Description

Technical Field

[0001] The utility model relates to the technical field of plastic can products, in particular to a sealing cover structure for a plastic can. Background Art

[0002] Plastic jar sealing cap, commonly known as jar cap or bottle stopper, is an important component of plastic bottles. Its main function is to close the jar mouth and ensure that the liquid in the bottle will not leak due to external pressure, temperature changes or shaking.

[0003] Existing plastic jar sealing caps are usually screw caps or bottle stoppers. Screw caps will leave a gap between the cap and the jar body, reducing the sealing effect. If an annular leak-proof ring is set on the inner wall of the top of the plastic cap, the same problem as the bottle stopper will occur: when inserting and removing, due to the large friction between the cap and the inner wall of the jar body, it will be very difficult to pull the cap out of the jar body.

[0004] For this reason, we have designed a plastic jar sealing cover structure to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a sealing cover structure for a plastic jar to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides a plastic can sealing cover structure, including a can body, a can mouth fixedly provided in the middle of the top of the can body, an annular block fixedly provided on the outer wall surface of the can mouth, a plurality of grooves are opened inside the annular block, and a plurality of connecting plates are fixedly provided on the bottom of the annular block.

[0007] Furthermore, a tank cover is clamped on the top of the tank body, two annular limiting blocks are fixedly provided on the top of the tank body, a slot is provided between the two annular limiting blocks, and the top of the tank mouth is inserted into the slot.

[0008] Furthermore, a sliding groove is provided inside the connecting plate, and a plurality of protrusions are fixedly provided on the inner wall surface of the tank cover, and the protrusions are slidably inserted into the sliding groove.

[0009] Furthermore, a sealing ring is fixedly provided inside the annular limiting block, and the inner and outer surfaces of the bottom of the tank cover are in contact with one side surface of the sealing ring.

[0010] Furthermore, the top surface of the protrusion abuts against the bottom surface of the annular block.

[0011] Furthermore, the tank opening is placed inside the tank cover.

[0012] Compared with the prior art, the beneficial effect of the utility model is that by aligning the positions of the groove and the protrusion, and passing the protrusion through the groove, and then rotating the tank cover, the protrusion is slidably inserted into the interior of the slide groove. When the tank cover needs to be removed, it is only necessary to rotate the tank cover so that the groove and the protrusion correspond again, and pull the tank cover upwards. Whether covering or removing the tank cover, it can be done by rotating the tank cover and then pulling it out upwards or pressing the tank cover downwards, which facilitates the process of covering and removing the tank cover.

[0013] Compared with the prior art, the beneficial effect of the present invention is that by connecting the can lid to the top of the can body, the bottom of the can lid will be inserted into the slot, and the sealing ring inside the slot will abut against the inner and outer surfaces of the bottom of the can lid to seal the can body. The bottom of the can lid is inserted into the slot, which not only makes the entire can sealed, but also further increases the firmness of the connection between the can body and the can lid.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4The utility model provides a technical solution: a plastic can sealing cover structure, including a can body 1, a can mouth 5 is fixedly provided in the middle of the top of the can body 1, an annular block 6 is fixedly provided on the outer wall surface of the can mouth 5, a plurality of grooves 7 are provided inside the annular block 6, a plurality of connecting plates 8 are fixedly provided on the bottom of the annular block 6, a slide groove 9 is provided inside the connecting plate 8, a plurality of protrusions 10 are fixedly provided on the inner wall surface of the can cover 2, the protrusions 10 are slidably inserted in the slide groove 9, the top surface of the protrusion 10 is abutted against the bottom surface of the annular block 6, and the can mouth 5 is placed inside the can cover 2.

[0021] In specific implementation, when the tank cover 2 is placed on the top of the tank body 1, the groove 7 is first aligned with the position of the protrusion 10, and the protrusion 10 is passed through the groove 7. Then the tank cover 2 is rotated to slide the protrusion 10 into the interior of the slide groove 9. When the tank cover 2 needs to be removed, it is only necessary to rotate the tank cover 2 so that the groove 7 and the protrusion 10 are aligned again, and then pull the tank cover 2 upward.

[0022] It should be noted that the can body 1 and the can cover 2 here are both made of plastic material. Plastic material has good mechanical strength, is pressure-resistant and impact-resistant, is not easy to crack or deform, and has good heat resistance and can be used at a certain high temperature. At the same time, plastic has strong corrosion resistance and has good tolerance to various chemical substances such as acids, alkalis, and salts. It is not easy to be corroded and is suitable for storing various chemical reagents and cleaning agents. By using plastic material, the usable range of the can body 1 is increased.

[0023] See Figure 1-4 As shown, the top of the can body 1 is clamped with a can cover 2, and two annular limit blocks 3 are fixed to the can body 1. A slot 4 is provided between the two annular limit blocks 3, and the top of the can mouth 5 is inserted into the slot 4. A sealing ring is fixed inside the annular limit block 3, and the inner and outer surfaces of the bottom of the can cover 2 are in contact with one side surface of the sealing ring.

[0024] In specific implementation, after the can lid 2 is connected to the top of the can body 1, the bottom of the can lid 2 will be inserted into the slot 4, and the sealing ring inside the slot 4 will abut against the inner and outer surfaces of the bottom of the can lid 2 to seal the can body 1. The bottom of the can lid 2 is inserted into the slot 4, which not only makes the entire can sealed, but also further increases the firmness of the connection between the can body 1 and the can lid 2.

[0025] It should be noted that the sealing ring will fill the gaps between the bottom of the can cover 2 and the top of the can body 1, and between the inner and outer side surfaces of the can cover 2 and the inner wall of the annular limit block 3 through its elasticity. When the can cover 2 is covered on the top of the can body 1, the sealing ring ensures sufficient sealing between the can body 1 and the can cover 2 as a whole.

[0026] Working principle: When putting the can cover 2 on the top of the can body 1, first align the groove 7 with the position of the protrusion 10, and make the protrusion 10 pass through the groove 7, then rotate the can cover 2 to make the protrusion 10 slide and insert into the inside of the slide groove 9. When the can cover 2 needs to be removed, just rotate the can cover 2 to make the groove 7 and the protrusion 10 correspond again, and pull the can cover 2 upward.

[0027] After the can lid 2 is connected to the top of the can body 1, the bottom of the can lid 2 will be inserted into the slot 4, and the sealing ring inside the slot 4 will abut against the inner and outer surfaces of the bottom of the can lid 2 to seal the can body 1. The bottom of the can lid 2 is inserted into the slot 4, which not only makes the entire can sealed, but also further increases the firmness of the connection between the can body 1 and the can lid 2.
