A repressurizer for carbonated drink bottles. It comprises an internally threaded cap having a one-way valve for screwing onto the threads of a bottle neck. The pump has fastening wings for detachable attachment to the bottom of a vertically extending pump. The pump has a bottom gasket for making an air-tight seal with the cap. A modification is to eliminate the fastening wings and have the pump slip fitted or screw threaded to the cap. A still further modification is to reduce the top diameter of the cap and provide threads that can be screwed onto a bicycle or automobile pump.
