Abstract
A closure for a glue bottle including a cap having a body and a tip, wherein the body is adapted to be attached to a bottle or container, and wherein the bottle or container is adapted to store water-based glue; and an insert disposed at least partially within the tip of the cap, wherein the insert further includes a one-way valve for dispensing glue from the bottle or container when pressure is applied to the exterior of the container and preventing backflow of the glue into the cap when the pressure is released; at least one hydrophobic material; 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.
