Description

Technical Field

[0001] This utility model relates to the field of rubber stopper technology, specifically a moisture-proof and sealing medical rubber stopper. Background Technology

[0002] Rubber stoppers are sealing devices used in chemical experiments. They are made of rubber and are also called rubber stoppers. Chemical instruments without ground joints can generally be sealed with rubber stoppers. Rubber stoppers come in different sizes, with size 1 being the smallest; the larger the number, the larger the volume. A rubber stopper can be perforated with a hole and inserted into a glass tube to form a connection device, allowing gas to be released from a sealed container.

[0003] However, in the existing technology, most rubber stoppers have poor moisture-proof sealing performance, and the rubber stoppers are relatively soft and difficult to pull out, which is quite laborious.

[0004] To address the aforementioned issues, Chinese utility model patent CN217321479U discloses a moisture-proof and sealing medical rubber stopper, comprising a bottle body with a stopper cap fixed to the bottle body. A circular ring is fixedly installed at the bottom of the stopper cap, and a stopper head is fixedly installed at the bottom of the stopper cap. The stopper head is located inside the bottle body, and its bottom is trapezoidal. During use, the bottle body is sealed by two sealing rings. A permeable annular mesh and a moisture-absorbing ring absorb any infiltrated moisture, keeping the bottle opening dry and preventing moisture buildup. When the stopper cap and stopper head need to be removed, the pull block is engaged, and the force-bearing block and pull plate enhance the support force during pulling, making it easier to remove the stopper cap and stopper head and preventing slippage.

[0005] However, the aforementioned rubber stoppers do not provide a direct view of the sealing effect and moisture barrier performance, and since they rely solely on a single moisture-absorbing ring for moisture protection, the effect is not ideal. Utility Model Content

[0006] The purpose of this invention is to provide a moisture-proof and airtight medical rubber stopper that effectively prevents moisture from entering the bottle through the bottle opening while visually demonstrating the moisture barrier effect through a multi-layered moisture barrier structure.

[0007] This utility model is implemented as follows:

[0008] A moisture-proof and sealing medical rubber stopper includes a stopper cap, a stopper ring fixedly connected to the circumferential side of the stopper cap to match the outer circumferential side of the bottle mouth, a stopper head fixedly connected to the bottom of the stopper cap to match the inner circumferential side of the bottle mouth, a water-sensing component embedded in the inner side of the stopper ring, a moisture-absorbing membrane disposed between the water-sensing component and the bottle mouth, the moisture-absorbing membrane being fixedly connected to the stopper ring, a transparent observation window disposed on the outer circumferential side of the stopper ring, the transparent observation window being positioned corresponding to the water-sensing component, and a moisture-absorbing ring disposed between the stopper ring and the stopper head, the moisture-absorbing ring being fixedly connected to the stopper cap.

[0009] Furthermore, the water-sensing component is a water-sensing anti-counterfeiting paper.

[0010] Furthermore, the stopper has a cavity for holding the desiccant, and a breathable diaphragm is provided at one end of the opening of the cavity, the breathable diaphragm being fixedly connected to the stopper.

[0011] Furthermore, a barbed ring is fixedly connected to the side of the stopper that is in contact with the bottle opening, and the cross-section of the barbed ring decreases from the stopper side to the bottle opening side.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In practical applications, the stopper is inserted into the bottle mouth, the stopper ring covers the outside of the bottle mouth, and the top of the bottle mouth is placed between the stopper ring and the stopper, abutting against the moisture-absorbing ring. The moisture-absorbing membrane and water-sensing component provide the first layer of absorption and barrier against moisture. At the same time, the reaction of the water-sensing component can be observed through a transparent viewing window, visually demonstrating the moisture barrier situation. While absorbing moisture, the moisture-absorbing membrane protects the bottle mouth from contact with the water-sensing component, preventing bottle mouth contamination. The moisture-absorbing ring between the stopper ring and the stopper provides the second layer of absorption and barrier against moisture, absorbing any moisture that has passed through the first layer of absorption and barrier again, effectively preventing moisture from passing through the bottle mouth and entering the bottle. This utility model, through its multi-layered moisture barrier structure, effectively prevents moisture from passing through the bottle mouth and entering the bottle, while also providing a visual demonstration of the moisture barrier situation.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Please see Figure 1 A moisture-proof and sealing medical rubber stopper includes a stopper cap 1, a stopper ring 2 that matches the outer ring of a bottle mouth 100 fixedly connected to the circumferential side of the stopper cap 1, a stopper head 3 that matches the inner ring of the bottle mouth 100 fixedly connected to the bottom of the stopper cap 1, a water-sensing component 4 embedded in the inner side of the stopper ring 2, a moisture-absorbing membrane 5 disposed between the water-sensing component 4 and the bottle mouth 100, the moisture-absorbing membrane 5 being fixedly connected to the stopper ring 2, a transparent observation window 6 disposed on the outer ring of the stopper ring 2, the transparent observation window 6 being positioned corresponding to the water-sensing component 4, and a moisture-absorbing ring 7 disposed between the stopper ring 2 and the stopper head 3, the moisture-absorbing ring 7 being fixedly connected to the stopper cap 1.

[0019] In practical applications, the stopper 3 is inserted into the bottle mouth 100, the stopper ring 2 covers the outside of the bottle mouth 100, and the top of the bottle mouth 100 is placed between the stopper ring 2 and the stopper 3, abutting against the moisture-absorbing ring 7. The moisture-absorbing membrane 5 and the water-sensing component 4 provide the first layer of absorption and barrier against moisture. At the same time, the reaction of the water-sensing component 4 can be observed through the transparent observation window 6, visually demonstrating the moisture barrier situation. While absorbing moisture, the moisture-absorbing membrane 5 protects the bottle mouth 100 from contact with the water-sensing component 4, preventing contamination of the bottle mouth 100. The moisture-absorbing ring 7 between the stopper ring 2 and the stopper 3 provides the second layer of absorption and barrier against moisture, absorbing any moisture that has passed through the first layer of absorption and barrier again, effectively preventing moisture from passing through the bottle mouth 100 and entering the bottle. This utility model, through its multi-layered moisture barrier structure, effectively prevents moisture from passing through the bottle mouth 100 and entering the bottle, while also providing a visual demonstration of the moisture barrier situation.

[0020] Please see Figure 1The water-sensing component 4 is a water-sensing anti-counterfeiting paper. When water in the moisture comes into contact with the water-sensing anti-counterfeiting paper, the color of the water-sensing anti-counterfeiting paper can be observed through the transparent observation window 6, for example, changing from white to red, which can intuitively show the moisture barrier effect. The moisture-absorbing membrane 5 and the moisture-absorbing ring 7 are both made of cotton, and the thickness of the moisture-absorbing membrane 5 is less than the thickness of the moisture-absorbing ring 7.

[0021] Please see Figure 1 The plug 3 has a receiving cavity 9 for containing desiccant, and a breathable diaphragm is provided at one end of the opening of the receiving cavity 9. The breathable diaphragm is fixedly connected to the plug 3.

[0022] The breathable membrane is made of thin cotton and is used to absorb some of the moisture in the air inside the bottle. The desiccant in the receiving cavity 9 absorbs the moisture that passes through the breathable membrane, thus preventing the material inside the bottle from being affected by the moisture in the air.

[0023] Please see Figure 1 The stopper 3 is fixedly connected to the side of the bottle mouth 100 with a barbed ring 8. The cross-section of the barbed ring 8 decreases from the stopper 3 side to the bottle mouth 100 side.

[0024] When the stopper 3 is inserted into the bottle opening 100, the barbed ring 8 forms a moisture barrier with the inside of the bottle opening 100, effectively improving the sealing effect.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
