[0002] In the pharmaceutical field, oral solid medications, such as tablets and capsules, typically need to be stored in a dry environment to maintain their efficacy and stability. A humid environment can cause medications to become damp and deteriorate, affecting their efficacy and even producing harmful substances. Poor sealing can lead to external contamination or oxidation, similarly impacting drug quality. Traditional pharmaceutical bottle caps rely on simple sealing structures, which, while blocking external moisture to some extent, cannot effectively absorb moisture that has already entered the bottle. Therefore, medications stored in humid environments for extended periods still face the risk of becoming damp. Utility Model Content

[0003] The purpose of this invention is to provide a moisture-proof combination bottle cap for oral solid medicines. This type of moisture-proof combination bottle cap can absorb moisture that has entered the bottle and improve the sealing performance at the connection between the cap and the bottle body, thereby improving the moisture-proof effect of the cap, preventing the solid medicine from getting damp, and ensuring the quality of the solid medicine during storage.

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] refer to Figure 1-3A moisture-proof combination bottle cap for oral solid medicine includes a bottom cap 1, a retaining ring 2, a moisture-proof component 3, and a sealing ring 4. The bottom cap is the base of the entire bottle cap. The retaining ring 2 is coaxially mounted on the bottom cap 1 and protrudes from the bottom cap 1. The retaining ring 2 can be made of polypropylene (PP) material. The bottom cap 1 and the retaining ring 2 are inserted into the bottle body for easy installation and removal. The moisture-proof component 3 is coaxially mounted inside the retaining ring 2 and protrudes from the retaining ring 2. 3. It can absorb moisture from the bottle cap and bottle body to achieve moisture protection for medicines. The sealing ring 4 is embedded in the fixing ring 2 and is interference-fitted with the inner wall of the bottle body. The sealing ring 4 can be made of thermoplastic elastomer (TPE) material to achieve fixed connection and sealing between the bottle cap and the bottle body. Through the sealing of the sealing ring 4, external moisture can be prevented from entering the bottle body. The moisture-proof component 3 can absorb the moisture in the bottle body, achieving a combination of moisture prevention and absorption, which can improve the moisture-proof performance of the bottle cap for medicines and ensure the quality of medicines during storage.

[0034] In some embodiments, the moisture-proof component 3 includes a receiving ring 31, an insulating and breathable plate 32, and a moisture-proof material. The receiving ring 31 is coaxially disposed within the fixing ring 2, providing a space for the moisture-proof material. The insulating and breathable plate 32 is sealed on the side of the receiving ring 31 away from the bottom cover 1, forming a receiving cavity with the receiving ring 31 and the bottom cover 1. The moisture-proof material is filled in the receiving cavity. The insulating and breathable plate 32 prevents the moisture-proof material from leaking out while allowing air to pass through, enabling the moisture-proof material to fully contact the air inside the bottle and exert its moisture-absorbing effect. The receiving ring 31 can be made of polypropylene (PP) material, and the insulating and breathable plate 32 can be made of polyethylene (PE) material. Silica gel desiccant can be selected as the moisture-proof material. Silica gel desiccant has strong moisture absorption capacity, is non-toxic and odorless, and is safe and harmless to pharmaceuticals.

[0035] In some embodiments, the moisture-proof component 3 further includes a plurality of vent holes 33 disposed on the receiving ring 31, which can increase the contact area between the moisture-proof material and the air inside the bottle, thereby improving the moisture absorption effect and speed of the moisture-proof material.

[0036] In some embodiments, the distance between the plurality of vent holes 33 and the bottom cover 1 is greater than the distance between the fixing ring 2 and the bottom cover 1, so that when air enters the bottle, the moisture in the air can be absorbed in time, and the moisture will not affect the medicine in the bottle if it is not absorbed in time.

[0037] In some embodiments, the outer surface of the fixing ring 2 is an outwardly convex arc surface, which facilitates the insertion and mating of the bottle body and the bottle cap. A fixing groove 21 is provided in the middle of the arc surface, and a sealing ring 4 is provided in the fixing groove 21, which can be interference-fitted with the inner wall of the bottle body to achieve a good sealing effect.

[0038] In some embodiments, the sealing ring 4 includes a sealing part 41 and two guide parts 42. The sealing part 41 is disposed in the fixing groove 21 and is interference-fitted with the inner wall of the bottle body to achieve a seal between the sealing ring 4 and the inner wall of the bottle body. The two guide parts 42 are symmetrically disposed on both sides of the sealing part 41, with one side of the guide part 42 being flush with the sealing part 41 and the other side being flush with the fixing groove 21. The guide parts 42 can guide the sealing ring 4 to smoothly enter the inner wall of the bottle body during the tightening of the bottle cap, reducing installation resistance and enhancing the stability of the sealing ring 4.

[0039] In some embodiments, the surface of the sealing part 41 is provided with a plurality of deformation grooves. The deformation grooves are arranged obliquely, which makes it easier for the sealing part 41 to deform when it is squeezed, thereby better fitting with the inner wall of the bottle and further improving the sealing performance. At the same time, it can increase the contact area between the sealing part 41 and the inner wall of the bottle, increase the friction between the sealing part 41 and the inner wall of the bottle, and improve the stability when the bottle cap is connected to the bottle body.

[0040] In some embodiments, the device further includes a limiting ring 5 and a plurality of spiral connecting pieces 6. The limiting ring 5 is coaxially disposed on the side of the moisture-proof component 3 away from the bottom cover 1. The plurality of spiral connecting pieces 6 are disposed between the limiting ring 5 and the bottom cover 1, and the plurality of spiral connecting pieces 6 are arranged in a ring shape between the fixing ring 2 and the moisture-proof component 3. The limiting ring 5 and the spiral connecting pieces 6 can be made of polypropylene (PP) material, which can provide a certain degree of elasticity and cushioning when the bottle cap is tightened with the bottle body, so as to avoid excessive compression of the moisture-proof component 3 by the medicine inside the bottle body, which would damage the moisture-proof component 3 and cause leakage of the moisture-proof material and contamination of the medicine.

[0041] In some embodiments, the bottom cover 1 includes a bottom plate 11, a bottom ring 12, a limiting groove 13, a rubber ring cover 14, and a rubber sheet (not shown in the figure). The bottom plate 11 can provide stable bottom support for the bottle cap. The bottom ring 12 is disposed on the bottom plate 11, and a fixing ring 2 and a moisture-proof component 3 are coaxially disposed inside the bottom ring 12, which can perform preliminary positioning and protection of the internal structure. The bottom plate 11 and the bottom ring 12 can be made of polypropylene (PP) material, which can meet the requirements of the bottle cap as a pharmaceutical packaging component. A limiting groove 13 is located between the bottom ring 12 and the fixing ring 2 for installing a rubber ring cover 14. The rubber ring cover 14 is embedded in the limiting groove 13 and engages with the bottle mouth, further enhancing the seal between the bottle cap and the bottle body. Multiple rubber sheets are arranged in a ring on the inner wall of the rubber ring cover 14 near the bottom ring 12. When the bottle cap is engaged with the bottle mouth, the rubber sheets are compressed to a certain extent, causing them to deform and reducing the gap between the bottle mouth and the rubber ring cover 14. This prevents moisture from entering the bottle from the engagement point and also reduces the reaction force of the multiple rubber sheets on the bottle mouth, thus reducing the impact on the engagement strength between the bottle body and the bottle cap. The rubber ring cover 14 and the rubber sheets can be made of silicone rubber, which provides a good sealing effect when engaged with the bottle mouth and does not contaminate the medicine.

[0042] In some embodiments, the outer surface of the bottom ring 12 may be provided with friction texture, which can increase the friction between the hand and the bottom cover 1, making it easier to insert and remove the bottle cap from the bottle body.

[0043] In some embodiments, the bottom cover 1 further includes a plurality of vent holes 15, which are arranged in a ring on the bottom plate 11 and between the limiting groove 13 and the bottom ring 12. The vent holes 15 can release excess gas between the bottle cap and the bottle body during the installation process of the bottle cap and the bottle body, so that the bottle cap and the bottle body fit tightly together, and at the same time balance the air pressure inside and outside the bottle to a certain extent, so as to avoid sealing failure due to air pressure difference.

[0044] The specific working principle is as follows:

[0045] In practical use, first install the bottle cap onto the medicine bottle. During installation, the bottle mouth enters the gap between the bottom ring 12 and the fixing ring 2, achieving an initial insertion fit between the bottle cap and the bottle mouth. The bottle body is then inserted towards the bottom plate 11, and the rubber ring cover 14 is tightly embedded in the bottle mouth. The rubber sheet adheres to the inner wall of the bottle mouth, forming the first line of defense for sealing, effectively preventing external moisture and contaminants from entering through the bottle mouth. At the same time, the vent hole 15 on the bottom cap 1 helps to expel excess gas from the bottle during installation, ensuring a tight fit between the bottle cap and the bottle body, balancing the air pressure inside and outside the bottle, and ensuring the stability of the sealing effect.

[0046] Simultaneously, the sealing ring 4 within the fixing groove 21 gradually contacts the inner wall of the bottle during insertion, creating an interference fit. When the sealing part 41 of the sealing ring 4 is compressed by the inner wall of the bottle, the deformation groove on its surface allows it to undergo appropriate elastic deformation, enhancing the sealing performance and ensuring that moisture cannot enter the bottle through the gap between the cap and the bottle body. The moisture-proof material within the receiving ring 31 contacts the moisture inside the bottle through the vent 33, absorbing and adsorbing moisture to prevent the medicine from becoming damp and deteriorating.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
