Abstract: A capsule for mixing and dispensing a dental material which has a capsule body and a cavity extending into the capsule body. The cavity is closed by a liquid container. The liquid container has a cartridge forming a channel that extends between a front opening and a rear opening of the cartridge. Further the cartridge has a front foil closing the front opening and a rear foil closing the rear opening. The front foil is attached at the cartridge along a closed path circumferentially around the front opening. The front foil and the cartridge in at least a partial area of the circumferential path are separably sealed with each other, thus defining an openable valve through that path. The capsule has further a piston received in the channel of the cartridge and arranged such that the liquid is enclosed in the cartridge between the front foil and the piston. The capsule facilitates the preparation of a two-component dental material.

Abstract translation: 一种用于混合和分配牙科材料的胶囊，其具有胶囊主体和延伸到胶囊主体中的空腔。 空腔由液体容器封闭。 液体容器具有形成在筒的前开口和后开口之间延伸的通道的盒。 此外，盒具有封闭前开口的前箔和封闭后开口的后箔。 前箔沿着围绕前开口周向的封闭路径连接在墨盒上。 在圆周路径的至少一部分区域中的前箔和盒可彼此分离地密封，从而通过该路径限定可打开的阀。 胶囊还具有容纳在药筒的通道中的活塞，并且布置成使得液体被包封在前箔和活塞之间的药筒中。 胶囊有助于制备双组分牙科材料。
