ABSTRACT:
A device for evacuating air from a container comprises a closing cover, to sealingly close an opening of a container, having an opening closable by a valve. The closing cover further has at its upper surface an annular flange surrounding the opening therein. The device also comprises a separable evacuating pump having a cylinder which may be sealingly connected to the closing cover by pressing the cylinder over the flange until the end surface of the cylinder engages the part of the closing cover from which the annular flange projects, in order to achieve a sealing action in two planes substantially perpendicular to each other, and also locking the pump against lateral displacement relative to the closing cover.
