AI Technical Summary

Problems solved by technology

Conventional bayonet locks cannot exert traction while the threaded coupling ring provides relatively large travel to remove the stop upwards
So, for larger bayonets with larger stops, this problem has not been solved so far

Embodiment Construction

[0015] 1 and 2 show the outlet end of a double cartridge 1 comprising two storage containers 2 and 3 , separate outlets 4 and 5 , a locking ring 6 and a stop 7 .

[0016] The invention is primarily concerned with the upward removal of the stop 7 from the barrel by a rotation of the locking ring, here counterclockwise. The stop 7 comprises two plugs 8 and 9, a fastening flange 10 and a subsequent neck 11 provided with a traction flange 12 having a groove 13 for A traction disc 14 having a recess 15 is accommodated.

[0017] An outlet flange 16 with two opposing flange ridges 17 and 18 is provided at the end regions of the two outlets 4 and 5 . Each flange ridge comprises a fastening ramp 17A on its underside 19 and a traction ramp 18A on its upper side 20 , said ramps being inclined as viewed in the axial direction. The fastening ramp 17A and the pulling ramp 18A on the outlet flange of the barrel cooperate with the fastening and pulling flanges in the locking ring.

Abstract

The invention relates to a dispensing device, for example, a double cartridge (1), comprising a sealing plug and a locking ring with bayonet connecting means. The sealing plug (7), the outer surfaces of the cartridge outlets (4, 5) and the wall interior of the locking ring (6) comprise means (17, 26; 18, 27), which cooperate with one another, in order to, when turning the locking ring, press the sealing plug into the outlets or pull it out therefrom. This makes it possible to realize a tight closure on the one hand, and on the other, it is very easy to pull the tight-fitting sealing plug out again.

Description

technical field [0001] The invention relates to a dispensing device according to the preamble of claim 1 comprising a stop and a locking ring with bayonet coupling. Such dispensing devices - more particularly multi-component cartridges - are known, for example, from US-A-5 918 772 to the applicant of the present invention. The advantage of bayonet connections over threaded connections is that they allow quick connection and disconnection. On the other hand, bayonet couplings also have disadvantages, especially in the case of larger cartridges requiring greater forces. This problem concerns not only the connection of the mixer or accessories, but also the extraction of the stop whose plug is slightly tapered due to the required tightness, whereby the stop is firmly in place. Background technique [0002] A stop for cartridges is known from US-A-5 137 182 to the applicant of the present invention, in which the upper side of the bayonet cam (cam) can be wedge-shaped for bette...
