Definitions

  • the present invention relates to an egg tray according to the preamble of claim 1.
  • Such an egg tray is known from US-A-2 662 659.
  • a further egg tray or egg pack is known from GB 1086941.
  • the pockets are provided with ribs in their side walls. These ribs serve to prevent packs in the stack from sticking together during the transportation of packs without eggs. Furthermore, these ribs give further strength and are in contact with the eggs in such a way that the latter are situated at some distance from the wall.
  • Such reinforcing ribs must be distinguished from concave or convex parts for supporting eggs. Such parts are disclosed in, for example, FR 11 72 220A. Owing to their relatively great “width”, they do not provide reinforcement. For the latter, “sharper" ribs are required, which on contact with the egg would damage it.
  • the polygonal body of revolution described above corresponds to an egg to be placed in the carton.
  • the reinforcing ribs for obtaining the increase in strength are of a "sharp" design.
  • they have a relatively low thickness, which is preferably less than double the average material thickness of the egg tray. More particularly, this thickness is less than 4 mm, and more particularly is less than 3 mm. This means that a considerable reinforcement between end face and side face can be obtained.
  • the reinforcing; ribs comprise indentations. That means that to the extent to which the ribs project inward into the pockets or project outward out of the pockets a corresponding opening is provided in the opposite wall of the end face. In other words, the wall thickness remains substantially uniform. This means that there is little or no increase in material used for increasing the strength.
  • the reinforcing ribs are provided on the inside of the pockets. Furthermore, according to an advantageous embodiment of the invention, these reinforcing ribs extend not only over the end face, but also into the adjacent side wall. In other words, a sort of strut is obtained between side wall and end wall.
  • the projections of the egg tray merge on its underside into the pockets, and side faces are always placed between two projections, and the reinforcing ribs extend from the centre of said side faces. If the pocket is bounded by four projections, four reinforcing ribs are present.
  • the ribs preferably extend over at least a quarter of the end face of the pockets. If the ribs also extend over the side face between the projections, according to an advantageous embodiment these ribs extend over at least one third, and more particularly at least half the height of said side faces.
  • the egg tray according to the present invention is shown by reference numeral 1 in Fig. 1.
  • This egg tray is to be filled with eggs 2.
  • the tray consists of a number of projections 3.
  • a pocket 4 is bounded between four projections 3.
  • Side faces are situated between the projections. These side faces are indicated by 5 (the transverse wall) and 6 (longitudinal wall).
  • An end face 7 is bounded on the underside of the projections or pocket 4.
  • the projections are provided with a supporting face 9 on the top side. In the in-use positions filled trays are placed on top of one another. By always turning the trays a quarter turn relative to each other, stacking is possible and the end face 7 of the one tray comes into contact with the supporting face 9 of the following tray.
  • Reference numeral 15 indicates the concave faces on which the egg rests. These are relatively broad faces that provide an optimum contact face between egg and pack, for the purpose of transferring loads on the egg to the pack by way of as large a surface as possible, in order to prevent breakage.
  • ribs 8 extend, as can be seen from Fig. 2, both in the transverse walls 5 and longitudinal walls 6 respectively and in the end face 7.
  • h the total height of the transverse wall 5 and longitudinal wall 6 respectively
  • a the height of the rib 8 is indicated by a. It is found that this height is approximately half the height h.
  • the width of the end face is indicated by b, and the distance over which the rib 8 extends is indicated by c. It is found that c is greater than a quarter of b.
  • the thickness of the reinforcing rib at its end face is indicated by d. Said thickness is less than 4 mm, and is preferably approximately 3 mm, in other words approximately double the average wall thickness of the egg tray. After the boundary with the wall of the egg tray, the interior of the reinforcing rib will be hollow. After its free end, away from the wall, the rib will be relatively solid in its interior.
  • the underside of the tray is shown in Fig. 3. It can be seen from this figure that at the position of the ribs 8 indentations 19 are made on the side lying opposite. In other words, the ribs are not simply achieved by applying more material, but by a radical change in the design of the inside shape of the pocket.
  • Fig. 4 shows the positioning of an egg relative to the reinforcing rib. It can be seen from this figure that the egg rests upon the concave faces, as shown in Figs. 1 and 2, and lies at some distance from the reinforcing rib, since the reinforcing rib is so "sharp" that contact with the egg would probably lead to breakage.
