[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0045] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0046] At present, the packaging boxes of bottled products (such as beauty serums, etc.) are usually designed with liners, which are used to fix and support the products in the box. The traditional liner includes a plurality of inserts, which are plugged into each other in a tic-tac-toe arrangement, and the liner can be folded or unfolded. When the liner is placed in the packaging box, it is unfolded to form a plurality of receiving slots, each of which can be used to place the bottled product. However, the structure of this liner is not tight enough, and the stiffness (i.e., the ability of an object to resist its deformation) is not strong. After unfolding, it is easy to return to the folded state, which is not conducive to the safe transportation of the product.

[0047] Based on the defects of the traditional liner 100, the utility model proposes a liner 100 for a packaging box to improve the structural tightness and stiffness, so that it is not easy to fold back and ensure the safe transportation of the product. Figure 1 and Figure 2 The liner 100 includes: a frame 110, at least one first plug-in sheet 121 and at least one second plug-in sheet 122; at least one first plug-in sheet 121 is plug-fitted with the frame along the height direction of the frame 110; at least one second plug-in sheet 122 is plug-fitted with at least one first plug-in sheet 121 along the height direction of the frame 110; wherein the frame 110, at least one first plug-in sheet 121 and at least one second plug-in sheet 122 cooperate to form a plurality of receiving grooves R for placing products.

[0048] The outer shape of the frame 110 can be various, for example, the frame can be square, circular, triangular or other shapes, which is not limited in this embodiment. The first plug-in sheet 121 and the second plug-in sheet 122 are sheet structures, and the plug-in structure composed of the first plug-in sheet 121 and the second plug-in sheet 122 is located in the frame 110, and the frame 110 is located at the periphery of the plug-in structure composed of the first plug-in sheet 121 and the second plug-in sheet 122. The first plug-in sheet 121 is along the height direction of the frame 110, and the two ends of the first plug-in sheet 121 are respectively plugged with the frame 110. Further, the second plug-in sheet 122 is along the height direction of the frame 110, and the second plug-in sheet 122 is plugged with each first plug-in sheet 121. It can be understood that the angle between the first plug-in sheet 121 and the second plug-in sheet 122 can be selected as an acute angle, a right angle or an obtuse angle as needed.

[0049] There is at least one first plug 121 and at least one second plug 122, respectively. The number of the first plug 121 and the second plug 122 can be set according to actual conditions, and this embodiment does not limit this.

The four first plug-ins 121 are plugged into the frame 110, and one second plug-in sheet 122 is plugged into the four first plug-ins 121. The frame 110, the four first plug-ins 121, and the one second plug-in sheet 122 cooperate to form ten receiving slots R, which can be used to place ten products.

[0050] During assembly, at least one first plug-in sheet 121 may be inserted into the frame 110 first, and then at least one second plug-in sheet 122 may be inserted into the at least one first plug-in sheet 121 to complete the assembly. Alternatively, at least one second plug-in sheet 122 may be inserted into the at least one first plug-in sheet 121 first, and then at least one first plug-in sheet 121 that is inserted and matched with the at least one second plug-in sheet 122 may be inserted into the frame 110 as a whole to complete the assembly. The user may select any of the above two assembly methods, and there is no limitation on this.

[0051] Optionally, at least one of the frame 110, the first insert 121 and the second insert 122 is made of paper material. As a preferred solution, the frame 110, the first insert 121 and the second insert 122 are all made of paper material.
