Description

Technical Field

[0001] This utility model relates to a protective inner lining structure and a pump head product packaging box, belonging to the field of product packaging technology. Background Technology

[0002] Cosmetics, especially high-end skincare products in glass or hard plastic bottles equipped with pumps, are highly susceptible to damage during transportation due to vibration, collisions, or drops. The damage primarily manifests in three ways: first, the bottle breaks under pressure on the side; second, the bottom cracks due to direct impact; and third, the protruding pump head is crushed or broken.

[0003] Current technologies often use molded pulp liners or expanded polystyrene (EPS) as cushioning. Molded pulp liners have limited cushioning performance and often provide insufficient protection for protruding parts such as pump heads; expanded polystyrene is not environmentally friendly, difficult to recycle, and expensive. In addition, some corrugated cardboard liners have simple structures, usually only a single layer, with insufficient compressive strength of the side walls, and cannot provide adequate protection for fragile glass bottles.

[0004] It is evident that, in order to achieve comprehensive protection for cosmetic bottles and pump heads, there is an urgent need for a protective inner lining structure and a pump head product packaging box. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a protective inner liner structure and pump head product packaging box to solve the technical problem that the existing cosmetic inner liner does not provide sufficient protection for the sides, bottom and pump head of the bottle.

[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution: In a first aspect, this utility model provides a protective liner structure, comprising: The inner liner body has a receiving cavity for accommodating the product. A raised structure is provided at the bottom of the accommodating cavity; A receiving portion, disposed at the top of the receiving cavity, for receiving the pump head of the product; and, A buffer layer is disposed on at least one sidewall of the accommodating cavity.

[0007] Furthermore, the inner lining body includes: The first side plate, second side plate, third side plate, and fourth side plate can be folded and connected sequentially by the crease lines; The first top plate and the first bottom plate are foldably connected to the upper and lower sides of the second side plate via indentation lines; and... The second top plate and the second bottom plate can be folded and connected to the upper and lower sides of the fourth side plate via embossing lines.

[0008] Furthermore, the first top plate has a through hole for the pump head to pass through, and after the inner liner body is folded, the space formed between the first top plate and the second top plate is a receiving part.

[0009] Furthermore, the raised structure is disposed on the first base plate or the second base plate.

[0010] Furthermore, the buffer layer is composed of multiple layers of buffer material stacked together.

[0011] Furthermore, the cushioning material is corrugated board.

[0012] Furthermore, a buffer layer is provided at each side wall of the accommodating cavity.

[0013] Furthermore, the buffer layer comprises three layers of corrugated board stacked together; Each of the three layers of corrugated board includes four sub-side panels connected in sequence by indentation lines. The four sub-side panels are folded together to form a rectangular frame. The three rectangular frames are stacked together to form the buffer layer.

[0014] Furthermore, one of the sub-side panels of the innermost corrugated board is integrally connected to the side of the first bottom plate via an indentation line, and this sub-side panel is arranged opposite to the second side panel.

[0015] Secondly, this utility model provides a pump head product packaging box, including the protective inner liner structure described in the first aspect.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: The protective liner structure provided by this utility model elevates the product through a raised structure, forming a buffer space between its bottom and the outer bottom surface of the liner body. This prevents the bottom of the product from being directly subjected to force when the packaging is subjected to vertical impact. A dedicated space is provided for the pump head through a receiving section, preventing damage from compression during transportation and stacking. The buffer layer significantly enhances the planar compressive strength and cushioning performance of the liner sidewalls, effectively absorbing and dispersing impact and compression energy from the sides, thus providing strong protection for fragile glass or hard plastic bottles. The pump head product packaging box provided by this utility model, by adapting to the above-mentioned protective inner lining structure, provides all-round, multi-layered cushioning protection for the bottom, sides and top of the contents inside the packaging box, which can effectively ensure the contents are safe and undamaged in complex logistics environments.

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0020] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0022] like Figure 1 As shown, this embodiment provides a protective liner structure, including: The inner liner body 1 has a receiving cavity 2 for accommodating the product. Elevation structure 3, wherein the elevation structure 3 is disposed at the bottom of the accommodating cavity 2; Receiving portion 4, disposed at the top of receiving cavity 2, for receiving the pump head of the product; and, A buffer layer 5 is disposed on at least one side wall of the accommodating cavity 2.

[0023] In the above technical solution, the inner liner body 1 has a cuboid structure, and a receiving cavity 2 for accommodating the product bottle is defined within the inner liner body 1. The elevating structure 3 can be a protruding structure formed by cutting and folding the base plate material itself; or it can be an independent component fixed to the bottom by molding, bonding, or snap-fitting, such as a piece of foam or plastic pad. Its core function is to elevate the product placed in the receiving cavity 2, so that its bottom is formed with the outer bottom surface of the inner liner body 1, thereby preventing the bottom of the product from being directly subjected to force when the packaging is subjected to vertical impact.

[0024] The receiving section 4 can be a downwardly recessed groove or a hole penetrating the top of the liner. Its function is specifically to receive and allow space for the protruding pump head on the bottle, providing dedicated space for the pump head and preventing it from being damaged by compression during transportation and stacking.

[0025] By setting a buffer layer 5 inside the accommodating cavity 2, the planar compressive strength and buffering performance of the inner liner sidewall are significantly enhanced, which can effectively absorb and disperse the impact and extrusion energy from the side, thus providing strong protection for the fragile glass or hard plastic bottle body. Example 2

[0026] like Figure 1 and Figure 2 As shown, the protective liner structure provided in this embodiment differs from the protective liner structure provided in Embodiment 1 in that: like Figure 1 and Figure 2 As shown, in this embodiment, the inner lining body 1 is formed by dividing and connecting a single piece of cardboard through pre-made crease lines. The inner lining body 1 includes: The first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 can be folded and connected in sequence through the indentation lines. After being folded, these four side plates together form the four side walls of the accommodating cavity 2. The first top plate 15 and the first bottom plate 16 are foldably connected to the upper and lower sides of the second side plate 12 via indentation lines; and... The second top plate 17 and the second bottom plate 18 are folded and connected to the upper and lower sides of the fourth side plate 14 via embossing lines.

[0027] The first top plate 15 has a through hole 19 for the pump head to pass through. After the inner liner body 1 is folded, the space formed between the first top plate 15 and the second top plate 17 is the receiving part 4. The shape and size of the through hole 19 can be adjusted according to the size of the specific pump head, such as round, square or irregular shape.

[0028] The raised structure 3 is disposed on the first base plate 16 or the second base plate 18. In this embodiment, as shown... Figure 1 and Figure 2 As shown, the raised structure 3 is a boss formed by cutting and folding inwards a portion of the material on the second base plate 18 and the fourth side plate 14. This structure requires no additional parts and achieves integral molding with the body.

[0029] The buffer layer 5 is composed of multiple layers of buffer materials. By setting up a multi-layer buffer structure, the planar compressive strength and buffering performance of the inner liner sidewall are significantly enhanced, which can effectively absorb and disperse the impact and compression energy from the side, thereby providing strong protection for fragile glass or hard plastic bottles.

[0030] The cushioning material is corrugated board.

[0031] A buffer layer 5 is provided on each side wall of the accommodating cavity 2.

[0032] The buffer layer 5 comprises three layers of corrugated board stacked together. Each of the three corrugated sheets comprises four sub-side panels connected sequentially by indentation lines. These four sub-side panels, when folded, enclose a rectangular frame. The three rectangular frames are stacked together to form the buffer layer 5. These four sub-side panels can be folded along the indentation lines and fixed with adhesive to form a hollow rectangular frame, collectively constituting a robust composite buffer layer 5. Compared to simple flat sheet stacking, this layer offers higher structural stability and resistance to deformation.

[0033] One of the sub-side panels of the innermost corrugated plate is integrally connected to the side of the first base plate 16 via an indentation line, and this sub-side panel is positioned opposite the second side panel 12. This integrated design eliminates assembly gaps between components, greatly improving the rigidity and protective performance of the overall structure. Example 3

[0034] like Figure 3 and Figure 4 As shown, this embodiment provides a pump head product packaging box, which includes a conventional outer box A and a protective inner liner structure as described in Embodiment 1 or Embodiment 2 placed inside the outer box A.

[0035] In use, place the cosmetic bottle into the receiving cavity 2 of the protective liner structure, with its bottom resting on the raised structure 3, and the pump head passing through the through-hole 19 at the top. Then, pack the entire liner containing the product into the outer box A and seal the box. This packaging box provides all-around, multi-layered cushioning protection for the bottom, sides, and top through the liner, effectively ensuring the contents remain safe and undamaged in complex logistics environments.

[0036] Outer carton A is also made from a single piece of cardboard, divided and connected by pre-made crease lines. See the unfolded diagram of outer carton A. Figure 4 This one-piece molding structure facilitates later recycling and is in line with environmental protection principles.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
