Eyedrops packaging bottle

Abstract

The invention discloses an eyedrops packaging bottle. The eyedrops packaging bottle comprises a bottle body, a dropping pipette and a bottle cap. A pressing assembly is connected between the bottle body and the dropping pipette. A pipe cavity in the pressing assembly is matched with a conical pipe part on the bottle body, so a check valve structure is formed at an opening of the conical pipe part. Two clamping plates on the pressing assembly are matched with a clamping part of the dropping pipette to form a pressure-limiting valve structure. In this way, the opening of the conical pipe part is in a stopped state after the pressing part is extruded by fingers, eyedrops produce pressure on the inner wall of the clamping part to force the clamping part to be communicated, and therefore the eyedrops can flow out of the dropping pipette. After extrusion on the pressing part by the fingers is released, the pressing part restores to an initial state due to self material elasticity, at this time, the opening of the conical pipe part is communicated due to the action of negative pressure, and therefore the eyedrops in the bottle body flow into the pipe cavity.

Description

technical field [0001] The invention belongs to the field of liquid medicine containers, and in particular relates to the structure of an eyedrop packaging bottle. Background technique [0002] Existing eye drops bottle mostly adopts the bottle body of plastic material, presses bottle body side by finger during use to make eye drops drop out from the drip tube that is connected to bottle opening. However, due to the poor control of the strength of the squeeze bottle, many drops may be squeezed out at one time and part of the eye drops will overflow the eyes. In addition, the dosage of some eye drops must be controlled within a certain range. For a long time, side effects may occur and accidental damage to the eyes may occur. In addition, after the eye drops bottle is opened, the air will enter the eye drop bottle, and the bacteria and viruses in the air will also enter, which will affect the storage time of the eye drops.

Problems solved by technology

However, due to the poor control of the strength of the squeeze bottle, many drops may be squeezed out at one time and part of the eye drops will overflow the eyes. In addition, the dosage of some eye drops must be controlled within a certain range. Over time, side effects may occur and accidental damage to the eyes may occur

In addition, after the eye drops bottle is opened, the air will enter the eye drop bottle, and bacteria and viruses in the air will also enter, which will affect the storage time of the eye drops.

The Chinese patent No. 2010206686286 discloses a quantifiable eye drop bottle device, which can squeeze out eye drops quantitatively by setting two valve switches and matching the scale on the bottle body, and can also be avoided by proper operation. Air enters the bottle body, but the technical solution of this patent is only an idea. The introduction of the valve switch will greatly increase the number of parts of the eye drop bottle, and the assembly is troublesome, which will undoubtedly greatly increase the production cost
