Claim Text:
1. A closure for a container comprising: a cap comprising a base portion adapted to be attached to a container that is adapted to store water-based glue, an upper closure portion defining an aperture at a topmost section thereof and defining a substantially conical fluid passage for dispensing glue from the container, the substantially conical fluid passage extending between the aperture and the base portion of the cap; and an insert disposed at least partially within the aperture of the upper closure portion of the cap, wherein the insert is formed of at least one hydrophobic material and comprises (i) a self-sealing one-way valve for dispensing glue from the container when pressure is applied to the exterior of the container and for preventing backflow of the glue into the cap when the pressure is released, and (ii) a substantially conical sleeve portion disposed in the fluid passage of the cap, wherein the at least one hydrophobic material is operative to encourage the water-based glue to flow back into the container after the pressure has been released and when the container is stored in a vertical position.
