Technical Field

[0001] This utility model relates to the field of medicine bottles, specifically a medicine glass bottle with good sealing effect. Background Technology

[0002] In the pharmaceutical packaging industry, pharmaceutical glass bottles are widely used due to their advantages such as good chemical stability, high transparency, and ease of sterilization and cleaning. However, the airtightness of pharmaceutical glass bottles is crucial for maintaining the quality and shelf life of medicines. Traditional pharmaceutical glass bottles are usually sealed with simple threaded caps, but this sealing method often has problems such as incomplete sealing and easy loosening. Especially during transportation and storage, the cap may loosen due to vibration, leading to contamination or spoilage of the medicine.

[0003] To address these issues, some improved sealing structures for pharmaceutical glass bottles have emerged on the market, such as adding sealing elements like rubber gaskets or O-rings. However, while these improvements enhance sealing performance to some extent, they still have shortcomings. For example, rubber gaskets or O-rings are prone to aging, deformation, or detachment, thus affecting the sealing effect; furthermore, the replacement and installation of these sealing elements are relatively complex, which is detrimental to the production and quality control of pharmaceutical packaging.

[0004] Therefore, developing a sealing structure for pharmaceutical glass bottles that offers good sealing performance, simple structure, and ease of installation and maintenance has become an urgent problem to be solved in the current pharmaceutical packaging field. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical glass bottle with good sealing performance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical glass bottle with good sealing effect, comprising a glass bottle body, a plastic bottle cap fitted on the top of the glass bottle body, a rubber retaining ring inserted into the bottom end of the plastic bottle cap, the rubber retaining ring being fitted onto an inlet ring, and the inlet ring being fixed to the surface of a retaining ring.

[0007] The retaining ring is fixed to the top of the glass bottle.

[0008] Preferably, the top of the glass bottle is provided with an external thread, and the inner ring surface of the plastic bottle cap is provided with an internal thread, and the internal thread and the external thread are connected in a mating manner.

[0009] Preferably, a rubber stopper is fixed to the bottom surface of the top plate of the plastic bottle cap. The rubber stopper has a frustum-shaped structure, the top diameter of the rubber stopper is larger than the bottom diameter of the rubber stopper, and the bottom end of the rubber stopper is inserted into the mouth of the glass bottle, the top diameter of the rubber stopper is larger than the mouth diameter of the glass bottle.

[0010] Preferably, the slot is an annular groove with a circular opening, and the rubber retainer is an annular plate with a circular cross-section, wherein the cross-sectional diameter of the rubber retainer is larger than the groove opening width.

[0011] Preferably, the top surface of the plastic bottle cap has a notch, and a transparent sheet is fixed between the two parallel sidewalls of the notch.

[0012] Preferably, a rubber strip is fixed to the surface of the notch, the rubber strip is located between the notch and the transparent sheet, and there are two rubber strips, which are respectively distributed at both ends of the bottom surface of the notch.

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

[0014] This invention proposes a pharmaceutical glass bottle with excellent sealing performance. The first sealing structure is formed by the tight fit between a rubber stopper and the bottle mouth. The trapezoidal plate structure of the rubber stopper allows it to more effectively fill the gap between the bottle mouth and the cap, thus improving the sealing effect. The threaded connection between the plastic cap and the glass bottle body constitutes the second sealing structure. This double sealing structure greatly enhances the sealing performance of the pharmaceutical glass bottle, effectively preventing contamination and spoilage of the medicine during transportation and storage. A rubber retaining ring is inserted into the bottom of the plastic cap, which is fitted onto the guide ring and inserted into the groove. The elastic compression of the rubber retaining ring not only enhances the connection stability between the cap and the glass bottle body but also acts as a buffer and shock absorber, further improving the sealing performance and durability of the pharmaceutical glass bottle.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a pharmaceutical glass bottle with good sealing effect, comprising a glass bottle body 1, a plastic bottle cap 2 fitted on the top of the glass bottle body 1, an external thread on the top of the glass bottle body 1, and an internal thread on the inner ring surface of the plastic bottle cap 2, the internal and external threads being connected in a mating manner. A rubber stopper plate 3 is fixed to the bottom surface of the top plate of the plastic bottle cap 2, the rubber stopper plate 3 having a frustum-shaped plate structure, the top diameter of the rubber stopper plate 3 being larger than the bottom diameter of the rubber stopper plate 3, and the bottom end of the rubber stopper plate 3 being inserted into the bottle mouth of the glass bottle body 1, the top diameter of the rubber stopper plate 3 being larger than the bottle mouth diameter of the glass bottle body 1. After the plastic bottle cap 2 is fitted and screwed onto the top of the glass bottle body 1, the rubber stopper plate 3 is inserted into the bottle mouth of the glass bottle body 1, achieving a sealing of the bottle mouth of the glass bottle body 1, and the screw connection between the plastic bottle cap 2 and the glass bottle body 1 constitutes a second sealing structure.

[0024] A rubber retaining ring 7 is inserted into the bottom of the plastic bottle cap 2. The rubber retaining ring 7 is fitted onto the guide ring 6, which is fixed to the surface of the retaining ring 5. The retaining ring 5 is fitted onto the top of the glass bottle body 1. The retaining groove 4 is an annular groove with a rounded opening. The rubber retaining ring 7 is an annular plate with a rounded cross-section. The diameter of the rubber retaining ring 7 is larger than the width of the groove 4. When the plastic bottle cap 2 is screwed onto the mouth of the glass bottle body 1, the guide ring 6 and the rubber retaining ring 7 are inserted into the retaining groove 4. The rubber retaining ring 7 is pressed inside the retaining groove 4, which not only acts as an elastic washer after the plastic bottle cap 2 and the glass bottle body 1 are screwed together, but also provides traction for the plastic bottle cap 2, preventing it from falling off the glass bottle body 1.

The information on the paper strip can be viewed through the transparent sheet 9.

[0026] The following is the procedure for using a well-sealed pharmaceutical glass bottle:

[0027] Confirm that the rubber stopper 3 is correctly fixed to the bottom surface of the top plate of the plastic bottle cap 2, ensuring that the bottom diameter of the rubber stopper 3 is smaller than the bottle mouth diameter of the glass bottle 1, but the top diameter is larger than the bottle mouth diameter, in order to form an effective seal. Align the plastic bottle cap 2 with the top of the glass bottle 1, ensuring that the internal threads are aligned with the external threads. Slowly rotate the plastic bottle cap 2 until it is fully tightened, at which point the rubber stopper 3 should be tightly inserted into the bottle mouth of the glass bottle 1. Confirm that the rubber retaining ring 7 is fitted onto the guide ring 6, the guide ring 6 is firmly fixed onto the retaining ring 5, and the retaining ring 5 is fitted onto the top of the glass bottle 1. When the plastic bottle cap 2 is fully tightened, the guide ring 6 and the rubber retaining ring 7 should smoothly insert into the retaining groove 4. The rubber retaining ring 7 will be squeezed tightly against the inside of the retaining groove 4, forming a second seal and preventing the bottle cap from loosening. Prepare a strip of paper with medicinal information written on it. Open the notch 8 on the top surface of the plastic bottle cap 2 and carefully insert the strip of paper into the gap between the transparent sheet 9 and the notch 8. Ensure the paper strip is flat, wrinkle-free, and completely covers the transparent sheet 9. Use the rubber strips 10 on both sides of the notch 8 to increase friction between the paper strip and the notch 8, preventing the paper strip from falling off. Check and ensure the paper strip is secure; the information on the paper strip should be clearly visible through the transparent sheet 9. Store the sealed medicine glass bottle in a dry, cool place, avoiding direct sunlight and high temperatures. When using, rotate the plastic cap 2 counterclockwise until fully loosened, taking care not to damage the rubber stopper 3 and rubber retaining ring 7.
