  • Patent number: 5114013
    Abstract: This invention relates to a reclosable sealing carton with a thin polymeric coating. The package is characterized by an extended glue flap scored with a cut-out adapted to form a plug when adhered to the underside of a closure flap and a closure flap overlying the glue flap cut-out of the material of the closure flap. When the consumer opens the closure flap, the cut-out in the glue flap adheres to the closure flap thereby forming a reclosable plug. The closure also comprises a thin, top coating applied to the closure to provide increased durability and resistance to wet handling. The reclosable flap may further comprise a tab facilitating ease of lifting the closing and a recess cut-out of the side panel overlying the glue flap also facilitating ease of lifting.
