A foldable cushioning inner tube

Abstract

This application provides a folding buffer tray, including a top surface with an opening for receiving, and two side surfaces, a connecting surface, a supporting surface, and a snap-fit ​​surface connected sequentially on opposite sides of the top surface. A supporting surface is located on the side of the side surface away from the connecting surface. The snap-fit ​​surface has a first notch, and the supporting surface has a second notch. When folding the cardboard, the top surface, the side surface on one side of the top surface, and the supporting surface form a "U"-shaped frame. The snap-fit ​​surfaces fold towards the bottom of the "U"-shaped frame, the two snap-fit ​​surfaces overlap, and the first notch of the snap-fit ​​surface interlocks with the second notch of the supporting surface. The "U"-shaped frames formed on the two opposite sides of the top surface together constitute a cavity for receiving the bottle. The folding and enclosing mechanism using the side surfaces, connecting surface, supporting surface, and snap-fit ​​surface allows for fast folding; the interlocking of the first notch of the snap-fit ​​surface with the second notch of the supporting surface improves the stability of the bottle. This folding buffer tray is simple to fold, uses less material, and reduces costs.

[0002] In the field of transportation packaging and storage of bottle products, in order to prevent the bottles from colliding and breaking, a buffer inner support structure is generally adopted, and the buffer inner support has buffer and shockproof functions.

[0003] Conventional inner supports are mostly made of foamed rubber or EPE, relying on the elastic deformation of the materials to absorb impact energy, but these two materials are costly and not environmentally friendly. There are also some inner supports with a folding buffer structure. Based on the principle of origami mechanics, a flat plate is folded at a specific angle through pre-creased lines to form a three-dimensional support frame to disperse external loads. However, the existing folding inner supports are complicated in folding and require too many creasing processes to be completed manually, which takes a long time. Utility Model Content

The "匚"-shaped frames formed on opposite sides of the top surface together constitute a cavity for accommodating a bottle.

[0007] Preferably, the side surface includes a first side part and a second side part that are connected to each other. The first side part is connected to the top surface, and opposite sides of the second side part are respectively connected to the connecting surface and the supporting surface.

[0008] Preferably, on the other opposite sides of the top surface, there are respectively provided extension surfaces, and the length of the extension surface is less than the length of the first side part.

[0009] Preferably, the length of the side of the supporting surface close to the connecting surface is half of the length of the side of the top surface close to the extension surface.

[0010] Preferably, the length of the second side part is less than the length of the first side part.

[0011] Preferably, a stepped engaging portion is provided on one side of the supporting surface close to the side vertical surface, and the stepped engaging portion abuts against the first side vertical portion and the second side vertical portion.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Reference Figures 1-7, showing a folding buffer inner support provided by an embodiment of the present application, which is cut and folded from a cardboard, and includes a top surface 1 provided with a receiving opening 11. On opposite sides of the top surface 1, there are respectively provided a side elevation 2, a connecting surface 3, a supporting surface 4, and a clamping surface 5 that are sequentially connected. On the side of the side elevation 2 away from the connecting surface 3, there is a supporting surface 6; wherein, the clamping surface 5 is provided with a first notch 51, and the supporting surface 6 is provided with a second notch 61;

[0030] When folding the cardboard, the top surface 1 and the side elevation 2 and the supporting surface 4 provided on one side of the top surface 1 enclose a "C" - shaped frame. The clamping surface 5 folds towards the bottom of the "C" - shaped frame, and the two clamping surfaces 5 overlap, and the first notch 51 of the clamping surface 5 is inserted into the second notch 61 of the supporting surface 6. The "C" - shaped frames formed on opposite sides of the top surface 1 together constitute a cavity for accommodating a bottle body.

[0031] In the embodiment of the present application, in view of the problems in the prior art that the inner support has a high cost, is not environmentally friendly, and has complicated folding and low efficiency, the present application provides a solution for an internal buffer structure with simple folding, specifically: it is cut and folded from a cardboard, and includes a top surface 1 provided with a receiving opening 11. On opposite sides of the top surface 1, there are respectively provided a side elevation 2, a connecting surface 3, a supporting surface 4, and a clamping surface 5 that are sequentially connected. On the side of the side elevation 2 away from the connecting surface 3, there is a supporting surface 6; wherein, the clamping surface 5 is provided with a first notch 51, and the supporting surface 6 is provided with a second notch 61; When folding the cardboard, the top surface 1 and the side elevation 2 and the supporting surface 4 provided on one side of the top surface 1 enclose a "C" - shaped frame. The clamping surface 5 folds towards the bottom of the "C" - shaped frame, and the two clamping surfaces 5 overlap, and the first notch 51 of the clamping surface 5 is inserted into the second notch 61 of the supporting surface 6. The "C" - shaped frames formed on opposite sides of the top surface 1 together constitute a cavity for accommodating a bottle body. By folding and enclosing through the side elevation 2, the connecting surface 3, the supporting surface 4, and the clamping surface 5, the problem of cumbersome folding steps is solved. The folding is simple and the folding speed is fast; by inserting the first notch 51 of the clamping surface 5 into the second notch 61 of the supporting surface 6, the stability of supporting the bottle body is ensured. The folding buffer inner support of the present application has simple folding, saves materials, and can effectively reduce costs.

[0032] Next, a folding buffer inner support in each exemplary embodiment of the present application will be further described.

[0033] As an example, the folding cushioning tray is made of a piece of cardboard cut and folded, preferably corrugated cardboard. Corrugated cardboard, also known as corrugated paperboard, is a multi-layered adhesive structure, consisting of at least one layer of corrugated core paper (commonly known as "corrugated sheet," "corrugated paper," "corrugated core," "corrugated base paper") and one layer of cardboard (also known as "boxboard"). It has high mechanical strength and can withstand collisions and drops during handling. The corrugated cardboard is preferably a 3- or 5-layer structure, with a thickness of 0.5-5mm, and the length and width are adjusted according to the size of the wine bottle.

[0034] In a specific implementation, refer to Figure 1 When the corrugated paper is unfolded, from left to right, it includes a first support surface 6, a first side facade 2, a top surface 1, a second side facade 2, and a second support surface 6; the side of the first side facade 2 opposite to the first support surface 6 is connected to the first connecting surface 3, the side of the first connecting surface 3 facing the top surface 1 is connected to the first supporting surface 4, and the side of the first supporting surface 4 away from the side facade 2 is connected to the first snap-fit ​​surface 5; the side of the second side facade 2 opposite to the second support surface 6 is connected to the second connecting surface 3, the side of the second connecting surface 3 facing the top surface 1 is connected to the second supporting surface 4, and the side of the second supporting surface 4 away from the side facade 2 is connected to the second snap-fit ​​surface 5.

[0035] In a specific implementation, refer to Figure 6 and Figure 7 The first supporting surface 4, the first side elevation 2, the top surface 1, the second side elevation 2 and the second supporting surface 4 form a frame with four sides. The first side elevation 2 and the second side elevation 2 are opposite to each other, and the first supporting surface 4 and the second supporting surface 4 are adjacent to each other and opposite to the top surface 1.

[0036] The connecting surface 3 is perpendicular to both the side facade 2 and the supporting surface 4. The snap-fit ​​surface 5 folds outward toward the frame and is perpendicular to the supporting surface 4. The supporting surface 6 is perpendicular to both the side facade 2 and the snap-fit ​​surface 5. The first notch 51 of the snap-fit ​​surface 5 and the second notch 61 of the supporting surface 6 are inserted into each other. During folding, the two snap-fit ​​surfaces 5 overlap and are fixed by being inserted through the notch of the supporting surface 6, thereby enhancing the structural strength.

[0037] Place the folded inner tray into the packaging box. The bottle enters through the receiving opening 11 on the top surface 1. The supporting surface 4 and the supporting surface 6 together support the bottle.

[0038] In this embodiment, the side facade 2 includes a first side facade 21 and a second side facade 22 that are connected to each other. The first side facade 21 is connected to the top surface 1, and the two opposite sides of the second side facade 22 are connected to the connecting surface 3 and the supporting surface 6, respectively.

[0039] In a specific implementation, both the first standing part 21 and the second standing part 22 are rectangular. The size of the second standing part 22 is smaller than that of the first standing part 21, and one side of the first standing part 21 and the second standing part 22 is flush. One side of the first standing part 21 away from the second standing part 22 is connected to the top surface 1. The two opposite sides of the second standing part 22 adjacent to the first standing part 21 are respectively connected to the support surface 6 on one side and the connection surface 3 on the other side.

[0040] In this embodiment, extension surfaces 7 are respectively provided on the other two opposite sides of the top surface 1, and the length of the extension surface 7 is smaller than the length of the first standing part 21.

[0041] As an example, the extension surface 7 is used for auxiliary limiting. The extension surface 7 can be in the shape of a rectangle, trapezoid, polygon, or the like.

[0042] In a specific implementation, the top surface 1 is hexagonal. Side surfaces 2 are respectively provided on the two opposite sides of the top surface 1, and rectangular extension surfaces 7 are provided on the two opposite sides of the top surface 1 with one side interval. After folding, the extension surface 7 folds down 90 degrees to perform auxiliary limiting on the middle side surface of the bottle body.

[0043] In this embodiment, the length of the side of the supporting surface 4 close to the connection surface 3 is half of the length of the side of the top surface 1 close to the extension surface 7.

[0044] It should be noted that when folding, two "匚"-shaped frames are formed on both sides. The combined length of the two supporting surfaces 4 is equal to the length of the top surface 1. The supporting surfaces 4 on both sides are spliced together at the bottom of the cavity, just covering the main stress area at the bottom of the bottle body, making the bottle body placed stably.

[0045] In this embodiment, the length of the second standing part 22 is smaller than the length of the first standing part 21.

[0046] It should be noted that the second standing part 22 is mainly used for connecting with the connection surface 3 and the support surface 6. The shorter length of the second standing part 22 can meet the connection requirements of the connection surface 3 and the support surface 6, making the overall structure more compact.

[0047] In this embodiment, a stepped engaging part 41 is provided on the side of the supporting surface 4 close to the side surface 2, and the stepped engaging part 41 abuts against the first standing part 21 and the second standing part 22.

[0048] It should be noted that the stepped engaging part 41 can enhance the connection stability between the side surface 2 and the supporting surface 4.

[0049] In one specific implementation, the length of the second side stand 22 is less than the length of the first side stand 21, and one side edge of the first side stand 21 and the second side stand 22 are flush. The stepped engaging part 41 abuts against the uneven corner of the first side stand 21 and the second side stand 22 to prevent relative sliding under force and improve the load-bearing capacity of the entire inner support structure.

[0050] In this embodiment, the connecting surface 3, the snap-fit ​​surface 5, and the supporting surface 6 are at the same height.

[0051] It should be noted that the connecting surface 3, the snap-fit ​​surface 5, and the supporting surface 6 are at the same height, so that these three parts are at the same plane or height after folding, and the force on the inner support is more even.

[0052] In this embodiment, the lengths of the edges connecting the connecting surfaces 3 and the supporting surfaces 4 are the same. This ensures that when folded, the lengths of the two connecting surfaces 3 are the same as the length of the side edge of the top surface 1 where the extension surface 7 is located, thus improving the support stability of the inner support.

[0053] The folding steps are as follows:

[0054] Fold the supporting surface 4 along the fold line of the side facade 2, so that both the supporting surface 4 and the connecting surface 3 are perpendicular to the side facade 2. Figure 2 As shown. Fold the snap-fit ​​surface 5 along the fold line of the supporting surface 4, so that the snap-fit ​​surface 5 is perpendicular to the supporting surface 4 and parallel to the side facade 2, as shown. Figure 3 As shown. Fold the supporting surface 4 along the fold line of the connecting surface 3, so that the supporting surface 4 and the snap-fit ​​surface 5 are perpendicular to the connecting surface 3, as shown. Figure 4 As shown. Fold the supporting surface 6 along the fold line of the second side elevation 22 of the side elevation 2, so that the supporting surface 6 is perpendicular to the side elevation 2. Then fold the side elevation 2 along the fold line of the top surface 1, so that the side elevation 2 is perpendicular to the top surface 1. The supporting surface 4 is opposite to the top surface 1, as shown. Figure 5 As shown. Both sides of the top surface 1 are folded as described above. Finally, the extension surface 7 is folded along the fold line of the top surface 1, making the extension surface 7 perpendicular to the top surface 1, resulting in the folded inner cushion support, as shown. Figure 6 and Figure 7 As shown.
