  • Patent number: 4759755
    Abstract: An elongated sleeve member having an upper open end and a lower open end, and with an annular flange extending radially outwardly from adjacent the open lower end is affixed to an elongated stem member in a substantially vertical orientation for immersion in a liquid substance held in a vial. A sleeve-like surface extending between the open ends of the elongated sleeve member, and a surface defining the lower end of the sleeve and an outwardly extending annular flange provide means to remove a consistent quantity of a liquid substance, such as a liquid allergenic agent, from a storage vessel or vial, and to transfer the liquid to a receiving scarifier structure, such as a cluster of multiple scarifier points. The outer periphery and upper surface of the flange provide a means for carrying excess liquid, and the flange provides for wiping the excess liquid from the sleeve member and flange prior to dispensing a desired quantity of liquid allergenic agent onto a cluster of scarifier points.
