ABSTRACT:
A cap locking member for locking a cap in a closed position relative to the neck or spout of the can or container to prevent removal or unscrewing of the cap by a child and providing a safety factor whereby only an adult can unscrew the cap by using both hands. The said cap locking member is secured to the top of the can or container and has an upwardly extending portion which has a notch or recess with the transversely extending front edge thereof engaging the underside of the cap whereby the front edge is imbedded into the underside of the cap in such a manner as to prevent counterrotation or unscrewing of the cap unless the container is held with one hand and with one of the fingers of that hand applying sufficient manual pressure to depress the manually engageable portion of the locking means to effect disengagement with the cap while simultaneously rotating the cap in a counterclockwise direction with the other hand to unscrew same. The cap locking member is formed essentially of a spring metal which is integrally formed and inexpensive to produce.
