<p>A safety cap for hand-held dispensers comprising a tubular cap body having a top discharge opening, a captive closure cap adapted to fit over the opening of the cap body so as to seal the same, and cooperable yieldable retainer means on the cap body and cap tending to hold the latter firmly in a closed, sealing position on the cap body. The cap is held captive on the body by means of a flexible hinge web structure which enables the cap to be swung from a sealing position closing off the body to a discharge position removed from the opening thereof. An interference lug and a lifting tab are disposed respectively on the cap body and cap. The lug and tab normally overlie and register with each other when the cap has been swung about the web structure and forced down to its sealing position on the body. In such a position, the cap can be turnably shifted on the body within limits determined by the web structure. The cap body and cap have cooperable detent lugs which can by-pass one another when the cap is turned, to yieldably retain the cap in a position wherein its lifting tab is out of registration with the interference lug on the cap body, such that the user's finger can then be easily applied to the underside of the lifting tab for the purpose of removing the cap.</p> |
