[0005] As a further solution of the utility model, the edge of the box cover is provided with an annular upward curled edge, the annular upward curled edge is provided with a first rotating shaft, the annular downward curled edge is provided with a first shaft sleeve, the first rotating shaft is rotatably sleeved in the first shaft sleeve, that is, the box cover is flippably connected to the open box body through the rotational cooperation of the first rotating shaft and the first shaft sleeve.
[0006] As a further solution of the utility model, a second rotating shaft is provided on the annular upward curled edge, and a second sleeve is provided on the locking member. The second rotating shaft is rotatably sleeved in the second sleeve, that is, the locking member is locked or opened with the edge of the annular downward curled edge on the open box body through the rotational cooperation between the second rotating shaft and the second sleeve.
[0007] As a further solution of the utility model, an annular flange is provided on the annular downward curled edge, and a circle of annular grooves with a "U"-shaped cross-section and an opening facing downward is provided in the box cover near the annular upward curled edge. When the box cover is closed with the open box body, the annular groove and the annular flange are buckled, thereby realizing a sealed connection between the open box body and the box cover, so that the food contained therein is kept fresh.
[0008] As a further solution of the utility model, an end of the locking member away from the second rotating shaft is provided with an arc-shaped opening and closing portion. The arc-shaped design enhances the comfort when locking or opening, and can also serve as a handle when flipping the cover.
[0009] The utility model has the following advantages and effects: the overall structure is simple, and there are no sharp protruding parts, so that the sharp protruding parts can avoid scratching the plastic bag when the plastic bag is carried in a plastic bag set; the entire fresh-keeping box is made of stainless steel, can be washed completely, and is durable.
