Abstract
A device suited for dispensing a dental substance comprises a cartridge 20 or receiving the substance, with a curved dispensing nozzle 22 disposed at the front end and a flange 21 of octagonal cross-section provided at the rear end of the cartridge. The flange 21 serves to engage a slide-in socket 16 of an applicator 10 which includes a piston rod 12 for advancing a dispensing piston 23 disposed in the cartridge 20. In the retracted position of the piston rod 12, the cartridge 20 may be laterally inserted into the slide-in socket 16 of the applicator 10. The socket has two parallel walls spaced by a distance which is between the largest and the smallest diameter of the octagonal flange 21. The material of the flange 21 and/or the material forming the slide-in socket 16 is resilient so that the cartridge 20 may be stepwise rotated about the axis of the piston rod 12 with respect to the applicator 10 without requiring the piston rod 12 to be withdrawn and the cartridge 20 to be removed from the slide-in socket and re-inserted in a new orientation.
