Abstract
Procedimiento de moldeado de una botella de plástico con fondo conformado y botella así obtenida, comprendiendo un proceso inicial de soplado de una preforma de la botella en un molde con la forma del contorno circundante exterior, estando la preforma sometida a un caldeo o calefacción variable en su longitud a fin de obtener en la parte extrema de la botella correspondiente al fondo o base una pared de material de un grosor mayor que en el resto del cuerpo durante la operación de soplado. En un siguiente paso dicho fondo de la botella es sometido a estirado por un macho de movimiento axial que es introducido en el molde cuando la botella se encuentra aún en estado fluyente conformando un ahuecamiento del fondo de forma correspondiente a la cabeza del macho. La botella así obtenida presenta en su base o parte inferior un ahuecamiento o concavidad cuyas paredes son estructuralmente resistentes a considerables presiones internas, como por ejemplo contener bebidas carbónicas o con gas.
