Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal packaging container technology, and in particular to a high-strength easy-open lid that can increase the number of packages. Background Technology
[0002] To increase the strength and pressure resistance of easy-open lids while maintaining the same material thickness and strength, reinforcing ribs are typically added to the lid surface. For example... Figures 1-3 As shown, existing reinforcing rib structures are usually stepped, with each step gradually concave downwards from the outer ring to the inner ring. When stacked, the concave step plane contacts the pull ring, increasing the stacking distance. Consequently, for the same packaging size, the number of packages is reduced, increasing packaging and transportation costs. Utility Model Content
[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a high-strength easy-open lid that can increase the number of packages. This solves the technical problem that when such structures are stacked, the concave step plane contacts the upper pull ring, increasing the stacking distance, reducing the number of packages per unit volume, and increasing logistics costs.
[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A high-strength easy-open cap that can increase packaging capacity includes a cap and a pull tab. The cap has at least three concentrically distributed wavy continuous reinforcing ribs, each rib having a recessed depth at the same horizontal plane. Adjacent reinforcing ribs form an upwardly extending support plane. The wavy reinforcing ribs include a first reinforcing rib, a second reinforcing rib, and a third reinforcing rib, arranged sequentially from the center of the cap to the outer periphery. The support plane has an angle of 10°-30° with the horizontal plane. The edge of the cap has a finger groove with a depth less than the recessed depth of the wavy reinforcing ribs. The spacing between the crests of the wavy reinforcing ribs is less than the width of the pull tab.
[0005] (III) Beneficial Effects Revolutionary improvement in space utilization The wave-shaped reinforcing ribs, through the wave crest point contact mechanism, significantly reduce the ineffective gaps during stacking, thereby fundamentally optimizing the stacking density within the same packaging volume and directly improving warehousing and transportation loading efficiency.
[0006] Achieving synergy between strength and lightweight While fully inheriting the compressive strength of traditional stepped reinforcing ribs, the innovative structure eliminates redundant material accumulation, achieving "space compression with zero strength loss" and breaking through the long-standing strength-volume contradiction in the industry.
[0007] Structural optimization of costs across the entire supply chain The qualitative change in stacking density brings about a triple reduction in packaging material usage, storage space occupation, and transportation frequency, resulting in a systemic cost reduction from the production end to the logistics end.
[0008] Compatibility and innovative design The wavy topology forms an adaptive contact mode with the existing pull ring system, enabling technological upgrades without the need to modify the supporting packaging equipment, thus significantly reducing the threshold for industrialization. Attached Figure Description
[0009] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

Figure 3 This refers to the overlap distance of the old structure; Figure 4 This is a cross-sectional view and an enlarged view of the structure of this utility model; Figure 5 The overlapping distance of the structure of this utility model.
[0011] Legend: 1. Cover; 2. Pull ring; 3. Continuous wavy reinforcing rib; 31. First reinforcing rib; 32. Second reinforcing rib; 33. Third reinforcing rib; 4. Supporting plane; 5. Finger groove provided on the edge. Detailed Implementation
[0012] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the overall concept of the technical solution in this application embodiment is as follows: To address the problems existing in the prior art, this utility model provides a high-strength easy-open lid that can increase the number of packages, including a lid surface 1 and a pull ring 2. The lid surface 1 is provided with at least three concentrically distributed wavy continuous reinforcing ribs 3, the depth of each reinforcing rib is at the same horizontal plane, and an upwardly extending support plane 4 is formed between adjacent reinforcing ribs.
[0013] The wavy reinforcing rib 3 includes a first reinforcing rib 31, a second reinforcing rib 32 and a third reinforcing rib 33, which are arranged sequentially from the center of the cover to the outer periphery. The angle between the supporting plane 4 and the horizontal plane is 10°-30°. The edge of the cover 1 is provided with a finger groove 5, the depth of which is less than the recess depth of the wavy reinforcing rib 3. The spacing between the crests of the wavy reinforcing rib 3 is less than the width of the pull ring 2.
[0014] Working principle: like Figure 1 As shown, the easy-open lid consists of a lid and a pull ring. The lid is designed with a first reinforcing rib, a second reinforcing rib, a third reinforcing rib, and a finger groove. 2) such as Figure 4 As shown, the reinforcing ribs are wavy in shape, the depth of the concave ribs is on the same horizontal plane, and the reinforcing ribs form an upward-sloping plane. 3) This wavy reinforcing rib structure can provide the same surface reinforcement as the stepped reinforcing rib structure, improving the product's pressure resistance; at the same time, compared to the progressively concave stepped reinforcing rib, it has less impact on the stacking distance. For example... Figure 3 and Figure 5 The overlap distances for the two structures are shown. The overlap distance for the stepped shape is 2.73–3.2 mm, with an average of 2.965 mm, while the overlap distance for the wavy shape is 2.3 mm, which is a reduction of 22.4%. This means that with the packaging size remaining the same, the packaging quantity can be increased by 22.4%, greatly reducing packaging and transportation costs.
[0015] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
