Abstract

The present package is formed from a bag construct that entirely surrounds a blank construct and that can be folded from a flat configuration to a carton configuration. The blank construct has five sides, including four sides and a bottom side, and an open top. The bag construct surrounds all four sides, the bottom, and the open top. The package includes a dispensing flap that provides access to contents, and the dispensing flap can be hinged about a hinge line or that can be removed entirely from the package. Any variance in density of product in the package can be accommodated by the stiff, yet flexible, sides of the package.

Claims

1. A package comprising:

a bag;

a blank disposed in an interior of the bag;

the blank being fixedly attached to a portion of the bag;

the blank being foldable to define interior sides and an interior bottom of the package and the bag being foldable to define an exterior top, exterior sides, and an exterior bottom of the package; and

,

a dispensing flap in the bag defined by a first tear line and a second tear line in the exterior top and by a third tear line and a fourth tear line in at least one side of the exterior sides;

wherein the dispensing flap is separable along the first tear line, the second tear line, the third tear line, and the fourth tear line; and

wherein the dispensing flap can be hinged to allow the dispensing flap to be opened and reclosed.

2. The package of claim 1 wherein a hinge line is disposed in the exterior top.

3. The package of claim 2 wherein the hinge line is along and collinear with a fold line connecting the exterior top and a second exterior side of the bag.

4. The package of claim 2 wherein the dispensing flap is removable from the package along the hinge line.

5. The package of claim 1 wherein the bag entirely surrounds the blank.

6. The package of claim 1 wherein the dispensing flap comprises a substantial entirety of the exterior top.

7. The package of claim 1, wherein the blank comprises:

a plurality of panels comprising a bottom panel, a first side panel foldably connected to the bottom panel, a second side panel foldably connected to the bottom panel, a third side panel foldably connected to the bottom panel, and a fourth side panel foldably connected to the bottom panel;

wherein the bottom panel is fixedly attached to the interior of the bag.

8. The package of claim 7, wherein the fourth side panel is arranged substantially perpendicular to the bottom panel, and wherein the fourth side panel is arranged substantially parallel to a sealed end of the bag.

9. The package of claim 1, wherein the interior sides and the interior bottom of the package define an interior open top, and wherein the dispensing flap covers at least a portion of the interior open top.

10. A method of forming a package, the method comprising:

providing a blank and a bag, the blank including a plurality of side panels connected along fold lines to a bottom panel, the blank at least partially connected along a plurality of the series of side panels to the bag, with at least one side panel of the blank free from connections to the bag, the bag being foldable to define an exterior top, exterior sides, and an exterior bottom of the package, wherein the bag surrounds the blank and the bag includes a dispensing flap defined by a first tear line and a second tear line in the exterior top and by a third tear line and a fourth tear line in at least one side of the exterior sides;

folding the blank and bag from a flat configuration to a package configuration, wherein the folding comprises positioning the plurality of side panels of the blank substantially perpendicular the bottom panel, with two of the side panels being substantially parallel; and

,

closing the package by (1) folding the at least one side panel substantially perpendicular the bottom panel, and then (2) folding the bag into a closed configuration.

11. The method of claim 10 wherein the side panels of the blank, when folded in the package configuration, define an open top, and wherein the dispensing flap covers at least a section of one of the series of side panels and at least a portion of the open top.

12. The method of claim 10 wherein at least a portion of the blank is fixedly attached to the bag.
