Definitions
- the present invention relates to a packaging for long-term storage and preservation intended for fresh products tending to exude a liquid capable of significantly reducing their period of consumption.
- This type of packaging is intended to preserve products, in particular seafood or meat, for a period of up to twenty days, and is used in an industrial type distribution process for products considered fresh. In other words, it is a packaging used by manufacturers, upstream of the consumer sales circuit, to ensure the conservation during the succession of the various links in the distribution chain.
- the first is resolved by introducing a gas into the sealed volume after having evacuated therein, said gas mainly having the function of ensuring preservation.
- a good solution consists in using a buffer located between the bottom and a false bottom on which the said product rests, the assembly constituting a packaging tray known per se.
- This buffer also contains a water-reactive agent capable of modifying the atmosphere according to the fumes of the products, by ventilation effect.
- the original structure of the packaging of the invention aims to respond to the problems posed above, by proposing a container type of external container, intermediate buffer and false bottom fitted into the container, with a gas circulation device. internal or, according to another terminology, a ventilation device.
- the invention is characterized in that the false bottom comprises a first group of orifices allowing the exuded liquid to be brought into contact with the tampon, and a second group of orifices situated between the useful volume of capacity of the packaging and a volume defined between the external container and the false bottom and / or the parts of the buffer not in contact with the exudate, so as to establish gas exchanges between the two volumes mentioned.
- the respective shapes of the false bottom and the buffer are provided so as to prevent any contact between the product to be preserved and said hydrosensor buffer.
- the outer container has reliefs intended to establish a gas circulation between the tampon and its bottom. These reliefs in fact provide passage zones towards the orifices of the second group. They are in fact canal conduits arranged between flat raised zones supporting the tampon, said conduits intersecting and opening into a peripheral zone of the bottom which communicates with said orifices of the second group.
- one of the faces of the tampon receives the exudates which pass through the orifices of the first group, that is to say those which are formed in the flat part of the false bottom.
- the other side is indirectly oriented towards the orifices of the second group, as well as the lateral sides. This second face rests on the raised areas and gives on the channels of the bottom which intersect, allowing the circulation of the gaseous fluid.
- the channels open into a peripheral zone at the bottom of the container, of the same level and located near the orifices of the second group, which are generally located on the part of the false bottom opposite this peripheral zone.
- the exudates when they cross the false bottom, are absorbed by the buffer which performs its chemical function of neutralization and regeneration.
- the fumes from the product are therefore inhibited by the buffer which also regenerates the atmosphere, with the help of a gas circulation allowed by the two groups of orifices which in fact create a closed ventilation circuit inside packaging.
- the only obstacle to the gaseous fluid is constituted by the buffer, one of the faces of which is directed towards one of the groups of orifices, while the other face is rather oriented towards the other group of orifices.
- the nature of the material used to produce said buffer causes the liquid to stop, which cannot cross the obstacle, and simple resistance in the gaseous fluid ventilation loop.
- the air or more generally the regenerated gas can be "reinjected” into the useful volume containing the product, by through the orifices of the second group. Further on, in the gas circulation circuit, at the level of the absorption zones of the exudates by the buffer, the gas is in contact with the said exudates, after having been the product to be preserved proper. It is therefore “vitiated” and requires the regenerative treatment carried out by the tampon.
- the outer container also has reliefs on the bottom intended to support the false bottom, or even to fix it. These reliefs, even if they are arranged over a large part of the length or width of the container, should not prevent the circulation of the gaseous fluid. In particular, they give access to the peripheral zone on which the orifices of the second group give.
- the tampon may also include orifices, preferably located opposite the orifices of the first group, and forming small exudate reservoirs while the liquid is being absorbed by the tampon. Since the channels at the bottom of the container have the essential function of circulating a gaseous fluid, it is clear that they cannot be opposite the holes in the tampon, so as not to be filled with exudate. The very function of the buffer would no longer be ensured, since we would then be left with gaseous fluid in contact with the exudate on either side of the regenerating buffer.
- the shape of the orifices in the first group of the false bottom is chosen so that the liquid is trapped when it falls into the holes in the tampon.
- the walls of these orifices are funnel-shaped protruding from the false bottom so that the narrow necks of said funnels are introduced into the holes in the tampon.
- the ends of said funnels are moreover preferably conical, in order to further reinforce the trapping effect of the exudates.
- the orifices of the second group are preferably located in the part of the false bottom having an appearance substantially parallel to the peripheral walls of the external container, and near the zone for fixing said false bottom to the container.
- orifices may not be perforated in the false bottom, but result from residual spaces remaining between the external container and said false bottom, when the latter is fitted therein and welded.
- the packaging of the invention must be provided with a tamper-proof water-absorbing pad. This is why the false bottom is generally welded to the container.
- the outer container and the false bottom are preferably made of polypropylene.
- Said outer container (1) comprises two types of reliefs to be distinguished, because they fulfill two different functions.
- the reliefs (4) intended to allow the circulation of the gaseous fluid.
- these are flat prismatic mounds (4) separated by channels (5) which intersect and open out in a peripheral zone (6) partially blocked by a second type of relief (7).
- the latter (7) are intended to support, or even fix (for example by welding, thermal or ultrasonic ...) the false bottom (3).
- the peripheral shape of these mounds (4) does not matter, provided that the channels which separate them intersect to allow free passage of the gaseous fluid and they open into the peripheral zone (6).
- the rim (17) of the false bottom is welded at this shoulder (9), as well as at the reliefs (7).
- the container (1) and the false bottom (3) are welded in order to make the space between them inviolable.
- This shoulder (9) is extended by a terminal edge (10) on which the film is heat sealed (not shown).
- the buffer (2) is applied between the reliefs (7) which help in its installation by delimiting its positioning area. It is provided with cylindrical holes (11) which pass right through it, and are arranged so as to be approximately centered on the flat mounds (4) for the reasons explained above, aiming in particular to prevent exudates from arrive in the channels (5).
- holes (11) correspond to the orifices (12) of the false bottom (3) with which they are substantially coaxial in the assembled position.
- the liquid penetrates there and is gradually absorbed by the tampon (2) at the walls of said holes (11).
- These vertical walls are therefore of great functional importance, as will also be seen hereinafter, in combination with the orifices (12) known as of the first group, those of the planar part (13) of the false bottom (3).
- These (12) have in fact a funnel shape making it possible to guide the liquids which flow from the main volume of the container (V) into the cavities which form the holes (11) of the pad resting on the flat mounds (4 ) from the bottom of the container (1).
- the ends (16) of said funnels are preferably conical, and serve to trap the liquid in the volumes formed by the holes (11).
- the false bottom (3) comprises two distinct parts: a flat bottom (13) bearing on said mounds (4), and flanges (14) which rise up towards the upper peripheral edge (10) of the container (1), substantially parallel to the edges of said container (1).
- Figure 2 shows particularly clearly the end portions (16) funneling the orifices (12) of the first group, protruding from the surface (13) of the false bottom (3) to be inserted in the corresponding holes (11) of the buffer (2).
- Figure 3 is a cross section, but a longitudinal section would have been strictly equivalent, due to the existence of symmetry with respect to a central axis perpendicular to the bottom of the tray. It shows the systematic offset that exists between the channels (5) of the bottom of the container and the funnels (12) of the false bottom (and therefore the holes (11) of the buffer).
- the circulation of gas in the peripheral zones (6) towards the orifices of the second group (15) is also clearly demonstrated.
- the orifices (15) can also be residual spaces formed between the container (1) and the false bottom (3), at the level of the rim (17) for fixing the false bottom to the shoulder (9), and making office of ventilation points.
- the hermetically sealed container generally contains a gas injected at the time of sealing, the preservation properties of which are adequate.
- the object of the invention is mainly oriented towards the structure of the tray and its three elements, with variants which remain in the spirit of what is claimed.
- the chemical compositions of the inhibitor intended to neutralize the fumes of the products and of the regeneration reagent can be of all types without changing the nature of the invention.
- the synthetic materials used for the manufacture of the container (1) and of the heat-sealed film can be complex, having characteristics preventing the crossing of gases, aromas and water vapor.
