[0039] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0040] A heat preservation box in the present application comprises a box body 1, a box cover 2 and a support plate 3.
[0041] Specifically, referring to Figure 1 , Figure 2 , Figure 9 and Figure 10 , the top of the box body 1 is open, and a cavity for accommodating heat preservation or cold preservation articles is formed in the box body 1. The box cover 2 is detachably covered on the above-mentioned box body 1, and is used to close the above-mentioned article cavity. The support plate 3 is protruded on the inner wall of the box body 1, and is formed with a stepped surface in combination with the inner wall of the box body 1. The stepped surface can be used to support the food tray 6 in the box body 1 (the food tray 6 here has a bent edge, which can be arranged on the stepped surface), so that the bottom of the food tray 6 does not contact the bottom of the box body 1. On the one hand, the food tray 6 is stable, preventing the food from shaking in the box body 1; on the other hand, when the bottom of the food tray 6 does not contact the bottom of the box body 1, a certain space will be left between the bottom of the food tray 6 and the box body 1. The still air layer formed by the space can effectively slow down the heat transfer, and play a role in strengthening the heat preservation. Of course, the food tray 6 can also not be provided with a bent edge, and can be directly placed in the box body 1.
[0042] And a gap for accommodating the food tray 6 is left between the box cover 2 and the support plate 3. The upper and lower heights of the gap are greater than the edge thickness of the conventional food tray 6, so as to accommodate the food tray 6.
[0043] In the embodiment, the material of the food tray 6 is food grade, which is convenient for placing and taking food, and prevents the food from being contaminated or damaged. In addition, referring to Figures 8 to 10 , the size of the food tray 6 can be reasonably arranged according to needs. The food tray 6 of the same size as the cavity of the box body 1 can be placed in the box body 1, or food trays 6 of different sizes can be placed in the box body 1. The partition plate can be provided or not provided, so that the arrangement position of the food tray 6 can be flexibly configured and adjusted.
[0044] For the above support plate 3, refer to Figure 2 and Figure 7 It can be arranged around the periphery of the storage cavity, or it can be arranged on opposite sides in the storage cavity. Moreover, the support plate 3 can be enclosed to form a support structure, or it can be distributed in the storage cavity.
[0045] When the support plate 3 is distributed in the box body 1, a spacing groove 30 is formed between adjacent support plates 3, and an ice plate or a partition plate is inserted in the spacing groove 30. Specifically, an ice plate can be inserted at the spacing groove 30 on the side wall of the box body 1, and an ice plate or a partition plate can be inserted in the spacing groove 30 in the middle of the box body 1 to achieve the effect of separating and insulating the items to be insulated. When the support plate 3 is arranged around the periphery of the storage cavity, the ice plate can be placed on the bottom surface of the box body 1. The material of the ice plate is a phase change material, which can automatically balance the temperature, prolong the effective cooling time, and is lightweight and easy to carry.
[0046] In this embodiment, the box body 1 and the box cover 2 are made of EPP (expanded polypropylene) material. The closed cell structure of EPP material can effectively slow down heat conduction and can withstand a temperature range of -40°C to 130°C, which can avoid deformation due to high temperature or brittle cracking due to low temperature. Moreover, EPP can quickly rebound after being squeezed and is not easy to deform, even if it is dropped or collided multiple times, it is not easy to break, and the service life is relatively long. Its bearing capacity is better than EPS (polystyrene foam), which is suitable for stacking transportation or heavy storage. EPP is also extremely light (density about 0.02~0.08g / cm³), which can reduce the burden of carrying and reduce logistics costs. Most importantly, it is 100% recyclable and degradable, and has high environmental protection; the surface is hydrophobic, and stains are not easy to penetrate, which can be directly wiped or washed.
[0047] To realize the tight cover between the box body 1 and the box cover 2, refer to Figures 2 to 4 In this embodiment, a first groove 10 is provided on the top outer edge of the box body 1, and a first flange 20 matched with the first groove 10 is provided on the bottom of the box cover 2. Therefore, the first flange 20 can be embedded in the first groove 10, so that the box body 1 and the box cover 2 can be tightly matched to ensure the sealing and cover stability.
[0048] To realize the stable stacking of the insulation boxes, a second groove 21 is provided on the top outer edge of the box cover 2, and a second flange 11 matched with the second groove 21 is provided on the bottom of the box body 1. Therefore, the second flange 11 can be embedded in the second groove 21 to form a tight fit between the insulation boxes, thereby realizing the stable stacking of multiple insulation boxes.
[0049] In addition, the first recess 10 and the second flange 11 can be matched to realize cover-free stacking, that is, the boxes 1 are directly stacked, and only the box cover 2 is needed on the topmost box 1.
[0050] Since the temperature-maintaining box and the temperature-maintaining box can generate local low pressure at the stacking abutment when stacked, the external atmospheric pressure can extrude the temperature-maintaining box, and a larger force is needed to separate the temperature-maintaining boxes. In this embodiment, the air gap 12 is inwardly recessed on the front and rear sides of the box 1, and is used for exhaust at the stacking abutment. The size, shape and number of the air gap 12 can be reasonably arranged according to the needs.
[0051] The box 1 is inwardly recessed on the two sides to form the handle groove 13, thereby facilitating manual carrying. The profile of the handle groove 13 is ergonomically designed, facilitating hand holding and demolding. Meanwhile, the inner surface of the handle groove 13 is provided with anti-skid lines (not shown in the figure) to prevent slipping accidents during carrying.
[0052] In this embodiment, referring to Figure 1 The top of the box cover 2 is provided with the visual window plate 22 made of transparent material, which can be made of transparent tempered glass, polycarbonate material or polymethyl methacrylate material (i.e. acrylic), thereby facilitating observation of the state of the articles in the box 1. Of course, the visual window plate 22 can not be provided, and the whole box cover 2 is directly provided on the box 1.
[0053] In order to stably combine the visual window plate 22 with the box cover 2, in this embodiment, referring to Figures 5 to 6 The box cover 2 is provided with the clamping groove 23 for clamping the visual window plate 22, thereby limiting and fixing the visual window plate 22. The clamping groove 23 can be further provided with the protrusion 230, and the visual window plate 22 is further stably limited by the cooperation of the clamping groove 23 and the protrusion 230. The protrusion 230 can be provided or not provided. The shape of the protrusion 230 can be semicylindrical, long strip-shaped or other special-shaped structures. In addition, the protrusion 230 can be provided with one or multiple protrusions, which are arranged at different positions.
[0054] In addition, the two sides of the box cover 2 are provided with the slot 24, thereby facilitating auxiliary opening of the box cover 2. The inner wall of the box cover 2 is inwardly protruded to form the reinforcing column 25, which is uniformly distributed on the inner wall, thereby enhancing the structural strength of the box cover 2.
[0055] Referring to Figure 4 The box cover 2 is further provided with the limiting ring 4 extending to the support plate 3, and the limiting ring 4 and the support plate 3 form the limiting groove 5, thereby avoiding jumping and shaking of the article box carrying the articles.
[0056] In summary, the utility model discloses a kind of heat preservation box, strong structural stability can satisfy the rigorous requirement of long-distance transport;High use convenience greatly reduces the labor intensity of operator;Long service life;Environmental protection performance is outstanding, meet the development requirement of modern green logistics.
