Bottle cap with inserted seal. In the inside surface of the bottom 5 of the cap 1 there is provided an annular peripheral indentation 7 in which the upper edge 9 of the bottle 10 pushes and clamps the outer annular edge of the seal 11, efficiently preventing its intake of air under the effect of the depression created inside the bottle when a hot liquid has been put into it before tightening the cap. <IMAGE>
