DE1939316C - Mixing container for holding substances that react with one another for the production of ready-to-use dental preparations - Google Patents

Description

From the German edition I 276 866 and 1 287 251, multi-chamber containers for the storage

take from substances that react with one another for the production of ready-to-use dental preparations known in which the individual chambers are separated from one another by easily destructible membranes and the parts for receiving the individual mixing components are arranged such that they can be displaced relative to one another are; Instead of the membrane, the lid chamber can be used to hold the container one of the components can be provided with a cushion-shaped or hose-shaped sub-space which

is formed from a closed, preferably welded foil bag. Between the The main space of the container and the foil pouch can be one with holes and possibly with points be provided against the foil pouch provided insert or partition.

In these containers, the partition wall or the film cushion are destroyed by the move against each other Behäiteiteile or caused to burst, thereby providing a connection between the individual substances.

In the improved embodiment of the container according to German Auslegeschrift 1 287 251, the foil cushion, which is preferably filled with a liquid such as phosphoric acid, can be pressed out practically quantitatively and its contents can be transferred to the main chamber, which is preferably filled with a powdery substance such as Zinc oxide, or a silicate cement, is injected.This embodiment has the advantage over the embodiment according to German Auslegeschrift 1 276 866 that no film residues can get into the mixture.

After the two substances have combined

The substances currently in the main chamber must be thoroughly mixed ; rfolcen This is preferably done by Jer mixing container clamped in the fork of an automatic vibratory mixer and through Rapidly successive oscillating movements an inniize mixing is achieved.

With these containers, however, the ready-to-use mixture is removed after mixing certain difficulties as the holder te-.B. with a spatula,

must be taken. .

From the French patent specification 1> 72 328 * .and amalgam mixing containers are also known, de have the shape of a bottle. The neck portion in which is i stem _5-d is located ;, mercury is above a durcn licwegli '.' Hcn stamp completed. The mercury Ls ₁ is separated from the mixing chamber, which contains the silver powder, by a partition that sits tightly in the neck part. When the punch is pressed into the neck part, the partition falls into the expanded mixing chamber, together with the mercury, and the partition acts as a mixing pestle during the mixing process. After mixing, the container is dismantled to remove the mixture, * 5 s whereby in principle the same difficulties can arise as with the first-mentioned containers and in addition the parts of the mixture hanging from the separation must be removed with relative laboriousness.

An amalgam mixing container that is similar in principle, in which only the stamp and the separation for the mercury are effectively equivalent Way are combined with each other is already m the German Patent 640 976 described. The 35 so mixing chamber is placed on the neck part The rubber cap is used to knead the mercury with the silver powder. To relax in the automatic ones used today These mixing bowls are not suitable for vibratory mixing devices. As with those described above The removal of the finished mixture is relatively cumbersome from mixing containers.

Finally, from US Pat. No. 3,370,754, mixing syringes for medicament oils are known. One substance is located in a hollow piston, which is closed off from the second chamber with the other substance by a pin. The pin does not guarantee complete sealing of the hollow piston. For example, if the contents of the chamber expand as a result of heating, the hollow piston is pushed upwards, which means that the pin no longer closes tightly .

In the case of the closure 10 of FIG. I. Below the insert, when the plunger 4 is pressed down, there is also 10 a small foil bag 6 ″. In one of the pistons 3 there is a certain amount of movement, since the pressure is exerted by the second liquid substance? Which is transferred to the gas space via the liquid 7.

In this case, the mixing container is correspondingly longer than the mixing container according to FIG. 10. The function of the closure IO is the same as in FIG. 10.

In the embodiment of Fig. 1.1 is the Separation between mixing chamber 1 and second chamber 2 as a sleeve 3 'with diluted, destructible Testicle 3 ″, which is arranged in a perforated insert 3.

Only when you get stronger after your mixing pushes the plunger 4, the insert 3 is gcschoLeii in the mixing chamber 1. The lock IO has the same function as the shutter 10 of Fig. I.

The embodiment according to FIG. 4 shows a upper part of the container similar to that of Fig. 13, but instead of the bead-like widening of the Insert 3 a retaining ring 9 is provided which rests on the upper edge of the mixing chamber 1 and which is removed when the insert 3 is to be pushed into the mixing chamber.

The lower part of the mixing chamber I is provided with a short nozzle-shaped extension 11, onto which a cannula 11 'can be screwed or otherwise fastened after the substances have been mixed. The ready-to-use dental preparation is pushed out through the extension II, which can be closed by a thinned base part 12 or by a pin prior to mixing, and can be brought directly into the tooth cavity via the cannula IV.

In the embodiment according to FIG. 15, the chamber 2 is liquid or pasty Substance 7 in the form of a sleeve 3, which is also called a movable one The piston is used, separated from the mixing chamber 1. The sleeve 3 fits exactly into the mixing chamber is used and has a central, circular opening that is penetrated by a composite film 3 "in

ίο Shape of a disc with the metal side up shows, is closed and welded to the base of the sleeve 3 on the plastic side. The sleeve 3 is closed at the top by a stamp 4 which is provided with a closure film 21. At hercm At the lower end 9, the sleeve 3 is widened like a bead or is provided with a sealing lip. the nozzle-shaped extension 11 corresponds to the nozzle-shaped one Extension 11 according to Fig. 4.

The individual designs for the upper

ao and lower parts of the mixing container can of course be combined with each other, e.g. B. Upper part according to Fig. I, 7, 10 or 12 with lower part according to Fig. 2, 4. 5, 11 or 14, upper part according to FIG. 4, 5, 6, 8, 9, 14 or 15 with lower part according to Fig. I or 7 etc.

To mix the substances, the mixing container is preferably placed in the fork of an automatic Vibratory mixer (frequency about 2500 to 10,000, preferably about 4000 to 7000 Vibrations per minute), resulting in a homogeneous mixture within a few seconds he follows. Dns V ^ rmisrhi-n of the contents of the chamber can also be done in a vacuum. For this purpose, the mixing container is placed in an evacuated outer capsule.

Is used as the material for the sleeve 3 'according to FIG or 14 glass is used, it is advisable to place a sieve plate on the opening 14 of the parts 3 or to attach the sieve plate below the opening to prevent broken glass from falling into the Mixing chamber 1 to prevent.

Instead of the single opening 14 shown in FIGS. I, 2, 3, 4 A 13, 14 and 15 dci parts 3 can several openings can also be provided. The openings can also be designed as sieve openings.
