  • Patent number: 5439110
    Abstract: A carton containing two tiers of necked bottles. The bottles in the upper tier are inverted from the bottles in the lower tier, with the bottle necks of the upper tier extending between the bottle necks of the lower tier. The bottle necks extend through spaced separator sheets containing flaps that prevent contact between adjacent bottle necks. Partitions prevent contact between adjacent bottles in each tier. The carton is sloped in to a relatively small top panel, and the top panel is provided with a handle.

  • Patent number: 5435954
    Abstract: A method for producing articles comprised of reinforced composite materials including primarily wood or cellulosic fiber and plastic is disclosed.. The wood fibers are comminuted to substantially a specific thickness and classified according to length. Plastic is comminuted and mixed with wood fibers to form a reinforced composite mixture in predetermined ratios. The composite materials form the main structural or bonding components of the finished article. Other chemicals, such as a coupler can be added, as can other structural components, such as fiberglass. The mixture is deposited onto a mold when forming articles having deep drawn portions, and subjected to sufficient temperature and pressure to cause the composite mixture substantially to assume the mold form. The process variables disclosed can be selectively modified to produce predetermined physical characteristics in the finished article, such as strength, thickness or prestressed qualities.

  • Patent number: 5427241
    Abstract: A carrier having an end panel construction that snaps into place during formation of the carrier and has the ability to follow the contour of adjacent curved or beveled packaged articles. Gusset tabs foldably connected to the lower end panel flap and adjacent lower glue flaps cause the flaps to snap into place. The lower glue flaps are continuations of the lower portion of the side panels and follow the contour of adjacent curved packaged articles. Bevel panels between the lower glue flaps and the top panel enable the carrier to fit tightly about the upper tapered portions of the corner articles in the carrier.
