Packages having separable sealing features and methods of manufacturing
View Patent ↗A package includes a first pouch and either a second pouch or a cover, where the pouches are configured to contain a product, such as a food product, and attached relative to each other about a hinge. The package includes at least one closure flap. The first and second pouches or first pouch and cover are movable about the hinge from a closed position where access is at least partially blocked by the closure flap toward an open position where the closure flap is separated to allow greater access. Methods of manufacturing such packages are also provided.
1. A film package comprising:
a rear panel;
a front panel connected to the rear panel about a fold to form a bottom of the package, side seals between the front and rear panels, and a free edge of the front panel, opposite the bottom of the package, being unadhered to the rear panel so as to define a pouch with an interior configured to contain a product; and
an exterior wall pivotally connected to the rear panel about a hinge, an inner surface of the exterior wall having an adhesive attachment via a peelable seal to an outer surface of the front panel at the side seals, the exterior wall being detachable from the front panel at the peelable seal and without detaching along a line of weakness upon initial opening to provide access to the interior of the pouch in response to movement of the exterior wall about the hinge and away from the front panel, the exterior wall having a free edge that is generally aligned with the bottom of the package when the package is in a closed configuration;
wherein the inner surface of the exterior wall and the outer surface of the front panel are further interconnected by a pressure-sensitive adhesive area separate from the peelable seal and located between the peelable seal and the free edge of the exterior wall, the pressure-sensitive adhesive area being configured to detachably attach the inner surface of the exterior wall to the outer surface of the front panel to reclose the pouch after initial opening;
wherein the rear panel has a maximum height defined by a distance between the bottom of the package and the hinge and the front panel has a maximum height from the bottom of the package to the free edge of the front panel, the maximum height of the rear panel being greater than the maximum height of the front panel.
2. The package of claim 1 , wherein the peelable seal between the inner surface of the exterior wall and the outer surface front panel extends between the side seals.
3. The package of claim 1 , wherein one portion of the inner surface exterior wall directly overlies a portion of the outer surface of the front panel and another portion of the inner surface of the exterior wall directly overlies a portion of the product in the pouch.
4. The package of claim 2 , wherein the outer surface of the front panel includes a non-adhesive area between the peelable seal and the free edge of the front panel.
5. The package of claim 1 , wherein the exterior wall includes an arcuate pull tab configured to permit the exterior wall to be detached from the front panel by movement of the pull tab away from the bottom of the package and toward the hinge, a portion of the pull tab being spaced further from the hinge as compared to adjacent portions of the pull tab and portions of the exterior wall adjacent the pull tab.
6. The package of claim 5 , wherein the front panel includes an arcuate indentation in a direction away from the hinge configured to expose more of the product.
7. A method of manufacturing the package of claim 1 , the method comprising:
providing material having first and second longitudinal edges and a longitudinally extending fold zone;
depositing a product on the material between the longitudinally extending fold zone and the first longitudinal edge;
folding the second longitudinal edge of the material to overlay part of the product;
forming end seals between overlying portions of the film to form the pouch;
folding the first longitudinal edge of the material about the hinge to overlay at least another part of the product and the second longitudinal edge of the material;
detachably attaching a portion of the material including the first longitudinal edge to an underlying portion of the material including the second longitudinal edge; and
singulating the package.
