Definitions
- the invention relates to a device for storing and mixing substances, in particular dental materials, preferably filling materials, such as composites, glass ionomer cements and compomers.
- a multi-component adhesive packaging for small quantities is known from DE 90 00 839 U, the components of the adhesive being arranged in cup-shaped chambers between two films connected to one another. By tilting one bowl, its contents can be transferred to the other bowl.
- EP 0 916 593 A2 describes a flexible packaging for separate storage and simultaneous dispensing of two materials of a polymerizable system, in particular an addition-crosslinking dental impression material, in cup-shaped depressions.
- EP 0 115 562 A1 describes a portion pack for storing and mixing silver and mercury, comprising two portion packs which are formed in one piece from a pair of foils welded to one another to form two separate portion pockets.
- a multi-component chamber bag for storing liquid substances is described, for example, in DE 199 27572 A1.
- None of the devices mentioned enables both the storage of substances and a largely loss-free mixing of these substances into a pasty mass using the storage device.
- BESTATIGUNGSKOPIE Accordingly, it is an object of the present invention to provide a device which facilitates the storage and mixing, in particular of pasty substances.
- the invention has the following advantages: In the device according to the invention, the substances to be mixed can be optimally packaged in the required amount. Incorrect dosing and an incorrect mixing ratio are largely excluded.
- the substances to be mixed are present in the state to be mixed after the cover and bottom films have been removed and do not first have to be expressed from different vessels or transferred to a container for mixing.
- the storage area is part of the mixing area. This means that 100% of the pre-metered quantities to be mixed are available for mixing.
- the mixed paste can thus be largely used completely.
- the base film After the cover film has been removed, the base film also serves as a mixing surface and its material properties can be matched to the reactivity of the substances to be mixed.
- chamber is understood to mean a cavity of flat shape which is closed to the outside and which is formed by connecting at least two foils (base or bottom foil and top or top foil), for example by gluing, sealing, heat sealing or high-frequency sealing, and is formed by or pulling apart the films in the sealable area can be opened completely.
- the arrangement of the chambers is arbitrary, but is preferably carried out in such a way that mixing after activation of the device is possible without any problems.
- the chambers are preferably arranged essentially centrally, possibly along an axis, on the non-activated device.
- the volume of the at least two chambers can optionally be increased in this area by slight deep drawing, in particular of the cover foils.
- the chamber volume to be selected depends on the intended use and is in principle not restricted. Suitable chamber volumes are usually in the range of 0.01 to 10 ml.
- essentially not deep-drawn or only slightly deep-drawn means that the ratio of the diameter to the depth of the chamber is greater than or equal to 5: 1, preferably greater than or equal to or shallower than 10: 1.
- the chambers can have any shape, are preferably round or oval. In the case of two-component and multi-component materials, an arrangement of oval chambers one behind the other may be useful for reasons of space, the small ellipse radius preferably being arranged essentially along the longitudinal axis of the device.
- Drop-shaped chambers are also also useful, the “drop tip” pointing to the corrugations that may be present on the film or a tab that may be present.
- the device can be opened more easily since the force initially to be applied for pulling on or peeling off the film is low in the area of the drop-shaped sealing seam tip and only gradually increases to the force which is required for pulling on the film in the area of the full sealing seam width.
- the sealing area surrounding the chambers has a shape with at least one area narrowing in one direction, which points in the direction of a pull tab that may be present.
- each chamber or its sealing region has a drop tip in the direction of any corrugation that may be present.
- the droplet tips of the sealed seams can also lead to a common tip.
- Activating in the sense of the invention means opening the device by pulling the top or top film off or pulling it off the base or bottom film, exposing a largely flat mixing area on which the substance or substances to be mixed are located.
- the device may have a pocket in which there is an applicator suitable for mixing and application.
- a bag is to be understood as an open container on at least one side.
- the bag can be shaped by a sealing seam, individual sealing bars and / or sealing point.
- mixing area area that is necessary for mixing the material portions
- this seal is completely opened when the device is activated and may also have a sealing seam tip pointing towards the pull tabs or corrugations, in order to make it easier for the foils sealed to one another to be released.
- the applicator is preferably in the form of a spatula and can be made of wood, metal or a suitable plastic.
- the applicator may have an angled shape or, depending on the width, a non-rectangular or round, beveled end. An angle in the range of 5 to 45 ° with respect to the longitudinal axis is preferred.
- a mixing block has a certain height in relation to, for example, a table surface as a base and thus enables mixing even using a straight spatula.
- the base film and cover film are components of a single film, which can also be a multilayer film.
- the flat mixing surface is formed by pulling apart the base or bottom film and the cover or top film without the cover or top film being completely removed or removed.
- flat mixing area within the meaning of the invention is to be understood as an area that does not wrinkle when mixed with an applicator and essentially has no depressions or only negligibly small depressions for the intended use.
- the mixing area has an area in the range from 5 to 300 cm 2 .
- the device preferably has brackets in the edge region which are intended to facilitate handling of the device when mixing.
- Such holders can have the shape of corrugations in the edge region of the device and can be introduced into the film, for example, by embossing.
- adhesive points can also be advantageous to apply adhesive points as a facade coating or as double-sided adhesive points or adhesive strips on the film, which make it easier to fix the activated device to a surface.
- adhesive areas can, if necessary, be covered on the folded film of the device or with an additional cover film to prevent premature adhesion.
- the device may be sufficient if the device has individual adhesive points only in the peripheral areas. However, it is also conceivable that the films of the device are designed to be almost completely adhesive on the side facing away from the substance. In this embodiment, the mixing device could be positioned almost immovably on a surface.
- the device can also be applied to a block with an adhesive surface.
- Each side of the block can be used for multiple blending applications until a fresh sticky sheet is used if dirty or worn.
- the individual sheets or components of the block are preferably not completely coated with an adhesive, but instead have an area that is adhesive-free, which enables the individual sheets or components to be peeled off.
- an adhesive block that has a partial adhesive coating in a surface area indented by 1 to 5 mm (ie smaller) than the activated device to be fixed thereon. This facilitates, for example, positioning the device on the adhesive block in the desired manner.
- the application of only one adhesive area in the edge area of the device and the mutual adhesion of several devices enables one advantageous packaging in the form of a dispenser. After a device has been removed from the dispenser, a new device for removal is provided in an opening.
- Suitable adhesives include in particular encapsulated adhesives (nanoparticles) that only develop their adhesive properties when they are pressed onto a surface, for example.
- the adhesives are preferably of such a nature that they can be removed again without residue from a surface, for example a table or mixing block as a mixing base.
- a mixing plate with clamping strips at both ends can also be used to clamp the pull tabs during the mixing process.
- the device has at least one chamber, but possibly also two, three, four or more chambers into which substances to be mixed can be introduced.
- the presence of a chamber can be sufficient, for example, if the stored mass tends to separate during storage and has to be mixed again before use.
- the device can preferably be produced in a simple and inexpensive manner by “folding” or “folding” a single film and sealing at least in the edge region of the chambers to be formed, into which the substance to be stored is introduced before sealing.
- the method for producing the device according to the invention comprises the following steps: a) providing a base or bottom film, b) if necessary, partial deep-drawing of the film, so that the ratio of diameter to depth of the deep-drawn area is greater than or equal to 5: 1, preferably greater than or equal to 10: 1, c) applying at least one substance to the film which, depending on the or top film used and its deformation by deep drawing has a sufficiently high stability so that it cannot escape laterally during the sealing process, d) sealing a cover or top film, preferably immediately after step c) without the base or bottom film from step a) was deep-drawn, the base or bottom film and top or top film may be components of a film.
- the sealing seam created in step d) is self-contained.
- it is round, oval, rectangular, diamond-shaped or teardrop-shaped.
- Another method for producing the device comprises the following steps: a) providing a base or bottom film, b) folding over the film preferably to form a fold area c) producing at least one sealing seam which intersects the fold area, at least two pocket-shaped arrangements being formed, d) separate introduction of at least two substances into the corners of the pocket-shaped arrangements, e) sealing of the pocket-shaped arrangements.
- the pocket-like arrangements in the folding area can optionally be widened by pressure parallel to the main direction of the sealing seam. This facilitates the introduction of the substances and prevents contamination of still unsealed areas with substances to be introduced.
- the following method has proven itself for producing a device which is suitable for storing three components to be mixed: a) providing a base or bottom film, b) applying a first substance at a point in the later folding area, c) folding over the film, preferably forming a folding area, d) producing two intersecting sealing seams that also cut the folding area, one Chamber and two pocket-shaped arrangements are formed, e) separate introduction of at least two substances in the corners of the pocket-shaped arrangements, f) sealing the pocket-shaped arrangements.
- the sealing seams can have any shape.
- the substance to be stored is flowable, it should preferably have a viscosity in the range from 0.5 * 10 "3 to 10 * 10 3 Pas.
- the speed at which the chambers are sealed is based on the viscosity or the stability of the substances to be sealed.
- 'A sufficiently high speed also enables the sealing of relatively liquid substances between a largely flat top and bottom film, since the substance needs a certain time after being applied to the bottom film, depending on its surface tension and its viscosity, in order to be distributed over it , or a certain time is required to spread in the area formed by the sealing of the top or cover film on the bottom film and to flow to the actual sealing area. This area should therefore be sealed in good time.
- a film is first provided, a certain amount of substance or substances to be mixed is applied to it, the film is preferably folded in the middle and with itself omitting at least one chamber in which the substance or the Substances are sealed, peelable, and the at least one chamber can also be located in the folding area.
- the chambers are formed by sealing or gluing at least one or two foils at least in the edge region of the chamber to be formed, leaving a cavity in which the substance to be mixed is located.
- one or more of the sealing areas that form the chamber can also be replaced by a fold or fold that is created when the film is bent.
- the course of the sealing seam is not self-contained, but forms at least one closed chamber with the folding. Sealing can be carried out in the manner familiar to the person skilled in the art, for example by heat sealing or by means of ultrasonic welding.
- the film areas that are pulled apart to open the device do not match the film areas with which the device can be fixed, in particular stretched, after activation.
- a film is preferably selected which, when folded, forms no or only small permanent kinks or folds the film in the fold area in such a way that when the cover film is pulled off or the cover film and base film are pulled apart, no depressions remain in the fold area which could impair the mixing result , It is also conceivable not to fold the film over a sharp edge, but only to fold it loosely, so that a bead-like bulge remains in the folding area.
- Films are particularly suitable, including multilayer films, which do not deform and / or reject permanently when being pulled off or pulled on, in particular show no tendency to roll up, so that the formation of a largely flat mixing surface is ensured.
- the film used has a tendency to curl, it can be advantageous to have it offset in the production by 90 ° to the longitudinal axis of the device, in order to activate the device due to the curling tendency of the film to have a restoring effect around the fold area of the film when producing the film To prevent or reduce the device.
- Peel films are usually used, which can be separated from one another in a non-destructive manner when they are pulled open at the sealing areas.
- PE polystyrene resin
- PP polystyrene resin
- PA polystyrene
- PET polystyrene
- PVDC polyvinyl styrene
- PVC polyvinyl styrene resin
- EVA EVA
- EVOH COC
- COC paper-plastic composite films or a PE / paper composite
- a combination in the film sequence paper / aluminum / paper / PE is preferred.
- the films preferably have barrier layers in the form of metal, such as Al, or ceramic, such as SiOx or AlOx.
- the device according to the invention and the method according to the invention are suitable for storing and mixing any substances, the substances usually being present in a pasty consistency after the mixing.
- monofilms or laminate foils without an oxygen-tight barrier layer such as aluminum are recommended.
- these foils should, for example, form the best possible water vapor barrier for the storage of so-called RM-GIZs (resin modified glass ionomer cements).
- Monofilms such as sealable PE or PP foils with a corresponding thickness between 80 and 1000 ⁇ m or plastic laminate foils with additional plastic barrier layers such as PET, EVOH, EVA, PA, COC, PVC, PVDC or thin aluminum or ceramic vapor deposits (AI 2 O 3 ⁇ SiO x ) are conceivable.
- Thick monofilms of greater than 200 ⁇ m can also be injection molded and, in the case of the one-piece embodiment, may be made thinner at the kink.
- the substances which can be stored in the device and miscible with the aid of the device can be in the form of powder, granules, tablet form, paste or liquids.
- the substances are in particular dental components
- the device can also be used to store impression compounds based on polyether or silicone.
- the device is also suitable for storing and mixing multicomponent adhesives, such as epoxy adhesives, or multicomponent paints.
- multicomponent adhesives such as epoxy adhesives, or multicomponent paints.
- a color tone individually mixed from two different colors can also be provided by at least partially mixing two color portions.
- the substances or the outer layer of the base film should be coordinated with one another in such a way that the substances remain on the base film when the cover film is removed and are not at least partially removed with the cover film.
- suitable coating materials either by non-stick coating of the cover film with, for example, silicone oil or silicone lacquer or ESA lacquer (erucic acid amide) or PTFE in this area, if appropriate as a facade coating and / or applying an adhesion promoter or applying or incorporating a microretentive surface the base film. It is also conceivable to coat the substances to be stored with a suitable coating agent. Other suitable release agents can be release wax or sealing wax, which has a non-stick effect in the unsealed area. Similar effects can also be achieved by applying a nano-coating, as described for example in VDI yogaen 1/01 on page 9.
- the sealing area forming the chamber (s) is interrupted by a narrow, unsealed area In this area, the base film is separated from the cover film by a channel-shaped cavity which surrounds the chamber and is formed in the cover film as a deep-drawn profile.
- the cover or top film from the base or bottom film is divided into two separate miscible portions on the exposed mixing area. This embodiment has proven to be particularly advantageous in the dental field for filling materials if the amount of substance stored in the device is sufficient for more than one cavity.
- this embodiment allows only a portion of the stored amount of substance to be mixed and processed initially, while the second portion remains unmixed on the mixing area.
- an elongated shape for example the shape of an ellipse or a rectangle.
- Figure 1 shows an embodiment of the device according to the invention in supervision before activation.
- Figure 2 shows a further embodiment of the device in supervision.
- Figure 3 shows the embodiment of Figure 2 in cross section.
- Figure 4 shows an embodiment of the device after activation in supervision and in cross section.
- Figure 1 shows an embodiment of the device according to the invention in supervision with a base film (1) and a cover film (2), the device having a pocket (5) for receiving an applicator (6).
- the corrugation (4) in the edge region of the device is also indicated.
- the dashed lines (3) are the areas in which the base film (1) and cover film (2) must be sealed so that they can be peeled so that the corresponding number of chambers (7, 8) can be formed.
- the cover film has a tab (11) for easier removal.
- the cover film is connected to the base film in such a way that it cannot be removed completely when the device is activated. This can be achieved, for example, by a wide sealing seam at the end of the cover film.
- FIG. 2 shows a further embodiment of the device in a top view, the base film being folded in the middle so that the cover and base films (1, 2) form a common film.
- the device also contains an applicator (6), which is located in a pocket (5).
- the preferred drop-shaped shape of the sealing area (3) surrounding the at least one chamber is also indicated.
- One tip of the drop points in the direction of the corrugation (4), in the vicinity of which there may also be a pull tab, the other in the direction of the folding area.
- the sealing areas (3) which form the two chambers are connected to one another via an hourglass-shaped sealing area (12).
- Figure 3 shows the embodiment of Figure 2 in cross section.
- the dashed areas (3) are sealed peelable.
- the substances (9, 10) to be mixed are located in the chambers (7, 8).
- the film is not folded over a sharp edge, but only loosely folded over and forms a bulge (14) in the folding area.
- FIG. 4 shows the device according to FIG. 2 after the activation process with a flat, exposed mixing area on which there are two portions (A, B) of the substances (9, 10) to be mixed, which were originally sealed in two chambers. Also shown is a preferred tab-shaped holder (13) in the edge area of the device, which, together or instead of the corrugation, enables the device to be tensioned in order to achieve a largely flat mixing area.
- the device according to FIG. 2 can also be designed in such a way that the two foils are not arranged one above the other in the area of the corrugation, but laterally offset. This can be achieved, for example, through a largely point-symmetrical punching shape.
- a similar arrangement can be achieved if the mirror-symmetrical film is not folded opaque but folded laterally offset. It is also possible to fold the device off-center, so that one of the two film areas only partially overlaps the other film area when not open.
- the device is suitable, for example, in the dental field for storing and mixing dental filling materials in an amount sufficient to supply one or two tooth cavities.
