Sachet-seal characterized essentially by a piece of paper or similar material in the shape of a truncated pyramid to be folded precisely in its central part where the limit of two forms presented by said piece is seen so that a sachet-seal is formed when attaching or to hold the four sides that form said cuts, thus leaving a flange on both sides thereof.
