Definitions
- WO 02/060223 disclose such a set.
- a problem may be related to the quality of cooking.
- Another problem may be related to the food product that is desired to cook as expected (for example both bleeding and golden, if it is a red meat).
- Another problem may be related to the knowledge that it may be useful for the consumer to have the moment when the food product contained in the set will be considered ready to eat.
- the film be stretchable and the outer packaging designed to counteract the deformation by a rigid wall, during heating of said assembly in the enclosure; this outer packaging is also provided with a means sensitive to heat and / or pressure and holds the shutter closed towards the end of the heating, ensuring a confined heating up to a certain threshold of temperature and / or pressure, before releasing the opening of said flap.
- this inner packaging comprises a container in the bottom of which will be (will have been) placed the food product and which will be closed by said stretch film, which will be vacuum plated, stretched, around the food product and along the bottom and side walls of the tray, at least before heating.
- the "stretch film” will be a film known in the field as a “superior film”.
- the means which keeps the shutter closed is adapted to be broken at heating, substantially when the pressure is maximum.
- this moment will be located shortly before or during a loosening of said stretch film, or shortly after the deflation of this unsealed film.
- the assembly 1 is adapted to be heated in a heating chamber 3a of a microwave oven 3.
- the assembly 1 comprises an inner packaging 7 initially closed, containing the product 5 to be heated and / or cooked, and an outer packaging 9 (90 figure 3 ) at least partially doubling the inner packaging.
- the product 5 is typically a fresh product, possibly already slightly golden or precooked, such as a meat or a fish to cook or finish cooking.
- the inner packaging 7 is closed by a plastic stretch film 11, of course quality (therefore compatible) food.
- This film may in particular be a coextruded film adapted to the packaging of fresh or frozen products, especially under vacuum. Frozen or fresh products or those that can be fully or partially pre-cooked are also concerned.
- DARFRESH TM film from CRYOVAC.
- the inner packaging 7 will advantageously comprise a container 15 in the bottom of which the food product 5 has been placed here and which is thus closed by the film 11.
- this film 11 was plated around the product 5 and over the bottom 15a of the tray. It is sealingly attached to the support 15, preferably on the upper peripheral rim 15b thereof.
- This wall 9a belongs to the outer packaging considered, 9 figure 1 which ensures a maintenance of said wall above the film for at least a portion of the time during which an internal increase in the pressure in the closed inner package 7, following placement and heating of said assembly in the enclosure 3a , will create a deformation of the film to the outside, this deformation being thwarted by the wall 9a.
- This wall 9a is less deformable than the film 11 at the same pressure.
- the wall 9a is held in place since the outer packaging 9 (identified 900 fig.4 ) is in the form of a sheath provided with at least one opening 9b on at least one of its sides.
- the inner package 7 can be slid into, and removed from, the sheath, one of the side walls is thus defined by the aforementioned retaining wall.
- the sheath in question is in the form of a box completely enclosing the inner package 7 and which is provided with at least one movable flap 13a through which the opening 9b and thus the box can be opened and closed.
- the wall 9a will extend substantially parallel and at the level of the open upper surface 19 of the tray (top of the side walls), so as to act on the deformation of the film towards the outside when the latter substantially reaches this level , heating.
- a flat, rigid wall belonging to a parallelepiped box will be suitable.
- this retaining wall will comprise, or be made of, cardboard.
- cardboard a material that is suitable for carrying a message for example advertising (printing or otherwise).
- shutter (s) closed (s) we will be able, during the heating of the complete assembly in the enclosure, ensure real containment inside the outer packaging.
- the shutter be kept closed by a means of closure 17 adapted to allow the flap 13a to open by local delamination of the outer packaging material.
- each movable flap concerned is retained closed on this packaging, as figure 3 by a strip of continuous or discontinuous adhesive existing between the flap and a zone of the outer packaging that the latter covers, closed.
- the reference 17a figure 5 shows a strip of discontinuous glue.
- the or each movable flap will preferably be folded and closed on the outer package, over the wall 9c opposite to said retaining wall 9a.
- this wall 9c will be the bottom wall of the sheath, that is to say the one by which the said conditioned assembly is placed, thus avoiding the user being tempted to open it before heating.
- the outer packaging comprises two said openings, on two opposite sides, each of which can be closed and opened by a movable flap, here folded, such as 13a, 13b figure 4 , one of them being preferably retained closed on an area of the considered package with a lower mechanical strength than that of the other component.
- a movable flap here folded, such as 13a, 13b figure 4 , one of them being preferably retained closed on an area of the considered package with a lower mechanical strength than that of the other component.
- Figure 6 21a, 21b two pre-cuts made through part of the thickness of the wall 9c of the bottom of the package 9, facing the flap 13a to control its control opening.
- This is a solution for the abovementioned half-flesh weakening which must favor the controlled opening here of the flap 13a.
- 23a indicates the direction of the fibers of the board, on the schematic plate: perpendicular to the direction 23b which passes through the two opposite flaps 13a, 13b.
- the package will preferably be in one piece, cut as appropriate (see illustration where the dashed lines such as mark the areas of folds made by thin lines of surface cuts).
- FIG 5 schematically this, in connection with the use of the box 9.
- this deflation will be achieved by local loosening of the film at a location on the periphery of the blister pack 15.
- the closed means for holding one of the flaps (such as 13a fig.1 ) is substantially broken when the pressure is maximum shortly before or during loosening of the film, or shortly after deflation of the unsealed film.
- the opening of the flap 13a will intervene shortly before or during the loosening of the film.
- the closed holding means of the outer package until towards the end of the heating will be favorably sensitive to the heat and / or the inflation pressure of the film 11 and will therefore perform its function of closing and / or confining to a certain threshold of temperature and / or pressure.
- a steam exhaust means other than such a glued flap could be suitable.
- a valve as is already known, could be used on the outer package.
- the heating in the enclosure 3a may last 50 to 70s, at 900W approximately.
- the upper film 11 could be sealed to a rigid or semi-rigid lower structure having a shape other than a tray, such as a flat plate.
- the package 7 contains a means 100 for absorbing exudates from the food product 5 and a rigid or semi-rigid film container 15 having a bottom wall 150 against an inner face 151 of which the means 100 is disposed.
- the absorber means is adapted to be shaped in the shape of at least a portion of said inner face of the wall that it thus marries, covering it.
- This means 100 is therefore a sheet which serves as a blotter, with absorption capacity of flowing products, liquid or semi-liquid.
- plating This airtight plating (known as "plaxage") results from the air gap established under the film 11.
- the exudate absorbing means adheres to the inner face 151 of the wall it covers.
- the exudate absorber means 100 and said inner face 151 will be favorably dark in color. , preferably black and shiny, and will be adapted so that the absorber means is thus linked by lamination with this inner face.
- this inner face 151 and here the entire bottom wall, has depressions 30 and bumps 28 substantially wedge blotter 100.
