Abstract (en)
[origin: US4784286A] The invention describes a closing device for the gas-tight closing of an ever-ready container consisting of two shells for respirators. The closing device is arranged on one shell part and has essentially trapezoidally designed tension bands on whose longer side of the trapezoid hook-shaped parts are arranged which engage in correspondingly defined counter parts on the other shell part. A tension lever with unequal legs holds the tension bands together under tension.
