Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bottle cap sealing, in particular to a bottle cap sealing structure with half-height threads. Background Art
[0002] Bottle caps are typically used to seal the bottle opening to prevent leakage or contamination of liquids or substances. To ensure that liquids or substances do not leak during transportation or storage, while effectively preventing contaminants from entering the bottle, a bottle cap sealing structure is required. This sealing structure secures the cap to the bottle opening through a spiral convex-concave structure between the cap and the bottle opening, achieving both sealing and securing functions. The cap threads and the bottle opening threads must fully and effectively mate to ensure the cap is securely fastened to the bottle opening, thereby enhancing the cap's sealing properties.
[0003] However, in the existing bottle cap sealing structure, the thread design of the inner wall of the bottle cap is integrated, and the bottle cap thread and the bottle mouth thread cannot effectively cooperate, resulting in the bottle cap being over-rotated or not sealed in place, affecting the sealing effect. In addition, the full height of the bottle cap thread affects the exhaust of the product, which not only causes the ejection and injury when the bottle cap is suddenly opened, but also easily makes it difficult to rinse the bottle mouth, and then causes the liquid at the bottle mouth to mold and deteriorate.
[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0008] Furthermore, in order to firmly connect the sealing bottom cover and the fixed end of the bottle cap through the connecting strip, further enhance the overall stability of the bottle cap and ensure the reliability of the seal, the bottle cap body includes a sealing bottom cover arranged on the top of the fixed end of the bottle cap, and a sealing top cover is arranged on the top of the sealing bottom cover, and the diameter of the sealing bottom cover is larger than that of the sealing top cover, and the bottom end of the sealing bottom cover is evenly provided with a plurality of connecting strips connected to the top end of the fixed end of the bottle cap.
[0009] Furthermore, in order to provide a half-height thread lower than the normal thread height at the disconnected thread of the bottle cap body, it can be ensured that when the product is suddenly opened, the pressure generated can be released through the half-height thread gap, and the flushing liquid can be discharged through the gap when flushing the bottle mouth, thereby avoiding the phenomenon of product deterioration at the bottle mouth, thereby increasing the sealing stress and improving the sealing performance of the bottle cap, and providing additional friction through the friction stripes, which makes it easier to grip when tightening or loosening the bottle cap, thereby enhancing the gripping force and operational convenience of the bottle cap body, a number of friction stripes are evenly provided on the circumferential outer side of the sealing top cover, and a number of threads are provided on the circumferential inner wall of the sealing top cover, and the several threads are staggered in an S shape on the circumferential inner wall of the sealing top cover, and adjacent threads are connected by a number of half-height threads.
[0010] Furthermore, in order to effectively prevent the bottle cap from loosening due to vibration or pressure changes during use, and to provide additional support and fixing force so that the bottle cap can be more firmly stuck on the bottle mouth when tightened to prevent it from falling off, a number of fixing protrusions are evenly arranged on the circumferential inner wall of the fixed end of the bottle cap.
[0011] Furthermore, in order to effectively prevent the bottle cap body from being displaced during use and ensure the stable position of the bottle cap body when it is tightly closed, the limiting assembly includes limiting blocks symmetrically arranged on both sides of the bottom end of the sealed bottom cover, and the limiting block is arranged between two connecting strips, and limiting grooves that cooperate with the limiting blocks are symmetrically opened on both sides of the top end of the fixed end of the bottle cap, and the limiting block and the limiting groove are both trapezoidal structures.

[0014] 2. The utility model provides a half-height thread lower than the normal thread height at the disconnected thread of the bottle cap body, which can ensure that when the product is suddenly opened, the pressure generated can be released through the half-height thread gap, and can also ensure that the flushing liquid can be excreted through the gap when flushing the bottle mouth, avoiding the deterioration of the product at the bottle mouth, thereby increasing the sealing stress and improving the sealing performance of the bottle cap.
[0015] 3.

[0027] In one embodiment, for the above-mentioned bottle cap body 1, the bottle cap body 1 includes a sealing bottom cover 101 arranged on the top of the bottle cap fixed end 2, and a sealing top cover 102 is arranged on the top of the sealing bottom cover 101, and the diameter of the sealing bottom cover 101 is larger than that of the sealing top cover 102, and the bottom end of the sealing bottom cover 101 is evenly provided with a plurality of connecting strips 1011 connected to the top end of the bottle cap fixed end 2, so that the sealing bottom cover 101 and the bottle cap fixed end 2 are firmly connected together through the connecting strips 1011, thereby further enhancing the overall stability of the bottle cap and ensuring the reliability of the seal.
[0028] In one embodiment, for the above-mentioned sealing top cap 102, a plurality of friction stripes 1021 are evenly provided on the outer circumference of the sealing top cap 102, and a plurality of threads 1022 are provided on the inner circumference wall of the sealing top cap 102. The plurality of threads 1022 are staggered in an S shape on the inner circumference wall of the sealing top cap 102, and adjacent threads 1022 are connected by a plurality of half-height threads 1023. Therefore, by providing a half-height thread 1023 lower than the normal thread height at the place where the thread 1022 is disconnected on the bottle cap body 1, it can be ensured that when the product is suddenly opened, the pressure generated can be released through the gap of the half-height thread 1023, and it can also be ensured that the flushing liquid is discharged through the gap when flushing the bottle mouth, thereby avoiding the deterioration of the product at the bottle mouth, thereby increasing the sealing stress and improving the sealing performance of the bottle cap.

[0033] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.
[0034] In actual application, the bottle cap sealing structure with half-height threads provided by the utility model achieves a firm sealing effect through a multi-level sealing design and a limiting component 3; the bottom of the bottle cap body 1 is connected to the bottle cap fixed end 2 through the limiting component 3, and at the same time, the outer side of the sealing top cover 102 is provided with a friction stripe 1021 to enhance the gripping force of the bottle cap body 1, and by providing a half-height thread 1023 lower than the normal thread height at the disconnected thread 1022 of the bottle cap body 1, it can be ensured that when the product is suddenly opened, the pressure generated can be released through the gap of the half-height thread 1023, and it can also be ensured that the flushing liquid is discharged through the gap when the bottle mouth is flushed, thereby improving the sealing performance of the bottle cap.
