Description

The present invention relates to labeled containers.

2. Description of the Related Art In recent years, various labels using a self-stretchable film substrate have been proposed as labels used for labeled containers. Labels using such self-elastic film substrates are disclosed in JP-A-2014-145967 (Patent Document 1) and JP-A-2014-069816 (Patent Document 2).

Japanese Patent Application Laid-Open No. 2014-145967 (Patent Document 1) discloses a tubular label that is open at both ends in the axial direction. The portion and the second end are joined. Specifically, the label substrate has a first surface constituting an inner surface, and the first surface at the first end and the first surface at the second end are adhered in a state of being overlapped. It is

Further, Japanese Patent Application Laid-Open No. 2014-069816 (Patent Document 2) discloses a tubular label having a strip-shaped sealing portion that seals the upper end of the label. The strip-shaped sealing portion is formed by bonding the inner surfaces of the label base material to each other on the upper end side of the label.

JP 2014-145967 A JP 2014-069816 A

However, in Patent Document 1, the portion where the first surface of the first end and the first surface of the second end are overlapped and adhered is provided so as to protrude toward the outside of the label. Also in Patent Document 2, the sealing portion formed on the upper end side of the label protrudes toward the outside of the label.

In such a case, the portion where the inner surfaces of the label substrates are overlapped and adhered protrudes outside the label, and is conspicuous in appearance. Furthermore, the portion where the inner surfaces of the label substrates are adhered to each other has a high rigidity and a poor feel to the touch.

In order to improve these problems, it is conceivable to invert the label and attach it to the container with the adhesive (protruding) part facing inward. The label may be damaged due to vibration during distribution and transportation, impact when dropped, or the like.

The first end and the second end face the inner side of the tubular film substrate. The cross-section of the container perpendicular to the axial direction at the portion where the label is attached has a pair of curved portions that are convex outward and face each other such that the centers of the cross-sections are positioned between them. have A line connecting the apexes of the pair of curved portions is the long axis in the cross section. The first joint portion is arranged at a position shifted in the circumferential direction from the top portion.

In the labeled container based on the present disclosure, the cylindrical film substrate has one end and the other end in the axial direction. In this case, the one end side of the film substrate may be open, and the other end side of the film substrate may be closed by a second joint. Further, in this case, the other end of the film substrate may have a first folded portion and a second folded portion that are folded back so as to face the one end, and the first folded portion The first surface and the second surface of the second folded portion may be joined together by the second joining portion in an overlapping state.

The container body 11 has one end 11a and the other end 11b in the height direction. The container body 11 has a mouth portion 12 , a neck portion 13 , a shoulder portion 14 and a body portion 15 . These mouth portion 12, neck portion 13, shoulder portion 14, and body portion 15 are continuous in order along the height direction.

The mouth portion 12 is positioned on the side of the other end 11b of the container body 11 . The mouth portion 12 opens toward the side opposite to the side where the body portion 15 is located. The inner peripheral length of the mouth portion 12 is substantially constant. The mouth portion 12 is a portion covered by the lid portion 16 . A spiral groove that engages with the lid portion 16 may be provided on the outer peripheral surface of the mouth portion 12 .

The trunk portion 15 is positioned on the one end 11 a side of the container body 11 . The outer shape of the trunk portion 15 is larger than the outer shape of the mouth portion 12 as a whole. The trunk portion 15 includes a portion of the container main body 11 having the maximum peripheral length. The trunk portion 15 has a circumferential length that once increases from the shoulder portion 14 toward the one end 11a of the container body 11 along the height direction, and further moves toward the one end 11a of the container body 11 from the maximum circumferential length. It has a shape in which the peripheral length becomes smaller as it increases. In addition, the circumferential length of the body portion 15 may be substantially constant in the height direction. A cross section of the trunk portion 15 orthogonal to the height direction has, for example, an elliptical shape. Note that the cross-sectional shape is not limited to an elliptical shape, as will be described later.

Shoulder 14 is connected to body 15 . The shoulder portion 14 is provided so that the circumferential length becomes smaller toward one side in the height direction (the mouth portion 12 side). The shoulder portion 14 has a shape that curves inward toward one side in the height direction when viewed in a cross section parallel to the height direction.

Neck portion 13 connects mouth portion 12 and shoulder portion 14 . The neck portion 13 extends substantially linearly when viewed in a cross section parallel to the height direction. The neck portion 13 may be provided so that the peripheral length becomes smaller toward one side in the height direction, or may be provided so that the peripheral length is substantially constant.

The container body 11 is a flexible container obtained by blow molding a synthetic resin such as polyethylene, polypropylene, polyamide, polyester, etc., and is a multi-layered container or the like in which a single layer or a gas barrier layer is laminated. It is a container that is used for the purpose of discharging the contents to the outside. That is, the container body 11 has squeezability.

Inside the container body 11, for example, liquids such as beverages, seasonings, and medicinal solutions are accommodated. Note that the contents contained in the container body 11 are not limited to these, and gel-like or granular contents can be appropriately employed as long as they can be taken out from the mouth portion 12 .

The lid portion 16 is provided so as to close the mouth portion 12 . The lid portion 16 has a cap shape, and has a plate-like portion that faces the opening of the mouth portion 12 and an outer peripheral wall portion that hangs down from the periphery of the plate-like portion. The inner surface of the outer peripheral wall portion of the lid portion 16 is provided with, for example, an engaged portion that engages with the spiral groove portion provided on the outer periphery of the mouth portion 12 .

The label 20 has one end 21 and the other end 22 in the axial direction (DR1 direction). The axial direction is a direction parallel to the height direction of the container body 11 described above. The label 20 has a tubular shape and covers the container 10 . More specifically, the label 20 has a bag-like shape with one end in the axial direction closed. The label 20 is provided so as to cover the container body 11 in the circumferential direction and cover the lid portion 16 of the container body 11 .

One end 21 side of the label 20 has an opening 21a. One end 21 of the label 20 is positioned at substantially the same height as the one end 11 a of the container body 11 . One end 21 of the label 20 is preferably positioned closer to the one end 11 a of the container body 11 than the position where the trunk portion 15 has the maximum circumferential length.

The other end 22 side of the label 20 is sealed with a second joint portion 52 which will be described later. The other end 22 side of the label 20 faces the lid portion 16 with a gap therebetween. A space exists between the other end 22 of the label 20 and the lid portion 16 .

Label 20 includes a portion corresponding to the shape of body 15 of container 10 . The label 20 has a portion having the maximum circumference corresponding to the portion having the maximum circumference of the body portion 15, and a circumference having a length in the vertical direction (both in the height direction) with respect to the portion having the maximum circumference. and a smaller portion. The label 20 is attached to the body portion 15 by bringing these into contact with the body portion 15 . As will be described later, the label 20 is held on the body portion 15 by the self-elasticity of the film substrate 30 (see FIG. 2).

The label 20 has a held portion 25 and a cover portion 26 . The held portion 25 is a portion held by the container 10 by contacting the peripheral surface of the container 10 due to its self-elasticity. More specifically, the held portion 25 contacts part of the peripheral surface of the trunk portion 15 . The cover portion 26 is positioned closer to the other end 22 of the label 20 (on the end portion 36 side of the film substrate 30 described later) than the held portion 25 and is a portion that covers the container 10 . The cover portion 26 is provided with a ventilation portion 24 which will be described later.

The label 20 may be provided with a breaking line 23 . The breaking line 23 is formed by intermittent perforations or half-cuts, and is provided along the circumferential direction of the label 20 . The label 20 can be separated along the breaking line 23 by pulling the other end 22 side of the label 20 . As a result, the portion of the label 20 located on the side of the one end 21 is kept in close contact with the body 15, the portion of the label 20 located on the side of the other end 22 is separated, and the lid 16 is removed to take out the contents. can be done. After separation, one end 21 remains on the body 15 as a label.

On the side of the other end 22 of the label 20, several ventilation parts 24 are provided so that air can enter and exit from the outside. Ventilation part 24 is, for example, a hole or cut (having a length of about 1 mm to 5 mm) that allows ventilation. The holes and cuts can discharge air trapped between the label 20 and the container 10 to the outside of the label 20 when the label 20 is placed over (inserted into) the container 10 .

As shown in FIG. 2, label 20 includes film substrate 30 and printing layer 40 . As will be described later, the printed layer 40 is formed inside the film substrate 30 . The printed layer 40 can be formed by gravure printing, flexographic printing, or the like.

When the printed layer 40 is formed inside the film substrate 30, it prevents the printed layer 40 from peeling off due to vibration or friction with other objects when the labeled container 100 is distributed by transportation or the like. can do.

The film base material 30 has a first surface 30a and a second surface 30b that are opposite to each other in the thickness direction. The film substrate 30 has a first end portion 31 and a second end portion 32 located at both ends around the axis.

A portion of the film substrate 30 located on the first end 31 side and a portion of the film base 30 located on the second end 32 side are joined by a first joining portion 51 .

More specifically, the film substrate 30 includes a first end side folded portion 33 folded back so that the first end portion 31 faces the second surface 30b, and a second end portion 32 that faces the second surface 30b. and a second end side folded portion 34 that is folded back so as to face.

The first surface 30a of the first end-side folded portion 33 and the first surface 30a of the second end-side folded portion 34 overlap each other, and a first joint portion 51 extends along the axial direction. joined by Bonding is preferably heat-sealing by heat-sealing the film surfaces together or fusion-cut sealing by heat, since stable strength can be obtained with a small overlap.

In this case, the overlapping margin between the first surface 30a of the first end-side folded portion 33 and the first surface 30a of the second end-side folded portion 34 is, for example, about 0.1 mm to 2.0 mm. and preferably 0.3 mm or less. Thereby, formation of wrinkles in the vicinity of the first joint portion 51 can be suppressed.

The joining mode between the first end portion 31 side and the second end portion 32 side of the film substrate 30 is not limited to the above. The second surface 30b of the portion located on the second end portion 32 side may be joined by the first joint portion 51 in a state of being overlapped, or the second surface 30b of the portion located on the first end portion 31 side may be joined. The second surface 30b and the first surface 30a located on the second end 32 side may be joined together by the first joining portion 51 in a state of being overlapped. Thus, when the first surface 30a of one of the first end 31 and the second end 32 and the second surface 30b of the other of the first end 31 and the second end 32 are overlapped and joined, may use an adhesive instead of heat sealing. As the adhesive, a two-component curable urethane adhesive or the like can be used. In addition, the film surface may be subjected to corona treatment, anchor treatment, or the like in order to improve adhesiveness.

Note that, as described above, when the first surface 30a of the first end-side folded portion 33 and the first surface 30a of the second end-side folded portion 34 are joined together, the impact causes the first joint portion 51 to collapse. breakage (more specifically, breakage of the edge portion of the seal portion of the first joint portion 51 (the portion along the seal)) is likely to occur, so by applying the configuration of the present disclosure, damage to the label described later can be prevented. The suppressing effect can be exhibited more remarkably.

The film substrate 30 is composed of a self-stretchable film. The self-stretchable film is a general term for films having "stretchability" and "restoration", although there is no particular limitation. The term "stretchability" means the property and easiness of stretching the self-stretchable film. Moreover, "restorability" means the property of shrinking (returning to the original state) due to elastic force when the external force is released after stretching the self-stretchable film. "Stretchability" and "restorability" are collectively referred to as "elasticity", and unlike heat-shrinkable films, self-stretchable films can be shrunk without heat.

It is preferable that the film substrate can be stretched at least 60% or more in the circumferential direction and has an instantaneous strain (50 mm/min) of 13% or less after being stretched 60% in the circumferential direction.

In addition, it performed as follows as evaluation of self-stretchability. A rectangular sample piece having a length of 15±0.1 mm in the height direction and a length of 200 mm in the circumferential direction (distance between gauge lines: 100±2 mm) was prepared from a cylindrical film substrate having self-elasticity. A 60% tensile test was performed with the longitudinal direction of the sample piece (peripheral direction of the tubular stretch label) as the measurement direction, and the instantaneous strain (%) was measured. A 60% tensile test means that a predetermined load (N) is applied using a constant crosshead speed or pendulum type tensile tester (test speed: 50 ± 5 mm / min), and the distance between the gauge lines of the sample piece is After the test, the distance between gauge lines was read when the load was removed and returned to 0 (N), and the instantaneous strain (%) was calculated by the following formula.
Instantaneous strain (%) = 100 x ΔL2/L2
L2: Distance between gauge lines of sample piece before test (mm)
ΔL2: Increase in the distance between the gauge marks of the sample piece after the test (mm)

As such a self-stretchable film, for example, a film containing an olefin resin such as polyethylene or a thermoplastic resin such as an ethylene-vinyl acetate copolymer can be employed. More specifically, low-density polyethylene (for example, density 0.91 to 0.93 g/cm ³ ), linear low-density polyethylene (for example, density 0.88 to 0.90 g/cm ³ ) are used as self-stretchable films. , ethylene-vinyl acetate copolymer, and other thermoplastic resins having a thickness of 10 μm to 100 μm.

As shown in FIG. 3, the film substrate 30 has an end portion 35 as one end and an end portion 36 as the other end in the axial direction. The end portion 35 is positioned on the one end 21 side of the label 20 . The end 36 is located on the side of the other end 22 of the label 20 . On the end portion 36 side, the first surfaces 30a are joined together by a second joint portion 52 .

The end portion 36 of the film substrate 30 has a first folded portion 37 and a second folded portion 38 folded back so as to face one end 21 of the label 20 . The first surface 30 a of the first folded portion 37 and the first surface 30 a of the second folded portion 38 are joined by a second joining portion 52 . The second joint portion 52 can be formed by, for example, pressing with a heat seal bar heated to about 110° C. to 180° C. to heat-seal the film surface.

The second joint portion 52 extends along a direction intersecting the axial direction. Specifically, when viewed from the axial direction, the second joint portion 52 extends along a crossing direction crossing a virtual line VL1, which will be described later. In the present embodiment, the second joint portion 52 is exemplified in a linear shape, but as long as the other end side of the label 20 is sealed, from one end side of the film base material 30 in the cross direction to the other side. It suffices if it is provided so as to straddle the end side. For example, the second joint portion 52 may be formed in a convex shape (R shape) so that the central portion in the cross direction bulges to one side in the axial direction, or may be formed in a wave shape. The shape can be changed as appropriate.

As shown in FIG. 1 again, the end portion 36 of the film substrate 30 located on the side of the other end 22 of the label 20 has corner portions 39a and 39b on both sides in the width direction. Each of the corners 39 a and 39 b is recessed toward the inside of the tubular film substrate 30 when viewed from the outside of the tubular film substrate 30 .

Since the corners 39a and 39b are recessed toward the inside of the cylindrical film substrate 30, the skin is not damaged by the corners 39a and 39b when the user grips the labeled container 100. can be suppressed. Further, as described above, when the film substrate 30 is composed of a self-stretchable film, the film substrate 30 can be formed by using low-density polyethylene, linear low-density polyethylene, or an ethylene-vinyl acetate copolymer. can soften itself. For this reason, the above effects can be exhibited more remarkably.

The print layer 40 is provided so as to cover at least a predetermined position on the second surface 30b. As shown in FIGS. 2 and 3, the second surface 30b has a first overlapping region R1 overlapping with the first joint portion 51 and a second overlapping region R2 overlapping with the second joint portion 52. As shown in FIGS. The printed layer 40 is formed on the second surface 30b so as to extend over the first overlapping region R1 and the second overlapping region R2. More specifically, the printed layer 40 is entirely formed on the second surface 30b. In such a case, the display area can be increased, and the beauty can be improved.

In order to make the printed layer 40 formed inside the film substrate 30 visible from the outside of the label 20, the film substrate 30 is preferably transparent.

As described above, the first surface 30a of the portion located on one end side of the first end portion 31 and the second end portion 32 and the other end portion side of the first end portion 31 and the second end portion 32 , the printed layer 40 is not formed on the second surface 30b that overlaps the first joint portion 51 . In this case, the printed layer 40 is preferably formed to cover at least the second overlap region R2 of the second surface 30b. That is, the printed layer 40 may be formed on the second surface 30b except for the first joint portion 51. As shown in FIG.

As shown in FIG. 2 again, the cross section of the trunk portion 15 perpendicular to the axial direction has a substantially elliptical shape. The cross-section to which the label 20 is attached has a pair of curved portions 17, 18 facing each other such that the center O of the cross-section is located therebetween. The pair of curved portions 17 and 18 are curved in a convex shape toward the outside. A pair of curved portions 17 and 18 have top portions P1 and P2, respectively. An imaginary line VL connecting the apex P1 and the apex P2 is the long axis in the cross section.

In addition, the cross-sectional shape is not limited to an elliptical shape, and may be a longitudinal shape including a major axis and a minor axis, and may be an oval shape such as an egg shape or a track shape. Also in this case, the cross section preferably includes a pair of curved portions, and preferably the imaginary line connecting the tops of the pair of curved portions is the long axis. For example, the ratio of the length of the long axis to the short axis is 105% or more and 300% or less, preferably 120% or more and 300% or less.

FIG. 4 is a cross-sectional view showing a modification of the cross-section of the labeled container. As shown in FIG. 4, a shape including a pair of flat plate portions 19 and a pair of curved portions 17 and 18 may be used as the longitudinal shape including the long axis and the short axis. The pair of flat plate portions 19 are substantially parallel to the long axis. The pair of curved portions 17 and 18 are opposed to each other with the center O positioned therebetween, and connect the ends of the pair of flat plate portions 19 . Note that the curvature of the pair of curved portions 17 and 18 can be changed as appropriate.

Here, as shown in FIG. 2 again, the first joint portion 51 is arranged to face the container 10 at a position displaced from the top portions P1 and P2 in the circumferential direction. At the apexes P1 and P2 where the imaginary straight line VL1 has the maximum length, the film substrate 30 having self-elasticity is stretched the most, and the tensile force acting on these portions increases. Therefore, when the labeled container 100 vibrates during distribution due to transportation or the like, or when the labeled container 100 is dropped, the impact may be concentrated on a portion where a large tensile force acts. The elongation rate of the film base 30 at the mounting position where the film base 30 is mounted on the container 10 is 101% or more and 160% or less. % or more and 130% or less.

In the present embodiment, as described above, the first joint portion 51 is arranged at a position displaced from the top portions P1 and P2 in the circumferential direction. Therefore, concentration of the impact on the first joint portion 51 can be suppressed. As a result, it is possible to prevent the label 20 from being damaged due to breakage of the first joint portion 51 . The amount of displacement from the tops P1 and P2 is 5 mm or more and 30 mm or less in the case of the elongation rate of the mounting position. When the amount of displacement is within the above range, the first joint portion 51 is arranged away from the center of the trunk portion 15 while mitigating the above impact, so that good design can be maintained.

Furthermore, as described above, at the end 36 of the film substrate 30 located on the side of the other end 22 of the label 20, the first folded portion 37 and the second folded portion are folded so as to face the one end 21 of the label 20. 38 are formed. As a result, the second joint portion 52 that joins the first surface 30a of the first folded portion 37 and the first surface 30a of the second folded portion 38 faces toward the inside of the label 20, so that the outer appearance is second. The joint portion 52 can be made inconspicuous.

At the roots of the first folded portion 37 and the second folded portion 38, outwardly curved portions 371 and 381 are formed outside the label 20. As shown in FIG. Therefore, a good feel can be obtained.

In addition, when the first end-side folded portion 33 and the second end-side folded portion 34 are also formed on the first joint portion 51 side, the first joint portion 51 is arranged to face the inner side of the label 20 . become. Therefore, it is possible to make the first joint portion 51 inconspicuous in appearance.

In addition, since outwardly curved portions 331 and 341 are formed at the roots of the first end-side folded portion 33 and the second end-side folded portion 34, a good feel is obtained.

FIG. 5 is a front view of a labeled container according to Embodiment 2. FIG. A labeled container 100A according to Embodiment 2 will be described with reference to FIG.

As shown in FIG. 5, the labeled container 100A according to the second embodiment differs from the labeled container 100 according to the first embodiment in the shape of the label 20A. Other configurations are the same.

The label 20A is formed in a tubular shape so that both the one end 21 side and the other end 22 side in the axial direction are open. That is, the label 20A mainly differs from the label 20 according to the first embodiment in that the cover portion 26 is not provided and the second joint portion 52 is not formed. Other configurations are substantially the same. In this case, the portion of the container 10 to which the label 20A is not attached is exposed from the label 20A.

In the labeled container 100A according to Embodiment 2 as well, the section perpendicular to the axial direction at the portion where the label 20A is attached has a shape corresponding to FIG. That is, as in the first embodiment, the first joint portion 51 is arranged at a position displaced from the top portions P1 and P2 of the pair of curved portions 17 and 18 in the circumferential direction. Therefore, substantially the same effects as in the first embodiment can be obtained in the second embodiment.
