[0001] The present invention relates to the field of can lids, particularly to full-open lids.

Background Art

[0002] Conventional can lids can be opened in a winding manner by providing a cut line.

[0003] For example, Patent Document with Publication Number CN113928681A discloses a double-protection edge type full-open lid. The protection edge region includes a first protection edge region, a first cut line, and a second protection edge region. The first cut line is provided along the periphery of the central panel, restricting the central panel. The first cut line separates the first protection edge region and the second protection edge region, and the first protection edge region is located on the outer periphery of the central panel.

[0004] However, in the above technology and conventional technologies, the cut line is arranged along the outer periphery of the outer edge of the central panel, with no connection points or only one connection point, resulting in poor stability.

[0005] Therefore, in order to solve the above technical problems, a full-open lid is proposed.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In order to solve the above technical problems, the object of the present invention is to provide a full-open lid with a simple structure and excellent stability.

Means for Solving the Problems

[0007] The technical solution used by this invention to solve the problem is as follows: The fully opening lid is a body provided with an annular cut line, the annular cut line divides the body into an outer ring portion and a central panel, the annular cut line is provided with cutting portions that connect to the outer ring portion and the central panel, respectively, the number of cutting portions is at least two, and the central panel is provided with a pull ring.

[0008] As a further improvement to the above technical means, a first edge winding portion is provided on the inner circumferential edge of the outer ring portion, and the first edge winding portion protrudes from the inner circumferential edge of the outer ring portion.

[0009] As a further improvement to the above technical means, a second edge winding portion is provided on the edge of the central panel, and the second edge winding portion protrudes from the edge of the central panel.

[0010] As a further improvement to the above technical means, the pull ring is provided with a through hole, and a connecting member that is fixedly connected to the central panel is fixedly mounted inside the through hole.

[0011] As a further improvement to the above technical means, rivets are provided in the central panel, and the connecting member is riveted to the central panel via the rivets.

[0012] As a further improvement to the above technical means, a point of application is provided at one end of the pull ring.

[0013] A beneficial effect of this invention is that the cut line has two cutting sections, meaning there is no cut line in the two cutting sections, thereby ensuring the connection stability between the outer ring and the central panel.

[0014] The present invention will be further interpreted and described below with reference to a brief description of the drawings and embodiments for carrying out the invention. [Brief explanation of the drawing]

[0015] [Figure 1] This is a schematic diagram of a preferred embodiment of the present invention. [Figure 2] This is an enlarged schematic diagram of the structure of part A shown in Figure 1. [Figure 3] Figure 1 is an exploded perspective view of the object shown. [Figure 4] Figure 3 is an enlarged schematic diagram of the structure of part B shown. [Figure 5] This is a cross-sectional view of the present invention. [Modes for carrying out the invention]

[0016] The following describes specific embodiments of the present invention in detail. Preferred embodiments of the present invention are shown in the accompanying drawings, which complement the textual descriptions in the specification with diagrams and allow for an intuitive and visual understanding of each technical feature and the overall technical solution of the present invention. These drawings are not intended to limit the scope of protection of the present invention.

[0017] In describing this invention, it is important to understand that the descriptions of directions, such as up, down, front, back, left, right, etc., are based on the directions or positional relationships shown in the drawings and merely serve to facilitate and simplify the explanation of this invention. They do not indicate or imply that the shown device or element has a specific direction or must be constructed and operated in a specific direction, and therefore cannot be understood as limiting this invention.

[0018] In the description of this invention, the term "several" means one or more, and the term "multiple" means two or more. Terms such as "greater than," "less than," and "greater than" do not include a reference number, while terms such as "greater than or equal to," "less than or equal to," and "within" include a reference number. The descriptions in the first and second sections are merely for distinguishing technical features and should not be interpreted as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship of the indicated technical features.

[0019] In the description of the present invention, unless otherwise clearly limited, terms such as installation, attachment, connection, etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in the present invention by combining the specific content of the technical solution.

[0020] Referring to FIGS. 1 to 5, the fully open lid includes a main body provided with an annular cut line 4. The annular cut line 4 divides the main body into an outer ring portion 1 and a central panel 2. The annular cut line 4 is provided with a cutting portion 22 respectively connected to the outer ring portion 1 and the central panel 2, and a pull ring 3 is provided on the central panel 2. The cut line 4 is not provided on the cutting portion 22, and the outer ring portion 1 and the central panel 2 are connected by the cutting portion 22. The number of the cutting portions 22 is at least two, thereby ensuring the structural stability and preventing the central panel 2 from separating from the outer ring portion 1 due to impact.

[0021] As a preferred embodiment, a first edge winding portion 11 is provided on the inner peripheral edge of the outer ring portion 1, and the first edge winding portion 11 protrudes from the inner peripheral edge of the outer ring portion 1. In the state where the central panel 2 is open, the sharp edge of the outer ring portion 1 is covered by the first edge winding portion 11, thereby preventing the user from being injured or scratched.

[0022] As a preferred embodiment, a second edge winding portion 23 is provided on the edge of the central panel 2, and the second edge winding portion 23 protrudes from the edge of the central panel 2. In the state where the central panel 2 is open, the sharp edge of the central panel 2 is covered by the second edge winding portion 23, thereby preventing the user from being injured or scratched.

[0023] As a preferred embodiment, a through hole 31 is provided in the pull ring 3, and a connecting member 32 fixedly connected to the central panel 2 is fixedly attached in the through hole 31.

[0024] As a preferred embodiment, a rivet 21 is provided on the central panel 2, and the connecting member 32 is riveted to the central panel 2 via the rivet 21.

[0025] In a preferred embodiment, a point of application 33 is provided at one end of the pull ring 3.

[0026] The foregoing are merely preferred embodiments of the present invention and do not limit the scope of the patent of the present invention. Any equivalent structural modifications made using the contents of the specification and accompanying drawings of the present invention, or any modifications applied directly or indirectly to other related technical fields, shall be included within the scope of the patent protection of the present invention.
