OPENING ARRANGEMENT ON PACKING CONTAINERS AND A METHOD FOR THE MANUFACTURE OF THE SAME |
摘要 |
<p>Opening arrangements for packing containers often comprise a prepunched hole which is covered by a tear-off cover strip. To facilitate the pouring out of liquid contents a so-called pouring rim is frequently present too, that is to say a material strip which forms a projecting rim over which the contents can run. The application of the pouring rim as well as the manufacture of the opening arrangement as a whole are facilitated by joining in advance the pouring rim in a detachable manner to the cover strip, whereafter the cover strip and the pouring rim can be applied as a unit.</p> |
