| abstract |
A dispenser for a liquid is provided which is particularly, though not exclusively, useful for dispensing liquid medical compositions such as nasal sprays. The dispenser employs at least one, though preferably two, semi-rigid casing halves, defining a liquid reservoir, within which is mounted a bridge member which performs the functions of dip tube, dose metering pump, and outlet orifice. An air inlet may be provided into the reservoir, to allow air to enter as liquid leaves, in which case it may be provided with a liquid-impermeable, and preferably bacteria-impermeable, cover. Other constructions are described in which no such cover need be provided, or in which the need for an air inlet can be avoided altogether. |
