Filed:

Appl. No.:
6/471052
Inventors:

International Classification:

US Classification:

Abstract:
A tube of toothpaste is provided with an internal balloon or similar elastically expansable chamber near its far end, from which a slender inflation tube extends axially out of the neck and is communicated to the exterior of a cap. The cap includes a lateral projection provided with a push to close/pull to open captive closure-type valve. A valved source of compressed gas is communicated to the inflation tube. An actuator is linked both to the cap valve and to the compressed gas valve, so that as the cap valve is opened to dispense toothpaste, the compressed gas valve may be opened to pressurize and inflate the balloon within the tube. Thus the toothpaste reservoir is pressurized for dispensing. The compressed gas line to the inflation tube is provided with a safety valve incorporating a whistle. An appliance is provided housing and mounting the foregoing elements.
