Description

Technical Field

[0001] This invention relates to the field of pharmaceutical containers, and more particularly to a loose-sealing design structure for medicine bottles. Background Technology

[0002] Pharmaceutical preparations are stored in medicine bottles. In pharmacies, after the bottle containing the pharmaceutical preparation is opened, a sealing device is needed to seal the bottle. During storage, it is necessary to prevent the evaporation of the medicine inside the bottle and preserve the remaining pharmaceutical preparation. Therefore, the sealing device used for medicine bottles is an important medical device.

[0003] Currently, sealing gaskets are commonly used for sealing. The sealing gaskets on the market are generally aluminum foil gaskets. Once the gasket is opened, the sealing function of the aluminum foil will be destroyed, and the remaining paper gasket does not have a sealing effect. For medicines that are repeatedly opened, they can only be sealed by the bottle cap. However, there is a gap between the bottle cap and the bottle, which is easy to loosen and the sealing effect is not good. Opened medicines cannot be stored for a long time. Summary of the Invention

[0004] The purpose of this invention is to provide a loosening-proof sealing design structure for medicine bottles in order to solve the problem of poor sealing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a loosening-proof sealing design structure for a medicine bottle, comprising:

[0006] Bottle body, the bottle body having a storage cavity;

[0007] The first sealing component includes several sealing plates, a toothed disc, a toothed ring, and a connecting rod component. The toothed disc is rotatably connected to the bottle body and meshes with the toothed ring. The toothed ring is provided with a plurality of connecting rod components along its circumference. The other end of the connecting rod component is connected to the sealing plate, and the sealing plate is movably connected to the bottle mouth of the bottle body through the connecting rod component.

[0008] A bottle cap, which is detachably attached to the bottle body;

[0009] A second sealing component is disposed on the bottle cap, and after the bottle cap is installed, the second sealing component abuts against the sealing plate.

[0010] As a further description of the above technical solution:

[0011] The connecting rod assembly includes a fixed column, a rotating column, a connecting plate, and a connecting rod. The fixed column is fixedly connected to the bottle body, the rotating column is rotatably connected to the fixed column, one end of the rotating column is connected to the sealing plate, and the other end of the rotating column is connected to the connecting plate. One end of the connecting rod is movably connected to the connecting plate, and the other end of the connecting rod is fixedly connected to the gear ring.

[0012] As a further description of the above technical solution:

[0013] The connecting plate is provided with a movable elongated hole, and one end of the connecting rod passes through the movable elongated hole.

[0014] As a further description of the above technical solution:

[0015] The sealing plate is a fan-shaped plate, and the circle formed by several horizontally opened sealing plates is adapted to the size of the bottle opening.

[0016] As a further description of the above technical solution:

[0017] A support column is provided inside the bottle, and the end of the sealing plate away from the rotating column is rotatably connected to the support column via a rotating shaft.

[0018] As a further description of the above technical solution:

[0019] The bottle body is provided with a raised ring, and the raised ring is provided with a movable space. The toothed ring is movably connected within the movable space.

[0020] As a further description of the above technical solution:

[0021] The second sealing component includes a stud, a movable column, and a sealing unit. The stud has an upper pressure plate at its bottom, the movable column is screwed to the bottom of the stud, the movable column has a lower pressure plate at its bottom, and the sealing unit is disposed between the upper pressure plate and the lower pressure plate.

[0022] As a further description of the above technical solution:

[0023] The sealing unit is an annular airbag, which is sleeved on the movable column.

[0024] As a further description of the above technical solution:

[0025] Both the upper pressure platform and the lower pressure platform have trapezoidal cross-sections.

[0026] As a further description of the above technical solution:

[0027] The bottle cap is threaded onto the bottle body.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In this invention, the sealing plate, gear plate, gear ring, and connecting rod components enable the gear plate to rotate when it rotates, which in turn drives the gear ring to rotate. The connecting rod rotates with the gear ring, and at this time, the connecting rod is inserted into one end of the movable elongated hole, which drives the connecting plate to rotate. This causes the rotating column to rotate within the fixed column, thereby causing the sealing plate to rotate and thus opening and closing the bottle mouth. By using a sealing plate, the bottle is not easily deformed, and the bottle cap is not easily loosened. Compared with rubber gaskets, the sealing effect is better.

[0030] 2. In this invention, the stud, movable column, and sealing unit ensure that during installation, the bottle cap rotates, the lower pressure plate abuts against the sealing plate, and the movable column rotates with the stud. The top of the movable column moves upward into the stud, causing the upper and lower pressure plates to press the sealing unit from both above and below. This facilitates the sealing unit's contact with the inner wall of the bottle to form a seal. Simultaneously, the upper and lower pressure plates and the sealing unit also form a seal through pressure contact. Thus, the first and second sealing components form a double-layer sealing structure with excellent sealing performance. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figure 1-7 This invention provides a technical solution: an anti-loosening sealing design structure for a medicine bottle, comprising:

[0043] Bottle body 1, wherein the bottle body 1 has a storage cavity;

[0044] The first sealing component includes several sealing plates 2, a toothed disc 3, a toothed ring 4, and a connecting rod component 5. The toothed disc 3 is rotatably connected to the bottle body 1, and the toothed disc 3 meshes with the toothed ring 4. The toothed ring 4 is provided with a plurality of connecting rod components 5 along its circumference. The other end of the connecting rod component 5 is connected to the sealing plate 2, and the sealing plate 2 is movably connected to the bottle mouth of the bottle body 1 through the connecting rod component 5.

[0045] Bottle cap 6, which is detachably connected to the bottle body 1;

[0046] The second sealing component is disposed on the bottle cap 6. After the bottle cap 6 is installed, the second sealing component abuts against the sealing plate 2.

[0047] The connecting rod component 5 includes a fixed column 51, a rotating column 52, a connecting plate 53, and a connecting rod 54. The fixed column 51 is fixedly connected to the bottle body 1, and the rotating column 52 is rotatably connected to the fixed column 51. One end of the rotating column 52 is connected to the sealing plate 2, and the other end is connected to the connecting plate 53. One end of the connecting rod 54 is movably connected to the connecting plate 53, and the other end is fixedly connected to the gear ring 4. The fixed column is fixedly connected to the bottle body and is a hollow column with openings at both ends. The rotating column is damped and rotatably connected to the fixed column, so the rotating column will not rotate on its own, resulting in good stability. In use, the gear ring rotates, causing the connecting rod to move the connecting plate, which in turn drives the rotating column to rotate, thereby causing the sealing plate on the rotating column to rotate, realizing the opening and closing of the bottle mouth. The operation is convenient, the sealing plate is not easily deformed, and the sealing effect is good.

[0048] The connecting plate 53 is provided with a movable elongated hole 7, and one end of the connecting rod 54 passes through the movable elongated hole 7. This can restrict the movement space of the connecting rod.

[0049] The sealing plate 2 is a fan-shaped plate, and the circle formed by several horizontally opened sealing plates 2 is adapted to the size of the bottle opening. This can improve the sealing effect.

[0050] like Figure 4 In one embodiment, a support column 8 is provided inside the bottle body 1, and the end of the sealing plate 2 away from the rotating column 52 is rotatably connected to the support column 8 via a rotating shaft. This makes the rotation of the sealing plate more stable.

[0051] The bottle body 1 is provided with a raised ring 9, and a movable space is provided inside the raised ring. The toothed ring 4 is movably connected within the movable space. This can hide the first sealing component, making the bottle body more aesthetically pleasing. The raised ring has a through hole for the toothed disc to move, which facilitates the control of the toothed disc's rotation.

[0052] The second sealing component includes a stud 10, a movable post 11, and a sealing unit 12. An upper pressure plate 13 is provided at the bottom of the stud, and the movable post 11 is screwed to the bottom of the stud 10. A lower pressure plate 14 is provided at the bottom of the movable post 11, and the sealing unit 12 is disposed between the upper pressure plate 13 and the lower pressure plate 14. When the bottle cap rotates, the movable post and the stud also rotate, and the top of the movable post enters the stud from the top, causing the upper and lower pressure plates to press the sealing unit from both above and below. This facilitates contact between the sealing unit and the inner wall of the bottle to form a seal, while simultaneously creating pressure contact between the upper and lower pressure plates and the sealing unit.

[0053] The sealing unit 12 is an annular airbag, which is sleeved on the movable column 11. The annular airbag deforms under pressure and recovers its shape when no pressure is applied, resulting in a long service life.

[0054] Both the upper pressure plate 13 and the lower pressure plate 14 have trapezoidal cross-sections, which improves the sealing effect.

[0055] The bottle cap 6 is threaded onto the bottle body 1.

[0056] Working principle: The system utilizes a sealing plate, gear disc, gear ring, and connecting rod assembly. When the gear disc rotates, it drives the gear ring to rotate, and the connecting rod rotates with the gear ring. At this time, the connecting rod, inserted into one end of the movable elongated hole, drives the connecting plate to rotate, causing the rotating column to rotate within the fixed column, which in turn rotates the sealing plate, thus opening and closing the bottle mouth. The use of a sealing plate ensures it is not easily deformed, and the bottle cap is less likely to loosen, providing a better seal compared to rubber gaskets. When dispensing medicine, the gear disc rotates in the opposite direction, creating a gap between the sealing plates for easy dispensing. The gear disc and gear ring work together to control the rotation angle of the sealing plate, facilitating dispensing. The system also incorporates a stud, movable column, and connecting rod assembly. The sealing unit allows the bottle cap to rotate during installation. The lower pressure plate presses against the sealing plate, and as the cap rotates, the movable column and stud also rotate. The top of the movable column moves upwards into the stud, causing the upper and lower pressure plates to press the sealing unit from both above and below. This facilitates contact between the sealing unit and the inner wall of the bottle, forming a seal. Simultaneously, the pressure between the upper and lower pressure plates and the sealing unit also creates a seal. Thus, the first and second sealing components form a double-layer sealing structure with excellent sealing performance. When the bottle cap is rotated in the opposite direction to open, the distance between the movable column and stud increases, and the sealing unit returns to its original position.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
