Definitions

  • the present invention relates to a method for attaching a reclosable zipper fastener to a flexible material.
  • Reclosable containers utilizing zipper-type fasteners are well known in the packaging industry and are used for holding, displaying and dispensing a wide variety of products ranging from hardware items to food products intended for human consumption.
  • the construction of virtually all such prior art fasteners comprises one or more female parts which releasably receive one or more corresponding male parts.
  • those portions of the fastener bearing the respective female and male parts must typically be attached to opposing sides of the container such that the female and male parts will be in registry with each other.
  • a typical such construction is disclosed in U. S. Patent No. 4,909,017 to McMahon and Dogr.
  • US 4 335 617 discloses a reclosable bag having elongated opening means adapted to be permanently opened with a slide fastener.
  • the present invention relates to a method according to claim 1.
  • a tamper-evident container formed from a flexible material and having a reclosable fastener is generally indicated as 10 in the views of Figs. 1 , 2 , 5 and 6 .
  • the reclosable fastener is generally indicated as 12.
  • fastener 12 comprises a pair of mating, reclosable sealing strips, generally indicated as 14 and 16, respectively.
  • Each of the sealing strips 14 and 16 comprise a base segment 18 and 20, respectively.
  • Base segment 18 is attached to interior surface 22 of flexible material 24, and base segment 20 is similarly attached to the common interior surface 22.
  • attachment of the fastener 12 to common interior surface 22 is indicated by perimeter seal 26.
  • removable portion 28 of flexible material 24 by which access to the interior of container 10 may be obtained once portion 28 is removed to form an aperture providing access to strips 14 and 16 whereby they may be separated from each other.
  • removable portion 28 is defined by a plurality of cuts formed through flexible material 24. These cuts comprise a plurality of perforations 30 and at least one slit 32, though a pair of opposed slits 32 are illustrated in the view of Fig. 6 .
  • Slit 32 provides a free segment of flexible material 24 whereby portion 28 may be removed to provide access to fastener 12.
  • the perforations 30 are preferably formed within the area defined by line A-A, and the slit, or slits, 32 are preferably formed within the area between arrows B.
  • sealing strip 14 further comprises a second segment 34 integrally formed therewith, but not attached to common interior surface 22.
  • Sealing strip 16 also comprises-a second segment 36 integral with its base segment 20, but not attached to common interior surface 22.
  • a female fastener part 38 is formed on second segment 34, and a corresponding male fastener part 40 is formed on sealing strip 16 at the juncture of base segment 20 with second segment 36.
  • container 10 further includes another segment of flexible material 24' forming another wall thereof, and a seam 42 is provided by the joining of flexible material 24 to a corresponding segment of flexible material 24'.
  • a similar seam 42' is formed at the bottom of container 10.
  • an hermetic seal is a particular advantage of this invention.
  • the perimeter seal 26 extends around the perimeter of fastener 12.
  • a broadened segment 44 can be seen at each end of perimeter seal 26.
  • Broadened segment 44 is frequently referred to in the packaging industry as a "splotch" seal.
  • a splotch seal involves the application of heat and pressure to the distal ends of sealing strips 14 and 16 so as to form a flattened, broadened segment 44.
  • an hermetic seal is formed in completely surrounding relation to the removable portion 28.
  • a second tamper-evident container is generally indicated as 10'.
  • second container 10' further comprises a tack seal 46 to bond second segment 34 to inside surface 48 of flexible material 24' forming the opposite side of container 10'.
  • tack seal 46 to bond second segment 34 to inside surface 48 of flexible material 24' forming the opposite side of container 10'.
  • first and second containers 10 and 10' respectively, attention is now invited to the following description of the method for attaching fastener 12 to a flexible material 24 for providing a tamper-evident reclosable opening therethrough.
  • a segment of flexible material 24 is selected for forming a container 10.
  • a plurality of cuts comprising perforations 30 and at least one slit 32 are made to define a removable portion 28.
  • a reclosable zipper-type fastener 12 is selected and cut to a predetermined length sufficient to overlie the removable portion 28.
  • Opposed distal ends of fastener 12 are then "splotched" and the splotched length of fastener is disposed in adjacent, overlying relation to removable portion 28.
  • the perimeter seal 26 is formed by the application of pressure and heat. If desired, tack seal 46 would be made in a subsequent step. From that point on, the container would be formed and filled using standard form and fill apparatus and methods. No further manipulation of fastener 12 and its related removable portion 28 is required.
