  • Patent number: 7841974
    Abstract: The present invention provides a container (10) suitable for providing insulation wherein the container has an inner shrink film (14) liner. The sidewalls of the container, which can be made from paperboard or other suitable material, are vented to allow ambient air to freely flow through the sidewall of the container during activation of the shrink film (14) with hot liquid or other suitable material. When the container is filled with material having a temperature of from about 130° F. to up to about 212° F., the shrink film (14) is activated and the container (10) provides excellent insulation, thereby allowing the container to be held in a consumer's hand for an extended period without causing burns or excessive discomfort. Method of making this container (10) are also provided.

    Abstract: In a non-round container forming machine having a device for receiving and delivering flat container wall blanks to a wrapping station, at which the blanks are wrapped around a non-round mandrel. The non-round mandrel has a front end facing the blank. The blank is aligned substantially tangential to the mandrel when delivered to the wrapping station. A wing slide assembly, within the wrapping station, moves linearly along opposite sides of the mandrel in a wrapping direction substantially perpendicular to the blank to fold the blank along opposite sides of the mandrel. A forward wing clamp assembly, within the wrapping station, is mounted proximate a rear end of the mandrel to move pivotally to engage and direct outermost portions of opposite ends of the blank in an overlapping relation against the mandrel to form a side seam. The containers are removed from the mandrel with an extractor plate which physically engages the containers upper edge.

  • Patent number: 4505423
    Abstract: A liquid-tight paperboard container having at least one radiused corner is disclosed, together with a method for manufacturing it. The container includes a sidewall member having a bottom edge portion folded under a bottom piece to define a flange which is sealed to the bottom piece by means of heat and pressure. The region of the seal between the flange and the bottom piece is defined by a knurled surface on the flange. This permits the formation of a high quality, reliably liquid-tight container using relatively low pressures. In addition, the portions of the bottom edge of the sidewall member adjacent the radiused corners of the container are preferably provided with slits or notches to limit the buckling that occurs during the process of folding the edge under the bottom piece. By doing this, in combination with the use of a knurled for sealing, containers having corners with unusually small radii of curvature be reliably, easily and inexpensively manufactured.

    Abstract: A container having a generally rectangular rim surrounding its opening is closed by a foil membrane that extends over the rim and is sealed to the rim by inductively heating it. The membrane does not correspond in configuration to the rim, but instead its side and end margins curve away from the sides and ends, respectively, of the container rim, so that the peripheral margin of the membrane is located closer to the container rim at the corners of the rim than at the sides or ends of the rim. The foil of the membrane is coated with a resin bonding material, and when the membrane is placed in a rapidly oscillating magnetic field, its foil is inductively heated throughout the entire area that overlies the rim, thereby rendering the bonding material plastic and establishing a uniform bond between the rim and membrane.
