Definitions

  • This disclosure concerns reclosable packages and their use.
  • this disclosure describes flexible, reclosable packages having slider devices for opening and closing the packages, and a tamper-evident structure for indicating whether access has been gained into the package.
  • Flexible packages in particular resealable and recloseable packages, are frequently used for packaging of consumable goods. Goods that are not used completely when the package is initially opened rely on a zipper closure to reclose the package and keep the remaining contents fresh. Examples of consumable goods that are often packaged in packages, such as bags, with a zipper closure include potting soil, fertilizer, pet food, dog biscuits, vegetables, cereal, and many different foods edible by humans.
  • the opening and closing of the zipper closure is facilitated by a slider device that is mounted on the zipper closure.
  • the slider device is constructed to pry apart the interlocking zipper closure members when the slider device is moved in a first direction along the zipper, and to engage the interlocking zipper closure members when the slider device is moved in a second, opposite direction along the zipper.
  • a tamper-evident structure to notify whether access has been gained to the zipper closure, is desired. Improvements in these types of packages are desirable.
  • the present disclosure relates to a package, such as a flexible bag, having a resealable, reclosable zipper mechanism, opening and closing of which is accomplished by a slider device mounted on the zipper mechanism.
  • a tamper-evident structure is provided on the exterior of the zipper profile and the slider device so as to provide evidence whether access has been gained to the interior of the package.
  • the package has a first, zipper storage configuration and a second, zipper exposed or zipper operable configuration.
  • a tamper-evident structure When in the zipper storage configuration, a tamper-evident structure, together with at least one side panel of the package, form a pocket for enveloping at least a portion of the zipper closure and the slider device.
  • the tamper-evident structure When in the zipper exposed configuration, the tamper-evident structure is removed and the slider device is operable to open and close the zipper closure.
  • the package is transformed from the zipper storage configuration to the zipper exposed configuration by removing the tamper-evident structure and removing the zipper closure from the pocket.
  • the present disclosure is directed to a flexible, reclosable package having a surrounding wall which defines an interior and a mouth of the package, the mouth providing access to the interior.
  • a zipper closure having first and second releasably interlocking closure profiles, is disposed at the mouth.
  • a slider device is operably mounted on the zipper closure; the slider device is constructed and arranged to interlock the first closure profile with the second closure profile when the slider device is moved in a first direction, and to disengage the first closure profile from the second closure profile when the slider device is moved in a second opposite direction.
  • a tamper-evident structure is removably attached to the surrounding wall; and a pocket is defined by the tamper-evident structure and a portion of the surrounding wall.
  • the package is transformable from a zipper storage configuration to an operable configuration.
  • the storage configuration includes the zipper closure being enveloped in the pocket and the tamper-evident structure being removably attached to the surrounding wall; whereas the operable configuration includes the tamper-evident structure being removed from the surrounding wall and the zipper closure being exposed to permit operation of the slider device.
  • the package includes a first fold in the surrounding wall. This first fold positions the zipper closure and slider device, so that when the package is in the storage configuration, the zipper closure and slider device are displaced approximately 180 degrees from their position when in the operable configuration.
  • the package includes a first fold and a second fold. The two folds position the zipper closure and slider device, so that when the package is in the storage configuration, the zipper closure and the slider device are displaced approximately 360 degrees from, or are parallel to, their position when in the operable configuration.
  • a method of using a flexible, reclosable package having a zipper storage configuration and a zipper operable configuration.
  • the package has a surrounding wall which define an interior and a mouth, the mouth providing access to the interior, and a zipper closure disposed at the mouth.
  • a slider device is operably mounted on the zipper closure.
  • the package further has a pocket defined by a tamper-evident structure and a portion of the surrounding wall.
  • the package is transformable from the zipper storage configuration to the operable configuration; the storage configuration includes the zipper closure being enveloped in the pocket; and the operable configuration includes the tamper-evident structure removed and the zipper closure being exposed to permit operation of the slider device on the zipper closure.
  • the method comprises transforming the package from the zipper storage configuration to the operable configuration by removing the tamper-evident structure to provide access to the pocket; and removing the zipper closure from the pocket.
  • a slider device to a flexible package, such as a bag
  • a flexible package such as a bag
  • a slider device is advantageous to aging or arthritic persons not having the physical ability to use just a zipper closure to reseal a bag.
  • the addition of a slider device to a flexible package facilitates the use of the bag by users of all ages and abilities.
  • the addition of tamper-evident structure to a flexible package improves the security of the contents within the package interior, because the tamper-evident structure provides an indication whether access has been gained to the interior.
  • FIGS. 1 and 2 A flexible, reclosable package 10 is shown in FIGS. 1 and 2, in a configuration referred to as a "zipper storage" configuration.
  • Package 10 has a surrounding wall 13 defining an interior 11, as best seen in FIG. 2.
  • surrounding wall 13 comprises first and second polymeric film side panels 12 and 14, which surround and define interior 11.
  • Package 10 includes three edges, side edges 22, 24 (FIG. 1) and bottom edge 26, where the surrounding side panels 12, 14 connect to each other to form interior 11 of package 10.
  • first side edge 22 and second side edge 24 are seals created by the application of heat and pressure to side panels 12, 14.
  • Bottom edge 26 is a fold line between side panels 12, 14, which is formed when a single sheet of film is folded to form the two side panels 12, 14.
  • first and second panel sections 12, 14 are folded at side edges 22, 24 and heat-sealed at bottom edge 26; typically, such a package includes a fin seal (not shown) within one of panel sections 12, 14.
  • the panel sections 12, 14 are folded at one side edge, for example, first side edge 22, and heat-sealed at second side edge 24 and at bottom edge 26.
  • two separate panel sections 12, 14 of plastic film may be used and heat-sealed together along both side edges 22, 24 and at the bottom edge 26.
  • a zipper closure arrangement 30 having mating closure profiles to open and close (unseal and reseal) the first and second side panels 12, 14 of package 10 extends at least partially between side edge 22 and side edge 24 at mouth edge 28 (FIG. 1).
  • mouth edge 28 is disposed between side panels 12, 14 and recessed in toward interior 11.
  • Top edge 25 is the edge of package 10 farthest from bottom edge 26; in FIGS. 1 and 2, top edge 25 is a fold 15 in either or both side panels 12, 14.

  • First closure profile 32 and second closure profile 34 engage and disengage, as appropriate, to open and close package 10 and provide access to interior 11.
  • First and second closure profiles 32, 34 of zipper closure 30 are attached to side panels 12, 14, respectively, by sealing flanges 33, 35, which are connected to side panels 12, 14 at sealing areas 36, 38 as depicted in FIG. 2.
  • zipper closure 30 may be integral with surrounding wall 13, in particular, with side panels 12, 14; that is, first closure profile 32 and second closure profile 34 can be co-extruded, already attached to side panels 12, 14.
  • a slider device 40 is mounted on zipper closure 30 to facilitate opening and closing of zipper closure 30; in particular, slider device 40 engages and disengages first and second closure profiles 32, 34.
  • Slider devices and how they function to open and close zipper closures, in general, are taught, for example, in U.S. Patent Nos. 5,063,644; 5,301,394; 5,442,837, and 5,664,329, each of which is incorporated by reference herein.
  • a preferred slider device is taught in U.S. patent applications 09/365,215 and 29/108,657, both filed July 30, 1999 and incorporated herein by reference in their entirety.
  • slider device 40 is preferably constructed and arranged in accordance with the disclosures of the patent applications 09/365,215 and 29/108,657.
  • a notch (not shown) can be disposed within zipper closure 30.
  • a notch is designed to provide a "park place” into which slider device 40 settles when zipper closure 30 is sealed. Such a notch may decrease any tendency for an incomplete interlock between first closure profile 32 and second closure profile 34. Examples of notches are disclosed, for example, in U.S. Patent Nos. 5,067,208 and 5,301,395, each of which is incorporated by reference herein.
  • Package 10 as shown in FIGS. 1 and 2 is in a "zipper storage” configuration because zipper closure 30 and slider device 40 are stored within pocket 20 (FIG. 2), as will be described below.
