Description

  The present invention relates to a packaging structure including a plurality of packaging bodies bound to each other.

  Conventionally, as a method for binding articles such as a plurality of containers, there is a method of wrapping and binding a plurality of articles that are hard and not deformed by a packaging material made of a shrink film (see Patent Document 1). There is also a method of binding a plurality of articles that are hard and do not deform using an adhesive sheet. In addition, when two cocoon flake bottles are bound, a sleeve-shaped shrink film may be used.

JP 2006-44797 A

  By the way, when a plurality of easily deformable containers, for example, a plurality of soft wrapping materials filled with contents, are bound by applying a binding force, the containers are easily deformed by the binding force. When the container is deformed, the aesthetic appearance is impaired, the label design is distorted, and it may be difficult to maintain a good binding state.

  An object of the present invention is to provide a packaging structure in which a packaging body filled with contents in a pouch container is not easily deformed and a good binding state of a plurality of packaging bodies can be easily maintained.

  The packaging structure according to the present invention includes a pair of trunk sheets connected to both side edges in the width direction, a bottom sheet joined to the lower ends of the pair of trunk sheets, and upper ends of the pair of trunk sheets. A collective package comprising a plurality of packages filled with contents in a pouch container having a spout attached to the top sheet, and the collective package And the adjacent packaging bodies are overlapped so that at least a part of the sheet surface of each of the trunk sheet is in contact with each other.

  According to the present invention, the pouch container has the top sheet and the bottom sheet on both the upper side and the lower side of the pair of body sheets joined to the edges in the width direction. The packaging body filled with the contents approaches the size of the size cylinder, and the shape of the cut surface perpendicular to the height direction does not change much in the height direction as compared with the packaging body without the top sheet or the bottom sheet. Therefore, a packaging structure in which a plurality of packaging bodies having such shapes are bound so as to overlap the body sheet can increase the adhesion of the body sheet, so that the binding state is good and the stability of the binding state is improved. Will improve. In addition, since a good binding state can be maintained, even when the packaging structure is required to be upright, it is possible to stabilize the upright posture in the binding state by simply aligning the positions in the height direction at the lower ends of multiple packages. Easy to do.

  Moreover, in this invention, the said binding body may consist of a cyclic | annular strip | belt-shaped member surrounding the said assembly package.

  In this case, since the collective package is surrounded by the annular belt-like member, the integrated state of the collective package can be maintained more stably.

  Moreover, in this invention, the said cyclic | annular strip | belt-shaped member may have the shrinkage | contraction part shrink | contracted with a heat | fever at least one part of the circumferential direction.

  In this case, since a contraction part that shrinks by heat is provided in a part of the circumferential direction in the annular belt-like member, the annular belt-like member having a large diameter before applying heat is arranged around the assembly package, and then By narrowing the diameter of the annular belt-shaped member only by applying heat, the collective package can be easily and appropriately fastened by the annular belt-shaped member.

  Further, in the present invention, when the annular belt-like member has a contraction part that shrinks by heat in at least a part in the circumferential direction, the annular belt-like member does not shrink by heat in a part of the circumferential direction. You may have a part.

  In this case, since the annular belt-shaped member has the contraction part and the non-contraction part, the collective package can be tightened with an appropriate tightening force. Therefore, a plurality of pouch containers filled with the contents can be surely bound, and the appearance of the bound state can be made relatively excellent.

  Moreover, in this invention, when the said cyclic | annular strip | belt-shaped member has the said shrinkage | contraction part and the said non-shrink part, the said assembly package is piled up so that the width direction center part of each said said trunk | drum sheet | seat may contact. Two package bodies to be formed, and there is a recessed space around the side end of the contact portion of the two package bodies, and at least a part of the contraction section may be arranged to face the recessed space. .

  In this case, the annular belt-shaped member is at least a portion facing the recessed space formed in the vicinity of the side end of the contact portion of the two packaging bodies stacked so that the center portions in the width direction of the body sheet are in contact with each other. Some contract. Therefore, since at least a part of the annular belt-shaped member is contracted at a position where the degree of freedom of contraction is larger than the concave space, the wrinkle is not easily moved to the annular belt-shaped member, and the aesthetic appearance of the packaging structure is circular. It can suppress that it is damaged with the wrinkle of the strip-shaped member.

  Moreover, in this invention, the said cyclic | annular strip | belt-shaped member may cover the said lower end part of the said trunk | drum sheet | seat in the said collective package body at least.

  If the central part in the height direction of the collective package is tightened with an annular belt-like member, a part of the contents move to the lower side of the pouch container, so that the bottom side of the collective package is expanded in the packaging structure. There is a risk of an unstable shape. On the other hand, when the lower end portion side of the collective package is tightened by the annular belt-like member, a part of the contents can be moved to the upper side of the unfastened pouch container. Therefore, the bottom structure of the collective package is a structure in which a plurality of packages are in close contact, and the bottom shape of the collective package is a cylindrical shape in which the shape of the cut surface perpendicular to the height direction does not change much in the height direction. Get closer to. Therefore, the adhesiveness of the lower side of a collective package can be improved, and a favorable restraint state can be constructed on the lower side of the packaging structure. Furthermore, when the height direction positions of the bottoms of the plurality of packaging bodies are aligned and the lower end portions of the assembly packaging bodies are placed on a horizontal surface, the lower ends of the assembly packaging bodies are tightened. It is possible to prevent the contents from being biased downward by moving downward. Therefore, when uprightness of the packaging structure is required, a good restraint state can be established on the lower side of the packaging structure, and the packaging structure can be stably raised.

  Moreover, in this invention, the said cyclic | annular strip | belt-shaped member may cover the said bottom sheet side rather than the end by the side of the said top | upper surface sheet in the junction part of the both-sides edge of the said trunk | drum sheet | seat.

  In this case, the annular belt-like member is attached to the bottom side with respect to the end on the top sheet side in the joint portion of the side edge of the trunk sheet, and does not cover the top sheet. Therefore, distortion of the top surface sheet can be suppressed, and it is possible to suppress wrinkles on the annular member due to local force from the top surface sheet, thereby suppressing deterioration of the aesthetic appearance of the packaging structure.

  Moreover, in this invention, you may provide the tack sheet stuck across the surface of the said binding body, and the surface of the said trunk | drum sheet | seat.

  In this case, it is possible to prevent the bundle from coming off. In particular, when a bundle that binds the collective package in a non-adhered state is used, for example, the bundle is an annular belt-like member that has a contracted portion and binds the collective package as the contracted portion contracts. In the case where the bundled body is an annular belt-like member that binds the collective package body by stretching force, it is preferable to have the tack sheet.

  In the present invention, the binding body has a perforation extending in a height direction of the collective packaging body at a portion facing the recessed space, and the binding body has a distance of 30 mm or less with respect to the perforation. You may provide the tack sheet stuck across the surface of the body and the surface of the said trunk | drum sheet | seat.

  In this case, since the tack sheet is affixed at a position where the distance to the perforation is 30 mm or less, the peripheral portion of the perforation is fixed by the tack sheet, so when attempting to cut the perforation, Is easily cut.

  According to the packaging structure of the present invention, the packaging body filled with the contents in the pouch container is not easily deformed, and the upright posture in a bundled state of the plurality of packaging bodies can be stably maintained.

  FIG. 1 is a perspective view of a packaging structure 80 according to an embodiment of the present invention.

  The packaging structure 80 includes a collective package 50 configured by assembling two packages 10 and a bundle 60 that binds the collective package 50 together. The two package bodies 10 are aligned in a line. The package 10 includes a content and a pouch container 40 that is inflated by filling the content. Although the contents are not particularly limited, for example, the contents include various daily care products such as shampoos, rinses, treatments, and detergents, and beverages such as sports drinks. The content is not limited to a liquid, and may be a viscous material or a powdery material. The content is preferably fluid, such as liquid, jelly-like material, viscous material, powdery material, and granular material.

  As shown in FIG. 1, the binding body 60 is configured by an annular belt-like member that surrounds the collective packaging body 50. By being fastened to the band-like bundle 60, the collective package 50 is integrated and does not separate. Hereinafter, the pouch container 40 will be described in detail with reference to FIG. 2, and the binding body 60 will be described in detail with reference to FIG. Then, after that, the packaging structure 80 will be described in detail again, and for example, the structure of the assembly package 50 and the fastening of the binding body 60 to the assembly package 50 will be described in detail.

  FIG. 2 is a perspective view of the package 10. As shown in FIG. 2, the pouch container 40 of the package 10 is formed by stacking four sheet materials and joining them with a seal portion such as the side seal portion 22.

  The pouch container 40 includes a top sheet 11 and a back sheet 12 (a pair of trunk sheets), a bottom sheet 13, and a top sheet 14. The top sheet 11 and the back sheet 12 are sheet materials that constitute the front and back portions of the container, respectively. The top sheet 14 is inserted between the top sheet 11 and the back sheet 12 on the upper end side, and the bottom sheet 13 is inserted between the top sheet 11 and the back sheet 12 on the lower end side. The pouch container 40 can be self-supported by developing the bottom sheet 13 by filling the contents. The top sheet 14 is a sheet material that constitutes a top surface portion having a spread of the container. Further, the bottom sheet 13 is a sheet material that forms a bottom part having a spread of the container.

  The pouch container 40 is inserted between the top sheet 11 and the back sheet 12 that are overlapped, with the top sheet 14 inserted from the upper end side and the bottom sheet 13 inserted from the lower end side. The edges are joined together by a seal portion, and the filling portion 17 which is a container internal space filled with the contents is sealed. The upper end of the filling part 17 is sealed by joining the top sheet 14 to the upper end part of the top sheet 11 and the back sheet 12, and the bottom sheet 13 is sealed by the bottom sheet 13 of the top sheet 11 and the back sheet 12. It is sealed by being joined to the lower end.

  The top sheet 11 and the back sheet 12 both have a substantially rectangular shape that extends slightly in the vertical direction and has a chamfered corner on the upper end side. The top sheet 14 has a substantially hexagonal shape, and is joined to the upper ends of the top sheet 11 and the back sheet 12. The top sheet 14 is not limited to a substantially hexagonal shape, and may be, for example, other polygonal shapes such as a quadrangle and an octagon, or a shape such as a circle, an ellipse, and a rhombus. There may be. On the other hand, the bottom sheet 13 has a substantially rectangular shape. The bottom sheet 13 can be provided, for example, in a range of about 1/5 or less of the top and bottom lengths of the top sheet 11 and the like from the lower ends of the top sheet 11 and the back sheet 12.

  The sheet material which forms each sheet 11-14 is a sheet-like member which constitutes the wall part of pouch container 40, and is usually constituted from a resin film. The resin film constituting the sheet material is required to have basic performance as a package, such as impact resistance, wear resistance, and heat resistance. The thickness of the sheet material is, for example, 20 μm to 300 μm, preferably 30 μm to 200 μm. Further, since the seal portion is usually formed by heat sealing, the sheet material is also required to have heat sealing properties. As the sheet material, a multilayer sheet material having a base film layer and a sealant layer that imparts heat sealability is suitable, and when high gas barrier properties are required, the sheet material is provided between the base film layer and the sealant layer. It is preferable to provide a gas barrier layer.

  Here, constituent materials of the base film layer, the sealant layer, and the gas barrier layer are exemplified. In addition, lamination | stacking of these each layer can be performed by the conventional lamination method, for example, the dry lamination by an adhesive agent, the heat lamination which adhere | attaches with a heat | fever by pinching | interposing a heat bonding layer.

  Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP)), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), and A stretched or unstretched film of one layer or two or more layers composed of polyethersulfone (PES) or the like can be exemplified. The thickness of the base film layer is, for example, 10 μm to 200 μm, preferably 10 μm to 100 μm.

  The films constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film can be exemplified. The thickness of the sealant layer is, for example, 10 μm to 200 μm, preferably 20 μm to 180 μm.

  The gas barrier layer may be a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or any synthetic resin film (for example, a base film layer). ), And a film obtained by vapor-depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica. The thickness of the gas barrier layer is, for example, 0.1 μm to 20 μm, preferably 0.2 μm to 10 μm.

  The seal part is preferably formed by heat sealing. The seal part by heat sealing can be formed by superposing and thermocompression bonding so that the sealant layer of each sheet material is inside the container. The pouch container 40 includes a top seal part 20, a bottom seal part 21, and a side seal part 22 as the seal part. The top seal portion 20 is a seal portion formed in a frame shape having a substantially hexagonal shape at the edge of the top surface sheet 14, and the outer peripheral edge of the top surface sheet 14 and the upper end portions of the topsheet 11 and the backsheet 12. Are joined together. The bottom seal portion 21 is a seal portion formed at the edge of the bottom sheet 13, and is formed by joining the bottom sheet 13, the topsheet 11, and the backsheet 12.

  The side seal portions 22 are formed at both ends in the width direction by directly joining the width direction edges of the top sheet 11 and the back sheet 12. The side seal part 22 is an edge seal part for sealing the filling part 17 like other seal parts. The side seal part 22 extends along the vertical direction. The side seal portion 22 is formed as wide portions 28 and 29 at the lower end portion and the upper end portion thereof, while the intermediate portion in the vertical direction is formed as a narrow portion having a narrow width.

  In the pouch container 40, a plug 30 for filling and taking out the contents is provided at the center of the top sheet 14. The plug 30 includes a spout 31 that is fixed to the top sheet 14 and a cap 32 that is screwed into a screw portion formed on the outer periphery of the spout 31.

  The spout 31 has a cylindrical portion 31a that protrudes outward from the top sheet 14 and a flange portion 31b that is integrally formed at the end of the cylindrical portion 31a. The flange portion 31b has a substantially rectangular shape, and is attached to the inner surface of the top sheet 14 (that is, the surface on the filling portion 17 side) by, for example, heat sealing. The shape of the flange portion 31b is not limited to a substantially rectangular shape, and may be other shapes such as a circle, an ellipse, an oval, and a polygon.

  As in the example shown in FIG. 2, the flange portion 31 b of the spout 31 is preferably substantially rectangular, and further includes a side 31 b-1 that is substantially parallel to the width direction and a side 31 b-2 that is substantially parallel to the depth direction. preferable. Further, the length of the flange portion in the depth direction is preferably 70% to 100% of the depth length of the top surface sheet excluding the top surface seal portion, and further, the length of the top surface sheet excluding the top surface seal portion. It is preferable that the length is substantially the same as the depth length. When the flange portion of the spout is configured by a side substantially parallel to the width direction and a side substantially parallel to the depth direction to have a substantially rectangular shape, the flange portion has a predetermined length in the depth direction. In the top surface portion, a state in which the top sheet and the back sheet are separated can be secured. Therefore, even if there is a portion where there is no content on the upper end side in a state where the packaging body is erected, a top surface portion having a predetermined interval can be secured between the top sheet and the back sheet.

  1 and 2, in the collective package 50, the height positions of the flange portions 31b of the spouts 30 of the respective packages 10 are substantially the same. Since the flange portion of the spout has a substantially rectangular shape composed of sides that are substantially parallel to the width direction and sides that are substantially parallel to the depth direction, in the collective package 50, the two adjacent packages 10 are mutually connected. Sides substantially parallel to the width direction of the flange portions 31b of the trunk portion sheets 11 and 12 are in contact with each other. Further, in the collective package 50, the adjacent body sheet 11, 12 in the two adjacent packages 10 are in contact with the sheet surface portions that are substantially parallel across the flange portion 31 b of the spout 30. In the form of FIG. 1, the sheet surface of the back sheet 12 of one package 10 and the top sheet 11 of the other package 10 is in contact with the width direction center of the package 10. From this, in the collective package 50, the two packages 10 can be bound more closely, and the bound state can be stabilized.

  Referring to FIG. 2 again, the bottom sheet 13 has triangular unsealed portions 16 formed at both ends in the width direction, and a semicircular notch is formed at the width direction end corresponding to the unsealed portion 16. 18 is formed. The top sheet 11 and the back sheet 12 are directly joined by a point seal through the notch 18 of the bottom sheet 13.

  When the filling portion 17 of the pouch container 40 is filled with the contents according to this sealing form, the bottom sheet 13 is unfolded so that the top sheet 11 and the back sheet 12 are separated from each other, and the body is inflated. . And the package 10 which consists of the pouch container 40 and the content with which it was filled has self-supporting property, ie, standing property. As described above, the top sheet 14 has a substantially hexagonal shape, while the bottom sheet 13 has a substantially rectangular shape, and the shapes of both sheets 13 and 14 are different. In addition, the shape of the upper part of the package 10 is different from the shape of the bottom of the package 10 in a state where the package 10 in which the pouch container 40 is expanded by filling the contents is upright. However, as in this embodiment, when the packaging body 10 is standing upright, the existing area in plan view when the packaging body 10 is viewed from the spout 31 side is such that the packaging body 10 is on the bottom sheet 13 side. If it is substantially the same as the existing area in the plan view of the bottom when viewed from above, it is preferable because the upright posture can be stabilized.

  The area of the top sheet 14 is preferably 0.5 to 1.5 times the area of the bottom sheet 13 and more preferably 0.7 to 1.3 times. In addition, the length of the top sheet 14 in the depth direction is preferably 0.5 to 1.5 times the length of the bottom sheet 13 in the depth direction, and more preferably 0.7 to 1.3 times. Moreover, it is preferable that the length of the width direction of the top sheet 14 is 0.5 to 1.5 times the length of the width direction of the bottom sheet 13, and it is 0.7 to 1.3 times. More preferred.

  The bottom seal portion 21 is formed by joining the inner surfaces of the pair of body portion sheets 11 and 12 and the inner surface of the bottom sheet 13. More specifically, the bottom seal portion 21 has a lower end seal portion 21 a in which the inner surfaces of the lower end portions of the pair of body portion sheets 11 and 12 and the peripheral edge of the bottom portion sheet 13 are joined. Further, the bottom seal portion 21 is inclined upward from the lower end seal portion 21a in the vicinity of the center portion in the width direction of the package body 10 toward both ends in the width direction, and both ends in the width direction (connected to the side seals 22). The inclined seal portion 21b is formed. The lower end seal portion 21a and the inclined seal portion 21b are not sealed, and the aforementioned triangular unsealed portion 16 is formed.

  With reference to FIGS. 1 and 2, in the collective package 50, each sheet surface on which two adjacent packages 10 overlap and contact each other is formed by a region surrounded by the following two seal portions. That is, a bottom seal near the center in the width direction at the lower end portion of the trunk sheet, and a lower seal portion formed between the inclined seal portions and an upper end portion of the trunk sheet in parallel to the width direction. It is formed in a region surrounded by the top seal portion in the vicinity of the extending central portion in the width direction.

  Referring to FIG. 2 again, the lower seal portion 21a on the front side formed by the top sheet 11 and the bottom sheet 13 and the bottom seal portion 21a on the back side formed by the back sheet 12 and the bottom sheet 13 are as follows. At the both ends in the width direction of the package body, they are in contact with or close to each other, and the lower end seal portion 21a is formed in a substantially annular shape to form the bottom portion of the package body. In the present embodiment, the unsealed portion 16 is point-sealed at both ends in the width direction of the package, so that the lower end seal portion 21a on the front side and the lower end seal portion 21a on the back side are at both ends in the width direction of the package. A contact or proximity state is formed.

  The substantially annular lower end seal portion 21a is substantially located on the same plane orthogonal to the axial direction. With this configuration, when the packaging body 10 is erected, the lower end seal portion 21a comes into contact with the floor surface, and the packaging body 10 can stably maintain the standing state.

  The bottom sheet 13 forms a depression that is most recessed on the top sheet 14 side at one end and the other end in the width direction of the package 10 that is located on the side seal part 22 side. This recess is deepest at the upper end of the bottom sheet 13 that is joined to the boundary between the pair of body sheets 11 and 12 and is located closest to the top sheet 14. The said hollow has the shape where the location located in the upper end sharpened to the top | upper surface sheet | seat 14 side. The bottom sheet 13 swells downward from one end and the other end in the width direction toward the center, and swells to the lower side opposite to the top sheet 14, and from the one end and the other end in the depth direction toward the center. Accordingly, the bottom seal portion 21 swells downward from the upper end on the top sheet 14 side. In the state filled with the contents, the annular lower end seal portion 21a of the bottom seal portion 21 and the portion located at the substantially central portion in both the width direction and the depth direction in the bottom sheet 13 come into contact with the ground, The package 10 stands upright. However, the package 10 may be a raised bottom that comes into contact with the floor surface only by the lower end seal portion 21a. In this case, the bottom sheet 13 other than the region where the lower end seal portion 21a is formed is not in contact with the floor surface.

  As shown in FIG. 2, the bottom sheet 13 and the top sheet 14 have substantially the same size in a form in which the body portion swells. For example, from the side seal part 22 on one side to the side seal part 22 on the other side. The distance is almost the same. From this, the independence of the package 10 is stabilized. The contents can be filled from the spout 31. By providing the top sheet 14 in the pouch container 40, the packaging body 10 swells at the top as shown in FIG. 2 and has a cylindrical shape, which looks like a bottle.

  In the present embodiment, a case has been described in which a pair of body sheets 11, 12, a bottom sheet 13, and a top sheet 14 are configured by four different sheets. The torso sheet, the bottom sheet and the top sheet may be configured to form a pair of torso sheets, the bottom sheet and the top sheet by folding or joining a number of sheets other than four. Also good.

  FIG. 3 is a perspective view showing the bundled body 60 before surrounding the collective package 50, and FIG. 4 is a schematic plan view of the bundle 60 before surrounding the collective package 50.

  The bundled body 60 is made of a band-shaped film. The bundled body 60 has a non-shrinkable portion 61 that does not shrink due to heat in a first portion in the circumferential direction, and a shrinkable portion 62 that shrinks due to heat in a second portion in the circumferential direction. As shown in FIG. 4, the bundled body 60 is composed of a sleeve-like heat-shrinkable film 65 and a non-annular non-heat-shrinkable film 66 fixed to an inner circumferential part of the heat-shrinkable film 65 with an adhesive. Composed. Here, the sleeve-like heat-shrinkable film 65 is configured by bonding one end portion and the other end portion in the extending direction of the belt-like heat-shrinkable film with an adhesive portion 68. The adhesive portion 68 is formed, for example, by welding the one end and the other end with a solvent. In this example, the non-shrinkable portion 61 is a non-shrinkable film in the heat-shrinkable film 65 indicated by an arrow A in FIG. It is comprised by the circumferential direction part to which the heat-shrinkable film 66 is adhere | attached. Moreover, the contraction part 62 is comprised by the other circumferential direction part in the binding body 60 shown by the arrow B in FIG.

  Examples of the heat-shrinkable film 65 include polyester resins such as polyethylene terephthalate resins and polylactic acid resins, polyolefin resins such as polyethylene resins and polypropylene resins, polystyrene resins, polyvinyl chloride resins, and polyamide resins. It is comprised by the 1 type selected from thermoplastic resins, such as these, or a 2 or more types of mixture. Of these materials, the heat-shrinkable film 65 is preferably a polyester resin, a polyolefin resin, or a polystyrene resin, and more preferably a polyester resin or a polyolefin resin, from the viewpoint of shrink characteristics. The heat-shrinkable film 65 may be a single layer film or a multilayer film having a plurality of layers. In the case of a multilayer film, you may have a heat seal layer as a layer which comprises a back surface.

  On the other hand, the non-heat-shrinkable film 66 is preferably a stretched film or a non-stretched film such as a polyester resin such as a polyethylene terephthalate resin or a polylactic acid resin, or a polyolefin resin such as a polyethylene resin or a polypropylene resin. Composed. The non-heat-shrinkable film 66 is bonded to the heat-shrinkable film 65 with a dry laminate adhesive. Note that the non-heat-shrinkable film 66 may be made of paper, synthetic paper, non-woven fabric, or foam sheet instead of the above-described film. Further, as the non-heat-shrinkable film 66, a non-heat-shrinkable film (tack sheet) with a pressure sensitive adhesive may be used. In this case, the non-heat-shrinkable film 66 is bonded to the heat-shrinkable film 65 with a pressure-sensitive adhesive without using the dry laminate adhesive.

  Referring to FIG. 4, the phase range in the circumferential direction of the bundled body occupied by the non-contracted portion 61 indicated by arrow A is larger than the phase range in the circumferential direction of the bundled body occupied by contracted portion 62 indicated by arrow B in FIG. 4. Is preferred. Moreover, it is more preferable that the circumferential phase ratio of the binding body 60 occupied by the non-shrinking portion 61 is 60% or more, and the circumferential phase ratio of the binding body 60 occupied by the non-shrinking portion 61 is 70% or more. Particularly preferred.

  With reference to FIG. 1 again, the collective package 50 will be described. In the collective package 50, the package 10 is stacked in one direction so that the substantially central portions in the width direction of the body sheet 11, 12 are in contact with each other. In the example shown in FIG. 1, the back sheet 12 of the packaging body 10 located on the left side is in contact with the top sheet 11 of the packaging body 10 located on the right side. When viewed from one direction, the top sheet 11 of one package 10 substantially overlaps the back sheet 12 of the other package 10. As a result, in the collective package 50, the side seal portions 22 provided on both sides of one package 10 are spaced apart in the one direction from the side seal portions 22 provided on both sides of the other package 10. In the state, it is substantially opposed to the one direction.

  The lower end portion of the top sheet 11 of the one package 10 and the lower end portion of the top sheet 11 of the other package 10 are aligned in a direction perpendicular to the axial direction of the package 10. Moreover, the upper end part of the surface sheet 11 of one package 10 and the upper end part of the surface sheet 11 of the other package 10 are aligned in a direction orthogonal to the axial direction of the package 10. In the state where the packaging structure 80 is upright, the upper end in the height direction where the plug 30 is present in one package 10 is the upper end in the height direction where the plug 30 is present in the other package 10. The height direction position of the upper end part of one packaging body 10 substantially coincides with the height direction position of the upper end part of the other packaging body 10. In addition, with the packaging structure 80 upright, the lower end in the height direction of one package 10 substantially overlaps the lower end in the height direction of the other package 10 in the horizontal direction. The position in the height direction of the lower end portion of 10 substantially coincides with the position in the height direction of the lower end portion of the other package 10.

  According to this embodiment, since the height direction position of the lower end part of one package 10 is aligned with the height direction position of the lower end part of the other package 10, the upright posture of the collective package 50 is maintained. It can be stabilized. Further, as described above, since the bottom sheet 13 and the top sheet 14 have substantially the same size in a form in which the body portion is swollen, from this point of view, the united state can be well maintained and The posture can be maintained stably.

  It is assumed that the packaging structure 80 is arranged on a product shelf or the like in such a posture that one side end of the contact portion 43 in the two packaging bodies 10 is directed to the front and the purchaser can visually recognize the two packaging bodies 10. Has been. For example, the bundle 60 has a product name, a manufacturer name, a logo, a character, a background in the vicinity of an area 42 enclosed by a square in FIG. 1 in the front portion facing one side end of the contact portion 43. Etc., and a mechanical reading symbol such as a bar code is provided. In addition, as shown in FIG. 1, in that case, the side of the bundled body 60 that is directed to the front side may be configured by a non-shrinkable portion 61, and the area 42 may exist in the non-shrinkable portion 61.

  FIG. 5 is a schematic diagram illustrating an example of a laminated structure in the radial direction when the design layer 72 is provided in the non-shrinkable portion 61. As shown in FIG. 5, the portion 61 a provided with the design layer 72 in the non-shrinkable portion 61 is, for example, disposed inside the transparent heat-shrinkable film layer 71 and heat-shrinkable film layer 71 disposed on the outside. Design layer 72, dry laminate adhesive layer 73 provided inside design layer 72, transparent non-heat-shrinkable film layer 74 provided inside dry-laminate adhesive layer 73, and non-heat-shrinkable film layer The white layer 75 provided inside 74 can be configured.

  For example, the design layer 72 is formed by combining a plurality of print layers having different colors. However, the design layer 72 may be formed by using one print layer and a portion where the print layer is provided and a portion where the print layer is not provided. Although the thickness of the design layer 72 is not specifically limited, Preferably it is 0.1 micrometer-5 micrometers.

  The printing layer can be formed using a conventionally known oil-based ink (solvent ink) or water-based ink. These inks contain, for example, a binder resin, a color material, an optional additive, a solvent or a dispersion medium (hereinafter referred to as a solvent), and the binder resin or the color material is dissolved or dispersed in the solvent. is there. Although a solvent etc. will not be specifically limited if binder resin etc. can be melt | dissolved or disperse | distributed, In the case of water-based ink, it contains water. The printing layer can be formed by a conventionally known printing method such as a gravure printing method, a flexographic printing method, a letterpress rotary printing method, and an ink jet printing method. With these printing methods, ink is applied onto the film substrate, and then the solvent and the like are removed by volatilization to form a printing layer containing a color material, a binder resin, and an optional additive.

  The white layer 75 is provided, for example, to conceal the outer surface of the package disposed inside the white layer 75 so that it cannot be visually recognized. The white layer 75 is a layer containing at least one of a white color material and a void. The white layer 75 may contain a color material other than white, but is preferably composed of only a white color material as the color material. Examples of the white coloring material include white pigments such as titanium oxide, zinc white (zinc white), lead white, and ritbon (a mixture of barium sulfate and zinc sulfide), and titanium oxide is preferable. A slip layer may be disposed inside the white layer 75.

  In FIG. 5, the example which forms the design layer 72 inside the heat-shrinkable film layer 71 in the non-shrink part 61 was demonstrated. However, the design layer may be formed on the outer side of the heat-shrinkable film layer in the non-shrinkable part, or may be formed on both the outer side and the inner side of the heat-shrinkable film layer in the non-shrinkable part. It may be formed on the outer side, the inner side, or both of the film layer, or both the heat-shrinkable film and the non-heat-shrinkable film. In addition, the design layer may be provided on the inner side, the outer side, or both the inner side and the outer side of the heat-shrinkable film layer in the shrinkage portion.

  FIG. 6 is a perspective view of the packaging structure 80 when viewed from the side on which the packaging structure 80 is assumed to be directed to the back side when displayed on a product shelf or the like.

  As shown in FIGS. 1 and 6, the side seal portions 22 of the one and the other packaging bodies 10 are in contact with the binding body 60. The top sheet 11 of one package 10 and the back sheet 12 of the other package 10 define a recessed space 46 that is pointed at the side end side of the contact portion 43 between the top sheet 11 and the back sheet 12. ing. A circumferential portion located between the portion of the bundle 60 that contacts the side seal portion 22 of one package 10 and the portion of the other package 10 that contacts the side seal portion 22 faces the recess space 46. .

  Referring to FIGS. 3 and 6, the circumferential dimension of the contraction portion 62 of the bundle 60 before the heat shown in FIG. 3 is applied is shown in FIG. It is larger than the circumferential dimension of the contraction portion 62 of the bundled body 60 in the bound state. The packaging structure 80 shown in FIGS. 1 and 6 is configured to cover the periphery of the collective packaging body 50 with a sleeve-like bundle 60 before heat application so that the contraction portion 62 includes the entire region facing the recessed space 46. It is formed by applying heat to shrink the circumferential dimension of the contraction portion 62.

  As shown in FIG. 6, in a state after the heat is applied and the contraction part 62 contracts, the contraction part 62 is arranged to face the other side end of the contact part 43 of the two packaging bodies 10. The contraction part 62 is disposed so as to face the recess space 46. As shown in FIG. 6, when the circumferential length of the contraction portion 62 is longer than the circumferential length of the portion facing the recess space 46 in the bundle 60 after application of heat, the contraction portion 62 It is particularly preferable to include the entire circumferential region of the portion facing 46. Further, after the application of heat, when the circumferential length of the contraction body is shorter than the circumferential length of the portion facing the recess space in the bundle, the entire area of the contraction portion is included in the portion facing the recess space. Particularly preferred. In addition, as in these examples, the contraction part is preferably arranged so as to include at least a part of a circumferential region facing the recess space in the bundle in a state after application of heat. You may arrange | position in places other than the circumferential direction area | region which opposes a recessed part space in a binding body in the state after provision of heat.

  According to this embodiment, the contraction part 62 is on the other side end of the contact part 43 of the two packaging bodies 10 that are overlapped so that the substantially width direction center parts of the body sheet 11, 12 are in contact with each other. It arrange | positions so that it may oppose. On the other hand, the non-shrinking part 61 has a part arranged so as to face one side end of the contact part 43. In addition, the non-shrinkable portion 61 also has a portion disposed so as to face the back sheet 12 of one package 10 and the top sheet 11 of the other package 10 in close contact with each other. Therefore, the ring-shaped bundle 60 has a portion facing the recessed space 46 formed in the vicinity of the side end of the contact portion 43 of the two packaging bodies 10 that contact the body sheet 11, 12 when heat is applied. Shrink. As a result, since the annular bundle 60 is contracted at a location where the degree of freedom of contraction is larger than the concave space 46, the annular bundle 60 is less likely to be wrinkled, and the packaging structure 80 has an aesthetic appearance. It can suppress that it is damaged by the wrinkle of the binding body 60. Furthermore, since the non-shrinkable portion 61 is disposed so as to face the back sheet 12 of one package 10 and the top sheet 11 of the other package 10 in close contact with each other, the wrinkles are less likely to shift and the aesthetic appearance is excellent. .

  As shown in FIGS. 1 and 6, it is preferable to attach a tack label 19 constituting the tack sheet so as to straddle the trunk sheet 11 (or 12) and the outer surface of the bundle 60 so that the bundle 60 can be prevented from coming off. As shown in FIG. 6, it is preferable that the bundled body 60 has a perforation 67 extending in the height direction of the packaging structure 80 (the height direction of the collective package 50). The product purchaser can easily divide the collective package 50 and break out the package 10 by breaking the bundle 60 along the perforation line. As shown in FIG. 6, it is preferable that the perforation 67 is disposed in the packaging structure 80 so as to face the recessed space 46 because the perforation 67 is easily cut. In addition, in the example shown in FIG.1 and FIG.6, the tack label 19 has the front which a buyer can visually recognize when it sees from the front side in the center of the width direction of the back surface sheet 12 of one package 10, and the front side. It is pasted so as to straddle the back surface that the purchaser cannot see when viewed from above. Further, the tack label 19 is affixed to the surface of the region corresponding to the non-contracted portion 61 in the bundle 60. In the example shown in FIGS. 1 and 6, two perforations 67 are provided in a region corresponding to the contracted portion 62 of the bundle 60 so as to face the recessed space 46. However, the tack label 19 and the perforation 67 constituting the tack sheet may be provided as in the following preferred modification.

  Specifically, as in the modification shown in FIG. 14, the bundled body 60 is formed in a portion of the collective package 50 that faces the recessed space 46 around the side end of the contact portion 43 of the two packages 10. The tack sheet 67 has a perforation 67 extending in the height direction, and is pasted across the surface of the binding body 60 and the surface of the trunk sheet so that the distance from the perforation 67 is 30 mm or less. May be provided. At this time, the distance between the tack sheet and the perforation 67 is more preferably 20 mm or less, and most preferably 10 mm or less. According to this modification, since the peripheral portion of the perforation 67 is fixed by the tack sheet, when the purchaser tries to cut the perforation 67, the perforation 67 is easily cut.

  Specifically, the modified example will be described with reference to FIG. 14, and the description of the modified example will mainly describe a configuration different from the example shown in FIGS. 1 to 6, and is the same as the example. The description of the embodiment shown in FIGS. 1 to 6 can be referred to for the configuration of FIG.

  In the modification shown in FIG. 14, the binding body 60 has two perforations 67 extending in the height direction of the collective packaging body 50 at a portion facing the recessed space 46 around the other side end of the contact portion 43. The position at which the first tack label 19a constituting the tack sheet is 30 mm or less from the perforation 67 (specifically, the perforation on the side closer to the first tack label 19a of the two perforations 67). The distance between the second tack label 19b constituting the tack sheet and the perforation 67 (specifically, the perforation on the side closer to the second tack label 19b of the two perforations 67) is 30 mm or less. It is pasted at the position.

  The 1st tack label 19a is stuck so that the surface of the binding body 60 and the surface of the back surface sheet 12 of one packaging body 10 may be straddled, and perforation among the surfaces of the back surface sheet 12 of one packaging body 10 is carried out. It is affixed at a position that is biased toward the edge side close to the recessed space 46 facing the 67. That is, the first tack label 19a is the surface of the back sheet 12 of one package 10, and the distance from the edge close to the recessed space 46 facing the perforation 67 is the recessed space 46. It is pasted so as to be smaller than the distance from the far edge.

  The 2nd tack label 19b is stuck so that it may straddle the surface of the binding body 60, and the surface of the surface sheet 11 of the other package 10, The perforation among the surfaces of the surface sheet 11 of the other package 10 It is affixed at a position that is biased toward the edge side close to the recessed space 46 facing the 67. More specifically, the second tack label 19b is the surface of the back sheet 12 of the one package 10, and the distance from the edge near the recessed space 46 facing the perforation 67 is It sticks so that it may become smaller than the distance with the edge of the far side to the recessed part space 46. FIG.

  In particular, when the recessed space 46 facing the perforation 67 is on the back side, the tack labels 19a and 19b are attached to positions that are biased toward the edge side closer to the recessed space 46, so that they can be viewed from the front side. It is preferable because the tack labels 19a and 19b are less noticeable.

  As shown in FIGS. 1 and 6, the bundled body 60 is slightly more than the end 36 on the top sheet 14 side of the side seal portion 22 that forms a joint between both side edges of the body sheet 11, 12 in the package 10. It is preferable to cover the region from the position located on the bottom sheet 13 side to the lower end of the trunk sheet 11,12.

  If the central part in the height direction of the collective package is tightened with an annular bundle, a part of the contents move to the lower side of the pouch container, so that the bottom of the collective package is expanded in the packaging structure. There is a risk of an unstable shape. On the other hand, when the lower end part side of the collective package 50 is tightened with the annular bundle 60 as in the present embodiment, a part of the contents can be moved to the upper side where the pouch container 40 is not tightened. . Therefore, the bottom side structure of the collective package 50 is a structure in which a plurality of packages 10 are in close contact with each other, and the shape of the cut surface perpendicular to the height direction of the collective package 50 is not significantly changed in the height direction. It can be close to the size of the cylinder. Therefore, the adhesiveness of the lower side of the collective package 50 can be improved, a good restraint state can be established on the lower side of the packaging structure 80, and the package 10 constituting the collective package 50 as in this embodiment. When the lower end portion of the collective package 50 is placed on the horizontal plane, the lower end portion of the collective package 50 is tightened, so that the contents are lowered by its own weight. It is possible to suppress the content from being biased downward by moving, and it is relatively difficult for the content to move downward. Therefore, when the uprightness of the packaging structure 80 is required, a good restraint state can be established on the lower side of the packaging structure 80, and the packaging structure 80 can be stably erected.

  Further, since the binding body 60 covers the bottom sheet 13 side rather than the end on the top surface sheet 14 side of the side seal portion 22 at both side edges of the body part sheet 11, the binding body 60 covers the top surface sheet 14. There is nothing. Therefore, distortion of the top sheet 14 can be suppressed, and the binding body 60 can also be prevented from wrinkling by a local force from the top sheet 14, and the appearance of the packaging structure 80 can be prevented from being damaged.

  The bundle 60 may cover any position in the height direction of the collective package 50, but preferably covers at least the lower ends of the body sheets 11 and 12 in the collective package 50, and further the packaging. It is particularly preferable to cover the region from the height exceeding the midpoint of the body 10 in the height direction to the lower end of the body sheets 11 and 12 of the package 10. When the trunk portion of the collective package is defined as an area where the trunk sheet is present, it is preferable that the annular bundle covers 50% or more or 60% or more in the height direction of the trunk portion in the collective package. . Further, it is particularly preferable that the annular bundle includes the lower end portion of the body portion and covers 50% or more or 60% or more of the body portion in the height direction. Further, the annular bundle may cover the entire body part, but preferably has an uncovered region. The uncovered region is preferably 5% to 50%, 10% to 40%, or 15% to 30% in the height direction of the body portion. Moreover, it is preferable that the upper side of the collective package is not covered.

  According to the above-described embodiment, the pouch container 40 has the top sheet 14 and the bottom sheet 13 on both the upper and lower end sides of the pair of body sheet sheets 11 and 12 joined at both edges in the width direction. Therefore, the package 10 filled with the contents in the pouch container 40 is close to the size of the cylinder, and the shape of the cut surface perpendicular to the height direction is higher than that of the package without the top sheet or the bottom sheet. Does not change much in the direction. Therefore, the packaging structure 80 in which a plurality of packaging bodies 10 having such a shape are bound so as to overlap the trunk portion sheets 11 and 12 can increase the adhesion of the trunk portion sheets 11 and 12, and thus the binding state is good. The stability of the bound state is improved. In addition, since a good binding state can be maintained, even when the packaging structure 80 is required to be upright, the binding can be performed only by aligning the height direction positions at the lower ends of the plurality of packaging bodies 10 as in the present embodiment. The upright posture in the state can be stabilized.

  Moreover, since the adjacent package 10 is piled up so that the substantially width direction center part of mutual trunk | drum sheet | seats 11 and 12 may contact, the two packages 10 and 10 can be contact | adhered and collective packaging is possible. The body 50 can be configured compactly and stably. Therefore, the stability of the bundled state of the packaging structure 80 can be further improved.

  Further, since the bundled body 60 is formed of an annular band-shaped member surrounding the collective package 50, the collective package 50 can be tightened over the entire circumference by the bundle 60, and the integrated state of the collective package 50 is more stable. Can be maintained.

  Moreover, since the binding body 60 has the contraction portion 62 that contracts by heat in the second portion in the circumferential direction, the binding body 60 having a large diameter before applying heat is disposed around the assembly package 50, and then the heat By narrowing the diameter of the bundled body 60 simply by providing the above, the assembled package 50 can be easily and appropriately fastened by the bundled body 60.

  Moreover, since the binding body 60 has the contraction part 62 and the non-contraction part 61, the collective package 50 can be fastened with an appropriate fastening force. Therefore, the package 10 can be reliably bound, and the aesthetic appearance of the bound state can be made relatively excellent.

  In this embodiment, the case where the sleeve-like binding body 60 has the non-shrinking portion 61 and the shrinking portion 62 has been described. However, the sleeve-like binding body may consist of only the shrinking portion, and the non-shrinking portion. It may consist of only parts.

  Moreover, in the said embodiment, the front part of the binding body turned to the front side with a goods shelf etc. was comprised by the non-shrink part 61, and the example which provides the design layer in the area 42 vicinity of the non-shrink part 61 was demonstrated. However, the front part of the binding body that is directed to the front side of the product shelf or the like may be configured by a contraction part, and a design layer may be provided on the contraction part that constitutes the front part.
