Description

Packaging in flexible material for the transport of perishable products.

  The invention relates to a packaging made of flexible material intended to allow the transport of perishable products. The packaging according to the invention is

  thus particularly suitable for the transport of seafood and freshwater products.

  The transport of perishable foodstuffs is subordinate in its efficiency to the maintenance over time of the bacteriological, chemical and physical qualities of the transported product. By maintenance over time of these qualities, the conservation in the strict sense of the product as well as any minimal non perceptible modification by even the most demanding consumer who is not likely to

  present any danger to his health.

  The maintenance of the different qualities of the products transported is obviously

  ment necessary to allow the sale of the products in question since a lack of this maintenance inevitably leads to a degradation of the organoleptic qualities, and in particular the taste, visual, olfactory and possibly tactile qualities of the product and consequently a disaffection on the part

of the consumer.

  Another problem posed by the transport of perishable foodstuffs appears according to the environmental nature of the transported product, this one being able to be accompanied in its transport by other elements whose nature can cause

  requirements as to the means used to carry out the transport.

  Thus, for example, crustaceans and molluscs are frequently accompanied, during transport, by seaweed and / or seawater which favor

  increasing their shelf life, on the one hand by decreasing the increase

  tion of the temperature during the operation and, on the other hand, by creating a pseudobiological environment favorable to the maintenance of the life of the transported organisms Transport can then be complicated by the leakage of water through the walls of the container used for transport, leak that causes various soiling, especially inside vehicles (cars, coaches,) in which the means used to transport these perishable goods are placed This problem is increased when these perishable goods consist of living organisms equipped with pungent, pinching or cutting defense systems such as many crustaceans (crabs, crayfish, lobsters, lobsters, langoustines, spider crabs) or sea urchins Indeed, the activation of these defense systems allows the animal to cut the containers that are conventionally used for its transport, such as plastic bags, and thus authorize its own leak or that of the water or the goémon which accompany it In addition, and within the framework of the use of many containers, the transport of crustaceans with pincers is made difficult by the presence, inside these containers, of '' roughness constituting as many catches allowing said crustaceans to leave the container or

section more easily.

  These various problems occur frequently during transport

  made by the consumer from the point of sale to the place of consumption.

  Thus, seafood and freshwater products are sold to consumers.

  teurs en poissonnerie To transport the products purchased, consumers empirically use all kinds of containers such as plastic bags, nets, baskets, etc. since there is currently no packaging dedicated to this kind of transport This results in various incidents due to the problems cited above and dissatisfaction, in particular of coach operators

  transporting tourists who buy this type of product.

  At the time of sale to the consumer, the sinful products are displayed for sale without packaging. There is therefore a break in the cold chain, a break likely to promote the rapid development of microorganisms and causing an acceleration of cellular degradation processes and inducing

  therefore a possible risk for the consumer.

  The object of the present invention is to provide a packaging made of flexible material for the transport of perishable foodstuffs, having qualities enabling it to respond to the various problems developed above and showing

other advantages.

  The packaging according to the invention also makes it possible to transport perishable goods, such as seafood and freshwater products, without any leakage.

  water or any other material It also allows, in a preferred variant

  tial of realization, to ensure a better conservation of the transported product by delimiting an interior volume globally impervious to radiations and, in

  particular, in daylight and heat.

  The packaging according to the invention, of minimal production cost, is an optimal packaging usable by the consumer for transport from the place of sale to the place of consumption. In addition, as regards the transport of crustaceans, the volume delimited by the packaging meets darkness criteria and

  maintaining temperature and humidity creating a pseudobio-

  logic to keep crustaceans alive and instinctively calm,

  which facilitates the transport operation.

  The packaging according to the invention also has, in an interesting embodiment, an internal volume delimited by smooth walls making it impossible to cut or cut these walls by the clamps or the

shell of crustaceans.

  Another particularly advantageous advantage of the packaging according to the present invention is that it is produced by the volume of a single blank.

  flat according to simple handling accessible to any user.

  According to the invention, the packaging made of flexible material for the transport of perishable products, such as seafood and freshwater products, consists of

  in one piece with a container part surmounted by a shutter part

  lation forming cover It is characterized in that it has intrinsic means making it possible to ensure total tightness with liquids of the container forming part and in that it is produced by the setting in volume of a cutout

single plane.

  According to a preferred variant of implementation of the invention, the part forming the cover of the packaging is able to cooperate with the part forming

  container so as to ensure the overall tightness of the packaging to radiation.

  Preferably, the interior volume formed by the forming part

  lid closed on the container part does not have any roughness.

  Also preferably, the flexible material constituting the packaging is chosen from among the materials making it possible to maintain the humidity.

in the interior volume.

  According to a particularly advantageous embodiment, the packaging according to the present invention is produced by setting up a flat cutout comprising a bottom and four lateral faces, these lateral faces being interconnected two by two by bellows Each of these bellows is formed by two

  angular sectors separated by a central fold line.

  The central fold lines allow the sectors to be brought together

  angular during volume setting.

  Advantageously, two of the opposite lateral faces are extended by flaps which can be brought back onto the bellows when these are folded during

  the operation of the volume setting of the cut.

  According to an advantageous arrangement, the flaps can be provided with lateral lugs capable of cooperating with notches located at the level of the closing flaps. Preferably, two of the opposite lateral faces are each extended by a closing flap, these two closing flaps being able to be

  joined in a single plane when the cut is created.

  Additionally, these closing flaps can each be extended by a tab, these two tabs being pierced with an opening, the two openings

  that can be compared when setting in volume to form a handle.

  Advantageously, a locking tongue is cut out in each of the flaps and each of these locking tongues is pierced with a slot capable of cooperating, during the setting in volume, with notches cut out on the legs. In order to be able to observe the product contained inside the packaging, at least one of the closing flaps is preferably provided with a

closable window.

  Interestingly, the material constituting the packaging is a cardboard coated on its inner face, that is to say the face intended to delimit the volume.

  inside once the cut is set in volume, a thermofusible food resin

  ble Advantageously, this hot-melt food resin can be made

polyurethane foam.

  The invention and the multiple advantages it presents will be more

  easily understood thanks to the description which follows of a nonlimiting example

  of the invention, with reference to the drawings in which: FIG. 1 represents a front view of a blank whose volume setting makes it possible to obtain a packaging according to the invention; Figure 2 shows the packaging obtained by the volume of the
