A liquid dispenser (1) is provided, which is particularly useful for dispensing liquid medical compositions such as nasal sprays, although not exclusively. The sprayer uses at least one, but preferably two semi-rigid casing halves (2, 3) defining a liquid tank (12), in which a dip tube, a dosing metering pump and an outlet A bridging member (21) serving as an orifice is attached. An air inlet (8) that allows the inflow of air as it exits may be provided in the tank, in which case a liquid-impermeable and preferably a bacteria-impermeable cover (9) is provided. May be. Other structures have also been described that do not require such a cover or that can completely eliminate the need for an air inlet. |
