Abstract

Handpumpe zur Abgabe einer Flüssigkeit in einem Behälter, bestehend aus einem Pumpengehäuse (30) mit einem Pumpenzylinder (34), einer Befestigungsvorrichtung (40, 44) zur Befestigung des Pumpengehäuses (30) an dem Behälter, einem Saugrohr (78) am Pumpengehäuse (30), einem ersten Einwegventil (80) zwischen Saugrohr (78) und Pumpenzylinder (34), einem im Pumpenzylinder (34) verschiebbaren Kolben (120), einem Pumpenschaft (50) mit einem Durchgangskanal (54), einem Spenderkopf (60) und einer Vorspannfeder (90) für den Kolben (120), einem zweiten Einwegventil (140) zwischen dem Pumpenzylinder (34) und dem Durchgangskanal (54) des Pumpenschaftes (50), einer Hülse (70), die im Pumpenzylinder (34) angeordnet ist, einer Sperrvorrichtung (150) für den Pumpenschaft (50) in dessen Ruhestellung und Pumpenhub-Endstellung. Der Spenderkopf (60) ist mit einer Abdichtkappe (65) versehen, welche zur Bildung eines permanenten Überdeckungsbereichs (61) ein aus dem Pumpengehäuse (30) herausragendes Ende (73) der Hülse (70) in jeder Stellung des Pumpenschaftes (50) abdichtend verschiebbar übergreift. Dadurch sind die im Behälter enthaltene Flüssigkeit bzw. bereits in dem Pumpenzylinder vorhandenen Flüssigkeitsreste vor einer Kontaminierung oder anderweitigen Qualitätseinbuße geschützt.

Hand pump for dispensing a liquid in a container, comprising a pump housing (30) with a pump cylinder (34), a fastening device (40, 44) for fastening the pump housing (30) to the container, a suction pipe (78) on the pump housing (30 ), a first one-way valve (80) between the suction pipe (78) and the pump cylinder (34), a piston (120) displaceable in the pump cylinder (34), a pump shaft (50) with a through-channel (54), a dispenser head (60) and one Biasing spring (90) for the piston (120), a second one-way valve (140) between the pump cylinder (34) and the through-channel (54) of the pump shaft (50), a sleeve (70) which is arranged in the pump cylinder (34), a locking device (150) for the pump shaft (50) in its rest position and pump stroke end position. The dispenser head (60) is provided with a sealing cap (65) which, in order to form a permanent overlap area (61), can seal an end (73) of the sleeve (70) protruding from the pump housing (30) in any position of the pump shaft (50) spreads. As a result, the liquid contained in the container or liquid residues already present in the pump cylinder are protected against contamination or any other loss of quality.
