发明名称 Method of making a semi-rigid cereal carton
摘要 A paperboard container of generally semi-rigid construction and formed from a unitary blank of paperboard folded in the general shape of a U. The interior surface of the container is coated with a thermoplastic polymer barrier layer, the container having a manually openable, normally closed pour spout at one upper edge portion, and also having a recessed or raised bottom. The container is particularly adapted for packaging granular, dry material such as corn flakes, pretzels, and the like. Due to its construction and the thermoplastic barrier layer, the usual inner pouch which contains dry cereal is omitted, thereby effecting savings in both material and in assembly of the final package. In one embodiment, an opening is provided for carrying the package, the opening located at the top of the container. In another embodiment one side wall of the panel is provided with an extension to serve as a reclosure flap.
