BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to an overcap assembly including a body and an actuating button, and more particularly, to a double nozzle overcap assembly with spherical, curved, or angled exit apertures.

2. Description of the Background of the Invention

Pressurized containers are commonly used to store and dispense volatile materials, such as air fresheners, deodorants, insecticides, germicides, decongestants, perfumes, and the like. The volatile materials are typically stored in a pressurized and liquefied state within the container. The product is forced from the container through an aerosol valve by a hydrocarbon or non-hydrocarbon propellant. A release valve with an outwardly extending valve stem may be provided to facilitate the release of the volatile material at a top portion of the container, whereby activation of the valve via the valve stem causes volatile material to flow from the container through the valve stem and into the outside atmosphere. The release valve may typically be activated by tilting, depressing, or otherwise displacing the valve stem. A typical valve assembly includes a valve stem, a valve body, and a valve spring. The valve stem extends through a pedestal, wherein a distal end extends upwardly away from the pedestal and a proximal end is disposed within the valve body.

Pressurized containers frequently include an overcap assembly that covers a top end of the container. Typical overcap assemblies are releasably attached to the container by way of an outwardly protruding ridge, which circumscribes the interior lower edge of the overcap assembly and interacts with a bead or seam that circumscribes a top portion of the container. When the overcap assembly is placed onto the top portion of the container, downward pressure is applied to the overcap assembly, which causes the ridge to ride over an outer edge of the seam and lock under a ledge defined by a lower surface of the seam.

Typical overcap assemblies include a mechanism for engaging the valve stem of the container. Some actuator mechanisms may include linkages that apply downward pressure to depress the valve stem and open the valve within the container. Other actuating mechanisms may instead apply radial pressure where the container has a tilt-activated valve stem. In any case, these actuating mechanisms provide a relatively convenient and easy to use interface for end users.

Conventional actuating mechanisms include either an actuating button or an actuating trigger. Traditional actuating buttons may include a discharge orifice along a portion of the button, or at a separate location along a body or base of the overcap assembly. Regardless of the positioning of the discharge orifice, after actuation by a user, the volatile material typically travels through a fluid passageway. Portions defining the passageway typically engage the valve stem of an associated container. Thus, when dispensement is desired, a user may actuate the actuator by pressing down on it, which in turn depresses the valve stem and opens the valve within the associated container, thereby releasing the contents of the container through the fluid passageway and out of the discharge orifice.

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

Conventional overcap assemblies can include one or more nozzles extending from the actuating button. Numerous problems can arise with prior art actuation systems utilizing multiple nozzles. In particular, many prior art actuation systems with multiple nozzles extending from the actuating button have warpage or deformation along the nozzles during use. Further, prior art actuation systems with multiple nozzles include bad fluid atomization and spray paths that collide with each other or that catch an outer wall of the nozzle and flow back, pooling in an area surrounding the nozzles. Furthermore, prior art actuation systems with multiple nozzles require complex manufacturing processes requiring difficult molding operations. These and other disadvantage of the prior art are overcome by the overcap assembly described hereinafter.

SUMMARY OF THE INVENTION

According to a first aspect, an overcap assembly is configured to attach to a container. The overcap assembly includes a body, an actuator, a first nozzle, and a second nozzle. The actuator is integrally attached with the body and defines a longitudinal axis. The actuator further comprises a fluid passageway that extends therein. The first nozzle and the second nozzle extend laterally from the actuator, and the first nozzle and the second nozzle define a portion of the fluid passageway. The first nozzle comprises a first angled exit aperture and the second nozzle comprises a second angled exit aperture. The first nozzle and the second nozzle each comprise an inner cylindrical wall and an outer cylindrical wall that surrounds and is spaced apart from the inner cylindrical wall. The first angled exit aperture and the second angled exit aperture are non-parallel to the longitudinal axis.

According to some embodiments, the first angled exit aperture and the second angled exit aperture comprise a spherical opening. In some embodiments, an angle between a fluid exiting the first angled exit aperture and a fluid exiting the second angled exit aperture is between about 9° and about 15°. In some embodiments, the first nozzle and the second nozzle each comprise an interior space defined between the inner cylindrical wall and the outer cylindrical wall.

In some embodiments, the first angled exit aperture and the second angled exit aperture are configured to direct a fluid in diverging directions.

According to another aspect, an actuating button includes a vertical conduit, a first horizontal conduit, and a second horizontal conduit. The vertical conduit comprises a length L₁ and is configured to receive a fluid when the actuating button is depressed. The first horizontal conduit extends laterally from the vertical conduit. The first horizontal conduit comprises a first exit aperture and is in fluid communication with the vertical conduit. The first horizontal conduit further comprises a length L₂. The second horizontal conduit extends laterally from the vertical conduit and below the first horizontal conduit. The second horizontal conduit comprises a second exit aperture and is in fluid communication with the vertical conduit. The second horizontal conduit further comprises a length L₃.

The first exit aperture is angled between about 90° and about 170° upward relative to the first longitudinal axis, and the second exit aperture is angled between about 90° and about 170° downward relative to the second longitudinal axis. In some embodiments, the first exit aperture is configured to direct the fluid in an upward direction with respect to the first longitudinal axis, and the second exit aperture is configured to direct the fluid in a downward direction with respect to the second longitudinal axis. In some embodiments, the actuating button further comprises a first inner cylindrical wall that defines a portion of the first horizontal conduit, a first outer cylindrical wall that surrounds the first inner cylindrical wall, a second inner cylindrical wall that defines a portion of the second horizontal conduit, and a second outer cylindrical wall that surrounds the second inner cylindrical wall. A first interior space is defined between the first outer cylindrical wall and the first inner cylindrical wall. A second interior space is defined between the second outer cylindrical wall and the second inner cylindrical wall. In some embodiments, the first horizontal conduit and the second horizontal conduit extend orthogonally from the vertical conduit.

According to yet another aspect, an overcap assembly is configured to attach to a container. The overcap assembly comprises a body, an actuator, a first nozzle, and a second nozzle. The actuator is integrally attached with the body and defines a longitudinal axis. The actuator comprises a fluid passageway therein, and the fluid passageway is configured to receive a fluid when the actuator is depressed. The first nozzle extends laterally from the actuator, and the first nozzle defines a portion of the fluid passageway. The first nozzle comprises a first exit aperture. The second nozzle extends from the actuator parallel to the first nozzle, and the second nozzle defines a portion of the fluid passageway. The second nozzle comprises a second exit aperture. A pressure of the fluid at the first exit aperture when the actuator is depressed is highest near a bottom portion of the first nozzle. Further, a pressure of the fluid at the second exit aperture when the actuator is depressed is highest near a top portion of the second nozzle.

According to some embodiments, the first nozzle comprises a first horizontal conduit defining a first longitudinal axis, and the second nozzle comprises a second horizontal conduit defining a second longitudinal axis. The first exit aperture is angled relative to the first longitudinal axis, and the second exit aperture is angled relative to the second longitudinal axis.

DETAILED DESCRIPTION OF THE DRAWINGS

The term “about,” as used herein, refers to variations in the numerical quantity that may occur, for example, through typical measuring and manufacturing procedures used for product dispensing systems or other articles of manufacture that may include embodiments of the disclosure herein; through inadvertent error in these procedures; through differences in the manufacture, source, or purity of the ingredients used to make the compositions or mixtures or carry out the methods; and the like. Throughout the disclosure, the terms “about” and “approximately” refer to a range of values ±5% of the numeric value that the term precedes. Further, as noted herein, all numeric ranges disclosed within this application are inclusive of the outer bounds of the range.

FIG. 1 depicts a product dispensing system 100 including an overcap assembly 102 and a container 104. The overcap assembly 102 includes a body 110, an actuator or actuating button 112, a first nozzle 120, and a second nozzle 122. The first and the second nozzle 120, 122 extend outwardly from the actuating button 112, parallel to each other. The actuating button 112 is at least partially disposed within the body 110 and facilitates the product being dispensed from the dispensing system 100. In use, the overcap assembly 102 is adapted to release a product from the container 104 upon the occurrence of a particular condition, such as the manual depression of the actuating button 112 by a user of the dispensing system 100. The product discharged may be a formulation, carrier, or substance for use in a household, commercial, or industrial environment. The product is discharged through a first angled exit aperture 130 of the first nozzle 120 and a second angled exit aperture 132 of the second nozzle 122. It is contemplated that the overcap assembly 102 can include more or fewer nozzles than shown. For example, in one embodiment, the overcap assembly 102 may include a third nozzle extending between the first nozzle 120 and the second nozzle 122.

In some embodiments, the product comprises an insect repellant or insecticide disposed within a carrier liquid or the like. The product may also comprise other actives, such as sanitizers, air fresheners, fragrances, deodorizers, cleaners, odor eliminators, mold or mildew inhibitors, and/or the like, and/or that have aromatherapeutic properties. The product alternatively comprises any solid, liquid, or gas known to those skilled in the art that may be dispensed from a container. It is contemplated that the container 104 may contain any type of pressurized or non-pressurized product, such as compressed gas that may be liquefied, non-liquefied, or dissolved, including carbon dioxide, helium, hydrogen, neon, oxygen, xenon, nitrous oxide, or nitrogen. The container 104 may alternatively contain any type of hydrocarbon gas, including acetylene, methane, propane, butane, isobutene, halogenated hydrocarbons, ethers, mixtures of butane and propane, otherwise known as liquid petroleum gas or LPG, and/or mixtures thereof. The product dispensing system 100 is therefore adapted to dispense any number of different products.

The container 104 and/or overcap assembly 102 may each be independently made of any appropriate material, including multiple layers of the same or different material, such as a polymer, a plastic, metal such as aluminum, an aluminum alloy, or tin plated steel, glass, a cellulosic material, a laminated material, a recycled material, and/or combinations thereof. The overcap assembly 102 may be formed from a wide 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 glycol terephthalate, polystyrene (PS), polyamide (PA), polyvinyl chloride (PVC), polycarbonate (PC), poly(styrene:acrylonitrile) (SAN), polymethylmethacrylate (PMMA), polypropylene (PP), polyethylene naphthalene (PEN), polyethylene furanoate (PEF), PET homopolymers, PEN copolymers, PET/PEN resin blends, PEN homopolymers, overmolded thermoplastic elastomers (TPE), fluropolymers, polysulphones, polyimides, cellulose acetate, and/or combinations thereof. It is further envisioned that the container 104 may include an interior and/or exterior lining or coating to further strengthen the container 104 structurally, as well as make the container 104 resilient to harsh chemicals. The lining(s) and/or coating(s) may be made of any one of the preceding polymeric materials or may further be made of ethylenevinyl alcohol (EVOH). The container 104 may be opaque, translucent, or transparent.

As best illustrated in FIG. 2, the container 104 includes a lower end 160 and a substantially cylindrical body 162, which terminates at a groove 164 disposed at an upper end 166 of the container 104. The overcap assembly 102 may be attached to the container 104 via the groove 164, as discussed below (see FIG. 4). A rim 168 is disposed adjacent and above the groove 164, and joins a platform 170 that partially defines the upper end 166 of the container 104. The platform 170 is generally annular. It is contemplated that the container 104 of the present disclosure may be a conventional aerosol container, which includes features that are externally or internally crimped to portions of the cylindrical body 162 and/or the rim 168. For example, as illustrated in FIG. 2, a dome 176 may be externally crimped to the container 104 at the rim 168.

Still referring to FIG. 2, the dome 176 of the container 104 is generally spherical and extends upwardly from the platform 170. An upwardly open valve cup 178 is located at the center of the dome 176 and is crimped or otherwise joined to the dome 176 to form a valve cup rim 180. A valve pedestal 182 extends from a central portion of the valve cup 178, and includes a conventional valve assembly (not shown in detail) having a valve stem 184, which is connected to a valve body (not shown) and a valve spring (not shown) disposed within the container 104. The valve stem 184 extends upwardly through the valve cup 178, wherein a distal end 186 of the valve stem 184 extends upwardly away from the valve cup 178 and is adapted to interact with a fluid inlet of the actuating button 112 of the overcap assembly 102 (see FIG. 4). A longitudinal axis A extends through the valve stem 184. It is also contemplated that other types of containers 104 or bottles may be used with the overcap assembly 102 disclosed herein.

As best shown in FIGS. 3 and 4, prior to use, the actuating button 112 is placed in fluid communication with the distal end 186 of the valve stem 184. A user may manually or automatically actuate the actuating button 112 to open the valve assembly, which causes a pressure differential between an interior 188 of the container 104 and the atmosphere to force the contents of the container 104 out through an orifice 190 of the valve stem 184, through the overcap assembly 102, and into the atmosphere.

Now turning to FIGS. 5-10, the overcap assembly 102 is described with greater particularity. The body 110 of the overcap 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 comprises a lower sidewall 206 that extends upward along the longitudinal axis A. As previously noted, the longitudinal axis A is defined through the valve stem 184 of the container 104 and also through the actuating button 112. The lower sidewall 206 of the lower portion 202 is generally cylindrical in the present embodiment; however, the lower sidewall 206 may also be tapered. Further, the lower sidewall 206 of the lower portion 202 defines a lower edge 208 of the body 110. As illustrated in FIGS. 11-13, the lower edge 208 of the lower portion 202 is generally circular and defines a lower opening 210 of the body 110. The lower portion 202 may optionally include a lip.

Referring to FIGS. 5-7, the lower sidewall 206 terminates at an angled step 218 at a top of the lower portion 202 of the body 110. The angled step 218 is generally flat and angled upward from a front portion 220 of the body 110 to a rear portion 222 of the body 110. As illustrated in FIGS. 5 and 6, the upper portion 204 of the body 110 extends upwardly from the angled step 218. In particular, the upper portion 204 of the body 110 comprises an outer wall 240 that tapers toward the longitudinal axis A (see FIG. 7) and an inner wall 242 that is generally parallel to the longitudinal axis A (see FIG. 8). The outer wall 240 and the inner wall 242 are connected at a top wall 246 that defines a top edge 248 of the body 110. As illustrated in FIG. 10, the upper portion 204 of the body 110 defines an upper opening 250 of the body 110 that is in communication with the lower opening 210 of the body 110.

Referring again to FIGS. 5-7, the upper portion 204 of the body 110 comprise a window 256 that extends therethrough. In particular, the window 256 extends through the outer wall 240 and the inner wall 242 of the upper portion 204 and defines window sidewalls 258. The window 256 provides an opening in which the first and the second nozzle 120, 122 extend through. It is contemplated that the window 256 can comprise any type of shape or configuration such that the nozzles 120, 122 can extend through the upper portion 204 of the body 110. As illustrated in FIGS. 7 and 9, the body 110 also includes a horn 264 extending outwardly from the upper portion 204, away from the longitudinal axis A. The horn 264 comprise a generally hourglass shape and surrounds the first and the second nozzle 120, 122. The horn 264 further surrounds the window 256 in the upper portion 204 of the body 110. In preferred embodiments, the horn 264 is configured to catch any fluid that may drip from the nozzles 120, 122 during operation of the overcap assembly 102. As illustrated in FIG. 7, the horn 264 is connected with the angled step 218 at a lower portion. In alternative embodiments, the horn 264 may include any shape or size. For example, the horn 264 may comprise a circular, square, or triangular shape instead of having an hourglass configuration.

Referring still to FIGS. 5-7, the top wall 246 of the body 110 is recessed above the window 256. In particular, the top wall 246 is flush with a top portion 266 of the horn 264. As illustrated in FIGS. 5 and 6, the top portion 266 of the horn 264 comprises a spray indicator 268 indicating to the user the direction of the aerosol spray once the actuating button 112 is depressed. The spray indicator 268 may extend onto a portion of the top wall 246. In alternative embodiments, the top portion 266 of the horn 264 may not include the spray indicator 268. Further, it is contemplated that the spray indicator 268 may be any shape, size, or indicator to instruct the user during operation of the overcap assembly 102.

Referring to FIGS. 5 and 6, the actuating button 112 is positioned in the upper opening 250 of the body 110. In particular, the actuating 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 actuating button 112 is depressably connected to the body 110 such that it can move from a first position or unactuated state (see FIG. 14) to a second position or actuated state (see FIG. 26). In preferred embodiments, the actuating button 112 is integrally connected or attached with the body 110. Put differently, in some embodiments, the actuating button 112 is monolithic or monolithically formed with the body 110. However, in alternative embodiments, the actuating button 112 may be separate or independent from the body 110. In preferred embodiments, the body 110 and the actuating button 112 are molded together during an injection molding operation.

Referring still to FIGS. 5 and 6, the actuating button 112 comprises an actuator body 302 having a generally elongated oval shape. The shape of the actuator body 302 is generally similar to the shape of the upper opening 250 of the body 110 (see FIG. 10). The actuator body 302 comprises an upper wall 304 and a sidewall 306 extending around the upper wall 304. The sidewall 306 tapers away from the longitudinal axis A on both sides of the actuating button 112 (see FIG. 10), and the sidewall 306 is generally parallel to the longitudinal axis A on the rear side of the actuating button 112 (see FIG. 14). As illustrated in FIGS. 7 and 8, the upper wall 304 of the actuating button 112 is generally flat and orthogonal to the longitudinal axis A.

Referring still to FIGS. 5 and 6, the upper wall 304 is connected to a rounded wall 310 that connects the upper wall 304 with the sidewall 306 near the rear portion 222 of the body 110. A landing area 314 is positioned on the upper wall 304 and the rounded wall 310. More particularly, the landing area 314 extends into the actuator body 110 of the actuating button 112 and comprises a rounded or bowl like shape. In preferred embodiments, the landing area 314 comprises a plurality of gripping features 316 that extend outwardly from the landing area 314. The landing area 314 is provided as a visual cue for the user on where they should place their finger during operation of the overcap assembly 102. Additionally, the landing area 314 is intended to position the user's finger on a centerline of the actuating button 112, of which the cross-sectional view of FIG. 14 defines the centerline of the actuating button 112 of the overcap assembly 102. Thus, allowing easier (consumer-friendly) actuation of the actuating button 112. The plurality of gripping features 316 give the landing area 314 extra grip such that the user's finger does not slide while actuating the actuating button 112. In some embodiments, the actuating button 112 may not comprise the landing area 314. Instead, the upper wall 304 of the actuating button 112 may be substantially flat and uninterrupted.

Referring to FIG. 7, the first and the second nozzle 120, 122 extend laterally outwardly from the actuating button 112, orthogonal to the longitudinal axis A. In preferred embodiments, the first and the second nozzle 120, 122 are integrally connected with the actuating button 112. As will be discussed in further details herein, the actuating button 112 defines a fluid passageway 330 extending therethrough such that fluid from the container 104 may flow through the actuating button 112 and out the first nozzle 120 and the second nozzle 122 via the first exit aperture 130 and the second exit aperture 132, respectively (see FIG. 4). Therefore, the first and the second nozzle 120, 122 define portions of the fluid passageway 330 extending through the actuating button 112. As illustrated in FIGS. 7 and 14, the actuating button 112 comprises a bridge 336 that extends outwardly from the longitudinal axis A and connects the actuating button 112 with the body 110 at a pivot point 338. As will become more apparent upon further discussion herein, the actuating button 112 translates and/or pivots relative to the body 110 about the pivot point 338 from the unactuated state (see FIG. 14) to the actuated state (see FIG. 26), i.e., the bridge 336 and the pivot point 338 create a living hinge. As further illustrated in FIGS. 7 and 14, the bridge 336 comprises a generally concave geometry (see FIG. 7). The concave geometry of the bridge 336 helps to limit side-to-side motion during actuation of the actuating button 112 and allows the actuating button 112 to depress easier from the unactuated state (see FIG. 14) to the actuated state (see FIG. 26). In alternative embodiments, the bridge 336 may be more rounded than illustrated or may be substantially flat, i.e., not concave.

Referring to FIGS. 7 and 14, the actuating button 112 comprises gussets 342 extending between the first and the second nozzle 120, 122 and between the second nozzle 122 and the bridge 336. The gussets 342 extend from the actuator body 302 and along the first and the second nozzle 120, 122. In preferred embodiments, the gussets 342 add additional support and stability to the actuating button 112 and the first and the second nozzle 120, 122. In particular, the gussets 342 assist in prohibiting the first and the second nozzle 120, 122 from flexing under a torque force, i.e., actuation of the actuating button 112. Specifically, the gussets 342 keep the first and the second nozzles 120, 122 aligned and parallel with each other during use of the overcap assembly 102. Therefore, the gussets 342 limit the nozzles from flexing while a user pushes on the actuating button 112. In some embodiments, the actuating button 112 may not include the gussets 342. In other embodiments, the gussets 342 may be larger or smaller than illustrated (see FIGS. 27 and 32).

Turing to FIGS. 11-13, the lower opening 210 of the body 110 is shown positioned adjacent the lower edge 208 for receiving portions of the container 104 (see FIG. 4). As best seen in FIGS. 11-14, the body 110 includes a plurality of inwardly protruding guiding ribs 350 disposed along an inner surface 352 of the body 110. The guiding ribs 350 are radially spaced from one another and extend from the lower edge 208 in an inward and upward manner 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. As illustrated in FIGS. 11 and 12, some of the guiding ribs 350a extend inwardly along the angled step 218 and upwardly into the upper portion of the body 110. However, as illustrated in FIG. 13, a few of the guiding ribs 350b only extend on the lower sidewall 206 of the lower portion 202 of the body 110. In this case, the guiding ribs 350b comprise a generally rectangular shape and stop short of the recessed lip 280.

Referring to FIG. 12, two of the guiding ribs 350c extend along the inner surface 352 of the body 110 past the window 256. In particular, the two guiding ribs 350c form the window sidewalls 258 in the upper portion 204 of the body 110. As illustrated in FIGS. 12-14, a lower surface 354 of each of the guiding ribs 350 is depicted, wherein such lower surfaces 354 are fashioned to engage with the rim 168 of the container 104 when the overcap assembly 102 is coupled thereto (see FIG. 4). It is contemplated that the guiding ribs 350 may comprises any type of shape and can extend to any height along the inner surface 352 of the body 110. In some embodiments, the body 110 may comprise more or fewer guiding ribs 350 than shown (see FIGS. 30 and 40). As illustrated in FIGS. 11-13, the body 110 and the actuating button 112 comprise a plurality of support ribs 360. The support ribs 360 offer additional support and structural integrity to the overcap assembly 102. It is contemplated that the overcap assembly 102 may include more or fewer support ribs 360 depending on the type of material used, the intended use of the overcap assembly 102, and the operating performance needed by the user. As further illustrated in FIGS. 11-13, an inlet 370 of a vertical conduit 380 of the actuating button 112 extends to join the valve stem 184, resulting in a fluid connection between the actuating button 112 and the container 104 (see FIG. 4). During operation, the vertical conduit 380 is configured to receive a fluid when the actuating button 112 is depressed (see FIG. 26).

Referring to FIGS. 12-14, a plurality of equidistantly spaced securement protrusions 386 are disposed circumferentially about an interior surface 388 of the lower sidewall 206 and are adapted to secure the overcap assembly 102 to the container 104 and/or to allow for variances of different container sizes for use with the overcap assembly 102 (see FIG. 4). In preferred embodiments, the protrusions 386 limit rotation of the body 110 with respect to the container 104 because the protrusions 386 have a light interface with the groove 164 adjacent the rim 168 of the container 104 (see FIG. 4). The protrusions 386 may also relieve pressure on the lower sidewall 206 of the lower portion 202 of the body 110 in the event that a container having a larger diameter, i.e. a diameter that is substantially similar to that of the body 110, is inserted into the body 110 of the overcap assembly 102.

As best seen in FIGS. 3 and 4, upon placement of the overcap assembly 102 onto the container 104, the securement protrusions 386 are fittingly retained within the groove 164 in a snap-fit type manner. Any number and size of the protrusions 386 may be included that circumscribe the interior surface 388 of the lower sidewall 206 to assist in attaching the overcap assembly 102 to the container 104. Alternatively, other methods may be utilized to secure the overcap assembly 102 to the container 104 as are known in the art. Additional stabilizing ribs (not shown) and/or additional securement protrusions 386 may also provide additional structural integrity and/or alignment assistance to the overcap assembly 102 for allowing for secure retention of the overcap assembly 102. Such alignment assistance helps to ensure that the actuating button 112 is positioned correctly onto the valve stem 184.

Referring to FIGS. 14 and 15, the vertical conduit 380 of the actuating button 112 comprises a length L₁ (see FIG. 15) and is shown extending upward toward the upper wall 304 of the actuating button 112 along the longitudinal axis A. As discussed above, the vertical conduit 380 is configured to receive a fluid when the actuating button is depressed. As illustrated in FIG. 15, the vertical conduit 380 is intersected at two separate positions by a first horizontal conduit 402 and a second horizontal conduit 404 extending laterally from and/or orthogonal to the vertical conduit 380 and the longitudinal axis A. In particular, 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 positioned above, spaced apart from, and parallel to the second horizontal conduit 404. As illustrated in FIGS. 14 and 15, the first horizontal conduit 402 defines a portion of the first nozzle 120 and the second horizontal conduit 404 defines a portion of the second nozzle 122. The first and the second horizontal conduit 402, 404 extend from the vertical conduit 380 toward the first exit aperture 130 and the second exit aperture 132, respectively. As such, the first exit aperture 130 defines a portion of the first horizontal conduit 402 and the second exit aperture 132 defines a portion of the second horizontal conduit 404. Additionally, the vertical conduit 380, the first horizontal conduit 402, and the second horizontal conduit 404 generally define the fluid passageway 330 of the actuating button 112.

Referring again to FIG. 15, the first horizontal conduit 402 defines a longitudinal axis C₁ that is orthogonal to the longitudinal axis A, and the first horizontal conduit 402 defines a length L₂. The second horizontal conduit 404 also defines a longitudinal axis C₂ that is orthogonal to the longitudinal axis A, and the second horizontal conduit 404 also defines a length L₃. As illustrated in FIG. 15, the longitudinal axis C₁ is parallel to the 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 alternative embodiments, first horizontal conduit 402 may comprises a larger or smaller length L₂ than the second horizontal conduit 404. As further illustrated in FIG. 15, 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 alternative embodiments, the length L₁ of the vertical conduit 380 may be larger than the length L₂ of the first horizontal conduit 402 and/or the length L₃ of the second horizontal conduit 404. In preferred embodiments, the length L₁ of the vertical conduit 380 can 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 can be equal to the length L₁ and up to 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 can be equal to the length L₁ and up to 2.0 times the length of L₁, i.e., between about 0.30 inches (7.6 mm) and about 3.0 inches (76.2 mm). It is contemplated that the lengths L₁, L₂, and L₃ can comprise any length such that the overcap assembly 102 can affect the aforementioned spray output.

Referring still to FIG. 15, the first horizontal conduit 402 extends through the actuating button 112 and is surrounded by a first inner cylindrical wall 408. As illustrated in FIG. 15, the first inner cylindrical wall 408 extends substantially parallel to the longitudinal axis C₁ from the actuator body 302 of the actuating button 112 to a first inner distal end 410 at the first exit aperture 130. The first inner distal end 410 defines the outermost section (away from the longitudinal axis A) of the first inner cylindrical wall 408. In particular, the first inner distal end 410 defines the first exit aperture 130. As noted herein, the first inner cylindrical wall 408 also defines a portion of the first horizontal conduit 402. As further illustrated in FIG. 15, a first outer cylindrical wall 416 is spaced apart from and surrounds the first inner cylindrical wall 408. The first outer cylindrical wall 416 also extends substantially parallel to the longitudinal axis C₁ from the actuator body 302 of the actuating button 112 to a first outer distal end 418, adjacent to the first exit aperture 130. The first outer distal end 418 defines the outermost section (away from the longitudinal axis A) of the first outer cylindrical wall 416. A first interior space 420 is defined between the first outer cylindrical wall 416 and the first inner cylindrical wall 408. The first interior space 420 comprises a generally annular shape and extends entirely around the first inner cylindrical wall 408, inside the first outer cylindrical wall 416. As a result, the first interior space 420 can be configured to catch any liquid that may drip or spill out of the first exit aperture 130. In some embodiments, the first interior space 420 may not be annular and may not extend entirely around the first inner cylindrical wall 408. Therefore, it is contemplated that the first interior space 420 may comprise any shape or configuration around or partially around the first inner cylindrical wall 408, so long as a portion of the first interior space 420 is provided to catch any liquid that may drip or spill out of the first exit aperture 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 exit aperture 130 define the first nozzle 120.

Referring again to FIG. 15, the second horizontal conduit 404, positioned below the first horizontal conduit 402, extends through the actuating button 112 and is surrounded by a second inner cylindrical wall 430. As illustrated in FIG. 15, the second inner cylindrical wall 430 extends substantially parallel to the longitudinal axis C₂ from the actuator body 302 of the actuating button 112 to a second inner distal end 432 at the second exit aperture 132. The second inner distal end 432 defines the outermost section (away from the longitudinal axis A) of the second inner cylindrical wall 430. In particular, the second inner distal end 432 defines the second exit aperture 132. As noted herein, the second inner cylindrical wall 430 also defines a portion of the second horizontal conduit 404. As further illustrated in FIG. 15, a 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 actuator body 302 of the actuating button 112 to a second outer distal end 440, adjacent to the second exit aperture 132. The second outer distal end 440 defines the outermost section (away from the longitudinal axis A) of the second outer cylindrical wall 438. A second interior space 446 is defined between the second outer cylindrical wall 438 and the second inner cylindrical wall 430. The second interior space 446 comprises a generally annular shape and extends entirely around the second inner cylindrical wall 430, inside the second outer cylindrical wall 438. Similar to the first interior space 420, the second interior space 446 can be configured to catch any liquid that may drip or spill out of the second exit aperture 132. In some embodiments, the second interior space 446 may not be annular and may not extend entirely around the second inner cylindrical wall 430. Therefore, it is contemplated that the second interior space 446 may comprise any shape or configuration around or partially around the second inner cylindrical wall 430, so long as a portion of the second interior space 446 is provided to catch any liquid that may drip or spill out of the second exit aperture 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 exit aperture 132 define the second nozzle 122.

Referring to FIGS. 7 and 15, a plurality of ribs 450 extend in-between the first and the second outer cylindrical wall 416, 438 and the first and the second inner cylindrical wall 408, 430, respectively. In particular, the ribs 450 offer additional support to the first and the second nozzle 120, 122. As illustrated in FIG. 7, the ribs 450 are provided in the first interior space 420 and the second interior space 446. Specifically, each nozzle 120, 122 includes four ribs 450 on each side of the first and the second inner cylindrical wall 408, 430, i.e., top, bottom, right, and left side. As illustrated in FIG. 15, the ribs 450 taper toward the longitudinal axis C₁ and C₂ as they extend from the actuator body 302 toward the first and the second exit aperture 130, 132. In alternative embodiments, each of the nozzles 120, 122 can comprises more or fewer ribs 450.

Referring still to FIG. 15, the first and the second inner cylindrical wall 408, 430 and the first and the second outer cylindrical wall 416, 438 facilitate ribbing for the first and the second nozzle 120, 122, respectively. In particular, the first and the second inner cylindrical wall 408, 430 and the first and the second outer cylindrical wall 416, 438 allow the first and the second nozzle 120, 122 to be double walled. This double walled configuration gives the first and the second nozzles 120, 122 additional support and, therefore, limits deformation in the first and the second nozzle 120, 122. Additionally, the double walled configuration limits the first and the second nozzle 120, 122 from warping, which limits the spray paths of the first and the second nozzle 120, 122 from colliding. Further, besides offering structural support for the first and the second nozzle 120, 122, the double walled configuration also provides a unique visual cue and a recognizable appearance to the user. Specifically, the double walled configuration of the first and the second nozzle 120, 122 shifts the user's attention to the geometry used for the first and second exit apertures 130, 132 in the first and second nozzles 120, 122.

Referring to FIGS. 15-17, the first and second exit apertures 130, 132 are shown having a spherical opening angled with respect to the longitudinal axis C₁ and C₂, respectively. In particular, the first exit aperture 130 is configured to direct the fluid from the container 104 in an upward direction with respect to the longitudinal axis C₁, and the second exit aperture 132 is configured to direct the fluid from the container 104 in a downward direction with respect to the longitudinal axis C₂ (see FIG. 15). Put differently, the geometries of the first exit aperture 130 and the second exit aperture 132 are positioned 180° opposite from each other in a vertical orientation.

Referring to FIG. 15, the first exit aperture 130 and the second exit aperture 132 are not perpendicular and square to the longitudinal axis 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 an angle square to the longitudinal axis C₁ and C₂, i.e., non-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 FIGS. 16-19). Since the first and the second inner distal ends 410, 432 of the first and the second nozzles 120, 122 are spherically cut at an angle with respect to the longitudinal axis C₁ and C₂, the fluid from the container 104 may be directed in diverging directions from one another. The angled spherical cuts defining the first and the second exit aperture 130, 132 allow the fluid to travel farther from the overcap assembly 102 and produce a larger spray pattern or profile on a target. As such, the first and the second nozzle 120, 122 allow the user to not be as accurate while aiming the overcap assembly 102, i.e., the overcap assembly 102 creates a larger and farther moving fluid footprint over the target area. Further, the spherical geometric pattern on the first and the second exit aperture 130, 132 allow the fluid to flow better while exiting the first and the second exit aperture 130, 132. Specifically, the spherical geometry pattern on the first and the second exit aperture 130, 132 limits impingement of the fluid flow and provides better atomization of the fluid.

Referring to FIG. 18, the first inner distal end 410 of the first inner cylindrical wall 408, defining the first exit aperture 130, is shown having a spherical opening that is angled upward with respect to the longitudinal axis C₁. Specifically, the first inner cylindrical wall 408 extends farther below the longitudinal axis C₁ than above it. Therefore, fluid moving through the first nozzle 120 may be directed upwards at an angle with respect to the longitudinal axis C₁. Since the first inner distal end 410 of the first inner cylindrical wall 408 is configured to direct fluid upward, the first outer distal end 418 of the first outer cylindrical wall 416 is also cut at a similar angle with respect to the longitudinal axis C₁ as the first inner distal end 410. In particular, the first outer cylindrical wall 416 compliments the first inner cylindrical wall 408 such that there is no (or substantially no) impingement of the flow during actuation of the overcap assembly 102. As such, a top portion 470 of the first outer distal end 418 is vertically positioned or aligned above a top portion 472 of the first inner distal end 410 (see FIG. 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 define the points or portions of the first inner distal end 410 and the first outer distal end 418, respectively, that extend the least along the horizontal direction (away from the longitudinal axis A), as illustrated in FIG. 15. Therefore, flow exiting the first exit aperture 130 will not be caught 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 extend as far as shown in FIG. 15. Therefore, it is contemplated that the first inner cylindrical wall 408 and the first outer cylindrical wall 416 may extend along the horizontal direction to any length from the longitudinal axis A (see FIG. 15). For example, in some embodiments, the first inner cylindrical wall 408 may extend farther along the horizontal direction (away from the longitudinal axis A) than the first outer cylindrical wall 416. Further, in alternative embodiments, the first outer distal end 418 of the first outer cylindrical wall 416 may comprise multiple sections or portions that have varying length from the longitudinal axis A. For example, a top and bottom portion (relative to the longitudinal axis C₁) of the first outer distal end 418 may extend to one position along the horizontal direction from the longitudinal axis A while the sides of the first outer distal end 418 may extend to a different position along the horizontal direction from the longitudinal axis A.

Referring to FIG. 19, the second inner distal end 432 of the second inner cylindrical wall 430, defining the second exit aperture 132, is shown having a spherical opening that is angled downward with respect to the longitudinal axis C₂. Specifically, the second inner cylindrical wall 430 extends farther above the longitudinal axis C₂ than below it. Therefore, fluid moving through the second nozzle 122 may be directed downwards at an angle with respect to the longitudinal axis C₂. Since the second inner distal end 432 of the second inner cylindrical wall 430 is configured to direct fluid downward, the second outer distal end 440 of the second outer cylindrical wall 438 is also cut at a similar angle with respect to the longitudinal axis C₂ as the second inner distal end 432. In particular, the second outer cylindrical wall 438 compliments the second inner cylindrical wall 430 such that there is no (or substantially no) impingement of the flow during actuation of the overcap assembly 102. As such, a bottom portion 480 of the second outer distal end 440 is vertically positioned or aligned below a bottom portion 482 of the second inner distal end 432 (see FIG. 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 define the points or portions of the second inner distal end 432 and the second outer distal end 440, respectively, that extend the least along the horizontal direction (away from the longitudinal axis A), as illustrated in FIG. 15. Therefore, flow exiting the second exit aperture 132 will not be caught 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 extend as far as shown in FIG. 15. Therefore, it is contemplated that the second inner cylindrical wall 430 and the second outer cylindrical wall 438 may extend along the horizontal direction to any length from the longitudinal axis A (see FIG. 15). For example, in some embodiments, the second inner cylindrical wall 430 may extend farther along the horizontal direction (away from the longitudinal axis A) than the second outer cylindrical wall 438. Further, in alternative embodiments, the second outer distal end 440 of the second outer cylindrical wall 438 may comprise multiple sections or portions that have varying length from the longitudinal axis A. For example, a top and bottom portion (relative to the longitudinal axis C₂) of the second outer distal end 440 may extend to one position along the horizontal direction from the longitudinal axis A while the sides of the second outer distal end 440 may extend to a different position along the horizontal direction from the longitudinal axis A.

Referring to FIGS. 15-19, the first and the second exit aperture 130, 132 are shown having a spherical cut at an angle relative to the longitudinal axis C₁ and C₂. As noted herein, a spherical cut refers to any type of cut/cut-out 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 a curved or arched surface creating an arc. However, in some embodiments, the first and the second exit aperture 130, 132 may comprise 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 comprise any type of spherical, spheroid, curved, or angled cut such that the fluid from the container 104 is directed in different or diverging 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 comprise a straight-line angled cut instead of a spherical cut. Further, in other embodiments, the first nozzle 120 may comprise one type of cut, e.g., spherical cut, and the second nozzle 122 may comprises a different type of cut, e.g., straight-line angled cut. Furthermore, in some embodiments, the first inner distal end 410 of the first inner cylindrical wall 408, defining the first exit aperture 130, and the second inner distal end 432 of the second inner cylindrical wall 430, defining the second exit aperture 132, may comprise a radial spray pattern instead of an angled 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 comprise one or more surfaces or portions with a combination of curves and straight-line cuts. Therefore, it is contemplated that the first nozzle 120 and the second nozzle 122 can comprise any type of geometric angled or radial cut. Furthermore, it is also contemplated that the first nozzle 120 and the second nozzle 122 may have a straight cut, orthogonal to the longitudinal axis C₁ and C₂. As discussed above, in some embodiments, the overcap assembly 102 may include a third nozzle extending between and aligned with (vertically between, i.e., along the longitudinal axis A) the first nozzle 120 and the second nozzle 122. 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 an exit aperture of the third nozzle. For example, the exit aperture of the third nozzle may include a straight cut, orthogonal to the longitudinal axis of the third nozzle, i.e., substantially parallel with the longitudinal axis A and/or substantially orthogonal to the longitudinal axis C₁ and C₂, instead of an angled, spherical cut like the first and second exit apertures 130, 132. Therefore, in use, the first nozzle 120 and the second nozzle 122 would spray the fluid moving through the overcap assembly 102 in diverging directions while the third nozzle would spray the fluid moving through the overcap assembly 102 in a substantially straight direction. It is contemplated that the third nozzle may direct the fluid in a similar or different direction than 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 comprise a rounded lip.

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 may be cut at any angle relative to the longitudinal axis C₁ and C₂. Therefore, it is contemplated that the first exit aperture 130 and the second exit aperture 132 can direct fluid in any direction. It is further contemplated that the first exit aperture 130 and the second exit aperture 132 can direct fluid in the same direction, converging directions, diverging directions, or combinations thereof.

Referring to FIG. 20-22, computational fluid dynamics models of the fluid passageway 330 are shown having different angled first and second exit apertures 130, 132. In particular, each figure shows the direction of the fluid exiting the first and the second exit aperture 130, 132 depending on the angle of the cut taken on 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, an angle Θ represents the angle of the cut relative to the longitudinal axis C₁ and C₂. In particular, the angle Θ is measured from the longitudinal axis C₁ and C₂ to the topmost edge (relative to the longitudinal axis C₁) of the first inner distal end 410 and to a bottom most edge (relative to the longitudinal axis C₂) of the second inner distal end 132 when viewed from the sectional view of FIGS. 21 and 22. Further, an angle Φ represents the angle between the fluid exiting the first nozzle 120 and the fluid exiting the second nozzle 122. As would be apparent to those of ordinary skill of the art, the computational fluid dynamics models shown in FIGS. 20-22 illustrate the angle of the flow of the fluid immediately outside the first nozzle 120 and the second nozzle 122, prior to the flow expanding in the atmosphere.

Referring to FIG. 20, the angle Θ is about 90°, i.e., the first and the second exit aperture 130, 132 are perpendicular and square to the longitudinal axis C₁ and C₂. Therefore, the angle Φ between the fluid leaving the first and the second nozzle 120, 122 is 0° since the first and the second exit aperture 130, 132 are not angled. FIG. 20 illustrates the flow of fluid in typical double nozzle configurations.

Referring to FIG. 21, the angle Θ is about 130°, 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 spherically cut at an angle of about 130°. As such, the angle Φ between the fluid leaving the first and the second nozzle 120, 122 is about 11°. As noted herein, the angle Θ of the first and the second exit aperture 130, 132 of the overcap assembly 102 illustrated in FIGS. 1, 3-19, and 26 is about 130° relative to the longitudinal axis C₁ and C₂, respectively. However, in some embodiments, the angle Θ can be between about 90° and about 170°, or between about 100° and about 160°, or between about 110° and about 150°, or about 130°, or at least 90°, or at least 100°, or at least 110°, or at least 130°, or at least 150°. In preferred embodiments, the angle Θ is between about 90° and about 150°.

Referring to FIG. 22, the angle Θ is about 140°, 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 spherically cut at an angle of about 140°. Thus, the angle between the fluid leaving the first and the second nozzle 120, 122 is about 13°. Therefore, depending on the angle Θ used, the angle Φ of the fluid leaving the first and the second nozzle 120, 122 can be altered accordingly. In some embodiments, the angle Φ can be between about 1° and about 80°, or between about 3° and about 40°, or between about 5° and 20°, or between about 9° and 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 preferred embodiments, the angle Φ is between about 9° and 15°.

As further noted herein, the angle of the second exit aperture 132 will be opposite the angle Θ of the first exit aperture 130. For example, the angle Θ of the first exit aperture 130 in FIG. 21 is about 130° above the longitudinal axis C₁, whereas the angle Θ of the second exit aperture 132 in FIG. 21 is about 130° below the longitudinal axis C₂. As discussed above, it is contemplated 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 axis C₁ and C₂ to form the first and the second exit aperture 130, 132 such that the fluid flowing from the first and the second exit aperture 130, 132 are directed in different or diverging directions.

Referring to FIGS. 23-25, pressure profiles of the fluid at the first and the second exit aperture 130, 132 during actuation of the overcap assembly 102 are shown. In particular, FIG. 23 illustrates the pressure profile when the angle Θ of the first and the second exit apertures 130, 132 is about 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 cut orthogonal to the longitudinal axis C₁ and C₂ (see FIG. 20). As illustrated in FIG. 23, the pressure profile is symmetrical (or substantially symmetrical) about the center of the first and the second exit aperture 130, 132. As noted herein, FIGS. 23-25 illustrate the pressure profiles of the fluid at the first and the second exit aperture 130, 132 just before the fluid reaches the atmosphere.

Referring to FIG. 24, the angle Θ of the first and the second exit aperture 130, 132 is about 130° (see FIG. 21). As such, the pressure of the fluid is higher near a bottom portion 486 of the first horizontal conduit 402 than a top portion 488 of the first horizontal conduit 402. Additionally, the pressure of the fluid is higher near a top portion 490 of the second horizontal conduit 404 than a bottom portion 492 of the second horizontal conduit 404. Thus, the pressure profile of the fluid exiting the angled first and second exit apertures 130, 132 (see FIG. 24) is different than the pressure profile of the fluid exiting the non-angled first and second exit apertures 130, 132 (see FIG. 23). In particular, the pressure profile or gradient of the fluid follows the shape of the first and the second exit apertures 130, 132 when Θ equals 90° (see FIG. 23). In other words, the fluid profile has a circular uniform distribution of pressure around the center of the first and the second exit aperture 130, 132 when Θ equals 90° (see FIG. 23). Alternatively, the pressure profile or gradient of the fluid is asymmetrical to the shape of the first and the second exit aperture 130, 132 when Θ is greater than 90° (see FIGS. 24 and 25). Therefore, as the angle Θ increases from 90°, the pressure profile of the fluid will move away from a symmetrical gradient.

Referring to FIG. 25, the angle Θ of the first and the second exit aperture 130, 132 is about 140° (see FIG. 22). As a result, similar to FIG. 24, the pressure of the fluid in FIG. 25 is highest near the bottom portion 486 of the first horizontal conduit 402 or first nozzle 120 and the top portion 488 of the second horizontal conduit 404 or second nozzle 122.

Referring to FIGS. 23-25, the pressure profile of the fluid changes depending on the angle Θ used. In particular, when spherically angled first and second exit aperture 130, 132 are used, the pressure of the fluid increases in the bottom of the first horizontal conduit 402 and the top of the second horizontal conduit 404. This results in the pressure gradient of the fluid changing vertically (see FIGS. 24 and 25) as opposed to radially (see FIG. 23) when the first and second exit aperture 130, 132 are not angled. Further, the spherically angled exit apertures 130, 132 increase the pressure across the first and the second exit aperture 130, 132. Specifically, as illustrated in FIG. 25, the pressure profile at the first and the second exit aperture 130, 132 is substantially larger across a larger area than the pressure profile shown in FIG. 23. The larger pressure profiles across the first and the second exit aperture 130, 132 help to better distribute the fluid into the atmosphere and create a wider and/or larger spray area. In preferred embodiments, the first and the second angled exit aperture 130, 132 (see FIGS. 24 and 25) create about a 10%-40% wider and/or larger spray area than non-angled exit apertures 130, 132 (see FIG. 23). In some embodiments, the first and the second angled exit apertures 130, 132 create about a 30% wider and/or larger spray area.

Referring back to FIG. 23, the pressure of the fluid is circumferentially consistent at each radial level of the non-angled first and the second exit aperture 130, 132, i.e., the pressure change between two points on a circumference of a circle inside and centered in the first and the second exit aperture 130, 132 will be generally zero. Put differently, the net pressure gradient around a circumference of a circle defined in the first and the second exit aperture 130, 132 (and centered therein about the longitudinal axes C₁, C₂) will be generally zero in the non-angled case (see FIG. 23). In contrast, the net pressure gradient around a circumference of a circle in the angled first and the second exit aperture 130, 132 (see FIGS. 24 and 25) is not equal to zero, i.e., the pressure change between two points on a circumference of a circle inside and centered (along the longitudinal axes C₁, C₂) in the first and the second exit aperture 130, 132 will not be zero. Therefore, as illustrated in FIGS. 24 and 25, the pressure profile of the first and the second exit aperture 130, 132 will be generally irregular when the angle Θ is greater than 90°. In particular, as discussed 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 around a circumference of a circle centered (along the longitudinal axes C₁, C₂) in the angled first and the second exit aperture 130, 132 can be +/−0-300,000 Pa.

Referring to FIGS. 15-19 and 23-25, the first and the second exit aperture 130, 132 and the first and the second horizontal conduit 402, 404 comprise a generally circular cross section (see FIGS. 23-25). However, in alternative embodiments, the first and the second exit aperture 130, 132 and the first and the second horizontal conduit 402, 404 may comprise any type of cross sectional profile. For example, the first and the second exit aperture 130, 132 and the first and the second horizontal conduit 402, 404 may comprise an hourglass shaped profile, a square profile, a triangular profile, or any type of polygonal shaped profile. In some embodiments, the first and the second exit aperture 130, 132 and the first and the second horizontal conduit 402, 404 may be shaped as an ellipse. Depending on the shape of the first and the second exit aperture 130, 132 and the first and the second horizontal conduit 402, 404, the pressure profile of the fluid will generally follow the shape of the first and the second exit aperture 130, 132 and the first and the second horizontal conduit 402, 404 when the angle Θ is equal to 90°. In contrast, the pressure profile of the fluid will differ once the angle Θ is greater than 90°.

Referring back to FIGS. 14 and 15, when a user actuates the actuating button 112 for dispensement, fluid travels through the valve stem 184 (see FIG. 4), into the vertical conduit 380, and into the first and/or the second horizontal conduit 402, 404, where the pressurized fluid exits the overcap assembly 102 into the surrounding atmosphere through the first exit aperture 130 and the second exit aperture 132. Therefore, the fluid may travel out of the actuating button 112 through either the first horizontal conduit 402 or the second horizontal conduit 404. In preferred embodiments, a cross section of the passageway within the vertical conduit 380 is greater than a cross section of the passageway within the first and the second horizontal conduit 402, 404, which may necessarily result in a higher fluid pressure in the first and the second horizontal conduit 402, 404 during dispensement of the fluid. As a result, pressure of the fluid at different points along the fluid passageway 330 can be adjusted based on varying cross-sectional areas of different portions of the fluid passageway 330.

Referring still to FIGS. 14 and 15, the cross section of the passageway within the first horizontal conduit 402 is the same as the cross section of the passageway within the second horizontal conduit 404. However, in alternative embodiments, the cross section of the passageway within the first horizontal conduit 402 may be smaller than the cross section of the passageway within the second horizontal conduit 404 and vise-versa. As such, the discharge rate of the fluid can be balanced between the first horizontal conduit 402 and the second horizontal conduit 404. Further, in some embodiments, the first horizontal conduit 402 and/or the second horizontal conduit 404 may include a choke (see FIGS. 32 and 43). For example, one section of the first horizontal conduit 402 and/or the second horizontal conduit 404 may include a diameter smaller than a different section of the first horizontal conduit 402 and/or the second horizontal conduit 404. The variation and size of the cross section of the passageway for the first and the second horizontal conduits 402, 404 influences the particle droplet size of the fluid. Therefore, the first and the second horizontal conduits 402, 404 may be adjusted to produce an ideal particle droplet size of the fluid. As noted herein, the vertical conduit 380, the first horizontal conduit 402, and the second horizontal conduit 404 define a manifold 502.

Now referring to FIGS. 14 and 26, operation of the overcap assembly 102 will be described in greater detail. The overcap assembly 102 is shown in a non-actuated configuration in FIG. 14 and an actuated configuration in FIG. 26. In use, the product or fluid is sprayed from the dispensing system 100 by exerting a force on the actuating button 112 (see FIG. 4). Referring to FIG. 26, which shows the overcap assembly 102 during actuation, the vertical conduit 380 is forced downward, and presses down on the valve stem 184 (see FIG. 4) to cause the valve assembly to allow product or fluid to enter into the manifold 502. In particular, once the user engages the landing area 314 of the actuating button 112, the actuating button 112 translates and pivots about the pivot point 338. In a preferred embodiment, the valve stem 184 translates between about 0.0 inches (0.0 mm) and about 0.2 inches (5.1 mm) from the non-actuation position to the actuation position (see FIG. 4). Upon removal of force from the actuating button 112, the manifold 502 returns to the non-actuation position, as shown in FIG. 14. The actuating button 112 is moved to the non-actuation position by the force of the valve stem 184 moving upwardly by the valve spring (not shown) to close the valve assembly within the container 104 (see FIG. 4).

It should also be noted that the overcap assembly 102 depicted in FIG. 26 in the actuation state is shown in a fully actuated state. However, depending on the tolerance or specific characteristics of the container and/or valve stem and accompanying valve assembly, it is possible that spraying may be effected either fully or partially by pressing the actuating button 112 downward somewhere between the two positions shown in FIG. 14 (non-actuated) and FIG. 26 (fully actuated). However, for purposes of explaining the functionality and interaction of the actuating button 112 with the body 110, the term “actuation state” as it relates to the overcap assembly 102 shown in FIG. 26 refers to what is, in fact, a fully actuated state of the overcap assembly 102.

With reference still to FIGS. 14 and 26, when a user exerts a force on the landing area 314 of the actuating button 112 to translate the actuating button 112 from its non-actuation state, the first and the second exit aperture 130, 132 move from a first position to a second position. Referring to FIG. 14, the actuating button 112 remains in the non-actuation state due to the force of the valve spring (not shown) until a user presses downwardly on the landing area 314 of the actuating button 112 to translate and/or rotate the actuating button 112 from the non-actuation state to the actuation state. Referring now to FIG. 26, the actuating button 112 is shown translated vertically downward and rotated in a clockwise direction about the pivot point 338 to the actuation state. As discussed above, the actuating button 112 remains in the actuation state until a user releases the landing area 314 of the actuating button 112 to allow translation and/or rotation of the actuating button 112 from the actuation state (FIG. 26) back to the non-actuation state (FIG. 14).

With reference to FIGS. 27-32, like reference numbers are used with regard to an alternative embodiment of an overcap assembly 602. As noted herein, the overcap assembly 602 is configured to attach to the container 104 (see FIG. 2) and is substantially similar to the overcap assembly 102 except for a few differences, which will be explained in detail below. As illustrated in FIGS. 27, 29, and 32, the actuating button 112 of the overcap assembly 602 comprises gussets 604 that extend between the first and the second nozzle 120, 122 and between the second nozzle 122 and the bridge 336. As noted herein, the gussets 604 extend farther outward from the actuator body 302 than the gussets 342 (see FIGS. 7 and 14). Therefore, the gussets 604 are able to provide additional stability and support to the first and the second nozzle 120, 122 and the actuating button 112. As discussed above, the gussets 604 keep the first and the second nozzle 120, 122 aligned and parallel while the actuating button 112 is under a torque force, e.g., when the user presses on the actuating button 112 to dispense the fluid. Therefore, the fluid streams exiting the first and the second nozzle 120, 122 are consistent each time the actuating button 112 is depressed.

With reference to FIGS. 27 and 29-32, the bridge 336 comprises a concave geometry (see FIG. 29). In alternative embodiments, the bridge 336 may comprises any type of geometry, e.g., flat or splined geometry. As illustrated in FIGS. 30 and 31, the bridge 336 also comprises a plurality of reinforcing ribs 612 on an underside 614 of the bridge 336. The plurality of reinforcing ribs 612 extend horizontally and generally vertically along the underside 614 of the bridge 336. The concave geometry of the bridge 336 and the plurality of reinforcing ribs 612 help to limit side-to-side movement of the bridge 336 and the actuating button 112 during actuation. Therefore, the concave geometry of the bridge 336 and the plurality of reinforcing ribs 612 incline the actuating button 112 to track closer to a centerline of the actuating button 112, of which the cross sectional view of FIG. 32 defines the centerline of the actuating button 112 of the overcap assembly 602. In some embodiments, the underside 614 of the bridge 336 may comprise more or fewer reinforcing ribs 612 than shown.

With reference to FIG. 28, the body 110 of the overcap assembly 602 comprises 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 overcap assembly 602. In particular, the lip 620 comprises a generally concave shape as it extends between both sides of upper portion 204. A recessed wall 622 extends from the lip 620 and toward the actuating button 112. As illustrated in FIG. 28, outer edges 624 of the recessed wall 622 are positioned behind the lip 620. In preferred embodiments, the outer edges 624 of the recessed wall 622 also extend upward along the inner wall 242 of the upper portion 204 of the body 110 on both sides of the overcap assembly 602. However, in some embodiments, the outer edges 624 may not extend upward along the inner wall 242 of the upper portion 204 of the body 110. As illustrated in FIG. 32, the recessed wall 622 extends generally straight from the lip 620 and toward the actuating button 112, however, in some embodiments, the recessed wall 622 may extend upwards at a slight angle from the lip 620 and toward the actuating button 112. The lip 620 and the recessed wall 622 help give the overcap assembly 602 additional structural support.

With reference to FIGS. 30 and 31, the overcap assembly 602 includes additional guiding ribs 350 than previously shown (see the overcap assembly 102 in FIGS. 11-13). In particular, the overcap assembly 602 includes about twice as many guiding ribs 350 than the overcap assembly 102. As illustrated in FIGS. 30 and 31, the body 110 of the overcap assembly 602 includes curved ribs 630 that extend along the angled step 218 of the body 110 and through the guiding ribs 350a. The curved ribs 630 extend on opposite sides of the body 110 and are generally symmetrical about the center line of the overcap assembly 602. The additional guiding ribs 350 and the curved ribs 630 add additional structural support to the overcap assembly 602. Specifically, the additional guiding ribs 350 and the curved ribs 630 increase the overcap assembly's 602 ability to withstand higher top load forces for package distribution requirements, i.e., the overcap assembly 602 is able to be stored longer without the overcap assembly 602 collapsing. The increased structural support also allows the overcap assembly 602 to have a longer life span. As illustrated in FIG. 30, the overcap assembly 602 includes two curved ribs 630, however, in alternative embodiments, the overcap assembly 602 may include more or fewer curved ribs 630.

With reference to FIG. 32, the first horizontal conduit 402 comprises a choke 640 near the vertical conduit 380. As illustrated in FIG. 32, the choke 640 causes the diameter of the first horizontal conduit 402 to increase from its initial diameter which is connected with the vertical conduit 380. The choke 640 helps balance the discharge rate of the fluid between the first horizontal conduit 402 and the second horizontal conduit 404. In some embodiments, the second horizontal conduit 404 may also include a choke similar to the choke 640 in the first horizontal conduit 402. In other embodiments, the first horizontal conduit 402 may not include the choke 640. Further, in some embodiments, the overcap assembly 602 may include a third nozzle, as discussed above.

As noted herein, the overcap assembly 602 functions the same as the overcap assembly 102. In particular, once the actuating button 112 of the overcap assembly 602 is depressed, fluid from the valve stem 184 of the container 104 (see FIG. 2) moves through the fluid passageway 330 (see FIG. 30) and out one of the first and the second exit aperture 130, 132. The first and the second exit aperture 130, 132 of the overcap assembly 602 comprise a spherical angled cut in order to direct the fluid in diverging directions, similar as described above with respect to the overcap assembly 102. Furthermore, the overcap assembly 602 comprises the same manifold 502 as the overcap assembly 102. Thus, the overcap assembly 602 comprises the same vertical conduit 380, the first horizontal conduit 402, and the second horizontal conduit 404 as the overcap assembly 102.

With reference to FIGS. 33-43, like reference numbers are used with regard to another alternative embodiment of an overcap assembly 702. As noted herein, the overcap assembly 702 is configured to attach to the container 104 (see FIG. 2) and is substantially similar to the overcap assembly 102, 602 except for a few differences, which will be explained in detail below. As illustrated in FIGS. 33, 35, and 36, the upper portion 204 of the body 110 of the overcap assembly 702 comprises a curved outer wall 704. As illustrated in FIG. 35, the curved outer wall 704 generally curves toward the longitudinal axis A from the angled step 218 and ends at the top edge 248 of the body 110. The curved outer wall 704 defines a generally concave shape when viewing the overcap assembly 702 from the right and left sides (see FIG. 35). Further, the curved outer wall 704 is more pronounced near the right and left sides of the body 110 than the front portion 220 of the body 110 (see FIGS. 33 and 35). As illustrated in FIG. 36, the curved outer wall 704 also creates a smoother transition between the curved outer wall 704, the angled step 218, and the lower portion 202 of the body 110.

With reference to FIG. 35, the curved outer wall 704 of the body 110 extends farther down toward the lower portion 202 of the body 110 than the outer wall 240 of the overcap assembly 102, 602. As a result, the angled step 218 in the overcap assembly 702 is smaller, i.e., has a smaller surface area, than the angled step 218 in the overcap assembly 102, 602 (see FIGS. 7 and 29). As noted herein, the curved outer wall 704 of the body 110 of the overcap assembly 702 increases the top load capability of the overcap assembly 702. Specifically, the curved outer wall 704 increases the overcap assembly's 702 ability to withstand higher top load forces for package distribution requirements, i.e., the overcap assembly 702 is able to be stored longer without the overcap assembly 702 collapsing. The curved outer wall 704 also allows the overcap assembly 702 to have a longer life span. As illustrated in FIG. 35, unlike the overcap assembly 102, 602, the horn 264 of the overcap assembly 702 is not connected to the angled step 218. However, in some embodiments, the horn 264 of the overcap assembly 702 may comprise various ribs or supports that connect with the angled step 218.

With reference to FIGS. 40 and 41, the overcap assembly 702 includes a different configuration of the guiding ribs 350 than previously shown (see the overcap assembly 102 in FIGS. 11-13 and the overcap assembly 602 in FIGS. 30 and 31). In particular, the overcap assembly 702 includes more guiding ribs 350a and a different configuration of guiding ribs 350b than the overcap assembly 102, 602. Further, the body 110 of the overcap assembly 702 includes a rounded rib 720 that extends along the angled step 218 of the body 110 and through some of the guiding ribs 350b. The rounded rib 720 is positioned near the front portion 220 of the body 110 and forms a crescent like shape that extends through the two guiding ribs 350c. As illustrated in FIG. 40, the rounded rib 720 starts and ends at one of the guiding ribs 350b. However, in some embodiments, the rounded rib 720 may extend farther or shorter than shown.

With reference still to FIGS. 40 and 41, the overcap assembly 702 also comprises an upper wall rib 722 on both sides of the body 110. The upper wall ribs 722 are elongated round ribs (saber-tooth shaped) that extend from a lower portion of the curved outer wall 704 (adjacent the angled step 218) to the top wall 246 of the body 110. The upper wall ribs 722 are also connected with the inner wall 242 of the body 110. The additional guiding ribs 350, the rounded rib 720, and the upper wall ribs 722 add additional structural support to the overcap assembly 702. Specifically, the additional guiding ribs 350, the rounded rib 720, and the upper wall ribs 722 increase the overcap assembly's 702 ability to withstand higher top load forces for package distribution requirements and/or support the curved outer wall 704 of the body 110. In some embodiments, the body 110 of the overcap assembly 702 may comprise more or fewer rounded ribs 720 and/or upper wall ribs 722 than shown. As illustrated in FIGS. 40, 41, and 43, the overcap assembly 702 also comprises a ledge 726 positioned between the rounded rib 720 and the plurality of reinforcing ribs 612 on the underside 614 of the bridge 336. The ledge 726 extends along a similar path as the rounded rib 720.

With reference to FIG. 43, similar to the overcap assembly 602, the overcap assembly 702 comprises the choke 640 within the first horizontal conduit 402 near the vertical conduit 380. As discussed above, the choke 640 causes the diameter of the first horizontal conduit 402 to increase from its initial diameter, which is connected with the vertical conduit 380. The choke 640 helps balance the discharge rate of the fluid between the first horizontal conduit 402 and the second horizontal conduit 404. In particular, the choke 640 can increase the speed and/or pressure of the fluid that extends through the first horizontal conduit 402. As noted herein, the choke 640 can comprise any diameter gradient in the first horizontal conduit 402 in order to achieve the desired spray characterizes. For example, in some embodiments, the choke 640 may increase the diameter of the first horizontal conduit 402 more or less than shown. Further, in some embodiments, the second horizontal conduit 404 may also include a choke similar to the choke 640 in the first horizontal conduit 402. In other embodiments, the first horizontal conduit 402 may not include the choke 640 (see FIG. 14). Furthermore, in some embodiments, the first horizontal conduit 402 and/or the second horizontal conduit 404 may comprise a choke with a decreasing diameter, i.e., the diameter within the first horizontal conduit 402 and/or the second horizontal conduit 404 decreases from its initial diameter. Further, in some embodiments, the overcap assembly 702 may include a third nozzle, as discussed above.

With reference to FIG. 42, the first and the second exit aperture 130, 132 of the overcap assembly 702 comprises a spherical angled cut that directs the fluid from the container 104 (see FIG. 2) in diverging directions, similar as described above with respect to the overcap assembly 102, 602. Further, as noted herein, the overcap assembly 702 functions the same as the overcap assembly 102, 602. In particular, once the actuating button 112 of the overcap assembly 702 is depressed, fluid from the valve stem 184 of the container 104 (see FIG. 2) moves through the fluid passageway 330 (see FIG. 43) and out one of the first and the second exit aperture 130, 132. Furthermore, the overcap assembly 702 comprises the same manifold 502 as the overcap assembly 102. Thus, the overcap assembly 702 comprises the same vertical conduit 380, the first horizontal conduit 402, and the second horizontal conduit 404 as the overcap assembly 102.

From the foregoing, it will be appreciated that the overcap assembly 102, 602, 702 allows for the fluid from the container 104 to flow through the manifold 502 and out the first and the second nozzle 120, 122 in diverging directions because of the spherical angled geometry at the first and the second exit aperture 130, 132. Since the fluid exits the overcap assembly 102, 602, 702 in diverging directions, the fluid can travel farther into the atmosphere from the overcap assembly 102, 602 and produce a larger spray profile or pattern on a target, thus allowing a larger area to receive the fluid from the container 104.

It is contemplated that the overcap assembly 102, 602, 702 disclosed herein may be mated with a container that has a non-vertical valve assembly or with a valve stem that requires angular motion for actuation. Further, while the teachings of the present overcap assemblies are particularly beneficial to containers having smaller footprints, the present embodiments could be utilized with any size container.

Any of the embodiments described herein may be modified to include any of the structures or methodologies disclosed in connection with different embodiments. Further, the present disclosure is not limited to aerosol containers of the type specifically shown. Still further, the overcaps of any of the embodiments disclosed herein may be modified to work with any type of aerosol or non-aerosol container.
