Tamper evident hybrid resealable container
The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.
1. A method for manufacturing a resealable package, the method comprising:
laminating a top film layer to a bottom film layer to form a multilayer film, wherein the film includes:
a releasably affixed portion, in which the top film layer and the bottom film layer may be separated from and resealed to each other, and
an unaffixed portion, in which the top film layer and the bottom film layer are separate from each other;
forming an overcut in the top film layer along at least a portion of an outer periphery of the releasably affixed portion of the film to form a flap and a film pull tab, wherein the film pull tab is disposed within the unaffixed portion;
forming an undercut in the bottom film layer along at least a portion of an inner periphery of the releasably affixed portion of the film;
providing a fibrous material layer shaped to form the resealable package with an interior cavity when erected and including an opening which provides access to the interior cavity of the resealable package when formed, wherein the opening matches the inner periphery of the releasably affixed portion of the film;
perforating the fibrous material to form a fibrous pull tab; and
adhering the fibrous material layer to the top film layer such that the opening is substantially aligned with the inner periphery of the releasably affixed portion and the fibrous pull tab is substantially aligned with and adhered to the film pull tab.
2. The method of claim 1 , further comprising:
erecting the resealable package to form the interior cavity for storing items; and
sealing the resealable package closed.
3. The method of claim 2 , wherein sealing the resealable package comprises hermetically sealing the resealable package.
4. The method of claim 3 , wherein hermetically sealing the resealable package comprises lining the interior cavity with the film.
5. The method of claim 1 , wherein the releasably affixed portion of the film comprises pressure sensitive adhesive applied between the top film layer and the bottom film layer.
6. The method of claim 1 , wherein the fibrous material layer comprises paperboard.
7. The method of claim 1 , wherein the multilayer film comprises a barrier layer.
8. The method of claim 1 , wherein the unaffixed portion is formed by deadening adhesives applied between the top film layer and the bottom film layer.
9. The method of claim 1 , wherein the fibrous pull tab comprises a tamper-evident feature.
10. The method of claim 9 , wherein the tamper-evident feature comprises a perforation feature formed in the fibrous material layer adjacent the opening, wherein the perforation feature is separable from the fibrous material layer and adhered to the unaffixed portion of the film to form a pull tab.
11. A resealable package, the package comprising:
a multilayer film including:
a top film layer laminated to a bottom film layer,
a releasably affixed portion, in which the top film layer and the bottom film layer may be separated from and resealed to each other,
an unaffixed portion, in which the top film layer and the bottom film layer are separate from each other,
an overcut formed in the top film layer along at least a portion of an outer periphery of the releasably affixed portion to form a flap and a film pull tab, wherein the film pull tab is disposed within the unaffixed portion, and
an undercut formed in the bottom film layer along at least a portion of an inner periphery of the releasably affixed portion; and
a fibrous material layer forming an interior cavity for storing items, comprising an opening which provides access to the interior cavity, and comprising a perforated fibrous pull tab wherein:
the opening is substantially aligned with the inner periphery of the releasably affixed portion of the film,
the fibrous pull tab is substantially aligned with the film pull tab,
the fibrous material layer is adhered to the top film layer, and
the unaffixed portion of the film is disposed in the location of the film pull tab.
12. The resealable package of claim 11 , wherein the resealable package is hermetically sealed.
13. The resealable package of claim 11 , wherein film covers the entire interior cavity of the fibrous material layer.
14. The resealable package of claim 11 , wherein the fibrous material layer comprises paperboard.
15. The resealable package of claim 11 , wherein the releasably affixed portion of the film comprises pressure sensitive adhesive applied between the top film layer and the bottom film layer.
16. The resealable package of claim 11 , wherein the multilayer film comprises a barrier layer.
17. The resealable package of claim 11 , wherein the unaffixed portion is formed by deadening adhesives applied between the top film layer and the bottom film layer.
18. The resealable package of claim 11 , wherein the fibrous pull tab comprises a tamper-evident feature.
19. The resealable package of claim 11 , wherein the fibrous pull tab is disposed adjacent the opening in the fibrous layer.
20. The resealable package of claim 11 , wherein the fibrous material layer comprises the outermost layer of the package.
