  • Patent number: 4280864
    Abstract: A device and method for applying a semi-liquid adhesive material in a preselected pattern upon a surface such as the inner surface of a container cap such that a liner may be adhesively connected thereto. The device and its manner of operation are particularly suited for the application of hot melt adhesive to container caps of the type having a central recess surrounded by an annular ledge. A member having a longitudinal bore in which a shaft having one or more external helical grooves is rotationally disposed, cooperates to form the applicating device. One end of the member is operationally associated with a supply of semi-liquid adhesive such that rotation of the shaft with respect to the member will force adhesive along the separate helical paths and on to the receiving surface of the cap in the desired configuration.
