Description

Technical Field

[0001] The invention relates to the field of medicine containers, and in particular to an anti-loosening sealing design structure for a medicine bottle. Background Art

[0002] Drug preparations are stored in medicine bottles. In a pharmacy, when a medicine bottle containing a drug preparation is opened, a sealing device is required to seal the medicine bottle. During storage, the volatilization of the drug in the bottle must be avoided and the remaining drug preparation must be preserved. Therefore, the sealing device for the medicine bottle is an important medical device.

[0003] At present, sealing gaskets are usually used for sealing. The sealing gaskets on the market are generally gaskets sealed with aluminum foil. Once the gasket is opened, the sealing function of the aluminum foil will be destroyed, and the remaining paper gasket has no sealing properties. For medicines that are opened repeatedly, the bottle cap can only be used for sealing. However, there is a gap between the bottle cap and the bottle, which is easy to loosen and has a poor sealing effect. The opened medicines cannot be stored for a long time. Summary of the invention

[0042] See also Figure 1-7 The present invention provides a technical solution: a medicine bottle anti-loosening sealing design structure, which includes:

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

[0044] A first sealing component, the first sealing component comprises a plurality of sealing plates 2, a toothed disc 3, a gear ring 4 and a connecting rod component 5, the toothed disc 3 is rotatably connected to the bottle body 1, the toothed disc 3 is meshed with the gear ring 4, the gear 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] A bottle cap 6, wherein the bottle cap 6 is detachably connected to the bottle body 1;

[0046] The second sealing component is arranged 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, 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, the other end of the rotating column 52 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 of the connecting rod 54 is fixedly connected to the gear ring 4. The fixed column is fixedly connected to the bottle body, and the fixed column is a hollow column with openings at both ends. The rotating column is connected to the fixed column with damping rotation, so that the rotating column will not rotate by itself, and has good stability. When in use, the gear ring rotates, so that the connecting rod drives the connecting plate to move, and the connecting plate drives the rotating column to rotate, thereby driving the sealing plate on the rotating column to rotate, so as to realize the opening and closing of the bottle mouth, which is convenient to operate, the sealing plate is not easy to deform, and the sealing effect is good.

[0048] The connecting plate 53 is provided with a movable long hole 7, and one end of the connecting rod 54 is inserted into the movable long hole 7. In this way, the movable space of the connecting rod can be limited.

[0049] The sealing plate 2 is a fan-shaped plate, and a circle formed by a plurality of sealing plates 2 spread out horizontally is adapted to the size of the bottle mouth, so as to improve the sealing effect.

[0050] like Figure 4 In one embodiment, a support column 8 is provided in the bottle body 1, and one 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 can make the rotation of the sealing plate more stable.

[0051] The bottle body 1 is provided with a convex ring 9, in which a movable space is provided, and the gear ring 4 is movably connected in the movable space. This can hide the first sealing component and make the bottle body more beautiful. The convex ring is provided with a through hole for the gear disc to move, which is convenient for controlling the rotation of the gear disc.

[0052] The second sealing component includes a stud 10, a movable column 11 and a sealing unit 12. An upper pressing platform 13 is provided at the bottom of the stud. The movable column 11 is screwed to the bottom of the stud 10. A lower pressing platform 14 is provided at the bottom of the movable column 11. The sealing unit 12 is provided between the upper pressing platform 13 and the lower pressing platform 14. When the bottle cap rotates, the movable column and the stud also rotate, and the top of the movable column enters the stud upward, so that the upper pressing platform and the lower pressing platform squeeze the sealing unit from the upper and lower directions, so that the sealing unit contacts the inner wall of the bottle body to form a seal, and at the same time, the upper pressing platform and the lower pressing platform are squeezed and contacted with the sealing unit.

[0053] The sealing unit 12 is an annular airbag, which is sleeved on the movable column 11. The annular airbag is deformed by force and recovers when no force is applied, so the service life is long.

[0054] The cross sections of the upper pressing platform 13 and the lower pressing platform 14 are both trapezoidal, which can improve the sealing effect.

[0055] The bottle cap 6 is threadedly connected to the bottle body 1 .

[0056] Working principle: through the sealing plate, toothed disc, gear ring and connecting rod components, when the toothed disc rotates, the toothed disc drives the gear ring to rotate, and the connecting rod rotates with the gear ring. At this time, the connecting rod is inserted into the end of the movable long hole to drive the connecting plate to rotate, so that the rotating column rotates in the fixed column, and then the sealing plate rotates to realize the opening and closing of the bottle mouth. By adopting the sealing plate for sealing, it is not easy to deform, and the bottle cap is not easy to loosen. Compared with the rubber pad, the sealing effect is better; when pouring the medicine, the toothed disc rotates in the opposite direction, so that the gap between the sealing plates flows out to pour the medicine, which is easy to operate; the toothed disc and the gear ring cooperate to control the rotation angle of the sealing plate, which is convenient for pouring the medicine; through the studs, movable columns and sealing The sealing unit enables the bottle cap to rotate when being installed, and the lower pressing platform presses against the sealing plate. When the bottle cap rotates, the movable column and the stud also rotate, and the top of the movable column enters the stud upward, so that the upper pressing platform and the lower pressing platform squeeze the sealing unit from upper and lower directions, and the sealing unit is convenient to contact with the inner wall of the bottle body to form a seal. At the same time, the upper pressing platform, the lower pressing platform and the sealing unit are squeezed and contacted, so that the upper pressing platform, the lower pressing platform and the sealing unit are also sealed; in this way, the first sealing component and the second sealing component form a double-layer sealing structure with good sealing effect; when the bottle cap is reversely rotated to open, the distance between the movable column and the stud becomes larger, and the sealing unit also returns to its original state.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
