Abstract
A pour spout closure of unitary construction is provided for mounting on the surface of a container and in proximity to an opening formed therein. The closure includes a base section having portions attached to the container surface. Foldable flaps are affixed in a folded relation to portions of the base section which are disposed on opposite sides of the container opening. Peripheral segments of the folded flaps are disposed proximate the perimeter of the container opening. Hingedly connected to the base section is a cover section which is selectively moveable between open and close positions. The cover section is provided with a protuberance sized to enter the container opening when the cover section is in a reclose position. A laterally extending rim is provided on the cover section which encompasses an exposed surface of the protuberance. Peripheral segments of the flaps are yieldable and frictionally engage the cover section and retain same in the reclose position.
