Moreover, the invention relates to a dispenser comprising a reservoir having at least one outlet opening, which has a first cross section, which has a minimum and / or a maximum diameter, and a device for dispensing as mentioned above.

STATE OF THE ART

Devices for the controlled discharge of material are in different

Executions known. The dispensing device consists for example of a nozzle (tip), which runs down to a - due to the internal thread - slightly widened nozzle head conically down, but otherwise has no grooves.

Occasionally have nozzles (tips) and wings in the area of the nozzle head, which should give a better grip when placing the nozzle (tip) on the reservoir or partly only perform optical function.

Often it happens that nozzles (tips) are used again after a first use. The same also applies to the reservoirs screwed therewith, e.g. Cartridges containing the material to be delivered.

A disadvantage of the known devices, however, is that the user when dissolving the

Connection between nozzle (tip) and reservoir, e.g. a cartridge is confronted with a contaminated spout of the reservoir. In case of a

However, reuse may cause a contaminated spout of the reservoir

Problems lead, since the existing remainder of the outlet of the reservoir easily can stick or clog, which makes further use of the cartridge often impossible or at least greatly aggravated. Cleaning utensils, which consist for example of pointed objects for insertion into the outlet opening, are often not available or only in insufficient execution.

The Utility Model DE 297 17 450.9 "tip-on" tip for a plastic, e.g., silicone, cartridge "discloses an incipient tip intended to counteract the interfering contaminants of the tip itself. OBJECT OF THE INVENTION

Based on this, the object of the present invention is to provide a device for dispensing a material and a dispenser, which allow in a simple manner to use a reservoir several times at intervals, i. to interrupt the spreading of the material.

To the aforementioned possibility of a

Shortening of the nozzle (tip) or a broadening of the outlet opening to

clarify, a scissors symbol can be used, which is attached to the nozzle body.

The device can be used to dispense a homogeneous material as well as multi-component material. In the nozzle (tip) itself, a mixing helix can be introduced, which allows the mixing of different material components passing through. In principle, these mixing spirals separate a material strand flowing through them in a defined manner and subsequently recombine the divided material strands. In this way, the originally stored separately in the cartridge chambers components during the

Passing through the mixed structure mixed.

The dispenser according to the invention comprises a storage container with at least one

Outlet opening having a first cross-section having a minimum and / or a maximum diameter, and a device for dispensing according to one of the preceding claims, which can be removably connected to the reservoir.

The outlet opening of the dispenser can be delimited by a mouth wall, the mouth wall having a predetermined material thickness. In a preferred embodiment, the dispenser is characterized in that the projection of the device for dispensing in cross section has a maximum diameter which is smaller than the minimum diameter of the outlet opening of the

Reservoir.
