(a) the zipper-operable section includes a lower attachment region between the second seal flange and the second wall panel, and being between the second profile member and the closed bottom; and an upper attachment region between the second seal flange and the second wall panel, and being between the second profile member and the mouth.
3. A reclosable zipper pouch according to claim 2 wherein:
(a) the zipper-non-operable section includes at least a lower attachment region between the second seal flange and the second wall panel, and being between the second profile member and the closed bottom.
4. A reclosable zipper pouch according to claim 3 wherein:
(a) the second seal flange includes a die line substantially along a length of the second zipper profile between the first and second sides, and being between the second profile member and the mouth;
(b) the upper attachment region of zipper-operable section extends at least on the die line; and
(c) the zipper-non-operable section includes an upper attachment region between the second seal flange and the second wall panel, and being between the die line and the mouth; a region between the die line and the second profile member being free of attachment.
5. A reclosable zipper pouch according to claim 3 wherein:
(a) the zipper-non-operable section is free of attachment between the second seal flange and the second wall panel, and between the second profile member and the mouth.
6. A reclosable zipper pouch according to claim 1 wherein:
(a) the first seal flange is secured to the first wall panel adjacent along at least an upper attachment region between the first profile member and the mouth, and a lower attachment region between the first profile member and the bottom.
7. A method of making a reclosable zipper pouch, the method comprising:
(a) providing a surrounding wall having a closed bottom, first and second opposite sides, an open mouth, and first and second opposing wall panels between the first and second opposite sides;
(b) providing a first zipper profile including a first seal flange and a first profile member extending from the first seal flange and securing the first seal flange to the first wall panel adjacent to the mouth and between the first and second sides to provide the first profile member extending from the first seal flange toward the second wall panel;
(c) providing a second zipper profile including a second seal flange and a second profile member extending from the second seal flange and securing the second seal flange to the second wall panel adjacent to the mouth and between the first and second sides to provide the second profile member extending from the second seal flange toward the first wall panel and in a location to engage the first profile member; a first side seal attachment region being along the first side attaching the first zipper profile and second zipper profile along the first side; and a second side seal attachment region being along the second side attaching the first zipper profile and second zipper profile along the second side;
(i) the first and second profile members being constructed and arranged to selectively interlock when pressed together and unlock when forced apart;
(ii) the step of securing the second seal flange to the second wall panel includes securing the second seal flange at a zipper-operable section and a zipper-non-operable section;
(A) the zipper-operable section being constructed and arranged so that when a pulling force is applied at the zipper-operable section to the first and second zipper profiles, the first and second profile members will unlock; and
(B) the zipper non-operable section being constructed and arranged so that when a pulling force is applied at the zipper-non-operable section to the first and second zipper profiles, the first and second profile members will not unlock; the zipper non-operable section extending along at least half of the second zipper profile between the first side seal attachment region and the second side seal attachment region.
8. A method according to claim 7 wherein:
(a) the step of securing the second seal flange at a zipper-operable section includes securing a lower attachment region between the second seal flange and the second wall panel, and between the second profile member and the closed bottom; and securing an upper attachment region between the second seal flange and the second wall panel, and being between the second profile member and the mouth; and
(b) the step of securing the second seal flange at a zipper-non-operable section includes securing at least a lower attachment region between the second seal flange and the second wall panel and between the second profile member and the closed bottom.
9. A method according to claim 8 wherein:
(a) the step of providing a second zipper profile includes providing the second seal flange to include a die line substantially along a length of the second zipper profile between the first and second sides, and between the second profile member and the mouth;
(b) the step securing the second seal flange at a zipper-operable section includes securing the upper attachment region of the zipper-operable section at least on the die line; and
(c) the step of securing the second seal flange at a zipper-non-operable section includes securing an upper attachment region of the zipper-non-operable section between the second seal flange and the second wall panel, and between the die line and the mouth; a region between the die line and the second profile member being free of attachment.
10. A method according to claim 8 wherein:
(a) the step of securing the second seal flange at a zipper-non-operable section includes limiting the attachment of the second seal flange in the zipper-non-operable section to the lower attachment region and ensuring a region between the second profile member and the mouth in the zipper-non-operable section is free of attachment between the second seal flange and the second wall panel.
