Problems solved by technology

[0005] The dispensing devices known from the prior art do not ensure that the dispensing pipe can be arranged cleanly at the spraying part in a simple manner without damaging the mixing drum in the application
There is also a risk that the dispensing tube cannot be placed cleanly at the injection part so that when the syringe is extruded, the components can emerge laterally at the junction between the injection part and the dispensing tube

Embodiment Construction

[0057] figure 1 A dispensing device according to the invention is shown for mixing and dispensing multi-component substances according to a preferred embodiment. Multi-component cartridge 1 in figure 1 is designed as a double syringe with a container having two substantially cylindrical chambers 2, 3 fixedly connected to receive the different components. The components in this example are the two components of a two-component glue, which are only allowed to mix with each other shortly before being distributed to the objects to be glued. However, there are also other components that can be stored in the chamber, for example in bulk for dental applications. Primarily, the present multi-component cartridges are suitable, especially in all applications where small amounts of components should be applied at once.

[0058] The multi-component cartridge has an inlet end 40 and an outlet end 50 . The inlet port 40 comprises inlet holes 41 , 42 through which the chambers 2 , 3 can ...

Abstract

The invention relates to a multi-component cartridge. Concretely, a dispensing apparatus for mixing and dispensing multi-component masses including a multi-component cartridge or syringe having a plurality of chambers, a mixer element having a longitudinal axis and a mixer housing placed over the mixer element. The mixer element and the multi-component cartridge are formed by unit elements, wherein each chamber is provided with a dispensing opening, which can be closed by a closing element fixed at the mixer housing. The outer surface of the mixer element and the inner wall of the mixer housing have a cooperating guide element which only allows a displacement of the mixer housing at the mixer element along the longitudinal axis of the mixer element. The mixer housing is axially displaceably connected to the multi-component cartridge through a connecting element, wherein, the multi-component cartridge can be transferred from a closed position locking the dispensing opening to a dispensing position releasing the dispensing opening.

Description

technical field [0001] The invention relates to a dispensing device for mixing and dispensing multicomponent substances according to the preamble of claim 1 . Background technique [0002] Patent DE 10254409A1 describes a device for mixing and dispensing multi-component substances. The device comprises a cartridge having at least two cylindrical chambers arranged in parallel for receiving a component and having a corresponding piston for extruding the component. The chamber has an exit hole, which is covered and locked by the circular inner surface of the cap. The cap has a curved outlet tube surrounding the mixing drum. The mixing drum is of flexible design and bends accordingly in the direction of the outlet pipe. The mixing drum is attached to a transverse wall formed at the cylindrical protrusion of the cartridge head. The transverse wall is held in the recess of the cap with respect to rotation. The cap is lifted from the locked position by applying pressure from t...
