Description

Extraction formula liquid preparation measurement bottle lid

Technical Field

The utility model relates to a liquid container structure field, in particular to structure field of lid that cooperation liquid container used specifically is an extraction formula liquid preparation measurement bottle lid.

Background

The liquid preparation is a common pharmaceutical dosage form in clinical medication, such as syrup, solution and the like. The existing commonly used container is a glass bottle or a plastic bottle with a common cover, and only has the function of simple sealing.

The container with scales can represent the capacity of the liquid preparation, but the control of the discharge amount is not directly helpful, and the liquid preparation is measured by other measuring instruments, so that the liquid preparation has little measuring function, on one hand, the container is relatively troublesome, needs to be repeatedly increased and decreased, cannot finish the pouring of a certain amount of the liquid preparation by one action, and is more accurate in requirement, and the method is more difficult to realize; on the other hand, the waste caused by the residual liquid preparation can be caused, and the secondary pollution is easy to cause.

A metering bottle cap is adopted, and is required to be unscrewed from a containing container during use, liquid preparation in the container is poured into the metering bottle cap, and the metering bottle cap is screwed on after use. The method has the advantages of multiple steps, troublesome use, unsanitary and easy residue of the liquid preparation in the bottle cap.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the weak point that above-mentioned prior art exists, provide a liquid preparation bottle lid that has both had sealed function, can measure again, it has simple structure, convenient to use to can realize the advantage of large-scale production manufacturing.

The utility model provides an extraction type liquid preparation measuring bottle cap, which is characterized in that the bottle cap comprises a lower cover, a volumetric cylinder and a piston rod arranged in the volumetric cylinder; the lower cover is sleeved on the volumetric cylinder and used for sealing the bottle mouth; the outer wall of the piston rod is in seamless contact with the inner wall of the volumetric cylinder, and the piston rod can move up and down in the volumetric cylinder to form a piston structure; the lower end of the volumetric cylinder is provided with a cylinder nipple for extracting the liquid preparation; the volumetric cylinder is provided with volumetric scales for marking the volume of the liquid preparation in the volumetric cylinder.
