Abstract
A package, particularly suited for containing viscous foodstuff, comprising a wide-mouth generally rectangular container and a dispensing closure. The closure seals onto the container with a push-on motion and includes a resealable flip-up hinged lid. The container is originally sealed, after being filled, with a seal membrane applied to the container mouth. The closure is configured to permit the seal membrane to be conveniently removed from the container mouth while the closure remains assembled on the container.
