[0035] The embodiment of the present application discloses a sealing cover.
[0036] Reference Figure 1 and Figure 3 , comprising a cover seat 2 and a cover body 1 rotatably arranged thereon, the cover seat 2 being detachably arranged on the mouth of the sealed container; the cover seat 2 and the cover body 1 being connected by a locking member 3; wherein the locking member 3 comprises a locking piece 311 and a clamping block 3111, the locking piece 311 being rotatably arranged on the cover seat 2, a groove 4 matching the shape and size of the locking piece 311 being provided on the cover body 1, the clamping block 3111 being integrally formed on the locking piece 311, and a clamping block 3111 matching the shape and size of the clamping block 3111 being provided in the groove 4 The cover base 2 and the cover body 1 are locked by the locking piece 3, so that the cover base 2 and the cover body 1 fit tightly, improving the sealing of the container mouth; when unpacking and using, the locking piece 311 is easily turned over manually to release the buckling and clamping restriction of the cover body 1 and the cover base 2, thereby opening the opening of the cover base 2, simplifying the operation during installation and unpacking; after the cover base 2 and the container can are sealed with each other, the cover body 1 and the cover base 2 are further buckled and sealed to ensure a good seal inside the container can;
[0037] See also Figure 6As shown, an anti-theft structure 101 is also installed on the cover body 1. The anti-theft structure 101 is connected to the inner side wall of the groove 4 through a bridging point 102. When opening the cover body 1, it is necessary to first break the connection point between the cover body 1 and the anti-theft structure 101, and then release the buckling connection structure between the locking piece 311 and the cover body 1. Once the bridging point 102 is damaged, it cannot be restored, which helps to warn others and enables others to understand the state of the cover body 1 and the product inside, and helps to improve the credibility of the seller and the consumer experience.
[0038] See Figure 1 and Figure 4 As shown, a first convex block 312 is integrally formed on the locking piece 311, and a second convex block 321 is integrally formed on the inner side wall of the groove 4. When the locking piece 311 is closed into the groove 4, the first convex block 312 and the second convex block 321 are buckled with each other. When the locking piece 311 is flipped and closed into the groove 4, the first convex block 312 and the second convex block 321 are交错扣合 (interleaved and buckled). The locking piece 311 is L-shaped. The first convex blocks 312 are located on both sides of the end face of the locking piece 311, and there are two first convex blocks 312. The second convex block 321 is arranged at a certain height from the bottom wall of the groove 4, and there are two second convex blocks 321. When the second convex block 321 and the first convex block 312 are buckled with each other, the end face of the cover body 1 and the end face of the locking piece 311 are in the same plane, ensuring complete buckling and sealing.
[0039] See Figure 4 As shown, a limiting plate 313 for leaving a reserved gap with the groove 4 is also installed on the locking piece 311. The limiting plate 313 is integrally formed with the locking piece 311. A barb 314 is integrally formed at one end of the first convex block 312 away from the locking piece 311. The limiting plate 313 is in a "凵" shape. When the locking piece 311 is buckled in the groove 4, it can be掰开 (opened) through the reserved gap between the locking piece 311 and the groove 4, which is convenient for unsealing the cover body 1.
[0040] See Figure 3 As shown, a rib 5 is also integrally formed on the cover body 1, and a pit 6 adapted to the rib 5 is formed on the locking piece 311. When the locking piece 311 is buckled on the groove 4, the rib 5 abuts against the pit 6. A rib 7 is integrally formed on the cover base 2, and a through groove 8 adapted to the rib 7 is formed on the cover body 1. When the cover body 1 and the cover base 2 are closed, the rib 7 is buckled in the through groove 8. The cover body 1 and the cover base 2 are cross-locked, which improves the stability and firmness of the overall structure when closed, preventing the gap between the cover body 1 and the cover base 2 in the sealed state from affecting the food in the container tank.
[0041] See Figure 2 As shown, a fitting table 9 is formed on the end face of the cover base 2 close to the cover body 1, and an inner concave area 10 adapted to the fitting table 9 is formed on the end face of the cover body 1 close to the cover base 2. The inner concave area 10 is in a ring-shaped concave shape and cooperates with the convex part of the fitting table 9, which is convenient for positioning and clamping during the installation process and improves the sealing effect of the overall structure.
[0042] See also Figure 2 and Figure 5 As shown, the spoon 11 can be detachably mounted on the cover seat 2, and a locking block 12 for clamping the spoon 11 is integrally formed on the inner side of the cover body 1. An abutment member for limiting the falling of the spoon 11 is also installed on the cover seat 2. Two locking blocks 12 are provided on the inner side of the cover body 1. The locking blocks 12 are made of elastic material. When the spoon 11 is removed from the cover seat 2 and placed on the cover body 1, the locking blocks 12 can clamp the middle part of the spoon 11, and at the same time, the abutment member 13 is used to abut the end of the spoon 11 to prevent it from falling into the container.
[0043] See also Figure 5 As shown, the abutment member includes an abutment ring 131 and an abutment block 132. The abutment ring 131 / abutment block 132 and the inner side wall of the cover 2 are integrally formed. The abutment block 132 / abutment ring 131 and the two ends of the spoon 11 are tightly pressed against each other. There are two groups of abutment members. The positions for placing the spoon 11 formed by the two groups of abutment members and the positions for placing the spoon 11 on the cover 2 when packaging are perpendicular to each other, so that the spoon 11 is located at different positions when packaging and when placing, so as to prevent interference between the placing position and the packaging installation position. When the spoon 11 is placed between the locking blocks 12 on the inner side of the cover 1, the bottom of the spoon 11 and the abutment blocks 132 on both sides of the inner wall of the cover 2 abut against each other. If the spoon 11 located in the cover 1 is loose or falling, the area formed by the abutment ring 131 further abuts against the spoon 11 to prevent the spoon 11 from falling further into the container.
[0044] The implementation principle of a sealing lid in the embodiment of the present application is as follows: the container mouth and the cover seat 2 are locked by means of threads or buckles, the locking piece 311 in the groove 4 is manually pried, the first protrusion 312 and the second protrusion 321 are buckled with each other to release the restriction, so that the locking piece 311 in the groove 4 is turned at least 180 degrees, the turning part connected between the cover body 1 and the cover seat 2 is turned 90 degrees to 180 degrees, and the installed spoon 11 in the cover seat 2 can be torn off manually. When not in use, the spoon 11 is clamped between the two lock buckles, and the bottom of the spoon 11 is overlapped and abutted with the abutment block 132 and the abutment ring 131; after the container is used, the cover seat 2 and the cover body 1 are closed together, the locking piece 311 is turned into the groove 4, and after the first protrusion 312 and the second protrusion 321 are buckled with each other, the end face of the locking piece 311 is flush with the end face of the cover body 1, which is completely sealed and maintains good sealing; the connection method of the lock fastener 3 makes it easier and more convenient to open and close the can cover.
