As shown in figure 1D, the outlet port 116 is configured to receive a distal end of the corresponding flow channel 132 or a coupling 5 (not shown), such as a tip, needle, nozzle, zircon, or other such connector, that connects or couples the distal end of the corresponding flow channel 132 inside the cartridge 115. In one embodiment, the orifice Exit 116 is a perpetual septc.
    Each cartridge 115, 215 has an exhaust fan 113 (see figures ID, 10 1F, 1G, 1.H) that is configured for entry of atmospheric air into the cartridge
    115, 215 as the fluid is removed by the dispensing pump 150, 250. Exhaust 113 substantially eliminates the vacuum build-up in cartridge 115, 215. Exhaust 113 is configured to substantially prevent fluid leakage from cartridge 115, 215 15 Optionally, the hood 113 is positioned inside the closure device 118, 218 or the outlet hole 116, 216 or is integral with them. For example, the hood 113 is an elastomeric duck nozzle valve, a flapper valve, an umbrella valve, a diaphragm, etc. In. in another example, the hood 113 is a spring loaded assembly such as a ball or ball plunger that engages a sealing opening.
    Optionally, as shown in figure II, a bladder 193 is positioned inside the cartridge 115 and is configured to contain the fluid. The outlet port 116 communicates with the interior of the bladder 193. In embodiments, the bladder 193 is at least one of flexible, removable, replaceable and refillable.
    Optionally, as shown in figure 1 D, a conduit 119, such as a siphon tube, is included with each cartridge 115 »Conduit 119 is configured to draw fluid from inside the cartridge 115 and communicate with the distal end of the flow channel corresponding 132.
    As shown in figures 1 and 2, a flow channel 132, 232 communicates with the interior of a corresponding cartridge 115 »215 both directly and by means of. coupling connection (not shown). Each flow channel 132, 232 carries the fluid from the corresponding cartridge 5, 115, 215 to the mixing chamber 137, 237 of the collector 130, 230 when the dispensing pump assembly 150, 250 is protruding. Each flow channel 132, 232 has proximal and distal ends, a central geometric axis, and a lumen that has a cross section. In one embodiment, the outlet port 116, 216 of the cartridge 115, 215 receives a distal end of the corresponding flow channel 132, 232 ·. In another embodiment, outlet port 116, 216 receives a distal end of the coupling which is connected to the distal end of the corresponding flow channel 132, 232.
    As shown in figures 1, 2 and 5-11, the proximal end 15 of each flow channel 132, 232 is in communication with. one of the inlets 139, 239 of the collector 130, 230.

    As shown in figures' 1, 2 and 8-11, in one embodiment, an adjustable valve assembly 140, 240 is positioned to communicate with a corresponding flow channel 1.32, 232. Each adjustable valve assembly 140, 240 can be controlled independently of other adjustable valve sets 140, 240 in device 100, 200. Each adjustable valve set 1.40, 240 can function independently of other adjustable valve sets in device, adjustable valve set 140, 240 adjusts a mass flow of fluid which is drawn by the dispensing pump assembly .150 »250 from the corresponding cartridge 115, 215 through flow channel 132, 232 each time the dispensing pump assembly 150, 250 protrudes. Each set of adjustable valve 140, 240 has. a mobile control 142, 242 that is configured for use by a user to adjust the adjustable valve assembly 140, 240 in a position that adjusts the mass flow rate of fluid from a corresponding cartridge 115, 215 through the adjacent flow channel 132, 232 when the device 100, 200 is in operation, the mobile control 142, 242, for example, is a rotary knob or screw (figures 1, 2, 8). a sliding key (figure 9), or a lever arm (figure 10). This list should not be interpreted evenly, however, and the mobile control 142, 242 can be anything 10 known to those skilled in the art that is functional on the device.
    Optionally, mobile control 142, 242 has a ruler or other indicator (not shown) that indicates the position of an adjustable valve set 140, 240 with respect to the other adjustable valve sets, or mobile control 142, 242 has incremental markings (not shown) showing the relative proportion of each fluid in each cartridge 115, 215 mixed to form the mixture.
    In an embodiment illustrated in figures 8-10, the adjustable valve assembly 140 is positioned adjacent to the corresponding flow channel 132 and is adjustable along a geometry axis that is not parallel to the central geometry axis of the corresponding flow channel 132 in the point along the flow channel at which the adjustable valve 140 is adjacent to it. Adjustable valve assembly 140 can be configured to progressively decrease the flow rate. mass of fluid extracted from the corresponding cartridge 115 when the device is in use, progressively restricting the cross sectional area of the corresponding flow channel 132, progressively moving the mobile control 142 to a position (s) that make that the adjustable valve 140 is progressively in contact with. an outer surface of the flow channel 132. thereby restricting the cross sectional area of the lumen of the flow channel 132 to decrease the mass flow of fluid moving through it. On the contrary, the mass flow of fluid that is extracted from the cartridge 115, when the pump 150 is operational, is progressively increased by progressively moving the mobile control 142 to a position (s) that causes the adjustable valve to retract progressively by compressing an outer surface of the flow channel 132, thereby causing the lumen of the flow channel 132 to protrude and restore the cross-sectional area of the lumen to increase the mass flow of fluid moving through it. Examples of such an embodiment are illustrated in figures 8-10, which illustrate a diaphragm valve (figure 8), a roller valve (figure 9), and a lever valve (figure 10). These examples are not intended to be limiting or inclusive, however, and any valve known to those skilled in the art is within the scope of this description.
    Figure 8 shows a partial cross-sectional view of one.
    device made through the adjustable valve assembly 140 in which the adjustable valve assembly 140 is a screw-actuated diaphragm valve. The diaphragm valve 140 has a clamp 143 and a threaded shaft 144. The threaded shaft 144 has a tip 145, A control knob 142 matches the threaded shaft 144 in such a way that the progressive axial rotation of the control knob 142 has made with that the threaded shaft 144 moves progressively axially in favor and against the clamp 143, to a closed position (figure 8B) or an open position (figure 8A), respectively. In operation, the portion of the flow channel 132 between the cartridge 115 and the inlets 25 139 of the collector body 138 is restricted by turning the control knob 142 in a first direction to cause the threaded shaft 144 to move towards the clamp 143 until the clamp engages and at least partially compresses the flow channel 132 to restrict the cross-sectional area of the lumen of the flow channel 132 to decrease the mass flow of fluid through flow channel 132. Figure SB illustrates the flow valve diaphragm 140 in the fully closed position. The fluid connection is restored by turning the control knob 142 in a second direction to cause the threaded shaft 144 to move out of the flow channel and decompress it 132 to 5 to cause the lumen of the flow channel 132 to pop out, thereby restoring at least partially the cross-sectional area of the lumen and increasing the mass flow of fluid through the flow channel 132. Figure 8A illustrates the diaphragm valve 140 in the fully open position.
    Referring to figure 9, a .100 device is illustrated in which the adjustable valve assembly 140 is a slide actuated diaphragm valve. Diaphragm valve 140 has a ramp 148 and a roller 149.
