DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are merely some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] Please refer to Figures 1 to 7 The embodiment of the present application provides a food packaging box, which comprises:

[0036] The box body 1 is provided with a first placement cavity 10.

[0037] The cover 2 is connected to one end of the box body 1, and the cover 2 is reversibly buckled on the box body 1.

[0038] The lower box body 3 is provided with a second placement cavity 30, and the box body 1 is buckled on the lower box body 3.

[0039] The front surface of the edge of the first placement cavity 10 of the box body 1 is provided with an annular protrusion 11, the inner side of the cover 2 is provided with an annular inner wall 21, and the annular inner wall 21 of the cover 2 is reversibly buckled on the annular protrusion 11 of the box body 1.

[0040] Further, the bottom of the annular protrusion 11 is provided with an annular groove 12, and the annular inner wall 21 is respectively provided with an arc protrusion 22 around. When the annular inner wall 21 is buckled on the annular protrusion 11, the arc protrusion 22 is clamped on the annular groove 12. By clamping the arc protrusion 22 on the annular groove 12, the cover 2 is buckled on the box body 1 more tightly.

[0041] Further, the upper and lower ends of the arc protrusion 22 are respectively provided with chamfer portions 220. The chamfer portions 220 facilitate the arc protrusion 22 to pass through the annular protrusion 11, thereby facilitating the closing or opening of the cover 2.

[0042] Further, the front surface of the edge of the first placing cavity 10 and the inner side of the annular boss 11 are provided with an annular step 13, and the inner side of the annular inner wall 21 is provided with an annular blocking wall 23. When the annular inner wall 21 is buckled on the annular boss 11, the annular blocking wall 23 abuts on the annular step 13. By abutting the annular blocking wall 23 on the annular step 13, the sealing of the first placing cavity 10 is ensured, so as to avoid the food from flowing out of the first placing cavity 10.

[0043] Further, the one end of the box cover 2 and the one end of the box body 1 are provided with a flap 28, the flap 28 is provided with a first ventilation groove 281, and the one end of the annular inner wall 21 is provided with a plurality of exhaust ports 280 which are communicated with the first ventilation groove 281. When the annular inner wall 21 of the box cover 2 is reversely buckled on the annular boss 11 of the box body 1, the flap 28 is folded, so that the first ventilation groove 281 is located between the flaps 28. Moreover, the exhaust port 280 also penetrates through the annular blocking wall 23, and the exhaust port 280 is communicated with the first ventilation groove 281 by penetrating through the annular inner wall 21 and the annular blocking wall 23 in sequence, so as to realize the communication between the first ventilation groove 281 and the box body 1. When the box body 1 needs to be exhausted, the water vapor is exhausted to the first ventilation groove 281 through the exhaust port 280.

[0044] Further, the first air vent 281 is provided with a second air vent 282 which is symmetrically arranged with the first air vent 281, and the two ends of the first air vent 281 and the second air vent 282 are respectively provided with air guide parts 283. When the annular inner wall 21 of the box cover 2 is reversely buckled on the annular boss 11 of the box body 1, the flaps 28 are folded in half, so that the first air vent 281 and the second air vent 282 are symmetrically buckled together, and the two ends of the folded flaps 28 form air vent gaps 284. The advantage of this structure is that when the annular inner wall 21 of the box cover 2 is reversely buckled on the annular boss 11 of the box body 1, the box cover 2 and the box body 1 are sent into the microwave oven for heating, and the internal moisture of the food in the box body 1 will evaporate and generate water vapor. Since the microwave oven heats by vibrating the water molecules in the food, a large amount of water vapor will be generated in a short time. If this water vapor is retained in the box body 1, the internal air pressure will rise in the closed space. According to the physical law (principle of fluid mechanics), gas always flows from high pressure area to low pressure area. If the box body 1 is sealed, the worst case is that the box cover 2 may be deformed or damaged when the internal air pressure continuously rises. Therefore, the above-mentioned exhaust structure is needed to reasonably exhaust the water vapor. Therefore, the action mechanism of the above-mentioned exhaust structure is that the water vapor in the box body 1 is exhausted through the exhaust port 280 to the space between the first air vent 281 and the second air vent 282, so that the air pressure in the box body 1 is stable, the water vapor is effectively exhausted to the outside through the air pressure difference, and the box cover 2 is prevented from being excessively expanded or suddenly popped open. In addition, in the process of exhausting to the outside, the water vapor first passes between the first air vent 281 and the second air vent 282, then passes through the air guide part 283, and finally flows out of the outside through the air vent gap 284. In this process, the cooled water vapor will not be directly exhausted to the outside, but will be retained between the first air vent 281 and the second air vent 282, so as to avoid the cooled water vapor from making the outside environment wet.

[0045] Further, the edge of the annular boss 11 is provided with a first flap 14, and the edge of the annular inner wall 21 is provided with a second flap 24. When the annular inner wall 21 is buckled on the annular boss 11, the first flap 14 and the second flap 24 are attached, and the two sides of one end of the first flap 14 and the second flap 24 are respectively provided with a tearable ear 27. Through the structure of the tearable ear 27, the opening of the box cover 2 is facilitated.

[0046] The back of the edge of the first placing cavity 10 of the box body 1 is provided with an annular recess 15, and the edge of the second placing cavity 30 of the lower box body 3 is provided with an annular clamping edge 35. The annular recess 15 of the box body 1 is buckled on the annular clamping edge 35 of the lower box body 3.

[0047] Further, the annular boss 11 is arranged opposite to the annular recess 15, that is, the back of the annular boss 11 is the annular recess 15, and the front of the annular recess 15 is the annular boss 11.

[0048] The box body 1 and the box cover 2 are both plastic material components, and the lower box body 3 is a paper material component.

[0049] The first placing cavity 10 is surrounded by a plurality of reinforcing strips 19 on the inner side.

[0050] In summary, the food packaging box of the embodiment has the following advantages:

[0051] 1. One end of the box cover 2 and the box body 1 is connected by the folding piece 28, when the user opens the box cover 2 and uses the box body 1, the box cover 2 is still connected to one end of the box body 1, so that the user does not lose the box cover 2, and the user can fold and buckle the box cover 2 on the box body 1 at any time.

[0052] 2. The double-layer food storage function is realized, and the green environmental protection purpose is achieved, the lower box body 3 made of paper material can contain solid food, the paper material is environmentally friendly, the box body 1 made of plastic material can contain liquid food, the plastic material ensures that the liquid does not penetrate into the box body 1, and the liquid food is not leaked.

[0053] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
