Description

REINFORCED CARDBOARD BOX TECHNICAL FIELD [0001]The present disclosure generally relates to cardboard boxes, and more specifically to reinforced cardboard boxes, which are folded such that a majority of the surface of the box includes double layers.

BACKGROUND [0002]Cardboard boxes are typically used to carry goods from one site to another. For example, in case the goods are fruit, the boxes may be used to carry the fruit from the packaging site to the supermarket or other stores where the fruit are to be sold. There are many types of boxes made of cardboard in the market, and their characteristics change according to the weight they are supposed to carry, the type of goods, the length of the journey that the goods go through until reaching their destination, and so on. One of the major difficulties in using cardboard boxes is the need to ensure stability and completeness of the boxes throughout their journey, since cardboard, though stiff, is also somewhat flexible, and cardboard boxes might undergo a change in shape during the long journey until reaching the end user of the goods carried by the boxes.

SUMMARY [0003]The present disclosure provides a reinforced cardboard box to ensure the box stays intact during usage.According to some embodiments, a reinforced cardboard box may include at least one first corner formed by folding three parallel flaps extending from a front wall of the box, each of the three flaps form a first, a second, and a third face of a first triangle shaped corner. In some embodiments, the three flaps are separated from one another by folding lines, about which the three flaps are folded inwardly towards the front wall of the box. In some embodiments, the reinforced cardboard box may further include a double layered front side formed by folding a first flap extending from the front wall of the box onto an internal side of the front wall, whereby the first flap extends from the front wall in a direction perpendicular to the direction at which the three flaps extend from the front wall. The reinforced cardboard box may further include a double layered back side formed by folding a first flap extending from a back wall of the box onto an internal side of the back wall. In some embodiments, the at least one first corner may include a support per each face of the first triangle shaped corner, such to create a double layer at each face of the first corner, whereby the first face of the first corner may be supported by the front wall onto which the first face is folded, the second face of the first corner may be supported by folding a second flap extending from the first flap of the front wall onto the second face, and the third face of the first corner may be supported by folding a side wall onto the third face. [0004]According to some embodiments, the reinforced cardboard box may further include at least one second corner formed by folding three parallel flaps extending from a back wall of the box, each of the three flaps form a first, a second, and a third face of a second triangle shaped corner. In some embodiments, the three flaps are separated from one another by folding lines, about which the three flaps are folded inwardly towards the back wall of the box. In some embodiments, the at least one second corner may include a support per each face of the second triangle shaped corner, such to create a double layer at each face of the second corner, whereby the first face of the second corner my be supported by the back wall onto which the first face is folded, the second face of the second corner may be supported by folding a second flap extending from the first flap of the back wall onto the second face, and the third face of the second corner may be supported by folding a side wall onto the third face. [0005]According to some embodiments, the reinforced cardboard box may include four double layered triangle shaped corners. [0006]In some embodiments, the reinforced cardboard box may further include holes for ventilating the contents of the box. In some embodiments, the holes are located at the bottom side of the box and/or at the front and back sides of the box. [0007]The present disclosure provides a method for creating a reinforced cardboard box including: folding three parallel flaps extending from a front wall of the box inwardly towards the front wall of the box, whereby each of the three flaps form a first, a second, and a third face of a triangle shaped corner, whereby the three flaps are separated from one another by folding lines, about which the three flaps are folded;folding a first flap extending from the front wall of the box onto an internal side of the front wall, whereby the first flap may extend from the front wall in a direction perpendicular to the direction at which the three flaps extend from the front wall, thereby creating a double layered front side for reinforcing the front side; folding a first flap extending from a back wall of the box onto an internal side of the back wall, thereby creating a double layered back side for reinforcing the back side; reinforcing the triangle shaped corner by folding supports per each face of the triangle shaped corner, such to create a double layer at each face of the triangle shaped corner, whereby the first face of the corner may be supported by the front wall onto which the first face is folded, the second face of the corner may be supported by folding a second flap extending from the first flap of the front wall onto the second face, and the third face of the corner may be supported by folding a side wall onto the third face. [0008]In some embodiments, the method may further include folding three parallel flaps extending from a back wall of the box inwardly towards the back wall of the box, each of the three flaps form a first, a second, and a third face of a second triangle shaped corner, whereby the three flaps may be separated from one another by folding lines, about which the three flaps are folded. [0009]In some embodiments, the method may further include reinforcing the second triangle shaped corner by folding supports to each face of the second triangle shaped corner, whereby the first face of the second corner may be supported by the back wall onto which the first face is folded, the second face of the second corner may be supported by folding a second flap extending from the first flap of the back wall onto the second face, and the third face of the second corner may be supported by folding a side wall onto the third face. [0010]In some embodiments, the method may further include gluing the three parallel flaps to the internal side of the front wall via the first face of the corner. [0011]In some embodiments, the method may further include gluing the first flap extending from the front wall onto the internal side of the front wall. [0012]In some embodiments, the method may further include gluing the side wall onto the third face of the corner.

[0022]With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of embodiments of the disclosure. In this regard, the description taken with the drawings makes apparent to those skilled in the art how embodiments of the disclosure may be practiced. [0023]Identical or duplicate or equivalent or similar structures, elements, or parts that appear in one or more drawings are generally labeled with the same reference numeral, optionally with an additional letter or letters to distinguish between similar entities or variants of entities, and may not be repeatedly labeled and/or described. References to previously presented elements are implied without necessarily further citing the drawing or description in which they appear. [0024]Dimensions of components and features shown in the figures are chosen for convenience or clarity of presentation and are not necessarily shown to scale or true perspective. For convenience or clarity, some elements or structures are not shown or shown only partially and/or with different perspective or from different point of views. [0025]Some embodiments of the present disclosure provide a reinforced cardboard box that ensures safe transfer of any goods that the cardboard box is to carry. As mentioned above, cardboard boxes may come in different shapes and sizes in accordance with the type and weight of the goods that they are supposed to carry, the length of the journey that they are required to pass, and so on. The main problem with cardboard boxed is that although cardboard may be a stiff material, especially when it is not designed to be too thin, cardboard boxes are still subject to deformations, which may cause harm to the good carried by the boxes. [0026]Some manufacturers offer the solution of adding a plastic cover over each of the corners of a box in order to reinforce the corners of the box. However, this solution requires an additional step besides the mere folding of the cardboard box, as well as using another material besides cardboard, which makes the recycling process, if at all possible, much more cumbersome. [0027]Therefore, the system and method provided according to embodiments of the present disclosure enable cardboard boxes to stay intact during their entire usage period, without using any other material besides the cardboard itself. That is, the cardboard boxes are reinforced via the cardboard box itself, and the unique layout of the cardboard box. In addition, since the cardboard boxes of the present disclosure include cardboard only, without the addition of other materials in order to reinforce the cardboard boxes, the boxes of the present disclosure enable full recycling. The cardboard boxed provided in the present disclosure include double-layered front and back sides in order to strengthen these sides of eh boxes, as well as double layered triangle shaped corners in order to strengthen the corners of the boxes. That is, the present disclosure provides triangle shaped corners designed as one triangle shaped corner wrapped by another triangle shaped corner, e.g., a corner designed as a triangle within another triangle, thereby creating a double-layered triangle shaped corner. The corners of a cardboard box are one of the areas of the box that are most subject to deformation due to handling, moving, and transferring of the box. Therefore, the cardboard boxes of the present disclosure provide reinforcement to the corners of the boxes while using a unique layout and folding of the cardboard boxes, without any addition of materials other than the cardboard itself, which saves money, time and enables easy recycling. [0028]In addition, by providing reinforced corners, e.g., double layered triangle shaped corners, or ‘triangle inside triangle’ type corners, a manufacturer of such cardboard boxes may use cardboard of a lower weight in order to produce such a reinforced box, compared to boxes created from cardboard of higher weight, which do not comprise such reinforced corners. That is, the present disclosure provides reinforced cardboard boxes that may be manufactured while saving costs compared to manufacture of boxes, which are made of cardboard of higher weight, and no reinforcement, since lower weight of cardboard is cheaper than higher weight cardboard. id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29" id="p-29"

[0029]Before explaining at least one embodiment of the disclosure in detail, it is to be understood that the disclosure 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 disclosure is capable of other embodiments or of being practiced or carried out in various ways. [0030]Reference is now made to FIG. 1, which is a schematic illustration of an upper perspective view of a spread out cardboard box, according to an embodiment of the disclosure. According to some embodiments, cardboard box 100 may be manufactured in a spread out or laid open configuration, which includes the various sides and flaps of cardboard box 100 before they are folded according to a specific folding scheme. [0031]According to some embodiments, cardboard box 100 may comprise section 110, which may become the bottom side of cardboard box 100, once cardboard box 100 is folded. In some embodiments, bottom side 110 may comprise holes, such as holes 140 and 142. According to some embodiments, holes, such as holes 142 may provide ventilation and air circulation between each cardboard box to another, specifically when the cardboard boxes are stacked one over the other. In some embodiments, holes 140 in a first cardboard box 1may be configured to receive a portion of second flaps 132A-D (detailed herein below) of another cardboard box 100 that is stacked onto the first cardboard box. That is, holes 1enable stable stacking of cardboard boxes 100 one on top of the other. In some embodiments, cardboard box 100 may comprise a front wall 102, which may have attached a first flap 112. In some embodiments, between front wall 102 and first flap 112 that extends from front wall 102, may be folding lines 152, which may dictate the location of the folding of first flap 1over front wall 102, towards what would be the inner side of front wall 102, once cardboard box 100 is in a folded state. Between front wall 102 and first flap 112 extending from front wall 102, may be holes 144A and 144B, which may enable ventilation and some air circulation between cardboard boxes, such as cardboard box 100, when the boxes are stacked one over the other. [0032]In some embodiments, front wall 102 may further comprise three flaps 120A extending from a first end (e.g., the right end) of front wall 102. In some embodiments, front wall 202 may further comprise three flaps 120B extending from a second end (e.g., the left end), typically opposite the first end, of front wall 102. According to some embodiments, each of the three flaps 120A and each of the three flaps 120B are parallel to one another. Each of these three flaps 120A and 120B will create a triangle shaped corner, on each end of front wall 102, once folded. In some embodiments, there may be folding lines, e.g., folding lines 160 separating between one folding flap to another among each three folding flaps, e.g., among each flap of the three folding flaps 120A and the three of folding flaps 120B. [0033]In some embodiments, the first flap 112 extending from front wall 102, may comprise a second flap 132A, which may extend from the first flap 112 from one end (e.g., the right end) of first flap 112, and a second flap 132B, which may extend from first flap 112 from a second end (e.g., the left end) of first flap 112. Second flaps 132A and 132B may be used to support the triangle shaped corner, once cardboard box 100 is in folded state. Each of second flaps 132A and 132B may comprise an extension 122A and 122B, respectively, which may comprise a folding line 162 between the second flaps and their extensions, according to which the extensions 122A and 122B are folded with respect to second flaps, 132A and 132B, respectively. [0034]In some embodiments, the location of first flap 112 may be perpendicular to the location of each of the three flaps 120A and 120B. [0035]In some embodiments, cardboard box 100 may comprise a back wall 104, which may have attached a first flap 114. In some embodiments, between back wall 104 and first flap 114 that extends from back wall 104, may be folding lines 154, which may dictate the location of the folding of first flap 114 over back wall 104, towards what would be the inner side of back wall 104, once cardboard box 100 is in a folded state. Between back wall 1and first flap 114 extending from back wall 104, may be holes 144C and 144D, which may enable ventilation and some air circulation between cardboard boxes, such as cardboard box 100, when the boxes are stacked one over the other. [0036]In some embodiments, back wall 104 may further comprise three flaps 120C extending from a first end (e.g., the left end) of back wall 104, and three flaps 120D extending from a second end (e.g., the right end), typically opposite the first end, of back wall 104. According to some embodiments, each of the three flaps 120C and each of the three flaps 120D are parallel to one another. Each of these three flaps 120C and 120D will create a triangle shaped corner, on each end of back wall 104, once folded. In some embodiments, there may be folding lines, e.g., folding lines 160 separating between one folding flap to another among each three folding flaps, e.g., among each flap of three folding flaps 120C and 120D. [0037]In some embodiments, the first flap 114 extending from back wall 104, may comprise a second flap 132C, which may extend from the first flap 114 from one end (e.g., the left end) of first flap 114, and a second flap 132D, which may extend from first flap 114 from a second end (e.g., the right end) of first flap 114. Second flaps 132C and 132D may be used to support the triangle shaped corner, once cardboard box 100 is in folded state. Each of second flaps 132C and 132D may comprise an extension 122C and 122D, respectively, which may comprise a folding line 164 between the second flaps and their extensions, according to which the extensions 122C and 122D are folded with respect to second flaps, 132C and 132D, respectively. [0038]In some embodiments, the location of first flap 114 may be perpendicular to the location of each of the three flaps 120C and 120D. [0039]In some embodiments, cardboard box 100 may further comprise right side wall 1and left side wall 108, which may be connected to front wall 102 and back wall 104, once cardboard box 100 is in folded state, such to create the closed form of cardboard box 100, ready to carry goods. [0040]Reference is now made to FIGS. 2-7, which are schematic illustrations of an upper perspective view of the folding stages of the spread out cardboard box illustrated in FIG. 1, according to an embodiment of the disclosure. According to FIG. 2, the three flaps 120A, 120B, 120C, and 120D are folded according to folding lines 160, which separate between each of the three folding flaps of each of folding flaps 120A-120D. In some embodiments, each of the three folding flaps 120A and 120B are folded inwardly towards the front wall 102 of cardboard box 100. In some embodiments, each of the three folding flaps 120C and 120D are folded inwardly towards the back wall 104 of cardboard box 100. [0041]In some embodiments, adhesive, e.g., glue, may be applied onto at least one of the three flaps in order to fasten the folded triangle shaped corners onto the skeleton of cardboard box 100. For example, glue 10 may be applied onto flap 180A, which may create the first face of the triangle shaped corner 120A. Flap 180A may be folded inwardly towards front wall 102, and may be glued onto front wall 102. In some embodiments, adhesive may be applied onto flap 182A and onto flap 184A, as part of following steps to create the folded cardboard box 100. Flap 182A may create the second face of the triangle shaped corner 120A, and flap 184A may create the third face of the triangle shaped corner 120A. In some embodiments, glue, e.g., glue 10 may be applied ono flap 180B, in order to fasten comer 120B onto front wall 102. Similarly, glue may be applied onto flap 180C and onto flap 180D in order to fasten these flaps onto back wall 104. In other embodiments, glue is not required. In yet other embodiments, adhesive may be manufactured as part of some of the flaps of cardboard box 100, such that no extra adhesive is to be manually applied during the folding process. Once flap or first face 180A, which in fact creates the first face of the triangle shaped corner 120A, is folded over and connected to front wall 102, front wall 102 supports first face 180A and created a double layer of cardboard at first face 180A. in the same manner front wall 102 supports and provides a double layer to first face 180B, and back wall 1supports and provides a double layer to first face 180C and first face 180D. [0042]FIG. 3 illustrates the triangle shaped corners 120A-120D of cardboard box 100, in folded configuration. In some embodiments, cardboard box 100 may comprise any number of corners from one to four. If cardboard box 100 comprises more than one corner, any location may be applied to the combination of the more than one corner. For example, if there are two corners, the one connected to the first wall, e.g., corner 120A, may be located diagonally to the second corner that may be connected to the back wall, e.g., corner 120C. Typically, cardboard box 100 comprises four corners, two connected to front wall 102, e.g., corners 120A and 120B, and two corners connected to back wall 104, e.g., corners 120C and 120D. [0043]Reference is now made to FIG. 4, which illustrates another stage in the folding process, in which first flap 112 is to be folded over the inner side of front wall 102, and first flap 114 is to be folded over the inner side of back wall 104. In some embodiments, glue may be applied onto the inner side of front wall 102 such that first flap 112 would be tightly connected to it. Similarly, in some embodiments, glue may be applied onto the inner side of back wall 104 such that first flap 114 would be tightly connected to it. In other embodiments, glue may be applied onto first flap 112 and first flap 114, or onto both the front wall 102 and first flap 112, and onto both back wall 104 and first flap 114, or any other combination. [0044]FIG. 5 illustrates first flap 112 after it is folded onto front wall 102, as well as first flap 114 after it is folded onto back wall 104. Accordingly, second flap 132A, which extends from front wall 102, is folded over the second face 182A of corner 120A. Similarly, second flap 132B, which extends from front wall 102 on an end opposite the end from which flap 132A extends, is folded over the second face 182B of corner 120B. At the same manner, second flap 132C, which extends from back wall 104, is folded over the second face 182C of comer 120C. Similarly, second flap 132D, which extends from back wall 104 on an end opposite the end from which flap 132C extends, is folded over the second face 182D of corner 120D. That is, second flap 132A may support second face 182A, such to create a double layer of cardboard at second face 182A. In the same manner, second flap 132B may support second face 182B, such to create a double layer at second face 182B, second flap 132C may support second face 182C, such to create a double layer at second face 182C, and second flap 132D may support second face 182D, such to create a double layer at second face 182D. [0045]According to FIG. 6, front wall 102 may be folded about folding lines 152 (FIG. 1), such to be positioned perpendicular to bottom side 110, and back wall 104 may be folded about folding lines 154 (FIG. 1), such to be positioned perpendicular to bottom side 110. In some embodiments, adhesive may be applied onto third face 184D or onto right side wall 106 or onto both, in order to fasten right side wall 106 onto third face 184D, such to provide support to third face 184D of corner 120D, by creating a double layer of cardboard at third face 184D. In some embodiments, adhesive may be applied onto third face 184C or onto side wall 108 or onto both, in order to fasten side wall 108 onto third face 184C, such to provide support to third face 184C of corner 120C, by creating a double layer of cardboard at third face 184C. [0046]Similarly, in some embodiments, adhesive may be applied onto third face 184A or onto right side wall 106 or onto both, in order to fasten right side wall 106 onto third face 184A, such to provide support to third face 184A of corner 120A, by creating a double layer of cardboard at third face 184A. In some embodiments, adhesive may be applied onto third face 184B or onto side wall 108 or onto both, in order to fasten side wall 108 onto third face 184B, such to provide support to third face 184B of corner 120B, by creating a double layer of cardboard at third face 184B. [0047]Reference is now made to FIG. 7, which schematically illustrates cardboard box 1after the final folding stage, i.e., in folded configuration. In some embodiments, folded cardboard box 100 may comprise a front side 172, a back side 174, a right side 176, and a left side 178. According to some embodiments, once cardboard box 100 is folded, it may comprise at least one double-layered triangle shaped corner. In some embodiments, cardboard box 100 may comprise a first double-layered triangle shaped corner 190A, which may be located on the right end of front side 172, e.g., between front side 172 and right side 176 of cardboard box 100. In some embodiments, cardboard box 100 may comprise a second double-layered triangle shaped comer 190B, which may be located on the left end of front side 172, e.g., between front side 172 and left side 178 of cardboard box 100. In some embodiments, cardboard box 100 may comprise a third double-layered triangle shaped corner 190C, which may be located on the left end of back side 174, e.g., between back side 174 and left side 178 of cardboard box 100. In some embodiments, cardboard box 100 may comprise a fourth double-layered triangle shaped corner 190D, which may be located on the right end of back side 174, e.g., between back side 174 and right side 176 of cardboard box 100. [0048]In some embodiments, there may be overlap between extension 122A and right side wall 106, as well as overlap between extension 122D and right side wall 106, thereby right side wall 106 may be at least partially double-layered, thus reinforced compared to a single layered wall. [0049]In some embodiments, there may be overlap between extension 122B and left side wall 108, as well as overlap between extension 122C and left side wall 108, thereby left side wall 108 may be at least partially double-layered, thus reinforced compared to a single layered wall. [0050]Reference is now made to FIG. 8, which is a schematic illustration of an upper-side perspective view of the folded cardboard box, according to an embodiment of the disclosure. FIG. 8 schematically illustrates the double-layered triangle shaped corner 190A in detail. In some embodiments, double-layered triangle shaped corner 190A may comprise first face 180A connected to front wall 102, such to create a double layer of cardboard for the first face 180A. In some embodiments, corner 190A may comprise second face 182A, which may be connected to second flap 132A extending from first flap 112, which extends from front wall 102. The presence of second flap 132A in close proximity to second face 182A creates a double layer of cardboard for second face 182A. In some embodiments, corner 190A may further comprise third face 184A, which may be connected to right side wall 106, such to create a double layer of cardboard for third face 184A. That is, double-layered triangle shaped corner 190A comprises a double layer of cardboard on all sides or faces of the triangle shaped corner 120A, thereby double-layered triangle shaped corner 190A is properly reinforced and would stay intact during usage of cardboard box 100. [0051]In the same manner, double-layered triangle shaped corners 190B-190D may comprise a double layer of cardboard on all sides or faces of the triangle shaped corners 120B-120D, respectively, thereby double-layered triangle shaped comers 190B-190D are properly reinforced and would stay intact during usage of cardboard box 100. [0052]In some embodiments, and as mentioned above, front side 172 may be a double­layered front side, by folding first flap 112, which extends from front wall 102 onto front wall 102, thereby bringing first flap 112 into close proximity with front wall 102. Accordingly, first flap 112 may support front wall 102, and create a double-layered front side 172, which properly reinforce front side 172 to keep it intact during usage of cardboard box 100. [0053]In some embodiments, and as mentioned above, back side 174 may be a double­layered back side, by folding first flap 114, which extends from back wall 104 onto back wall 104, thereby bringing first flap 114 into close proximity with back wall 104. Accordingly, first flap 114 may support back wall 104, and create a double-layered back side 174, which properly reinforce back side 174 to keep it intact during usage of cardboard box 100. [0054]Thus, according to embodiments of the disclosure, cardboard box 100 may be reinforced by having a double layer of cardboard in any of the triangle shaped corners of cardboard box 100 (e.g., double-layered triangle shaped corners 190A, 190B, 190C and 190D), as well as be reinforced by having a double layer of cardboard at the front side and at the back side of cardboard box 100. Such reinforcements strengthen cardboard box 100, and assist in maintaining cardboard box 100 intact during the entire usage of cardboard box 100, e.g., during packaging goods into cardboard box 100, during transportation of the goods within cardboard box 100, and so on. At the end of usage of cardboard box 100, it may easily be recycled since it only consists of cardboard, which is a known recyclable material. [0055]Reference is now made to FIG. 9, which is a schematic illustration of an upper perspective view of a spread out cardboard box according to another embodiment of the disclosure. In some embodiments, there may be another configuration of a reinforced cardboard box in addition to cardboard box 100, e.g., cardboard box 200. The spreading or layout of cardboard box 200 may be somewhat different from the spreading or layout of cardboard box 100, thus resulting in a somewhat different folded configuration, compared to that of cardboard box 100. However, the similarities between folded configuration cardboard box 100 and folded configuration cardboard box 200 is that they may both comprise at least one double-layered triangle shaped corner, and double-layered back side and front side. In some embodiments, each of the right side and the left side of cardboard box 200 may comprise a partial double layer of cardboard, due to partial overlap between each of the right side wall and the left side wall with extensions or flaps of cardboard box 200. [0056]According to some embodiments, cardboard box 200 may comprise section 210, which may become the bottom side of cardboard box 200, once cardboard box 200 is folded. In some embodiments, bottom side 210 may comprise holes, such as holes 240. According to some embodiments, holes, such as holes 240 may provide ventilation and air circulation between each cardboard box to another, specifically when the cardboard boxes are stacked one over the other. In some embodiments, cardboard box 200 may comprise a front wall 202, which may have attached a first flap 212. In some embodiments, between front wall 202 and first flap 212 that extends from front wall 202, may be folding lines 252, which may dictate the location of the folding of first flap 212 over front wall 202, towards what would be the inner side of front wall 202, once cardboard box 200 is in a folded state. [0057]In some embodiments, front wall 202 may comprise a hole 244, which may enable ventilation and some air circulation between cardboard boxes, such as cardboard box 200, when the boxes are stacked one over the other. [0058]In some embodiments, front wall 202 may further comprise three flaps 220A extending from a first end of front wall 202, and three flaps 220B extending from a second end, typically opposite the first end, of front wall 202. For example, three flaps 220A may be extend from front wall 202 from the right side of front wall 202, while three flaps 220B may extend from front wall 202 from the left side of front wall 202. According to some embodiments, each of the three flaps 220A and each of the three flaps 220B are positioned parallel to one another. Each of these three flaps 220A and 220B may create a triangle shaped corner, on each end of front wall 202, once folded. In some embodiments, there may be folding lines, e.g., folding lines 260 separating between one folding flap to another among each three folding flaps, e.g., among each flap of the three folding flaps 220A and the three of folding flaps 220B. [0059]In some embodiments, the first flap 212 extending from front wall 202, may comprise a second flap 232A, which may extend from the first flap 212 from one end of first flap 2(e.g., from the right end of first flap 212). In some embodiments, first flap 212 may comprise a second flap 232B, which may extend from first flap 212 from a second end of first flap 2(e.g., from the left end of first flap 212). Second flaps 232A and 232B may be used to support the triangle shaped corner, once cardboard box 200 is in folded state, as will be detailed with respect to FIGS. 13-15. Each of second flaps 232A and 232B may comprise an extension 222A and 222B, respectively, which may comprise a folding line 262 between the second flaps and their extensions, according to which the extensions 222A and 222B may be folded with respect to second flaps, 232A and 232B, respectively. [0060]In some embodiments, the location of first flap 212 may be perpendicular to the location of each of the three flaps 220A and 220B. [0061]In some embodiments, cardboard box 200 may comprise a back wall 204, which may have attached a first flap 214. In some embodiments, between back wall 204 and first flap 214 that extends from back wall 204, may be folding lines 254, which may dictate the location of the folding of first flap 214 over back wall 204, towards what would be the inner side of back wall 204, once cardboard box 200 is in a folded state. In some embodiments, back wall 204 may comprise hole 244, which may enable ventilation and some air circulation between cardboard boxes, such as cardboard box 200, when the boxes are stacked one over the other. [0062]In some embodiments, back wall 204 may further comprise three flaps 220C extending from a first end (e.g., the left end) of back wall 204, and three flaps 220D extending from a second end (e.g., the right end), typically opposite the first end, of back wall 204. According to some embodiments, each of the three flaps 220C and each of the three flaps 220D are parallel to one another. Each of these three flaps 220C and 220D will create a triangle shaped corner, on each end of back wall 204, once folded. In some embodiments, there may be folding lines, e.g., folding lines 260 separating between one folding flap to another among each three folding flaps, e.g., among each flap of three folding flaps 220C and 220D. [0063]In some embodiments, the first flap 214 extending from back wall 204, may comprise a second flap 232C, which may extend from the first flap 214 from one end (e.g., the left end) of first flap 214. In some embodiments, first flap 214 may comprise a second flap 232D, which may extend from first flap 214 from a second end (e.g., the right end) of first flap 214. Second flaps 2132C and 232D may be used to support the triangle shaped corner, once cardboard box 200 is in folded state. Each of second flaps 232C and 232D may comprise an extension 222C and 222D, respectively, which may comprise a folding line 264 between the second flaps and their extensions, according to which the extensions 222C and 222D are folded with respect to second flaps, 232C and 232D, respectively. id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64" id="p-64"

[0064]In some embodiments, the location of first flap 214 may be perpendicular to the location of each of the three flaps 220C and 220D. [0065]In some embodiments, cardboard box 200 may further comprise right side wall 2and left side wall 208, which may be connected to front wall 202 and back wall 204, once cardboard box 200 is in folded state, such to create the closed form of cardboard box 200, ready to carry goods. [0066]Reference is now made to FIGS. 10-14, which are schematic illustrations of an upper perspective view of the folding stages of the spread out cardboard box illustrated in FIG. 9, according to an embodiment of the disclosure. [0067]According to FIG. 10, the three flaps 220A, 220B, 220C, and 220D may be folded according to folding lines 260 (FIG. 9), which separate between each of the three folding flaps of each of folding flaps 220A-220D. In some embodiments, each of the three folding flaps 220A and 220B are folded inwardly towards the front wall 202 of cardboard box 200. In some embodiments, each of the three folding flaps 220C and 220D are folded inwardly towards the back wall 204 of cardboard box 200. [0068]In some embodiments, adhesive, e.g., glue, may be applied onto at least one of the three flaps in order to fasten the folded triangle shaped corners onto the skeleton of cardboard box 200. For example, glue 10 may be applied onto flap 280A, which may create the first face of the triangle shaped corner 220A. Flap 280A may be folded inwardly towards front wall 202, and may be glued onto front wall 202. In some embodiments, adhesive may be applied onto flap 282A and onto flap 284A, as part of following steps to create the folded cardboard box 200. Flap 282A may create the second face of the triangle shaped corner 220A, and flap 284A may create the third face of the triangle shaped corner 220A. In some embodiments, glue, e.g., glue 10 may be applied ono flap 280B, in order to fasten corner 220B onto front wall 202. Similarly, glue may be applied onto flap 280C and onto flap 280D in order to fasten these flaps onto back wall 204. In other embodiments, glue is not required. In yet other embodiments, adhesive may be manufactured as part of some of the flaps of cardboard box 200, such that no extra adhesive is to be manually applied during the folding process. Once flap or first face 280A, which in fact creates the first face of the triangle shaped corner 220A, is folded over and connected to front wall 202, front wall 202 may support first face 280A and create a double layer of cardboard at first face 280A. In the same manner, front wall 202 may support and provide a double layer to first face 280B, and back wall 2may support and provide a double layer to first face 280C and first face 280D. id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69" id="p-69"

[0069]FIG. 11 illustrates the triangle shaped comers 220A-220D of cardboard box 200, in folded configuration. In some embodiments, cardboard box 200 may comprise at least one triangle shaped corner. In some embodiments, cardboard box 200 may comprise any number of corners from one to four. In case cardboard box 200 comprises more than one corner, any location may be applied to the combination of the more than one corner. For example, if there are two corners, the one connected to the first wall, e.g., corner 1220A, may be located diagonally to the second corner that may be connected to the back wall, e.g., corner 220C. Typically, cardboard box 200 comprises four corners, two connected to front wall 202, e.g., corners 220A and 220B, and two corners connected to back wall 204, e.g., corners 220C and 220D. [0070]Reference is now made to FIG. 12, which illustrates another stage in the folding process, in which first flap 212 is to be folded over the inner side of front wall 202 about folding lines 252, and first flap 214 is to be folded over the inner side of back wall 204, about folding lines 254. In some embodiments, glue may be applied onto the inner side of front wall 202 such that first flap 212 would be tightly connected to it. Similarly, in some embodiments, glue may be applied onto the inner side of back wall 204 such that first flap 214 would be tightly connected to it. In other embodiments, glue may be applied onto first flap 212 and first flap 214, or onto both the front wall 202 and first flap 212, and onto both back wall 204 and first flap 214, or any other combination. [0071]FIG. 13 illustrates first flap 212 after it is folded onto front wall 202, as well as first flap 214 after it is folded onto back wall 204. Accordingly, second flap 232A, which extends from front wall 202, is folded over the second face 282A of corner 220A. Similarly, second flap 232B, which extends from front wall 202 on an end (e.g., the left end) opposite the end from which flap 232A extends (e.g., the right end), is folded over the second face 282B of corner 220B. At the same manner, second flap 232C, which extends from back wall 204, is folded over the second face 282C of corner 220C. Similarly, second flap 232D, which extends from back wall 204 on an end (e.g., the right end) opposite the end from which flap 232C extends (e.g., the left end), is folded over the second face 282D of corner 220D. That is, second flap 232A may support second face 282A, such to create a double layer of cardboard at second face 282A. In the same manner, second flap 232B may support second face 282B, such to create a double layer at second face 282B, second flap 232C may support second face 282C, such to create a double layer at second face 282C, and second flap 232D may support second face 282D, such to create a double layer at second face 282D. id="p-72" id="p-72" id="p-72" id="p-72" id="p-72" id="p-72" id="p-72" id="p-72" id="p-72" id="p-72" id="p-72"

[0072]According to FIG. 14, front wall 202 may be folded about folding lines 252 (FIG. 9), such to be positioned perpendicular to bottom side 210, and back wall 204 may be folded about folding lines 254 (FIG. 9), such to be positioned perpendicular to bottom side 210. In some embodiments, adhesive may be applied onto third face 284A or onto right side wall 206 or onto both, in order to fasten right side wall 206 onto third face 284A, such to provide support to third face 284A of corner 220A, by creating a double layer of cardboard at third face 284A. In some embodiments, adhesive may be applied onto third face 284B or onto side wall 1208 or onto both, in order to fasten side wall 208 onto third face 184B, such to provide support to third face 284CB of corner 220B, by creating a double layer of cardboard at third face 284B. [0073]Similarly, in some embodiments, adhesive may be applied onto third face 184D or onto right side wall 206 or onto both, in order to fasten right side wall 206 onto third face 284D, such to provide support to third face 284D of corner 120D, by creating a double layer of cardboard at third face 284D. In some embodiments, adhesive may be applied onto third face 284C or onto side wall 208 or onto both, in order to fasten side wall 208 onto third face 284C, such to provide support to third face 284C of corner 220C, by creating a double layer of cardboard at third face 284C. [0074]Reference is now made to FIG. 15, which schematically illustrates cardboard box 200 after the final folding stage, i.e., in folded configuration. In some embodiments, folded cardboard box 200 may comprise a front side 272, a back side 274, a right side 276, and a left side 278. According to some embodiments, once cardboard box 200 is folded, it may comprise at least one double-layered triangle shaped corner. In some embodiments, cardboard box 200 may comprise a first double-layered triangle shaped corner 290A, which may be located on the right end of front side 272, e.g., between front side 272 and right side 276 of cardboard box 200. In some embodiments, cardboard box 200 may comprise a second double-layered triangle shaped corner 290B, which may be located on the left end of front side 272, e.g., between front side 272 and left side 278 of cardboard box 100. In some embodiments, cardboard box 200 may comprise a third double-layered triangle shaped corner 290C, which may be located on the left end of back side 274, e.g., between back side 274 and left side 278 of cardboard box 200. In some embodiments, cardboard box 200 may comprise a fourth double-layered triangle shaped corner 290D, which may be located on the right end of back side 274, e.g., between back side 274 and right side 276 of cardboard box 200. id="p-75" id="p-75" id="p-75" id="p-75" id="p-75" id="p-75" id="p-75" id="p-75" id="p-75" id="p-75" id="p-75"

[0075]In some embodiments, there may be overlap between extension 222A and right side wall 206, as well as overlap between extension 222D and right side wall 206, thereby right side wall 206 may be at least partially double-layered, thus reinforced compared to a single layered wall. [0076]In some embodiments, there may be overlap between extension 222B and left side wall 208, as well as overlap between extension 222C and left side wall 208, thereby left side wall 208 may be at least partially double-layered, thus reinforced compared to a single layered wall. [0077]FIG. 15 further illustrates the double-layered triangle shaped corner 290A in detail. In some embodiments, double-layered triangle shaped corner 290A may comprise first face 280A connected to front wall 202, such to create a double layer of cardboard for the first face 280A. In some embodiments, corner 290A may comprise second face 282A, which may be connected to second flap 232A extending from first flap 212, which extends from front wall 202. The presence of second flap 232A in close proximity to second face 282A creates a double layer of cardboard for second face 282A. In some embodiments, corner 290A may further comprise third face 284A, which may be connected to right side wall 206, such to create a double layer of cardboard for third face 284A. That is, double-layered triangle shaped corner 290A comprises a double layer of cardboard on all sides or faces of the triangle shaped corner 220A, thereby double-layered triangle shaped corner 290A is properly reinforced and would stay intact during usage of cardboard box 200. [0078]In the same manner, double-layered triangle shaped corners 290B-290D may comprise a double layer of cardboard on all sides or faces of the triangle shaped corners 220B-220D, respectively, thereby double-layered triangle shaped corners 290B-290D are properly reinforced and would stay intact during usage of cardboard box 200. [0079]In some embodiments, and as mentioned above, front side 272 may be a double­layered front side, by folding first flap 212, which extends from front wall 202 onto front wall 202, thereby bringing first flap 212 into close proximity with front wall 202. Accordingly, first flap 212 may support front wall 202, and create a double-layered front side 272, which properly reinforce front side 272 to keep it intact during usage of cardboard box 200. [0080]In some embodiments, and as mentioned above, back side 274 may be a double­layered back side, by folding first flap 214, which extends from back wall 204 onto back wall 204, thereby bringing first flap 214 into close proximity with back wall 204.

Accordingly, first flap 214 may support back wall 204, and create a double-layered back side 274, which may properly reinforce back side 274 to keep it intact during usage of cardboard box 200. [0081]Thus, according to embodiments of the disclosure, cardboard box 200 may be reinforced by having a double layer of cardboard in any of the triangle shaped corners of cardboard box 200, (e.g., double-layered triangle shaped corners 290A, 290B, 290C and 290D), as well as be reinforced by having a double layer of cardboard at the front side and at the back side of cardboard box 200. Such reinforcements strengthen cardboard box 200, and assist in maintaining cardboard box 200 intact during the entire usage of cardboard box 200, e.g., during packaging goods into cardboard box 200, during transportation of the goods within cardboard box 200, and so on. At the end of usage of cardboard box 200, it may easily be recycled since it only consists of cardboard, which is a known recyclable material. [0082]Reference is now made to FIG. 16, which is a schematic flowchart illustrating a method for reinforcing a cardboard box, according to an embodiment of the disclosure.
