Definitions

  • the present invention relates to the packaging of eggs and, more particularly, to an improved egg package and method of making same.
  • eggs are shipped in crates or cartons containing several dozen eggs nested in compartments or positioned upon so-called flats which, like the usual egg spacer, is composed of a liquid-absorbing brous material.
  • raw eggs are commonly retailed in paper, papier-mch or cardboard containers formed with removable compartments or individual recesses adapted to receive the eggs.
  • the packaging material is, for the most part, opaque, thereby preventing complete and ready inspection of the contents of the package. This is particularly important since eggs are notoriously fragile and tend to crack in shipping. It has thus been necessary, in instances where complete inspection is not economical, to assume a certain proportion of cracks, thereby reducing the selling price.
  • the packaging materials are readily deformed by the application of even moderate forces during normal handling thus forcing portions of the carton wall into such contact with the shell that cracking of the latter results.
  • Another disadvantage 'of earlier techniques resides in the fact that paper-based packaging materials are liquidabsorptive so that the contents of a cracked egg which leaks from the shell is drawn into the interstices of the packaging material, simultaneously preventing recovery of the egg and rendering the packaging material unfit for reuse.
  • a further disadvantage derives from the fact that many types of egg cartons are incapable of withstanding the compressive stresses that arises from stacking of the containers so that, in most instances, the eggs themselves ymust withstand these forces. This factor prevents stacking of eggs to any substantial height and, therfore, results in a requirement for greater storage area.
  • an egg package consisting of an upper and a lower foil member of a substantially huid-impermeable resilient sheet material formed with respective corresponding arrays of spaced cups registering with and open in the direction of corresponding cups of the other member in a juxtaposed position of the two members in which the cups extend outwardly from a median plane at the interface.
  • the toil members have marginal portions in surface contact along the periphery of each array so that the corresponding cups of the two members form an enclosure for the egg capable of Patented Fein. 8, i366 ICC retaining for prolonged periods even the liquid contents thereof should cracking occur.
  • the cups of the upper member are shaped generally to conform to the configuration of the broader end of the egg while those of the lower member conform generally to the narrower end.
  • the respective arrays of cups extend substantially longitudinally and may be orthogonally aligned so that package can receive six, ten or twelve eggs as the case may be. It must be pointed out, however, that the method described in conjunction with this invention is equally applicable to the packaging of greater or fewer numbers of eggs.
  • substantially and relatively liquid-impermeable foil may be employed in connection with the invention, it is preferred to make use of a sheet material which is transparent as well as tough but yet can be easily shaped into the desired configuration.
  • synthetic resin foils e.g. of hard polyvinylchloride etc.
  • metal foils e.g. aluminum foil
  • substrate porvided with a metallic layer e.g. aluminum foil
  • the metal should, of course, be inert to the liquid contents of the egg.
  • the synthetic resin sheet material When the synthetic resin sheet material is employed, it may be of the thermally fusible type to enable heat sealing of the periphery of the package to produce a substantially totally enclosed unit.
  • the storage of eggs requires ventillation of the egg compartments to permit the air sac in the broad portion of the egg to breathe and to allow the escape of gases.
  • at least one of the foil members is provided with a channel communicating with the respective cups and open to the atmosphere. Further channels may be provided in one or both of the members to interconnect the compartments for facilitating the circulation of air therethrough.
  • corrugations in the walls of the cups to reinforce the latter against axial compressive forces of the type involved in the stacking of the egg packages.
  • These corrugations may lie along axial planes of each cup and be angularly spaced about the axis thereof while extending perpendicularly to the interface.
  • the corrugations also increase the resilience of the enveloping wall of the cup so that lateral shock is, to a certain extent, taken up by the elastic packaging material.
  • the corrugations may form ribs extending into the interior of each cup to reinforce the latter in the usual manner against compressive forces having components in the direction of the ribs.
  • the latter may also serve, in part, for holding the eggs away from substantial engagement with the cup wall whereby indentation of the latter as a consequence of handling cannot result in egg breaking.
  • These ribs which may extend radially into the interior of the cup to a distance of l or 2 mm. also serve to center the egg and prevent repeated jostling of the latter against the cup wall. It has been found that these ribs play another significant role in the egg package in that they space the egg away from the wall to permit passage of air toward the upper and upper part of another in a stacked condition without.
  • the cups of at least one of the foil members are formed with seating means such as an annular seating surface for the eggs.
  • This seating surface in peripheral engagement with the egg, serves to center the latter and to hold it out of engagement with the upper and lower portions of the.y
  • FIG. 1 is a fragmentary plan view of a foil provided with cups, in accordance with the invention, prior to completion of the package;
  • FIG; 2 is a fragmentary perspective view of the comv pleted package;
  • Y FIG. 3 is a cross-sectional View taken generally along line III-III of FIG. 2;
  • FIG. 4 is a cross-sectional view taken generally along the line IV--IV .of FIG. 2;
  • FIG. -5 is a cross-sectional view similar to FIG. 4 butv Cups 16 and 18 form two 10 parallel to the arrays and open at the common surface Vof the foil while extending codirectionally therefrom.
  • Median line 10 bisects the foil into two halves or members one of which is adapted to overlie the other upon folding of the foil along the line 1t).
  • a plurality of angularly spaced radial ribs 36 lie generally along generatrices of the axially symmetrical cups 16 and 18, the former of which are shaped to receive the broad end of an egg while the latter have ,a configuration correspond-V ing to that of the narrower or pointed end of the egg;
  • These ribs 36 are constituted by corrugations in the wall ofthe cups which reinforce the latter against axial force and simultaneously increase itsv resilience while spacing the egg therefrom.
  • the cups 16 and 18 of each array are interconnected by channels 28 of the generally rectangular cross-section which register with those of the other member to form a .Y
  • Main channels 26 extend, however; to the periphery of each array and, therefore, to the median line 10' in order to permit entry of air into the compartments'when the unit is sealed along its peripheral edges 50. To open the channels 26 at their junction :with
  • this junction is incised at 30.
  • the maximum depth to which the ribs'36 extend into the compartment is'indicated at 38 and may be from l-2 mm, as previously mentioned.
  • An egg 17 is indicated in solid linesto show its relation to the cups; It should be noted that an upward bulge or built-up portion 32 is provided at 'therlower endof the Vlower cup to form a seating surface for the narrow end of the egg, thereby centering it generally out of contact with the major wall portions of the cups, It Should be noted.
  • FIG. 5 I show'a similar arrangement wherein the ribs 36of the upper'and lowercups 16 and 18l extend parallel to the axis of symmetry of the cups, the upper cups being formed with an indentation 46 vforming a seat for the broader end of the largest size eggs to be yreceived in the'cup.
  • The: cups of both embodiments are formed along the upper portions 44, 44 with domed parts out of engagement with the. egg which are complementarily receivable within'concavities 42, 42 in generally/cylindrical lower parts 40, 40tof the bottom cups.
