发明名称 A RESEALABLE CLOSURE FOR A BAG
摘要 A resealable closure for a bag is described wherein the bag has upper and lower ends and including a front wall member, a back wall member, and opposite sid e wall members. The lower end of the bag is sealed in conventional fashion. The upp er ends of the wall members are folded downwardly adjacent the front wall member to form a flap which extends across the upper end of the bag with the upper flap being permanently sealed, by an adhesive, to the front wall member except for a fl ap portion adjacent one of the side wall members. The resealable closure is positioned between the flap portion and the front wall of the bag and permits the flap portion to be opened to form a pour opening in the upper corner of the bag. The flap portion may be resealed by the resealable closure. The closure is designed so that the contents of the bag will not come into contact with any sticky or tacky surface as the material is being poured from the bag.
