Definitions

  • the present invention relates to a container for loose foodstuffs, particularly eggs.
  • egg containers those containers are meant for packaging normal size eggs, usually, as is known, six eggs, for the commercialization of the eggs themselves. They provide a traylet having a series of housings, one for each egg, the housings being separated by diaphragms that avoid the reciprocal collision of the eggs.
  • two rows are dealt with put side by side, each one with three egg places.
  • a lid goes to close itself, hinged by a long side of its rectangular perimeter.
  • the girdle line of the egg container that is the rim of the traylet whereagainst the lid goes to abut when closing itself, finds itself at half the height of the eggs, arranged vertically with their tips turned upwards.
  • the closing of the egg container is deputed to a system represented by protuberances of the plastics layer on the rim of the traylet that go to snappingly engage themselves in corresponding recesses of the plastics layer on the rim of the lid.
  • the wall of the traylet presents hooking assemblies intended to engage themselves in corresponding cuts on the wall of the lid when this one closes itself onto the traylet itself.
  • a critical feature of egg containers is their aptitude to be stacked - or, more generally, to support loads of a certain magnitude anyhow applied on their lid - without damage.
  • a type of egg container presents cone frustum protuberances of the bottom of the traylet up to the level of the closing of the upper flat bottom of the lid, here making up a reaction constraint element to the loads that go to burden thereupon.
  • the present invention takes the steps from the consideration that no one of the presently known egg containers turns out to be satisfying in connection with the closing system and with the resistance to the loads impressed on the lid.
  • the egg containers of the state of the art are not so satisfying neither from the viewpoint of the packaging of eggs, nor of their performance during transportation, distribution and storing.
  • the packages In the stacking, for transportation and storing of the product, the packages do not bear the load of the packages arranged thereon and many eggs are so destroyed.
  • the object of the present invention is to satisfy such an exigency.
  • Such an end is achieved according to the teaching of the present invention by providing the formation of partition septa among the egg places in the traylet.
  • the profile of such septa is brought to occupy all the inner encumbrance of the lid in the closed position thereof on the traylet.
  • such septa are provided with a deviation of the profile thereof on the portion that is turned onto the sides of the egg container whereupon the lid is not hinged, but goes, on the contrary, to close itself, from rectilinearity into a sawtooth recess making up a unidirectional hooking means turned toward the traylet, that is to say such as to be engaged by a complementary means in the closing sense of the lid onto the traylet and to offer resistance to the disengagement in the opposite sense, of the opening of the lid.
  • the lid is endowed with corresponding reliefs so shaped as to be fit for hookingly engaging themselves with said recesses.
  • septa perform the double function of a closing system and of a reaction constraint means against the loads on the lid during the lifetime of the package.
  • the closing system made up of the hooking means offered by the recesses of the septa and the reliefs of the lid is simple and reliable: the resistance to the closing is very low, and on the contrary the resistance is considerable to the opening by the forces tangential to the side wall of the egg container that can be encountered by the egg container itself during its lifetime.
  • the resistance to the opening will be, however, a minimum against forces applied perpendicularly or almost perpendicularly to the wall of the egg container, whereby it will be very easy for the end consumer to open the same without effort.
  • the egg container according to the present invention is not responsive to the direction errors of the closing of the lid by an automatic machine, because the septa make up a structure that inherently guides the lid in its closing onto the traylet according to a correct movement.
  • the subject of the present invention is a container for loose foodstuffs, particularly eggs, comprising a traylet fit for containing eggs in an ordered rectangular arrangement of as many respective containing places, and a concave lid, intended in its closing onto the traylet, to turn its concavity towards the latter, wherein said ordered rectangular arrangement of egg places is defined by partition septa crossed with each other, the profile whereof extends to occupy all the inner encumbrance of said concavity of said lid in the closed position of the same onto the traylet.
  • the egg container of the present invention comprises a traylet 1 for containing eggs, and a lid 2, hinged on a long side of the traylet. It is here exemplified the usual case od a traylet for six eggs, with a matrix, or ordered rectangular arrangement, of 2x3 places for as many respective eggs, 4, 4a, 4b, 4c, 4d, 4e.
  • such places are separated by three crossed partition septa, one longitudinal, two transversal, that individuate the rectangular matrix of places, which crossing with each other mutually partition themselves in flaps 3, 3a and 3b, 3c for the transverse septa and 5, 5a, 5b for the longitudinal septum, individuating and partitioning contiguous places.
  • the lid 2 presents a deep concavity turned towards the traylet.
  • the septa above extend to occupy all the inner encumbrance of such a concavity with the lid closed, as shown in FIGURE 2.
  • said septa are upperly endowed with unloading recesses, arriving upwards up to the inner level of the lid, in the closed position thereof, only in correspondence with the side parts and of the central part of their profile.
