  • first and second side gusset panel sections 18,20 are appropriately folded between the top end portions of first and second panel sections 14, 16.
  • Heat seals are appropriately applied to create flap 54. That is, heat seals are applied at side edges 58,60 and at top location 64 which is approximately an equal distance on the other side of aperture 56 from the top edge 26.
  • Bottom gusset panel section 22 is perforated, as illustrated by distribution apertures 66, as shown particularly in FIGS. 3 and 4.
  • Apertures 66 are appropriately sized, and there is a selected number of apertures per unit area in order to provide desirable passage of dispersible material 12.
  • An aperture 66 is shown to be circular, but other shapes are also possible. The sizes and shapes of the apertures are preferably sized for the type and characteristics of the dispersible material 12 which will be filled in bags 10 and appropriately dispersed.
  • Removable panel layer 68 is affixed to outer surface 52 of bottom gusset panel section 22.
  • Panel layer 68 covers apertures 66 and prevents leakage of dispersible material 12 from bag 10 before it is desired to disperse material 12.

  • Pouch arrangements according to the present invention may be provided with a variety of outer dimensions, depending on the intended use.
  • Pouch arrangements according to the present invention may be manufactured from a variety of materials. It is particularly advantageous, however, that they be constructed from relatively thin, strong material such as polyester biaxially oriented nylon linear low density polyethylene (PET/BON/LLDPE) film. Preferred embodiments which are particularly useful, and which include advantages according to the present invention, may be constructed wherein the first and second panel sections 14, 16 and the first and second gusset panel sections 18,20 comprise first and second sheets of PET/BON/LLDPE 3-ply, each having a thickness within a range of about 7 mils. Similar material may be utilized for the base gusset (with appropriate apertures or slits therein).
  • PET/BON/LLDPE polyester biaxially oriented nylon linear low density polyethylene
  • Preferably heat sealable film is utilized, so that the means for securing the various panel sections to each another, and securing the bottom gusset section in place, is by heat seals without the need for additional adhesive.
  • the film materials are available in 3 substrates and are laminated together in a conventional adhesive lamination process.
  • the polyester substrate has an adhesive applied, then the nylon substrate is applied.
  • the polyester substrate and nylon substrate are laminated together. This resulting layer is coated with the linear low density polyethylene substrate, and then laminated together.

  • the third substrate linear low density polyethylene
  • the top of bag 10 is open and dispersible material 12 is directed into the bag as shown in FIG. 2.
  • First and second gusset panel sections 18,20 are then folded near the top and first and second panel sections 14,16 are brought together and the appropriate heat sealing as described previously, is done to create flop 54 as shown in FIG. 1.
  • advertising or promotional material can be applied or associated with the bag, the bag is then displayed, and in due time the bag is sold to a consumer.
  • the bag When sufficient dispersion has been applied, the bag is tipped upside down and bottom gusset panel section 22 is folded or rolled from one of its edges toward an opposite of its edges so that all apertures are covered. Tape section 70 is removed from first panel section 14. Tape section 70 is then fastened to one of first and second panel sections 14,16 and to a portion of either bottom gusset panel section 22 or the other of first and second panel sections 14,16, as shown in FIG. 5.
  • FIGs. 6 and 7 A second embodiment is illustrated in FIGs. 6 and 7.
  • Bag construction 100 is essentially the same as bag construction 10, except for removable panel layer 102.
  • Removable panel layer 68 as shown in FIG. 3, is affixed at all four edges with a releasable adhesive so that it can be completely removed before dispersion.
  • Removable panel layer 102 is affixed at one edge 104 by a heat seal or other permanent attachment. The affixation of the other edges 106, 108,110 is by a releasable adhesive.
  • panel layer 102 In use, when dispersion of dispersible material 12 is desired, panel layer 102 is pulled away from bottom gusset panel section 22 at the edges 106,108,110 held by adhesive and is folded about the heat seal at edge 104. As shown in FIG. 8A, panel layer 102 may be temporarily affixed to, for example, second panel section 114 so that angle panel 102 is out of the way during dispersion of the dispersable material.
  • bottom gusset panel section 22 can be folded and panel layer 102 extended beyond bottom gusset panel section 22 opposite edge 104 panel layer 102 having the heat seal, so that edge 108 can contact and adhere to first panel section 116 as shown in FIG. 8B.

Abstract

L'invention concerne une structure de sac rempli de matériau dispersible, qui présente une première et une seconde section panneau, une première et une seconde section soufflet latérale et une section panneau de soufflet de fond. Les diverses sections panneaux sont fixées ensemble de façon à présenter une forme généralement rectangulaire à fond plat. La section de panneau de soufflet de fond présente une ou plusieurs ouvertures de distribution. Une couche de panneau amovible permet de recouvrir ces ouvertures. Lorsque la couche de panneau amovible est enlevée, le sac peut être tenu de façon à verser le matériau dispersible par lesdites ouvertures, le cas échéant.
