The Principle And Standard Of Screw-on Safety Bottle Cap

The detection method of screw-on safety bottle caps and the standards related to child safety packaging started relatively late in China, and there are no relevant regulations for child safety packaging in my country at this stage. At this stage, the United States has 9 standards for child-safe packaging and gives specific requirements for some child-safe packaging rules, mainly focusing on the method of sorting child-safe packaging and the detection method of opening goose down safety packaging. Among them, ASTMD3475-1995 (2003) child safety packaging classification method classifies child safety packaging products. One of the most common packaging forms of screw-on child safety covers.

The screw-on safety bottle cap is generally made of polypropylene injection molding into the inner core, and polyethylene injection molding the outer cover of the two-piece superimposed cover. Hold the protrusions at the end of the inner cap and fit them together, and rotate at the same time, otherwise the cap will not be opened. When tightening this cap, just cover the bottle mouth and tighten it as usual. This opening method is different from ordinary bottle caps, so it can effectively prevent children from opening and mistakenly swallowing, and plays a role in safety protection for the use of medicines.
