Definitions

  • the present invention relates to a packaging tray for eggs, which has an application in the food product packaging industry, and more specifically in the area of packages for transporting and marketing eggs.
  • the half-tray which is made of molded pulp, continues to offer optimal shock-absorbing performance for the delicate egg transport and storage operations, while at the same time it is strong enough so that the half-tray does not sustain excessive deformations that may damage the product, while being lightweight and inexpensive, in addition to the fact that given its composition, pulp can act due to simple gravity as an egg content absorbing element in the event that any of the units contained in the packaging were to accidentally break, such that in said situation, the remaining eggs packaged in the tray would not be affected, being able to be transferred in such case to another package at the point of sale itself, prior to being marketed.
  • the bottom part made of pulp is usually manufactured by means of jointly molding two half-trays attached through a linkage.
  • Each half-tray usually comprises a dozen cavities, and the two half-trays are symmetrical with respect to an axis coinciding with the linkage.
  • the two half-trays are subsequently separated to be used independently.
  • the process of loading eggs in the trays is automatic, such that the trays are taken from a feeder on a conveyor belt to a loading area, the eggs are automatically deposited in the corresponding cavities of the tray and then, once it is filled, each tray is covered with the plastic lid or with another tray made of pulp. Once covered, the tray loaded with eggs formed by two half-trays attached through the linkage goes to the separation area, where the two half-trays are separated manually or automatically. At this point of the process there are different options, as explained below.
  • the linkage normally incorporates means to facilitate cutting it, such as a perforated or weakening line, for which reason the linkage is also referred to as the precut area.
  • the present invention relates to a packaging tray for eggs, which allows overcoming the problems of the state of the art, allowing manufacturers to avoid the drawbacks that result from having to have all three types of trays, as the tray of the invention allows a clean and easy separation of the half-trays by any of the manual or automatic methods, while at the same time preventing the trays from bending excessively along the linkage when they are stacked in the separation machine, also referred to as denester.
  • the tray proposed by the invention comprises two half-trays made of pulp obtained by means of molding, so said half-trays are obtained such that they are attached through a linkage, which is also made of molded pulp.
  • Each half-tray comprises a plurality of cavities for partially housing eggs.
  • the linkage comprises a precut area, which is usually a straight line, in turn comprising at least one perforation, as described in the preceding section, to facilitate separation of the half-trays.
  • the tray comprises at least one pair of projections made of molded pulp separated from one another and located in a facing manner in the linkage, each projection of the pair being located in a half-tray, such that when the half-trays are bent along the linkage, given the separation existing between the pair of projections, which is preferably equivalent to the width of the cuts of the perforation, contact occurs between the upper ends of the projections.
  • This achieves a dual effect, i.e., on one hand it prevents the tray from continuing to bend in the absence of a force in addition to the weight itself of the tray or trays in the stacked position, given that contact of the upper ends of the projections functions like a stop to prevent the tray from continuing to bend.
  • the projections may have different geometries, provided that they are located in the perforated line and are separated from one another. Therefore, when an operator is going to manually separate the half-trays, when such half trays are bent downwards, the projections touch at their ends, and when one half is pushed against the other half, the projections apply a force against one another, such that they act like a lever so that the tray can be separated in a quick and easy manner without being torn or damaged.
  • the projections serve so that when the trays are stacked in the denester, the projections abut against one another, such that it prevents the tray from curving excessively.
  • the tray of the invention offers a simple solution to the two problems described above given that it serves for any of the separation methods described above and solves the drawback of curving in the tray loading area, given that it has the same thickness and therefore the same strength throughout the entire surface and in turn incorporates means to facilitate manual separation of the two half-trays when there are no automatic cutting means in the installation. Uniform and precise separation lines are obtained as a result of the means provided to facilitate separation of the two half-trays.
  • the packaging tray for eggs proposed by the invention comprises two half-trays (1) made of pulp obtained by means of molding which are attached through a linkage (2), which is likewise made of molded pulp.
  • Each half-tray (1) comprises 12 cavities (4) for partially housing eggs. This format is referred to as 2 x 12 (2 half-trays (1) with 12 cavities (4) each).
  • the linkage (2) comprises a precut area (3) in turn comprising a perforation.
  • the tray also comprises two pairs of projections (5) made of molded pulp separated from one another and located in a facing manner in the linkage (2).
  • Each projection (5) of the pair is located in a half-tray (1), such that when the half-trays (1) are bent along the linkage (2), given the separation existing between the pair of projections (5), which is preferably equivalent to the width of the cuts of the perforation, contact occurs between the upper ends (5') of the projections (5).
  • the cavities (4) have a concave part located in an inner face of the tray, whereas the projections (5) extend substantially perpendicular to an outer face of the tray, opposite the inner face.
  • the precut area (3) comprises a through-and-through perforation the cuts of which go through the linkage (2), which facilitates separation.
  • the packaging tray for eggs is rectangular and comprises two rectangular and symmetrical half-trays (1) with respect to the linkage (2), each of which comprises 12 cavities (4), the four corners thereof being rounded.
