Abstract: A dual cap dispenser has an inner cap connected to a bottle and an outer cap is detachably connected to the inner cap. There is a longitudinally extendable bellows-like tube connected to the inner cap and having an outer end closed by the outer cap. Preferably, the bellows-like tube is semi-rigid and comprises three stable states. A first state has the sides of a fold of the bellows collapsed against each other. A second state has the sides of the fold spaced apart from each other when the tube is extended. The third state has a fold on one side of the tube collapsed while the same fold on the diametrically opposite side of the tube is expanded, thereby providing an opportunity to have a curved dispensing tube. The inner cap is threaded on the bottle and the outer cap is connected to the inner cap by a bayonet fitting or similar "quick release" arrangement. Tamper evident connections may be made between the inner and outer caps, and between the inner cap and the bottle.
