Patent number: 5375740Abstract: 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).Type: GrantFiled: February 19, 1993Date of Patent: December 27, 1994Assignee: Toppan Printing Co., Ltd.Inventors: Naoshi Umetsu, Hayato Arai, Kunio Yamamoto, Shuzo Shiraki
