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.

[ What is claimed is:] [1.] A hand-held dispenser for user-controlled delivery of a stored fluid onto a work surface, comprising:a container having a storage portion for containing a supply of stored fluid and an applicator portion, said container portion including a flexible wall portion selectively deformable by a user for delivering stored fluid from the dispenser;an applicator carried on the applicator portion for receiving stored fluid from the applicator portion for user-controlled delivery of fluid onto a work surface;an insert disposed in said container between the storage portion and the applicator portion and defining a passage between said insert and applicator portion for accommodating flow of stored fluid from the storage portion to the applicator portion through said passage;sealing means on one of said applicator portion and said insert and movable relative to the other of said applicator portion and said insert from a first position in which said sealing means closes said passage against flow of stored fluid through said passage and a second position in which said sealing means is disposed so that said passage is open for delivery of stored flow from the container portion to the applicator portion through said passage;said applicator portion being moveable relative to said insert to relatively move said sealing means between said first and second positions;a cap for detachably engaged positioning in a fully seated condition about said applicator portion and said applicator to sealingly enclose said applicator within said cap; andsaid applicator portion further comprising an operating tab for engagement with said cap and configured for moving said applicator portion relative to said insert to relatively move said sealing means from said second to said first position of the sealing means as said cap is advanced into said fully seated condition about said applicator portion and applicator to thereby close said passage and thereby prevent the flow of stored fluid from said container portion to said applicator portion when the cap is fully seated about said applicator portion and applicator, and for accommodating said relative movement of the sealing means from said first to said second position of the sealing means as said cap is detached from engagement about said applicator portion and applicator to open said passageway and permit the flow of stored fluid from said container portion to said applicator portion and onto said applicator for user-controlled delivery onto a work surface;a vapor-discharge passageway defined in and through said insert for release of vapors from said storage portion to said applicator portion; anda pressure-activated check valve in said container portion for closing said vapor-discharge passageway when said container portion wall portion is selectively deformed for delivery of stored fluid from the dispenser.
