A plastic can for food packaging with good sealing performance includes: a can body 1;

[0022] A sealing cover 2 is slidably connected to the upper end of the can body 1. A filling port 3 is fixedly connected to the upper end of the can body 1. A rubber ring 4 is fixedly connected to the upper end of the filling port 3. Side grooves 5 are formed on the circumferential side of the can body 1, and two groups of side grooves 5 are provided. A clamping groove 6 is formed inside the side groove 5. A card 7 is fixedly connected to the bottom of the sealing cover 2, and two groups of cards 7 are provided. The card 7 is made of a material that is relatively hard and can self-recover after being bent and deformed, such as polypropylene, etc. A triangular block 8 is fixedly connected to the side of the card 7 close to the center of the sealing cover 2, and the triangular block 8 is matched with the clamping groove 6.

[0023] A dial 9 is slidably connected inside the side groove 5. A pressing block 10 is fixedly connected to the upper end of the dial 9, and the pressing block 10 is matched with the triangular block 8.

[0024] A limiting plate 11 is fixedly connected inside the side groove 5, and the pressing block 10 is slidably connected to the limiting plate 11.

[0025] A sliding groove 12 is formed through the upper end of the limiting plate 11, and the sliding groove 12 is matched with the pressing block 10.

[0026] A side plate 13 is fixedly connected to the front surface of the limiting plate 11. A sliding rod 14 is fixedly connected to the upper end of the dial 9, and two groups of sliding rods 14 are provided. The sliding rod 14 is slidably connected to the limiting plate 11.

[0027] A spring 15 is sleeved on the circumferential side of the sliding rod 14, and the spring 15 is located between the dial 9 and the limiting plate 11.

[0028] The working principle of a plastic can for food packaging with good sealing performance provided by the present utility model is as follows:

[0029] The first step: When in use, align the card 7 with the side groove 5 and then cover the sealing cover 2 on the upper end of the tank body 1. At this time, the sealing cover 2 covers the filling port 3. At the same time, the top of the inner wall of the sealing cover 2 contacts the rubber ring 4. Since the triangular block 8 is blocked by the circumferential side surface of the filling port 3 and the inner wall of the side groove 5, it will squeeze the card 7 outward to make the card 7 bend. At this time, pressing the sealing cover 2 forcefully can make the sealing cover 2 squeeze the rubber ring 4. At this time, the rubber ring 4 is squeezed and deformed. At the same time, the triangular block 8 can move downward due to the deformation of the rubber ring 4. After the triangular block 8 moves downward, it can be stuck into the card slot 6. At this time, the sealing cover 2 can tightly cover the upper end of the tank body 1, and the upper end of the filling port 3 can be sealed by squeezing the rubber ring 4. When removing the sealing cover 2, just buckle the two groups of cards 7 outward.

[0030] The second step: Dial the dial 9 upward. The dial 9 drives the extrusion block 10 to squeeze the triangular block 8 upward. At this time, the triangular block 8 is squeezed and drives the card 7 to bend outward toward the outside of the tank body 1. When the triangular block 8 slides out of the card slot 6, the sealing cover 2 can be removed. After releasing the dial 9, the dial 9 can be reset by the elastic force of the spring 15.

[0031] Compared with the related technology, a plastic tank for food packaging with good sealing performance provided by the present utility model has the following beneficial effects:

[0032] Align the card 7 with the side groove 5 and then cover the sealing cover 2 on the upper end of the tank body 1. At this time, the sealing cover 2 covers the filling port 3. At the same time, the top of the inner wall of the sealing cover 2 contacts the rubber ring 4. Since the triangular block 8 is blocked by the circumferential side surface of the filling port 3 and the inner wall of the side groove 5, it will squeeze the card 7 outward to make the card 7 bend. At this time, pressing the sealing cover 2 forcefully can make the sealing cover 2 squeeze the rubber ring 4. At this time, the rubber ring 4 is squeezed and deformed. At the same time, the triangular block 8 can move downward due to the deformation of the rubber ring 4. After the triangular block 8 moves downward, it can be stuck into the card slot 6. At this time, the sealing cover 2 can tightly cover the upper end of the tank body 1, and the upper end of the filling port 3 can be sealed by squeezing the rubber ring 4. When the plastic tank covers the sealing cover 2 well, it is not easy for the internal food to get damp, and it is easy to open. Dial the dial 9 upward. The dial 9 drives the extrusion block 10 to squeeze the triangular block 8 upward. At this time, the triangular block 8 is squeezed and drives the card 7 to bend outward toward the outside of the tank body 1. When the triangular block 8 slides out of the card slot 6, the sealing cover 2 can be removed. After releasing the dial 9, the dial 9 can be reset by the elastic force of the spring 15. Through this structure, it is convenient to remove the sealing cover 2.

[0033] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
