DETAILED DESCRIPTION

[0076] In the following description, various aspects of the disclosure will be described. For the purpose of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the different aspects of the disclosure. However, it will also be apparent to one skilled in the art that the disclosure may be practiced without specific details being presented herein. Furthermore, well-known features may be omitted or simplified in order not to obscure the disclosure.

[0077] According to some embodiments, there are provided herein a method and a system for flow packing produce with an aerated packaging material prior to sealing thereof for handling and delivery.

[0078] The term produce is defined herein as any agricultural product, preferably a plant or fungus based agricultural product, such as an herb, seed, root, stem, fruit or vegetable. Optionally, the produce may be a fruit body, root, tuber, seed, stem, leaf, or flower. Optionally, any type of produce may be used, such as, but not limited to: cherry tomato, fig, apricot, green bean, pea, nectarine, peach, pomegranate, cherry, grape, pear, apple, plum, orange, grapefruit, mandarin, lemon, pepper, carrot, cucumber, coconut, artichoke, pumpkin, onion, garlic, broccoli, cauliflower, nut, bean, mango, zucchini, eggplant, fennel, radish, mushroom, lettuce, kale, celery, parsley, coriander, etc. Optionally, a mixture of different types of produce may be packaged together, e.g., ingredients for a soup, salad, juice, etc.

[0079] According to some embodiments, the scaffold may include any structure that is configured to support the aerated packaging material and accommodate the produce therein. The scaffold may have a frame structure or may be shaped like a box and/or like a boat. Optionally, the scaffold may comprise plastic, cardboard, wood, metal, silicone, any other appropriate material, and/or any combination thereof. Each option is a separate embodiment. Preferably, the scaffold may be rigid enough to support the aerated packaging material and/or the produce.

[0080] According to some embodiments, the scaffold may include an upper edge and a produce outlet opening. Optionally, the upper edge may be configured to hold open an aerated packaging material. Optionally, the scaffold may have one or more configurations. Optionally, the scaffold may have at least two configurations. Optionally, in a first configuration of the scaffold, produce confined within the aerated packaging material may be prevented from exiting through the produce outlet opening. Optionally, in a second configuration of the scaffold, exit of produce enclosed within the aerated packaging material through the produce outlet opening may be facilitated.

[0081] According to some embodiments, the scaffold may have at least one rail. Optionally, the rail may protrude from, indent within or be attached to an outer surface of the scaffold. Optionally, the scaffold may include two rails mounted on the outer surfaces of two parallel sides of the scaffold. Optionally, the rail may be a lip and/or rim on an outer surface of the scaffold. Optionally, the rail may comprise plastic, cardboard, wood, metal, silicone, any other appropriate material, and/or any combination thereof. Each option is a separate embodiment. Optionally, the one or more rails may be configured to be used to lift the scaffold. Optionally, the one or more rails may be configured to be used to support the scaffold. Optionally, the scaffold may be rigid.

[0082] According to some embodiments, the scaffold may be placed on a surface (e.g., a work surface, conveyer belt, etc.). Optionally, the surface may block one or more produce outlet openings of the scaffold. Optionally, the scaffold may be separated from the surface by lifting the scaffold, changing the inclination of the scaffold, removing the surface from under the scaffold, etc. Each possibility is a separate embodiment.

[0083] According to some embodiments, the produce outlet opening may be located on the bottom of the scaffold opposite the upper edge. Optionally, the produce outlet opening may be blocked when the scaffold is placed on a surface. Optionally, upon separating the scaffold from the surface, the produce outlet opening may be unblocked, thereby allowing the weight of the produce within the aerated packaging material to push the enclosed produce out through the produce outlet opening. Optionally, the separating between the scaffold and the surface may be performed by lifting the scaffold and/or supporting the scaffold while removing the surface on which the scaffold may be positioned. Optionally, the scaffold may be lifted and/or supported utilizing at least one rail of the scaffold.

[0084] According to some embodiments, the produce outlet opening may be located on a side of the scaffold at an angle to and/or essentially perpendicular to the upper edge. Optionally, the produce within the aerated packaging material may be maintained within the scaffold when the scaffold is placed horizontally on the surface. Optionally, upon changing the inclination of the scaffold, the weight of the produce within the aerated packaging material may push the enclosed produce out from the produce outlet opening. Optionally, upon changing the angle of the scaffold with respect to the horizontal surface, the weight of the produce within the aerated packaging material may push the enclosed produce out from the produce outlet opening. For example, tipping the scaffold and/or lifting the scaffold at an angle to allow the weight of the produce within the aerated packaging material to push the enclosed produce out from a produce outlet opening (e.g., located on a side of the scaffold).

[0085] According to some embodiments, the scaffold may be reusable.

[0086] According to some embodiments, the aerated packaging material may be configured for closing by an elastic band. According to some embodiments, the aerated packaging material may comprise an elastic material. According to some embodiments, the aerated packaging material may be configured to maintain a group of produce together in a bundle, e.g., net, pouch, bag, etc.

[0087] According to some embodiments, the aerated packaging material may comprise of a synthetic and/or natural material. According to some aspects of the present disclosure, the aerated packing material, for example a net, bag, or pouch may be composed of a polymer, such as polypropylene, woven natural material, fibers (for example, flax, hemp, straw, cotton, paper, silk, wool, etc.), any appropriate material, and/or combinations thereof. Each possibility is a separate embodiment.

[0088] According to some embodiments, the aerated packaging material may possess a single opening with an elastic material, e.g., elastic band, tie, etc., which may enable the aerated packaging material to close.

[0089] According to some embodiments, the placement of the aerated packaging material in the scaffold may be performed manually prior to and/or during placement of the scaffold on the conveyor belt. Optionally, the produce may be placed in the aerated packaging material without use of a scaffold. Optionally, produce enclosed by the aerated packaging material may be placed directly onto a conveyer belt for further packaging. Optionally, an elastic band at the opening of the aerated packaging material may be placed over the upper edges of the scaffold. Optionally, the elastic opening of the elastic aerated packaging material may be placed over the upper edges of the scaffold.

[0090] According to some embodiments, the scaffold and aerated packaging material may be used in packing processes as follows: a first step may include a scaffold bearing an aerated packaging material placed manually and/or automatically on the packing line. In a second step, produce (for example cherries, but may be any type of produce, such as, but not limited to, cherry tomatoes, apricots, green beans, peas, nectarines, peaches, pomegranates, cherries, apples, plums, oranges, mandarins, lemons, peppers, carrots, cucumbers, nuts, etc.) may be deposited inside the aerated packing material. In the third step, the scaffold bearing the aerated packaging material and produce may proceed along a conveyer belt as a single unit to the flow pack machine. The scaffold bearing the aerated packaging material and produce may then be lifted (for example, automatically lifted by grasping and lifting the scaffold using one or more rails or protrusions on one or more sides of the scaffold). The action of lifting the scaffold may cause the aerated packaging material bearing the bundled produce to drop through the opening of the scaffold (for example through the produce outlet opening), and optionally simultaneously, the weight of the produce may cause the aerated packaging material to be released from the upper edges of the scaffold, which may result in contraction of the opening (the mouth) of the aerated packaging material (for example, by contraction of an elastic band or the elastic material of the aerated packaging material), which may then enclose the produce. The resulting produce enclosed by the aerated packaging material may then be sealed by packaging in the flow pack machine, resulting in a package which may be appropriate for distribution. The empty scaffold may be reused by returning it to the beginning of the flow process following produce packing.

[0091] In addition to the exemplary aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the figures and by study of the following detailed descriptions.

[0092] Reference is now made to the figures.

Optionally, the aerated packaging material may be a woven, knit, and/or knotted material of open texture with evenly spaced holes. Optionally, the aerated packaging material may comprise various mesh sizes (FIG. 2a-b v. FIG. 2c-d). Optionally, the mesh may be selected according to the size of the produce. Optionally, the mesh size may be selected from mesh with a pores size in the range between about 20 m to about 100 m, in the range between about 100 m to about 1,000 m, in the range between about 1,000 m to about 0.1 mm, in the range between about 0.1 mm to about 1 mm, in the range between about 1 mm to about 10 mm, in the range between about 10 mm to about 25 mm, in the range between about 25 mm to about 50 mm, or in the range between about 50 mm to about 100 mm. Each possibility is a separate embodiment.

[0095] For example, the aerated packaging material 202 may be placed over an upper edge and/or lip of a scaffold 206. Optionally, the scaffold 206 may include a rail 208, which may be located below the upper edge and/or lip of a scaffold 206 over which the aerated packaging material 202 may fit.

[0096] FIG. 3a schematically shows a produce packaging system 300 including a scaffold, according to some embodiments. Optionally, the scaffold 310 may include a rail 306, which may be located below the upper edge 316 and/or lip of a scaffold 310 over which the aerated packaging material 302 may fit.

Optionally, the produce outlet opening may be a symmetrical trap door on the bottom of the scaffold. Optionally, the produce outlet opening may include a hinge, fold, flap, etc. 312 attached to one or more edges of the scaffold. Optionally, a hinge, fold, flap, etc. 312 may be absent. Optionally, the produce outlet opening may have at least two configurations: closed and open. Optionally, in the closed configuration, the produce outlet opening may be closed, locked, or held closed by placing it on a surface e.g., a conveyer belt 308. Optionally, the scaffold may be lifted by a frame 314 connected to the conveyer belt 308.

[0097] FIG. 3b schematically shows a scaffold 310 with an aerated packaging material containing produce, where the scaffold 310 has a symmetrical and/or asymmetrical produce outlet opening 318 e.g., at the bottom, which may be open, according to some embodiments. Optionally, the produce outlet opening 318 may have at least two configurations: closed and open. Optionally, the produce outlet opening 318 may be opened and/or closed and/or locked open or closed. Optionally, the produce outlet opening 318 may be a symmetrical trap door on the bottom of the scaffold which may be in an open configuration. Optionally, the produce outlet opening 318 may include a hinge, fold, flap, etc. 312 attached to one or more edges of the scaffold. Optionally, the produce outlet opening 318 may comprise a flexible, semi-flexible or rigid material. Optionally, the produce outlet opening 318 may comprise a different material or a different weight of material to the rest of the scaffold. Advantageously, the produce outlet opening 318 may be configured to assist in the gentle placement of the produce 304 onto the conveyer belt 308 to reduce and/or prevent damage to the produce, e.g., bruising, breaking, splitting, etc.

[0098] For example, a scaffold 310 bearing a aerated packaging material 302 containing produce 304 may be lifted (for example, automatically lifted by grasping and lifting 314 the scaffold 310 using one or more rails 306, indents or protrusions on one or more sides of the scaffold). The action of lifting the scaffold 310 may cause the aerated packaging material 302 bearing the contained produce 304 to drop through the produce outlet opening 318 at the bottom of the scaffold onto a conveyer belt 308. Optionally, the weight of the produce 304 may cause the aerated packaging material 302 to be released from the upper edges 316 of the scaffold 310, resulting in contraction of the opening (the mouth) of the aerated packaging material (for example, by contraction of an elastic band and/or the aerated packing material), which may then enclose the produce 304.

[0099] FIG. 3c schematically shows various views of scaffold/s 320 for flow packaging produce, where each scaffold has a produce outlet opening which may include one or more doors 324 which may or may not be hinged, foldable, flaps, etc. e.g., a symmetrical trap door at the bottom, according to some embodiments.

Optionally, the scaffolds may be stackable 326. Optionally, the stacked scaffolds may be easily stored and/or transported. Optionally, the scaffold/s may be configured for use for transporting produce through a flow packing process, optionally with modified atmosphere properties.

[0100] FIG. 4a-f schematically show produce packaging system 400 including a scaffold 412 with an aerated packaging material 404 containing produce 406, where the scaffold 412 has a produce outlet opening 418 at the bottom, according to some embodiments. Optionally, the produce outlet opening 418 may have at least two configurations: which may be closed (as in FIG. 4a, FIG. 4c, and FIG. 4e), may be open (as in FIG. 4b and FIG. 4d or partially open as in FIG. 4f) Optionally, the produce outlet opening 418 may be held closed by placing the scaffold 412 onto a surface 410, e.g., a conveyer belt. Optionally, the base of the scaffold 412 may be connected to the base on the front edge of the scaffold by a hinge 414, glue, molding, etc. Optionally, the base of the scaffold may extend directly from the front wall of the scaffold, e.g., as one piece. Optionally, the base of the scaffold 412 may include a flap 418 or may be absent. Optionally, the base of the scaffold 412 may be removable. Optionally, the base and/or the flap 418 may include a flexible, semi-flexible and/or rigid material. Optionally, the base of the scaffold 412 may comprise a different material and/or a different weight of material to the rest of the scaffold 412. Optionally, the base and/or the flap 418 may be configured to assist in the gentle placement of the produce on to the conveyer belt 410 to reduce and/or prevent damage to the produce, e.g., bruising, breaking, splitting, etc.

[0101] For example, a scaffold 412 bearing an aerated packaging material 404 containing produce 406 may be lifted (for example, automatically lifted 416 by grasping and lifting the scaffold using one or more rails 408, indents or protrusions on one or more sides of the scaffold, which may be located below the upper edge 402 of the scaffold 412). The action of lifting the scaffold 412 may cause the aerated packaging material 404 bearing the contained produce 406 to drop gently through the produce outlet opening 418 at the front at the bottom of the scaffold 412 onto a conveyer belt 410. Optionally, the weight of the produce 406 may cause the aerated packaging material 404 to be released from the upper edges 402 of the scaffold, resulting in contraction of the opening (the mouth) of the aerated packaging material 404 (for example, by contraction of an elastic band and/or the aerated packing material), which may then enclose the produce 406.

[0102] FIG. 5a and FIG. 5b schematically show perspective views of produce packaging system 500 including a scaffold 506 with an aerated packaging material 510 containing produce 512 on a (flow) packaging conveyer belt 508, where the scaffold 506 has a produce outlet opening at the back wall (shown in a closed and an open configuration, respectively), according to some embodiments. Optionally, the produce outlet opening at the back wall of the scaffold 506 may be hinged, be a flap and/or the back wall may be absent.

[0103] For example, the scaffold 506 bearing the aerated packaging material 510 containing produce 512 may be lifted (for example, automatically lifted 514 by grasping and lifting the scaffold using one or more rails 504, indents or protrusions on one or more sides of the scaffold). The action of lifting the scaffold 506 may cause the aerated packaging material bearing the contained produce to drop gently through the produce outlet opening at the back of the scaffold 506 onto a conveyer belt 508. Optionally, the weight of the produce 512 may cause the aerated packaging material 510 to be released from the upper edges 502 of the scaffold 506, resulting in contraction of the opening (the mouth) of the aerated packaging material 510 (for example, by contraction of an elastic band and/or the aerated packing material), which may then enclose the produce 512.

[0104] FIG. 6a-c schematically show perspective views of a produce packaging system 600 including a scaffold 604 with an aerated packaging material 602 containing produce 612 used on a conveyer belt 608, where the scaffold 604 has a produce outlet opening at the back with a support member 610 at the bottom, according to some embodiments.

Optionally, the support member 610 may extend directly from the base of the scaffold, e.g., as one piece. Optionally, the support member 610 may be removable. Optionally, the support member 610 may be configured to assist in the gentle placement of the produce 612 onto the conveyer belt 608 to reduce and/or prevent damage to the produce, e.g., bruising, breaking, splitting, etc.

[0105] For example, a scaffold 604 bearing an aerated packaging material 602 containing produce may be lifted (for example, automatically lifted 614 by grasping and lifting the scaffold using one or more rails 606, indents or protrusions on one or more sides of the scaffold). The action of lifting the scaffold 604 may cause the aerated packaging material 602 bearing the contained produce 612 to slide over the support member 610 and out through the produce outlet opening at the rear of the scaffold 604 onto a conveyer belt 608. Optionally, the weight of the produce 612 may cause the aerated packaging material 602 to be released from the upper edges of the scaffold 604, resulting in contraction of the opening (the mouth) of the aerated packaging material 602 (for example, by contraction of an elastic band and/or the aerated packing material), which may then enclose the produce 612.

[0106] FIG. 7 shows a schematic illustration of a produce packaging system 700 including the aerated packing material 702, filled with produce 704, upon removal of the scaffold, according to some embodiments. By removal of the scaffold, the elastic opening of the aerated packaging material 702 may be released, enclosing the produce 704 within the aerated packaging material which may be in preparation for sealing by flow packing.

[0107] FIG. 8 shows a schematic illustration of a produce packaging system 800 including the final packaged product, wherein the aerated packaging material 804 containing the produce 806 (e.g., in the configuration of FIG. 7) may be sealed in a polymer packaging 802 following flow packing, according to some embodiments. Optionally, the flow packing may take place under a modified atmosphere. Optionally, upon sealing, the final package may be ready for distribution.

[0108] For example, the aerated packaging material as shown in FIG. 1 may include an elastic band that can be pulled over and around the upper edge of a scaffold, for example of a box. Produce (for example, cherries, or any type of produce) are placed inside the aerated packaging material, which in turn may be configured to freely close upon release from the upper edge of the scaffolding via the produce outlet opening. This action may contain the produce inside the subsequently closed aerated packing material, as shown in FIG. 7. The released aerated packing material-enclosed produce may then be ready to be conveyed to flow packing, whereupon sealing with a polymer packaging, as shown in FIG. 8, results in the final package which may be suitable for distribution.

[0109] FIG. 9a-c schematically show perspective views of a produce packaging system 900 including a process for using a scaffold with an aerated packaging material containing produce, where the scaffold may have a produce outlet opening e.g., at the rear and/or front and/or at the bottom, according to some embodiments. For example, a scaffold 910 bearing an aerated packing material 902 containing produce 916 may be lifted (for example, automatically lifted 908 by grasping and lifting the scaffold using one or more rails 904, indent or protrusions on one or more sides of the scaffold). The action of lifting the scaffold 910 may cause the aerated packing material 902 bearing the contained produce 916 to push open the base 912 of the scaffold, and to gently deposit the aerated packing material 902 bearing the contained produce 916 through the produce outlet opening onto a conveyer belt 906. Optionally, the weight of the produce 916 may cause the aerated packing material 902 to be released from the upper edges 914 of the scaffold 910, resulting in contraction of the opening (the mouth) of the aerated packing material (for example, by contraction of an elastic band and/or the aerated packing material), which may then enclose the produce 916. The aerated packaging material containing produce 916 deposited on conveyer belt 906 may continue for further packaging and/or which may be placed in an outer carton and palletized for distribution, while the scaffold may continue on the rails, optionally for reuse.

[0110] Reference is now made to FIG. 10, which schematically shows the workflow process 1000 of packaging produce, according to some embodiments. For example, the first step 1004 (similar to that shown in FIG. 4) shows the beginning of the process, wherein aerated packaging material is placed over scaffolds 1006. The scaffolds may include a produce outlet opening having e.g., a trap door (e.g., similar to the scaffolds shown in FIG. 3a-c, 4a-f, 5a-b and/or 6a-c) and may be placed 1008 manually and/or automatically on a conveyer belt 1002. In the second step, produce 1010 (in this case cherries) may be deposited into the aerated packaging material inside the scaffold 1012. In the third step 1014, the scaffolds bearing the aerated packaging material and produce may proceed on the conveyer belt as single units to the flow pack machine 1020, whereupon the scaffolds may be lifted. The action of lifting the scaffolds may cause the aerated packaging material enclosed produce to be dropped through the produce outlet opening 1016 and, optionally simultaneously, the aerated packaging material may be released from the scaffolds' upper edges, which may cause the mouth of the aerated packaging material to contract and enclose the produce 1018. The constrained produce may be enclosed by the aerated packaging material, may then be sealed by further packaging in the flow pack machine, resulting in a final package 1022 which may be placed in an outer carton and palletized for distribution. Optionally, the empty scaffolds may be reused by returning them to the starting point 1024, e.g., either manually, and/or by continuing along the conveyer belt, e.g., using an overhead conveyer belt.

[0111] According to some embodiments, the flow packaging process may include modified atmosphere properties (MAP), which may increase the shelf life of the produce. FIG. 11 is a flow chart of a workflow of produce packaging, according to some embodiments. For example, the packaging process may include obtaining 1102 a scaffold including an upper edge and a produce outlet opening, and an aerated packing material, positioning 1104 the scaffold on a surface, placing 1106 the aerated packaging material over the upper edge of the scaffold, introducing 1108 produce through the upper edge and into the aerated packaging material to confine the produce within the aerated packaging material, separating 1110 the scaffold from the surface and/or changing an inclination of the scaffold, wherein the weight of the produce within the aerated packaging material pushes 1112 the produce out from the produce outlet opening, thereby releasing 1114 the aerated packaging material confining the produce therein from the upper edge of the scaffold and enclosing the produce. The produce enclosed in the aerated packaging material may be further packaged 1116 in a flow pack process, optionally with modified atmosphere properties, resulting in a final package, which may be placed in an outer carton and palletized for distribution. Optionally, flow pack process with modified atmosphere properties may extend the shelf-life of the produce. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention pertains.

[0112] The term a and an refers to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, an element means one element or more than one element.

[0113] The term about when referring to a measurable value such as an amount, a temporal duration, and the like, is meant to encompass variations of 20% or in some instances 10%, or in some instances 5%, or in some instances 1%, or in some instances 0.1% from the specified value, as such variations are appropriate to perform the disclosed methods. Each possibility is a separate embodiment. The following examples are presented in order to more fully illustrate some embodiments of the invention.
