Definitions
- the present invention relates to a packaging for a food product.
- Portion packaging is conventionally made with a thin aluminum film, folded to form an open container in which the hot cheese is dosed. An aluminum cap is then placed on the cheese, and the whole is sealed. These portions have an easy opening system achieved by means of a plastic tear guide strip glued into the package before shaping.
- Such portion packs are economical to produce and provide a relative seal allowing the products mentioned to obtain satisfactory storage under difficult logistical conditions.
- leaks have a negative impact on the preservation of the product. Indeed, the loss of water during storage modifies the texture of the product and requires an overdose in packaging. Leaks also allow oxygen into the packaging and limit the shelf life by rancidity of the product. The flow of serum and the proximity of the cheese to the external environment can cause the appearance of mold on the outside of the packaging, presenting an unpleasant appearance for the consumer even if the product is not altered in the packaging. .
- JP H07-101463 describes a package formed from a sheet sealed on itself containing, for example, sliced cheese. However, after filling the packaging with hot cheese in a liquid state, then sealing the packaging to reclose it, the packaging containing the cheese must be shaped by passing between two rollers and cooled to form slices, which has the effect of slowing down the production rate.
- WO 2011/058237 describes a foldable packaging of a portionable food product, comprising a side strip having two longitudinal edges connected by two end edges, and having at least one curvature and / or one fold to provide storage space for the product food, and a seal peelably attached to the end edges.
- such packaging requires the side band and the cover to be produced separately, and to assemble them in a peelable manner by at least three successive seals, which prove to be complex to implement.
- the packaging thus formed has a large sealing surface increasing the risks of leakage.
- FR 2957062 describes a packaging of the aforementioned type in particular of a portion of cheese, the packaging comprising a bottom and side walls folded perpendicularly to the bottom and forming with the bottom an airtight cavity, the packaging further comprising a cover integral with a side wall folded down and sealed on the fixing flats of the other side walls.
- the blank needed to make this unit-by-unit product packaging has many cutouts that generate significant material losses, and mechanical complexity in forming the packaging.

- the invention provides a volumizing of the packaging, even when empty, from a single sheet. It is thus possible to use the packaging directly as a mold for a food product which would be deposited in liquid form in the packaging before it is closed, which allows production savings by avoiding a step of shaping the food product. before the packaging stage and thus maintaining high production rates.
- Another advantage of the invention relates to hygiene and preservation.
- the product By pouring the product directly into the packaging, it is only slightly exposed to the ambient air, limiting the risk of contamination. If in addition the product is poured at a temperature above the pasteurization temperature, between 60 ° C and 90 ° C at atmospheric pressure, the preservation is further improved.

- the longitudinal losses 30, 31, 32, 33, transverse 42, 43, 44, 53, 62, 63, 64, 65 and additional 45, 46, 47, 48, 49, 50, 51, 52 , 53 are for example produced by removing part of the sheet 10 in its thickness, via a half-cut precut obtained by blades or by laser treatment.
- the fold weakening is partly merged with the tear guide strips 60, 61 in the form of a weakening of the sheet 10, the opening being according to the folding weakens.
- the realization of such weakenings makes it possible to reduce the rigidity of the sheet along precise lines to allow its folding during the shaping of the sheet 10 before filling and the finalization of its shaping after filling.
- a part of the sheet 10 is for example cut on one of the longitudinal edges 38, 39 of the sheet 10 to create the tab 56.
- the tab 56 is made by a combination of cutting and folding.
- two straight cuts are formed in the sheet perpendicular to the edge on which the tab is made, and the sheet is folded back on itself at 45 ° outside each cut to form a point.
- the part of the sheet folded to form the tab is sealed and glued to prevent the tab from unfolding.
- This substep 89 can be carried out before, during or after the substep 87 of forming the tear guide strips 60, 61 and the substep 88 of forming the longitudinal weakenings 30, 31, 32, 33, transverse 42. , 43, 44, 53, 62, 63, 64, 65 and additional 45, 46, 47, 48, 49, 50, 51, 52, 53.
- the formation of the tongue 56 is obtained by simple cutting in the sheet 10, or by a combination of one or more cutouts and one or more folds.
- the primers 68, 69 are further formed by simple cutting in the sheet 10, or by a “half-flesh” cut.
- the formation of the primers 68, 69 can be carried out during the substep 88 of formation of the longitudinal weakenings 30, 31, 32, 33, transverse 42, 43, 44, 53, 62, 63, 64, 65 and additional 45, 46 , 47, 48, 49, 50, 51, 52, 53 or during the substep 89 of making the tab 56.
- each sheet 10 is folded back on itself following the transverse weaknesses 42, 43, 44 to form a front face 100, a rear face 102, and two transverse side faces 104, 106 with an angle of 90 ° between two consecutive faces 100, 102, 104, 106.
- the sealing hem 67 is folded as shown in Figure 5 along the transverse weakening 66 connecting the hem 67 to the longitudinal panel 37 furthest from the region of. end 22, towards the outside of the package 12; 12 'so that the folding of the sheet 10 on itself following the transverse weaknesses 42, 43, 44 brings the strip 54 and the sealing hem 67 opposite each other.
- the tongue 56 and the strip 54 are folded over the rear face 102 along the transverse weakening 53.
- the blank 70 of a plurality of sheets 10 thus folded forms a tube 112 of rectangular section shown in Figure 4.
- the tongue 56 projects longitudinally from the transverse seal 110.
- forming equipment of the gooseneck type is for example used, the outlet of which has a rectangular section and is extended by a pipe of section identical to the outlet section of the tube. cheese equipment.
- the equipment for making the packaging 12; 12 includes counterparts making it possible to maintain the geometry of the tube 112 from the outside, by pressing it against the pipe.
- the counterparts are typically simple plates fitted snugly around tube 112, or drive rollers.
- the strip 54 is sealed to the sealing hem 67 as and when packages 12 are produced by the process.
- the seal is of the “flesh-to-flesh” type.
- the sealing is for example carried out by heating or ultrasonic rollers applied to the tube 112, or by heating or ultrasonic bars applied to the tube 112.
- the strip 54 when sealed forms a transverse seal 110 of the package 12; 12 ’.
- the transverse seal 110 is peelable or tearable.
- the sealing hem 67 prevents the transverse edge 41 of the sheet 10 opposite the end region 22 from coming into direct contact with the food product P when the sheet 10 is folded back.
- This geometry is particularly suitable for materials which cannot be directly brought into contact with the product, in particular materials based on paper or cardboard.
- the transverse seal 110 is peelable, as shown in FIG. 9, this sealing must be carried out with precise settings.
- a tear-off transverse seal 110 as shown in Figure 12 is obtained using primers 68, 69.
- the strip 54 is sealed to the rear face 102.
- This seal is of the “leather-flesh” type giving a seal of the peelable type so as to obtain a really facilitated opening at the end of the journey.
- the sealing is for example carried out by heating or ultrasonic rollers applied to the tube 112, or by heating or ultrasonic bars applied to the tube 112.
- the sheet 10 must not, in its thickness, exhibit any sensitivity to the food product P contained in the package 12. In fact, on the transverse edge 41 of the sheet 10 opposite to the end region 22, all of the constituent materials of the sheet 10 are found bare and therefore exposed to direct contact with the food product P. To remedy this, this example requires either to use a naturally resistant material, or to cover this area where the product food P is exposed with a sealing layer and optionally a barrier to water and gases as defined above.
- This problem is particularly to be taken into account for materials sensitive to water and oil, in particular paper and cardboard.
- the sheet 10 is sealed longitudinally in the vicinity of one of the two longitudinal edges 39 to form a bottom longitudinal seal 114 as shown in Figure 6.

- the forming equipment In order to be able to carry out the filling, the forming equipment is vertical geometry, and its upstream end is located above its downstream end.
- upstream end is meant the end located upstream of the forming operation.
- the assay is preferably carried out at temperatures between 20 ° C and 90 ° C, preferably between 30 ° C and 80 ° C.
- the food product P during the dosage is in the liquid or viscous state so as to occupy the entire interior cavity 122.
- the pipe is lowered at the time of dosing and raised at the end of dosing so that the level of food product P discharged is closest to the maximum level reached after dosing and to avoid the risk of splashing on tube 112 and forming equipment.
- the dosage of food product P must be precise in volume.
