Patent attributes
A tamper evident cap assembly includes an outer cap having an outer cap end wall and an outer cap skirt, and an inner cap having an inner cap end wall and an inner cap skirt. The inner cap skirt has a thread on an inner surface for selectively fastening the cap assembly on a portion of a container. The thread has separations therein. The first and second vertical ratchet teeth of the outer cap and the inner cap, respectively, abut when the outer cap is turned in an application direction to rotate the inner cap and the outer cap together to fasten the inner cap onto the container. When a downward force is applied on the outer cap, the second end teeth on the inner cap engage with the first end teeth on the outer cap applying torque on the outer cap in the removal direction turning the inner cap to release the cap assembly from the container and rupture the tamper evident band.
