Metering bottle cap

Technical Field

The invention relates to the technical field of bottle caps, in particular to a metering bottle cap.

Background

The bottle cap has the functions of keeping the content sealed and keeping the content sanitary and safe, so the bottle cap is widely applied to bottled products and is a key component for packaging bottle containers.

The contents of the bottle container are often required to be taken quantitatively in daily use, for example, taking the contents of the bottle container when cooking dishes, taking the contents of the bottle container when bathing and the like can be taken within a certain range of values. Some bottled products of current often measure through the weighing hopper that is provided with the measurement scale on the bottle and get and use bottled material, its ration that can realize taking the bottle thing through the scale of weighing hopper, but the in-process of taking probably need derive or pour the bottle thing repeatedly because take too much or too little, and is comparatively troublesome. The existing Chinese patents with application numbers 201320194602.6 and 201710546825.7 all provide that when taking bottled objects, the bottle body is firstly turned over to fill the liquid storage cylinder or the metering cavity, then the communication relation between the liquid storage cylinder or the metering cavity and the bottle body is blocked, and then the bottled objects in the liquid storage cylinder or the metering cavity are taken out, so that the effect of taking the bottled objects according to the set capacity of the liquid storage cylinder or the metering cavity can be achieved, and the bottle-taking device is not easy to pollute and is simple and convenient to operate.

The above prior art solutions have the following drawbacks: although quantitative taking can be achieved by adopting the mode of the liquid storage cylinder or the metering cavity, bottled objects with different volumes cannot be quantitatively taken, and the bottled objects can only be taken according to the preset value of the liquid storage cylinder or the metering cavity, otherwise, the bottled objects need to be adjusted for many times, and therefore, the quantitative taking method has an improvement space.
