A push tab container assembly includes a container and a lid configured to mate with the container in an unlocked state and in a locked state. The container includes a push tab assembly having a locking member defining a ramped surface and ending at a locking edge. The locking edge is vertically oriented with respect to the ramped surface and is tapered as it extends radially inwardly. The container has exactly one external container thread positioned on an external surface and at least one internal thread positioned on an internal surface. The lid has at least one locking lug positioned on an internal surface of a second skirt. The locking lug has a lug edge that tapers as it extends radially inwardly. When the lid is operably oriented relative to the container in the unlocked state, the external lid thread is mated with the internal container thread. When the lid is operably oriented relative to the container in the locked state, the internal lid thread is mated with the exactly one external container thread, while the locking edge of the locking member is engaged against the lug edge of the locking lug. The push tab assembly is actuatable to release the locking edge of the locking member from the lug edge of the locking lug to permit disengagement of the lid from the container.

A push tab container comprising: (a) a container having an open end, an external surface, an internal surface; exactly one external container thread positioned on the external surface; exactly one internal container thread positioned on the internal surface; and a push tab assembly mounted on the external surface, the push tab assembly including: (i) an engagement member having a top surface facing the open end, and a contact edge defining a free end of the engagement member; (A) the contact edge being spaced radially outwardly from the external surface of the container;(ii) at least one connecting arm adapted to mount the engagement member to the external surface of the container; and(iii) a locking member extending from the top surface of the engagement member in a direction toward the open end of the container; the locking member defining a ramped surface facing the open end; the ramped surface ending at a locking edge; (A) the locking edge being vertically oriented with respect to the ramped surface; and(B) the locking edge being tapered as it extends radially inwardly. 2. The push tab container of claim 1 wherein the locking edge is tapered at an angle of 10-30 degrees. 3. The push tab container of claim 1 wherein the contact edge is beveled in a direction downwardly and outwardly about 40-50 degrees from a direction of the open end of the container. 4. A lid configured to mate with a push tab container; the lid comprising: (a) a first skirt; (i) the first skirt having at least one external lid thread positioned on an external surface of the first skirt;(b) a second skirt; (i) the second skirt having exactly two internal lid threads and at least one locking lug positioned on the internal surface of the second skirt; (A) the locking lug including a lug edge projecting radially from the second skirt;(B) the lug edge being tapered as it extends radially inwardly;(ii) the second skirt having an external surface with a perimeter shaped as a regular polygon having at least 6 sides. 5. The lid of claim 4 wherein second skirt external surface has at least 10 sides, and each of the sides of the second skirt external surface is serrated.
