A thermoplastic squeeze tube has a self-sealing orifice where a one-way valve member is secured in the tube neck and an exposed portion thereof enclosed and protected by a frangible closure member integral with the neck portion. A pocket in the bottom wall of the frangible closure member closely encloses the one-way valve member to seal the same. A replacement cup-shaped closure member may be provided to reseal the tube after removal of the frangible closure member, which may have downwardly depending sealing protrusions which contain the upper portion of the exposed section of the one-way valve member to reseal the same.
