Definitions

  • the present invention relates to a resilient support for hens eggs to be packed, and the invention has special reference to a container of fibrous material for hens eggs, in which the eggs are arranged between an upper part and a bottom part of the container, the bottom part being provided with individual cells constituting seats for the lower portions of the eggs and comprising an egg supporting portion shaped like a truncated cone-like body wtih an inward concavely curved generatrix.
  • the object of the invention is to indicate a support of the kind in question in which the cells are so formed that the eggs are supported in such a manner that the abutment pressure between the eggs and the adjacent surface of the cells is distributed uniformly over a relatively great area independent of the size of the eggs.
  • the said cells Up to the present the said cells have been shaped in accordance with the most common form of hens eggs. A normal egg then abuts nearly the whole area of the walls of the cell and is well supported, whereas a more elongated egg rests on its narrow end in the cell and a rounder egg hangs on the upper edge thereof. So in the last two cases the contacting areas are very small and the eggs run a risk of being crushed when the container is shaken or subjected to rough handling.
  • Containers are also known having angular cells, e.g. truncated pyramidal cells, or cells provided with inwardly projecting ribs.
  • the purpose of such a design is to provide a number of spaced supporting areas capable of yielding.
  • the curvature of the generatrix of the egg supporting portion of the cell is less than the curvature of the adjoining surface of any of the eggs to be packed. This results in a very lenient support for the eggs, since the support is in the form of a belt-formed surface in the cell. The vertical location of the said surface will depend on the shape of the egg.
  • FIG. 1 is a vertical cross section through the container
  • FIG. 2 is a plane view of part of the bottom part of the container.
  • the container may be manufactured by precipitating fibre pulp by means of suction on a mould having a reticulated or perforated surface, so that the container will have substantially the same thickness all over.
  • the container consists of two halves, viz. a lower half and an upper half 12, which are hinged together along a fold line 14.
  • the lower half is provided with a number of cells 16, the number of cells being adapted to the desired size of the container, whereas the mutual distance of the cells is arbitrary.
  • Each cell is deisgnated to receive the lower portion of an egg.
  • Each cell 16 has a main portion 16a and a lower portion 16b.
  • the main portion is in the form of a truncated cone-like body having an inwardly concavely curved generatrix.
  • FIG. 1 shows three differently sized eggs A, B and C arranged in the cells 16 and shown in dot and dash lines.
  • A is the largest egg in a certain weight group
  • C is the smallest
  • B is the slenderest.
  • the egg is supported by a belt-formed supporting face, because the egg and the supporting face both are curved to the same side, and because their radii of curvature only differ slightly.
  • the vertical location of the supporting face will vary dependent on the size and the shape of the egg.
  • the described shape of the supporting face is a Very appropriate one, since an egg can resist great pressure through forces distributed evenly along its surface. It is also an advantage that the said supporting face has a certain axial height, even though the height is small. The belt shaped supporting face will be retained even if the egg is tilted in the cell when the container is shaken.
  • the lower portion 16b of the cell is so shaped that the egg normally does not touch its inner surface.
  • the bottom of the lower portion is slightly dome-shaped so that it can be pressed slightly downwards when touched by the narrow end of an egg without coming: into direct contact with the surface supporting the container.
  • the upper half 12 is troughshaped, but it may have any expedient form. It may be provided with supporting surfaces in a manner known per se, said surfaces being e.g. arranged on hollow studs projecting downwards between the eggs.
  • the shape of the upper part of the container is not of decisive importance for the invention.
  • This part need not be hinged to the bottom part and need not be connected to this part at all.
  • Both parts may be in the form of so-called egg-trays which may be arranged between layers of eggs in a shipping container or egg crate.
  • a resilient support for hens eggs to be packed comprising a structure provided with a number of cells constituting seats for the lower parts of hens eggs to be packed, each cell including an egg-supporting part having a truncated, generally cone shape with an inwardly concavely-curved generatrix curved according to an arc of a circle being located above the level of the cell and at a distance of about 57 mm. from the axis of the cell.
