Definitions

  • the invention relates to an egg packaging with a lower part and a top that over one at a rear Longitudinally arranged joint foldable with the lower part is connected, wherein the lower part several arranged in rows Has cells for taking eggs, which are considered semi-ovoid domed recesses are formed.
  • Egg packaging is known from obvious prior use, which consists of a lower part and an articulated one over it Hinge arranged upper part consist.
  • cells are arranged in rows to hold eggs.
  • the Cells are designed as recesses in the form that are arched are that they have an approximately egg-shaped shape on the inside to have.
  • the egg packaging can optimally the egg Protect against damage from impacts.
  • the overall structure the egg packaging is not weakened. Because the egg packaging can only fulfill its protective role if it is sufficiently rigid itself.
  • the invention has for its object an egg packaging of the type mentioned at the beginning to create the one as possible high protection for the eggs to be eaten with a low production engineering effort connects.
  • the lower part in the case of egg packaging with a lower part and a top that over one at a rear Longitudinally arranged joint foldable with the lower part is connected, wherein the lower part several arranged in rows Has cells for receiving eggs that are semi-ovoid-shaped Recesses are formed, provided that the semi-ovoid-shaped depressions in one area have at least one bulge below the equatorial plane.
  • the horizontal plane of the Understood in part, in the amount of the depressions of the Egg cells have their largest diameter.
  • Such an area is present here under an arch the recessed shape understood that between two neighboring Zeros of the curvature lies in the range between the zeros do not have the same sign as the middle Has curvature of the mold cavity.
  • the essence of the invention is based on the idea with the invention Arching an elastic storage of the egg to allow in the lower area of the mold cavity.
  • the Invention has recognized that with such an arching Form depression in a strikingly simple way an elastic Element can be created on which the eggs resemble a "Pillows" rest. This gives better shock protection, which is particularly advantageous when transporting.
  • the arching according to the invention still has the advantage that the Eggs can be packed faster. Because through the shock absorbing Effect of the arching in the lower area of the cell the eggs are slowed down more gently when inserted than when conforming shape known from the prior art the cell. This can result in the same load on the eggs used a higher speed when inserting the eggs become. This results in an advantage in terms of productivity of packaging.
  • the invention Arching also has the advantage of being stiffening works for the entire cell and thus the egg packaging gives more stability overall.
  • the curvature is preferably spherical. It has it has been shown that such a spherical design is a special one has good shock-absorbing function and therefore a forms a particularly effective "pillow" for the eggs in the cell. In addition, the spherical design has the advantage that they're fairly simple in terms of production is to be produced.
  • the radius of curvature is preferably the arching is -1/3 to -2 / 3 times the mean Radius of curvature of the mold cavity. At this ratio it gives there is a favorable size relation between the arching and the recess, so that the arching at the same time acts as a "cushion" as well as a stiffener.
  • the bulge in the lower half preferably formed in the lower third of the mold cavity.
  • Arching in the mold cavity ensures that the The weight of the ice rests largely on the bulge. This both protects the bumper from hard settling or dropping the packaging as well as maximum protection of the ice when inserted quickly reached in the mold cavity.
  • the Arching preferably in the middle of a counter-arch.
  • a such counter curvature has the effect that the contact surface enlarged with the egg inserted into the cell.
  • the arch according to the invention can better adapt to the one used Nestle the egg. The load on the egg thus spreads over a larger area, so that the used Egg is even better protected.
  • An egg packaging according to the invention essentially exists from a lower part 1 and a cover part 2, which on a a rear long side of the egg packaging arranged Hinge 3 are hinged together.
  • the lid part 2 is between an open position in which it is is pivoted backwards by about 180 °, and a closed one Position (shown in Fig. 1) pivotable.
  • a closure device 4 provided to it Keeping it securely in its closed position is one front long side of the egg packaging a closure device 4 provided.
  • the egg packaging according to the invention is preferably made in one piece from a fibrous material. The production can be carried out in a manner known per se by a wet molding process with or without subsequent Re-stamping is done.
  • the lower part 1 has a plurality of shape depressions Cells arranged in two rows of three cells each are.
  • the cells are as the shape of a halfway up cut-through ice (semi-ovoid) with shape depressions 12 trained.
  • In the illustrated embodiment is the area of the largest diameter of each mold recess 12 coincides with the upper edge of the lower part 1.
  • the diameter of the mold depressions decreases towards the bottom 12 until they finally come in at their lower end leak a foot 13.
  • Adjacent recesses 12 are by post 14, which is integrally formed with the lower part 1 are separated from each other.
  • Eggs used are shaped by the shape of the mold and through the posts 14 securely in their respective Form depressions positioned so that they do not face each other touch and therefore not damage.
  • the mold recesses 12 face directly in their lower half Four arches 15 each above the foot 13 on. These four indentations 15 are per mold recess 12 evenly distributed over the circumference, so that each two domes 15 face each other.
  • the vaults 15 are dimensioned in the illustrated embodiment such that their radius of curvature is about -0.5 times the mean Radius of curvature of the recesses 12 is.
  • the Interaction between the mold cavity 12 and that in it Eggs 5 to be used can best be seen from FIG. 3, in which a cross section through the lower part 1 according to the shown in Fig. 2 with the number III line is.
  • the structure of the Form depression 12 explained from below.
  • the foot 13 is provided at the lower end of each mold recess 12.
  • This has an annular groove 14 on its underside, which is an elevation from below into the interior of the Form depression 12 extends. It serves to make the top larger Position eggs within mold cavity 12; with smaller eggs it can happen that the ring groove 14 does not come into contact with the tip.
  • Closes at the top the arch 15 according to the invention attaches itself to the foot 13.
  • you Radius of curvature is the mean radius of curvature of the mold cavity 12 and thus also the curvature of the insert Ice 5 opposite.
  • the mold recess 12 has lubrication areas 11, whose curvature is selected so that the shape of the recess 12 as a whole gets a semi-ovoid shape.
  • the radius of curvature of the sliding area 11 is dimensioned such that at Eggs of medium size a flat plant of 5 on the egg Form depression 12 is achieved in this lubrication area 11.
  • the egg 5 can thereby be "full” in the respective shape recess 12 are held.
  • the arch 15 bulges the curvature of the ice 5 and has a due to this design Elasticity so that it can be deformed. This creates a shock-absorbing effect in relation to what is to be recorded Egg 5.
  • the four spread over the circumference Arches 15 stiffening for the entire mold recess 12. This makes the egg packaging overall more stable, so that it can better perform its protective function.
  • the egg packaging according to the invention is therefore not the egg packaging according to the invention only thanks to the arch 15 according to the invention better in its Mold recess 12 held, which makes the egg better from damage is protected by impact, but also the egg packaging overall is more stable, making the egg better can protect. It is understood that the desired properties the arching in terms of elasticity due to size and number of indentations 15 per cell 12 can be set can. The number of shown in the embodiment four is only an example.
  • Doming 15 is provided with a counter-arch 16. This is preferably provided in the middle of the arch 15 and dimensioned so that they adhere to the shell of an average Ice hugs. This improves the Contact between the egg inserted in the mold cavity 12 5 and the arch 15, so that due to the larger Contact area a lower area load for the sensitive Eggshell results.
  • the egg packaging makes it possible better protection for the ingested eggs.
  • the arch 15 according to the invention with or without counter-arch 16 is in the illustrated embodiment in the lower Area of the mold recesses 12 arranged. This is due to the one considering that with it a large part of the weight of the inserted eggs 5 rests on the concavities 15, which gives the eggs better protection against shocks.
  • the arrangement of the bulge 15 is based on the consideration that the eggs 5 inserted from above into the lower part 1 be and the dome 15 at a depth as low as possible Arrangement within the mold recess 12 as a buffer serve in relation to the insertion movement of the eggs 5.
  • the vaults are 15 arranged in pairs opposite each other. This will achieved that the eggs 5 at a higher speed than in the known egg packaging in the lower part 1 can be used. This has the additional effect that productivity in egg packaging increases.
