A dental container (10) comprising means for containing liquid and solid powder dental materials initially in separated condition. The liquid is contained in a receptacle (22) having an inner wall (26) with a relatively thin weakened section (28). A plunger (30) is mounted in an open outer end (24) of the receptacle (22) initially. The receptacle (22) is inserted at a proximal end of an outer central body (12) whilst a separable nose portion (18) is mounted at a distal end of the outer central body (12). In use, the plunger 30 is used to rupture the wall (26) by hydraulic pressure or by means of a sharp projection (52) to cause the liquid to contact powder material held in a distal end of the outer central body (12) and the nose (18) for mixing to form a dental paste. The nose (18) is subsequently manually detached from the outer central body (12) so that the dental paste can be accessed for use.
A dental container arranged to contain a liquid and a solid powder initially in separated condition comprising an outer central body having a proximal end and a distal end, a liquid receptacle having a closed inner end and an open outer end mounted at the proximal end of the outer central body and a separable nose portion mounted at the distal end of the outer body initially for mixing purposes but which is arranged to be manually separated from the remainder of the container after mixing, a plunger mounted in the open outer end of the liquid receptacle, the closed inner end of the liquid receptacle being formed by a wall having a weakened section, the distal end of the central body and the nose portion being arranged to contain solid powder material, the arrangement being such that depression of the plunger causes the wall of the liquid receptacle to be ruptured at the weakened section so that the liquid and the solid powder material are contacted for mixing together to form a dental paste.
