The container body 11 has a mouth portion 12, a neck portion 13, a shoulder portion 14, and a body portion 15. The mouth portion 12, the neck portion 13, the shoulder portion 14, and the body portion 15 are continuous in order along the axial direction.

The mouth portion 12 is located on the other end 11b side of the container body 11. The mouth portion 12 opens toward the side opposite to the side on which 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. The outer peripheral surface of the mouth portion 12 may be provided with a spiral groove portion that engages with the lid portion 16.

The body portion 15 is located on the one end 11a side of the container body 11. The outer shape of the body portion 15 is generally larger than the outer shape of the mouth portion 12. The body portion 15 includes a portion of the container body 11 having the maximum peripheral length. In the first embodiment, the peripheral length of the body portion 15 increases once toward the one end 11a side of the container main body 11 along the axial direction, and the portion having the maximum peripheral length is further extended to the one end 11a of the container main body 11. It has a shape in which the circumference becomes smaller as it goes toward it. The circumference of the body portion 15 may be substantially constant in the axial direction.

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

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

The container body 11 is a soft container obtained by blow molding a synthetic resin such as polyethylene, polypropylene, polyamide, polyester, etc., and is a multi-layer container or the like in which a single layer or a gas barrier layer is laminated, and presses the body portion 15. It is a container used for the purpose of taking out the contents to the outside. That is, the container body 11 has a squeeze property.

The inside of the container body 11 contains, for example, liquids such as beverages, seasonings, and chemicals. The contents contained in the container main body 11 are not limited to these, and gel-like ones or granular ones can be appropriately adopted 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-shaped portion facing the opening of the mouth portion 12 and an outer peripheral wall portion hanging from the peripheral edge of the plate-shaped portion. On the inner surface of the outer peripheral wall portion of the lid portion 16, for example, an engaged portion that is engaged with the spiral groove portion provided on the outer peripheral portion of the mouth portion 12 is provided.

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 cylindrical shape and covers the container 10. More specifically, the label 20 has a bag-like shape with one closed in the axial direction. 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 located at substantially the same height as one end 11a of the container body 11. It is preferable that one end 21 of the label 20 is located closer to one end 11a of the container body 11 than the position where the maximum peripheral length of the body portion 15 is obtained.

The other end 22 side of the label 20 is sealed by a second joint portion 52, which will be described later. The other end 22 side of the label 20 faces the lid portion 16 at a distance from the lid portion 16. There is a sealed space between the other end 22 of the label 20 and the lid portion 16.

The label 20 includes a portion corresponding to the shape of the body portion 15 of the container 10. The label 20 has a small peripheral length in the vertical direction (both in the axial direction) with respect to the portion having the maximum peripheral length corresponding to the portion having the maximum peripheral length of the body portion 15 and the portion having the maximum peripheral length. Includes the part that becomes. When these come into contact with the body portion 15, the label 20 is attached to the body portion 15. The label 20 is held by the body portion 15 due to its elasticity as described later.

The label 20 may be provided with a break line 23. The break line 23 is a perforation or a half cut consisting of intermittent cuts, and is provided along the circumferential direction of the label 20. By pulling the other end 22 side of the label 20, the label 20 can be separated along the break line 23. As a result, the label 20 of the portion located on the other end 22 side can be separated while the label 20 of the portion located on the one end 21 side is in close contact with the body portion 15.

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

When the printing layer 40 is formed inside the film base material 30, it is possible to prevent the printing 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 in a front-to-back relationship in the thickness direction. The film substrate 30 has a first end 31 and a second end 32 located at both ends around the axis.

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

More specifically, in the film base material 30, the first end portion 31 is folded back so that the second surface 30b faces the first end side folded portion 33, and the second end portion 32 has the second surface 30b. It has 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 are joined by a first joint portion 51 extending along the axial direction.

In this case, the overlapping allowance 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. The thickness is preferably 0.3 mm or less. As a result, it is possible to suppress the formation of wrinkles in the vicinity of the first joint portion 51.

The bonding mode between the first end 31 side and the second end 32 side of the film base material 30 is not limited to the above. For example, in a state where the second surface 30b of the portion located on the first end portion 31 side and the first surface 30a of the portion located on the second end portion 32 side are overlapped, these are formed by the first joint portion 51. It may be joined. Further, in a state where the first surface 30a of the portion located on the first end portion 31 side and the second surface 30b of the portion located on the second end portion 32 side are overlapped, these are formed by the first joint portion 51. It may be joined. The first joint portion 51 can be formed by a heat seal or a fusing seal that heat-seals the film surfaces, or an adhesive seal that adheres to the joint surface via an adhesive. As the adhesive, a two-component curable urethane-based adhesive or the like can be used. Further, a corona treatment, an anchor treatment, or the like may be applied to the film surface in order to improve the adhesiveness.

As described above, when the first surface 30a of one of the first end portion 31 and the second end portion 32 and the other second surface 30b of the first end portion 31 and the second end portion 32 are overlapped with each other. The stacking allowance becomes large, for example, about 2 mm to 15 mm. In this case, the first joint portion 51 is formed large.

The film base material 30 is made of a self-stretchable film. The self-stretchable film is not particularly limited, but is a general term for films having "stretchability" and "restorability". "Stretchability" means the property and ease of stretching of a self-stretchable film. Further, "stability" means the property of contracting (returning to the original) by the elastic force when the external force is released after the self-stretchable film is stretched. "Stretchability" and "restorability" are collectively referred to as "stretchability", and unlike a heat-shrinkable film, a self-stretchable film can shrink regardless of heat.

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

The self-stretchability was evaluated as follows. 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 marked lines 100 ± 2 mm) was prepared from a self-stretchable tubular film substrate. A 60% tensile test was performed with the long side direction (circumferential direction of the tubular stretch label) of this sample piece as the measurement direction, and the instantaneous strain (%) was measured. The 60% tensile test is a crosshead speed constant type or pendulum type tensile tester (test speed: 50 ± 5 mm / min), and a predetermined load (N) is applied to reduce the distance between the marked lines of the sample piece. In this test, the distance was extended to 60%, and the distance between the marked lines when the load was removed and returned to 0 (N) after the test was read, and the instantaneous strain (%) was calculated by the following formula.

Instantaneous distortion (%) = 100 × ΔL2 / L2

As such a self-stretchable film, for example, a film containing an olefin resin such as polyethylene and a thermoplastic resin such as an ethylene-vinyl acetate copolymer can be adopted. More specifically, as the self-stretchable film, 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 ). , A single-layer or multi-layer film having a thickness of 10 μm to 100 μm and made of a thermoplastic resin such as an ethylene-vinyl acetate copolymer can be adopted.

As shown in FIG. 3, the film base material 30 has an end portion 35 located on the one end 21 side of the label 20 and an end portion 36 located on the other end 22 side of the label 20. On the end portion 36 side of the film base material 30, the first surfaces 30a are bonded to each other by the second bonding portion 52. Several ventilable holes or cuts (having a length of about 1 mm to 5 mm) are provided in the vicinity of the second joint portion 52 (separated by about 5 mm to 20 mm). The holes and cuts can discharge the air trapped between the label 20 and the container 10 to the outside of the label 20 when the label 20 is put on (inserted) into the container 10.

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

The second joint 52 extends along the first direction intersecting the axial direction. Specifically, the second joint portion 52 extends along the width direction of the film base material 30 orthogonal to the axial direction. In the present embodiment, the case where the second joint portion 52 is linear is exemplified, but as long as the other end side of the label 20 is sealed, the second joint portion 52 is from one end side of the film base material 30 in the width direction. It may be provided so as to straddle the other end side. The second joint 52 may be formed in a convex shape (R shape) so that the central portion in the width direction bulges to one side in the axial direction, or may be formed in a wavy shape, as appropriate. The shape can be changed.

As shown in FIG. 1 again, the end portion 36 of the film base material 30 located on the other end 22 side of the label 20 has

corner portions

39a and 39b on both sides in the width direction. Each of the

corner portions

39a and 39b is recessed toward the inside of the tubular film base material 30 when viewed from the outside of the tubular film base material 30.

Since the

corners

39a and 39b are recessed toward the inside of the tubular film base material 30, the skin is 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 base material 30 is made of a self-stretchable film, the film base material 30 is formed by using low-density polyethylene, linear low-density polyethylene, or ethylene-vinyl acetate copolymer. It can soften itself. Therefore, the above effect can be exerted 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 the first joining portion 51 and a second overlapping region R2 overlapping the second joining portion 52. The print layer 40 is formed on the second surface 30b so as to extend to the first overlapping region R1 and the second overlapping region R2. More specifically, the print layer 40 is entirely formed on the second surface 30b. In such a case, the display area can be increased and the cosmeticity can be improved.

The film base material 30 is preferably transparent so that the print layer 40 formed inside the film base material 30 can be visually recognized from the outside of the label 20.

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 side of the first end portion 31 and the second end portion 32. When the second surface 30b of the portion located at is overlapped and joined, the print layer 40 is not formed on the second surface 30b overlapping with the first joining portion 51. In this case, the print layer 40 is preferably formed so as to cover at least the second overlapping region R2 of the second surface 30b. That is, the print layer 40 may be formed on the second surface 30b excluding the first joint portion 51.

FIG. 4 is a flow chart showing a manufacturing flow for manufacturing the labeled container according to the first embodiment. 5 to 15 are views showing various steps in the manufacturing process of the labeled container according to the first embodiment, and the state of the long body and the film base material in the predetermined step. A method for manufacturing the labeled container 100 will be described with reference to FIGS. 4 to 15. For convenience, the above-mentioned print layer 40 is omitted in FIGS. 4 to 15.

As shown in FIG. 4, the method for manufacturing the labeled container 100 according to the first embodiment includes a step S10 for preparing the label 20 and a step S20 for coating the label 20 on the container 10.

Step S10 includes step S11 for preparing the tubular film base material 30. In step S11, the first surface 30a and the second surface 30b, which are in a front-to-back relationship in the thickness direction, and the first end portions 31 and the second end portions 32 located at both ends in the axial direction are provided. The shape is formed so that the 30a faces inward and the second surface 30b faces outward, and the portion located on the first end 31 side and the portion located on the second end 32 side are joined by the first joint 51. A tubular film base material is prepared in which the first surfaces 30a facing each other are joined by the second joining portion 52 on the end portion 36 side located on the other end 22 side of the label 20 in the axial direction. In this case, as the film base material, a film in which the print layer 40 is entirely formed on the second surface 30b may be prepared.

Specifically, the step S11 includes a step S111 for preparing a long body, a step S112 for joining the long body, and a step S113 for cutting the long body.

FIG. 5 is a plan view showing a step of preparing a long body in the manufacturing process of the labeled container according to the first embodiment. FIG. 6 is a cross-sectional view of a long body along the VI-VI line shown in FIG.

As shown in FIGS. 4 to 6, in the step S111 for preparing a long body, a tubular long body 60 extending along a direction parallel to the axial direction is prepared. In this case, the long body 60 corresponds to the first main surface 60a corresponding to the first surface 30a, the second main surface 60b corresponding to the second surface 30b, and the first end portion 31 around the axis. A self-stretchable film having one side end portion 61 and the other side end portion 62 corresponding to the second end portion 32 around the axis is used. In addition, as the elongated body 60, the first main surface 60a is formed into a cylinder so as to face inward and the second main surface 60b faces outward, and the portion located on the one side end portion 61 side and the other side end portion 62. A self-stretchable film is used in which a portion located on the side is joined by a joining portion 51A.

More specifically, it is located on the first main surface 60a and the other side end 62 of the portion located on one side end 61 so that the first main surface 60a faces inward and the second main surface 60b faces outward. A tubular self-stretchable film is used in which the first main surface 60a of the portion is overlapped and joined by the joining portion 51A. In this case, as the long body, the one in which the print layer 40 is formed on the second main surface 60b as a whole may be used. The joint portion 51A corresponds to the first joint portion 51 in the label 20.

It should be noted that the position is located on the first main surface 60a of the portion located on one end side of the one side end portion 61 and the other side end portion 62, and on the other end side of the one side end portion 61 and the other side end portion 62. The second main surface 60b of the portion to be formed may be overlapped and these may be joined by the joining portion 51A.

Further, the long body 60 joined by the joining portion 51A includes an upstream side end portion 60c and a downstream side end portion 60d located on the upstream side in a direction parallel to the axial direction.

FIG. 7 is a diagram showing a step of joining long bodies in the manufacturing process of the labeled container according to the first embodiment.

As shown in FIGS. 4 and 7, in the step S112 of joining the long bodies 60, the first main surfaces 60a facing each other at a position separated from the downstream end portion 60d on the upstream side by a predetermined distance in the axial direction. The second joint portion 52 is formed by joining along the first direction intersecting with the above. The second joint portion 52 is not limited to a linear shape, and may be formed so as to straddle the long body 60 from one end side to the other end side in the width direction. For example, the second joint portion 52 may be formed in a convex shape (R shape) so that the central portion in the width direction bulges toward the upstream end portion 60c, or may be formed in a wavy shape. , The shape can be changed as appropriate.

The break line 23 may be formed at the same time as the second joint portion 52 is formed. As a result, it is possible to omit a separate step of providing the break line 23, and the manufacturing process can be simplified.

Further, at the same time as forming the second joint portion 52, the above-mentioned breathable hole or cut may be formed by perforation or the like. The ventilable hole or cut may be formed in the step of cutting a long body described later.

FIG. 8 is a diagram showing a step of cutting a long body in the manufacturing process of the labeled container according to the first embodiment.

As shown in FIGS. 4 and 8, in the step S113 for cutting the long body 60, the long body 60 is cut in the first direction intersecting the axial direction on the upstream side of the second joint portion 52. Thereby, the tubular film base material 30 provided with the first joint portion 51 and the second joint portion 52 is cut out. Specifically, the elongated body 60 is cut along the dividing line CL extending in the direction orthogonal to the axial direction on the upstream side of the second joint portion 52. As a result, the end portion 35 of the film base material 30 located on the one end 21 side of the label 20 is opened, and the end portion 36 of the film base material 30 located on the other end 22 side of the label is sealed by the second joint portion 52. The tubular film base material 30 is cut out. At this time, the peripheral length of the tubular film base material 30 is smaller than the maximum peripheral length of the container 10 because the elastic film is stretched and attached to the container by elastic force. For example, the peripheral length of the tubular film base material 30 is 3% to 40% smaller, preferably 15% to 30% smaller than the maximum peripheral length of the container 10.

In the above description, the case where the process S113 is performed after the process S112 has been illustrated and described, but the present invention is not limited to this. Step S112 and step S113 may be performed at the same time, or step S112 may be performed after step S113.

Subsequently, as shown in FIG. 4, a step S20 of covering the container 10 with the label 20 is carried out. The step S20 includes a step S21 of turning over the film base material 30, a step of widening the opening 21a of the label 20, and a step of inserting the container 10 into the opening 21a.

In carrying out the step S20, first, in the step S21, the film base material 30 is turned inside out so that the first surface 30a faces the outside and the second surface 30b faces the inside. Specifically, the step S21 includes a step S211 for holding the film substrate and a step S212 for pushing the pushing member.

In the present embodiment, the second direction exemplifies the axial direction and the direction orthogonal to the first direction, but is a direction parallel to the first direction as long as the film base material 30 can be held. It may be a direction that intersects the axial direction and the first direction.

Specifically, the opening 21a (the opening of the end 35 of the film substrate 30) provided at one end 21 of the label 20 has, for example, a circular, semicircular, or arcuate cross section and an axial length. The pair of

metal holders

holders

81, 82 are provided so as to be close to each other and separable from each other, for example, in the second direction intersecting in the axial direction. By inserting the pair of

holders

81 and 82 into the openings 21a and separating them from each other, the film base material 30 in the expanded portion of the openings 21a tends to shrink toward the pair of

holders

81 and 82. .. In this way, the film base material 30 can be held by the pair of

holders

81 and 82 by utilizing the elasticity of the film base material 30.

The pair of

holders

81 and 82 is not limited to the above configuration. Each of the pair of

holders

81 and 82 may be configured to hold the film base material 30 by sandwiching the first surface 30a of the film base material 30 and the second surface 30b of the film base material 30.

Further, the number of holders is not limited to two as long as the film base material 30 can be held, and may be four or six depending on the cross-sectional shape of the container. Further, a wide shape that spreads in a plane along the circumferential direction of the container 10 may be used. Further, the position where the film base material 30 is held by the holder is not limited to both ends, and can be appropriately selected. That is, at least a part of the film base material 30 may be retained. As the plurality of holders, for example, in order to widen the opening 21a from the inside to the outside, a rod-shaped or claw-shaped jig having an axial length that can be arranged apart in the circumferential direction may be adopted. ..

It should be noted that it is not necessary to push the

corners

39a and 39b from the outside in order to dent the

corners

39a and 39b. By forming the film base material 30 with a self-stretchable film, the

corner portions

39a and 39b are spontaneously recessed inside the film base material 30 in the step of turning over the film base material 30.

Specifically, the pair of

holders

91 and 92 are inserted into the opening 21a (the opening of the end 35 of the film substrate 30) provided at one end 21 of the label 20. The pair of

holders

91 and 92 are provided so as to be separable in the second direction, for example, intersecting in the axial direction. By inserting the pair of

holders

91 and 92 into the opening 21a and separating them from each other, the opening 21a can be widened.

holders

91 and 92 are not limited to the above configuration as long as they are provided so as to be separable from each other. Each of the pair of

holders

91 and 92 may be configured to hold the film base material 30 by sandwiching the first surface 30a of the film base material 30 and the second surface 30b of the film base material 30. In this case, the opening 21a can be widened by separating the pair of

holders

Specifically, both ends of the end portion 35 of the film base material 30 located on the one end 21 side of the label 20 are held, and the opening 21a formed on the one end 21 side of the label 20 is widened.

More specifically, the film is formed by inserting a pair of

holders

81 and 82 into the opening 21a (the opening of the end 35 of the film base material 30) provided at one end 21 of the label 20 and separating them from each other. The opening 21a is widened while holding the base material 30.

As described above, the number of holders is not limited to two as long as the opening 21a can be widened while holding the film base material 30, and may be four or six depending on the cross-sectional shape of the container. Further, a wide shape that spreads in a plane along the circumferential direction of the container 10 may be used. Further, the position where the film base material 30 is held by the holder is not limited to both ends, and can be appropriately selected. That is, at least a part of the film base material 30 may be retained.

The step S211A may be performed with the label 20 facing the container 10. Further, after the step S211A, the label 20 may face the container 10 with the opening 21a widened. The label 20 faces the container 10 so that the end 36 of the film substrate 30 faces the lid 16 of the container 10.

holders

81, 82. You may move it to.

By relatively pushing the container 10 toward one end 21 side of the label, the end portion 36 of the film substrate 30 is located below the end portion 35 of the film substrate 30, and the film substrate 30 is changed from the state where the end portion 36 is located below the end portion 35 of the film substrate 30. It changes to a state where it is located above the end portion 36.

Further, in the direction in which the second joint 52 extends (vertical to the paper surface in FIG. 18), the corners 39a provided on both ends of the end 36 of the film base material 30 located on the other end 22 side of the label 20. , 39b are recessed toward the inside of the film base material 30.

FIG. 19 is a diagram showing a post-state of the second step shown in FIG. Further, by pushing the container 10 relatively toward one end 21 side of the label, the state in which the film base material 30 is held by the pair of

holders

81 and 82 is released. This allows the container 10 to be covered with the inverted label 20, as shown in FIG.

As described above, the labeled container 100 is manufactured based on the above-mentioned manufacturing method and the first modification thereof, so that the end portion of the film base material 30 located on the other end 22 side of the label 20 is manufactured. At 36, a first folded portion 37 and a second folded portion 38 that are folded so as to face one end 21 side of the label 20 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 the inside of the label 20, so that it is second in appearance. The joint portion 52 can be made inconspicuous.

Further, at the roots of the first folded portion 37 and the second folded portion 38, a portion curved so as to be convex outward is formed on the outside of the label 20. Therefore, a good touch can be obtained.

Therefore, the first joint portion 51 can also be made inconspicuous in appearance.

Further, since a curved portion is formed at the bases of the first end side folded portion 33 and the second end side folded portion 34 so as to be convex outward, a good touch can be obtained.

Further, as described above, since the print layer 40 can be formed also in the second overlapping region R2 overlapping the second joint portion 52 on the second surface 30b, the display area can be increased. Similarly, when the first end side folded portion 33 and the second end side folded portion 34 are formed, the print layer 40 is also formed in the first overlapping region R1 overlapping the first joint portion 51. Can be done. As a result, the print layer 40 can be formed on the second surface 30b as a whole, so that good cosmetic properties can be obtained.

Further, since the print layer 40 is formed inside the label 20, it is possible to prevent the print layer 40 from being peeled off due to vibration or friction when the labeled container 100 is distributed by transportation or the like.

auxiliary members

122 and 124 also move in the same manner as the reversing

auxiliary members

122 and 124.

By such movement, the inversion auxiliary members 121 to 124 utilize the elasticity of the film base material 30 to spread the film base material 30 in the circumferential direction, and invert the non-inverted portion of the film base material 30. The film is brought into contact with the surface of the container 10 along the shape of the container 10. Further, by blowing air from the reversing auxiliary members 121 to 124, the non-reversed portion of the film base material 30 can be smoothly inverted without being damaged. The inversion auxiliary members 121 to 124 are not limited to the plate shape, and may be any jig that can move in the axial direction and invert the non-inverted portion.
