Definitions

  • the present invention relates generally to molded pulp articles, and more particularly to an improved molded pulp egg carton in which selected portions of the egg cells are provided with increased strength and improved cushioning characteristics.
  • Eggs are widely marketed throughout the world in cartons that hold la dozen eggs each, and among the most widely known type of egg carton, is one that is produced trom molded pulp. Molded pulp egg cartons are produced on pulp molding machinery in a conventional manner, wherein the carton is deposited by suction imposed .within a die of desire-d coniiguration and a slurry of pulp is deposited on the exterior of the die. Ilhereafter, in order rto enhance the appearance of the carton as well as to substantially soften the material from which the carton is produced, the article is pressed between mating dies.
  • the eggs are held in egg cells, separated from each .other by ⁇ saddle portions between adjacent cells and verticals posts lhaving four cell-s Aformed .thereabout
  • the eggs are generally in contact with the walls of the cells .and thus shocks to the exterior of the carton result in force being transmitted to the eggs through the walls of the carton, accordingly resulting in the small amount of egg breakage that presently exists.
  • molded pulp egg cartons may be produced to accommodate all sizes of eggs, however, to store and tool up to produce the range -of sizes of egg cartons necessary to accommodate all the single variations is neither practical nor economical.
  • the shipping cartons in which egg cartons are shipped and stored generally have uniform exterior dimensions, Yand therefore there has been a constant attempt to maintain exterior dimensions of the egg cartons relatively uniform.
  • there ha-s lbeen a constant research to develop a substantially universal carton which will accommodate and protect substantially all ranges of sizes of eggs without materially changing exterior dimensions of the carton, and it is toward this end which the novel carton and method of the present invention is directed.
  • the primary object of the present invention is to prolCe vide a novel substantially universal molded pulp egg cart-on in which egg movement and rattle are substantially reduced, to accommodate for varying dimensions of the eggs and reduce accidental .breakage to a minimum.
  • a further object of the present invention is to provide an egg carton which includes features which permit ready denesting or separation of a stack of egg cartons, one from the other.
  • a still further object of the present invention is to provide a molded pulp egg carton in which both large and small dimensioned eggs will be adequately supported, and the eggs will be supported in a relatively soft support surface on support structure to retain the-m in a re1- atively protected and xed position Within an egg cell and both relatively large and small sized eggs can be readily accommodated in the same carton.
  • Still another object of the invention is to provide a molded pulp egg carton which includes a cell structure having relatively rigid and reinforced outer walls to protect against external shock, and a relatively soft and resilient inner support surface for readily absorbing shock transmitted to the eggs from the outer wall.
  • Yet another object of the present invention is to utilize a novel reforming method vfor -molded pulp egg cell support structure whereby the nature of the egg support surface, due t-o the fiber character of the material used to produce t-he car-ton, is such that certain ber porti-ons are substantially softened and reoriented to a degree to aiford in a sense mechanical movement between integral and reoriented ber.
  • An-d a still further object -of the present invention is to provide, in a novel egg cell structure for -molded pulp carton portions, substantially tangential contact with eggs in the cell so that there is a minimum of sticking of the eggs in a cell due to leakers or broken eggs whereby eggs may be readily .removed yfrom the cel-ls.
  • Yet another object of the present invention is to prov-ide a novel cell structure in molded pulp egg cartons of a capacity different from the conventional onedozen egg capacity.
  • Still another object of the present invention is to provide a novel carton of the char-acter involved which includes a novel lid end wall support and ventilation structure which aifords ithe necessary strength, rigidity and load transmittal characteristics for cartons of the character involved.

  • FIG. 11 is an enlarged horizontal section taken substantially on the plane of lines 1111 of FIG. 7, showing the initial forming step which generally is accompanied by considerable pressure and heat applied between mating pressing dies, and illustrating the manner in which the bers at the cushioning are reoriented, the inner surface bers being subject to greater tension than those in the outer surface of the cushioning area;
  • FIG. 12 is an enlarged horizontal section taken substantially on the plane of line 12-12 of FIG. 8, showing the manner in which the cushioning area is reformed between mating dies to subject the outer surface fibers to greater tension than those on the inner surface as mentioned with respect to FIG. 11
  • FIG. 13 is an enlarged horizontal section taken substantially on the plane of line 13-13 of FIG. 9, illustrating the manner in which the cushioning area tends to assume a substantially planar condition due to the memory effect caused by the step of FIG. 1l, shown by phantom lines, the cushioning area comprising super soft fibers on both the inner and outer surfaces of the cushioning area;

Intersecting pairs of the saddle portions 36, 38 substantially define edge portions of frusto-pyramidal separator posts indicated generally at 40 which terminate in a substantially square top portion 42, the corners of which are disposed in alignment with the saddle portions 36 and 38.
  • the upper portions 42 of the separator posts 40 as seen in FIG. 3, will abuttingly engage the inner surface of the planar top 22 of the cover member 20 for absorbing force on the cover member and transmitting it through the post to the bottom portions of the cells Without injury to the eggs contained therein.
  • the egg receiving section 12 includes a peripheral marginal edge portion 44, portions of which engage the peripheral bead 26 of the cover member when the carton is closed in the manner shown in FIG. 2.
  • the posts are eliminated at portions 46 at the opposite ends of the carton; however, the egg supporting structure in the endmost cells functions in substantially the same manner as that of the innermost cells.
  • Each of the cells 34 comprises a transverse bottom 48 preferably including a cushioning button 50.

  • the segments 52, 54, 56 and 62 are generally not engaged by an egg disposed in the cells unless than eggs are particularly large or of a golf-ball shape, for example.
  • Each of the cells affords a substantial four-point support for the eggs disposed therein.
  • This four-point suspension of the eggs is afforded by a pair of similar cell forming segments 64 and 66 which have a lower portion having a convex cross section, when viewing the interior of the cells, this convex cross section merging into vertically extending and elliptical or tear-Shaped pressed areas 68 and '70, respectively.
  • the elliptically shaped sections 68 and '76 may have vertically extending therein inwardly pressed rib portions 72 and 74 respectively, which in effect reduce the surface exposure to the eggs in the ⁇ cells to prevent sticking of eggs in the case of a leakerj for example.
  • the segments 62, 64 and 66 provide a relatively rigid wall in the cells, however, the pressed areas 63 and 7i) are relatively sof and together with the ribs 72 provide a minimum of egg contact.
  • the convex surface may have an arc which is shallower than that found in most eggs, and thus minimum egg Contact is insured.
  • This relatively rigid outer Wall construction for the cells aifords protection of the eggs due to lateral shock occurring during handling, packing and shipping.
  • the frusto-pyramidal separator posts 4@ include substantially planar post forming segments 76 and 78 in the respective cells 34, and four adjacent cells including opposed pairs of segments 76 and 78, as clearly seen in FIG. 1, which -together with the top portion 42 form one of the frusto-pyramidal separator posts. It will be noted thay the opposed pairs of post forming segments 76 and 78 converge into the substantially rectangular or square upper end portion 42 of the separator post.
  • the cell segments 62 extend in planar relation down to the cell bottoms and are disposed at a greater angle with respect to the vertical than the adjacent convex segments 64 and 66. Stated in another way, the segments 64 and 66 are more vertically disposed than the segments 62.
