• a bladder for holding liquid including a bladder top, a bladder base and a bladder upper spout locknut positioned inside the bladder;
• and
• a spout having a spout body with a connecting end that is attachable to the upper spout locknut for attaching the connecting end of the spout to the bladder, an internal liquid flow path extending from the connecting end to a liquid outflow port and a release button for enabling liquid flow through the internal liquid flow path and out the liquid outflow port;
• wherein the spout is removably attached via first threads to the upper spout locknut to connect the spout to the bladder,
• wherein a spout flange positioned between the spout and the bladder facilitates connecting the bladder and spout to the bottle top;
• wherein detaching the first bottle part from the second bottle part enables access to the bottle internal volume, into which the bladder is inserted into the bottle inner volume or removed from the bottle inner volume;
• and
• wherein actuating the release button opens a liquid flow for the liquid present in the bladder to flow through the spout at the top of the bottle.
