Abstract
An improved sealing end closure for a 'pillow' type paperboard container, according to which end flaps from opposing side panels are sealed together in a unique manner. The invention relates to a reclosable container, and more particularly relates to a pillow-shaped sealed container of paperboard or the like which is suitable for maintaining freshness of snack foods or similar items, and which can be reclosed after opening. In particular embodiments of the invention, the end closure utilizes the locking characteristics of end flaps attached to side panels by arcuate scores in a novel manner in order to provide a container which can be sealed efficiently and inexpensively, and then easily reclosed by repositioning the end flaps without the need for any additional locking mechanism. The end flaps are positioned to meet and form a seal along the transverse centerline of the container end. In one embodiment, tape is used to make the seal. In another embodiment, the seal is made with adhesive, or the container material is lined with a thermoplastic material that is heat sealed.
