Definitions
- the present invention relates to a mixing capsule and a device containing a mixing capsule, in particular a mixing device and / or an application device, and a method for using the mixing capsule, in particular for producing a dental material which preferably contains several components.
- Mixing capsules which are filled by the manufacturer with the components in separate chambers, are used to produce mixtures from two or more components. The components are connected by the user, for example by destroying a wall separating the chamber, and mixed with one another.
- mixing capsules are known for the production of dental materials, which are often mixed from a powdery and a liquid component, the mixing process usually taking place in a shaker.
- a mixing capsule is known from DE 36 35 574 A, which is intended for the production of jointing and sealing compounds.
- a secondary chamber present in the dispensing piston is delimited by a film on the side facing the main chamber of the capsule and on the opposite side by an auxiliary piston which is displaceably arranged in the dispensing piston.
- a mixing body is accommodated in the secondary chamber, which first serves to destroy the film by manual displacement of the auxiliary piston and then supports the mixing process.
- a gas cushion is provided in the mixing chamber to enable the volume reduction required to move the inner piston together with the ball.
- the mixing ball is initially in the main chamber.
- it is in the piston existing side chamber opposite the main chamber closed by a lid and on the back by a bellows.
- the lid is pushed away from the piston by manual pressure on the bellows so that the two chambers for activating the capsule are connected.
- a separate manual step is required to activate the capsule.
- a gas cushion is also required to enable the volume reduction required to loosen the lid.
- a first component is contained in a mixing chamber and a second, liquid component is contained in a film bag which is arranged in a secondary chamber separated from the mixing chamber by a displaceable wall element.
- a cylindrical mixing body present in the mixing chamber serves to move the wall element at the beginning of the mixing process and thereby compress the film bag, so that it bursts open and releases the liquid component through a liquid passage in the wall element.
- a difficulty with this device is to design the wall element, the foil bag and the capsule itself and to dimension them with such small tolerances that the wall element is held in its initial position in the storage and transport state of the capsule, but under the influence of the mixing body is moved so far and with such force that the foil bag bursts open. It should be borne in mind that emptying the plastic bag often only partially leads to undesired changes in the mixing ratio and thus to deterioration in the properties of the finished mixture. Another disadvantage is that this arrangement is only suitable for mixing, but not also for applying the paste.
- a comparable mixing capsule is described in patent application WO 00/30953.
- a disadvantage of this mixing capsule is that when the capsule is activated by the ball, a not inconsiderable noise development can occur.
- the action of force caused by the mixing body can lead to the separation of the separating film, which can lead to undesired contamination of the material to be mixed.
- a primary object of the present invention can be seen in providing an improved mixing capsule which avoids the aforementioned problems without impairing the desired mixing result.
- the object of the present invention can be seen in providing a device which allows multicomponent materials to be mixed and applied in a simple manner.
- the mixing capsule according to the invention has i.a. the following advantages:
- the movable body present in the mixing capsule serves on the one hand to activate the capsule while destroying the separating device, and on the other hand it supports the mixing process.
- the fact that the body can change its outer shape during mixing means that the noise level decreases continuously during the mixing process.
- the spreading of the mixed mass is not impaired by the mixing body, which has proven to be an advantage in particular when spreading highly viscous material.
- the risk is also reduced that the separating device is separated from the piston during the mixing process and the separated parts contaminate the mass to be mixed or impair the application process.
- Changing the outer shape in the sense of the invention means plastic deformation, surface enlargement, destruction of the outer shape, pulverization of the material of the body, incorporation and / or incorporation of the material which the body comprises or of which the body consists essentially into the mixing substance. Since the body is in the main chamber in the initial state, the activation preferably takes place automatically at the beginning of the mixing process, in contrast to the activations to be carried out manually, which are known from the prior art.
- the secondary chamber is separated from the main chamber by the separating device which can be penetrated by the body, it forms part of the mixing chamber itself during the subsequent mixing process. This ensures that the second component contained in the secondary chamber is completely incorporated into the resulting mixture.
- the small number and simple design of the components of the mixing capsule are also advantageous.
- the movable body is preferably spherical.
- the diameter of the ball is preferably in the range from 4 to 10 mm, particularly preferably in Range from 5 to 8 mm.
- any other design of the body is also conceivable, for example a design in the form of an ellipsoid of revolution or a design with corners and edges, possibly in the form of a cube. Such a design can possibly destroy the separating layer more easily and possibly allows a smaller mass and / or size of the body.
- Usable spherical materials have a density in the range from 1.5 to 9.0 g / cm 3 , preferably in the range from 2.0 to 6.0 g / cm 3 .
- the mass of the body is usually in the range from 0.1 to 2.0 g, preferably in the range from 0.2 to 1.0 g.
- Materials which do not negatively influence the properties of the mixed mass are particularly suitable for the body in the mixing capsule.
- Such materials are preferably inorganic in nature, possibly ceramic in nature and include, for example, glass, silicon oxide, aluminum oxide or zirconium oxide.
- Contamination of the mixed mass by material from which the body is made can also be avoided by the body being made of the same material, possibly including this, which may be the first component in powder and / or granule form in the main chamber of the capsule located.
- the body is preferably produced from the material of the first component via a pressing process.
- this embodiment enables the size of the mixing capsule to be reduced, since during the mixing process the dissolving body becomes part of the material to be mixed and thus does not restrict the volume required for the mixing process.
- the shape of the secondary chamber may have the shape of a hemisphere with a slightly larger radius than the body.
- any other design is also conceivable, for example a cylindrical shape.
- the total volume of the mixing capsule available for mixing is usually in the range from 0.5 to 5 ml, in particular 1 to 3 ml.
- the volume of the secondary chamber is preferably less than the volume of the main chamber.
- the volume of the secondary chamber is usually 0.05 to 0.5 ml, preferably 0.1 to 0.3 ml.
- the mixing capsule according to the invention also does not necessarily require the presence of channel-shaped depressions, which can be incorporated, for example, in the secondary chamber in the form of grooves and / or in the end wall of the main chamber in the form of channels, in order to ensure that particularly viscous substances are dispensed from the mixing capsule ,
- the separating device has at least one predetermined breaking point which, regardless of the nature of the edge region of the piston at the transition to the secondary chamber, contributes to a targeted and safe opening of the secondary chamber.
- the pre-damage to the separating device or the preparation of a predetermined breaking point can take place, for example, by radiation, such as laser radiation, mechanically by scratching or cutting with a knife, or thermally by melting or scratching with a heatable knife.
- the preparation is preferably carried out only on the plastic part of the separating device, if any, i.e. on the one or both
- the shape of the preparation is arbitrary, but is preferably carried out in a form which avoids tearing off the separating device or parts thereof after or when the separating device breaks through the body. Preparing the separating device in the form of two or more lines crossing each other in the axis of symmetry of the capsule has proven to be advantageous.
- a star-shaped preparation with branching branches can also be used. Such a preparation simplifies the mixing process, since wedge-shaped film parts of the separating device have a shorter chord length in the area of the wall of the secondary chamber, as a result of which the film components can be folded over more easily during mixing.
- a preparation is also favorable in which a film part has the outlines of a bowling cone, the cone head being circular and the center of which is located on the longitudinal axis of the cartridge. This preparation also facilitates the largely complete opening of the separating device and thus access to the secondary chamber.
- the separating layer only bursts at a defined point. This prevents the separating layer or parts thereof from getting into the mixture and hindering the application process.
- Another advantage of a predetermined breaking point generated in this way is that relatively thick foils, even multilayer foils in the range from 50 to 80 ⁇ m, preferably 60 to 70 ⁇ m, can be pierced with little force (smaller mass of the body).
- the separating device preferably adheres to an annular surface of the piston delimiting the secondary chamber.
- the transition between the annular surface and the inner wall of the secondary chamber may have a sharp-edged area.
- This sharp-edged region preferably runs over part of the circumference, preferably essentially from 60 ° to 120 °, particularly preferably from 70 ° to
- the transition between the ring surface and the inner wall of the secondary chamber is preferably rounded in the rest of the area. This embodiment prevents the film from being torn off completely.
- the separating device is preferably in the form of a single-layer or multilayer film, particularly preferably in the form of a composite film or also sealing film.
- the film preferably comprises at least one metal layer, such as an aluminum layer and / or gold layer, and at least one, optionally two, three or more plastic layers.
- a three-layer film, comprising a plastic outer layer, at least one barrier layer, preferably made of plastic, and a sealing layer has proven to be favorable, the sealing layer also being a plastic film or sealing wax.
- the separating device can have metallized or other plastic barrier layers, plasma-polymerized layers, such as hydrocarbon-containing layers, or ceramic barrier layers, such as SiO x layers.
- the separating device is attached to the annular end face of the piston, for example by heat sealing, gluing, ultrasonic welding or high-frequency welding.
- Suitable outer layers are, for example, layers comprising PET, PP, PE, PTFE, PVC and / or PA, as a barrier layer, layers comprising Al, SiO x , PVDC and / or EVOH, as a sealing layer, layers comprising HDPE, LDPE and / or PP.
- layers comprising PET, PP, PE, PTFE, PVC and / or PA as a barrier layer
- layers comprising Al, SiO x , PVDC and / or EVOH as a sealing layer
- layers comprising HDPE, LDPE and / or PP layers comprising HDPE, LDPE and / or PP.
- the layer thicknesses of the individual foils are in the range from 5 to 60 ⁇ m, preferably from 8 to 50 ⁇ m.
- the separating device can also be designed to accommodate a third component, for example in the form of a foil cushion.
- Advantageous materials for the piston of the mixing capsule include metals such as anodized aluminum, titanium and iron-containing materials such as sheet steel and plastics.
- metals such as anodized aluminum, titanium and iron-containing materials such as sheet steel and plastics.
- a piston may have metallized or other materials that have a barrier effect, vapor-coated or coated plastics. Examples of possible plastics are: PE, PP, PET, PTFE, PVC, polyamides.
- Combinations of the aforementioned materials such as a metal insert, preferably made of aluminum or steel, are also conceivable, which is surrounded on the outside and inside by the plastic. Parts of this type can be produced by injection molding. Production by thermoforming and / or deep drawing of, for example, aluminum composite films or plastic-coated steel sheet is also conceivable.
- the piston can also be manufactured in a 2-component injection molding process.
- an inlay is first manufactured, which is then extrusion-coated with PE, for example.
- the mixed mass is usually discharged from the mixing capsule using a suitable applicator.
- a suitable applicator usually has a plunger which moves the piston of the mixing capsule in the direction of the dispensing opening via lever action.
- dead spaces must be avoided.
- Such dead spaces can be a problem, particularly in the case of highly viscous masses, and have a disadvantageous effect if the total volume of the mixed mass is small compared to the volume of the dead space. If the dead space is to be kept as small as possible, it is advantageous if no additional depressions, for example in the form of a channel, are embedded in the piston and / or the end wall of the main chamber.
- the piston is preferably designed in such a way that it can be deformed, in particular plastically deformed, when it is deployed.
- the deformation is preferably carried out in such a way that the piston adapts to the design which the mixing capsule has at the end at which the dispensing spout is located.
- the piston which has at least one secondary chamber, consists of a deformable material or comprises one.
- a design in such a geometrical shape is also helpful, which facilitates the deformation.
- a design of the piston in the form of a hollow piston open on two sides with a first and a second indentation has proven to be favorable, the first indentation forming the secondary chamber together with the separating device.
- Such a shape can be achieved, for example, by pressing in the bottom surface of a cup made of a deformable material.
- the pressing is preferably carried out by means of a stamp, in particular a hemispherical stamp.
- the piston preferably has one or more sealing lips.
- An additional sealing effect can be achieved by a design which, during the application process, allows the collapsing piston to be spread apart and pressed against the capsule wall. If necessary, the escape of volatile substances, which are in particular in the secondary chamber of the mixing capsule, can be prevented by sealing a sealing film onto the bottom opening of the mixing capsule, into which the piston is inserted.
- deformable piston and mixing body the outer shape of which is destroyed during the mixing process or which is incorporated into the mass to be mixed during the mixing process, is particularly advantageous if an almost complete spreading of the mixed mass is to be ensured.
- a molding can be in the form of a thickening of the piston crown or as a spacer, preferably cylindrical. Since an application device is required to dispense the mixture, which has a displaceable piston rod or a stamp with a defined length that is standardized in trade, it may be necessary to extend the axial length of the stamp over the To extend the molding. In this way it can be ensured that - the deformable piston can be moved into the area of the dispensing spout. It is also advantageous that the risk that the piston rod or the plunger of the application device is jammed when the piston of the mixing capsule is deformed is reduced.
- the components in the main chamber, the secondary chamber and / or the components optionally contained in the separating device include both liquids and solids, preferably in powder form.
- the solids comprise inert fillers, such as finely ground quartz, substances containing SiO x , glasses, reactive fillers of all kinds, the solids optionally being surface-modified.
- the liquids include, in particular, matrix-forming, polymerizable substances, for example polyacids, comprising acrylic acid, methacrylic acid and maleic acid derivatives and copolymers thereof.
- the mixing capsule is preferably suitable for storing, mixing and dispensing glass ionomer cements.
- the dispensing spout on the mixing capsule preferably starts coaxially, but possibly also eccentrically, on the main chamber.
- the dispensing spout is also preferably designed to be closable. Conceivable embodiments are described, for example, in EP 0 157 121 A, where the dispensing spout is pivotally mounted, so that, depending on the position of the dispensing spout, it is closed or opened. It is also conceivable to use a proboscis cap to close the spout.
- the mixing capsule may have a coding. Suitable codes are, for example, color markings, for example in the form of colored rings, labels, prints or electronically readable codes (bar codes). It is also conceivable to apply several codes.
- the coding can contain information about the mixing time, the material, the manufacturer and / or the expiry date.
- the coding can also be done by coloring a mixing capsule component, preferably the spout. Coding the mixing capsule or the substances contained therein via a colored design of the dispensing spout is particularly advantageous if light-sensitive substances are to be stored in the mixing capsule. In order to protect them from incidence of light, it is often necessary to color the piston and / or the cartridge black. If differently colored substances are to be stored in the cartridge, these substances can no longer be identified by the color of the piston, which is now black in color, and / or the cartridge.
- the invention also relates to a method for mixing and dispensing mixtures from mixing capsules, comprising the steps: a) providing a mixing capsule with at least two chambers in which components of the mixture are stored separately from one another by a separating device, comprising a cartridge, one in the Cartridge displaceably arranged piston, a dispensing spout and at least one freely movable body that can penetrate the separating device, b) inserting the mixing capsule into a mixing device with a capsule holder, c) accelerating the mixing capsule, preferably by rapid translatory and / or rotary movement, which means that the at least two chambers separated by a separating device are opened to form a mixing space, d) removing the mixing capsule from the mixing device, e) moving the piston using an application device with a piston rod, as a result of which the mixture produced in step c) is discharged g spout of the mixing capsule on a surface, in particular dental hard tissue or a tooth cavity, is introduced or introduced.
- a conventional application device comprises a holder for inserting the mixing capsule and a displaceable piston rod which is dimensioned such that it can move the piston of the mixing capsule in the direction of the discharge opening.
- Figure 1 shows a longitudinal section through a mixing capsule in the initial state.
- Figure 2 shows the same capsule at the end of the application process.
- Figures 3, 4 show possible preparations of the separating device in supervision.
- the mixing capsule comprises a cylindrical cartridge 10, which is closed at its front end by an end wall 11 and at its rear end by a piston 12.
- a curved spout 14 is formed coaxially to the cartridge axis 13 on the end wall 11.
- the dispensing spout 14 is optionally designed to be closable, for example with a displacement plug.
- the piston 12 is provided with a recess which is coaxial with the cartridge axis 13 and which is closed by a separating device 16 fastened to the annular front end face 15 of the piston 12.
- the separating device 16 separates the secondary chamber 17 formed by the depression from the rest of the interior of the cartridge, which is referred to here as the main chamber 18.
- the piston 12 has a further coaxial depression on the side opposite the secondary chamber, which is adapted to the shape of the secondary chamber.
- the main chamber 18 optionally contains a first, for example powdery and / or granular, component and the secondary chamber 17 contains a second, for example liquid, component of the mixture to be produced.
- the mixing capsule also contains a freely movable, optionally spherical body 19 which is in the initial and / or storage state of the capsule in the main chamber 18 and whose radius is preferably somewhat smaller than the radius of the depression forming the secondary chamber 17.
- the body 19 and the secondary chamber 17 can also have other shapes that deviate from the spherical or hemispherical shape. Freely moving means that the body can basically be moved in all directions and is not impaired in its movement by any guide rails.
- the transition between the depression forming the secondary chamber 17 and the preferably annular end face 15 of the piston 12 is preferably rounded, but may also be formed with sharp edges over an angular range. The sharpness can also be due to a serration be generated. The rounding prevents the separating device from tearing off at this end face inner edge region during the mixing process.
- Separation device 16 are brought to rupture by being overstretched by the impact of the body 19 at the beginning of the mixing process, preferably at the predetermined breaking point.
- the mixing capsule which is supplied by the manufacturer in the state shown in FIG. 1, is placed in a conventional capsule mixing device, in which it is set in vibration, for example, along the cartridge axis 13.
- vibration for example, along the cartridge axis 13.
- rotational movements are possible, possibly in combination with translatory movements.
- the body 19 hits the separating device 16 and penetrates it. Main chamber 18 and secondary chamber 17 are thereby connected to form a common mixing space. The components are mixed together in this mixing chamber during the further mixing process. During the mixing process, the body 19 breaks and is embedded, preferably incorporated, into the mass to be mixed.
- the piston 12 is moved forward in a commercially available application instrument with a plunger 20 until it reaches the position shown in FIG. 2, depending on the material properties of the piston, and preferably has no secondary chamber.
- the deformation preferably takes place while reducing the volume of the secondary chamber only when the annular surface 15 of the piston 12 has come to rest against the end wall of the cartridge. This can be achieved, for example, in that the frictional force between the piston and the inner wall of the cartridge is less than the force that has to be used to deform the piston.
- FIGS. 3 and 4 possible preparations of the separating device 16 are shown in a top view, which enable the mixing capsule to be activated simply and largely completely without components of the separating device being embedded in the mixed mass during mixing.
- the preparation is preferably carried out by pre-damage to the film used for the separating device, for example by exposure to radiation.
- the mixing capsule is usually used together with another device.
- a device in the sense of the invention is to be understood on the one hand as a device that is used to activate the mixing capsule, preferably a device that can set the mixing capsule in translatory and / or rotary motion, and on the other hand, a device that is used to discharge the mixed capsule Mass from the mixing capsule facilitates, preferably a device comprising a plunger or a displaceable piston rod.
