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

Abstract

The invention discloses an eye drop packaging bottle which comprises a bottle body, a dropping pipette and a bottle cap. A piston assembly is connected in the bottle body in a sliding mode and comprises a piston body and a piston rod. Outer threads are formed on the piston rod. A one-way pushing groove is formed in the piston rod. The bottle body is connected with a nut part. Inner threads are formed on the inner wall of the nut part. A first clamping head is formed on the nut part, and a clamping opening is formed in the bottle body. A pushing block groove is formed in the outer wall of the upper portion of the nut part. A pushing block assembly is connected in the pushing block groove in a sliding mode and comprises a pushing block, an elastic plate and a pushing plate. A second clamping head is formed on the pushing block, and a strip-shaped clamping opening is formed in the pushing groove. An elastic plate inlet-outlet is formed in the pushing groove. Two spring grooves are formed on the pushing block. Springs are installed in the spring grooves. The pushing block groove is connected with a spring positioning column. Both the bottle body and the cap body can be respectively and integrally formed by plastic, and the eye drop packaging bottle is convenient to manufacture and low in cost.

Description

technical field [0001] The invention belongs to the field of eye drops packaging bottles. Background technique [0002] Existing 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an eye drop bottle with a reasonable and simple structure, which will not significantly increase the production cost compared with ordinary eye drop bottles. [0004] Aiming at the deficiencies in the prior...
