Pressure-sensitive adhesive and hook and loop fasteners (58) can be used lo reseal the package.
Description
- The invention relates to pour spouts for plastic or paper packages, either single or multi-ply. The invention also relates to a reclosable pour spout for bagged products. The invention further relates to a packages having a reclosable pour spout.
- Many foods, particularly pet foods, e.g., dog and cat foods, are packed in large bangs, i.e., 2-40 pound packages. These are difficult to open and also difficult to reclose. The reclosure is important because these foods contain fat which tends to oxidize on exposure to the air with resultant change in flavor which may make it unpalatable to pets.
- Attaching a pour spout to these packages is difficult because the bags often are paper with laminations of plastic to keep the fat in the product from emigrating to the outer surface of the bag and discoloring the surface with a grease stain. Once an opening is cut in the bag for the spout, the edges of the lamination are exposed to the product which is not acceptable. In these situations, it is necessary to apply a back seal to the spout opening in the package in addition to attaching the spout to the outside of the package.
- Other such packages are multi-ply plastic with a moisture and fat impervious layer or single ply plastic. In these situations the spout must have a high temperature resistant outer layer and a thermoplastic sealing layer around the edges to allow heat sealing the spout to the bag around the opening formed in the bag.
- Presently there are various methods to open bagged products. One of these is merely tearing or pulling apart the top of the bag. This approach is both crude and sometimes very difficult. Another method of opening a sealed bag is to cut across the top of the bag. This approach can be dangerous as it requires a sharp instrument. Some packages have a string sewn across the top of the bag or a string embedded in the top seam, across the top of the bag. These approaches too can be difficult and frustrating to open.
- Once opened, products that are capable of flowing can be poured from the tops of any of these bags. Control of the flow rate is limited and cumbersome because of the large opening across the entire top of the package.
- All of these packages also have re closing problems, depending on the material from which the bag is constructed. For example, multiply paper bags are usually reclosed by rolling or folding down the top of the bag. This method does not provide a very tight or effective reclosure.
- Most poly (plastic) bags are reclosed by folding down or rolling down the top of the bag. Like paper, this method does not provide a very tight or effective reclosure because poly has a very weak memory. Therefore, the rolled or folded reclosure tends to open. Recent developments have made zipper type reclosure features available for poly bags. This added feature has greatly improved the tightness of the reclosure. Another popular type of bag is a laminated package using polyester in combination with a variety of polyethylene options. Zippers are commonly used for reclosure. Without the zipper, the bag is subject to the same problems as reclosing the poly bag.
- Zippers are generally applied across the entire face of the bag. This construction makes it difficult for the consumer to achieve a tight reclose of the zipper across the entire width of the bag. The location and size of the zipper are not designed for or conductive to the pouring of product from the bag. In addition, the product can contaminate the zipper preventing reclosure. Also, zippers are not available for reclosing multi-ply paper bags.
- Thus, it is a principal object of this invention to provide a pour spout which can be attached to packaged products to facilitate opening the packages and pouring the products therefrom. It also is a principal object to provide a pour spout for bagged products which is easy to open and also is reclosable to reseal the contents of the bag from exposure to the atmosphere. A further object is to provide pour spout attachments which can be applied to plastic and paper cartons or bags, either single or multi-ply. Still another object, is to provide a pour spout having accordion pleated sides and hinged at one end to a package and movable from a closed to an open position for pouring and returnable to a closed position adjacent to the package where it can be fastened in said closed position. Still a further object is to provide bags having reclosable pour spouts attached thereto.
- These and other objects and advantages will become apparent hereinafter.
- The present invention comprises a pour spout hinged to a wall of a plastic or paper package such that it is opened to allow product to be poured from the package and when closed can be locked against the wall to seal the pour spout opening.
- The objects of the invention are achieved as set forth in the illustrative embodiments shown in the drawings which form a part of the specification and wherein like numerals refer to like parts wherever they occur.

- The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what we presently believe is the best mode of carrying out the invention. As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying, drawings shall be interpreted as illustrative and not in a limiting sense.
- FIG. 1 shows a package, namely a
bag 10, havinggusset ends 11, afront panel 12, abottom 13 and a double roll foldmaterial corner top 14. A pourspout assembly 20 of this invention is applied to onegusset end 11. The pourspout 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 pourspout assembly 20. Thebag 10 has anopening 15 preferably formed in one of theside gussets 11. Theopening 15 can be in the front or back wall of thebag 10, if desired. Theopening 15 is formed in thebag 10 during its manufacture prior to filling product into thebag 10. Theopening 15 is used as an outlet for the product contained in thebag 10, after the pourspout assembly 20 has been attached to thebag 10. - FIG. 3 shows the blank21 which forms the pour
spout assembly 20. The blank 21 has atop edge 22, side edges 23,24 and abottom edge 25 which define arectangular body area 26. Adjacent to and spaced inwardly from the side edges 23, 24 are verticalpermanent bond areas top edge 22 to thebottom edge 25. Adjacent to the bottom edge is a horizontalpermanent bond area 29 which extends along thebottom edge 25 and inwardly therefrom into theblank body 26. While we have referred toareas areas - The body blank26 preferably is a lamination as shown in FIG. 3a. The
outer layers center layer 32 is a paper or a paper aluminum foil composite. Thelayer 32 preferably is 20-50# kraft paper, but can be any material which will accept folding and remain in folded condition. Thelayers - Vertical inside
fold lines blank body 26 equidistantly spaced from the vertical centerline and parallel to the side edges 23,24. - The
inside fold lines inside bond edge 37 define aback wall panel 38 which forms the pour spout back wall. - Between the
inside fold line 35 and thepermanent bond area 27 are a series of equally spaced vertical fold lines 39. Between theinside fold line 36 and thepermanent bond area 28 are a series of equally spaced vertical fold lines 40. The fold lines 39 define a series of sidewall gusset panels 39 a-39 f. The fold lines 40 define a series of sidewall gusset panels 40 a-40 f. Thegusset panels 39 a-39 f have bottom areas 41 a-41 f which form a part of the horizontalpermanent bond area 29 and are coated with a heat sealable adhesive. Thegusset panels 40 a-40 f have a series of bottom areas 42 a-42 f which form part of thepermanent bond area 29 and are coated with a heat sealable adhesive. - Depending from the
top edge 22 of theback wall 38, is arectangular flap 45 which can be used to open the pour spout and to reclose it as will be explained hereinafter. - In forming the pour
spout 20 from the blank 26, the blank 26 is die cut and folded along thelines areas 41 c to 41 d; theareas 41 e to 41 f; the areas 42 a to 42 b; theareas 42 c to 42 d; and theareas 42 e to 42 f. - FIG. 4 shows the blank21 formed into the pour
spout assembly 20. It is thisassembly 20 which is positioned over theside panel opening 15. - FIG. 5 shows the pour
spout assembly 20 secured to theside panel opening 15. In this construction, theareas bag gusset end 11, preferably by heat sealing This seals the bottom and side edges of the pourspout 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 thebag 10 by a removableadhesive strip 56. Aremoval tab 57 is not glued to thebag 10 and is used to pull theoverseal 55 open. Theoverseal 55 also can be fabricated to be used to reclose and reseal the pourspout 20 as will be explained hereinafter. The tear seals 43 are of less width than theseals spout 20. The tear seals 43 preferably are used in combination with the tamperevident overseal 55. - Another method of resealing the pour spout is to place a strip of two-
sided tape 46 on thebag 10 above theopening 15. One side of thetape 46 is permanently secured to thebag 10. The other side of thetape 46 has arelease strip 47 covering a sticky pressure-sensitive adhesive surface. After the pourspout 20 is opened, therelease strip 47 can be removed and theflap 45 is resealed to the top surface of thetape 46 by pressing it against thetape 46. To open the pourspout 20, the flap is detached from thetape 46. - As noted, to reclose the pour
spout 20, theflap 45 is secured to thegusset end 11 by engagement with the pressure-sensitive tape 46 which is attached to thebag end 11. The side wall gusset panels 41 of the pourspout 20 are folded together when the assembly is in closed, non-pouring condition and are held thereto by the adhesive of theflap 45 to thetape 46. - Preferably, the pour
spout 20 is attached to thebag 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. - To activate the pour
spout 20 after theoverseal 55 is removed, thetop edge seal 43 is opened and theflap 45 andback wall panel 38 are pivoted outwardly and downwardly to expose theopening 15 to the inside of thebag 10. The contents of thebag 10 can be poured out of the pourspout assembly 20. - To reclose the
bag 10, theflap 45 is reengaged to the pressure-sensitive side of thestrip 46. - Another method for resealing is to make the overseal55 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 backwall 38 and to the bag along thebottom 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 thebag 10. The hook portion of the strip is attached to thespout tab 45. The hook portion is on the bag to prevent contamination when pouring the product. - The pour spout constructions shown in FIG. 1-5 are adaptable to both polymeric and paper bags. However, the manufacturing techniques for making a bag and pour spout combination are different for a paper bag and for a polymeric bag.
- In manufacturing the
bag 10 and pourspout assembly 20 when the bag is polymeric, thebag 10 has the cut out 15 formed in theside gusset 11, and the folded pourspout assembly 20 is attached around theopening 15 by activating thepermanent bonds removable seal 43 or theoverseal 25. - When the bag is paper, the edges of the cut out15 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. To seal off these edges, a
gasket 50 is heat sealed to the inside of thebag 10 around theopening 15. Theinner margin 51 of thegasket 50 extends into theopening 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 theopening 15 and to thegasket margin 51, thus effectively isolating the edges of theopening 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 thebag 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. - In fabricating the inside attachment, the
tab 45 is folded downwardly along theline 22 to fit thespout 20 through thepackage opening 15. Theedges package 10. Thetab 45 can be left in folded position or unfolded and sealed against the outside of thepackage 10 to seal the top of theopening 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.
- Thus it is seen that the present invention achieves all of the objects and advantages sought therefore and this invention is intended to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.
