  • Combination caulking tube cap and applicator device
    Patent number: 5301843
    Abstract: A combination cap and applicator device is disclosed for capping a container of air curable material and for spreading the material dispensed from the container. The device includes a cap having a cylindrical inner sleeve for engaging a nozzle of the container to thereby form an interference friction fit for sealing the nozzle. In addition, the spreader blade includes a pair of laterally extending wing portions for defining a concave spreader surface. The spreader surface decreases in width in a direction extending away from the cap body to form a thin flexible edge which deflects to provide a wiping action as the spreader blade is used to form a bead of caulking material.
