  • Patent number: 8474689
    Abstract: A method for making a multilayered paper-containing product, for example a paper plate or tray, includes assembling two or more sheets of paper-containing material cut into blanks. The blanks are pressed together and shaped in a die, usually with a bonding agent being used to secure the blanks. Pleats are formed in the curved portion of the shaped product. However, the pleats on each blank are formed independently so that the folded region formed in the pleats are arranged in a staggered array and are not interleaved with the pleats of the other blank.

  • 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.

  • Patent number: 7513386
    Abstract: A container comprising a sidewall and an inner liner. The inner liner includes an intermediate portion affixed to the sidewall about a periphery of the intermediate portion. The sidewall includes a vent disposed within the periphery of the intermediate portion. The intermediate portion is adapted to separate from the sidewall such that ambient air flows through the vent to form an air pocket between the intermediate portion of the inner liner and the sidewall.

  • Patent number: 6919111
    Abstract: An improved paperboard has been bulk enhanced by retaining a substantial portion of bulk-enhanced additives including expandable microspheres in a suitable distribution within the paperboard. The cellulosic paperboard web has an overall fiber weight (w) of at least 40 lbs. per 3000 square feet and, at a fiber density of 3, 4.5, 6.5, 7, 8.3, and 9 pounds per 3000 square foot ream at a fiberboard thickness of 0.001 inches, has a GM Taber stiffness of at least about 0.00246 w2.63 grams-centimeter/fiber mat density1.63, and a GM tensile stiffness of at least about 615+13.18 w pounds per inch. The high retention of the bulk enhancing additives is believed to result from the incorporation of suitable retention aids. The resulting paperboard has better GM Taber stiffness values and GM tensile stiffness than prior art paperboards. The paperboard also has increased strain to failure and is able to be formed into suitable paperboard containers without loss of integrity.

  • Publication number: 20040209023
    Abstract: A method of making a texture-coated and/or insulation coated container from a flat paperboard blank in which a heat-hardenable liquid polymeric binder texturizing and/or insulating agent coating mixture is applied to one surface of the blank in a pattern of covered and open areas. This coating mixture is subjected to heat to cure the polymeric binder and expand the texturizing and/or insulating agent, optionally treated with moisture, and optionally heated to form the blank into the shape of a container, and the container produced by this method. The containers such as cups, plates, etc., are useful in food service. These containers have a coefficient of static friction which is about 0.2 to 2.0 and over and a kinetic coefficient of friction which is about 0.22 to 1.5.

  • Publication number: 20020041046
    Abstract: At least one container is disposed in contact with at least one mandrel to cause a thermoplastic polymeric film on the container to foam and become a heat insulative layer. The mandrel is heatable to a predetermined temperature and the container is in direct contact therewith or disposed thereon for a predetermined period of time, to thereby cause the foamable material on the container to foam. A method of making a web of heat insulative nonwoven material includes providing a web of nonwoven material, applying a layer of thermoplastic polymeric material to a first surface of the web to form a web laminate, placing the web laminate in contact with a heated surface, heating the web laminate and thereby expanding the layer of thermoplastic material with moisture that is vaporized from the nonwoven material. The web laminate may then be fabricated to form a container or a portion of a container.
