Definitions

  • the present invention relates to egg boxes of the type comprising on the one hand a body open upwards on which protrude downwards at least two longitudinal rows of converging cells and upwards of the pins, and on the other hand a cover fixed on this body and supported by the pins.
  • the body is made of plastic, in particular transparent material, consisting of a flat sheet of generally rectangular shape on which are formed projecting downwards at least the two longitudinal rows of convergent cells open towards the top, and up, central pins open down and located between these two rows, as well as side pins open down and located along each longitudinal edge of the sheet, in line with the central pins.
  • the cover is made from a rectangle cut from a strip of flat cardboard previously printed. This flat cardboard cover has two side wings which, after folding, are fixed by gluing to the side parts of the body.
  • the conditioner is obliged to identify the boxes filled with eggs as soon as this operation, 'has not always the corresponding command which often arrives at the last minute.
  • the conditioner does not want to stop the packaging line, he is obliged to supply certain lanes with temporary boxes or trays which will be reconditioned later.
  • the cardboard cover does not allow customers, at the time of purchase, to have an overview of all the eggs contained in the box so as to check whether they have been damaged during transport between the packaging unit and the point of sale.
  • EP-A-0 006 043 discloses an egg carton according to the preamble of claim 1 comprising on the one hand a body formed by thermoforming from a flat sheet of plastic material, in particular transparent material on which protrude from the cells and pins and on the other hand a hollow-shaped cover supported by the lateral pins.
  • This box further comprises means for closing the cover on the body and tamper-evident means.
  • the present invention therefore relates to an egg box of the type mentioned above and characterized in that the tamper-evident means consist of small studs formed on the external faces of the lateral pins provided on the longitudinal edge of the body at l 'opposite of the cover, by small holes provided on the front wall of the cover into which the small nipples penetrate when the cover is closed on the body and by a guarantee adhesive strip applying at the same time on the small nipples and on the external face of the front wall to secure the cover and the body between them and in that the entire body and said cover are produced by thermoforming in a single operation.
  • the tamper-evident means consist of small studs formed on the external faces of the lateral pins provided on the longitudinal edge of the body at l 'opposite of the cover, by small holes provided on the front wall of the cover into which the small nipples penetrate when the cover is closed on the body and by a guarantee adhesive strip applying at the same time on the small nipples and on the external
  • the egg carton shown in Figs. 1 and 2 is produced by thermoforming in a single operation from a rectangular flat sheet 1 of transparent plastic, for example PVC or polystyrene.
  • the body 2 has twelve cells 4, each having the general shape of a straight pyramid trunk with a regular ortogonal base. Each cell 4 is connected to the sheet 1 by a vertical wall 5 of low height which extends it upwards.
  • the cells 4 are distributed symmetrically with respect to a longitudinal plane of symmetry P of the box, in two rows of six.
  • This plane P is also a plane of symmetry for several elements projecting upwards. These projecting elements are formed by lateral pins 6a, 6b, 6c, distributed over the longitudinal edges 7a, 7b, and lateral 8 between two adjacent cells 4 and by pins of ends 9, of smaller dimension, arranged at the four body corners 2.
  • the lateral pins 6a, 6b, 6c have the shape of pyramids with a triangular base converging upwards and a height substantially equal to the height of the cover 3.
  • the large base of said pins consists of an edge of the sheet. 1 and by one side of the two adjacent cells 4.
  • the end pins 9 also have the shape of triangular pyramids converging upwards.
  • the large base of the pins 9 is formed by a lateral edge and a longitudinal edge of the sheet 1 and by a side of a socket 4.
  • the outer faces of the lateral pins 6a, 6b, 6c and the end pins 9 define four inclined planes on which the cover 3 rests, as will be seen later.
  • each lateral pin 6b disposed on the longitudinal edge 7b of the body 2, that is to say opposite the cover 3, is formed a small cylindrical stud 11 projecting.
  • the longitudinal edge 7b has a cutout 14 whose length corresponds substantially to the length of the side of the external face of the pin 6b located in this plane of symmetry.
  • small cylinders 13 with a vertical axis which serve, inter alia, to maintain a certain spacing between the boxes when they are stacked open before the conditioning operation.
  • the cover 3 is produced at the same time as the body 2 from the same flat sheet of transparent plastic.
  • the cover 3 has longitudinal edges 15a, 15b, and side edges 16.
  • a cavity is formed comprising a rectangular top 20, two trapezoidal side walls 21, 22, a rear trapezoidal wall 23 and a front trapezoidal wall 24.
  • These trapezoidal walls define four inclined planes which correspond to the four inclined planes formed by the pins 6a, 6b, 6c and 9, and have a height substantially equal to that of the cells 4 and to that of the pins 6a , 6b, 6c.
  • balusters 25 have the shape of straight pyramid trunks converging upwards and a height substantially equal to the height of the trapezoidal walls of the cover 3.
  • small cylindrical recesses 26 which correspond substantially to the small cylinders 13 produced on the pads 12 of the body 2.
  • the front trapezoidal wall 24 of the cover 3 has small holes 27 which are drilled in the same transverse plane as each small stud 11 which are provided on the external face of the lateral pins 6b and at a distance from the longitudinal edge 15a of the cover 3 corresponding to the distance between the small pins 11 and the longitudinal edge 7b of the body 2.
  • the longitudinal edge 15a comprises a locking pawl 30 produced during the thermoforming operation.
  • Fig. 3 the cover 3 is shown folded over the body 2 shown diagrammatically in dashed lines in order to facilitate understanding of the drawing.
  • the locking pawl 30 is formed on the one hand by a tongue 31 of triangular shape which projects beyond the longitudinal edge 15a and on the other hand by an elastic inner flap 32.
  • the zone of the front wall 24, in the extension of the pawl 30 is cut through an opening 33 to allow the passage, at the time of closing the box, of the small stud 11 located in the plane Q, and to form the inner flap 32.
  • the sheet 1 is provided, between the body 2 and the cover 3, with a longitudinal fold line 29.
  • the small cylindrical pins 11 of the pins 6b penetrate into the orifices 27 provided on the front wall 24 of the cover 3. At this time, the filled and closed boxes can be handled and stored at the conditioner pending their identification. and the installation of a tamper-evident band.
  • an adhesive strip of guarantee 40 bearing different indications is affixed to the external face of the front wall 24 of the cover 3.
  • This adhesive strip 40 is applied at the same time to the pins 11 and to the wall 24 of the cover 3, which makes it possible to increase the rigidity of the box by bringing the cover and body into close contact, while constituting means inviolability to check if the box has not been previously opened.
  • the egg carton thus produced offers many advantages. First of all, making the entire box from a single sheet of plastic material avoids any bonding operation between the cover and the box. In addition, the use of a transparent plastic material for the lid and the body, allows to have an overview and instantaneous of the contents of the box, which undeniably constitutes a selling point. Finally, the cover can serve as a support for the adhesive strips carrying a lot of information, this marking operation being able to be carried out at the last at the conditioner, depending on the orders recorded.
