  • Patent number: 10589916
    Abstract: An apparatus includes a box including one or more side walls, each of which defines an inside surface. A bag is disposed in an internal region defined by the box. Drinking water is contained in the bag, the water being non-alcoholic. The bag is adapted to protect the water from contaminants, tastes, and odors, each of which originates from either the bag itself or a source external to the bag. A water-resistant coating may be applied to the respective inside surfaces. When condensate forms on the bag, the water-resistant coating at least resists absorption of the condensate into the one or more side walls. The apparatus may include a spout, which permits the water to be dispensed from the bag for human consumption. In an exemplary embodiment, the water is treated with a sanitizing additive such as, for example, ozone. The apparatus mitigates the environmental impacts of drinking water packaging.

  • Patent number: 7208209
    Abstract: The invention teaches a container formed from a synthetic substrate. The synthetic substrate is substantially tear resistant and includes polyethylene and inorganic minerals. The synthetic substrate is cut and scored to form a container blank of desired shapes and sizes. At least some portion of the container blank is coated with an adhesive. The container blank is folded and or otherwise manipulated so that at least some portion of the container blank is secured to another surface of the container blank to form a partially closed container with at least one opening.

  • Patent number: 7019054
    Abstract: A formulation, and a process for making same, is disclosed which is useful as a coating or treatment for imparting oil and grease resistance to an underlying substrate. The formulation does not contain any fluorochemicals. At the same time, however, the formulation provides oil and grease resistance properties that are equivalent to known coatings and treatments which contain fluorochemicals, particularly those coatings which are permitted to come into direct contact with food products. Therefore, the formulation of the present invention is ideal for use as a coating for paper and paperboard, including paper packaging such as that utilized in food wrappers, food containers, food receptacles and the like, and for other shaped articles. The formulation is also useful as a coating or treatment for providing release properties to an underlying substrate without the use of silicone.

  • Patent number: 6949274
    Abstract: Sealant is statically applied to the edges of panels by placing a sealant on the inner surfaces of the walls of a container holding the panels. A shrink wrap sleeve is preferably applied to the panel filled containers, causing contact between the inner surface of the container and panel edges, such that the sealant is transferred to the edges of the panels. Further transfer occurs during handling of the container, due to movement of the panels in the container and contact between the sealant and panel edges.

  • Patent number: 6926197
    Abstract: A drinking cup has sandwiched between an inner paper liner and an outer paper shell a ridge structure which has its ridges running peripherally, i.e. perpendicular to the axis, e.g. in the form of corrugations, a mesh or a cell network and can be partially filled with a phase-transition material to maintain a maximum temperature at the exterior of the shell for a given hot temperature of the liquid within the cup.

  • 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.

  • Patent number: 6854639
    Abstract: A carton blank may be formed from a first sheet of relatively rigid material and a second sheet of relatively flexible fluid impervious material. The second sheet of relatively flexible fluid impervious material may cover some but not other portions of the first sheet of relatively rigid material in order to facilitate gluing of the other portions of the first sheet of relatively rigid material when the carton blank is assembled into a carton.

  • Patent number: 6740373
    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.
