  • Patent number: 7624697
    Abstract: An improved traffic cone (FIG. 1) in which the base's front of the traffic cone (3) has a semicircle shape (4, 5, 6), that prevents liquid spillage from spreading from one are to another. The center of the semicircle base will vary in height and width depending on the size of the conical body. The larger the cone, the larger the base, width and height of the semicircle thus allowing the traffic cone's base to contain and prevent liquid spillage from spreading beyond the semicircle area by containing, holding and preventing the spreading of water or other liquid material.
