[0028] In the prior art, the fresh-keeping tray has a low structural strength and is prone to deformation or rupture when subjected to external pressure.

[0029] To this end, the present application provides a fresh-keeping tray that can solve the problems existing in the prior art. The technical solutions provided by the present application are described in detail one by one below.

[0030] Figure 1 This is a schematic diagram of the structure of a fresh-keeping tray according to an embodiment of the present application. The fresh-keeping tray includes a tray body, and a cavity is provided inside the tray body, in which fresh food can be placed. The tray body includes a bottom 100 and a side wall 200 arranged upward around the edge of the bottom 100, and the upper surface of the bottom 100 is provided with at least one downwardly recessed liquid collecting groove 110. The liquid collecting groove 110 can not only collect the liquid exuded from the fresh food in the tray, but also prevent the exudate accumulated in the bottom 100 from directly contacting the food, thereby preventing the fresh food from spoiling; at the same time, the presence of the groove enables the bottom 100 to better disperse stress when bearing weight, reduce the possibility of deformation, and increase the structural strength of the bottom 100 of the tray. The upper edge of the side wall 200 is provided with a top flange 300, and the top flange 300 is a curling structure to increase the structural strength of the box body frame. The top flange 300 and the side wall 200 are both recessed into the interior of the tray body to form an arched structure. By evenly distributing the force over the entire structure, the arched design can effectively withstand greater loads and improve overall stability and durability, which makes the tray more resistant to deformation and damage during use.

[0031] Optional, such as Figure 2 As shown, in some embodiments, the ratio of the depression depth a to the arch span b of the arch structure is between 0.01 and 0.1. By optimizing the ratio of the depression depth to the span, the tray body can achieve the best balance between the filling capacity, structural strength and material usage.

[0032] In some embodiments, the top flange 300 is formed by deforming the upper edge of the side wall 200 to extend outward. Figure 3 and Figure 4 As shown, the upper edge of the side wall 200 first extends outward in a direction away from the inside of the tray body to form a horizontal flange 310, which is integrally formed with the upper edge of the side wall 200; the outer end of the horizontal flange 310 continues to extend downwardly and obliquely to form an arc edge 320; the outer end of the arc edge 320 continues to extend in a direction away from the tray body to form a slight warp. The combination of the horizontal flange 310 and the arc edge 320 forms a cross section similar to an inverted U shape at the upper edge of the side wall 200, which increases the deformation resistance and overall rigidity of the top of the tray body, reduces the possibility of deformation during use, and also provides better convenience for holding and carrying.

[0033] In some embodiments, a reinforcing arc 400 is provided at the corner where the adjacent side walls 200 and the bottom 100 intersect at three faces for transition. As Figure 1 and Figure 2 shown, reinforcing arcs 400 are provided at the four corners where the side walls 200 and the bottom 100 intersect for transition. The arcs are connected to the bottom 100 and two adjacent side walls 200, and the thickness of the material used is greater than the thickness of the bottom 100 and the side walls 200. During the use of the fresh-keeping tray in the embodiment, the intersection angles where the adjacent side walls 200 and the bottom 100 intersect often bear more impacts and squeezes. By adopting a thickening design at the intersection angles, it can effectively avoid the corner deformation or breakage caused by the impact on the box body. At the same time, the reinforcing arc 400 connects the three faces more firmly together, providing a more stable framework for the main body of the tray.

[0034] Further, in some embodiments, a crescent-shaped reinforcing platform 500 is provided between the reinforcing arc 400 and the top flange 300. As Figure 1 and Figure 2 shown, the inner arc edge of the reinforcing platform 500 is connected to the upper edge of the reinforcing arc 400, and the outer arc edge is connected to the top flange 300. The reinforcing platform 500 is located in the corner area of the tray. These areas are often stress concentration points when subjected to diagonal pressure. The reinforcing platform 500 provides additional support through its structure to help bear and disperse these concentrated stresses, ensuring the structural stability of the main body of the tray.

[0035] In some embodiments, a plurality of longitudinally distributed inner grooves 210 are provided on the surface of the side wall 200 facing the inside of the main body of the tray. As Figure 1 shown, these inner grooves 210 start from the upper edge of the side wall 200 and extend all the way to the bottom 100. These inner grooves 210 form a continuous support structure in the vertical direction, which can effectively enhance the overall strength of the tray, especially when bearing vertical pressure, providing better support. At the same time, these inner grooves 210 are connected to both the side wall 200 and the bottom 100, enhancing the connection rigidity between the side wall 200 and the bottom 100, and preventing the side wall 200 from bending and deforming outward when carrying heavy objects. It can be understood that the inner grooves 210 can also play a role in guiding the seepage liquid on the side wall 200 to the bottom 100.

[0036] In some embodiments, the inner surface of the main body of the tray is a smooth surface, and the outer surface of the main body of the tray is provided with a mesh pattern. Setting the outer surface of the main body of the tray with a mesh pattern can increase the friction between the box body and the tabletop on which the box body is placed, improving the grasping force of the user during the use process, making it more stable during handling and stacking, and reducing the risk of slipping. And setting the inner surface of the main body of the tray as a smooth surface, the smooth inner surface reduces the friction between the food and the tray, helping to protect the integrity of the food surface and avoiding damage or scratches caused by pressing patterns on the food surface.

[0037] In some embodiments, the liquid collecting tank 110 is arranged in a ring on the upper surface of the bottom 100, as Figure 1 and Figure 2 shown. Compared with arranging a plurality of mutually independent liquid collecting tanks 110 on the bottom 100, arranging the liquid collecting tank 110 in a ring on the bottom 100 can effectively collect the seepage liquid from all directions, and at the same time evenly disperse the accumulated liquid in the liquid collecting tank 110. It avoids the situation that some liquid collecting tanks 110 at some positions are already full while some liquid collecting tanks 110 at other positions have no accumulated liquid due to the uneven seepage of the fresh products.

[0038] In some embodiments, absorbent paper is laid on the bottom 100 of the tray body. In other embodiments, absorbent cotton is filled in the liquid collecting tank 110. Both the absorbent paper and the absorbent cotton can absorb the seepage liquid of the fresh products and avoid the accumulation of liquid at the bottom 100 of the tray.

[0039] The embodiments of the present application have been described in detail above in conjunction with the accompanying drawings. However, the present application is not limited to the above embodiments. Various changes can be made without departing from the purpose of the present application within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
