Definitions

  • the present invention relates to packaging for multi-component food product as well as a product multi-component food packaging.
  • a packaging of the type consisting of at least one main container relatively rigid, closable, inside which is arranged at least a first component of the product food, with a lid surmounting said container, this lid being equipped with at least one auxiliary container closable inside which is arranged at least one second component of the food product, this container being able to open under the action of the heat to allow a gravity emptying of its contained in the main container for obtaining of a hot multi-component product.
  • Packaging that meets the constraints set out above have already been described in the literature, in particular in patents US-A-4,596,713 and FR-A-2,536,251.
  • the packaging described in US-A-4,596,713 is more particularly intended for the packaging of pop corn.
  • Such packaging consists of two sachets arranged one inside the other, the outer bag containing the constituent elements of the popcorn, the inner bag containing additives such as butter or oil.
  • the bag containing the additive is made of a material such as plastic film which softens during the heating inside the microwave oven. The action combined material softening and increased pressure inside the bag causes stretching then finally a random tear in the film causing the gravity dispersion of the contents of the sachet on the food inside the main outer bag.
  • the walls of the bag are joined by an adhesive inactivated by heater.
  • the solution in which an adhesive is used inactivated by heat does not describe the fate of this adhesive.
  • the solution in which the sachet is broken by softening then rupture under the combined effect of temperature and pressure inside the bag is particularly random because it is dependent on several factors such as the nature and quantity of food inside the package, humidity, the volume of the package, the thickness and the resistance to material rupture. All these parameters do not allow to guarantee in a safe way the rupture of this sachet.
  • the presentation of the packaging in the form of two bags contained in one another obliges the user, once the product has warmed up, transfer this product to another packaging, in particular a piece of dishes because it is very unpleasant for the consumer to have to consume a dish mixed with a burst bag in parts.
  • FR-A-2,536,251 describes a multi-component food product packaging having a main receptacle at the bottom of which are arranged food, a second container being arranged at the top of the main receptacle. All constitutes an airtight packaging.
  • a closed shutter isolates the content of the second container from that of the container of the main container.
  • This shutter can be realized either by partial cutting of the partition separating the two compartments by filling in the cut-out paraffin or wax, either by reporting on said partition, in which an opening is provided, a room in the form of a washer fitted with a tab sealed on the partition, the hot-melt material then being placed in the overlap area of the washer on the partition.
  • An object of the present invention is therefore to propose a packaging for multi-component food product whose design allows to obtain a lifetime and a product storage compatible with constraints economical without harming taste qualities and organoleptics of the multi-component food product.
  • Another object of the present invention is to provide a packaging for multi-component food product whose design allows easy reheating, in particularly in the microwave, food product without tedious handling, without addition of ingredient and while offering a pleasant presentation of the product hot food ready to eat.
  • Another object of the invention is to propose a packaging for multi-component food product whose design allows the implementation of operations classics in manufacturing and closing processes food packaging.
  • the invention relates to packaging for multi-component food product of the constituted type at least one relatively rigid main container, closable, inside which is arranged at least one first component of the food product, a cover surmounting said container, this cover being equipped with minus one closable auxiliary container inside of which at least one second component of the food product, this auxiliary container being likely to open under the action of heat to allow a gravity emptying of its content in the main container for obtaining a product multi-component hot, characterized in that the container auxiliary is closed by means of a shutter, such that a sealing film, welded to said container, the welding and / or the shutter member locally comprising zones of predetermined weakness respectively for the weld by the weld profile and for the sealing member by laser treatment to allow, when heating the whole packaging, at least local rupture welding and / or the sealing member allowing a emptying the contents of the auxiliary container into the container main.
  • the closure member of the auxiliary container is a film lidding arranged to roll up on itself in at minus a predetermined direction when at least one part of internal or external mechanical stresses to which the said film is subjected disappear.
  • Packaging for multi-component food product object of the invention, consists at least a relatively rigid, closable main container 1, inside which is arranged at least a first component 2 of the food product.
  • this first component 2 of the food product is constituted with fresh pasta.
  • this container main 1 affects the shape of a piece of dishes, such as a plate or dish, to allow direct consumption of the hot food product, such as this will be described below.
  • This main container 1 is by example made of a thermoplastic material, such as a thermoformable material, to facilitate its manufacture and give it a certain rigidity.
  • the main container 1 is closed at means of a shutter member 8, such as a film lidding, to be removed manually before heater.
  • This sealing film is preferably heat sealed at the periphery of the main container so that the packaging of the first component of the food product poses no technical difficulty.
  • This main container 1 is surmounted by a cover 3.
  • This cover 3 is equipped with at least one auxiliary container 4 closable inside which is arranged at least one second component 5 of the food product.
  • second component 5 of the food product can by example be constituted by a sauce.
  • This container relatively rigid auxiliary 4 is susceptible, under the action of heat, produced for example during a heating in microwave oven, to open to allow gravity emptying of its contents into the container principal 1 with a view to obtaining a hot multi-component product.
  • the auxiliary container 4 can be made of separate from cover 3 as shown in Figure 1. In this case, this auxiliary container 4 can affect for example the shape of a bowl inside which is placed the second component 5 of the food product.
  • This auxiliary container is in this case shaped to be held by fitting in the bottom side of the cover 3.
  • the auxiliary container 4 and the cover 3 are formed in one piece, the container auxiliary 4 being constituted by a cavity formed in said cover.
  • This cavity preferably affects a frustoconical shape, the base of the truncated cone constituting the closable area of said auxiliary container.
  • cover 3 and auxiliary container can be made in a thermoplastic material, such as a material thermoformable, giving them a certain rigidity.
  • the auxiliary container 4 is closed by means of a member shutter 6, such as a sealing film, welded to said container 4, in particular on the periphery of the latter.
  • the weld 10 and / or the closure member 6 comprise locally predetermined areas of weakness.
  • the zones of weakness are predetermined by the weld profile.
  • this weld is preferably thermal welding carried out for example at by means of a heating cord whose diameter is not constant so as to produce a weld which comprises locally areas of weakness predetermined by the weld profile.
  • These areas of weakness correspond therefore to the weld zones in which the width of the solder 10 is reduced. So, for example, the area of welding can include a part welded in 5 mm of wide and the rest in 2 mm wide.
  • the areas of weakness allow, when heating the entire conditioning, at least local rupture of the weld and, as a result, at least partial detachment of the organ shutter 6 of the auxiliary container 4 thus authorizing emptying the latter.
  • the areas of weakness are predetermined by treatment with laser of the shutter member 6 generally consisting of a sealing film. These areas are represented in 11 to Figure 5 and assign the shape of two cross lines to the surface of the sealing film 6.
  • the sealing film 6 is for example a multi-layer film with one layer, resistant mechanically, is subjected locally to a treatment with laser which weakens said layer along the lines of embrittlement shown in dotted lines in FIG. 5 without however, perforate said film. After embrittlement and lidding, this film, when subjected to a temperature increase, breaks due to pressure increase along the lines of weakening so as to leave a sufficient opening for emptying the contents of the auxiliary container 4 into the main container 1.
  • the closure member 6 of the auxiliary container 4 is preferably a sealing film arranged to wrap on itself in a predetermined direction when at least some of the internal or external mechanical stresses to which the film is subjected disappear.
  • external constraints we mean in particular the stresses exerted by the welding on said film.
  • internal constraints in particular the constraints generated by the film itself.
  • this lidding film stores forces capable of being released upon rupture of the weld or film, these forces are released so that the lidding film wraps around itself in at least one predetermined direction. Thanks to this film making sealing, the opening thus provided is sufficient to allow rapid and efficient emptying of the contents of the auxiliary container 4.
  • auxiliary container is closed by means of traditional techniques by heat sealing, which does not presents no difficulty for the manufacturer before close this auxiliary container 4.
  • cover 3 and auxiliary container 4 allow interchangeability easy of the auxiliary container 4 thus allowing a large range of products.
  • the bottom of the main container 1 preferably has a bulge 7 towards the interior of the main container 1, as this is shown in Figures 1 to 3.
  • the main container 1 comprises gripping, such as handles.
  • the lid 3 and the main container 1 are shaped to be stackable.
  • the whole packaging is, due to its design, storable at a temperature of the order of 4 ° C.
  • the length of the conversation of such conditioning can be at least equal to 21 days, duration common to most food products of this type.
  • Heating the contents of the container auxiliary 4 causes, due to the increase in temperature, an increase in pressure inside the auxiliary container, this increase in pressure generating either the rupture of the weld binding the element closure 6 of this auxiliary container 4 audit container, or the rupture of the closure member 6 along the lines of weakness 11.
  • the rupture of the welding causes detachment of the sealing member 6 of the auxiliary container and possibly the winding of this shutter member 6 on itself when it comes a sealing film.
  • the passage thus provided allows the the contents of the auxiliary container 4 are poured into the main container 1.
  • the rupture of the organ shutter 6 causes the spacing, possibly by winding, of the different parts constitutive of the film under the effect of gravity and by following the passage of the contents of the auxiliary container 4 in the main container 1.
  • the main container, the cover and possibly the auxiliary container are thermoformed products the manufacture of which is reach of any person skilled in the art.
  • the shutter operations main container 1 and auxiliary container 4 can be done in the simplest way using a heat-sealed lidding film. This is again at the reach of any person skilled in the art.
  • emptying the auxiliary container 4 during heating takes place in a predetermined and safe manner.
