[0002] The existing sealed fresh-keeping box includes a container body and a lid. For easy opening, application No. EP3995058B1 discloses a container with a lever hinged on the lid. The lever includes a gripping portion suitable for being gripped and actuated by a user and an operating portion suitable for abutting against the flange of the container body, which protrudes outward relative to the top edge of the container body. When operating, the gripping portion is operated and the operating portion hits the outer flange of the container, so that the lid is lifted and separated from the container body according to the lever principle. Since the container is usually a sealed container, in order to reduce the pressure difference between the inside and outside of the container for easy opening, a through hole is provided on the lid, and a pin that seals with the through hole is provided on the control rod. During the movement of the control rod between the closed position and the open position, the pin seals the through hole or detaches from the through hole. Since the pin is fixed on the control rod, the lid needs to be pressed tightly to seal against the container body, and at this time, the pin on the control rod also directly seals the through hole, so that the gas in the container is difficult to be discharged smoothly, resulting in the air pressure in the container being greater than the air pressure outside the container, making it difficult to cover. Summary of the invention

[0018] Embodiments of the present utility model: Figures 1 to 6As shown, a sealed fresh-keeping box comprises a container body 1 with an edge and a lid 2 that can be covered on the container body 1. The outer surface of the lid 2 has a concave cavity 3, and a lever 6 including a holding part 4 and an operating part 5 is hinged in the concave cavity 3. When the lid 2 is covered on the container body 1, the edge of the container body 1 touches the operating part 5 of the lever 6 to rotate the holding part 4 downward, and the holding part 4 is lifted to make the operating part 5 hit the edge of the container body, so that the lid 2 is lifted and separated from the container body 1 according to the lever principle. In the present application, a through hole 7 is provided at the bottom of the concave cavity 3 of the lid 2, and a sealing component 8 that cooperates with the through hole 7 for sealing is provided on the lever 6. Specifically, a mounting hole 9 is provided in the middle of the lever 6, and the sealing component 8 is slidably connected to the mounting hole 9. When the lid 2 is covered on the container body 1, the edge of the container body 1 touches the operating part 5 of the lever 6 to rotate the holding part 4 downward to a horizontal state. The sealing component 8 is located directly above the through hole 7. During the covering process, the air in the container body 1 can be discharged through the through hole 7. After covering, the sealing component 8 slides down and inserts into the through hole 7 to seal it, so that the air pressure inside and outside the container is balanced, which facilitates the sealing of the lid 2 on the container body 1. When opening the lid 2, first slide the sealing component 8 upward to pull it out of the through hole 7 to balance the air pressure inside and outside the container, and then lift the holding part 4 to make the operating part 5 hit the edge of the container body, so that the lid 2 is lifted and separated from the container body 1 according to the lever principle.

[0019] As a preferred embodiment, in order to facilitate installation and prevent the sealing component 8 from being separated from the lever 6 during use, a matching limiting mechanism is provided between the lever 6 and the sealing component 8, and the limiting mechanism includes an annular protrusion 10 located on the inner wall of the mounting hole 9. The sealing component 8 includes a sliding member 11 and a sealing head 12. The sealing head 12 is made of an elastic material such as silicone and is clamped at the end of the sliding member 11. The sliding member 11 and the sealing head 12 both have a resisting portion that resists the annular protrusion 10. After the sliding member 11 and the sealing head 12 are clamped, they are respectively Located on the upper and lower sides of the annular protrusion 10, the annular protrusion 10 blocks the sealing head 12 when sliding upward, and blocks the sliding member 11 when sliding downward, thereby preventing the sealing assembly 8 from detaching from the lever 6. To facilitate opening the lid 2, in the closed state, when the sealing assembly 8 of the present application is in a position to be inserted into the through hole 7 to seal it, the annular protrusion 10 resists the sliding member 11. When the retaining part 4 of the lever 6 is lifted to separate the lid 2 from the container body 1, the sealing assembly 8 will be driven to be pulled out of the through hole 7 as it moves.

[0020] As a preferred embodiment, when the lid 2 is covered on the container body 1, the upper surface of the lever 6 is flush with the upper surface of the lid 2, which has a good overall appearance and is not easy to accidentally touch the lever 6 in the closed state. In order to facilitate the operation of lifting the holding part 4 of the lever 6 to open the lid 2, as shown in FIG. Figure 1 As shown, the holding portion 4 may have an opening 13 for fingers or as shown in FIG. Figure 2 The cavity shown also has space for fingers to enter and lift the holding part 4.

[0021] As a preferred embodiment, when the sealing component 8 is in the position of being inserted into the through hole 7 to seal it, the upper surface of the sealing component 8 is not higher than the upper surface of the lever 6. It is best when the sealing component 8 is flush with the upper surface of the lever 6, which has a good overall appearance and is not easy to be accidentally touched in the closed state.
