Definitions

  • the present invention relates to a new device for packaging and preserving fresh food products, intended in particular for meat, seafood products and the like which tend to exude liquids which promote the proliferation of bacterial flora inside a transparent film. which envelops and isolates the product / packaging unit from the outside.
  • Such packaging devices have been known for a long time, consisting of a tray of synthetic material such as polystyrene, on which the product to be presented is placed, the assembly being wrapped in a transparent impermeable film such as polyethylene.
  • This reputation is linked at least in part to the appearance of these products through the transparent film which constitutes the only means of protection of the product presented on the tray, and it is true for example that the sight of a meat placed on a tray stained with blood, or the bottom of which is soiled with exudate, makes the appearance of the product unattractive to the consumer.
  • the patent application PCT-WO-86 07036 describes a container of this kind in which the exuding product, for example a meat, is placed on a first element or false bottom comprising openings and welded directly on parallel rectilinear ribs of '' a second element or background, so as to allow the exuded product, for example the blood, passing through these openings to be collected in a space between the two elements, in order to remove the blood from the view of the buyer , to overcome the aforementioned drawback.
  • the exuding product for example a meat
  • These parallel rectilinear ribs define compartments which are parallel to each other between the two elements, that is to say in which said exuded product, although forced to remain in said compartments when the container is tilted by tilting about an axis parallel to said ribs, on the other hand, can freely accumulate on one or the other of the two other perpendicular sides of the container when the latter is inclined around an axis perpendicular to said ribs.
  • Another solution consists in placing the product under consideration in contact with a material having absorbent properties. It would not be advisable to use for this purpose a tray whose bottom would be absorbent, because it would preserve on the one hand an appearance as evoked above, and because the humidity of the material, which would be constantly in contact with the product, would aggravate the problem of preservation and risk degrading said support material due to the pressure of the product filmed on the tray.
  • the absorbent layer inherently extends the wet area over the entire possible surface, depending on the volume of liquid passing through the orifices and the absorbency of the pad / blotter. The latter therefore tends to propagate the very cause of the preservation problem encountered in such packaging.
  • the second problem related to the packaging technique considered is mechanical in nature.
  • the transparent film is of the heat-shrinkable film type, that is to say having the property, on heating, of reducing dimensions by pressing against the periphery of the volume that it surrounds.
  • This technique is widely used for the packaging of many products, and it has the advantage of immobilizing a product on its support, and above all eliminating a large part of the air enveloped in the film before heating, thus subtracting a food product to the action of oxygen.
  • the weight of the product contained in the tray tends to cause its deformation, especially in the case where this product is relatively large, for example if it s is a flat fish.
  • Australian Patent No. 631,520 describes a packaging for meat, the elements of which, namely a bottom and a false bottom, each include reinforcing ribs. These ribs serve, in the event of impact, to prevent absorbent material, contained in sachets housed in a space situated between said two elements, from being released by the rupture of these sachets.
  • the present invention relates to a new device in which means are provided for jointly and simultaneously solving the two aforementioned problems, namely eliminating the effects of any exudate released by a product packaged in a container of the aforementioned type, and making said container non-deformable notwithstanding the stresses created in particular by the film enclosing said product in said tray.
  • said ribs are therefore advantageously distributed in such a way that the orientation of each rib at each of its ends is substantially perpendicular to two adjacent sides of the bottom.
  • the ribs can take any geometric shape.
  • they can have a polygonal appearance, in which case, according to the simplest embodiment, they can be formed of two branches joined together at an obtuse angle.
  • only a portion of the bottom comprises ribs, and another constitutes a continuous raised zone of the same height as the ribs, this zone possibly representing any fraction of the surface of the bottom.
  • these ribs have a rounded shape, and more especially they have a general shape of arcs of ellipses distributed according to four groups corresponding to the four zones rectangular of the bottom defined by its two axes of symmetry, each of these elliptical arcs having an elongated shape, one of its ends being located along one side of the bottom or in the vicinity and being substantially perpendicular to this side, and the other end being located along an adjacent side and being substantially perpendicular to that side, said compartments having a corresponding rounded elongated shape.
  • the bottom is made practically non-deformable even under the action of the peripheral stresses created by the heat shrinkage of said film
  • all of said compartments constitutes a network in each of the meshes from which opens at least one of said orifices, in order to channel, isolate and immobilize therein as many individual fractions the portion of said liquids having passed through the false bottom by said orifices by preventing said fractions from moving throughout volume by being likely to accumulate in one area or another, where they could contaminate the said product.
  • said reliefs, or ribs can take various aspects, since, at each point, from one of its ends to the other, thanks to its curvature, each rib will contribute to buckling resistance from the bottom in the direction corresponding to the location of this point.
  • said ribs may be concave or convex towards the outside of the bottom surface. They can remain each individual or join in pairs or four.
  • the compartment created between two consecutive ribs will simply be elongated in general elliptical shape from one edge of the bottom to the adjacent edge, or in the shape of a curvilinear V or in the shape of a curvilinear rectangle or square, it being understood that, preferably according to the invention, each compartment must correspond to at least one orifice of the false bottom.
  • each orifice extending downwards by a frustoconical flow chute, it is provided, according to the invention, to initiate by capillarity said flow, to practice in the upper surface of the false bottom, an inclined channel opening into the '' upper mouth of each orifice, the depth of this channel increasing in order to reach, at the location of said orifice, the height of said chute.
  • the invention therefore ensures the evacuation of the exudate from the conditioned product and its fractionation into small volumes immobilized between the bottom and the false bottom out of any contact with said product.
  • some of these small compartments due to geometric considerations, can keep a certain length, over which a small fraction of exudate could still travel, it follows from the rounded shape on which this path would be made, that this fraction would spread and adhere along the rounded wall of this compartment without the risk of accumulating at any point in the volume between the bottom and the false bottom.
  • Such a buffer can contain, in addition to hydrocaptrating substances, other antibacterial and / or hydroreactive substances regenerating the atmosphere and contributing to the conservation of said products after packaging.
  • the device according to the invention is made up in a known manner of a rigid waterproof bottom 1 and a false bottom 2 comprising perforations 3, the bottom 1 and the false bottom 2 being joined together along their periphery 6, by welding or fitting, so as to provide between them a hermetic space 7 appearing in FIGS. 4 and 5.
  • the bottom 1 comprises, from the molding, ribs which are referenced, on one of the quadrants of the bottom, from 8 a to 8 h , from the outside (corner C 1 ) towards the center. On the other three quadrants, symmetrically, the same ribs are provided.
  • the false bottom can be welded both on its periphery and on top of each rib.
  • the ribs 8 a -8 h define, between them and between the bottom 1 and the false bottom 2, compartments isolated from each other, and having either an elongated shape from edge 10 to edge 12, such as compartment 23 located between the ribs 8 d and 8 e , and compartment 24 located between the ribs 8 b and 8 c , or a shape open only on the side 12, such as compartment 25, opening between 8 c and 8 d , or a V shape such as 26 between the sides 12 and 27, and closing at 28 between 8 th , 8 f , 8 th ' and 8 f' , or a closed curvilinear square compartment 29 defined between the four ribs 8 g , 8 g ' , 8 g'' , 8 g''' .
  • the small amount of exudate that can be collected in each compartment from the orifices 3 of the false bottom 2 is itself very small, completely isolated and immobilized from one compartment to the other, and that, by manipulation of the tray, can only travel along elongated and rounded paths along which it cannot accumulate but on the contrary be divided into even more tiny fractions. It is therefore completely impossible for the exudate to accumulate in any zone of the bottom 1, even by tilting the latter at a strong inclination, and all the more reason, to return to contact with the product placed on the false bottom.
  • FIGS. 4, 4a and 5 have shown an additional absorbent pad 30 placed under the false bottom 2, and which further reduces the amount of exudate reaching the preceding compartments through the orifices 3.
  • said absorbent pad 30 is perforated to let through the orifices 3 which sink therein due to their frustoconical shape.
  • At least one channel or flow initiator 31 which are shown in FIGS. 3, 3 a and 6.
  • These channels are triangular and of increasing depth so as to open out at level 31 'from the bottom of the orifice 3.
  • These inclined channels are in number and arrangement such that they collect all the exudate and bring it to the orifices 3, which , as shown in Figure 6, are distributed above all the compartments 23, 24, 25, 26, 29 and the like defined by the ribs at the bottom.
  • the channels 31 are, for each orifice 3, oriented parallel to the direction of the corresponding compartment in order to initiate by capillarity the flow of the exudate in this compartment.
  • this configuration of the orifices and channels has the effect that the exudates evacuate towards the hermetic space 7 even in the very inclined position of the tray presented to the customers, while each chute of an orifice 3 having a frustoconical shape, as best seen in Figure 3a, the exudate thus collected in space 7 can no longer return to the product resting on the false bottom 2, even if the tray is completely inverted.
  • the buffer can then also contain hydroreagents regenerating the atmosphere initially injected. It is then necessary to treat the atmosphere both around the product and in the hollow areas of the bottom.
  • ribs mechanically in the case of the use of a heat-shrinkable film, but it is understood that they fulfill the same role if the tray is closed by welding on the periphery of its upper edge with a non-shrinkable but stretched film, for example made of polyethylene, PVC, polyethylene terephthalate (PET) or the like, having barrier properties (liquid and gas tight) or not.
  • a non-shrinkable but stretched film for example made of polyethylene, PVC, polyethylene terephthalate (PET) or the like, having barrier properties (liquid and gas tight) or not.
  • the polyethylene film by which the packaged product is enclosed under vacuum on the false bottom of the package is generally of the heat-shrinkable type, that is to say that, after having wrapped the assembly in this film, this the latter is sealed by passage through a heated zone, which causes the shrinkage of the film which is applied tightly over the entire outer surface of the tray and its contents, expelling practically all of the air.
  • the film is thus applied under tension, which has the effect, in addition to this vacuuming and this protection against the outside, of exerting at all points of said surface, a significant contraction stress.
  • the tray is made for example by thermoforming a relatively very thin polystyrene sheet, for obvious economic reasons, so that its bottom is relatively flexible.
  • Parallel rectilinear ribs, of the known type, can only stiffen this bottom in one direction, which means that said bottom can perfectly bend or twist in all other directions, under the peripheral action of the tension exerted by the shrunk film.
  • the ribs according to the invention oppose to this action a resistance oriented at each point in the direction of the stresses exerted on this point.
  • the ribs are precisely oriented parallel to these axes, respectively in the longitudinal direction in the vicinity of the edge 10 and the opposite edge and in the transverse direction in the vicinity of the edge 12 and the opposite edge.
  • the shape of the ribs opposes the buckling of the tray 1, in a longitudinal direction under the effect of the stresses exerted on the two short sides and transverse under the effect of the stresses exerted on the two long sides.
  • each rib is opposed to the torsion of the bottom against the stress exerted at this point tangentially to said rib.
  • the pattern of ribs distributed in four elliptical quadrants on the bottom 1 therefore constitutes the ideal physical model for opposing any deformation of this bottom under the action of the peripheral stress exerted on this bottom.
  • Said ribs with their shape and their distribution, therefore fulfill a double function, providing the solution to the double problem set out above.
  • the ribs formed in the bottom 1 stop at a certain distance from the upper edge of this bottom. This allows convenient stacking and reduced size of the trays, each of which rests on the end of the ribs of the one below, thus preventing their blocking and facilitating their separation.
  • volume of exudate is variable depending on the product packaged.
  • it can represent 1% of the weight of a slice of red meat, 3% of a slice of a piece of tripe, for example liver, and up to 5% d fresh fish, each of these weights corresponding to a volume related to the density of the exudate considered, for example blood or salt water.
  • a larger fish (or fish fillets) (e.g. 300 or 400 g) will exude a proportionally larger amount of exudate, but this overall amount will be subdivided into a larger number of small individual volumes, since the tray will also be greater.
  • the principle of the device according to the invention is based on a subdivision of this overall volume into a large number of individual volumes, isolated from each other, and proportionally much smaller, in contrast to the large volumes of devices such as that of PCT N ° 86 07036 cited first.
  • the overall volume of this exudate is subdivided into individual individual volumes, each of which does not exceed, at most, about 1.5 cm 3 , and is preferably substantially less.
  • the false bottom can be adapted to the bottom by any process ensuring the tightness of the connection: welding, clipping and the like, preferably the assembly is such that the common flange 6 is oriented inwards at 32 for make handling of the trays more pleasant than if this rim is sharp and oriented towards the outside.
  • Another essential aspect of the invention residing in the creation, between the bottom and the false bottom, of closed volumes delimited by successive ribs, it is clear that, depending on the height of the ribs relative to the bottom, such volumes will be more or less important for the same gap between the same ribs.
  • This height being to be taken into account for the other effect of the same ribs, namely their stiffening effect on the bottom, it will therefore be necessary, in each practical embodiment, to find a compromise between the linear dimensions of the bottom and of the ribs and the height of said ribs, as well as, where appropriate, their own width which contributes to the seat of the false bottom, given the volume of liquid that is expected to exude from each packaged product.
  • such an exudate will represent a greater volume when it comes from a fish than when it comes from a slice of red meat, and the ribs will have to be higher to ensure the stiffening of a larger bottom, for example intended to receive a flat fish, such as a turbotin of 30 x 15 cm, instead of a tournamentdos of 20 x 10 cm.
  • any variant or dimensional modification made to said ribs will fall within the scope of the invention. It will be the same for the shape of the cross section of the ribs, which may also vary from one rib to another depending on the general configuration. It will also be the same for the effective number of ribs formed on a determined bottom, a portion of this bottom possibly comprising ribs according to the invention, and another constituting a continuous raised zone of the same height as the ribs, this zone being able to represent any fraction of the bottom surface, both in the central portion and on the periphery.
  • each of the "elliptical arcs" as mentioned is practically formed of two practically rectilinear sections, joining at an obtuse angle, as illustrated very schematically in FIG. 7, which differs from FIG. 6 only in the relatively rectilinear shape of the segments 40, 40 ', 41, 41', 42, 42 ', ...
  • each of the ribs the orientation and the configuration of these segments being equivalent to those of each elliptical arc according to claim 1, the connection angles 43, 44, 45 of said segments corresponding to an orientation of the segments 40, 41, 42 perpendicular to the sides 10 to that of the segments 40 ', 41', 42 ', perpendicular to the side 12, which from the point of view of stiffening of the bottom 1 is practically equivalent.
  • the remarks relating to the dimensional relationships of the arcs of ellipses 8 are of course valid with respect to the segments 40.
  • the bottom of the tray can be made by any technique and in all materials such as polystyrene, polyethylene, PVC, PET, forming a barrier or not.
