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. If so, the connection between the caps is made weaker than the connection between the inner cap and bottle.
