Abstract: In the method for venting and eliminating liquid material of a dispensing appliance prior to dispensing, the air as well as unusable material are eliminated via a deviating channel and the conditioned material is dispensed via a dispensing channel. The device for implementing the method for eliminating unusable liquid material and for venting a dispensing appliance is provided with a valve assembly for selectively connecting the inlet area of the device with a deviating channel or with an outlet. The deviating channel is connected to a collecting container having venting means. The method and the device according to the invention allow advantageously venting a multicomponent dispensing appliance and leveling the components as well as eliminating incompletely mixed components in the starting phase after the latter have left the mixer elements, thereby ensuring a flawless application. In an advantageous development, a device is provided that avoids the occurrence of an overpressure during dispensing.

Abstract: The dispensing device for single use includes a multicomponent cartridge (1), a mixer (8) having a mixer housing (9), as well as closure means for closing the outlets (4, 5) of the multicomponent cartridge. These closure means are connected to the mixer housing and comprise a respective closure stopper (13, 14) for each outlet that is insertable in an outlet (4, 5) of the multicomponent cartridge and is deformable such that upon rotation of the mixer housing relative to the cartridge, the closure stoppers (13, 14) are removed from the outlets (4, 5) of the multicomponent cartridge. Such an easily removable closure by means of deformable closure stoppers allows a very economical manufacture of dispensing devices that are intended to be used only once at it is required in medicine and in other fields.

Abstract: The invention relates to a system for dispensing two components, which comprises a syringe or cartridge, a closing cap and a mixer. The aim of the invention is to provide a system of the aforementioned kind wherein the closing cap is detachable fastened on the syringe or cartridge and the mixer is non-detachable fastened on the cartridge. For this purpose, the fastening means are configured accordingly. The inner bead on the closing cap, in the zone of transition to the cap interior, is provided with a bevelled section that rests on the retaining cams or the retaining bead of the cartridge, while the retaining means on the mixer engage behind the retaining means on the cartridge, thereby forming a non-detachable connection. The invention provides an inexpensive and yet reliable system for dispensing two components, especially for use in dental and medical technology.

The mixer includes mixing elements comprising a transversal edge and a following transversal guide wall and at least two guide walls with lateral end sections and at least one bottom section disposed between said guide walls, thereby defining at least one opening on one side of said transversal edge and at least two openings on the other side of said transversal edge. In addition to a high mixing efficiency and a low pressure drop, a mixer of this kind provides reduced dead volumes and is thus more effective than mixers of the prior art.

Abstract: A multicomponent dispensing device for liquid and powdery materials comprises a blister part having at least two chambers that are arranged adjacent each other and sealed by means of a film, a blister base with at least one dispensing member acting upon the chambers, an outlet, and closed channels or channels with sutures arranged between following chambers and/or between the last chambers with respect to the outlet. The blister part is fastened to the blister base in such a manner that the sutures yield so that the materials may pass through. The dispensing device comprises a static mixer. By using dispensing members for the simultaneous discharge of chamber rows and the integration of a mixer, a dispensing device is realized that allows, by means of inexpensive elements, a very precise delivery of well mixed substances.

Abstract: The static mixer for two components comprises a housing with an inlet section and mixing elements that are arranged in the housing. At least one of the mixing elements is designed, in contrast to mixing helixes of the prior art, as a disk-shaped shear plate having a passage in its disk. Such shear elements allow mixing even of smallest quantities that are possibly dispensed drop by drop, as higher shearing rates are produced near the passages of the shear plates during dispensing and vortices are created on their outlet sides. This is very advantageous especially in medical applications of such mixers.

Abstract: The invention relates to a system for dispensing two components, including a syringe or cartridge and a mixer. The system is characterized in that the edges of the mixer inlet openings on the cartridge end and the transfer channel outlets linked with the cartridge outlets are disposed and configured to allow a vacuum-free replacement of the mixer. The planes of the openings on the adapter outlets or on the cartridge outlets or the planes of the openings of the mixer inlets form an angle, especially an angle of 90°, with the longitudinal axes of the outlets or inlets. The inventive systems allows removal of the mixers without producing a vacuum, thereby preserving the filling level of the two components and allowing a correct mixing ratio from the outset once the new mixer is placed on the syringe or cartridge.

Abstract: The applicator for a double cartridge includes an adapter for connection to a mixer attached to a double cartridge as well as a dispensing slot, the side of the enclosure that is turned towards the glued substrate forming an angle with the longitudinal axis of the adapter which is comprised between 5° and 90°. The underside of the enclosure is essentially continuously curved. Due to the curvature of the enclosure, the material that is to be glued, e.g. lung tissue, is first smoothened and immediately thereafter evenly coated with adhesive. This allows a reliable application of such an applicator in medicine or in the industry.

Abstract: Disclosed is a dispensing device comprising a dispense mechanism and a multicomponent syringe. The fastening parts of the syringe are embodied such that the syringe can be inserted into a holder on the dispense mechanism on the plane of the reservoirs thereof and perpendicular to the plane formed by the handle and the triggering lever of the dispense mechanism. The fastening means on the syringe and the insertion opening on the syringe holder of the dispense mechanism are provided with coding elements that ensure that the syringe is inserted in only one direction, thus preventing non-certified syringes from being dispensed by means of such a dispense mechanism. In a preferred embodiment, ergonomically shaped syringe flanges can optionally be used for dispensing the syringe in an optimal manner by hand with the aid of a dispense mechanism.

Abstract: The dispensing device for single use includes a multicomponent cartridge with a closure and a mixer. The cartridge and the mixer form an interconnected unit and the closure, arranged between the outlets of the cartridge and the inlets of the mixer, is configured as a valve arrangement in order to establish a connection between the cartridge outlets and the mixing elements of the mixer after performing a relative movement between the mixer and the cartridge or syringe. In certain embodiments of the invention the connection is effected by rotation of the mixing unit relative to the cartridge, and in other embodiments of the invention by axial displacement of the mixing unit relative to the cartridge. This results in a disposable dispensing unit that can be economically produced and is particularly easy to use.

The individual components (27, 28) are stored in respective containers (2, 3) that are arranged side by side, and a valve assembly (8) is arranged in the transfer area (7) between the outlet area (26) of the container (3) for storing the second, liquid component (28) and the liquid inlet (25) of the container (2) for storing the first component (27). Such a device allows an unproblematic storage of the different components without a local separation of the containers and an efficient mix thereof. This applies especially if the first component is a powder or a granular or porous substance, e.g. bone cement or bone replacement material.
