Definitions

  • the present invention relates, in general, to the packaging art, and, more particularly, is concerned with a package having a reclosable plastic zipper at its mouth and including tamper-evident features which provide a clear visual indication of the integrity of the package.
  • a typical plastic zipper has a groove along one side of the bag mouth and a rib along the other side, the rib interlocking into the groove when the two sides of the mouth of the bag are pressed together.
  • a member having a plurality of ribs may be on one side of the bag mouth, while a member having a plurality of channels may be on the other side, the ribs locking into the channels when the sides of the mouth of the bag are pressed together.
  • the ribs may simply be the intervals between the channels on a strip which may lock into one of the same kind.
  • seals of this type are formed across the mouth of the package by polymeric resin materials which seal the opening closed, but which are easily broken when the two sides of the package are pulled apart at the opening.
  • the material used to form the peel seal that is, the peel-seal material, whitens or otherwise discolors when broken, thereby giving a visual indication that the integrity of the package has been compromised.
  • the present invention represents an alternate approach toward providing a reclosable package with a tamper-evident feature.
  • the present invention is a reclosable package for the retail display of a food product and for the purchase and storage thereof by a consumer.
  • the package comprises a front sheet and a back sheet of thermoplastic sheet material.
  • the front and back sheets define the package having a top, a bottom, a first side and a second side.
  • the front sheet has a line of weakness running transversely thereacross at the top of the package.
  • the front and backs sheets are connected to one another along the bottom and first and second sides of the package.
  • the back sheet may be thermoformed to provide a compartment for a food product within the package.
  • a zipper is disposed transversely across the package between the front and back sheets and sealed thereto at the top of the package to provide it with a reclosable opening.
  • the zipper comprises two interlocking profiles, each of which is integrally formed with a web, one of the webs being sealed to the front sheet and the other being sealed to the back sheet.
  • the zipper is disposed such that the interlocking profiles are above the line of weakness relative to the top of the package, while the web sealed to the front sheet is so sealed below the line of weakness.
  • the front and back sheets are connected to one another above the zipper with a peel seal to form a header from which the package may be hung for retail display.
  • the peel seal and the line of weakness in the front sheet below the interlocking profiles provide the package with tamper-evident features.
  • FIG. 1 is a frontal plan view of the thermoform-fill-and-seal (TFFS) package 10 of the present invention
  • Figure 2 is a cross-sectional view thereof taken as indicated by line 2-2 in Figure 1.
  • the package 10 comprises a front sheet 12 and a back sheet 14, the latter of which may be thermoformed to provide a compartment 16 for a food product.
  • Both the front sheet 12 and the back sheet 14 may be extruded from a thermoplastic resin material, such as polyethylene, and may, depending on the process used to manufacture the package, have been physically part of a single sheet at the beginning of the manufacturing process.
  • a zipper 18, comprising two interlocking profiles 20,22, each of which is integrally formed with a web 36, and having a slider 24, runs across the top of the package 10 and provides it with a reclosable opening.
  • the front sheet 12 and the back sheet 14 form a header 26, from which the package 10 may be hung for display at a retail outlet.
  • a hole 28 may be punched through the header 26.
  • the front sheet 12 and the back sheet 14 are attached to one another with a peel seal, except at one corner 30, where the two sheets 12,14 are not joined to one another. This allows the consumer to grasp the front and back sheets 12,14 separately at the corner 30 to pull the two sheets 12,14 apart to gain access to the zipper 18 and ultimately to the contents of the package 10.
  • they may be separated, that is, not peel-sealed to one another, at some other portion of the header 26, such as across the top of the header 26.
  • a line of weakness 32 which may be a line of perforations, a score formed by some cutting device, or a line of reduced thickness.
  • the line of weakness 32 enables the front sheet 12 portion of the header 26 to be torn from the package 10 when the package 10 is first being opened by the consumer in the manner described in the preceding paragraph.
  • Both the peel seal joining the front and back sheets 12,14 at the header 26 and the line of weakness 32 provide the package 10 with tamper-evident features to alert the consumer that the package 10 may have been opened prior to purchase.
  • the front sheet 12 and the back sheet 14 may be joined to one another by hermetic peel seal 34 within the package 10 to provide an additional tamper-evident feature, as well as to ensure that no air can be exchanged between the inside and outside of the package 10.
  • hermetic peel seal 34 may be broken by pulling the front and back sheets 12,14 apart at the mouth of the package 10, giving the consumer access to its interior.
  • both of the interlocking profiles 20,22 of the zipper 18 are integrally formed with webs 36 extending toward the interior of the package 10.
  • Each of the front and back sheets 12,14 is sealed to the web 36 immediately adjacent thereto with seal 38, the web 36 attached to the front sheet 12 being so attached below (to the right of) line of weakness 32.
  • the package 10 is sealed along the sides and the bottom, which is on the right-hand side of both Figures 1 and 2, with seals 40,42,44,
  • the front and back sheets 12,14 wrap around the zipper 18 to form a pocket 46.
  • the size of the pocket 46 may be chosen advantageously to minimize any wrinkling of the front and back sheets 12,14.
  • the pocket 46 may also be sized advantageously to provide easy finger access by which to operate the slider 24 on the interlocking profiles 20,22.
  • back sheet 14 may be sealed to web 36 extending from profile 22 at a point close to interlocking profiles 20,22 to make it easier for a consumer to hold and pull the slider 24.
  • FIG. 3 A method for making the TFFS package 10 of the present invention is shown schematically in Figure 3, where the process proceeds from left to right.
  • back sheet 14 is dispensed from roll 48.
  • Heating device 50 heats the back sheet 14 so that it may be thermoformed at point 52 to provide the compartment 16.
  • a food product may be dispensed into the compartment 16 at point 54.
  • Zipper 18 including interlocking profiles 20,22, each of which is integrally formed with a web 36, is dispensed continuously from spool 56, and, at point 58, deformed at intervals equal to the width of the package 10 being produced to limit the movement of the sliders 24 that are being added at point 60.
  • the sliders 24 may optionally be moved to some preselected position on the zipper 18 at point 62 if desired.
  • the zipper 18 is united with the thermoformed back sheet 16 at point 64 and attached by sealing the web 36 of one of the interlocking profiles 20,22 thereto.
  • the ends of the zipper 18 may be deformed at the sides of the packages 10 being manufactured at point 66.
  • Front sheet 12 is dispensed from roll 68.
  • Device 70 which may be a perforator, scorer or laser heating device, is used to provide a lengthwise line of weakness 32 on front sheet 12.
  • the front sheet 12 is united with the zipper 18 and back sheet 14 at point 72, air is evacuated from the package 10 and the front and back sheets 12,14 are sealed together as previously described.
  • the front sheet 12 is disposed such that the line of weakness 32 is adjacent the zipper 18 with the interlocking profiles 20,22 being above the line of weakness 32 relative to the tops of the packages 10 being produced, and the web 36 of the other of the interlocking profiles 20,22 is sealed to the front sheet 12 below the line of weakness 32.
  • the front and back sheets 12,14 are also sealed to one another above the interlocking profiles 20,22 with a peel seal. Subsequently, the packages 10 are trimmed in the machine direction, if necessary, and are cut from one another in the cross-machine direction, the machine direction being the direction in which the process proceeds and the cross-machine direction being transverse thereto.
  • thermoform-fill-and-seal (TFFS) package and toward the TFFS package itself, it may be applied to the manufacture of packages according to other methods used in the industry.
  • TFFS thermoform-fill-and-seal
  • Figure 4 a method for making a similar, although not thermoformed, package on a horizontal-form-fill-and-seal (HFFS) machine is shown schematically in Figure 4.
  • thermoplastic sheet 80 is dispensed from roll 82.
  • a lengthwise line of weakness 84 is provided along one side of the sheet 80, or a sheet 80 already having a lengthwise line of weakness 84 is used.
  • the lengthwise line of weakness 84 could be provided substantially down the center of the sheet 80, or a sheet 80 already having such a lengthwise line of weakness 84 could be used.
  • a food product 86 is placed on the sheet 80 at intervals corresponding to the width of the packages being produced.
  • the sheet 80 is then folded lengthwise over the food product 86 at point 88.
  • zipper 18 including interlocking profiles 20,22, each of which is integrally formed with a web 36, is dispensed continuously from spool 90, and, at point 92, deformed at intervals equal to the width of the packages being produced to limit the movement of the sliders 24 that are being added at point 94.
  • the sliders 24 may optionally be moved to some preselected position on the zipper 18 so produced at point 96 if desired.
  • zipper 18 is fed between the front sheet and back sheet obtained by folding sheet 80, and thereafter, at point 100, is attached to the front and back sheets as previously described.
  • the zipper 18 is fed such that the line of weakness 84 is adjacent the zipper 18 with the interlocking profiles 20,22 being above the line of weakness 84 relative to the tops of the packages 10 being produced, and with the sheet having the line of weakness 84 being sealed to the web of one of the two interlocking profiles 20,22 below the line of weakness 84, while the sheet not having the line of weakness 84 is sealed to the web of the other of the two interlocking profiles 20,22.
  • the front and back sheets are also sealed to one another above the interlocking profiles 20,22 with a peel seal.
  • cross seals 102 are formed, and the packages so obtained are separated from one another at the cross seals 102.
  • thermoplastic sheet 104 is dispensed from roll 106.
  • a lengthwise line of weakness 108 is provided along one side of sheet 104, or a sheet 104 already having a lengthwise line of weakness 108 is used.
  • the sheet 104 is formed into the shape of a tube by the collar 110 of the fill tube 112 of the vertical form-fill-and-seal machine 114.
  • zipper 18 including interlocking profiles 20,22, each of which is integrally formed with a web 36, is dispensed continuously from a spool, and is deformed at intervals equal to the width of the packages being produced to limit the range of movement of the sliders 24 that may be added. As before, the sliders 24 may optionally be moved to some preselected position on the zipper 18.
  • the zipper 18 is fed between the two edges of the tube formed by folding sheet 104 around the fill tube 112 at point 116, and is attached to the two edges at point 118 as previously described. Specifically, the zipper 18 is fed such that the line of weakness 108 is adjacent the zipper 18 with the interlocking profiles 20,22 being above the line of weakness 108 relative to the tops of the packages 10 being produced, and with the edge having the line of weakness 108 being sealed to the web of one of the two interlocking profiles below the line of weakness 108, while the sheet not having the line of weakness 108 is sealed to the web of the other of the two interlocking profiles 20,22.
  • the edges of the tube formed by folding sheet 104 are also sealed to one another above the interlocking profiles 20,22 with a peel seal.
  • the packages being produced are sealed in the crosswise direction by transverse sealing bars 120, each package being filled with the food product of interest through fill tube 112 after each cross seal is made. Subsequently, each of the packages so obtained is separated from the next at the cross seals.
  • thermoplastic sheet 122 is dispensed from roll 124.
  • Lines of weakness 126 are provided transversely across sheet 122 for approximately one half of its width, or a sheet 122 already having such lines of weakness 126 is used.
  • the lines of weakness 126 are centered with respect to the two lateral edges of the sheet 122.
  • zipper 18 including interlocking profiles 20,22, each of which is integrally formed with a web 36, is dispensed continuously from spool 128, and is deformed at intervals equal to the width of the packages to be produced, that is, approximately one half of the width of the sheet 122, to limit the range of motion of the sliders 24 that are being placed thereon. As before, the sliders 24 may optionally be moved to some preselected position on the zipper 18.
  • the zipper 18 is then cut at the deformed points, and attached to the sheet 122 adjacent to the lines of weakness 126. Specifically, the cut zipper intervals are sealed to the thermoplastic sheet 122 adjacent and substantially parallel to each of the lines of weakness 126 with the webs 36 being on one side of the lines of weakness 126 and the interlocking profiles 20,22 being on the other side of the lines of weakness 126.
