Bottle cap capable of quantitatively pouring out liquid and application method thereof

Abstract

The invention provides a bottle cap capable of quantitatively pouring out liquid and an application method thereof; the bottle cap comprises a bottle lid and a cylinder; the bottle lid top is fixedly provided with a connecting cap, and rotatably connected with the cylinder bottom through the connecting cap in a sealing manner; the bottle lid and the connecting cap are provided with a liquid outlet connecting the bottle lid top with the connecting cap; the cylinder bottom is provided with a liquid inlet matched with the liquid outlet; a fixed stop plate, a slide stop plate and a rotary shaft arranged in the cylinder length direction are arranged in the cylinder; the rotary shaft top penetrates the cylinder top and extends outside the cylinder, and is provided with a rotary button with a pointer; the cylinder top outer wall is engraved with scales in the circumference direction of the rotary button; the cylinder top is also provided with a through hole capable of being closed; the bottle cap serves as the start point so as to quantitatively pour out the liquid; the bottle cap can be standardized in production for different bottle bodies, and can be repeatedly used; the bottle cap and application method thereof belong to the liquid quantification field.

Description

technical field [0001] The invention relates to a bottle cap and a using method thereof, belonging to the field of liquid quantitative pouring. Background technique [0002] When people are sick, it is inevitable to take medicine. When taking medicine, it is often necessary to take some liquid medicines, and the doses of these medicines are stipulated for each taking, and should not be too much or too little. At present, because it is difficult for the patient to judge the dose of the medicinal liquid poured out each time with the naked eye and experience, a small measuring cup is prepared in the medicine box. This measuring cup is often used as a disposable measuring cup. When the liquid medicine is used up, the measuring cup becomes plastic waste, which not only increases the cost, but also causes waste of resources and environmental pollution. In order to solve this problem, there are currently many inventions to improve the bottle body, but the cost of improving the bo...

Problems solved by technology

This measuring cup is often used as a disposable measuring cup. When the liquid medicine is used up, the measuring cup becomes plastic waste, which not only increases the cost, but also causes waste of resources and environmental pollution.

In order to solve this problem, there are currently many inventions to improve the bottle body, but the cost of improving the bottle body is high, and there are various types of bottle bodies. The process of improving the bottle body is complicated, and it is difficult to truly realize industrial production.
