ABSTRACT OF THE DISCLOSURE A container provided with means for sealing and opening the interior thereof with positive locking action in either position, comprises a self-enclosed resilient side wall defining an inner region and having an undeformed stable configuration. The side wall has a first end and a second end with an opening at each end. An end wall is secured to the side wall member adjacent the second end so as to sealingly secure the second end opening. The container also comprises closure means integrally and movably secured to the side wall adjacent the first end opening. The closure means is configured and dimensioned so as to be bi-directionally selectively movable from a generally locked first position, wherein the closure means positively seals the first end opening, through an intermediate position to a generally locked second position wherein the closure means positively unseals the first end opening. In cooperation, the side wall resiliently deforms as the closure means moves between the first and second position through the intermediate position and thereby generates forces tending to return the side wall to its undeformed stable configuration. In this fashion, the return forces generated by the deformation of the side wall aid further movement of the closure means from the intermediate position to either the first or the second position. A frangible closure strip which renders the container tamper proof is also provided. A method for forming the container of the present invention is also disclosed.
