Abstract

A package, such as a bag or stand-up pouch, is described that includes a built-in opening support that can be actuated by the user to maintain the package in an open or wide-open configuration, thereby preventing or reducing the need to manually keep the front and back panels of the package separated as product is accessed. The opening support may be disposed near the opening end of at least one of the front or back panels and may be designed to be moved from an inactive position to an active position. In the inactive position, the opening support is disposed along one of the front panel or the back panel, whereas in the active position, the opening support extends between the front panel and the back panel, across a corresponding longitudinal seam of the package, to maintain the opening of the package in a wide-open position.

First claim

What is claimed is:

1. A method of manufacturing a package including an opening support, the method comprising:
forming a front panel defining an opening end, a base end, and two side edges;
attaching a back panel defining an opening end, a base end, and two side edges to the front panel via longitudinal seams formed along respective side edges of the front and back panels; and
disposing an opening support proximate the opening end of at least one of the front or back panels, the opening support configured to be moved from an inactive position to an active position,
wherein the opening end of the front panel and the opening end of the back panel define an opening of the package configured to provide access to contents of the package when the package is opened by a user,
wherein, in the inactive position, the opening support is disposed along one of the front panel or the back panel,
wherein, in the active position, the opening support extends between the front panel and the back panel, across a corresponding longitudinal seam, to maintain the opening of the package in a wide-open position,
wherein the opening support comprises a flexible strip of material defining a first end and a second end, wherein, in the inactive position, the first end is fixedly attached to one of the front panel or the back panel and the second end is removably attached to the same one of the front panel or the back panel, and wherein, in the active position, the second end is configured to attach to the other of the front panel or the back panel, such that the flexible strip of material spans the corresponding longitudinal seam, and
wherein an outer surface of a respective one of the front or back panels to which the second end is configured to removably attach includes a receiving feature configured to engage the second end.

2. The method of claim 1 , wherein the second end of the flexible strip includes pressure sensitive adhesive configured to removably attach the second end of the flexible strip of material to a respective one of the front or back panels.

3. The method of claim 1 , wherein the receiving feature includes a protrusion that extends outwardly from the outer surface of the respective one of the front or back panels, and the flexible strip further includes an indentation in the second end of the flexible strip configured to engage the protrusion of the receiving feature in the active position.

4. The method of claim 1 , further comprising a base panel connecting the base end of the front panel to the base end of the back panel, such that the package is a stand-up pouch.

5. The method of claim 1 , wherein the receiving feature comprises a removable flap that includes a region of pressure sensitive adhesive configured to removably attach to the second end of the flexible strip of material in the active position.

6. The method of claim 1 , wherein the receiving feature comprises a protrusion, and wherein the second end of the flexible strip of material includes an indentation configured to engage the protrusion of the receiving feature in the active position.

7. A method of manufacturing a package including an opening support, the method comprising:
forming a front panel defining an opening end, a base end, and two side edges;
attaching a back panel defining an opening end, a base end, and two side edges to the front panel via longitudinal seams formed along respective side edges of the front and back panels; and
disposing an opening support proximate the opening end of at least one of the front or back panels, the opening support configured to be moved from an inactive position to an active position,
wherein the opening end of the front panel and the opening end of the back panel define an opening of the package configured to provide access to contents of the package when the package is opened by a user,
wherein, in the inactive position, the opening support is disposed along one of the front panel or the back panel,
wherein, in the active position, the opening support extends between the front panel and the back panel, across a corresponding longitudinal seam, to maintain the opening of the package in a wide-open position
wherein the opening support is disposed on an inner surface of the package, and
wherein the opening support comprises a rigid member defining a fixed end and a free end.

8. The method of claim 7 , wherein the free end is configured to engage a receiving member disposed on the other of the front or back panels when the opening support is in the active position.

9. The method of claim 8 , wherein the receiving member comprises a groove configured to receive the free end of the rigid member to lock the rigid member in the active position.
