Definitions
- the invention relates to a two-component cartridge according to the preamble of Claim 1.
- the components contained in the cartridge are in a mixing cannula placed on the cartridge is mixed together.
- a mixing cannula placed on the cartridge is mixed together.
- Cartridge and mixing cannula connected to each other via a detachable bayonet lock.
- the conventional embodiment has a tube with a partition, making two crescent-shaped Outlet openings are formed.
- the cartridge outlet openings are formed by two holes spaced apart.
- the stake in this case consists of a soft plastic and seals against the edge of the holes. At this Embodiment must be taken to ensure that those running through the insert Channels are aligned with the aforementioned holes in the cartridge.
- the two-component cartridge 1 has a tube 2 through which a partition 3 runs, which divides the cartridge into two chambers 4 and 5. Through the partition 3 two crescent-shaped outlet openings 7, 8 are formed in the tube 2.
- a mixing cannula 9 is placed on the cartridge 1 by means of a bayonet catch 6.
- the lower part of this mixing cannula 9 overlaps an insert 10.
- This insert 10 overlaps tube 2 with its lower part and sits on one with its lower end the tube 2 surrounding shoulder 11.
- the partition 3 has a groove 12 at its upper end. In this groove 12 engages Middle web 13 of the insert 10. This central web 13 can be up to the top of the Bet 10 run.
- the passage openings have a shape that causes the two components of the chambers 4 and 5 already when entering the Mixing chamber 14 of the mixing cannula 9 are mixed together.
- Two lateral passage openings 15 run from the outlet opening 7 of the chamber 5 coaxially through the insert 10 to the top of the insert 10. From the The outlet opening 8 of the chamber 4 extends two further through openings 16 coaxially to the upper end of the insert 10. Between the passage openings 15 and the Through openings 16, two further through openings 17, 18 are arranged. The lower The entrance of the passage opening 17 communicates with the outlet opening 7 of the chamber 5, during the entrance of the passage opening 18 with the outlet opening 8 of the chamber 4 communicates.
- the passage openings 17, 18 each have an oblique lip 19, 20, the slopes of which are opposite to each other.
- the Partition 3A in turn has a groove 12A into which the lower end of the central web 13A engages. This central web 13A extends axially through the insert 10A.
- the Outlet opening 7A communicates through opening 17A, while with the Exit opening 8A communicates the through opening 18A.
- the lower part of the Mixing cannula 9A overlaps insert 10A.
- the passage opening 17A has a first one Exit 21 on.
- the passage opening 18A also has a first outlet 22.
- the Passage opening 17A includes a circumferential direction of insert 10A Channel 23, which opens into a second output 21A.
- the passage opening 18A faces also on a channel 24 extending in the circumferential direction of the insert 10A, which in FIG a second outlet 22A opens.
- the channels 23, 24 are radial Wall parts 26 separated from each other. Their ends lie on the inner wall of the lower one Part of the mixing cannula 9A, this lower part engaging over the insert 10A.
- the canals 23, 24 are delimited on the outside by the inner wall 25 of the lower part of the mixing cannula 9A.
- Channel 23 opens into output 21A, while channel 24 opens into output 22A.
- the resulting configuration of outputs 21, 21A and 22, 22A is shown in FIG Figure 10.
- the output 22A is offset radially outwards to the output 21A, during the Output 21 A is offset radially outwards to output 22.
- the outputs 21, 21A communicate with the passage opening 17A, while the outputs 22, 22A with the Communicate through opening 18A.
- These outputs 21, 21A and 22, 22A are respectively circular section, the radially outer outlet 21A, 22A occupies a larger angular range than the adjacent output 21, 22.
- the channels 23, 24 and the associated outputs 21A and 22A are each from the inner wall 25 limited.
