Abstract
A process is disclosed for making a closure having (i) a top portion, and (ii) a latch member that includes an actuator portion and a follower portion, the follower portion including a blocking structure. The process includes providing a mold assembly that defines a space therein which corresponds to the closure, the mold assembly including (i) a first mold portion that defines a first subspace which corresponds to the actuator portion, and (ii) a second mold portion that defines a second subspace which corresponds to the blocking structure. The process further includes advancing a material into the space so as to form the closure. The process also includes moving the second mold portion in relation to the first mold portion after the advancing step so as to remove the actuator portion from the first subspace. In addition, the process includes urging an internal wall of the first mold portion into contact with the actuator portion in response to movement of the second mold portion in relation to the first mold portion so as to cause the actuator portion to move in relation to the top portion. Additionally, the process includes moving the follower portion in relation to the second m…
