Abstract:
1. A dispenser comprising a container for a fluid, the container comprising a casing defining an interior for storage of the fluid and a closure member, and a plunger for displacing the closure member relative to the container, the closure member comprising a body, at least one resilient projection, an outlet port and a sealing portion, the at least one resilient projection sealing the casing in a storage condition, and the outlet port being disposed between the at least one resilient projection and the sealing portion, wherein the sealing portion and the at least one resilient projection are in sealing engagement with the casing, wherein the closure member including the sealing portion is displaceable relative to the casing wherein, in use, displacement of the closure member increases the pressure in the interior of the container and, upon an increase in the pressure of the interior of the container the at least one resilient projection is deflected to accommodate outflow of fluid between the casing and the at least one resilient projection through the outlet port.
