Abstract: A portable applicator for uniformly applying insect repellent or sunscreen upon human skin. A jar-like container normally holds the liquid contents. The container is sealed by a circular lid. The lid supports a downwardly-projecting sponge wiper that is saturated with liquid for subsequent topical application. The underside of the lid has a glue area surrounded by a peripheral ring for securing the wiper, and channels for directing fluid.
