Abstract
A vacuum pump accommodates a drip-proof dispenser so that the vacuum pump encapsulates and houses the dispenser. The same vacuum pump functions as cap to keep the vacuum pump and the dispenser on a bottle. The vacuum pump further incorporates a de-vacuuming feature, a damper feature, and anti-pinching feature while implementing a one-way valve as part of the vacuum pump.
