Abstract

The invention provides a crushable pumping chamber, i.e., a blower to be used as a liquid dispensing pumping device. The crushable pumping chamber includes a crushable lateral wall defining an internal volumetric portion of the pumping chamber. The crushable lateral wall has a structure which is crushed in a predetermined pattern while the pumping device is actuated. For example, the crushing predetermined pattern could result in a relatively small volumetric change of the internal volume thereof per a given stroke length, followed by an increased volumetric change of the internal volume per a given stroke length. Thus, the pumping device will initially provide a very good control over the amount of product dispensed, thereby providing a precise control during partial actuation thereof. However, the pumping device itself could be able to provide a large volume of product during a complete actuation.
