Description

Technical Field

[0001] The present invention relates to the field of drug preservation, and specifically to a sealing device for improving the sealing effect of bacteriostatic liquid. Background Art

[0002] Bacteriostatic liquid, as the name implies, is a medical liquid used to inhibit the survival and reproduction of bacteria and fungi. Its main function is to inhibit bacterial and fungal infections and has a good therapeutic effect on various infectious skin diseases.

[0003] To ensure the effectiveness of bacteriostatic liquid and extend its shelf life, reasonable sealed preservation is required. Traditional solution bottles use screw - on caps to seal the bottle mouths. However, this method only blocks the contact between the liquid medicine in the bottle body and the outside air, but the contact between the liquid medicine and the air inside the bottle body is not cut off. Moreover, as the liquid medicine is used, the volume ratio of the liquid medicine to the air in the bottle gradually decreases, which further accelerates the deterioration and invalidation of the liquid medicine in the later stage.

[0004] Therefore, a new sealing device for improving the sealing effect of bacteriostatic liquid is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a sealing device for improving the sealing effect of bacteriostatic liquid.

[0011] As a further solution of the present invention: The one-way cylinder includes an air chamber, a partition member and a valve plate. The air chamber is a hollow body embedded in the buckle cover. One side of the air chamber is provided with channels respectively communicating with the bottom and the circumferential surface of the buckle cover to realize communication with the storage bottle body and the outside. A T-shaped partition member is arranged in the air chamber to divide the space in the air chamber into three independent spaces, including two parallel communication chambers respectively communicating with the storage bottle body and the outside, and a piston chamber located on one side of the communication chambers and unidirectionally communicating with both communication chambers. There is a valve plate moving along the direction of the piston chamber in the piston chamber, and the valve plate is driven by a driving knob to perform reciprocating motion along the direction of the piston chamber.

[0012] As a further solution of the present invention: The partition member includes a partition plate and a valve flap. The partition plate is T-shaped and fixed inside the air chamber to partition the air chamber.

The inner side of the knob wheel is provided with circumferentially distributed trigger keys, and the trigger keys intermittently contact the valve plate as the knob wheel rotates to drive the movement of the valve plate.

[0014] As a further solution of the present invention: The one-way cylinder or the trigger key is asymmetrically arranged.

[0015] As a further solution of the present invention: An elastic member is arranged at the connection between the valve plate and the air chamber, and the elastic member acts on the valve plate to keep the valve plate always tending to move towards the partition member.

Beneficial effects

[0017] 1. An exhaust mechanism communicating with the bottom of the buckle cover is arranged on the buckle cover of the present invention. The exhaust mechanism is composed of a one-way cylinder that exhausts unidirectionally between the storage bottle body and the outside and a driving knob rotatably connected to the top of the buckle cover that drives the one-way cylinder to operate.

[0030] The present embodiment provides a sealing device for improving the sealing effect of antibacterial liquid, comprising a collar 1 fixedly sleeved at the mouth of a storage bottle body 5, a buckle cover 3 connected to the collar 1 through a buckle belt 2 to seal the middle opening of the collar 1, and an exhaust mechanism 4 connected to the bottom of the buckle cover 3 is provided on the buckle cover 3, and the exhaust mechanism 4 is composed of a one-way cylinder 41 for one-way exhaust between the storage bottle body 5 and the outside, and a driving knob 42 rotatably connected to the top of the buckle cover 3 for driving the one-way cylinder 41 to operate;

[0031] By turning the driving knob 42 on the top, the one-way cylinder 41 in the buckle cover 3 can be driven to perform one-way exhaust, so as to extract the gas in the storage bottle body 5, increase the vacuum degree in the storage bottle body 5, slow down the deterioration of the antibacterial liquid in the storage bottle body 5 caused by contact with the air, and extend the shelf life of the antibacterial liquid after opening.

[0032] The buckle cover 3 includes a cover body 31 and an inhibitor chamber 32. The cover body 31 is connected to the collar 1 through the buckle belt 2. A protruding inhibitor chamber 32 is provided at the bottom center of the cover body 31. The inhibitor chamber 32 is a cylinder corresponding to the central through hole of the collar 1. The inside is filled with a reaction inhibitor 33. The bottom of the inhibitor chamber 32 is closed by a waterproof and breathable cover 34 made of a waterproof and breathable material.

[0033] By filling the reaction inhibitor 33, through the reaction between the reaction inhibitor 33 and the air components, some components in the air that can react with the antibacterial liquid can be removed, achieving the effect of extending the shelf life of the antibacterial agent.

[0034] Specifically, an annular sealing rubber ring 35 is provided at the connection between the cover body 31 and the inhibitor chamber 32 to improve the sealing performance of the closed part. At the same time, by utilizing the flexible characteristics of the sealing rubber ring 35 and the reduction in air pressure brought about by the air extraction mechanism 4 for the storage bottle body 5, the sealing rubber ring 35 is further fitted to improve the sealing performance.

[0035] Specifically, circumferentially distributed groove chucks are provided on the circumferential surface of the inhibitor chamber 32, and corresponding protruding chucks are provided on the inner side of the collar 1 to improve the stability of the buckling connection between the collar 1 and the buckle cover 3.

[0036] Among them, the one-way cylinder 41 includes an air chamber 411, a partition member 412 and a valve plate 413. The air chamber 411 is a hollow body embedded in the buckle cover 3. One side of the air chamber 411 is provided with channels respectively communicating with the bottom and the circumferential surface of the buckle cover 3 to realize the connection with the storage bottle body 5 and the outside. A T-shaped partition member 412 is arranged in the air chamber 411 to divide the space in the air chamber 411 into three independent spaces, including two parallel communication chambers respectively communicating with the storage bottle body 5 and the outside, and a piston chamber located on one side of the communication chambers and unidirectionally communicating with both communication chambers. There is a valve plate 413 moving along the direction of the piston chamber in the piston chamber, and the valve plate 413 is driven by a driving knob 42 to perform reciprocating motion along the direction of the piston chamber;

[0037] By setting the parallel communication chambers and the piston chamber on one side, the unidirectional discharge of the gas in the storage bottle body 5 is driven by the movement of the valve plate 413, reducing the air content in the storage bottle body 5, increasing the vacuum degree, and extending the shelf life of the antibacterial agent.

[0038] Specifically, the partition member 412 includes a partition plate 4121 and a valve flap 4122. The partition plate 4121 is T-shaped and fixed inside the air chamber 411 to divide the air chamber 411. Two air windows communicating the communication chambers and the piston chamber are opened on the partition plate 4121, and a rubber valve flap 4122 with one-way opening is arranged at the air windows. The opening direction of the valve flap 4122 is from the storage bottle body 5 to the communication chamber and from the communication chamber to the outside.

[0039] Specifically, the driving knob 42 includes a knob wheel 421 and a trigger key 422. The knob wheel 421 is a wheel body with anti-slip patterns on the outside, rotatably connected to the top of the buckle cover 3. Circumferentially distributed trigger keys 422 are arranged on the inner side of the knob wheel 421, and the trigger keys 422 are intermittently in contact with the valve plate 413 as the knob wheel 421 rotates to drive the movement of the valve plate 413.

[0040] Furthermore, the one-way cylinder 41 or the trigger key 422 is asymmetrically arranged;

[0041] Through the asymmetric setting of the one-way cylinder 41 and the trigger key 422, the driving of the one-way cylinder 41 by the trigger key 422 is a single trigger, which reduces the driving resistance, shortens the single trigger interval, shortens the trigger stroke, forms a tighter trigger rhythm, and improves the torsion feel.

[0042] Specifically, an elastic member is provided at the connection between the valve plate 413 and the air chamber 411. The elastic member acts on the valve plate 413 to keep the valve plate 413 always moving towards the partition member 412.

[0043] By using the elastic member, a reset force is provided for the valve plate 413. When the exhaust mechanism 4 is not operating, the valve plate 413 is pressed against the partition member 412 to tightly press the valve flap 4122 corresponding to the storage bottle body 5, preventing the possible sealing failure of the antibacterial liquid caused by the loose fitting of the valve flap 4122.

[0044] Specifically, the collar 1 and the buckle cover 3 are provided with limit buckles 36 with corresponding protrusions and depressions distributed circumferentially to perform circumferential limitation after the connection of the collar 1 and the buckle cover 3, improving the circumferential connection strength between the collar 1 and the buckle cover 3, and avoiding the breakage of the buckle belt 2 caused by the torsion of the buckle cover 3 and the collar 1 after the kinetic energy is transmitted to the buckle cover 3 when the rotary knob 421 is rotated.

[0045] When implementing the technical solution recorded in this embodiment, after the antibacterial liquid is used up and the buckle cover 3 is buckled, by rotating the driving knob 42 at the top, the movement of the valve plate 413 of the one-way cylinder 41 in the buckle cover 3 can be driven to drive the one-way discharge of the gas in the storage bottle body 5, reducing the air content in the storage bottle body 5, increasing the vacuum degree, slowing down the deterioration of the antibacterial liquid in the storage bottle body 5 caused by contact with air, and extending the shelf life of the antibacterial liquid after opening.
