PACKING CONTAINER AND BLANK THERETO |
摘要 |
Pocking containers and packing container blanks of the type used for the packaging of e.g. milk and juice often are of the so-called gable-top type, the top closure also serving as an opening arrangement with a pouring spout which can be folded out. The parts forming the pouring spout may be coated partly with a seal-preventing substance so as to make it possible for the pouring spout to be detached and let out in spite of the heat-sealing of the top. The seal-preventing coating in accordance with the invention is covered by a film which extends along the upper edge region of the packing container , which provides a better defined sealing strength, a tighter top seal, and protects the said coating both before and after the conversion of the packing container blank to packing containers
