Definition
An overcap is the outer cap of a spray bottle, pressed or snapped over the pump once the pump has been crimped in place. The prefix says where it sits: over the closure, not instead of it.
Overcap and stopper are easy to confuse. A stopper closes a bottle that has no pump, such as a splash bottle, and is the actual seal. On a spray bottle the seal is the crimped pump, and the overcap protects the actuator from knocks and dust.
Detail and Context of Use
Packaging suppliers build overcaps in two parts, an outer shell and an inner ring that grips a collar on the bottle neck by friction. They fit crimp necks or screw necks and can be made of metal, including aluminum finished to look like heavier zamak. Decorative versions are sold as overclosures.
Weight and polish make an overcap feel luxurious, yet they say nothing about the fragrance inside.
