Abstract
An apparatus for dispensing liquid with a specialized refill including a flexible reservoir and mesh screen is disclosed. The apparatus includes a housing; a flexible reservoir for storing the liquid; disposed within the housing; a flexible tubular member connected to the reservoir for selectively dispensing the liquid from the reservoir; and, a flexible mesh screen disposed within said reservoir. The flexible mesh screen produces a plurality of flow channels between the reservoir material and the output orifice of the reservoir to enable said liquid to continuously empty into said tubular member. In a preferred embodiment, the screen is a square screen with a side dimension at least equal to the diameter of the output orifice at the bottom of the reservoir and is fabricated from a plastic coated fiberglass material.
