Abstract
Description
Technical Field
[0001] This application belongs to the field of packaging technology, specifically relating to a paper card, packaging liner, and packaging component. Background Technology
[0002] Due to shape limitations, products generally cannot fit perfectly into packaging boxes. Therefore, in order to protect products during assembly, transportation, and sales, it is usually necessary to add linings to the packaging boxes to cushion the impact of external stress caused by shocks, collisions, drops, etc. during the movement process.
[0003] Existing packaging liners are mostly made of foam or pearl cotton. While they effectively protect products, the production of foam or pearl cotton requires molding, leading to higher costs. Furthermore, these materials take up considerable space, making them inconvenient for storage and transportation. Additionally, foam materials are generally made of EPE (polyethylene) and EPS (polystyrene), which are non-degradable and environmentally unfriendly. Utility Model Content

[0024] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0026] The following description, in conjunction with the accompanying drawings, details the paper cards, packaging liners, and packaging components provided in this application through specific embodiments and application scenarios.
[0027] refer to Figures 1-5This application provides a foldable paper card that can be folded and assembled into... Figure 6 The packaging liner 1 is shown. In this way, when product packaging is not required, the packaging liner 1 can be unfolded and flattened into a board structure, which greatly reduces the transportation and storage space occupied by the packaging liner and reduces the storage or transportation cost of the packaging liner 1.
[0028] The paper card may include four first rectangular plates 101, 102, 103, and 104, which are arranged and connected sequentially along their width. A connecting portion 800 is provided on the side of the outermost first rectangular plate 101 facing away from the other first rectangular plates 102, 103, and 104. The first rectangular plates 101, 102, 103, and 104 are bent and closed along their connecting points, and the connecting portion 800 and the first connecting plate 104 on the other side are connected by adhesive, nailing, or other methods to form a cylindrical structural component. Each first rectangular plate 101, 102, 103, and 104 constitutes one side of the cylindrical structural component. In this embodiment, the first rectangular plates 101, 102, 103, and 104 have the same shape; therefore, the cross-section of the cylindrical structural component is square. Depending on the shape of the packaged product, in other embodiments, the first rectangular plates 101, 102, 103, and 104 can also have different widths. For example, two first rectangular plates 101 and 103 may be narrower, while the other two first rectangular plates 102 and 104 may be wider, thus forming a cylindrical structure with a rectangular cross-section. Furthermore, the number of first rectangular plates can vary, but is at least three. Since packaging boxes are mostly square, generally four first rectangular plates are used. However, when packaging triangular products, only three first rectangular plates may be used to fit the product. Similarly, when packaging polyhedral irregularly shaped products, more first rectangular plates can be used to fit the product's outer contour; this application does not limit this. In this case, the cross-sectional profile of the cylindrical structure along its axial direction is polygonal.
[0029] First rectangular plates 101, 102, 103, and 104 are respectively connected to first connecting plates 301, 302, 303, and 304 and second connecting plates 401, 402, 403, and 404 on a pair of sides along the axial direction of the cylindrical structural member. The first connecting plates 301, 302, 303, and 304 connect the first rectangular plates 101, 102, 103, and 104 and the second rectangular plates 201, 202, 203, and 204. Third connecting plates 501, 502, 503, and 504 are also provided on the opposite sides of the second rectangular plates 201, 202, 203, and 204. The heights of the second rectangular plates 201, 202, 203, and 204 are the same as those of the first rectangular plates 101, 102, 103, and 104 to which they are connected. The widths of the second rectangular plates 201, 202, 203, and 204 are smaller than the widths of the first rectangular plates 101, 102, 103, and 104 to which they are connected.
[0030] The packaging liner serves as a cushioning element to protect the product; therefore, cushioning structures are formed on each side of the cylindrical structure. Each side's cushioning structure is constructed from folded paper cards. The cushioning structure consists of a first rectangular plate 101, 102, 103, 104 and a second rectangular plate 201, 202, 203, 204 spaced apart to form a cushioning space. One side of the first rectangular plate 101, 102, 103, 104 and the second rectangular plate 201, 202, 203, 204 are connected by first connecting plates 301, 302, 303, 304. The other side overlaps with the second connecting plates 401, 402, 403, 404 (connected to the first rectangular plate 101, 102, 103, 104) and the third connecting plates 501, 502, 503, 504 (connected to the second rectangular plate 201). The first rectangular plates 101, 102, 103, 104, the first connecting plates 301, 302, 303, 304, the second rectangular plates 201, 202, 203, 204, and the second connecting plates 401, 402, 403, 404 together form a buffer space. To form this buffer space, the first rectangular plates 101, 102, 103, 104 and the second rectangular plates 201, 202, 203, 204 are of equal height. In this embodiment, each of the first rectangular plates 101, 102, 103, 104 has the same height, therefore each of the second rectangular plates 201, 202, 203, 204 also has the same height. In other preferred embodiments, due to the different shapes of the packaged products, the heights of the first rectangular plates may not be the same; in such cases, the second rectangular plates only need to have the same height as the first rectangular plates they are connected to, in order to form a stable buffer space.
[0031] The second connecting plate 401 and the third connecting plate 501 can be connected by means of adhesive, nailing, etc. In this embodiment, the connection between the second connecting plates 401, 402, 403, 404 and the first rectangular plates 101, 102, 103, 104 is provided with slits 701, 702, 703, 704, and the third connecting plate 501 is provided with buckle parts 601, 602, 603, 604 on the side opposite to the second rectangular plates 201, 202, 203, 204. When the second rectangular plates 201, 202, 203, 204 bend towards the first rectangular plates 101, 102, 103, 104, the third connecting plates 501, 502, 503, 504 overlap with the second connecting plates 401, 402, 403, 404, and the snap-fit parts 601, 602, 603, 604 are inserted into the slits 701, 702, 703, 704 to achieve connection. In other preferred embodiments, the snap-fit parts 601, 602, 603, 604 and the slits 701, 702, 703, 704 can also be interchanged. The buckle parts 601, 602, 603, and 604 are located on the side of the second connecting plates 401, 402, 403, and 404 away from the first rectangular plates 101, 102, 103, and 104, and the slits 701, 702, 703, and 704 are located at the connection between the third connecting plates 501, 502, 503, and 504 and the second rectangular plates 201, 202, 203, and 204.
[0032] The folding and forming process of the inner packaging liner is as follows: Figure 2-5 As shown. Figure 2 The second rectangular plates 201, 202, 203, and 204 are bent toward the first rectangular plates 101, 102, 103, and 104, forming a buffer space between the second rectangular plates 201, 202, 203, and 204 and the first rectangular plates 101, 102, 103, and 104. Figure 3 As shown. Each of the first rectangular plates 101, 102, 103, and 104 is bent toward the adjacent first rectangular plates 101, 102, 103, and 104, forming an enclosure as shown. Figure 4The cylindrical structural component is shown. First rectangular plates 101, 102, 103, and 104 form the outer contour of the cylindrical structural component, while second rectangular plates 201, 202, 203, and 204 form the inner contour. Therefore, it can be assumed that the second rectangular plates 201, 202, 203, and 204 bend towards the inside of the cylindrical structural component. Since the first rectangular plates 101, 102, 103, and 104 and the second rectangular plates 201, 202, 203, and 204 are spaced apart to form a certain thickness, the inner surface of the cylindrical structural component will be smaller than the outer surface. Therefore, the width of the second rectangular plates 201, 202, 203, and 204 should be smaller than the width of the first rectangular plates 101, 102, 103, and 104. Meanwhile, the first connecting plates 301, 302, 303, and 304 are isosceles trapezoids, with their base sides equal in width to the first rectangular plates 101, 102, 103, and 104, and their top sides equal in width to the second rectangular plates 201, 202, 203, and 204. In this embodiment, the packaging liner 1 has a square structure, including four first rectangular plates 101, 102, 103, and 104. Therefore, the base angle of the isosceles trapezoid is 45°, and after folding, its waist fits perfectly with the waist of the adjacent isosceles trapezoid. On the other side, as... Figure 4 The second connecting plates 401, 402, 403, and 404 are first bent inwards towards the cylindrical structure, with partial overlap at the corners. Then, the third connecting plates 501, 502, 503, and 504 are bent towards the second connecting plates 401, 402, 403, and 404, and the snap fasteners 601, 602, 603, and 604 are inserted into the slits 701, 702, 703, and 704, as shown. Figure 6 The inner packaging liner 1 shown is now complete.
[0033] The paper card provided in this application has a flat structure and is formed by cutting single-sheet materials such as single-layer board or corrugated board. To facilitate subsequent folding, crease lines are provided at the joints between the first rectangular plates 101, 102, 103, 104 and the second rectangular plates 201, 202, 203, 204, the first connecting plates 301, 302, 303, 304, the second connecting plates 401, 402, 403, 404, and the third connecting plates 501, 502, 503, 504. The packaging liner formed by folding the paper card is more environmentally friendly than packaging liners made of materials such as plastic or foam, and can be reused.
[0034] The packaging liner 1 provided in this embodiment is used to package the lighting product 2, such as... Figure 7 As shown, the lighting product 2 is a downlight with a square face ring, and the inner packaging liner 1 fits perfectly with the outer contour of the face ring. In other preferred embodiments, the inner packaging liner 1 can also be used to package products with a circular outer contour, and this application does not limit this to that.
[0035] Based on the packaging liner provided in the embodiments of this application, the embodiments of this application also provide a packaging component, such as... Figure 8 The packaging assembly shown may include a box body 2 and a packaging liner 1 as described in the above embodiment, in which the lighting product 2 is placed. The inner side of the packaging liner 1 wraps around the lighting product 2, and the outer side is fitted against the inner wall of the box body 3, which can improve the overall pressure resistance of the box body 3.
[0036] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
