ABSTRACT A dispenser serves to inject an edible viscous material such as mayonnaise, cream or the like at a constant rate after it is once contained in a cartridge (26). The dispenser includes a storing portion (2) in which a cylindrical inner case (30) having a bottom is stored. The cylindrical inner case (30) is dimensioned to have a length long enough so as to allow a shoulder portion of the cartridge (26) to be exposed to the outside via an opening portion at one end thereof. An insert hole (31) is formed on the bottom of the cylindrical inner case (20) at the other end of the latter so as to enable a rod (22) to be inserted therethrough. The cartridge (26) and an extrusion plate (21) are received in the cylindrical inner case (30) so that the extrusion plate (21) can smoothly be displaced in the storing portion (2). A pawl member (8) disposed in a trigger (4) and a stopper (15) disposed in a main body (1) of the dispenser are brought in meshing engagement with a gear wheel assembly (10) mounted on a support shaft (5) for the trigger (4) in the coaxial relationship. In addition, a rod (22) adapted to be reciprocably displaced in the storing portion (2) is brought is meshing engagement with the gear wheel assembly (10). A guide (19) adapted to be displaced slidably relative to the pawl member (8) is disposed on the main body (1) side in such a manner that it is disengaged from the gear wheel assembly (10) when the trigger (4) is restored to the original position. - 29 -
