Description

PACKAGING FOR PRESENTATION AND STORAGE OF CULINARY PREPARATION PORTIONS Field of the invention

The field of the invention is that of the storage, conservation and presentation of elaborate culinary preparations, in the form of single pieces. More particularly, the invention relates to packaging suitable for such pieces of culinary preparations, for example petit fours, appetizers or portions of a prepared dish, etc.

Prior art

Such culinary preparations are often produced by caterers, and supplied by them on trays, for immediate consumption. In this case, no solution is provided for long-term preservation, transport and storage, or quality presentation, particularly for elaborate products.

For example, it is not possible to provide such preparations in transport, for example on planes, or on demand, for example in a restaurant, without having to call on a cook to prepare them and shape them. and present them.

We also know, in the field of packaging of food products, numerous solutions, allowing for example marketing in mass distribution.

In particular, we know of packaging in the form of a box comprising a container covered with a removable or hinged lid in which it is possible to store food products in a more or less orderly manner.

Generally, these boxes are made of plastic such as polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), expanded polystyrene (EPS), high density polyethylene (HDPE) or low density polyethylene (LDPE). ) or polyvinyl chloride (PVC).

In order to improve the storage of food products, particularly when it comes to fragile culinary preparations, some boxes use a plastic support base. These support bases may have cells capable of receiving and ordering the products. These support bases are for example used for packaging relatively fragile petit fours, such as macaroons for example.

A disadvantage of this solution lies in the fact that the box and/or the support base cannot be used for reheating to temperatures above 120°C. It is therefore necessary to use plastics that are more heat resistant, and therefore more expensive.

Another disadvantage of this solution lies in the fact that the manufacture of the container, the lid and the base sometimes requires the use of different materials for each of these elements, knowing that these different materials are not always compatible with sorting. selective or have different recycling methods. It is therefore difficult for the user to recycle these elements correctly.

This solution is therefore not satisfactory, in particular because these packaging is disposable, that is to say for single use. Moreover, the majority of packaging currently used is not biodegradable and therefore has a significant ecological impact when it is not recycled correctly.

Yet another disadvantage is that the presentation of the products is done, at best, via a base acting as a tray, of poor quality and impractical to use. The user can, of course, move the portions one by one onto a tray or a plate, but such manipulation is time-consuming and unhygienic, due to the possible contact between the hand and the product.

We also know the use of parchment paper for packaging or only to serve as an individual presentation support for each portion of food product. The use of such paper makes it possible in particular to prevent the culinary product from sticking to the box in which the food products are placed.

A disadvantage of this solution lies in the fact that the presentation of the food products in the box is not aesthetic, even when the paper is shaped (for example when it is corrugated or pleated on its periphery). The same applies to the general presentation of the packaging, for example when it is placed on the shelf of a store. This also constitutes a recurring drawback of packaging known for storing and presenting culinary products.

Another disadvantage lies in the fact that the transport of food product packaging is not always simple, in particular due to the particular shape of some of these packaging and portions, and the sometimes elaborate nature, for example in several layers.

There is therefore a need to provide a new solution for packaging culinary portions which is ecological, easy to use, aesthetic, ecological, which allows good conservation and easy transport, in particular for elaborate, high quality culinary products. and consequently requiring an optimal and original presentation, while not requiring, at the time of presentation and preparation just before this presentation, the intervention of a specialist, in particular a caterer or a cook. The invention must therefore also allow easy reheating of culinary preparations when necessary.

The technique of the invention makes it possible to resolve at least some of the drawbacks raised by the prior art. More specifically, the invention relates to packaging for the storage and presentation of culinary preparations in the form of a series of unit portions.

• une base principale réalisée en un matériau biodégradable à base de pulpe de canne à sucre, présentant un premier fond et un premier rebord s'étendant à partir de la périphérie dudit premier fond ;
• une pluralité de bases secondaires destinées à être placées dans ladite base principale et aptes à recevoir chacune une desdites portions unitaires, réalisée en un matériau biodégradable à base de pulpe de canne à sucre et présentant chacune un second fond et un second rebord s'étendant à partir de la périphérie dudit second fond, au moins ledit second fond étant recouvert d’un revêtement biodégradable étanche ;

According to the invention, the packaging comprises:

• a main base made of a biodegradable material based on sugar cane pulp, having a first bottom and a first rim extending from the periphery of said first bottom;
• a plurality of secondary bases intended to be placed in said main base and capable of each receiving one of said unit portions, made of a biodegradable material based on sugar cane pulp and each having a second bottom and a second rim extending to from the periphery of said second bottom, at least said second bottom being covered with a waterproof biodegradable coating;

- a cover for the protection and storage of portions of culinary preparation, able to fit onto said main base.

The dimensions of said main base and said cover are defined so that they can receive said plurality of secondary bases along a single line.

Thus, we have original and innovative packaging, particularly suitable for the conservation and presentation of elaborate culinary preparations and entirely biodegradable.

According to one aspect of the invention, said cover has the shape of a truncated pyramid.

This makes it easier to stack and store a lid assembly, and gives a premium appearance to the package.

According to another aspect of the invention, the packaging comprises a transparent protection made of a biodegradable material which fits onto said secondary bases.

Such transparent protection, intended to be affixed to a secondary base, makes it possible to avoid the transfer of flavors between two portions of adjacent culinary preparations. The transparent protection also improves the preservation of the culinary preparation. It also plays a role in protecting the culinary preparation against the external environment (e.g. insects; contact by the consumer, etc.) particularly when the packaging is used/presented on a buffet. The transparent protection also makes it possible to aesthetically present the portion of culinary preparation on its secondary base. The transparent protection can also help maintain the temperature of the culinary preparation after reheating.

According to a particular aspect of the invention, said waterproof biodegradable coating may be recycled polyethylene terephthalate (RPET).

The use of recycled polyethylene terephthalate, which is a laminated material, makes it possible to avoid the transfer of material between the secondary base and the culinary preparation portion. Such a material is compatible with reheating in the oven and storage by freezing. This material, biodegradable and compostable, also prevents the portion of culinary preparation from sticking to the secondary base.

According to another particular aspect of the invention, the first bottom of said main base and the second bottoms of said secondary bases can be substantially rectangular or square.

Such a shape allows optimal retention of the culinary preparation in the packaging. It also facilitates the assembly of covers and transparent protectors on the main bases and secondary bases, respectively. The storage of a plurality of packaging by superposition/stacking is also made easier. Finally, this shape is particularly suitable for delivery or for use in planes/boats, in particular.

According to yet another particular aspect of the invention, the packaging may carry a unique identification code of said culinary preparation(s) stored and presented in said packaging.

The implementation of such a code allows in particular optimal traceability of culinary preparations.

In particular, said identification code and/or a second code can be configured in the form of an image readable and interpretable by suitable electronic means, to enable information relating to said portion(s) of stored culinary preparation to be obtained. and presented in said packaging.

Such a code, for example of the QR code type, makes it possible to provide precise information on the portions of culinary preparation stored and presented in the packaging, such as the product identifier, its recipe, nutritional information, allergens, etc., its technical sheet (reheating time, storage, etc.). This code allows optimal consumption of culinary preparations stored in said packaging.

• des informations sur la ou les préparations culinaires contenues dans l'emballage ;
• des informations sur la fabrication et l'origine la ou les préparations culinaires contenues dans l'emballage ;
• des informations sur la conservation et la péremption de la ou les préparations culinaires contenues dans l'emballage ;
• des informations sur l'utilisation, notamment le réchauffage, de la ou les préparations culinaires contenus dans l'emballage.

According to another particular aspect of the invention, said information may belong to the group comprising:

• information on the culinary preparation(s) contained in the packaging;
• information on the manufacture and origin of the culinary preparation(s) contained in the packaging;
• information on the conservation and expiry of the culinary preparation(s) contained in the packaging;
• information on the use, in particular reheating, of the culinary preparation(s) contained in the packaging.

According to another aspect of the invention, the packaging may comprise a rectangular parallelepiped overpack in which the packaging is intended to be inserted and extracted via one of the short sides of the parallelepiped overpack.

Such overpackaging facilitates storage and transport. It also makes it easier to present and store the packaging according to the invention on product sales shelves. Such overpackaging is particularly suitable for facilitating the use of the packaging in planes/boats/trains or for deliveries, in particular.

Said outer packaging may in particular be sealed using a single-use security element, demonstrating that the packaging has not been opened.

This security element ensures optimal storage, limiting the risk of unwanted opening of the outer packaging. The security element, for example in the form of a ring, also makes it possible to guarantee the traceability of the culinary preparation(s) contained in the packaging inserted in the outer packaging.

According to another particular aspect of the invention, said cover may comprise at least one stop configured to allow controlled stacking of several covers for the storage of the latter.

The implementation of this stop facilitates storage, transport of the empty packaging (i.e. without portion of culinary preparation) and the separation of stacked lids.

According to a particular aspect of the invention, the packaging can be configured to withstand high temperatures, i.e. at least 240°C, and very low temperatures, i.e. at least -180°C.

The packaging of the invention is thus adapted to allow optimal conservation in a freezer or refrigerator, as well as cryogenic treatment. It is also suitable for allowing reheating or cooking of the culinary preparation(s) in an oven, for example.

Detailed description of the invention

The general principle of the invention is based on the implementation, for presentation and storage packaging of portions of culinary preparations, of a plurality of elements made of biodegradable materials.

Figures 1 and 2 partially illustrate an example of packaging 1 according to the invention.

Such packaging 1 comprises in particular an elongated main base, or tray 10 and a cover 11 intended to cover the central base 10. The central base 10 and the cover 11 are made of sugar cane pulp, which is a biodegradable material and recyclable. Such packaging therefore has a very low ecological impact.

In addition, such a material is able to withstand high temperatures, in particular above 240°C, in order to allow culinary preparations to be reheated before consumption, in an oven for example. Such a material therefore avoids, when heating to such temperatures, a transfer of flavors or deterioration of the latter.

In addition, such a material is also able to withstand very low temperatures, in particular below -180°C. Thus, the portions of culinary preparation stored within the packaging according to the invention can be easily preserved. They can also be frozen directly in their packaging, and undergo cryogenic treatment.

The main base 10 has a substantially rectangular shape.

The main base 10 comprises a bottom 101 as well as a rim 102 extending from the bottom wall 101, and over the entire periphery of the bottom wall 101. This rim can be perpendicular to the bottom or, preferably , form an angle significantly greater than 90° with it.

More precisely, the rim forms with the bottom, according to the illustrated embodiment, an angle α of approximately 92°, as illustrated in the which is a longitudinal sectional view of the cover 11 and the main base 10. Such an angle allows a stacking of several main bases 10 when the latter are not used for the presentation and storage of portions of culinary preparation. Thus, controlled stacking of the main bases 10 is permitted, for storage before and after use. The separation of the main bases 10 is also facilitated by this slightly obtuse angle.

Such a rim 102 also makes it possible to maintain the position of the cover 11 on the main base 10. Indeed, the dimensions of the cover 11 and the main base 10 are adapted so that the cover 11 is affixed to the main base 10 without the latter cannot move, in rotation and in translation in particular, relative to the main base 10.

The cover 11 is substantially in the shape of a truncated pyramid, having a bottom wall 111 extended, on its periphery, by a side wall 112 extending in an inclined manner relative to the bottom wall 111. More precisely, the side wall 112 is inclined at an angle β of approximately 95°, as illustrated in the which is a longitudinal sectional view of the cover 11 and the main base 10.

The end of the side wall 112 of the cover 11 opposite the bottom wall 111 forms an edge 113 having a general shape corresponding to the bottom wall 101 of the main base 10. As indicated above, the side wall 112 has , at the level of its edge 113, dimensions adapted so that the cover 11 cooperates with the central base 10.

As illustrated on the , the corners of the side wall 112 have stops 114 which allow easy and optimal stacking of the covers 11 when they are not used to cover a main base 10 and the portions of culinary preparation which it contains. Thus, the stops 114 allow controlled stacking of the covers 11 to promote their storage. The stops 114 also allow the lids not to be stacked too deeply inside each other in order to facilitate their separation.

In this example, each angle, or corner, of the side wall 112 has such a stop 114. It is however possible to implement only two stops 114, for example in opposite corners. It is easy to understand that it is also possible to implement stops 114 at other locations along the side wall 112, on the face facing the inside of the cover 11.

As illustrated on the , packaging 1 carries an identification code 115, here affixed on the cover 11. This identification code 115 is unique and allows optimal/complete traceability of the culinary preparations presented and stored in the packaging. Identification code 115 could be positioned differently on packaging 1, provided that it is easily accessible.

For example, the unique identification code 115 is in the form of a barcode or a QR code (for “Quick Response Code” in English). This unique identification code 115 makes it possible to obtain, in addition to traceability information, various information on the culinary preparation(s) kept in packaging 1.

For example, such an identification code 115 can make it possible to retrieve different information, such as the identifier/commercial name of the culinary preparation(s), the recipe, nutritional information, allergens or information relating to preparation/consumption. culinary preparations, such as storage temperature, optimal reheating conditions or use-by date.

There illustrates another example of a packaging 1 according to the invention. The main base 10 as well as the cover 11 are substantially identical to the main base and the cover described above in relation to Figures 1 and 2. The main base 10 and the cover 11 of the differ from the main base and the cover of Figures 1 and 2 only in that their dimensions are different.

This illustrates an essential aspect of the invention. Indeed, according to the invention, the packaging 1 receives a plurality of secondary bases 12 intended to be arranged on/in the main base 10, as illustrated in the . Each of these secondary bases 12 is intended to receive a unit portion of culinary preparation (not illustrated).

The dimensions of the secondary bases and the main base are adapted so that the unit portions, and therefore the secondary bases, are presented in an aligned manner, so as to be easily presentable and consumable. In some cases, all servings are the same. In other cases, they may be different, and correspond for example to a succession of dishes, possibly from starter to dessert. This approach is particularly interesting for consumption by a single individual, for example on a plane or in their hotel room.

The secondary bases 12 are made from sugar cane pulp, which is a biodegradable and recyclable material. Such packaging therefore has a very low ecological impact. Furthermore, such a material is able to withstand high temperatures and low temperatures, as described previously. Such a material is therefore compatible with the intended use for such packaging.

According to the invention, the upper face 123 of the bottom wall 121 of each secondary base 12 is covered with a coating of waterproof biodegradable material. More precisely, the upper face 123 is the face of the bottom wall intended to receive, that is to say to be in contact, with the culinary preparation.

The implementation of this additional waterproof coating is essential for the presentation and conservation of the culinary preparation, and in particular ensures optimal presentation (absence of stains or leaks of food products), and facilitates the separation of the portion , at the time of consumption.

The material covering the upper face 123 is preferably recycled polyethylene terephthalate (RPET). Such material is compatible for use with food products and is resistant to high temperatures (above 240°C) and low temperatures (below -180°C).

Such a material makes it possible to protect the secondary base 12 from humidity and therefore avoids unwanted degradation of the secondary base 12, in particular when reheating the culinary preparation.

A secondary base 12 is illustrated in more detail in Figures 4 and 5 . Each secondary base 12 can be optionally covered by a protective cap or shell 13, preferably transparent, which makes it possible to individualize and protect the portion of culinary preparation present on each secondary base 12 before consumption.

The secondary base 12 has, in the example illustrated in these figures, a substantially square shape. We obviously understand that the secondary base 12 could also have a substantially rectangular shape, in particular. The shape and dimensions of the secondary base 12 are defined to correspond with the shape and the dimensions of the main base 10. In fact, the secondary bases 12 are arranged in the main base 10 such that they are placed one against the other. against the others in order to prevent movement of the latter in the main base 10, in particular during transport. In other words, the secondary bases 12 are wedged against each other in the main base 10.

The secondary base 12 comprises a bottom 121 as well as a rim 122 extending substantially perpendicular to the bottom wall 121, and over the entire periphery of the bottom wall 121.

More precisely, the rim 122 is inclined at an angle σ of approximately 92°, as illustrated in the which is a longitudinal sectional view of the secondary base 12 and the protective cap 13. Such an angle of inclination allows a stacking of several secondary bases 12 when the latter are not used for the presentation and storage of portions of preparation culinary. Thus, a controlled stacking of the secondary bases 12 is obtained. Such a rim 122 also makes it possible to optimally center and maintain each portion of culinary preparation in the secondary base 12.

The protective shell 13, also called protection in the remainder of this description, is preferably made of a transparent material in order to allow the culinary preparation stored and presented in the associated secondary base 12 to be easily identified. In addition, the implementation of transparent protection provides an aesthetic presentation of the culinary preparation.

The transparent protection 13 is substantially in the form of a truncated pyramid extended by a dome. Obviously, other forms can be considered without deviating from the principle of the invention.

Preferably, the transparent protection 13 has a first portion 131 having a shape corresponding to the secondary base 12 so as to cooperate with the latter. More precisely, the first portion 131 of the transparent protection 13 has dimensions slightly greater than the secondary base 12 so as to cover the secondary base 12 and at least partially envelop the rim 122.

The first portion 131 may present, for example at its corners/angles, a locking or blocking means, for example a clip (not illustrated) intended to cooperate with the rim 122 of the secondary base 12 so as to maintain in place position the transparent protection 13 on the secondary base 12.

We illustrate here a transparent protection 13 intended to cover only a single secondary base 12. We could also consider, in a variant not illustrated, implementing a single transparent protection which would cover several secondary bases 12. This single transparent protection could however, be shaped to individually separate each portion of culinary preparation placed on the secondary bases 12.

Figures 6 and 7 illustrate in perspective an overpack 14 in which the package 1 is intended to be inserted, via one of the short sides of the parallelepiped formed. More precisely, the illustrates an empty and open outer packaging 14 while the illustrates a closed overpack 14 in which a package 1 containing portions of culinary preparation have been previously inserted.

Such an overpack 14 has a classic shape, for example parallelepiped with an open end (small side) provided with tabs, or flaps, 141 which allow the overpack 14 to be closed.

The outer packaging 14 is preferably also made of sugar cane pulp, which is a biodegradable and easily recyclable material. Other biodegradable and/or recyclable materials can be used without deviating from the principle of the invention.

Thus, once the portions of culinary preparation are placed on the secondary bases 12, each secondary base 12 is covered by the transparent protection 13 and is placed/arranged on the main base 10 which is then covered by the cover 11.

Optionally, a holding bracelet (not illustrated) can be implemented in order to hold the cover 11 on the main base 10. For example, this holding bracelet could surround the cover 11 and the main base 10 in order to prevent opening unwanted packaging, particularly during transport or reheating. Such a support bracelet is preferably made of a material resistant to high temperatures and very low temperatures, as described above. The support bracelet is also preferably made of an elastic material in order to facilitate its installation and removal on the packaging 1.

Packaging 1 can then be inserted into outer packaging 14 to facilitate its storage and transport. The overpack 14 also makes it easier to present and store, for example on the shelves of a store selling culinary preparations, a hotel, an airplane, etc.

Each outer packaging 14 can be provided with an identification code 145 relating to the packaging 1 and the culinary preparations it contains. This code 145 may be identical to code 115 carried by cover 11 of packaging 1 and described previously. The identification code 145 is for example affixed to one of the tabs 141 of the outer packaging 14, so that it is visible when the outer packaging is stacked during storage, transport or when placed on the shelf. Other positions of the identification code 145 on the outer packaging can be considered without departing from the principle of the invention.

As illustrated on the , a securing ring 142 is used in order to seal the outer packaging 14. In this example, the securing ring is in the form of an adhesive strip placed on the junction of the tabs 141 of the outer packaging 14. Other forms securing rings can be considered without departing from the principle of the invention.

This securing ring 142 makes it possible to avoid unwanted opening of the outer packaging 14 so as, in particular, to guarantee good traceability of the culinary preparations stored in the packaging 1.

There illustrates an example of packaging according to the invention in which the cover 11 is arranged on the main base 10. It is understood that a plurality of secondary bases 12 and transparent protections 13 are arranged inside the cover 11, on the main base 10. Note that the packaging 1 has in this example two securing collars 15 which make it possible to hold the cover 11 in position on the main base 10. Such securing collars make it possible to avoid any unwanted opening of the 'packaging.

For example, these security collars 15 can be decorated and/or carry a logo or any type of advertising. It is the same for the outer packaging 14 described previously.
