Best Mode for Carrying Out the Invention
  • Fig. 1 shows a package, namely a bag 10, having gusset ends
  • a pour spout assembly 20 of this invention is applied to one gusset end 11.
  • the pour spout 20 is shown in open or pouring position and is movable to closed position as shown by the arrow "A".
  • Fig. 2 shows the bag 10 prior to application of the pour spout assembly 20.
  • the bag 10 has an opening 15 preferably formed in one of the side gussets 11.
  • the opening 15 can be in the front or back wall of the bag 10, if desired.
  • the opening 15 is formed in the bag 10 during its manufacture prior to filling product into the bag 10.
  • the opening 15 is used as an outlet for the product contained in the bag 10, after the pour spout assembly 20 has been attached to the bag 10.
  • Fig. 3 shows the blank 21 which forms the pour spout assembly 20.
  • the blank 21 has a top edge 22, side edges 23,24 and a bottom edge 25 which define a rectangular body area 26. Adjacent to and spaced inwardly from the side edges 23, 24 are vertical permanent bond areas 27,28 which extend from the top edge 22 to the bottom edge 25. Adjacent to the bottom edge is a horizontal permanent bond area 29 which extends along the bottom edge 25 and inwardly therefrom into the blank body 26. While we have referred to areas 27,28,29 as permanent bond areas, practically the entire surfaces of the spout blank are of heat sealable material. Strip coating of the areas 27,28,29 can be used, however, this increases the cost and requires registering the cut with the coating during manufacture of the spout.
  • the body blank 26 preferably is a lamination as shown in Fig. 3a.
  • the outer layers 30,31 are moisture and oil impervious polyethylene and the center layer 32 is a paper or a paper aluminum foil composite.
  • the layer 32 preferably is 20-50# kraft paper, but can be any material which will accept folding and remain in folded condition.
  • the layers 30,31 preferably are high density polyethylene.
  • the blank 26 could be one piece provided the material is moisture and oil impervious and also will retain folds.
  • Vertical inside fold lines 35,36 are positioned in the blank body 26 equidistantly spaced from the vertical centerline and parallel to the side edges 23,24.
  • the inside fold lines 35,36 along with an inside bond edge ' 37 define a back wall panel 38 which forms the pour spout back wall.
  • the fold lines 39 define a series of side wall gusset panels 39a-39f.
  • the fold lines 40 define a series of side wall gusset panels 40a-40f.
  • the gusset panels 39a-39f have bottom areas 41a-41f which form a part of the horizontal permanent bond area 29 and are coated with a heat sealable adhesive.
  • the gusset panels 40a-40f have a series of bottom areas 42a-42f which form part of the permanent bond area 29 and are coated with a heat sealable adhesive.
  • a rectangular flap 45 which can be used to open the pour spout and to reclose it as will be explained hereinafter.
  • the blank 26 is die cut and folded along the lines 39,40.
  • the pleated sides are formed by adhering the areas 41a to 41b; the areas 41c to 41d; the areas 41e to 41f; the areas 42a to 42b; the areas 42c to 42d; and the areas 42e to 42f.
  • Fig. 4 shows the blank 21 formed into the pour spout assembly
  • Fig. 5 shows the pour spout assembly 20 secured to the side panel opening 15.
  • the areas 27,28,29 are permanently bonded to the bag gusset end 11 , preferably by heat sealing This seals the bottom and side edges of the pour spout assembly 20.
  • the top edge can be secured by removable tear seals 43; or in the alternative, the top edge can merely be held tightly by an overseal or tamper evident/product freshness overseal 55.
  • the overseal 55 is sealed around its periphery to the bag 10 by a removable adhesive strip 56.
  • a removal tab 57 is not glued to the bag 10 and is used to pull the overseal 55 open.
  • the overseal 55 also can be fabricated to be used to reclose and reseal the pour spout 20 as will be explained hereinafter.
  • the tear seals 43 are of less width than the seals 27,28 and consequently are easier to tear open to release the pour spout 20.
  • the tear seals 43 preferably are used in combination with the tamper evident overseal 55.
  • Another method of resealing the pour spout is to place a strip of two-sided tape 46 on the bag 10 above the opening 15.
  • One side of the tape 46 is permanently secured to the bag 10.
  • the other side of the tape 46 has a release strip 47 covering a sticky pressure-sensitive adhesive surface.
  • the release strip 47 can be removed and the flap 45 is resealed to the top surface of the tape 46 by pressing it against the tape 46.
  • the flap is detached from the tape 46.
  • the flap 45 is secured to the gusset end 11 by engagement with the pressure-sensitive tape 46 which is attached to the bag end 11.
  • the side wall gusset panels 41 of the pour spout 20 are folded together when the assembly is in closed, non-pouring condition and are held thereto by the adhesive of the flap 45 to the tape 46.
  • the pour spout 20 is attached to the bag 10 when the bag is fabricated at the bag plant. However, it also can be attached at the user's plant before the bag is assembled or filled.
  • the top edge seal 43 is opened and the flap 45 and back wall panel 38 are pivoted outwardly and downwardly to expose the opening 15 to the inside of the bag 10.
  • the contents of the bag 10 can be poured out of the pour spout assembly 20.
  • the flap 45 is reengaged to the pressure- sensitive side of the strip 46.
  • Another method for resealing is to make the overseal 55 from a pressure-sensitive material. This provides a three-sided re-seal for the consumer, namely, the top and two sides.
  • the overseal 55 will be permanently attached to the outside face of the spout back wall 38 and to the bag along the bottom edge 25.
  • Another method for resealing is shown in Fig. 7 and involves the use of a hook and loop fastener strip 58 sold under the trademark VELCRO.
  • the loop portion of the strip is attached to the bag 10.
  • the hook portion of the strip is attached to the spout tab 45.
  • the hook portion is on the bag to prevent contamination when pouring the product.
  • the manufacturing techniques for making a bag and pour spout combination are different for a paper bag and for a polymeric bag.
  • the bag 10 and pour spout assembly 20 when the bag is polymeric the bag 10 has the cut out 15 formed in the side gusset 11 , and the folded pour spout assembly 20 is attached around the opening 15 by activating the permanent bonds 27,28,29 and attaching the removable seal 43 or the overseal 25.
  • the edges of the cut out 15 must be sealed from contact with the contents of the package because the product in the bags can contain oils that might wick.
  • the opening cut into the bag exposes raw edges of the paper to the product.
  • a gasket 50 is heat sealed to the inside of the bag 10 around the opening 15.
  • the inner margin 51 of the gasket 50 extends into the opening 15 around the periphery. This is shown in Fig. 6.
  • the pour spout assembly then is heat sealed both to the outside of the bag around the opening 15 and to the gasket margin 51 , thus effectively isolating the edges of the opening 15.
  • the remainder of the assembly is similar to that hereinbefore described.
  • Fig. 8 shows another modification of the invention in which the pour spout 20 is mounted on the inside of the bag 10.
  • This provides a more eye appealing attachment, but practically some of the outer ply material on packages is very difficult, if not impossible to seal to.
  • the inside of a package typically is heat sealable.
  • the tab 45 is folded downwardly along the line 22 to fit the spout 20 through the package opening 15.
  • the edges 27,28,29 are heat sealed to the inside of the package 10.
  • the tab 45 can be left in folded position or unfolded and sealed against the outside of the package 10 to seal the top of the opening 15.
  • the invention has been disclosed specifically applied to the side gusset of a bag. However, it can be applied to a front or back wall of a bag or to a rigid or semi-rigid carton. These containers or packages can be of any shape or size that a consumer would lift and pour. While the invention is preferably applied to packages containing dry particulate product, the accordion pleated spout can be applied to packages containing liquid product.
