Abstract

Mold for manufacturing, by blowing blanks made of plastic material, containers having a body and a bottom and a wall defining a cavity around a principal axis of the mold and a lateral surface. The wall has, in a lower part, an opening defining a passage for a mold bottom, an upper surface that confers at least in part the shape to the bottom of the container, with said opening having an upper edge. The mold, in any plane containing the axis of the wall: the ratio between a transverse dimension of the upper edge of the opening and a transverse dimension of a lower end of the lateral surface of the wall is greater than 0.95, and the tangent to the lateral surface of the wall, at the lower end thereof, forms with the axis of the wall an angle equal to or less than 30°.
