[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0025] like Figure 1As shown in one embodiment of this utility model, the insulated tableware box includes a lid 1, a main box 2, a heat insulation body 4, and a heat conductor 5. The main box 2 has a placement cavity 201 inside. The lid 1 is detachably connected to the main box 2 and is disposed above the placement cavity 201. The main box 2 has an assembly gap inside. The heat insulation body 4 and the heat conductor 5 are sequentially stacked and connected inside the assembly gap along the main body of the main box 2 toward the placement cavity 201.

[0026] The technical solution of this utility model uses a heat conductor on the inner side of the main box to conduct heat to the placement cavity, thereby reducing heat loss of the food inside the placement cavity; it also uses a heat conductor on the outside of the interlayer in the main box to prevent heat loss to the outside, which would reduce the heat preservation performance of the internal placement cavity, thereby improving the heat preservation effect of the food.

[0027] Specifically, in some implementations, such as Figure 1 and 2 As shown, the heat conductor 5 has an internal cavity 51; the heat conductor 5 also has a heating injection hole 202 communicating with the internal cavity 51; the heating injection hole 201 has a first control valve; the heat conductor 5 also has a discharge hole 203 communicating with the internal cavity 51; the discharge hole 203 has a second control valve. The first control valve is positioned above the second control valve; and the end of the first control valve away from the heat conductor 5 passes through the outer surface of the main housing 2; the end of the second control valve away from the heat conductor 5 passes through the outer surface of the main housing 2. This structure, through the controlled injection and discharge functions of the first and second control valves, ensures convenient replacement of the internal heat medium, thereby improving ease of use. Further, the heat conductor 5 is made of a heat-conducting metal material; preferably stainless steel.

[0028] Specifically, in some implementations, such as Figure 2 and 3 As shown, the inner bottom of the receiving cavity 51 is provided with a discharge ramp 511; and the height of the discharge ramp 511 near the discharge hole 203 is greater than the height of the discharge ramp 511 away from the discharge hole 203. There are two discharge ramps 511, symmetrically arranged on both sides of the discharge hole 203. That is, the two discharge ramps 511 form a V-shaped discharge surface to avoid excessive residual heat medium inside the receiving cavity 51, which could cause corrosion and other phenomena; thereby extending its service life and improving its operational stability.

[0029] Specifically, in some embodiments, the heat conductor 5 and the heat insulation body 4 are bonded together; and the heat insulation body 4 is made of ceramic heat insulation material. This structure can ensure its heat insulation performance through the use of ceramic heat insulation material, and can also reduce harm to users.

[0030] Specifically, in some implementations, such as Figure 2 and 3 As shown, the main box body 2 includes an outer plastic layer 21 and an inner metal layer 22; the inner metal layer 22 is stacked and connected to the inner side of the outer plastic layer 21; and the assembly gap is formed between the outer plastic layer 21 and the inner metal layer 22. That is, the heat insulation body 4 and the heat conductor 5 are stacked and connected sequentially in the assembly gap between the outer plastic layer 21 and the inner metal layer 22 along the direction of the main box body 2 toward the placement cavity 201. Among them, the heat insulation body 4 is bonded to the outer plastic layer 21; the heat conductor 5 is bonded to the inner metal layer 22. Further, the inner metal layer 22 is made of (304) stainless steel; the outer plastic layer 21 is made of polypropylene (PP) or polystyrene (PS). This structure reduces the sound and external stress of the lunch box being dropped or placed by the polypropylene (PP) or polystyrene (PS) of the outer plastic layer 21; thereby improving the stability of use; and the non-toxic properties of (304) stainless steel ensure the safety of the lunch box.

[0031] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the inner metal layer 22 has a positioning post 221 on its inner surface facing the placement cavity 201; the main box 2 has a partition 3 inside; the partition is snapped onto the outer surface of the positioning post 221. Wherein, as... Figure 1 As shown, the side end of the partition 3 is provided with an assembly groove 301 corresponding to the positioning post 221. That is, the partition 3 is engaged with the interior of the main box 2 along the positioning post 221; that is, the outer wall of the positioning post 221 is in close contact with the inner wall of the assembly groove 301. Further, the side end of the positioning post 221 is provided with at least one limiting protrusion 222; the upper surface of the limiting protrusion 222 abuts against the partition 3. This structure, through the supporting action of the limiting protrusion 222, realizes the function of the partition 3 in separating the placement cavity 201, thereby realizing the function of layered food placement. Furthermore, as... Figure 1 As shown, the partition 3 is provided with at least one through hole 302; the through hole 302 is set to penetrate the thickness of the partition 3; so as to allow some of the soup from the dishes to flow into the staple food at the bottom, thereby improving the comfort of eating.

[0032] Specifically, in some implementations, such as Figure 1 and 4As shown, the cover 11 includes a support plate 11 and a heat insulation plate 12 stacked together; the heat insulation plate 12 is snapped into the opening of the placement cavity 201. This structure, through the heat insulation treatment of the upper part and the heat insulation treatment of the sides and bottom of the heat insulation plate 12, can further improve its heat insulation efficiency, thereby reducing heat loss of the food inside the placement cavity and improving the heat preservation effect of the food. The support plate 11 and the heat insulation plate 12 form a stepped structure to improve the compactness and stability of the assembly.

[0033] Specifically, in some implementations, such as Figure 4 As shown, the heat insulation board 12 has a filled inner cavity; the heat insulation board 12 has a foaming injection hole 122 communicating with the filled inner cavity; the filled inner cavity contains a heat insulation foam 121. The heat insulation foam 121 is made of extruded polystyrene foam or polyurethane foam. Further, the bottom of the heat insulation board 12 has at least one locking post 102; the top of the positioning post 221 has a locking hole 223 corresponding to the locking post 102, to improve assembly stability.

[0034] Specifically, in some implementations, such as Figure 2 and 4 As shown, at least one handle block 101 is provided on the side end of the cover 11 (middle support plate 11). This structure can improve the convenience of opening or closing.
