PRESSURE RELEASE BUTTON AND TOOL FOR PROPANE CYLINDERS

摘要

A recycling button (20) and recycling tool (150) for releasing propane from a propane cylinder (10). The recycling button (20) includes a barb (42) or other means that secures the recycling button (20) to the propane cylinder (10), thereby keeping the valve (16) of the propane cylinder (10) in an open position. The recycling button (20) is configured so that propane gas may exit the propane cylinder (10) to the atmosphere or a recycling tool (150). The recycling tool (150) aids in using a recycling button (20) and includes a diaphragm (160) attached to an indicator (162) so that any pressure exiting the propane cylinder (10) causes the diaphragm (160) to expand and the indicator (162) to show, thereby alerting users that there is still pressure inside the propane cylinder (10).
