ABSTRACT:
Fill seal structures having an elastomeric seal element contained in a housing for use with a liquid filling machine for bottles having fill necks, wherein lifting mechanisms are employed to move the bottles upwardly toward sealing faces of fill ports on the fill bowl of the machine, and wherein the seal structures are designed to provide for fluid tight seals between the top open ends of the bottle necks and the sealing faces, wherein the seal element consists of a generally tubular wall providing a fluid flow passage having an outlet end section and a complex inlet end section, the outlet end section being formed to provide a first contact surface for engaging and sealing against the top open neck end of a bottle, the inlet end section having a generally radially inwardly directed flexible hinge segment integral with the wall at a hinge seam, an annular crest on a radially inner portion of the hinge segment and extending and facing generally axially outwardly therefrom, the crest being adapted to bear against the sealing face whereby the hinge segment and crest become rotated downwardly toward a more horizontal plane when the seal element is moved into its operating sealing position against the sealing face, whereby the crest and the first contact surface are adapted to hermetically seal the top open end of the fill neck against the sealing face during filling or the like of the bottle.
