Definitions

  • the present invention relates to an improved packaging intended more particularly for foodstuffs, this packaging being composed of a tray sealed hermetically by a removable cover.
  • the type of tray in question intended to significantly extend the period for storing foodstuffs, that is to say to extend the expiry date for sale, has within it an openwork dividing wall forming a "grid arranged substantially parallel to the bottom of the tray, thus ensuring a bipartite separation of the latter, so that the upper compartment is reserved for housing the foodstuff to be preserved, the lower compartment possibly divided into several volumes being intended for the reception of a material, preferably in sheet form, intended to absorb the exudate of said foodstuff.
  • This type of trays is well known and their design or production is mainly due to the fact that food of animal origin such as fish, meat, shellfish and crustaceans, let escape an exudate which can, on the occasion of contacts untimely or when storing its food, become a carrier of germs or other products and organisms harmful to humans.
  • botulism is a serious poisoning produced by the toxin of an anaerobic bacillus, that is to say drawing the elements necessary for its life from the organic substances which it breaks down.
  • the object of the present invention is therefore, on the one hand, to prevent the formation of the harmful by-products mentioned above and, on the other hand, to maintain, over time, the relatively constant pressure of the gases at inside the hermetically sealed package, and to create an atmosphere capable of compensating for the loss by entrainment by the exudate of some of said constituent components of said foodstuffs.
  • the invention provides an improved packaging intended more particularly for foodstuffs of the type composed of a tray sealed hermetically by a removable cover and comprising within it an openwork partition wall forming a grid disposed substantially parallel to the bottom of said tray. thus ensuring a bipartite separation of the latter, so that the upper compartment is reserved for housing the foodstuff to be preserved, the lower compartment being intended for the reception of an absorbent material having the purpose of absorbing the exudate of said foodstuff (known from GB-A-863 095), packaging characterized in that there is provided on or in said absorbent material, a material capable, under the effect of the water of the exudate, of releasing a inert gas in an amount capable of compensating for the pressure loss inside the tray on the one hand and, on the other hand, a particulate compound containing one of the comp daring of the foodstuff of the sodium chloride and / or trace element type and capable of being entrained by the flow of said gas thus released and capable of creating an atmosphere such as to prevent
  • the material in question is based on a substance releasing C0 2 and / or oxygen, the role of which is to maintain the desired pressure inside the tray.
  • the material in question contains a carbonate and / or a persalt in combination with a non-toxic organic acid.
  • carbonate of sodium carbonate or sodium bicarbonate of food grade, as parsley, percarbonate or sodium perborate and, as organic acid, citric acid.
  • said material contains as a substance capable of creating the desired atmosphere and of being entrained by the gas given off by said material, one of the components of the foodstuff entrained by the exudate.
  • a substance capable of creating the desired atmosphere and of being entrained by the gas given off by said material one of the components of the foodstuff entrained by the exudate.
  • said material will be in the form of plates, pellets, fragments, shavings, teabags or in powder form.
  • said material will be associated with said particulate compound and will advantageously correspond to the formula 50% sodium chloride, 25% citric acid and 25% sodium carbonate.
  • this formula will comprise 33.5% of sodium chloride, 33.5% of citric acid, 16.5% of a percarbonate and 16.5% of a perborate.
  • Figure 1 shows an example of packaging in perspective with partial cutaway.
  • FIG. 2 is a cross-sectional view to the right of the lugs of the container of the packaging presented in FIG. 1.
  • Figure 3 is a sectional view of another possible embodiment of the package.
  • Figure 4 is a top view of a separation grid present in the package.
  • FIG 1 we can see a package consisting of a tray 1, a separation grid 2, a sheet of material 3 absorbing the exudate of the foodstuff placed on the separation grid (not shown) , hermetically closed by a cover 4.
  • the separation grid 2 is a plate comprising ribs 5 and holes 6. It is embedded in the tray 1 by means of four lugs 7 projecting towards the inside of the tray and arranged in pairs on its side walls facing each other. Therefore, the separation grid 2 which has four protruding reliefs 8 in the form of studs, can not escape from the bottom of the tray 1 even in the event of a reversal thereof.
  • the studs 8 hold the sheet of material 3 absorbing the exudate of the foodstuff, pressed against the bottom of the tray 2.
  • This sheet of absorbent material 3 enters a peripheral channel 9 for draining the exudate, provided around a tier at the bottom of the tray. It has a substantially rectangular shape with cropped angles to adapt with minimum play in the lower compartment of the tray.
  • FIG 2 which shows a section of a tray 1 shows the stiffeners 10 and the pins 7.
  • the vertical stiffeners 10 are obtained by a suitable forming of the side walls of the tray.
  • the bottom of the tray 1 has a step 11 which is. connects to the side walls 12 of the tray 1 by a peripheral channel 9.
  • a cover 4 On the upper edges 13 parallel to the bottom of the tray 1 can be welded a cover 4.
  • FIG 4 In Figure 4 is shown, seen from above, a separation grid 2 with its ribs 5 and four studs 8 projecting from the other side of the separation grid 2.
  • the ribs 5 have a central flat surface 15 substantially parallel to the plane defined by the body 16 of the separation grid 2 pierced with holes 6 to ensure the flow of the exudate towards the sheet of material before absorbing it.
  • central flat surfaces 15 can be bonded to the sheet of absorbent material 3 which is itself partially bonded to the bottom of the tray 1.
  • the studs 8 can have any suitable conical or hemispherical shape for example.
  • the sheet of absorbent material 3 comprises within it or on its surface plates, pellets, fragments, chips, teabags or a powder essentially consisting of a compound capable of giving off an inert gas such as C0 2 and / or oxygen under the action of the water from the exudate in the presence, advantageously, of a non-toxic organic acid and a substance capable of being entrained by said gas to create an atmosphere or a mist at within the tray of the type described above.
  • said mist or said atmosphere will preferably be constituted by sodium chloride to compensate for the loss of the latter during the exudation of said fish.
  • the absorbent material will contain sodium chloride which will be entrained, for example, by the carbon dioxide formed by virtue of the presence on or in the absorbent sheet of food grade sodium carbonate or bicarbonate and citric acid.
  • oxygen can also be provided by the presence, for example, of a percarbonate and / or a perborate.
  • composition containing (by weight) 50% sodium chloride, 25% citric acid, 25% sodium carbonate or 33.5% sodium chloride. sodium, 33.5% citric acid, 16.5% percarbonate and 16.5% perborate.
  • the gas evolution which is obtained compensates for the pressure loss which may occur inside the tray, thus preventing its deformation and the salt or trace element entrained by said gaseous release on the one hand, compensates for the loss of mineral salts or of the trace element entrained in the exudate and on the other hand, prevents the harmful production of harmful secondary products.
