Abstract:
1. A zipper bag with a zipper opened and closed by a slider, including: first and second walls, joined together at a first side, a second side and a bottom, thereby forming a mouth; the mouth being reclosable by a zipper, the zipper including: a first profile with a first upper interlocking element, a first lower interlocking element, a first upper flange, and a first lower flange; a second profile with a second upper interlocking element, a second lower interlocking element, a second upper flange and a second lower flange, wherein the second lower flange is folded back on itself adjacent to the second upper interlocking element; the first and second upper flanges being continuous; the first profile and the second profile being joined together at an opening end seal and a closing end seal; a slider having an opening end and a closing end, a first side and a second side, a bottom including inwardly facing ribs to maintain the slider on the first and second zipper profiles, and a top having a wedge positioned to engage the first and second upper flanges; wherein when the slider is moved in a direction to open the zipper, the wedge forces apart the first and second upper flanges, thereby fully separating the first upper interlocking element from the second upper interlocking element and separating the first lower interlocking element from the second lower interlocking element up to a length of the slider when the slider is adjacent to the opening end seal, and when the slider is moved in a direction to close the zipper, the slider presses the first upper interlocking element to the second upper interlocking element and the first lower interlocking element to the second lower interlocking element along a full length of the zipper up to a length of the slider, when the slider is adjacent to the closing end seal; the first and second lower flanges extending beyond the inwardly facing ribs and being attached to the respective first and second walls; and wherein when the slider is adjacent to the closing end seal, the pressure of the inward facing ribs acting on the first lower flange and the second lower flange folded upon itself maintains the first and second lower interlocking elements interlocked with each other up to the length of the slider when the slider is adjacent to the closing end seal, and the wedge maintains the first and second upper interlocking elements separated from each other.
