Definitions

  • the invention relates to a packing for a number of eggs or other fragile or delicate objects, comprising a lower part with seats for the objects and a cup-shaped upper part, generally hinged together at one edge.
  • Packings of this kind are known, in which the lower part has individual seats for the lowermost portions of the objects, whereas the upper part is formed with a fiat bottom and an oblique lateral wall.
  • the said parts en close and protect the objects, when they are folded together.
  • the packing in question is preferably designed for eggs and will be referred to in the following mainly as a packing for such.
  • the design of the packing is determined by its usability for transporting as well as retailing the eggs.
  • the fiat bottom of the upper part constitutes a plane surface, which is suitable for pasting on a label or for printing, as a means of indicating the nature and origin of the contents.
  • the primary object of the present invention is to stiffen the flat bottom of the upper part and at the same time to improve the guiding of the uppermost portions of the objects.
  • Another object of the invention is to provide a packing of the kind described and having the properties just mentioned without materially increasing the weight of the packing.
  • a further object of the invention is to utilize certain parts already present for obtaining the main object as locking members serving to maintain the packing in closed condition.
  • a flap which at its free edge carries sonically-shaped projections, serving as distance members between the lower part and the flat bottom of the upper part, when the flap has been folded inwards, and also serving as guiding members between the uppermost portions of the objects.
  • Such a packing requires approximately 50 percent more material than a simple packing consisting merely of an upper part and a lower part.
  • Another known packing consists of a lower part with individual depressions and with two lid portions, both of which are trough-shaped with fiat bottoms and oblique lateral walls, and which are hinged to opposite sides of the upper part.
  • the width of the lid portion, which is first folded against the lower art, is half the width of the lower part, and one oblique lateral wall of the said portion will therefore constitute a partition, which rests upon the lower part and divides the space above same into two halves, so that to some extent it prevents the eggs from capsizing and stiffens the superjacent complete lid against being depressed.
  • the stiffening of the uppermost lid is not fully effective, as the lowermost lid may yield to pressure.
  • Still another constructional form is known, wherein projections are provided on the flat bottom of the upper part, said projections extending downwardly into the closed packing to prevent the eggs placed therein from overturning.
  • the said projections must be hollow, whereby the fiat bottom is interrupted by apertures, so that a large continuous surface for consumer information cannot be obtained.
  • the flap indicated by the invention shall not occupy part of the hollow space of the packing, the flap suitably comprises an oblique wall, which extends from the hinge line of the flap to a plane wall carrying the projections.
  • the constructional form of the packing indicated by the invention affords the possibility of securing or locking the upper part in closed condition, in that the oblique wall of the flap and the oblique lateral wall of the upper part adjacent thereto in the closed condition of the packing are provided with mutually cooperating locking members.
  • FIG. 1 shows one embodiment of a packing according to the invention, as seen from above in unfolded condition
  • FIG. 2 is a cross section through same on the line IIII in FIG. 1,
  • FIG. 3 shows on an enlarged scale a similar cross section, after the flap has been folded upwards over the lower part
  • FIG. 4 shows a similar cross section, after also the upper part has been folded upwards over the lower part as well as the flap.
  • the shown packing may have been produced by precipitation of fibre pulp by suction through a mould with reticulated or perforated surface, whereby substantially the same thickness of wall all over is imparted to the packing.
  • the packing can also be made of other materials, e.g. plastic material, with the use of moulds, when similar requirements must be fulfilled.
  • the packing consists of two halves, viz. a lower part 10 and an upper part 12, and of a flap 14.
  • the upper part 12 and the flap 14 are contiguous with the lower part 10 by means of fold lines 16 and 13, respectively, which act as a sort of binge.
  • 20 or seats f r objects such as eggs are provided in the lower part 10 and e.g., as shown, arranged in two rows with five depressions in each row.
  • Each depression 20 is designed to receive one end of an egg.
  • the material has been drawn A number of depressions slightly *back, so that as seen from the uppermost side of the lower part there are produced a notch 22 and between a group of four adjacent notches 22 or egg seats '20 a vertical projection 24.
  • the outermost or end depressions 22' extend to the ends of the lower part and thus interrupt an edge flange 26, which otherwise extends along the circumference of the upper portion of the lower part.
  • the upper part 12 of the packing is designed with an oblique lateral wall 28, which as shown in FIG. 1 has an undulating outline and a flat bottom 30.
  • An edge flange 32 extends along the circumference of the upper part.
  • the flap 14 is composed of an oblique wall 34, which like the lateral wall 28 of the upper part has an undulating outline, andof a plane wall 36, which carries hollow frusto-conically shaped projections 38, the number of and positions of which correspond to the projections or supports 24 on the lower part.
  • each projection enters the space between four adjacent eggs and supports same against movement toward each other.
  • the upper part 12 is swing about the fold line 16 upwardly and inwardly over the flap 14 as well as the lower part into the position shown in FIG. 4, in which the packing is closed.
  • the flat bottom 30 of the upper part rests upon the bases of the projections 38 and is effectively supported against being depressed, as the bottoms of the said projections rest respectively upon the projections 24 on the lower part.
  • Two projections 44 are provided on the oblique wall 34 of the flap 14, which said projections when the packing is being closed engage aperture 46 in the oblique lateral wall 28 of the upper part, which is thereby locked, but an inwardly directed pressure applied to the projections 44' will easily permit it to open again.
  • the invention is independent of the number ofdepressions 20 in the lower part and also of their being disposed'in two or more rows. However, it is required that there must be at least four depressions in two rows, two in each row, so as to allow space for a single supporting projection 38 on the swingable flap 14.
  • the cross section of the supporting projections 38 does not have to be a circular one, as shown, but may e.g. be angular and comprise concave curves corresponding to the rounding of the eggs.
  • the depressions 20 in the lo-werpart may be divided into groups, and correspondingly the upper part may be provided with one or more depressions, dividing its hollow space into two or more parts. This may be expedient when it is desired to divide the closed packing with its contents in two or more parts by cutting it through.
  • a single flap 14 can be used at one end of the lower part or two flaps can be used, one at either end.
  • the latter embodiment for example, can be used in connection with a lower part with six depressions.
  • the invention is not restricted to the undulating outline of the oblique lateral wall of the upper pant, shown in the drawings.
  • a packing for a number of eggs and other fragile or delicate objects including a lower part having two parallel rows of side-by-side individual depressions for the lower portions of the objects, a cup-shaped upper part with a fiat bottom and a surrounding oblique lateral wall 'of undulating outline, and an angularly-shaped flap, said lower part and said upper part being hinged together at one edge of said lower part and said flap being swingably connected by a hinge to said lower part at another edge of said lower part, wherein the improvement comprises a lower part having verticallyextending projections located between the rows of depressions with each projection located centrally of each group of four depressions, said projections having supporting surfaces approximately in the plane of the upper surface of the lower part and a flap structure, which, when the flap is folded inwardly over the lower part, includes an oblique wall extending upwardly from a position adjacent said hinge and a flat wall extending inwardly from the upper part of said oblique wall, said flat wall of the flap having a free projecting edge
  • a packing according to claim 1 in which the oblique wall has an undulating outline conforming to that of the lateral wall of said cup-shaped upper part.
  • a packing accordingto claim -1 in which the oblique wall is tapered inwardly in the direction towards its free edge.
