Description

Technical Field

[0001] The present invention relates to the technical field of food products, in particular so-called take-away products. More specifically, the present invention relates to a packaging device capable of transporting different types of food products from their place of production to their place of consumption. For the purposes of the present invention, a first type of food product is referred to as solid, for example because it comprises a food dough, such as in particular pizza. A second type of food product is referred to as non-solid, for example because it has a liquid or pasty consistency. Background Art

[0002] Food products in general constitute a sizeable industrial market. Traditionally, these products are consumed on site in restaurants. There is also a demand for so-called "fast" consumption of these products. In this fast consumption, the purchaser usually takes the food product with him in order to consume it in public places, on transport or even on the street.

[0003] Another possibility, more specifically the object of the present invention, consists in transporting the food products from their place of production to the place where they are consumed, usually to the home of the consumer. In this case, the customer can go directly to the place of production in order to collect the food products themselves and then take them home. Alternatively, the consumer can choose to have the food products delivered directly to the consumer's home by a courier.

[0004] In both cases, there are different types of containers used to transport food products. Thus, in the case of pizza, individual cardboard boxes are used, which are usually square in shape. In the case of food products with a fluid consistency, these are received in cups or jars, which can also be made of cardboard or even so-called "kraft paper".

[0005] The various solutions currently available on the market have a number of disadvantages. Firstly, depending on the nature of the food product to be transported, a wide variety of container types need to be available. This tends to make the job of the restaurateur more complicated while increasing the overall cost.

[0006] Furthermore, the various containers used are usually single-use, which means they are not recyclable. In fact, these containers are often soiled with ingredients from different food products. In this case, due to the very large number of containers in circulation, a large amount of waste is generated due to lack of recycling, which leads to serious ecological problems.

[0007] Furthermore, it has been observed that conventional containers do not have very satisfactory insulating capabilities. In this case, the food products may not maintain adequate temperatures when they arrive at the consumer's home. It is of course possible to reheat these products afterwards: however, this means a delay in consumption and, if this reheating is carried out in a microwave, the taste quality deteriorates.

[0008] We will cite US2 828 903, which describes a disposable container having insulating properties that allows hot or cold foods to be kept at the proper temperature. The container comprises an outer container made of cardboard, the inner wall of which is coated with an insulating material. An inner container made of the same material is housed in the outer container using a centering device.

[0009] The solution described in this document does not offer any improvement on the problem posed. In fact, the container described above is disposable and absolutely unsuitable for repeated use. Moreover, the centering device forms a separate component and can therefore be lost during use. Finally, this document does not relate to the packaging of food products, such as pizza, to which the present invention is more particularly directed.

[0010] Finally, we shall mention Belgian document BE 1014682, which describes a crude solution which is generally similar to that proposed in the above-mentioned US patent.

[0011] In view of the above situation, an object of the present invention is to at least partially remedy the above-mentioned shortcomings of the prior art.

[0012] Another object of the present invention is to provide a device that is versatile in that it can easily package and transport different types of food products, in particular solid and non-solid food products as described above.

[0013] Another object of the present invention is to provide a device that can be assembled quickly and intuitively without prolonging the time of filling with food products at the production site.

[0014] Another object of the present invention is to propose a device suitable for recycling, that is to say suitable for packaging and transporting large quantities of continuous food products.

[0015] Another object of the present invention is to propose a packaging device that ensures effective thermal insulation, thereby keeping the food product at an optimal consumption temperature. Summary of the invention

[0016] According to the invention, at least one of the above-mentioned objects is achieved by a packaging device (I; II; III) suitable for packaging different types of food products, in particular food products of solid and non-solid type, comprising a bottom part (1; 101; 201) and a cover (2; 102; 202) movable relative to the bottom part between a closed position and an access position, wherein in the closed position the bottom part and the cover together define an inner volume (V), the access position opening onto the inner volume,

[0017] The device also comprises a bottom plate (4; 104; 204) and a bell-shaped member (6; 106; 206), the height (H6) of the bell-shaped member being substantially higher than the height of the bottom plate,

[0018] The bottom plate and the bell-shaped piece are capable of forming a substantially closed receiving housing (3, 3'; 103, 103'; 203, 203') which is accommodated in the inner space,

[0019] The receiving housing is capable of successively receiving different types of food products,

[0020] The base plate and the bell can adopt two different configurations, namely

[0021] - a first configuration in which the base plate rests on the bottom element so that the casing (3; 103; 203) can receive a solid food product, such as a pizza (P),

[0022] - A second configuration, in which the bell rests on the bottom piece, so that the housing (3'; 103'; 203') can receive another non-solid food product.

[0023] Other features of the invention of the packaging device according to the invention:

[0024] The bottom part and the cover are at least partially made of a mouldable plastic material, in particular an injection mouldable plastic material, in particular expanded polystyrene, while the bottom plate and the bell are made of stainless steel.

[0025] In a first configuration, the bell and the cover mutually delimit a thermally insulating so-called first upper intermediate space (8; 108; 208), while the base plate and the bottom piece mutually delimit a thermally insulating so-called first lower intermediate space (9; 10; 209).

[0026] In the second configuration, the base plate and the cover mutually delimit a thermally insulating so-called second upper intermediate space (8'; 108'), while the bell and the bottom piece mutually delimit a thermally insulating so-called second lower intermediate space (9'; 109').

[0027] - In the second configuration, the cover (206) rests directly on the bottom part (201), without defining an intermediate space.

[0028] The bottom plate and the bell define mutually nested areas (E, E'; E1, E'1) in the first configuration and in the second configuration.

[0029] The bottom plate and the bell define a mutually nested zone (E'2) only in the second configuration, the bottom plate having an edge (242) protruding opposite the bell in the first configuration.

[0030] - In a first configuration, the edge rests on the bottom part so as to define a lower intermediate space (E209).

[0031] - In the first configuration, the upper surface (S240) of the bottom plate is located at substantially the same height as the upper surface (S212) of the bottom member.

[0032] The bottom piece defines, in a first configuration, a first blocking area (B; B1 ; B2 ) with the bottom plate and, in a second configuration, a second blocking area (B′; B′1 ; B′2 ) with the bell.

[0033] The bottom part comprises supporting means suitable for supporting the bottom plate in the first configuration and the bell in the second configuration, these supporting means notably comprising a continuous peripheral flange (14) or a plurality of point supports (114).

[0034] The bottom piece has a base extending upwardly from a seat (212), the inner surface (213) of which is smooth so as to define, together with the bottom plate and the bell, a blocking area.

[0035] The cover is movable relative to the bottom piece between a closed position and an open position, said movement being achieved by vertical sliding on the basis of means resting on the bottom piece, said means advantageously comprising quick-locking means between the cover and the bottom piece.

[0036] - The inner diameter of the cover (2) is close to the outer diameter of the bottom part (1), and the inner wall of the cover can cover the outer wall of the bottom part.

[0037] - The outer diameters of the bottom part (101) and the cover (102) are substantially the same, and the mutual fixation between the base and the cover is ensured by the cooperation between the cylinder (122) of the cover and the seat (112) of the bottom part (101), in particular, by the chimeric connection cooperation between the skirt (116) formed on the cylinder and the thin wall (124) arranged on the seat.

[0038] The mutual fixation between the bottom part and the cover is ensured by an electrical snap-fit ​​fastening, in particular by a rib of the cover which penetrates detachably into a groove in the bottom part.

[0039] - In a first configuration, the bottom plate is perforated to allow drainage of condensate from solid food products such as pizza.

[0040] These additional features may achieve the above-mentioned primary objectives individually or in any technically compatible combination.

[0041] The invention also relates to the use of an apparatus as described above for consecutively packaging and transporting different types of food products, such as solid food products, such as comprising food dough, such as pizza (P), and then such as non-solid food products (S).

[0042] Other features according to the above uses:

[0043] - The bottom piece, the lid, the bottom plate and the bell are assembled together at the same time as they are filled with the food product to be transported, so that this assembly takes place without adding any additional time.

[0044] - Before filling with the food product, the base plate and the bell are heated to a temperature close to that of the food product.

[0045] - Placing a base plate (4) on the bottom part (1), placing the solid food product (P) on the base plate, placing a bell (6) on the base plate to form a receiving housing (3), which is then covered with a lid (2).

[0046] - Placing the bell (6) on the base, pouring the non-solid food product (S) into the bell, placing the base plate (4) on the bell to form a receiving housing (3'), which is then covered with the lid (2).

[0047] These additional features may achieve the above-mentioned second primary objective individually or in any technically compatible combination. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Figures 1 to 6A packaging device according to a first embodiment of the invention is shown, which is indicated as a whole by the reference numeral I. The device is more particularly suitable for receiving different types of food products. As mentioned above, the present invention more particularly relates to such a device suitable for packaging solid and non-solid products. In the various drawings, in particular Figures 2 to 6 In the drawings, for the sake of clarity, the actual proportions of the various components of the device 1 are not necessarily shown to scale. In addition, in order to better emphasize the different features of the present invention, these proportions may be changed in different drawings.

[0065] The device 1 first comprises a bottom part 1, and a cover 2 which can cooperate with the bottom part. In the following text, the terms "upper", "lower", "center", "peripheral", "horizontal" and "vertical" refer to the normal operating position of the device. Essentially, this normal position corresponds to the bottom part resting on a horizontal surface (such as a table). It is also noted that in Figure 2 In the figure, XX and YY represent the longitudinal direction and the transverse direction of the device I, respectively.

[0066] In more detail, the bottom part 1 comprises a base 10 from which a cylindrical neck 11 extends upwards. The neck 11 extends a peripheral seat 12 surrounded by a side wall 13. Finally, a flange 14 extends radially inwards from the neck 11. This flange defines, together with the seat 12, a shoulder 15, the function of which will be described below. In order to ensure optimal stability, in particular by avoiding any slipping, the lower surface of the base is advantageously equipped with stabilizing pins, not shown.

[0067] The cover 2 first comprises a circular top portion 20, the diameter of which is slightly larger than the diameter of the bottom portion. A cylindrical body 22 extends downwardly from the top portion. The typical thicknesses of the bottom portion and the cover are Figure 2 The thickness E1 and E2 are between 2 and 6 millimeters (mm), in particular close to 4 mm. The thickness can be varied in particular depending on the overall dimensions of the packaging device. The bottom part 1 and the cover 2 define an inner space V, in particular Figure 4 and Figure 6 As can be seen in FIG. 1 , the internal space V is used to accommodate a receiving housing, as described below.

[0068] Advantageously, the bottom part and the cover are provided with additional quick-locking means. Figure 1 In the example shown, the side wall 13 has at least one pin 16, in particular a hemispherical pin. Preferably, a plurality of pins are provided, for example four in number, evenly distributed in a regular manner. Each pin cooperates with a notch 24 formed at the lower end of the cylinder 22. Considering that the notches are advantageously L-shaped profiles, different notches allow the corresponding pins to be locked, which ensures a reliable locking between the bottom part and the cover.

[0069] According to an advantageous feature of the invention, both the bottom part 1 and the cover 2 are made of a moldable plastic material. Thus, the bottom part 1 and the cover 2 are suitable for industrial molding operations, in particular injection molding, and can be produced in large quantities. This moldable material is advantageously a plastic material having thermal insulation properties, such as expanded polystyrene as a non-limiting example. This material can also be of the "bioplastic" type, i.e. made, for example, from sugar cane or the like, or even of wood.

[0070] The bottom plate 4, which has a disc shape, defines a horizontal plate 40 for receiving solid food products, as described below. From this plate 40 extends a vertical projection 42, forming a rim which itself terminates in a peripheral crown 44. The bell 6 first comprises a top 60 from which extends a cylindrical rim 62. Unlike the bottom member and the lid, the bottom plate and the bell are not made of plastic material, but are preferably made of stainless steel. Typical thicknesses of the bottom plate and the bell are 1000 mm and 1000 mm, respectively. Figure 2 In the E4 and E6, between 1mm and 3mm, especially close to 2mm. As mentioned above, this thickness may vary according to the overall size of the packaging device.

[0071] The dimensions of the base plate 4 and the bell 6 are such that these two parts can fit into each other, but also allow each of these parts to be locked relative to the bottom part 1. Figure 2 , under these conditions, the outer diameter D62 of the edge 62 is close to the outer diameter D40 of the plate 40. Moreover, taking into account the thickness of the edge 42, the diameter D42 is similar to the inner diameter D12 of the seat 12.

[0072] The overall dimensions of the above device depend first of all on the size of the food product it must receive. In the case where this device is used to receive pizzas, the size of which may vary in particular from country to country, the outer diameter of the bottom piece is chosen to be between 20 cm and 70 cm as a guide. Based on this diameter value, we will choose the height of the bell-shaped piece to be H6, as Figure 2 As shown, it is well suited to the typical volumes of non-solid food products served during each sales period.

[0073] Now refer to Figures 3 to 6 The use of the above-mentioned adjusting device I is specifically explained.

[0074] First, it is assumed that it is desired to package a solid food product, in particular a product based on food dough, such as pizza P. To this end, Figure 3 As shown, the bottom plate 4 is connected to the bottom part 1 by cooperating the edge 42 with the shoulder 15. The bottom plate is then blocked relative to the bottom part at the level of the zone B, while the peripheral crown 44 rests on the seat 12.

[0075] If the Figure 3As shown, the operator can then place the pizza P directly on the plate 40, advantageously immediately after the pizza P is taken out of the oven. Figure 4 As shown, the operator then covers the plate 40 and the pizza with the bell 6 in the direction of the arrow F6. At the end of this movement, the periphery 64 of the edge 62 rests on the inner surface of the opposite edge 42 at the level of the zone E.

[0076] According to an advantageous feature of the invention, both the base plate 4 and the bell 6 are heated to a temperature close to that of the pizza before the pizza is placed on the plate. Under these conditions, there is no significant heat exchange between the pizza and the base plate and the bell. Therefore, the temperature of the pizza hardly decreases before eating. This is advantageous from an economic point of view, since the consumer rarely or does not need to reheat the pizza. In addition, avoiding such reheating allows better preservation of the taste of the pizza.

[0077] exist Figure 4 In this first configuration, the reception is ensured by the bottom plate, which together with the bell forms a first receiving housing 3, more particularly for solid food products. It should be noted that this substantially closed receiving housing is defined directly by the bottom plate 4 and the cover 6 in stainless steel, which is particularly advantageous in terms of thermal insulation. The term "directly" means that no other mechanical parts, especially plastic, are interposed between the pizza and the aforementioned stainless steel element.

[0078] Still refer to Figure 4 , the operator finally places the cover 2 around the bottom piece which supports the base plate, the pizza and the bell. This step is done by an axial movement from top to bottom, as indicated by the arrow F2. During this axial movement, the operator first makes each pin 16 enter the entrance of the corresponding notch 24. Then, the operator moves according to Figure 1 The cover is rotated by the arrow F2 in order to place the pin in the recess. The receiving housing is then placed in the internal volume V defined by the bottom part and the cover. Thus, the packaging device I according to the invention is ready for transport by the final consumer himself or by a professional courier.

[0079] In the second step, we assume that we want to package a non-solid food, such as a portion of soup labeled S. To do this, refer to Figure 5 , we connect the bell 6 to the bottom part 1 instead of the bottom plate 4 described above. Under these conditions, the top 60 of the bell rests on the upper surface of the flange 14, closed laterally by the wall of the shoulder 15 at the level of the area B'.

[0080] like Figure 5As shown, the operator can then pour the soup S directly into the bell-shaped member 6 until it reaches a certain height of the edge 62 of the bell-shaped member 6. Similar to the way in which the pizza is placed on the bottom plate described above, it is advantageous to preheat the bottom plate and the bell-shaped member to a temperature close to that of the soup S. Figure 6 As shown, the operator then brings the base plate 4 to the level of the zone E′ by fitting the edge 42 around the periphery 64 .

[0081] exist Figure 6 In this second configuration, the bottom plate and the bell form a second receiving housing 3' which is turned over relative to the upper first housing 3. Figure 4 In the manner described, the operator covers the bottom part 1 with the cover 2 and then locks the two parts together. The packaging device according to the present invention, now containing the non-solid food product, is ready for transportation.

[0082] As in Figure 4 and Figure 6 As shown more specifically in FIG. 1 , in one or another configuration of the receiving housing 3 or 3 ′, respectively, the adjustment device defines different intermediate spaces. Figure 4 In the first configuration, the cover 2 and the bell 6 define an upper intermediate space 8, while the bottom part 1 and the bottom plate 4 define a lower intermediate space 9. Figure 6 In the second configuration, the cover 2 and the base plate 4 delimit a further upper intermediate space 8 ′, while the bell 6 together with the bottom piece 1 delimit a further lower intermediate space 9 ′.

[0083] The upper intermediate spaces 8 and 8' have similar thicknesses. Figure 4 and Figure 6 Typically, these thicknesses E8 and E8' have values ​​between 6 mm and 8 mm. Similarly, the lower intermediate spaces 9 and 9' have similar thicknesses, at the same Figure 4 and Figure 6 In the embodiment of the present invention, the thickness of the packaging device is marked as E9 and E9 '. Typically, the values ​​of these thicknesses E9 and E9 'are also between 6 mm and 8 mm. It should be noted that these different thicknesses are generally constant, regardless of the overall size of the packaging device. In addition, the thickness of each upper space 8 or 8 'is generally similar to, in particular identical to, the thickness of each lower space 9 or 9 '.

[0084] Figures 7 to 12 A second embodiment of a food product packaging device according to the present invention is shown. Figures 7 to 12 In the above Figures 1 to 6 Similar mechanical elements in the drawings are given the same reference numerals increased by 100.

[0085] The packaging device according to this second embodiment is indicated as a whole by the reference numeral II and differs from I primarily in the structure of a base plate 104. In fact, the latter has no crown, such as crown 44, so that this base plate 104 is formed by a plate 140 extended only by a projecting edge 142.

[0086] The removal of the crown makes it possible to reduce the outer diameter of the cap 102 to be substantially the same as that of the bottom part 101. Fig.10 As shown, the mutual fixation between the bottom part and the cover is ensured by a skirt 124 formed on the cylinder 122 of the cover, which cooperates by cooperating with a thin wall 116 provided on the seat 112 of the bottom part. As a variant not shown, other fixing systems can be provided, replacing or supplementing the above-described systems. These include the use of clamps, external closure systems, etc.

[0087] The bottom part 101 also differs from the bottom part 1 in that the bottom part 101 does not have a continuous support flange 14. Instead, the seat 112 of the bottom part 101 comprises a plurality of support surfaces 114, each extending in a sector at a small angle. Furthermore, the base 110 of the bottom part 101 comprises a central boss 118 and a plurality of protrusions 119 arranged in the vicinity of the boss. Similarly, the top 120 of the cover 102 is also equipped with a central boss 128 and peripheral protrusions 129. Finally, the outer surfaces of the base 110 and the top 120 are provided with ribs 117 and 127, respectively, to ensure a reinforcement function.

[0088] Reference Figures 7 to 12 The use of the described regulating device II is generally similar to the use of the device I explained above. Fig.11 If it is desired to package a food dough product, such as a pizza P, the bottom plate 104 is placed on the bottom part 101. The plate 104 of the bottom plate rests on the one hand on the support 114 and on the other hand on the bosses 118 and the protrusions 119. In this first configuration, the blocking area of ​​the bottom plate relative to the bottom part is marked B1.

[0089] We then place the pizza P back on the plate 140 and cover the bottom plate with the cover. As in the first embodiment, there is a mutual nesting area between the bottom plate 104 and the bell 106. In addition, the bosses 128 and the protrusions 129 of the cover 102 abut against the top 160 of the bell. As described with reference to the first embodiment, it is advantageous to heat the bottom plate and the bell to a temperature close to that of the pizza before inserting the pizza into the receiving shell 103. The operator finally places the cover 102 against the bottom piece 101 so that the skirt 116 and the cylinder 122 are matched. Fig.11 In the structure we find intermediate spaces 108 and 109, similar to 8 and 9 in the first embodiment.

[0090] If it is desired to package a non-solid food product, such as soup S, the bell-shaped member 106 is placed on the bottom member 101, such as Fig.12 As shown. The top 160 of the bell 106 then rests on the support surface 114, and on the bosses 118 and the protrusions 119. As in the first embodiment, the soup S is then poured into the inner volume of the bell, and the bottom plate 104 is then replaced. We mark B'1 as the blocking area between the bell and the bottom, and as mentioned above, there is a nesting area between the bell and the bottom. Fig.11 As shown, the cover 102 is then connected to the bottom member. Fig.12 In the second configuration shown, we find intermediate spaces 108' and 109', similar to 8' and 9' in the first embodiment.

[0091] Figures 13 to 15 A third embodiment of a food packaging device according to the present invention is shown. Figures 13 to 15 In, similar to Figures 7 to 12 Those mechanical elements of the second embodiment described in , are given the same reference numerals increased by 100.

[0092] The packaging device according to this third embodiment, which is indicated as a whole by the reference numeral III, firstly has a bottom plate 204 similar to the bottom plate 104 of device II. Thus, this bottom plate 204 comprises a plate 240 extending beyond an edge 242, without a peripheral flange. Furthermore, the structure of the bell 260 is similar to that of the bell 160 belonging to device II.

[0093] On the other hand, the bottom part 201 and the cover 202 of the device III are different from the mechanical elements 101 and 102 of the device II, in particular, the bottom part 201 and the cover 202 have a simplified structure. Therefore, the bottom part 201 includes a base 210, through which a seat 212 extends upwards, and a peripheral groove 216 is formed in the upper part of the seat 212. The cover 202 includes a top 220, through which a cylinder 222 extends downwards, and a peripheral rib 224 is provided at the lower part of the cylinder 222. The rib can be matched with the groove 216 by an elastic snap. This provides a reliable connection between the bottom part and the cover, which can be easily removed.

[0094] The implementation of the device III described below differs significantly from the implementation of the devices I and II above. In particular, Fig.13 and Fig.14 As shown, in a first functional configuration, the base plate 204 rests directly on the base 210 of the bottom part 201. Figures 1 to 12Unlike the embodiment of the present invention, the edge 242 does not protrude upwards, but instead protrudes downwards. Therefore, the presence of this edge 242 helps to form the intermediate space 209. This feature simplifies the structure of the bottom part, that is, the inner surface 213 of the seat 212 is advantageously smooth. We mark B2 as the blocking area between the smooth surface 213 and the edge 242, similar to the previous areas B and B1.

[0095] Furthermore, the plate 240 of the base is advantageously perforated with small holes, not shown. Fig.13 As shown, these holes allow condensate from the pizza to drain, which is indicated by arrow C. Furthermore, by advantageously providing a bottom piece made of a high porosity material, such condensate can drain from the device through the bottom piece according to arrow C'. It should be noted that the features described in this paragraph can be combined with other embodiments.

[0096] Fig.14 A particularly advantageous feature of the invention is shown. As mentioned above, the edge 242 does not protrude above the plate 240. Moreover, the surface S240 of the plate is substantially at the same level as the upper surface S212 of the seat 212. With this in mind, it was chosen to provide female fixing elements, such as the groove 216, in the seat 212 instead of in the lid. When tasting the pizza, after removing the lid 202 and the bell 206, the pizza can slide along the upper surface of the base and the seat according to arrow G. This is particularly convenient for the consumer.

[0097] like Fig.15 As shown, in the second functional configuration, the realization of device III also differs from that of device I and device II. In fact, the top 260 of the bell 206 rests directly on the base 210, so there is no intermediate space similar to 9 and 109 in the previous figures. However, as a variant shown in dashed lines, a boss 214 can be formed on this base. This makes it possible to raise the cover 206 and in this way create an intermediate space 209', also shown in dashed lines.

[0098] Furthermore, in this second functional configuration, the base plate 204 and the cover 206 are nested with each other, as in the other embodiments. Fig.15 Arrangement, wherein the cover is placed on the bottom part, the height of the free space 208 'formed between the cover and the base is higher than the height of the upper spaces 8 'and 108 '. If the cover is raised by a boss, the size of this space is similar to that in the previous embodiment.

[0099] According to an advantageous feature not shown in the drawings, which can be combined with any of the embodiments described above, the device can include sealing means. In particular, any suitable type of seal can be provided, for example a seal made of rubber, which is inserted between the wall opposite the bottom plate and the bell. Such a seal ensures tightness relative to the receiving housing, which is particularly advantageous in the case of liquids or semi-liquids.

[0100] The above description highlights various advantages of the present invention.

[0101] Firstly, the presence of a receiving casing with two different configurations ensures an optimal packaging of any type of food product. Thus, in a first configuration, the substantially flat surface of the plate allows for easy placement of a pizza or any other similar product. Furthermore, in a second configuration, the hollow shape of the bell ensures convenient reception of any type of non-solid food product. Furthermore, there is no mutual contact of the food product between the receiving casing and the bottom piece and its cover.

[0102] The present invention provides a significant improvement over the prior art in terms of economy. In essence, the device of the present invention consists essentially of four main parts, which can be easily manufactured separately. Depending on the final size of the packaging device, only the diameter or height of each part thereof needs to be changed. Therefore, the tools required for this manufacturing are greatly simplified. As an example, it can be considered that the cost of the packaging device according to the present invention is only equivalent to about one-third of that of a traditional double-walled box. In particular, the present invention can avoid any overmolding operation, which is very expensive.

[0103] The present invention also relies on the concept that the operator assembles the packaging device at the same time as the food product to be transported is filled. Therefore, this assembly occurs in no additional time. In other words, the overall length of time required to assemble and fill the packaging device according to the present invention is almost the same as the time required to fill only a traditional carton, or may even be shorter. In addition, a manufacturer of a packaging device in accordance with the present invention can provide two different uses for the same device.

[0104] In particular, thanks to the form fit between the bottom part and the cover, the transport of food products can be carried out in complete safety. Moreover, during transport, the product is kept at an optimal temperature with virtually no heat loss. In this spirit, the device according to the invention has a high thermal insulation capacity. Furthermore, the presence of various intermediate spaces creates air interlayers that contribute to this thermal insulation.

[0105] Once the packaging device has reached the point of consumption, it is convenient to remove the cover opposite the bottom piece. To this end, we will note the possibility of sliding in the vertical direction between this cover and this bottom piece. Unlike some prior art boxes that require an articulation between the cover and the bottom piece, this sliding movement allows the device to maintain a circular structure, ensuring a saving of material.

[0106] It should also be noted that a combination of plastic material (eg bioplastic) and stainless steel is particularly advantageous.

[0107] On the one hand, such plastic materials can be easily used for labeling operations, for example, being able to identify the name of the manufacturer. In addition, given their plastic nature, such materials can be manufactured industrially on a large scale. Finally, in the case of bioplastic materials, the latter present significant ecological characteristics.

[0108] On the other hand, stainless steel has high heat-insulating properties. In particular, electromagnetic radiation may be induced, reflecting heat onto the food. Moreover, in the first configuration, the consumer may not only cut solid products on the stainless steel base plate, but also eat directly on this base plate, so that the base plate forms a flat plate. Moreover, in the second configuration, the consumer may taste non-solid products directly in the bell-shaped piece, when the bell-shaped piece forms a hollow plate.

[0109] The use of these two different materials also allows separate treatment between the cover and bottom part on the one hand and the receiving housing on the other. Due to its stainless steel structure, this housing can be easily cleaned at high temperatures without affecting the cleaning of the bottom part and the cover. On the other hand, since plastic materials are more fragile, they require more gentle cleaning, especially for bioplastic materials that cannot withstand temperatures exceeding 30°C, and the bottom part and cover are only wiped aseptically. Finally, the stainless steel parts on the one hand and the plastic parts on the other hand can be destroyed and recycled separately after long-term use.
