Resealable storage bag and associated components

Abstract

A resealable storage bag features a dual-rib zipper profile in which two bulb-tipped male ribs on one wall lock into matching rounded grooves on the opposite wall, creating a robust airtight seal. An exterior slider with ergonomic pinch zones and a stepped, multi-slot channel guides the ribs into the grooves, allowing the seal to be achieved in a single pass even when the closure elements use softer resin blends. A hinged flap anchored to one wall carries at least part of the zipper profile and pivots between parallel and perpendicular positions. When the bag is stressed from below, the flap rotates to an orthogonal attitude that resists separation yet remains easy to open from above. A one-way valve enables vacuum evacuation for compact storage, while optimized divider lengths, ramp radii and slot clearances within the slider further enhance sealing reliability.
