  • the invention provides a container for fresh produce, wherein the container comprises:
  • a tray which comprises a bottom wall, a circumferential outside wall and an open top for insertion and removal of the fresh produce, wherein the tray has a first bottom-passageway through said bottom wall;

  • the container has a closed condition in which the lid is covering said open top, and an open condition in which the lid is removed from said open top for insertion and removal of the fresh produce, and
  • the lid has a first lid-passageway through the lid
  • an interior container space for containing the fresh produce said interior container space being defined by at least said bottom wall, said circumferential outside wall and said ventilation shaft;
  • an elevated carrying platform for carrying the fresh produce wherein: - the elevated carrying platform is located at an elevated level relative to the bottom wall,
  • the elevated carrying platform is dividing the interior container space into an interior ventilation space and an interior storage space, the interior ventilation space being located in-between the bottom wall and the elevated carrying platform,
  • the ventilation shaft is extending with its longitudinal shaft direction from at least said elevated carrying platform in the direction of said open top, which corresponds to the direction of said second shaft end of the ventilation shaft, and

  • the container according to the invention is a tray-based container, which, as explained above, is suitable for preventing bruising of packed vulnerable products.
  • the abovementioned ventilation shaft, and the abovementioned in-line fluid-flow communication and sideways fluid-flow communication that it offers allow the packed products to be reliably ventilated at all times, also when the packings are stacked onto one another.

  • a controlled distance is provided in-between the products in the container and a surface on which the bottom wall of the container is resting.
  • This controlled distance in the form of said interior ventilation space, provides for a controlled ventilation underneath the products.
  • the ventilation shaft provides synergistic effects regarding said controlled ventilation underneath the products, since the interior ventilation space of its own would normally be prone to forming a dead-flow area underneath the products. That is, the ventilation shaft provides for a very effective air- draught, which prevents the occurrences of such dead-flow areas.
  • the container further comprises:
  • said sideways fluid-flow communication is realized at least via a sideways fluid-flow path, which provides fluid-flow communication between said interior shaft space of the container and an exterior environment of the container, said exterior environment being located on a side of the circumferential outside wall of the container facing away from the ventilation shaft, in that said sideways fluid-flow path is at least partly extending:
  • the elevated carrying platform functions as a distribution platform for the ventilation flow along the sideways fluid-flow path. This distribution platform allows the produce in the interior container space to receive an evenly distributed ventilation flow.
  • the lid has a first circumferential abutment portion, extending in circumferential direction around said longitudinal shaft direction
  • the ventilation shaft has a second circumferential abutment portion, extending in circumferential direction around said longitudinal shaft direction, and wherein, as seen in said stacked condition, said first circumferential abutment portion of the lid and said second circumferential abutment portion of the ventilation shaft are lying against one another.
  • the circumferential shaft wall has no passageway therethrough.
  • the invention is furthermore embodied in a method of ventilating a stack of containers according to any one of the abovementioned
  • the method comprises controlling a gas to flow at least along the corresponding longitudinal shaft directions through the corresponding interior shaft spaces of the corresponding ventilation shafts of the containers of the stack.

  • Fig. 2 separately shows the tray of the container of Fig. 1 in a perspective view at the bottom side of the tray.
  • Fig. 3 shows a cross-section through the abovementioned "stack of containers in a stacked condition", based on two identical ones of the container of Fig. 1, and wherein the shown cross-section is a vertical cross- section according to a mid-plane through the stack of containers, which mid- plane is indicated by arrows III in Fig. 1.
  • the container 1 of Fig. 1 is the same as the upper container 1 as shown in Fig. 3.
  • the lower container 1A as shown in Fig. 3 is, as mentioned above, identical to the upper container 1.
  • all parts and aspects relating to the lower container 1A which are alike to the parts and aspects relating to the upper container 1 have been indicated in Fig. 3 by the same reference numeral, but with the suffix "A" appended thereto.

  • controllingly forcing a fluid to flow in upwards direction through the interior shaft spaces of the ventilation shafts of stacked containers may generally involve that the first lid-passageway 41 of the lid of the uppermost container in the stack, may optionally be closed off to a more or lesser extent, to thereby control the ratio of the extent of the sideways fluid-flow communication relative to the extent of the in-line fluid-flow communication.

  • Fig. 3 it is furthermore seen that the first circumferential abutment portion 91 of the lid 4 and the second circumferential abutment portion 92 of the ventilation shaft 7 are lying against one another. As mentioned, this promotes that fresh ventilation flow and used ventilation flow through a stack of containers remain separated from one another.
  • This can be understood when thinking of an imaginary different situation in which in Fig. 3 the first circumferential abutment portion 91 of the lid 4 and the second circumferential abutment portion 92 of the ventilation shaft 7 would not lie against one another, but would instead be spaced from one another.
  • the used sideways ventilation flow could be sucked, via the imagined inter-space in-between the portions 91 and 92, from the interior storage space 10 into the interior shaft space 30.
  • Such a suction would be due to pressure difference between the sideways ventilation flow and the in-line ventilation flow, and this would result into an undesirable mixing of the used sideways ventilation flow with the in-line ventilation flow, which should preferably remain as fresh as possible.
  • the circumferential shaft wall 9 has no passageway therethrough, in order to further promote that fresh ventilation flow and used ventilation flow through a stack of containers remain separated from one another.
  • the shown lid of the shown container is fully detachable relative to the shown tray.
  • the lid of a container according to the invention may for example also be fixedly connected to the tray, for example by means of a hinging mechanism, such as e.g. a living hinge.
  • the ventilation shaft of a container according to the invention may be manufactured as an integral part of the elevated carrying platform, but the ventilation shaft may also be manufactured separately from the elevated carrying platform.
  • elevated carrying platform may be manufactured by thermoforming, while the ventilation shaft is separately manufactured by injection moulding, whereafter the elevated carrying platform and the ventilation shaft may be (fixedly or detachably) connected to one another.
  • Ventilation fluids such as for example (cooling) air, but also various other fluids, such as for example (fruit) ripening gasses, e.g. ethylene.
  • a single container according to the invention may comprise more than one ventilation shafts of the discussed type, the respective ventilation shafts being connected at mutually different locations, respectively, to the elevated carrying platform of the container.

Abstract

Selon l'invention, un récipient (1) pour produits frais comprend un plateau (2), un couvercle (4), une plateforme de transport élevée (3), et un puits de ventilation (7). Le puits de ventilation s'étend à partir de la plateforme de transport élevée dans la direction de la partie supérieure ouverte du plateau. De multiples récipients de ce type sont empilables les uns sur les autres pour former une pile de récipients. Lorsqu'ils sont empilés, les espaces de puits intérieurs des puits de ventilation des récipients empilés sont en communication d'écoulement fluidique en ligne les uns avec les autres le long des directions de puits longitudinales, tout en étant en communication fluidique latérale avec les espaces de récipient intérieurs. L'invention permet un flux de ventilation hautement efficace qui s'étend à travers une pile de récipients, plus ou moins similaire à un tirant d'air de type cheminée.
