Improved sealing cap, which is essentially characterized by being formed from a frusto-conical obturator, concentric to a cylindrical lateral surface, which is continued inferiorly below the greater base of the truncated cone, while superiorly it forms an annular plateau, to then originate a new externally ribbed cylindrical portion, which after a circular line of perforations are transformed into a skirt, which constitutes the seal, based on a frustoconical portion and finally another cylindrical portion, which on its internal face has annular ribs of wedge section and that in its outer face has a flap that facilitates, when pulling it, the tearing and corresponding detachment of the part that constitutes the seal.
