Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, specifically to an anti-removal tooth structure for a cosmetic bottle cap. Background Technology

[0002] Cosmetics are daily chemical industrial products applied to the human body surface by rubbing, spraying, or other similar methods for cleaning, protecting, beautifying, or modifying. Currently, water-based and cream-based cosmetics are usually stored in bottle-shaped cosmetic containers, which consist of a bottle body and a cap. The bottle body and cap are usually assembled using a threaded connection. However, this method can easily lead to the threads being squeezed due to interference after tightening, causing the threads to come loose. This results in an unstable connection between the bottle body and the cap, affecting the seal. Furthermore, the cap usually has a flip-top for easy opening and closing, but the connection structure between the flip-top and the cap is not strong enough and is prone to breakage after repeated use, affecting the use of the cosmetics. Therefore, there is an urgent need to design a thread-resistant structure for cosmetic bottle caps to improve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an anti-reverse thread structure for cosmetic bottle caps. This aims to solve the problems in existing technologies where, after the bottle body and cap are connected and locked, the threads are easily squeezed by interference, causing the threads to retract. Furthermore, the connection structure between the flip cap and the bottle cap is not strong enough and is prone to breakage after repeated use, affecting the use of cosmetics.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A non-removable tooth structure for a cosmetic bottle cap includes a bottle cap, a flip cap, and a bottle body. The bottle cap and the flip cap are connected by a butterfly-shaped connector. The bottle body is connected to the bottom of the bottle cap. The outer side of the connection opening of the bottle body is provided with threads. A connecting sleeve is fixedly connected inside the bottle cap. A threaded groove is formed on the inner wall of the connecting sleeve. The bottle body and the bottle cap are connected by threads and threaded grooves. The threads include multiple spiral positive threads and auxiliary threads provided on both sides of the positive threads. A sealing structure is provided between the connection opening of the bottle body and the bottle cap.

[0006] Preferably, the butterfly-shaped connector includes a connecting rib plate, the two ends of which are fixedly connected to the bottle cap and the flip cap, respectively. Extending rib plates are fixedly connected to the two ends of the connecting rib plate, and the two ends of the extending rib plates are fixedly connected to the bottle cap and the flip cap, respectively.

[0007] Preferably, a weakening groove is provided at the bottom of the extension stiffener on the side away from the connecting stiffener.

[0008] Preferably, a pair of reinforcing ribs are fixedly connected to the bottom of the extension rib, and the width of the reinforcing ribs gradually decreases along the weakening groove towards the connecting rib.

[0009] Preferably, multiple stabilizing ribs are fixedly connected at the connection between the extension rib and the bottle cap and flip cap.

[0010] Preferably, the sealing structure includes a first sealing ring and a second sealing ring. An installation groove is provided at the end of the connecting port of the bottle body. The first sealing ring is partially embedded in the installation groove. The top cross-section of the first sealing ring is a triangular structure, and the diameter gradually increases from top to bottom. The second sealing ring is fixedly connected to the bottom of the bottle cap and located inside the connecting sleeve. An embedding groove is provided at the bottom of the second sealing ring, and the shape of the embedding groove is adapted to the first sealing ring.

[0011] Preferably, the outer wall of the second sealing ring has a plurality of vent holes communicating with the embedded groove along the circumferential direction.

[0012] Preferably, the end of the connecting sleeve has a mold forming notch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The bottle cap and bottle body of this utility model are connected by a threaded connection of threads and grooves. The threads consist of a main thread and a secondary thread. The secondary thread does not affect the screwing process and requires less force. When the bottle cap is screwed in, the thread groove on the bottle cap and the threads on the bottle body do not interfere with each other. When tightened, the thread groove on the bottle cap and the secondary thread form a locking fit, which is an interference fit. When unscrewing, a lot of force is required, and the secondary thread will interfere and squeeze to prevent the thread from coming off. The advantage of this design is that during transportation, the bottle cap is prevented from falling off or the liquid inside the bottle body is prevented from spilling due to shaking, thus improving the stability and sealing of the connection between the bottle body and the bottle cap.

[0015] 2. This utility model features a butterfly-shaped connector with connecting ribs for connecting the bottle cap and flip cap. The extension ribs enhance the connection area with the bottle cap and flip cap, effectively improving the connection between the flip cap and the bottle cap. The weakening grooves allow the connecting ribs and extension ribs to fold when the flip cap and bottle cap are closed, preventing the butterfly-shaped connector from being torn. The reinforcing ribs improve the structural strength of the extension ribs, and the stabilizing ribs further enhance the structural strength at the connection between the extension ribs and the bottle cap and flip cap, thus extending the service life of the butterfly-shaped connector.

[0016] 3. This utility model, through a sealing structure composed of a first sealing ring and a second sealing ring, allows the top of the first sealing ring to be embedded in the groove of the second sealing ring during the connection and assembly of the bottle body and the bottle cap. The triangular structure design of the first sealing ring and the groove ensures that the smaller diameter end of the first sealing ring enters the larger diameter end of the groove first, which facilitates the fitting and embedding of the first and second sealing rings. Furthermore, the air in the groove is discharged outward through the vent hole. Under the action of the first and second sealing rings, the sealing performance between the bottle body and the bottle cap is greatly improved. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-6This embodiment provides an anti-reverse tooth structure for a cosmetic bottle cap, including a bottle cap 1, a flip cap 2, and a bottle body 4. The bottle cap 1 and the flip cap 2 are connected by a butterfly-shaped connector 3, allowing the flip cap 2 to flip relative to the bottle cap 1 and close. The bottle body 4 is connected to the bottom of the bottle cap 1. A thread 41 is provided on the outer side of the connection opening of the bottle body 4. A connecting sleeve 11 is fixedly connected inside the bottle cap 1. A threaded groove 12 is provided on the inner wall of the connecting sleeve 11. The bottle body 4 and the bottle cap 1 are threadedly connected by the thread 41 and the threaded groove 12. The thread 41 includes multiple spiral-shaped positive teeth 411 and auxiliary teeth 412 located on both sides of the positive teeth 411. The lower auxiliary teeth 412 have a notch at their entry end. A sealing structure is provided between the connection opening of the bottle body 4 and the bottle cap 1. When the bottle cap 1 is assembled, it is connected by the threaded connection between the threaded thread 41 and the threaded groove 12. The threaded thread 41 consists of a main thread 411 and a secondary thread 412. The secondary thread 412 does not affect the screwing process and requires less force. When the bottle cap 1 is screwed in, the threaded groove 12 of the bottle cap 1 and the threaded thread 41 of the bottle body 4 do not interfere. When tightened, the threaded groove 12 on the bottle cap 1 and the secondary thread 412 form a locking fit, which is an interference fit. When unscrewing, a lot of force is required, and the secondary thread 412 will interfere and squeeze to prevent the thread from coming off. The advantage of this design is that during transportation, the bottle cap 1 is prevented from falling off or the liquid in the bottle body 4 is prevented from spilling due to shaking. This improves the stability and sealing of the connection between the bottle body 4 and the bottle cap 1. Furthermore, the sealing effect is further improved by the sealing structure set between the bottle body 4 and the bottle cap 1.

[0026] In this embodiment, as Figure 3 As shown, the butterfly-shaped connector 3 includes a connecting rib plate 31. The two ends of the connecting rib plate 31 are fixedly connected to the bottle cap 1 and the flip cap 2, respectively. The two ends of the connecting rib plate 31 are fixedly connected to the extension rib plate 32, and the two ends of the extension rib plate 32 are fixedly connected to the bottle cap 1 and the flip cap 2, respectively. By setting the extension rib plate 32, the connection area with the bottle cap 1 and the flip cap 2 is strengthened, effectively improving the connection effect between the flip cap 2 and the bottle cap 1.

[0027] In this embodiment, as Figure 3 As shown, a weakening groove 33 is provided at the bottom of the side of the extension rib 32 away from the connecting rib 31. With the weakening groove 33, when the flip cover 2 is closed with the bottle cap 1, the connecting rib 31 and the extension rib 32 are in a folded state. The weakening groove 33 avoids the folded space, making the butterfly-shaped connector 3 less likely to be torn.

[0028] In this embodiment, as Figure 3As shown, a pair of reinforcing ribs 34 are fixedly connected to the bottom of the extension rib 32. The width of the reinforcing ribs 34 gradually decreases along the weakening groove 33 toward the connecting rib 31. Multiple stabilizing ribs 35 are fixedly connected at the connection between the extension rib 32 and the bottle cap 1 and the flip cap 2. The structural strength of the extension rib 32 is improved by the reinforcing ribs 34, and the structural strength of the connection between the extension rib 32 and the bottle cap 1 and the flip cap 2 is improved by the stabilizing ribs 35, thereby increasing the service life of the butterfly connector 3.

[0029] In this embodiment, as Figure 5 and Figure 6 As shown, the sealing structure includes a first sealing ring 5 and a second sealing ring 6. An installation groove 42 is provided at the connecting end of the bottle body 4. The first sealing ring 5 is partially embedded in the installation groove 42. The top cross-section of the first sealing ring 5 is triangular, and its diameter gradually increases from top to bottom. The second sealing ring 6 is fixedly connected to the bottom of the bottle cap 1 and located inside the connecting sleeve 11. An embedding groove 61 is provided annularly at the bottom of the second sealing ring 6. The shape of the embedding groove 61 is adapted to the first sealing ring 5. Multiple grooves corresponding to the embedding groove 61 are provided circumferentially on the outer wall of the second sealing ring 6. When the bottle body 4 and the bottle cap 1 are connected and assembled, the top of the first sealing ring 5 is embedded in the embedding groove 61 of the second sealing ring 6. Through the triangular structure design of the first sealing ring 5 and the embedding groove 61, the smaller diameter end of the first sealing ring 5 enters the larger diameter end of the embedding groove 61 first, which helps the first sealing ring 5 and the second sealing ring 6 to fit together. The air in the embedding groove 61 is discharged outward through the vent hole 62. Under the action of the first sealing ring 5 and the second sealing ring 6, the sealing performance between the bottle body 4 and the bottle cap 1 is greatly improved.

[0030] In this embodiment, the end of the connecting sleeve 11 is provided with a mold forming notch, which serves to prevent the bottle cap 1 from rotating and to position it in the mold, thus facilitating the molding and use of the bottle cap 1.

[0031] Working principle: During use, the bottle body 4 and the bottle cap 1 are connected by threads 41 and 12. Thread 41 consists of a main thread 411 and a secondary thread 412. The secondary thread 412 does not affect the screwing process and requires less force. When the bottle cap 1 is screwed in, the thread groove 12 of the bottle cap 1 and the thread 41 of the bottle body 4 do not interfere. When tightened, the thread groove 12 on the bottle cap 1 and the secondary thread 412 form a locking fit, which is an interference fit. When unscrewing, a large force is required, and the secondary thread 412 will interfere and squeeze to prevent the thread from coming off. This can prevent the bottle cap 1 from falling off during transportation or prevent the liquid in the bottle body 4 from spilling due to shaking, thus improving the stability and sealing of the connection between the bottle body 4 and the bottle cap 1. At this time, the top of the first sealing ring 5 is embedded in the embedding groove 61 of the second sealing ring 6, and the air in the embedding groove 61 is discharged outward through the vent 62. Under the action of the first sealing ring 5 and the second sealing ring 6, the air pressure is greatly reduced. To improve the sealing between the bottle body 4 and the bottle cap 1, the butterfly-shaped connector 3 connects the bottle cap 1 and the flip cap 2 into one unit. The flip cap 2 can be flipped open or closed relative to the bottle cap 1. The connecting rib 31 of the butterfly-shaped connector 3 is used to connect the bottle cap 1 and the flip cap 2. The extension rib 32 strengthens the connection area with the bottle cap 1 and the flip cap 2, effectively improving the connection effect between the flip cap 2 and the bottle cap 1. The weakening groove 33 ensures that the connecting rib 31 and the extension rib 32 are folded when the flip cap 2 is closed with the bottle cap 1. The weakening groove 33 avoids the folded space, making the butterfly-shaped connector 3 less prone to tearing. The reinforcing rib 34 improves the structural strength of the extension rib 32. The stabilizing rib 35 improves the structural strength of the connection between the extension rib 32 and the bottle cap 1 and the flip cap 2, thus increasing the service life of the butterfly-shaped connector 3.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
