发明名称 Child-resistant closure and container
摘要 A child-resistant closure and container system is provided with a snap on and off closure requiring a coin or tool to remove the closure. A skirt wall on the closure is positioned sufficiently close to a shoulder on the container that the gap between the bottom edge of the skirt wall and adjacent shoulder is insufficient to admit a tool or to allow the teeth of a child to enter and to be used to pry off the closure. The shoulder diameter is equal to or greater than the diameter of the skirt wall to prevent the child's teeth from engaging and prying off the cap. A small notch is formed in the skirt wall to allow a coin or tool to be inserted and to be twisted against the shoulder to pry off the closure.
