Definitions

  • ABSTRACT A compounding vessel for component substances which interact and form ready-for-use dental preparations.
  • the vessel has a main chamber forming a mixing compartment (and adapted to contain a first component), and a supplementary chamber (adapted to contain a second component) separated by a membraneclosed opening from the mixing compartment. Mixing is effected by rupturing the membrane by pressure applied in a direction towards a wall of the main chamber.
  • the invention relates to a compounding vessel for component substances which interact and form readyfor-use dental preparation, comprising a main chamber forming a mixing compartment and adapted to contain a first component, and at least one supplementary chamber adapted to contain respectively, one or more additional components and which adjoins a portion of the outside wall containing an opening which communicates with the mixing compartment, and which is closed by a membrane or bag which is ruptured when for the purpose of combining the components the capacity of the supplementary chamber is reduced.
  • German patent application No. 1,939,316 describes a mixer vessel in which the supplementary chamber, which again contains a foil bag, is disposed between a piston that can be moved inside the main chamber and a plunger which is movable in relation to the piston.
  • the reduction in capacity of the supplementary chamber for the destruction of the foil bag and the discharge of its contents into the mixing compartment of the main chamber is effected by displacing the plunger in relation to the piston.
  • the piston is displaced in the cylindrical main chamber and expels the mixture through a delivery nozzle in the other end wall of the main chamber.
  • the present invention seeks to provide a compounding vessel for the production of dental preparation, which on the one hand enables the desired preparation to be produced in precisely the required mixture proportions without any risk of the inclusion of foreign matter and, on the other hand, comprises simple, easily produced elements that can be assembled without much trouble.
  • the capacity of the supplementary chamber is reduced by pressure applied in a radially inwards direction towards the wall of the main chamber.
  • a pressure can be generated by a thrust-induced movement, which can be abruptly produced, causing the capacity of the supplementary chamber to be reduced essentially to zero and thus completely discharging the component of the mixture in the bag.
  • the opening in the cylindrical wall of the main chamber may be so disposed that a plunger, which may be provided in the main chamber, can be displaced to cover said opening after the supplementary chamber has been emptied and before the mixture is shaken, so that on the one hand portions of the ruptured bag cannot enter the mixing compartment and, on the other hand, the mixture cannot leak back into the possibly re-expanded supplementary chamber.
  • a plunger can be designed to move easily since it does not require the cooperation of arresting means and need not overcome special frictional resistance.
  • Another advantage of the invention is that a compounding vessel based on the proposed principle of construction can be readily designed to mix three or more components by the provision of additional supplementary chambers.
  • the supplementary chamber is constituted by a movable wall such as a partially cylindrical clip containing the second component in a foil bag, the internal diameter of said clip being substantially equal to the external diameter of a cylindrical wall of the main chamber and being held by engageable retaining elements in a position in which the inner surface of the clip is spaced away from the external surface of the cylindrical wall by a distance equal to the thickness of the filled .foil bag.
  • the compounding vessel in this arrangement is easy and cheap to produce and no strict tolerances need be observed.
  • two foil bags may be located either under a common, axially wider, clip, or one under each of two different separate clips.
  • the supplement chamber is constituted by a cylindrical attachment disposed with its axis normal to the axis of a cylindrical main chamber and containing an axially slidably movable plunger which closes its free open end.
  • this latter embodiment can be provided with an additional supplementary chamber which may resemble or be identical with the first supplementary chamber, and which is likewise attached to the main chamber, both supplementary chambers being preferably coaxially disposed.
  • one end of the main chamber is closed by an axially tapering end wall from the centre of which an ejector nozzle projects, whereas the other end is closed by an axially slidably movable plunger.
  • a mixer vessel which is thus constructed permits a ready-mixed dental preparation to be directly injected into the dental cavity that is to be filled.
  • FIG. 1 is a first embodiment of a compounding vessel according to the invention, in longitudinal section,
  • FIG. 2 is a cross section taken on the line II II in FIG. 1,
  • FIG. 3 is a second embodiment of a compounding vessel according to the invention, likewise in longitudinal section, and, I
  • FIG. 4 is a cross section taken on the line IV IV in FIG. 3,
  • FIG. 5 is an additional embodiment of the present invention in longitudinal section.
  • this comprises a generally cylindrical main chamber of a circular cross-section, containing a first substance (not shown) which may be in the form of a powder.
  • the lower end of the cylindrical main chamber 10 is terminated by a hemispherically domeshaped portion 11 which is formed with a delivery nozzle l2 projecting therefrom coaxially with the longitudinal axis of the main chamber 10.
  • the mouth of the nozzle 12 is closed by a removable pin 13.
  • the upper end of the main chamber 10 is closed by a hollow plunger 14 which has a hemispherically dome head facing the interior of the main chamber, the radius of this dome head being equal to the radius of the interior of the dome-shaped portion 11.
  • the cylinder wall of the main chamber 10 is formed externally with two annular flanges 15 provided with axially aligned gaps 16. These two annular flanges 15 serve for axially locating a roughly semicylindrical clip 17 which embraces the outside of the cylindrical wall of the main chamber 10.
  • ribs 18 are formed between the two annular flanges 15. These ribs 18 are adapted to engage notches 19 or 20 formed on the inwardly facing surfaces of the ends of the clips 17.
  • the clip 17 is provided with a bulbous enlargement 21 which extends in the axial direction, the length of this enlargement exceeding the distance between the two annular flanges 15, its ends aligning with the gaps 16 in the annular flanges.
  • the cylindrical wall of the main chamber 10 contains an opening 22 facing the clip 17.
  • a bag 23 of rupturable material e.g., metal foil
  • the bag walls are of material of two different strengths, that facing the opening 22 being weaker than the other.
  • one component of the substance to be mixed is placed in the chamber 10 and the other component is in the bag 23.
  • the clip 17 is forced from the position shown in FIGS. 1 and 2 (in which the ribs 18 engage in outer notches 19) inwards towards the wall of the main chamber 10 until the ribs 18 snap into engagement with the inner notches 20.
  • the wall of the bag 23 facing the opening 22 will burst and the substance contained in the bag will spill through the opening 22 into the mixing compartment of the main chamber 10.
  • the ribs 18 which engage the notches 20 prevent the clip 17 after pressure on the clip is released from being forced back by the resiliency of the clip and possibly drawing some of the mixture, by suction outwardly through the opening 22. Since the radius of the inner wall of the clip 17 in the region holding the bag 23 is equal to the radius of the external surface of the cylindrical wall of the main chamber 10, the bag 23 is pressed completely flat and is substantially completely empty when the ribs 18 snap into engagement with the inner notches 20.
  • the vessel can then be shaken (e.g., in a mechanical shaker) for thoroughly mixing the two combined substances.
  • the pin 13 can be pulled out of the nozzle 12 and the ready-mixed dental preparation introduced directly into a cavity of a tooth by expelling the compound through the nozzle 12 by means of the plunger 14.
  • the displacement of the plunger 14 inside the cylindrical main chamber 10 may possibly be effected by auxiliary means.
  • the fact that the internal wall of the portion 11 of the vessel and the facing surface of the head of the plunger 14 are parts of spheres having identical radii, substantially all the compounded preparation in the chamber 10 can in practice be ejected.
  • the main vessel 10 is formed in the same way as in the previously described embodiment with a part spherically domed portion 11 which is centrally elongated into a delivery nozzle 12 which is closed by a removable pin 13.
  • the hollow plunger 14' in this embodiment is extended rearwards beyond the end of the main chamber 10 and its rear end is formed with a flange 30.
  • the rear end of the main chamber 10 is likewise formed with a flange 31.
  • the internal wall of the main chamber 10 is again of circular cylindrical shape, whereas its external wall has a central portion which is square in cross section, as can be seen in FIG. 4.
  • each accessory chamber 32, 33 is closed by a destructible membrane 37 (e.g., of foil) which also seals the corresponding holes 34 and 35 into the main chamber 10.
  • the other end of each accessory chamber is closed by a slidably movable hollow plunger 38 which differs from plunger 14 in nothaving a hemispherical, but a flat inner face 39.
  • the ac'cessorychamber 32, 33 may be affixed to the square 'side'fac'es ofthemain chamber either with an adhesive, or the'y may'be fused or secured in some other convenient way.
  • Flanges 41 provided on the accessory chambers may be arranged to engage rails 42 formed on the outside square faces of themain chamber 10.
  • the compounding vessel illustrated in-FIGSJ3 and 4 is used by first emptying the two accessory chambers 32 and 33 by pushing their plungers38'inwards, (possibly in a prescribed order consecutively). If both chambers are emptied simultaneously pressure can be applied to the terminal flanges 40 from both sides; if each chamber is to be emptied separately, this can'be-done manually by applying the thumb to one of the flanges, say 40, and the index andsecond' fingers to the other flange 36. Inward displacement of the 'plunger 38 causes the membrane 37 to bedest'royed and the substance in the chamber, say a liquid, to be forced through the appropriate hole 34 or 35 into the mixing compartment of the main chamber 10.
  • the pin 13 is removed from the nozzle 12 and the finished dental preparation can be ejected possibly'di'rectly into a dental cavity by pressing the plunger l4"inwards.
  • the plunger 14 in the embodiment according to FIGS. 1 and 2 may be rearwardly extended like the plunger 14 and both plunger and main chamber may be provided with terminal flanges.
  • the compounding vessel according to FIGS. 3 and 4 may be fitted with only one accessory chamber.
  • the vessel according to FIGS. 1 and 2 may be provided with two openings 22 and two bags 23 may be located either under a wider clip or under two separate clips. When two separate clips are provided the two bags can be emptied in succession.
  • a single membrane 37 one or both the accessory chambers 32, 33 in the embodiment according to FIGS.
  • FIG. 5 illustrates the embodiment of the present invention in which more than one opening is provided under a single clip.
  • openings 22 and 24 correspond respectively to bags 23 and 25.
  • the bags are positioned over their respective openings, thereby permitting separate components to be added to main chamber 10 without premixing.
  • the membranes or bags of the present invention can be of any suitable material which has the characteristics of being compatable with the components to be mixed, and which is easily rupturable upon application of external pressure.
  • the material could be metal foil, treated paper, cellophane and other materials within the pen of a skilled artisan.
