The tear strip is positioned between a portion of the label adhesive bonded to the base side wall and a portion of the label adhesively bonded to the lid skirt. The tear strip can be used to open the container.

  • Patent number: 8834980
    Abstract: A biocomposite material (1) and methods of production thereof are described. The biocomposite material (1) exhibits a physical stiffness, strength and toughness comparable to known glass fiber composites while its composition makes it inherently impermeable to water. A general formulation for the biocomposite material (1) is given by the expression: Cel(1-x-y) HPIx HPOy where “Cel” represents cellulose fragments (2), “HPI” represents hydrophilic binders (4), “HPO” represents hydrophobic binders (5) and (x) and (y) quantify the percentage by weight of the hydrophilic (4) and hydrophobic binders (5) present within a material, respectively. The described properties of the biocomposite material (1) are achieved when (x) is within the range of from 0.05 to 0.55 and (y) is within the range of from 0.05 to 0.65.

  • Patent number: 8834978
    Abstract: Spirally wound paper products are disclosed having desirable roll bulk, firmness and softness properties. The rolled products can be made from a multiple ply tissue webs formed according to various processes. Tissue webs having basis weights greater than about 40 grams per square meter were wound into rolls having a Kershaw roll firmness of less than about 9 mm and a roll bulk of greater than about 15 cc/g. Similarly, tissue webs having basis weights less than about 40 grams per square meter were wound into rolls having a Kershaw roll firmness of less than about 9 mm and a roll bulk of greater than about 18 cc/g.

  • Patent number: 8834677
    Abstract: The present invention provides tissue products having an MD/CD Tensile Ratio less than about 0.95, yet relatively high geometric tensile strength, such as geometric mean tensile strengths greater than about 1500 g/3? and more preferably greater than about 2000 g/3?. The combination of a tough, yet relatively supple sheet is preferably achieved by subjecting the embryonic web to a speed differential as it is passed from one fabric in the papermaking process to another, commonly referred to as rush transfer.

  • Publication number: 20140255630
    Abstract: The objective of the present invention is to provide a molded paper body in which the outer peripheral portion of a blank primarily of paper is formed in a raised shape using draw processing, wherein the molded paper body eliminates the occurrence of wrinkles causing leaking or instability of adhesion when used as the bottom member of a paper cup or similar paper container and a forming method thereof. The method for manufacturing this molded paper body is to draw-process, with a punch and die, a single blank primarily of paper, and is characterized by use of a holding mechanism to press the outer peripheral portion of the blank between a wrinkle pressing member and the die upper surface, and setting the force applied by the wrinkle pressing member within an appropriate range.

  • Patent number: 8815354
    Abstract: A process for producing a heat- and pressure-resistant polyester bottle, comprising a primary blow-molding step of obtaining a primary molded article by biaxially stretch-blow-molding a preform of a polyester resin, a heat-treating step of obtaining a secondary molded article that is heat-shrunk by heat-treating the primary molded article, and a secondary blow-molding step of obtaining a finally molded article by biaxially stretch-blow-molding the secondary molded article, wherein the primary blow-molding step biaxially stretches the neck portion of the primary molded article to a size nearly the same as the neck portion of the finally molded article, and the heat-treating step does not cause the neck portion of the secondary molded article to be heat-shrunk.
