Definitions

  • the present invention relates to reclosable plastic bags of the type in which perishable food products and other goods are packaged for sale to consumers in retail outlets. More specifically, the present invention relates to reclosable plastic bags manufactured and concurrently filled on horizontal or vertical form-fill-and-seal (FFS) machines, wherein a plastic interlocking zipper for each bag is disposed transversely relative to the direction of motion of the thermoplastic sheet material used to form the reclosable bags on the FFS machine.
  • FFS form-fill-and-seal
  • the present invention relates to improvements in the package-making art and may be practised in the manufacture of thermoplastic bags and packages of the kind that may be used for various consumer products, but which are particularly useful for food products which must be kept in moisture- and air-tight packages, free from leakage until initially opened for access to the product contents, which packages are then reclosable by zipper means to protect any remainder of the product therein.
  • US-A-4909017 discloses a method of attaching a zipper strip on a thermoplastic sheet.
  • the zipper strip has male and female interlocking profiles having webs of equal width. One web is sealed to the thermoplastic sheet, then the bag is formed and the other web is sealed to the sheet forming the other side of the bag.
  • WO97/06062 discloses a method wherein one of the interlocking profiles of the zipper strip has a wider web, but both webs are sealed to the thermoplastic sheet forming one side of the bag. The narrower web is in contact with the sheet when the wider web is sealed to it.
  • the present invention relates to the provision of a transverse zipper for reclosable plastic bags or packages being manufactured on either a horizontal or vertical FFS machine. More specifically, the present invention is both a zipper strip and a method for securing the zipper strip transversely across the thermoplastic sheet material from which reclosable bags are being produced on a FFS machine.
  • a method for attaching a zipper strip transversely on a sheet of thermoplastic sheet material for use in the production of plastic bags or packages having transverse zippers on a form-fill-and-seal machine, said sheet being advanced in amounts equal in length to that of the bags or packages to be manufactured, a length of zipper strip being attached each time said sheet is brought to rest comprises the steps of:
  • a method for manufacturing reclosable packages on a horizontal form-fill-and-seal machine comprises the steps of:
  • FIG. 1 is a cross-sectional view of a first embodiment of the zipper strip 10 of the present invention.
  • the zipper strip 10 comprises a male interlocking profile 12 and a female interlocking profile 14.
  • the male interlocking profile 12 includes a male interlocking member 16 which may have an arrowhead-shaped cross section or, as is shown in Figure 1, an asymmetrical arrowhead-shaped cross section, designed to make the zipper strip 10 easier to open from one side than from the other.
  • the female interlocking profile 14 includes a female interlocking member 18 comprising two inwardly curving members forming a receptacle or channel into which the male interlocking member 16 may be snappingly engaged.
  • Both the male and female interlocking profiles 12, 14 include webs coextruded with the male and female interlocking members 16, 18.
  • Web 20 of male interlocking profile 12 it may be observed, is wider than web 22 of female interlocking profile 14.
  • web 20 has a leading flange 24 and a trailing flange 26, which together make up the amount by which web 20 is wider than web 22.
  • the leading and trailing flanges 24, 26 are so called because, when zipper strip 10 is attached to a thermoplastic sheet material being fed into an FFS machine, the leading flange 24 "leads” the transversely attached zipper strip 10 toward the machine, and the trailing flange 26 "trails" or is last.
  • leading flange 24 resides inward of the mouths of the plastic bags or packages being manufactured and concurrently filled with a consumer product on an FFS machine. While the male interlocking profile 12 is shown to have both the leading and trailing flanges 24, 26, both flanges 24, 26 could alternatively be part of the female interlocking profile 14 instead.
  • the zipper strip 10 is disposed transversely across thermoplastic sheet material during the manufacture of plastic bags or packages on an FFS machine.
  • the zipper strip 10 is dispensed with male and female interlocking profiles 12, 14 joined as shown in Figure 1 onto thermoplastic sheet material with the male interlocking profile 12 resting thereupon.
  • Heat seal bars 28 or the like applied against the leading and trailing flanges 24, 26 as suggested by the arrows in Figure 1, seal the male interlocking profile 12 to the thermoplastic sheet material (not shown) without sealing web 22 of the female interlocking profile 14 to web 20 of the male interlocking profile 12.
  • Heat seal materials 30 may be applied to the outside of web 20 of male interlocking profile 12, including the outsides of the leading and trailing flanges 24, 26, as well as to the inside of the trailing flange 26 and to the outside of web 22 of the female interlocking profile 14, to facilitate their being sealed to thermoplastic sheet material.
  • the trailing flange 26 may also be separable from the rest of web 20 by perforations.
  • leading and trailing flanges 24, 26 are attached to thermoplastic sheet material before the sheet material reaches the shoulder on a vertical FFS machine, or before the sheet material enters the FFS machine. Later, when the sheet material is folded over to form a tube with lateral edges sealed in a fin or overlap seal, the sheet material is sealed to the inside of trailing flange 26, as well as to the outsides of both webs 20, 22, without sealing the facing portions of webs 20, 22 to one another.
  • Figure 2 is a cross-sectional view of a second embodiment of the zipper strip 40 of the present invention. Elements common to both zipper strip 40 and zipper strip 10 described above are identified in Figure 2 using the same reference numbers. A comparison between Figures 1 and 2 indicates that zipper strip 40 lacks a trailing flange 26, but is identical to zipper strip 10 in all other respects. As was the case with zipper strip 10, zipper strip 40 is disposed transversely across thermoplastic sheet material during the manufacture of plastic bags or packages on an FFS machine. Male interlocking profile 42 rests upon the thermoplastic sheet material.
  • leading flange 24 could alternatively be part of the female interlocking profile 14 instead.
  • Both zipper strips 10, 40 shown in Figures 1 and 2, respectively, may be extruded from a polymeric resin material, such as a low-density polyethylene (LDPE).
  • Heat seal materials 30 may be applied as shown by coextrusion or by coating following the extrusion of zipper strips 10, 40.
  • Ethylene vinyl acetate (EVA) copolymers may be used as the heat seal materials 30.
  • Figure 3 is a perspective view of an apparatus used to attach zipper strip 10 to thermoplastic sheet material 50, which is conveyed in the direction of the arrows thereon toward an FFS machine. Thermoplastic sheet material 50 is moved intermittently in increments equal in length to the length of the packages being produced.
  • zipper strip 10 is sealed transversely across the upwardly facing side thereof.
  • Zipper tape 10 is dispensed from a roll or other supply not shown in Figure 3, and fed through a stationary clamp 52, and through a reciprocating shuttle 54, which includes a clamp 56 and a guillotine 58, the latter of which is used to cut the zipper strip 10 when required.
  • Shuttle 54 reciprocates each time the thermoplastic sheet material 50 is momentarily brought to rest.
  • clamp 56 is closed onto zipper tape 10
  • stationary clamp 52 is open, so that shuttle 54 pulls a length of the zipper tape 10 from the roll.
  • the outward end of shuttle 54 is a probe 60, which allows the leading flange 24 and the trailing flange 26 of the zipper tape 10 to protrude from the sides thereof.
  • the shuttle 54 is in its retracted position.
  • the probe 60 extends into the space between the top sealing jaw 62 and its corresponding bottom sealing jaw 64, the latter of which is on the underside of the thermoplastic sheet material 50.
  • the leading and trailing flanges 24, 26 extend outward from between the top and bottom sealing jaws 62, 64.
  • heat seal bars 28 seal the flanges 24, 26 to the thermoplastic sheet material 50.
  • Jaws 62, 64 then are opened; guillotine 58 cuts the next length of zipper strip 10; clamp 56 is opened; and clamp 52 is closed.
  • shuttle 54 retracts to the position shown in Figure 3, while thermoplastic sheet material 50 moves a length equal to the length of a package being manufactured to repeat the process.
  • FIG 4 is a perspective view of an alternate apparatus used to attach zipper strip 10 to thermoplastic sheet material 50.
  • thermoplastic sheet material 50 is conveyed in the direction of the arrow thereon toward an FFS machine, and is moved intermittently in increments equal in length to the length of the packages being produced.
  • zipper strip 10 is sealed transversely across the upwardly facing side thereof.
  • Zipper strip 10 is dispensed from a roll or other supply not shown in Figure 4, being pulled therefrom by a first clamp 70, which reciprocates back and forth along mechanism 74 in step with a second clamp 72.
  • First and second clamps 70, 72 grasp leading flange 24 of zipper strip 10 to pull the zipper strip 10 transversely across the thermoplastic sheet material.
  • Second clamp 72 holds the zipper strip 10 in position while it is being sealed to the upwardly facing side of the thermoplastic sheet material 50.
  • a stationary guillotine 76 is used to cut the zipper strip 10 when required.
  • thermoplastic sheet material 50 is momentarily brought to rest, second clamp 72 brings a length of zipper strip 10 cut by stationary guillotine 76 transversely outward thereover to the position shown in Figure 4.
  • first clamp 70 moving in step with second clamp 72, moves a length of zipper strip 10 through guillotine 76.
  • Top sealing jaw 62 and its corresponding bottom sealing jaw 64 the latter of which is on the underside of the thermoplastic sheet material 50, seal the leading flange 24 and the trailing flange 26 of the zipper strip 10 thereto, while the second clamp 72 holds onto the leading flange 24.
  • first clamp 70 and second clamp 72 retract from the positions shown in Figure 4, the first clamp 70 retracting to a position adjacent to guillotine 76, and the second clamp 72 retracting upstream from the guillotine 76 along zipper strip 10.
  • Thermoplastic sheet material 50 then moves a length equal to the length of a package being manufactured to repeat the process.
  • Figure 5 is a perspective view of another apparatus used to attach zipper strip 10 to thermoplastic sheet material 50.
  • Thermoplastic sheet material 50 is conveyed in the direction of the arrow thereon toward an FFS machine, and, as before, is moved intermittently in increments equal in length to the length of the packages being produced.
  • zipper strip 10 is sealed transversely across the upwardly facing side thereof.
  • Zipper strip 10 is dispensed from a roll or other supply not shown in Figure 5, being pulled therefrom by a perforated belt 80 entrained about chambers 82, 84 attached to a vacuum or suction. Suction through the perforated belt 80 is used to transport the zipper strip 10.
  • thermoplastic sheet material 50 is momentarily brought to rest, perforated belt 80 draws a length of zipper strip 10 transversely across thermoplastic sheet material 50.
  • the leading flange 24 and the trailing flange 26 of the zipper strip 10 extend beyond the two sides of the perforated belt 80 and chamber 82, which extend into the space between the top sealing jaw 62 and its corresponding bottom sealing jaw 64, the latter of which is on the underside of the thermoplastic sheet material 50.
  • the leading and trailing flanges 24, 26 extend outward from between the top and bottom sealing jaws 62, 64. The vacuum is turned off when the jaws 62, 64 close, heat seal bars 28 seal the flanges 24, 26 to the thermoplastic sheet material.
  • the jaws 62, 64 are then opened, and the thermoplastic sheet material 50 is moved a length equal to the length of a package being manufactured.
  • the vacuum is then turned on; guillotine 86 cuts the zipper strip 10; and the perforated belt 80 draws the portion of zipper strip 10 transversely across the thermoplastic sheet material 50 to repeat the process.
  • FIG. 6 is a schematic view of a horizontal apparatus.
  • a roll 90 of thermoplastic sheet material 50 dispenses the sheet 50 intermittently in lengths equal to that of the packages being manufactured and filled.
  • a length of zipper strip 10 is applied by the zipper applicator 92, which may include any of the three apparatus described, to the centre of the sheet material 50, as shown in Figure 7, leaving sufficient material along the two lateral edges 96 of the sheet material 50 to fold over toward one another for joining in an overlap or fin seam.
  • An accumulator 94 is used to convert the intermittent motion of the thermoplastic sheet material 50 to a continuous motion.
  • a product conveyor 98 carries the product 99 to be packaged toward the wrapping machine 100, which comprises a forming area 102, a sealing area 104, and a cross-seal area 106.
  • the forming area 102 the two lateral edges 96 of the sheet material 50 are folded upward and around the product.
  • the sealing area 104 the two lateral edges 96 are sealed to one another with a fin or lap seal to form a continuous film tube with the product and zipper strips 10 inside.
  • the cross-seal area the webs of the zipper strip 10 are sealed to the sheet material 50, without sealing the webs to each other, and the packages are separated from one another along lines 112, and carried onward by the takeaway conveyor 108.
  • Figure 8 depicts package 110 formed in accordance with the above and containing therein the product 99.
  • the top (wide) flange 26 of one of the profiles is sealed to the portions of the film web forming the package bottom 114 as well as the package top 116.
