The mixer housing 81 rotates 90 ° around a stationary inner integral mixer part.

The bayonet device described above, in which the ring-shaped bayonet socket is on the accessory side, as shown in the rotary mixer housing, except for the clamping ring solution,
A similar method can be used for the embodiment shown above and for the cap. Placing the alternative cord means on the outer periphery of the mixer housing can be accomplished by varying the width of the notches or the flange parts that engage.

The embodiment of FIGS. 25-31 illustrates a fan-shaped bayonet socket rather than a full ring. The function and installation of this accessory is the same as in the previous embodiment, so three different embodiments of this bayonet means will be described with one example for each mixer and cartridge. Obviously, this fan-shaped bayonet socket and similar means can also be provided in all other embodiments.

The mixer housing of the mixer 130 has two lateral ends, which are bayonet collars 136 and 1.

Mixer inlets 157B, 158B are attached to the cartridge outlets 165, 166 of this cartridge for final assembly prior to final rotational tightening of the coupling ring. Therefore, in this embodiment, the mixer housing 201 does not rotate around the stationary mixer inlet 197 and the element group 3 when installed.

In the embodiment according to FIGS. 32 to 34, FIG.
Similar to the embodiment according to FIGS. 2 to 24, the fan-shaped bayonet socket is in the mixer and the bayonet collar is in the cartridge.

FIG. 32 shows a mixer-cartridge assembly in which the mixer 173 has a mixer housing 174 with an outlet 4 and a mixer inlet 175, the inlet of which is an integral part of the interior. Including two separate inlets 176 and 177 followed by separate chambers 176A and 177A, which chambers are then fixedly attached to the first partition element 3D of the mixer element group 3. There is. This mixer also pushes the mixer onto the cartridge,
Mixer housing 174 has separate male inlets 176 and 1
77, mounted in cartridge by rotating around separate chambers 176A and 177A and mixer element group 3. The mixer element group or parts thereof may also be pre-aligned and assembled for fixation within the mixer housing.

In this mixer, at the inlet end of the mixer housing, there are not only one but two cylindrical extensions, for example one at the inlet, containing separate inlets 176, 177 and sealed. A second portion 178A of intermediate diameter for receiving and sealing the separating means 176A, 177A.

The mixer housing 174 comprises longitudinal ribs 8 terminating in a large diameter 178, the two lateral ends of which are provided with two diametrically opposed fan-shaped bayonet sockets 179 and 180 (see FIG. 34) which act as tips. As they are made, they are closed on one side by ribs 179A and 180A, which combine with the mixer wall to harden and strengthen the bayonet tip. The notches 181 and 182 between the sockets allow the insertion of a cartridge bayonet collar which cooperates with the bayonet retaining means of the mixer.

The cartridge 183 of FIG. 33 has two cylindrical containers 184 and 185 with two separate female outlets 186 and 187 that fit over and seal on separate male inlets 176 and 177. The cartridge front surface 188 comprises bayonet means including fan bayonet collars 190 and 191 of equal width, these collars comprising:
Of course, ribs 190A and 191A are provided at each end of the ribs to reinforce the collar and act as a stop, as well as allowing it to rotate in only one direction to prevent proper alignment and 180 ° mounting of the mixer. The upper surfaces of these collars may have beveled parts (not shown) to enhance the clamping capacity by axial loading. Corresponding beveled surface components (not shown) may also be placed on corresponding faces of the mixer fan bayonet socket.

Like the notches, these collars are approximately equal in width. Thus, the necessary coding is done in the mixer and cartridge by separate coding means.

FIGS. 39 and 40 show a coded projection 212 on the front of the cartridge consisting of a male plug 221 and a female receptacle 222 located in the subject. The male plug 223 and female receptacle 224 at the mixer inlet are arranged according to that of the cartridge, and insertion and mounting of the mixer into the cartridge is only possible in one direction.

41 and 42 consist of a rod 225 on one side of the axis connecting the centers of the outlets and two spaced rods 226 on the other side of this axis, symmetrically arranged with respect to the transverse intermediate axis of the cartridge. Also shown is a particularly effective coding projection 212 on the front surface of the cartridge. Single rod 22 at the mixer inlet
7 and double rod 228 are arranged according to that of the cartridge, and the mixer is inserted and mounted in the cartridge,
Only possible in one direction.

All of these coded projections can be of any other suitable shape and form, effectively preventing tilting when the mixer is installed in the cartridge, even if the mixer is oriented in the wrong direction. , Thus preventing cross-contamination.

This cord alignment can be facilitated by marking 153 on the visible coding means, eg, the cartridge, opposite the protrusions, and marking 154 near the cord protrusions on the collar of the mixer. .

From the embodiment of FIGS. 7 and 8, the inlet of the mixer and the outlet of the cartridge can be female or male, respectively, and the mixer can be placed over the corresponding male / female outlet of the cartridge / It also means that it is possible to provide one female entrance and one male entrance to fit inside.

This latter arrangement comprises additional coding means as the mixer or closure means can only be associated with the cartridge in one position. This mixed arrangement of cords and cord means is independent of the attachment method by means of a coupling ring, a clamping ring or a rotatable mixer housing.

Although varying the width of the bayonet collar provides a clear code means, it may be advantageous to enhance this effect by making the code visible. This visualizing can be done, for example, by optical means such as different colors, notches and markings, or by providing a protrusion in the notch of the accessory and providing a notch corresponding to the bayonet holding means of the cartridge. To do. This can be done by visibly marking one of the code parts or by doing it on the code itself.

Cartridges separated by a single wall, eg, according to US Pat. No. 5,333,760, cannot eliminate chemical migration through such single wall separation barrier layers, and thus at the cartridge outlet. Is not sufficient to prevent migration and therefore reaction in the cylinder during storage.

In particular, from FIGS. 16 and 22 it is advantageous to provide an integral cartridge consisting of two complete, preferably cylindrical, containers substantially separated by an air gap L therebetween. (See FIG. 16). This guarantees a complete chemical separation from the front of the cylinder piston up to the outlet where the closing means is fitted during storage, over the entire length of the chemical product. During distribution, this separation is further maintained in the mixer up to the first partition element 3D of the mixer element group.

However, the invention is not limited to containers separated by air gaps, but applies equally to cartridges with containers separated by a single wall according to FIG.

From the above description, this combination of the inventive cartridge and accessory coupling device is especially useful for cartridge containers separated by air gaps to individual outlets, and for mouths of the same or different size. Maintains sufficient separation of chemicals through the interface into the mixer for code matching, and prevents spread of chemical reactions and clogging that can retrograde at this interface and to the cartridge outlet. However, avoid cross-contamination due to rotation or random mounting. This combination also optimizes mixing performance, especially, but not exclusively, for ratios other than 1: 1.

Although the foregoing description and drawings of these cartridge embodiments relate to multi-component cartridges with side-by-side containers, the teachings of this invention are not so limited and may be arranged in concentric containers or otherwise. The same applies to a cartridge provided with a formed container.

However, the principle of mounting with this cord is that the mixer or accessories can only be in one direction,
It ensures both proper alignment and coupling of the mixer or accessory to the cartridge outlet and elimination of cross contamination when the mixer or cap is recoupled to the cartridge.

Moreover, with respect to the mixer, the mixer inlet,
Since the separating means and the mixer element group are made integrally,
The examples described above all include a minimum number of parts,
It has the advantage of being compact and consequently low in molding and assembly costs. Also, the integral construction of this internal component ensures proper alignment and thus optimizes mixing efficiency.

In the case of the first exemplary embodiment according to FIG. 1, if a relatively long mixer element group is used and the rotational friction between this mixer element group and the mixer housing can cause problems, the mixer is Some or all of the element groups are separated from the inlet isolation means and some or all of the mixer element groups are fixed in the housing for proper assembly and thus the mixer is coupled to the cartridge. However, it may be preferable for it to rotate with the housing.

In this case, looking from the mixer inlet to the mixer outlet, the front end of the first element of the mixer element group, or part thereof, must be fixed and assembled in a pre-aligned position in the housing. I won't. Thus, after rotating the housing to attach the mixer to the cartridge, the correct alignment of these elements is obtained and the two material streams leaving the separating means or the first group of elements attached to this separating means are Divided evenly by the front end of this first group of elements attached to this element group or housing,
Optimal mixing efficiency is obtained.

Obviously, instead of cylindrical inlets and outlets, D-shaped or irregularly shaped inlets and outlets of similar or different sizes are possible. Furthermore, the same principle is
It can also be used as a dispensing device for more than components, or as a cartridge.
