Description
Technical Field
[0001] This utility model relates to the field of easy-open can technology, specifically a high-rolled edge easy-open can. Background Technology
[0002] Aluminum cans are sealed containers made of metal (aluminum or tinplate) or composite materials. Their core innovation lies in the easy-open lid design on the top—through pre-compression scoring lines, riveted pull rings, and a lever-based mechanical structure, they can be opened quickly and without damage with one hand, while ensuring absolute airtightness during transportation and storage. This packaging technology originated in the mid-20th century, initially featuring "fully peelable pull rings," but due to environmental concerns, it gradually evolved into "retained pull rings" (the pull ring is connected to the lid). It is widely used in beverages (such as carbonated drinks and beer) and food (such as eight-treasure porridge), and has advantages such as lightweight, strong pressure resistance, and recyclability. It has also spawned improved forms such as straw fixing and double pull ring foam control, becoming one of the iconic solutions in the modern fast-moving consumer goods industry.
[0003] Patent application CN202320194775.1 discloses a concealed spout can, which "includes a can body and a pull ring, the can body is provided with a can lid, the can lid is connected to the pull ring, the can lid is provided with a fixing member on the side near the can body, the fixing member is provided with a spout, the spout includes a suction part and a float, the float is provided with a retaining ring, the suction part is provided with a through hole near the float, the fixing member includes a fixing ring, the fixing ring is provided with a limiting post, the limiting post is connected to the can lid, and the limiting post is provided with a [missing information - likely a typo, should be "likely referring to a specific feature or design] near the can lid." The recessed part has a carrier piece on the fixing ring. This device not only keeps the can aesthetically pleasing but also prevents consumers from contacting the can surface when drinking, making it healthy, safe, and fun, attracting consumers. Based on the above patent search and combined with the existing high-rolled edge cans, it was found that the existing high-rolled edge cans use a compressed pull ring structure. In the process of opening the can, users need to use their fingernails or even their fingertips to pry up the pull ring to pull the lid. For users without protruding nails or those who have manicured nails, opening the lid is very inconvenient. Even some users with protruding nails may damage their nails when prying the pull ring. Based on this, the present invention designs a high-rolled edge easy-open can to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a high-rolled edge easy-open can to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-rolled edge easy-open can includes a can body, with a lid fixedly installed at the upper end of the can body. The lid is provided with a lever mechanism and a pull ring mechanism. The lever mechanism includes a lower pressure pad, a lever body, a mounting groove, a support rod, a rotating sleeve, a limit socket, a first limit plate, a second limit plate, an inner groove, and a receiving sleeve. The mounting groove is formed in the middle of the can lid, and the support rod is fixedly installed on the inner wall of the mounting groove. A rotating sleeve is sleeved on the outside of the support rod, and the upper end of the rotating sleeve is fixedly connected to the limit socket. The lever body is movably inserted into the slot of the limit socket. The lower pressure pad is fixedly connected to the rear end of the lever body. The middle part of the lever body is provided with a first limiting plate and a second limiting plate with a spacing. The first limiting plate is located behind the limiting socket, and the second limiting plate is located in front of the limiting socket. The front end of the lever body has an inner groove that is inserted into the receiving sleeve. The inner wall of the receiving sleeve is provided with a protrusion that engages with the inner groove. The pull ring mechanism includes an easy-open cover, a mounting rod, a mounting sleeve, and a pull ring. The receiving sleeve is fixed to the upper surface of the easy-open cover. The front end of the receiving sleeve is connected to the mounting rod. The mounting sleeve is fitted on the outside of the mounting rod. The front end of the mounting sleeve is fixedly connected to a pull ring that can rotate around the mounting rod.
[0006] Optionally, the receiving sleeve is fixed to the upper surface of the easy-open cover by welding, and the mounting rod is integrally formed and connected to the front end of the receiving sleeve.
[0007] Optionally, the distance between the first limiting plate and the second limiting plate of the lever body is equal to the axial width of the limiting socket, thus forming a movement limiting structure for the lever body.
[0008] Optionally, the inner groove at the front end of the lever body is a plurality of rectangular grooves spaced apart along the axial direction, and the protrusion on the inner wall of the receiving sleeve is a wedge-shaped protrusion that matches the groove.
[0009] Optionally, the connection between the mounting sleeve and the mounting rod is provided with an annular hinge structure, allowing the pull ring to rotate around the axis of the mounting rod.
[0010] Optionally, the lever portion behind the limiting socket constitutes a power arm, and the lever portion in front of the limiting socket constitutes a resistance arm, with the length of the power arm being twice the length of the resistance arm.
[0011] Optionally, the support rod is a cylindrical metal rod, and the inner diameter of the rotating sleeve is 0.1-0.3 mm larger than the diameter of the support rod to form a clearance fit.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a lever mechanism is provided. The lever system composed of the lever body and the limiting socket significantly reduces the force required to open. The ratio of the power arm to the resistance arm (2 times) allows users with short nails or those who have manicures to complete the opening action by simply pressing down on the pressure pad, avoiding the risk of nail damage caused by traditional prying rings. The meshing structure of the inner groove body and the inner protrusion of the receiving sleeve ensures the stability of the applied force and prevents slippage. The gap fit between the support rod and the rotating sleeve allows the lever body to be finely adjusted in angle to adapt to different users' pressing habits. The bidirectional limiting of the first limiting plate and the second limiting plate prevents the lever body from failing due to excessive displacement.
[0013] 2. In this utility model, a pull ring mechanism is provided. The pull ring mechanism is designed to rotate around the axis through the rotating connection between the mounting sleeve and the mounting rod, which completely eliminates the problem of squeezing the skin of the fingers due to the fixed angle of the traditional pull ring. The fixed connection between the easy-open cap and the receiving sleeve ensures that the opening action is directly transmitted to the weak point of the cap, improving the opening efficiency. The flexible rotation characteristics of the pull ring also make it easy for users to adjust the direction of force according to the grip posture, further reducing the difficulty of operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-10In this embodiment of the present invention, a high-rolled edge easy-open can includes a can body 1, a can lid 2, a lever mechanism 3, and a pull ring mechanism 4. The can lid 2 is fixed to the upper end of the can body 1 by a rolled edge sealing process. An installation groove 303 is formed in the middle of its surface. A cylindrical support rod 304 is welded in the installation groove 303. A rotating sleeve 305 is sleeved on the outside of the support rod 304. The inner diameter of the rotating sleeve 305 is 0.1-0.3mm larger than that of the support rod 304 to form a clearance fit, ensuring that the rotating sleeve 305 can rotate around the axis of the support rod 304. A limit socket 306 is installed on the upper end of the rotating sleeve 305. A slot is formed in the middle of the limit socket 306. The width of the slot is the same as that of the lever. The lever body 302 has a matching thickness and is a long strip-shaped metal sheet structure. The rear end of the lever body 302 is welded with a lower pressure pad 301. The middle part is stamped with a first limiting plate 307 and a second limiting plate 308. The distance between the two limiting plates is equal to the axial width of the limiting socket 306, which is used to limit the movement range of the lever body 302 in the slot. The front end of the lever body 302 has multiple rectangular inner grooves 309 that are spaced apart along the axial direction to form a tooth structure, which is inserted into the receiving sleeve 310 by plugging. The receiving sleeve 310 is a ring-shaped metal part, and its inner wall is stamped with wedge-shaped protrusions that fit the inner grooves 309. The bottom of the receiving sleeve 310 is fixed to the upper surface of the easy-open cover 401 by welding.
[0020] In the pull ring mechanism 4, the easy-open cover 401 is connected to the can cover 2 through the pre-indentation line. The front end of the receiving sleeve 310 is integrally formed with the mounting rod 402. The mounting sleeve 403 is sleeved on the outside of the mounting rod 402. The mounting sleeve 403 is connected to the pull ring 404 through a ring-shaped hinge structure, so that the pull ring 404 can rotate around the axis of the mounting rod 402.
[0021] The working principle of this utility model is as follows: The high-rolled edge easy-open can achieve effortless opening through the linkage of the lever mechanism 3 and the pull ring mechanism 4. When the user operates, pressing down the pressure pad 301 causes the rear end of the lever body 302 to move downward, forming a lever structure with the limit socket 306 as the fulcrum. The length of the power arm (the part behind the limit socket 306) is greater than that of the resistance arm (the part in front of the limit socket 306), so that the front end of the lever body 302 prys the receiving sleeve 310 upward through the engagement of the inner groove body 309 and the inner protrusion of the receiving sleeve 310. Fixed to the surface of the easy-open can 401, the lever 401 is separated from the can lid 2 when subjected to force. After opening, the user can rotate the pull ring 404 to unfold it around the axis of the mounting rod 402, avoiding the finger pressing problem of traditional easy-open cans. During this process, the first limiting plate 307 and the second limiting plate 308 limit the range of movement of the lever body 302. The clearance fit between the support rod 304 and the rotating sleeve 305 ensures the flexibility of the lever action. The multi-stage tooth design of the inner groove 309 provides segmented force support for the continuous prying of the easy-open can 401.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
