专利汇可以提供Method of forming, filling and closing cartons, and specific cartons therefor专利检索，专利查询，专利分析的服务。并且This disclosure is directed to a novel method of forming, filling, covering and sealing a carton which includes a bottom panel, four upstanding side panels, and a minor flange joined to each of the side panels, a product is packaged within the carton body, and a cover which preferably is post-scored but may be prescored is applied thereto and includes four major flanges, one overlying each of the minor flanges of the carton body, the method including the steps of deflecting the minor and major flanges relative to each other to provide an area for the receipt of a hot-melt adhesive, thereafter applying pressure to unite the flanges, and subsequently securing the adhered flanges to the carton side panels. The covers may be individually fed from a stack of blanks, severed from a web drawn from an appropriate roll or as another alternate the carton body and cover would be of an integral one-piece construction. From a carton standpoint both the carton and cover are preferably coated on each side with an over-all barrier coating of moisture impervious material and minor-flange to major-flange adhesion as well as adhesion of the latter flanges to the side panels is preferably though not exclusively achieved by the use of in-line applied hot-melt adhesives, although adhesive precoating may be employed along with other adhesives or equivalents.，下面是Method of forming, filling and closing cartons, and specific cartons therefor专利的具体信息内容。
