ABSTRACT:
The invention provides a protective or safety closure which inhibits inadvertent opening of the container. The neck portion of the container itself is provided with threads along which a notched portion, for example, in the form of serrations, is provided. The interior of the cap itself is also provided with threads which cooperatively engage the threads in the neck portion. Along the threads in the cap a notched portion, such as in the form of serrations, is provided to engage the serrations of the neck portion to lock the cap in position. Resilient members are also provided on the underside of the cap portion to engage the top of the neck portion which perform the function of bringing the notched portion in the cap into engagement with the notched portion on the neck of the container. In order to disengage the parts it is merely necessary to manually depress the cap portion against the action of the resilient members such as springs whereby the serrations are displaced out of engagement and the cap may be turned to open the container.
