"AUTOMATIC CLOSURE, OR CORK, PERFECTED" which is characterized by being essentially constituted by two pieces of semi-flexible material, complementary, flat base whose male piece has a cylinder in its center whose upper base is widened into a disc determining a peripheral protrusion and the female part also has in its central part a quadrangular opening of sides with rounded section, having faced with each of the sides elongated holes that determine the flexibility of the resulting spars between the two openings, to yield to the pressure that produce the projections of the male piece when the passage of this is forced through the opening of the female for the purpose of joining both pieces.
