A substance dispenser for dispensing substance onto an article is provided with a substance reservoir for storing substance and an openable closure element. The openable closure element forms one wall of the reservoir while closing the reservoir and permits passage of the article therethrough and into the reservoir. The article is also withdrawn from the reservoir after substance is dispensed to the inserted article by way of the openable closure element. The openable closure element opens when the article is urged against the closure element and sealingly closes around the article as the article is inserted into the reservoir and withdrawn from the substance reservoir. The sealing closure around the article as the article is withdrawn is effective to wipe excess substance from the article and to retain the excess substance within the reservoir. The openable closure element may be a resilient diaphragm having a slit. The reservoir may be provided with a frustum directing device to urge the substance toward the slit as the substance is advanced. The substance may be advanced rotatably or may be biased toward the closure element by a compression spring. A further reservoir, in fluid communication with the substance storage reservoir and containing a desiccant, may be provided for removing moisture from the substance reservoir.
