  • Patent number: 8925477
    Abstract: A traffic cone has an annular base and a hollow conical body. The annular base has an annular panel having multiple through holes, and multiple first feet protruding down from the annular panel. The conical body has a conical portion and a covering panel radially protruding from a bottom peripheral edge of the conical portion and wrapped on the annular panel. Moreover, even if the traffic cone is bumped or is run over by cars, the annular and the conical body do not separate from each other easily so the traffic cone has prolonged life for use.

  • Publication number: 20140069320
    Abstract: A traffic cone has a conical body and at least one reflective sleeve. The at least one reflective sleeve is mounted on and around a conical portion of the conical body. Multiple adhering portions and multiple non-adhering portions are alternately arranged on a laminating surface of the at least one reflective sleeve. The adhering portions are adhered to the conical portion of the conical body. Thus, even though the at least one reflective sleeve and the conical body are different materials and have different coefficients of thermal expansion, the non-adhering portions provide rooms for expansion of the conical portion and the at least one reflective sleeve. Therefore, the at least one reflective sleeve is capable of remaining smoothly and securely attached despite the traffic cone being exposed to significant variations in the temperature of the environment.
