Patent number: 4549908Abstract: The incorporation of organic and FD&C pigments that meet FDA specifications for food packaging materials into resinous articles is accomplished by dispersing the pigments into a non-toxic mineral or vegetable oil formulation which contains glycerol monooleate and zinc stearate, the formulation then being added to the resin and mixed. Resinous articles colored in this manner can be utilized safely as direct food contact packaging, for example, decorative grass, which enables candies to be placed directly on the grass without incurring the expense of overwrapping the candies with a resin film which meets FDA and USDA requirements and which eliminates the hazard involved when candies are inadvertently or unknowingly placed on the decorative grass. The resinous materials which may be colored by the organic and FD&C pigments include polyolefin resins.Type: GrantFiled: November 19, 1984Date of Patent: October 29, 1985Assignee: Highland Manufacturing & Sales Co.Inventors: Erwin H.

Patent number: 4292266Abstract: Methods and apparatuses for making decorative grass or grass-like product in the form of strips of plastic material of predetermined dimensional characteristics having color, anti-static agents and flame retardants incorporated therein prior to extrusion of the resin thereby preventing rub off of the color and minimizing clinging of grass to the hands and clothes of a decorator. One method and apparatus for making the grass includes an extruder for plastic material and including a film extrusion die or a strand extrusion die. When a film is extruded, the film is cooled and slit longitudinally into strips of predetermined width. In another method, the extruded strips or strands are cooled. In all methods, the plastic strips pass through a slow godet, a drawing oven and a high speed godet to enable the strips or strands to be drawn down in width and thickness without breaking. From the high speed godet, the strips or strands are chopped to a desired length and conveyed to a storage area.Type: GrantFiled: September 12, 1979Date of Patent: September 29, 1981Assignee: Highland Manufacturing & Sales Co.Inventors: Erwin H.

Patent number: 4199627Abstract: A decorative grass or grass-like product in the form of strips of plastic material of predetermined dimensional characteristics having color, anti-static agents and flame retardants incorporated therein prior to extrusion of the resin thereby preventing rub off of the color, minimizing clinging of grass to the hands and clothes of a decorator, thus facilitating handling of the grass, and assuring that the grass will consistently exceed the flammability requirements of the Federal Hazardous Substances Act Regulations in order to be labeled "non-flammable". Processes for making the grass include an extruder for plastic material and including a film extrusion die or a strand extrusion die. When a film is extruded, the film is cooled and slit longitudinally into strips of predetermined width. In another process, the extruded strips or strands are cooled.Type: GrantFiled: July 7, 1975Date of Patent: April 22, 1980Assignee: Highland Manufacturing & Sales Co.Inventors: Erwin H.

Patent number: 4124135Abstract: A hollow, plastic Easter egg constructed of two halves connected together by a plastic living hinge of unitary construction with the two halves being retained in closed position by a latch structure in the form of a continuous peripheral rib and peripheral groove on telescoping end portions of the two halves so that the hinge line of separation between the two halves are substantially concealed. The two halves of the Easter egg may be opened or closed to enable candy, toys, figurines or any other items desired to be placed therein so that they will appear to be inaccessible but yet the egg can be opened to provide access to the items interiorly thereof with the unitary hinge retaining the two halves of the egg in connected relation when the two halves are hinged to their open position.Type: GrantFiled: December 17, 1976Date of Patent: November 7, 1978Assignee: Highland Manufacturing and Sales Co., Inc.Inventors: Erwin H. Weder, Donald E. Weder
