An aspect of some embodiments of the invention relates to structural hybrid panels comprising a combination of a resistant lightweight panel with a functional frame to potentially obtain products with improved technical advantages. In some embodiments, the functional frame is made of plastic, optionally recycled plastic. In some embodiments, the lightweight panels comprise a honeycomb internal structure and/or an alveolar internal structure. In some embodiments, the functional frame is incorporated into the resistant lightweight panel by one or more processes, for example overmolding process, joint panels by one or more processes, for example, gluing, welding, snapping, riveting and screwing. In some embodiments, the frame comprises functional structures that are added to the panel by one or more processes, for example injection molding processes, gluing, welding, snapping, riveting and screwing.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

To ease the explanations the following terminology will be constantly used over the description of the invention. The term “hybrid panel” refers hereinafter to the final product achieved by the combination of a panel with a frame. The term “panel” refers hereinafter to the panel that is used where the addition of the frame will be performed by one or more processes, for example injection molding, gluing, welding, snapping, riveting and screwing. The term “frame” refers hereinafter to the parts of the hybrid panel that are added to the mold and optionally comprises one or more functional elements. It should be understood, also in view of the following explanations, that the additional parts are not limited to a frame, as will be seen for example in Figures 6a-c, part 612, where additional parts are added to the panel but are not limited to a frame.

Referring now to Figure 1, showing a schematic representation of a hybrid panel 100, according to some embodiments of the invention. In some embodiments, the hybrid panel comprises a panel 102 on which, by using one or more processes, for example injection over molding processes, gluing processes, welding processes, snapping processes, riveting processes and screwing processes, a frame (additional parts) 104 optionally comprising one or more functional elements (not shown in Figure 1) are added. In some embodiments, the one or more functional elements are added a priori to the frame. In some embodiments, the panel comprises a geometry, and the addition of the parts (frame and/or others) changes the geometry of the panel, as will be further evidenced by the explanations and examples below.

Exemplary panel

Referring now to Figure 2, showing a schematic representation of an exemplary panel 102, according to some embodiments of the invention. In some embodiments, the panel 102 comprises an internal structure (core), optionally comprising an alveolar and/or honeycomb core structure 202 covered by a protective layer 204a-b on both sides. In some embodiments, this is called a sandwich- structure composite. In some embodiments, a sandwich- structured composite is a class of composite materials that is fabricated by attaching two thin but stiff skins to a lightweight but thick core. In some embodiments, the core material is optionally low strength material, but its higher thickness potentially provides the sandwich composite with high bending stiffness with overall low density. In some embodiments, the core materials can be one or more of an open-cell-structured and/or a closed-cell-structured made of one or more of foams, for example polyethersulfone polyvinylchloride, polyurethane, polyethylene or polystyrene foams, or made of balsa wood, syntactic foams, or paper/recycled paper made and/or derived materials, thermoplastic material, resin, reinforced resin or concrete. In some embodiments, the core materials are made of plastic, optionally recycled plastic. In some embodiments, optionally, the honeycomb structure is filled with other foams for added strength. In some embodiments, optionally, open- and closed-cell metal foam are used as core materials. In some embodiments, laminates of glass or carbon fiber-reinforced thermoplastics or thermoset polymers (unsaturated polyesters, epoxies...), resin, reinforced resin, wood or concrete are used as skin materials. In some embodiments, optionally, sheet metal is also used as skin material in some cases. In some embodiments, the skin materials are made of plastic, optionally recycled plastic. In some embodiments, the core is bonded to the skins with an adhesive or with metal components by brazing together.

In some embodiments, the sandwich structure comprises a metal composite material (MCM) formed from two thin skins of metal bonded to a plastic core in a continuous process under controlled pressure, heat, and tension. In some embodiments, the sandwich structure comprises a recycled paper over a closed-cell recycled kraft honeycomb core, therefore providing a lightweight, strong, and fully repulpable composite board. In some embodiments, the core type and the way the core supports the skins, sandwich structures are divided into the following groups: homogeneously supported, locally supported, regionally supported, unidirectionally supported, bidirectionally supported.

In some embodiments, the panel comprises a geometry, for example, a square, a rectangle, a circle, or any other geometrical form. In some embodiments, the geometry is changed by the addition of the frame and/or the additional elements during the injection molding process. In some embodiments, the panel is prepared for the injection process by cutting parts of it, according to the technical needs of the final product.

In some embodiments, the mechanical strength of a hybrid panel is from about 40% to about 50% higher than a panel alone. Optionally from about 30% to about 60% higher than a panel alone. Optionally from about 20% to about 70% higher than a panel alone. In some embodiments, the difference in strength is provided by the overmolded portions. In some embodiments, the difference in strength is provided by the internal structure of the panels used in the hybrid panels.

In some embodiments, the panel can be completely or partially transparent, by using for example panels of transparent polycarbonate, thereby providing a hybrid panel where a user con look inside the final product.

Exemplary connection between panel and frame

Referring now to Figure 3, showing a schematic representation of a cross section of an exemplary hybrid panel, according to some embodiments of the invention. In some embodiments, as mentioned above, the hybrid panel comprises a panel 102, which optionally comprises an alveolar core (or honeycomb core) 202 covered on both sides by a protective layer 204a-b, and a frame 104, which is overmolded on the panel, optionally by a process of injection molding. In some embodiments, the panel comprises an area comprising a reduction in the thickness of the alveolar core 302. In some embodiments, the frame is overmolded on the panel at that area of reduction of the thickness of the alveolar core. In some embodiments, optionally, the thickness of the frame is calculated so it will complement the difference in the thickness of the alveolar core. In some embodiments, a potential advantage of this is that this provides a hybrid panel having the same thickness along the whole surface. In some embodiments, the overmolding of the frame is performed on a panel that do not comprise a reduction in the alveolar core. In some embodiments, there will be a difference in the thickness between the frame and the panel in the hybrid panel (as shown for example in the pallet shown in Figures 6a-6c). In some embodiments, the frame comprising the functional elements is manufactured around the panel. In some embodiments, the frame comprising the functional elements is manufactured inside the area of the panel, as shown for example in Figures 6a-6c, part 612 of pallet 600.

In some embodiments, the frame comprising the functional elements change the geometry of the panel. For example, in some embodiments, the panel is a flat panel having certain dimensions that define a geometry of the panel. In some embodiments, the addition of the frame changes that geometry by adding elements that change those dimensions and/or add one or more dimensions to the dimensions already found in the panel (for example from planar to tridimensional as seen for example in Figures 8a-b).

In some embodiments, the overmolding portions added to the frame comprise a thickness of from about 2mm to about 10mm, optionally from about 1mm to about 20mm, optionally form about 0.5mm to about 50mm. In some embodiments, the overmolding portions provide strengthening characteristics to the panel, for example: an increase in mechanical strength of from about 40% to about 50%. Optionally from about 30% to about 60%. Optionally from about 20% to about 70%.

Exemplary non-overmoulded connection between panel and frame

In some embodiments ,_as mentioned above, the hybrid panel comprises a panel 102, which optionally comprises an alveolar core (or honeycomb core) 202 covered on both sides by a protective layer 204a-b, and a frame 104, which are connected to each other by processes other than overmoulding, for example gluing processes, welding processes, snapping processes, riveting processes and screwing processes.

Exemplary planning of an exemplary frame

In order to facilitate the explanations, an example will be used to hopefully ease the understanding of the invention to a person having skills in the art. It should be understood that the example is just that, an example, and it should not limit the scope of the invention in any way. Referring now to Figure 4 and Figure 5, Figure 4 showing an exemplary product comprising a plurality of hybrid panels, according to some embodiments of the invention, and Figure 5 showing a flowchart of an exemplary method of planning exemplary frames for the exemplary hybrid panels used in the exemplary product shown in Figure 4, according to some embodiments of the invention. Referring now to Figure 4, showing an exemplary product 400 comprising a plurality of hybrid panels, according to some embodiments of the invention. In some embodiments, the product is a pallet with foldable walls 400 used, for example, for transporting goods. In some embodiments, the pallet comprises a base 402 and four foldable walls 404a-d. In some embodiments, one or more of the four foldable walls 404a-d are hybrid panels, where the center of the foldable wall is a panel 102 and the plastic around it is the frame 104, as shown for example on foldable wall 404c in Figure 4. In some embodiments, in order to generate the foldable wall 404c of the pallet with foldable walls 400, a planning process is performed. In some embodiments, the planning process comprises evaluating what are the necessary functional elements required for each hybrid panel.

Referring now to Figure 5, showing a flowchart of an exemplary method of planning exemplary frames for the exemplary hybrid panels, according to some embodiments of the invention. In some embodiments, the method comprises one or more of the following parts. It should be understood that the following method is an exemplary method and it is disclosed to allow a person having skills in the art to understand the invention. It should be understood that the following method should not limit the invention in any form.

Evaluating final product

In some embodiments, the planning process commences by evaluating the locations and roles of the hybrid panels in a final product 502. For example, the foldable walls of the pallet with foldable walls 400 are located on top of the base 402 and their role is dual, when open, they provide protection to what is stored on the pallet, and when closed, they allow easy transport of the pallet without taking too much space.

Assessing required functional elements

In some embodiments, each hybrid panel is assessed for the required functional elements 504. For example, the foldable walls of the pallet with foldable walls 400 are interconnected to the base, for example, by built-in hinges located half on the frame and half on the base (they interconnect by clicking them together). Another example, for foldable wall 404b, on the internal side of the side of the frame, there are indentations for the insertion of protrusions from the adjacent foldable walls for the correct interconnection and holding of said adjacent foldable walls. Manufacturing an hybrid panel

In some embodiments, the next step is to connect a panel with a frame by one or more of the following processes: overmoulding process, gluing processes, welding processes, snapping processes, riveting processes and screwing processes, optionally the frame comprising all functional elements, thereby manufacturing a hybrid panel 506.

Assembling the final product

In some embodiments, once all the parts are manufactured, they just need to be assembled together to provide the final product 508.

Exemplary short process of manufacture of a hybrid panel

In some embodiments, the short process comprises procuring a panel and adding a frame on at least parts of the panels. In some embodiments, the adding a frame provides functional structures to the panel. For example, strengthening frames, interconnection means (like hinges or protrusions or indentations), legs, walls, etc.

In some embodiments, on the internal side of two or more foldable walls, generated by the addition of functional features on the frame of those hybrid panels, there are indentations that generate one or more protrusions 724 on the foldable wall (on the frame of the hybrid panel). In some embodiments, one or more dividers 726 can be used in a single box 700. In some embodiments, the dividers themselves are also hybrid panels manufactured with functional features to perform as a divider and be held by the protrusions 724.

In some embodiments, the box comprises an optional cover (not shown), for covering the box 700, once it is loaded.

In some embodiments, when the foldable box 700 is fully folded, it can potentially become as thin as a regular pallet. In some embodiments, a potential advantage of this is that when needed to be returned, the boxes are folded and they take less space.

In some embodiments, the foldable container is characterized by a mechanical strength of from about 40% to about 50% higher than similar regular containers. In some embodiments, the mechanical strength is increased by the hybrid panels used in the foldable container.

In some embodiments, the foldable container is characterized by walls having a thickness from about 5% to about 20% thinner than similar regular containers. In some embodiments, the hybrid panels used for the foldable container allow the use of thinner walls without compromising the overall strength of the foldable container.

In some embodiments, the foldable container is characterized by having an internal storage space of from about 5% to about 10% higher than similar regular containers. In some embodiments, the fact that the hybrid panels are thinner than regular panels used for similar products, it allows to increase the internal storage space without increasing the overall dimensions of the foldable container. In some embodiments, the internal space storage comprises a base of from about 700x1000mm to about 800x1300mm, for example 770x1170mm.

In some embodiments, the ratio between the height of a folded foldable container and the height of an unfolded foldable container is from about 1:3 to about 1:4.

Exemplary method of manufacturing a pallet with foldable walls (box)

Referring now to Figure 7j, showing a flowchart of an exemplary method of manufacturing a pallet with foldable walls made of a plurality of hybrid panels, according to some embodiments of the invention.

In some embodiments, the planning process commences by evaluating the locations and roles of the plurality of hybrid panels in the box 730. For example, for the exemplary box 700 there are needed ten different hybrid panels: two full foldable walls, two foldable walls with windows, two windows, a cover (not shown) and three dividers (2+2+2+1+3=10). In this example, the base is made of a one piece of molded plastic.

In some embodiments, each hybrid panel is assessed for the required functional elements 732. For example, the foldable walls are interconnected to the base, for example, by built-in hinges located half on the frame and half on the base (they interconnect by clicking them together). Another example, on the internal side of the side of the frame, there are indentations for the insertion of protrusions from the adjacent foldable walls for the correct interconnection and holding of said adjacent foldable walls. Another examples, as disclosed above, the locking mechanisms, the dividers, etc.

In some embodiments, the next step is to connect a panel, comprising the necessary size, with a frame, the frame optionally comprises all functional elements, thereby manufacturing a hybrid panel 734.

In some embodiments, once all the parts are manufactured, they just need to be assembled together to provide the final product 736.
