Description

  The present invention relates to a composite film sheet, a label body, and a container with a label, and in particular, a long composite film sheet in which two films, at least one of which is a heat-shrinkable film, are bonded at a line-shaped adhesive portion, and the composite film The present invention relates to a label body formed from a sheet and a labeled container provided with the label body.

  As a composite film used for a cap seal or the like, a conventional heat-shrinkable film and a non-heat-shrinkable film are known that are bonded and integrated by a plurality of rows of line-shaped bonding portions. Here, the line-shaped adhesion portions and the non-adhesion portions are alternately arranged.

  And this composite film is usually rolled long, for example, having a width of 500 to 1000 mm, and is sandwiched by a plurality of rolls at the time of post-processing such as printing or bag making, and is elongated by the rotation of the roll. -Shaped composite film is fed out. In the rolled composite film, one end in the longitudinal direction is open to the atmosphere, but the other end is closed toward the roll core portion of the roll. Therefore, when the composite film is sandwiched and moved by the roll in the post-processing, a slight amount of air existing in the non-adhesive portion between the heat-shrinkable film and the non-heat-shrinkable film sandwiches the composite film. It is moved and collected by a roll, so to speak, it is shaped like a balloon filled with air being crushed from one side. Therefore, the composite film swells at the non-adhesive portion due to the accumulated air, and in some cases, the adhesive portion may be peeled off by the swelled air.

  Therefore, in Patent Document 1, as a composite film used for a cap seal or the like, a heat-shrinkable film and a non-heat-shrinkable film are bonded and integrated by a plurality of lines of line-shaped adhesive portions, In a non-adhered portion alternately arranged, a large number of pores having a size that allows air to escape are provided in one or both of the heat-shrinkable film and the non-heat-shrinkable film. Is disclosed.

  According to the prior art, a heat-shrinkable film and a non-heat-shrinkable film are bonded and integrated by a plurality of rows of line-shaped adhesive portions, and line-shaped adhesive portions and non-adhesive portions are alternately arranged. In the composite film, air can be removed, but providing a large number of thin holes in the non-adhesive portion is time consuming and increases costs. Moreover, when a hole is provided on the label front side, the label design may be affected.

  An object of the present invention is to provide a composite film sheet, a label body, and a container with a label, which can remove air from the composite film in a relatively simple manner and without affecting the design. A further object is to provide a composite sheet, a label body, and a container with a label that have a beautiful finish when mounted on a container while well venting air. The following means contribute to at least one of these purposes.

  In order to form a plurality of label bodies, the composite film sheet according to the present invention is a long composite film sheet in which a cutting position is determined with a dimension in the height direction of the label body along the longitudinal direction as a cutting pitch. A first film which is a heat-shrinkable film having a heat shrinkage rate in the width direction larger than the heat shrinkage rate in the longitudinal direction, and has a heat shrinkage rate different from the heat shrinkage rate of the first film, A second film that is superposed and bonded, a linear adhesive portion that is provided on either the first film or the second film, extends in the longitudinal direction, and is arranged at predetermined intervals in the width direction, and each line In the adhesive bonding portion, a separation portion provided with a predetermined separation length centering on the cutting position, and when the first film and the second film are overlapped and bonded, the separation length portion is Apart without film and second film adhesive, between the spaced apart length portions adjacent in the longitudinal direction and having a, a separation portion to be bonded in succession in a line.

  Moreover, in the composite film sheet which concerns on this invention, a separation | spacing part is provided for every 2 of the cutting positions along a longitudinal direction for every line-shaped adhesion part, and one of the adjacent line-shaped adhesion parts. Between, it is preferable to be provided at different cutting positions along the longitudinal direction.

  Moreover, in the composite film sheet according to the present invention, it is preferable that the separation portion is a portion where the adhesive is not provided in advance, or a portion where the adhesive is provided, but an adhesion lowering material that lowers the adhesiveness is also provided.

  Moreover, the label body according to the present invention is a label body used by cutting the composite film sheet along the longitudinal direction with the dimension in the height direction of the label body as a pitch between cutting positions, and the composite film sheet is The first film, which is a heat-shrinkable film having a heat shrinkage rate in the width direction larger than the heat shrinkage rate in the longitudinal direction, has a heat shrinkage rate different from the heat shrinkage rate of the first film, and is superposed on the first film. The second film to be bonded, the line-shaped adhesive portions provided on either the first film or the second film, extending in the longitudinal direction and arranged at predetermined intervals in the width direction, and each line-shaped adhesive Part is a separation part provided with a predetermined separation length at one end part or the other end part in the longitudinal direction of the label body, and when the first film and the second film are laminated and bonded together The separation length portion has a separation portion that is separated without adhering the first film and the second film, and is continuously adhered in a line shape between the separation length portions adjacent in the longitudinal direction. Are respectively provided at different end portions in the longitudinal direction of the label body between adjacent line-shaped adhesive portions.

  The labeled container according to the present invention is a labeled container provided with a label body, and the label body is a heat-shrinkable film having a thermal contraction rate in the width direction larger than the thermal contraction rate in the longitudinal direction. 1 film, a second film having a heat shrinkage rate different from the heat shrinkage rate of the first film, and is provided on either the first film or the second film; Line-shaped adhesive portions that extend in the longitudinal direction and are arranged at predetermined intervals in the width direction, and in each line-shaped adhesive portion, in a longitudinal direction that is predetermined at one end portion or the other end portion in the longitudinal direction of the label body It is a separation part provided with a separation length along, and when the first film and the second film are overlapped and bonded, the separation length portion is separated without bonding the first film and the second film, Next to the longitudinal direction Between the adjacent lengths of the label body in the longitudinal direction of the label body. Each is provided.

  According to at least one of the above-described configurations, the composite film sheet is bonded to the first film, which is a heat-shrinkable film, and the second film having a heat shrinkage rate different from the heat shrinkage rate of the first film at the line-shaped adhesive portion. In each of the line-shaped adhesive portions, a separation portion having a predetermined separation length with respect to the cutting position is provided. The first and second films are not bonded to each other in the separation length portion, and the separation length portions adjacent in the longitudinal direction are continuously adhered in a line shape. In this way, each line-shaped adhesive portion is always provided with a separation portion, and the non-adhesive portions are in communication with each other. Therefore, when the composite film is sandwiched and moved by the roll in the post-processing, The air in the non-adhesive part between each line-shaped adhesive part between the second film moves to the adjacent non-adhesive part one after another through the separation part, and is released to the outside from the end face of the composite sheet. Can do.

  Further, in the composite film sheet, the separation portion is provided for each line-shaped adhesive portion at every two cutting positions along the longitudinal direction, and between the adjacent line-shaped adhesive portions in the longitudinal direction. Are provided at different cutting positions. That is, between the cutting positions, each line-shaped adhesive portion has a separation portion at one end or the other end. A line-like adhesive portion having a separation portion at one end and a line-like adhesion portion having no separation portion are alternately arranged, and similarly, a line having a separation portion and a line-like adhesion portion having no separation portion at the other end of the cutting position. The adhesive portions are alternately arranged. As a result, the separation portions are gathered at the cutting position, so that the central portion of the label body between the cutting positions is sufficiently bonded. Thereby, since the non-adhesive part does not exist in the line-like adhesive part in the central part of the label body which is the main design part, a good unevenness, that is, a wrinkle is obtained when the container is heat-shrink mounted.

  Further, in the composite film sheet, the separation portion is a portion where the adhesive is not provided in advance, or a portion where the adhesive is provided but an adhesion reducing material that lowers the adhesiveness is also provided. The spacing portion can be formed using a suitable method.

  Further, the label body is a label body that is used by cutting the composite film sheet along the longitudinal direction with the dimension in the height direction of the label body as a pitch between the cutting positions. Spacing portions are collected at the upper and lower cutting positions. As a result, the central portion of the label body used for display or the like is sufficiently bonded, and a good wrinkle can be obtained without affecting the design when heat shrinking is applied.

  Further, since the labeled container is a labeled container in which the label body is provided, spaced portions are gathered alternately at each cutting position at the upper and lower cutting positions in the height direction of the label body. As a result, the central portion of the label body used for display or the like is sufficiently bonded, and a good wrinkle can be obtained without affecting the design when heat shrinking is applied. For example, in the case where the label body is a cylindrical body label, the adhesion between the first film and the second film, which are heat-shrinkable films in the cylindrical body label, in the body portion of the container can be made sufficient. When shrink-fitted, good wrinkles can be obtained without affecting the design.

  In addition, when a label body using a composite film sheet that adheres two films having different heat shrinkage rates is fixedly attached to a container and thermally contracted, wrinkles (皺In this case, according to the above configuration, a wrinkle having a good appearance can be obtained. For example, in the case where the label body is a cylindrical body, in the reduced diameter portion at the shoulder portion and the bottom portion of the container to which the cylindrical body label is attached, the interval between the adjacent line-shaped adhesive portions becomes narrow, and the wrinkle The pitch may be too dense and the swelling may be excessive. Moreover, in order to follow the above-mentioned reduced diameter part well, it is necessary to make the label body highly contracted. However, if the adhesive part is provided in a line shape, the film shrinkage is inhibited, and the container follows well. do not do.

  According to the above configuration, when there are reduced diameter portions on the top and bottom of the body portion, the separation portions can be alternately gathered there, so that it is possible to prevent the wrinkle pitch from becoming excessively dense, and the bonding portion and the bonding portion Since there is a gap between them, the shrinkage of the film is not hindered at that portion, and the wrinkle can be finished with good appearance following the reduced diameter portion.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Below, among the two films constituting the composite film sheet, one side will be described as a heat-shrinkable film and the other side as a non-heat-shrinkable film. Both films may be heat-shrinkable films. Further, the adhesion between the two films is described as using a so-called solvent-type adhesive, but other types may be used as long as the bonding method does not impair the characteristics of the heat-shrinkable film. . For example, a pressure-sensitive heat adhesive, a certain heat-sensitive adhesive, or an appropriate heat seal may be used in some cases. Moreover, although a cylindrical body label is formed from a composite film sheet, it is of course possible to form a label body such as a sheet label in a form other than the cylindrical body label. In addition, the dimensions and the like described below are exemplifications for explanation, and can be appropriately changed according to the dimensions of the label body and the shape and dimensions of the container to which the label body is mounted.

  Below, the same code | symbol is attached | subjected to the same element in all the drawings, and the overlapping description is abbreviate | omitted. In the description in the text, the symbols described before are used as necessary.

  FIG. 1 is a diagram schematically showing a state of the composite film sheet 10 in a partial cross-sectional view. The composite film sheet 10 is a long two-layer film sheet in which a cutting position is determined with a dimension in the height direction of the label body as a cutting pitch P along the longitudinal direction in order to form a plurality of label bodies. . The composite film sheet 10 is formed by bonding a first film 12 and a second film 14 to each other by a plurality of line-shaped adhesive portions 20 and 21. In FIG. 1, the composite film sheet 10 having a width that forms one label body is shown, but in practice, the composite film sheet 10 often has a width that allows a plurality of label bodies to be formed. Here, it is shown as a state after separating such a wide composite film sheet for each label body.

  The two films constituting the composite film sheet 10 have different thermal shrinkage rates, and the thermal shrinkage rate of the film on one side is larger than the thermal shrinkage rate of the film on the other side. As described above, when films having different heat shrinkage rates are bonded to each other at a line-shaped adhesive portion, fixed to a container or the like, and thermally contracted by heating or the like, the film on one side is large between adjacent line-shaped adhesive portions. Shrink, and the other film does not shrink much. As a result, the film on one side swells in a bowl shape between adjacent line-shaped adhesive portions, and is repeated between a plurality of line-shaped adhesive portions, so that it becomes a so-called wrinkle and has a design effect. It can be a body.

  Thus, by forming a composite film sheet using two films having different heat shrinkage rates, a label body, a cylindrical body label, a container with a label, and the like having a wrinkle having a design effect can be created. . Here, among the two films having different heat shrinkage rates, either the heat shrinkage rate is larger or the heat shrinkage rate is smaller, which can be provided on the container side, Below, the 1st film 12 is made into a heat-shrinkable film, and the 2nd film 14 is demonstrated as a non-heat-shrinkable film. And as a label body, the 1st film 12 which is a heat-shrinkable film is arrange | positioned on the container side, and the 2nd film 14 which is a non-heat-shrinkable film is arrange | positioned on the outer side, ie, the front side which is a visual recognition side seeing from a user. I will mainly explain what I do.

  Here, the heat-shrinkable film is a film that is uniaxially stretched in the width direction and has a heat shrinkage rate in the width direction larger than that in the longitudinal direction. The width direction is the vertical direction on the paper surface of FIG. For example, the circumferential direction when the composite film sheet 10 is cut at the cutting position to form a cylindrical label having a height P is the width direction of the composite film sheet 10. The longitudinal direction is the left-right direction on the paper surface of FIG. 1, and is the direction that becomes the height direction when the label body is formed.

  The heat-shrinkable film used for the composite film sheet 10 is a variety of plastic films such as vinyl chloride, polypropylene, polycarbonate, polyethylene terephthalate, and polyvinylidene chloride, and shrinks at a large heat shrinkage rate in at least one direction by heating. Can be used. Such anisotropy of the heat shrinkage rate can be obtained by forming a film by a known method such as a T-die method or an inflation method and stretching the film. The stretching treatment can be performed at a temperature of 70 ° C. to 110 ° C., for example, about 2 to 8 times, preferably about 3 to 7 times in the width direction. The obtained film becomes a uniaxially stretched film or a biaxially stretched film slightly stretched in a direction perpendicular to the main stretch direction.

  The anisotropy of the heat shrinkage rate is, for example, a heat shrinkage rate in the width direction of 20% or more, preferably 40% or more, more preferably 60% when immersed in warm water at 100 ° C. for 10 seconds, and in the longitudinal direction. The one having a thermal shrinkage of about −2% to + 10%, preferably about 0% to 6% can be used. In addition, heat shrinkage rate = 100 (%) × [(original length in width direction or longitudinal direction) − (length after immersion in warm water in width direction or longitudinal direction)] / (original in width direction or longitudinal direction) Length).

  As the heat-shrinkable film, the plastic film may have a single-layer structure or a multi-layer structure. Moreover, any of transparent and opaque may be sufficient, and what provided various unevenness | corrugations, such as a hairline, a mat | matte, and embossing, on the surface may be used. The thickness of the heat-shrinkable film is preferably about 10 to 60 μm, and preferably about 25 to 50 μm.

  On the other hand, a non-heat-shrinkable film is a film that does not have directionality in the heat-shrinkage rate and has a smaller value than the heat-shrinkable film. The material and thickness of the non-heat-shrinkable film used for the composite film sheet 10 can be the same as those of the heat-shrinkable film used for the composite film sheet 10. Of course, among the materials of the heat-shrinkable film described above, a material different from the heat-shrinkable film may be used, or the thickness may be different from that of the heat-shrinkable film.

  The first film 12 and the second film 14 are two films constituting the composite film sheet 10. Here, when the composite film sheet 10 is formed, the first film 12 as the lower layer side in FIG. 1 is the first film 12, and the other film as the upper layer side with the line-shaped adhesive portions 20 and 21 sandwiched therebetween is the second film. As film 14. As described above, the thermal contraction rate of the first film 12 and the thermal contraction rate of the first film 14 are different. Here, the first film 12 is a heat-shrinkable film and the second film 14 is non-thermal. It is a shrinkable film.

  In the example of FIG. 1, the line-shaped adhesive portions 20 and 21 are portions of the adhesive that extend in the longitudinal direction on the first film 12 and are arranged at predetermined intervals in the width direction. The line-shaped adhesive portions 20 and 21 can be formed, for example, by applying an adhesive in a line shape with a constant width on the first film 12 by a roll coating method or the like. As the adhesive, it is possible to use a solvent-type adhesive or the like that becomes an adhesive only by drying a material containing a solvent and a resin. As a drying temperature, it can be about 60 degreeC, for example so that the characteristic of a heat-shrinkable film may not be impaired. The thickness of the adhesive layer can be, for example, about 3 μm to 10 μm. In addition, it is good also as what provides the linear adhesive parts 20 and 21 in the 2nd film 14 instead of providing in the 1st film 12. FIG.

  Between the adjoining line-shaped adhesive parts 20 and 21, it is an area | region where an adhesive agent is not arrange | positioned continuously in a longitudinal direction, and this can be called a non-adhesion part. In this region, since the first film 12 and the second film 14 are not bonded, the composite film sheet 10 is elongated in the longitudinal direction and many gaps run between the films. The relationship between the width of the line-shaped adhesive portions 20 and 21 and the width of the non-adhesive portion is that the width of the line-shaped adhesive portions 20 and 21 is about 0.5 mm to 10 mm, and the width of the non-adhesive portion is also about 0.5 mm to 10 mm. It can be. It is good also as the width | variety of the line-shaped adhesion parts 20 and 21 and the width | variety of a non-bonding part. For example, the width of the line-shaped adhesion portions 20 and 21 can be 1.5 mm, the width of the non-adhesion portion can be 1.5 mm, and the like.

  The line-shaped adhesive portions 20 and 21 have a length in the longitudinal direction shorter than the cutting pitch P. FIG. 2 is an enlarged view of the end portion of the line-shaped adhesive portion 20, but the length portion of 2S between the ends of the two line-shaped adhesive portions 20 adjacent in the longitudinal direction is The separation portion 22 where the adhesive is not partially provided. In that sense, 2S can be called a separation length. The part of the separation length 2S is a place where the first film 12 and the second film 14 are separated without being partially adhered in a longitudinal region which is originally an adhesion part. In addition, between the parts of the separation length 2S adjacent in the longitudinal direction, an adhesive is continuously provided to form the line-shaped adhesive part 20, and the first film 12 and the second film 14 are continuous in this part. And glued. Accordingly, the lengths of the line-shaped adhesive portions 20 are PS. Since the separation portion length 2S is appropriately set around the cutting position, there is no problem even if the cutting position is slightly shifted.

  As shown in FIG. 1, the separation portion 22 in the adjacent line-shaped adhesive portion 20 is disposed on one side of a cutting position that is disposed with a cutting pitch P therebetween. In FIG. 1, among the cutting positions at both ends of the cutting pitch P shown as one, it is arranged at the cutting position on the left side on the paper surface.

  The line-shaped adhesive part 21 adjacent to the line-shaped adhesive part 20 is similarly provided with a separation part 23, but the separation part 23 is arranged on the other side of the cutting position arranged with a cutting pitch P. In FIG. 1, among the cutting positions at both ends of the cutting pitch P shown as one, they are arranged at the cutting positions on the right side on the paper surface.

  FIG. 3 shows a cross-sectional view at a cutting position on one side. In addition, illustration of the 2nd film 14 is abbreviate | omitted and a mode that the suitable printing layer 16 for a display is provided on the 1st film 14 is shown. Here, a state in which three line-shaped adhesive portions are provided on the display print layer, that is, on the surface in direct contact with the second film 14 is illustrated. Of course, the display printing layer may be provided on the opposite side of the film, or may be provided on both sides.

  In FIG. 3, the line-shaped adhesive portion 20 shown in the center is just the separation portion 22, and is shown in the cross-sectional view as having no adhesive. Since the left and right line-shaped adhesive portions 21 do not have the separation portion 23 at the cutting position on one side, they are shown in the sectional view as having an adhesive. On the other hand, at the cutting position on the other side, on the contrary, there is no adhesive in the line-shaped adhesive portion 21 and there is no separating portion 23, and there is an adhesive in the line-shaped adhesive portion 20 and there is no separating portion 22.

  That is, the separation portions 22 and 23 are provided for each of the two line-shaped adhesive portions 20 and 21 at every two cutting positions along the longitudinal direction, and between the adjacent line-shaped adhesive portions 20 and 21. In between, they are provided at different cutting positions along the longitudinal direction.

  The separation length 2S, which is the length of the separation portions 22 and 23, is attached to the cylindrical body label 30 and the tubular body label 30 described later, along with the widths of the line-shaped adhesion portions 20 and 21 and the width of the non-adhesion portion. It is preferable to set appropriately according to the form of the container 40 to be used. For example, the width of the line-shaped adhesive portions 20 and 21 and the non-adhesive portion 2S are within the above ranges, and the separation length 2S can be about 4 mm to 30 mm.

  As described above, the separation portions 22 and 23 are regions where the adhesive is not partially disposed in the longitudinal direction of the line-shaped adhesion portions 20 and 21, and thus can be referred to as an adhesive removal region. The separating portions 22 and 23 are provided so as not to be partially bonded when the first film 12 and the second film 14 to be stacked are bonded in a line shape. You may make it reduce the adhesiveness while applying.

  4 and 5 are diagrams showing an example of a structure in which the adhesiveness is partially lowered at the cutting position while the adhesive is continuously provided in a line shape. These figures correspond to FIG. 3 and are sectional views at a cutting position on one side.

  In FIG. 4, after the adhesive is continuously formed in a line shape along the longitudinal direction of the first film, a silicon resin 24 is provided at portions corresponding to the separation portions 22 and 23 at the cutting position. . By covering a part of the continuous line-shaped adhesive portion 20 with the silicon resin 24, it is possible to prevent the first film 12 and the second film 14 from being bonded to each other. Other than the silicon resin 24, a film layer made of a material that lowers the adhesiveness may be provided. In FIG. 4, the silicon resin 24 is directly provided on the adhesive of the film 12, but a silicon resin or the like may be previously applied to the opposing film 14 together with the display print layer 16.

  FIG. 5 shows that the adhesive is formed in a continuous line shape along the longitudinal direction of the first film, and that additive particles such as wax are provided on the portions corresponding to the separating portions 22 and 23 at the cutting position. 26 is arranged. The size of the additive particle 26 is larger than the thickness of the adhesive layer. For example, when the thickness of the adhesive layer is several μm, the size of the additive particles 26 is preferably about 10 μm. Such a slippery additive particle 26 or an adhesive layer having low adhesion formed by mixing the additive particle 26 may be referred to as a medium or the like, but FIG. This is used for the separation portions 22 and 23. Even in the case of FIG. 5, as in the case of FIG. 4, medium may be applied to the opposing film 14 in advance.

  The operation of the composite film sheet 10 having such a configuration will be described. The composite film sheet 10 is formed by adhering the first film 12 and the second film 14 to each other by the line-shaped adhesive portions 20 and 21 as described above. And also in subsequent processes, for example, processes such as printing, cutting along the longitudinal direction, and forming into a cylinder, the composite film sheet 10 is fed out in the longitudinal direction while being sandwiched by the rolls, and is processed. In this subsequent process, when the composite film sheet 10 moves while being sandwiched by the rolls, the slight air present in the non-adhesive portion between the first film 12 and the second film 14 moves with the composite film sheet. 10 is pushed forward. At this time, since the separation portions 22 and 23 are provided at the cutting pitch P or an interval twice that of the cutting pitch P, the moving air sequentially moves to the adjacent non-adhesive portions and is discharged from both side surfaces of the composite film sheet 10 to the outside. Is done.

  The state of the air flow is indicated by arrows in FIG. In the absence of the separation portions 22, 23, the air present in the non-bonded portion is only pushed forward in the stripe-shaped narrow gap, and the amount of air gradually accumulates, and the composite film sheet 10. Swells up at the non-bonded portion, and in some cases, peeling of the bond at the line-shaped bonded portion may occur. By providing the separation portions 22 and 23, air can be appropriately removed from both side surfaces of the composite film sheet 10, and adhesion peeling and the like can be prevented.

  Next, FIG. 6 is a figure which shows the mode of the cylindrical body label 30 as a label body using the composite film sheet 10 formed in this way. The cylindrical body label 30 can be obtained by joining both ends along the longitudinal direction of the composite film sheet 10 into a cylindrical shape, and cutting it at a cutting pitch P at a cutting position. Here, a front view shown as a partial cross-sectional view is shown.

  When the cylindrical body label 30 is formed in a cylindrical shape, the cylindrical inner side is the first film 12 that is a heat-shrinkable film. By doing in this way, when attached to a container, the cylindrical inner peripheral side is in close contact with the surface of the container, and unevenness due to the shrinkage difference appears favorably on the cylindrical surface side. Of course, it is good also considering the 1st film 12 as a cylindrical outer side according to a use.

  Since the cylindrical body label 30 is formed by forming the composite film sheet 10 into a cylindrical shape, the width direction described in FIG. 1 is the cylindrical circumferential direction. The cutting pitch P between the cutting positions is a cylindrical height, and the longitudinal direction described in FIG. 1 is the height direction. And the separation | spacing parts 22 and 23 and the line-shaped adhesion parts 20 and 21 are alternately arrange | positioned at the both ends of a height direction, respectively. That is, the line-shaped adhesive portions 21 and the separating portions 22 are alternately arranged at one end portion on the left side of the paper surface of FIG. 6, and the line-shaped adhesive portions 20 and the separating portion are disposed at the other end portion on the right side of the paper surface. 23 are arranged alternately.

  Thus, in the cylindrical body label 30, since the separation | spacing parts 22 and 23 are collected and arrange | positioned at the both ends of a height direction, in the center part of the height direction used for a display etc., a 1st film 12 and the second film 14 are firmly bonded. As a result, the influence on the design and the like due to the provision of the separation portions 22 and 23 can be reduced.

  FIG. 7 is a diagram illustrating a state of the container 40 provided with the cylindrical body label. Here, a cylindrical body label 31 thermally contracted by heating is provided in a container 34 having a reduced diameter portion 32 whose outer shape gradually decreases toward the cap at the upper side of the body portion. The cylindrical body label 31 covers a part of the bottom part of the container 34 and covers a part of the reduced diameter part 32. That is, here, the separating portion 22 is set so as to come to the reduced diameter portion 32 of the container 34, and the separating portion 23 is collected at the bottom of the container 34. In this case, the separation length may be adjusted to the height dimension of the region of the reduced diameter portion 32. In the example of FIG. 7, the size of the reduced diameter portion 32 is set to S that is ½ of the separation length.

  By doing in this way, the 1st film 12 and the 2nd film 14 can be adhere | attached firmly, without providing the separation parts 22 and 23 in the center part where the display of the trunk | drum of the container 34, etc. is performed. Thereby, the influence of the separation parts 22 and 23 on the design or the like of the container 34 can be reduced. Although not shown here, the cylindrical body label 31 may be provided with opening means such as perforations.

  Further, the appearance of the cylindrical body label 31 in the reduced diameter portion 32 can also be improved. That is, when the tubular body label 30 using the composite film sheet 10 of the first film 12 that is a heat-shrinkable film and the second film 14 that is a non-heat-shrinkable film is attached to a container and thermally shrunk, Since the thermal contraction rate of the second film 14 is smaller than the thermal contraction rate of the first film 12, the portion of the second film 14 swells at the non-adhesive part between the line-like adhesive parts 20 and 21. Thereby, a wrinkle can be formed and used for a design or the like. However, in the reduced diameter portion of the shoulder portion of the container 34 and the portion that moves to the bottom portion, the interval between adjacent line-shaped adhesive portions becomes narrow, the wrinkle pitch becomes excessively dense, and the swelling is excessively increased. There is. In addition, since the shrinkage is inhibited by the adhesive portion, the followability to the reduced diameter portion is deteriorated, the float is generated, and the appearance is deteriorated.

  As shown in FIG. 7, the separation portions 22 and 23 are collected and alternately arranged at the reduced diameter portion 32 and the bottom portion, so that the wrinkle pitch can be suppressed from becoming excessively dense, and the separation portions 22 and 23 are provided. In this way, the followability can be improved and the wrinkle can be finished with a good appearance. This will be described with reference to FIGS. 8A and 8B which are sectional views of the reduced diameter portion 32. FIG.

  FIG. 8B is a diagram showing a case of a conventional example in which the separation portion 22 is not provided in the reduced diameter portion 32. Here, the line-shaped adhesive portions 20 and 21 are alternately arranged in the circumferential direction, and the first film 12 and the second film 14 are bonded at the portions, but the non-between the line-shaped adhesive portions 20 and 21 is not. In the bonding portion, the second film 14 is not bonded to the first film 12, but swells to the outside of the container 34 due to the difference in the thermal contraction rate in the circumferential direction, and a so-called wrinkle is formed.

  Here, since the pitch of the circumferential arrangement of the line-shaped adhesive portions 20 and 21 is denser than that of the barrel portion of the container 34, the pitch of the wrinkle is also denser than that of the barrel portion. Correspondingly, wrinkle bulge rises. Since the degree of density and the degree of swelling increase as the degree of diameter reduction increases, depending on circumstances, the pitch and the swelling may become excessive. And the peeling of the adhesion | attachment by the line-shaped adhesion parts 20 and 21 may arise. Moreover, since shrinkage | contraction is inhibited by the adhesion part, the followable | trackability to a diameter-reduced part worsens. Thus, if an excessive pitch, excessive swelling, shrinkage failure, adhesion peeling, or the like occurs, the design effect of the wrinkle may be impaired.

  FIG. 8A is a diagram illustrating a case where the separation portion 22 is provided in the reduced diameter portion 32. Here, only the line-shaped adhesive portion 21 appears, and a separation portion 22 is provided at a position corresponding to the other line-shaped adhesive portion 20, so that the interval between adjacent line-shaped adhesive portions is as shown in FIG. It can be taken widely compared to b). Considering the original non-bonded portion between the line-shaped bonded portions 20 and 21, the interval between adjacent line-shaped bonded portions is two to three times wider than that in the case of FIG. can do. Thereby, it can suppress that the pitch of the wrinkle in the reduced diameter part 32 becomes small too much, and can suppress that the swelling of a wrinkle becomes excessive. Further, peeling of the adhesion can be prevented, and furthermore, since the gap between the adhesion portions 21 in the reduced diameter portion is wide, the film is thermally contracted in the portion and follows the container well, so that the appearance of the wrinkle is improved.

  In the reduced diameter portion 32, the interval between adjacent line-shaped adhesive portions 21 is wider in the body portion and narrower on the cap side at the tip, so the length S of the separation portion 22 is not necessarily the height of the reduced diameter portion 32. It does not have to be the same as the dimension in the direction, and can be set appropriately according to the degree of diameter reduction.

  As described above, since the adhesive portions 21 and the separation portions 22 are alternately arranged at the end of the label, a good wrinkle tone can be expressed even in the reduced diameter portion, and the container can be made to follow the film well. Become. In addition, when there are few space | interval parts 22, a wrinkle will excessively bulge and shrinkage | contraction will arise, conversely, when there are too many space | interval parts 22, the space | interval of the adhesion part 21 will be too wide, a film will turn over, and it is favorable. The wrinkle tone is not obtained and the appearance is poor.

  In the above description, the heat shrink film is described as being on the container 34 side. However, the same effect can be obtained when the non-heat shrink film is the container side and the front side of the packaging is the heat shrink film. In addition, when providing the part which diameter-reduces in a trunk | drum etc. partially, a separation part can also be provided in the place corresponded to the location.
