Quantitative liquid outlet bottle cover

Abstract

The invention provides a quantitative liquid outlet bottle cover. The quantitative liquid outlet bottle cover comprises a bottle cover body and a cylinder, wherein the upper end of the bottle cover body is rotatably connected with the lower end of the cylinder through a connection cap; a liquid outlet hole penetrating through the upper end of the bottle cover body and the connection cap is formed in the bottle cover body and the connection cap; a baffle plate is arranged at the bottom of the cylinder; a sealing ring is arranged between the baffle plate and the cylinder; a liquid inlet hole is also formed in the position, corresponding to the liquid outlet hole, of the baffle plate; a fixed blocking piece, a sliding blocking piece and a rotating shaft arranged in the length direction of the cylinder are arranged in the cylinder; the rotating shaft adopts a hollow structure, and a position adjusting rod is arranged in the rotating shaft; the lower end of the position adjusting rod is fixed to the baffle plate, the upper end of the position adjusting rod extends out to the outer side of the end of the rotating shaft, and the upper end of the rotating shaft penetrates through the upper end of the cylinder and extends to the outer side of the cylinder; and a rotary knob with a pointer is arranged at the upper end of the rotating shaft. The quantitative liquid pouring is realized by taking the bottle cover as a starting point, and the bottle cover can realize standardized production and can be repeatedly used for many times for different bottles. The quantitative liquid outlet bottle cover belongs to the field of quantitative fluid obtaining.

Description

technical field [0001] The invention relates to a bottle cap, which belongs 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 bottle body is high, and ...

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.
