摘要:
The dispensing closure is provided having a stopping mechanism that limits the rotation of the closure and generally prevents removal of the closure from the container. The dispensing closure includes a cap body, fitment, and container finish. The cap body has a double shell design, which includes at least one drop lug reverse tapered from the inner shell. When the cap body is rotated about the container finish, the reverse tapered drop lug engages at least one lug stop located on the container finish so as to limit the rotation, thereby preventing removal of the cap body from the container finish. The reverse taper of the drop lug maximizes the abutment surface and stability of the drop lug when engaging the corresponding lug stop.
