Abstract
Description
Technical Field
[0001] This utility model relates to the field of food packaging can technology, specifically an aluminum food packaging can that is pressure-resistant and easy to open. Background Technology
[0002] Aluminum food packaging cans are widely used in the food packaging industry due to their lightweight material and excellent barrier properties, effectively preventing the influence of external oxygen and moisture on food quality. They are commonly used for packaging various foods such as nuts, biscuits, and canned meat. The core requirement for this type of packaging can is to ensure the airtightness of the food during storage, while also ensuring ease of opening to enhance the user experience.
[0003] However, existing aluminum food packaging cans have certain structural design flaws. Firstly, the sealing caps of existing cans are mostly connected to the can body only through the edge, without a sealing plug at the bottom of the cap to fit inside the can body, leaving the can opening without effective support. During transportation or storage, if subjected to external pressure, the can opening is easily deformed, causing the food inside to break under pressure and failing to ensure its integrity. Secondly, the sealing strips of existing cans typically only have a simple tear-off end. When the can is stored for a long time, the adhesion between the sealing strip and the can body / cap increases, requiring significant force for users to tear the sealing strip, making it inconvenient and difficult to open the can. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an aluminum food packaging can that is pressure-resistant and easy to open, thereby solving the problems mentioned in the background art, such as the can opening being easily deformed, causing the food inside the can to break under pressure, failing to ensure the integrity of the food, and the packaging can being difficult to open.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum food packaging can that is pressure-resistant and easy to open, comprising: A can cylinder, wherein a sealing cap is installed on the upper surface of the can cylinder, and a sealing plug is installed at the bottom of the sealing cap; A sealing strip is provided at the connection between the can cylinder and the sealing cap. The tear-off end of the sealing strip is provided with a rotating rod, and the surface of the rotating rod is covered with a connecting plate. A connecting block is disposed on the surface of a connecting plate, and a mating block is movably mounted on the surface of the connecting block, the mating block being connected to the tear-off end of a sealing strip; A sealing gasket is provided on the inner wall of the sealing strip, and pull rings are installed at both ends of the rotating rod.
[0006] Preferably, the docking block has a U-shaped design, and the connecting block is installed in the inner cavity of the docking block via a rotating shaft, so that the docking block and the connecting block can rotate flexibly, which is convenient for operation when opening the packaging can. In addition, the U-shaped structure can better adapt to and connect with the tear end of the sealing strip, enhancing the stability of the connection.
[0007] Preferably, the upper surface of the sealing cap is provided with an installation groove, and a handle is installed on the inner wall of the installation groove via a rotating shaft. The design of the rotating shaft allows the handle to be retracted into the installation groove when not in use, reducing space occupation and preventing the handle from protruding and affecting the stacking and storage of the packaging cans.
[0008] Preferably, an installation ring is installed at the opening of the can, and the installation ring is inserted into the gap between the sealing cap and the sealing plug. The installation ring plays a role in positioning and assisting in sealing, so that the sealing cap fits better with the can, enhances the sealing effect, prevents food from getting damp or deteriorating, and also helps to improve the overall strength of the packaging can.
[0009] Preferably, a limiting strip is installed on the surface of the rotating rod. The limiting strip is embedded in the inner side of the connecting plate. The limiting strip can prevent the rotating rod from excessive displacement during rotation, ensuring that the rotating rod rotates within a suitable range. This makes the tearing operation of the sealing strip more stable and reliable, and avoids damage to the sealing strip or failure to tear it properly due to improper movement of the rotating rod.
[0010] Preferably, a sealing groove is provided at the connection between the can and the sealing cap, and the sealing strip is installed inside the sealing groove. The sealing groove provides a dedicated installation position for the sealing strip, so that the sealing strip can fit more tightly between the can and the sealing cap, further enhancing the sealing performance and effectively preventing external air, moisture and other substances from entering the packaging can, thus ensuring the quality and safety of the food.
[0011] Compared with the prior art, this utility model provides an aluminum food packaging can that is resistant to pressure damage and easy to open, and has the following beneficial effects: This pressure-resistant and easy-to-open aluminum food packaging can features a sealing plug that effectively fits inside the can, initially improving its sealing performance. This prevents direct contact between the food inside and the external environment and reduces the risk of deformation of the can opening due to pressure, thus preventing pressure damage and protecting the food from crushing. By pulling the pull ring, the rotating rod moves, which in turn moves the connecting plate and the mating block, easily tearing the sealing strip from the connection between the can and the sealing cap. If the sealing strip is difficult to tear due to prolonged storage, it can be slowly rolled up by rotating the rotating rod, achieving easy opening of the packaging can. Attached Figure Description

Figure 5 Pull rings 7 are installed at both ends of the rotating rod 5.
[0016] A sealing cap 2 is installed on the upper surface of the can 1, and a sealing plug 3 is installed at the bottom of the sealing cap 2. The sealing plug 3 can effectively fit with the inside of the can 1, initially improving the sealing performance of the packaging can and preventing the food inside the can from directly contacting the external environment. A sealing strip 4 is set at the connection between the can 1 and the sealing cap 2, and a sealing gasket 6 is provided on the inner wall of the sealing strip 4. The sealing strip 4 and the sealing gasket 6 cooperate with each other to further enhance the sealing effect between the can 1 and the sealing cap 2, reduce the entry of external moisture, dust, etc. into the can, and better protect the quality of the food. A rotating rod 5 is provided at the tear-off end of the sealing strip 4. The surface of the rotating rod 5 is covered with a connecting plate 51. A docking block 53 is movably installed on the surface of the connecting plate 51 and is connected to the tear-off end of the sealing strip 4. Meanwhile, pull rings 7 are installed at both ends of the rotating rod 5. Pulling the pull rings 7 can drive the rotating rod 5 to move. The rotating rod 5 drives the connecting plate 51 and the docking block 53 to move together, thereby easily tearing the sealing strip 4 from the connection between the can cylinder 1 and the sealing cap 2, achieving an easy-to-open effect for the packaging can. If the sealing strip 4 is difficult to tear due to the packaging can being stored for too long, the sealing strip 4 can be slowly rolled up by rotating the rotating rod 5, thus making it easy to open the sealing cap 2. In addition, the aluminum can cylinder 1 itself has a certain structural strength. With the support of the sealing cap 2 and the sealing plug 3, it can resist external pressure to a certain extent, reducing the deformation of the can body due to pressure, thereby playing a role in preventing pressure damage and protecting the food inside the can from being squeezed and damaged.
[0017] The mating block 53 has a U-shaped design, and the connecting block 52 is installed in the inner cavity of the mating block 53 through a rotating shaft, so that the mating block 53 and the connecting block 52 can rotate flexibly, which is convenient for operation when opening the packaging can.

The inner wall of the installation groove 8 is equipped with a handle 81 via a rotating shaft. The design of the rotating shaft allows the handle 81 to be retracted into the installation groove 8 when not in use, reducing space occupation and preventing the handle 81 from protruding and affecting the stacking and storage of the packaging cans.
[0019] Please see Figure 3 An installation ring 9 is installed at the opening of the can 1. The installation ring 9 is inserted into the gap between the sealing cap 2 and the sealing plug 3. The installation ring 9 plays a role in positioning and assisting in sealing, so that the sealing cap 2 fits better with the can 1, enhances the sealing effect, prevents food from getting damp or deteriorating, and also helps to improve the overall strength of the packaging can.
[0020] Please see Figure 5A limiting strip 10 is installed on the surface of the rotating rod 5. The limiting strip 10 is embedded in the inner side of the connecting plate 51. The limiting strip 10 can prevent the rotating rod 5 from excessive displacement during rotation, ensuring that the rotating rod 5 rotates within a suitable range, thereby making the tearing operation of the sealing strip 4 more stable and reliable, and avoiding damage to the sealing strip 4 or failure to tear it properly due to improper movement of the rotating rod 5.
[0021] Please see Figure 3 A sealing groove 11 is provided at the connection between the can cylinder 1 and the sealing cap 2. The sealing strip 4 is installed inside the sealing groove 11. The sealing groove 11 provides a special installation position for the sealing strip 4, so that the sealing strip 4 can fit more tightly between the can cylinder 1 and the sealing cap 2, further enhancing the sealing performance and effectively preventing external air, moisture and other substances from entering the packaging can, thus ensuring the quality and safety of food.
