ABSTRACT:
A dispenser, such as a syringe or the like, is disclosed for dispensing liquids or other fluid material. A generally tubular side wall has closed lower and upper ends with discharge means in the upper end. The tubular side wall is formed by a plurality of spiral ribs for twisting and collapsing the dispenser about its longitudinal axis to dispense the fluid material therefrom through the discharge means. The spiral ribs extend into and through the closed ends of the dispenser to facilitate dispensing substantially the entire material therefrom by twisting action of the dispenser. The ribs have generally flat outer surfaces separated by V-shaped grooves whereby when collapsed the dispenser forms a substantially stable handle with the flat outer surfaces disposed in substantially side-by-side abutment. The dispenser is formed as an integral molded and prefilled construction, including a frangible cap on a threaded neck which forms the discharge means. A valve construction also is disclosed for use with a syringe nozzle.
