Abstract
A liquid applicator including a valve body for insertion into the neck of a liquid container, a duct in the valve body, a resilient web formed integrally with the valve body and extending transversely across the duct, a valve seat on one end of the valve body, a valve member secured to the resilient web and having a valve biased into engagement with the valve seat at the end of the valve body, a coating member mounted on the opposite end of the valve body, and a valve stem on the valve member located proximate the coating member for being deflected when the coating member is compressed onto an external surface to thereby unseat the valve and permit liquid to flow through the duct onto the coating member.
