Abstract
A mixer for dental capsules has a fork-type capsule holder which includes a pair of rigid arms (1, 2) one of which is provided with a pin (10) that passes through an opening (11) provided in the other arm (1). A helical spring (13) disposed about the pin (10) creates a tilting moment about the capsule holding location which causes the pin (10) to be caught by edges forming the opening (11), thereby producing a self-locking action which is not released during the mixing movement. For inserting and removing a capsule (5) in the inoperative condition of the mixer, the fork may be readily opened by pulling a handle (16) provided on the one arm (2) against the relatively weak force of the spring (13).
