Description

Bulk product storage and distribution device

The present disclosure relates to a device for storing and dispensing bulk products, and finds particular application for products in the form of granules, such as dried fruits, legumes, rice, candies, etc., or in the form of powder. This disclosure is, however, not limited to the distribution of foodstuffs.

In a context where consumers are keen to reduce their impact on the environment by generating less waste, there is a growing demand for the distribution of bulk products, and in particular bulk foodstuffs.

Most current solutions are refillable transparent plastic bins, which can for example be suspended with an opening placed under the products to be distributed, and a mechanism allowing the opening to be opened or closed to obtain the products by gravity flow from the products. products. Other solutions include at their base a compartment that can be opened from above so that a user can help themselves using an ad hoc tool.

The disadvantage of this type of solution is on the one hand that plastic containers are currently not recyclable and it is desirable to offer a solution with reduced impact on the environment. In addition, the reusable nature of these containers poses a hygiene problem since they must be cleaned between each filling and the cleaning of the moving parts or mechanisms is often imperfect.

We also know the document FR3105189 which describes a cardboard package comprising an opening arranged in the bottom of the package, this opening being able to be selectively opened or closed by the actuation of a movable shutter element. As this shutter element is located under the bottom of the packaging, and it moves parallel to the bottom of the packaging, the movement of the shutter to release the opening and the distribution of product is done by pulling the shutter towards you, which can cause the entire packaging to move towards the user and therefore the packaging to fall on the user, particularly if the packaging is only slightly reduced. To prevent this movement, it is therefore advisable to hold the packaging in place with the other hand, but this makes it difficult to fill a container positioned under the opening. Furthermore, once the shutter has been moved to allow the products to flow, the consumer has no visibility on the distribution of the product since their sachet must be positioned under the bottom of the packaging, as close as possible to the opening. .

Summary

This disclosure improves the situation.

• un étui destiné à contenir les produits en vrac, comprenant une paroi de fond, un ensemble de parois latérales s’étendant à partir de la paroi de fond, la paroi de fond et l’ensemble des parois latérales définissant entre elles un volume de réception des produits, l’étui comprenant en outre une ouverture de distribution des produits agencée dans l’une des parois latérales,
• une cloison comprenant une ouverture traversante, la cloison étant mobile en translation par rapport à la paroi de l’étui dans laquelle est agencée l’ouverture de distribution des produits, dans une direction parallèle au plan de ladite paroi, de manière à pouvoir adopter au moins une position ouverte dans laquelle l’ouverture traversante est en regard de l’ouverture de distribution de l’étui pour permettre la distribution des denrées, et au moins une position fermée dans laquelle l’ouverture de distribution de l’étui est obturée par la cloison, et
• un organe de rappel élastique de la cloison par rapport à l’étui, adapté pour exercer sur la cloison une force tendant à ramener la cloison dans la position fermée.

A device is proposed for the storage and distribution of bulk products comprising:

• a case intended to contain bulk products, comprising a bottom wall, a set of side walls extending from the bottom wall, the bottom wall and all of the side walls defining between them a receiving volume products, the case further comprising a product distribution opening arranged in one of the side walls,
• a partition comprising a through opening, the partition being movable in translation relative to the wall of the case in which the product distribution opening is arranged, in a direction parallel to the plane of said wall, so as to be able to adopt at at least one open position in which the through opening is opposite the distribution opening of the case to allow the distribution of foodstuffs, and at least one closed position in which the distribution opening of the case is closed by the partition, and
• an elastic return member of the partition relative to the case, adapted to exert on the partition a force tending to return the partition to the closed position.

In embodiments, the elastic return member comprises at least one elastic ring and the case and the partition each include attachment supports for the elastic ring. The attachment supports for the elastic ring can be made respectively in the plane of the partition and in the plane of the wall of the case in which the distribution opening extends. These hanging supports may comprise a first tab arranged in the side wall of the case and a second tab arranged in the partition, the two tabs being aligned according to the direction of movement of the partition and oriented in two opposite directions along said direction.

In embodiments, the case is shaped so that, in use, it is placed on a flat surface, and the bottom wall is then inclined relative to the surface. The angle of inclination of the bottom wall relative to the surface can be between 25° and 40° relative to said surface.

In embodiments, the case is formed of a product storage sheath, and a product distribution sheath, the storage sheath being shaped so that it can be inserted into the distribution sheath.

In embodiments, each sheath comprises a through orifice, and the sheaths are dimensioned so that when the storage sheath is inserted into the distribution sheath, the through orifices face each other and form the dispensing opening of the case. Each sheath can comprise a side wall in which the through hole extends, and the partition can then be shaped to be inserted between said side walls of the two sheaths. The distribution sheath may comprise a set of side walls whose bases extend in the same plane, and the movable partition may comprise an end portion projecting relative to said plane when it is in the closed position in which it closes the dispensing opening, said end portion comprising a gripping member. The movable partition and the distribution sheath may further comprise members for guiding and stopping the movement of the movable partition relative to the distribution sheath.

In embodiments, the distribution sheath may comprise a set of side walls whose bases extend in the same plane and the storage sheath comprises a bottom wall forming the bottom wall of the case, the wall of bottom being inclined relative to the plane formed by the bases of the side walls of the distribution sheath when the internal sheath is inserted there. In this case, the distribution sheath may also include wedges for holding the storage sheath.

In embodiments, the case further comprises a distribution chute extending from the distribution opening, on the exterior face of the side wall carrying this opening, the chute comprising an inclined plane for the flow of the products of decreasing width from the opening. The distribution chute may include conduit surrounding the entire circumference of the distribution opening.

The case, the movable partition and, where applicable, the chute can be made of cardboard.

The proposed device has a distribution opening arranged in one of the side walls of the case, for example at the base of a side wall to allow gravity flow of the products. It also includes a partition movable in translation relative to this side wall, making it possible to selectively close or release the distribution opening. The fact that the dispensing opening is arranged in a side wall of the case and that the partition is movable in a direction parallel to the plane of this wall allows a user to operate the partition without exerting force aimed at pulling the packaging towards him. The risks of the packaging moving and falling are thus reduced.

Furthermore, the proposed device comprises an elastic return means advantageously formed by an elastic ring maintained connected on the one hand to the movable partition and on the other hand to the case. The tensioning of this ring only involves the creation of hooking means on each element (partition and case), which can advantageously be made by cutouts or notches. This means of recall is therefore simple in design and inexpensive to manufacture.

Advantageously, the case of the device can be formed of two sheaths which can be inserted one into the other. The inner sleeve can be pre-filled with products and delivered filled and closed, and inserted into the outer sleeve. This guarantees, particularly in the case where the products are foodstuffs, an absence of handling of the products, and also a limitation of contacts between the products and the movable partition.

The case and the movable partition are for example made of cardboard, or of PE paper comprising 32g of polyethylene per 100g of paper, materials whose recycling is perfectly controlled on an industrial level. In the case where the case is made up of two sheaths, the storage sheath can be single-use and the external sheath can be reused.

Other characteristics, details and advantages will appear on reading the detailed description below, and on analyzing the attached drawings, in which:

With reference to Figures 1, 2a and 2b, we will describe a device 1 for the storage and distribution of bulk products.

This device can in particular be used for the storage and distribution of bulk foodstuffs such as foods in powder form: flour, spices, ground coffee etc., or granular foods such as dried fruits, rice, seeds , lentils or other beans, short pasta, cereal preparations, etc. The device can also be used for the storage and distribution of non-food products, for example in the form of powders (washing powder), flakes or individual elements (flake soap, small mechanical and/or electronic elements such as screws). , bolts, hose fittings etc.).

The device includes a case 10 intended to contain bulk products. The case comprises a bottom wall 11, on which the products rest once the case 10 is filled, and a set of side walls 12 extending from the bottom wall 11 so that the bottom wall and the side walls define between them a volume intended to contain the products. For example, the case 10 may comprise four side walls 12 of substantially parallelepiped shape, extending parallel in pairs. The side walls can extend vertically when the case 10 is placed on a flat and horizontal surface. Alternatively, one or more side walls can extend at an angle with the vertical, for example an angle less than 20°, when the case is placed on a flat and horizontal surface S shown in dotted lines on the . Alternatively, one or more side walls may comprise a portion extending at an angle with the vertical, extended by another portion extending vertically, when the device is placed on a flat and horizontal surface.

The case 10 further comprises a distribution opening 13 arranged in one of the side walls 12, for example a front wall 120, said front wall being intended to be located in front of the user when the device 1 is in use. This distribution opening is advantageously arranged at the base of said side wall, that is to say that the lower edge of the distribution opening is advantageously located at a distance from the lower edge of the side wall of between 0 and 5 cm, preferably between 0 and 2 cm, for example 0 cm, that is to say that the lower edge of the dispensing opening 13 corresponds to the lower edge of the side wall of the case in which it is arranged .

The distribution opening 13 is also dimensioned according to the size of the products to be distributed, to allow simple distribution of the products. The shape of the dispensing opening can be chosen semicircular or more generally comprising a rectilinear base parallel or merging with the lower edge of the side wall in which it is formed, and a convex contour connecting the two ends of this base.

The device 1 further comprises a movable partition 20 in translation relative to the side wall 12 of the case in which the product distribution opening 13 is arranged. The movable partition comprises a through opening 23 which may have a shape and dimensions identical to the distribution opening 13 of the case. The movable partition 20 is adapted to be moved in a plane parallel to the plane of the wall 12 in which the distribution opening 13 is arranged so as to be able to adopt at least one position in which the through opening 23 is facing the dispensing opening 13, thus corresponding to an open configuration of the device 1 shown in Figures 1 and 2b, in which the products can exit the case through the two openings, and at least one other position in which the opening distribution 13 of the case is closed by the partition, corresponding to a closed configuration of the device 1 shown on the , in which the products cannot exit the case through these openings.

The movable partition and the case are for example shaped to allow movement of the movable partition in a vertical direction.

The movable partition 20 advantageously comprises a gripping member 24 allowing it to be operated by a user. This gripping member 14 can for example be a handle formed by a cutout in the movable partition, in which the user can put his fingers to exert traction on the partition 20.

The device 1 further comprises an elastic return member 30 of the partition 20 relative to the case 10, adapted to exert on the partition a force tending to return the partition to the second position, to thus close the dispenser. In this way, the device 1 can be used by a user by moving the movable partition 20 to bring the through opening 23 opposite the distribution opening to allow the distribution of the products, then, by releasing the force exerted on the movable partition, it returns to the closed position under the effect of the restoring force exerted by the elastic return member 30.

The elastic return member 30 comprises one or more elastic rings, for example one or more rubber rings whose dimensions are adapted to those of the device 1 so that in the open configuration, the ring is stretched relative to the size that it presents in the absence of mechanical stress. The elastic ring(s) cooperate with hooking supports 15, 25 arranged respectively on the movable partition 20 and the case 10, and shaped to each retain one end of an elastic ring. The hanging support 15 of the case can be arranged in the side wall in which the distribution opening is arranged. Alternatively, the hanging support may be formed of one or more notches formed in the side walls adjacent thereto.

In a particular embodiment, an example of which is illustrated in Figures 2a and 2b, the hooking supports 15, 25 are formed respectively in a wall of the case and in the movable partition and extend in the plane of the wall and partition, without protruding from this wall, in order to reduce the bulk associated with the supports. For example, the hanging supports 15, 25 can each be formed of a tab cut respectively in the side wall 120 of the case in which the distribution opening is arranged, and in the movable partition 20. The tabs are aligned in the direction of movement of the partition and oriented in opposite directions so as to be able to hook the two ends of an elastic ring. In the example shown in Figures 2a and 2b, the tab 15 of the case 10 is a tab formed by a cutout of the upper edge of the side wall of the case comprising the distribution opening, this tab being oriented towards the top, that is to say that the tongue is connected to the side wall by its lower end, and the tongue 25 of the movable partition is a tongue delimited by a curvilinear opening made in the partition 20, the tongue being oriented down. An inverted configuration in which the tongue 25 of the partition is made in an upper edge of the partition, and a tongue 15 extending downwards is made in the side wall of the case is also possible.

To allow the distribution of products when the movable partition 20 is in the open position, the bottom wall 11 on which the products are arranged extends along a plane inclined relative to a flat surface S, and preferably horizontal, on which the device can be installed. The angle formed by the bottom wall relative to the surface on which the device can be placed is advantageously between 25° and 40°.

The device 1 may further comprise a distribution chute 40 capable of being attached to the case 10 so as to extend from the distribution opening 13, on the exterior face of the side wall carrying this opening, in forming an inclined plane 41 for the flow of products of decreasing width from the distribution opening. The inclined plane therefore extends from the base of the dispensing opening 13 in continuity therewith to prevent products from passing between the case 10 and the inclined plane. This distribution chute 14 can thus guide the products distributed towards a bag used by the user. The distribution chute 14 can also form a conduit extending around the entire circumference of the opening, which improves the hygiene of the device because it prevents dust or dirt from being deposited on the inclined plane in contact with the products. . We represented on the an example of a blank allowing such a distribution chute to be produced, the chute being able to be assembled to the case using suitable tabs and notches, or alternatively being able to be stuck to the sheath using glue or adhesive tape.

The case 10 of the device 1 described above can be formed of two sheaths which can be inserted into each other, comprising a storage sheath 16 for the products and a distribution sheath 17 for the products, the storage sheath 16 being inserted in the distribution sheath.

We represented on the an example of a blank that can be used to mount a distribution sheath 17, on the an example of a blank that can be used to mount a storage sheath 16 and on the an example of a blank that can be used to make a movable partition 20.

The storage sheath 16 can be adapted to form a closed volume for storing the products, comprising the bottom wall 11 of the device, side walls 160 extending from the bottom wall, and an upper wall opposite the wall bottom and connecting the side walls together so as to close the storage volume of the products. One of the side walls, for example a front wall 161, intended to face a user when using the device, may comprise at its base a zone of weakness 162 allowing, during the first use of the storage sheath , to cut out a through orifice 163 forming part of the distribution opening 13 of the device described above.

As indicated above, the bottom wall 11 of the device 1 is advantageously inclined relative to the surface on which the device is placed; in this regard, the side walls 160 of the storage sheath extending on either side of the front wall 161 advantageously have a trapezoidal shape.

The distribution sheath 17 can for its part be formed of a set of side walls 170, the bases of which delimit a flat lower edge capable of resting on a flat surface. In particular, the side walls 170 of the distribution sheath 17 may be rectangular, and the distribution sheath 17 may not include a bottom wall since the bottom wall 11 of the device is formed by the bottom wall of the storage sheath.

The dispensing sheath 17 also comprises, on a side wall 170, for example a front wall 171 (i.e. a wall facing the user when the device 1 is used) a through orifice 173. The two sheaths 16, 17 are shaped so that, when the storage sheath 16 is inserted into the distribution sheath 17, the two through orifices 163, 173 come opposite each other and thus jointly form the distribution opening 13 of the device 1 In this regard, if as indicated previously the dispensing opening 13 extends from a lower edge of the side wall 12 of the device in which it is arranged, the through orifice 173 of the dispensing sheath can be formed of a notch extending from a lower edge of the corresponding side wall of the sheath 17. The through orifice 163 of the storage sheath can also be formed from the lower edge of the corresponding side wall of this sheath.

When the storage sheath 16 has two trapezoidal side walls 160 to give an inclination to the bottom wall, the device 1 advantageously comprises at least one wedge 175 making it possible to maintain the storage sheath 16 in position in the distribution sheath 17. The distribution sheath 17 can for example comprise a wedge 175 adapted to maintain one end of the bottom wall opposite the distribution opening, and/or a wedge 175 'adapted to maintain one end of the bottom wall located on the side of the distribution opening.

In reference to the and to the , the wedge 175 maintaining the end of the bottom wall opposite the dispensing opening can be formed in the dispensing sheath 17, for example by a first strip 175 of the dispensing sheath extending from an adjacent side wall to the front wall to another side wall opposite the front wall, this strip being cut on its horizontal sides, ie parallel to the lower and upper edges of the sheath, but being connected to the walls of the sheath by its vertical edges, so as to be able to be folded towards the inside of the sheath 17 when the latter is mounted, the strip thus forming a right-angled corner projecting towards the inside of the sheath, on which the bottom wall 11 of the storage sheath can rest. The wedge 175' maintaining the end of the bottom wall located on the side of the distribution opening can be formed by a strip of material 175' connecting together the side walls 170 adjacent to the front wall and on which can be placed the back wall.

When the case 1 is formed of two sheaths 16, 17, the movable partition 20 is shaped to be inserted between the side walls of the two sheaths carrying the through hole of each sheath, and to be able to be moved in the gap between these walls. In particular, the movable partition may have a substantially rectangular shape, and be movable parallel to the main direction of the partition. On the which represents an example of a blank for making this partition, we understand that the partition is obtained by folding three substantially identical layers of material, typically cardboard, which makes it possible to give more rigidity to this partition. The cutouts corresponding to the orifice 23, the handle 24 and the notch for hanging the elastic 25 therefore appear in each layer.

• la position ouverte dans laquelle l’ouverture traversante 23 de la cloison est alignée avec les ouvertures traversantes 163,173 des fourreaux, et
• la position fermée dans laquelle l’ouverture traversante 23 de la cloison est intégralement obturée par les parois des fourreaux, et les ouvertures des fourreaux sont également obturées par une portion pleine de la cloison mobile.

The distribution sheath 17 and the movable partition 20 advantageously comprise guide and stop members 176, 26 for the movement of the movable partition 20. For example, the movable partition 20 may comprise protrusions 26 projecting relative to the rectangular edge of the partition, and the distribution sheath 17 may include cutouts 176 adapted to receive said protrusions 26, the length of the cutouts in the direction of movement of the movable partition corresponds to the length of the distance traveled by the movable partition between:

• the open position in which the through opening 23 of the partition is aligned with the through openings 163,173 of the sheaths, and
• the closed position in which the through opening 23 of the partition is completely closed by the walls of the sleeves, and the openings of the sleeves are also closed by a solid portion of the movable partition.

The movable partition 20 is advantageously shaped to include an end portion 27 projecting relative to the lower plane edge delimited by the bases of the side walls of the distribution sheath 17, whether in the open position or in the closed position, this end portion comprising the gripping handle. Thus, the device 1 can be positioned on a flat surface S, preferably horizontal, so that the end portion 27 extends to the right of the edge of this surface and can therefore extend under the plane of the surface. The gripping handle carried by the end portion 27 is then clearly visible to the user, who can pull it downwards to cause the device to open and the products to be distributed.

Preferably, the device 1 is made entirely of recyclable material, for example cardboard or PE paper comprising 32g of polyethylene per 100g of paper, with the exception of the elastic ring(s) forming the return members of the movable partition. In particular, the case, the movable partition and the distribution chute are advantageously made of these materials. When the case is made up of two sheaths, the distribution sheath can be reused with another storage sheath when the products contained in the previous storage sheath are used up.
