The adapter has a body which is sealingly threadedly engaged with the drum and has a cap which is threadedly engaged with it. An adapter fitting has a bore therethrough connecting the adapter body to the tubing, and further has a connecting device for a quick-connect fitting. The foot valve has a body with a check valve which permits flow of chemicals only from and not into the drum. A foot valve connects the foot valve body to the tubing. A quick-connect fitting that is normally closed is adapted to engage the adapter by a spring-loaded ring which interacts with a recess. A manually operated release mechanism for the ring is connected thereto.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
