Definitions

  • the present invention relates to an egg tray of the kind set forth in the preamble of claim 1.
  • Egg trays of the kind referred to above are used i.a. for shipping and transportation of relatively large con- signments of eggs in boxes, of which a number are again stacked on pallets, and in containers.
  • the boxes, pallets and containers are dimensioned according to standard dimensions intended to contribute to the best possible utilization of the available transportation space.
  • a number of trays, stacked on top of each other to form a stack is placed in a box, or the stack is encased in a surrounding envelope forming a box.
  • the shape of the trays is such that the eggs are embraced below by an egg-supporting tray and above by the lower part of a further egg-supporting tray placed on top of the first-mentioned tray.
  • the total height of a finished stack equals the total height of the stacked egg-supporting trays plus the height of the additional tray being used as a cover.
  • the total height may become so great as to cause problems when the stack of trays is to be placed in a standard box.
  • the invention is based upon the recognition of the possi ⁇ bility of achieving not only a decrease in the height of a tray and hence of the total height of a given stack, but also an improved protection against damage to the eggs placed in the stack.
  • the effects of the construction of the egg pockets as set forth is that neighbouring egg pockets will overlap each other at their mutually facing side-wall regions, at the same time as the eggs, due to the egg-supporting surface being situated far down in the egg pockets, the eggs can be placed exceptionally far down in the pockets.
  • the combination of the low placing of the supporting surface and the overlapping having been achieved makes it possible to achieve such a reduction of the requisite height of the egg tray for receiving eggs, that it is no longer necessary to produce a special low tray to serve as a cover, but that a tray adapted for stacking of eggs can also be used as a cover for a stack of trays without causing problems, when the tray is to be placed properly in a box suitable for a given pallet size and a given container height.
  • the invention provides a possibility for improved utilization of the cargo volume of a container intended to receive e.g. the boxes, as this cargo volume may now be filled with e.g. eight boxes, the stack of egg-supporting trays of which are still formed from six trays instead of previously seven. This can increase the utilization of the total cargo capacity of the container by e.g. approximately 15 p.c.
  • the invention also provides for an improved transfer of pressure loads on the cover, as these loads will be distributed in an improved manner around the eggs by the pocket walls em ⁇ bracing the eggs in the uppermost layer.
  • Figure 1 diagrammatically shows a stack of egg trays formed with a view to being placed in a box-shaped pack ⁇ aging means, in which stack the uppermost egg-supporting tray is covered by a cover,
  • Figure 2 at a larger scale and viewed from above shows a number of egg pockets formed in an egg tray or an asso ⁇ ciated cover
  • Figure 3 is a cross-sectional view along the line III-III in Figure 2
  • Figure 4 shows parts of the two uppermost egg-supporting trays with an associated cover, viewed partly in section along different planes,
  • Figure 5 diagrammatically shows a second embodiment of the egg tray and an associated cover
  • Figure 6 is a cross-sectional view of some of the pockets of the embodiment of Figure 5.
  • Figure 7 is a sectional view along the line VII-VII in Figure 5.
  • An egg packaging set shown in Fig. 1 consists of a number of egg trays 10, each of which, as will be seen from Figure 2, comprises a number of pockets 16, each intended to accommodate one egg, said pockets 16 being arranged in rows 12 and 14 lying side-by-side.
  • the pockets 16 are formed from downwardly projecting parts 18 of the tray and are separated from each other by upwardly protruding parts 20.
  • the number of pockets corresponds to a predeter ⁇ mined number of eggs.
  • the trays 10 are capable of being stacked on top of each other utilizing the projec ⁇ tions 18 and 20 as supporting elements to form a stack as shown in Figure 1, that may be placed in e.g. a box or other envelope for further stacking on a pallet, and in a container.
  • the eggs are embraced by walls 24 forming the pockets 16, said walls 24 both in the trays 10 and in the cover 22 having egg- embracing abutment surfaces with a continuously curved shape, cf. Figures 2-4.
  • These abutment surfaces 26 have free end edges 28, each of which with its ends extending in an arch upwardly to a corner on a free end of an upward projection 20 between the pockets 16, said free end having a four-sided top surface 30.
  • This top surface 30 has side edges 32 following the curvature of the adjacent side wall sections.
  • a cover 22 Associated with the egg packaging set shown in Figures 1-4 is also a cover 22, likewise having pockets 16.
  • the height of the cover 22 is less than that of the egg trays 10 of the packaging set.
  • the cover 22 is shaped with a view to being placed on the top of the tray stack with its pockets 16 facing towards the pockets 16 in the next tray 10 below, cf. Figure 4.
  • the cover 22 When the cover 22 is subjected to pressure loads, the latter will be distrib ⁇ uted via the projections 20 and the adjacent continuously curved wall regions 26 and wall edges 28 around the eggs placed in pockets 16.
  • the pockets 16 have outwardly arched side wall regions 34. Further, the circumferential circles for two mutually opposing side-wall regions 34 of two neighbouring pockets 16 at the uppermost ends of the latter intersect each other as shown with broken lines 16a and 16b in Figure 5.
  • the circles 16a and 16b are superimposed upon and are smaller than the circles determining the cross- sectional shape of the associated pockets 16 themselves.
  • the especially narrow overlapping section determined by the lines 16a and 16b serves as a spacer when two trays are nested into each other for storage purposes.
  • the pockets 16 com ⁇ prise a continuously curved, annular supporting surface 26 for the eggs.
  • this tray may be placed in position with either the top or the bottom facing downward.
  • An additional advantage of the invention consists in that it will be possible to use an egg tray shaped in accordance with the invention for packaging even larger eggs, for instance eggs in the 70-gramme class, without problems arising with regard to stacking the egg trays in a standard box.

Abstract

Ensemble pour le conditionnement des oeufs consistant en un certain nombre de plateaux à oeufs (10) parallèles pouvant accueillir chacun un certain nombre d'oeufs dans chaque rangée (12, 14) et permettant de réaliser une pile qui peut être à son tour placée dans une boîte ou tout autre réceptacle. Les plateaux (10) comportent des poches ouvertes sur l'extérieur (16) selon un nombre correspondant au nombre prédéterminé d'oeufs, chaque poche (16) étant réalisée par des parties (18) faisant saillie vers le bas du plateau, afin d'accueillir un oeuf en position verticale, des parties faisant saillie vers le haut (20) étant réalisées entre les poches afin que sur deux plateaux (10) empilés l'un sur l'autre, les parties faisant saillie vers le haut (20) d'un plateau supportent le plateau supérieur grâce aux parties faisant saillie vers le bas de ce dernier (18). Les oeufs disposés sur les plateaux (10) sont entourés par des parois circonférentielles (24) réalisant les poches (16), lesdites parois (24) se coupant les unes les autres d'une poche à la suivante et comportant des surfaces (26) de butée entourant les oeufs incurvées de manière contiguë vers les extrémités libres des parties faisant saillie vers le haut (20) entre les poches (16). Ces surfaces de butée (26) comportent des rebords libres (28), dont chacun s'étend par ses extrémités selon un arc dirigé vers le haut en direction d'un angle de la face supérieure (30) à quatre côtés d'une partie faisant saillie vers le haut (20), les quatre bords (32) de ladite surface supérieure (30) épousant la courbe des parties adjacentes de parois (26). Chaque plateau est également conformé de manière à pouvoir être placé sur le sommet d'une pile de plateaux, ses poches (16) faisant face aux poches (16) du plateau (10) placé au-dessous.
