A closure cap assembly for a container having a spout, comprising: a spout adapter comprising: a tubular body portion having a proximal end, a distal end, an external surface, and an internal surface defining a flow passage extending through the body portion from the proximal end to the distal end, the body portion configured to be fixed to the spout of the container; and a pull portion positioned in the flow passage of the body portion and having a proximal end and a distal end, wherein the pull portion has a length such that the distal end extends beyond the distal end of the body portion; and a cap having a top end and a bottom end, the cap connected to the external surface of the body portion and connected to the pull portion in a way that the pull portion separates from the body portion as the cap is removed from the body portion; the closure cap assembly being characterized in that the proximal end of the pull portion is connected to the body portion to form a seal across the flow passage between the proximal end and the distal end of the body portion; in that the pull portion is generally cylindrically shaped and positioned in the flow passage of the body portion in a coaxial relationship to the body portion; and in that the cap 18 is threadingly connected to an external surface of the body portion, the cap being connected to the pull portion in a way that the distal end of the pull portion extends beyond the top end. a spout adapter comprising: a tubular body portion having a proximal end, a distal end, an external surface, and an internal surface defining a flow passage extending through the body portion from the proximal end to the distal end, the body portion configured to be fixed to the spout of the container; and a pull portion positioned in the flow passage of the body portion and having a proximal end and a distal end, wherein the pull portion has a length such that the distal end extends beyond the distal end of the body portion; and a tubular body portion having a proximal end, a distal end, an external surface, and an internal surface defining a flow passage extending through the body portion from the proximal end to the distal end, the body portion configured to be fixed to the spout of the container; and a pull portion positioned in the flow passage of the body portion and having a proximal end and a distal end, wherein the pull portion has a length such that the distal end extends beyond the distal end of the body portion; and a cap having a top end and a bottom end, the cap connected to the external surface of the body portion and connected to the pull portion in a way that the pull portion separates from the body portion as the cap is removed from the body portion; the closure cap assembly being characterized in that the proximal end of the pull portion is connected to the body portion to form a seal across the flow passage between the proximal end and the distal end of the body portion; in that the pull portion is generally cylindrically shaped and positioned in the flow passage of the body portion in a coaxial relationship to the body portion; and in that the cap 18 is threadingly connected to an external surface of the body portion, the cap being connected to the pull portion in a way that the distal end of the pull portion extends beyond the top end.
