Abstract
A pump and pump securing device, which pump securing device includes, at its axially-outer end, an axially-outer step and a axially-inner step. These steps are used to interact with a radially-projecting flange on the pump, thereby allowing the pump to be securely snapped into the mounting cup without the need for crimping. The steps also control the position of the pump relative to the mounting cup. As a result, the steps prevent the pump from compressing gaskets in the assembly, thereby controlling variations in pump dosage resulting from gasket compression. The flange can include slots creating vent paths for venting air into the container during operation of the pump.
