Abstract: A mold for traffic cones has a female mold, a male mold and two cavities. Because each first annular recess of the female mold and a corresponding second annular recess of the male mold can hold a base of the traffic cone steadily, the female mold does not have to be placed under the male mold. Then the sprue can be formed through the female mold and can be nearby the two cavities. Besides, the distributing recess of the male mold communicates with the sprue and the second annular recesses. As a result, a liquid plastic material injected from the sprue is distributed and flows into the two cavities. After the male and the female molds are separated, two traffic cones are completed. Therefore, the mold for traffic cones as described can make two traffic cones at a time, which raises manufacture efficiency.

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. Even if the traffic cone is bumped or is run over by cars, the annular base and the conical body do not separate from each other easily so the traffic cone has prolonged life for use.

Abstract: A pair of detachable eyeglasses has a frame, a bridge and two integral lenses. The frame has a skeleton and two side bars formed at two ends of the skeleton. A lug is formed in a middle portion of the frame and multiple joint members are symmetrically provided in rear sides of the side bars. The bridge has two nose pads and a fastener mounted between the nose pads. A channel is defined in the fastener and a block is received into the channel. A groove is defined in a middle portion of the lenses and mated with the block so that a lower end of the middle portion is received into the channel thereby fastening the lenses to the bridge. Multiple slots are defined in two edges of the lenses and mated with the joint members.
