When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] See also Figures 1 to 4 The salad fresh-keeping packaging box in the embodiment of the utility model includes a box body 10 and a top cover 20 for covering the box body 10. The box body 10 includes a bottom plate 110 and a side plate 120 connected to one side of the bottom plate 110. It can be understood that the side plate 120 includes four interconnected vertical plates, and the four vertical plates are arranged around the outer edge of the bottom plate 110. The side plate 120 and the bottom plate 110 enclose a storage space for accommodating salads.

[0026] The two opposite side walls of the side panel 120 are both rotatably connected to the rotating shaft 70, and extension rods 80 are provided on the two rotating shafts 70. A lifting rod 90 is connected between the two extension rods 80, and the extension rod 80 and the lifting rod 90 are formed in one piece. By providing the lifting rod 90 and the extension rod 80, the salad fresh-keeping packaging box can be easily moved. When placed, the lifting rod 90 can be placed on one side of the box body 10 through the rotating shaft 70 rotatably connected to the side panel 120 to prevent the lifting rod 90 from affecting the detachment or covering between the top cover 20 and the box body 10.

[0027] A first annular rubber ring 210 and a second annular rubber ring 220 are disposed on one side of the top cover 20 facing the box body 10. The first annular rubber ring 210 and the second annular rubber ring 220 are both disposed in a "mouth" shape, and the enclosed area of ​​the first annular rubber ring 210 is larger than the enclosed area of ​​the second annular rubber ring 220. The first annular rubber ring 210 is disposed around the outer edge of the top cover 20, and a sealing groove adapted to the top of the side panel 120 is formed between the first annular rubber ring 210 and the second annular rubber ring 220. By placing the top of the side panel 120 and the rest in the sealing groove, the sealing performance of the salad fresh-keeping packaging box can be improved, and the freshness of the salad placed therein can be improved.

[0028] The side walls opposite to the top cover 20 are provided with a buckle mechanism 60 to fix the top cover 20 to the box body 10. By providing the buckle mechanism 60, after the top of the side plate 120 is inserted into the sealing groove, the tightness of the connection between the box body 10 and the top cover 20 is improved to prevent the top cover 20 from being separated from the box body 10 due to collision or shaking. Specifically, the buckle mechanism 60 includes two support plates arranged opposite to each other, the two support plates are connected to the side walls of the top cover 20, and the two support plates are rotatably connected to the rotating shaft, and the rotating shaft outer shell is connected with a buckle. It can be understood that the buckle includes a straight portion fixedly connected to the rotating shaft, and the end of the straight portion away from the rotating shaft extends toward the side plate 120 to form an extension portion. The outer wall of the side plate 120 is provided with a slot corresponding to the buckle. By rotating the straight portion, the extension portion is inserted into the slot to complete the fixing between the top cover 20 and the box body 10.

[0029] The side plate 120 is concave on one side facing the bottom plate 110 to form a first cavity 121. The bottom plate 110 is provided with a second cavity 111. The first cavity 121 is connected to the second cavity 111 to form a water storage cavity. The water storage cavity is used to store ice water. The outer wall of the side plate 120 is provided with a water injection hole 122 connected to the first cavity 121. A first sealing plug 30 is arranged in the water injection hole 122. Preferably, the water injection hole 122 is located at the top of the first cavity 121. By removing the first sealing plug 30, ice water can be injected into the water storage cavity through the water injection hole 122 to complete the temperature control in the box body 10, better preserve the salad and reduce the probability of its deterioration. By connecting the first cavity 121 and the second cavity 111, the coverage of the ice water can be expanded to ensure that the salad is surrounded by ice water.

[0030] The second cavity 111 divides the bottom plate 110 into an upper plate 112 and a lower plate 113 which are distributed from top to bottom. A water outlet 114 is provided on the lower plate 113. The water outlet 114 is located at the center of the lower plate 113. By setting the water outlet 114, ice water can be discharged from the water storage cavity from the water outlet 114, so as to facilitate cleaning or replacement of ice water in the water storage cavity.

[0031] Furthermore, an inclined surface is formed on one side of the lower plate 113 facing the upper plate 112, and an acute angle is formed between the inclined surface and the outer wall of the lower plate 113, and the inclined surface is inclined from the side edge of the lower plate 113 toward the water outlet 114, that is, the cross-section of the lower plate 113 is an inverted trapezoid. By setting the inclined surface, a guiding and drainage effect can be provided when discharging ice water, ensuring that the ice water is completely discharged from the water storage chamber, thereby improving the cleaning or replacement efficiency. At the same time, it can prevent residual ice water from being retained in the water storage chamber for a long time, thereby affecting the cleanliness therein.

[0032] A placement plate 50 is provided on the side of the lower plate 113 facing away from the upper plate 112. It can be understood that the placement plate 50 has the same area as the bottom plate 110. A sealing column 510 is provided on the side of the placement plate 50 facing the lower plate 113. The sealing column 510 is adapted to the water outlet 114. By plugging the sealing column 510 into the water outlet 114, it is possible to prevent ice water from flowing out of the water outlet 114 during the preservation period. By providing the placement plate 50, the flatness of the bottom of the salad fresh-keeping packaging box can be ensured to avoid tilting or shaking during placement. In some embodiments, a pressing block is provided on the side wall opposite to the placement plate 50. By pressing the pressing block, the placement plate 50 can be quickly separated from the bottom plate 110, that is, the plug-in column can be quickly detached from the water outlet 114.

[0033] The side walls opposite to the side panel 120 are provided with an air inlet 123 and an air outlet 124, respectively. It can be understood that the air inlet 123 and the air outlet 124 are both arranged at one end of the side panel 120 facing the top cover 20, so as to prevent the salad in the salad fresh-keeping packaging box from blocking the air inlet 123 and / or the air outlet 124 and affecting the gas flow. The air inlet 123 is used to connect the nitrogen supply device, and the air inlet 123 and the air outlet 124 are both provided with a second sealing plug 40. The prepared salad is placed in the box body 10, and the top cover 20 covers the box body 10. By removing the two second sealing plugs 40, the nitrogen supply device is connected to the air inlet 123, nitrogen is injected into the box body 10, and air is discharged through the air outlet 124, so as to provide a better fresh-keeping environment for the salad in the box body 10.
