Definitions

  • the present invention relates to a container for sterilization and preservation of preparations, in particular food, comprising several separate components, of the known type "tray" with low horizontal structure, made of plastic or plastic + metal composite, compatible for food use and operating temperatures; comprising several compartments for the separate packaging of components of a different nature from a complete cooked preparation, for sterilization and long-term preservation for deferred consumption.
  • sterilization and preservation containers are used, to subject foodstuffs sheltered from air, a heat treatment intended to destroy the microbial flora, thus making food sterile. and suitable for long-term storage in the container itself and at room temperature.
  • the cover which hermetically insulates the container from the outside environment, simultaneously insulates and hermetically the compartments from one another.
  • the components remain completely and hermetically isolated, both during the sterilization or pasteurization treatment and during storage until consumption. It is therefore there, in fact, juxtapositions of components more than real cooked preparations, due to the absence of aromatic exchange, which can, alone, create the unity that is expected from a composition fully cooked.
  • the present invention aims to remedy these drawbacks and, to this end, it provides a container for preparing complete cooked preparations (meats, garnishes, sauces or spices), using the specificity of each of the elements, all by adding, through an aromatic migration from one compartment to another, the character of a quality cooked dish.
  • the container according to the invention comprises several compartments covered over their entire open surface by independent and superimposed means, .
  • the other insulates the container in a completely sealed manner vis-à-vis the external environment.
  • Said means making it possible, by the combination of their heat-sealing, in a confined environment, sheltered from external pollution: .
  • the migration between the gas and vapor compartments developed by the rise in temperature during the sterilization treatment, .
  • the stabilization of the aromatic atmospheres thus created, by sealed isolation of the compartments after the thermal sterilization treatment.
  • the compartments are adapted to contain each, a component of a complete cooked preparation capable of emitting or receiving aromas and smells, during a treatment by thermal action, thanks to which, during sterilization, the container allows: .
  • the sterilization treatment with gases loaded with aromas and aromas coming from the emitting component (s) enclosed in one of the compartments, perfume the receiving component (s), enclosed in another compartment. .
  • the sterilization treatment stabilize the aromatic atmospheres thus created for conservation of the separate components until consumption.
  • the advantages obtained thanks to this invention essentially consist in that: .
  • the components of a different nature, enclosed in separate compartments, are sterilized in their own environment, which allows them to retain their specific texture and taste. .
  • the aromatic migration which takes place during sterilization provides the "extra" necessary for any quality cooked preparation. .
  • After sterilization and aromatic osmosis, the components of a different nature are kept until consumption in separate atmospheres, which avoids the degradation and standardization of the flavors observed in the unique capacities. .
  • the means ensuring the aromatic exchange during the sterilization treatment, then the isolation of the compartments after this treatment which are the basis of the invention make it possible to solve one of the major problems of sterilization.
  • the means which allow the passage of gases carrying aromas and aromas, while opposing the passage of liquid or solid materials are constituted by a plastic membrane for example : coextruded polypropylene bioriented sealable on both sides, covering all of the open surface of the compartments, above the filling limit of the products, and comprising, opposite each of the compartments, over the entire surface, or concentrated, of micro-pores; said membrane cooperates with the free edge of each of the compartments by heat sealing thus opposing any exchanges, other than those, gaseous concentrated in the porous zones provided for this purpose.
  • a plastic membrane for example : coextruded polypropylene bioriented sealable on both sides, covering all of the open surface of the compartments, above the filling limit of the products, and comprising, opposite each of the compartments, over the entire surface, or concentrated, of micro-pores; said membrane cooperates with the free edge of each of the compartments by heat sealing thus opposing any exchanges, other than those, gaseous concentrated in the porous zones provided for this purpose
  • the container provided with the gas permeable membrane is hermetically isolated from the external environment by a sealing film made of plastic or plastic metal composite which cooperates indirectly with the edges of the compartments by trapping the membrane in two stages. . One before sterilization, isolation of the container on peripheral edges. . The other after sterilization, isolation of the compartments on dividing edges.
  • the containers and the lid may be produced: .
  • thermo-formed plastic compatible with food use and processing temperatures, for example: coextruded multi-layer polypropylene with high barrier reinforcing the resistance to permeability of gases, water vapor and light.
  • the container according to the addition allows the implementation of a process for the preparation of medium and long cooked preparations. conservation by: . Separate packaging of specialties, meat or fish, side dishes, sauces or spices, garnishes, . A heat preservation, pasteurization or sterilization treatment carried out separately for each of the components, . A mixture of the aromas and flavors between the components during the heat treatment, . Storage in specific environments separate from each of the components until the time of use.
  • the container is horizontal and has at least two compartments 1 and 2 located side by side.
  • Each of the compartments 1 and 2 has on three of its sides a surface 13 bordering the container peripherally and reserved for the heat-sealing of the membrane 4 and of the cover 5 which we will describe below.
  • the compartments 1 and 2 are separated by a common surface 14, connecting the peripheral surface 13 and reserved for the heat-sealing of the membrane 4, before the sterilization treatment.
  • the common surface 14 to the two compartments 1 and 2 can be produced in a curve, for example: arc of a circle, the ends of this arc is located at the peripheral surface 13 and the maximum deflection in the common axis of the compartments is a few millimeters.
  • the membrane 4 which will cover the free orifice of the compartments 1 and 2 comprises: .
  • a peripheral surface 43 and an intermediate surface 44 able to cooperate by heat-sealing with the surfaces 13 and 14 of the compartments 1 and 2.
  • micro-pore zones 41 and 42 located on either side of the separating limit 44 and at the right of each of the compartments 1 and 2.
  • the cover 5 which will isolate the compartments 1 and 2 from the external environment comprises: .
  • a surface 53 capable of cooperating by heat-sealing with the peripheral surface 13 of the compartments 1 and 2, thus making the membrane 4 captive.
  • an intermediate surface 54 capable of cooperating by heat-sealing with the surface 14, this operation definitively stops the aromatic exchange between the compartments 1 and 2 for separate storage of the different components.
  • the container has 3 compartments 10-20-30 for the treatment of preparations with 3 components for example: meat, garnish, sauce or spices.
  • the means 50 ensuring the tightness with respect to the external environment, and 40 ensuring the aromatic exchange between the compartments are of the same nature and have the same function as the means 5 and 4 described for the container with two compartments of FIG. 1 .
  • the container is closed by placing the membrane 4 only after the heat-sealing of the corresponding surfaces 13 and 43 - 14 and 44, cleaning for each of the compartments a zone 41 or 42 permeable to gas.
  • the assembly is then isolated from the outside environment by heat-sealing the cover 5 between the peripheral surfaces 53 and 13. This operation is carried out with the means allowing the evacuation of the air and its replacement by a neutral gas. .
  • the container is then subjected to heat treatment in a pressure autoclave or any other suitable equipment.
  • the temperatures and durations of this treatment will depend on the nature of the components and the objectives of short, medium or long storage.
  • the aromas or flavors released by the temperature rise of the components will escape through the zones 41-42 provided for this purpose at the level of each of the compartments 1 and 2 and mix together, creating thus the unity and harmony that make the character of a quality cooked dish.
  • compartments 1 and 2 After the heat treatment and in order to avoid the conservation of the components in a uniform aromatic atmosphere, which, in the long term, would cause an alteration in the taste and a change in consistency of the components, in particular of the meats, compartments 1 and 2 will be definitively isolated from each other by heat-sealing the bearing surface 54 of the cover on the separating bearing surface 14 of said compartments.
