Eye drop bottle

Abstract

The invention belongs to the technical field of liquid containers, and particularly relates to an eyedrop bottle which comprises a liquid storage bottle and an inner bottle cap, a bottle body of the liquid storage bottle can be extruded to deform, the inner bottle cap is connected to the upper end of the liquid storage bottle and forms a cavity with the liquid storage bottle, a liquid outlet communicated with the cavity is formed in the upper end of the inner bottle cap, an elastic body is arranged in the inner bottle cap, and a sealing part is arranged at the upper end of the elastic body. An air inlet hole is formed in the inner bottle cap and / or the liquid storage bottle, an air filtering device and a one-way air inlet device are arranged between the air inlet hole and the cavity, when the bottle body of the liquid storage bottle is extruded, liquid in the cavity extrudes the elastic body and the sealing part to move towards the side away from the liquid outlet hole, and the liquid outlet hole is communicated with the cavity; when the liquid storage bottle body is loosened, the elastic body is reset, and air enters the cavity through the air filtering device and the one-way air inlet device. The eyedrops are slowly and uniformly discharged from the eyedrops outlet holes, so that the waste of the eyedrops is effectively reduced; meanwhile, residual eyedrops in the eyedrops outlet holes cannot flow back, external air enters the cavity after being filtered, deterioration of the eyedrops is effectively delayed, and the service life of the eyedrops is prolonged.

Description

Technical field: [0001] The invention belongs to the technical field of liquid containers, in particular to an eye drops bottle. Background technique: [0002] Eye drops are one of the most commonly used pharmaceutical dosage forms for eye diseases. For many eye diseases, eye drops have direct and quick therapeutic effects. [0003] Chinese utility model patent CN214181116U discloses a squeeze-type eye drops bottle, which includes a bottle body, a bottleneck and a bottle mouth. The inside of the body and the bottle mouth are all connected to the spray hole, the bottom wall of the bottle seat is provided with several buckle components in the circumferential direction, and the top wall of the bottle neck has several buckle components for corresponding The outer diameter of the bottle mouth is smaller than the outer diameter of the bottle seat, the outer diameter of the bottle seat is smaller than the outer diameter of the bottle neck, and the bottle neck is threaded with a se...

Problems solved by technology

[0004] The disadvantages of the above-mentioned eye drops bottle are: 1. The eye drops bottle is pinched by hand, and the pressure in the bottle increases so that the eye drops are directly extruded from the bottle mouth. It is easy to cause the eye drops to be sprayed due to excessive outlet pressure, which will cause other diseases or discomfort in the patient, and at the same time lead to excessive instillation of eye drops, especially for some expensive eye drops, the waste of eye drops will increase the treatment cost for patients; 2. After use, the eye drops remaining in the bottle mouth that has been in contact with the air will flow back into the bottle, polluting the eye drops in the bottle; 3. After use, the air will be directly sucked into the bottle through the bottle mouth to balance the pressure inside and outside the bottle , the air entering the bottle will pollute the eye drops in the bottle
