JP 2003-155042 A

  When the contents are coins or banknotes, in order to prevent the contents from being stolen during transportation and to be able to confirm whether or not the contents have been opened, no trace is left on the pouch. Therefore, it is required to be difficult to open.

  Therefore, it is conceivable that the pouch is sealed with a tamper-proof tape so that a trace appears on the tamper-proof tape when opening is attempted.

  As an anti-falsification tape, a tape having a structure that allows a visible trace to be generated by bending generated at the time of peeling has been proposed (Japanese Patent Laid-Open No. 2005-227445). However, there has been no anti-falsification tape that can adhere to both the front and back films of the pouch with an appropriate peel strength and seal the pouch appropriately.

  Moreover, it is preferable that the pouch can automate the sealing operation by a machine.

  Therefore, an object of the present invention is to provide a pouch excellent in security capable of preventing the theft of contents due to the appearance of an opening trace.

  The present invention relates to a pouch body formed by sealing peripheral edges of a first side film, a second side film, and a bottom film made of a resin film, excluding an opening, and a pouch body of the first side film. One side is affixed to the inner side of the opening over the entire width of the opening, the double-sided adhesive tape that seals the opening, and the other side of the double-sided adhesive tape that can be peeled off to protect the other side before sealing A mold label, and a first hook sheet and a second hook sheet, which are respectively bonded to the outer side of the pouch body of the first side film and the second side film over the entire width of the opening, The double-sided pressure-sensitive adhesive tape includes a print layer in which a release layer is partially laminated in a predetermined pattern, and the peel strength in the print layer is the peel strength between the double-sided pressure-sensitive adhesive tape and the first side film and Face adhesive tape and peeling strength is smaller than between the second side film, a pouch.

(First embodiment)
FIG. 1 is a plan view of the pouch 100 according to the present embodiment, and FIG. 2 is a schematic cross-sectional view of the pouch 100 along the line AA ′ shown in FIG.

  The pouch 100 includes a pouch body 105 formed by sealing the peripheral portions of the first side film 101, the second side film 102, and the bottom film 103 made of a resin film except for the opening 104, Tape material 150 affixed to the inside of the pouch of the opening 104 of the side film 101, and affixed to the outside of the pouch of the opening 104 of the first side film 101 and the second side film 102, respectively. It consists of a first hook sheet 121 and a second hook sheet 122. The tape material 150 includes a strip-shaped double-sided adhesive tape 108 and a release label 151. The contents stored in the pouch 100 are not shown. Note that the pouch body 105 may be formed by using only the first side film 101 and the second side film 102 without using the bottom film 103 and sealing the periphery.

  The first hook sheet 121 and the second hook sheet 122 are attached to the first side film 101 and the second side film 102 over the entire width of the opening 104, respectively. The first hook sheet 121 and the second hook sheet 122 may be made of, for example, PET (polyethylene terephthalate) and have a thickness of 250 μm. Alternatively, paper may be used.

  One side of the double-sided adhesive tape 108 is affixed to the first side film 101, and the release label 151 is detachably affixed to the other side. The release label 151 protects the other surface of the double-sided pressure-sensitive adhesive tape 108 until the pouch 100 is sealed, and prevents it from being attached to the second side film 102. The release label 151 is made of, for example, a resin film coated with a release agent to facilitate peeling, or a paper on which the resin film is laminated.

  A plan view of the tape material 150 is shown in FIG. The release label 151 includes a protection part 152 that covers the double-sided adhesive tape 108, and a pulling margin part 153 that is connected to the center of the periphery of the protection part 152. The connecting portion between the protection portion 152 and the pulling allowance portion 153 is formed with a crease line 161, and the pulling allowance portion 153 is formed on the outside of the pouch body 105 along the crease line 161 when attached to the pouch body 105. Wrapped

  In addition, the hooking portion 153 is formed with four hook holes 154 for applying a tensile force at the time of peeling. A cut may be provided instead of the hooking hole 154.

  A cut line 155 is formed in a linear shape extending from the end edge of the protection portion 152 to the two hooking holes 154 inside the pulling allowance portion 153. The cut 155 reduces the rigidity of the pulling allowance 153. Further, a stopper notch 158 that surrounds the end and is not connected to the notch 155 is formed near the end of the notch 155.

  As shown in FIG. 3B, the double-sided pressure-sensitive adhesive tape 108 is notched at the center portion including the peeling start position of one end edge, provided with a recess 159, and has a protrusion 162 at both ends of the recess 159. May be provided. Thereby, at the start of peeling, the total length of the peeling progress line 160 can be shortened, the peeling progress line can be shortened, the force required for peeling can be further reduced, and peeling can be facilitated.

  FIG. 4 shows a plan view of the first hook sheet 121. The first hook sheet 121 has a belt-like shape, and two pulling allowances 123 protrude from one side along the opening side of the pouch body 105. A hooking hole 124 is formed in the pulling margin 123. A notch 125 is provided in the corner on the front end side of one pulling allowance portion 123. The second hook sheet 122 has the same shape as the first hook sheet 121.

  Before being attached to the opening 104 of the pouch body 105, the tape material 150 is protected by being peelably bonded to the double-sided pressure-sensitive adhesive tape 108 in addition to the release label 151. The separator 170 has substantially the same shape as the double-sided pressure-sensitive adhesive tape 108, for example, and is made of a resin film coated with a release agent or a paper laminated with the resin film to facilitate peeling. In FIG. 5, the cross section of the tape material 150 and the separator 170 is shown typically. The double-sided pressure-sensitive adhesive tape 108 has a layer structure of a first pressure-sensitive adhesive layer / printing layer / peeling layer / base material / second pressure-sensitive adhesive layer from the side close to the separator 170. The release layer is partially provided in a predetermined pattern such as letters. For example, a 16 μm polyethylene terephthalate layer can be used as the substrate.

  The tape material 150 is attached to the pouch main body 105 by peeling the separator 170 from the double-sided pressure-sensitive adhesive tape 108 and attaching the exposed first adhesive layer to the opening 104 of the first side film 101 of the pouch main body 105. Do. The mounting operation is preferably performed by a machine.

  Hereinafter, the sealing operation of the pouch 100 will be described. First, the opening 104 side of the pouch 100 is inserted into a predetermined part of the machine. If the positioning is performed properly, the claw of the machine is hooked and attached to the hook holes 124 of the pulling portions 123 of the first hook sheet 121 and the second hook sheet 122. Further, another claw of the machine is hooked and attached to the hooking hole 154 of the pulling allowance portion 153 of the release label 151 of the tape material 150. Next, the machine pulls away the first hook sheet 121 and the second hook sheet 122 by a predetermined distance, and pulls the pulling allowance section 153 with the opening 104 of the pouch 100 opened, so that the protection section 152 is placed on both sides. Peel from the second adhesive layer of the adhesive tape 108. Thereafter, the second side film 102 is pressure-bonded to the second adhesive layer of the double-sided adhesive tape 108 to seal the opening 104.

  The first hook sheet 121 and the second hook sheet 122 give the opening 104 a certain rigidity. Thereby, during the above-described sealing operation, the first side film 101 and the second side film 102 are not wrinkled or warped, and the smoothness is maintained. Therefore, over the entire width of the opening 104, Secure sealing can be performed. In addition, since the pulling margin 123 of the first hook sheet 121 and the second hook sheet 122 has a certain rigidity, the notch 125 formed in the pulling margin 123 gradually approaches the sensor included in the machine. Can be detected by the sensor when it comes into contact with each other, so that the positioning accuracy can be improved. Furthermore, when the claw of the machine is caught in the hook hole 124 of each pulling allowance portion 123 of the first hook sheet 121 and the second hook sheet 122, a mounting sound is generated. It is possible to check the installation.

  FIG. 6A shows how the release label 151 is peeled off. The pulling force applied to the hooking hole 154 is transmitted to the connecting portion between the protection portion 152 and the pulling allowance portion 153. By the cuts 155 extending between the catching holes 154, the rigidity of the vicinity of the cuts 155 of the release label 151 is reduced, the displacement due to the pulling force is facilitated, the pulling force is concentrated, and the peeling start position is obtained. Further, since the peeling progress line 160 is easily bent at the cut line 155, the entire length of the peeling progress line 160 is shortened. As a result, the force required for peeling can be reduced, and the start of peeling from the double-sided pressure-sensitive adhesive tape 108 and the peeling progress can be facilitated. Further, the stopper cut 158 does not concentrate the pulling force on the end of the cut 155 on the pulling margin 153 side, and the end of the cut 155 is not torn. Thereby, it becomes easy to peel the release label 151 automatically using a machine. The above sealing work may be performed manually without using a machine.

  When the concave portion 159 and the convex portion 162 are provided on the double-sided pressure-sensitive adhesive tape 108, as shown in FIG. 6B, the total length of the peeling progress line 160 is shortened at the start of peeling, and the force required for peeling is further reduced. , Peeling can be made easier.

  Next, a case where an attempt is made to open the pouch 100 will be described. When the first side film 101 and the second side film 102 are pulled in the direction of separating to open the opening 104 of the pouch 100, the printed layer and the release layer of the double-sided pressure-sensitive adhesive tape 108 are separated. Moreover, in the area | region which has not provided the peeling layer, a part of printing layer is torn off and it remains in a base material layer. As a result, the pouch 100 is opened, but a pattern is developed by the printed layer remaining on the base material layer, and an opening trace remains. Thereby, an unauthorized opening act can be suppressed and the contents can be prevented from being stolen or falsified.

  The peel strength of the double-sided pressure-sensitive adhesive tape 108 is, in order from the strongest, the peel strength A of the print layer (peel strength between the print layer and the peel layer or the substrate layer), and between the second sticky layer and the release label 151 The peel strength B is preferably the peel strength C between the separator 170 and the first adhesive layer. First, in order to attach the tape material 150 to the pouch main body 105, the separator 170 is peeled off from the first adhesive layer, so that even if the peeling strength C is the smallest, peeling is performed with a machine that cannot perform delicate force adjustment. The separator 170 can be peeled from the first adhesive layer while preventing other portions from peeling. In addition, since the release label 151 is peeled from the second adhesive layer next, even if the peel strength B is smaller than the peel strength A, the printed layer and the peelable layer or the base material layer are peeled off by a machine. The release label 151 can be peeled from the second adhesive layer while preventing the peeling. As a result, the tape material 150 can be more stably attached and sealed.

  The peel strength A is preferably smaller than the peel strength between the first adhesive layer and the first side film 101 and the peel strength between the second adhesive layer and the second side film 102. As a result, when the first side film 101 and the second side film 102 are pulled away in order to open, the printed layer of the double-sided pressure-sensitive adhesive tape 108 and the release layer or the base material layer are reliably peeled off. Since the pattern is developed, the effect of preventing the contents from being stolen and falsified can be enhanced.

  A crease line may be formed on the release label 151 instead of the cut line 155. Further, the shape and number of cut lines and crease lines can be variously configured. The material, shape, and the like of the release label 151, the double-sided adhesive tape 108, the first hook sheet 121, and the second hook sheet 122 can be variously modified.
