SPRAYER AND ASSEMBLY AND USE METHODS Background of the Invention Often, conventional sprinklers are bulky, cumbersome, difficult to operate, or unable to withstand common overload conditions. Consequently, there is a desire for a sprinkler with design features that reduce its overall size and weight; facilitate manufacturing; maintain functionality and safety while withstanding loads such as overload torque and long-term spring stress; produce high-quality spray patterns and improve the quality of viscous spray by reducing pressure losses along the flow path; increase the number of times the device can be reused; ensure the actuation mechanism is easily operated and returns reliably; and achieve a drip-free spray pattern. Brief Description of the Invention According to one aspect, a spray device or sprinkler includes a bottle portion, a sleeve, and a motor. The motor includes a spring that, when compressed, pressurizes a chamber containing a distributable amount of fluid from the bottle portion. The sleeve and motor are configured to apply torque to the Ref. 327658 bottle without compressing the spring. According to another definition, a sprayer includes a bottle portion, a sleeve, and a motor. Rotation of the sleeve relative to the bottle by a user pressurizes a chamber containing fluid from the bottle. The sleeve is configured to provide auditory and / or tactile feedback to the user during rotation, allowing them to select the amount of fluid to be dispensed. According to another definition, a sprayer includes a bottle, a sleeve, and a motor. The motor includes a spring that, when compressed, pressurizes a chamber containing a distributable amount of fluid from the bottle. The spring is enclosed between a cup and a cap, which have been cast together. Brief Description of the Figures Figure 1 shows a front view of a sprinkler.

Detailed Description of the Invention Obviously, it should be understood that the description and figures herein are for illustrative purposes only and that various modifications and changes can be made to the described structures without deviating from this description. With reference to the figures below, where the same numbers refer to the same parts across all views, Figure 1 depicts a device. CMtC I n / l 7P7 / B / YILI of spray or sprinkler 100 including an upper portion 102 and a bottle portion 104. The sprinkler 100 includes an outer sprinkler surface 110 defining a substantially cylindrical profile taken from a front view as shown in Figure 1. The upper portion 102 includes a sleeve 112 configured to receive the bottle portion 104 such that the upper portion 102 is flush with the bottle portion 104. Thus, the outer sprinkler surface 110 is continuous between the upper portion 102 and the bottle portion 104 when the bottle portion 104 is engaged with the upper portion 102. The substantially cylindrical profile of the outer sprinkler surface 110 defines a longitudinal sprinkler axis 114. Sprinkler 100 is configured to distribute liquid spray in a process that includes a priming stage and a distribution stage. The priming stage of sprinkler 100 is depicted in Figure 2, where the upper portion 102 is rotated clockwise around the longitudinal axis of sprinkler 114 relative to the bottle portion 104. As shown, the outer surface of sprinkler 110 is configured to be gripped by a user at each of the upper portion 102 and the bottle portion 104, where a two-handed twist or turn primes sprinkler 100 and dispenses a dose of liquid spray as a distribution quantity for the CMtC I n / l 7P7 / B / YILI distribution stage. The liquid spray is formed from a fluid that could be a gas and / or a liquid and could include particles, filaments, or other non-liquid elements suspended in it without departing from the scope of this description. Because the upper portion 102 is flush with the bottle portion 104, a user could grip the outer surface of sprinkler 110 at a location that overlaps both the upper and lower portions, forming an ergonomic gripping surface on the outer surface of sprinkler 110 between the upper and bottle portions. As shown, the upper portion 102 is rotated clockwise relative to the bottle portion 104 to prime sprinkler 100; however, sprinkler 100 could alternatively be configured so that the priming stage requires the upper portion 102 to be rotated counterclockwise relative to the bottle portion 104 without departing from the present description.Also, the sprayer 100 could alternatively be configured so that the priming stage requires the upper portion 102 to be turned either clockwise or counterclockwise relative to the bottle portion 104, or a series of clockwise directions. CMtC I n / l 7Π7 / Β / YΙΛΙ clockwise and / or counterclockwise with respect to bottle portion 104 without departing from the scope of this description. Figure 3 depicts the distribution stage, where an upper surface of upper portion 120 defined by a button 122 is pressed to release the liquid spray 124 from a nozzle 130. The nozzle 130 is inserted into the upper portion 102 and is configured to distribute the liquid spray 124 in a direction that is substantially radially outward from the outer surface of sprinkler 110 and substantially perpendicular to the longitudinal axis of sprinkler 114. Figure 4 shows an exploded view of sprinkler 100. As shown, a motor 132 is housed in sprinkler 100 between the upper portion 102 and the bottle portion 104. The motor 132 is configured to supply liquid spray to the nozzle 130 of a dip tube 134 that extends into the bottle portion 104 when sprinkler 100 is assembled, providing the motor 132 with access to the liquid spray contained in the bottle portion 104. A spray channel 140 can be selectively engaged with the motor 132, which includes a cap 142, a vent 144, and a cup 150 located in line with the upper portion 102 and the bottle portion 104 along the longitudinal axis of sprinkler 114. CMtC I n / l 7Π7 / Β / YΙΛΙ Figure 5 shows a vertical cross-section of the sprinkler 100 with the motor 132 assembled and housed in the upper portion 102 and the bottle portion 104. As shown, the spray channel 140 is diverted upward along the longitudinal axis of the sprinkler 114 toward the button 122 by a return spring 152 located between the spray channel 140 and a screw 160. A stem 162 is inserted into a stem entry 164 of the spray channel 140, which is centered on the longitudinal axis of the sprinkler 114. The spray channel 140 supports the nozzle 130 in the upper portion 102 such that the nozzle 130 is aligned with a spray slit 170 defined in the upper portion 102. The cup 150 is threaded onto the bottle portion 104 so that the cup 150 engages and retains the cap 142, a main spring 172, a nut 174, and a piston 180 with the bottle portion 104. The cup 150, piston 180, and screw 160 in combination form a sealed chamber 182 with a volume that varies as the piston 180 slides along the cup 150 and the screw 160 moves in a direction parallel to the longitudinal axis of the sprinkler 114. The chamber 182 is effectively sealed so that no liquid spray escapes from chamber 182 and no ambient air enters chamber 182. The dip tube 134 is housed in the cup 150, in selective fluid communication with chamber 182. A ball 184 is seated in the cup 150 to form a valve. a CMtC I n / l 7P7 / B / YILI via between immersion tube 134 and chamber 182 that allows liquid spray to enter chamber 182 of immersion tube 134 and prevents liquid spray from leaving or exiting chamber 182 into immersion tube 134. The main spring 172 is located between and contained within the cup 150 and the cap 142. The main spring 172 is a compression spring centered and directed along the longitudinal axis of sprinkler 114 and is configured to deflect the piston 180 toward the bottom of the cup 190. The main spring 172 includes an upper spring end 192 that supports the cap 142 and a lower spring end 194 that supports the nut 174, where the nut 174 is configured to pass an elastic force exerted or applied by the main spring 172 on the cup 150 through the piston 180. The nut 174 is also threaded with the screw 160, such that the rotational movement of the screw 160 about the longitudinal axis of sprinkler 114 causes the linear translation of the nut 174 along the longitudinal axis of sprinkler 114. In an interconnection between sleeve 112 and bottle portion 104, a lower end portion of sleeve 200 extends downward around an upper end portion of bottle portion 202 to support a lower protrusion of bottle portion 204 formed thereon, where a lower sleeve surface 210 of the lower end portion of sleeve 200 supports and engages, in a sliding manner, with the lower protrusion of bottle portion 204. An inner surface of sleeve 212 and an outer surface of bottle portion 214 are rounded with respect to the longitudinal axis of sprinkler 114 and are radially separated from each other with respect to the longitudinal axis of sprinkler 114. In this way, the upper portion 102 and the bottle portion 104 are configured to rotate or pivot relative to each other when the bottle portion 104 is engaged with the upper portion 102. Figure 6 depicts the sleeve 112, which includes the lower end portion of sleeve 200, an upper end portion of sleeve 220 configured to receive button 122, the outer surface of sprinkler 110 on the upper portion 102, and the spray slit 170. As shown, the spray slit 170 extends integrally from the upper portion 102 in a direction radially outward from the longitudinal axis of sprinkler 114 when the upper portion 102 is assembled with sprinkler 100. The spray slit 170 is configured to form a gap with a cone of liquid spray distributed from nozzle 130. Figure 7 shows a partial view of sleeve 112, exposing at least one sleeve flange 222, a click blade 224, an upper sleeve bearing 230, and a lower sleeve bearing 232. As shown, at least the sleeve flange 222 extends along the upper end portion of sleeve 220, parallel to the longitudinal axis of sprinkler 114 when the upper portion 102 is assembled with the sprinkler 100. At least the sleeve flange 222 extends through the upper sleeve bearing 230, into the lower end portion of sleeve 200. At least the sleeve flange 222 is configured to restrict the spray channel 140 in a rotational position about the longitudinal axis of sprinkler 114 with respect to the sleeve 112 and transfers the torque about the longitudinal axis of sprinkler 114 between sleeve 112 and spray channel 140.The click blade 224 is located on a lower portion of sleeve flange 234 of at least the sleeve flange 222, extends into the cap 142, and is configured to produce at least one audible click with complementary features of the cap 142 when the upper portion 102 is rotated relative to the bottle portion 104, indicating to the user that a dose of the liquid spray is being loaded. The upper sleeve bearing 230 includes an upper bearing retainer 240 configured to restrict the cap 142 to a longitudinal position of the sleeve 112 with respect to the longitudinal axis of the sprinkler 114. The lower sleeve bearing 232 is configured to surround a circumference of CMtC I n / l 7Π7 / Β / YILI the main wall of cover 290 to restrict the cover 142 radially around the longitudinal axis of sprinkler 114 with respect to the sleeve 112 when the sprinkler 100 is assembled. Figure 8 shows a cross-sectional view of cup 150. As shown, the lower portion of cup 190 forms a downward axial bearing for screw 160, and cup 150 further includes a cup wall 242 formed by an upper portion of cup wall 244 and a lower portion of cup wall 250. The upper portion of cup wall 244 is a radial bearing for screw 160, and at least one cup wall guide 252 is defined on an inner surface of cup wall 254 in the upper portion of cup wall 244. At least one cup wall guide 252 is complementary to the radially outward orientation configurations of nut 174 and is configured to capture at least the respective configuration of nut 174 to rotationally constrain nut 174 with respect to cup 150 about the longitudinal axis of sprinkler 114. The inner surface of cup wall 254 in the lower portion of cup wall 250 forms chamber 182 with piston 180. For this purpose, the inner surface of cup wall 254 in the lower portion of cup wall 250 is a sealing surface configured to engage and form a seal with piston 180 effective to prevent leakage or escape of liquid spray or penetration of the ambient atmosphere into chamber 182. A dip tube inlet 260 is centered on the bottom of cup 190 and defined on the bottom of cup 190 through a cup passage 262 of a cup ball valve seat 264 along the longitudinal axis of sprinkler 114. The dip tube inlet 260 is configured to receive dip tube 134, securing dip tube 134 with cup 150 and placing dip tube 134 in fluid communication with the cup ball valve seat 264. The cup ball valve seat 264 is configured to receive ball 184 to form the one-way valve. At least one cup flange 270 extends integrally radially outward from the upper portion of the cup wall 244, at least the cup flange 270 that is configured to engage with the bottle portion 104 to secure the cup 150 to the bottle portion 104. An outer cup flange face 272 of at least the cup flange 270 includes at least one sleeve bearing 274 configured to support the inner surface of sleeve 212 when the cup 150 is assembled with sleeve 112. When sleeve 112, bottle portion 104, and cup 150 are assembled, at least the sleeve bearing 274, sleeve 112, and bottle portion 104 occupy the same longitudinal position CMtC I n / l 7P7 / B / YILI of the sprinkler 100 so that a radial force applied to the sprinkler 100 in the longitudinal position passes through each of at least the sleeve bearing 274, the sleeve 112 and the bottle portion 104. At least the cup flange 270 further includes at least one vent retainer clip 280 extending radially inward from an inner surface of cup flange 282 in a longitudinal position located toward the upper portion of cup wall 244. In the illustrated embodiment, when the sprinkler 100 is assembled, the cup 150 is concealed from view from the outside of the sprinkler 100 by at least the sleeve 112. However, in an alternative embodiment, an outer flange of the cup 150 is exposed to view from the outside of the sprinkler 100, for example, through a combination of an extension of at least the cup flange 270 and a cut-out sleeve 112. This alternative embodiment allows the exposed outer flange to serve as a non-rotating surface that can be gripped by the equipment for threading the upper portion 102 onto the bottle without loading the motor 132 when the sprinkler 100 is assembled. As shown in Figure 9, the lid 142 includes a lid top face 284, a lid main wall 290, a lid flange 292 extending from the lid main wall 290, a lid weld wall 294, and a lid bottom face 300. The lid main wall 290 extends CMtC I n / l 7P7 / B / YILI integrally downwards and radially outwards from the top face of cap 284 to the cap flange 292, and the cap weld wall 294 extends integrally downwards from the main cap wall 290 to receive the twist weld geometry of cup 150 on the upper portion of cup wall 244. In one embodiment, cap 142 and cup 150 are formed from the same material and twist welded together to form a single unit, characteristic of integrally formed components. In additional embodiments, the material choice for cap 142 and cup 150 excludes the release of slip-mold or antistatic additives because these materials can adversely affect the quality of twist welds.In some embodiments, at least one of the cap 142 and cup 150 is formed from polypropylene (PP), and in additional embodiments, at least one of the cap 142 and cup 150 is formed from polyethylene terephthalate (PET). Notably, alternative materials having properties similar to PP and / or PET could be used in the cap 142 and / or cup 150 without departing from the scope of this description. In one alternative embodiment of the sprinkler 100, the cap 142 and cup 150 are joined using clips (not shown). In further alternative embodiments of the sprinkler 100, the cap 142 and cup 150 are joined using clips instead of being joined by twist welding. The 292 cap flange extends radially towards CMtC I n / l 7P7 / B / YILI outside the main wall of cover 290, with a radial circumference defined by an outer face of cover flange 302. A click channel 304 is defined in the cover flange 292 between the main wall of cover 290 and the outer face of cover flange 302 in a radial direction perpendicular to the longitudinal axis of sprinkler 114. The click channel 304 includes at least one click flange 310 located therein. The click blade 224 is positioned in the click channel 304 when the upper portion 102 is assembled with the cap 142, at least the click flange 310 is configured to engage the click blade 224 when the upper portion 102 is rotated relative to the bottle portion 104 and by extension, the sleeve 112 is rotated relative to the cap 142.When at least the click flange 310 engages with the click blade 224, an audible click is produced for the user operating the sprayer 100. This click corresponds to a dose of liquid spray being loaded to a given extent or range. The upper bearing retainer 240 of the sleeve 112 projects radially inward from the inner surface of the sleeve 212, and the cap flange 292 is configured to capture the upper bearing retainer 240, which engages with the outer face of the cap flange 302. As shown in Figure 10, at least one 312 screw retaining clip extends integrally downward and radially inward from the top face of the cap CMtC I n / l 7Π7 / Β / YΙΛΙ 284, at least the screw retaining clip 312 is configured to engage the screw 160 and to retain the screw 160 in the cap 142. In the embodiment shown, at least the screw retaining clip 312 is a six-clamp screw retaining clip; however, more or fewer similar screw retaining clips could be employed on the sprinkler 100 without departing from the scope of the present description. A cap 314 main spring contact face is defined on an inner surface of cap 316 configured to orient cup 150 when cap 142 and cup 150 are assembled. The cap 314 main spring contact face is configured to support and retain the main spring 172. Each of the cap 314 main spring contact face and the upper end of spring 192 can be flattened to increase the contact surface area between cap 142 and main spring 172 at the cap 314 main spring contact face and the upper end of spring 192. The underside of cap 300, which is located at a lower end of the weld wall of cap 320, is substantially flat toward cup 150 and is oriented substantially perpendicular to the longitudinal axis of sprinkler 114 when sprinkler 100 is assembled. Thus, the weld wall of cap 294, which includes the underside of CMtC I n / l 7P7 / B / YILI cap 300 is configured to engage with the weld geometry of cup 150. As depicted in Figure 8, the cup weld geometry includes a cup projection 322 with a cup top face 324 that defines the uppermost surface of cup 150. As depicted in Figure 5, the cup top face 324 and the cap bottom face 300 are substantially flat relative to each other and are oriented substantially perpendicular to the longitudinal axis of sprinkler 114 when sprinkler 100 is assembled. Also, the cap weld wall 294 surrounds and contacts the cup projection 322 to form a weld surface between cap 142 and cup 150. When the sprinkler 100 is assembled, the vent 144 is configured to provide a seal between the bottle portion 104 and the cup 150 to prevent the escape of liquid spray and allow ambient air to vent into the bottle portion 104 to replace the distributed liquid spray. As shown in Figure 11, the vent 144 is substantially ring-shaped and includes an inner vent face 330, an outer vent face 332, a vent top end portion 334, and a vent bottom end portion 340. The inner vent face 330 includes a vent cup retaining face 342 in the vent top end portion 334. CMtC I n / l 7Π7 / Β / YΙΛΙ 342 is configured to retain cup 150 in vent 144 and to form a seal with cup 150 when sprayer 100 is assembled. The inner face of vent 330 includes a lower inner face of vent 344 in the lower end portion of vent 340, and when vent 144 is sealed with cup 150 and bottle portion 104, the lower inner face of vent 344 continues with a sealing surface between cup 150 and bottle portion 104. The outer face of vent 332 includes a vent bottle sealing face 350 on the lower end portion of vent 340, which is configured to create a seal with bottle portion 104 when cup 150, bottle portion 104, and vent 144 are assembled. When cup 150, bottle portion 104, and vent 144 are assembled, cup 150 is engaged with the cup retaining face of vent 342, and bottle portion 104 is engaged with the sealing face such that the outer face of vent 332 continues with a sealed surface between cup 150 and bottle portion 104. Figure 12 shows a partial cross-section of vent 144. As shown, a vent slot 352 is defined in vent 144, on the inner face of vent 330 at the upper end portion of vent 334. A vent retainer 354 is formed on the inner face of vent 330 between the vent slot 352 and an upper face of vent 360. The vent retainer 354 is configured to retain vent 144 in cup 150. In one embodiment, vent 144 is formed from low-density polyethylene (LDPE). In another embodiment, vent 144 is formed from thermoplastic polyurethane (TPU). Notably, alternative materials similar to LDPE and TPU could be used in vent 144 without departing from the scope of this description. The spray channel 140 houses the nozzle 130 and provides a flow path for liquid spray between the stem 162 and the nozzle 130. As shown in Figure 13, a flow path is formed from the stem inlet 154 and a spray channel passage 362 defined in the spray channel 140. The spray channel passage 362 extends between the stem inlet 154 and a nozzle protrusion 364 configured to support the nozzle 130 in the spray channel 140. The stem inlet 154 is defined in the spray channel 140 with a radial location centered on the longitudinal axis of sprinkler 114 and an orientation parallel to the longitudinal axis of sprinkler 114 when sprinkler 100 is assembled.With this construction, the radial position of the stem 162 in the stem inlet 154 does not vary around the longitudinal axis of the sprinkler 114 when the upper portion 102, and by extension, the spray channel 140, is rotated relative to the bottle portion 104. An inner stem inlet surface 370 forms an interconnection with the stem 162, where the inner stem inlet surface 370 forms a seal with the stem 162 effective in maintaining the internal operating pressure between the stem 162 and the spray channel 140 without allowing any liquid spray to escape. The nozzle protrusion 364 is substantially cylindrical in shape and is thus configured to support the nozzle 130 without requiring a specific rotational position of the nozzle 130 with respect to the nozzle protrusion 364 and the spray channel 140. The spray channel 140 provides a clutch configured for selective engagement with the screw 160 to convert the rotational movement of the sleeve into a rotational movement of the screw and an axial movement of the nut. As shown in Figures 13 and 14, the spray channel 140 includes at least one spray channel leg 372 located radially outward from a spray channel ring segment 374, at least the spray channel leg 372 extending downward toward the cap flange 292 when the sprinkler 100 is assembled. Each of at least the spray channel legs 372 is configured for engagement with at least the sleeve flange 222 extending radially inward toward the sleeve 112.At least the spray channel leg 372 supports, respectively, at least the sleeve flange 222 in a rotational direction of the sleeve 112 relative to the bottle portion 104 around the longitudinal axis of the sprinkler 114 to transfer the rotational forces between at least the spray channel leg 372 and at least the sleeve flange 222. The spray channel ring segment 374 is supported on at least the spray channel leg 372 on an outer surface of the spray channel ring segment 380 and characterizes at least one spray channel clutch tooth 382 that extends radially inward from the spray channel ring segment 374 on an inner surface of the spray channel ring segment 384. Each of at least the spray channel clutch tooth 382 includes a leading segment 390 that is inclined from the spray channel ring segment 374 toward the sprinkler longitudinal axis 114, downward along the sprinkler longitudinal axis 114.In the embodiment shown, at least the spray channel clutch tooth 382 is one of six spray channel clutch teeth located between consecutive spray channel legs of at least spray channel leg 372 around the spray channel ring segment 374; however, more or fewer spray channel clutch teeth with varying distribution patterns along the spray channel ring segment 374 could be employed without departing from the scope of the present description. At least the spray channel clutch tooth 382 is configured to engage directly with screw 160 and to transmit torque between screw 160 and spray channel 140. At least the spray channel clutch tooth 382 includes a clutch tooth clamp 392 extending toward the return spring 152.

At least the bottle portion stop 732 is a rotational end stop for cup 150 during coupling of cup 150 to bottle portion 104 and during loading of a dose of the liquid spray.With this construction, the cup 150 is screwed onto the bottle portion 104 until the bottle portion 104 supports the upper shoulder of bottle portion 710 and at least the stop of bottle portion 732, where at least the retainer of bottle portion 730 rotationally retains the cup 150 with the bottle portion 104, securing the cup 150 with the bottle portion 104. The lower shoulder of bottle portion 204 is configured to support sleeve 112 on bottle portion 104 and allow sleeve 112 to rotate about the longitudinal axis of sprinkler 114 relative to bottle portion 104. To this end, the outer surface of bottle portion 214 on the lower neck of bottle portion 720 is smooth and rounded about the longitudinal axis of sprinkler 114, and the inner surface of sleeve 212 on the lower neck of bottle portion 720 is smooth and rounded about the longitudinal axis of sprinkler 114 to fit around the lower neck of bottle portion 720. Bottle portion 104 has a liquid spray reservoir and is only resistant to liquid spray. As an external component of sprayer 100, bottle portion 104 is also impact resistant. In one embodiment, bottle portion 104 is formed from polyethylene terephthalate (PET). In another embodiment, the bottle portion is formed from polypropylene (PP). Notably, bottle portion 104 could be designed to a variety of specific tolerances and / or formed from a variety of similar materials without departing from the scope of this description. Bottle portion 104 can be replaced with the remainder of sprinkler 100. Bottle portion 104 is removed from sprinkler 100 by rotating it relative to sleeve 112 in the opposite direction when sprinkler 100 is loading a dose of liquid spray, as shown in Figure 34, and pulling bottle portion 104 off sleeve 112, as shown in Figure 35. Sprinkler 100 requires a torque to thread cup 150 onto bottle portion 104 that is less than the torque required to load a dose of liquid spray into sprinkler 100. This allows assembly of cup 150 and bottle portion 104 without loading sprinkler 100. The alternative sprinkler design 100 could be employed to bring an abrupt end to the distribution of a liquid spray dose. Figure 36 depicts a modality of sprinkler 100 where the piston 180 is an end stop. For this purpose, as depicted, the piston 180 terminates the distribution of a liquid spray dose by contacting the bottom of the cup 190 so that the main spring 172 cannot pressurize the liquid spray. As depicted, a lower surface of piston 734 is substantially flat with a slope toward the bottom of cup 190 about the longitudinal axis of sprinkler 114, and the bottom of cup 190 includes a top surface of cup 740 that is complementary to the lower surface of piston 734. The top surface of cup 740 is flat with a radial slope away from the piston 180 about the longitudinal axis of sprinkler 114. Figures 37 and 38 depict an alternative embodiment of sprinkler 100 where the ball 184 is replaced with a relief valve 742 configured to allow liquid spray to enter chamber 182 of the dip tube 134 and prevent liquid spray from exiting chamber 182 into the dip tube 134. For this purpose, the relief valve 742 is configured to move from an open to a closed position and to remain closed from the beginning of the liquid spray distribution, as depicted in Figure 37, until the end of the liquid spray distribution, as depicted in Figure 38. When the relief valve 742 is moved to the open position, a flow path for the liquid spray is opened through the relief valve 742 to allow the liquid spray to travel from the dip tube 134 to chamber 182.The end of the liquid spray distribution occurs when piston 180 is driven downwards so that a piston lift 744 engages with the exhaust valve 742 and cup 150 and drives the exhaust valve 742 into the closed position by pressing sufficiently downwards on the exhaust valve 742. As depicted in Figure 39, the exhaust valve 742 is formed from an exhaust valve ball 750, which includes an exhaust valve ball sealing surface 752 and a tail 754. The exhaust valve ball sealing surface 752 creates a seal with the cup 150 when the exhaust valve 742 is seated in the cup 150. The tail 754 extends radially outward from the exhaust valve 742 and is configured to be pressed by the piston 180 to actuate the exhaust valve 742 to the closed position and to be otherwise pressed by fluid pressure in the liquid spray to actuate the exhaust valve 742 to the open position. Thus, the end of the liquid spray distribution occurs when the tail 754 is actuated sufficiently downward by the piston 744 to actuate the exhaust valve 742 to the closed position. An alternative to the ball 184 and exhaust valve 742 embodiments shown in Figures 36-39 is a valve formed through screw holes. In this embodiment, the screw holes are formed by laser drilling. Figures 40-51 depict steps in a method of assembling sprinkler 100. Figure 40 shows the vent 144 assembled with the cup 150, where the vent retainer 354 captures the cup 150, securing the vent 144 to the cup 150. Notably, rotational alignment between the cup 150 and the vent 144 is not required for the assembly of the cup 150 and the vent 144. Figure 41 shows the ball 184 being dropped into the cup 150, seated on the cup ball valve seat 264. A subsequent step in the method of assembling sprinkler 100 includes assembling the piston 180 with the nut 174, as depicted in Figure 42, and lubricating the outer flat portion of the piston 642 before assembling the piston 180 and nut. 174 with cup 150 as depicted in Figure 43.As depicted, nut 174 and cup 150 have complementary features in at least cup wall guide 252 and at least one nut outer wall shoulder 592 which, when engaged, maintains rotational alignment between nut 174, piston 180, and cup 150. Figure 44 shows the main spring 172 uncompressed and dropped into nut 174 so that the lower end of spring 194 rests on the floor of nut 584, between the inner wall of nut 580 and the outer wall of nut 582. A lubricant is applied to the main spring 172 or the cap 142 on the underside of cap 300 where the main spring 172 contacts cap 142. As shown in Figure 45, cap 142 is lowered onto the main spring 172 and cup 150, compressing the main spring 172 so that it is subjected to stress at the sprayer 100. Cup 150 and cap 142 are twist-welded together, forming a single unit containing the main spring 172. In one embodiment of the assembly method, the cup 150 and the lid CMtC I n / l 7Π7 / Β / YΙΛΙ 142 are cooled, in a fixed manner, after being subjected to twist welding. The upper end of spring 192 and the lower end of spring 194 are ground to mate, respectively, with the cap 142 and the nut 174. In one embodiment, the main spring has a length-to-diameter ratio of approximately 3.95; however, a variety of length-to-diameter ratios could be employed in the main spring 172 without departing from the scope of the present description. Figure 46 depicts screw 160 assembled with cup 150, piston 180, nut 174, and cap 142. Before screw 160 is inserted through cap 142, nut 174, and piston 180, screw thread 552 and screw sealing face 560 are located. Figure 47 depicts valve 494 inserted within screw 160, with the valve outer wall 502 forming a seal with the screw sealing surface. Valve 494 is secured relative to screw 160 by a valve retainer 504, which captures a screw retainer 760 complementary to valve retainer 504. Figure 48 depicts a spray channel subassembly 762 formed from the spray channel 140 assembled with the nozzle 130, stem 162, and return spring 152. As depicted, the stem 162 is inserted into the stem inlet 154 until the stem flange 434 bears a face CMtC I n / l 7Π7 / Β / YILI of lower end of spray channel 764. The return spring 152 is seated on the face of lower end of spray channel 764 around the stem 162 and the nozzle 130 is inserted over the nozzle protrusion 364. The spray channel subassembly 762 is assembled with the valve 494 and screw 160 in Figure 49. As depicted, the stem 162 is inserted into the valve 494, the return spring 152 is seated on the screw 160, supported by the screw retainer 760, and at least the spray channel clutch tooth 382 is positioned with at least the screw clutch tooth 550. Figure 50 shows the sleeve 112 assembled with the motor 132. As shown, at least the sleeve bearing 274 makes contact with the inner surface of sleeve 212 to fix the cup 150 in a radial position with the sleeve 112, with respect to the longitudinal axis of sprinkler 114. Also, the upper bearing retainer 240 captures the cap flange 292, fixing the cap 142 in a longitudinal position with respect to the sleeve 112. Figure 51 shows an assembled sprinkler 100, where the dip tube 134 is inserted into the dip tube inlet 260 and the bottle portion 104 is fixed in the cup 150, over the dip tube 134. Figures 52-54 depict a method for loading and distributing a liquid spray dose with the sprinkler CMtC I n / l 7Π7 / Β / YΙΛΙ 100. As depicted in Figure 52, the sleeve 112 is rotated relative to the bottle portion 104 so that the main spring 172 is compressed and presses the piston 180 and nut 174 against the cap 142. The nut 174 and piston 180 are also moved to slide along the cup 150 so that the piston 180 draws a dose of the liquid spray, as a distributable amount of fluid, into chamber 182. Thus, a torque applied to the motor 132, which compresses the main spring 172, draws a distributable amount of fluid into chamber 182. As also depicted in Figure 52, the ball valve formed between the ball 184 and the cup 150 is closed, preventing the liquid spray from returning to the bottle portion 104 of the chamber 182. Because the valve 494 is closed by the stem 162, the liquid in the chamber 182 cannot escape, and the piston 180 remains stationary. Under these circumstances, a dose of liquid spray is loaded into the sprinkler 100. At least the bottle portion stop 732 prevents excessive compression of the main spring 172 and the consequent overloading of the sprinkler 100. Notably, the aspects of loading torque, cup pressure, the compression force required by the button, and the volume of liquid spray distributed are illustrative and may be modified without departing from the scope of this description. As depicted in Figure 53, button 122 is pressed down, disengaging at least the spray channel clutch tooth 382 and at least the screw clutch tooth 550. When button 122 is pressed, the spray channel 140 pushes the stem 162 down through the valve 494, pushing at least the stem bore 442 past the inner surface of the valve inner wall 514 and opening a flow path for the liquid spray through the stem 162. With a flow path from chamber 182 to open the nozzle 130, the pressure from the main spring 172 drives the piston 180 to contract the chamber 182 and distribute a dose of the liquid spray through the screw 160, the stem 162, the spray channel 140, and the nozzle 130.Because button 122 could be released at any time, when screw 160 could be at any point of rotation relative to spray channel 140, at least the spray channel clutch tooth 382 is configured to engage with at least the screw clutch tooth 550 at any relative rotational angle to facilitate the return of button 122 to an extended position. As shown in Figure 54, the liquid spray distribution ends when the lower surface of piston 734 makes contact with the bottom of cup 190, terminating with the pressure exerted on chamber 182 by the main spring 172. The liquid spray distribution could also end when the user releases pressure on button 122, which repositions at least the stem hole 442 back into the valve 494, sealing off fluid flow between stem 162 and screw 160. The process of releasing pressure from button 122 from the extended position begins with the disengagement of at least the screw clutch tooth 550 from at least the spray channel clutch tooth 382, ​​which allows screw 160 to rotate relative to the spray channel 140, enabling the main spring 172 to move nut 174 and, by extension, piston 180 downward, contracting the chamber. 182.The sprayer 100 is configured to disengage at least the screw clutch tooth 550 from at least the spray channel clutch tooth 382 before uncovering at least the stem hole 442 below the valve 494 with respect to the screw 160. Uncovering at least the stem hole 442 opens a flow path from the chamber 182 to the nozzle 130. When the button 122 is fully pressed, the spray channel 140 moves out of the cap 142, where a lower end of the spray channel leg 770 of at least the spray channel leg 372 supports the cap 142. Figure 55 depicts a travel sequence of button 122 that corresponds to the disengagement of at least screw clutch tooth 550 from at least spray channel clutch tooth 382. As depicted in a first button movement sequence 772, button 122 travels a total distance of approximately 4 mm between the extended position and the position outside the lowered position. The disengagement of at least screw clutch tooth 550 engages at least spray channel clutch tooth 382 as the first button movement sequence 772 occurs through the first travel of approximately 2.5 mm of button 122. Button 122 travels an additional approximately 0.6 mm as a clearance 774 ensures that at least screw clutch tooth 550 is fully disengaged from at least spray channel clutch tooth 382 and approximately 1.8 mm of additional travel of button 122 is a second sequence of movement of button 780 that corresponds to the uncovering of at least the stem hole 442 below the valve 494. An additional 0.1 mm of travel of button 122 occurs before button 122 reaches the position out of the lower position. As shown in Figures 56 and 57, the click blade 224 and at least the click flange 310 together form a click device that produces an audible click when the sleeve 112 rotates an incremental distance relative to the cap 142. With a click produced at each incremental distance traveled by the sleeve 112 relative to the cap 142, the click device indicates the expression in which the sprinkler 100 is loaded and how much liquid the sprinkler sprays. CMtC I n / l 7Π7 / Β / YΙΛΙ 100 is configured for distribution. Notably, the sleeve 112 and the cap 142 do not rotate relative to each other when the liquid spray is being distributed, so the click device does not produce audible clicks when the liquid spray is being distributed. As depicted, at least the click flange 310 consists of four click flanges situated around the click channel 304, so that the click device could produce four audible clicks as the sprinkler 100 is being loaded; however, a different number of click blades 224 and click flanges 310 could be employed on the sprinkler 100 to produce a different number of audible clicks with respect to a different rotation interval between the sleeve 112 and the cap 142, without departing from the scope of the present description. In an alternative embodiment of sprinkler 100, as shown in Figure 58, at least the cup flange 270 is extended and configured to be exposed below the sleeve 112 and forms part of the outer surface of sprinkler 110 with the bottle portion 104. With this construction, at least the cup flange 270 is configured to be rotated about the longitudinal axis of sprinkler 114 independently of the screw 160 and without applying any torque to the motor 132, and is only linked by the torque applied through the threaded section of the end portion. CMtC I n / l 7P7 / B / YILI upper of bottle portion 202. With this construction, it is possible to cap the 100 after filling the bottle portion 104 without loading the sprayer 100. Because the liquid spray does not require a propellant, the bottle portion 104 could be completely filled with the liquid spray without leaving room for the propellant in the bottle portion 104. It will be appreciated that various modalities of the features and functions described above, and other or alternative variations thereof, could be combined, desirably, in many other different application systems. It is also claimed that various alternatives, modifications, variations, or improvements not currently foreseen or anticipated herein may subsequently be made by persons skilled in the art, which are also intended to be included by the following claims. It is hereby stated that, as of this date, the best method known to the applicant for putting the aforementioned invention into practice is the one that is clear from the present description of the invention.
