Abstract

A resealable bag enclosure may be provided that includes a film having an opposing first side and second side coupled with each other, and a resealable zipper assembly coupled with the first side and the second side of the film. The first side and the second side of the film together may form a pattern at an opening stop location disposed between the first and second edges of the film and adjacent to an end of the zipper assembly. The pattern of the first side and the second side of the film may also resist opening of the resealable bag enclosure beyond the end of the zipper assembly when the first side and the second side of the film are pulled apart to prevent the peel seal from extending beyond the pattern.

First claim

What is claimed is:

1. A resealable bag enclosure comprising:
a film having a first side and an opposing second side coupled with each other along opposite first and second edges and a bottom edge that extends between the first and second edges;
a resealable zipper assembly coupled with the first side and the second side of the film,
wherein the first side and the second side of the film together form a zipper pattern at an opening stop location disposed between the first and second edges of the film and adjacent to an end of the resealable zipper assembly,
wherein the zipper pattern of the first side and the second side of the film resists opening of the resealable bag enclosure beyond the end of the resealable zipper assembly when the first side and the second side of the film are pulled apart; and
a peel seal formed between the first side and the second side of the film above the resealable zipper assembly, the first side and the second side of the film forming a peel seal pattern in the peel seal with the peel seal pattern in the peel seal oriented in a first direction that is different than a second direction of the zipper pattern of the resealable zipper assembly formed between the first side and the second side at the opening stop location to prevent the peel seal from extending beyond the peel seal pattern in the peel seal oriented in the second direction;
wherein the zipper pattern at the opening stop location is formed by one or more of 1) multiple intermeshing polygon members elongated in the first direction that is different from the second direction in which the resealable zipper assembly is elongated, 2) multiple intermeshing undulating members that are elongated in the first direction that is different from the second direction in which the resealable zipper assembly is elongated, or 3) the multiple intermeshing polygon members elongated in the first direction that is different from the second direction in which the resealable zipper assembly is elongated and the multiple intermeshing undulating members that are elongated in the first direction that is different from the second direction in which the resealable zipper assembly is elongated.

2. The resealable bag enclosure of claim 1 , wherein the resealable zipper assembly extends from the end of the resealable zipper assembly on the first side of the film to and around the first edge of the film and along the second side of the film to the end of the resealable zipper assembly.

3. The resealable bag enclosure of claim 2 , wherein the zipper pattern at the opening stop location is oriented perpendicular to the peel seal pattern in the peel seal.

4. The resealable bag enclosure of claim 2 , wherein the peel seal is configured to be broken to access the resealable zipper assembly by pulling apart the first side and the second side of the film to the opening stop location without tearing or removing any part of the film.

5. The resealable bag enclosure of claim 1 , further comprising:
plural relief areas in the film between the opening stop location and the second edge of the film, the relief areas including one or more of openings through the film or thinner areas of the film.

6. A resealable bag enclosure comprising:
a film having a first side and an opposing second side coupled with each other along opposite first and second edges and a bottom edge that extends between the first and second edges, the film having a peel seal between the first and second sides of the film and extending from the first edge of the film to an opening stop location; and
a resealable zipper assembly coupled with the first side and second side of the film, the resealable zipper assembly extending in a first direction on the first side of the film from an end of the resealable zipper assembly located adjacent to the opening stop location to and around the first edge and back to the end of the resealable zipper assembly along the first direction on the second side of the film, the resealable zipper assembly providing a resealable enclosure bounded by the first and second sides of the film, the first and second edges of the film, and the bottom edge of the film,
wherein the first side and the second side of the film form a pattern at the opening stop location, the pattern formed by elongated members in the first side and the second side of the film that are elongated in a second direction that is different from the first direction in which the resealable zipper assembly extends;
wherein the elongated members in the pattern at the opening stop location includes at least one of 1) multiple intermeshing polygon members, 2) multiple intermeshing undulating members, or 3) the multiple intermeshing polygon members and the multiple intermeshing undulating members.

7. The resealable bag enclosure of claim 6 , wherein the pattern formed by the opposite first side and second side of the film resisting opening of the resealable enclosure beyond the end of the resealable zipper assembly when the first side and the second side of the film are pulled apart.

8. The resealable bag enclosure of claim 6 , wherein the first side and second side of the film form a first pattern in the peel seal; wherein the pattern at the opening stop location is a second pattern at the opening stop location; and the first pattern in the peel seal having the elongated members in the peel seal elongated in a different direction than the elongated members in the second pattern at the opening stop location.

9. The resealable bag enclosure of claim 8 , wherein the elongated members in the second pattern at the opening stop location are elongated in the first direction that is oriented perpendicular to the second direction in which the elongated members are elongated in the first pattern in the peel seal.

10. The resealable bag enclosure of claim 6 , wherein the peel seal is configured to be broken to access the resealable zipper assembly by pulling apart the first side and the second side of the film to the opening stop location without tearing or removing any part of the film.

11. The resealable bag enclosure of claim 6 , further comprising:
plural relief areas in the film between the opening stop location and the second edge of the film, the relief areas including one or more of openings through the film or thinner areas of the film.

12. A resealable bag enclosure comprising:
a film having opposing sides coupled with each other along opposite first and second edges, and coupled with each other along a bottom edge that extends between the first and second edges, the film having a peel seal between the sides of the film and extending from the first edge of the film to an opening stop location, the film having first intermeshing members elongated in a first direction in the peel seal; and
a resealable zipper assembly coupled with the opposing sides of the film, the resealable zipper assembly extending from the first edge of the film along each of the resealable opposing sides to an end of the resealable zipper assembly at the opening stop location, the resealable zipper assembly providing access into an interior of the resealable bag enclosure;
wherein the opposing sides of the film form second intermeshing members elongated in a second direction that is different from the first direction in the opening stop location, the second intermeshing members restricting opening of the resealable bag enclosure beyond the end of the resealable zipper assembly.

13. The resealable bag enclosure of claim 12 , wherein the second intermeshing members are elongated in the second direction that is oriented perpendicular to the first direction in which the first intermeshing me
