Abstract
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.
Claims7
A closing device with tension bands for the gas-tight closing of an ever-ready container comprised of an upper shell and a lower shell of approximately equal size for respirators, where the tension bands are pulled together and held by a toggle catch, wherein the improvement comprises:
- (a) the tension bands are arranged on the upper shell and are designed trapezoidally with the longer side of each trapezoid having hook-shaped parts which engage into correspondingly defined counter parts arranged at corner points of the lower shell;
- (b) a locking element for the tension bands disposed between the shorter sides of each trapezoid;
- and
- (c) a tension lever having a shorter and longer lever leg, said tension lever extending from the locking element with the end of the longer lever leg surrounding adjacent edge portions of the upper and lower shell.
A closing device with tension bands for the tight closing of an ever-ready container comprised of an upper shell and a lower shell of approximately equal size for respirators, where the tension bands are pulled together and held by a toggle catch, wherein the improvement comprises:
- (a) the tension bands are arranged on the upper shell and the free ends thereof have hook parts which trapezoidally extend beyond the width of the tension bands and form a longer side of a trapezoid with the free ends;
- (b) a locking element for the tension bands disposed between the shorter sides of each trapezoid;
- and
- (c) a tension lever having a shorter and longer lever leg, said tension lever extending from the locking element with the end of the longer lever leg surrounding adjacent edge portions of the upper and lower shell.
