ABSTRACT:
A liquid applicator provides for a self-sealing feature, which applicator comprises a housing, a valve member and a spring member. The housing has an aperture through its top wall and an annular sleeve projecting inwardly from an edge of the top wall in a surrounding relation with the aperture, the annular sleeve having an end portion. The valve member includes an actuating part that is slideably received by the annular sleeve and a sealing part that is shaped to form a releasable seal with the end portion of the annular sleeve. The valve and spring members are disposed in an axially displaceable relation such that the actuating part of the valve member is resiliently urged into the annular sleeve; that a part of the actuating part protrudes from the top wall of the housing; and that the sealing part of the valve member sealably engages with the end portion of the annular sleeve.
