  • Liquid sequestration bag with pinch closure
    Patent number: 9539158
    Abstract: The bag has a closure mechanism that simplifies and reduces the cost of the bag as compared to bags with conventional one-way valves. In one embodiment the valve is formed by two bond lines extending across the width of a plastic bag at different heights and terminating with one bond line above the other to leave an opening through which the bag is filled. Hydrophilic material expands to tension the opening and pinch it closed. In a second embodiment the one-way valve is formed on the angled edges of a two layer insert. This embodiment is functional with or without hydrophilic material. In both embodiments a supplemental closure is secured at the top of the bag to simplify opening the bag top and holding the bag while in use.
