Definitions

  • the present invention relates to a nestable tray made of cardboard sheet material comprising side walls and a bottom.
  • It also relates to a blank for the constitution of such a tray, a package comprising product webs manufactured with such a blank and a machine for forming such a tray.
  • Packaging is also known, for example for cheeses or yoghurt pots, stackable on top of one another so as to constitute stackable piles on a pallet.
  • Such batteries must firstly allow the lower packs to withstand the compression of the packages of the top and secondly be fairly stable vertically to avoid tilting laterally. To do this it is generally provided corrugated material sufficiently resistant to compression with splines arranged vertically, and stacking lugs with corresponding recesses, the weight of a package from above then resting on the walls of the package below.
  • the resistance of the material is then sufficient to allow the packaging to be grasped for example by means of recessed handles in two lateral faces facing the plate.
  • the weight of the carton of the packaging is indeed and for example necessarily greater than of the order of 400g / m 2 and in all cases greater than 350g / m 2 for reasons of strength of the materials, especially concerning the strength of the grip handles. This is particularly the case for the boxes described in the documents CH 670-433 or EP 0 767 103 , describing trays comprising four side walls and a bottom, at least two opposite walls each having a flap provided with a longitudinal reinforcement flap.
  • the present invention aims to provide a tray, a blank, a packaging and a machine for forming such a tray, better than those previously known to the requirements of the practice, in particular in that it makes it possible to overcome these drawbacks by minimizing the weight of the board and this while stiffening the board in its length and by allowing the presence of strong gripping handles, easy to grasp for a user.
  • the invention also allows the packets to be embedded in each other and / or a stack height which may be adjusted to the products with a distribution of the load on all the products.
  • the bevel formation of the bottom of the plate unexpectedly strengthens the rigidity of the plate during side impacts, which is particularly advantageous during the conveying and handling of packages.
  • the present invention proposes in particular a plate made of cardboard sheet material comprising a bottom and four side walls, two opposite side walls each comprising a flap provided with a longitudinal flap intended to form a rim extending over the entire length.
  • said component and acting as a beam of bracing between the two other opposite side walls characterized in that the rim extends over part of the height of said flap in that the tray is mechanically formed, in that the basis weight of the board is less than or equal to 350 g / m2, and in that said opposite side walls are respectively provided with at least one recess allowing the user to enter it below said rim.
  • the tray thus obtained has excellent torsional strength despite its light basis weight.
  • the hand and / or one or more fingers of the user will therefore be able to grip a reinforced portion of cardboard particularly solid at the edge of the ridge and despite a low weight paperboard, while allowing, in a particular embodiment, a excellent stacking trays by nesting into each other.
  • the bottom thus has a beveled shape transversely and longitudinally.
  • the invention also proposes blanks for forming the trays as described above. It also proposes a blank for the mechanical constitution of a plate, comprising a rectangular central panel provided on each side with a flap, namely two opposite first flaps and two opposite rectangular or substantially rectangular second flaps, said second flaps being respectively opposite.
  • first flaps each having a longitudinal flap adapted to be folded towards the inside of the tray to form a flanging said flap extending over the entire length of said flap, the rim being adapted to play a role of bracing beam between the two second flaps when the plate is formed, characterized in that the longitudinal flap extends on one face of said corresponding first flap and is adapted to be fixed by gluing on part of the height of said flap, in that the grammage of the carton is less than or equal to at 350g / m2, and in that said flaps are also respectively provided with at least one obviously forming a handle located below said rim once the latter achieved.
  • each flap is connected to the central panel by a strip connected respectively on either side of the strip to said flap and to the central panel by parallel fold lines, the lateral edges of the strip extending obliquely outwardly. compared to the central panel.
  • first fold lines are connected to the central panel by the free edge of an intermediate band, said free edge being at an angle to the edges of the bottom of the plate.
  • the lateral edges of the intermediate strips are angled with respect to the fold lines, on a first portion located on the side of the central panel so as to give the bottom of the tray a partial frustoconical section in the transverse and longitudinal directions of the tray , the walls then being vertical again.
  • the first fold lines are at an angle to the edges of the bottom of the plate and / or the lateral edges of the first flaps are oblique with respect to the fold lines, so as to give the plate a section of frustoconical shape in the direction transverse and / or longitudinal.
  • the small base of the first flaps is on the side of the central panel.
  • At least a portion of the periphery of the second flaps and / or the first flaps comprises a protrusion promoting the embedding and / or forming a clean nipple to cooperate with a recess in the bottom of the tray at the edge and / or notch on the lower peripheral edge of the end flaps.
  • the invention also proposes a package comprising a tray of the type described above, characterized in that it comprises at least one sheet of at least two rows of containers connected together by their upper parts, the respective dimensions of the containers. and the tray being such that the upper layer of containers is adapted to support the weight of the top tray via or not an interposed intermediate plate, for example and advantageously due to the possible partial embedding between trays.
