Abstract
A fine-line applicator device creates an air-tight seal on a container of a substance, while preventing clogging in an applicator tip. The device includes a first cap, a nozzle protruding from the cap, a second cap engaging the nozzle, a hollow-bore needle protruding from the second cap, an end cap engaging the second cap, and an elongated member protruding from the end cap, such that the elongated member can be inserted into the hollow-bore needle. When the device is in a closed position, the elongated member occupies the interior chamber of the hollow-bore needle while the end cap engages the second cap to form a substantially air-tight seal, and when the end cap is removed from the second cap, the elongated member vacates the interior chamber of the hollow-bore needle to allow flow of a substance from the container through the needle.
