Abstract (en)
The invention herein relates to pumps and valving arrangements for fluid dispensers. The pumps herein comprise a dose chamber, a resilient actuator, valves for controlling the flow of fluid into and out of the dose chamber and the upper and lower pump halves each formed from unitary mouldings, at least the upper pump half comprising a semirigid, thermoplastic material. The pumps are easily made via injection moulding from a small number of parts. Combination of the pump with a fluid reservoir provides a fluid dispenser which may further comprise an atomiser for forming a spray as fluid is ejected from a dispenser outlet. Methods of making the pump and valving arrangements are also provided by the invention. <IMAGE>
