Definitions

  • the invention relates to 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.
  • Containers based on such a tray which is a relatively flat device, are often used for storing certain types of small vegetables or fruits.
  • these kinds of products are not suitable to be directly stacked onto one another in more than one or only a few layers. If stacked (too high) onto one another, these products may easily get bruised by mutual product pressure and/or may easily receive too little ventilation, which will shorten their shelf life considerably.
  • flat tray-based containers are often used for these kinds of products, wherein every container contains only one or only a few layers of the products, and wherein the containers are stacked onto one another.
  • the present invention provides a container according to the appended independent claim 1.
  • Preferable embodiments of the invention are provided by the appended dependent claims 2-12.
  • the invention provides a container for fresh produce, wherein the container comprises:
  • 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.
  • the invention provides for a highly effective ventilation flow, which is extending through a stack of containers, more or less similar to a chimney-like air-draught.
  • the container further comprises at least one shaft-wall-passageway through said circumferential shaft wall for realizing said sideways fluid-flow communication.
  • said sideways fluid-flow communication of the container is realized at least via a first fluid-flow path, which is at least partly extending between a first circumferential bordering edge of the first lid-passageway and a second circumferential bordering edge of the second shaft end.
  • said sideways fluid-flow communication is realized at least via a second fluid-flow path, which, as seen in said stacked condition, is at least partly extending between the bottom wall of said upper container of the stack and the lid of said lower container of the stack.
  • said second fluid-flow path is extending from said interior shaft spaces of said upper container and said lower container to an exterior environment of the stack of containers, said exterior environment being located on a side of the circumferential outside walls of said upper container and said lower container, which side is facing away from said ventilation shafts.
  • the container further comprises at least one second bottom-passageway through the bottom wall of the container, said second bottom-passageway not being enveloped by said transverse circumferential cross-section.
  • the container further comprises at least one second lid-passageway through the lid of the container.
  • the container further comprises at least one outside-wall-passageway through the circumferential outside wall of the container.
  • the container further comprises:
  • the elevated carrying platform has a first platform-passageway through the elevated carrying platform, wherein the ventilation shaft is extending through the first platform-passageway.
  • the container further comprises at least one second platform-passageway through the elevated carrying platform of the container.
  • 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.
  • said interior ventilation space contains a liquid absorbing material.
  • the liquid absorbing material may for example be a liquid absorbing pad lying at the bottom of the interior ventilation space.
  • the liquid absorbing material is suitable for absorbing liquids dripping off from the products, while at the same time the elevated carrying platform separates the products from lying directly on top of the wet absorbing material.
  • the tray 2 and the lid 4 are made from plastic, wherein the ventilation shaft 7 has been manufactured as an integral part of the tray 2.
  • the elevated carrying platform 3 is made from cardboard.
  • FIGs. 1 and 2 foot parts 18 of the bottom wall 5, as well as elevated parts 19 of the bottom wall 5 are shown.
  • the foot parts 18 of the upper container 1 are resting on the lid 4A of the lower container 1A.
  • the foot parts 18, however, are of course not visible in Fig. 3 , since the cross-section of Fig. 3 is according to the mid-plane III of Fig. 1 , which mid-plane does not have the foot parts 18.
  • Fig. 3 schematically shows the additional passageways 61 and 71, as well as some further optional locations for the passageways 52.
  • the various shown two-way arrows are indicating various fluid-flow communications or fluid-flow paths through the various passageways, spaces, inter-spaces, or the like.
  • the two-way arrows indicating the first fluid-flow path and the second fluid-flow path have been specifically indicated by the reference numerals 81 and 82, respectively, as mentioned above.
  • the second fluid-flow path 82 is extending between the lid 4A of lower container 1A and elevated parts 19 (see Fig. 2 ) of the bottom wall 5 of the upper container 1.
  • the lower container 1A has been shown to contain the abovementioned liquid absorbing material 15, while the upper container 1 has been shown without the liquid absorbing material.
  • 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 (bottom wall of the) tray, but the ventilation shaft may also be manufactured separately from the (bottom wall of the) tray.
  • the tray may be manufactured by thermoforming, while the ventilation shaft is separately manufactured by injection moulding, whereafter the tray and the ventilation shaft may be (fixedly or detachably) connected to one another.
  • Separately manufacturing the ventilation shaft by injection moulding, instead of by thermoforming provides additional freedom for designing the ventilation shaft, such as for designing the abovementioned at least one shaft-wall-passageway through the circumferential shaft wall of the ventilation shaft.
  • 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 bottom wall of the tray.
  • a single other unit may fulfill the functions of several items recited in the claims.
