Description

Technical Field

[0001] The invention relates to the field of can lids, in particular to a resealable can lid and a use method thereof. Background Art

[0002] In the can packaging sector, traditional lid designs primarily focus on one-time opening, meaning once opened, they cannot be effectively resealed. These designs rely on pull tabs or tear-off mechanisms, allowing users to open the can and consume the liquid by pulling the tab or tearing a specific area. These lids are widely used in the food and beverage industries, meeting basic opening and drinking needs.

[0003] However, there are defects in the can lids in the prior art. Traditional can lids usually do not have the ability to be re-sealed. Once opened, the sealing inside the can cannot be ensured again, which can easily cause the remaining liquid to leak during storage or carrying, causing inconvenience and waste. At the same time, due to the lack of re-sealing function, when users cannot drink the liquid in the can at one time, they often need to find other containers to store the remaining liquid, which not only increases the cost of use, but may also affect the quality and taste of the liquid.

[0004] Therefore, we propose a resealable can lid, which realizes the resealable function and effectively solves the leakage problem caused by the failure of traditional cans to seal after opening. At the same time, the integrated anti-theft structure improves safety and optimizes the user experience. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a resealable can lid and a method of use thereof, so as to solve the problem that the current traditional can lid usually does not have the ability to be re-sealed. Once opened, the sealing inside the can cannot be ensured again, which easily causes the remaining liquid to leak during storage or carrying, causing inconvenience and waste. At the same time, due to the lack of re-sealing function, when the user cannot drink the liquid in the can at one time, he often needs to find other containers to store the remaining liquid, which not only increases the cost of use, but may also affect the quality and taste of the liquid.

The sealing ring 11 installed on the top of the sealed chassis 1 fits the aluminum cover 2 to form a seal.

[0048] For details, see Figure 1 A bending portion 41 to prevent breakage is provided in the middle of the top cover 4 .

[0049] For further information, see Figure 1 , the top cover 4 can slide along the sliding groove 22 to the direction of the anti-drop pin 42 at the top of the drinking port 21 on the surface of the aluminum cover 2.

[0050] It is worth noting that, see Figure 3The broken anti-theft part 3 and the second riveted column 12 of the sealed chassis 1 are hot-pressed and locked to form an anti-theft structure.

[0051] It is worth noting that see Figure 3 When the anti-dropout pin 42 at the bottom of the top cover 4 is inserted into the anti-dropout pin 42 through hole 24 on the surface of the aluminum cover 2, the top cover 4 is restricted from sliding. After being pulled out, the top cover 4 is allowed to move along the sliding groove 22.

[0052] A method for using a can lid is also provided, comprising an assembly step, a use step, and a resealing step. The assembly step comprises:

[0053] S1. Insert the first rivet post 43 of the top cover 4 through the sliding slot 22 of the aluminum cover 2 and hot-press rivet the first rivet point 51 and the second rivet point 54 of the locking member 5.

[0054] S2. Slide the top cover 4 to the direction of the anti-dropout pin 42 at the top of the drinking spout 21, so that the first locking groove 14 and the second locking groove 13 of the sealing bottom plate 1 are slidably engaged with the first locking point 52 and the second locking point 53 of the locking member 5;

[0055] S3. Slide the entire plastic part toward the drinking port 21. The second rivet column 12 of the sealed chassis 1 passes through the rivet hole 23 of the aluminum cover 2 and is hot-pressed and locked with the broken anti-theft part 3. The sealing ring 11 fits the aluminum cover 2 to form a seal.

[0056] It is worth mentioning that see Figure 4 , the usage steps include:

[0057] S1, pull up the top cover 4, pull out the anti-drop pin 42 and trigger the breakage anti-theft element 3 to take effect;

[0058] S2. Then, pull the top cover 4 in the direction of the arrow to deform the sealing bottom plate 1 to form a water flow gap, and the liquid flows out from the drinking port 21.

[0059] It is worth emphasizing that see Figure 5 , the resealing steps include:

[0060] S1. Push the top cover 4 in the opposite direction of the arrow to the locking position;

[0061] S2. The first locking point 52 and the second locking point 53 of the locking member 5 are re-engaged with the first locking groove 14 and the second locking groove 13 of the sealing chassis 1;

[0062] S3. Insert the anti-drop pin 42 to fix the top cover 4.

[0063] During assembly, the first rivet post 43 of the top cover 4 is first inserted through the sliding groove 22 of the aluminum cover 2 and hot-pressed with the first and second rivet points 54 of the locking member 5. The top cover 4 is then slid toward the anti-dropout pin 42 at the top of the drinking spout 21, so that the first and second locking grooves 13 of the sealing chassis 1 slide and engage with the first and second locking points 53 of the locking member 5. Finally, the entire plastic part is slid toward the drinking spout 21, so that the second rivet post 12 of the sealing chassis 1 is inserted through the riveted hole 23 of the aluminum cover 2 and hot-pressed with the breakage anti-theft member 3 to complete the assembly. During use, the user pulls up the top cover 4, the anti-dropout pin 42 is pulled out, and the breakage anti-theft member 3 is activated. Continuing to pull the top cover 4 causes the sealing chassis 1 to deform, forming a water flow gap, and liquid flows out of the drinking spout 21. When resealing, push the top cover 4 in the opposite direction to the locking position so that the first and second locking points 53 of the locking member 5 are re-engaged with the first and second locking grooves 13 of the sealing bottom plate 1, and insert the anti-drop pin 42 to fix the top cover 4 to restore the seal.

[0064] This embodiment realizes the repeated sealing function of the can by sliding and locking the top cover 4, the locking piece 5 and the sealing bottom plate 1, effectively preventing liquid leakage; at the same time, the hot-pressed locking structure of the broken anti-theft piece 3 and the sealing bottom plate 1 provides an anti-theft warning function.
