  • Patent number: 6488429
    Abstract: A liquid marker system utilizes three primary components to permit marking of lines of various widths from a single nib. The three components are a porous nib, a transfer wick and a squeezable container. Operation relies on different squeeze pressures applied to the housing to produce different line widths from the single nib as the nib is moved across a marked surface. The porous wick provides a resistance to flow until the bottle is squeezed and then supplies a minimum of capillary flow to the nib. The user squeezes the container to overcome the resistance of the wick. No venting of the container interior is required because the wick and nib system allows the passage of air into the container when the container is returned to its unstressed (i.e., un-squeezed) condition.

  • Patent number: 5904433
    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.
