Abstract
A safety type cap for medicinal or similar containers capable of effecting a tight seal upon the container mouth by means of a sealing flange extending laterally from an inner surface of the cap rim which is deflected upon contact with a corresponding flange on an area surrounding the mouth of the container. The cap is held in sealed relation relative to the container by engagement of a pair of arcuate projections which engage a sufficient degree of the container periphery so as to resist dislodgement made possible by flexing of the container without alignment of the cap relative to the container for normal usual disengagement.
