  • Publication number: 20050109780
    Abstract: Drinking cup lids are especially adapted and configured to afford some measure of protection to the game piece from beverage seepage through a straw opening. Preferably, the cup lid is configured so that a game piece is spaced above the straw opening co-located within a recessed well of the lid thereby allowing beverage seepage to remain physically separated from the game piece. Access to the beverage within the cup is facilitated by providing a cross-cut straw aperture in the game piece which is in substantial alignment to the straw opening formed in the lid. A beveled segment of a raised plateau on which the game piece is affixed allows a tab associated with the game piece to be more easily grasped and removed by a customer to reveal the printed text/indicia of the game piece.

  • Patent number: 6852071
    Abstract: 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.

  • Patent number: 6173858
    Abstract: 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.

  • Patent number: 6126585
    Abstract: 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.

  • Patent number: 5799814
    Abstract: A container lid includes a flap region that is selectively displaceable between a static raised position and a static depressed position. A flap is cut out of the flap region and is substantially integral with the flap region when the flap region is in the static raised position. When the flap region is displaced to the static depressed position, the flap separates from the flap region enabling liquid to flow therethrough. When the flap region is returned to the static raised position, the flap is again substantially integral with the flap region to thereby close the lid and prevent liquid from escaping. A knob is provided preferably integral with the flap region to facilitate displacement of the flap region.
