[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme: A full opening easy open end with high strength single safety edge, comprising a cover body and a pull ring arranged on the cover body; The cover body comprises: a cover surface; an expansion ring arranged on the cover surface; a finger platform arranged on the cover surface and located below the opening area of the pull ring, forming a convex-concave structure with the expansion ring, used for maintaining the tension and strength of the cover surface; a convex-concave shoulder surface arranged on the edge of the cover surface and located in the contact area with the can opening, having a convex-concave structure, the convex-concave structure is formed by forward and reverse folding, having R1 angle and R2 angle in the forward and reverse directions and two inclined angles of alpha and delta; a countersunk rib arranged on the cover surface, one end of which is connected with the convex-concave shoulder surface; an embedded ring platform, one end of which is connected with the other end of the countersunk rib, and the other end is connected with the cover surface, having an inclined angle beta and an R3 angle, improving the strength of the tongue on the cover surface; The two inclined angles of alpha and delta improve the pressure resistance of the cover surface together with the countersunk rib.

[0006] Preferably, a folding safety edge is further arranged on the cover body, the folding safety edge is formed into a Z-shaped folding shape by folding the cover surface, and the folding safety edge has a space shielding relationship with the score line, so that the sharp edge of the opening is not easy to cut the user when the cover surface is opened.

[0007] Preferably, a bird flying scale is further arranged on the cover body, the bird flying scale is arranged below the pull ring and close to the rivet on the cover body, and the bird flying scale is used to break the bird flying scale by the pull ring and the rivet first when the pull ring is pulled, so that the pressure in the can is released, the tongue is prevented from flying to hurt people, and the bird flying scale serves as the first score line for opening the cover surface of the cover body.

[0008] Preferably, the center arc area score line of the bird flying scale is 0.1-0.9 mm away from the edge of the rivet on the cover body.

[0009] Preferably, the cover body further comprises the following arranged on the cover surface thereof: a ring-shaped main score line, which serves as the main score line for opening the cover surface of the cover body, and ensures that the cover surface can be fully opened to meet the full opening requirement; a ring-shaped rivet arranged on the cover surface of the cover body and directly contacting the pull ring, for supporting the pull ring; a cover supporting rivet arranged on the cover surface of the cover body and located on both sides of the pull ring, for supporting the cover surface to be flat and limiting the rotation of the pull ring; a rivet arranged on the cover surface of the cover body, as a connecting point of the cover surface and the pull ring; a hook edge, as an outer diameter part of the cover body, cooperating with the can body to participate in double seaming to meet the sealing requirement of the can end; a tongue arranged on the cover surface and located inside the main score line, directly associated with the main score line, for tearing along the score line track when the cover surface is opened, and finally completely opening the cover surface.

[0011] The high-strength single safety edge full opening easy-open cover provided by the application has the following beneficial effects compared with the prior art: (1) High strength and excellent pressure resistance: Through the precise combination and synergistic effect of various structural elements such as "convex-concave structure (integrated expansion ring and finger platform)" "convex-concave shoulder surface" "counter sunk rib" and "embedded ring platform", a three-dimensional and enhanced stress frame is constructed on the cover surface. This unique composite structure design significantly improves the stiffness and pressure resistance of the cover surface, effectively resisting deformation, bulging or indentation caused by internal pressure (such as pressure generated by carbonated beverages) or external pressure (such as stacking, collision), and improving the deformation resistance.

[0012] (2) High efficiency of material saving (material thinning / lightweighting): The significant strengthening effect brought by the ingenious and powerful pressure-resistant structure design allows the material thickness of the cover to be reduced while meeting the same or even higher pressure resistance requirements. This material thinning directly reduces the weight of the metal sheet (such as aluminum and tin-plated iron) required to produce each easy-open lid, achieving significant lightweighting.

[0019] (4) Optimizing the use experience, facilitating direct drinking: the full opening design enables the lid to be completely opened or removed, forming a large aperture opening, combined with the folding safety edge, ensuring smooth and unobstructed drinking process. No additional tools or liquid pouring is required, saving time and effort, especially suitable for immediate drinking needs in outdoor activities, after exercise or fast-paced life. The direct drinking experience is more comfortable, the lid does not block the flow of beverages, reduces liquid spilling problems, and improves user satisfaction. (5) Bird flying scale line, when opened, the bird flying scale line releases the pressure in the tank first, preventing injury from flying tongue.

[0020] In summary, the present application solves the technical problem of easy cutting of traditional easy-open lids during direct drinking through the combination of "folding safety edge + full opening".

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings of the embodiments of the present application; Obviously, the described embodiments are only a part of the embodiments of the present application; rather than all embodiments, based on the embodiments in the present application; all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

In addition, the terms "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "sleeved / connected", "connected" and the like should be broadly understood, for example, "connected" can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, and can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] As Figures 1-4 shown, the present application provides a high-strength single safety edge full-opening easy-open cover, comprising a cover body 1 and a pull ring 2 arranged on the cover body 1. The cover body 1 is usually made of metal material and has a circular profile. The pull ring 2 is connected to the edge of the cover body 1 by a fixing device such as a rivet 110 or a buckle, which is convenient for the user to pull to open the cover. The full-opening structure allows the cover to be completely removed, facilitating the quick removal and filling of the contents. Among them, the cover body 1 and the pull ring 2 can be selected as conventional cover body 1 and pull ring 2 in the art, for example, a standard aluminum alloy cover body 1 or a pull ring 2, the size and shape of which can be flexibly adjusted according to the actual application requirements, such as food packaging or industrial containers.

[0026] The cover body 1 comprises: a cover surface; an expansion ring 18 arranged on the cover surface, which is a whole-circle circular step protruding upward from the cover surface, used to shrink the excess material of the cover surface, strengthen the strength and pressure resistance of the cover surface; a finger platform 16 arranged on the cover surface and located below the opening area of the pull ring 2, which is mainly used to facilitate the opening of the cover surface by the finger acting on the pull ring to complete the opening, and at the same time forms a convex-concave structure with the expansion ring 18 to maintain the tension and strength of the cover surface. The finger platform 16 is designed to be located below the opening area of the pull ring in an arc-shaped long circular structure, which is mainly used to facilitate the opening of the cover surface by the finger acting on the pull ring to complete the opening.

[0027] The expansion ring 18 mainly increases the strength of the cover surface, shrinks the remaining material after the cover surface is formed, guarantees the pressure resistance of the cover surface, and meets the aesthetic effect of the cover surface. The finger platform 16 is below the opening area of the pull ring 2, which is convenient for the user to pull up the pull ring 2 when opening, and forms a convex-concave expansion ring 18 with the cover surface expansion ring 18. The material of the cover surface after stretching and forming is shrunk and flattened, which is more conducive to maintaining the tension and strength of the cover surface.

[0028] The convex-concave shoulder surface 111 is arranged on the edge of the cover surface and located in the contact area with the tank opening, and has a convex-concave structure formed by forward and reverse folding, and has R1 angle (0.3-1.2mm) and R2 angle (1-3mm) and alpha (8°-25°) and delta (5°-15°) two bevel angles in the forward and reverse directions. It is an arc surface for matching the sealing of the tank opening.

[0029] The countersunk rib 112 is arranged on the cover surface, one end of which is connected with the convex-concave shoulder surface 111, and the circular arc at the junction of the convex-concave shoulder surface 111 and the cover surface is the countersunk rib 112 The embedded ring platform 113 is connected with the other end of the countersunk rib 112 at one end and connected with the cover surface at the other end, and has a bevel angle beta (40°-50°) and an R3 angle (0.2-0.8mm), which improves the strength of the tongue piece on the cover surface; the embedded ring platform 113 is a step along the reverse extension of the countersunk rib, which is called embedded ring platform, which can improve the strength.

[0030] The two bevel angles alpha and delta together with the countersunk rib 112 improve the pressure resistance of the cover surface.

[0031] In the present application, the convex-concave shoulder surface is used to cooperate with the tank opening to ensure the use requirements of the tank cover cooperation, the convex-concave structure composed of R1 and R2 in the forward and reverse directions, and the two bevel angles alpha and delta together with the countersunk rib 112 can effectively improve the pressure resistance of the cover surface, while reducing the material area of the cover surface and reducing the material cost of the cover surface. The countersunk rib 112 is an important structure for the pressure resistance of the cover surface, which guarantees that the pressure resistance of the cover surface meets the use requirements of beer or beverage packaging. The embedded ring platform 113 has a bevel angle beta and an R3 angle, which can improve the strength of the tongue piece 12 of the cover surface, thereby guaranteeing the pressure resistance of the tongue piece part of the cover surface.

[0032] The cover body 1 is provided with a folding safety edge 19, which is formed by folding the cover surface after forming a Z-shaped folding shape, and has a space shielding relationship with the score line. When the cover surface is opened, the shielding and space position relationship is used to ensure that the sharp edge of the opening is not easy to cut the user. The opening diameter D2 and the folding diameter D1 satisfy |D1-D2|≤1mm. The folding safety edge 19 is preferably a single safety edge. Through the precise geometric structure and space relationship, a passive and efficient safety protection mechanism is provided, which significantly reduces the risk of cutting the user by the sharp edge during operation, as follows: (1) Intrinsic safety protection: Z-shaped folding structure forms a specific geometric shape and spatial layout. When the cover surface is opened, the folded safety edge 19 will "block" the sharpest part of the cover edge (the sharp edge formed by the scribed line part) in space. The user's touch point or easily accessible part is just behind the protected area, and it is physically difficult to touch the sharp edge itself.

[0033] (2) Precise tolerance control ensures effectiveness: |D1-D2|≤1mm (the difference between the folding diameter and the opening diameter is very small) is the cornerstone of the reliability of this protection function. Such a small tolerance ensures that no matter how the tolerance accumulates, the spatial positional relationship between the safety edge formed by the Z-shaped folding and the actual sharp edge is always stable, and the shielding effect is continuously played. Excessive tolerance may cause shielding failure and exposure of the sharp edge. 1mm control is the minimum feasible size chain accumulation control to achieve this safety purpose.

[0034] (3) Efficient structure design: "The folded safety edge 19 is preferably a single safety edge" indicates that the design pursues simplicity and efficiency. The single safety edge structure is generally simpler than the double edge in folding forming (including mold design, assembly steps), and has lower production cost.

[0035] In summary, the present application ingeniously uses the spatial relationship formed by the bending geometry to realize an important safety function, and ensures its effectiveness through strict size constraints, while optimizing the structure (single safety edge) to ensure the feasibility, economy and reliability of the overall design. It is an efficient, simple and practical anti-cutting solution.

[0036] In the present application, the cover body 1 is also provided with a bird flying scale line 13, which is arranged below the pull ring 2 and close to the rivet 110 on the cover body 1, and is used to break the bird flying scale line 13 when the pull ring 2 and the rivet 110 are pulled first to release the pressure in the tank and prevent the tongue from hurting people as the first scribed line of the cover surface opening of the cover body 1. In the present application, the center arc region scribed line of the bird flying scale line 13 and the rivet 110 on the cover body 1 have a distance L of 0.1-0.9mm. When opening, the pull ring 2 and the rivet 110 break the bird flying scale line 13, at which time the roll circle on the pull ring 2 leaves the cover surface, but the hawk mouth of the pull ring 2 has not yet pressed the main scribed line, and the cover surface is turned over again to complete the initial opening of the cover surface by pressing the cover surface through the hawk mouth of the pull ring 2.

[0037] As Figure 5As shown, the bird flying scale line 13 is similar to the shape of bird wings spread, divided into two main and auxiliary, the main bird flying scale line includes the initial pull open R1 (1-5mm), auxiliary tear open R2 (3-8mm), the center distance L3 (5-20mm) of both ends R2, the auxiliary bird flying scale line is mainly to form a barrier effect, which is conducive to the opening of the main bird flying scale line, and actually does not participate in the opening effect of the cover, and forms an equidistant relationship with the main bird flying scale line, the distance L2 (1-3mm).

[0038] The core advantage of the bird flying scale line 13 is that it provides a staged pressure relief mechanism, which significantly improves the safety of the easy-open can opening process, especially preventing "flying tongue" accidents, as follows: (1) Core advantage: improve opening safety and prevent "flying tongue" injury When the traditional easy-open can is pulled open, the pull ring 2 and the can cover rivet 110 will be torn sharply. If the pressure in the can is too high at this time (such as a gas-containing beverage or a product that deforms the can body due to internal negative pressure), the sudden release of pressure will push the just torn cover piece (commonly known as "pull tongue" or "flying tongue") upward and even out.

[0039] The bird flying scale line 13 is set below the pull ring 2, close to the rivet 110, and is designed as the "first line of defense" in the opening process. When the pull ring 2 is lifted, the pull ring 2 and the lower edge will act on the bird flying scale line 13 first, thereby "tearing" or "breaking" the shorter special scale line. At the moment when the bird flying scale line 13 is broken, before the pull ring 2 is completely turned over and the "beak" of the pull ring 2 (the part at the front end of the pull ring 2 used for pressing down) contacts or breaks the main scale line (the real large opening scale line), a small area (center arc area) surrounded by the bird flying scale line 13 on the can cover is slightly opened, forming a small opening. This small opening instantaneously releases the positive or negative pressure in the can, balancing the pressure difference between the inside and outside of the can. With the smooth release of internal pressure, when the pull ring 2 continues to turn over and its "beak" breaks the main scale line to open the entire cover, the opening of the can cover becomes very smooth and controllable. The risk of the pull ring 2 rebounding violently or the cover piece ("flying tongue") being bounced out at high speed due to the sudden release of pressure is greatly reduced.

[0040] (2) Realize staged opening: the existence of the bird flying scale line 13 clearly divides the opening process of the can cover into two steps: First stage (pressure relief): the pull ring 2 is lifted, the bird flying scale line 13 is broken, and a small area is slightly opened to release pressure (at this time the can cover is not really opened and the contents are not flowing out).

[0041] Second stage (official opening): the pull ring 2 continues to turn over and press down (using the beak), breaking the ring-shaped main scale line 17, and finally turning over the cover.

[0042] This phased design avoids the sudden burst of opening, improves the controllability and fluency of operation, and the overall opening feeling is more stable, smooth and labor-saving.

[0043] (3) Precise control of the pre-splitting point: the key parameter "L" (the distance between the center arc area of the bird flight scale line 13 and the edge of the rivet 110 on the cover body 1) is designed in an extremely small range (0.1-0.9mm). This small distance ensures that the lower circular structure of the pull ring 2 and the edge of the rivet 110 can accurately and reliably "clamp" or "pull" the bird flight scale line 13 at the initial stage of pulling, ensuring that it can be stably and effectively pulled off at this moment. This is the premise of realizing the pressure relief function.

[0044] In the present application, the cover body 1 further comprises: The annular main scale line 17 is the main scale line for opening the cover surface of the cover body 1, which ensures that the cover surface can be fully opened and meets the full opening requirement. The whole is preferably circular.

[0045] The ring nail 15 is arranged on the cover surface of the cover body 1 and directly contacts the pull ring 2, which is used to support the pull ring 2 flat, facilitating the opening of the cover surface.

[0046] The cover supporting nail 14 is arranged on the cover surface of the cover body 1 and located on both sides of the pull ring 2, which is used to support the cover surface flat and limit the rotation of the pull ring 2. It is beneficial to the stability of the stacked transportation of the cover surface, reduces the scratch of the cover surface, and at the same time, the cover supporting nail 14 on both sides of the pull ring 2 forms a limiting action on the pull ring 2, which is beneficial to the anti-rotation of the pull ring 2 and guarantees the opening quality.

[0047] The rivet 110 is arranged on the cover surface of the cover body 1 as the connecting point of the cover surface and the pull ring 2. The rivet 110 is used to rivet the opening pull ring 2 and the cover surface together. When opening the cover surface, through the lever action, the pull ring 2 will pierce the cover surface, and then gradually tear the tongue of the cover surface along the trace of the notch until the cover surface is completely opened.

[0048] The hook edge 11 is the outer diameter part of the cover body 1, and the hook edge 11 part is mainly used to cooperate with the can body to participate in double seaming, meeting the sealing requirement of the can end.

[0049] The tongue is arranged on the cover surface and located inside the main scale line, which is directly related to the main scale line and is used to tear along the trace of the notch during opening, and finally completely open the cover surface.

[0050] The above merely describes preferred specific embodiments of the present application. The protection scope of the present application is not limited to this; any person skilled in the art should be covered in the protection scope of the present application according to the technical solution and the improvement concept of the present application, equivalent replacement or change of the present application within the technical range disclosed by the present application.
