Description

Technical Field

[0001] This application relates to the field of packaging paper, and in particular to a folding cushioning insert. Background Technology

[0002] In the field of transportation packaging and storage of bottled products, a cushioning inner tray structure is commonly used to prevent bottles from being damaged by collision. The cushioning inner tray has cushioning and shockproof functions.

[0003] Conventional inner supports are mostly made of expanded polystyrene foam or pearl cotton, relying on the elastic deformation of the materials to absorb impact energy. However, these two materials are expensive and not environmentally friendly. Some inner supports use a folding cushioning structure, based on the principles of origami mechanics. Flat panels are folded at specific angles through pre-crease lines to form a three-dimensional support frame to distribute external loads. However, existing folding inner supports are complex to fold, requiring too many manual crease processes, which is time-consuming. Utility Model Content

The side of the second inner lining frame that is away from the first inner lining frame extends to form a support surface. The support surface is provided with a first notch, and the inner lining surfaces of the two sides are connected, with a second notch at the connection point.

[0007] When the cardboard is folded, the supporting surface, the inner lining surface, the top surface, and the side facade of the side portion form a side frame.

[0010] Preferably, the supporting surface extends to one side of the second inner lining frame, and a stepped engaging portion is provided on the side of the supporting surface away from the second inner lining frame.

[0011] Preferably, the stepped engagement portion includes a first engagement edge and a second engagement edge that are perpendicular to each other;

[0012] When the card is folded, the first edge of the card abuts against the connection portion of the support surface, and the second edge of the card abuts against the crease.

[0013] Preferably, the length of the folded portion is greater than the width of the supporting surface.

[0014] Preferably, the second notch is located between the two inner lining surfaces.

[0030] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. 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 without inventive effort are within the scope of protection of this application.

[0031] The inventors, through analysis of existing technologies, discovered that the production processes of expanded polystyrene (EPS) and pearl cotton involve the use of petrochemical raw materials, whose prices are greatly affected by fluctuations in international oil prices. EPS takes over 200 years to naturally degrade, and pearl cotton takes over 50 years. Furthermore, the production processes pollute the environment; incineration produces highly toxic substances such as dioxins, making them environmentally unfriendly. Existing folding structures involve numerous folding actions, requiring extensive folding and assembly, resulting in low folding efficiency. Moreover, because existing folding structures are typically composed of multiple folded panels connected by creases, their structural mechanics are weak.

[0032] It should be noted that, in any embodiment of this application, the folding buffer inner support can be used to support a cylindrical bottle, such as a wine bottle or a beverage bottle.

[0033] Reference Figures 1-5 This illustration shows a folding buffer tray provided in an embodiment of the present application, which is cut and folded from a piece of cardboard and includes two mirror-symmetrical sides. The sides include a support surface 1, a side facade 2, a top surface 3, and an inner lining surface 4 connected in sequence.

[0034] The top surface 3 is provided with a first inner lining frame 31, and the inner lining surface 4 is provided with a second inner lining frame 41 that communicates with the first inner lining frame 31. The side of the second inner lining frame 41 that is away from the first inner lining frame 31 extends to form a supporting surface 5. The supporting surface 1 is provided with a first notch 13, and the two side inner lining surfaces 4 are connected, and a second notch 6 is provided at the connection.

[0035] When the cardboard is folded, the supporting surface 5, the inner lining surface 4, the top surface 3, and the side vertical surface 2 of the side portion form a side frame. The two inner lining surfaces 4 are folded together along the connection. The supporting surface 1 is located below the supporting surface 5, and the first notch 13 of the supporting surface 1 is inserted into the second notch 6 at the connection. The first inner lining frame 31 and the second inner lining frame 41 of the two side frames together constitute a cavity for accommodating the bottle.

[0036] In the embodiment of the present application, the problem of complicated folding steps is solved by folding and enclosing the supporting surface 5, the inner lining surfaces 4, the top surfaces 3 and the side elevations 2, which enables simple folding and fast folding speed; the first notch 13 on the supporting surface 1 is inserted and connected with the second notch 6 at the connecting portion, so as to ensure the supporting stability for the bottle body. The folding buffer inner tray of the present application is simple to fold, saves material, and can effectively reduce the cost.

[0037] Hereinafter, a folding buffer inner tray according to exemplary embodiments of the present application will be further described.

[0038] As an example, the folding buffer inner tray is formed by cutting and folding a piece of cardboard, preferably corrugated paper. Corrugated paperboard, also known as corrugated board, is a multi-layer adhesive assembly, which is composed of at least one layer of wave-shaped core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of paperboard (also known as "boxboard", "box paperboard"). It has high mechanical strength and can withstand collision and falling during transportation. The corrugated paper is preferably of 3-layer or 5-layer structure, has a thickness of 0.5-5mm, and the length and width are adaptively adjusted according to the size of the wine bottle.

[0039] In a specific implementation, with reference to Figure 1 , when the corrugated paper is unfolded, it comprises, from left to right, a first supporting surface 1, a first side elevation 2, a first top surface 3, a first inner lining surface 4, a second inner lining surface 4, a second top surface 3, a second side elevation 2 and a second supporting surface 1. The first top surface 3 is provided with a first inner lining frame 31, the first inner lining surface 4 is provided with a second inner lining frame 41 communicated with the first inner lining frame 31, and a side of the second inner lining frame 41 away from the first inner lining frame 31 extends to form a first supporting surface 5. The second top surface 3 is provided with a third inner lining frame, the second inner lining surface 4 is provided with a fourth inner lining frame communicated with the third inner lining frame, and a side of the fourth inner lining frame away from the third inner lining frame extends to form a second supporting surface 5.

[0040] In a specific implementation, with reference to Figures 3-5 , when the corrugated paper is folded, the supporting surface 5, the inner lining surface 4, the top surface 3 and the side elevation 2 on each side are enclosed to form a side frame, and the two inner lining surfaces 4 are folded and combined along the connecting portion to form an inverted "日"-shaped inner tray. It can be understood that at this time, the top surfaces 3 of the two side frames are parallel and attached to each other, the two inner lining surfaces 4 overlap, the two side elevations 2 are oppositely arranged and located on the outermost side of the inner tray, and the two supporting surfaces 5 are parallel and attached to each other and parallel to the top surfaces 3, so that the inner lining frames on the top surfaces 3 of the two side frames and the inner lining frames on the inner lining surfaces 4 together form an accommodating cavity for accommodating the bottle body.

[0041] In this embodiment, the supporting surface 1 includes a connecting part 11 and a folding part 12. The connecting part 11 is connected to the side surface 2. A crease is provided between the connecting part 11 and the folding part 12. The first notch 13 is provided in the folding part 12.

[0042] When the folded portion 12 is folded along the crease, the folded portion 12 is perpendicular to the supporting surface 5, and the first notch 13 is inserted into the second notch 6.

[0043] As an example, the support surface 1 is located on the side of the side facade 2 away from the top surface 3, and the extended surface of the support surface 1 may at least partially overlap with the supporting surface 5.

[0044] In a specific implementation, refer to Figure 2 and Figure 5 The connecting part 11 of the support surface 1 is connected to the side edge of the side facade 2 away from the top surface 3. The folding part 12 of the support surface 1 is provided with a first notch 13. The extended surface of the folding part 12 partially overlaps with the supporting surface 5, and the extended surface of the first notch 13 overlaps with the supporting surface 5. When the corrugated paper is folded, the folding part 12 is perpendicular to the connecting part 11, the folding part 12 is perpendicular to the supporting surface 5, the supporting surface 5 is perpendicular to the connecting part 11, and the first notch 13 of the folding part 12 is inserted into the second notch 6.

[0045] In this embodiment, the length of the folded portion 12 is greater than the width of the supporting surface 5.

[0046] It should be noted that, as Figure 1 As shown, the width is the length of the horizontal side of each fold, and the length is the length of the vertical side. Taking the left side as an example, the length of the fold 12 refers to the length of the left side of the fold 12; the width of the supporting surface 5 refers to the length of the top or bottom edge of the supporting surface 5. Understandably, the length of the fold 12 must be greater than the width of the supporting surface 5 so that the first notch 13 of the fold 12 can be inserted into the second notch 6.

[0047] In this embodiment, the supporting surface 5 extends to one side of the second inner lining frame 41, and a stepped engaging portion is provided on the side of the supporting surface 5 away from the second inner lining frame 41.

[0048] As an example, the support surface 5 extends from the side of the second inner frame 41 away from the first inner frame 31. The size of the support surface 5 is less than or equal to the size of the second inner frame 41, and the width of the support surface 5 is the same as the width of the top surface 3, that is, the width of the second inner frame 41 is greater than or equal to the width of the top surface 3.

[0049] In one specific implementation, the top surface 3 and the inner lining surface 4 have equal lengths, and the width of the second inner lining frame 41 is greater than the width of the top surface 3. Since the supporting surface 5 extends from the second inner lining frame 41 of the inner lining surface 4, the length of the supporting surface 5 is less than the length of the top surface. A stepped engaging portion is provided on the side of the supporting surface 5 away from the second inner lining frame 41.

[0050] In this embodiment, the stepped engagement portion includes a first engagement edge and a second engagement edge that are perpendicular to each other;

[0051] When the card is folded, the first edge of the card abuts against the connecting part 11 of the support surface 1, and the second edge of the card abuts against the crease.

[0052] In a specific implementation, refer to Figure 2 When folded, the first locking edge is located inside the side frame, abutting against the connection between the first locking edge and the connecting part 11 and the side facade 2, while the second locking edge abuts against the crease of the supporting surface 1. The supporting surface 5 also has a third locking edge, which is perpendicular to the second locking edge. The first, second, and third locking edges form a "Z"-shaped edge, and when folded, the third locking edge abuts against the side facade 2. The stepped locking part can enhance the stability of the structure.

[0053] In this embodiment, the second notch 6 is located between the two inner lining surfaces 4.

[0054] Understandably, placing the second notch 6 between the inner lining surfaces 4 allows the support surface 1 to be positioned below the supporting surface 5 through the first notch 13 and the second notch 6, thereby enhancing the stability of the structure.

[0055] As an example, one or two notches can be provided between the inner lining surfaces 4. When a second notch 6 is provided, the width of the second notch 6 is greater than the thickness of the cardboard so that the folded part 12 can be inserted into the second notch 6. When two second notches 6 are provided, the width of the second notch 6 is greater than twice the thickness of the cardboard. Figure 1 As shown, the width of the second notch 6 refers to the radial width.

[0056] In one specific implementation, a second notch 6 is provided at the connection between the two inner lining surfaces 4, and the width of the second notch 6 is slightly greater than twice the thickness of the cardboard.

[0057] In this embodiment, both the first inner lining frame 31 and the second inner lining frame 41 are hollow structures;

[0058] When the card is folded, the first inner liner frame 31 and the second inner liner frame 41 connect to form an "L" shaped channel.

[0059] As an example, when the card is unfolded, the first inner liner frame 31 and the second inner liner frame 41 connect to form a rectangular frame. When the card is folded, the first inner liner frame 31 and the second inner liner frame 41 on the two sides connect to form an "L"-shaped channel.

[0060] In this embodiment, the length of the side facade 2 is the same as the length of the inner lining surface 4.

[0061] In one specific implementation, the dimensions of the side facade 2 are the same as the dimensions of the inner lining facade 4.

[0062] In one specific implementation, the length of the side facade 2 is the same as the length of the inner lining 4, and the width of the side facade 2 is less than the width of the inner lining 4.

[0063] When folded, as Figure 2 As shown, the supporting surface 1, side facade 2, top surface 3, and inner lining surface 4 are folded along the creases respectively. The two inner lining surfaces 4 are folded together along the joint and overlapped. Figure 2 In the direction of the arrow, the two side support surfaces 5 are pressed down as support baffles for the wine bottle. The protrusion of the stepped engagement part of the support surface 5 is engaged on the side of the side surface 2 that is not connected to the connection part 11 of the support surface 1. The first notch 13 of the two support surfaces 1 are engaged at the second notch 6.

[0064] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
