ABSTRACT:
The inventive fluid dispenser includes a container in which the fluid to be dispensed is stored and an attached brush-type applicator from which the stored fluid may be selectively applied to a work surface. The container has an open end to which an applicator housing is attached and which carries a bristled brush. An insert disposed within the applicator housing defines passageways through which stored fluid is deliverable from the container to the applicator housing. The fluid-delivery passageways are automatically closed when an associated cap is detachably positioned about the brush-carrying end of the dispenser through deformation or displacement of the applicator housing to prevent the unintended delivery of stored fluid into the applicator housing during periods of nonuse. The insert may also include a vapors-release passageway extending between the container and the applicator housing for venting vapors into the brush-enveloped cap and thereby prevent drying out of the brush during periods of nonuse. The vapors-release passageway is closeable by a check valve against the unintended flow of stored fluid therethrough.
