[0018] An embodiment of the present application provides an insulating packaging box lining, which is used to solve the technical problem that the temperature locking method of the existing packaging box not only takes up a large space and increases the weight of the packaging box, but also causes condensation of moisture in the packaging box when ice cubes or ice bags melt, which can easily cause the packaging box and the packaged products to become damp or require additional partition structures, resulting in high packaging costs.

[0019] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] See also Figures 1 to 3An embodiment of the present application provides a thermally insulating packaging box lining, comprising a lining body 10 made of a thermally insulating material, the lining body 10 being provided with a plurality of limiting grooves 100, and a partition wall 200 made of a thermally insulating material extending horizontally from one side of the lining body 10, the partition wall 200 being used to form a accommodating groove 300 for fixing a cold source between the lining body 10 and the inner wall of the packaging box, the accommodating groove 300 being provided with a cold conduction port 310, the interior of the lining body 10 being provided with a cold conduction channel 400, the cold conduction port 310 connecting the accommodating groove 300 with the cold conduction channel 400; the cold conduction channel 400 being provided with a connecting port 500 at the bottom thereof being connected with the limiting groove 100.

[0021] Specifically, the lining body 10 is adapted to the shape of the inner cavity of the packaging box, and a plurality of limiting grooves 100 for limiting the packaged products are opened on the lining body 10, so that the products that need to be kept fresh are not easily shifted during transportation; a partition wall 200 horizontally extending from the middle part of one side of the lining body 10 separates this part of the cavity, and a receiving groove 300 for receiving the fresh-keeping medium is formed between its lower side and the inner wall of the packaging box, and a cooling channel 400 connected to the receiving groove 300 is opened at the bottom of the lining body 10 from the cooling port 310 on one side of the receiving groove 300 along the other side. There is a distance between the end of the channel 400 and the side wall of the lining body 10 to better preserve the cold source air. A connecting port 500 is opened between the cold conduction channel 400 and the limiting groove 100 to form a connection, so that when the cold source gas in the accommodating groove 300 flows to the cold conduction channel 400, it can better flow from the connecting port 500 to the limiting groove 100, and both are arranged near the bottom. The cold air can be better preserved at the bottom of the limiting groove 100, and the preservation effect is better; the overall structure of the lining body 10 is simple, and through the cold conduction channel 400, it effectively saves space for placing the insulation medium and saves packaging costs.

[0022] Furthermore, the cooling channel 400 and the limiting grooves 100 are connected in series, and the limiting grooves 100 are arranged in parallel on both sides of the cooling channel 400. In this embodiment, the cooling channel and the connecting port are in a cross shape. Of course, in other embodiments, when the liner body 10 is circular, a circular cooling channel can be formed in series to achieve a cooling effect. By providing symmetrically distributed limiting grooves 100, the middle cooling channel 400 is connected to the limiting grooves 100 on both sides through the connecting port 500, the cold source utilization rate is high, and the cold air can flow evenly to the limiting grooves 100 on both sides to ensure the freshness preservation effect.

[0023] Furthermore, the partition wall 200 is connected to the liner body 10 in a flip-up manner; a lifting portion 210 is provided on the edge of the partition wall 200. During placement of the cooling medium, the partition wall 200 can be flipped open by operating the lifting portion 210 to place the cooling medium, facilitating operation. Furthermore, the cavity formed above the partition wall 200 can be used to place other products, resulting in high space utilization. In this embodiment, the partition wall 200 is provided with an arc-shaped notch to constitute the lifting portion 210. This arc-shaped notch facilitates easy opening and processing.

[0024] Furthermore, the lining body 10 is composed of several layers of flexible insulation boards 11 stacked together to form the limiting groove 100 and the cooling channel 400. In this embodiment, the lining body 10 is made of pearl cotton material to form a flexible insulation board 11. The flexible insulation board 11 is stacked in multiple layers to form the lining body 10. Relative grooves are opened in each insulation board 11 to form the limiting groove 100, the cooling channel 400 and the connecting port 500. There is no need to open the cooling channel 400 and the connecting port 500 from the inside, which effectively saves processing time and facilitates processing. Among them, one of the insulation boards 11 located in the middle extends horizontally to one side to form the partition wall 200, and the fixed plate 6 00 is connected to the bottom of the lining body 10; the lining body also includes a fixed plate, and a layer of the insulation plate 11 at the bottom extends toward the side of the partition wall 200 to form the fixed plate 600; a accommodating groove 300 for clamping the cold source medium is formed between the fixed plate 600 and the partition wall 200, so that when the cold source medium is placed, the temperature locking effect is better, and the cold source air can be better stored in the accommodating groove 300 and flow into the cold guide channel 400, thereby improving the thermal insulation effect, and no additional connection method is required to form the fixed plate 600 during processing, which effectively saves processing costs.

[0025] See Figure 4 This embodiment also provides a packaging box in which the above-mentioned liner is placed, comprising a box body 20 and a cover body 30. The above-mentioned liner body 10 is placed in the box body 20, and the liner body 10 is adapted to the shape of the inner cavity of the box body 20. The cover body 30 covers the box body 20. Snap-on walls 31 are provided on both sides of the cover body 30. The snap-on walls 31 are vertical and spaced apart from the side walls of the cover body 30. The spacing is adapted to the thickness of the side walls of the box body 20. The box body 20 is covered by the cover body 30 so that the cold air in the receiving groove 300 of the liner body 10 can be better utilized and not easily lost. The snap-on walls 31 extend outward from the side walls of the cover body 30 and form a vertical shape. The spacing between the snap-on walls 31 corresponds to the thickness of the side walls of the box body 20. When in use, the snap-on walls 31 snap into the side walls of the box body 20, allowing for quick closing and improving the heat preservation effect.
