摘要： Spirally-wound circular side walls may be re-formed into non-circular geometries which are then mechanically joined to conformably shaped non-circular closure disks and thereby produce non-circular two-piece paperboard container lids.
摘要翻译： 螺旋缠绕的圆形侧壁可以重新形成非圆形几何形状，然后机械地连接到顺应形状的非圆形封闭盘，从而产生非圆形的两件式纸板容器盖。

摘要： Single ply paperboard containers are wax-coated by directing a relatively narrow spray band of atomized wax towards the interior surfaces of the containers being treated. The spray band is volumetrically asymmetrical and is oriented relative to the interior surfaces of the container such that its volumetric asymmetry is directed towards the bottom circumferential seam between the tubular side wall and bottom wall of the containers. In this manner, a minimal (but fluid-impervious effective) nonsaturating amount of wax will be applied to the interior surfaces of the container so as to preserve the vivid appearance of color graphics and/or indicia that may be printed on the exterior surface of the container. At the same time, the volumetric asymmetry and orientation of the spray band ensures that a maximum amount of wax will be applied at or near the circumferential bottom seam so that a fluid-impervious fillet seal may be established thereat. The appearance of the color graphics and/or indicia may optionally be further improved by the electrostatic spray application of a suitable lacquer. The applied lacquer, when dried, will thereby enhance the "glossy" exterior appearance of the interior wax-coated containers.

摘要： Two-piece cups formed, e.g., from a thermoformable plastics material, include a bottom wall disc which is bonded to an inwardly turned annular bottom flange of the side wall by an upwardly and inwardly sloped transition wall. The transition wall allows the bottom wall disc to be bonded to the sidewall flange in such a manner that the annular bottom edge is substantially unaffected by the heat and pressures during the bonding process. The bottom wall disc may be in the form of multiple concentrically disposed, annular bottom wall segments which are connected to one another by respective ones of a plurality of transition walls.

摘要： In a cup sealing system including a cup former and at least one burner for sealing a cup bottom seam where a cup side wall blank is mated with a bottom disk, with one portion of the side wall extending beyond the bottom disk, an improvement wherein at least one burner includes a burner head with a plurality of circumferentially arranged flame nozzles and a pilot flame aperture, the pilot flame aperture adapted to be located axially adjacent the one portion of the cup side wall; a flame ignitor/sensor positioned adjacent the flame aperture; and a combustion chamber which extends from a forward edge of the burner at the flame nozzles to a location axially beyond the container side wall to thereby achieve uniform heating of the extended portion of the cup side wall. The burner head also includes a pair of relatively movable sleeves adapted to create an annular pilot flame ring gap on start-up.

摘要： Systems and methods for making a paperboard container include a sidewall blank heater assembly having upper and lower sidewall blank heaters for simultaneously heating upper and lower edge strips of the sidewall blank adjacent lateral edges thereof, and a bottom sidewall seam heater for heating a generally curved strip adjacent an arcuate bottom edge of the sidewall blank simultaneously with the upper and lower edge strips. The sidewall blank is thereafter curved about a forming mandrel at a container-forming station so as to overlap the heated upper and lower edge strips of the sidewall blank to form a longitudinal container side seam, while the bottom edge of the sidewall blank is brought into contact with a paperboard bottom wall blank to form an annular container bottom seam. A bottom seam heater assembly is most preferably provided for circumferentially heating the container bottom seam simultaneously while the sidewall blank is curved about the forming mandrel at the container-forming station. In such a manner, high quality, leak proof seams of the paperboard container ensue.

摘要： Apparatus for lubricating and curling a rim of a paperboard container includes a housing block defining a central recess sized and configured to accept therein a rim of a paperboard container to be curled. An annular curling channel is disposed in the recess for curling the rim of the paperboard container in response to relative advancing movement between the paperboard container and the housing block. The housing block also defines an annular liquid channel concentrically disposed in surrounding relationship to the annular curling channel for distributing lubricating liquid. A porous liquid transfer ring is attached to the housing block in covering relationship to the annular liquid channel so that lubricating liquid supplied to the liquid channel comes into contact with the liquid transfer ring. The liquid transfer ring includes a circular edge surface which defines a central opening such that the liquid transfer ring extends at least partially over the curling channel. In use, the rim of the paperboard container comes into wiping contact with the central opening of the liquid transfer ring so that lubricating liquid is transferred thereto prior to the rim being curled in the curling channel.
