Description

[0001]
BACKGROUND OF THE INVENTION
The invention relates to a bayonet fixing device according to the preamble of claim 1 or claim 2 for the correct attachment of accessories to a dispensing device, in particular for the attachment of a mixer to a two-component cartridge.
[0002]
[Prior art]
Having means for attaching the mixer to the cartridge, for example according to U.S. Pat. No. 4,767,026 or U.S. Pat. No. 4,538,920, rotating the two bayonet clamping collars of the mixer to the corresponding cartridge There are a number of mixers and cartridges that insert into the prong. On the other hand, rotational clamping movement of the entire mixer will cause one chemical component to contaminate other chemical components at the interface between the cartridge and the mixer. That is, these components are each carried from one outlet to the other and from one inlet to the other, preferably between these chemical components at the interface between the cartridge and the mixer or closure means. Will result in no reaction, eventually returning such a reaction back into the cartridge outlet, thereby clogging the outlet. On the other hand, for example, when the cartridge outlet or mixer inlet is different in size due to a different relative mixing ratio, or when the mixer or accessory is remounted for reuse, the mixer or accessory It may be necessary to couple and attach the item to the multi-component cartridge or dispenser in a predetermined direction.
[0003]
A clean mixer or accessory inlet area or closure plug can be angled, eg, angularly, with chemical components at the cartridge outlet area during the initial placement of the mixer or closure plug relative to the cartridge in preparation for installation. Thus, another form of cross-contamination can occur when making some form of misaligned contact. In that case, the cartridge outlet can be chemically contaminated when the same mixer or closure plug is fitted in the wrong direction. This can also clog and return the reaction back into the cartridge outlet.
[0004]
[Problems to be solved by the invention]
Based on this prior art, it is an object of the present invention to provide a bayonet attachment means in which the alignment of the accessory inlet with respect to the cartridge outlet is performed only in one fixed direction to avoid cross-contamination.
[0005]
Finally, all prior art bayonet attachment means commonly have a relatively small bayonet tip in the cartridge, thus limiting structural rigidity and strength. This tends to cause deflection and distortion and reduces the diameter of the mixer, thus increasing the back pressure, resulting in a tendency to leak at the mixer / cartridge sealing interface during dispensing. Very important. Accordingly, a further object of the present invention is to improve strength against stress and structural rigidity.
[0006]
[Means for Solving the Problems]
The first object of the invention is achieved with a device according to independent claim 1, and the second object is achieved with a device according to dependent claims 2 to 4. Other objects and improvements of this device are defined in the further dependent claims.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings of embodiments.
1 and 2 show a mixer 1, which is integrated with a mixer housing 2, a mixer element group 3, a mixer outlet 4, and a properly aligned separation element 3S of this mixer element group 3. FIG. There is a mixer inlet 5 with two separate inlet sections 6 and 7.
[0008]
The mixer housing comprises longitudinal ribs 8, which end in the large diameter 9 of the mixer housing 2, whose two lateral ends are made on the bayonet collars 10 and 11, so that the bayonet retaining means of the cartridge Cooperate with. As can be seen from FIG. 2, the two collars are not the same width and the collar 10 is larger than the collar 11. As will be shown later, the different collar widths allow this mixer to be code aligned to the cartridge and only be mounted in a fixed direction.
[0009]
This mixer is attached to the cartridge by rotating the mixer housing 2 while aligning the bayonet collars 10 and 11 having different widths with the bayonet sockets 19 and 20 having different widths and pressing the mixer against the cartridge. The inlet portions 6 and 7 and the mixer element group 3 comprising the separation element 3S do not rotate. In this embodiment, the separation element 3S functions as separation means for separately guiding each chemical component to the first partition element 3D of the mixer element group 3.
[0010]
The cartridge 12 of FIG. 3 has two cylindrical containers 13 that are equal in cross-sectional area for a metering ratio of 1: 1 and end in two separate cylindrically spaced outlets 14 and 15. . The outer shape of the remote outlets 14 and 15 of this cartridge corresponds to the inner shape of each of the separate inlets 6 and 7 of the mixer 1 (see FIG. 1), so that these inlets of the mixer are at the outlet of the cartridge. Fit on top and make a tight seal. A reverse arrangement is also possible in which the inlet portions 6 and 7 fit into the outlet openings 14 and 15.
[0011]
In FIG. 4, the bayonet means 16 attached to the cartridge comprises a ring-shaped bayonet socket 17 with two internal recesses 18 and a circular with bayonet cutouts 19 and 20 of two different diameters facing each other. There is an opening to receive the bayonet collars 10 and 11 (see FIG. 1) of correspondingly different widths of the mixer so that the mixer can be inserted by sign only in one predetermined direction. The flange portions 21 adjacent to these notches act as bayonet holding means for fixing the collar of the mixer.
[0012]
This ring bayonet means increases the strength of the bayonet retaining means and increases the structural rigidity of the outlet end of the cartridge, particularly when the hydraulic pressure transmitted from the installed mixer is maximum during dispensing. This device is a significant improvement over prior art plug tips.
[0013]
FIGS. 5 and 6 show a further embodiment in which the mixer comprises a male inlet portion that fits and seals into the female outlet of the cartridge.
[0014]
FIG. 5 is a view of the inlet end of the mixer 101, which has a mixer housing 102 with a mixer inlet including two separate male inlets 104 and 105, followed by separation means. This mixer is also attached to the cartridge by aligning the mixer cord means with the cartridge cord means, pressing the mixer against the cartridge, and rotating the mixer housing about the integral mixer parts inside. The mixer housing comprises longitudinal ribs, which end in a large diameter 106, whose two lateral ends are made in bayonet collars 107 and 108 and cooperate with the bayonet retaining means of the cartridge. The widths of these two collars are not the same, and the collar 107 is larger.
[0015]
The cartridge 109 (FIG. 6) has two cylindrical containers 110 and 111 with remote outlets 112 and 113 that fit over and seal over the male inlets 104 and 105 of the mixer. The cartridge front surface 114 includes the same bayonet means 16 as the cartridge of FIG. 4 and includes a ring-shaped bayonet socket.
[0016]
Figures 7 and 8 show a further embodiment in which the mixer comprises a male and female inlet portion that fits into and over the female / male outlet of the cartridge.
[0017]
FIG. 7 shows the mixer 115 and has a mixer housing with a mixer inlet that includes an outlet and another male inlet 118 and another female inlet 119. This mixer is also attached to the cartridge by pressing the mixer against the cartridge and rotating the mixer housing 116 around an internal integral mixer part including separate male / female inlets 118 and 119. The mixer housing comprises longitudinal ribs, which end in a large diameter and whose two lateral ends are made in bayonet collars 121 and 122 to cooperate with the bayonet retaining means of the cartridge. The widths of these collars are not the same and the collar 122 is larger.
[0018]
Cartridge 123 was provided with one remote male outlet 126 and one remote female outlet 127 that fit and seal into another female inlet 119 of the mixer and over another male inlet 118, respectively. There are two cylindrical containers 124 and 125. The cartridge front face 128 (FIG. 8) includes the same bayonet means 16 as the cartridge of FIG. 4 and includes a ring-type bayonet socket.
[0019]
FIGS. 9 and 10 show a mixer 25 as a further embodiment, which includes a mixer housing 26, a mixer element group 3, a mixer outlet 4 and a mixer inlet 27. This mixer is fixed to the cartridge 35 (see FIG. 11) with the aid of another coupling ring 31 (see FIGS. 13 and 14). This coupling ring 31 has two bayonet collars 32 and 33 of different widths corresponding to the bayonet notches 19 and 20 of the bayonet mounting means 16 of the cartridge, respectively, and on the cylindrical outer surface for easy gripping by hand. Ribs 34 are provided.
[0020]
In particular, from FIG. 9, this mixer inlet 27 has two cylindrical individual inlet openings 28, 29 on the inlet side of the first mixer element 3S, this first mixer element 3S. In this embodiment, it acts as a separating means for separately guiding each component to the first partition element 3D of the mixer element group 3. The slot 30 allows the mixer to be code aligned with respect to the cartridge.
[0021]
The cartridge 35 (see FIGS. 11 and 12) has a protrusion 36 at the bottom of the bayonet mounting means corresponding to the mixer slot 30 (see FIG. 9) for alignment by the mixer cord. Except for this, it is the same as the cartridge 1 of FIG.
[0022]
When this mixer is coupled to the cartridge, the protruding piece 36 on the cartridge fits into the slot 30 of the mixer inlet 27. This cord connection method not only allows only one alignment, but also allows the mixer to be mounted axially without rotating the mixer housing.
[0023]
Other cord means that can be provided on the dispensing device or cartridge and on the accessory to code the accessory to the dispensing device or cartridge, such as a pin or any type of protrusion that fits into a recess, cavity or slot There are parts.
[0024]
FIG. 15 shows, as a modification of the previous embodiment, a mixer 38 attached to a cartridge 75 having containers 76 and 77 with different cross-sectional areas, and the mixer inlet 37 of the mixer 38 is located in the mixer. There are separation means comprising separate inlet chambers, 39, 40, each having a different cross-sectional area, housed in a smaller overall diameter than the cartridge outlet, with an opening corresponding to each chamber for the material to pass through.
[0025]
The separation means serves to maintain separation of the material flowing to the first partition element 3D of the mixer element group 3. The separating means may have equal chamber cross-sectional areas or a cross-sectional area ratio other than 1: 1. For example, the sectional area ratio of these separation chambers can be the sectional area of the containers 76 and 77 of the cartridge 75 with respect to the metering ratio. This separating means is fixedly coupled to the mixer element group 3.
[0026]
A further embodiment of the present invention according to FIGS. 16-21 includes a clamping ring 51 that snaps onto the cartridge 42 and is permanently attached. The cartridge 42 has two cylindrical containers 43 of equal cross-sectional area, two remote outlets 45 and 46, and mounting means 47 for mounting the clamping ring and limiting its rotational movement. This attachment means 47 has two collars 44 of the same width and is arranged around two remote outlets, in the form of a circular edge with a circular undercut 48 at its base.
[0027]
The clamping ring 51 (see FIGS. 18A, 18B and 19) is snapped onto the circular edge 49 of the mounting means of the cartridge and remains attached to it. The clamping ring 51 has an inner circular groove 52 that forms an edge 53 on the cartridge side and an edge 54 on the mixer side. The cartridge side edge 53 has two opposing notches 55 whose width corresponds to the collar 44 of the cartridge mounting means, the inner diameter of the cartridge side edge 53 being slightly smaller than the outer diameter of the cartridge mounting means. To snap the clamping ring onto the cartridge, place the ring so that the notch on the cartridge side is over the collar of the mounting means, and then press the ring against the cartridge to remove the clamping ring. The remainder of the cartridge side edge is slid into the circular undercut 48 of the mounting means. The clamping ring also includes serrations 58 for easy gripping by hand.
[0028]
On the mixer side edge 54 there are two opposing notches 56 and 57 of different widths corresponding to the collars 10 and 11 of the mixer, so that they can only enter one direction. These two cutouts are arranged at 90 ° with the cutout 55 on the cartridge side edge. Thus, when the mixer 59 is to be attached to the clamping ring on the cartridge, rotating the clamping ring by 90 ° will cause the remaining inner flange portions of both the cartridge side edge and the mixer side edge to become the cartridge mounting means. The 47 collar 44, of course, acts as a bayonet retaining means surrounding the collars 10 and 11 of the mixer and is firmly attached.
[0029]
FIGS. 20 and 21 show the cartridge 42 of FIG. 16 with a mixer 59 that does not allow the housing 60 to rotate around an integral internal part of the mixer and without the ribs 8. Except that the widths of the two bayonet collars 10 and 11 are different, they are similar to the mixer 1 of FIG. 1 and have the same inlet part 5 with separate female inlets 6 and 7. FIG. 20 shows a view in which the mixer is inserted into the clamping ring 51 and the clamping ring is in its clamping position, and FIG. 21 is taken along line XXI-XXI in FIG.
Figure 2 shows a section of the same assembly rotated 90 °. It will be apparent that mixers with separate inlet chambers can be similarly installed and that the cartridge may have containers with different cross-sectional areas.
[0030]
The mixer cording system described above also allows cording of caps, adapters, etc., thereby preventing cross-contamination and allowing cap reuse. The cap attachment used is similar to the mixer attachment and is fitted in a cord fashion to the outlet and attachment of the cartridge.
[0031]
FIGS. 22 to 24 show a further embodiment of the invention with a reverse bayonet device compared to the mixer and cartridge bayonet device according to FIGS. FIG. 22 shows a mixer 80 with a mixer housing 81 with a mixer outlet 4 and a mixer inlet 82 containing the above parts and separating means. This mixer also combines the mixer and cartridge cord means to push the mixer against the cartridge and to connect the mixer housing 81 of this mixer to the separate female inlets 83 and 84, the separation element 3S and the mixer element group 3 Attach to the cartridge by rotating around the internal integral mixer part. This mixer element group or parts thereof may be pre-aligned and fixedly assembled in the mixer housing.
[0032]
The mixer housing 81 is provided with longitudinal ribs 8 ending with a large diameter 85. At the large diameter end of the mixer housing there is a protruding piece 89 that provides a visible code guide for alignment and insertion into the slotted tip 90 of the cartridge. The mixer housing 81 also includes ring-shaped bayonet socket attachment means 100 that includes two bayonet flange portions 94 and 95 that act as bayonet retaining means and have two notches 96 and 97 in between.
[0033]
The cartridge 86 has two cylindrical containers 87 and 88 with remote outlets 14 and 15 for fitting and sealing to the mixer inlet 82. The cartridge front face 86A includes a slotted tip 90 and a guide piece 91 to prevent incorrect insertion of the mixer, and further corresponds to the mixer cutouts 96 and 97 with a small diameter cutout 98 therebetween. There are also two bayonet flanges 92 and 93 with tapered wedge-shaped edges.
[0034]
In order to attach the mixer to the cartridge, when the mixer inlet is pushed over the remote male outlets 14 and 15 of the cartridge, while the portion 91 acts as a guide piece, the protruding piece of the mixer housing By aligning 89 within the slotted tip 90, the mixer inlet 82 is inserted into the cartridge so that the cartridge flanges 92 and 93 are aligned with and enter the mixer notches 96 and 97. As the mixer housing is rotated, the mixer bayonet flanges 94 and 95 are progressively attached to the cartridge flange because the cartridge flanges 92 and 93 are tapered in the depth direction and press the mixer 80 against the cartridge front face 86A. Move against. During attachment of the mixer to the cartridge, the mixer housing 81 rotates 90 ° around a stationary internal integral mixer part.
[0035]
The bayonet device described above, with the ring-shaped bayonet socket on the accessory side as illustrated in the rotary mixer housing, can be used in the embodiments and caps shown above, except for the clamping ring solution. Can be used in a similar way. Placing alternative cord means on the outer periphery of the mixer housing can be achieved or can be accomplished by varying the notch width and engaging flange parts.
[0036]
The embodiment of FIGS. 25-31 shows a fan-shaped bayonet socket rather than a perfect ring. The function and attachment of this accessory is the same as the previous embodiment, so three different embodiments of this bayonet means will be described with one example of each of the mixer and cartridge. It will be apparent that this sector bayonet socket and similar means can be provided in all other embodiments.
[0037]
The mixer housing of the mixer 130 has two lateral ends that are formed as bayonet collars 136 and 137 and cooperate with fan-shaped bayonet sockets 145, 146 that act as bayonet retaining means for the cartridge 138 of FIG. These bayonet collars have the same width, each with ribs 136A and 137A at their ends, which reinforce each collar and act as a stopper, and that the mixer can be mounted rotating in only one direction Guarantee. The top surfaces of these collars may have surface components that are sloped to enhance the ability to tighten due to axial loads. Corresponding inclined surface parts may also be arranged on corresponding surfaces of the cartridge sector bayonet socket.
[0038]
The cartridge 138 of FIG. 25 has two cylindrical containers 139 and 140 with two separate female outlets 141 and 142 for receiving and sealing separate male inlets 133 and 134. The cartridge front surface 143 (FIG. 25) includes bayonet means including fan-shaped bayonet sockets 145, 146 which act as pointed ends and are closed on one side by ribs 145A and 146A, which ribs are the end walls of the cartridge. In combination with this, the tip of the bayonet is cured to increase the strength. Notches 149 and 150 between the sector bayonet sockets allow mixer bayonet collars 136 and 137 to be inserted.
[0039]
In this embodiment, the bayonet collar and the fan-shaped bayonet socket are approximately the same width. The encoding is performed by separate encoding means for the mixer and the cartridge. The cartridge front surface 143 includes a T-shaped protrusion 151 disposed between the two outlets, and the mixer inlet surface includes a similar protrusion 152 disposed off-center between the mixer inlets (see FIGS. 25 and 25). (See FIG. 26).
[0040]
These two T-shaped coding means, when these two protrusions are placed so as to overlap each other, they prevent the mixer inlet from being inserted into the cartridge outlet, and the contact between the cartridge outlet and the mixer inlet or closure means plug This also prevents the mixer from being installed in one direction, thereby preventing cross-contamination and prohibiting mixer / accessory installation. These coded projections can take other shapes besides T-shape and, for example, in the form of a keyway, a mixer can be inserted with a corresponding projection only at one fixed position Obviously, there may be two differently shaped keyways and corresponding protrusions.
[0041]
This cord alignment can be facilitated by marking 153 on the visible cord means, for example, the cartridge outlet end, and marking 154 on the same side as the cord protrusion of the bayonet collar 137 of the mixer.
[0042]
In the embodiment of FIGS. 27-28B, this coding is achieved by notches with different widths between bayonet collars. The mixer housing of the mixer 155 of FIG. 28 (B) has longitudinal ribs ending in a large diameter, the two lateral ends of which are made on the bayonet collars 160 and 161 and cooperate with the fan-shaped bayonet holding means of the cartridge. To do.
[0043]
Each of these bayonet collars 160, 161 can be provided with a rib 167 (FIG. 28A) on the opposite side of the mixer inlet, which prevents the mixer from being attached to the correct alignment and 180 °. Not only can it only rotate in the direction, but it also reinforces the collar and acts as a stopper. The top surfaces of these collars may have components (not shown) that are sloped to enhance clamping and sealing capabilities by axial forces. Corresponding inclined surface parts (not shown) may also be placed on the corresponding surface of the cartridge sector bayonet socket.
[0044]
Cartridge 162 has two cylindrical containers 163 and 164 with two separate female outlets 165 and 166 for receiving and sealing separate male inlets 157 and 158. Cartridge front 168 (FIG. 27) includes bayonet means including two fan-shaped bayonet sockets.
[0045]
In FIG. 27, the bayonet means of the cartridge has two diametrically opposed sectoral bayonet sockets 169 and 170 that act as bayonet tips for the bayonet collar of the mixer, the widths of these two sockets being different, The width is larger. Two notches 171 and 172 between the sockets allow the corresponding mixer bayonet collars 160 and 161 to be inserted into the sector bayonet sockets 169,170. As shown in this figure, the passages of the bayonet sockets 169 and 170 start with straight passages, but the middle point is bent to increase the strength of the bayonet collar against the axial force.
[0046]
These passages have no straight portions and may be entirely bent, or they may be provided on the ring-shaped bayonet mounting means in whole or in part.
[0047]
While the mixer inlet and cartridge outlet are misaligned, the larger one is used to avoid inadvertent contact of one of them in some way with respect to the other. A V-shaped protrusion 192 corresponding to the V-shaped cut 193 of the socket 169 is provided in the large notch 195 of the mixer, and this V-shaped protrusion 192 prevents the mixer from sliding over the narrower socket 170.
[0048]
Again in this embodiment, alignment by code can be facilitated by marking visible code means, such as a mark 153 on the cartridge and a mark 154 on the corresponding collar.
[0049]
If the mixer does not need to be mounted on the cartridge 162 in one fixed orientation, the notches between the collars of the mixer must be large enough to fit into the larger holding means of the cartridge, while visible The coding means remains the same as described above.
[0050]
The mixer 155 has two diameter extensions, for example one is a first part 159 at the inlet that houses and seals the separate inlets 157, 158, followed by separation means 157A, 158A. Is a second portion 159A that houses and seals. The bayonet collars 160, 161 also have ribs and are of the same width, but the gaps or notches 194, 195 between them are different, corresponding to the different widths of the cartridge sector bayonet socket.
[0051]
FIGS. 29 to 31 are devices similar to those of FIGS. 27 to 28B except that the mixer 200 is separate from the coupling ring 196, and the coupling ring bayonet collars 160A, 161A are connected to the cartridge 162. FIG. When the rotary bayonet sockets 169, 170 are rotationally clamped, the coupling ring is rotated around the stationary mixer.
[0052]
FIG. 29 shows the mixer 200 and cartridge 162 when assembled. It has a housing 201 in the mixer 200 that includes a mixer element group 3 aligned with an inlet 197, which inlet is only partially included in the mixer housing, with separate male inlets 157B, 158B and separate It includes that of the other chambers 157C and 158C. A ridge 198 houses and seals the inlet 197 within the mixer housing. The coupling ring 196 is preassembled and is pre-aligned with the mixer inlet 197 via the groove 199 (FIG. 30A) of the coupling ring 196. FIG. 30 (B) shows a coupling with the same coded bayonet collars 160A, 161A, notches 194A, 195A, visible cord 154A and V-shaped projection cord 192A as used in the embodiment according to FIG. 28 (A). A ring 196 is shown.
[0053]
Prior to such assembly, the coupling ring 196 is pre-assembled into the mixer with sufficient tension so that both parts are in visual contact with the initial cord and axial mechanical contact with the initial cord. With the correct relative alignment, the mixer inlets 157B, 158B are attached to the cartridge outlets 165, 166 of this cartridge before the coupling ring is finally rotationally clamped as described above. Thus, in this embodiment, the mixer housing 201 does not rotate around the stationary mixer inlet 197 and element group 3 when installed.
[0054]
In the embodiment according to FIGS. 32 to 34, similar to the embodiment according to FIGS. 22 to 24, the sector bayonet socket is in the mixer and the bayonet collar is in the cartridge.
[0055]
FIG. 32 shows a mixer-cartridge assembly, where the mixer 173 has a mixer housing 174 with an outlet 4 and a mixer inlet 175 that includes an integral part of the interior, which , There are two separate inlets 176 and 177 followed by separate chambers 176A and 177A, which are then fixedly attached to the first partition element 3D of the mixer element group 3. This mixer is also attached to the cartridge by pressing the mixer against the cartridge and rotating the mixer housing 174 around the separate male inlets 176 and 177, the separate chambers 176A and 177A and the mixer element group 3. The mixer element group or parts thereof may also be assembled to be pre-aligned and secured within the mixer housing.
[0056]
In this mixer, at the inlet end of the mixer housing, there are two cylindrical extensions instead of only one, for example, one at the inlet to accommodate and separate the separate inlets 176, 177. A portion 178, followed by an intermediate diameter second portion 178A that houses and seals the separating means 176A, 177A.
[0057]
The mixer housing 174 has longitudinal ribs 8 ending with a large diameter 178, the two lateral ends of which are made into two oppositely shaped sector bayonet sockets 179 and 180 (see FIG. 34) that act as tips. Thus, they are both closed on one side by ribs 179A and 180A, which bond with the mixer wall to harden the bayonet tip and increase strength. Notches 181 and 182 between the sockets allow the insertion of a cartridge bayonet collar that cooperates with the bayonet retaining means of the mixer.
[0058]
33 has two cylindrical containers 184 and 185 with two separate female outlets 186 and 187 that fit over and seal over separate male inlets 176 and 177. The cartridge front surface 188 includes bayonet means including fan bayonet collars 190 and 191 of the same width, each of which includes ribs 190A and 191A at their ends, which attach the mixer to correct alignment and 180 °. In order to prevent this, it can be rotated only in one direction, and of course, it reinforces the collar and acts as a stopper. The top surfaces of these collars may have components (not shown) that are slanted to enhance the clamping capability due to axial loads. Corresponding inclined surface parts (not shown) may also be placed on the corresponding surface of the mixer fan bayonet socket.
[0059]
These collars are almost equal in width, like notches. Thus, the necessary encoding is performed by separate encoding means in the mixer and cartridge. Thus, the cartridge front surface 188 includes a T-shaped protrusion 151 disposed between two remote female outlets, and the mixer inlet surface is a similarly shaped protrusion 152 disposed off-center between the mixer inlets. (See FIG. 33 and FIG. 34).
[0060]
These two T-shaped encoding means, when the mixer is placed on the cartridge so that these two protrusions overlap each other, they prevent the separate male inlet of the mixer from being inserted into the remote female outlet of the cartridge, It also prevents contact between the cartridge outlet and the mixer inlet so that the mixer can only be installed in one location, thereby preventing cross-contamination and prohibiting mixer / accessory installation. Obviously, these coded projections can take other shapes than the T-shape.
[0061]
In some cases, the T-shaped coded protrusion on one side does not provide 100% protection to avoid cross-contamination. FIGS. 35-42 show several coding protrusions that ensure that cross-contamination does not occur if the mixer is inserted into the cartridge in the wrong direction. For this purpose, the coding protrusion is arranged so that it does not tilt around the axis connecting the two outlet centers of the cartridge, which will cause this contamination.
[0062]
Cartridge 210 of FIG. 35 is similar to cartridge 162 of FIG. 27 and has the same two cylindrical containers with two separate female outlets 165 and 166 for receiving and sealing separate male inlets 157 and 158. . The cartridge front surface 211 has two fan-shaped bayonet sockets 169 and 170 that are opposite in diameter to act as bayonet tips for the bayonet collar of the mixer. Two notches 171 and 172 between the sockets allow the corresponding mixer bayonet collars 160 and 161 to be inserted into the sector bayonet sockets 169,170. As shown in FIG. 35, the passages of the bayonet sockets 169 and 170 begin with straight passages. However, the bayonet sockets 169 and 170 are bent from the middle point to increase the strength of the bayonet collar against the axial force.
[0063]
Unlike the cartridge of FIG. 27, the front surface of this cartridge 210 is two pins arranged asymmetrically with respect to the axis connecting the center of the outlet but asymmetrically with respect to the transverse intermediate axis, for example on one outlet side. The encoding means 212 which consists of 213 is provided.
[0064]
FIG. 36 is a view of the inlet end of a mixer 214 comprising a mixer housing containing two separate inlets 157 and 158 followed by separation means. The mixer is also attached to the cartridge by pressing the mixer against the cartridge and rotating the mixer housing around the integral mixer part inside. The mixer housing has longitudinal ribs ending in large diameter, the two lateral ends of which are made in bayonet collars 160 and 161 to cooperate with the fan-shaped bayonet retaining means of the cartridge.
