ABSTRACT:
The container of this invention is accordion-pleated and is provided in a collapsed condition for normal shipment. Just prior to use, one end of the container is opened and filled with water. Powder or a tablet is usually provided in the container for mixing with water. The cover of the closure has an air valve which includes a ball, slightly spring loaded, and a closure valve contained in a remotely carried nozzle attachment. This valve is manipulated to an open condition and is closed by pressure on the extending wing or flanged portions of the valve. The closure end of the container is preferably connected by flexible tubing to the valve which is also secured to the nozzle.
