can; to make this possible, the container comprises a pressure piece which is slidably mounted in the end of the container facing away from the other chamber

One of the chambers can accommodate the partition or the ball, which acts practically in the manner of a mortar punch, around the two substances contained in the chambers to mix intimately with each other.

The chamber into which the partition is pressed, can be separated by two components that are pushed into one another and fastened to one another or connected by a threaded connection

The pressure piece is preferably through the shaft of a Piston formed, which can move along the wall of the chamber in which it is slidably mounted to this one To pass opening that has a diameter that differs only slightly from the diameter of the chamber, so that the pressure piece due to the elasticity of its material or the elasticity of the material surrounding the pressure piece simple application of a compressive force can be built in »

According to an important feature of the invention, there is a Such a container of two separable and interconnectable sections, each of which is one Delimits chamber for receiving a certain material. One Partition, which preferably has the shape of a ball, is in the two sections between a starting ^ - or closed position, in which it is frictionally in the upper part of the Container is detachably held, and a so-called ■ mixing

lower container part 20 and a pressure piece 30, which according to 2 and 3 in the open upper end of the upper container part 10 can be inserted. The two container parts can be pushed into one another with a sealing effect; for this purpose the container parts have socket-like end portions 12 and 22 which are closely fitted work together to make the two container parts 10 and 20 to stick together. .

The upper chamber 14- is formed in the upper container part, while according to FIG. 2 the lower chamber 24 is formed in the lower container part 20. Between the two chambers, a partition wall may spherical _o a valve member are held frictionally or 39; for this purpose, for example, the upper container part 10 is provided with an annular groove that matches the ball 39. Inwardly protruding projections 18 or a gapless bead serve or serve to hold the pressure piece 30 in the free end of the upper container part 10.

The container parts 10 and 20 can, according to FIG. 1, preferably with outer ribs or reinforcing sections 19 or 29 be provided to increase the rigidity of the container in particular to enlarge in the area of the lower chamber 24. It should be noted that such reinforcing ribs are shown only in the first embodiment, because when the container parts get a sufficient wall thickness, it is not necessary to provide such reinforcing ribs.

The pressure member 30 includes an upper portion 32 which can be actuated by hand, and a lower portion 34 of FIG. 1 can form a head of larger diameter _o preferably, but not necessarily, the lower end face of the pressure member 30 may be in the at 36 is given a concave shape so that it fits the shape of the partition 39 formed by a ball and closes the lower chamber 24 when the pressure piece according to FIG. 3 has been pushed or pressed completely into the upper container part 10. In order to facilitate manufacture and to save material, the pressure piece 30 can be provided with an axial opening 38 at its upper end, but this measure does not noticeably change the mode of operation of the container.

In order to fill the container or the device according to FIGS. 1 to 3, one can proceed in the manner described below. Here-one starts from the assembled container, doh. of the container parts 10 and 20 according to the drawing are connected by an interference fit or by a threaded connection (not shown). The ball 39 and the pressure piece are not yet installed, so that the two chambers 14 and 24 with the outside of the container via the channel or the Opening of the upper container part 10 below the bead or the projections 18 are in connection.

It is poured into the lower chamber 24, i.e. the lower part of the container 20, insert the desired amount of the first material marked A · Then insert the ball 39 by adding you can e.g. "with the help of a mandrel, a rod or a

209810 / 0SB2

a similar tool of a known type into the ". Chamber 14 - presses. Because of the elasticity of the material of the ball or of the container part concerned, the ball 39 moves first past the bead 18 down to then from the annular groove to be received at the lower end of the upper chamber 14 «, The ball now forms a leak-proof partition between the two chambers 14 and 24.

Now, it is poured into the upper chamber 14, whose upper end is still open, the desired amount of the second material Bjnunmehr it is only required 30 so passing out the Druckstüek to the bead 18 that the position shown in I ¹ Ig ₀ 2 occupies. The container filled in this way is now ready to be stored or transported. It should be noted that the operations described are carried out without it being necessary to separate the container parts 10 and 20 from one another, because only the opening or the Kqnal from the upper chamber 14 to the outside is used to fill the container of the container leads.

Of course, it is also possible to use the container parts 10 and 20 to. Filling to separate from each other if one previously did the Ball 39 in the manner shown in FIG Arranges the seat forming hanging groove. In this case the material A is introduced into the lower container part 20, the container parts 10 and 20 are united together, and then become the operations described above are carried out.

209Ö10 / 05E2 bad

When the materials or the mixture formed from them are removed from the container after storage or transport is to be, it is sufficient to exert a pressure on the pressure piece 30 in order to directly or indirectly apply a pressure force to apply the ball 39 so that the ball falls into the lower chamber 24. It should be noted that here the hydrostatic Pressure of the material B contained in the upper chamber 14 plays a certain role.

The partition, which was previously formed by the ball 39 and separated the two chambers from one another, is thus practically eliminated so that material B can fall to mix with material A in lower chamber 24,

If the pressure piece 30 is printed further back, it finally assumes the position shown in FIG the base portion with the lower end face 36 on the mentioned annular groove, so that the chamber 24 is now hermetically sealed again.

• You can now shake the container vigorously in order to mix materials A and B thoroughly. As already mentioned, can the material A is a metal powder and the material B is mercury, so that the mixing process an amalgam arises, e.g. for dental purposes is suitable »The mass of the ball 39 contributes effectively to the thorough mixing of the two materials.

After shaking the container for mixing of the materials can, the container parts 10 and 20 separated from each other, so that the mixture or the amalgam, which is now in the ge "

opened lower chamber 24 of the container part 20 is contained, can easily be removed _o

Another preferred embodiment of a container ^{according to the invention is shown in B 1} Ig ₀ 4 to 6, while FIGS. 7 and 8 usually show a further variant in a partial illustration. It should be noted that the modifications shown can also be provided in the first embodiment, μηά that certain features as desired in the two slightly differing embodiments may be provided _e In the figures, the descriptions of like or similar parts concerted

The upper part of the tank, the lower part of the tank, the The pressure piece and the ball forming the partition are marked with 40 or 50 or 60 or «69, while in FIGS. 1 to 3 the corresponding reference numerals 10, 20, 30 and 39 are used are. The container parts 40 and 50 have socket-like end sections 42 and 52, and the two chambers are designated 44 and 54, respectively. In Fig. 4 one recognizes an annular groove 46, which corresponds to the ring groove indicated in FIGS. 2 and 3; how previously there is a bead at the upper end of the upper container part 40 48 or a set of protrusions is provided.

This embodiment is not with reinforcing ribs provided, but it should be noted that one can also use the information given in Fig. up to 3 could provide the shape described

The pressure piece 60 has a similar shape to the pressure piece 30, i.e. it comprises an upper portion 62, a lower portion 64 and a concave lower face 66;

209 810/0552

for simplification, the concave lower end face can of course also be omitted.

The mode of operation of the second exemplary embodiment corresponds to that of the exemplary embodiment described first, so that a repetition of the description should be superfluous. When the container is shown in FIG Has been filled, the ball 69 separates the chambers 44 and 54 from each other. The diameter of the ball 69 is chosen so that the ball fits into the annular groove or constriction 46. In this case, too, the ball is used when mixing the both materials A and B in the lower chamber 54 (see Figo 5) as a mortar pestle. The annular groove 46 is preferably open arranged at the same height as the junction between the two chambers 44 and 54.

The diameter of the ball 69 is chosen so that it is slightly larger than the inner diameter of the upper chamber 44, so that the ball with a slight deformation of the inner wall of the upper container part 40 frictionally in place is held

In FIG. 6, projections can be seen at 48a which are provided in a somewhat differently shaped upper container part 40a which cooperates with a correspondingly modified pressure piece 60a and is mounted displaceably between the projections. The lower extension of the upper container part 40a is in iig. 5 denoted by 42a, while the annular groove is indicated at 46a. The pressure piece 60a includes an upper portion 62a _t a lower portion 64a and a lower end surface 66a,

209810/0552

The construction according to Fig. 5 and 6, otherwise corresponds largely to that described with reference to Figure "4 ₀

It is also possible according to FIG. 7, with a modified one Embodiment of the upper container part 40b to provide two ribs, as shown in Fig. 7 at 46b and 46b ' These ribs flank or enclose the equator of the sphere. 69 · / · "

Pig, 8 shows a further modified embodiment, in which the pressure piece 60c has a substantially cylindrical upper section 62c and a slightly at its lower end thickened head portion 64c comprises, just above the Head portions an annular bead is provided. the lower face of the pressure piece is concave. The upper container part, designated 40c, has one or two inwards protruding rib-like projections 46c and 46c 'which flank the outwardly bulging head portion 64c. In this modified construction, the pressure piece 60e not be pushed deeper into the lower chamber 54, than the annular bead allows, so that the lower chamber is closed.

In the exemplary embodiments described, the pressure piece essentially has a cylindrical shape. It should be noted, however, that it may also be any other form of the pressure member leading to the interior shape of the channel of the upper container part fits, when it is possible to see _t vorzuw a sliding fit and to ensure that the pressure element causes a perfect seal when it is completely inside

The container parts "do not need to be cylindrical either, however, cylindrical container parts can be produced most easily, especially if they are made of a plastic exist «However, one could also use a rectangular, an octagonal or any other container according to the invention Provide a different cross-sectional shape.

It should be noted that the diameter of the circle ^{which can be struck between the projections 48 according to S 1} Ig ₀ 4 and the projections 48a according to FIGS The difference in both cases is sufficiently small that the pressure piece, because of the elasticity of the walls of the container part, can be inserted in a simple manner by inserting the pressure piece into the free opening of the upper container part 40 or 40a with the use of force.

The concave lower end face in Figs. 3 to 5 as well α in Fig »8 shown pressure pieces prevents the sticking of the mixed materials while shaking the container, since there are no corners or edges between the adjacent parts Column are present.

It should be noted that various changes and modifications can be made in the above-described embodiments can provide without departing from the scope of the invention.
