Abstract

A wound package construct includes a first wound strip of package material that establishes an inner liner layer, a second wound strip of material that establishes an intermediate bodystock layer, and a third wound strip of material or cover strip that covers a seam formed by the wound bodystock layer but that does not cover all of the outer surface area of the wound bodystock layer. Therefore, the width of the cover strip is less than the width of the bodystock strip. As a result, the cover strip is not wide enough to cover the entire outer surface of the wound bodystock layer such that, after the cover strip is wrapped to cover the spiral bodystock seam, areas of the bodystock layer remain exposed between the two opposed length-wise edges of the cover strip.

First claim

The invention claimed is:

1. A wound package construct comprising:
a liner strip wound as a liner layer, the liner strip including two opposed liner edges, the opposed liner edges meeting at a spiral liner seam to form the liner layer having an interior side and an exterior side;
a bodystock strip wound as a bodystock layer on the exterior side of the liner layer, the bodystock strip including two opposed bodystock edges, the opposed bodystock edges meeting at a spiral bodystock seam to form the bodystock layer having an interior side and an exterior side;
a liner adhesive, provided between the exterior side of the liner layer and the interior side of the bodystock layer, bonding the liner layer and the bodystock layer;
a cover strip spirally wound on the exterior side of the bodystock layer and covering the spiral bodystock seam, the cover strip including adjacent cover strip edges that do not meet and do not overlap so as to remain spaced apart between the wound cover strip such that portions of the bodystock layer are exposed between the adjacent cover strip edges when the cover strip is fully wound on the bodystock layer; and
a cover adhesive, provided between the exterior side of the bodystock layer and an interior side of the cover strip, bonding the cover strip and the bodystock layer to establish a container.

2. The package construct of claim 1 , wherein the liner strip comprises a length having a uniform width between the two opposing liner edges, the uniform width being in a range from 2 to 6 inches.

3. The package construct of claim 2 , wherein the bodystock strip comprises a length having a uniform width between the two opposed bodystock edges, the uniform width being in a range from 2 to 6 inches.

4. The package construct of claim 3 , wherein the uniform width of the bodystock strip is approximately 4 inches.

5. The package construct of claim 3 , wherein one of the two opposed bodystock edges abuts another of the two opposed bodystock edges without overlapping.

6. The package construct of claim 1 , wherein one of the two opposing liner edges overlaps another of the two opposing liner edges at the spiral liner seam.

7. The package construct of claim 1 , wherein the cover strip comprises a length having a uniform width in a range from 1 to 3 inches.

8. The package construct of claim 7 , wherein the uniform width of the cover strip is approximately 1.5 inches.

9. The package construct of claim 7 , further comprising: a label layer, exterior to each of the liner layer, the bodystock layer and the cover strip, the label layer being removable to expose both the cover strip and the portions of the bodystock layer.

10. The package construct of claim 9 , wherein the label layer constitutes a sleeve positioned over the cover strip.

11. The package construct of claim 1 , further comprising a raw dough provided in the container against the interior side of the liner layer, with the raw dough being under pressure, wherein the container is configured to be opened by applying pressure to the cover strip at the spiral bodystock seam, without removing the cover strip, to cause failure of the cover adhesive bonding the bodystock and the cover strip, and by applying further pressure to the spiral bodystock seam to open the container along the bodystock seam to allow removal of the raw dough.

12. The package construct of claim 1 , further comprising a raw dough provided in the container against the interior side of the liner layer, with the raw dough being under pressure, wherein the container is configured to be opened by unwinding the cover strip to expose the bodystock seam, and then applying pressure to the spiral bodystock seam to open the container along the bodystock seam to allow removal of the raw dough.

13. A method of opening the container formed from the package construct of claim 1 comprising:
without removing the cover strip, applying pressure to the cover strip at the spiral bodystock seam to cause failure of the cover adhesive bonding the bodystock layer and the cover strip; and
applying further pressure to the spiral bodystock seam to open the container along the bodystock seam.

14. A method of opening the container formed from the package construct of claim 1 comprising:
unwinding the cover strip to expose the bodystock seam; and
applying pressure to the spiral bodystock seam to open the container along the bodystock seam.

15. A method of preparing a food package comprising:
spirally winding a liner strip to form a liner layer, the liner strip including opposed liner edges meeting at a liner seam to form the liner layer;
spirally winding a bodystock strip to form a bodystock layer on an exterior side of the liner layer, the bodystock strip including opposed bodystock edges meeting at a bodystock seam; and
spirally winding a cover strip over the bodystock seam on an exterior side of the bodystock layer, with the cover strip having adjacent cover strip edges which do not overlap so as to remain spaced apart such that portions of the bodystock layer are exposed between the adjacent cover strip edges to establish a container.

16. The method of claim 15 , further comprising:
placing liner adhesive between the liner layer and the bodystock layer; and
placing cover adhesive between the cover strip and the bodystock layer.

17. The method of claim 15 , further comprising, in spirally winding the liner strip, overlapping one of the opposing liner edges at the liner seam.

18. The method of claim 15 , further comprising: placing a dough composition within the container.

19. The method of claim 15 , wherein the bodystock strip which is spirally wound includes a length having a uniform width in a range from 2 to 6 inches between the opposed bodystock edges, and wherein the cover strip which is spirally wound includes a length having a uniform width in a range from 1 to 3 inches between the adjacent cover strip edges.

20. The method of claim 19 , wherein the uniform width of the bodystock strip is approximately 4 inches and the width of the cover strip is approximately 1.5 inches.
