Abstract

Perfeccionamientos en pistones utilizados para excluir aire de recipientes, del tipo destinado para insertarse en una forma tubular hueca, cuya forma tiene un extremo abierto y comprende por lo menos una parte de la superficie interna de un recipiente, caracterizados porque cada pistón presenta una parte delantera insertable en dicha forma una distancia predeterminada desde el extremo abierto sin formar un cierre hermético entre el pistón y la horma, teniendo el pistón medios destinados a proporcionar un cierre prácticamente hermético al aire con la forma tubular después de la inserción de la cara delantera en la distancia predeterminada, siendo el pistón ademas desplazable en la citada forma una distancia mayor que la distancia predeterminada virtualmente sin reducción en el volumen contenido, por lo que el pistón se puede emplear para excluir el aire de un recipiente de otro modo lleno.
