  An egg tray according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 (a) and 1 (b), the egg tray 1 according to the present embodiment accommodates eggs (mainly chicken eggs) in a plurality of recesses arranged at uniform intervals in the vertical and horizontal directions. is there. The egg tray 1 mainly includes a tray body 10 made of foamed resin. The tray body 10 is a plate-like member having a predetermined thickness, and has an upper surface 2, a lower surface 3, a front surface 4, a right side surface 5, a left side surface 6, and a back surface 7. A plurality of upper surface recesses 21 are formed on the upper surface 2 of the tray body 10, and a plurality of lower surface recesses 31 are formed on the lower surface 3 of the tray body 10.

  When eggs are stored using the egg tray 1 of the present embodiment, at least two tray bodies 10 are used, and the eggs are placed in the upper surface recesses 21 formed on the upper surface 2 of the tray body 10 placed in the lower stage. The lower surface recess 31 formed on the lower surface 3 of the tray main body 10 placed on the upper stage protects the upper side of the egg (see also FIGS. 6A to 6C described later). Note that the tray body 10 may be used as a single unit when exhibiting at a store.

  Each of the tray main bodies 10 is a molded body of a foamed synthetic resin. For example, the foam body is filled with foaming particles of a thermoplastic resin, heated, foamed, and integrally molded. The thermoplastic resin is, for example, a styrene resin, or may be a composite resin in which another resin such as an olefin resin is mixed with the styrene resin.

  As shown in FIGS. 2A to 2F, FIGS. 3A to 3D, and FIG. 4, the tray body 10 has a substantially rectangular shape in plan view, and has one side (on the front and back sides). Side) is configured to be longer than the other side (right side, left side). The four corners formed by these vertical surfaces are chamfered to be rounded. In the following description, the short side (right side, left side side) direction is referred to as the vertical direction, and the long side (front side, back side) direction is referred to as the horizontal direction.

  The upper surface recess 21 and the lower surface recess 31 respectively have a substantially hemispherical curved surface 21r (especially, see FIGS. 3A and 3D) and a curved surface 31r (especially, FIGS. 3B and 3D). Have. Also, as shown in FIG. 4, the deepest part d2 of the upper surface recess 21 and the deepest part d3 of the lower surface recess 31 are configured to be shifted by a half phase hp in the vertical direction and the horizontal direction. The phase p here is a distance between the deepest portions d2 of the upper surface recesses 21 (or the deepest portion d3 of the lower surface recesses 31) adjacent to each other in the vertical direction or the horizontal direction. In FIG. 4, the position of the lower surface recess 31 viewed from the upper surface side is indicated by a dotted line.

  The distance (that is, the phase p) between the deepest portions d2 of the adjacent upper surface recesses 21 (or the deepest portion d3 of the lower surface recesses 31) is preferably 45 to 60 mm, for example, 50 to 52 mm. Note that the vertical phase and the horizontal phase may differ by about ± 5 mm. The plate thickness of the tray body 10 is preferably 55 to 70 mm, and more preferably 60 to 65 mm. For example, the depth of the deepest portion d2 of the upper surface recess 21 is preferably 20 to 30 mm, and more preferably 23 to 27 mm. On the other hand, the lower surface recessed part 31 should just cover the upper part of an egg, and the depth of the deepest part d3 may be shallower than the deepest part d2 of the upper surface recessed part 21, for example, 15-25 mm is preferable and 18-23 mm is more preferable. .

  The upper surface 2 of the tray main body 10 has a plurality of ribs 22 that protrude upward from the four sides that are located diagonally to the upper surface recess 21. The ribs 22 are provided in a lattice shape at approximately equal intervals. The rib 22 alone has a substantially rhombus shape when viewed from above, and corners located diagonally project in the outer edge direction. Each corner of the rib 22 has a rounded shape when viewed from above, and the rib 22 on the front surface 4 side has a substantially isosceles triangular shape when viewed from above, and the surface on the equilateral side is the tray body 10. The bottom side surface forms a part of the front surface 4 of the tray body 10.

  The peripheral edge of the lower surface 3 of the tray main body 10 is configured as a flat surface 32 in which the lower surface recess 31 is not formed (see FIGS. 1B and 2B). The lower surface 3 becomes the lowermost surface when the plurality of tray main bodies 10 are stacked, and comes into contact with the floor surface or the bottom surface of the cardboard box for transportation. In this embodiment, since the peripheral part of this lower surface 3 is the flat surface 32 without an unevenness | corrugation, the tray main body 10 (egg tray 1) can be mounted in the grounding surface stably.

  The flat surface 32 of the lower surface 3 is continuous with the region between the plurality of lower surface recesses 31. As shown in FIG. 5, when a plurality of tray bodies 10 are stacked, here, when the upper tray body 10B is horizontally rotated 180.degree. On the lower tray body 10A, the lower tray body 10B is stacked. The flat surface 32 of the upper tray body 10B is placed on the rib 22 of 10A. In this manner, the substantially hemispherical upper surface recess 21, the space surrounded by the four ribs 22, and the lower surface recess 31 become an individual packaging space for accommodating one egg. In addition, 10-25 mm is preferable and, as for the height of the rib 22, 15-20 mm is more preferable. The height of the egg storage space is preferably 55 to 70 mm, and more preferably 60 to 65 mm so that the egg can be stored vertically.

  The egg tray 1 configured as described above is used by stacking a plurality of tray bodies 10A to 10C as shown in FIGS. First, a plurality of eggs E are placed in the respective upper surface recesses 21 of the lower tray body 10A, and the middle tray body 10B is placed on the lower tray body 10A while being rotated 180 ° with respect to the lower tray body 10A. Placed. At this time, since the lower surface recess 31 is configured to be shifted by a half phase hp in the vertical direction and the horizontal direction with respect to the upper surface recess 21, the upper surface recess 21 of the middle tray body 10B is the same as that of the lower tray body 10A. The upper surface recess 21 is shifted by a half phase hp (see also FIG. 4). Then, a plurality of eggs E are placed in the upper surface recesses 21 of the middle tray body 10B, and the upper tray body 10C is rotated 180 ° with respect to the middle tray body 10A. The lower tray body 10A is placed in the same direction. Here, an example in which a plurality of eggs E are stacked in two layers using three tray bodies 10A to 10C is shown, but a plurality of eggs E are stacked in three layers using four or more tray bodies 10. You may make it load more.

  According to the egg tray 1 of this embodiment, since the tray main body 10 is made of foamed resin, the strength is not lowered even when exposed to moisture, and the eggs can be stably held. Therefore, if the egg tray 1 is used, eggs can be transported and stored using refrigeration equipment that may cause condensation and get wet. Moreover, since the material itself which comprises the tray main body 10 is lightweight and has moderate cushioning property, the damage of the egg E at the time of transportation etc. can be suppressed. In particular, the upper surface recess 21 and the lower surface recess 31 are curved surfaces 21r and 31r (see also FIGS. 3 (a) and 3 (b)) and hold the egg E in a curved surface. Thus, even if a load is applied to the egg E, it is difficult to apply a partial load to the egg E, and damage to the egg can be effectively suppressed.

  On the other hand, if the foamed resin does not have a predetermined thickness, it cannot maintain the required structural strength, and is more bulky than pulp mold and general plastic, and the number of eggs that can be accommodated per unit volume of the tray body May decrease. However, according to the egg tray 1 of this embodiment, the deepest part d2 of the upper surface recessed part 21 and the deepest part d3 of the lower surface recessed part 31 are shifted | deviated by half phase hp in the vertical direction and the horizontal direction. Accordingly, when the upper tray body 10 is placed in a state rotated by 180 ° with respect to the lower tray body 10, the upper surface recess 21 of the upper tray body 10 is located with respect to the upper surface recess 21 of the lower tray body 10. , Half phase hp shifts in the vertical and horizontal directions. Therefore, the loading position of the egg E is shifted by half of the egg between the upper stage and the lower stage. That is, since the eggs E are efficiently arranged differently in the upper and lower layers, a large number of eggs can be accommodated.

  In a normal use example, the egg tray 1 is packed in a state in which the egg E is accommodated in a cardboard box B having a predetermined shape, as shown in FIGS. The egg tray 1 has a flat surface with a predetermined area on any of the lower surface 3, the front surface 4, the right side surface 5, the left side surface 6, and the back surface 7 of the tray body 10. Since there is a predetermined thickness between 31 and the rib 22, for example, if the stacked tray bodies are fixed with a binding band (not shown) or the like, they can be used as a transport box. It is possible to carry it as it is in the state shown in FIG.

  The present invention includes a tray body 10 made of foamed resin, and a plurality of upper surface recesses 21 formed on the upper surface 2 of the tray body 10 and a plurality of lower surface recesses 31 formed on the lower surface 3 are arranged in the vertical direction and The present invention is not limited to the above-described embodiment, and various modifications are possible as long as they are configured so as to be shifted by a half phase in the lateral direction. For example, in the above embodiment, the side surface of the egg arranged in the vicinity thereof can be seen from the gap between the ribs 22 on the front surface 4 side or the left side surface 6 side, but the rib on the peripheral edge portion has no gap. It may be configured as follows. In this way, since the space for accommodating the eggs is surrounded by the foamed resin, it is possible to improve the cold insulation.
