Abstract
Abstract The invention is directed to disposable dispensing apparatus having a generally triangular body, for dispensing a material therefrom. A stop is disposed within the body, and has a variable thickness. The stop is positioned so that a user of the apparatus may squeeze opposing sides of the body at varying points to dispense varying amounts of the material. Preferably, indicia, such as frets, are disposed on the exterior of the body, to advise the user of the amount of material dispensed by squeezing the body at varying points along the stop. In a preferred embodiment, the body includes a one-way valve for permitting the influx of ambient air into the body after the dispensing of material therefrom, thereby maintaining the volume within the body at a relatively constant level. In a second preferred embodiment, the apparatus further includes a removable nozzle for locating a precise location into which the material is deposited upon exiting the apparatus. The nozzle may include a second one-way valve for preventing reflux into the body.
