Claims20
An apparatus for piercing and sealing a web of film to a fitment having a flange comprising:
- an abutment member including a heated face having a generally flat lower portion and a generally flat raised portion, both the generally flat lower portion and the generally flat raised portion adapted to contact the web of film during sealing, the generally flat raised portion sized to contact the web against a portion of the flange adjacent the fitment;
- and
- a heat seal tip extending from the raised portion of the heated face.
A heat sealer for piercing and sealing a web of film to a fitment having a flange comprising:
- an abutment member including a heated face having a generally flat lower portion and a generally flat raised area, both the generally flat lower portion and the generally flat raised portion adapted to contact the web of film during sealing, the generally flat raised area sized to correspond to a portion of the flange which contacts a portion of the web which is contacted only by the heated face during sealing;
- and
- a heat seal tip extending from the raised area and corresponding to the fitment.
A heat sealer for piercing and sealing a web of film to a fitment having a flange comprising:
- an abutment member including a heated face having a generally flat lower portion and a generally flat raised area, the raised area being sized to correspond to a portion of the flange which contacts a portion of the web which is contacted only by the heated face during sealing, the abutment member further including means for aiding in the removal of the heat sealer from a heating means;
- a heat seal tip extending from the raised area and corresponding to the fitment;
- and
- means for attaching the heat sealer to the heating means.
A heat sealer for piercing and sealing a web of film to a fitment comprising:
- means for attaching the heat sealer to heating means:
- an abutment member including a heated face having a raised area, and having flats circumscribing a portion of an outer circumference of the abutment member for aiding in the removal of the heat sealer from the heating means;
- and
- a heat seal tip extending from the heated face.
An apparatus for sealing a web of film to a fitment having a base comprising:
- a fitment press head located on a first side of the web of film for urging the fitment towards the web of film, the fitment press head having a backup member for backing up a portion of the base of the fitment;
- and
- a heat sealer for piercing and sealing the web of film to the fitment, the heat sealer located on a second side of the web of film and having an abutment member including a heated face and a raised area having a circumference substantially equal to a circumference of a portion of the base not backed up by the backup member, the heated face having a heat seal tip extending therefrom.
