• the present invention relates to a disposable internal protection device 1 intended to be put in place, according to F5 in FIG. 1, inside the enclosure of an oven 2.
• This disposable device 1 is essentially constituted by a folding box 3.
• This box 3 is shaped, as can be seen clearly in FIGS. 3, 8 and 9.
• the latter 3 has a substantially parallelepiped shape having two faces which have been deleted. These two faces are the upper face and the front face. Therefore, the box 3 consists of a rear wall 7, two side walls 5 and 6 and a bottom wall 4. According to a first embodiment shown in Figures 1 and 2, these walls are secured the to each other and form a one-piece assembly.
• the folding box 3 consists of two parts 9 and 10.
• the first part 9 consists of the joining by means of fixing of the public domain, of three panels constituting, on the one hand, the side walls 5 and 6 and, on the other hand, the rear wall 7.
• This fixing can be produced either by gluing, welding or clinching 22, as shown in FIG. 12.
• the second part is formed by the lower wall 4 which, as seen in FIG. 6 in side view, is constituted by a tray 4.
• this tray can consist of a dish that can be reused. In this case, it will only be necessary to replace the other three walls of the disposable device 1.
• the use of a dish, as a tray 4 can allow storage during the sale of the device 1 a maximum of first parts 9 consisting of side walls 5, 6 and rear 7 disposable.
• the first part 9 of the box 3 it consists of a single element folded on two levels to constitute, on the one hand, the rear wall 7, on the other hand, the side wall right 5 and the left side wall 6. This is well represented in FIG. 7. Of course, this second part will always cooperate with a second part 10, as shown in FIGS. 5 and 6.
• grooves are present at the level of the set of walls to increase the rigidity of the set.
• the side walls 5 and 6 have horizontal grooves 11 and 12 which are parallel to the tray 4, when the box 3 is shaped. These grooves 11 and 12 allow the installation, inside the device 1 itself inside the oven 2, of a grid 13 of said oven 2, shown in FIG. 1.
• the grid 13 is however not put in place to allow its positioning inside the disposable device 1, but under this device 1 in order to create a space between the hearth of the oven 2 and the bottom wall 4 of said disposable device 1.
• the tray 4 according to Figures 5 and 6 also have ribs 23 which increase the rigidity of this element.
• the rear wall 7 being structurally integral with the side walls 5 and 6, it is necessary that the excess material due to the presence of the grooves 12, at the side walls 5 and 6, is absorbed. Therefore, folds 24 are produced which allow these lateral grooves 12 to be absorbed and further increase the rigidity of the rear wall 7. All of the walls 4 to 7 always have the same references, this in order to facilitate the understanding of the different embodiments of the present invention.
• this anti-drip lift 8 has a V 21 shape. , in cross section. This improves the rigidity of this lift 8 and also gives it a spacer function between the two side walls 5 and 6.

• This has a special structure shown in FIG. 11 and which is made up of a set of awnings 17.
• the part in front of the plane is that which is located inside the disposable device 1. It is therefore easy to understand that any liquid or liquid cooking substance that would flow along the inner face of the rear wall 7 could not pass outside said dispositi dispositi 1 due to the fact that the inclination of the awnings 17 prevents the external flow of said fluid.
• the walls 4 to 7 have, at an adequate predetermined position, a slot allowing the rotisserie of the oven 2 to be put in place.
• FIGS. 4, 7, 8 and 9 we note the presence at the level of the rear wall 7 of a transparent part 18 whose predetermined arrangement is adequate to allow juxtaposition relative to the interior lamp of the oven 2. According to the FIG. 8, it is possible to visualize all of the air movements that can occur within the disposable device 1. It is at this level that the innovation and the importance of the invention can be seen in relation to the state of the art. It is noted that the hot air can, by convection, penetrate inside the concavity of the disposable device 1 at three very specific places.
• the hot air can penetrate by passing over the rear wall 7.
• the hot air can also pass between the bottom wall 4 and the bottom of the oven.
• the hot air can also pass between the bottom wall 4 and the bottom of the oven.
• a plurality of holes 14 at the level of the wall 7 is made; of course, these holes 14 could be located at another location or on other walls.
• the box 3 may optionally include a transparent front wall 19. However, it is necessary that the air flow according to F2 can always be achieved, therefore a free space 20, located between the ascent
