The combination comprises a flexible container including a body portion and a neck portion. The body portion is sufficiently flexible to allow manual squeezing inwardly thereof. An amount of the liquid material is disposed within the container for storage thereof. The neck portion extends from the body portion at one end thereof to a discharge opening defined by a peripheral wall edge at the other end thereof. The sealing closure includes frangible membrane mechanism and a securing mechanism for attaching the membrane mechanism to the wall edge of the discharge opening. The sealing closure being effective to hold the liquid within the container when the container is inverted to otherwise cause the liquid therein to pour out of the discharge opening. The sealing closure has a structural configuration effective to break open causing gravitational liquid flow out of the discharge opening when the inverted container is manually squeezed inwardly.
