Abstract: A pen shaped device includes a brush-type applicating tip for dispensing and applying liquid that is stored in an integral fountain reservoir bag. The brush is permanently mounted outside the reservoir, receiving liquid through a hollow tube or other narrow passage. A check valve is provided within the device to prevent leakage during storage but the valve allows liquid to pass from the reservoir to the brush under the impetus of semi-automatic or manual finger-operable feed control. The brush is kept moist during storage by being capped in an air-tight enclosure which receives vapor of the liquid through a vapor-permeable membrane communicating with the reservoir.
