However, those skilled in the art will appreciate that in different embodiments, different combinations of different materials may remain within the tank.

9 and 10 also show other components of trigger 106 . Specifically, the trigger 106 may include a first trigger arm 148 received substantially within the handle 105 and a second trigger arm 150 received substantially within the rear handle arm 114 . The first trigger arm 148 and the second trigger arm 150 may meet at a pivot portion 152 which may include a pivot aperture 154 for receiving a pivot fastener 156 . Pivot fastener 156 may be any type of fastener that is suitable for securing the trigger to housing 102 through pivot aperture 154 and allows trigger 106 to pivot about pivot fastener 156 around pivot portion 152 change. In some embodiments, pivot fastener 156 may be integral with housing 102 of decontamination device 100 . The trigger 106 may also include a trigger input 158 disposed at the distal end 149 of the first trigger arm 148 and a trigger output 160 disposed at the distal end of the second trigger arm 150 . Trigger input 158 may extend from handle 105 into handle gap 116 so as to be accessible to a user holding decontamination device 100 . When a user depresses trigger input 158 , trigger 106 may pivot about pivot fastener 156 , thereby converting the generally vertical movement of the trigger into generally horizontal or lateral movement of trigger output 160 .

While the embodiment shown in FIGS. 9 and 10 includes a pivoting trigger, other contemplated embodiments may include a linkage acting as a cam or a cable and pulley system, which itself may take the form of a variety of configurations. Additionally, the effect of the trigger on the injection duration may vary in different embodiments or combinations of different embodiments. For example, in some embodiments, decontamination device 100 may be configured to mix and dispense material only when trigger 106 is actively depressed, and to cease dispensing when the user releases the trigger. In other embodiments, the decontamination device 100 may be configured to begin mixing and dispensing when the trigger 106 is activated, and to continue mixing and dispensing until the canister is emptied regardless of whether the trigger remains depressed. In other embodiments, the trigger 106 may include a shot lock that may lock the trigger in the depressed position.

In some embodiments, the top portion 109 of the body portion 108 may additionally house a cam member 162 that may engage the mixing manifold 146 . The cam member 162 may have a trigger end 164 and a spring end 166 opposite the trigger end. Cam member 162 may move along first axis 210 , which in some embodiments may be substantially horizontal or transverse relative to mixing manifold 146 between trigger output 160 and nozzle portion 110 . In some embodiments, spring 168 may engage cam member 162 to bias the cam member away from nozzle portion 110 and toward trigger output 160 . In some embodiments, and as shown in FIG. 15 , the spring end 166 of the cam member 162 may concentrically surround the member stem 169 of the cam member. Spring 168 may bear against biasing rod 159 , which may be anchored to housing 102 . Thus, when a user depresses trigger input 158, trigger output 160 may move substantially along first axis 210, which in some embodiments Can be basically horizontal. If trigger input 158 is depressed with sufficient force to overcome the biasing force of spring 168 , cam member 162 may move relative to mixing manifold 146 in a direction toward nozzle portion 110 . Additionally, in some embodiments, the trigger may be configured in a palm squeeze configuration, where, for example, the palm of a user may press the trigger to activate the mechanism that activates the canister. In another embodiment, the trigger may be a thumb press configuration that utilizes an internal mechanism to activate the canister.

11-13 illustrate enlarged views of embodiments of the handle portion 104 and top portion 109 of the body portion 108 with portions of the housing 102 removed for clarity. Referring first to FIG. 13 , the cam member 162 and the mixing manifold 146 can be oriented relative to each other such that at least one camming surface can translate movement of the cam member along a first axis 210 into movement of the mixing manifold along a second axis 215, which The second axis may be substantially perpendicular to the first axis in some but not all embodiments. In some embodiments, first axis 210 may be a substantially horizontal axis and second axis 215 may be a substantially vertical axis. In such embodiments, substantially horizontal movement of the cam member may be translated into substantially vertical movement of the mixing manifold. Specifically, in some embodiments, cam member 162 may have a first cam surface 170, a second cam surface 172, and a third cam surface 174, and mixing manifold 146 may have a first follower 171, a second follower A member 173 and a third follower 175 engage with the first cam surface, the second cam surface and the third cam surface, respectively. When the trigger output 160 pushes the cam member 162 towards the nozzle portion 110, the first cam surface 170, the second cam surface 172, the third cam surface 174 may abut the first follower 171, the second follower 173 respectively And the third follower 175 slides. Since the mixing manifold 146 is substantially limited or restricted in horizontal movement, movement of the cam surface against the follower of the mixing manifold exerts a vertical downward force on the mixing manifold. As a result, the mixing manifold 146 can be moved vertically downward toward the first tank 140, the second tank 142, the third tank 144 from the passive position to the dispensing position. The cam and follower relationship between cam member 162 and mixing manifold 146 is also shown in section in FIG. 14 . Although the embodiment shown here shows three corresponding cam surfaces and followers, embodiments of the cam member and mixing manifold have more or fewer corresponding cam surfaces and followers. In some embodiments, the number of cam surfaces and corresponding followers may correspond to the number of canisters used in a particular device. For example, a device housing two canisters may include a cam member with two cams and a mixing manifold with two corresponding followers. Additionally, in some embodiments, the cam member may be integrated into the trigger itself.

In some embodiments, vertical downward movement of mixing manifold 146 may open first valve 176, second valve 178, and third valve 180 between first tank 140, second tank 142, and third tank 144, respectively. each, releasing the contents of the tank into the mix manifold. First tank 140, second tank 142, third tank 144, their respective first valve 176, second valve 178, third valve 180 and mixing manifold 146 are best shown in FIG. interaction. Figure 14 shows a cross-sectional view of one embodiment of the decontamination device 100, focusing on the top portion 109, and the interaction of the valves, tank and mixing manifold. The embodiment shown in FIG. 14 includes different types of valves for the first valve 176 , the second valve 178 and the third valve 180 . In this embodiment, each of the first valve 176, the second valve 178, and the third valve 180 may include a direct connection to the mixing manifold 146 with integrated nozzles in the manifold. However, it is contemplated that other types of connections may be used in other embodiments. For example, the connection between the first tank 140, the second tank 142, the third tank 144, and the mixing manifold 146 can include a male nozzle on the top of the tank that can be pressed into a gland on the mixing manifold. or contact seal, or the male nozzle may be pressed into a receiving cone on the mixing manifold, or other connections known to those skilled in the art.

In the embodiment of FIG. 14 , mixing manifold 146 may be substantially hollow such that mixing chamber 182 is formed within the mixing manifold. Mixing chamber 182 may extend substantially the entire length of mixing manifold 146 from nozzle portion 110 to a chamber cover 184 that seals the mixing chamber opposite the nozzle portion. Additionally, a chamber insert 186 may be disposed within the mixing chamber 182 to be substantially surrounded by the mixing manifold 146 . The size and shape of chamber insert 186 may affect the volume and flow patterns within mixing chamber 182 . For example, a larger chamber insert may result in a smaller mixing chamber volume, and a smaller chamber insert may result in a larger mixing chamber volume. The size and shape of the mixing chamber 182 may affect the flow pattern and mixing quality of the various materials of the first tank 140 , the second tank 142 , and the third tank 144 as they flow through the mixing chamber and ultimately out of the nozzle portion 110 .

In the embodiment shown in FIG. 14, each of the first valve 176, the second valve 178 and the third valve 180 has a stem portion and a valve hole formed through the stem portion so that when the valve is in the open position, the Fluid communication between each respective first tank 140 , second tank 142 , third tank 144 and mixing chamber 182 is provided. Specifically, when the trigger 106 is activated, the trigger output 160 is caused to move the cam member 162 horizontally and place the first cam surface 170, the second cam surface 172, the third cam surface 174 against the first follower 171 , the second follower 173 , the third follower 175 , and the mixing manifold 146 is pressed vertically downward. The downward vertical movement of the mixing manifold 146 causes the valve stem portion to move downward, simultaneously moving the first valve 176, the second valve 178, and the third valve 180 to open positions. When all the first valve 176, the second valve 178, the third valve 180 are moved to the open position simultaneously, the contents of the first tank 140, the second tank 142, the third tank 144 can enter the mixing chamber 182 substantially simultaneously to Mixing is allowed.

A first tank 140, a second tank 142 and a third tank 144 may be disposed within the housing 102 of the decontamination device 100 and arranged such that upper portions of the tanks may engage respective valves. Specifically, the upper portion 151 of the first canister 140 can be configured to engage the first valve 176, the upper portion of the second canister 142 can be configured to engage the second valve 178, and the third canister 144 can be configured to engage the third canister 144.

The first valve 176 can have a first stem portion 188 with a first valve aperture 189 formed therethrough, the first valve aperture 189 can provide a connection between the first canister 140 and the mixing chamber 182. fluid communication between them. The second valve 178 can have a second stem portion 190 with a second valve hole 191 formed through the second stem portion, the second valve hole 191 can provide a gap between the second tank 142 and the mixing chamber 182. of fluid communication. The third valve 180 may have a third stem portion 192 with a third valve hole 193 formed therethrough, the third valve hole 193 may provide a connection between the third tank 144 and the mixing chamber 182. fluid communication between them. In some embodiments, the upper portion 151 , 153 , 155 of each respective first tank 140 , second tank 142 , third tank 144 may form a valve aperture 194 , 195 , 196 or other inlet to receive or otherwise Each respective first valve 176 , second valve 178 , third valve 180 is engaged.

The size of each valve hole can vary between valves and depends on the desired mixture quality. For example, in the embodiment shown in FIG. 14 , the first valve aperture 189 formed through the first stem portion 188 may be relatively narrow compared to the second valve aperture 191 formed through the second stem portion 190 . This relationship may be desirable where the mixture dispensed by the decontamination device 100 has a higher volume of material stored in the second tank 142 compared to the material stored in the first tank 140 . As a further example, the third valve 180 shown in FIG. 14 may include a restrictor orifice, as the third valve bore 193 formed through the third stem portion 192 narrows near the mixing chamber 182 . However, it should be understood that any of these types of orifices, and others, may be used in any combination to affect the mixture dispensed from the decontamination device 100 . It should also be understood that other types of device components may be used to control the proportion of material entering the mixing chamber 182 from the tank and the amount of material exiting the final nozzle 120 . For example, other embodiments may include induced vortices, pressure-regulated orifices, resistance orifices, and the like. The components and features described herein can increase control over the proportions of mixed materials on a mass or volume basis, since in some embodiments, the dispensed materials can depend on tightly controlled mix percentages.

FIG. 14 also shows the relationship between mixing manifold 146 , chamber insert 186 and nozzle face 125 . Nozzle end 197 of chamber insert 186 and nozzle end 198 of mixing manifold 146 may engage nozzle face 125 to form a flow path between mixing chamber 182 and final nozzle 120 . Nozzle face 125 may include a generally cylindrical outer nozzle collar 121 that may receive nozzle end 198 of mixing manifold 146 . Nozzle face 125 may also include an inner nozzle collar 123 substantially concentric with outer nozzle collar 121 that may receive nozzle end 197 of chamber insert 186 . In the embodiment shown in FIG. 14 , mixing space 129 may be formed within outer nozzle collar 121 and nozzle end 198 of mixing manifold 146 which may be in fluid communication with mixing chamber 182 . Additionally, while the inner nozzle collar 123 may substantially surround the nozzle end 197 of the chamber insert 186 , it should be understood that at least a portion of the inner nozzle collar may allow fluid communication between the mixing space 129 and the final nozzle 120 . However, in some embodiments, the engagement between the nozzle end 197 of the chamber insert 186 and the inner nozzle collar 123 may at least somewhat restrict flow between the mixing space 129 and the final nozzle 120 . In some embodiments, such confinement may allow improved flow of materials released from first tank 140, second tank 142, third tank 144 to occur within mixing space 129 as they flow through mixing chamber 182 and converge in mixing space 129. the mix of. In other words, in some embodiments, material released from the canister closest to the nozzle portion 110 (e.g., third canister 144) may be released from a canister further away from the nozzle portion (e.g., first canister 140 or second canister 142). Before the released material reaches the mixing space 129, the restrictive engagement between the nozzle end 197 of the chamber insert 186 and the inner nozzle collar 123 of the nozzle face 125 can slow down the dispersion of the material, thereby allowing Opportunity for more thorough mixing. Another view of the relationship between mixing manifold 146 , chamber insert 186 and nozzle face 125 is also shown in FIG. 15 with pull safety device 118 positioned above nozzle face 125 .

Thus, in the embodiment shown in FIGS. 14 and 15, when the user activates the trigger 106, the material stored in the respective first tank 140, second tank 142, third tank 144 can be released into the In the mixing chamber 182 , flows into the mixing space 129 and exits as a mixture through the final nozzle 120 .

16 and 17 illustrate the relationship between pull safety device 118 and trigger 106 . In some embodiments, pulling the safety device 118 prevents actuation of the trigger 106 while in place. Specifically, the tail 126 of the pull safety device 118 can include a tail tip 132 that can fit through the tip aperture 130 formed in the front handle arm 112 to engage the distal end 149 of the first trigger arm 148 . In some embodiments, a safety hole 147 may be formed in the distal end 149 of the first trigger arm 148 to receive the tail tip 132 . In such an embodiment, the tail tip 132 may prevent the first trigger arm 148 from moving when the user applies pressure to the trigger input 158 . This safety mechanism prevents accidental or inadvertent activation and dispensing of materials stored within decontamination device 100 . However, when the user desires to use the decontamination device 100 , the user can remove the pull safety device 118 , for example, via pulling the pull tab 122 . Pulling the tab 122 removes the center cap 124 from its position over the nozzle face 125 and further removes the tail tip 132 from the safety hole 147 in the trigger. This embodiment of the pull safety device 118 and trigger 106 can help prevent improper activation of the device because the pull safety device can be configured so that the tail tip 132 cannot be removed from the safety hole 147 and the tip aperture 130 until the central The cap 124 has been pulled away from the final nozzle 120 . However, in other embodiments, it is contemplated that the tail tip 132 and central cap 124 may be removed separately.

In some embodiments, as best shown in FIG. 17 , tail tip 132 can include at least one finger 133 and each finger 133 can also include a finger-like protrusion 135 . In such an embodiment, safety hole 147 may be formed relatively wider near its end than at its entrance to accommodate finger-like protrusion 135 when tail tip 132 is seated within the safety hole. A gap may be formed between the fingers 133 so that when the tail tip 132 is removed from the safety hole, the sloped wall of the safety hole 147 bears against the finger protrusion 135, forcing the distal end of the finger 133 inwardly. Such inward movement of the fingers 133 may allow the tail tip 132 to be removed from the safety hole 147 when the user pulls with sufficient force to overcome the tendency of the fingers to resist inward movement. In some embodiments, once the tail tip 132 is fully disengaged from the safety hole 147, the elasticity of the fingers 133 can force the distal end back to the original expanded position. In such an embodiment, fingers 133 may expand to a width greater than the width of the entrance to safety hole 147, thereby preventing or limiting the ability to reinsert tail tip 132 into the safety hole. In such an embodiment, a potential user of the decontamination device 100 may know that the device may not be complete because the pull safety device 118 has been previously removed. In some embodiments, fingers 133 may not spring back into place, but instead become permanently deformed when removed from safety aperture 147 . In such an embodiment, the tail tip 132 may be rendered insecure within the safety hole 147 because the fingers 135 would not abut outwardly against the walls of the safety hole. Thus, in such an embodiment, a potential user may also be alerted to the fact that the pull safety device 118 has been previously removed and the canister may be full.

Figure 18 shows the decontamination device 100 in a dispensing position in which the trigger 106 has been moved from the passive position (eg, Figure 13) to the dispensing position. As shown, the trigger output 160 can abut the trigger end 164 of the cam member 162 to move the cam member horizontally from the passive position toward the nozzle portion 110 to the dispensing position. When the cam member 162 moves toward the nozzle, the first cam surface 170, the second cam surface 172, and the third cam surface 174 can press down the first follower 171, the second follower 173, and the third follower, respectively. 175, which may move the mixing manifold towards the first tank 140, second tank 142, third tank 144 from the passive position to the dispensing position. Downward movement of the mixing manifold 146 can open the first valve 176, the second valve 178 and the third valve 180, thereby allowing the material in the respective first tank 140, second tank 142, third tank 144 to enter the mixing manifold , mix and dispense through nozzles.

19 and 20 illustrate an alternative embodiment of a pull safety device 218 having a tail tip 232 that can be used with a trigger 206 that forms a safety hole 247 at its distal end 249 . In this embodiment, the tail tip 232 may include a first finger 233 and a second finger 234 with a gap 235 formed between the two fingers. Safety hole 247 may be formed relatively wider near its end than at its entrance to accommodate first finger 233 and second finger 234 when tail tip 232 is in place within the safety hole. At least one of the first finger 233 or the second finger 234 may include a finger cam 236 . In some embodiments, when the tail tip 232 is pulled out of the safety hole 247, the pressure of the wall of the safety hole on the finger cam 236 can force the second finger 234 towards the first finger 233, thereby causing the user's finger to 233. Gap 235 narrows when pulled with sufficient force to overcome the tendency of the fingers to resist inward movement. In some embodiments, once the tail tip 232 is completely disengaged from the safety hole 247, the elasticity of the first finger 233, the second finger 234 can force the distal end back to the original expanded position. In such an embodiment, first finger 233, second finger 234 may expand to a width greater than the width of the entrance to safety hole 247, thereby preventing or limiting the ability to reinsert tail tip 232 into the safety hole. . In such an embodiment, a potential user of the decontamination device 100 may know that the device may not be complete because the pull safety device 218 has been previously removed. In some embodiments, first finger 233 , second finger 234 may not spring back into place, but instead be permanently deformed when removed from safety hole 247 . In such an embodiment, the tail tip 232 may not be securely seated within the safety hole 247 because the finger cam 236 and first finger 233, second finger 234 do not abut outwardly against the wall of the safety hole. superior. Thus, in such an embodiment, a potential user may also be alerted to the fact that the pull safety device 218 has been previously removed and the canister may be full.
