auxiliary line for opening extending in the longitudinal direction is formed in a lower cylindrical portion which is a portion of the heat-shrinkable cylindrical label below the horizontal auxiliary line for opening, and the 1 st vertical auxiliary line and the 2 nd vertical auxiliary line are arranged with a position shifted in the circumferential direction.

In a preferred labeled container of the present invention, the 1 st vertical auxiliary line is formed in a pair on the left and right sides.

ADVANTAGEOUS EFFECTS OF INVENTION

In the labeled container of the present invention, the opening transverse assist line is formed in the region from the lower end of the outer wall portion to the lower end of the lid portion, and therefore, even after the heat-shrinkable cylindrical label is cut along the opening transverse assist line and the upper cylindrical portion is removed, the lower cylindrical portion of the label is attached to the outer wall portion. Therefore, it is difficult to access the release starting point portion of the outer wall portion of the lid body, and it is possible to prevent the lid body from being detached from the container body by mistake.

Detailed Description

The present invention will be specifically described below with reference to the accompanying drawings.

The vertical direction of the container (and the labeled container) is a vertical direction in which the bottom surface of the container is placed on a horizontal plane and is self-standing. The circumferential direction of the container (and labeled container) refers to the direction about the longitudinal axis of the container. The longitudinal direction of the heat-shrinkable tubular label (and tubular film) means the direction of a straight line passing through the center of the cylinder when it is expanded into a cylindrical shape, and the circumferential direction of the heat-shrinkable tubular label (and tubular film) means the direction around the longitudinal axis of the cylinder. When the heat-shrinkable tubular label is made flat, the circumferential direction of the heat-shrinkable tubular label is the transverse direction.

The numerical range represented by "lower limit value X to upper limit value Y" means not less than lower limit value X and not more than upper limit value Y. When a plurality of the numerical ranges are described independently, an arbitrary lower limit value and an arbitrary upper limit value can be selected, and "an arbitrary lower limit value to an arbitrary upper limit value" can be set.

In fig. 1 to 3, a labeled container a of the present invention includes a container B and a heat-shrinkable tubular label C attached to the container B.

The container B has a container body 1 including a mouth portion and a lid body 2 for closing the mouth portion of the container body 1.

The lid body 2 has an outer wall portion 3 fitted to the outer peripheral wall of the mouth portion, and a lid portion 5 provided above the outer wall portion 3.

The outer wall portion 3 includes a release mechanism for releasing the fitting with respect to the outer peripheral wall of the mouth portion, and has a release start point portion accessible from the outside of the outer peripheral wall 3.

A transverse opening assisting line 8 extending in the circumferential direction is formed in the surface of the heat-shrinkable tubular label C. The heat-shrinkable tubular label C is attached to the container B so as to include the lid body 2 so that the opening cross-sectional line 8 corresponds to a region from the lower end of the outer wall portion 3 to the lower end of the lid portion 5. Hereinafter, a region of the heat-shrinkable tubular label C corresponding to a region from the lower end of the outer wall portion 3 to the lower end of the cover portion 5 is sometimes referred to as a "specific region" of the heat-shrinkable tubular label.

Hereinafter, the structures of the heat-shrinkable tubular label C and the container B will be described in detail independently, and the structure of the labeled container B will be described in detail.

[ Heat-shrinkable tubular label ]

Fig. 4 to 6 show the same heat-shrinkable tubular label, but fig. 4 shows the heat-shrinkable tubular label in a state of being expanded into a tubular shape just before being attached to a container, and fig. 5 and 6 show the heat-shrinkable tubular label in a state of being folded into a flat shape.

The heat-shrinkable tubular label C is attached to the container B by heat-shrinking itself.

As shown in fig. 4, the heat-shrinkable tubular label C before being heat-shrunk and attached to the container B can be opened cylindrically. Note that in the column of [ heat-shrinkable tubular label ], the heat-shrinkable tubular label C means a state before heat shrinkage (a state before being attached to the container B), and in the column of [ tubular labeled container ], the heat-shrinkable tubular label C means a state after heat shrinkage in addition to before heat shrinkage.

The heat-shrinkable tubular label C is opened in a tubular shape when attached to the container B, but is folded flat when being transported and stored, as shown in fig. 5 and 6.

In a practical manufacturing process, the heat-shrinkable tubular label C is provided in the form of a continuous body in which a plurality of labels are continuously connected and which is folded into a flat shape. By appropriately cutting the continuous body, a flat heat-shrinkable tubular label C as shown in fig. 5 and 6 is obtained.

In fig. 4 to 6, the heat-shrinkable tubular label C has a tubular film 7 having heat shrinkability and a transverse opening assist line 8 formed to extend in the circumferential direction at a longitudinal middle portion of the tubular film 7. Preferably, the tubular film 7 is formed with a vertical opening assisting line 9 extending in the vertical direction.

The cylindrical film 7 is obtained by forming a heat shrinkable film into a cylindrical shape.

The heat-shrinkable film is a film that shrinks in the heat-shrinking direction when heated to a heat-shrinking temperature. The heat shrinkage temperature is, for example, 60 to 120 ℃ and preferably 80 to 110 ℃.

Examples of the heat-shrinkable film include a synthetic resin film, a nonwoven fabric, a foamed resin film having heat shrinkability, and a laminate film of these materials. The laminate film may be a laminate of a layer having no heat shrinkability and a layer having heat shrinkability, provided that the laminate has heat shrinkability as a whole. Preferably, a synthetic resin film or a synthetic resin laminated film is used as the heat shrinkable film, and more preferably, a synthetic resin film or a synthetic resin laminated film not containing a fiber-containing sheet such as a nonwoven fabric (the laminated film also includes a film containing a metal-deposited synthetic resin) is used.

The synthetic resin film and the synthetic resin laminated film are not particularly limited in material, and examples thereof include polyester resins such as polyethylene terephthalate and polylactic acid; olefin resins such as polypropylene and cyclic olefins; polystyrene resins such as polystyrene and styrene-butadiene copolymers; a polyamide resin; and a mixture of 1 or 2 or more selected from thermoplastic resins such as vinyl chloride resins. The synthetic resin film having heat shrinkability may be composed of 1 resin layer, or may be composed of a plurality of resin layers of different types or the same type. Since the film is relatively flexible and is easily broken in the circumferential direction, a film including a polyester resin layer is preferably used, and a laminated film in which a polystyrene resin layer and a polyester resin layer are laminated (for example, a film having 3 laminated portions of PET/PS/PET) is more preferably used.

The heat shrinkable film may be transparent or non-transparent, but it is preferable to use a transparent heat shrinkable film.

The thickness of the heat shrinkable film is not particularly limited, but for example, a heat shrinkable film of about 8 μm to 100 μm, and further about 20 μm to 80 μm can be used.

As the heat-shrinkable film, a film that is heat-shrunk mainly in at least the 1 st direction may be used, and a film that is slightly heat-shrunk or heat-stretched in the 2 nd direction may be used. The 1 st direction refers to 1 direction in the plane of the film, and the 2 nd direction refers to a direction orthogonal to the 1 st direction in the plane. As the heat shrinkable film, a uniaxially or biaxially stretched film mainly stretched in the 1 st direction can be used. The stretched film is oriented at least in the 1 st direction and has a property of being easily broken in the 1 st direction (tearability).

The heat shrinkage rate of the heat-shrinkable film in the 1 st direction (heat shrinkage direction) is not particularly limited, but is preferably 20% or more, more preferably 30% or more, and still more preferably 40% or more. The larger the thermal shrinkage ratio in the 1 st direction is, the more preferable it is, but the thermal shrinkage ratio in the 1 st direction is theoretically less than 100% because it has a limit of its own. In the case where the heat-shrinkable film is a film thermally changed in the 2 nd direction, the heat shrinkage in the 2 nd direction is, for example, -3% to 15%, preferably 0 to 10%. The negative value of the thermal shrinkage ratio refers to thermal elongation.

The length (original length) of the film before heating (stored in a standard state (23 ℃, 1 atmosphere, 50% RH atmosphere) for 24 hours) and the length (length after immersion) of the film after being taken out by immersing in hot water at 90 ℃ for 10 seconds were measured in a standard state, and the thermal shrinkage ratio was obtained by substituting the following equation. In addition, the length of each film was measured in a standard state.

The heat shrinkage ratio (%) is [ { (original length in the 1 st direction (or 2 nd direction)) }/(original length in the 1 st direction (or 2 nd direction)) × 100.

The heat-shrinkable film is wound into a cylindrical shape so that the 1 st direction (heat-shrinkable direction) of the film is the circumferential direction, and the 1 st end portion is laminated and bonded to the 2 nd end portion to form a sealed portion 71, thereby forming a cylindrical film 7 (heat-shrinkable cylindrical label C). The overlapped portion may be integrally bonded, or a small circumferential portion of the overlapped portion may be non-bonded and the remaining large portion may be bonded. The width of the overlap of the 1 st side end and the 2 nd side end (the transverse length of the seal portion 71) is, for example, 2mm to 15mm, preferably 3mm to 10 mm. The seal portion 71 extends in a band shape in the longitudinal direction of the heat-shrinkable tubular label C.

The method for bonding the 1 st end portion and the 2 nd end portion is not particularly limited, and examples thereof include welding using a solvent, bonding using an adhesive, and the like.

The circumferential length of the cylindrical film 7 (heat-shrinkable cylindrical label C) is, for example, more than 1 times the maximum circumferential length of the portion to be attached of the container B and not more than 1.5 times the maximum circumferential length of the portion to be attached of the container B, preferably 1.01 times the maximum circumferential length of the portion to be attached of the container B to 1.3 times the maximum circumferential length of the portion to be attached of the container B, and more preferably 1.02 times the maximum circumferential length of the portion to be attached of the container B to 1.15 times the maximum circumferential length of the portion to be attached of the container B.

A colored printed layer (not shown) may be provided on the heat-shrinkable film (cylindrical film 7) as needed. The colored printed layer is a typical design printed layer showing desired characters, patterns, and the like. The colored print layer is provided over the entire or a part of the heat shrinkable film (cylindrical film 7). A preferred mode of the range in which the colored print layer is provided will be described later.

In the case where the colored print layer is provided on the back surface side of the heat shrinkable film (the back surface of the heat shrinkable film becomes the inner surface when it is a heat shrinkable tubular label C), a transparent heat shrinkable film is used. In the present specification, the term "transparent (colorless transparent or colored transparent) means a case where the total transmittance is 70% or more, preferably 80% or more, and more preferably 90% or more. Here, the total transmittance is a value measured by a measurement method using jis k 7361 (test method for total transmittance of plastic-transparent material) as a standard.

Further, an optional functional layer may be provided on the heat shrinkable film as necessary. Examples of the functional layer include a surface protective layer and a smoothing layer.

The colored print layer, the functional layer, and the like are conventionally known as components of the heat-shrinkable tubular label C, and a known structure can be adopted in the present invention.

The unsealing cross-sectional line 8 formed in the surface of the cylindrical film 7 extends in the circumferential direction thereof. In the illustrated example, the opening cross-sectional line 8 is formed over the entire circumference of the tubular film 7. Of course, the opening cross-sectional line 8 is not limited to be formed over the entire circumference of the tubular film 7, and may be formed in the circumferential direction of the tubular film 7 except for a part thereof. In this case, the opening cross-sectional line 8 is preferably formed over the entire circumference × 3/4 of the tubular film 7.

The opening transverse support line 8 may be formed parallel to the circumferential direction of the tubular film 7 as in the illustrated example, or may be formed slightly inclined with respect to the circumferential direction of the tubular film 7 (for example, 3 degrees or less with respect to the circumferential direction). The transversely extending opening line 8 formed obliquely with respect to the circumferential direction is preferably contained in the specific region at least 3/4 of the total length thereof, and more preferably contained in the specific region as a whole. As described above, the circumferential direction of the tubular film 7 corresponds to the lateral direction when the heat-shrinkable tubular label C is made flat.

Here, in the present specification, the "auxiliary line" refers to a line formed on the tubular film 7 so as to facilitate the breaking of the tubular film 7, and examples thereof include an easy-tear line, a half-cut line, and a combination thereof.

The tear line is a line including a plurality of intermittently formed through holes. That is, the tear line is a linear line in which the through holes and the uncut portions (non-through portions) are alternately connected and extend in 1 direction, and conceptually, it can be said that the tear line is 1 line obtained by connecting a plurality of through holes. The half cut line is a line formed by connecting cuts cut in a V-shaped cross section in the thickness direction of the cylindrical film 7.

The auxiliary line is preferably a tear line. In the illustrated example, the easy-tear lines are used as all the auxiliary lines.

Examples of the shape of the through hole of the easy-tear line in a plan view include a long and narrow linear shape, a substantially circular shape, a substantially elliptical shape, a V shape, a Y shape, and the like. Since the fracture trace extending along the auxiliary line is formed into a beautiful substantially linear shape, the through-hole of the easy-tear line has a long, thin, linear, substantially circular, or substantially elliptical shape in a plan view.

When the opening transverse auxiliary line 8 is formed of a tear line, the transverse length of the through hole of the tear line is, for example, 0.05mm to 2mm, preferably 0.5mm to 1.5 mm. The transverse length of the uncut portion of the opening transverse support line 8 (the transverse length of the uncut portion is equal to the interval between the through holes adjacent in the transverse direction) is, for example, 0.05mm to 2mm, preferably 0.5mm to 1.5 mm. The plurality of through holes of the tear line may have different lateral lengths from the plurality of uncut portions, but as shown in the drawing, the plurality of through holes may preferably have the same length and the plurality of uncut portions may preferably have the same length.

When the tubular film 7 (heat-shrinkable tubular label C) is divided into the upper tubular portion 7a and the lower tubular portion 7b with the opening transverse auxiliary line 8 as a reference, the opening longitudinal auxiliary line 9 is provided in at least one of the upper tubular portion 7a and the lower tubular portion 7b, preferably in both of them.

For example, the vertical opening assisting line 9 includes a 1 st vertical assisting line 91 provided in the upper cylindrical portion 7a of the cylindrical film 7, a 2 nd vertical assisting line 92 provided in the lower cylindrical portion 7b of the cylindrical film 7, and a 3 rd vertical assisting line 93 continuously provided in the range of the upper cylindrical portion 7a and the lower cylindrical portion 7b of the cylindrical film 7.

The 1 st vertical auxiliary line 91 forms an opening starting point of the upper cylindrical portion 7a of the heat-shrinkable cylindrical label C, and is formed to facilitate cutting of the upper cylindrical portion 7 a.

The 1 st auxiliary vertical line 91 is formed, for example, to extend from the upper end of the tubular film 7 to the opening transverse auxiliary line 8 in the vertical direction. The 1 st auxiliary vertical line 91 may be 1, but is preferably provided in a pair at a distance in the circumferential direction. The pair of 1 st auxiliary vertical lines 91 may be formed parallel to the longitudinal direction, or may be formed slightly inclined with respect to the longitudinal direction as shown in the drawing. The pair of 1 st vertical auxiliary lines 91 illustrated in the drawing are formed in an inclined straight line shape so that the interval becomes shorter as going downward.

The interval between the pair of 1 st vertical auxiliary lines 91 is not particularly limited, and is, for example, 5mm to 20 mm. The interval between the pair of 1 st vertical auxiliary lines 91 has two intervals, i.e., a longer interval and a shorter interval in the entire circumference of the tubular film 7, and here, is referred to as a shorter interval. In addition, when the interval between the pair of 1 st vertical auxiliary lines 91 is not uniform in the vertical direction, the interval means the maximum value thereof.

The 2 nd vertical auxiliary line 92 is formed to form an opening starting point of the lower cylindrical portion 7b of the heat-shrinkable cylindrical label C and to facilitate cutting of the lower cylindrical portion 7 b.

The 2 nd vertical auxiliary line 92 may extend downward in the longitudinal direction from the upper end of the lower cylindrical portion 7b (that is, the horizontal auxiliary line 8 for unsealing), or may extend upward in the longitudinal direction from the lower end of the lower cylindrical portion 7b (the lower end of the cylindrical film 7). Preferably, as shown in the figure, the 2 nd vertical auxiliary line 92 is formed to extend in the vertical direction from the opening transverse auxiliary line 8. The upper end of the 2 nd vertical auxiliary line 92 may coincide with the opening lateral auxiliary line 8, or may be positioned in the vicinity of the lower side or the vicinity of the upper side of the opening lateral auxiliary line 8. The 2 nd vertical auxiliary line 92 formed so that the upper end of the 2 nd vertical auxiliary line 92 is positioned in the vicinity of the upper side of the opening horizontal auxiliary line 8 slightly extends from the upper cylindrical portion 7 a. The 2 nd vertical auxiliary line 92 is preferably provided so that the upper end of the 2 nd vertical auxiliary line 92 is located in the vicinity of the upper side of the opening transverse auxiliary line 8 and extends in the longitudinal direction downward therefrom, and more preferably extends in the longitudinal direction from approximately 2mm above the opening transverse auxiliary line 8. By forming the longitudinal direction from the position of approximately 2mm on the upper side toward the lower side as described above, the 2 nd vertical auxiliary line 92 intersecting the opening lateral auxiliary line 8 can be reliably formed even when the forming position of the opening lateral auxiliary line 8 slightly fluctuates from the design value in manufacturing the heat-shrinkable tubular label C.

The 2 nd vertical auxiliary line 92 may extend continuously from the lower end of the 1 st vertical auxiliary line 91, but is preferably formed to be offset from the 1 st vertical auxiliary line 91 in the circumferential direction as shown in the drawing.

The 2 nd vertical auxiliary line 92 may be formed from the opening lateral auxiliary line 8 to the lower end of the tubular film 7, or may be formed from the opening lateral auxiliary line 8 to a middle portion of the lower tubular portion 7b of the tubular film 7 as shown in the drawing. The number 2 of the auxiliary vertical lines 92 may be 1, but it is preferable that the auxiliary vertical lines are provided in pairs at intervals in the circumferential direction. The pair of 2 nd vertical auxiliary lines 92 may be formed parallel to the longitudinal direction as illustrated in the figure, or may be formed slightly inclined with respect to the longitudinal direction.

The pair of 2 nd vertical auxiliary lines 92 are preferably disposed across the seal portion 71, but may be disposed at a position not across the seal portion 71.

The interval between the pair of 2 nd vertical auxiliary lines 92 is not particularly limited, and is, for example, 5mm to 15 mm. The interval between the pair of 2 nd vertical auxiliary lines 92 has two intervals, i.e., a longer interval and a shorter interval in the entire circumference of the tubular film 7, and here, is referred to as a shorter interval. In addition, when the interval between the pair of 2 nd vertical auxiliary lines 92 is not uniform in the vertical direction, the interval means the maximum value thereof.

The 3 rd vertical auxiliary line 93 is formed to complement the 2 nd vertical auxiliary line 92.

The 3 rd vertical auxiliary line 93 is formed laterally of the 2 nd vertical auxiliary line 92 and in the vicinity of the 2 nd vertical auxiliary line 92. The vicinity includes, for example, a range within 3mm in the circumferential direction from the 2 nd vertical auxiliary line 92. In addition, the vicinity includes one side or the other side in the circumferential direction, or one side and the other side in the circumferential direction with respect to the 1 nd auxiliary line 92. For example, in the case where 1 longitudinal auxiliary line 3 is formed in the vicinity of 1 second longitudinal auxiliary line 92, the 3 rd longitudinal auxiliary line 93 may be formed in the vicinity of the outer side of the 1 second longitudinal auxiliary line 92 as shown in the example, or may be formed between the pair of second longitudinal auxiliary lines 92.

The 3 rd vertical auxiliary line 93 is formed in at least the lower cylindrical portion 7b of the cylindrical film 7. For example, the 3 rd vertical auxiliary line 93 is formed at least in the lower cylindrical portion 7b of the cylindrical film 7 and in a portion from the opening lateral auxiliary line 8 to a middle portion of the lower cylindrical portion 7b, and preferably at least in the lower cylindrical portion 7b of the cylindrical film 7 and in a portion from the opening lateral auxiliary line 8 to a lower end of the cylindrical film 7. In the illustrated example, a 3 rd auxiliary line 93 is formed from the upper end to the lower end of the cylindrical film 7 in the longitudinal direction.

In the example shown in the figure, 1 longitudinal auxiliary line 3 is formed near one 2 nd longitudinal auxiliary line 92, but may be formed near each of the pair of 2 nd longitudinal auxiliary lines 92.

The 3 rd auxiliary vertical line 93 may be formed parallel to the longitudinal direction as in the illustrated example, or may be formed slightly inclined with respect to the longitudinal direction.

When the 1 st, 2 nd, and 3 rd vertical auxiliary lines 91, 92, and 93 (opening vertical auxiliary line 9) are each constituted by a tear line, the vertical length of the through-hole of the tear line is independently, for example, 0.05mm to 2mm, and preferably 0.3mm to 1.5 mm. The longitudinal length of each uncut portion (the longitudinal length of each uncut portion is equal to the interval between longitudinally adjacent through holes) is, for example, 0.05mm to 2mm, preferably 0.5mm to 1.5 mm. The plurality of through holes of the tear line and the plurality of uncut portions may have different longitudinal lengths, but as shown in the illustrated example, the plurality of through holes may have the same length and the plurality of uncut portions may have the same length.

In the illustrated example, the longitudinal lengths of the through holes of the 1 st and 3 rd auxiliary longitudinal lines 91 and 93 are independent of each other, and are, for example, 0.1 to 2mm, preferably 0.3 to 1mm, and the longitudinal lengths of the uncut portions are independent of each other, and are, for example, 0.1 to 2mm, preferably 0.3 to 1.0 mm. The longitudinal length of the through-hole of the 2 nd auxiliary longitudinal line 92 is, for example, 0.3 to 2mm, preferably 0.5 to 1.5mm, and the longitudinal length of the uncut portion thereof is, for example, 0.5 to 1.5mm, preferably 0.3 to 1 mm.

The heat-shrinkable tubular label C can be produced by a conventionally known method.

For example, a horizontal opening assisting line 8 and a vertical opening assisting line 9 are formed at predetermined positions in the surface of a long-strip-shaped heat-shrinkable film. The order of forming these is not particularly limited, and they may be formed in sequence, or after several of them are formed together, the remaining portions may be formed in sequence or together.

Examples of the method of forming the opening lateral auxiliary line 8 and the opening vertical auxiliary line 9 include a mechanical processing method such as a roller cutter or a cutting tool such as a needle, and a thermal processing method using a laser beam or the like.

For example, the 1 st end and the 2 nd end of the heat-shrinkable film in a longitudinal tape form having the opening transverse auxiliary line 8 and the opening longitudinal auxiliary line 9 are laminated and bonded to each other, thereby obtaining a continuous body in which the heat-shrinkable tubular labels C are continuously joined. The continuous body is cut to obtain heat-shrinkable tubular labels C.

Further, after the 1 st end portion and the 2 nd end portion of the longitudinal band-shaped heat shrinkable film on which the 2 nd longitudinal auxiliary line 92 and the 3 rd longitudinal auxiliary line 93 are formed are laminated and bonded to form a longitudinal cylindrical film, the 1 st longitudinal auxiliary line 91 and the opening transverse auxiliary line 8 are formed, and a continuous body in which the heat shrinkable cylindrical labels C are continuously joined is obtained. By cutting the continuous body, each heat-shrinkable tubular label C is obtained. Alternatively, after the longitudinal cylindrical film is formed in the same manner as described above, the longitudinal cylindrical film is cut while forming the 1 st longitudinal auxiliary line 91 and the opening transverse auxiliary line 8, thereby obtaining each heat-shrinkable cylindrical label C.

[ Container ]

Fig. 7 is a front view of the container, fig. 8 is an enlarged front view of the vicinity of the lid of the container, and fig. 9 is a cross-sectional view of the vicinity of the lid of the container taken along a longitudinal direction.

Referring to fig. 7 to 9, the container B includes a container body 1 including a mouth portion 14, and a lid body 2 for closing the mouth portion 14 of the container body 1.

The container body 1 includes a bottom portion 11, a body portion 12, and a mouth portion 14 in this order from below, and an opening is formed inside the mouth portion 14. The bottom surface portion 11, the body portion 12, and the mouth portion 14 are integrally formed. The material of the container body 1 is not particularly limited, and examples thereof include synthetic resin, glass, metal, and ceramics.

The container B can be self-standing with the bottom surface 11 as a self-standing surface. The inside of the body 12 and the mouth 14 forms a storage space for storing contents.

The content is not particularly limited, and examples thereof include foods such as seasonings, beverages, pharmaceuticals, cosmetics, and the like. The form of the content may be either liquid or granular.

The main body 12 may be a straight tube shape (a shape in which the circumferential length does not change in the longitudinal direction), or may be a special-shaped tube shape (a shape in which the circumferential length changes in the longitudinal direction) as illustrated. For example, the circumference of the main body portion 12 is not uniform in the longitudinal direction, and the main body portion 12 has portions whose circumferences are different in the longitudinal direction. The main body 12 in the illustrated example has a substantially circular truncated cone shape whose circumferential length becomes shorter as it goes upward.

Further, although not particularly shown, the main body 12 may be formed with a groove portion extending in the circumferential direction and recessed inward.

A mouth portion 14 is formed above the body portion 12. A neck ring portion 16 is provided so as to project below an outer peripheral wall 18 of the mouth portion 14. Further, a protruding engagement portion 17 is provided above the outer peripheral wall 18 of the mouth portion 14. In the illustrated example, the engaging portion 17 is a protruding engaging convex portion, but may be formed in a concave shape (may be an engaging concave portion).

The lid body 2 has: a mounting portion 4 having an outer wall portion 3 fitted to an outer peripheral wall 18 of the mouth portion 14 of the container body 1; and a lid 5 openably and closably attached to the upper side of the mounting portion 4.

The lid 5 may have a known tamper-evident, i.e., a tamper-evident ring (not shown).

The lid 2 is usually formed of a synthetic resin, but the lid 5 may be formed of a material other than a synthetic resin, such as a metal.

The mounting portion 4 has at least an outer wall portion 3, and the outer wall portion 3 is a portion for mounting the lid body 2 to the mouth portion 14 of the container body 1.

The mounting portion 4 has: an outer wall portion 3 which can be fitted to an outer peripheral wall 18 of the mouth portion 14 of the container body 1; an intermediate portion 41 formed above the outer wall portion 3; and a take-out portion 42 which is formed above the intermediate portion 41 and into which the lid portion 5 is fitted, and which further includes an inner wall portion 43 which abuts on the inner side of the outer peripheral wall 18 of the mouth portion 14 as necessary.

The outer wall 3, the intermediate portion 41, and the removal portion 42 are formed in a cylindrical shape having an opening on the inside.

The outer wall portion 3 is formed of a cylindrical portion protruding downward from the intermediate portion 41, and is fitted over the outer surface of the outer peripheral wall 18 of the mouth portion 14. In particular, the engaged portion 31 engaged with the engaging portion 17 of the outer peripheral wall 18 is provided around the outer wall 3, and by engaging the engaged portion 31 of the outer wall 3 with the engaging portion 17, the outer wall 3 engaged with the outer peripheral wall 18 of the mouth portion 14 is strongly fitted to the outer peripheral wall 18 to such an extent that it is difficult to pull out upward.

Further, a cylindrical inner wall portion 43 protruding downward from the intermediate portion 41 is formed inside the outer wall portion 3. The inner wall 43 is fitted into the inner surface of the outer peripheral wall 18 of the mouth portion 14. The outer peripheral wall 18 of the mouth portion 14 is sandwiched between the outer wall portion 3 and the inner wall portion 43, and the mounting portion 4 is more strongly mounted to the outer peripheral wall 18 of the mouth portion 14.

The mounting portion 4 is strongly fitted via the outer wall portion 3 so as not to be easily detached from the outer peripheral wall 18 of the mouth portion 14, but the outer wall portion 3 of the mounting portion 4 of the present invention is provided with a mechanism for releasing the fitting with respect to the mouth portion 14.

The release mechanism can release the fitting of the outer wall portion 3 to the outer peripheral wall 18 of the mouth portion 14, and includes a release start point portion accessible from the outside of the outer wall portion 3.

The releasing means may be an outer wall structure capable of cutting off a part of the outer wall 3 by human force, and may be, for example, a structure in which a part of the outer wall 3 is formed weaker than other parts.

Examples of the release start point portion include a grip portion provided in a part of the outer wall portion 3 and capable of being gripped by a fingertip. By pulling out the release starting point portion by pinching, the thin portion is broken, and a part of the outer wall portion 3 is separated from the outer wall 18 of the mouth portion 14, so that the fitting of the outer wall portion 3 can be easily released.

The outer wall portion 3 having the release mechanism of the present embodiment will be described in detail below, but the present invention is not limited to the following structure.

The outer wall portion 3 is formed in a substantially cylindrical shape covering the outer side of the outer peripheral wall 18 as a whole, and a release starting point portion is formed by forming a notch portion 32 in a part thereof.

Specifically, the outer wall portion 3 is formed to be thin in the circumferential direction at a longitudinally intermediate portion thereof. In fig. 8, in order to show the thin-walled portion in a manner that can be easily distinguished, an infinite number of dots are added to the thin-walled portion for convenience (the same applies to fig. 10). Hereinafter, the portion formed to be thin in the circumferential direction will be referred to as "peripheral thin portion 33".

Referring to fig. 9, an engaged portion 31 is formed on the inner side of the outer wall portion 3 with reference to a peripheral thin portion 33 extending in the circumferential direction. For example, the engaged portion 31 is formed of a protrusion in which a part of the outer wall portion 3 is thickened so as to be engageable with a lower portion of the engaging portion 17.

The engaged portion 31 may be formed continuously over the entire circumferential range, or may be formed in plural numbers at intervals in the circumferential direction.

The outer wall 3 is formed with a notch 32 cut in the plane from the lower end thereof. The cutout portion 32 extends upward from the lower end of the outer wall portion 3 and extends in the circumferential direction at a longitudinally intermediate portion. Preferably, the distal end of the cut-out portion 32 is located substantially on the peripheral thin portion 33.

By forming the notch portion 32 in the outer wall portion 3, a grip portion 35 which can be gripped by a fingertip can be defined from the outer wall portion 3. The lower end of the grip portion 35 is located on the extension of the lower end of the outer wall portion 3 in the circumferential direction. The grip portion 35 can be easily gripped by pulling up with a fingertip from the lower side of the outer wall portion 3.

In order to prevent the grip portion 35 from being accidentally warped, a weak bridge portion 36 is formed in a part of the cutout portion 32 to such an extent that the grip portion 35 is easily broken when pulled out with a fingertip. The bridge 36 may be formed continuously at the lower end of the grip portion 35, but as shown in the figure, the bridge 36 is formed at the upper portion of the grip portion 35 apart from the lower end of the grip portion 35, so that the grip portion 35 can be easily pulled up with the fingertips from the lower side of the outer wall portion 3.

The grasping portion 35 is a release starting point portion accessible from the outside of the outer wall portion 3 when releasing the fitting of the outer wall portion 3 to the outer peripheral wall 18 of the mouth portion 14.

Further, the circumferential middle portion of the outer wall portion 3 is formed to be thin in the longitudinal direction so as to penetrate the thick engaged portion 31. In fig. 8, in order to show the thin-walled portion in a manner that can be easily distinguished, an infinite number of dots are added to the thin-walled portion for convenience (the same applies to fig. 10). Hereinafter, the portion formed to be thin in the longitudinal direction will be referred to as a "longitudinally thin portion 34".

An opening communicating with the opening of the mouth portion 14 of the container body 1 is formed inside the taking-out portion 42, and the content stored in the container body 1 is taken out through the opening of the taking-out portion 42. The lid body 2 in the illustrated example has a middle plug 44 for closing the opening of the removal portion 42. The middle plug 44 is connected to the inside of the removal portion 42 via a thin portion. By pulling the pull ring 45 provided to the middle plug 44, the middle plug 44 can be removed and the removal portion 42 can be opened. A screw portion to be screwed to the lid portion 5 is formed on the outer peripheral surface of the removal portion 42.

The cap 5 is used to close the opening of the mouth 14 of the container body 1.

The lid 5 is screwed to the screw portion of the removal portion 42 by a screwing action. The lid 5 opens and closes the mouth 14 of the container body 1 via the take-out portion 42.

After the container body 1 is filled with the contents, the outer wall portion 3 of the lid body 2 is fitted to the outer peripheral wall 18 of the mouth portion 14, whereby a container B as shown in fig. 7 to 9 is obtained.

The mounting portion 4 having the release mechanism can be easily detached from the mouth portion 14 of the container body 1 as follows (see fig. 10).

When the bridge 36 is broken by pulling up the grip portion 35 as the release starting point portion with a fingertip and the grip portion 35 is pulled out outward in the circumferential direction by gripping the fingertip, the outer wall portion 3 is broken in the circumferential direction along the circumferential thin portion 33. When the pulling-out is further performed, the peripheral thin portion 33 is broken along the vertical thin portion 34. When the outer wall portion 3 is broken along the vertical thin portion 34, the engagement of the engaged portion 31 with the engaging portion 17 is partially released, and therefore the outer wall portion 3 of the mounting portion 4 can be detached from the mouth portion 14.

[ Container with Label ]

A labeled container a as shown in fig. 1 to 3 can be formed by attaching a heat-shrinkable tubular label C to the container B filled with the contents.

The heat-shrinkable tubular label C is attached to at least the upper part of the container B including the lid body 2. The heat-shrinkable tubular label C of the illustrated example is attached from the body portion 12 of the container body 1 up to the upper surface peripheral portion of the cover portion 5. More specifically, the heat-shrinkable tubular label C is bent toward the upper peripheral edge of the lid portion 5 of the container B and is substantially in close contact therewith, and is substantially in close contact therewith from the lid portion 5 and the outer wall portion 3 of the lid body 2 along the outer surface of the body portion 12 of the container body 1. The heat-shrinkable tubular label C is attached in a so-called full-shrink type.

In addition, the full shrink type also includes a case where the heat-shrinkable tubular label C does not reach the bottom surface portion 11 of the container body 1.

The heat-shrinkable tubular label C may be attached to the upper portion of the container B including the lid body 2 in a so-called lid seal type attachment method.

The heat-shrinkable tubular label C is attached to the container B such that the opening cross-sectional line 8 is disposed corresponding to a region from the lower end of the outer wall portion 3 to the lower end of the lid portion 5. In other words, the heat-shrinkable tubular label C heat-shrunk and attached to the container B has the opening cross-sectional line 8 formed in a region from the lower end of the outer wall portion 3 to the lower end of the lid portion 5.

The position of the opening cross-sectional line 8 is not particularly limited as long as it is within a specific region. Preferably, the heat-shrinkable tubular label C is attached to the container B such that the opening cross-sectional line 8 is positioned between the position 1/2 on the outer wall portion 3 and the lower end of the lid portion 5.

The position 1/2 corresponds to a position from the lower end 1/2 of the outer wall portion 3 when the longitudinal length of the outer wall portion 3 is 1.

When the labeled container a is used, the tubular film 7 is broken by the 1 st vertical auxiliary line 91 to cut the upper tubular portion 7a of the heat-shrinkable tubular label C, and the tubular film 7 is broken by the opening horizontal auxiliary line 8 to remove the upper tubular portion 7 a.

When the upper cylindrical portion 7a of the heat shrinkable cylindrical label C is removed, the lid portion 5 is exposed as shown in fig. 11 and 12.

Since the label-attached container a of the present invention has the opening transverse assist line 8 arranged in the specific region, substantially the entire lid portion 5 is exposed after the upper cylindrical portion 7a of the heat-shrinkable cylindrical label C is removed. Therefore, the lid 5 can be opened and closed without any trouble, and the labeled container a can be used by taking out the contents. Further, since the opening cross-sectional line 8 is disposed in the specific region, the lower cylindrical portion 7B is attached to the container B including at least a part of the outer wall portion 3 after the upper cylindrical portion 7a is removed. In particular, when the lateral opening assisting line 8 is disposed between the position 1/2 of the outer wall portion 3 and the lower end of the lid portion 5, the lower cylindrical portion 7B remains in the container B in a state of covering substantially the entire grip portion 35 (release start point portion) of the outer wall portion 3.

As described above, the lower cylindrical portion 7b remains in a state of being attached to the outer wall portion 3, and the lower cylindrical portion 7b functions to protect the outer wall portion 3, and makes it difficult to access the grip portion 35 (release start portion) of the outer wall portion 3. Therefore, in the process of using the labeled container a, the mounting portion 4 of the lid body 2 can be prevented from being detached from the container body 1 by pulling out the grip portion 35 by mistake.

After the use of the labeled container a without the contents is completed, the lower cylindrical portion 7b is broken and removed by the 2 nd vertical auxiliary line 92, so that the grip portion 35 (the release start portion) of the outer wall portion 3 can be easily accessed. By pulling out the grip portion 35, the fitting of the outer wall portion 3 to the outer peripheral wall 18 of the mouth portion 14 is released, and the mounting portion 4 can be easily detached from the mouth portion 14.

When the heat-shrinkable tubular label C is removed entirely in this manner, the lid body 2 including the outer wall portion 3 can be easily detached from the container body 1, and therefore, the labeled container a which is easy to recycle can be provided.

The labeled container of the present invention is not limited to the above-described embodiment, and can be appropriately modified in design within the intended scope of the present invention. In the following, other embodiments of the present invention will be described, but in this description, configurations and effects different from those of the above-described embodiments will be mainly described, and the same configurations and the like as those of the above-described embodiments will be referred to by terms or reference numerals as they are, and the description of the configurations may be omitted.

In the above embodiment, the number of the opening cross support lines 8 is 1 in the tubular film 7, but it is preferable that at least 2 are formed at a slight interval in the longitudinal direction as shown in fig. 13, for example. In the illustrated example, 2 opening cross support lines 8 are formed at a slight interval in the longitudinal direction.

When 2 or more opening cross-sectional lines 8 are formed adjacently, it is preferable that the heat-shrinkable tubular label C is attached to the container B so that all the opening cross-sectional lines 8 are arranged to correspond to the specific region.

As shown in fig. 14, the pair of 2 nd vertical auxiliary lines 92 in the above embodiment may be configured by long through holes 921 having a relatively large vertical length and short through holes 922 having a smaller vertical length than the long through holes. In this case, the long through hole 921 is formed from the opening cross-sectional line 8. The number of the long through holes 921 may be 1, or 2 or more, but when the heat-shrinkable tubular label C is heat-shrunk, relatively large holes are generated due to the long through holes, and therefore 1 is preferable. The short through holes 922 are formed in a plurality of numbers below the long through holes 921 without being cut (the short through holes 922 correspond to the through holes of the 2 nd vertical auxiliary line 92 described in the above embodiment). The longitudinal length of the long through hole 921 is preferably 3mm to 5 mm.

By forming the 2 nd vertical auxiliary line 92 having such long through holes 921, a pinch portion (a portion between the pair of long through holes 921) is generated at the upper end portion of the lower cylindrical portion 7b of the container remaining after the upper cylindrical portion 7a is removed along the horizontal auxiliary line 8 for unsealing.

As shown in fig. 15, the 2 nd vertical auxiliary line 92 of the above embodiment may be configured by a plurality of lower through holes 923 extending downward from the opening lateral auxiliary line 8 and upper through holes 924 continuous with the lower through holes 923 and extending upward from the opening lateral auxiliary line 8. In this case, it is preferable that no opening transverse auxiliary line is formed between the pair of 2 nd vertical auxiliary lines 92, 92 (that is, the opening transverse auxiliary line 8 formed in the circumferential direction of the cylindrical film 7 except for a part thereof is applied), and the transverse through-hole 925 is formed so as to extend between the pair of upper through- holes 924, 924 at the upper end of the upper through-hole 924.

The number of the upper through-holes 924 and the transverse through-holes 925 may be 1 or more, and preferably, a plurality of through-holes are formed.

By forming the 2 nd vertical auxiliary line 92 having the upper through-hole 924 and the transverse through-hole 925 as described above, a pinching portion (a portion divided by the pair of upper through-holes 924 and transverse through-holes 925) is generated which protrudes from the upper end of the lower cylindrical portion 7b of the container remaining after the upper cylindrical portion 7a is removed along the unsealing transverse auxiliary line 8.

In addition, in the heat-shrinkable tubular label C of the above embodiment, the case of forming the label into a tubular shape from before the label is attached to the container has been described, but the heat-shrinkable tubular label of the present invention is not limited thereto, and may be formed into a tubular shape while being attached to the container.

A heat-shrinkable tubular label formed into a tubular shape while being attached to a container is formed by partially adhering an inner surface (back surface) of a part of a heat-shrinkable film to an attached portion of the container B so that a heat-shrinking direction of the film is in a circumferential direction, then winding the film around the container, and laminating and adhering a 1 st end portion of the heat-shrinkable film to a 2 nd end portion thereof to form a heat-shrinkable tubular label C. Such a heat-shrinkable tubular label is generally called a wound tubular label or a wound label, and is formed into a tubular shape while being attached to a container. The heat-shrinkable tubular label is heat-shrunk by heating and is attached to the container in a sealed manner.

The heat-shrinkable tubular label formed in a tubular shape in advance and the heat-shrinkable tubular label formed in a tubular shape by being attached to a container are different in the timing of forming the label in a tubular shape in the production, but the heat-shrinkable film, the auxiliary thread formed therein, the attachment position of the label to the container, and the like are the same.

In the case where the lid portion 5 has a known tamper-evident score ring (not shown), the unsealing cross-sectional line 8 extending in the circumferential direction may be formed so as to correspond to a region from the upper end of the outer wall portion 3 to the lower end of the lid portion 5 (i.e., a region from the lower end to the upper end of the tamper-evident score ring). Thus, even after the upper cylindrical portion 7a of the heat-shrinkable cylindrical label C is removed, the entire outer wall portion 3 including the nip portion 35 (release starting point portion) is covered with the lower cylindrical portion 7 b.

[ Heat-shrinkable tubular label and labeled container having colored print layer in preferred range ]

Fig. 16 is a perspective view of a heat-shrinkable tubular label provided with a colored printed layer, and fig. 17 is a front view of a labeled container having the heat-shrinkable tubular label and a container heat-shrunk with the heat-shrinkable tubular label attached.

The colored print layer is provided on the heat-shrinkable film (cylindrical film 7) so as to print a desired color ink thereon. Examples of the design printing layer include plain printing layers of plain single color having no pattern; a design printing layer for expressing a desired design (characters, numbers, line drawings, designs, etc.) by using a single color or two or more color inks; a laminated printing layer formed by overlapping the plain printing layer and the design printing layer; and a combination printing layer in which a plain printing layer and a design printing layer are arranged.

The colored print layer can be roughly classified into a colored transparent print layer and a colored opaque print layer according to the concentration and color of the colored ink and the like and the thickness of the print layer. Either a colored transparent or opaque printed layer may be provided.

In a preferred embodiment, the color printed layer is provided in the cylindrical film 7 in a range covering the release starting point portion (the nip portion 35) of the lid body 2. The colored printed layer may be provided on the entire cylindrical film 7. Preferably, a colored printed layer is provided in a part of the cylindrical film 7 and is not provided in a part thereof. Hereinafter, a portion of the cylindrical film 7 where the color printed layer is not provided may be referred to as a "blank portion". The inside can be seen from the outside of the blank part of the cylindrical film 7 having no color printed layer. Preferably, the blank portion of the cylindrical film 7 is colorless and transparent.

In order to enable visual confirmation of the contents put in the container B from the outside of the heat-shrinkable cylindrical label C, it is preferable that no colored printed layer be provided in all or a part of the range corresponding to the container body 1 in the cylindrical film 7.

The heat-shrinkable tubular label C of fig. 16 is provided with colored printed layers 61, 62 on the tubular film 7 except for the lower side of the auxiliary line 8 for unsealing. The lower range is a portion (blank portion) of the cylindrical film 7 where the color printed layer is not provided. In the illustrated example, the blank portion a is present in a band-like range extending in the circumferential direction, for example.

Fig. 17 shows a labeled container a to which a heat-shrinkable tubular label C having the colored printed layers 61 and 62 and a margin a is attached. In each drawing, a region where the colored printed layer is provided is shaded with thin lines, and a margin portion a is left blank.

Referring to fig. 17, the release starting point portion (the nip portion 35) of the lid body 2 is covered with the colored printed layer 61 of the heat-shrinkable tubular label C. On the other hand, a portion below the lid body 2 and above the body 12 of the container body 1 is covered with a blank portion a of the heat-shrinkable tubular label C. In addition, most of the body portion 12 of the container body except the upper portion is covered with the colored print layer 62 of the heat-shrinkable tubular label C.

Fig. 18 is an enlarged front view of the labeled container a in the vicinity of the lid body after the upper cylindrical part of the heat-shrinkable cylindrical label C is removed by the opening assisting line 8. After the upper cylindrical portion is removed, the lower cylindrical portion 7B of the heat-shrinkable cylindrical label C is attached to the container B including the outer wall portion 3. Further, the release start point portion (the nip portion 35) of the lid body 2 covered with the color printed layer 61 is not visible from the outside or is difficult to be visible. Therefore, the user can be reliably prevented from detaching the attachment portion 4 by pulling out the grip portion 35 by mistake.

On the other hand, the lower cylindrical portion 7B of the heat-shrinkable cylindrical label C remaining in the container has a blank portion a, and the content in the container B can be visually confirmed from the outside through the blank portion a.

The length of the margin a in the longitudinal direction is not particularly limited, but if it is too small, it is difficult to visually confirm the content, and if it is too large, the formation range of the colored printed layer becomes relatively small. The length L (see fig. 17) of the blank portion a in the longitudinal direction depends on the size of the container, but is, for example, 3mm to 80mm, preferably 10mm to 50 mm.

In the illustrated example, the blank portion a extends over the entire circumferential direction of the tubular film 7 (heat-shrinkable tubular label C), but the invention is not limited thereto. For example, the blank part a may be set in a range of 1/4 to 3/4, where the entire circumferential direction (circumferential length) of the tubular film 7 (heat-shrinkable tubular label C) is 1.

As shown in fig. 19, a 2 nd space portion b may be provided. The 2 nd space portion b is provided in a band-like range extending in the longitudinal direction in the cylindrical portion 7b below the cylindrical film 7.

For the labeled container a to which the heat-shrinkable tubular label C having the 2 nd margin b is attached, the 2 nd margin b exists substantially throughout the longitudinal direction of the main body portion 12 of the container body 1. The remaining amount of the content in the container B can be visually checked from the outside through the 2 nd margin portion B. Instead of the blank portion a, only the 2 nd blank portion b may be provided.

Industrial applicability

The labeled container of the present invention can be used as a container for containing any content such as seasoning.
