Description

Technical Field

[0001] This application relates to the field of storage box technology, and more specifically, to a foldable storage box. Background Technology

[0002] Storage boxes are commonly used to store and transport various items, but they take up a lot of space when empty, and simply discarding them results in a waste of resources. Therefore, a box that can be freely folded, assembled, and disassembled is essential. That is, in its initial state or after disassembly, it is a flat board shape, and when needed, its various side panels are folded into a complete box in a predetermined order.

[0003] When these types of storage boxes are used in stores or on shelves, multiple layers are usually stacked to better display items and save space. However, when stacking boxes, the upper layers are prone to slipping because there is no restraining structure. Therefore, various types of support systems are needed to secure the boxes in place.

[0004] Existing related technologies, such as US11591130B1, entitled "Stackable and Foldable Box," typically include a base plate, a U-shaped front panel foldably connected to the base plate and defining a display opening, and a rear panel foldably connected to the base plate; first and second side panels are further foldably connected to a bottom panel and include retaining flaps for securing the first and second side panels to the front and rear panels; protrusions extend upward from the first and second sides, and cutouts are formed along the bottom edges of the first and second sides; protrusions are configured to engage with cutouts formed in a second box located at the top of the box to secure or lock the upper and lower boxes together to prevent slippage between them. When stacking such foldable boxes, the protrusions on the left and right sides of the top of the box must be aligned simultaneously with the bottom cutouts of the upper box before insertion to achieve stacking and fixation, which is inconvenient during operation. Summary of the Invention

[0005] The technical problem to be solved by this application is to overcome at least one of the defects of the above-mentioned related technologies and provide a foldable storage box that simplifies the positioning difficulty when the boxes need to be stacked and improves work efficiency.

[0006] The technical solution of this application is to provide a foldable storage box: including...

[0007] The box comprises a base plate, a front panel, a rear panel, a left side panel, and a right side panel. The front panel, rear panel, left side panel, and right side panel are foldable and connected to the front edge, rear edge, left edge, and right edge of the base plate, respectively. After folding and assembly, the base plate, front panel, rear panel, left side panel, and right side panel define the internal space of the box, and the front side of the box includes a front opening that communicates with the internal space.

[0008] The left and right top plates are foldable and connected to the edge of the left side plate away from the bottom plate. The right top plate is foldable and connected to the edge of the right side plate away from the bottom plate. When folded, the left and right top plates form two supporting top plates on the left and right sides of the box body. One of the supporting top plates is provided with an upper Velcro fastener. The bottom plate of the box body is provided with a lower Velcro fastener symmetrically above and below the upper Velcro fastener. The other supporting top plate is provided with a protruding positioning insert plate. The bottom plate of the box body is provided with positioning holes symmetrically above and below the positioning insert plate.

[0009] In some embodiments, the front panel and the rear panel are respectively connected by a left front flap, a right front flap, a left rear flap, and a right rear flap that can be folded along their end edges. After folding, the left front flap and the left rear flap are respectively attached to the inner wall of the left side panel of the housing, and the right front flap and the right rear flap are respectively attached to the inner wall of the right side panel of the housing. At least one positioning through hole is provided on the left top panel near the edge of the left side panel, and the corresponding left front flap and / or left rear flap are provided with an insert protrusion. After folding, the insert protrusion is inserted vertically upward through the positioning through hole to form the positioning insert. The right top panel is provided with an upper Velcro fastener.

[0010] In some embodiments, the lower ends of the left front flap, right front flap, left rear flap and right rear flap are provided with lower insertion blocks, and the left and right ends of the base plate are provided with lower insertion holes near the edges of the left and right side plates. After folding, each of the lower insertion blocks is inserted and positioned vertically downward in the corresponding lower insertion hole, and the bottom plane of each of the lower insertion blocks is flush with the bottom surface of the base plate.

[0011] In some embodiments, the upper ends of the left front flap, right front flap, left rear flap and right rear flap are provided with upper insertion blocks, and the left top plate and right top plate are respectively provided with upper insertion holes. After folding, each upper insertion block is inserted and positioned vertically upward in the corresponding upper insertion hole, and the top plane of each upper insertion block is flush with the top surface of the left top plate and the right top plate.

[0012] In some embodiments, the front and rear ends of the left top plate are respectively connected to a left front wing plate and a left rear wing plate, which can be folded along their end edges and are respectively connected to the front panel and the rear panel; the front and rear ends of the right top plate are respectively connected to a right front wing plate and a right rear wing plate, which can be folded along their end edges and are respectively connected to the front panel and the rear panel.

[0013] In some embodiments, the front panel includes a bottom, a first side extending upward from the left end of the bottom to the top of the housing, and a second side extending upward from the right end of the bottom to the top of the housing, the first side, the second side, and the bottom forming a U-shaped structure, and the interior of the U-shaped structure defining the front opening, the upper surface of the bottom being higher than the base plate.

[0014] In some embodiments, the end of the bottom away from the base plate is connected to an extension panel that can be folded along its edge and connected to the base plate, and after folding, the extension panel abuts against the inner sidewall of the bottom; the bottom and the folded portion of the extension panel form a horizontal plane.

[0015] In some embodiments, the ends of the left front wing and left rear wing away from the left top plate, and the ends of the right front wing and right rear wing away from the right top plate are all connected to insert fasteners that can be folded along their end edges. The left and right ends of the front panel and the rear panel, near the bottom plate, are provided with insertion holes for the corresponding insert fasteners to be inserted and fitted. After folding, the left front wing and right front wing are respectively attached to the front walls of the first side and the second side, and the left rear wing and right rear wing are respectively attached to the outer walls of the two sides of the rear panel.

[0016] In some embodiments, the top of the first side and the second side near the front opening, as well as the top of the left and right sides of the rear panel, are provided with recessed limiting steps; the left front wing plate and the left rear wing plate near the left top plate, as well as the right front wing plate and the right rear wing plate near the right top plate, are provided with clearance notches, and after the box body is folded and assembled, the bottom sides of each clearance notch fold and fit on the corresponding limiting steps.

[0017] In some embodiments, the left front wing and the right front wing are each connected to a foldable insert fastener at the edge away from the front opening, and the left rear wing and the right rear wing are each connected to a foldable insert fastener at one end near the sides of the housing. Corresponding insert holes are provided at the corresponding positions on the left and right ends of the front panel and the rear panel.

[0018] In summary, compared with related technologies, the foldable storage box and TV lift cabinet structure proposed in this application have the following advantages:

[0019] 1. After folding and assembling, the storage box structure of this application forms a horizontal left top plate and a right top plate on the top of the left and right sides of the box body. A protruding positioning insert plate is formed only on the left top plate, and correspondingly, positioning holes symmetrical to the positioning insert plate are formed on the bottom plate of the box body. The right top plate has an upper Velcro fastener; or a protruding positioning insert plate is formed on the right top plate, and correspondingly, positioning holes symmetrical to the positioning insert plate are formed on the bottom plate of the box body. The left top plate has an upper Velcro fastener. In this way, when stacking the upper and lower boxes, it is only necessary to align the protrusion on the top of one side of the top plate with the cut on the bottom plate of the upper folding box and insert it. The upper Velcro fastener on the other side of the top plate is then glued to the lower Velcro fastener on the bottom surface of the upper box body to achieve stacking and fixation. It is not necessary to align and insert both sides, simplifying the operation difficulty when stacking.

[0020] 2. After folding, the left and right sides of both ends of the box have wing plate structures, and each wing plate is inserted and positioned with the front and rear panels through multiple plug-in structures, which makes the structure stable; and the two wing plates at the front of the box are completely attached to the two sides of the front panel, further increasing the structural strength of the front panel of the box.

[0021] 3. The upper end of the flap on the left or right side of the enclosure is provided with an insert protrusion that passes through the corresponding top plate to form a positioning insert plate, and the upper end of the corresponding flap also has an insert structure that is inserted and positioned with the top plate. That is, the flap positioning structure and the positioning insert plate forming structure are independent of each other, ensuring the stability of the enclosure structure.

[0022] 4. The left front wing plate, left rear wing plate, right front wing plate, and right rear wing plate are limited by limiting steps and avoidance gaps at the top of the front and rear panels of the box. In addition, the insertion structure between the left front wing plate and the corresponding first and second sides on both sides of the left front wing plate and the right front wing plate, as well as the insertion structure between the left rear wing plate and the rear panel on both sides, effectively limits the left and right position of each wing plate structure after it is inserted into the corresponding panel, thereby improving the structural strength of the box.

[0023] Other improvements and advantages of this application will be set forth in the following detailed description and will be apparent in part from the specification or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained through the structures particularly pointed out in the specification and drawings. Attached Figure Description

Detailed Implementation

[0031] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0032] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0033] In the embodiments of this application, unless otherwise explicitly specified and limited, the first feature at the "upper end" or "lower end" of the second feature may be in direct contact with the first feature, or indirect contact with the first feature through an intermediate medium. Moreover, the first feature "below" or "below" the second feature may mean that the first feature is directly below or diagonally below the second feature, or simply that the horizontal height of the first feature is less than that of the second feature.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] See Figures 1-5 As shown in the figure, this application discloses a foldable storage box. The following is a detailed description of the storage box in its initial flat or unfolded state.

[0036] It includes a base plate 1, a front panel 2, a rear panel 3, a left side panel 4, and a right side panel 5. The front panel 2, rear panel 3, left side panel 4, and right side panel 5 are foldably connected to the front edge, rear edge, left edge, and right edge of the base plate 1, respectively. Additionally, a notch is provided in the middle of the end of the front panel 2 furthest from the base plate 1, giving the front panel 2 a roughly U-shaped structure. Specifically, the front panel 2 includes a bottom 200, a first side 201 extending upwards from the left end of the bottom 200 to the top of the housing, and a side portion 201 extending upwards from the right end of the bottom 200. The second side 202 extending to the top of the box, the first side 201, the second side 202 and the bottom 200 form a U-shaped structure, and the interior of the U-shaped structure defines the front opening. The upper surface of the bottom 200 is higher than the bottom plate 1. When folded, the front panel 2, the rear panel 3, the left side panel 4 and the right side panel 5 are folded in the same direction along the edge folding lines around the bottom plate 1 until they are basically perpendicular to the bottom plate 1, thereby forming a box with a top and front opening for storing folded clothing or other items. The front opening makes it easy to reach and put in items.

[0037] More specifically, to ensure the folded box has sufficient structural strength and won't easily fall apart, left rear flaps 14 and right rear flaps 15 are provided at both ends of the rear panel, capable of folding along their respective edges. These flaps are independent and not connected to the rear sides of the left and right side panels 4 and 5. Similarly, left front flaps 12 and right front flaps 13 are provided at both ends of the front panel 2, capable of folding along their respective edges. The front sides of the left side panel 4 and the right side panel 5 are also independent and not connected to each other; and when the box is folded and assembled, the left front flap 12 is folded to be close to the front inner wall of the left side panel 4, the left rear flap 14 is folded to be close to the rear inner wall of the left side panel 4, the right front flap 13 is folded to be close to the front inner wall of the right side panel 5, and the right rear flap 15 is folded to be close to the rear inner wall of the right side panel 5, so as to increase the structural strength of the box. After folding, the height of each flap is roughly the same as the height of each side panel.

[0038] In some other embodiments, when the initial sheet metal is in its initial state, the left rear flap 14, the right rear flap 15 and the left and right side panels 5, as well as the left front flap 12, the right front flap 13 and the left and right side panels 5, can also be connected by tearable stitches. During later folding and assembly, these stitches can be manually torn before folding.

[0039] On the other hand, in order to facilitate stable stacking between multi-layer boxes, in this embodiment, a left top plate 6 that can be folded along its edge is connected to the end of the left side plate 4 away from the bottom plate 1, and a right top plate 7 that can be folded along its edge is connected to the end of the right side plate 5 away from the bottom plate 1. Specifically, a left upper front insertion hole 25 and a left upper rear insertion hole 26 staggered are provided on the edge of the left top plate 6 near the left side plate 4, and a right upper front insertion hole 27 and a right upper rear insertion hole 28 staggered are provided on the side of the right top plate 7 near the right side plate 5. Correspondingly, on the side of the left front flap 12 and the left rear flap 14 away from the left side plate 4, and on the side of the right front flap 13 and the right rear flap 15 away from the right side plate 5, a first insertion block 29 that is inserted into the left upper front insertion hole 25 and the left upper rear insertion hole 26, respectively, are formed protrudingly. The second insert 30, the third insert 31 which is inserted into the upper right front insert hole 27, and the fourth insert 32 which is inserted into the upper right rear insert hole 28 are all fitted together. After the box is folded flat, the left top plate 6 and the right top plate 7 are folded towards the middle of the box until they are roughly horizontal, so that the top of the left and right sides of the box forms a support plate of a certain width. The four inserts are vertically inserted into the four corresponding insert holes, and the upper surface of each insert is basically flush with the upper surface of the left and right top plates 7. In this structure, after each insert is inserted into its corresponding upper insert hole, the flaps on the left and right sides can be connected and positioned with the corresponding side plates, and will not come off or shake, thus ensuring the structural strength of the box. In addition, the left and right support plates can better ensure the flatness of the contact surface when multiple boxes are stacked, thereby improving stability.

[0040] Furthermore, in this embodiment, an upper Velcro 8 is provided on the left top plate 6 of the box, and a protruding positioning insert 10 is provided on the right top plate 7. A lower Velcro 9 is provided on the lower end surface of the bottom plate 1 at a position corresponding to the upper Velcro 8, and a positioning insertion hole 11 is provided at a position corresponding to the positioning insert 10. Thus, when two boxes are stacked, one side is fixed by the upper and lower Velcro 9, and the other side is positioned by the insertion of the positioning insert 10 and the positioning insertion hole 11, achieving stability after the upper and lower boxes are stacked. In the above structure, the positions of the Velcro positioning and the insertion structure positioning can be interchanged.

[0041] In the above structure, the upper and lower Velcro straps 9 can be pre-attached to corresponding positions on the flat panel before folding the case, or they can be attached to the corresponding top panel after the case is assembled; there is no limitation here. Specifically, the following is a detailed explanation using an example where Velcro is located on the right side of the case and the left side is positioned by inserts:

[0042] A first positioning through hole 161 and a second positioning through hole 162 are provided at the edge of the left top plate 6 near the left side plate 4, which are staggered front and rear. A first insert plate 171 and a second insert plate 172 are respectively provided at the middle part of the left front flap 12 and the left rear flap 14 away from the left side plate 4. When the box is folded and assembled into a rectangular structure according to the set shape, the first insert plate 171 at the top of the left front flap 12 passes vertically through the first positioning through hole 161, and the second insert plate 172 at the top of the left rear flap 14 passes vertically through the second positioning through hole 162. The height of the first insert plate 171 and the second insert plate 172 is higher than the thickness of the right top plate 7. Therefore, after the two insert plates 17 are inserted and positioned with the two positioning through holes 16, the part of the insert plate 17 that extends beyond the right top plate 7 of the box forms the front and rear positioning insert plates 10. Correspondingly, a staggered positioning insertion hole 11 is provided on the edge of the bottom plate 1 near the right side plate 5, and the positions of the two positioning insertion holes 11 correspond vertically to the positions of the two positioning plates 10. More specifically, in this structure, a clearance groove is provided in the middle of the left front flap 12 and the left rear flap 14 near the left side plate 4. After the box is folded and assembled, two clearances are formed at the lower end of the left side wall of the box and the corresponding positions of the two positioning insertion holes 11, so that when the two boxes are stacked, the positioning plate 10 on the top of the lower box can be smoothly inserted into the positioning insertion hole 11 on the bottom plate 1 of the upper box.

[0043] To ensure that after the box is folded and formed, each flap remains in contact with the inner wall of its corresponding side panel and does not detach when unfolded; see appendix. Figure 1 On the bottom plate 1 near the edge of the left side plate 4, there are left lower front insertion holes 33 and left lower rear insertion holes 34 staggered from front to back. On the bottom plate 1 near the edge of the right side plate 5, there are right lower front insertion holes 35 and right lower rear insertion holes 36 staggered from front to back. Correspondingly, on the left front flap 12 and left rear flap 14 near the left side plate 4, and on the right front flap 13 and right rear flap 15 near the right side plate 5, there are respectively a fifth insertion block 37 that is inserted into the left lower front insertion hole 33 and a sixth insertion block that is inserted into the left lower rear insertion hole 34. Block 38, the seventh insert block 39 which is inserted into the lower right front insert hole 35, and the eighth insert block 40 which is inserted into the lower right rear insert hole 36; the above insertion structure further realizes the connection limit between the lower end of each side panel of the box and the bottom plate 1; and after the corresponding insert blocks at the lower end of each flap are vertically inserted into the corresponding insert holes, the lower end surface of each insert block is basically flush with the lower end surface of the bottom plate 1; in this structure, after the lower end of each flap is inserted into the corresponding lower insert hole through each insert block, the connection structure with the left and right side panels is more stable and not easy to detach from the side panels and shake.

[0044] In this embodiment, see Appendix Figure 1 , 23. A left front wing panel 18 and a left rear wing panel 19, foldable along their edges, are connected to the front and rear ends of the left top panel 6. When the box is in the unfolded state, the left front wing panel 18 and the left rear wing panel 19 both have a first insert fastener 41 and a second insert fastener 42 protruding outwards at the ends away from the left top panel 6. The left front wing panel 18 has a third insert fastener 43 protruding outwards at the middle of the end near the left front flap 12, and the left rear wing panel 19 has a fourth insert fastener 44 protruding outwards at the middle of the end near the left and right flaps. Correspondingly, a first insert hole 45 and a second insert hole 46 extending towards the front panel 2 or rear panel 3 are respectively provided at the front and rear ends of the left side of the bottom panel 1 where it connects to the front panel 2 and rear panel 3. At the edge of the front panel 2 near the left front flap 12... A third insertion hole 47 is provided, and a fourth insertion hole 48 is provided on the rear panel 3 near the edge of the left rear flap 14. After the side panels of the box are folded to the vertical position and the flaps are also folded to the corresponding positions, the left top panel 6 is first folded towards the middle of the box to the horizontal position. Then, the left front flap 18 and the left rear flap 19 are folded down from top to bottom to the vertical position. Next, the first insertion fastener 41 on the left front side of the box is inserted into the first insertion hole 45, the third insertion fastener 43 is inserted into the third insertion hole 47, and finally the second insertion fastener 42 on the left rear side of the box is inserted into the second insertion hole 46, and the fourth insertion fastener 44 is inserted into the fourth insertion hole 48, which further strengthens the connection between the left top panel 6, the left side panel 4, and the bottom panel 1 of the box.

[0045] Similarly, right front wing 20 and right rear wing 21, which can be folded along their edges, are connected to the front and rear ends of the right top plate 7. This connection structure is the same as that on the left side of the box body. Specifically, in this structure, a fifth insert fastener 49 is provided on the side of the right front wing 20 away from the right top plate 7, and a seventh insert fastener 51 is provided on the side near the right front flap 13. Similarly, a sixth insert fastener 50 is provided on the side of the right rear wing 21 away from the right top plate 7, and an eighth insert fastener 52 is provided on the side near the right rear flap 15. Correspondingly, a fifth insert hole 53 and a sixth insert hole 54 are provided at the corresponding positions where the bottom plate 1 connects to the front and rear panels 3. On the front panel 2... A seventh insertion hole 55 is provided near the edge of the right front flap 13, and an eighth insertion hole 56 is provided near the edge of the right rear flap 15 on the rear panel 3. After the box is assembled and the left top plate 6 is folded towards the middle of the box to a horizontal position, the right front flap 20 and the right rear flap 21 are folded down from top to bottom to a vertical position. Then, the fifth insertion fastener 49 on the right front side of the box is inserted into the fifth insertion hole 53, the seventh insertion fastener 51 is inserted into the seventh insertion hole 55, the sixth insertion fastener 50 on the right rear side of the box is inserted into the sixth insertion hole 54, and the eighth insertion fastener 52 is inserted into the eighth insertion hole 56.

[0046] As a further optimization of the above structure, the first, second, fifth, and sixth sockets are not direct through holes. When the box is unfolded or in its initial state, these four sockets are simply U-shaped cuts that penetrate the thickness of the front panel 2 or rear panel 3. After the box is folded, corresponding sockets will be formed at the left and right ends of the front panel 2 and rear panel 3, and the sockets will be connected in the front-to-back direction. Furthermore, below each socket, at the original U-shaped cut position, the protruding plate portion within the U-shaped outline forms four horizontal abutment plates 61. (See Appendix) Figure 4 With this design, the horizontal insertion holes facilitate the insertion and positioning of each insertion buckle when folded, because each insertion buckle needs to be bent inward to a roughly horizontal position before it can fit with the insertion hole. Therefore, each abutting protrusion 61 plays a role in supporting the insertion buckle in the vertical direction, ensuring the stability of the insertion structure.

[0047] On the other hand, in order to facilitate the loading and unloading of items from the box, an opening is made on the front panel 2. However, if the cut surface of the cutting board is directly used as the upper surface of the opening on the front panel 2, the aesthetics are poor. Moreover, in the folded box structure, the opening at the front panel 2 does not extend directly to the bottom plate 1, and there is still a certain height between them. In order to improve the strength of the raised part of the panel, in this embodiment, a foldable extension panel 22 is connected to the lower edge of the U-shaped opening on the front panel 2. The two sides of the extension panel 22 are disconnected from the two sides of the U-shaped opening. In other embodiments, when pressing the board, the two sides of the extension panel 22 can be connected to the two sides of the U-shaped opening by a tearable stitch. During the later folding and assembly, it can be manually torn and then the extension panel 22 can be folded towards the inside of the box until it fits against the front panel 2.

[0048] Furthermore, in the above structure, a left-hand insertion hole 57 and a right-hand insertion hole 58 are provided at the front edge of the base plate 1 near the edge of the front panel 2. Correspondingly, a ninth insertion block 59 and a tenth insertion block 60 are provided on the extension panel 22. After the box is assembled, the ninth insertion block 59 and the tenth insertion block 60 are vertically inserted into the left-hand insertion hole 57 and the right-hand insertion hole 58, respectively. After insertion, the lower end face of the ninth insertion block 59 and the tenth insertion block 60 is basically flush with the lower end face of the base plate 1. Further, in this structure, two fold lines are provided between the extension panel 22 and the edge of the lower side plate of the U-shaped opening. The gap between the two fold lines is consistent with the thickness of the front panel 2. In this way, the extension panel 22 is actually folded twice before being inserted and positioned with the base plate 1. The plate part between the two fold lines forms the bottom side plate of the front opening of the box, which is horizontal. This increases the structural strength of the front panel 2 of the box and also increases the aesthetic appearance of the opening.

[0049] In addition, after the left front wing 18, left rear wing 19, right front wing 20 and right rear wing 21 at both ends of the aforementioned left top plate 6 and right top plate 7 are folded and assembled, the left front wing 18 and right front wing 20 are respectively flush with the two sides of the U-shaped opening of the front panel 2, ensuring the overall aesthetics of the box. More specifically, in this structure, recessed limiting steps 23 are provided on the left and right sides of the front panel 2 away from the bottom plate 1 and on the left and right sides of the rear panel 3 away from the bottom plate 1. Corresponding clearance notches 24 are provided at the joints between the left front wing 18, left rear wing 19, right front wing 20 and right rear wing 21 and the left top plate 6 and right top plate 7. In this way, after the box is folded and assembled, the folded surface of each clearance notch 24 corresponds to each limiting step 23, ensuring that the left front wing 18, left rear wing 19, right front wing 20 and right rear wing 21 remain flat with each side after folding and can be stably limited to the left and right.

[0050] The storage box is made of relatively inexpensive and lightweight materials, such as, but not limited to, cardboard, plastics (e.g., corrugated plastic), combinations thereof, etc. Preferably, the storage box is formed from an initial sheet, more preferably from a single sheet of corrugated cardboard. The sheet can be formed in various ways as follows: Figure 1 The flat and folded assembled state shown is, for example, but not limited to, machine die-cutting, laser cutting, and manual cutting using tools such as scissors, knives, and saws.

[0051] The fold lines involved in the panel can be formed by pressing, stamping, die-cutting, or other methods to slightly weaken the line area so that the corresponding portion of the panel can be folded along the fold line, while providing material continuity between each pair of adjacent panels or between the panel portions connected at each corresponding fold line.
