ABSTRACT:
An end cap is attached to a container body to form a liquid media package for dispensing liquid media. The end cap includes an aperture in fluid communication with the liquid media in the package. The end cap also includes at least one radial arm extending outwardly from the aperture, each radial arm being in fluid communication with the aperture. Each radial arm includes at least one flexible wiper in a closed position, and one orifice corresponding to each of the at least one flexible wipers. When pressure is exerted on the liquid media, the liquid media travels through the aperture and then through the radial arms. The pressure of the liquid media displaces the flexible wiper so as to enable flow of the liquid media through an orifice in the bottom of the end cap. The flexible wiper returns to the closed position when exertion of pressure ceases.
