Tamper-evident reusable package closure

1. A reusable closure system, comprising:

a base configured to be bonded to underlying package material and including a first field of touch fasteners having one or more cut-lines therein defining a hinged pull-tab assembly; and

a hinged lid configured for movement between open and closed positions relative to the base and including a second touch fastener field that is complementary to the first touch fastener field, such that the first and second touch fastener fields engage with one another to provide a secure closure when the lid is in the closed position;

wherein upon opening of the lid, the hinged pull-tab assembly is exposed so that the pull-tab assembly can be selectively peeled back to its hinge while simultaneously removing a frangible region of the packaging material to which the base can be bonded to form a resulting hole in the packaging material, and so that the peeled-back pull-tab assembly can be securely stowed against the lid by operation of the first and second touch fastener fields thereby providing a lid-based plug configured to engage the resulting hole in the packaging material when the lid is in the closed position.

2. The system of claim 1 wherein the first and second touch fastener fields comprise at least one of hook and loop fastener elements.

3. The system of claim 1 wherein the first touch fastener field comprises loop fastener elements, and the second touch fastener field comprises hook fastener elements.

4. The system of claim 1 wherein prior to its initial opening, the hinged pull-tab assembly comprises one or more tamper-evident features that visually indicate the hinged pull-tab assembly has not been opened.

5. The system of claim 1 wherein the hinged pull-tab assembly comprises a non-stick tab area that can be grabbed to peel back the hinged pull-tab assembly.

6. The system of claim 1 wherein the hinged pull-tab assembly comprises a multi-prong hinge.

7. The system of claim 6 wherein the multi-prong hinge has two prongs.

8. The system of claim 1 wherein the lid is further configured with one or more stay-open flaps that bias the lid to stay-open after the lid is opened.

9. The system of claim 1 further comprising one or more anti-peel features configured to prevent the hinged lid from being fully removed during opening.

10. The system of claim 1 further comprising one or more anti-peel features configured to prevent the hinged pull-tab assembly from being fully removed during opening.

11. The system of claim 1 wherein the one or more cut-lines therein defining the hinged pull-tab assembly are configured to provide a first hole that is larger than and surrounds the frangible region such that the resulting hole, after the frangible region is removed by operation of the pull-tab assembly, has a perimeter that is spaced inward from the perimeter of the first hole, thereby providing a seat for the lid-based plug.

12. The system of claim 11 wherein the seat for the lid-based plug includes deactivated adhesive.

13. The system of claim 11 wherein the seat for the lid-based plug includes a zone that is free of any adhesive deposition.

14. The system of claim 11 wherein the seat for the lid-based plug includes a bonding agent having holding power that is less than the holding power between the stowed pull-tab assembly and the lid.

15. A roll or fanfold of labels for use in a flow-wrap packaging process, wherein each label comprises the closure system of claim 1 .

16. 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; and

the closure system of claim 1 , wherein the base is bonded to the flexible sheet material such that the hinged pull-tab assembly is bonded to the frangible region;

wherein the base and hinged lid are of greater rigidity than the flexible sheet material.

17. The container of claim 16 , further comprising usable product within the interior volume and accessible via the frangible region once the pull-tab assembly has been stowed against the lid.

18. The container of claim 17 wherein the usable product comprises wet wipes.

19. A reusable closure system, comprising:

a base configured to be bonded to underlying package material and including a first field of touch fasteners having one or more cut-lines therein defining a hinged pull-tab assembly, wherein the hinged pull-tab assembly comprises a two-pronged hinge and a non-stick tab area that can be grabbed to peel back the hinged pull-tab assembly, and prior to its initial opening, the hinged pull-tab assembly further comprises one or more tamper-evident features that visually indicate the hinged pull-tab assembly has not been opened; and

a hinged lid configured for movement between open and closed positions relative to the base and including a second touch fastener field that is complementary to the first touch fastener field, such that the first and second touch fastener fields engage with one another to provide a secure closure when the lid is in the closed position;

wherein upon opening of the lid, the hinged pull-tab assembly is exposed so that the pull-tab assembly can be selectively peeled back to its hinge while simultaneously removing a frangible region of the packaging material to which the base can be bonded to form a resulting hole in the packaging material, and so that the peeled-back pull-tab assembly can be securely stowed against the lid by operation of the first and second touch fastener fields thereby providing a lid-based plug configured to engage the resulting hole in the packaging material when the lid is in the closed position; and

wherein the first touch fastener field comprises loop fastener elements, and the second touch fastener field comprises hook fastener elements.

20. A reusable closure system, comprising:

a base configured to be bonded to underlying package material and including a first field of touch fasteners having one or more cut-lines therein defining a hinged pull-tab assembly; and

a hinged lid configured for movement between open and closed positions relative to the base and including a second touch fastener field that is complementary to the first touch fastener field, such that the first and second touch fastener fields engage with one another to provide a secure closure when the lid is in the closed position;

wherein upon opening of the lid, the hinged pull-tab assembly is exposed so that the pull-tab assembly can be selectively peeled back to its hinge while simultaneously removing a frangible region of the packaging material to which the base can be bonded to form a resulting hole in the packaging material, and so that the peeled-back pull-tab assembly can be securely stowed against the lid by operation of the first and second touch fastener fields thereby providing a lid-based plug configured to engage the resulting hole in the packaging material when the lid is in the closed position;

wherein the one or more cut-lines therein defining the hinged pull-tab assembly are configured to provide a first hole that is larger than and surrounds the frangible region such that the resulting hole, after the frangible region is removed by operation of the pull-tab assembly, has a perimeter that is spaced inward from the perimeter of the first hole, thereby providing a seat for the lid-based plug; and

wherein the first touch fastener field comprises loop fastener elements, and the second touch fastener field comprises hook fastener elements.
