Patent ID: 7942280

Claim:
A push tab container assembly, comprising: (a) a container having an open end, an external surface, an internal surface; exactly one external container thread positioned on the external surface; at least 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; (b) a lid configured to mate with the container in an unlocked state and in a locked state, the lid including first and second peripheral skirts; (i) the first skirt having at least one external lid thread positioned on an external surface of the first skirt; (ii) the second skirt having at least one internal lid thread 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; (iii) when the lid is operably oriented relative to the container in the unlocked state the at least one external lid thread is mated with the at least one internal container thread; and (iv) when the lid is operably oriented relative to the container in the locked state: (A) the at least one internal lid thread is mated with the exactly one external container thread; (B) the locking edge of the locking member is engaged against the lug edge of the locking lug; and (C) the engagement member of 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.
