An improved cap closure that being the plastic material, essentially is characterized in that it is constituted from a tubular portion of constant circular section that by one of its mouthpieces receives the adjustment of a frustoconical body of lower height expanded inferiorly in a fin annular, against which internal body is adapted by heat shrinkage of the tubular portion, which at its upper part is refuted, forming, by pressure contribution, a wall of greater thickness than that which has the lateral surface, having provided that the original tubular portion lack of seam and with the particularity that on the outer face of the base that is shaped and that has greater thickness than the rest is in relief a sign caused as against the footprint of the heating plate that presses the tubular portion to shape the wall thicker.
