Description

50

The invention relates to a container for storing and mixing the individual components of Mixtures of substances, especially dental amalgams, with two chambers for one each Fabric are separated from one another by a partition that is joined together by external pressure formed with the substance contained in the first chamber in the second, the mixing of the substances Chamber can move.

In a known container of this type (German Patent 640 97 (5), the intermediate wall is formed by a piston with sealing washer, the piston rod extends over the entire length of the first chamber and by their end wall to the outside. When the piston with the sealing disk in the If the second chamber is to be moved, this is done by exerting the required pressure from the outside via the piston rod , thereby increasing the volume of the first chamber, so that a negative pressure initially arises in it, in addition to that between the sealing washer and the inner wall the first chamber as well as prevailing between the piston rod and the end wall of the first Kanuner friction must be overcome before the washer enters the second chamber. Once the Verbin connection between the two chambers prepared is. have the sealing washer and the piston performs its task and are then only a hindrance when mixing the two substances if it is not possible to pull the piston and the sealing washer with the piston rod back into the first chamber without some of the substance originally contained in the first chamber getting back there and the mixing ratio is thereby falsified.

It is also a container for storing and mixing the individual components of a mixture of substances known (USA.-Patent 2 527 992), in which two chambers for one substance each also through a Partition wall are separated from each other. The two chambers are partially nested by two Cups formed; the partition is on the inner face of the smaller diameter Beaker attached and has a hole which is closed with a spindle-shaped stopper. If the two cups are pushed further into one another, the cup, which is larger in diameter, also hits its bottom against the stopper and presses it through the hole in the partition wall into the second chamber, wherein the plug releases from the partition and then free in the second chamber is movable. However, the partition wall remains as a separating component between the two chambers obtain; the contents of the first chamber can only flow completely into the second chamber if the container is held exactly vertically, and when shaking the container it can hardly be avoided that part of the two substances flows back through the hole in the partition into the first chamber and the influence of the stopper, which is supposed to have a stirring effect when shaken is.

The invention is based on the object of providing a container of the type described at the outset to develop that the partition after connecting the two chambers the mixing process not disabled.

According to the invention, this object is achieved in that the partition itself is provided with a stirring body is formed, which is formed by reducing the volume of the first chamber from the container wall can solve between the two chambers and is freely movable in the second chamber.

In a preferred embodiment of the subject matter of the invention, the first chamber is on the outside Completed by a piston, which is up to m the originally occupied by the agitator as a partition Can move position and there the second, the entire mixture of substances and the agitator receiving chamber closes again. The interior of the container is opened by moving the piston limited to the area of the second chamber, so that nothing when shaking the container can get back from the container contents into the first chamber and the stirring body when shaken

The in F i g. The container shown in FIGS. 1 to 3 consists of 45 agitator bodies 39 in FIG. 2 as seen from a sleeve-shaped upper container part 10, arranged in the annular groove forming a seat. In the cup-shaped lower container part 20 and in this case, the substance A in the lower container part is fitted to a piston 30 which is inserted into the open upper end of the 20, the container parts 10 and 20 become the upper container part 10. The two containers are combined with one another, and then the protruding parts 10 and 20 are shown according to FIG. 2 and 3 carried out with a tightly nested, yet necessary work fit, sealingly pushed into one another,
cut open 12 and 22. When substances A and ß are to be mixed.

In the idle state of the container, which is shown in FIG. 2, a pressure is exerted on the piston 30, and is so positioned, the upper container part 10 forms a first direct or indirect compressive force on the agitation chamber 14, while the lower container part 20 has a body 39 applied, the hydrostatic second chamber 24 forms. Between the two pressures of the chambers 14 and 24 contained in the first chamber 14, a spherical material / f plays a certain role as a partition, so that the agitator agitator 39 is held in a frictionally engaged manner; to body 39, and with it the substance B, in the second for this purpose the upper container part 10 has a to chamber 24 falls. When the piston 30 continues after the agitator 39 matching ring groove. The 60 is pressed down, it finally assumes the position shown in piston 30 by inwardly protruding projections in FIG. 3. in which the second chamber or an annular bead 18 at the free end of the upper 24 is now hermetically sealed again.

The in F i g. 4 to 6 on the one hand and in F i g. 7 and 8, on the other hand, also have variants shown each an upper container part 40, a lower container part 50, a piston 60 and one as a partition between two chambers 44 and 54 serving, held in an annular groove 46 of the upper container part 40 spherical agitator body 69. The container parts 40 and 50 have according to FIG. 4 and 5 interlocking End sections 42 and 52 at the top of the upper container part 40 is a set of Projections 48 are provided. The piston 60 is similar in shape to the piston 30 in FIG. 1 to 3; he consists of an upper portion 62 and a piston head 64 with a concave lower end face 66

The diameter of the spherical stirring body 69 is slightly larger than the inner diameter of the upper Chamber 44, so that the stirring body with a slight deformation of the inner wall of the upper container part 40 is held positively and frictionally in its position.

On the upper container part 40, according to FIG. 7 and 8, instead of the annular groove 46, two ribs 46 α and 46 ft are provided; these ribs flank or enclose the equator of the spherical stirring body 69.

In the exemplary embodiments described, the piston 30 or 60 is essentially cylindrical; however, it can also have any other shape that corresponds to the inner shape of the upper container part 10 or 40 fits, so that there is a sliding seat with a perfect seal.
