Description

  The present invention relates to a packaging container and a method for disassembling the same.

  As described in Patent Document 1, a layer having a barrier property such as an aluminum foil, an aluminum vapor-deposited film, or an inorganic oxide vapor-deposited film is laminated between a paper base material layer and a thermoplastic resin sealant layer. 2. Description of the Related Art A packaging container is known that is formed by folding a sheet material into a box shape and overlapping and sealing the end portions.

  There are various forms of such packaging containers. As one of them, a spout made of polyethylene or the like is provided on the roof plate of the gable top type (gable roof type) to pour out the content liquid. Possible packaging containers are known. In the case of such a packaging container, at the time of disposal, in order to separate and collect, in order to separate the container main body made of paper sheet material and the spout stopper, the top seal portion is opened and scissors are used. It was difficult to cut the periphery of the spout stopper and separate the spout stopper from the packaging container. However, since such a packaging container has a strong sealing by heat sealing of the top seal part, when disassembling the empty container after use, it is necessary to open the top seal part by hand and disassemble the container. There was something difficult. This is because the top seal part seals in a state where the folded laminate hits, so that a gap is likely to occur. Therefore, the sealant layer on the back surface of the liquid paper container is made of polyethylene resin having good fluidity at the time of melting. This is because the sealing strength is increased because the sealing is performed at a high temperature and a strong pressure, and the gap is filled and completely sealed. If the sealing temperature is lowered or the pressure is weakened in order to weaken the sealing strength, there is a risk that sealing will be incomplete and liquid leakage will occur. Therefore, it is recommended not to open the top seal part, but to cut the empty container by cutting with a scissor from the opening part of the plug, but it is extremely difficult to cut a hard plug with scissors. It is not generally done.

  Therefore, in Patent Document 2, a peelable pull tab is provided on the side seal of the container body that is sealed with the both ends of the paper base material sheet being overlapped with each other, and the pull tab is a release layer made of an easily peelable tape-like film. There is disclosed a liquid packaging paper container that is detachably provided via the. In this liquid packaging paper container, the side seal part is peeled off by pulling the pull tab, or the side plate is cut by pulling the pull tab provided on the side plate, and the liquid packaging paper container body is disassembled as a trigger. can do.

  Patent Document 3 discloses a paper package in which a spout having a weakened portion is attached to a paper container having a bending guide line. According to this paper package, the weakened portion of the spout is broken by folding along the folding guide line, and the spout can be separated from the paper container.

A part of the fragile portion 105 is divided by the extraction hole 112. That is, a broken line formed by bending the container body 100 along the fragile portion 105 passes through the extraction hole 112.

  FIG. 3A is a plan view of the vicinity of the top portion 101 of the blank 20 which is a modification of the blank 10. The difference between the blank 10 and the blank 20 is a place where the weakened portion is formed. As shown in FIG. 3 (a), the fragile portion 105 ′ of the blank 20 has fragile portions 105′a and 105′b formed in a predetermined range across the boundary between the roof plates 106a and 106b and the folding plate 107. Including. In either case, the container body 100 is formed in a linear shape over the width direction, which is the left-right direction when the container body 100 is erected. A broken line formed by bending the container body 100 along the fragile portion 105 ′ passes through the extraction hole 112.

  FIG. 3B is a plan view of the vicinity of the top 101 of the blank 30 which is a modification of the blank 10. The difference between the blank 10 and the blank 30 is a place where the weakened portion is formed. As shown in FIG. 3 (b), the fragile portion 105 ″ is fragile so as to surround the outlet hole 112 in addition to the fragile portion 105 a ″ formed at the same location as the fragile portion 105 of the blank 10. Part 105b ″. A broken line formed by bending the container main body 100 along the fragile portion 105 a ″ passes through the extraction hole 112. Note that the fragile portion 105a '' only needs to be able to pass through the extraction hole 112, and the fragile portion 105a '' may be in contact with the fragile portion 105b '' or the extraction hole 112, It is not necessary to touch. In the following description, unless otherwise specified, the fragile portion 105 includes the fragile portion 105 ′ and the fragile portion 105 ″.

  4A and 4B are cross-sectional views schematically showing examples of the laminated structure of the sheet material 200 used for the blank. The sheet material 200 includes a printing layer 208 / thermoplastic resin layer 201 / paper base material layer 202 / adhesive resin layer 203 / barrier layer 204 / adhesive layer 205 / sealant layer in order from the outside to the inside of the packaging container 1. 206. The difference between the example shown in FIG. 4A and the example shown in FIG. 4B will be described later.

  As shown in FIGS. 4A and 4B, the weakened portion 105 of the sheet material 200 is configured by groove-shaped scratched portions 207a and 207b formed at a predetermined depth in at least the paper base material layer 202 and the barrier layer 204. . At this time, the scratched portion 207 b of the barrier layer 204 is formed at a position overlapping the scratched portion 207 a of the paper base material layer 202. The overlapping position refers to a range where the displacement between the scratched portions 207a and 207b is within ± 3 mm. The scratched portion 207b is desirably formed at a depth that does not penetrate the barrier layer 204, but even if it penetrates in a narrow range, the barrier property is less affected, and may partially penetrate the barrier layer 204. . The scratch processing portion 207a only needs to be formed on at least the paper base material layer 202, and is laminated on the outside of the paper base material layer 202 together with the paper base material layer 202 as shown in FIGS. 4A and 4B. Further, it may be formed on the thermoplastic resin layer 201 and the print layer 208.

  The flaw processing portion 207a can be formed with a depth that allows the paper base material layer 202 to ensure the strength of the packaging container 1. As a method for forming the scratched portion 207a, there are a half punching process and a full punching process using a blade die. In order to ensure the strength of the packaging container 1, these flaws can be formed in a perforated shape. The scratched portion 207b can be formed by laser beam processing after bonding the barrier layer, but when formed before bonding the barrier layer, half-cutting processing or full-cutting processing using a blade die is performed. Can be used. Even when the scratched portion 207b is provided before the barrier layer is bonded, it may be formed by laser processing. The scratched portion 207b may also be formed in a perforated shape to ensure strength.

  The thermoplastic resin layer 201 can be formed on the paper base layer 202 by extrusion lamination or the like using a low density polyethylene resin (LDPE), a linear low density polyethylene resin (LLDPE), or the like.

  A print layer 208 may be provided outside the thermoplastic resin layer 201 to display a pattern or product information. The printing layer 208 can be formed by a method such as gravure printing or offset printing using a known ink. Adhesiveness such as corona treatment can be applied to the thermoplastic resin layer 201 to enhance the adhesion with the printing layer 208. An overcoat layer may be provided outside the printed layer in order to improve wear resistance or surface decoration.

  For the paper base layer 202, paperboard such as milk carton base paper can be used. The basis weight and density can be appropriately selected depending on the capacity and design of the container.

  The adhesive resin layer 203 is a layer made of a polyolefin resin having a function of adhering the paper base material layer 202 and the barrier layer 204. Specifically, high density polyethylene resin (HDPE), medium density polyethylene resin (MDPE), LDPE, LLDPE, ethylene / methacrylic acid copolymer (EMAA), ethylene / acrylic acid copolymer (EAA), ionomer, polypropylene (PP) or the like can be used. In order to increase the adhesive strength, the surface of the paper base material layer 202 or the barrier layer 204 may be subjected to corona treatment, ozone treatment, anchor coating, or the like. Alternatively, an adhesive layer using a dry laminate adhesive or the like may be used instead of the adhesive resin layer.

  The barrier layer 204 is a vapor-deposited film including a vapor-deposited layer 204b obtained by vapor-depositing a metal such as aluminum, silica, or alumina, and a base film 204a, or a laminated film obtained by dry-laminating a metal foil 204c such as aluminum on the base film 204a Can be used. In the example illustrated in FIG. 4A, the barrier layer 204 is a vapor deposition film, and includes a base film 24 a and a vapor deposition layer 204 b provided on the inner side surface of the packaging container 1. In the example shown in FIG. 4B, the barrier layer 204 is a laminated film, and includes a base film 204 a and a metal foil 204 c provided on the outer side of the packaging container 1. Further, in the case of using a laminated film and forming the scratched portion 207b by laser light irradiation, as shown in FIG. 4B, a barrier is provided so that the metal foil 204c does not block the laser light irradiation to the base film 204a. The layer 204 is laminated so that the vapor deposition layer 204 b or the metal foil 204 c faces the adhesive resin layer 203. As the barrier layer 204, a barrier-coated polyethylene terephthalate film obtained by applying a barrier coating to a polyethylene terephthalate film or a barrier film made of a barrier material such as EVOH can be used.

  As the base film 204a, a resin film such as polyethylene terephthalate (PET), nylon, or polypropylene (PP) can be used. In particular, a biaxially stretched film of PET is suitable because it has little expansion and contraction during vapor deposition and bonding.

  For the adhesive layer 205, a dry laminating adhesive or a non-solvent laminating adhesive may be used, or an extruding process may be used to adhere with a polyolefin resin.

  HDPE, MDPE, LDPE, LLDPE, etc. can be used for the sealant layer 206. There may also be a layer partially containing polybutene. Among the above materials, LLDPE is particularly preferable. The sealant layer 26 is preferably an unstretched film formed by a T-die method or an inflation method.

  FIG. 5A shows a cross-sectional view of the spout 104a. The spout 104a is formed on a cylindrical side wall 301, a disk-shaped flange portion 302 extending outward from the lower end of the side wall 301, and an inner periphery of the lower end of the side wall 301 to block the inside and the outside of the packaging container. It includes a disk-shaped partition wall 303 and a pull ring 304 that extends upward from the partition wall 303 and is used when a user removes the partition wall 303. On the outer periphery of the side wall 301, a male screw 305 that is screwed with a female screw formed on the inner periphery of the cap 104b is formed. The spout 104a is fixed by joining the flange portion 302 and the roof plate 106a around the pouring hole 110 by, for example, ultrasonic welding after passing the side wall 301 through the pouring hole 110. A thin-walled portion 306 is formed below the side wall 301 and in the vicinity of the joint with the flange 302 so as to reduce the plate thickness continuously or intermittently on the outer periphery of the side wall 301.

  FIG. 5B shows a spout 104a 'according to a modification of the spout 104a. The difference between the spout 104a and the spout 104a 'is a place where the thin portion 306' is formed. As shown in FIG. 5B, the thin portion 306 ′ is formed on the lower surface of the flange portion 302 in a continuous or intermittent ring shape with a reduced thickness of the flange portion 302. The formation surface of the thin portion is not limited to the lower surface, and may be provided only on the upper surface or on both surfaces.

  FIG. 5C shows a spout 104a ″ according to a modification of the spout 104a. The difference between the spout 104a and the spout 104a 'is the presence or absence of the thin portion 306. As shown in FIG. 5C, the thin portion 306 is not formed in the spout 104a ''.

  As for spout 104a and 104a ', the thin part is provided in the spout, and the thin part breaks at least partially by bending the container body along the weak part, as will be described later.

  FIG. 6 shows a disassembly method according to the embodiment of the present invention. Below, based on FIG. 6, each process of this embodiment is demonstrated. Below, the container main body 100 and the spout 104a disassembly method using the blank 10 are demonstrated.

<Crushing process>
FIG. 6A shows a step of crushing the packaging container 1. In this step, the user of the packaging container 1 crushes the trunk portion 102 by pushing the two opposing side plates 107 extending below the roof plate 106 in a direction in contact with each other. The two side plates 107 in contact with the side plates 107 to be crushed are folded in the inner direction of the packaging container 1.

<First bending process>
FIG. 6B shows a process of bending the packaging container 1 along the fragile portion 105. In this step, the user bends the roof portion 106 along the fragile portion 105 as shown in FIG. At this time, the broken line formed on the roof plate 106 passes through the pouring hole 112.

  Since the broken line formed on the roof plate 106 passes through the pouring hole 112, a load is applied so that a part of the flange portion 302 of the spout 104a attached to the pouring hole 112 is also bent in the same direction as the roof plate 106a. Will be added. Here, when the thin portion 306 is formed in the spout 104a, the spout 104a is broken at least partially from the thin portion 306 as shown in the cross-sectional view on the right side of FIG. Arise.

<Outlet plug separation process>
FIG. 7A shows a process of separating at least a part of the spout stopper 104 from the packaging container 1. Since the thin portion 306 of the spout 104a is broken in the previous step, the user can separate the spout stopper 104 from the packaging container 1 with a slight force starting from this.

<Second folding process>
FIG. 7B shows a process of breaking the packaging container 1 along the fragile portion 105. In this step, as shown in FIG. 7B, the user bends the roof plate 106 along the fragile portion 105. Bending may be performed multiple times in each direction.

  By this process, the fracture of the fragile portion 105 proceeds. In addition, when the weak part 105 fractures | ruptures over sufficient range by the 1st bending process, you may abbreviate | omit this process.

<Roofing plate separation process>
FIG. 7C shows a process of separating a part of the roof plate 106 from the packaging container 1 along the fragile portion 105. In this step, the user tears and separates a part of the roof plate 106 from the packaging container 1 along the fragile portion 105 and the bent portion. In the previous step, since the fragile portion 105 is at least partially broken, the user can separate the upper portion of the roof plate 106 with a slight force starting from the fragile portion 105. As shown in FIG. 6D, the separated packaging container 1 is disassembled with the upper portion of the roof plate 106, the trunk portion 102, and the spout tap 104 being in separate states.

  As described above, according to the disassembling method, the spout stopper can be easily separated with a slight force. Further, when the fragile portion is provided in the width direction, it is possible to obtain an advantage that the upper side and the lower side of the fragile portion can be easily grasped by hand, and the packaging container 1 can be easily bent. Since it can be easily separated from the packaging container 1, it is easy to disassemble the body part thereafter, so the plug can be removed and the body part can be disassembled in a series of flows, so there is no trouble for consumers to disassemble. . Moreover, since the top part including the top seal part that is firmly sealed and difficult to recycle can be separated from other parts, disassembly suitable for recycling can be performed. On the other hand, when the fragile portion is provided along the height direction orthogonal to the width direction of the packaging container 1, the left and right sides of the fragile portion are respectively grasped by hand and firmly sealed to provide a highly rigid top seal. It is necessary to bend including the part. Therefore, compared with the case where a weak part is provided along the width direction, it will be hard to grasp the packaging container 1 and will require big force. Further, in order to separate the top seal portion from other portions, it is necessary to separate the top seal portion with scissors or the like, and it is troublesome to perform disassembly suitable for recycling. Therefore, the direction in which the fragile portion is formed is preferably in the width direction rather than the height direction of the packaging container 1.

  The above-described disassembling method can be applied to any combination of a container body manufactured from the blank 10 or the blank 20 and the spout 104a, the spout 104a ', or the spout 104' '.

  Even in the case of a container body using the blank 30, the packaging container can be disassembled in substantially the same manner as the disassembly method described above. In the first folding step, the fragile portion 105b '' is also at least partially broken. As a result, in the spout plug separation step, the entire spout can be easily separated along the weakened portion 105 b ″ along with the region of the container body surrounded by the weakened portion 105 b ″. Therefore, in the case of the container main body using the blank 30, a spout 104 a ″ in which a thin portion is not formed may be used in addition to the spouts 104 a and 104 a ′.

  The packaging container which concerns on Examples 1-3 was created, and it evaluated about the dismantling method of the packaging container which concerns on this invention.
