Description

Technical Field

[0001] The present invention is in the field of bulk product dispensing and metering systems for bulk food and / or beverage products.

[0002] In particular, the present invention relates to a bulk metering unit for dispensing and metering a bulk product stored in a bulk product container. Further, the present invention relates to a bulk product container for storing bulk food and / or beverage products. Finally, the present invention relates to a bulk metering system combining the bulk metering unit and the bulk product container.

[0003] For the purposes of this specification, "food" is intended to include any solid substance that can be ingested by humans, and "beverage" is intended to include any liquid substance that can be ingested by humans. These are ingested as such, or in combination with other elements, or after a particular process has been applied.

Background Art

[0004] Bulk food and / or beverage products are items that are provided in large volumes and can be purchased in large bulk lots or transferred from a bulk container to smaller containers for the purpose of purchase. Bulk food and / or beverage products are typically packaged in large, common bulk containers and packaging for grocery stores, which can be less expensive compared to packaged foods since they utilize fewer natural resources. In this regard, bulk products allow for the use of less packaging and are thus more environmentally friendly and sustainable.

[0005] Reducing packaging waste and improving quantity control, and ultimately preventing food and / or beverage waste, are challenges for bulk products, particularly those typically packaged in heavy packaging (such as cardboard boxes, thick plastic jugs, and glass bottles). Consumers, in particular, can purchase bulk products at a lower price and in desired quantities rather than fixed, predetermined amounts, compared to pre-packaged versions of the same product.

[0006] Dispensing of bulk products is typically done from bulk containers defined by open-top bottles that store the bulk products being dispensed, and these open-top bottles are equipped with scoops that allow for manual volume adjustment.

[0007] To avoid direct interaction between the user and the bulk products stored in the bulk container, gravity-driven containers are known, which are operated by a lever that activates the gravity-driven dispensing of the bulk products.

[0008] Known bulk dispensing systems operate using standard canisters, requiring retailers to manually fill the canisters with products, compromising traceability and making product handling cumbersome. The entire process is time-consuming and should be improved. Furthermore, these bulk dispensing systems require regular cleaning to prevent contamination of the system's appearance and to avoid hygiene issues, a problem that becomes more pronounced when the bulk dispensing system stores bulk food and / or beverage products that meet food safety requirements.

[0009] U.S. Patent Application Publication No. 2012104041(A1) describes a beverage dispenser comprising a beverage bag suspended within the volumetric section of the dispenser itself. A valve mechanism is fluidly coupled to the inside of the bag and configured to selectively dispense the beverage from the bag. Furthermore, a movable press is provided within the volumetric section below the bag, and together with a spring, presses the bag upward. The spring elastically biases the press toward the volumetric section.

[0010] This dispenser allows for the use of certain container products, which can also improve the traceability, cleaning, and safety of the dispensed product. Nevertheless, this dispenser requires a complex structure in which the bag must be suspended within the dispenser's volumetric section to enable proper function. Furthermore, the specific structure of this dispenser does not allow for the handling of solid or powder-type bulk products.

[0011] Therefore, it is desirable to provide alternative solutions to assist in dispensing products that can minimize the aforementioned drawbacks. In particular, it is desirable to have a bulk dispenser that can provide precise volume control for solid or powder-type bulk products. Furthermore, it is desirable to have a bulk dispenser that can ensure better protection of the dispensed product and limit safety issues related to contact. [Overview of the Initiative]

[0012] The object of the present invention is to provide a bulk dispenser that can minimize the aforementioned drawbacks.

[0013] In particular, an object of the present invention is to provide a bulk dispenser that can enable multiple precise dispensing of powdered or solid food and / or beverage bulk products from a flexible bulk product container.

[0014] Another object of the present invention is to provide a bulk dispenser that enables the loading and unloading of bulk product containers without the user having to come into contact with the products stored in the bulk product containers.

[0015] The above-mentioned objectives are achieved by the bulk volume adjustment unit described in the attached claims.

[0016] The bulk volume adjustment unit is A housing that defines a storage volume for receiving bulk product containers, A dispensing opening defined in the housing for dispensing bulk products, A supply assembly that is at least partially located inside the housing and can move the bulk product in the bulk product container toward the dispensing opening, It comprises a volume adjustment device that can be operated to dispense and adjust the volume of bulk products, The volume adjustment device comprises a volume adjustment element and a sliding assembly, the sliding assembly being an assembly for sliding the volume adjustment element between a closed position where no bulk product is dispensed and a maximum dispensing position where the bulk product can be dispensed at the maximum flow rate, and also in the reverse direction, at the dispensing opening. The volume adjustment device comprises one or more device engagement parts that are positioned toward the storage volume section and can engage with the opening cover of the bulk product container. The volume adjustment element has at least one opening, In the closed position, the opening portion can be positioned away from the container opening of the bulk product container, and at the same time, the device engagement portion can position the opening cover of the bulk product container in a fully closed position that completely covers the container opening of the bulk product container, and in the maximum dispensing position, the opening portion can be superimposed on the container opening of the bulk product container, and at the same time, the device engagement portion can position the opening cover of the bulk product container in a fully open position that substantially completely exposes the container opening of the bulk product container, thereby enabling adjustment of the bulk product quantity according to the position of the quantity adjustment element between the closed position and the maximum dispensing position.

[0017] The dispensing device allows for precise dispensing of bulk products from bulk product containers, enables users to avoid contact with the bulk products themselves, and ensures better protection of the bulk products from the environment (i.e., humidity, oxygen, dust, etc.) when not being dispensed. The dispensing device also allows for easy dispensing by controlling the opening cover, i.e., controlling the area of ​​the container opening opened by acting on the opening cover.

[0018] In one embodiment, the volume adjustment element has a covering portion and an opening portion arranged side by side. In the closed position, the covering portion can be superimposed on the container opening of the bulk product container, and at the same time, the device engaging portion can position the opening cover of the bulk product container in a fully closed position that completely covers the container opening of the bulk product container. In the maximum dispensing position, the opening portion can be superimposed on the container opening of the bulk product container, and at the same time, the device engaging portion can position the opening cover of the bulk product container in a fully open position that substantially completely exposes the container opening of the bulk product container, allowing for adjustment of the bulk product quantity depending on the position of the quantity adjustment element between the closed position and the maximum dispensing position.

[0019] The volume adjustment element, which includes a covering portion and an opening portion, allows for constant control of the opening cover of the bulk product container, and the covering portion can maintain contact with the opening cover.

[0020] In one embodiment, the housing includes a door that allows access to the storage volume, The volume adjustment device is located on the door.

[0021] The door allows access to at least one opening and also allows for the placement of the entire dispensing device. In this respect, the loading and unloading of bulk product containers is simplified.

[0022] In one embodiment, the volume adjustment element comprises at least one of the device engagement portions, and / or the sliding assembly comprises at least one of the device engagement portions.

[0023] The device engagement portion allows the bulk volume adjustment unit to operate relative to the opening cover of the bulk product container when the volume adjustment device is activated, ensuring not only proper volume adjustment of the bulk product but also proper protection.

[0024] In one embodiment, the metering device is arranged outside the storage volume and comprises a lever that enables the user to operate the sliding assembly at least from the closed position to the maximum dispensing position.

[0025] In this way, the user can dispense the bulk product in a simple and effective manner while controlling the metering of the bulk product.

[0026] In one embodiment, the sliding assembly comprises one or more elastic elements connected to the metering element in order to arrange the metering element in the closed position when the sliding device is not actuated.

[0027] In this way, the metering device ensures the protection of the bulk product and at the same time avoids overfilling of the bulk product.

[0028] In one embodiment, the metering element further comprises a nozzle part at the opening part.

[0029] This makes it possible to define a single element that contacts the bulk product from metering to dispensing.

[0030] In one embodiment, the supply assembly comprises at least one plate that can move and / or compress a bulk product container arranged on or in contact with the plate. In the storage volume, the plate is arranged inside the storage volume to maximize the volume available for the bulk product container inside the storage volume, preferably substantially on the side of the storage housing inside the storage volume, in a stationary position, and the plate is arranged inside the storage volume to minimize the volume available for the bulk product container inside the storage part, preferably spaced from the side of the storage housing inside the storage volume and parallel or inclined to the side, and is movable between a maximum displacement position.

[0031] The plate assists in dispensing operations by enabling an easy method to remove bulk products almost completely from bulk product containers.

[0032] Furthermore, by positioning the plate on the side of the housing, it becomes possible to reduce the complexity and footprint of the bulk volume adjustment unit.

[0033] In one embodiment, the supply assembly further comprises a pressing device operably connected to the plate for pressing the plate toward the maximum displacement position.

[0034] The pressing device maintains the bulk product container in a preferred position for dispensing and presses the bulk product toward the container opening.

[0035] In one embodiment, the supply assembly further comprises a locking device operably connected to the plate and the door, The locking device comprises a locking mechanism located inside the housing in a stationary position for locking the plate in a stationary position, and an unlocking mechanism operably connected to the locking mechanism and positioned to at least partially contact the door for unlocking the plate from the stationary position when the door is closed.

[0036] In this way, the locking mechanism allows for easy loading of bulk product containers into the storage volume, reducing the effort required from the operator. Furthermore, this unlocking mechanism allows the plate to be automatically positioned for dispensing without any intervention from the operator.

[0037] In one embodiment, the housing further includes a locking device for the bulk product container opening frame, which can firmly maintain the position of the bulk product container opening relative to the housing while the volume adjustment device is in operation.

[0038] This ensures the secure positioning of bulk product containers and guarantees the smooth operation of the volume adjustment device.

[0039] In a further embodiment, an object of the present invention is to provide a bulk product container that can minimize the aforementioned drawbacks.

[0040] In particular, an object of the present invention is to provide a bulk product container that allows the bulk product container to be loaded and unloaded without the user having to come into contact with the product stored in the bulk product container, and that enables multiple precise adjustments of the quantity of powdered or solid food and / or beverage bulk products.

[0041] The above-mentioned objectives are achieved by the bulk product container described in the attached claims.

[0042] Bulk product containers are A volume defined by a closed enclosure for storing bulk food and / or beverage products, The container opening defined in the outer enclosure, An opening frame is positioned at the container opening to define the container opening, It comprises an opening cover movably coupled to an opening frame for covering or exposing the container opening, The opening cover is movable relative to the opening frame from a fully closed position that completely covers the container opening to a fully open position that substantially completely exposes the container opening. The opening cover comprises one or more container engaging portions that can be engaged by the volume adjustment device of the bulk volume adjustment unit according to the present invention in order to position the opening cover between a fully closed position and a fully open position.

[0043] The opening cover ensures that the bulk product contents are always protected when dispensing is not required. In particular, a container engagement portion provided on the opening cover allows the opening cover to be moved by a corresponding actuator in the bulk volume adjustment unit, which is defined by the device engagement portion of the bulk volume adjustment unit according to the present invention. Precise volume adjustment is easily performed according to the area of ​​the container opening opened by the opening cover.

[0044] In a further embodiment, the opening frame comprises one or more rail guides, and the opening cover comprises one or more guide elements that fit onto the rail guides and allow the opening cover to slide relative to the opening frame.

[0045] The presence of rail guides and guide elements allows the opening cover to slide over the container opening, thus maintaining good protection of the bulk product.

[0046] In a further embodiment, the internal volume is depressurized to reduce the volume of the enclosed enclosure until the container opening is first opened.

[0047] This reduces the volume, which in turn makes it easier to fit the bulk product container into the storage volume section of the bulk volume adjustment unit during the loading operation.

[0048] In a further embodiment, an object of the present invention is to provide a bulk volume adjustment system that can minimize the aforementioned drawbacks.

[0049] In particular, an object of the present invention is to provide a bulk quantity adjustment system that allows for loading and unloading of bulk product containers without the user having to touch the products stored in the bulk product containers, and that enables multiple precise quantity adjustments of powdered or solid food and / or beverage bulk products.

[0050] The above-mentioned objectives are achieved by the bulk quantity adjustment system described in the attached claims.

[0051] The bulk quantity adjustment system comprises a bulk quantity adjustment unit according to one embodiment of the present invention and a bulk product container according to one embodiment of the present invention, wherein the bulk product container is housed within a housing.

[0052] In this way, the bulk volume adjustment unit and the bulk product container according to the present invention can cooperate to maximize their effects, with one part, namely the bulk volume adjustment unit, referring to the cooperating part, namely the bulk product container, and vice versa.

[Modes for carrying out the invention]

[0054] Referring to Figures 6, 7A, and 7B, a bulk product container 10 according to a preferred embodiment of the present invention is shown and described herein.

[0055] The bulk product container 10 described above can cooperate with the bulk quantity adjustment unit 100, as shown in Figures 1 to 5 according to a preferred embodiment of the present invention.

[0056] The combination or cooperation of the bulk product container 10 and the bulk quantity adjustment unit 100 defines the bulk quantity adjustment system 1, as shown in Figures 8 to 14 according to a preferred embodiment of the present invention. In this way, the bulk quantity adjustment unit 100 and the bulk product container 10 of the present invention can cooperate to maximize their effects.

[0057] In the following, we will refer to the case where one part, namely the bulk quantity adjustment unit 100, works in cooperation with the other part, namely the bulk product container 10, and vice versa, but each part can be defined separately without incorporating the other in order to define its inventive concept.

[0058] Figure 6 shows a bulk product container 10 in a preferred embodiment of the present invention. The perspective view of Figure 6 shows the bulk product container 10 as comprising a closed enclosure 13 that can define an internal volume (not shown) for storing bulk food and / or beverage products (not shown). Preferably, the bulk product is filled after the closed enclosure 13 has been partially formed in a process known as foam-fill sealing, which seals the enclosure at the end of filling and defines the closed enclosure 13. Different methods can be used to define the closed enclosure.

[0059] In a preferred embodiment, the bulk product container 10 is flexible or compressible, meaning that the enclosed enclosure 13 is made of a flexible or compressible material. Plastic, paper, or multilayer materials, i.e., materials that combine sheets or parts such as plastic, paper, and aluminum, are suitable for defining the enclosed enclosure 13.

[0060] As shown in the figure, the enclosure 13 has a parallelepiped shape, which may vary according to further embodiments (not shown) based on the dimensions and shape of the enclosure itself or based on the dimensions, shape, and volume of its bulk contents.

[0061] To enable a reduction in the volume of the enclosed enclosure 13, the internal volume can preferably be reduced after or during filling with the bulk product to be contained. While this feature is not essential to the present invention, it helps to facilitate fitting the bulk product container 10 into the bulk volume adjustment unit 100 during the loading operation, as will be described in more detail below. Furthermore, the reduced internal volume simplifies transportation operations and reduces associated costs. The reduced volume of the enclosed enclosure 13 is maintained until the container opening 11 is first opened, after which the volume can be expanded by the flexibility or compressibility of the enclosed enclosure 13 or maintained by the bulk volume adjustment unit 100 after its insertion.

[0062] The bulk product container 10 thus includes a container opening 11 defined in a closed enclosure 13. In this embodiment, such a container opening 11 is defined in one of the thickest side walls of the closed enclosure 13 and is located at the bottom of the enclosure, allowing the maximum amount of bulk product to be dispensed by gravity and significantly reducing leftover.

[0063] According to another embodiment not shown, the container opening may be defined by another part of the same wall, i.e., the top but a part that reduces the use of gravity to allow pouring, or by another wall of the enclosed enclosure, i.e., the bottom wall where the effect of gravity on pouring may be even greater.

[0064] To maintain the enclosure 13 in a closed state before initial use, an opening membrane 15 is provided, preferably to keep the container opening 11 tightened, and preferably to seal onto the opening frame 14. Such an opening membrane 15 is preferably airtight to preserve the bulk contents in the bulk product container 10. This opening membrane 15 can be made of any material that enables the closure of the container opening 11 and the protection of the contents. Furthermore, such an opening membrane 15 is of a flexible type, but a rigid or semi-rigid opening membrane can be used.

[0065] When the bulk product container 10 is operated for dispensing, the opening membrane 15 is pulled away to open the container opening 11 upon first use. The sequence in Figures 6 and 7A clearly shows the removal of the opening membrane 15, which is pulled upward for removal.

[0066] To complete the bulk product container 10 according to the present invention, two additional elements are provided on the enclosed enclosure 13, which are an opening frame 14 and an opening cover 12. These elements are preferably made of plastic or metal material and provide rigid elements to the enclosed enclosure. According to further embodiments, any suitable material can be used.

[0067] The opening frame 14 is positioned around the container opening 11 and defines the opening. The dimensions of the opening frame 14 are such that the frame defines the boundary around the container opening 11 while allowing full access to the opening. Preferably, the opening frame 14 has dimensions slightly larger than the container opening 11, but it can also be used with much larger dimensions.

[0068] The opening cover 12 is coupled to the aforementioned opening frame 14 so as to be movable, preferably sliding on the opening frame 14 relative to the container opening 11, and is therefore configured as a slider in a preferred embodiment. The opening cover 12 has dimensions that allow it to fit completely onto the opening frame 14, but according to further embodiments (not shown), a larger opening cover 12 can be used. This allows the opening cover 12 to cover or expose the container opening 11 as needed to pour bulk product from the bulk product container 10 and adjust the volume. Since the opening cover 12 covers the container opening 11 of the enclosed enclosure 13, it prevents food and / or beverage products from spilling out of the internal volume of the bulk product container 10.

[0069] Furthermore, the opening cover 12 is preferably removable from the opening frame 14, which allows the same opening cover 12 to be used and reused for multiple bulk product containers 10.

[0070] The opening frame 14 is equipped with rail guides positioned along its side walls, and the opening cover 12 is equipped with a pair of guide elements positioned on its sides that fit into the rail guides of the opening cover 12. The combination of rail guides and guide elements allows the opening cover 12 to slide relative to the opening frame 14, thus defining not only the opening and closing of the container opening 11 but also the adjustment of the amount between these positions, which will be described in more detail later.

[0071] Further embodiments (not shown) can provide different numbers or arrangements of rail guides and guide elements.

[0072] The presence of rail guides and guide elements allows the opening cover 12 to slide over the container opening 11, thus maintaining good protection of the bulk product. Similarly, different technical solutions known in the art can be provided to enable the sliding of the opening cover as described above.

[0073] In this regard, Figure 7A shows a perspective view of the bulk product container 10 with the opening cover 12 in the fully closed position, in which case the opening cover 12 completely covers the container opening 11. Figure 7B shows a perspective view of the bulk product container of Figure 6 with the opening cover 12 in the fully open position, in which case the opening cover 12 completely exposes the container opening 11. In the fully open position, the opening cover can also be designed to substantially completely expose the container opening, with the aim of exposing the container opening to a degree that allows for a large flow rate while minimizing the residual amount to a predetermined level.

[0074] Therefore, when dispensing is not required, the opening cover 12 can always protect the contents of the bulk product. In particular, after the opening membrane 15 is removed, the contents are no longer sealed within the enclosed container 13 and are exposed to the environment, so protection of the bulk product is necessary.

[0075] Therefore, the opening cover 12 is movable relative to the opening frame 14 from a fully closed position that completely covers the container opening 11 to a fully open position that (substantially) completely exposes the container opening 11. In this regard, the opening cover 12 includes one or more container engaging portions 12', 12'' that can be engaged by the volume adjustment device 120 of the bulk volume adjustment unit 100 (described in detail below) to position the opening cover 12 between the fully closed position (Figure 7A) and the fully open position (Figure 7B).

[0076] In particular, the container engagement portions 12' and 12'' provided on the opening cover 12 allow the opening cover 12 to be moved by corresponding actuators in the bulk volume adjustment unit 120, which are defined by the device engagement portions of the bulk volume adjustment unit 120 according to the present invention. Precise volume adjustment is easily performed according to the area of ​​the container opening 11 opened by the opening cover 12, with a larger area resulting in a larger dispensing flow rate.

[0077] Figure 1 shows the bulk volume adjustment unit 100 in an open and partially detached configuration in a preferred embodiment of the present invention. The perspective view of Figure 1 shows the bulk volume adjustment unit 100, i.e., the bulk product contained in the bulk product container 10 as described above, comprising a housing 110 that defines a storage volume section for receiving the bulk product container 10. The capacity and shape of the storage volume section must be at least equal to the volume and shape of the bulk product container 10 to be contained, and in a preferred embodiment, the storage volume section has a larger volume than the bulk product container 10 and also has the same shape.

[0078] The housing 110 defines the frame for the bulk dispensing unit 100. The housing 110 is shown with the side panels removed so that the internal space defined by the housing volume can be viewed in detail. According to further embodiments (not shown), the housing may not have side panels at all, and the support of the bulk product container is easily achieved by rods interconnecting parts of the same frame, or by the rigidity and shape of the bulk product container itself.

[0079] A dispensing opening 112 is defined on the housing 110. In particular, this dispensing opening is defined on one of the thick side walls of the housing 110 so as to coincide with the container opening 11 of the bulk product container 10. Thus, the dispensing opening 112 allows for the dispensing of the bulk product, which is consequently dispensed from the container opening 11. According to further embodiments (not shown), the position and size of the dispensing opening may vary depending on the position and size of the container opening, and vice versa.

[0080] The dispensing opening 112 has dimensions larger than the container opening 11, and in this regard, as will be described in more detail herein, it allows the volume adjustment element 121 to move relative to the container opening 11.

[0081] A volume adjustment device 120 is provided and is operable to dispense and adjust the volume of bulk products, particularly bulk products contained in bulk product containers 10. The volume adjustment device 120 comprises a volume adjustment element 121 and a sliding assembly 122 operably coupled to each other, the sliding assembly allowing the volume adjustment element 121 to slide in the dispensing opening 112. In this embodiment, the volume adjustment element 121 and the sliding assembly 122 are made separately to allow for easy and effective cleaning, in which case the volume adjustment element 121 is the only element of the volume adjustment device 120 that may come into contact with the bulk product being dispensed. According to another embodiment not shown, the volume adjustment element and the sliding element are made as a single piece or are firmly connected to each other.

[0082] The sliding movement of the volume adjustment element 121 is defined between a closed position where no bulk product is dispensed and a maximum dispensing position where the bulk product can be dispensed at the maximum flow rate, and also in the reverse direction.

[0083] The volume adjustment device 120, as a preferred solution, includes a lever 124 located outside the volume storage section, which allows the user to operate the sliding assembly 122 from at least the closed position to the maximum dispensing position; however, different elements may be used to support the operation. In this embodiment, the lever 124 is part of the door 113 (detailed below) and is located outside the door 113, exposed to the outside of the bulk volume adjustment unit 100.

[0084] In this way, users can dispense bulk products in a simple and effective manner while controlling the quantity of the bulk product.

[0085] The volume adjustment device 120 is provided with multiple device engagement parts 123', 123'', which enable engagement with the opening cover 12 of the bulk product container 10, as described above.

[0086] In this embodiment, the volume adjustment element 121 has a covering portion 121' and an opening portion 121'' arranged side by side. Thus, the volume adjustment element 121 can be substantially defined by a plate having a covering portion 121', i.e., a solid portion, in part and an opening portion 121'', i.e., a portion with an opening, in the other part, with the opening portion 121'' arranged side by side with the covering portion 121'. The volume adjustment element 121 is designed to interact with the opening cover 12 and the bulk product being dispensed. In this regard, the covering portion 121' can therefore remain in contact with the opening cover 12. In the preferred embodiment shown herein, the volume adjustment element 121 also has a nozzle portion 121''' in the opening portion 121'', thereby defining a single element that contacts the bulk product from volume adjustment to dispensing. A nozzle cover 141 is also provided coupled to the housing 110 to at least partially cover the nozzle portion 121'' and to prevent the nozzle portion from coming into contact with the user. In this embodiment, the nozzle cover 141 is located on the door 113 of the bulk volume adjustment unit 100, specifically on its exterior. The nozzle cover is not essential to the present invention and, therefore, may not be part of the bulk volume adjustment unit according to further embodiments not shown.

[0087] In the closed position, the covering portion 121' can be superimposed on the container opening 11 of the bulk product container 10, and at the same time, the device engaging portion 123'' can position the opening cover 12 of the bulk product container 10 in a fully closed position that completely covers the container opening 11 of the bulk product container 10. In the maximum dispensing position, the opening portion 121'' can be superimposed on the container opening 11 of the bulk product container 10, and at the same time, the device engaging portion 123'' can position the opening cover 12 of the bulk product container 10 in a fully open position that substantially completely exposes the container opening 11 of the bulk product container 10, allowing for adjustment of the bulk product quantity depending on the position of the quantity adjustment element 121 between the closed position and the maximum dispensing position.

[0088] In further embodiments not shown, the volume adjustment element may have at least one opening, meaning it may also consist of only an opening. In this last embodiment, in the closed position, the opening can be positioned away from the container opening of the bulk product container, and at the same time, the device engagement portion can position the opening cover of the bulk product container in a fully closed position that completely covers the container opening of the bulk product container. Furthermore, in the maximum dispensing position, the opening can be superimposed on the container opening of the bulk product container, and at the same time, the device engagement portion can position the opening cover of the bulk product container in a fully open position that substantially completely exposes the container opening of the bulk product container, thereby enabling volume adjustment of the bulk product depending on the position of the volume adjustment element between the closed position and the maximum dispensing position.

[0089] The perspective view in Figure 2 provides a better view of the volume adjustment device 120, particularly the device engagement portions 123' and 123''. According to the preferred embodiment shown herein, the volume adjustment element 121 is provided with one of the device engagement portions specifically indicated by number 123' in Figure 2, and the sliding assembly 122 is provided with a pair of device engagement portions specifically indicated by number 123'' in Figure 2.

[0090] The device engagement portions 123' and 123'' allow the bulk volume adjustment unit 100 to operate relative to the opening cover 12 of the bulk product container 10 when the volume adjustment device 120 is activated, ensuring not only proper volume adjustment of the bulk product but also proper protection. In this embodiment, the device engagement portion 123' provided on the volume adjustment element 121 is designed to allow the opening cover 12, and thus the container opening 11, to be opened, while the device engagement portion 123'' provided on the sliding assembly 122 is designed to allow the opening cover 12 to be closed. Different (or reversed) arrangements of the device engagement portions may also be provided.

[0091] In further embodiments (not shown), the volume adjustment element may comprise at least one of the device engagement portions, and / or the sliding assembly may comprise at least one of the device engagement portions. Furthermore, the volume adjustment device may comprise even a single device engagement portion.

[0092] The aforementioned device engagement portions 123' and 123'' are positioned toward the storage volume portion and therefore face the bulk container 10 or have projections facing it. Thus, the device engagement portions 123' and 123'' can engage with the opening cover 12 of the bulk product container 10. In particular, the device engagement portion 123' provided on the volume adjustment element 121 is designed to engage with a corresponding container engagement portion 12' located on the upper part of the opening cover 12, which has a similar shape and size, while the device engagement portion 123'' provided on the sliding assembly 122 is designed to engage with a corresponding container engagement portion 12'' located on the side of the opening cover 12. According to further embodiments (not shown), different arrangements and shapes can be provided for the device engagement portions and the container engagement portions.

[0093] The volume adjustment device 120 enables precise volume adjustment of bulk product from bulk product container 10, allows the user to avoid contact with the bulk product itself, and ensures better protection of the bulk product from the environment (i.e., humidity, oxygen, dust, etc.) when not being dispensed. The volume adjustment device 120 also enables easy volume adjustment in accordance with the control of the opening cover 12, i.e., the control of the area of ​​the container opening 11 that is opened by acting on the opening cover 12.

[0094] Preferably, as in the illustrated embodiment, the sliding assembly 122 includes a plurality of elastic elements 122' connected to the volume adjustment element 121 to position the volume adjustment element 121 in a closed position when the sliding device 120 is not being operated. In this way, the volume adjustment device 120 ensures the protection of the bulk product while simultaneously avoiding overfilling of the product.

[0095] The sliding assembly may, according to further embodiments (not shown), comprise a single elastic element or may not comprise any elastic elements at all.

[0096] Figure 2 also shows a door 113 to which the housing 110 of the bulk volume adjustment unit 100 is located, as described above, and this door closes the housing volume section. In particular, the door 113 allows access to the housing volume section.

[0097] In this invention, the above-mentioned volume adjustment device 120 is provided on the door 113, so that the door allows access not only to the storage volume section but also to the entire volume adjustment device 120. In this respect, the operation of loading and unloading the bulk product container 10 is simplified.

[0098] In particular, the volume adjustment element 121 is preferably provided mostly on the inner surface of the door 113, with one end facing the storage volume section, and only the nozzle portion 121'' (if any) extending from the outer surface of the door 113 and inserted from the inner surface of the door 113.

[0099] In a further embodiment (not shown), the bulk volume adjustment unit may not have any such door at all, and the volume adjustment device may be located, for example, on a frame positioned on the outer surface of the housing.

[0100] The supply assembly 130 is also part of the bulk quantity adjustment unit 100 according to the present invention. This supply assembly 130 is at least partially located inside the housing 110 and can move the bulk product in the bulk product container 10 toward the dispensing opening 112.

[0101] The supply assembly 130 according to the present invention comprises a plate 131, the plate 131 capable of moving bulk product containers 10 that are positioned on or in contact with the plate 131. This movement may include compression of the bulk product containers 10, or may be replaced by such compression, as in this embodiment. The plate 131 is movable within the storage volume section between a stationary position in which the plate 131 is positioned inside the storage volume section to maximize the volume available to the bulk product containers 10 within the storage volume section, and a maximum displacement position in which the plate 131 is positioned inside the storage volume section to minimize the volume available to the bulk product containers 10 within the storage volume section.

[0102] In this regard, Figure 3A shows a perspective view of the bulk volume adjustment unit 100 of Figure 1 with plate 131 in the maximum displacement position (while Figure 3B shows a side plan view of the same bulk volume adjustment unit 100 of Figure 3A). Furthermore, Figure 4A shows a perspective view of the bulk volume adjustment unit 100 of Figure 1 with plate 131 in the stationary position (while Figure 4B shows a side plan view of the same bulk volume adjustment unit 100 of Figure 4A).

[0103] In this embodiment, in the stationary position, the plate 131 is substantially positioned on the side 110' of the housing 110 within the storage volume section, i.e., on the bottom side of the housing volume section. The shape and extent of the plate 131 substantially correspond to the shape and extent of this side 110' of the housing 110, and the plate 131 is separated from the side by a distance that allows the volume adjustment element 121 to move between the closed position and the maximum dispensing position, and in the opposite direction. In the maximum displacement position, the plate 131 is separated from the side 110' of the housing 110 within the storage volume section and is inclined with respect to the side 110'. Thus, the plate 131 defines a rotating support for the bulk product container 10 that rotates around the plate axis 131'. This shaft 131' is located inside the housing 110 at the door of the bulk volume adjustment unit 100, and therefore, the rotation of the plate 131 compresses and tilts a portion of the bulk product container 10, defining an inclination that allows gravity to move the bulk contents toward the container opening 11.

[0104] Plate 131 helps to enable an easy method of discharging the bulk product almost completely from the bulk product container 10 during the dispensing operation, minimizing residue.

[0105] Furthermore, by positioning the plate 131 on the side 110' of the housing 110, it becomes possible to reduce the complexity and installation area of ​​the bulk volume adjustment unit 100.

[0106] In a further embodiment (not shown), at the maximum displacement position, the plate is separated from the side of the housing within the storage volume and parallel to the side. In this way, the plate defines a translational support for the bulk product container from one side to the opposite side.

[0107] In further embodiments (not shown), two or more plates may be part of a supply assembly, or the shape and dimensions of the plates may differ from those of the sides that are positioned in a stationary location. Finally, different elements may be used instead of such plates.

[0108] The supply assembly 130 further comprises a pressing device operably connected to the plate 131 for pressing the plate toward the maximum displacement position.

[0109] The pressing device maintains the bulk product container 10 in a preferred position for dispensing and presses the bulk product toward the container opening 11.

[0110] In a preferred embodiment, the pressing device includes a piston 132' that passively acts as a spring to press the plate 131, and a lever 132'' for limiting the rotation angle of the plate 131.

[0111] In further embodiments not shown, the pressing device can be realized by different elements that ensure the movement or translation of the aforementioned plate within the housing.

[0112] In this embodiment, the supply assembly 130 further comprises a locking device operably connected to the plate 131 and the door 113. The locking device comprises a locking mechanism 133 located inside the housing 110 in a stationary position for locking the plate 131 in a stationary position, and an unlocking mechanism operably connected to the locking mechanism 133 and positioned to at least partially contact the door 113 for unlocking the plate 131 from the stationary position when the door 113 is closed.

[0113] The locking mechanism 133 is defined by a clipping mechanism for fixing the plate 131 to a horizontal position, i.e., to the side surface 110'. This clipping mechanism includes a spring-biased clip 133' that engages with the corresponding locking portion 133'' of the plate 131, enabling the plate 131 to be maintained in a stationary position.

[0114] The unlocking mechanism is defined by a combination of an unlocking shaft 134 operably connected to a spring-biased clip 133' and an unlocking pin 135 operably connected to the unlocking shaft 134. When the door 113 is closed, pressing the unlocking pin 135 activates the rotation of the unlocking shaft 134, which disengages the spring-biased clip 133' from the locking portion 133'', allowing the plate 131 to automatically move from its stationary position to its maximum displacement position.

[0115] In this way, the locking mechanism 133 makes it possible to easily load the bulk product container 10 into the storage volume section, reducing the effort required from the operator responsible for loading. Furthermore, this unlocking mechanism allows the plate 131 to be automatically positioned for dispensing without any intervention from the operator.

[0116] Figure 8 is a perspective view showing a bulk quantity adjustment system 1 in a preferred embodiment of the present invention. The bulk quantity adjustment system 1 comprises a bulk quantity adjustment unit 100 according to a preferred embodiment of the present invention and a bulk product container 10 according to a preferred embodiment of the present invention. In particular, the bulk product container 10 can be housed in a housing 110.

[0117] Therefore, the bulk volume adjustment unit 100 and the bulk product container 10 according to the present invention can cooperate to maximize their effects, with one part, namely the bulk volume adjustment unit 100, referring to the cooperating part, namely the bulk product container 10, and vice versa.

[0118] The following describes a method for dispensing and adjusting the volume of a bulk product using the bulk product container 10, bulk volume adjustment unit 100, and bulk volume adjustment system 1 according to the present invention, and this description is made according to preferred embodiments, which may be subject to modification, i.e., omission of steps.

[0119] The bulk product container 10 is preferably of a flexible type (such as a flexible bag) and can be delivered to stores selling bulk products. The bulk product container 10 preferably comprises a closed enclosure 13 having a container opening 11 covered by an airtight membrane opening 15 and an opening frame 14. The opening cover 12 may be provided on the bulk product container 10 or may be reused from a previously empty bulk product container 10.

[0120] Before use, the retailer (or general user) sets the opening cover 12, which corresponds to the opening frame 14, in the fully closed position according to the sequence in Figures 6 and 7A, and then removes the opening membrane 15 (the opening cover 12 may already be in a predetermined position on the opening frame 14). Thus, the container opening 11 can remain closed by the opening cover 12 alone.

[0121] The bulk volume adjustment unit 100 needs to be prepared for the insertion of the bulk product container 10. In this embodiment, this is followed by the opening of the door 113. Figure 5 shows the bulk volume adjustment unit 100 in a closed configuration. The door 113 is unlocked and opened by rotation, as shown in Figures 3A and 3B, giving access to the plate 131. To insert the bulk product container 10, the plate 131 is pushed down to a stationary position by rotating around the plate axis 131'.

[0122] Since plate 131 is secured in a horizontal position, the bulk volume adjustment unit 100 is ready for insertion of the bulk product container 10. Furthermore, the volume adjustment element 121 is coupled to the sliding assembly 122.

[0123] The bulk product container 10 is inserted into the bulk volume adjustment unit 100. In particular, as shown in Figure 9, the bulk product container 10 is inserted through the opening of the door 113 of the housing 110 and is housed in the storage volume section above the aforementioned plate 131. The depressurized bulk product container 10 facilitates insertion and provides a rigid shape.

[0124] Once inserted, the bulk product container 10 is secured relative to the housing 110 or door 113, as clearly shown in detail in Figure 10.

[0125] In this regard, the housing 110 further includes a locking device 114 for the opening frame 14 of the bulk product container 10, which can firmly maintain the position of the opening 11 of the bulk product container 10 relative to the housing 110 while the volume adjustment device 120 is in operation. This ensures the firm positioning of the bulk product container 10 and the smooth operation of the volume adjustment device 120.

[0126] In this embodiment, the locking device 114 is defined by an upper and a bottom formed to hold and lock the opening frame 14 between the upper and bottom, but different arrangements can also be used. In particular, the locking device 114 has a rotating rocker as the upper part for contacting the bottom and securing the opening frame 14.

[0127] At this point, the opening membrane 15 has been removed in order to activate the bulk product container 10.

[0128] When the bulk product container 10 is inserted, the sliding device 120 is connected to the opening cover 12 by closing the door 113 of the bulk volume adjustment unit 100, allowing the bulk product to be dispensed from the bulk product container 10. In the detailed view of Figure 10, the release pin 135 of the door 113, which acts as the release mechanism for the plate 131, can also be seen. When the door 113 is closed, the spring-biased clip 133'' is released by the rotation of the release shaft 134, which is actuated by pressing the release pin 135. Thus, the plate 131 can begin to move from its stationary position toward its maximum displacement position.

[0129] As shown for the bulk volume adjustment system 1 in Figure 11, the bulk volume adjustment unit 100 is ready for use.

[0130] By pulling the lever (handle) 124 downward, the bulk product container 10 is opened, allowing the bulk product to flow through the container opening 11, which is connected to the opening cover 12 and the container engagement parts 12', 12''. The combination of the volume adjustment device 120 and the opening cover 12 allows for a precise rate of bulk product dispensing by changing the opening surface of the opening cover 12. The sliding assembly 122 is guided by rails fixed to the door 113, and an elastic element 122' ensures that when the lever 124 is released, the opening cover 12 slides back to the fully closed position of the bulk product container 10.

[0131] By emptying the bulk product container 10 through the container opening 11, the plate 131 is pushed upward by the piston 132' (rotating around the plate axis 131'), allowing a constant pouring flow through the container opening 11. Thus, the plate 131 can compact the flexible bulk product container 10, as shown in the side plan view of Figure 12.

[0132] When the plate 131 reaches its maximum angle, all of the bulk product is poured out through the container opening 11 (leaving little or no residue), and the bulk product container 10 is folded to its maximum compression, as shown in the side plan view of Figure 13.

[0133] When the bulk product container 10 is empty, the door 113 opens and the bulk product container 10 is removed.

[0134] Figure 14 is a front perspective view of the bulk quantity adjustment system of Figure 8 when removing an empty bulk product container 10 from the housing 110.

[0135] Figure 15 shows the bulk volume adjustment unit 200 in an open configuration according to a second embodiment of the present invention. In particular, the bulk volume adjustment unit 200 of the second embodiment corresponds to the bulk volume adjustment unit 100 of the first embodiment, as shown in the detailed view of Figure 15, but the locking device 214 of the opening frame 14 is of a different type. In this regard, the same reference numerals are maintained when referring to the same elements.

[0136] Therefore, the housing 110 is equipped with a locking device 214 for the opening frame 14 of the bulk product container 10, which can firmly maintain the position of the opening 11 of the bulk product container 10 relative to the housing 110 while the volume adjustment device 120 is in operation. This ensures the firm positioning of the bulk product container 10 and the smooth operation of the volume adjustment device 120.

[0137] In a second embodiment, the locking device 214 is defined by a locking plate 214' that can rotate around an axis corresponding to the same axis as the dispenser door 113. The locking plate 214' is provided with a locking wall 214'' that is slidable relative to the locking plate 214'. According to another embodiment not shown, a different axis of rotation may be used for the movement of the locking plate, but a different movement of the locking wall may also be provided.

[0138] The rotation of the lock plate 214' and the sliding of the lock wall 214'' allow the bulk product container 10 to be locked and unlocked within the bulk quantity adjustment unit 200, as shown in Figures 17 to 20, thereby defining the bulk quantity adjustment system 2. This ensures that the bulk product container 10 is positioned correctly and prevents the bulk product (such as coffee powder) from accumulating on top of the opening frame 14 of the bulk product container 10. In particular, the lock plate 214' is movable (by rotating relative to its axis) from the container unlocked position (shown in Figure 17) to the container locked position (shown in Figures 15, 19, and 20), and vice versa. Furthermore, the lock wall 214'' is movable (by sliding relative to the lock plate 214') from the frame locked position (shown in Figures 19 and 20) to the frame unlocked position (shown in Figures 16, 17, and 18), and vice versa.

[0139] Therefore, in the container unlocked position, the lock plate 214' allows the bulk product container 10 to be housed in the housing 110 by enabling full access to the bulk product container 10. In the container locked position, the lock plate 214' closes at least partially, preventing the bulk product container 10 from being housed in or removed from the housing 110. In the frame locked position, the lock wall 214'' presses against the frame 14, allowing the frame 14 of the bulk product container 10 to be firmly locked in place (while housed in the housing 110). In the frame unlocked position, the lock wall 214'' is removed from the frame 14, allowing the lock plate 214' to move.

[0140] The lock wall 214'' preferably has dimensions such that its thickness completely covers the thickness of the frame 14, but different thicknesses can also be used.

[0141] Figure 15 shows the lock plate 214' and lock wall 214'' in the container lock position and the frame lock position, respectively.

[0142] Figure 16 is a perspective view showing the bulk quantity adjustment unit 200 of the second embodiment, in a state where the lock plate 214' moves (rotates) from the container lock position to the container unlock position, preparing the bulk quantity adjustment unit 200 for insertion of the bulk product container 10. In the second embodiment, this is followed by the opening of the door 113.

[0143] To insert the bulk product container 10, the plate 131 is pushed down to a stationary position by rotating around the plate axis.

[0144] Since plate 131 is secured in a horizontal position, the bulk volume adjustment unit 200 is ready for insertion of the bulk product container 10. Furthermore, the volume adjustment element 121 is coupled to the sliding assembly 122.

[0145] The bulk product container 10 is inserted into the bulk volume adjustment unit 200. In particular, as shown in Figure 17, the bulk product container 10 is inserted through the opening of the door 113 of the housing 110 and is housed in the storage volume section above the aforementioned plate 131. The depressurized bulk product container 10 facilitates insertion and provides a rigid shape.

[0146] Once inserted, the bulk product container 10 is secured by the locking device 214, which firmly maintains the position of the opening of the bulk product container 10 relative to the housing 110 while the volume adjustment device 120 is in operation. This is achieved by first returning the lock plate 214' from the container unlocked position to the container locked position, as shown in the sequence in Figures 18 and 19. Then, as also shown in Figure 19, the lock wall 214'' is moved from the frame unlocked position to the frame locked position. Preferably, the lock wall 214'' is slid downward relative to the lock plate 214' and moved until it contacts (preferably by pressing) the frame 14.

[0147] As shown in Figure 20, at this point, the opening membrane 15 has been removed in order to operate the bulk product container 10.

[0148] When the bulk product container 10 is inserted, the sliding device 120 is connected to the opening cover 12 by closing the door 113 of the bulk volume adjustment unit 200, allowing the bulk product to be dispensed from the bulk product container 10, as already described in the first embodiment cited herein by reference. The locking device 214 according to the second embodiment thus prevents the bulk product from accumulating on the upper edge of the frame 14 during the dispensing operation, and this effect is achieved even considering the dimensions of the locking wall 214''.

[0149] When the bulk product container 10 is empty, the door 113 is opened again, and the bulk product container 10 is removed by repeating the same operation described above in reverse order to store the bulk product container 10.

[0150] Accordingly, the present invention describes a bulk quantity adjustment unit that is preferably single-use and uses a flexible bulk product container as a canister. The bulk product container is placed inside the bulk quantity adjustment unit and a sliding device allows the container opening to be opened and closed via an opening cover. The bulk product container is placed on a plate and the bulk product container is compressed, allowing the remaining bulk product to be pushed out toward the outlet.

[0151] The object of the present invention is a bulk volume adjustment unit, a bulk product container, and a bulk volume adjustment system, which enable multiple volume adjustments of powdered or solid products from the aforementioned bulk product container via the bulk volume adjustment unit connected thereto, and allow loading and unloading of the bulk product container without the user having to touch the volume-adjusted bulk product.
