Abstract
The device comprises a rigid container, a manual pump mounted on the container for dispensing in unit doses the product contained in the container and a filter for filtering outside air entering the container when the pump is actuated. The pump has no air intake in the container and the filter is arranged in an air intake passage provided in the base of the container, which is injection-moulded. The invention is useful for packaging and dispensing of fluids, in particular liquids, which need to be maintained germ-free.
