[0002] Eye drop bottle is a device used to store eye drops. Eye drops are sterile liquid preparations made of raw materials and suitable excipients for instillation into the eye. They are widely used in clinical practice. Due to the special application site of eye drops, their quality and safety are also subject to higher requirements than ordinary preparations, and they must achieve a sterile effect.

[0003] At present, the product structure of ordinary eye drop bottles on the market is simple and the function is single. It is mainly composed of three parts: an outer cover, an inner plug and a bottle body. However, eye drops are sterile liquid medicines made of raw materials and appropriate excipients that are dripped into the eyes, and ordinary eye drop bottles can only be used within a limited period of efficacy once they are opened and used. Specifically, ordinary eye drop bottles cannot block bacteria and oxygen. After opening and using, on the one hand, it is easy for liquid medicine to remain at the mouth of the inner plug. The residual liquid medicine will quickly breed bacteria or be oxidized in a moist environment, and then directly contaminate the eye drop liquid in the bottle body through the straight inner plug hole; at the same time, due to the poor sealing between the outer cover and the bottle body, air can easily enter the bottle body, causing the liquid medicine to be contaminated and breed bacteria due to contact with air, and become ineffective. Therefore, the quality, safety and efficacy of the currently available ordinary eye drop bottles are relatively low. Utility Model Content

DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] Reference Figure 1-6 As shown, the antibacterial and anti-oxygen eye drop bottle of the utility model comprises: an outer bottle body 1, an inner bottle body 2, an elastic ring 3, a support plug 4, an inner plug 5 and an outer cover 6; the outer bottle body 1 is arranged at the outermost layer of the eye drop bottle, and the material of the outer bottle body 1 is PP material; the inner bottle body 2 is arranged inside the outer bottle body 1, and the material of the inner bottle body 2 is LDPE material, the inner bottle body 2 and the outer bottle body 1 form an inner and outer double-layer bottle structure, and a gap is provided between the outer wall of the inner bottle body 2 and the inner wall of the outer bottle body 1; the elastic ring 3 is sleeved on the outer wall of the bottle mouth of the inner bottle body 2, and the elastic ring 3 is located between the bottle mouth of the outer bottle body 1 and the inner bottle body 2; a support plug 4, which is arranged in the bottle mouth of the inner bottle body 2, and the material of the support plug 4 is LDPE material, and the support plug 4 is provided with a plurality of through holes 40 connected with the interior of the inner bottle body 2, and a filter membrane is applied on the upper end surface of the support plug 4, and the filter membrane is a hydrophilic filter membrane, and the filter membrane is used to pass liquid while isolating air; an inner plug 5, which is covered on the end of the support plug 4 extending out of the bottle mouth of the inner bottle body 2, and the material of the inner plug 5 is LDPE material; an outer cover 6, which is connected to the bottle mouth of the outer bottle body 1, and the inner plug 5 is located in the inner cavity covered by the outer cover 6, and the material of the outer cover 6 is PP material.

[0033] Preferably, the filter membrane uses a hydrophilic filter membrane with a pore size of less than 0.22um. When the filter membrane is soaked, the filter membrane can prevent air from entering the inner bottle but liquid can pass through the filter membrane. Since the pore size of the filter membrane is less than 0.22um, bacteria can be prevented from entering the inner bottle.

[0034] Reference Figure 7 As shown, an annular boss 21 is provided on the circumferential outer wall of the bottle mouth of the inner bottle body 2, and one end of the elastic ring 3 close to the bottle mouth of the inner bottle body 2 abuts against the annular boss 21.

[0035] Reference Figure 8 , 9As shown, the support plug 4 includes a plug body 41 and a support plate 42. The plug body 41 is arranged in the bottle mouth of the inner bottle body 2. The support plate 42 is connected to one end of the plug body 41 extending out of the bottle mouth of the inner bottle body 2, and the support plate 42 is in contact with the end surface of the bottle mouth of the inner bottle body 2. A through hole 2 421 is arranged at the center of the support plate 42. The plurality of through holes 1 40 are arranged on the support plate 42, and the plurality of through holes 1 40 are evenly distributed around the through hole 2 421. The filter membrane cover is arranged on the through hole 2 421 and the plurality of through holes 1 40. A liquid inlet hole 411 is arranged on the plug body 41, and the liquid inlet hole 411 is connected with the through hole 2 421 and the plurality of through holes 1 40.

[0036] Reference Fig.10 , 11 As shown, a slot 51 is provided at one end of the inner stopper 5 close to the mouth of the inner bottle body 2, and the outer edge of the support plate 42 is arranged in the slot 51. A conical surface 1 52 is provided on the outer wall of the inner stopper 5, and an annular boss 2 11 is provided on the inner wall of the mouth of the outer bottle body 1, and the lower end of the annular boss 2 11 is set as a conical surface 2 111, and the conical surface 1 52 contacts with the conical surface 2 111 to form a sealing surface. An arched convex portion 53 is provided at the center of the inner stopper 5, and a drip hole 531 is provided at the center of the arched convex portion 53. A plurality of liquid guide sheets 54 are provided on the inner wall of the inner stopper 5, and the plurality of liquid guide sheets 54 are arranged in a circular array with the drip hole 531 as the center, and the plurality of liquid guide sheets 54 are arranged at intervals.

[0037] Reference Fig.12 As shown, an annular convex portion 3 61 is provided on the bottom surface of the inner groove of the outer cover 6, and the inner diameter of the annular convex portion 3 61 is greater than the maximum outer diameter of the arched convex portion 53. When the outer cover 6 is covered on the outer bottle body 1, the arched convex portion 53 is located in the inner cavity surrounded by the annular convex portion 3 61, and the annular convex portion 3 61 can press the inner plug 5 downward when the outer cover 6 is buckled, and the inner plug 5 squeezes the inner bottle body 2 through the support plug 4, and the inner bottle body 2 drives the elastic ring 3 to be compressed. At this time, the conical surface 1 52 is separated from the conical surface 2 111, so that the gap between the outer wall of the inner bottle body 2 and the inner wall of the outer bottle body 1 can communicate with the outside. An arc-shaped convex portion 62 is provided at the center of the bottom surface of the inner groove of the outer cover 6, and the arc-shaped convex portion 62 is used to block the drip hole 531 when the outer cover 6 is buckled.

[0038] Reference Figure 7 As shown, the elastic ring 3 is in a circular ring shape, and a plurality of notches 31 are provided on the lower end of the elastic ring 3 . The material of the elastic ring 3 is silicone.

[0039] During use, after the outer cover 6 is opened, since there is no downward pressure on the elastic ring 3 by the outer cover 6, the elastic ring 3 eliminates the pressure and returns to its original state, and the elastic ring 3 drives the inner bottle body 2 to move upward, so that the conical surface 1 52 contacts the conical surface 2 111 to form a sealing surface. At this time, a closed space is formed between the outer bottle body 1 and the inner bottle body 2, and the outer bottle body 1 is squeezed. Since the outer bottle body 1 and the inner bottle body 2 are sealed, the air pressure will transfer the pressure to the inner bottle body 2. Under the action of the pressure, the liquid in the inner bottle body 2 drips outward through the filter membrane, forms water droplets through the drip hole 531 and drips, completing the drug administration.

[0040] When the medication is completed, the pressure on the outer bottle body 1 is removed and the shape of the outer bottle body 1 returns to its original shape. At this time, there is a negative pressure between the outer bottle body 1 and the inner bottle body 2. The liquid between the drip hole 531 on the inner plug 5 and the filter membrane flows back into the inner bottle body 2 through the filter membrane due to the negative pressure. The filter membrane prevents bacteria and oxygen from entering the inner bottle body 2.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
