Patent ID: 7201296

Claim:
A dosing device comprising: a pumping device; and an operating handle associated with the pumping device, wherein the operating handle is manufactured as a separate component from the pumping device and is fixed to the pumping device by a locking connection, and wherein the pumping device comprises: a radially extending surface configured to axially engage the operating handle so that a manual operating force applied to the operating handle is transferred from the operating handle to the pumping device; and a retaining mechanism on the pumping device configured to axially engage the operating handle and, in cooperation with the radially extending surface, fix the operating handle to the pumping device, the retaining mechanism being a locking groove sized to receive a part of the operating handle therein to facilitate the locking connection, whereby the locking connection of the operating handle to the pumping device assembles the dosing device into an operational configuration, and wherein a protective cap surrounding at least one discharge opening of the pumping device is detachably fixed to the pumping device, the protective cap being substantially matched to the shape of the operating handle such that the operating handle is engageable on the pumping device even when the protective cap is fixed to the pumping device.
