Reusable closure system for packaging

A container defining an interior volume, the container comprising:

• flexible sheet material bounding at least one side of the interior volume and forming an outer surface of the container, the flexible sheet material having a frangible region;
• a base bonded to the flexible sheet material over the frangible region, the base further including first and second fields of touch fasteners separated by a multi-layer buffer zone that is at least in part co-located with the frangible region and substantially free of active bonding agent;
• and
• a hinged lid configured to open and close with respect to the base portion and to provide access to product within the container via the frangible region when the lid is open, the lid further including a third field of touch fasteners configured to engage at least one of the first and second touch fastener fields when the lid is closed;
• wherein the touch fasteners include at least one of hook and loop fastener elements;
• and
• wherein the base and hinged lid are of greater rigidity than the flexible sheet material.

A flexible reusable closure system for flexible packaging applications that include use of a frangible region to provide access to packaged product, the closure system comprising:

• a flexible base configured with adhesive for adhering the base to product packaging material, the base further including first and second fields of touch fasteners separated by a multi-layer buffer zone that is configured to keep the frangible region substantially free of active adhesive;
• and
• a flexible hinged lid configured to open and close with respect to the base portion and to provide access to the packaged product via the frangible region when the lid is open, the lid further including a third field of touch fasteners configured to engage at least one of the first and second touch fastener fields when the lid is closed;
• wherein the touch fasteners include at least one of hook and loop fastener elements;
• and
• wherein the first touch fastener field is bonded within an area defined by the frangible region, and the second touch fastener field at least partially surrounds the buffer zone.
