In the scheme shown in the drawings of the present application, a rib structure protruding towards the direction of the second box 200 is formed on the first box 100, a groove structure recessed inwards from the direction of the first box 100 is formed on the second box 200, when the first box 100 is covered with the second box 200, the rib structure on the first box 100 is clamped into the recessed structure on the second box 200, so that the heating lunch box 10 is sealed, and the food in the heating lunch box 10 is prevented from leaking or spilling. Of course, a concave structure may be provided on the first container 100, and a rib structure may be provided on the second container 200, as long as the first container 100 and the second container 200 can be sealed. In addition, the cross-sectional shapes of the rib structures and the groove structures may be circular, triangular, polygonal, etc., and herein, there is no limitation thereto.

Further, in order to improve the stability of the sealing connection between the first box 100 and the second box 200, the first box 100 and the second box 200 are further provided with a first anti-falling part 122 and a second anti-falling part 222, and the first anti-falling part 122 and the second anti-falling part 222 are matched to fix the first box 100 and the second box 200 after being covered. Specifically, one of the first and second retaining

portions

122 and 222 is a locking protrusion, and the other is a locking recess, and when the first and

second cases

100 and 200 are closed, the locking protrusion is locked into the locking recess.

For example, the clamping protrusion is a clamping rib surrounding the edge of the first box 100, and the clamping recess is a clamping groove surrounding the edge of the second box 200. In the scheme shown in the figures of the present application, a clamping convex portion is formed on the first box 100, that is, a clamping rib is arranged around the edge of the first box 100, and a clamping concave portion is formed on the second box 200, that is, a clamping groove is arranged around the edge of the second box 200. Thus, when the first box 100 and the second box 200 are closed, the clamping ribs are clamped into the clamping grooves to enhance the connection stability between the first box 100 and the second box 200, so that the heating meal box 10 is prevented from being opened by external force during cooking or heating, the leakage or spilling of food is prevented, and the sealing performance of the heating meal box 10 is improved. Of course, a clamping groove may be provided on the first box 100, and a clamping rib may be provided on the second box 200, as long as the fixation between the first box 100 and the second box 200 can be strengthened. In addition, the cross-sectional shapes of the clamping grooves and the clamping ribs can be circular, triangular, polygonal and the like, and are not limited herein.

Alternatively, the snap protrusions may be protrusions spaced around the edge of the first container 100, and the snap recesses may be notches spaced around the edge of the second container 200. The plurality of protrusions and the plurality of recesses are spaced apart, preferably uniformly spaced apart, but may be non-uniformly spaced apart, at the edges of the first case 100 and the second case 200, respectively. The number of the protrusions and the recesses may be an odd number, such as 3 or 5, or an even number, such as 4 or 6, and the number of the protrusions and the recesses is not limited herein. When the first container 100 and the second container 200 are closed, the protrusions are correspondingly engaged with the recesses one by one, so that the first container 100 and the second container 200 are more stably fixed. Of course, a notch may be formed on the first box 100 and a protrusion may be formed on the second box 200, as long as the notch and the protrusion are connected in a clamping manner, and the first box 100 and the second box 200 are stably fixed. In addition, the cross-sectional shapes of the projections and the recesses may be circular, triangular, rectangular, etc., and herein, are not limited thereto.

Of course, the anti-separation structure between the first anti-separation portion 122 and the second anti-separation portion 222 can also be implemented by using a magnet, for example, the first anti-separation portion 122 and the second anti-separation portion 222 are both provided with magnetic stripes, and when the first box 100 and the second box 200 are closed, the magnetic attraction of the magnetic stripes is utilized to enhance the fixed connection between the first box 100 and the second box 200.

Further, in order to cook or heat various foods simultaneously, at least one first isolation rib 130 is formed in the middle of the first box 100, at least one second isolation rib 230 having the same number as the first isolation rib 130 is formed in the middle of the second box 200, and when the first box 100 is closed to the second box 200, the first isolation rib 130 contacts with the second isolation rib 230 to form at least two accommodating cavities 140. So, can hold different food in a plurality of holding chamber 140, make the cooking machine can cook or heat multiple food simultaneously, reduced the required time of multiple food culinary art or heating, improved the work efficiency of cooking machine.

In one embodiment, a ventilation structure is further disposed on one of the first container 100 and the second container 200, and the ventilation structure is used for releasing the expanding gas when the gas inside the heated lunch box 10 expands due to heating and the pressure reaches a predetermined value. The setting of ventilative structure has effectively avoided food at the in-process of culinary art or heating, because of the high temperature in the heating cutlery box 10, the pressure grow and make the condition that heating cutlery box 10 inflation was fried even, has strengthened the security of heating cutlery box 10 use. Specifically, the ventilation structure is a plurality of sets of ventilation holes 150, the ventilation holes 150 may be disposed on any one of the first box 100 and the second box 200, or on both of the first box and the second box, and may be disposed on the side wall or the bottom wall or other portions of the box, and the ventilation holes 150 may be circular holes, square holes or irregular holes, so that the shapes, the number and the positions of the ventilation holes 150 are not limited, as long as the ventilation holes can release the expanding gas when the gas in the heating lunch box 10 is expanded by heat to cause the pressure to reach a preset value. Of course, the ventilation structure can be other structures such as an open cover type structure.

In one embodiment, the first container 100 includes a first cover 110 and a first flange 120 connected to an edge of the first container 100, the first flange 120 is formed with a first sealing portion 121 and a first anti-slip portion 122, the second container 200 includes a second cover 210 and a second flange 220 connected to an edge of the second container 200, the second flange 220 is formed with a second sealing portion 221 and a second anti-slip portion 222, when the first container 100 and the second container 200 are closed, the first cover 110 and the second cover 210 are disposed opposite to each other, the first flange 120 and the second flange 220 abut against each other, the first sealing portion 121 and the second sealing portion 221 contact each other, and the first anti-slip portion 122 and the second anti-slip portion 222 contact each other. Therefore, the accommodating cavity 140 capable of accommodating food is formed between the first cover cap 110 and the second cover cap 210, so that the food can be turned in the accommodating cavity 140, when the cooker is used for cooking or heating, the food is conveniently and uniformly heated in the accommodating cavity 140, and the cooking or heating efficiency of the food is improved. The first sealing part 121 and the second sealing part 221 are matched to ensure the sealing performance of the food in the heating lunch box 10, so that the food is prevented from leaking or spilling. The cooperation of first anticreep portion 122 and second anticreep portion 222 provides double assurance for the sealing connection of heating cutlery box 10, has avoided heating cutlery box 10 receiving under the circumstances such as external force, the separation between first box 100 and the second box 200, the seepage or the spill of the food that leads to for the connection between first box 100 and the second box 200 is more stable.
