Abstract
A pour spout closure is provided having a base section and a cover section hingedly mounted thereon for selective movement between open and reclose positions. The base section is affixed to a surface of a container and in proximity to an opening formed in such surface. The base section has formed therein a dispensing aperture which is exposed when the cover section is in an open position. The dispensing aperture is in registered relation with the container opening. A flap, connected to a portion of the base section circumjacent the dispensing aperture, is folded relative thereto whereby a peripheral portion of the flap is adjacent the perimeter of the container opening. The cover section is provided with a protuberance which is sized to extend into the container opening when the cover section is in a reclose position. A predetermined exterior portion of the cover section protuberance is yieldably engaged by the flap peripheral portion when the protuberance extends into the container opening.
