Container closure apparatus including a rigid container having an open end with a top edge along a collapsible container disposed within the rigid container and having an open end. A cap is provided for covering the rigid and flexible container open ends and a plug seal providing a primary seal between the rigid container and the flexible container. The plug seal includes, in combination, a peripheral outwardly extending wall portion on the flexible container and a depending portion, extending from the cap, for pressing the wall portion against an inside wall of the rigid container. An annular node formed into the flexible container wall provides concentrate sealing pressure between the cap depending portion, the wall portion and the inside wall of the rigid container. A gasket seal provides a secondary seal between the rigid container and the flexible container. The gasket seal includes, in combination, a lip outwardly extending from the flexible container open end and a groove, disposed in the cap means, for pressing the lip against the rigid container top edge. The cap is secured to the rigid container in a position enabling the depending portion means to press the extending wall against the rigid container inside wall and enabling the groove means to press lip against the rigid container top edge.
