Description

Technical field of the invention

[0001] The invention relates to a food packaging for a vegetable or dairy product, such as an individual portion of cheese, and a method of manufacturing this food packaging. Technical background

[0002] It is well known to wrap portions of cheese products using aluminum foil. It is also well known to provide rigid or semi-rigid packaging made of plastic or wax.

[0003] Known packaging includes single-dose containers formed by two half-shells made of thermoplastic material sealed along their peripheral edges. The sealing allows for complete adhesion of the peripheral edges to ensure the packaging is leak-proof. These shells are peelable, meaning that the peripheral edges can be separated by exerting traction perpendicular to the sealing plane, without causing breakage / rupture of the packaging. A known packaging is described in WO2019 / 229642.

[0004] Once the package is opened, the user can use cutlery (knife, spoon) to consume the cheese product. In the case of cheese products that are sufficiently consistent to not spill once removed from their packaging, the user uses their fingers to serve themselves. The product may eventually stick to the walls and can be peeled off with the fingers.

[0005] To avoid getting your fingers dirty, it was then suggested that such cheese products be presented on sticks to ensure consumption without touching the product once the shells are opened. The insertion of sticks complicates the packaging manufacturing process.

[0006] It has also been proposed to provide flat peelable shells that fold transversely halfway when opened, so that the first half of the shells releases half of the product and the second half of the shells remains sealed and is grippable for the user to avoid getting their fingers dirty. The disadvantage is that some of the product sometimes remains stuck in the second half of the shells.

[0007] One of the objects of the invention aims to provide food packaging, in particular for plant or dairy products, allowing the user to consume the product directly in the shell without using their fingers to grasp it, with a single opening action allowing optimal release of the product. Summary of the invention

[0008] Thus the invention relates to a food packaging of a vegetable or dairy product, such as an individual portion of cheese, comprising two shells sealed to each other along a joint plane and defining an internal cavity receiving the product, the packaging being able to be opened by peeling one shell from the other, the shells having peripheral edges extending in the joint plane and being in contact with each other, the edges being sealed to each other, said two shells corresponding to a hollow lower shell and a hollow upper shell, each shell having a tab for peeling one shell from the other, each tab extending from one of the peripheral edges in the joint plane and being integral with the corresponding shell, said tabs being superimposed on each other when the packaging is closed, each shell comprising, in the joint plane,a first end located at the level of the tabs, and a second opposite end, having formed a dosing neck for the product before sealing the shells, each shell having an axis of symmetry X passing through said two ends.,

[0009] The invention is mainly characterized in that at least the upper shell is provided with a pre-cut line proximal to the second end, at least a portion of the upper shell being capable of being separated from the lower shell by peeling the peripheral edges up to the pre-cut line, then by breaking the pre-cut line.

[0010] The main idea of ​​this invention is to provide two shells that can be easily separated initially by peeling, then by breaking at least one of the shells (in this case the upper shell) at the pre-cut line. This pre-cut line is located near the second end, that is to say at the rear part of the packaging. This line is set back as much as possible in order to provide a large opening onto the product.

[0011] According to the invention, the pre-cut line extends transversely to said X axis by connecting two lateral sides of the peripheral edge. This line extends symmetrically with respect to the X axis.

[0012] According to a possible configuration of the invention, the upper shell is broken along the entire pre-cut line.

[0013] According to another preferred configuration of the invention, the pre-cut line comprises a central folding section and two lateral breaking sections located on either side of the central folding section and joining the peripheral edge. In this case, only the lateral sections are broken at the time of opening, while the central section is folded and acts as a hinge.

[0014] The upper shell thus broken has a movable part and a part which remains fixed in the rest of the packaging.

[0015] The central folding section acts as a hinge between the moving part and the fixed part. The moving part therefore pivots relative to the fixed part.

[0016] Thanks to the breaking sections, it is possible to clear a much larger product access area than in the prior art, where there was only a folding line that defined the product access area.

[0017] So, it is no longer just half of the product that is accessible, but more than three-quarters.

[0018] The user can continue to hold the packaging by holding the lower shell and the fixed part of the upper shell together, while enjoying the product.

[0019] Peeling is traditionally done by pulling on the tab of the upper shell. Peeling is done along the peripheral edges up to the pre-cut line, then by continuing to pull on the tab, the two break sections break. Thus, in one movement the two shells are separated. The product remains in the lower shell. The peeling is gentle to avoid any sudden movement. When opening, the product does not fall, and is held by the lower shell and by the fixed part of the upper shell.

[0020] According to the different embodiments of the invention, which may be taken together or separately: the two shells have a curved shape: thus, after opening the packaging, the product is held by the conical end of the two shells. This conical shape allows the product to be extracted very easily during tasting. Unlike the prior art where half of the product was stuck by the end of the two flat shells, here the majority of the product is directly accessible, and the end of the product is easily detachable from the end of the shells. the folding section is centered and oriented substantially perpendicular to said axis of symmetry. the pre-cut line is curved: it follows the curved profile of the shells. the folding section represents less than a third of the pre-cut line. This has the effect of forming a discreet hinge, and of further increasing accessibility to the product once the packaging is opened. The lower shell is also provided with a pre-cut line, like the upper shell. Thus, the two shells are first peeled along their peripheral edges, then they are broken at the same time along the pre-cut lines which coincide at the peripheral edges. This has the effect of better opening of the packaging. The product does not fall if the two shells are broken, because it remains held in the fixed parts of the two shells. After opening the two shells by peeling, at least 80% of the product is released, without contact with the shells. Preferably, 85% of the product is released. The packaging comprises a means for gripping the product inserted between the two shells comprising: an inner part located in the internal cavity of the packaging and secured to the product, an outer part extending between the two tabs.the two shells are sealed to each other at a peelable sealing area defined by the contact area between the peripheral edges of the two shells. each rupture section crosses said sealing area. each shell has a depth smaller than its length.

[0021] The invention also relates to a method of manufacturing a package as described above, comprising the following steps: preheating two plastic films; sealing the two films along a joint plane, on a sealing area, so as to delimit two shells, the sealing area being intersected by a dosing neck intended to allow the filling of the two shells; thermoforming the shells so as to form an internal cavity, with creation of the dosing neck; dosing, via said dosing neck, of the vegetable or dairy product so as to fill the internal cavity formed between the shells; preheating then welding the edges of the neck; cutting defining the contour of the shells for individualizing the shells to their final shape.

[0022] This method also includes a step of creating the pre-cut line by pre-cutting the film to different depths along a line.

[0023] Preferably, the pre-cutting is carried out on the flat film, before the preheating step. Brief description of the figures

[0024] Other characteristics and advantages of the invention will appear during the reading of the detailed description which follows for the understanding of which reference will be made to the appended drawings in which: [ Fig. 1 ] there [ Fig. 1 ] is a top view of the closed package according to a first configuration of the invention; [ Fig.2 ] there [ Fig.2 ] is a perspective view of the front of the open package according to the first configuration of the invention; [ Fig.3 ] there [ Fig.3 ] is a perspective view of the rear of the open package according to the first configuration of the invention; [ Fig.4 ] there [ Fig.4 ] is a top view of the closed package according to a second configuration of the invention; [ Fig.5 ] there [ Fig.5 ] is a perspective view of the front of the open package according to the second configuration of the invention; [ Fig.6 ] there [ Fig.6] is a perspective view of the rear of the open package according to the second configuration of the invention; [ Fig.7 ] there [ Fig.7 ] represents a reel of plastic film where pre-cuts are made; [ Fig.8 ] there [ Fig.8 ] represents a pre-cut made in the thickness of the plastic film; [ Fig.9 ] there [ Fig.9 ] represents a variant of pre-cutting made in the thickness of the plastic film. Detailed description of the invention

[0025] In the remainder of the description, we will adopt in a non-limiting manner - and without reference to Earth's gravity - vertical, longitudinal, and transverse orientations indicated by the trihedron "X, Y, Z" as illustrated in the figures 1 And 4 We also define a horizontal plane which extends longitudinally and transversely, and which will be called the joint plane P.

[0026] The description below applies to both configurations. The first configuration shows packaging without a means of gripping the product, while the second configuration shows packaging with a means of gripping the product.

[0027] THE figures 1 And 4 illustrate a food packaging 1 of a vegetable or dairy product, such as an individual portion of cheese, seen from above and closed. This packaging 1 has an axis of symmetry X, corresponding to the X axis of the previously defined trihedron.

[0028] Package 1 consists mainly of two shells 2, 3 sealed to each other along the joint plane. The two shells 2, 3 are sealed to each other at a peelable sealing area.

[0029] These two shells 2, 3 define an internal cavity which receives the vegetable or dairy product.

[0030] Package 1 is capable of being opened by peeling one shell away from the other.

[0031] THE figures 2 , 3 , 5 , 6 illustrate the packaging 1 in the open position. In fact, the two shells 2, 3 have been separated from each other by peeling. The vegetable or dairy product 4 can clearly be seen between the two shells 2, 3.

[0032] By plant or dairy product 4, we mean a product 4 that is sufficiently consistent not to spread once removed from its packaging 1. In other words, the plant or dairy product 4 is not in liquid form under normal temperature and pressure conditions. The product 4 is therefore solid, or semi-solid, that is to say, sufficiently viscous to remain in a lump.

[0033] The vegetable or dairy product 4 takes the shape of the internal cavity. It substantially fills the entire internal cavity of the closed package 1.

[0034] More precisely, the two shells 2, 3 correspond to a first shell 2, which we will call for convenience the “upper shell”, and a second shell 3, which we will call for convenience the “lower shell”.

[0035] Both hulls 2, 3 are flexible or semi-rigid.

[0036] In the illustrated configurations, the two shells 2, 3 have identical shapes, so that the internal space has a volume equally distributed between the two shells 2, 3.

[0037] In other configurations not illustrated and forming part of the invention, the two shells 2, 3 are in different shapes. The internal space then has a volume unequally distributed between the two shells 2, 3. Preferably, the lower shell 3 forms between a third of the overall volume and half of the overall volume of said internal space.

[0038] In the illustrated configurations, the two shells 2, 3 have the same cup shape. The cups have rims 5, 6 which form circular collars. Thus, each shell 2, 3 has a peripheral rim 5, 6 which extends into the joint plane P.

[0039] When the package 1 is closed, the two peripheral edges 5, 6 are superimposed and sealed to each other. They thus define the sealing range. This sealing range corresponds to a closed loop, which makes it possible to seal the internal cavity from the external environment.

[0040] The two shells 2, 3 are advantageously made of plastic. This may be recycled plastic and / or recyclable plastic. For example, the plastic material used to manufacture these two shells 2, 3 may comprise several layers. It may be a multilayer of different polymers.

[0041] The material could, for example, have a polypropylene base material known for its natural hinge effect.

[0042] The peel force value will be advantageously adaptable; it will preferably be between 4 and 25 Newtons.

[0043] In the configurations shown, each shell 2, 3 has a depth smaller than its length. The depth is measured in the plane defined by the X and Z axes, and therefore corresponds to the distance between the bottom of the shell 2, 3 and the top of the shell 2, 3 (i.e. the level of the peripheral edge 5, 6 in the joint plane P). The length is measured in the plane defined by the X and Y axes, therefore in the joint plane P, and corresponds to the maximum distance between two opposite points of the peripheral edge 5, 6. If the shell 2, 3 has a round section, these two points will be diametrically opposed.

[0044] With a depth smaller than the length, this means that the product 4 is not sunk into a hull, but is instead widely accessible.

[0045] For example, shells 2, 3 have a circular shape.

[0046] Preferably, the shells 2, 3 are hollow, with a domed shape. This has an advantage which will be described later in the description.

[0047] The two shells 2, 3 are sealed to each other at their peripheral edges 5, 6 placed in contact with each other. There is therefore a contact zone between the peripheral edges 5, 6 of the two shells 2, 3, defining the sealing range.

[0048] For each shell 2, 3, the peripheral edge 5, 6 extends towards the outside of the shell 2, 3 by a peeling tab 7, 8. This tab 7, 8 extends along the axis X in the joint plane P, and is integral with the shell 2.

[0049] In the illustrated case, this tab 7, 8 has the shape of a rounded ear.

[0050] This tab 7, 8 is flat so as to be easily pinched between two fingers of a user. This tab 7, 8 is also sufficiently extended in the joint plane P, to have sufficient grip for the user's fingers.

[0051] The two tabs 7, 8 are superimposed when the packaging 1 is closed.

[0052] Preferably, they have an identical shape.

[0053] The tabs 7, 8 are not sealed together, so that the user can easily take hold of them to pull on them and open the packaging 1.

[0054] Opposite the tabs 7, 8, on the X axis, is the dosing neck 15 through which the product is injected into the cavity at the time of manufacture.

[0055] According to the invention, at least the upper shell 2 has a pre-cut line 11 which extends substantially transversely, therefore perpendicular to the axis X, from one side of the shell 2 to the other. This pre-cut line 11 joins the peripheral rim 5 at the level of the two lateral sides.

[0056] This pre-cutting line 11 is divided into three sections, namely: a central folding section 11b two lateral breaking sections 11a, 11c, on either side of the central section 11b.

[0057] The three sections form a single continuous line.

[0058] Preferably, this line is slightly curved. The curve is directed towards the dosing neck 15.

[0059] The pre-cut line 11 is made in the vicinity of the dosing neck 15, on the upper shell 2.

[0060] It can be considered that each shell 2, 3 has a front part with a first end located at the level of the tabs 7, 8, and a rear part with a second opposite end located at the level of the dosing neck 15. The axis of symmetry X passes through the two ends.

[0061] So the pre-cut line 11 is located in the rear part of the hull. It is therefore proximal to the second end.

[0062] More precisely, the folding section 11b is proximal to the second end and is perpendicular to the X axis.

[0063] More precisely, the folding section 11b is located more than two-thirds of the length of the hull.

[0064] For example, for a hull with a length of 43mm (including edges), the pre-cut line is located at 35.5mm, i.e. 7.5mm from the second end.

[0065] Each breaking section 11a, 11c starts from the folding section 11b and joins the peripheral edge 5, and crosses the entire width of the peripheral edge 5 up to the edge. Thus, each breaking section 11a, 11c crosses the sealing area.

[0066] As a result, when the user wishes to open the packaging 1, he pulls on the tab 8 of the upper shell 2, which causes the peeling of the shells 2, 3 up to the breaking sections 11a, 11c which break under the tensile force. The peeling is thus stopped, and the upper shell 2 is divided into two parts, namely: a mobile part 2a which is moved away from the product 4, and a fixed part 2b which remains in place, in contact with the product 4.

[0067] The two parts 2a, 2b remain secured to each other via the central folding section 11b which has not broken. This folding section 11b acts as a hinge. Thus, the movable part 2a can pivot relative to the fixed part 2b.

[0068] All of the product 4 which was in contact with the moving part 2a is thus freely accessible.

[0069] According to a possible example of the invention, the lower shell 3 has no pre-cut, and continues to support the product 4. The movable part 2a of the upper shell 2 is large enough to correctly release the product 4, and the consumer can come and eat the product directly in the lower shell 3. If necessary, he can press on the bottom of the lower shell 3 to make the product detach from the wall and raise it.

[0070] According to another possible example of the invention, as illustrated, the lower shell 3 also has a pre-cut line 11.

[0071] Preferably, it is identical to that of the upper shell 2. In this case, the orientation of the shells no longer matters. The terms "lower" and "upper" are just mentioned for the sake of clarity in order to distinguish the two shells. They could be replaced by the terms "first" and "second".

[0072] Thus, when the user pulls on a tab 7, 8, the peeling of the shells 2, 3 occurs until the upper shell 2 and the lower shell 3 break at the same time.

[0073] Product 4 is even better released, and only a small part remains held in the two fixed parts 2b, 3b of the shells 2, 3.

[0074] The two remaining fixed parts 2b, 3b form a conical space accommodating the end of the product 4. This conical space comes from the domed shape of the shells 2, 3. This conical space has the effect of allowing easy removal of the end of the product. Indeed, if the shells were flat, the space would not be conical, and the end of the product could remain stuck in the space. The flared, conical shape makes it possible to extract, or "unmold" in a way, the end of the product with ease.

[0075] Preferably, the fold line 11b represents less than one third of the continuous curve. The narrower the hinge, the easier the access to the product 4.

[0076] Preferably, at least 80% of the product is released when both shells 2, 3 are ruptured.

[0077] Preferably, 85% of the product is released from its packaging 1.

[0078] The remaining 15% housed in the fixed parts 2b, 3b is easily removable.

[0079] The user can thus taste the product 4 without having to touch it with his fingers.

[0080] The pre-cut line 11 is made in such a way that the shells 2, 3 break as soon as the peripheral edges 5, 6 are peeled at the passage of the rupture sections 11a, 11c. Thus, the downstream part of the peripheral edges 5, 6, that is to say from the rupture sections 11a, 11c to the dosing neck 15, remains sealed once the packaging 1 is opened. This is not problematic, because the remaining part of the product is easily extractable as seen previously, unlike the prior art.

[0081] In the first configuration presented to the figures 1 to 3 , there are no means of gripping the product.

[0082] In the second configuration presented to the figures 4 to 6 , there is a means of gripping 10 of the product which is added. This is the only difference between the two configurations.

[0083] In this case, the gripping means 10 may consist of a stick, which is introduced between the shells 2, 3 at the time of manufacture and before dosing the product.

[0084] The gripping means 10 has a part housed in the internal cavity of the shells 2, 3, and on which the product 4 is secured, and an external part which comes out of the shells 2, 3 and is located between the two tabs 7, 8.

[0085] The peripheral edges 5, 6 are sealed on the gripping means 10 to ensure the sealing of the internal cavity, when the packaging 1 is closed.

[0086] The tabs 7, 8 are not sealed to the gripping means 10, so that the user can easily move each tab 7, 8 away from the gripping means 10 and pull on it to open the packaging 1 while holding the gripping means 10.

[0087] Finally, whatever the configuration chosen, the user can taste the product 4 without having to touch it with his fingers.

[0088] The invention also relates to a method for manufacturing a food packaging 1, in particular for a vegetable or dairy product 4, for example the packaging 1 described above, from at least one reel of plastic film 12 and which comprises the following steps: preheating two films 12 made of plastic material; sealing the two films 12 along a joint plane, on a sealing area, so as to delimit two shells 2, 3, the sealing area being intersected by a dosing neck 15 intended to allow the filling of the two shells 2, 3; thermoforming the shells 2, 3, so as to form an internal cavity, with creation of the dosing neck 15; dosing, via said dosing neck 15, of the vegetable or dairy product 4 so as to fill the internal cavity formed between the shells 2, 3; preheating then welding the edges of the neck 15; cutting defining the contour of the shells 2, 3 for individualizing the shells to their final shape (as illustrated by the dotted lines in [ Fig.7 ]).

[0089] These steps are preferably successive, but can also be carried out in another order.

[0090] This method comprises a step of creating the pre-cutting line 11 by pre-cutting the film 12 to different depths along a line.

[0091] The pre-cut line 11 can be made on a flat film 12 as illustrated in [ Fig.7 ], or on a formed film 12, or on the formed shells, on the formed or welded necks. These pre-cutting lines 11 are separated by a pitch P.

[0092] For the creation of pre-cutting lines 11 the technologies used may vary and be mechanical (knife), electromechanical (ultrasound), or laser, or any other scarifying process.

[0093] Each pre-cut line 11 can be straight or follow a path adapted to the best opening functionality required. Here the line is straight at its two ends, which coincide with the peripheral edges, and rounded between the ends to approach the back of the package.

[0094] Preferably, the pre-cutting line 11 is made on the flat film 12, before the preheating step. When the pre-cutting is made on the flat film 12, account is taken of the future thinning of the film 12 due to the stretching carried out during the thermoforming of the shells 2, 3. This makes it possible to avoid the risk of breaking the thinned film 12 at the pre-cutting line 11, before the user handles the packaging 1 for opening.

[0095] The adjustment of the pre-cuts on the continuous or interrupted aspect as well as on the depth is defined by the programming of the pre-cutting tools. We can therefore adjust the place where we pre-cut, on what length and depth. To do this, we can take a reference on the shape of the shells or on the graphics carried by the film.

[0096] Depending on the depth of the pre-cut, we obtain more or less fragile areas, therefore tending to break more or less easily, or simply tending to bend. The greater the depth, the more easily the section will break.

[0097] To obtain the folding section 11b, either a shallow pre-cut is made, or a discontinuity is created in the pre-cut line.

[0098] As illustrated in [ Fig.8 ], the pre-cutting line 11 comprises two deep lateral zones corresponding to the breaking sections 11a, 11c, and a less deep central zone corresponding to the folding section 11b.

[0099] As illustrated in [ Fig.9], the fracture sections 11a, 11c may comprise a very deep zone at the peripheral edges 5, 6 (where the thickness is greater once the shells are formed), followed by a less deep zone at the bulging part of the shell 2, 3 (where the thickness is thinner once the shells are formed). And the central bending section 11b is intact, and does not have a pre-cut. There is therefore a discontinuity in the pre-cut at the central section 11b.

[0100] When the user opens the shells, the very deep area is broken first, and the breakage easily spreads to the shallower area.

[0101] The pre-cutting line 11 can also be carried out in two stages, with the creation of the very deep zones upstream of the preheating step, and the creation of the less deep zones after the forming step or the dosing step.

[0102] To form the lower shell 3 and the upper shell 2, the method can use two films 12 from two different reels subsequently superimposed or a single reel folded on itself which provides a very precise level of registration between the two printed faces. The centering of the shells is ensured at the forming station where the two parts are obtained simultaneously and centered, before the sealing step. Preferably, the films 12 are preheated before the sealing step.

[0103] Preferably, sealing is achieved by heat sealing.

[0104] The seal is used to hermetically close the packaging 1. The seal allows a controlled and adjustable opening whose force can be measured (Peel Force).

[0105] The welding of the dosing neck 15, or other parts of the packaging 1, can be carried out by heat welding. The welding gives a definitive assembly which is impossible to separate and therefore to open, except by destroying it.
