Definitions
- the invention concerns a mixing and application or dispensing capsule for dental mate ⁇ als.
- a tubular piston is supported against the container with a tear-off ⁇ ng.
- the tear-off ⁇ ng is removed with a g ⁇ pper tool.
- a container has in one end lying opposite a throughput borehole a correspondingly configured projection, which engages in a correspondingly configured recess of the tubular piston in the resting state, and secondly by the fact the container has, above the throughput borehole, a guide groove, in which a slider joined with a discharge cannula is guided m a sliding motion and can be stopped both in the sealing and conducting positions.
- the tubular piston can be displaced without friction up to a limited feed or advance.
- the blocking function which is produced by the interaction between the projection of the inside wall of the container and the recess of the outer wall of the tubular piston is joined at a limited extent of advance of the stamp, which is sufficient for emptying the tubular piston, while it terminates after this.
- the friction-free advance after mixing can only be guaranteed if the projection lies on the inner wall of the container and the recess lies on the outer wall of the tubular piston
- the radial projection of the container which is shaped as a convexly arched inner surface, engages in the radial recess of the tubular piston, which is shaped as a concavely arched outer surface.
- the stamp is shaped like a cylinder with a uniform outer diameter, which is adapted to the diameter of the tubular piston The diameter is reduced only m the short region of the stamping plate.
- the guide of the stamp in the piston is stable such that even with an oblique placement of the piston for activating the mixing and dispensing capsule, no radial gap is formed between the inner wall of the tubular piston and the outer wall of the stamp, and thus a leaking out of liquid is reliably avoided.
- An erroneous pressing of the stamp is avoided in that the friction between the stamp and the tubular piston is selected sufficiently high.
- This can be accomplished, on the one hand, by an approp ⁇ ate adaptation and mate ⁇ al selection for the stamp and the tubular piston and or, on the other hand, by an approp ⁇ ate catch or snap connection as desc ⁇ bed above between the stamp and the tubular piston.
- this can be accomplished by an elastic O- ⁇ ng which may be located in a recess in the stamp wall. Another advantage of the elastic O- ⁇ ng is the increased sealing between the inner wall of the tubular piston and the outer wall of the stamp.
- the liquid container which is formed by the tubular piston, the stamp as the bottom and the foil as the cover, can be mounted and filled in a simple way. Since the mixing and dispensing capsule will hold different dental mate ⁇ als, it is understood that the mside space of the tubular piston that is not taken up by the stamp, as well as the mside space of the container not taken up by the tubular piston, will have sufficient remaining space m order to take up the quantities of the mixing components that occur, whereby the residual volume in the container must be designed for liquid components and for the mixing process, in addition to holding the powder components.
- the container has, above the throughput borehole, a guide groove that becomes wider toward the mside, in which a conical slider, which is joined with a discharge cannula without a transition, is held m a sliding manner.
- An accidental displacement of the slider will be avoided by the cooperation of an approp ⁇ ately configured bucklmg-out piece on the underside of the slider and two approp ⁇ ately configured indentations in the guide groove of the container.
- the resulting friction between the slider and the guide groove is selected in such a way that the slider can be actuated by hand.
- the slider seals the mixing and dispensing capsule m an air-tight manner, by catching the bucklmg-out piece of the slider in the indentation of the guide groove lying closest to the discharge opening After mixing, the slider is displaced in the direction of the indentation lying further away to the throughput borehole and after a specific amount of displacement catches with its bucklmg-out piece on the underside.
- Fig. 4 shows a longitudinal section of the slider and the guide groove in a single representation.
- Fig. 5 shows a section along line A-A of Fig. 4.
- Fig. 6 shows an alternative embodiment of the capsule of Fig. 1.
- Channel 35 between discharge opening 32 and mouth opening 36 is constricted in a funnel form in the region of the inner wall of slider 32 and runs slightly conical in the region of the inner wall of discharge cannula 30.
- a particularly favorable flow profile results, which facilitates the discharge of highly viscous dental mate ⁇ als, such as, for example, glass lonomer filling cements.
- discharge cannula 30 is bent in such a way that a favorable working range of 30-50° relative to the longitudinal axis of the mixing and dispensing capsule results thereby.
- the cyhnd ⁇ cal inner wall 19 of container 10 forms a well-sealing guide for tubular piston 20, which serves on the one hand as a liquid container and on the other hand as an uptake for stamp 40.
- container 10 has an outer projection m the form of an annular groove 17, which produces the connection with a discharge g ⁇ pper tool (not shown) acting on stamping surface 43.
- Inner wall 19 of container 10 ends m a radial, convexly arched inner projection 18, which has a smaller diameter than the mside wall 19 of the container. Projection 18 is limited at the bottom by the radial foot surface 7.
- the mixing and dispensing capsule can be emptied. This is done by inserting the mixing and dispensing capsule into a known discharge g ⁇ pper tool. The finished mixture is pressed out through discharge cannula 30 by advance of stamp 40, whereby the empty state is shown in Fig. 3. Tubular piston 20 is then completely pushed into mixing chamber 8 with the pushed-m stamp 40.
