Definitions

  • the present invention relates to a packaging bag with a zipper.
  • a conventional packaging bag with zipper of this kind is known from Utility Model Registration No. 2557256, for example.
  • a packaging bag is conventionally known wherein an openable and closable zipper which performs a male and female coupling action is provided at opposing positions of a bag in the vicinity of the opening end thereof, and in an integral fashion with the bag.
  • a packaging bag of the kind disclosed in Utility Model Registration No. 2557256 described above which comprises an integrally provided openable and closable zipper performing a male and female coupling action
  • the perimeter of the bag including the edge adjacent to the opening end of the bag close to a location of the zipper, is closed by heat sealing.
  • the bag cannot be opened by opening the zipper unless the heat seal section along the edge adjacent to the opening end of the bag is cut.
  • bags that are not heat sealed along the edge adjacent to the opening end of the bag close to the location of the zipper.
  • Such bags can simply be opened by opening the zipper at a shop display cabinet, for instance. If the bag is then closed again after opening, it cannot be identified whether or not it has been opened, posing management problems.
  • the present invention was devised to resolve the problems, an object thereof being to make it possible readily to identify whether or not a packaging bag with zipper has been opened.
  • a packaging bag with zipper in which the lower end portion of a male zipper tape and the lower end portion of a female zipper tape are bonded to the inner faces of respective front side and rear side sheet sections, or rear side and front side sheet sections, along the opening end of the bag.
  • the upper end of the bag comes at the top when the bag is in an upright state, and the respective zipper tapes are bonded together at a position below the engaging section thereof, with heat sealing strength of a degree that allows the zipper tapes to be manually peeled apart, by means of an interface peeling action, an interlayer peeling action, or a cohesive peeling action.
  • either one of the zipper tapes is made from a hot melt type adhesive resin, and the other zipper tape is made from a polyethylene type resin or a polypropylene type resin of the same kind as a material forming the inner layers of the bag.
  • either one of the zipper tapes is made from a hot melt type adhesive resin, and both the outer face and the inner face of the other zipper tape are made from a polyethylene type resin or a polypropylene type resin of the same kind as a material forming the inner layer of the bag.
  • one of the zipper tapes is made from a hot melt type adhesive resin
  • the outer face of the other zipper tape is made from a polyethylene type resin or polypropylene type resin of the same type as the material forming the inner layers of the bag
  • the inner face of the other zipper tape is made from a polyethylene type resin or polypropylene type resin of a different type from the material forming the inner layers of the bag.
  • the inner faces of both zipper tapes are made from a polyethylene type resin or polypropylene type resin, and a hot melt type adhesive resin section is provided on the inner face of one of the zipper tapes, at least in a bonding section formed by heat sealing in a position below the engaging section of the zipper tapes.
  • a hot melt type adhesive resin section that is to be bonded to the inner layer of the bag, is provided in at least the lower end portion of the outer face of the zipper tape made from a polyethylene type resin or a polypropylene type resin.
  • both zipper tapes are made from a resin containing a material comprising a random mixture of a straight-chain low-density polyethylene type resin and a polybutene-1 resin.
  • a resin section containing a material comprising a random mixture of a straight-chain low-density polyethylene type resin and a polybutene-1 resin is provided on the inner faces of both zipper tapes, at least in the bonding section formed by heat sealing below the engaging section of the zipper tapes.
  • the male zipper tape and the female zipper tape are respectively coloured with mutually different colours.
  • zipper tapes are bonded together at a position below the engaging section of the zipper tapes, with heat sealing strength that allows the bonding section of the zipper tapes to be peeled apart by hand.
  • the bonding section of the zipper tapes can be changed to a separate colour, by means of colour mixing, and if a user has mistakenly opened the zipper and peeled apart the bonding section of the zipper tapes, for example, the colour of the section will revert to the original colours of the respective zipper tapes. Thus, it is easy to identify whether or not the packaging bag has been opened.
  • numeral 1 denotes a packaging bag, and this packaging bag 1 is closed by heat sealing at three edges, namely, the lower end when the bag is in an upright state, and the two respective side edges.
  • Numeral 2 denotes the heat seal section of the bag.
  • Zipper tapes 5, 6 are provided in an integral fashion at the opening end of the bag which comes at the top when the packaging bag 1 is in an upright state, by heat sealing and bonding the lower end portion of a male zipper tape 5 and a female zipper tape 6 to the inner faces of respective sheet sections 3, 4 on the front side and rear side (or rear side and front side) of the bag 1.
  • the zipper tapes 5 and 6 are provided in such a manner that they project from the upper end of the packaging bag 1.
  • the sheet sections 3, 4 forming the packaging bag 1 have a two-layer structure in which the outer layers 3a, 4a thereof are made from nylon film and the inner layers 3b, 4b are made from polyethylene film, and the male zipper tape 5 and female zipper tape 6 which are bonded to the inner faces of these respective sheet sections 3, 4 along the opening end of the packaging bag 1 are made from materials described below.
  • A is a hot melt type adhesive resin
  • B is a polypropylene type resin
  • a polyethylene type resin layer 7 and a hot melt type adhesive resin layer 8 are formed respectively by combined extrusion on the material A forming the male zipper tape 5 and material B forming the female zipper tape 6, on the faces thereof which oppose the inner faces 3b, 4b of the respective sheet sections 3, 4.
  • the male zipper tape 5 and the female zipper tape 6 are heat sealed, respectively, onto the inner face of the sheet section 3 and the inner face of the sheet section, at a temperature of 180oC, for example, a sealing time of one second, and a sealing pressure of 20 N/cm 2 , then the polyethylene type resin layer 7 of the zipper tape 5 and the inner layer 3b of the polyethylene film of the sheet section 3 fuse together, and the hot melt type adhesive resin layer 8 of the zipper tape 6 fuses with the inner layer 4b of the polyethylene film of the sheet section 4.
  • the polyethylene type resin layer 7 of the zipper tape 5 and the polyethylene film of the inner layer 3b of the sheet section 3 are of the same type and become completely fused together, and the hot melt type adhesive resin layer 8 of the zipper tape 6 and the polyethylene film of the inner layer 4b of the sheet section 4 are bonded together by a heat sealing strength of approximately 5 N/15 mm.
  • the hot melt type adhesive resin has characteristics whereby, when heated, it bonds with polyolefin type resins, such as polyethylene, and has a heat sealing strength with polyolefin type resins of 5 N/15 mm or above.
  • the respective zipper tapes 5, 6 are bonded together by heat sealing along a lower end in the width direction of the zipper portion when the packaging bag 1 is in an upright state, in such a manner that the zipper tapes can be peeled apart by an interface peeling action.
  • Numeral 9 denotes a bonding section between the zipper tapes 5, 6. Since the material of the zipper tape 5 is a hot melt type adhesive resin, and the material of the zipper tape 6 is a polypropylene type resin, the heat sealing strength will be approximately 5 N/15 mm described above. This heat sealing strength of approximately 5 N/15 mm is of a degree that allows the zipper tapes to be peeled apart readily by hand.
  • a blue colouring agent is incorporated into the hot melt type adhesive resin which is the material forming the zipper tape 5
  • a yellow colouring agent is incorporated into the polypropylene type resin which is the material forming the zipper tape 6, so that when the respective zipper tapes 5, 6 are in a state of being bonded together by heat sealing, the colour of the bonding section becomes green, due to the mixing of the colours.
  • both of the zipper tapes 5, 6 from a transparent material, and performing coloration of the polyethylene type resin layer 7 and the hot melt type adhesive resin 8 provided on the outer sides thereof, using a blue colouring agent and a yellow colouring agent, respectively, it is possible to make the colour of the bonding section a green colour, by mixing the colours, similarly to the foregoing, when the two zipper tapes 5, 6 are bonded together by heat sealing.
  • hot melt type adhesive resin Various types of hot melt type adhesive resin are known, but in the present embodiment, it is possible to use, as a resin suitable for bonding the zipper tapes 5, 6 together in such a manner that they can be peeled apart by an interface peeling action, for example, a resin formed from a resin composition comprising at least one type of resin selected from a group comprising ethylene ethylacrylate copolymer comprising a main ingredient of ethylene vinyl acetate copolymer manufactured by Hirodine Corp., and petroleum resins, turpentine resins and rosin type resins.
  • a resin suitable for bonding the zipper tapes 5, 6 together in such a manner that they can be peeled apart by an interface peeling action for example, a resin formed from a resin composition comprising at least one type of resin selected from a group comprising ethylene ethylacrylate copolymer comprising a main ingredient of ethylene vinyl acetate copolymer manufactured by Hirodine Corp., and petroleum resins,
  • the material of the male zipper tape 5 is stated as a hot melt type adhesive resin
  • the material of the female zipper tape 6 is stated as a polypropylene type resin, but a reverse configuration is also possible.
  • a hot melt type adhesive resin layer is formed on the male zipper tape 5
  • a polyethylene type resin layer is formed on the female zipper tape 6.
  • a slider is provided on the zipper, but it is of course also possible to implement the present invention with a zipper having no slider.
  • a product (a bag containing contents) is arranged in a store display cabinet in a state in which the lower end sections of respective zipper tapes 5, 6 are bonded together with heat sealing strength of a degree that allows the bonding section of the zipper tapes to be readily peeled apart by hand, at the height of the bonding section of the tapes to the sheet sections 3, 4 of the packaging bag 1.
  • the colour (green) of the bonding section 9 will revert to the colours of the respective zipper tapes 5, 6 (blue, yellow) or, if the zipper tapes 5, 6 are transparent, it will revert to the colours of the polyethylene type resin layer 7 and the hot melt type adhesive resin layer 8 provided on the outer sides thereof. Hence it will be possible to confirm that the packaging bag 1 has been opened.
  • the heat sealing strength of the bonding section 9 between the zipper tapes 5, 6 is approximately the same as the heat sealing strength between the inner face of the packaging bag 1 and the female zipper tape 6 that is made of a polypropylene type resin and has a hot melt type adhesive resin layer 8 provided on the surface thereof. But since the bonding section 9 is situated at the lower end section of the location of the zipper tapes, the female zipper tape 6 and the packaging bag 1 are not liable to be peeled apart when the bonding section 9 is peeled apart by means of the user's fingers.
  • the zipper tape 5 is coloured blue and the zipper tape 6 is coloured yellow, in such a manner that the heat-sealed bonding section becomes green in colour, but it is also possible to use other colour combinations. It is not necessarily required to perform colouring of the zipper tapes 5, 6, and when the bonding section 9 of the zipper tapes 5, 6 has been peeled apart, it can be readily identified that the packaging bag 1 has been opened.
  • the two zipper tapes 5, 6 are bonded together in such a manner that they can be peeled apart by means of an interface peeling action, with heat sealing strength of a degree that permits the tapes to be peeled apart manually, at a position below the engaging section 10 of the zipper tapes 5, 6. It is also possible to bond the zipper tapes together by means of an interlayer peeling action or a cohesive peeling action.
  • a hot melt type adhesive resin used for forming a cohesive peel it would be suitable to use a polymer alloyed resin containing a polyolefin known as VMX (registered trademark) manufactured by Mitsubishi Chemical Corp. as a main ingredient.
  • the polymer alloyed resin essentially consists of a multi-component polymer including a polyolefin resin which is grafted with a radical polymerisation monomer and contains a non-crystalline vinyl polymer in a uniform manner, and a polymer including polyolefin dispersed with styrene in the dispersion phase of polyolefin.
  • the packaging bag 1 is made from a synthetic resin fabricated from sheet sections 3, 4 having a two-layer structure comprising nylon film in the outer layers 3a, 4a and polyethylene film in the inner layers 3b, 4b, but the materials used are not limited in particular to these.
  • a synthetic resin film such as a polyethylene film or a polypropylene film, or the like, is used to fabricate the inner layers, due to the requirements of heat sealing, it is possible to use a material other than a synthetic resin, such as aluminium foil, paper, rayon paper, or the like, as a material to be laminated on the outer sides of the inner layers.
  • a polyethylene type resin layer 7 and a hot melt type adhesive resin layer 8 are formed respectively on the faces opposing the inner layers 3b, 4b of the respective sheet sections 3, 4 but whilst the hot melt type adhesive resin layer 8 provided on the side of the female zipper tape 6 made from a polypropylene type resin is required, it is possible to omit the polyethylene type resin layer 7 provided on the side of the male zipper tape 5 made from a hot melt type adhesive resin.
  • the male zipper tape or the female zipper tape from a hot melt type adhesive resin
  • the other zipper tape made from a polyethylene type resin since the other zipper tape made from a polyethylene type resin is of the same type as the polyethylene film on the inner layer 3b of the sheet section 3, it will fuse completely with same, and the zipper tape made from a hot melt type adhesive resin and the polyethylene film on the inner layer 4b of the sheet section 4 will be bonded together by a heat sealing strength of approximately 5 N/15 mm, similarly to the embodiment described above.
  • the heat sealing strength between the zipper tapes may also be approximately 5 N/15 mm, and the two zipper tapes may be bonded together on the basis of an interface peeling action, as in the embodiment described above, or a interlayer peeling action, or a cohesive peeling action.
  • a composition may also be adopted wherein one of the zipper tapes is made from a hot melt type adhesive resin, and the outer face of the other zipper tape is made from a polyethylene type resin, whilst the inner face thereof is made from a polypropylene type resin which is different to the material forming the inner layer of the packaging bag 1.
  • the zipper tapes 5, 6 are bonded by heat sealing to the inner faces of the respective sheet sections 3, 4 of the packaging bag 1, but it is also possible for the two zipper tapes 5, 6 to be installed on the inner faces of the respective sheet sections 3, 4 of the packaging bag 1 by being laid respectively over the inner faces of the sheet sections 3, 4 of the packaging bag 1 in a sheet state, and bonded to same, whilst the zipper tapes 5, 6 are in a molten state directly after molten extrusion.
  • Fig. 4 shows a second embodiment of the present invention.
  • the second embodiment illustrated in Fig. 4 is a modification of the first embodiment shown in Fig. 1 - Fig. 3.
  • the male zipper tape 5 and the hot melt type adhesive resin layer 8 provided on the outer face of the female zipper tape 6 are made entirely from a hot melt type adhesive resin
  • the male zipper tape 5 is made from a polyethylene type resin of the same kind as the inner layer 3b of the packaging bag 1
  • the female zipper tape 6 is made from a polypropylene type resin
  • a section 12 made from a hot melt type adhesive resin being provided on the inner face of the male zipper tape 5 only in the vicinity of the bonding section 9 between the zipper tapes 5, 6, and a section 13 made from a hot melt type adhesive resin bonded to the inner layer 4b of the packaging bag 1 being provided on the outer face of the lower end section of the female zipper tape 6.
  • Fig. 5 shows a third embodiment of the present invention.
  • the male zipper tape 5 and the female zipper tape 6 are both made from a polyethylene type resin of the same type as forming the inner layers 3b, 4b of the packaging bag 1, and a section 14 made from a hot melt type adhesive resin is provided on the inner face of the female zipper tape 6, only in the vicinity of the bonding section 9 of the zipper tapes 5, 6.
  • both the zipper tapes 5, 6 are made from a resin containing a random mixture of a straight-chain type low-density polyethylene resin and a polybutene-1 resin, for example, as means for bonding the zipper tapes 5, 6 together in a readily peelable manner, in a position below the engaging section 10, with heat sealing strength of a degree that allows the zipper tapes to be manually peeled apart.
  • the bonding section 9 along the lower end section of the zipper tapes 5, 6 fabricated from the foregoing material will not couple completely, and hence it will be possible to peel apart the bonding section 9 of the zipper tapes 5, 6, readily and manually, by means of a cohesive peeling action.
  • Fig. 6 shows a fourth embodiment of the present invention.
  • both of the zipper tapes 5, 6 are made from a polyethylene type resin of the same type as forming the inner layers 3b, 4b of the packaging bag 1, and resin sections 15, 16 containing a resin comprising a random mixture of a straight-chain low-density polyethylene type resin and a polybutene-1 resin are provided on the inner faces of the two zipper tapes 5, 6 at least in the vicinity of the bonding section 9 located below the engaging section 10 of the zipper tapes 5, 6. This also causes the bonding section 9 in the lower end section of the zipper tapes 5, 6 not to couple together completely, and hence it will be possible to peel apart the bonding section 9 of the zipper tapes 5, 6 readily and manually by means of a cohesive peeling action.
  • the respective zipper tapes 5, 6 may have a structure comprising three or more layers.
  • a adhesive resin a material other than a polyethylene type resin or a polypropylene type resin, a hot melt type adhesive resin, or a resin containing a random mixture of a straight-chain type low-density polyethylene type resin and a polybutene-1 resin.
  • the bonding section 9 of the zipper tapes 5, 6 is bonded with a heat seal strength of approximately 5 N/15 mm, but it may be sufficient if the heat sealing strength is 1 N/15 mm or above.
