Definitions

  • the present invention relates to improving the leak-proof or spill-resistant quality of gussets in reclosable packages, particularly those made with multi-wall paper or woven polypropylene. This is achieved by sealing the gussets together through apertures in the gusset walls, by sealing the zipper flanges together through apertures passing through the gussets, or by sewing the gusset shut.
  • gussets can increase the tendency for the contents of the reclosable package or bag to leak from the gusset area proximate to the intersection of the package or bag walls and the zipper. More specifically, the contents can travel up the center of the package or bag, between the zipper profiles and out the gusset.
  • Figure 1 is a plan view, partially in phantom, of a prior art gusseted package or bag, showing the route through which contents may inadvertently escape.
  • Figure 2 is a cross-sectional view along plane 2-2 of Figure 1.
  • Figure 3 is a cross-sectional view along plane 3-3 of Figure 1.
  • Figure 4 is a perspective view of the expanded walls of the package or bag of the first embodiment of the present invention prior to the installation of the reclosable zipper.
  • Figure 5 is a perspective view, partially in phantom, of the collapsed walls of the package or bag of the first embodiment of the present invention prior to the installation of the reclosable zipper.
  • Figure 6 is a plan view, partially in phantom, of the package or bag of the first embodiment of the present invention after installation of the reclosable zipper. This plan view is likewise applicable to the second embodiment of the present invention.
  • Figure 7 is a perspective view, partially in phantom, of the expanded walls of the package or bag of the second embodiment of the present invention prior to the installation of the reclosable zipper.
  • Figure 8 is a perspective view, partially in phantom, of the collapsed walls of the package or bag of the second embodiment of the present invention prior to the installation of the reclosable zipper.
  • Figure 9 is a perspective view of the expanded walls of the package or bag of the third embodiment of the present invention prior to the installation of the reclosable zipper.
  • Figure 10 is a perspective view, partially in phantom, of the collapsed walls of the package or bag of the third embodiment of the present invention prior to the installation of the reclosable zipper.
  • Figure 11 is a plan view, partially in phantom, of the package or bag of the third embodiment of the present invention after installation of the reclosable zipper.
  • Figure 1 is a plan view, partially in phantom, of a prior art reclosable package or bag 100 and that Figures 2 and 3 are cross-sectional views thereof.
  • the package or bag 100 is formed from co-extensive front wall 102 and rear wall 104 which are typically formed from polymeric materials (such as, but not limited to, polyethylene or polypropylene, including woven polypropylene), multi-wall paper or laminates.
  • Gussets 106, 108 are formed as inwardly pointing folds between the side edges of front and rear walls 102, 104, typically integral with, or at least of the same material as, front and rear walls 102, 104.
  • Gusset 106 is formed from gusset walls 106a, 106b in an inwardly pointing V-shaped configuration while gusset 108 is formed from gusset walls 108a, 108b in an inwardly pointing V-shaped configuration.
  • the bottom edges of front and rear walls 102, 104 are sealed or otherwise closed or joined to form bottom 110. Mouth 112 is formed between the top edges of front and rear walls 102, 104.
  • Zipper assembly 200 is sealed, glued or otherwise secured to the upper exterior of front and rear walls 102, 104.
  • zipper assembly 200 includes first profile 202 and second profile 204.
  • First profile 202 includes first interlocking element 206 and first flange 210.
  • Second profile 204 includes second interlocking element 208 and second flange 212.
  • First and second flanges 210, 212 are sealed, glue or otherwise secured to the upper exterior of front and rear walls 102, 104, respectively.
  • zipper assembly 200 includes slider 214 mounted on first and second profiles 202, 204.
  • Slider 214 operates in a conventional manner of interlocking first and second interlocking elements 206, 208 with each other when moved in a first direction and separating first and second interlocking elements 206, 208 when moved in a second direction.
  • first and second interlocking elements 206, 208 may have a "press-to-close" configuration in which no slider is required.
  • this design is susceptible to contents within package or bag 100 traveling up the center of the package or bag 100, between the first and second flanges 210, 212 and out the gussets 106, 108. This leakage or spillage is illustrated for the first gusset 106 but is equally applicable to the second gusset 108. This deficiency can be minimized or eliminated by closing the gussets 106,
  • Figure 4 illustrates a first embodiment of the present invention wherein apertures 120, 122, 130, 132 are formed in gusset walls, 106a, 106b, 108, 108b, respectively.
  • apertures 120, 122 align with each other so that a portion of front wall 102 contacts a portion of rear wall 104 through the aligned apertures 120, 122.
  • apertures 130, 132 align with each other so that a portion of front wall 102 contacts a portion of rear wall 104 through the aligned apertures 130, 132.

  • the sealing can be heat sealing by ultrasonic or conduction, or can be by adhesive.
  • grommets (not shown) can pass through aligned apertures 120, 122 and 130, 132.
  • the resulting package or bag 100 is illustrated in Figure 6.
  • the parenthetical notations to numerals 118, 124, 128, 134 apply to the extent that Figure 6 likewise illustrates the second embodiment of the present invention.
  • Figure 7 illustrates a second embodiment of the present invention wherein apertures 118, 124 (in phantom) are formed in front and rear walls 102, 104 respectively, so as to align with apertures 120, 122.
  • apertures 128, 134 are formed in front and rear walls 102, 104, respectively so as to align with apertures 130, 132.
  • apertures 118, 120, 122, 124 align with each other.

  • the resulting package or bag 100 is illustrated in Figure 6, as is the first previously described first embodiment.

  • Figures 9 and 10 illustrate a third embodiment of the present invention wherein thread or similar material is used to form first and second stitches 150, 152.
  • First stitch 150 stitches together gusset walls 106a, 106b with the portions of front and rear walls 102, 104 which contact the gusset walls 106a, 106b.
  • second stitch 152 stitches together gusset walls 108a, 108b with the portions of front and rear walls 102, 104 which contact the gusset walls 108a, 108b.
