Abstract:
1. A container cap, comprising: a movable cover, comprising a top panel having a bottom extended with an insertion tube, wherein the insertion tube is formed with slits and has a bottom formed with a flange and two corresponding protuberances, and the insertion tube further has a front side formed with an opening, in which the top panel has an outer periphery protrudingly formed with a marker projection in vertical alignment with one said protuberance at the bottom of the insertion tube, and the top panel further has a bottom centrally formed with an annular, toothed surface and an annular projection; an outer annular housing, having a through hole and an inner annular surface concavely formed with two corresponding, vertical grooves, each said groove having an end transversely extended with an insertion slot, wherein the outer annular housing has an inner annular surface comprising a bottom portion formed with an annular recess, and the outer annular housing further has an outer periphery comprising an upper portion protrudingly formed with a marker projection corresponding in position to one said groove; an inner cover, having a top formed with an annular, toothed surface having an inner periphery provided with an annular notch, the inner cover further having a through hole; and an annular plate, to be fixedly installed at a bottom of the outer annular housing; wherein the container cap is assembled by: inserting the insertion tube of the movable cover into the through hole of the outer annular housing, with the slits formed on the insertion tube providing contraction spaces to facilitate the insertion of the insertion tube in place, so that the flange and the two protuberances at the bottom of insertion tube are engaged in the annular recess on the bottom portion of the inner annular surface of the outer annular housing, thereby preventing the movable cover from disengagement and allowing only axial rotation of the movable cove; placing the inner cover so that the annular, toothed surface and the annular notch of the inner cover are engaged with the annular, toothed surface and the annular projection at the bottom of the top panel of the movable cover, respectively; and installing the annular plate fixedly at the bottom of the outer annular housing to complete the container cap, which serves to sealingly close an opening of a container.
