[0002] At present, there are frequent complaints from users about the brittleness of capsules and other preparations in China. Many pharmaceutical companies are very concerned about this. The reason is that after the hollow capsule is filled with drug powder, the hygroscopicity of the drug powder causes the water in the capsule shell to migrate. The water content of the capsule shell is very low. On the other hand, the water content of the preparation is specified in the standard. If it exceeds the standard, it will be treated as an inferior drug. In order to ensure that the water content of the preparation does not exceed the standard, pharmaceutical companies put bagged desiccant in the bottle after the capsule is filled with drug powder, which aggravates the brittleness of the capsule. However, there are reasons for the brittleness of the capsule. On the one hand, the water content of the capsule shell is very low. On the other hand, the capsule shell is easily brittle when it is affected by external forces when it loses water. Therefore, anti-brittle plastic bottle caps are needed. Utility Model Content

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative efforts shall fall within the scope of protection of the present utility model.

[0021] At present, complaints from users due to the friability of capsules and other preparations are very frequent in China. Many pharmaceutical companies are very troubled by this. The reason is that after the hollow capsule is filled with powder, due to the hygroscopicity of the powder, the moisture in the capsule shell migrates. The moisture content of the capsule shell is very low. On the other hand, the moisture content of the preparation is regulated by standards, and preparations exceeding the standards are treated as substandard drugs. In order to ensure that the moisture content of the preparation does not exceed the standard, pharmaceutical companies need to place desiccant bags in the bottles after the capsules are filled with powder, which increases the friability of the capsules. However, there are reasons for the friability of the capsules. On the one hand, the moisture content of the capsule shell is very low. On the other hand, the capsule shell is prone to friability when affected by external forces under the condition of water loss. Please refer to Figures 1-4 , this embodiment provides an anti-friable plastic bottle cap, including the bottle cap 1.

[0022] Refer to Figures 2-3As shown, at present, complaints from users due to the friability of capsules and other preparations are very frequent in China. Many pharmaceutical companies are very troubled by this. The reason is that after the hollow capsule is filled with powder, due to the hygroscopicity of the powder, the moisture in the capsule shell migrates. The moisture in the capsule shell is very low. On the other hand, the moisture of the preparation is regulated by standards, and if it exceeds the standard, it will be treated as a substandard drug. In order to ensure that the moisture of the preparation does not exceed the standard, pharmaceutical companies have to place desiccants in bags when bottling the capsules filled with powder, which increases the friability of the capsules. However, the friability of the capsules is due to certain reasons. On the one hand, the moisture in the capsule shell is very low. On the other hand, when the capsule loses water and is affected by external forces, the capsule shell is prone to friability. In order to prevent the content (capsule) from being friable, the following two settings are made. The first is that there is a desiccant-loading component 2 at the bottom of the bottle cap 1. The desiccant-loading component 2 includes a top shell 22 fixed to the bottom end of the transfer cylinder 33. The outer wall of the top shell 22 is threadedly connected to a bottom cover 21. A loading space is formed between the top shell 22 and the bottom cover 21. There are several ventilation holes 23 on the top shell 22 for the desiccant to carry out moisture absorption operations. The desiccant is placed in the bottom cover 21 to form a closed loading space. This design can ensure that the desiccant does not directly contact the content, thus avoiding the impact on it. The ventilation holes 23 on the top shell 22 allow air to circulate, enabling the desiccant to effectively absorb moisture without directly affecting the capsule. This design can protect the integrity of the content while ensuring the desiccant plays its role. By isolating the desiccant from the capsule, it can effectively prevent the capsule from becoming fragile due to moisture absorption or other chemical reactions, thereby reducing the risk of friability. This design can ensure the stability of the content during long-term storage. The rotational connection between the bottom cover 21 and the top shell 22 makes the device easy to install and replace the desiccant, and at the same time simplifies the operation process.

[0023] Reference Figures 2-3As shown in the figure, secondly, an anti-fragility mechanism 3 is provided at the top of the bottle cap 1 to reasonably adjust the downward movement of the dosing component 2 to press against the content to prevent it from shaking according to the stacking height of the content in the plastic bottle. The anti-fragility mechanism 3 includes a lead screw 32 rotatably arranged on the inner wall of the bottle cap 1. The top of the lead screw 32 is fixedly connected with a rotating plate 31. A groove is formed at the top of the bottle cap 1. The rotating plate 31 is arranged inside the groove, and the top of the rotating plate 31 is flush with the top of the bottle cap 1. A moving cylinder 33 is threadedly connected to the outer wall of the lead screw 32. The dosing component 2 is arranged at the bottom of the moving cylinder 33. A positioning component for enabling the moving cylinder 33 to move directionally along the outer wall of the lead screw 32 is arranged on the outer wall of the moving cylinder 33. The positioning component includes two slide bars 35 symmetrically arranged on both sides of the moving cylinder 33. Two mounting plates 34 are arranged on the outer wall of the moving cylinder 33 from top to bottom. One of the mounting plates 34 is fixed to the outer wall of the moving cylinder 33, and both slide bars 35 are slidably sleeved inside it. The other mounting plate 34 is slidably sleeved on the outer wall of the moving cylinder 33. The two ends of the two slide bars 35 are respectively fixedly connected to it and the bottle cap 1. By rotating the rotating plate 31 to drive the lead screw 32 to rotate, the moving cylinder 33 moves downward, and the position of the dosing component 2 can be automatically adjusted according to the height of the content in the plastic bottle. This adjustment can adapt to the content with a continuously decreasing stacking height during use, ensuring the flexibility of the device. The minimum device space formed between the bottom of the dosing component 2 and the space inside the plastic bottle can effectively limit the movement range of the content. This tight space configuration reduces the shaking of the content in the bottle and reduces the risk of brittle breakage caused by collision. By reducing the movement of the content, the stability of the content is increased, and the damage caused by violent shaking can be effectively avoided, improving the reliability of the overall product. This design not only improves the safety of the content but also helps to extend its shelf life.

[0024] Reference Figure 3 As shown in the figure, a softening pad 4 for enhancing the softness of contact with the content is fixedly bonded to the bottom of the bottom cover 21. The material of the softening pad 4 includes but is not limited to polyurethane foam and polyethylene foaming material. The design of the softening pad 4 can further enhance the protection of the content, thereby preventing brittle breakage and improving the reliability of the product. The softening pad 4 is made of soft materials such as polyurethane foam or polyethylene foaming material, which can effectively buffer the collision of the content in the plastic bottle, reduce the hardness of direct contact, and thus reduce the impact force on the content. At the same time, the soft characteristics of the softening pad 4 enable it to disperse the pressure applied to the content, further reducing the influence of external forces on the content and preventing brittle breakage caused by excessive pressure. Overall, the use of the softening pad 4 improves the safety of the content, ensures the integrity of the content during storage and transportation, and extends its service life.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
