Abstract
Closure construction for blow molded drums having an upstanding internally threaded neck. A closure plug with sealing gasket is screwed into the neck to provide a liquid tight seal. A plastic tamper evident overseal completely covers the plug and neck and is manually snapped in place so as to interlockingly engage the plug making both the plug wrench engaging structure and the overseal interlocking structure inaccessible without destruction of the overseal. A tear strip opening means is provided for authorized access.
