The present disclosure relates to a mixer having a mixer housing which encloses a mixing chamber, an input part which can be connected to the mixer housing and has at least two input openings for the components to be mixed, and a mixing element, at least some sections of which extend into the mixing chamber, wherein each of the input openings is flow-connected to the mixing chamber via at least one input duct, wherein there is also in the input part at least one compensation duct which connects the input openings to each other, and/or at least one holding chamber is provided in the mixing element.

Mixer having compensation channel and/or reservoir chamber

The disclosure relates to a specifically static mixer for mixing two components, with a housing, in which a mixing element is accommodated, and an input part with a first intake and a diametrically opposite second intake, wherein, within the input part, a first channel is formed between the first intake and the mixing chamber and a second channel is formed between the second intake and the mixing chamber. The first channel extends radially inward from the first intake and opens into a central opening in the cover. The second channel has two partial channels as storage chambers not leading into the mixing chamber, and two intake sections located radially within the storage chambers and leading into the mixing chamber. The intake sections branch off the respective storage chambers, extend inward in the opposite direction to the first channel and open into the central opening in the cover.

Mixer and method for mixing two components

The present disclosure relates to a mixer for mixing pasty components, comprising a mixing case extending along a longitudinal axis and having at least one inlet, preferably two inlets, and an outlet, and comprising at least one mixing element received in the mixing case, which defines a plurality of chambers together with the mixing case, said chambers being arranged successively and/or adjacently along a flow path from the inlets to the outlet. The chambers are defined by transverse walls, each extending perpendicularly to the longitudinal axis, and four side walls that each extend parallel to the longitudinal axis, and adjacent chambers are interconnected by a flow by means of through-openings provided in the side walls, the mixing element comprising two strips forming side walls, which are connected by a web that forms other side walls and is perpendicularly arranged in relation to the strips, a first group of chambers having first through-openings arranged in the web, which extend up to a strip, and a second group of chambers comprising second through-openings positioned at a distance to at least one strip in the web.

Mixer

The present disclosure relates to an application system with a cartridge having at least one container with a respective outlet, and a closure element that can sealingly close the outlet of the at least one container when the cartridge is in the delivery state. When in the storage state, the cartridge sealingly closes the closure element. When the cartridge is in the state of use, the closure element can be removed therefrom and an accessory can be connected to the outlet of the at least one container. According to the invention, the cartridge or the closure element comprises, in the delivery state, a connecting element which cannot be removed without being damaged, and the cartridge or the closure element, in the storage state, is connected via a connecting element that cannot be removed without being damaged, to a closure element or the cartridge.

Application system

An application system is presented having a cartridge, at least one first accessory part, for example a stopper, and at least one second accessory part, for example a static or dynamic mixer. The cartridge has at least one container with an outlet opening and at least one outlet connected to the container via the outlet opening on the end face of the cartridge, wherein the at least one outlet can be connected to the at least one first accessory part and the at least one second accessory part such that a seal is produced between the outlet and the respective accessory part. At least one separate seal plane is provided for each accessory part.

Application system with improved seal

Syringe for dental use

Medical cartridge

The invention relates to a container () for storing and discharging at least one component with at least one chamber (), which is sealed on a first side by a plug (), and with one applicator () attached on the first side. A flow connection between the at least one chamber () and the side of the applicator () facing away from the at least one chamber () is opened by a relative rotational movement of the applicator () to the container () and a subsequent axial relative movement of the plug () to the container () and the applicator (), in particular due to pressure of the at least one component on the plug (). Furthermore, the invention relates to a method for storing and discharging at least one component.

Container for storing and dispensing at least one component and method therefor

The invention relates to a piston, in particular, for use as a discharge and/or locking piston of a cartridge comprising a base body () having a lateral wall provided with sealants () and a front-end wall having a vent (). A locking element () is mounted rotatable in the vent (), whereby a venting channel () can be opened or closed by the relative rotation of the locking element () in the vent (). Additionally, the invention relates to a cartridge configuration having such a piston.

Piston and cartridge arrangement having said piston

The invention relates to a cartridge system with two containers () respectively having an outlet connector (), and a common connection section for a mixer () having a positioning aperture (), and with a static mixer () with inlet connectors () and a positioning element (). The connection section of the cartridge comprises a ring () having an inner thread () that surrounds the outlet connectors (), whereby the mixer () has an outer thread (). Further, the invention relates to a static mixer () for a cartridge system of this type.

Cartridge system and static mixer therefor

The invention relates to a delivery device having two containers () that are connected with each other and a mixer (). Preferably, the mixer can be connected with the containers () by an outer thread (). Thereby, the mixer has a coupling element (), a mixer housing () rotatable relative to it and a mixing element () that is housed in the mixer housing ().

Mixer and dispensing device

The invention relates to a double cartridge (), a mixer () and a combination consisting of a double cartridge having a mixer. The cartridge has a guiding channel () that is formed between protrusions (). The mixer () has at least one guiding rib () to guide the mixer () in the double cartridge ().

Double cartridge, mixer therefor and combination of double cartridge and mixer

The invention relates to a mixer () for mixing two components, in particular, a hardenable dental material. The mixer () has a mixer housing (), a mixer element () and a cover (). The mixer () has an annular chamber () that is in fluid communication with the mixing chamber of the mixer housing (). The chamber () is defined by the cover (), and by a plate () that is provided on the mixer element (). The first of the inlet connections () leading into mixer (), ends in chamber (), while the other ends downstream of plate () in the mixing chamber.

The invention relates to a polymerizable dental material containing a) at least one curable aliphatic and/or cycloaliphatic monomer system having a refractive index that is measured at 23&#xb0; C. and a wavelength of 589 nm of less than or equal to 1.50 that contains at least one aliphatic and/or cycloaliphatic bis(meth)acrylate and/or at least one aliphatic and/or cycloaliphatic bis(meth)acrylamide; and b) 15 to 80% by weight relative to the total mass of the dental material of at least one filler selected from the group of fused silica having a refractive index that is measured at 23&#xb0; C. and a wavelength of 589 nm of 1.45 to 1.47, or cristobalite with a refractive index that is measured at 23&#xb0; C. and a wavelength of 589 nm of 1.48 to 1.49, or combinations thereof. The radically polymerizable dental material has excellent storage properties and is formulated, in particular, as a two-component mixture containing components A and B. Subsequent to mixing components A and B, the polymerizable mixture cures quickly in the conditions present in the mouth and forms cured masses having outstanding mechanical and optical properties. The cured products can be used, in particular, for producing crowns and bridge material and as core buildup material.
