  • Aligned with and included at opposite ends of the row of posts are upwardly extending hollow members or half posts 26a and b.
  • members 26a and b terminate at substantially the same elevation as the posts 25a-e.
  • each post which depends from the top of the post and interconnects opposed depending and outwardly flared sidewalls of the post.
  • Each rib 27 in the illustrated embodiment is disposed at an angle with respect to the longitudinal axis of the row of posts.
  • each cell 12 in both rows A and B has formed therein an elongated upwardly extending flute 28.
  • the flute commences from the bottom 30 of i the cell and tapers upwardly therefrom and blends into the exterior surface forming the upper portion of the cell.
  • elongated upright shoulderlike projections 31 Disposed laterally on either side of flute 28 are elongated upright shoulderlike projections 31, see FIGS. 1 and 3. The function of these projections will be discussed more fully hereinafter.
  • the upper edge 15 of the tray section rear wall 16 is provided with a plurality of raised portions or lands 15a, see FIGS. 3 and 5.
  • One such portion is aligned between each pair of adjacent cells 12 comprising the rear row B of cells.
  • the outwardly facing side of each portion 15a is set inwardly a short distance from the hinge section 14 so that when the latter is disposed in its upright position, see FIG. 5, there will be no interference between the hinge section 14 and the portions 15a.
  • the hinge section I4 the illustrated embodiment is provided with a plurality of longitudinally spaced protuberances 32 which are adapted to extend into the carton interior when the cover section 13 is in its closed position.
  • the protuberances 32 are disposed between a pair of elongated substantially parallel fold lines 33 and 34.
  • Fold line 33 joins the lower edge 17 of the back side 18 of the cover section 13 with one elongated side of hinge section 14, and fold line 34, on the other hand, joins the-upper edge 15 of the tray section backwall 16 to the other elongated edge of hinge section 14.
  • the protuberances 32 are adapted to snugly fit between adjacent portions of the cover and tray sections, which portions 17 and 15 assume a substantially superposed relation when the cover section is disposed in its closed position.
  • the portions 15 and 17 coact with the hinge section protuberances 32 so as to prevent the cover section from being overclosed or out of alignment with the tray section 11.
  • Cover section 13 is provided with a centrally disposed, downwardly projecting post 35.
  • the extent to which the post depends from the top panel 22 is such that the lower distal end 3511 of the, post abuts the top of the upwardly extending post 25c formed in tray section 11.
  • cover section 13 is provided with inwardly and downwardly extending projections 36 and 37 which are formed in the end walls 21 thereof.
  • the center post abuts post 25c and the projections 36 and 37 abut members 26a and b, respectively.
  • an elongated depression 38 Extending forwardly and rearwardly of the center post 35 is an elongated depression 38, the ends of which terminate at the front walls and backwalls of the cover section.
  • the depression 38 provides added stiffness for top 22. If desired, however, the depression 38 may 'be omitted or the shape thereof may be varied from that shown.
  • the front side of the cover section 13 is reinforced by a bracing flange 40 which is hingedly connected by means of a fold line 41 to the upper edge of the front wall 23 of the tray section 11.
  • the upper edge 40a of flange 40 is bent inwardly a slight amount so as to conform substantially to the shape of the interior surface of the juncture between the cover section front wall 20 and top panel 22, see FIG. 5.
  • the flange is disposed in its upright bracing position, it is disposed behind the cover section front wall.
  • the upper edge of the flange 40 is provided with a concavity 42 at the center thereof so as to avoid any interference between the cover section depression 38 and the upper edge 40a of the flange 40 when the cover section and flange are in the positions shown in FIGS. 1 and 5.
  • a ledge 43 Spaced a short distance above fold line 41 and disposed on the front face of flange 40 is a ledge 43, see FIG. 5, on which the lower edge of the cover section front wall 20 rests when the cover section 13 is in its fully closed position.
  • the lower edge of the front wall 20 is recessed at 44. By reason of the recess 44, the remainder of the lower edge of the cover section front wall 20 and end walls 21 are able to contact the upper edge of the respective walls 23 and 24 of the tray section 1 1.
  • FIG. 4 illustrates an important feature embodied in the improved carton l0; namely, that the top wall or panel 22 of the cover section 13 and the bottoms 30 of the cells 12 of the tray section 11 are disposed in coplanar relation, when the cover section is in its fully opened position.
  • the relative disposition of the cover and tray sections, shown in FIG. 4, is that which they assume when the carton is disposed on the drying conveyor during the manufacture of the carton, particularly when the latter is formed of molded pulp.
  • distortion or warpage of the carton during its drying cycle is reduced to a minimum thereby reducing the number of rejected cartons or seconds" which might otherwise result.
  • FIG. 4 also illustrates that the portions 45 of the tray section ll, which interconnect adjacent cells 12, are of solid riblike construction thereby enhancing the rigidity of the tray section and improving the denesting characteristics of the carton.
  • FIG. 6 it will be noted that the abutting end 35a of the post 35 is also reinforced or rigidified by a solid rib 46.
  • an improved carton for fragile articles whichprovides superior top to bottom strength when the cover section is in its closed position; minimizes distortion during manufacture of the carton; permits accurate and sustained alignmentbetween the cover and tray sections when they assume a closed position; improves the stability of the loaded cartons when they are arranged in stacked relation; and reduces checking between adjacent eggs in the tray section during loading thereof or during normal handling of the loaded carton.
  • a carton for fragile articles comprising a tray section having upright front walls and backwalls interconnected by end walls, the upper edges of said tray section walls forming a supporting ledge; a cover section having a top panel and front walls and backwalls depending therefrom and end walls interconnecting the front walls and backwalls of said cover section, the lower edges of said cover section walls forming a supporting ledge; and a hinge section hingedly interconnecting the backwalls of said cover and tray sections whereby said cover section is movable into and out of a closed substantially superposed position with respect to said tray section, and the supporting ledges of said sections are in registered relation with respect to one another; the end portions of said tray section being provided with upwardly projecting members spaced inwardly from the outer periphery of said tray section ledge, said members, upon said cover section being moved to said closed position, slidably engaging the interior surfaces of the cover section end walls and guiding said cover section into registered overlying relation with respect to said tray section; the end walls of said cover section being provided with in
  • said tray section includes a plurality of article-accommodating cells arranged in side-byside relation and forming a row adjacent said hinge section; and said hinge section includes a plurality of longitudinal spaced hollow protuberances, all of said protuberances being aligned between adjacent cells of the row and engaging said cover and tray sections in a like manner when said cover section is in a closed position.
