Abstract
A dispensing adapter for connecting pressurized containers to other valved systems such as automobile air conditioners is provided. The housing has a dispensing end, a receiving end, and an interior volume communicating between the dispensing end and the receiving end. The receiving end sealingly engages a first valve of a pressurized container, and the dispensing end sealingly engages a second valve such as a service port of an automobile air conditioner. A reciprocatable core depressor is disposed inside the housing. When dispensing end is attached to the service port, the core depressor is moved toward the receiving end of the housing, and the proximal end of the core depressor engages a stem of the first valve and opens the first valve. The housing maybe angled or straight, and the core depressor may have a piercing pin to open puncture valve containers.
