Abstract: A paste-type dental material is filled from an opening portion of a cartridge into a cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge along a kneading surface, on which the paste-type dental material is kneaded, with the opening portion being inclined. The piston is placed on the kneading surface with a circular end surface of the piston contacting the kneading surface. The piston is inserted into the cylindrical portion by moving the opening portion of the cylindrical portion of the cartridge closer to the piston located on the kneading surface such that a piston-side tapered surface or the piston-side curved surface of the piston is fitted into the opening portion, and thereafter moving the one of the two ends of the cylindrical portion toward the kneading surface.

Abstract: An applicator that is less expensive than those according to the related art and in which a plunger does not easily slip out of a cylindrical syringe. A cylindrical syringe and a plunger are each molded from a resin material. A resistance structure is provided between the inner peripheral surface of the cylindrical syringe and the outer peripheral surface of a pressing portion of the plunger. The resistance structure is configured to act as resistance to movement of the pressing portion when the pressing portion is moved toward a cartridge fitting portion beyond a predetermined position and to movement of the pressing portion when the pressing portion is moved from the side of the cartridge fitting portion toward an end of the cylindrical syringe opposite to the cartridge fitting portion beyond the predetermined position.

Abstract: Provided herein is a viscous material container that is not likely to form continuous streaks or asperities on the surface of a viscous material discharged from the viscous material container even if the viscous material is highly viscous. A third section of a housing includes a wall having a wall portion that is positioned radially outwardly of a continuous angular portion with respect to a second imaginary center line, and extends along the continuous angular portion. The wall portion is configured to expand radially outward when a dental viscous material pushed out from a discharge port.

Abstract: Provided is a two-component mixing container in which a piston member may be capable of a rotation motion operation and a linear motion operation without the need for a complex guide groove. Two or more spring structure portions are provided at the piston member. The two or more spring structure portions impart a pressing force on an inner wall surface of the third cylindrical portion. Two or more fitting grooves are formed in the third cylindrical portion. In this fitting state, the piston member and a second-component containing member rotate together without contact portions getting out of the fitting grooves. When a force of a predetermined level or higher toward a third bottom wall portion is applied to an operating rod portion with a second-component containing chamber and a mixing chamber being communicable with each other, the contact portions get out of the fitting grooves.
