The invention relates to a cap of the type that is cylindrical in shape and includes splines and removable strips. The invention is characterised in that it is formed by a cylinder, a closed end, and, at the opposite end, an open end. The external part of the cylinder includes at least two parallelogram-shaped splines (preferably fifty-four) arranged equidistantly along the entire periphery of the cylinder. The splines extend from the open end of the cylinder to the closed end thereof and the last third of the spline-forming parallelogram nearest the closed end is tapered towards said end. The splines facilitate the handling of the cap in the machine used to produce same and the removal of the removable strip. The invention relates to a circular cap having 54 external splines that are tapered in the upper portion thereof. In order to establish a leak-tight seal and to preserve the contents of the container, the interior of the cap is provided with a thread having two full turns, removal being enabled with a rotation force or torque. The cap can be used in a leak-tight and secure manner on liquid containers, owing to the security band that is supported in the mouth of the container. This is removed when the container is opened, without said band being left in the neck of the container. |
