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.

Abstract translation: 提供一种双组分混合容器，其中活塞构件可以能够进行旋转运动操作和线性运动操作，而不需要复杂的引导槽。 在活塞构件上设置有两个或更多个弹簧结构部分。 两个或更多个弹簧结构部分在第三圆柱形部分的内壁表面上施加按压力。 在第三圆筒部形成有两个以上的配合槽。 在该装配状态下，活塞部件和第二部件容纳部件一起转动，而没有接触部分脱离配合槽。 当具有第二部件容纳室和混合室彼此连通的向第三底壁部分施加预定水平或更高的力被施加到操作杆部分时，接触部分从配合槽中脱出。

Abstract: Provided is a two-component mixing container in which a communication passage may be formed between a partition wall member and a second-component containing member without the need for a high processing precision and a high assembly precision. A columnar portion provided at the central portion of a second bottom wall portion of a partition wall member and a circular through hole provided in the central portion of a third bottom wall portion of a second-component containing member are fitted. A first communication passage and a second communication passage are communicated with each other, using a fitting surface formed between the columnar portion and the circular through hole.
