[0036] Reference Figures 1 to 6 A food storage container includes a container body 1 and a lid 2, both made of plastic. The container body 1 and lid 2 can be manufactured using injection molding machines or similar equipment to form a single, integrated structure, except for a sealing ring. The lid 2 includes a top cover and at least one fastening plate 23. The top cover has a sealing ring 3 that fits the upper end of the container body 1. One side of the top cover is integrally hinged to the container body 1. One end of the fastening plate 23 is integrally hinged to the top cover. A fixing plate 231 protrudes from the side of the fastening plate 23 near the container body 1. Two limiting protrusions 232 are spaced apart on the side of the fixing plate 231 near the container body 1. A frame 11 is provided on the outer side of the upper end of the container body 1. The lower end of the frame 11 has slots 12 with downward openings that correspond one-to-one with each of the limiting protrusions. When the lid 2 rotates downwards to close the upper opening of the box body 1, the lower end face of the sealing ring 3 abuts against the upper end face of the box body 1, and the fastening plate 23 can rotate downwards until the limiting protrusion 232 is embedded in the slot 12. Except for the sealing ring 3, the entire food storage container of this design is a one-piece connection structure. The lid 2 is not easily lost after opening, and the sealing ring 3 seals against the upper end face of the box body 1, preventing the sealing performance between the lid 2 and the box body 1 from deteriorating over time.
[0037] Specifically, the upper end of the box body 1 is horizontally protruding with an end plate 13. The frame 11 includes an annular first side plate 111. The upper end of the first side plate 111 is fixedly connected to the end plate 13. The first side plate 111 is sleeved on the outside of the box body 1 and has a gap between it and the outer side of the box body 1. The gap is used to form the slot 12. The top cover is integrally hinged to the lower end of the first side plate 111. When multiple products are unfolded and stacked together to save space, due to the gap between the first side plate 111 and the outer side of the box body 1, when two boxes 1 with the lid 2 open are stacked together, the upper box 1 can be inserted downward into the cavity of the lower box 1. The outer side of the upper box 1 will not be in close contact with the inner wall of the lower box 1 and will not be completely sucked shut, making it easy to remove the stacked boxes 1.
[0038] Specifically, the lower end of the first side plate 111 is provided with a protrusion 1111 corresponding to each of the limiting protrusions 232, and each of the limiting protrusions 232 can be embedded between the corresponding protrusion 1111 and the box body 1.
[0039] Specifically, each slot 12 further includes two parallel and spaced-apart limiting plates 112, with both ends of each limiting plate 112 fixedly connected to the protrusion 1111 and the box body 1, respectively, and each limiting protrusion 232 can be embedded between the two corresponding limiting plates 112.
[0040] Specifically, the top cover includes a top plate 21 and a second side plate 22. The upper end of the second side plate is integrally fixedly connected to the edge of the top plate 21, and the sealing ring 3 is located at the connection node between the top plate 21 and the second side plate 22. The second side plate 22 includes a first plate 221, a second plate 222, a third plate 223, and a fourth plate 224 connected end to end. The fourth plate 224 is integrally hinged to the lower end of the first side plate 111. The lower ends of the second plate 222 and / or the first plate 221 and the third plate 223 are integrally hinged to one end of the corresponding fastening plate 23. That is, the position and number of fastening plates 23 can be set according to the actual use or the size of the food storage container. When the size is small, a fastening plate 23 is set below the second plate 222. When the size is large, a fastening plate 23 is set below the first plate 221, the second plate 222, and the third plate 223.
[0041] Specifically, a connecting plate 4 is provided between the fourth plate 224 and the first side plate 111. One end of the connecting plate 4 is fixedly connected to the outside of the first side plate 111, and the other end is integrally hinged to the first plate 221.
[0042] Specifically, the outer side of the box body 1 is also provided with several ribs 14 at intervals, with two ribs 14 located at both ends of the connecting plate 4, and both ends of each rib 14 being fixedly connected to the box body 1 and the first side plate 111, respectively. The ribs 14 and the limiting plate 112 can strengthen the connection structure between the box body 1 and the end plate 13 and the first side plate 111, strengthen the structural strength of the opening end of the box body 1, and prevent damage to the opening end of the box body 1 when opening and closing, and prevent the sealing between the lid 2 and the box body 1 from deteriorating after long-term use. When multiple products are unfolded and stacked together to save space, that is, when the lids 2 of each food storage box are folded up and stacked together, the ribs 14 and the limiting plate 112 can limit the stacking distance between the top surfaces or end plates 13 of two adjacent box bodies 1, and a gap can be created between the two adjacent box bodies 1 stacked on top of each other, avoiding complete sealing and making it easy to remove. That is, due to the presence of the rib plate 14 and the limiting plate 112, the end plate 13 of the lower box 1 will not be tightly embedded in the slot 12 of the upper box 1, which can prevent the two adjacent boxes 1 or their end plates 13 from being tightly contacted and sucked together, making it easier to separate the stacked boxes 1.
[0043] Specifically, the top plate 21 has a positioning protrusion 211 on its upper surface, and the bottom of the box body 1 has a downward-facing limiting groove 161. The projection of the limiting groove 161 in the vertical direction can cover the projection of the positioning protrusion 211 in the vertical direction. When food storage boxes of the same or similar size with their lids 2 not opened are stacked together, the positioning protrusion 211 on the top plate 21 of the lower food storage box can be inserted into the limiting groove 161 on the bottom plate 16 of the upper food storage box, thereby limiting the displacement of the upper food storage box in the horizontal direction.
[0044] Specifically, the top plate 21 has an annular groove 212 with its opening facing upwards. The side of the positioning protrusion 211 forms a side wall within the groove 212, and the upper end face of the positioning protrusion 211 is not higher than the height of the opposite side wall within the groove 212. The side of the positioning protrusion 211 is inclined, and the cross-sectional size of the positioning protrusion 211 gradually increases from top to bottom. When food storage containers of the same or similar size with their lids 2 not opened are stacked together, the positioning protrusion 211 can be smoothly inserted into the limiting groove 161 on the bottom plate 16 of the upper food storage container without damaging the structure of the bottom plate 16. At this time, the outer edge of the bottom end of the container body 1 of the upper food storage container can be embedded in the groove 212.
[0045] Specifically, the box body 1 includes a third side plate 15 and a bottom plate. The third side plate 15 is cylindrical and its cross-sectional dimensions gradually decrease from top to bottom. The bottom plate 16 is fixedly connected to the third side plate 15 and seals the bottom opening of the third side plate 15. A receiving groove is formed above the bottom plate 16 and inside the third side plate 15. The limiting groove 161 is provided on the bottom plate 16. The upper end of the third side plate 15 is fixedly connected to the inner side of the frame 11. That is, the upper edge of the third side plate 15 is fixedly connected to the inner side of the end plate 13, and the outer side of the end plate 13 is fixedly connected to the inner side of the first side plate 111.
[0046] Specifically, an annular groove 24 is provided between the top plate 21 and the second side plate 22, and the sealing ring 3 is embedded in the annular groove 24.
[0047] Other aspects of the food storage container described in this utility model can be found in the prior art, and will not be repeated here.
[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
