Description

technical field [0001] The invention relates to the field of bottle packaging, more specifically, it relates to a rotary injection type bottle cap. Background technique [0002] With the improvement of people's living standards, people have put forward higher and higher requirements for the safety and health of drinks. For bottled beverages, in order to prolong the shelf life, it is necessary to add preservatives, preservatives, stabilizers and other ingredients harmful to human health. Before use, nutritional ingredients are isolated from water, ready to use and ready to use, avoiding the use of additives.

AI Technical Summary

Problems solved by technology

Although this kind of bottle cap separates the solution from the solution, when the top of the bottle cap body is pierced, the part of the top of the bottle cap body easily falls into the bottle, causing foreign matter to appear in the mixed drink and affecting the drinking of the drink; The piercing opening of this piercing method is small, which will cause larger particles (such as wolfberry) to block the piercing opening and cannot fall into the bottle, and it is easy to have residual blended materials on the bottle cap, and then puncture by pressing The form of the top of the bottle cap body is easy to accept external extrusion during the transportation or storage of the bottle cap, which may accidentally puncture the top of the bottle cap body, affecting normal use
