<p>The invention relates to a discharge pump (10) for discharging liquids, gels or the like from a container. The invention especially relates to a bag (28) that can be placed in an outer container (30), is welded to the distributor pump and consists of a flexible foil material. The distributor pump (10) comprises a pump body (14) that can be fixed to the edge of a lid opening (34) in a fluid tight manner, whereby said opening is configured in a container lid (32). The inventive pump also comprises a small distributor tube (12) which is mounted in the pump body (14) in an axially displaceable manner and can be moved from a closed position against the effect of an elastic element, especially a screw compression spring (18). The inventive pump also comprises a ring seal (22) which is arranged between the edge of the lid opening (34) and/or the pump body (14) on the one hand and the small distributor tube (12) on the other hand. The ring seal consists of rubber or another elastic sealing material of the same kind and closes an access to a distribution channel (20) when the small distributor tube (12) or the distributor pump (10) is in the closed position. Said channel is configured in the small distributor tube (12). A locking pin (16) is axially mounted in the distribution channel (20) in the small distributor tube (12) in such a way that said pin releases a fluid-filling link extending through the distribution channel (20) to the container (28) for filling the container (28). After filling of the container (28), said pin can be moved into a position wherein the aforementioned fluid-filling link is closed.</p> |
