Abstract
A one-piece housing defines a pair of laterally separated chambers for containing liquids to be dispensed. A pair of hollow filler necks extend upwardly from the top wall of the housing for communication each with a different one of the chambers for filling the latter with a liquid, and a carrying handle is secured to and extends laterally between said necks. A squeeze bulb type pump associated with each chamber has an intake pipe extending into the chamber and is removably closed by a ball check valve. A flexible outlet dispenser tube extends from the valve body and is fitted at its outer end with a check valve for allowing flow of liquid only in the outfeed direction. The ball check is moved from the closed position by partial vacuum created by expansion of the bulb following squeezing, and the ball check is closed during collapsing of the bulb as it is squeezed. A threaded plunger on the ball check valve body also is movable into abutment with the ball to secure the latter in closed position during transport and storage of the container. The squeeze bulbs are confined in depressions formed in the top wall of the container housing.

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.
