闭口塑料容器性能试验的方法研究

闭口塑料容器一直采用桶身钻孔进行液压和气密试验，浪费较大。文章提出了在桶盖上钻孔进行液压和气密试验的方法。该方法结构简单，克服了密封等难题．每年可为全国节省试验费用百万元。

Test Method of the Closed Plastic Container

The commonly used hydraulic seal test and air-tight test for the closed plastic container need to drill a hole on the container body. After test,the container is wasted. The improved test method is to drill the hole on the cap.New method is much simple,and the hole can be easily sealed. Tt is estimated that new method can save a million yUan of test cost if it is applied broadly in the whole country.
