Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum cans, and in particular to an aluminum can opening structure with protective function. Background Technology
[0002] Aluminum cans, as a common liquid packaging container, are widely used in the beverage industry, including beer and carbonated drinks, due to their ease of opening and carrying. A traditional aluminum can typically consists of a can body, a lid, and an opening defined by serrated lines. Users pull the tab connected to the opening, causing it to tear along the serrated lines and bend downwards, thus forming the drinking spout.
[0003] However, this traditional opening structure has obvious drawbacks. First, during transportation and sales, the scoring lines and opening area on the can lid are directly exposed, making them susceptible to accidental damage or even breakage due to collisions or friction, resulting in packaging seal failure and leakage of contents; Secondly, the hygiene of the drinking area is difficult to guarantee before opening. Dust, bacteria, or other contaminants can easily accumulate in the grooves of the cut lines. Most importantly, once opened, the opening is permanently damaged and cannot be resealed. This means that if the drinker does not finish the beverage in the can at once, the remaining beverage will be directly exposed to the air. This not only causes carbon dioxide to dissipate rapidly (affecting the taste), but also makes it easier for dust, insects, or foreign objects to fall into the can, which seriously affects the hygiene and safety of the beverage and the drinking experience. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a protective can opening structure to solve the technical problems in the prior art.
[0005] To achieve the above objectives, this utility model provides a protective can opening structure, including a can body and a can lid fixedly attached to the can body, and further comprising: A rivet, which is fixed to the lid of the can; A protective cap, which is rotatably connected to the rivet and can rotate relative to the lid of the can; The can lid has a scribing line, which defines an opening. The opening is connected to the can lid at the scribing line, thereby sealing the opening. The front end of the protective cover overlaps the opening plate.
[0006] Preferably, the etched line is a non-closed contour that defines the opening plate, and the opening plate closes the opening when it is not open.
[0007] Preferably, the protective cover is made of aluminum.
[0008] Preferably, the protective cover has a through hole, and the rivet passes through the through hole, so that the protective cover can rotate around the rivet.
[0009] Preferably, the inner wall of the perforation is provided with a plurality of elastic elements at equal intervals along the circumference, and the outer wall of the rivet is provided with locking elements at equal intervals along the circumference that cooperate with the elastic elements, and the locking elements overlap the surfaces of two adjacent elastic elements to restrict the rotation of the protective cover.
[0010] Preferably, the elastic element is a semi-circular spring sheet, and the locking element is semi-circular and cooperates with the elastic element.
[0011] Preferably, the coverage area of the rear end of the protective cover is larger than the area enclosed by the etched line. When the rear end of the protective cover is rotated to the position of the etched line, it can block the area above the etched line, thereby protecting the opening piece.
[0012] Preferably, the top surface of the protective cover away from its connection with the rivet has a snap groove for inserting a finger to pry open the protective cover.
[0013] The beneficial effects of this utility model are as follows: The protective can opening structure of this utility model is designed with components such as a protective cap, elastic element, and locking element. When the can is not opened, the front end of the protective cap overlaps the opening piece, forming a physical cover on the opening piece. This significantly reduces the risk of accidental breakage of the scoring line due to transportation vibration, collision, or friction, ensuring the sealing integrity of the packaging. In addition, the protective cap can effectively shield the scoring line and drinking area, reducing the contamination of the drinking area by dust, bacteria, and other pollutants. With its rotating design and the cooperation of elastic and locking components, the protective cap allows users to rotate it to cover the drinking area during non-drinking periods after initial opening, creating a temporary seal. This greatly reduces the possibility of beverages being contaminated by insects, dust, or human-caused foreign objects, ensuring drinking hygiene. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0018] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0019] The first aspect of this utility model proposes a protective can opening structure, such as... Figure 1-5 As shown, the device includes a can body and a can lid 1 that is sealed and fixed to the can body, and also includes: Rivet 2 is fixed to the lid 1 of the can. The protective cover 3 is rotatably connected to the rivet 2 and can rotate relative to the can lid 1. The scoring line 101 defines an opening piece 4 on the can lid 1. The opening piece 4 is connected to the can lid 1 at the scoring line 101, thereby closing the opening. It should be noted that the scoring line 101 is stamped on the can lid 1 by a mold to form a non-closed contour, such as a U-shape or a C-shape. The front end of the protective cover 3 overlaps the opening piece 4.
[0020] Before drinking, the rear end of the protective cap 3 is rotated above the opening piece 4. When not in use, the protective cap 3 covers the area of the opening piece 4 through the overlapping relationship to prevent it from being opened accidentally. At the same time, it protects the area of the etched line 101 to reduce the accumulation of dust, bacteria or foreign matter in the drinking area.
[0021] In this embodiment: the etched line 101 is a non-closed contour, which defines the opening piece 4, and the opening piece 4 closes the opening when it is not open. It should be noted that the non-closed contour refers to the etched line 101 that is not completely drawn around the edge. It is like a circle, U-shape, or other shape with a gap, and this opening piece 4 is connected to the main body of the can lid 1 through that part of the "disconnection", forming a natural hinge, so it will not completely fall off when opened.
[0022] In this embodiment, the protective cover 3 is made of aluminum. Aluminum is lightweight, corrosion-resistant, and easy to process, making it suitable for food packaging.
[0023] In this embodiment: the protective cover 3 is provided with a through hole, and the rivet 2 is inserted through the through hole, so that the protective cover 3 can rotate around the rivet 2.
[0024] In this embodiment: the inner wall of the perforation is provided with a plurality of elastic elements 5 at equal intervals along the circumference, and the outer wall of the rivet 2 is provided with locking elements 6 at equal intervals along the circumference to cooperate with the elastic elements 5, and the locking elements 6 overlap the surfaces of two adjacent elastic elements 5 to restrict the rotation of the protective cover 3. This cooperation between the elastic elements 5 and the locking elements 6 forms a ratchet-type locking mechanism, which allows the protective cover 3 to be locked when rotated to a specific position to prevent accidental rotation. For example, when the rear end of the protective cover 3 covers the opening piece 4, the locking elements 6 engage with the elastic elements 5 to fix the position of the protective cover 3; when the user applies sufficient force, the elastic elements 5 deform, and the protective cover 3 can be rotated to the open position.
[0025] In this embodiment: the elastic element 5 is a semi-circular spring sheet, and the locking element 6 is semi-circular and cooperates with the elastic element 5. It should be noted that this shape matching improves the stability and durability of the locking.
[0026] In this embodiment, the rear end of the protective cover 3 covers an area larger than the area enclosed by the etched line 101. When the rear end of the protective cover 3 is rotated to the position of the etched line 101, it can block the area above the etched line 101, thereby protecting the opening piece 4. After opening, the user can rotate the protective cover 3 to cover the opening piece 4 and the area of the etched line 101, preventing dust or foreign objects from entering. During non-drinking periods, it effectively prevents dust, insects, and human-caused foreign objects from falling in.
[0027] In this embodiment, a groove 7 is provided on the top surface of the protective cover 3 away from its connection with the rivet 2. The groove 7 is used for inserting a finger to pry open the protective cover 3. The groove 7 is designed to make it easy for the user to pry up the protective cover 3 with their fingers, so that the front end of the protective cover 3 can be pressed down on the opening piece 4 with the rivet 2 as the axis to open it, making it easy and effortless to use the beverage.
[0028] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
[0029] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
