Abstract
Flexible plastic bags having a closure capable of withstanding external force applied to the bag. The bag has a top opening which may be easily opened and closed by a closure member secured to the exterior of the bag forming a pocket having an opening. The pocket opening extends across a portion of the bag substantially parallel to and spaced from the open end. The open end may be folded over upon itself at least two times or twisted upon itself at least three times and the pocket turned inside out over the end portion to form a closure which is resistant to external forces. The bag of this invention is especially suitable for retaining liquids and gases when an external pressure is applied to the bag.
