When the closed ring 4 is used in conjunction with the bowl body 1, the bowl body 1 and the bowl cover 3 can be closed and reinforced through the closed ring 4 to avoid the bowl body 1 being squeezed and deformed by external force after closing, resulting in an opening at the closed part of the bowl cover 3, thereby improving the closing stability of the bowl body 1.
[0033] Reference Figure 2-Figure 4 In a preferred embodiment, a wrapping groove 13 located on the inner side of the outer ring 6 is opened at the bottom of the bowl cover 3, and the top of the bowl body 1 is located inside the wrapping groove 13. When the bowl cover 3 is used in conjunction with the bowl body 1, a space can be provided for the bowl cover 3 to close and wrap the top of the bowl body 1, thereby avoiding the situation where it is difficult to effectively wrap and close the top of the bowl body 1 when the bowl cover 3 is used. Therefore, the closing effect of the bowl cover 3 is improved. A contact ring 14 is fixedly connected to the top of the inner wall of the wrapping groove 13, and the bottom of the contact ring 14 is in tight contact with the top of the bowl body 1. When the wrapping groove 13 is used in conjunction with the bowl body 1, contact sealing can be performed between the bowl body 1 and the wrapping groove 13, thereby avoiding the situation where it is difficult to effectively wrap and seal the top of the bowl body 1 when the wrapping groove 13 is used. Therefore, the sealing effect of the wrapping groove 13 is improved.
[0034] Reference Figure 2-Figure 4In a preferred embodiment, a dislocation ring 15 is fixedly connected to the bottom of the contact ring 14, and the bottom of the dislocation ring 15 is plugged into and matched with the top of the bowl body 1. When the contact ring 14 is used in conjunction with the wrapping groove 13, the wrapping groove 13 and the top of the bowl body 1 can be plugged and dislocated by the contact ring 14, so as to avoid the difficulty in dislocating and closing the top of the bowl body 1 when the contact ring 14 is used, thereby improving the matching effect between the contact ring 14 and the top of the bowl body 1. A dislocation groove 16 located on the inner side of the outer ring 6 is provided on the top of the bowl body 1, and the bottom of the dislocation ring 15 is located inside the dislocation groove 16. When the dislocation ring 15 is used in conjunction with the bowl body 1, a space for the dislocation ring 15 to be plugged and dislocated with the top of the bowl body 1 is provided, so as to avoid the difficulty in plugging the dislocation ring 15 with the top of the bowl body 1 and dislocating the contact surface between the contact ring 14 and the top of the bowl body 1, thereby improving the dislocation plugging effect of the dislocation ring 15.
[0035] Reference Figure 2-Figure 4 In a preferred embodiment, a silicone ring 17 is fixedly connected to the bottom of the inner wall of the dislocation groove 16, and the top of the silicone ring 17 is in contact with the bottom of the dislocation ring 15. When the dislocation groove 16 is used in conjunction with the dislocation ring 15, contact sealing can be performed between the dislocation ring 15 and the dislocation groove 16 to avoid the situation where the dislocation groove 16 is difficult to seal when in use, thereby improving the sealing effect of the dislocation groove 16. Force-applying plates 18 are provided on the front and rear sides of the bowl body 1. The inner side of the force-applying plate 18 is fixedly connected to the outer side of the outer ring 6. When the outer ring 6 is used in conjunction with the bowl cover 3, a force-applying guide can be provided to the user to apply an upward opening force to the bowl cover 3 to avoid the situation where the bowl cover 3 is difficult to force open after closing the bowl body 1, thereby improving the convenience of opening the bowl cover 3.
[0036] Specifically, the working process or working principle of the water-leakage-proof plastic lunch box is as follows: when in use, the bowl cover 3 is moved to the top of the bowl body 1 by hand and a downward pressing and closing force is applied around the bowl cover 3. At this time, the closing ring 4 drives the leak-proof ring 5 to enter the dining cavity 2 and contact the inner wall of the dining cavity 2, and the bowl cover 3 and the bowl body 1 are initially closed and leak-proof. During this process, the top of the bowl body 1 enters the wrapping groove 13 and contacts the contact ring 14, and the bowl cover 3 and the bowl body 1 are secondarily closed and sealed. At the same time, the dislocation ring 15 enters the dislocation groove 16 at the top of the bowl body 1 and contacts the silicone ring 17, and the contact surface between the contact ring 14 and the bowl body 1 is thirdly plugged and dislocated and sealed. At this time, The outer ring 6 drives the slot 8 to move downward with the bowl cover 3. Since the outer ring 6 and the bowl cover 3 are both made of plastic material, when the top of the outer ring 6 contacts the top of the snap ring 9, the outer ring 6 is affected by the downward pressing force of the user, and is deformed to flip outward and staggered with the snap ring 9. When the outer ring 6 drives the slot 8 to wrap around the outside of the snap ring 9, the outer ring 6 resets to cooperate with the slot 8 and the snap ring 9 to close and tighten the bowl cover 3 and the bowl body 1 to ensure the closed sealing effect of the bowl cover 3 and the bowl body 1. At the same time, the reinforcement seat 10 cooperates with the closing ring 4 and the reinforcement plate 12 through the reinforcement rod 11 to perform closed reinforcement work between the bowl cover 3 and the bowl body 1, thereby reducing the deformation of the bowl body 1 after closing, and prompting the bowl cover 3 to better seal the bowl body 1.
