[0007] The present invention generally relates to an outer cover assembly including a body and a start button, and more specifically, to a dual-nozzle outer cover assembly having spherical, curved or inclined discharge holes. Background Technology

[0008] Pressurized containers are commonly used for storing and dispensing volatile materials, such as air fresheners, deodorizers, insecticides, fungicides, decongestants, and perfumes. Volatile materials are typically stored in a pressurized and liquefied state within the container. The product is forcibly expelled from the container via an aerosol valve using either a hydrocarbon or non-hydrocarbon propellant. A release valve with an outwardly extending stem can be provided to facilitate the release of volatile materials from the top of the container, thereby activating the valve via the stem and allowing the volatile materials to flow out of the container and into the outside atmosphere. The release valve is typically activated by tilting, pressing, or otherwise moving the stem. A typical valve assembly includes a stem, a body, and a spring. The stem extends through a base, with its distal end extending upwards away from the base and its proximal end positioned within the body.

[0009] Pressurized containers often include an outer cap assembly that covers the top of the container. A typical outer cap assembly is releasably attached to the container by an outwardly projecting ridge that intersects the inner lower edge of the outer cap assembly and interacts with a bead or seam on the top of the container. When the outer cap assembly is placed on top of the container, downward pressure is applied to the outer cap assembly, causing the ridge to ride over the outer edge of the seam and lock below a frame-like projection defined by the lower surface of the seam.

[0010] A typical cap assembly includes mechanisms for engaging a valve stem with the container. Some actuator mechanisms may include a linkage that applies downward pressure to press the valve stem and open a valve inside the container. In cases where the container has a valve stem actuated by tilting, other actuation mechanisms may instead apply radial pressure. In all cases, these actuation mechanisms provide a relatively convenient and easy-to-use interface for the end user.

[0011] Conventional starting mechanisms include a start button or a start trigger. A traditional start button may include a vent located either along a portion of the button or at a separate location along the body or base of the outer cover assembly. Regardless of the vent's location, volatile materials typically flow through a fluid passage after user activation. The portion defining the passage usually engages with the valve stem of the relevant container. Therefore, when dispensing is required, the user activates the device by pressing the starter, which in turn presses the valve stem and opens the valve within the relevant container, releasing the contents of the container through the fluid passage and draining them from the vent.

[0012] In other containers, the valve stem is tilted or displaced in a direction transverse to the longitudinal axis to actuate the valve stem radially. When the valve assembly is opened, the pressure difference between the interior of the container and the atmosphere forces the contents of the container to drain through the orifice of the valve stem.

[0013] Conventional cover assemblies may include one or more nozzles extending from the start button. Existing start systems utilizing multiple nozzles present numerous problems. In particular, many existing start systems with multiple nozzles extending from the start button experience warping or deformation along the nozzles during use. Furthermore, existing start systems with multiple nozzles suffer from poor fluid atomization and spray paths that collide with or touch the outer walls of the nozzles and backflow, causing pooling in the area surrounding the nozzles. Additionally, existing start systems with multiple nozzles require complex manufacturing processes and demanding molding operations. The cover assembly described below overcomes these and other drawbacks of the prior art. Summary of the Invention

[0014] According to a first aspect, an outer cover assembly is configured to attach to a container. The outer cover assembly includes a body, an actuator, a first nozzle, and a second nozzle. The actuator is integrally attached to the body and defines a longitudinal axis. The actuator also includes a fluid channel extending therein. The first nozzle and the second nozzle extend laterally from the actuator and define a portion of the fluid channel. The first nozzle includes a first inclined discharge orifice, and the second nozzle includes a second inclined discharge orifice. The first nozzle and the second nozzle each include an inner cylindrical wall and an outer cylindrical wall, the outer cylindrical wall surrounding and spaced apart from the inner cylindrical wall. The first inclined discharge orifice and the second inclined discharge orifice are not parallel to the longitudinal axis.

[0015] According to some embodiments, the first and second inclined discharge orifices include spherical openings. In some embodiments, the angle between fluid flowing from the first and second inclined discharge orifices is between about 9° and about 15°. In some embodiments, the first and second nozzles each include an internal space defined between the inner cylindrical wall and the outer cylindrical wall. The inner cylindrical wall of the first nozzle defines the first inclined discharge orifice, and the inner cylindrical wall of the second nozzle defines the second inclined discharge orifice. In some embodiments, the first and second nozzles are orthogonal to the longitudinal axis. In some embodiments, the first and second inclined discharge orifices are configured to direct fluid in a divergent direction.

[0016] According to another aspect, a start button includes a vertical conduit, a first horizontal conduit, and a second horizontal conduit. The vertical conduit includes a length L1 and is configured to receive fluid when the start button is pressed. The first horizontal conduit extends laterally from the vertical conduit. The first horizontal conduit includes a first discharge port and is in fluid communication with the vertical conduit. The first horizontal conduit also includes a length L2. The second horizontal conduit extends laterally from the vertical conduit below the first horizontal conduit. The second horizontal conduit includes a second discharge port and is in fluid communication with the vertical conduit. The second horizontal conduit also includes a length L3. The first discharge port and the second discharge port are configured to direct the fluid in a divergent direction. The length L2 of the first horizontal conduit or the length L3 of the second horizontal conduit is greater than the length L1 of the vertical conduit.

[0017] According to some embodiments, the first horizontal conduit defines a first longitudinal axis, and the second horizontal conduit defines a second longitudinal axis. The first longitudinal axis is parallel to the second longitudinal axis. In some embodiments, the first discharge port and the second discharge port include spherical openings inclined relative to the first longitudinal axis and the second longitudinal axis, respectively. The first discharge port is inclined upwards at about 90° to about 170° relative to the first longitudinal axis, and the second discharge port is inclined downwards at about 90° to about 170° relative to the second longitudinal axis. In some embodiments, the first discharge port is configured to guide the fluid in an upward direction relative to the first longitudinal axis, and the second discharge port is configured to guide the fluid in a downward direction relative to the second longitudinal axis. In some embodiments, the activation button further includes a first inner cylindrical wall defining a portion of the first horizontal conduit, a first outer cylindrical wall surrounding the first inner cylindrical wall, a second inner cylindrical wall defining a portion of the second horizontal conduit, and a second outer cylindrical wall surrounding the second inner cylindrical wall. A first internal space is defined between the first outer cylindrical wall and the first inner cylindrical wall. A second internal space is defined between the second outer cylindrical wall and the second inner cylindrical wall. In some embodiments, the first horizontal catheter and the second horizontal catheter extend orthogonally from the vertical catheter.

[0018] According to another aspect, an outer cover assembly is configured to attach to a container. The outer cover assembly includes a body, an actuator, a first nozzle, and a second nozzle. The actuator is integrally attached to the body and defines a longitudinal axis. The actuator includes a fluid passage configured to receive fluid when the actuator is pressed. The first nozzle extends laterally from the actuator and defines a portion of the fluid passage. The first nozzle includes a first discharge orifice. The second nozzle extends from the actuator, parallel to the first nozzle, and defines a portion of the fluid passage. The second nozzle includes a second discharge orifice. When the actuator is pressed, the fluid pressure at the first discharge orifice is highest near the bottom of the first nozzle. Furthermore, when the actuator is pressed, the fluid pressure at the second discharge orifice is highest near the top of the second nozzle.

[0019] According to some embodiments, the first nozzle includes a first horizontal conduit defining a first longitudinal axis, and the second nozzle includes a second horizontal conduit defining a second longitudinal axis. The first discharge orifice is inclined relative to the first longitudinal axis, and the second discharge orifice is inclined relative to the second longitudinal axis. The first discharge orifice and the second discharge orifice include spherical openings. In some embodiments, the first nozzle and the second nozzle extend from the actuator orthogonally to the longitudinal axes. Attached Figure Description

[0063] As used herein, the term “about” refers to possible variations in numerical quantities, such as those arising from typical measurement and manufacturing procedures used in product dispensing systems or other articles of manufacture that may include embodiments disclosed herein; unintentional errors in these procedures; differences in the manufacture, origin, or purity of the ingredients used to manufacture compositions or mixtures or to perform methods; and similar variations. In this invention, the terms “about” and “approximately” refer to a range of ±5% of the preceding numerical value. Furthermore, as stated herein, all numerical ranges disclosed herein include their outer limits.

[0064] Figure 1 A product dispensing system 100 is depicted, comprising an outer cap assembly 102 and a container 104. The outer cap assembly 102 includes a body 110, an actuator or start button 112, a first nozzle 120, and a second nozzle 122. The first nozzle 120 and the second nozzle 122 extend outwardly from the start button 112 and are parallel to each other. The start button 112 is at least partially disposed within the body 110 to facilitate product dispensing from the dispensing system 100. In use, the outer cap assembly 102 is adapted to release product from the container 104 when certain conditions occur (e.g., manual pressing of the start button 112 by a user of the dispensing system 100). The dispensed product may be a formulation, carrier, or substance for use in a domestic, commercial, or industrial setting. The product is dispensed through a first inclined discharge port 130 of the first nozzle 120 and a second inclined discharge port 132 of the second nozzle 122. It is conceivable that the outer cap assembly 102 may include more or fewer nozzles than shown in the figure. For example, in one embodiment, the outer cover assembly 102 may include a third nozzle extending between the first nozzle 120 and the second nozzle 122.

[0065] In some embodiments, the product includes an insect repellent or pesticide disposed in a carrier liquid or the like. The product may also include other active substances, such as disinfectants, air fresheners, fragrances, deodorants, cleaners, odor eliminators, antifungal agents or fungicides and / or similar substances, and / or those with aromatherapy properties. The product may also include any solid, liquid, or gas known to those skilled in the art that can be dispensed from the container. It is conceivable that container 104 may contain any type of pressurized or unpressurized product, such as compressed gases that can be liquefied, non-liquefied, or dissolved, including carbon dioxide, helium, hydrogen, neon, oxygen, xenon, nitrous oxide, or nitrogen. Container 104 may also contain any type of hydrocarbon gas, including acetylene, methane, propane, butane, isobutene, halogenated hydrocarbons, ethers, mixtures of butane and propane, also known as liquefied petroleum gas or LPG, and / or mixtures thereof. Therefore, product dispensing system 100 is adapted to dispense any quantity of different products.

[0066] Container 104 and / or outer cover assembly 102 may each be made independently of any suitable material, including multiple layers of the same or different materials, such as polymers, plastics, metals (such as aluminum, aluminum alloys or tin-plated steel), glass, cellulose materials, laminates, recycled materials, and / or combinations thereof. The outer cover assembly 102 can be formed from a variety of well-known polymeric materials, including, for example, polyethylene (PE), low-density polyethylene (LDPE), high-density polyethylene (HDPE), polyethylene terephthalate (PET), crystalline PET, amorphous PET, polyethylene terephthalate, polystyrene (PS), polyamide (PA), polyvinyl chloride (PVC), polycarbonate (PC), polystyrene-acrylonitrile (SAN), polymethyl methacrylate (PMMA), polypropylene (PP), polynaphthalene (PEN), polyvinyl furanoate (PEF), PET homopolymer, PEN copolymer, PET / PEN resin blend, PEN homopolymer, supermolded thermoplastic elastomer (TPE), fluoropolymer, polysulfone, polyimide, cellulose acetate, and / or combinations thereof. It is further conceivable that the container 104 may include internal and / or external linings or coatings to further structurally reinforce the container 104 and make it resilient to highly irritating chemicals. The lining and / or coating may be made of any of the aforementioned polymer materials, or may be further made of ethylene-vinyl alcohol (EVOH). Container 104 may be opaque, translucent, or transparent.

[0067] like Figure 2 As best shown, container 104 includes a lower end 160 and a generally cylindrical body 162 terminating in a recess 164 located at an upper end 166 of container 104. As discussed below, outer cover assembly 102 can be attached to container 104 via recess 164 (see [reference]). Figure 4 Edge 168 is disposed adjacent to and above groove 164, and engages with platform 170, which partially defines the upper end 166 of container 104. Platform 170 is generally annular. It is conceivable that container 104 of the present invention can be a conventional aerosol container, which includes features pressed from the outside or inside into cylindrical body 162 and / or edge 168. For example, as Figure 2 As shown, the dome 176 can be pressed from the outside to the edge 168 of the container 104.

[0068] Still refer to Figure 2 The dome 176 of container 104 is generally spherical and extends upward from platform 170. An upwardly opening valve cup 178 is located at the center of dome 176 and is press-fitted or otherwise joined to dome 176 to form valve cup edge 180. Valve base 182 extends from the central portion of valve cup 178 and includes a conventional valve assembly (not shown in detail) with valve stem 184, which is connected to valve body (not shown) and valve spring (not shown) disposed within container 104. Valve stem 184 extends upward through valve cup 178, with the distal end 186 of valve stem 184 extending upward away from valve cup 178 and adapted to interact with the fluid inlet of actuation button 112 of outer cover assembly 102 (see [link to outer cover assembly 104]). Figure 4 The longitudinal axis A extends through the valve stem 184. It is also conceivable that other types of containers 104 or bottles may be used with the outer cap assembly 102 disclosed herein.

[0069] like Figure 3 and Figure 4 As shown in the optimal configuration, before use, the start button 112 is in fluid communication with the distal end 186 of the valve stem 184. The user can manually or automatically activate the start button 112 to open the valve assembly, thereby creating a pressure difference between the interior 188 of the container 104 and the atmosphere, forcing the contents of the container 104 to be discharged through the orifice 190 of the valve stem 184, through the outer cover assembly 102, and into the atmosphere.

[0070] Now convert parameters Figures 5 to 10 The outer cover assembly 102 is described in more detail. The body 110 of the outer cover assembly 102 is defined as having a lower portion 202 and an upper portion 204 extending from the lower portion 202. The lower portion 202 of the body 110 includes a lower sidewall 206 extending upward along a longitudinal axis A. As previously described, the longitudinal axis A is defined by the valve stem 184 of the container 104 and also by the actuation button 112. In this embodiment, the lower sidewall 206 of the lower portion 202 is generally cylindrical; however, the lower sidewall 206 may also be tapered. Furthermore, the lower sidewall 206 of the lower portion 202 also defines the lower edge 208 of the body 110. Figures 11 to 13As shown, the lower edge 208 of the lower part 202 is generally circular and defines the lower opening 210 of the main body 110. The lower part 202 may optionally include a lip.

[0071] Reference Figures 5 to 7 The lower sidewall 206 terminates at the top of the lower portion 202 of the main body 110, at an inclined step 218. The inclined step 218 is generally flat and slopes upward from the front portion 220 of the main body 110 to the rear portion 222 of the main body 110. Figure 5 and Figure 6 As shown, the upper portion 204 of the main body 110 extends upward from the inclined step 218. In particular, the upper portion 204 of the main body 110 includes an outer wall 240 that tapers towards the longitudinal axis A (see Figure 118). Figure 7 ) and the inner wall 242, which is generally parallel to the longitudinal axis A (see Figure 8 The outer wall 240 and the inner wall 242 are connected at the top wall 246, which defines the top edge 248 of the body 110. (See image) Figure 10 As shown, the upper part 204 of the main body 110 defines the upper opening 250 of the main body 110, and the upper opening 250 communicates with the lower opening 210 of the main body 110.

[0072] Refer again Figures 5 to 7 The upper portion 204 of the body 110 includes a window 256 extending therein. Specifically, the window 256 extends through the outer wall 240 and inner wall 242 of the upper portion 204 and defines a window sidewall 258. The window 256 provides an opening through which the first nozzle 120 and the second nozzle 122 extend. It is contemplated that the window 256 can include any type of shape or configuration such that the nozzles 120, 122 can extend through the upper portion 204 of the body 110. Figure 7 and Figure 9 As shown, the body 110 also includes a horn 264 extending outward from the upper portion 204 away from the longitudinal axis A. The horn 264 is generally hourglass-shaped and surrounds the first nozzle 120 and the second nozzle 122. The horn 264 further surrounds the window 256 in the upper portion 204 of the body 110. In a preferred embodiment, the horn 264 is configured to capture any fluid that may drip from the nozzles 120, 122 during operation of the outer cover assembly 102. Figure 7 As shown, the angular member 264 is connected to the inclined step 218 at the lower part. In an alternative embodiment, the angular member 264 may include any shape or size. For example, the angular member 264 may include a circle, square, or triangle, rather than having an hourglass configuration.

[0073] Still refer to Figures 5 to 7 The top wall 246 of the main body 110 is recessed above the window 256. Specifically, the top wall 246 is flush with the top 266 of the angular member 264. Figure 5 and Figure 6 As shown, the top 266 of the corner 264 includes a spray indicator 268, which, once the start button 112 is pressed, indicates to the user the direction of aerosol spraying. The spray indicator 268 may extend onto a portion of the top wall 246. In an alternative embodiment, the top 266 of the corner 264 may not include the spray indicator 268. Furthermore, it is contemplated that the spray indicator 268 may be of any shape, size, or type of indicator to provide guidance to the user when operating the outer cover assembly 102.

[0074] Reference Figure 5 and Figure 6 The start button 112 is positioned in the upper opening 250 of the body 110. Specifically, the start button 112 is surrounded by the inner wall 242 of the upper portion 204 and a recessed lip 280 in the rear portion 222 of the body 110. The start button 112 is pressably connected to the body 110, allowing it to be activated from a first position or a non-activated state (see [link]). Figure 14 Move to the second position or start state (see...) Figure 26 In a preferred embodiment, the start button 112 is integrally connected to or attached to the body 110. In other words, in some embodiments, the start button 112 is integrally formed with or molded with the body 110. However, in alternative embodiments, the start button 112 may be separate from or independent of the body 110. In a preferred embodiment, the body 110 and the start button 112 are molded together during an injection molding operation.

[0075] Still refer to Figure 5 and Figure 6 The start button 112 includes a starter body 302, which has a generally elongated elliptical shape. The shape of the starter body 302 is generally similar to the shape of the upper opening 250 of the body 110 (see [reference]). Figure 10 The starter body 302 includes an upper wall 304 and side walls 306 extending around the upper wall 304. The side walls 306 gradually move away from the longitudinal axis A on both sides of the start button 112 (see...). Figure 10 The side wall 306 is generally parallel to the longitudinal axis A on the rear side of the start button 112 (see...). Figure 14 ).like Figure 7 and Figure 8 As shown, the upper wall 304 of the start button 112 is generally flat and orthogonal to the longitudinal axis A.

[0076] Still refer to Figure 5 and Figure 6The upper wall 304 connects to the rounded corner wall 310, which connects the upper wall 304 to the side wall 306 near the rear portion 222 of the body 110. A landing area 314 is positioned on the upper wall 304 and the rounded corner wall 310. More specifically, the landing area 314 extends into the starter body 110 of the start button 112 and is rounded or bowl-shaped. In a preferred embodiment, the landing area 314 includes a plurality of grip features 316 extending outwardly from the landing area 314. The landing area 314 provides the user with visual cues indicating where to place their fingers when operating the outer cover assembly 102. Furthermore, the landing area 314 is also designed to position the user's fingers on the centerline of the start button 112, wherein... Figure 14 The cross-sectional view defines the centerline of the start button 112 of the outer cover assembly 102. This allows for easier (consumer-friendly) activation of the start button 112. Multiple grip features 316 provide additional grip to the landing area 314, preventing the user's fingers from slipping when activating the start button 112. In some embodiments, the start button 112 may not include the landing area 314. Instead, the upper wall 304 of the start button 112 may be substantially flat and uninterrupted.

[0077] Reference Figure 7 The first nozzle 120 and the second nozzle 122 extend laterally outward from the start button 112, orthogonal to the longitudinal axis A. In a preferred embodiment, the first nozzle 120 and the second nozzle 122 are integrally connected to the start button 112. As will be discussed in further detail herein, the start button 112 defines a fluid passage 330 extending therein, allowing fluid from the container 104 to flow through the start button 112 and exit through the first discharge port 130 and the second discharge port 132, respectively (see...). Figure 4 Therefore, the first nozzle 120 and the second nozzle 122 define portions of the fluid passage 330 extending through the start button 112. Figure 7 and Figure 14 As shown, the start button 112 includes a bridge-like structure 336 extending outward from the longitudinal axis A and connecting the start button 112 to the body 110 at a pivot point 338. As will become more apparent as this is discussed further herein, the start button 112, about the pivot point 338, is positioned relative to the body 110 from a non-starting state (see [link to document]). Figure 14 ) translate and / or pivot to the start-up state (see Figure 26 That is, the bridge-like structure 336 and the pivot point 338 form a living hinge. For example... Figure 7 and Figure 14 As further shown, the bridge-like structure 336 includes a generally concave geometry (see [reference]). Figure 7The recessed geometry of the bridge-like structure 336 helps limit lateral movement during the activation of the start button 112 and allows the start button 112 to be more easily returned to the unactivated state (see [link]). Figure 14 Press to start (see) Figure 26 In an alternative embodiment, the bridge 336 may be more rounded than shown in the figure, or it may be substantially flat, i.e., not recessed.

[0078] Reference Figure 7 and Figure 14 The start button 112 includes a gusset 342 extending between the first nozzle 120 and the second nozzle 122 and between the second nozzle 122 and the bridge 336. The gusset 342 extends from the starter body 302 along the first nozzle 120 and the second nozzle 122. In a preferred embodiment, the gusset 342 provides additional support and stability for the start button 112 and the first nozzle 120 and the second nozzle 122. In particular, the gusset 342 helps to prevent the first nozzle 120 and the second nozzle 122 from deflecting under torque, i.e., when the start button 112 is activated. Specifically, during use of the outer cover assembly 102, the gusset 342 keeps the first nozzle 120 and the second nozzle 122 aligned and parallel to each other. Therefore, the gusset 342 limits the nozzles from deflecting when the user presses the start button 112. In some embodiments, the start button 112 may not include the gusset 342. In other embodiments, the gusset 342 may be larger or smaller than shown in the figure (see Figure 102). Figure 27 and Figure 32 ).

[0079] Transformation parameter Figures 11 to 13 The lower opening 210 of the body 110 is shown positioned adjacent to the lower edge 208 for receiving a portion of the container 104 (see [reference]). Figure 4 ). For example in Figures 11 to 14 As best viewed from the center, the body 110 includes a plurality of inwardly projecting guide ribs 350 disposed along the inner surface 352 of the body 110. The guide ribs 350 are radially spaced from each other and extend inwardly and upwardly from the lower sidewall 206 of the lower portion 202 of the body 110 along the inner surface 352 to the upper portion 204 of the body 110. Figure 11 and Figure 12 As shown, some guide ribs 350a extend inward along the inclined step 218 and upward into the upper part of the body 110. However, as Figure 13 As shown, some guide ribs 350b extend only on the lower sidewall 206 of the lower portion 202 of the body 110. In this case, the guide ribs 350b have a generally rectangular shape and terminate before the recessed lip 280.

[0080] Reference Figure 12Two guide ribs 350c extend along the inner surface 352 of the body 110 through the window 256. Specifically, the two guide ribs 350c form window sidewalls 258 in the upper part 204 of the body 110. Figures 12 to 14 As shown, the lower surface 354 of each guide rib 350 is depicted, wherein such lower surface 354 is fashioned to engage with the edge 168 of the container 104 when the outer cover assembly 102 is attached thereto (see...). Figure 4 It is conceivable that the guide rib 350 can include any type of shape and can extend along the inner surface 352 of the body 110 to any height. In some embodiments, the body 110 may include more or fewer guide ribs 350 than shown in the figure (see Figure 110). Figure 30 and Figure 40 ).like Figures 11 to 13 As shown, the body 110 and the start button 112 include multiple support ribs 360. The support ribs 360 provide additional support and structural integrity to the outer cover assembly 102. It is conceivable that the outer cover assembly 102 may include more or fewer support ribs 360, depending on the type of materials used, the intended use of the outer cover assembly 102, and the operational performance required by the user. Figures 11 to 13 As further shown, the inlet 370 of the vertical conduit 380 of the start button 112 extends to engage with the valve stem 184, resulting in fluid connection between the start button 112 and the container 104 (see [link]). Figure 4 During operation, the vertical conduit 380 is configured to receive fluid when the start button 112 is pressed (see [link]). Figure 26 ).

[0081] Reference Figures 12 to 14 Multiple equidistant fastening protrusions 386 are circumferentially arranged around the inner surface 388 of the lower sidewall 206 and are adapted to fasten the outer cover assembly 102 to the container 104 and / or allow for variations in container size for use with the outer cover assembly 102 (see [link to documentation]). Figure 4 In a preferred embodiment, the protrusion 386 forms a light interface with the groove 164 of the adjacent edge 168 of the container 104, thus limiting the rotation of the body 110 relative to the container 104 (see [link]). Figure 4 When a container with a larger diameter, that is, a container with a diameter substantially similar to that of the body 110, is inserted into the body 110 of the outer cover assembly 102, the protrusion 386 can also relieve pressure on the lower sidewall 206 of the lower part 202 of the body 110.

[0082] like Figure 3 and Figure 4Ideally, when the outer cap assembly 102 is placed onto the container 104, the fastening protrusion 386 is adaptively secured within the recess 164 in a snap-fit ​​manner. Any number and size of protrusions 386 may be included on the inner surface 388 of the outer lower sidewall 206 to aid in attaching the outer cap assembly 102 to the container 104. Alternatively, other methods known in the art may be used to fasten the outer cap assembly 102 to the container 104. Additional stabilizing ribs (not shown) and / or additional fastening protrusions 386 may also provide additional structural integrity and / or alignment assistance to ensure that the outer cap assembly 102 can be securely secured. This alignment assistance helps ensure that the start button 112 is correctly positioned on the valve stem 184.

[0083] Reference Figure 14 and Figure 15 The vertical conduit 380 of the start button 112 includes a length L1 (see...). Figure 15 The vertical conduit 380 is shown extending upward along the longitudinal axis A toward the upper wall 304 of the start button 112. As described above, the vertical conduit 380 is configured to receive fluid when the start button is pressed. Figure 15 As shown, the vertical conduit 380 intersects with the first horizontal conduit 402 and the second horizontal conduit 404 at two separate locations. The first horizontal conduit 402 and the second horizontal conduit 404 extend laterally from the vertical conduit 380 and the longitudinal axis A and / or are orthogonal to the vertical conduit 380 and the longitudinal axis A. Specifically, the first horizontal conduit 402 and the second horizontal conduit 404 are in fluid communication with the vertical conduit 380, and the first horizontal conduit 402 is located above, spaced from, and parallel to the second horizontal conduit 404. Figure 14 and Figure 15 As shown, a first horizontal conduit 402 defines a portion of a first nozzle 120, while a second horizontal conduit 404 defines a portion of a second nozzle 122. The first horizontal conduit 402 and the second horizontal conduit 404 extend from the vertical conduit 380 toward a first discharge port 130 and a second discharge port 132, respectively. Therefore, the first discharge port 130 defines a portion of the first horizontal conduit 402, and the second discharge port 132 defines a portion of the second horizontal conduit 404. Furthermore, the vertical conduit 380, the first horizontal conduit 402, and the second horizontal conduit 404 collectively define a fluid passage 330 for the start button 112.

[0084] Refer again Figure 15 The first horizontal catheter 402 defines a longitudinal axis C1 orthogonal to the longitudinal axis A, and the first horizontal catheter 402 defines a length L2. The second horizontal catheter 404 also defines a longitudinal axis C2 orthogonal to the longitudinal axis A, and the second horizontal catheter 404 also defines a length L3. Figure 15As shown, longitudinal axis C1 is parallel to longitudinal axis C2, and the length L2 of the first horizontal conduit 402 is equal to the length L3 of the second horizontal conduit 404. In an alternative embodiment, the first horizontal conduit 402 may include a length L2 that is larger or smaller than that of the second horizontal conduit 404. Figure 15 As further shown, the length L2 of the first horizontal conduit 402 and the length L3 of the second horizontal conduit 404 are both greater than the length L1 of the vertical conduit 380. However, in an alternative embodiment, the length L1 of the vertical conduit 380 may be greater than the length L2 of the first horizontal conduit 402 and / or the length L3 of the second horizontal conduit 404. In a preferred embodiment, the length L1 of the vertical conduit 380 may be between about 0.3 inches (7.6 mm) and about 1.5 inches (38.1 mm), the length L2 of the first horizontal conduit 402 may be equal to the length L1, and at most 2.0 times the length L1, i.e., between about 0.3 inches (7.6 mm) and about 3.0 inches (76.2 mm), and the length L3 of the second horizontal conduit 404 may be equal to the length L1, and at most 2.0 times the length L1, i.e., between about 0.3 inches (7.6 mm) and about 3.0 inches (76.2 mm). It is conceivable that lengths L1, L2, and L3 can include any length, such that the outer cover assembly 102 can affect the aforementioned spray output.

[0085] Still refer to Figure 15 The first horizontal conduit 402 extends through the start button 112 and is surrounded by the first inner cylindrical wall 408. (As...) Figure 15 As shown, a first inner cylindrical wall 408 extends substantially parallel to the longitudinal axis C1 from the starter body 302 of the starter button 112 to a first inner distal end 410 at the first discharge port 130. The first inner distal end 410 defines the outermost portion of the first inner cylindrical wall 408 (remote to the longitudinal axis A). In particular, the first inner distal end 410 defines the first discharge port 130. As noted herein, the first inner cylindrical wall 408 also defines a portion of the first horizontal conduit 402. Figure 15As further shown, a first outer cylindrical wall 416 is spaced apart from and surrounds a first inner cylindrical wall 408. The first outer cylindrical wall 416 also extends substantially parallel to the longitudinal axis C1 from the starter body 302 of the start button 112 to a first outer distal end 418 adjacent to the first discharge port 130. The first outer distal end 418 defines the outermost portion of the first outer cylindrical wall 416 (away from the longitudinal axis A). A first internal space 420 is defined between the first outer cylindrical wall 416 and the first inner cylindrical wall 408. The first internal space 420 includes a generally annular shape and extends within the first outer cylindrical wall 416, completely surrounding the first inner cylindrical wall 408. Therefore, the first internal space 420 can be configured to capture any liquid that may drip or spill from the first discharge port 130. In some embodiments, the first internal space 420 may not be annular and may not extend completely around the first inner cylindrical wall 408. Therefore, it is conceivable that the first interior space 420 may include any shape or configuration surrounding or partially surrounding the first inner cylindrical wall 408, provided that a portion of the first interior space 420 is provided to capture any liquid that may drip or spill from the first discharge port 130. As further noted herein, the first horizontal conduit 402, the first inner cylindrical wall 408, the first outer cylindrical wall 416, and the first discharge port 130 define the first nozzle 120.

[0086] Refer again Figure 15 The second horizontal conduit 404, positioned below the first horizontal conduit 402, extends through the start button 112 and is surrounded by the second inner cylindrical wall 430. (As...) Figure 15 As shown, the second inner cylindrical wall 430 extends substantially parallel to the longitudinal axis C2 from the starter body 302 of the starter button 112 to a second inner distal end 432 at the second discharge port 132. The second inner distal end 432 defines the outermost portion of the second inner cylindrical wall 430 (away from the longitudinal axis A). In particular, the second inner distal end 432 defines the second discharge port 132. As noted herein, the second inner cylindrical wall 430 also defines a portion of the second horizontal conduit 404. Figure 15As further shown, the second outer cylindrical wall 438 is spaced apart from and surrounds the second inner cylindrical wall 430. The second outer cylindrical wall 438 also extends substantially parallel to the longitudinal axis C2 from the starter body 302 of the start button 112 to a second outer distal end 440 adjacent to the second discharge port 132. The second outer distal end 440 defines the outermost portion of the second outer cylindrical wall 438 (away from the longitudinal axis A). A second internal space 446 is defined between the second outer cylindrical wall 438 and the second inner cylindrical wall 430. The second internal space 446 includes a generally annular shape and extends within the second outer cylindrical wall 438, completely surrounding the second inner cylindrical wall 430. Similar to the first internal space 420, the second internal space 446 can be configured to capture any liquid that may drip or spill from the second discharge port 132. In some embodiments, the second internal space 446 may not be annular and may not extend completely around the second inner cylindrical wall 430. Therefore, it is conceivable that the second internal space 446 may include any shape or configuration surrounding or partially surrounding the second inner cylindrical wall 430, provided that a portion of the second internal space 446 is provided to capture any liquid that may drip or overflow from the second discharge port 132. As further noted herein, the second horizontal conduit 404, the second inner cylindrical wall 430, the second outer cylindrical wall 438, and the second discharge port 132 define the second nozzle 122.

[0087] Reference Figure 7 and Figure 15 Multiple ribs 450 extend between the first outer cylindrical wall 416 and the second outer cylindrical wall 438, and between the first inner cylindrical wall 408 and the second inner cylindrical wall 430, respectively. In particular, the ribs 450 provide additional support for the first nozzle 120 and the second nozzle 122. Figure 7 As shown, ribs 450 are disposed in the first internal space 420 and the second internal space 446. Specifically, each nozzle 120, 122 includes four ribs 450 on each side of the first inner cylindrical wall 408 and the second inner cylindrical wall 430, namely the top, bottom, right side, and left side. Figure 15 As shown, the rib 450 tapers gradually toward the longitudinal axes C1 and C2 as it extends from the starter body 302 toward the first discharge port 130 and the second discharge port 132. In an alternative embodiment, each of the nozzles 120, 122 may include more or fewer ribs 450.

[0088] Still refer to Figure 15The first inner cylindrical wall 408 and the second inner cylindrical wall 430, as well as the first outer cylindrical wall 416 and the second outer cylindrical wall 438, respectively facilitate the reinforcement of the first nozzle 120 and the second nozzle 122 with ribs. In particular, the first inner cylindrical wall 408 and the second inner cylindrical wall 430, as well as the first outer cylindrical wall 416 and the second outer cylindrical wall 438, allow the first nozzle 120 and the second nozzle 122 to be double-walled. This double-wall configuration provides additional support to the first nozzle 120 and the second nozzle 122, thus limiting their deformation. Furthermore, the double-wall configuration also limits the warping of the first nozzle 120 and the second nozzle 122, thereby limiting collisions in their spray paths. Moreover, in addition to providing structural support for the first nozzle 120 and the second nozzle 122, the double-wall configuration also provides the user with a unique visual cue and a recognizable appearance. Specifically, the double-wall configuration of the first nozzle 120 and the second nozzle 122 draws the user’s attention to the geometry of the first discharge port 130 and the second discharge port 132 in the first nozzle 120 and the second nozzle 122.

[0089] Reference Figures 15 to 17 The first discharge port 130 and the second discharge port 132 are shown as having spherical openings inclined relative to the longitudinal axes C1 and C2, respectively. Specifically, the first discharge port 130 is configured to guide fluid from the container 104 in an upward direction relative to the longitudinal axis C1, while the second discharge port 132 is configured to guide fluid from the container 104 in a downward direction relative to the longitudinal axis C2 (see [link to relevant documentation]). Figure 15 In other words, the geometry of the first discharge port 130 and the second discharge port 132 is 180° opposite each other in vertical orientation.

[0090] Reference Figure 15 The first discharge hole 130 and the second discharge hole 132 are not perpendicular to and at right angles to the longitudinal axes C1 and C2. Instead, the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 are spherically cut or truncated at angles perpendicular to the longitudinal axes C1 and C2, i.e., not parallel to the longitudinal axis A. In particular, portions of the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 form curved surfaces or arcs therein (see...). Figures 16 to 19Because the first inner distal ends 410 and 432 of the first nozzle 120 and the second nozzle 122 are spherically cut at an angle relative to the longitudinal axes C1 and C2, the fluid from the container 104 can be directed in directions diverging from each other. The oblique spherical cut defining the first discharge port 130 and the second discharge port 132 allows the fluid to travel further from the outer cover assembly 102 and produce a larger spray pattern or profile on the target. Therefore, the first nozzle 120 and the second nozzle 122 allow the user to aim less precisely at the outer cover assembly 102, i.e., the outer cover assembly 102 produces a larger and farther moving fluid imprint on the target area. Moreover, the spherical geometry on the first discharge port 130 and the second discharge port 132 allows the fluid to flow better as it exits the first discharge port 130 and the second discharge port 132. Specifically, the spherical geometry on the first discharge port 130 and the second discharge port 132 restricts fluid flow impact and provides better fluid atomization.

[0091] Reference Figure 18 The first inner distal end 410 of the first inner cylindrical wall 408, defining the first discharge orifice 130, is shown as having a spherical opening inclined upward relative to the longitudinal axis C1. Specifically, the first inner cylindrical wall 408 extends further below the longitudinal axis C1 than above it. Therefore, fluid moving through the first nozzle 120 can be guided upward at an angle relative to the longitudinal axis C1. Since the first inner distal end 410 of the first inner cylindrical wall 408 is configured to guide fluid upward, the first outer distal end 418 of the first outer cylindrical wall 416 is also cut at a similar angle relative to the longitudinal axis C1, as the first inner distal end 410. In particular, the first outer cylindrical wall 416 is complementary to the first inner cylindrical wall 408, such that there is no (or substantially no) flow impact during the activation of the outer cover assembly 102. Therefore, the top portion 470 of the first outer distal end 418 is vertically positioned or aligned above the top portion 472 of the first inner distal end 410 (see...). Figure 15 As noted herein, the top portion 472 of the first inner distal end 410 and the top portion 470 of the first outer distal end 418 respectively define points or portions of the first inner distal end 410 and the first outer distal end 418 that extend least in the horizontal direction (away from the longitudinal axis A), such as Figure 15 As shown in the diagram. Therefore, the flow rate exiting from the first discharge port 130 will not be captured by the first outer cylindrical wall 416 or the first inner cylindrical wall 408. In some embodiments, the top portion 470 of the first outer distal end 418 may not be as... Figure 15 As shown, it extends that far. Therefore, it is conceivable that the first inner cylindrical wall 408 and the first outer cylindrical wall 416 can extend horizontally from the longitudinal axis A to any length (see Figure 1). Figure 15For example, in some embodiments, the first inner cylindrical wall 408 may extend further in the horizontal direction (away from the longitudinal axis A) than the first outer cylindrical wall 416. Furthermore, in alternative embodiments, the first outer distal end 418 of the first outer cylindrical wall 416 may include multiple segments or portions of different lengths from the longitudinal axis A. For example, the top and bottom portions of the first outer distal end 418 (relative to the longitudinal axis C1) may extend horizontally from the longitudinal axis A to one location, while the sides of the first outer distal end 418 may extend horizontally from the longitudinal axis A to different locations.

[0092] Reference Figure 19 The second inner distal end 432 of the second inner cylindrical wall 430, defining the second discharge orifice 132, is shown having a spherical opening that is inclined downward relative to the longitudinal axis C2. Specifically, the second inner cylindrical wall 430 extends further above the longitudinal axis C2 than below it. Therefore, fluid moving through the second nozzle 122 can be guided downward at an angle relative to the longitudinal axis C2. Since the second inner distal end 432 of the second inner cylindrical wall 430 is configured to guide fluid downward, the second outer distal end 440 of the second outer cylindrical wall 438 is also cut at a similar angle relative to the longitudinal axis C2, as the second inner distal end 432. In particular, the second outer cylindrical wall 438 is complementary to the second inner cylindrical wall 430, so that there is no (or substantially no) flow impingement during the activation of the outer cover assembly 102. Therefore, the bottom portion 480 of the second outer distal end 440 is vertically positioned or aligned below the bottom portion 482 of the second inner distal end 432 (see...). Figure 15 As noted herein, the bottom portion 482 of the second inner distal end 432 and the bottom portion 480 of the second outer distal end 440 respectively define points or portions of the second inner distal end 432 and the second outer distal end 440 that extend least in the horizontal direction (away from the longitudinal axis A), such as Figure 15 As shown in the diagram. Therefore, the flow rate exiting from the second discharge port 132 will not be captured by the second outer cylindrical wall 438 or the second inner cylindrical wall 430. In some embodiments, the bottom portion 480 of the second outer distal end 440 may not be as... Figure 15 As shown, it extends that far. Therefore, it is conceivable that the second inner cylindrical wall 430 and the second outer cylindrical wall 438 can extend horizontally from the longitudinal axis A to any length (see Figure 1). Figure 15For example, in some embodiments, the second inner cylindrical wall 430 may extend further in the horizontal direction (away from the longitudinal axis A) than the second outer cylindrical wall 438. Furthermore, in alternative embodiments, the second outer distal end 440 of the second outer cylindrical wall 438 may include multiple segments or portions of different lengths from the longitudinal axis A. For example, the top and bottom portions of the second outer distal end 440 (relative to the longitudinal axis C2) may extend horizontally from the longitudinal axis A to one location, while the sides of the second outer distal end 440 may extend horizontally from the longitudinal axis A to different locations.

[0093] Reference Figures 15 to 19The first discharge port 130 and the second discharge port 132 are shown as being spherically cut at an angle relative to the longitudinal axes C1 and C2. As noted herein, a spherical cut refers to any type of cut / notch where portions of the first inner distal end 410 of the first inner cylindrical wall 408 and / or the second inner distal end 432 of the second inner cylindrical wall 430 are defined by curved or arc-shaped surfaces forming an arc. However, in some embodiments, the first discharge port 130 and the second discharge port 132 may include any type of geometric cut. In particular, the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 may include any type of spherical, ball-shaped, curved, or oblique cut, thereby directing fluid from the container 104 in different or divergent directions. For example, in some embodiments, the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 may include a straight oblique cut instead of a spherical cut. Furthermore, in other embodiments, the first nozzle 120 may include one type of cut, such as a ball cut, while the second nozzle 122 may include a different type of cut, such as a straight oblique cut. Additionally, in some embodiments, the first inner distal end 410 of the first inner cylindrical wall 408 defining the first discharge orifice 130 and the second inner distal end 432 of the second inner cylindrical wall 430 defining the second discharge orifice 132 may include a radial spray pattern rather than an oblique pattern. In other embodiments, the first inner distal end 410 of the first inner cylindrical wall 408 and / or the second inner distal end 432 of the second inner cylindrical wall 430 may include one or more surfaces or portions having a combination of curved and straight cuts. Therefore, it is contemplated that the first nozzle 120 and the second nozzle 122 may include any type of geometric oblique or radial cut. Furthermore, it is also contemplated that the first nozzle 120 and the second nozzle 122 may have straight cuts orthogonal to the longitudinal axes C1 and C2. As described above, in some embodiments, the outer cover assembly 102 may include a third nozzle that extends between and aligns with the first nozzle 120 and the second nozzle 122 (vertically aligned, i.e., perpendicularly aligned with them along the longitudinal axis A). The third nozzle may be identical to the first nozzle 120 and / or the second nozzle 122. In some embodiments, the third nozzle may be identical to the first nozzle 120 and / or the second nozzle 122, except for the discharge orifice. For example, the discharge orifice of the third nozzle may include a straight cut that is orthogonal to the longitudinal axis of the third nozzle, i.e., substantially parallel to the longitudinal axis A and / or substantially orthogonal to the longitudinal axes C1 and C2, rather than being obliquely spherically cut as in the first discharge orifice 130 and the second discharge orifice 132. Thus, in use, the first nozzle 120 and the second nozzle 122 will spray fluid moving through the outer cover assembly 102 in a divergent direction, while the third nozzle will spray fluid moving through the outer cover assembly 102 in a substantially straight direction.It is conceivable that the third nozzle can guide fluid in a direction similar to or different from that of the first nozzle 120 and / or the second nozzle 122. In some embodiments, the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 may include rounded lips.

[0094] As will be discussed in further detail herein, the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 can be cut at any angle relative to the longitudinal axes C1 and C2. Therefore, it is conceivable that the first discharge port 130 and the second discharge port 132 can direct fluid in any direction. It is further conceivable that the first discharge port 130 and the second discharge port 132 can direct fluid in the same direction, in a converging direction, in a diverging direction, or a combination thereof.

[0095] Reference Figures 20 to 22 The computational fluid dynamics model of the fluid passage 330 with different inclinations of the first discharge port 130 and the second discharge port 132 is shown. Specifically, each figure shows the direction in which the fluid exits the first discharge port 130 and the second discharge port 132, depending on the angle cut at the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430. As noted herein, angle Θ represents the cutting angle relative to the longitudinal axes C1 and C2. In particular, when from... Figure 21 and Figure 22 When viewed in cross-sectional view, angle Θ is measured from the longitudinal axes C1 and C2 to the topmost edge of the first inner distal end 410 (relative to the longitudinal axis C1) and the bottommost edge of the second inner distal end 432 (relative to the longitudinal axis C2). Furthermore, angle Φ represents the angle between the fluid flowing from the first nozzle 120 and the fluid flowing from the second nozzle 122. It will be apparent to those skilled in the art that... Figures 20 to 22 The computational fluid dynamics model shown illustrates the flow angle of the fluid immediately outside the first nozzle 120 and the second nozzle 122 before it diffuses into the atmosphere.

[0096] Reference Figure 20 The angle Θ is approximately 90°, meaning that the first discharge port 130 and the second discharge port 132 are perpendicular to and at right angles to the longitudinal axes C1 and C2. Therefore, the angle Φ between the fluid leaving the first nozzle 120 and the second nozzle 122 is 0° because the first discharge port 130 and the second discharge port 132 are not at an angle. Figure 20 The flow of fluid in a typical dual-nozzle configuration is shown.

[0097] Reference Figure 21The angle Θ is approximately 130°, meaning that the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 are spherically cut at an angle of approximately 130°. Therefore, the angle Φ between the fluid exiting the first nozzle 120 and the second nozzle 122 is approximately 11°. As noted herein, Figure 1 , Figures 3 to 19 as well as Figure 26 The angles Θ of the first discharge port 130 and the second discharge port 132 of the outer cover assembly 102 shown are approximately 130° relative to the longitudinal axes C1 and C2, respectively. However, in some embodiments, the angle Θ may be between approximately 90° and approximately 170°, or between approximately 100° and approximately 160°, or between approximately 110° and approximately 150°, or approximately 130°, or at least 90°, or at least 100°, or at least 110°, or at least 130°, or at least 150°. In a preferred embodiment, the angle Θ is between approximately 90° and approximately 150°.

[0098] Reference Figure 22 The angle Θ is approximately 140°, meaning that the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 are spherically cut at an angle of approximately 140°. Therefore, the angle Φ between the fluid exiting the first nozzle 120 and the second nozzle 122 is approximately 13°. Thus, depending on the angle Θ used, the angle Φ between the fluid exiting the first nozzle 120 and the second nozzle 122 can be varied accordingly. In some embodiments, the angle Φ can be between approximately 1° and approximately 80°, or between approximately 3° and approximately 40°, or between approximately 5° and approximately 20°, or between approximately 9° and approximately 15°, or at least 1°, or at least 3°, or at least 5°, or at least 9°, or at least 15°, or at least 20°. However, in a preferred embodiment, the angle Φ is between approximately 9° and 15°.

[0099] As further noted herein, the angle of the second discharge port 132 will be opposite to the angle Θ of the first discharge port 130. For example, Figure 21 The angle Θ of the first discharge hole 130° is approximately 130° above the longitudinal axis C1, while Figure 21 The angle Θ of the second discharge hole 132 is approximately 130° below the longitudinal axis C2. As described above, it is conceivable that the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 can be cut at any angle relative to the longitudinal axes C1 and C2 to form the first discharge hole 130 and the second discharge hole 132, thereby directing the fluid flowing out of the first discharge hole 130 and the second discharge hole 132 in different or divergent directions.

[0100] Reference Figures 23 to 25The pressure profiles of the fluid at the first discharge port 130 and the second discharge port 132 are shown during the activation of the outer cover assembly 102. Specifically, Figure 23 The pressure profiles of the first discharge port 130 and the second discharge port 132 are shown when the angle Θ is approximately 90°, i.e., the first inner distal end 410 of the first inner cylindrical wall 408 and the second inner distal end 432 of the second inner cylindrical wall 430 are orthogonally cut to the longitudinal axes C1 and C2 (see [reference]). Figure 20 ).like Figure 23 As shown, the pressure profile is symmetrical (or substantially symmetrical) around the center of the first discharge port 130 and the second discharge port 132. As noted herein, Figures 23 to 25 The pressure profiles of the fluid at the first discharge port 130 and the second discharge port 132 before reaching the atmosphere are shown.

[0101] Reference Figure 24 The angle Θ between the first discharge port 130 and the second discharge port 132 is approximately 130° (see [reference]). Figure 21 Therefore, the fluid pressure near the bottom portion 486 of the first horizontal conduit 402 is higher than that near the top portion 488 of the first horizontal conduit 402. Furthermore, the fluid pressure near the top portion 490 of the second horizontal conduit 404 is higher than that near the bottom portion 492 of the second horizontal conduit 404. Therefore, the pressure profile of the fluid flowing out from the inclined first discharge port 130 and second discharge port 132 (see...) Figure 24 The pressure profile of the fluid flowing out from the non-inclined first discharge port 130 and the second discharge port 132 (see...) Figure 23 The differences are as follows. In particular, when Θ equals 90°, the pressure profile or gradient of the fluid conforms to the shape of the first discharge port 130 and the second discharge port 132 (see...). Figure 23 In other words, when Θ equals 90°, the fluid profile exhibits a circular and uniform pressure distribution around the centers of the first discharge port 130 and the second discharge port 132 (see...). Figure 23 Alternatively, when Θ is greater than 90°, the pressure profile or gradient of the fluid is asymmetrical with the shape of the first discharge port 130 and the second discharge port 132 (see [reference]). Figure 24 and Figure 25 Therefore, as the angle Θ increases from 90°, the pressure profile of the fluid will shift away from the symmetrical gradient.

[0102] Reference Figure 25 The angle Θ between the first discharge port 130 and the second discharge port 132 is approximately 140° (see [reference]). Figure 22 Therefore, with Figure 24 similar, Figure 25 The pressure of the fluid is highest near the bottom portion 486 of the first horizontal conduit 402 or the first nozzle 120 and near the top portion 488 of the second horizontal conduit 404 or the second nozzle 122.

[0103] Reference Figures 23 to 25 The pressure profile of the fluid varies depending on the angle Θ used. Specifically, when using the spherically inclined first discharge port 130 and second discharge port 132, the fluid pressure increases at the bottom of the first horizontal conduit 402 and the top of the second horizontal conduit 404. This causes the fluid pressure gradient to change in the vertical direction (see...). Figure 24 and Figure 25 ), rather than the radial variation when the first discharge port 130 and the second discharge port 132 are not at an angle (see Figure 23 Furthermore, the spherically inclined discharge holes 130 and 132 increase the pressure on the first discharge hole 130 and the second discharge hole 132. Specifically, as... Figure 25 As shown, the pressure profiles at the first discharge port 130 and the second discharge port 132 are compared. Figure 23 The pressure profile shown increases significantly over a larger area. The larger pressure profile spanning the first discharge port 130 and the second discharge port 132 helps to better disperse the fluid into the atmosphere and create a wider and / or larger spray area. In a preferred embodiment, the first angled discharge port 130 and the second angled discharge port 132 (see...) Figure 24 and Figure 25 ) Compared to non-inclined discharge holes 130, 132 (see Figure 23 This forms a spray area that is approximately 10%-40% wider and / or larger. In some embodiments, the first inclined discharge port 130 and the second inclined discharge port 132 form a spray area that is approximately 30% wider and / or larger.

[0104] Back reference Figure 23 The fluid pressure is circumferentially uniform at each radial level of the non-inclined first discharge port 130 and second discharge port 132, meaning the pressure variation between two points on the circumference of a circle centered on the first and second discharge ports 130 and 132 will be generally zero. In other words, in the non-inclined case, the net pressure gradient on the circumference of the circle defined in the first and second discharge ports 130 and 132 (and centered on the longitudinal axes C1 and C2) will be generally zero (see...). Figure 23 Conversely, the net pressure gradient on the circumference of the circles in the inclined first discharge port 130 and second discharge port 132 (see...) Figure 24 and Figure 25 The pressure change between two points on the circumference of a circle centered on the first discharge hole 130 and the second discharge hole 132 (along the longitudinal axes C1 and C2) will not be zero. Therefore, as... Figure 24 and Figure 25As shown, when the angle Θ is greater than 90°, the pressure profiles of the first discharge port 130 and the second discharge port 132 are generally irregular. In particular, as described above, the maximum pressure is located near the bottom portion 486 of the first horizontal conduit 402 and near the top portion 490 of the second horizontal conduit 404. In some embodiments, the net pressure gradient on the circumference of a circle centered on the inclined first discharge port 130 and the second discharge port 132 (along the longitudinal axes C1, C2) can be + / - 300,000 Pa.

[0105] Reference Figures 15 to 19 as well as Figures 23 to 25 The first discharge port 130 and the second discharge port 132, as well as the first horizontal conduit 402 and the second horizontal conduit 404, have a generally circular cross-section (see [reference]). Figures 23 to 25 However, in alternative embodiments, the first discharge port 130 and the second discharge port 132, as well as the first horizontal conduit 402 and the second horizontal conduit 404, can include any type of cross-sectional profile. For example, the first discharge port 130 and the second discharge port 132, as well as the first horizontal conduit 402 and the second horizontal conduit 404, can include an hourglass profile, a square profile, a triangular profile, or any type of polygonal profile. In some embodiments, the shapes of the first discharge port 130 and the second discharge port 132, as well as the first horizontal conduit 402 and the second horizontal conduit 404, can be elliptical. Depending on the shape of the first discharge port 130 and the second discharge port 132, as well as the first horizontal conduit 402 and the second horizontal conduit 404, when the angle Θ is equal to 90°, the pressure profile of the fluid will generally conform to the shape of the first discharge port 130 and the second discharge port 132, as well as the first horizontal conduit 402 and the second horizontal conduit 404. Conversely, once the angle Θ is greater than 90°, the pressure profile of the fluid will be different.

[0106] Back reference Figure 14 and Figure 15 When the user activates the start button 112 to dispense fluid, fluid flows through the valve stem 184 (see...). Figure 4 The pressurized fluid enters the vertical conduit 380 and then the first horizontal conduit 402 and / or the second horizontal conduit 404, thereby flowing out of the outer cover assembly 102 into the surrounding atmosphere through the first discharge port 130 and the second discharge port 132. Therefore, fluid can flow from the start button 112 through either the first horizontal conduit 402 or the second horizontal conduit 404. In a preferred embodiment, the cross-sectional area of ​​the channel within the vertical conduit 380 is larger than that of the channels within the first horizontal conduit 402 and the second horizontal conduit 404, which may necessarily result in higher fluid pressures within the first and second horizontal conduits 402 and 404 during fluid dispensing. Therefore, the fluid pressure at different points along the fluid channel 330 can be adjusted based on the different cross-sectional areas of different portions of the fluid channel 330.

[0107] Still refer to Figure 14 and Figure 15 The cross-section of the channel within the first horizontal conduit 402 is the same as the cross-section of the channel within the second horizontal conduit 404. However, in alternative embodiments, the cross-section of the channel within the first horizontal conduit 402 may be smaller than the cross-section of the channel within the second horizontal conduit 404, and vice versa. Therefore, a balance can be achieved between the fluid discharge rate of the first horizontal conduit 402 and the second horizontal conduit 404. Furthermore, in some embodiments, the first horizontal conduit 402 and / or the second horizontal conduit 404 may include a blocking portion (see...). Figure 32 and Figure 43 For example, a segment of the first horizontal conduit 402 and / or the second horizontal conduit 404 may include a diameter smaller than that of different segments of the first horizontal conduit 402 and / or the second horizontal conduit 404. Variations in the cross-sectional area and dimensions of the channels of the first horizontal conduit 402 and the second horizontal conduit 404 affect the particle droplet size of the fluid. Therefore, the first horizontal conduit 402 and the second horizontal conduit 404 can be adapted to produce an ideal fluid particle droplet size. As noted herein, the vertical conduit 380, the first horizontal conduit 402, and the second horizontal conduit 404 define the manifold 502.

[0108] Now refer to Figure 14 and Figure 26 The operation of the outer cover assembly 102 will be described in more detail. Figure 14 The image shows the non-starting configuration of the outer cover assembly 102, and Figure 26 The activation configuration is shown in the diagram. In use, by applying force to the activation button 112, the product or fluid is ejected from the dispensing system 100 (see [reference]). Figure 4 ). Reference Figure 26 , Figure 26 The image shows the outer cover assembly 102 during startup, with the vertical conduit 380 forced downwards and pressing down the valve stem 184 (see [link]). Figure 4 This allows the valve assembly to allow product or fluid to enter manifold 502. Specifically, once the user contacts the landing area 314 of the activation button 112, the activation button 112 translates and pivots about pivot point 338. In a preferred embodiment, the valve stem 184 translates from the non-activating position to the activating position between about 0.0 inch (0.0 mm) and about 0.2 inch (5.1 mm) (see [link]). Figure 4 After the force is released from the start button 112, the manifold 502 returns to the non-start position, as shown below. Figure 14 As shown. The valve assembly is closed within container 104 by the upward force of the valve stem 184 under the action of the valve spring (not shown). Figure 4 The start button 112 is moved to the non-start position.

[0109] It should also be noted that, Figure 26 The outer cover assembly 102 depicted in the activated state is shown as being in the fully activated state. However, depending on the tolerances or specific characteristics of the container and / or valve stem and accompanying valve assembly, it is possible to achieve this by pressing the activation button 112 downwards. Figure 14 (Non-boot) and Figure 26 (Full activation) Achieving a complete or partial spraying effect is achieved at a position between the two positions shown. However, to explain the function of the activation button 112 and its interaction with the body 110, [further details are needed]. Figure 26 The term "start-up state" related to the outer cover assembly 102 actually refers to the fully started state of the outer cover assembly 102.

[0110] Still refer to Figure 14 and Figure 26 When the user applies force to the landing area 314 of the start button 112 to move the start button 112 from its non-start state, the first discharge port 130 and the second discharge port 132 move from the first position to the second position. (Refer to...) Figure 14 Due to the force of the valve spring (not shown), the start button 112 remains in the non-starting state until the user presses down on the landing area 314 of the start button 112, causing the start button 112 to translate and / or rotate from the non-starting state to the starting state. Now refer to Figure 26 The start button 112 is shown to be vertically downward and rotated clockwise around pivot point 338 to the start state. As described above, the start button 112 remains in the start state until the user releases the landing area 314 of the start button 112, causing the start button 112 to move from the start state ( Figure 26 Translate and / or rotate back to the non-starting state. Figure 14 ).

[0111] Reference Figures 27 to 32 Regarding alternative embodiments, the outer cover assembly 602 uses similar reference numerals. As indicated herein, the outer cover assembly 602 is configured to attach to the container 104 (see [reference]). Figure 2 And, apart from a few differences, it is essentially similar to the outer cover assembly 102, which will be explained in detail below. Figure 27 , Figure 29 as well as Figure 32 As shown, the start button 112 of the outer cover assembly 602 includes a gusset 604 extending between the first nozzle 120 and the second nozzle 122 and between the second nozzle 122 and the bridge 336. As noted herein, the gusset 604 extends further outward from the starter body 302 than the gusset 342 (see [link to original document]). Figure 7 and Figure 14Therefore, the gusset 604 provides additional stability and support for the first nozzle 120, the second nozzle 122, and the start button 112. As described above, when the start button 112 is subjected to a torque force, for example, when a user presses the start button 112 to dispense fluid, the gusset 604 aligns and parallels the first nozzle 120 and the second nozzle 122. Therefore, each time the start button 112 is pressed, the fluid flow from the first nozzle 120 and the second nozzle 122 is consistent.

[0112] Reference Figure 27 and Figures 29 to 32 The bridge-like structure 336 includes a recessed geometry (see...). Figure 29 In alternative embodiments, the bridge 336 may include any type of geometry, such as a flat or keyway geometry. Figure 30 and Figure 31 As shown, the bridge-like structure 336 also includes a plurality of reinforcing ribs 612 on its lower side 614. The plurality of reinforcing ribs 612 extend horizontally and generally vertically along the lower side 614 of the bridge-like structure 336. The recessed geometry of the bridge-like structure 336 and the plurality of reinforcing ribs 612 help to limit lateral movement of the bridge-like structure 336 and the start button 112 during activation. Therefore, the recessed geometry of the bridge-like structure 336 and the plurality of reinforcing ribs 612 tilt the start button 112 to be closer to its centerline, wherein... Figure 32 The cross-sectional view defines the centerline of the start button 112 of the outer cover assembly 602. In some embodiments, the lower side 614 of the bridge 336 may include more or fewer reinforcing ribs 612 than shown in the figure.

[0113] Reference Figure 28 The body 110 of the outer cover assembly 602 includes a lip 620 in the rear portion 222 of the body 110. The lip 620 extends upward along the inner wall 242 of the upper portion 204 of the body 110 on both sides of the outer cover assembly 602. Specifically, the lip 620 includes a generally recessed shape extending between the two sides of the upper portion 204. A recessed wall 622 extends from the lip 620 toward the start button 112. Figure 28 As shown, the outer edge 624 of the recessed wall 622 is positioned behind the lip 620. In a preferred embodiment, the outer edge 624 of the recessed wall 622 also extends upward along the inner wall 242 of the upper portion 204 of the body 110 on both sides of the outer cover assembly 602. However, in some embodiments, the outer edge 624 may not extend upward along the inner wall 242 of the upper portion 204 of the body 110. Figure 32As shown, the recessed wall 622 extends generally straight from the lip 620 to the start button 112; however, in some embodiments, the recessed wall 622 may extend upward from the lip 620 to the start button 112 at a small angle. The lip 620 and the recessed wall 622 help provide additional structural support for the outer cover assembly 602.

[0114] Reference Figure 30 and Figure 31 The outer cover assembly 602 includes more guide ribs 350 than previously shown (see Figures 11 to 13 (Outer cover assembly 102). In particular, outer cover assembly 602 includes approximately twice as many guide ribs 350 as outer cover assembly 102. Figure 30 and Figure 31 As shown, the body 110 of the outer cover assembly 602 includes curved ribs 630 that extend along the inclined steps 218 of the body 110 through guide ribs 350a. The curved ribs 630 extend on opposite sides of the body 110 and are generally symmetrical about the centerline of the outer cover assembly 602. The additional guide ribs 350 and curved ribs 630 provide additional structural support to the outer cover assembly 602. Specifically, the additional guide ribs 350 and curved ribs 630 increase the outer cover assembly 602's ability to withstand higher top loads to meet packaging distribution requirements, i.e., the outer cover assembly 602 can be stored for longer periods without collapsing. The increased structural support also gives the outer cover assembly 602 a longer lifespan. Figure 30 As shown, the outer cover assembly 602 includes two curved ribs 630; however, in alternative embodiments, the outer cover assembly 602 may include more or fewer curved ribs 630.

[0115] Reference Figure 32 The first horizontal conduit 402 includes a blocking portion 640 adjacent to the vertical conduit 380. For example... Figure 32 As shown, the blocking portion 640 increases the diameter of the first horizontal conduit 402 from its initial diameter when connected to the vertical conduit 380. The blocking portion 640 helps balance the fluid discharge rate between the first horizontal conduit 402 and the second horizontal conduit 404. In some embodiments, the second horizontal conduit 404 may also include a blocking portion similar to the blocking portion 640 in the first horizontal conduit 402. In other embodiments, the first horizontal conduit 402 may not include the blocking portion 640. Furthermore, in some embodiments, as described above, the outer cap assembly 602 may include a third nozzle.

[0116] As noted herein, the outer cover assembly 602 functions identically to the outer cover assembly 102. Specifically, once the activation button 112 of the outer cover assembly 602 is pressed, the valve stem 184 from the container 104 (see [link to document]) activates. Figure 2 The fluid will move through fluid channel 330 (see fluid channel 330). Figure 30The fluid exits from either the first discharge port 130 or the second discharge port 132. The first discharge port 130 and the second discharge port 132 of the outer cover assembly 602 include spherical beveled cuts to direct the fluid in a divergent direction, similar to the description above regarding the outer cover assembly 102. Furthermore, the outer cover assembly 602 also includes the same manifold 502 as the outer cover assembly 102. Therefore, the outer cover assembly 602 includes the same vertical conduit 380, first horizontal conduit 402, and second horizontal conduit 404 as the outer cover assembly 102.

[0117] Reference Figures 33 to 43 Regarding another alternative embodiment, the outer cover assembly 702, similar reference numerals are used. As noted herein, the outer cover assembly 702 is configured to attach to the container 104 (see [reference needed]). Figure 2 And, apart from a few differences, it is basically similar to the outer cover components 102 and 602, which will be explained in detail below. Figure 33 , Figure 35 as well as Figure 36 As shown, the upper portion 204 of the body 110 of the outer cover assembly 702 includes a curved outer wall 704. (As...) Figure 35 As shown, the curved outer wall 704 generally bends from the inclined step 218 toward the longitudinal axis A and terminates at the top edge 248 of the body 110. When the outer cover assembly 702 is viewed from the right and left sides, the curved outer wall 704 defines a generally concave shape (see...). Figure 35 Furthermore, the curved outer wall 704 is more pronounced near the right and left sides of the body 110 than at the front 220 of the body 110 (see [reference]). Figure 33 and Figure 35 ).like Figure 36 As shown, the curved outer wall 704 also creates a smoother transition between the curved outer wall 704, the inclined step 218, and the lower part 202 of the main body 110.

[0118] Reference Figure 35 The curved outer wall 704 of the main body 110 extends further downward into the lower part 202 of the main body 110 than the outer wall 240 of the outer cover assemblies 102 and 602. Therefore, the inclined steps 218 in the outer cover assembly 702 are smaller than those in the outer cover assemblies 102 and 602, i.e., have a smaller surface area (see...). Figure 7 and Figure 29 As noted herein, the curved outer wall 704 of the body 110 of the outer cover assembly 702 increases the top load capacity of the outer cover assembly 702. Specifically, the curved outer wall 704 increases the ability of the outer cover assembly 702 to withstand higher top load forces to meet packaging distribution requirements, i.e., the outer cover assembly 702 can be stored for a longer period without collapsing. The curved outer wall 704 also allows the outer cover assembly 702 to have a longer lifespan. Figure 35 As shown, unlike outer cover assemblies 102 and 602, the corner 264 of outer cover assembly 702 is not connected to the inclined step 218. However, in some embodiments, the corner 264 of outer cover assembly 702 may include various ribs or supports connected to the inclined step 218.

[0119] Reference Figure 40 and Figure 41 The outer cover assembly 702 includes a configuration of guide ribs 350 that differs from those previously shown (see [reference]). Figures 11 to 13 The outer cover assembly 102 and Figure 30 and Figure 31 (External cover assembly 602). In particular, compared to external cover assemblies 102 and 602, external cover assembly 702 includes more guide ribs 350a and guide ribs 350b with different configurations. Furthermore, the body 110 of external cover assembly 702 includes rounded ribs 720 that extend along the inclined steps 218 of the body 110 through some of the guide ribs 350b. The rounded ribs 720 are positioned near the front portion 220 of the body 110 and form a crescent-shaped extension through two guide ribs 350c. Figure 40 As shown, the rounded corner rib 720 begins and terminates at one of the guide ribs 350b. However, in some embodiments, the rounded corner rib 720 may extend further or closer than shown in the figure.

[0120] Still refer to Figure 40 and Figure 41 The outer cover assembly 702 also includes upper wall ribs 722 located on both sides of the body 110. The upper wall ribs 722 are elongated, rounded ribs (saber-tooth shaped) extending from the lower portion of the curved outer wall 704 (adjacent to the inclined step 218) to the top wall 246 of the body 110. The upper wall ribs 722 are also connected to the inner wall 242 of the body 110. The additional guide ribs 350, rounded ribs 720, and upper wall ribs 722 provide additional structural support to the outer cover assembly 702. Specifically, the additional guide ribs 350, rounded ribs 720, and upper wall ribs 722 increase the outer cover assembly 702's ability to withstand higher top loads to meet packaging dispensing requirements and / or support the curved outer wall 704 of the body 110. In some embodiments, the body 110 of the outer cover assembly 702 may include more or fewer rounded ribs 720 and / or upper wall ribs 722 than shown in the figures. Figure 40 , Figure 41 as well as Figure 43 As shown, the outer cover assembly 702 also includes a frame-like protrusion 726 positioned between the rounded corner rib 720 and a plurality of reinforcing ribs 612 on the underside 614 of the bridge 336. The frame-like protrusion 726 extends along a path similar to that of the rounded corner rib 720.

[0121] Reference Figure 43 Similar to the outer cover assembly 602, the outer cover assembly 702 includes a blocking portion 640 within the first horizontal conduit 402 near the vertical conduit 380. As described above, the blocking portion 640 increases the diameter of the first horizontal conduit 402 from its initial diameter when connected to the vertical conduit 380. The blocking portion 640 helps balance the fluid discharge rate between the first horizontal conduit 402 and the second horizontal conduit 404. In particular, the blocking portion 640 can increase the velocity and / or pressure of the fluid extending through the first horizontal conduit 402. As noted herein, the blocking portion 640 can include any diameter gradient in the first horizontal conduit 402 to achieve desired spray characteristics. For example, in some embodiments, the blocking portion 640 can increase the diameter of the first horizontal conduit 402 by more or less than shown in the figures. Furthermore, in some embodiments, the second horizontal conduit 404 may also include a blocking portion similar to the blocking portion 640 in the first horizontal conduit 402. In other embodiments, the first horizontal conduit 402 may not include the blocking portion 640 (see [link to documentation]). Figure 14 Furthermore, in some embodiments, the first horizontal conduit 402 and / or the second horizontal conduit 404 may include a reduced-diameter obstruction, i.e., the diameter within the first horizontal conduit 402 and / or the second horizontal conduit 404 is reduced from its initial diameter. Additionally, in some embodiments, as described above, the outer cover assembly 702 may include a third nozzle.

[0122] Reference Figure 42 The first discharge port 130 and the second discharge port 132 of the outer cover assembly 702 include spherical bevel cuts that allow fluid to flow from the container 104 (see...). Figure 2 This is similar to the description above regarding outer cover assemblies 102 and 602. Furthermore, as noted herein, outer cover assembly 702 functions identically to outer cover assemblies 102 and 602. Specifically, once the activation button 112 of outer cover assembly 702 is pressed, the valve stem 184 from container 104 (see...)... Figure 2 The fluid will move through fluid channel 330 (see fluid channel 330). Figure 43 It also discharges from one of the first discharge port 130 and the second discharge port 132. Furthermore, the outer cover assembly 702 includes the same manifold 502 as the outer cover assembly 102. Therefore, the outer cover assembly 702 includes the same vertical conduit 380, first horizontal conduit 402, and second horizontal conduit 404 as the outer cover assembly 102.

[0123] As can be understood from the above, due to the spherical inclined geometry at the first discharge port 130 and the second discharge port 132, the outer cover assemblies 102, 602, and 702 allow fluid from container 104 to flow through manifold 502 and exit in a divergent direction from the first nozzle 120 and the second nozzle 122. Because the fluid exits the outer cover assemblies 102, 602, and 702 in a divergent direction, it can enter the atmosphere further from the outer cover assemblies 102 and 602, producing a larger spray profile or pattern on the target, thus allowing a larger area to receive fluid from container 104.

[0124] It is conceivable that the outer cover assemblies 102, 602, and 702 disclosed herein can be matched with containers having non-vertical valve assemblies or with valve stems requiring angular movement for actuation. Furthermore, while the teachings of the outer cover assemblies of the present invention are particularly advantageous for containers with smaller footprints, embodiments of the invention can be used with containers of any size.

[0125] Any embodiment described herein can be modified to include any structure or method disclosed in different embodiments. Furthermore, the invention is not limited to aerosol containers of the specific types shown. Additionally, the outer cap of any embodiment disclosed herein can be modified for use with any type of aerosol or non-aerosol container.
