FLEXIBLE PACKAGE
A package for retaining consumable products is formed by a planar sheet or web of a flexible material that is folded about a plurality of aligned products. The fold of the sheet defines one side edge of the package. The other three side edges of the package are formed by sealing the front and back panel portions of the sheet to one another. An opening mechanism is provided for exposing at least a portion of the products retained within the package. The opening mechanism may be provided along the folded side edge of the package, at a corner of the package, adjacent to one of the sealed side edges. Other forms of opening means may also be formed along one of the seal edges along with means for resealing the opened package.

The present disclosure claims the benefit of the filing date of provisional application Ser. No. 61/587,787, filed Jan. 18, 2012.
FIELD OF THE INVENTIONThe present disclosure relates to a package formed from a flexible sheet material for retaining one or more product therein.
BACKGROUND OF THE INVENTIONPackages made of flexible sheet materials are known. Such packages are formed to hold and retain a variety of products. Certain package forms may be easily opened, but are not always resealable.
Flexible packages for the storage of consumable products, such as chewing gum in the form of sticks or slabs, are known. One such package includes a folded sheet of flexible material. The folded edge of the sheet forms one side of the package, while the other sides are sealed together using an adhesive, a heat seal or the like. The products retained may be of similar shape and size, with the package surrounding and retaining the products in the aligned fashion.
SUMMARY OF THE INVENTIONIn accordance with the present disclosure a package for consumable products (or the like) is disclosed. The package is thrilled by a planar sheet or web that is folded about the products. The fold of the sheet defines one side edge of the package. The other three side edges of the package are formed by sealing the front and back panel portions to one another. Opening means is provided for exposing at least a portion of the products retained within the package.
The opening means may be provided along the folded side edge of the package, preferably at a corner of the package, adjacent to one of the sealed side edges. The opening means may also be formed along one of the seal edges. In addition, means for resealing the opened package may be provided adjacent the opening means.
Other features of the present invention and combinations of features will become apparent from the detailed description to follow, taken in conjunction with the accompanying drawings.
For the purpose of the present disclosure, drawings are provided that show various forms. It should be understood that the invention is not limited to the precise arrangements and instrumentalities shown in the drawings.
In the figures, where like numerals identify like elements, there is shown a number of embodiments of a package or pouch for consumable products, such as chewing gum sticks or slabs. As generally shown in

Referring again to
The sheet material 26 of the present embodiment, and the others discussed below, may take the form of a laminate material having multiple layers. One example of a laminate for the present purpose is a combination of polyethylene terephthalate (PET), foil and Surlyn material. (Surlyn is a registered trademark of E.I. duPont de Nemours and Company.) Alternatives to these materials include oriented polypropylene (OPP) as a substitute for the PET. The foil layer may be replaced by a metalized polyester (MPET). The Surlyn material may be replaced, for example, by a polyethylene having a low heat sealing temperature.
The combination of the PET and foil provide the strength necessary for retaining product. The Surlyn material is contemplated to be an extrusion coating on the inside of the foil. The Surlyn material is typically used as a food contact or seal layer in flexible packaging. In the contemplated embodiment, the Surlyn material is used to form heat seals along the three side edges 20, 22 and 24. The PET layer in the lamination may be about 48 gauge (ga). The thickness of the alternative OPP material is contemplated to be 60 ga. The foil layer maybe in the range of 50 to 100 ga. The Surlyn seal coating may be fairly thin, such as being about 25 ga. A “permanent” laminating adhesive may be used to secure the PET to the foil, and may be a urethane based adhesive product. Ink may be (reverse) printed on the inside surface of the PET material and covered by the foil. The score line is contemplated to extend through the PET material, but not onto the foil layer. Appropriate graphics may be provided to identify the opening mean and the contemplated method for opening the package. The printing may be provided on the PET material by means of a rotogravure process, which is presently preferred, by a flexographic printing process or by some other known method.

The present disclosure includes a number of exemplary embodiments. It should be understood by those skilled in the art from the foregoing that various other changes, omissions and additions may be made therein, without departing from the spirit and scope of the contemplated invention. The various embodiments are intended to provide a range of opening options for a folded-side, sealed or similar type package. The opening options have a number of individualized structures that are relatively simple to identify and that provide easy opening of the package and withdrawal of the product contents.
Claims
1. A package for retaining a product comprising:
- a planar sheet folded along a first edge and defining front and back panels about the products, the folded first edge of the sheet defining one side edge of the package,
- three side edges formed by sealing the front and back panels to one another, the folded edge and the three sealed side edges defining an interior package volume for storing product therein, and
- opening means formed on at least one of the side edges, the opening means for selectively exposing a portion of the product retained within the package volume.
2. The package as in claim 1 wherein the opening means is provided along the folded first edge.
3. The package of claim 2 wherein the opening means is provided inwardly on the side edge from a package corner defined by the folded first edge and one of the sealed side edges.
4. The package of claim 3 further comprising means for resealing the opened package, the resealing means provided adjacent the opening means.
5. The package of claim 3 wherein the opening means comprises a score line within the planer sheet, the score line formed for separation of a flap portion of the folded first edge, the separation of the flap portion creating a notch in a portion of the folded first edge for discharge of product from the package volume.
6. The package of claim 5 wherein the score line is curved and wraps over the folded first edge.
7. The package of claim 5 wherein the score line is formed such that the flap portion remains attached to the package after Separation along the score line.
8. The package of claim 7 further comprising means for resealing the flap portion after separation along the score line
9. The package of claim 8 wherein the resealing means is provided adjacent the opening means and inwardly of the package corner.
10. The package of claim 1 wherein the opening means is formed along one of the sealed side edges.
11. The package of claim 10 wherein the opening means is formed by a sealing void that is surrounded by the sealed portion of the one sealed side edge, and wherein the sealed portion is defined by a peelable seal.
12. The package of claim 11 wherein the peelable seal is formed by one of the following:
- heat sealing and pressure sensitive adhesive.
13. The package of claim 11 further comprising means for resealing the opened package, the resealing means provided adjacent the opening means.
14. A package for retaining a plurality of individual products in an aligned formation, the package comprising:
- a body portion formed from a planar sheet folded along a first edge and defining front and back panels, the folded first edge of the sheet defining one side edge of the body, and three side edges formed by sealing the periphery of the front and back panels to one another, the folded edge and the three sealed side edges defining a package volume for storing the aligned products therein, and
- an opening mechanism formed along the folded first edge for selectively exposing at least a portion of the aligned products retained within the package volume, the opening mechanism provided inwardly from a package corner defined by the folded first edge and one of the sealed side edges.
