PUMP ASSEMBLY FOR CONNECTION TO A CONTAINER

摘要

Disclosed is a pump assembly (100) for connection to a container (200) and comprising: a base (10) for connection to the container (200) and defining a first flow path; a dispenser (20) defining a second How path and an outlet in fluid communication with the second flow path; a deformable vessel (30) defining a cavity of variable volume fluidly connecting the first flow path to the second flow path; and a resilient device unitary (40, 50, 60) with one of the base (10) and the dispenser (20) and discrete from the vessel (30); wherein the dispenser (20) is movable relative to the base (10) to deform the vessel (30) thereby to vary the volume of the cavity, and the resilient device (40, 50, 60) is configured to urge the dispenser (20) away from the base (10) thereby to increase the volume of the cavity. Also disclosed is a dispenser apparatus comprising such a pump assembly, and a method of manufacturing such a pump assembly.
