ABSTRACT:
A container made of flexible material with an inherently stable base and a method for manufacturing the container, the container being obtained in the shape of a pouch which has, in the region that will form the base, heat-sealed lateral regions and optionally ribbed guides which, by virtue of the very weight of the material that is introduced or by way of a punch, produce a base which makes the final container inherently stable.
