Abstract
A recloseable zipper pouch includes a recloseable zipper with interlocking profiles. At least one of the profiles has a grasping flange with a free end positionable both above and below the interlocking profile, and an attachment flange below the interlocking profile and attached to the wall of the pouch at an anchored portion on the attachment flange. The grasping flange is unattached to the first wall between opposite sidewall edges of the pouch. The complementary interlocking profile is attached to the opposite pouch wall. Some pouches can also include an opening in a side wall of the pouch to provide access to a portion of the grasping flange.
Claims22
A recloseable package comprising:
- (a) a first and second sidewall joined along respective sidewall edges and a bottom to form a package with an open mouth;
- and
- (b) a recloseable zipper closure positioned adjacent the mouth, comprising:
- (i) a first track comprising an interlocking profile, the first track further comprising a grasping flange having a free end positionable both above and below the interlocking profile;
- and an attachment flange being below the interlocking profile, the first track attached to the first sidewall at an anchored portion on the attachment flange;
- the grasping flange being unattached to the first sidewall between the sidewall edges;
- and
- (ii) a second track comprising a complementary interlocking profile, the second track attached to the second sidewall;
- wherein the grasping flange is freely movable and unattached to the first sidewall a complete distance between the sidewall edges;
- and wherein when the package is in a closed condition with the interlocking profiles mated, a surface of the grasping flange opposes a surface of the attachment flange.
A recloseable zipper pouch comprising:
- (a) a surrounding wall having a closed bottom, first and second opposite sides, and first and second opposing wall panels between the first and second opposite sides, and an open mouth defined by terminal ends of the first and second opposing wall panels;
- the surrounding wall defining an interior volume therein;
- (b) a recloseable zipper closure between the terminal ends and the closed bottom;
- the zipper closure providing selective access to the interior volume through the mouth;
- the zipper closure including:
- an attachment flange having an inner surface and an outer surface;
- (ii) a first zipper profile member extending from the outer surface of the attachment flange and extending toward the second wall panel;
- the attachment flange being secured to the first wall panel along only an anchored portion of the inner surface and being free of attachment to the first wall panel at a region behind the first zipper profile member;
- (ii) a second zipper profile member secured to the second wall panel and extending toward the first wall panel and in a location to engage the first profile member;
- (iii) the first and second profile members being constructed and arranged to selectively interlock when pressed together and unlock when forced apart;
- and
- (c) an adjustable grasping flange integral with the attachment flange and being positionable between the attachment flange and the first wall panel;
- the grasping flange having a free end, a first surface, and an opposite second surface;
- (ii) the grasping flange being adjustable between a hidden position and a closure-opening position;
- (A) the hidden position including the free end being located between the attachment flange anchored portion and the first zipper profile member, and the first surface being adjacent the inner surface of the attachment flange;
- and
- (B) the closure-opening position including the first surface of the grasping flange pulled away from the inner surface of the attachment flange;
- wherein the grasping flange is freely movable and free of attachment to the first wall panel at the region behind the first zipper profile member for a complete distance between the first and second opposite sides of the surrounding wall;
- and
- wherein when the package is in a closed condition with the first and second profile members interlocked, the first surface of the grasping flange opposes the inner surface of the attachment flange.
