Description

Container for transporting, storing and transferring liquid food

The present invention relates to a container for transporting, storing and transferring liquid food for recycling the used food liquid, the food liquid being in particular food oil used by catering establishments or individuals.

In a catering establishment, cooking or food preparations use a significant amount of cooking oil or "frying". The fresh food oil is necessarily transported according to a circuit going from its place of manufacture to its place of use and can thus be stored in these different places according to particular conditions including conditions of safety, hygiene and respect of the environment. When the edible oil is out of date, wasteful, or unusable, it is stored in one or more storage devices while waiting to be recovered for disposal outside the point of use and to a reprocessing unit.

It is known in the prior art means to transport and store used or fresh food oil. The fresh edible oil is transported from its place of manufacture to its place of use and stored in bottles or drums or containers or other of various capacities. The used cooking oil is transported in simple full-opening barrels of various contents into which the used cooking oil is poured via, for example, a hand pump or by hand-handed transfer. Then, periodically, these barrels are replaced by empty drums. The full drums are then sent to a reprocessing plant to reprocess the used food liquid. Then these barrels are cleaned and then transport again to the place of use of the liquid food. The major disadvantage of this technique is that it requires heavy and frequent handling drums, hence the need to release a large storage space in the place of use and use consistent lifting means, means of cleaning the barrels so that they can be used again. In addition, it requires the intermediate displacement of the used oil to the drum storage area, which represents risks during handling. Finally, these means are not adapted to initially receive fresh food oil and in a second time, used food oil.

The present invention aims to overcome one or more disadvantages of the prior art and proposes a container for transporting, storing and transferring liquid food with a simple implementation, cost and space before use low.

The principle of the invention is to provide a container (1) for transporting, storing and transferring liquid food, including edible oil used in cooking devices. It should be noted that the present invention is part of a security context in terms, in particular, of hygiene, supply, ergonomics and handling and environment. The container according to the invention is equally suitable for food service establishments, more particularly food service establishments with low consumption of cooking oil, than for private consumers since it has a simple implementation at low costs.

The present invention will now be described with reference to FIGS. 1 and 2. The container (1) intended for transporting, storing and transferring liquid food comprises a closed structure (10) of characteristic geometrical shape and of predetermined volume (100). at least one bag (1 1) disposed inside said structure (10) and adapted to receive a liquid food by at least one orifice (1 10) of the bag (1 1).

With reference to FIGS. 2 and 3, the structure (10) is formed of a cylinder, for example, with an octagonal base closed at each end (101,

102) of which four parallel edges (105a to 105d) delimit three faces (106a to 106c) among the eight faces of the cylinder. Two adjacent edges (105a, 105b) of the same face (106a) are of different lengths and two edges (105a, 105c), respectively (105b, 105d), separated by two faces (106a, 106b), respectively (106b, 106c) are of the same length to form at the ends (101, 102) of the cylinder adjacent dihedral (D, Â) of opposite orientation and converging towards the concave center (107) and the upper faces.

(101) and lower (102) of each end have concave centers (107h, 107b) distant from a distance less than the smallest length of the edges.

According to another embodiment not shown, the structure (10) is formed of a cylinder, for example, octagonal base closed at each end (101, 102), four parallel edges delimit three faces among the eight faces of the cylinder. Two adjacent edges of the same face are offset and of equal length forming a face having a parallelogram shape and two edges separated by two faces are facing each other to form at the ends (101, 102) of the cylinder dihedral ( D, Â) adjacent in opposite orientation and converging towards the concave center (107) and the upper (101) and lower (102) faces of each end have concave centers (107h, 107b) distant a distance less than the edges .

The structure (10) is made of cellular cardboard or polypropylene material or any other similar material capable of being folded or unfolded and providing a high rigidity of the structure (10).

In this way, the geometry and the material constituting the structure (10) make it possible to give a functional inertia for folding the structure (10) from a plane shape in order to reduce the storage space requirement. before filling the used food liquid with the container (1), unfolding the structure (10) in order to reduce the storage space after the total emptying of the fresh food liquid from the container (1) and a stacking inertia of a plurality of containers (1) to optimize storage and facilitate the transport of containers (1) by a transport optimization system. The container (1) according to the invention is able to cooperate with a ferry with at least one pumping system to perform operations of emptying fresh liquid food container (1) in a cooking device and filling operations of used food liquid from the cooking device to the container (1). In a preferred embodiment shown in FIGS. 1, 2 and 3, the structure (10) has a volume (100) of octagonal shape enabling a simple stack of a plurality of containers (1) without a large positioning force, as illustrated in FIG. 4, a so-called top surface (101) and a so-called bottom surface (102) in diamond-shaped form ensuring a high rigidity of the structure (10) and at least one orifice (103) is provided on the structure (10). It should be noted that in the case where specific uses are envisaged, the geometry of the structure (10) can be optimized according to the uses of the container (1) and can tend towards a cubic volume (100).

In the example shown in Figures 1, 2 and 3, a hole (103) for filling and emptying is located on the top surface (101) of the structure (10).

The structure (10) can be provided with several orifices (103) each having a specific function, in particular the filling and emptying of the pocket (1 1) of the container (1). The structure (10) further comprises handles (104) located on the lateral surface of the structure (10) and symmetrically with respect to the structure (10) to facilitate handling and / or checkpoints for placing the container (1) on a transport system, especially on the ferry with at least one pumping system, and prevent any movement of the container (1) during its transport. The handles (104) and the return elements are made by appropriate cuts in the material constituting the structure (10).

In a preferred embodiment, the structure (10) is made of standard double-fluted cardboard type material. It should be noted that the thickness of the material used in our embodiment example, the double corrugated cardboard, is 6.5 millimeters. But the use of a single or triple corrugated cardboard type material can be envisaged and allow the development of new volumes (100). Indeed, the structure (10) is provided for liquid food contents less than or equal to about 40 liters. Higher volumes (100) of the structure (10) can be envisaged under the condition of using a material constituting the more rigid structure (10), a volume of the pocket (1 1) corresponding to the envisaged volume (100) of the structure (10), and a folding arrangement of the appropriate structure (10). In addition, the advantage of using a cardboard type material is the adaptation in terms of food quality and the possibility of recycling this type of material. Finally, in an exemplary embodiment illustrated in FIG. 3, the structure

(10) volume (100) substantially equivalent to 30 liters has a height (H) substantially equal to 338 millimeters. For a structure (10) volume (100) substantially equivalent to 40 liters, the height (H) of the structure (10) is substantially equal to 437 millimeters. Furthermore, the top surface (101) and bottom surface (102) have a diameter substantially between a first diameter (D1) and a second diameter (D2) regardless of the volume capacity of the structure (10). In the embodiment shown in Figure 3, the first diameter (D1) is substantially equal to 388 millimeters and the second diameter (D2) is substantially equal to 420 millimeters. It is thus possible to modify the volume capacity of the structure (10) by modifying only the height (H) of the structure (10), which facilitates the production and implementation of the structure (10). The geometry of such a structure (10) therefore has the advantage of a minimum space requirement for a maximum capacity and a simple implementation at low cost.

The container (1) comprises at least one pocket (1 1) provided to optimize the interior volume of the structure (10).

In a first embodiment, the container (1) comprises a pocket (1 1), also called container (1) "single-pocket". The bag (1 1) is either adapted to receive a used food liquid opening outwards through an orifice (1 10) associated with an orifice (103) of the structure (10), as illustrated in FIG. adapted to receive a fresh food liquid opening onto the outside through a first orifice associated with an orifice of the structure (10), and then once emptied, to receive a used food liquid opening onto the outside through the same first orifice, or a second orifice associated with another orifice of the structure (10), (configuration not shown). In a second embodiment illustrated in Figure 7, a container (1) comprising two pockets (11), also called container (1) "two-pocket" may be considered. The first bag (11 a) is intended to receive a fresh food liquid opening on the outside by a first orifice (1 10a) associated with an orifice (103a) of the structure (10) and the second pocket (1 1 b) is intended to receive a used food liquid opening on the outside by a second orifice (1 10b) associated with another orifice (103b) of the structure (10). In this example shown in FIG. 7, the first orifice (1 10a) emerges on the outside through the lower part of the lateral surface (100) of the structure (10) to promote the natural emptying of the liquid food towards the device of cooking and the second orifice (110b) of the pocket (1 1 b) opens outwardly through the top surface (101) of the structure (10) to promote the natural filling of the liquid food from the cooking device to the container (1). It should be noted that the first and second orifices (1 10, 1 10a, 1 10b) of the pocket (s) (1 1, 1 1 a, 11 b) can be positioned differently on the structure (10).

The orifices (110, 110a, 1 10b) of the pocket (s) (11, 11a, 11b) are designed to receive connection elements such as quick-release couplings or taps and are also provided to be modifiable in a voluntary and irreversible manner to avoid any error of extraction of the bag (s) in which a used food liquid has already been introduced.

The pocket or pouches (11) are made of flexible material of plastic type, in particular polyethylene (PE). A semi-rigid material may be conceivable.

Each opening (1 10, 1 10a, 1 10b) for filling or emptying the pocket (s) (1 1, 1 1 a, 1 1 b) also comprise a closure system (1 1 1). The closure system (1 1 1) is a plastic type plug and screwable on the orifice (110, 1 10a, 110b) of the pocket (11, 1 1 a, 1 1 b). The pocket or pockets (1 1, 1 1a, 11b) are slid inside the structure (10) during the manufacture of the structure (10) or just before the use of the container (1)

The bag (s) (1 1, 11a, 11b) are capable of receiving a volume of less than or equal to about 40 liters of liquid food without excessive deformation and optimizing the best (100) interior volume of the structure (10) having a volume capacity substantially equal to the volume of the pocket (s) (1 1, 1 1a, 1 1 b). Volumes greater than 40 liters of the pocket (1 1, 1 1a, 1 1 b) can The sealing and fixing between the structure (10) and the pocket (s) is considered

(1 1, 1 1a, 1 1 b) are provided by a locking system for blocking the orifice (1 10, 1 10a, 1 10b) of the pocket (1 1, 11 a, 1 1 b) with the structure (10) and disposed respectively at the orifice (103, 103a, 103b) of the structure (10) This locking system corresponds either to a clever cut made at the orifice (103, 103a, 103b) of the structure (10), or to an addition of a blocking element at the orifice (103, 103a, 103b) of the structure (10)

As previously explained, the geometry and the material constituting the structure (10) make it possible to give a functional inertia for folding-mounting the structure (10) from a plane shape in order to reduce the storage space requirement. before filling the used food liquid with the container (1), removing the structure (10) in order to reduce the storage space after the total emptying of the fresh food liquid from the container (1) The folding of the structure (10) can be done as many times as an operator expresses the need. The assembly by folding or removal of the structure (10) is carried out in a simple manner achievable by everyone and a priori without specific tools and heavy

In the case of a structure (10) of octagonal shape, the planar shape of the structure (10) corresponds to a particular plane cut with at least one glued flap, the cut being made in the material constituting the structure (10) when of the manufacture of the structure (10) folding of the structure (10) from its planar shape is carried out according to the following method:

forming a hollow profile of square shape from the flat shape of the structure (10); - Folding the four flaps of the lower part of the flat shape to form the so-called diamond-shaped bottom surface (102) of the structure (10), this folding naturally forms the volume (100) of octagonal shape structure (10);

- placing and fixing the pocket (1 1, 11a, 11b); and folding the four flaps of the upper portion of the flat shape to form the so-called diamond-shaped top surface (101) of the structure (10).

The unfolding of the structure (10) into a flat shape is carried out according to the following method: unfolding the four flaps forming the so-called top surface (101) in the form of a diamond point;

- removal of the pocket (11, 11 a, 11b);

unfolding the four flaps forming the so-called bottom surface (102) in the form of a diamond point; and - folding the hollow profile to form the planar shape of the structure

(10).

In addition, to facilitate the emptying of the used liquid food during the reprocessing of the used liquid food, the container (1) is designed either so that the structure (10) or the pocket (s) (11) comprise gripping means is so that the pocket (s) (11) are easily extracted from the structure (10) and manipulated to be placed on different systems of emptying pockets (1 1). These gripping means are handles or cutouts adapted to the structure (10) or geometric shapes or thicknesses adapted to the pocket (s) (1 1) for producing suspension devices, for example, at orifices (s) (1 10) of the pocket (s) (1 1). The various bag emptying systems (11) can be made for example by opening a plug, by piercing the bag (11) with a tool to perform a gravity drain, in these first two cases, or made by rolling the flexible bag (11) between two rollers

The present invention also allows a use of the container (1) which allows

- The easy realization of transport operations, storage and transfer of liquid food,

- The removal of the structure (10), in the case where the container (1) is used to transport a fresh liquid food and once the emptying of the fresh liquid food contained in said container is completed, and the folding assembly of the structure (10) of the container (1) before filling used liquid food in the pocket (1 1) of said container (1) to reduce the storage space,

the stacking of the containers (1) after the filling of the pocket (1 1) of the said container (1) to optimize the storage space and the transport of the containers (1) by the transport optimization system to a unit of reprocessing, and

- The easy reprocessing of used food liquid in a reprocessing unit The first use of a single-pouch container (1) consists in draining a used food liquid from a cooking device into the pocket (1 1) of said container (1) by means of a pumping system and after folding assembly of the structure (10) and insertion of the pocket (11) in said structure (10), then transporting said single-pocket container (1) to a storage of the containers (1) or used liquid food and transport, by the transport optimization system, the containers (1) to a used food liquid reprocessing unit

The second use of a single-pouch container (1) consists of filling a cooking device with a fresh food liquid contained in the pouch (1 1) of the container (1) by means of a pumping system, said liquid fresh food being previously transported in the pouch (11) of the container (1) from its place of manufacture to its place of use and which can be stored before use, then once the bag emptied fresh liquid food, drain the used food liquid from the cooking device in the pocket (1 1) of the container (1) by means of a pumping system, then transport said container ( 1) single-pocket to a storage place of the containers (1) or used food liquid and transport, by the transport optimization system, the containers (1) to a used food liquid reprocessing unit, the container ( 1) once empty of fresh liquid food and before filling the used liquid food can be unfolded to optimize the storage space The use of a container (1) bi-pocket is to fill a cooking device of a liquid food fresh water contained in the first pocket of the container (1) by means of a pumping system, said fresh food liquid being previously transported in said first pocket (1 1) of the container (1) of n place of manufacture at its place of use and can be stored before use, then once the first bag emptied fresh liquid food, drain the used food liquid from the cooking device in the second pocket (1 1) of the container (1 ) by means of a pumping system, then transporting said container (1) two-pocket to a place of storage containers (1) or used food liquid and transport, by the transport optimization system, the containers ( 1) to a used food liquid reprocessing unit, the container (1) once emptied of fresh liquid food and before filling the used food liquid can be unfolded to optimize the storage space The container (1) is designed to easily cooperate with a ferry with at least one pumping system

As explained above, the geometry of the container (1), and more particularly of the structure (10) makes it possible to optimize the storage by limiting the space requirement. Most catering establishments encounter difficulties in terms of storage. kitchens are usually arranged optimally and the storage place is weak. The plurality of containers (1) is thus stored by stacking to minimize congestion in the catering establishments.

With reference to FIGS. 4 and 5, the stacking consists of stacking on each other and optimally a plurality of containers (1). The stacking, performed without great positioning effort, can be envisaged on 2 or 3 heights (H) of the container (1) depending on the volume capacity and the ergonomics of each container (1) which allows the manipulation either by a user by other mechanized means of movement assistance.

In the case of an octagonal structure (10), for stacking the containers (1) on each other, it is necessary to slightly rotate an upper container (1b) relative to a container lower (1a) so that the circumference of the bottom surface (102b) of the upper container (1b) comes into contact with the circumference of the top surface (101a) of the lower container (1a). The stacking is carried out for two containers (1 a, 1 b) or on 2 heights (H) container (1). The upper container (1b) is positioned optimally on the lower container (1a). To do this, it is necessary to rotate the upper container (1b) at an angle of substantially 45 ° with respect to the lower container (1a), as shown in Figure 4b. In this way, the circumference of the bottom surface (102b) of the upper container (1b) comes into contact with the circumference of the top surface (101a) of the lower container (1a), as shown in FIG. 4a. The diamond-tipped shape of the top and bottom surfaces (101, 102) of each container (1) drowns the closure system (s) (1 11) of the lower container pocket (1 1). (1a) without it (s) punching (s) the bottom surface (102b) of the upper container (1b), as shown in Figure 5b.

For reasons of food quality, hygiene and safety, the food oil must be renewed after a certain period of use. In this way, a user can fill food liquid or fresh food oil with his cooking device from the container (1) monopoche or two-pocket using means or pumping system cooperating with the openings (1 10, 103) of the structure (10) and the pocket (s) (1 1) as many times as desired and those until the container (1) is empty of any fresh food liquid.

It should be noted that the emptying of the used food liquid from the cooking device in the bag (11) of the container (1) is performed for a used food liquid temperature lower than or equal to the regulated temperature. It is therefore necessary to wait for the cooling of the liquid food to this temperature threshold since the liquid food is used for cooking food at a high temperature. Once the container (1) filled with used liquid food, the container (1) is stored until its collection and transport to units or reprocessing plants, for example, for recycling food oil to biodiesel manufacturing. The transport of the containers (1) is carried out by the transport optimization system and with traditional transport vehicles.

The transport optimization system corresponds to at least one pallet (2) or to suitable means of the "Rolltrainer" type so as to optimize the stacking loading, described above, of containers (1) of liquid food. In a preferred embodiment and with reference to FIG. 6, the transport is carried out by palletizing. This palletizing is carried out on at least one pallet (2) of rectangular shape of length (L), substantially 1200 millimeters, and width (I), substantially 800 millimeters, and the pallet (2) is able to receive a total of 12 containers (1) with 6 containers (1) on a lower level and 6 other containers (1) on a higher level. In this way, the palletization of the containers (1) is optimized and the containers (1) of liquid food are transported in a simple manner.
