High-quality iron box

Abstract

This utility model discloses a high-quality tin box, including a box body and a lid. Both the outer ends of the box body and the lid have annular grooves. The bottom of each annular groove has multiple vertical grooves, and a compression spring is inserted and fixed within each groove. An annular impact ring is located at the upper end of the compression spring. This utility model has the following advantages and effects: The impact rings at the top and bottom of the tin box help reduce deformation or damage to the box itself under impact, extending the packaging's lifespan. It also avoids or reduces damage to the internal items due to impact and vibration. In particular, it enhances the impact resistance in scenarios such as transportation, handling, or accidental drops, ensuring items arrive at their destination more safely and reliably.

Description

Technical Field

[0001] This utility model relates to the field of tin box technology, and in particular to a high-quality tin box. Background Technology

[0002] Metal packaging boxes are widely used in high-end food, gifts, tea, cosmetics, and collectibles due to their durability, good sealing, high-end appearance, and recyclability. However, accidental drops of metal boxes during transportation, handling, or use are difficult to completely avoid, and the resulting damage has always been a pain point in the industry.

[0003] Existing tin box structures primarily rely on the rigidity of their metal shells for protection. When a tin box is dropped, especially landing on a sharp edge or its top / bottom surface, the immense impact force acts directly on the metal walls. Because metal materials (such as tinplate) have limited plastic deformation capacity under strong localized impacts, they are highly susceptible to damage such as dents, scratches, paint chipping, and even cracks at the point of impact. This damage not only severely affects the box's aesthetics and overall quality, significantly reducing its product value and lowering consumer experience and satisfaction, but also, in some cases (such as deformation of the sealing edge), may impair its sealing function, leading to moisture absorption, spoilage, or leakage of the contents. Utility Model Content

[0004] The purpose of this invention is to provide a high-quality iron box that can effectively improve its resistance to drop impacts and prevent damage to its appearance.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-quality iron box, including a box body, a cover body provided on the box body, an annular groove provided on the outer side of the end of the box body and the end of the cover body, a plurality of vertical grooves provided at the bottom of the annular grooves, a compression spring passing through and fixed in the vertical grooves, and an annular impact ring provided at the upper end of the compression spring.

[0006] The further configuration includes: a groove on the outer wall of the box, a sliding rod in the groove, one end of the sliding rod facing the bottom of the box being connected to an impact ring at the bottom; and an annular blocking ring at the other end, which abuts against the impact ring on the cover.

[0007] The box body is further configured such that it has a wooden outer cover, and the sliding groove is provided on the wooden outer cover.

[0008] Further configuration: the outer edge of the impact ring is provided with multiple annular bends.

[0009] In summary, this utility model has the following beneficial effects: The impact rings at the top and bottom of the tin box help mitigate deformation or damage that may occur during impacts, extending the packaging's lifespan. It also prevents or reduces damage to the internal items caused by impact and vibration. In particular, it enhances the impact resistance during transportation, handling, or accidental drops, ensuring items arrive at their destination more safely and reliably.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] A high-quality tin box includes a box body 1, which is made of traditional tinplate that is rolled and fixed. The overall structure of the box body 1 is cylindrical, and a lid 2 is provided on the box body 1. The lid 2 is connected to the box body 1 by threads. The dotted lines shown in the figure represent the structure of the box body 1 and the lid 2 themselves.

[0014] Both the outer ends of the box body 1 and the lid 2 have annular grooves 3. Multiple vertical grooves 4 are provided at the bottom of each annular groove 3, forming a ring around the circular cross-section of the box body 1 or lid 2. A compression spring 5 is inserted and fixed within each vertical groove 4, and an annular impact ring 6 is located at the upper end of the compression spring 5. The outer radius of the impact ring 6 is larger than the diameter of the lid 2 or box body 1 itself, thus providing a buffer space. Under the action of the compression spring 5, the height of the impact ring 6 is also higher than the height of the lid 2. When the box body 1 is placed down, the impact ring 6 is flush with the bottom of the box body 1 under the influence of gravity; however, when it is picked up, the impact ring 6 will spring downwards a certain distance under the action of the compression spring 5. The impact ring 6 cushions the impact of the box upon drop, thus reducing the problem of deformation and deterioration of the appearance of traditional metal boxes.

[0015] The two ends of the compression spring 5 are fixed and connected to the bottom of the annular groove 3 and the impact ring 6, respectively. Preferably, a vertical rod can also be set in the middle of the compression spring 5 to ensure the state of the compression spring 5 so that it will not be overloaded and tilted.

[0016] A wooden cover 10 is fitted on the outer wall of the box body 1. The wooden cover 10 has multiple grooves 7. A sliding rod 8 is installed in the grooves 7. One end of the sliding rod 8 facing the bottom of the box body 1 is directly connected to the impact ring 6 at the bottom. The other end, which faces the cover 2, is provided with an annular blocking ring 9. When the box body 2 is in the position, the blocking ring 9 abuts against the lower end of the impact ring 6 on the cover 2.

[0017] In terms of appearance, the outer wall of the sliding rod 8 is flush with the outer wall of the box body 1, and the same complete image is printed on it. For image alignment, the bottom of the impact ring 6 should be flush with the bottom of the box body 1 when the box is placed flat. In this structure, the sliding rod 8 is used to resist the concave deformation caused by impacts between the outer wall of the box body 1 and external protrusions.

[0018] The outer edge of the impact ring 6 is provided with multiple annular bends 11. The annular folds can resist deformation, thereby reducing deformation problems and minimizing aesthetic loss when this position is impacted by the outside.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
