摘要：
A closure for a container including an indicator mechanism to record the removal of the closure from the container and a child-resistant mechanism to resist the removal of the closure from the container by a child. A spring in the indicator mechanism urges the indicator mechanism toward the child-resistant mechanism to provide sufficient force to engage the child-resistant mechanism for the attachment of the closure to the container, but not sufficient force to engage the child-resistant mechanism for the removal of the closure from the container, so that an additional external force must be applied to engage the child-resistant mechanism for the removal of the closure from the cap. The additional, external force is also necessary to engage the indicator mechanism, so that the mechanism cannot be inadvertently advanced.
