[0007] This disclosure generally relates to a dispensing system including an actuator assembly placed on a container, and more specifically to a dispensing system that utilizes compressed gas, a modified formulation and pressure within the container, and an improved nozzle insert to achieve a more desirable injection pattern that reduces sedimentation. Background Technology
[0008] Aerosol containers are commonly used to store and dispense products such as air fresheners, deodorants, insecticides, disinfectants, decongestants, perfumes, or any other known products. A hydrocarbon or non-hydrocarbon propellant forces the product out of the container through an aerosol valve. A typical aerosol container includes a body with an opening at its apex. A mounting cup is rolled up to the opening of the container to seal the apex of the body. The geometry of the mounting cup is typically circular and may include an outer wall extending upward from a base adjacent to the rolled-up area of the mounting cup. A base also extends upward from a central portion of the base. A valve assembly includes a valve stem, a valve body, and a valve spring. The valve stem extends through the base, with its distal end extending upward away from the base and its proximal end disposed within the valve body. The valve body is secured inside the mounting cup, and a suction tube may be attached to the valve body. This suction tube extends downward into the interior of the container body. The distal end of the valve stem is axially pressed down along its longitudinal axis to open the valve assembly. 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 opens, the pressure difference between the inside of the container and the atmosphere forces the contents of the container to be discharged through the orifice of the valve stem.
[0009] Aerosol containers typically include an actuator assembly that covers the top of the container. A typical top cap or actuator assembly is releasably attached to the container by an outwardly projecting ridge that defines the inner lower edge of the actuator assembly and interacts with a curled seam defining the top of the container. When the assembly is placed on top of the container, downward pressure is applied to the assembly, causing the ridge to straddle the outer edge of the seam and lock beneath a flange defined by the lower surface of the seam. In some systems, the actuator assembly includes a dispensing orifice to allow product to be discharged through it. In such systems, the actuator typically interacts with a valve stem to release product into the actuator and through the dispensing orifice of the actuator assembly. Furthermore, such actuators typically include an actuation mechanism, such as a button or trigger, integrated with the actuator. In some cases, such as a nozzle assembly for the container included on a larger actuator assembly, it can include a nozzle insert and a corresponding nozzle insert cavity. During manufacturing (or at other times), a specific nozzle insert can be inserted into a nozzle insert cavity to form a combined nozzle assembly capable of providing desired flow characteristics (e.g., injection pattern, flow rate, metering effect, etc.).
[0010] All of the aforementioned characteristics of a dispensing system affect spray characteristics. In a particular content of a fragrance dispensing system, sedimentation is a spray characteristic produced by aerosol spraying, which can be harmful by creating residues along various surfaces within the spray zone. Unwanted residues resulting from increased sedimentation are generally an undesirable effect and can cause unwanted moisture for consumers. Furthermore, many prior art dispensing systems dispense inconsistent sprays throughout the product's lifespan and fail to provide adequate fragrance coverage in enclosed spaces. This disclosure generally relates to dispensing systems, and more specifically to product dispensing systems having actuators with nozzle inserts that address one or more aspects of prior art dispensing systems. Summary of the Invention
[0011] According to some aspects of this disclosure, a dispensing system comprising a composition including one or more of a deodorizing composition, a fragrance composition, or a cleaning composition. Furthermore, the dispensing system includes a container having a cylindrical body and defining a pressure within the body. The composition is placed within the container at a pressure of at least 930 kPa. An actuator assembly is attached to the container, the actuator assembly including a housing, an actuator located within the housing, and a nozzle insert disposed within a fluid channel, the actuator having a fluid channel in fluid communication with the composition. The nozzle insert defines a nozzle orifice having an orifice diameter between about 0.335 mm and about 0.385 mm, and the composition includes a compressed gas and about 5% to about 10% by volume of ethanol.
[0012] In some embodiments, a dispensing system comprising a composition comprising one or more of a deodorizing composition, a fragrance composition, or a cleaning composition. The dispensing system includes a container having a valve stem defining a longitudinal axis and a body defining pressure within the container. The composition is placed within the container at a pressure of at least 930 kPa. An actuator assembly is attached to the container. The actuator assembly includes a housing, an actuator located within the housing and including a fluid channel in fluid communication with the composition, and a nozzle insert disposed within the fluid channel, the nozzle insert defining a jet axis offset from the longitudinal axis by about 60° to about 70°. The composition comprises a compressed gas and about 5% by volume to about 10% by volume of ethanol.
[0013] In some embodiments, a method of dispensing a composition comprising one or more of a deodorizing composition, a fragrance composition, or a cleaning composition includes the step of providing a container having a body and defining a pressure therein, the composition being placed within the container, and the pressure being at least 930 kPa. The method further includes the step of attaching an actuator assembly to the container, the actuator assembly including a housing, an actuator located within the housing and including a fluid channel in fluid communication with the composition, and a nozzle insert disposed within the fluid channel. The method further includes the step of spraying the composition with a settling depth between 25% and 30% from a spray height between four and five feet. Attached Figure Description

[0052] This disclosure provides a dispensing system for use as an air freshener and / or odor eliminator, comprising a compressed gas aerosol with improved spray performance. The dispensing system disclosed herein achieves spray characteristics that provide an enhanced consumer experience by reducing settling from the sprayed aerosol. Settling can be characterized as the humidity of the spray plume in the air and / or the accumulation of residues on surfaces after use of the dispensing system. This disclosure identifies key spray characteristics and formulation parameters that have been found to reduce and / or improve settling from compressed gas dispensing systems. Spray characteristics include particle size, emission rate, spray angle, spray distance, spray cone diameter, settling percentage, settling pattern, and particle velocity. Formulation parameters include the percentage of volatile organic compounds (“VOCs”) in the composition, solvent used, fill pressure, and headspace percentage.
[0053] The spray performance of compressed gas aerosols is influenced by the formulation and the components used to contain it. More specifically, performance is significantly affected by the spray insert or mechanical breakup unit (“MBU”) used to atomize the formulation. The function of the MBU is to disperse the liquid formulation to produce particles for output, for its intended use. The formulation and components are designed to produce the desired spray characteristics. While the methods and systems disclosed herein can be implemented in many different forms, several specific embodiments are discussed herein, and it should be understood that the embodiments described in this disclosure are considered merely as examples of the principles described herein, and this disclosure is not intended to be limited to the embodiments shown. Throughout this disclosure, the terms “about” and “approximately” refer to ±5% of the preceding figures or values for each term.
[0054] Now for reference Figure 1 The diagram illustrates a product dispensing system 60 configured to store and / or dispense aerosol products (not shown). The dispensing system 60 includes a container 62 and an actuator assembly 64, which includes a housing 66, an actuator 68, and a nozzle insert 70 (see [link to diagram]). Figure 2 In use, actuator assembly 64 is configured to release product from container 62 in the event of a specific condition. For example, a user of product dispensing system 60 may manually press or otherwise activate actuator 68 of actuator assembly 64 to release aerosol from container 62. Throughout the disclosure, actuator assembly 64 is shown in various configurations.
[0055] The composition may be an aqueous formulation for use as a pressurized product for emission. Preferably, one or more compressed gases, such as carbon dioxide, helium, hydrogen, neon, oxygen, xenon, nitric oxide, or nitrogen, are used to pressurize the composition, and the composition further includes one or more polar solvents, such as alcohols, ketones, carboxylic acids, or amides. In a preferred embodiment, the polar solvent is an alcohol, more specifically ethanol. Although the product dispensing system 60 is broadly suitable for dispensing any quantity of aqueous formulations, this dispensing system 60, as disclosed herein, is specifically configured to dispense one or more of deodorizing compositions, fragrance compositions, and cleaning compositions. In a preferred embodiment, the composition comprises an organic compound having a hydroxyl group and is pressurized using one or more of the aforementioned compressed gases.
[0056] Reference Figure 2The container 62 includes a generally cylindrical body 74 defining an outer sidewall 76. Additionally, a seam 78 and / or mounting cup 80 provide a location where the actuator assembly 64 can be attached, as known in the art. A conventional valve assembly 84 is shown, comprising a valve stem 86 connected to a valve body (not shown) and a valve spring (not shown) disposed within the container 62. The valve stem 86 extends upward through a base 88 such that a distal end 90 extends upward away from the base 88 and is adapted to interact with a valve seat 92 disposed within the actuator 68. A longitudinal axis 94 extends through the valve stem 86. Prior to use, the actuator 68 is configured to be in fluid communication with the distal end 90 of the valve stem 86. A user can manually or automatically operate the actuator 68 to open the valve assembly, resulting in a pressure difference between the container interior and the atmosphere, forcing the contents out of the container 62 through the valve stem 86 and the actuator assembly 64 and into the atmosphere. It should be noted that the valve stem 86 is shown in a configuration that is not fully seated within the valve seat 92 of the actuator 68, and additional assembly steps are required to allow the valve stem 86 to be fully seated therein. Furthermore, although the valve stem 86 is shown as an integral part of the container 62, the valve stem 86 can be provided in various configurations and is provided only for illustrative purposes.
[0057] Still refer to Figure 2 The container 62 includes a lower base 98 that is curled or otherwise attached to a body 74 at its bottom end 100. The body 74 also defines a top end 102 that defines an opening 104. A mounting cup 80 is curled onto a tapered portion of the container 62 that defines the opening 104. The mounting cup 80 seals the top end 102 of the body 74. The curled portion between the mounting cup 80 and the container 62 defines a seam 78 that provides a location along which an actuator assembly 64 can be attached in a manner known in the art.
[0058] While any amount of pressurized product can be used in container 62, the preferred composition uses compressed gas pressurization and includes alcohols, such as ethanol. More specifically, the composition includes about 4% by volume (%V) to about 15% by volume of ethanol, or about 6% by volume to about 13% by volume of ethanol, or about 8% by volume to about 11% by volume of ethanol, or at least 5% by volume of ethanol, or at least 7% by volume of ethanol, or at least 8% by volume of ethanol, or at least 9% by volume of ethanol, or at least 10% by volume of ethanol, or at least 11% by volume of ethanol. Testing has determined that the aforementioned ethanol content in the composition within container 62 helps to promote evaporation, thereby reducing undesirable sedimentation along various surfaces near the spray. For this purpose, it has been found that increasing the amount of ethanol in the composition can accelerate or increase the evaporation rate and reduce corrosion of container 62.
[0059] Still refer to Figure 2The outer sidewall 76 defines a thickness 108. While the sidewall 76 of container 62 preferably comprises steel, it may comprise a variety of materials known in the art, such as aluminum or plastic. In a preferred embodiment, the thickness 108 of the sidewall 76 of the container is between about 0.005 inches (0.13 mm) and about 0.04 inches (1.02 mm), or between about 0.01 inches (0.25 mm) and about 0.03 inches (0.76 mm), or about 0.02 inches (0.51 mm), or at least 0.005 inches (0.13 mm), or at least 0.01 inches (0.25 mm), or at least 0.015 inches (0.38 mm), or at least 0.02 inches (0.51 mm), or at least 0.025 inches (0.64 mm), or at least 0.03 inches (0.76 mm). The thickness of container 62 may be increased depending on the pressure within the container.
[0060] As discussed below, when the user actuates actuator 68, increasing the pressure within container 62 by dispersing the sprayed particles and delivering them away from the distribution system 60 helps reduce settling. In some embodiments, the container may have a pressure between approximately 120 pounds per square inch (psi) (827 kPa) and approximately 180 psi (1241 kPa), or between approximately 130 psi (896 kPa) and approximately 170 psi (1172 kPa), or between approximately 140 psi (965 kPa) and approximately 160 psi (1103 kPa), or between approximately 150 psi (1034 kPa) and approximately 155 psi (1068 kPa), or between approximately 152 psi (1048 kPa) and approximately 153 psi (1055 kPa). Between, or approximately 150 psi (1034 kPa), or approximately 152 psi (1048 kPa), or approximately 153 psi (1055 kPa), or at least 120 psi (827 kPa), or at least 130 psi (896 kPa), or at least 140 psi (965 kPa), or at least 145 psi (999 kPa), or at least 150 psi (1034 kPa), or at least 155 psi (1068 kPa), or at least 160 psi (1103 kPa), or at least 170 psi (1172 kPa). Furthermore, at 100% capacity, i.e., when fully filled, the top space of container 62 may define between about 10% and about 70% of the volume of container 62, or between about 20% and about 60% of the volume of container 62, or between about 30% and about 50%, or between about 35% and about 45%, or about 40%.
[0061] The following includes a preferred range of particle sizes sprayed by the dispensing system 60. As described herein, Dv is a name based on the diameter of the volume (a measure of particle size). Thus, Dv(10) represents the 10th percentile of the particle size distribution. It should also be noted herein that the above-described particle size range covers 100% to 25% of a full tank, i.e., 100% to 25% of a full tank. In some embodiments, the Dv(10) particle size of the spray can be between about 5 μm and about 150 μm, or between about 15 μm and about 130 μm, or between about 20 μm and about 120 μm, or between about 23 μm and about 94 μm, or between about 35 μm and about 60 μm, or at least 5 μm, or at least 15 μm, or at least 20 μm, or at least 23 μm, or at least 30 μm, or at least 36 μm. In some embodiments, the Dv(50) particle size of the spray may be between about 10 μm and about 300 μm, or between about 20 μm and about 275 μm, or between about 30 μm and about 250 μm, or between about 55 μm and about 200 μm, or between about 65 μm and about 105 μm, or at least 10 μm, or at least 20 μm, or at least 30 μm, or at least 54 μm, or at least 60 μm, or at least 64 μm. In some embodiments, the Dv(90) particle size of the spray may be between about 30 μm and about 500 μm, or between about 50 μm and about 420 μm, or between about 75 μm and about 400 μm, or between about 105 μm and about 373 μm, or between about 100 μm and about 200 μm, or at least 30 μm, or at least 50 μm, or at least 75 μm, or at least 90 μm, or at least 105 μm.
[0062] In some embodiments, the spray rate measured over approximately 10 seconds may be between approximately 0.2 g / s and approximately 3.5 g / s, or between approximately 0.8 g / s and approximately 2.8 g / s, or between approximately 1.1 g / s and approximately 2.6 g / s, or between approximately 1.2 g / s and approximately 2.0 g / s, or approximately 1.7 g / s, or at least 0.2 g / s, or at least 0.8 g / s, or at least 1.0 g / s, or at least 1.1 g / s, or at least 1.2 g / s. Unless otherwise specified herein, various spray rates are measured by weighing a specific dispensing system, spraying a specific amount of time, weighing a second specific dispensing system, and calculating the spray rate based on the weight difference over the spray time. As described herein, the above spray rates cover 100% to 25% of a full can, i.e., the range from 100% full to 25% full. In some embodiments, the cone angle of the spray is measured at the apex of the spray (see...). Figure 31The spray distance, measured from the spray orifice 176 of the nozzle insert 70, may be between about 10° and about 60°, or between about 20° and about 50°, or between about 30° and about 40°, or about 35°, or at least 10°, or at least 20°, or at least 30°, or at least 35°. In some embodiments, the spray distance, measured from the spray orifice 176 of the nozzle insert 70, may be between about 5 inches (12.7 cm) and about 100 inches (254 cm), or between about 15 inches (38.1 cm) and about 70 inches (177.8 cm), or between about 27 inches (68.6 cm) and about 45 inches (114.3 cm), or about 35 inches (88.9 cm), or at least 5 inches (12.7 cm), or at least 15 inches (38.1 cm), or at least 20 inches (50.8 cm), or at least 27 inches (68.6 cm).
[0063] In some embodiments, the spray cone diameter / spray pattern diameter may be between about 0.5 inches (12.7 mm) and about 15 inches (381 mm), or between about 2.4 inches (61.0 mm) and about 6.6 inches (168 mm), or between about 3.2 inches (81.3 mm) and about 5.1 inches (130 mm), or about 4.3 inches (109 mm), or at least 0.5 inches (12.7 mm), or at least 2.4 inches (61.0 mm), or at least 3.2 inches (81.3 mm), or at least 4.3 inches (109 mm). In other embodiments, the spray cone diameter / spray pattern diameter may be between about 2.4 inches (61.0 mm) and about 12.5 inches (318 mm), or between about 5.0 inches (127 mm) and about 9.5 inches (241 mm). In some embodiments, the particle velocity of the spray can be measured at the spray orifice 176 of the nozzle insert 70 as between approximately 10 m / s and approximately 90 m / s, or between approximately 30 m / s and approximately 70 m / s, or between approximately 40 m / s and approximately 57 m / s, or at least 10 m / s, or at least 30 m / s, or at least 35 m / s, or at least 40 m / s. As described herein, the above-mentioned particle velocities cover 100% to 25% of a full tank. In a preferred embodiment, Dv(10) is between about 36 μm and about 58 μm, Dv(50) is between about 64 μm and about 105 μm, Dv(90) is between about 105 μm and about 220 μm, the spraying rate is between about 1.1 g / s and about 2.6 g / s, the potential cone angle is about 35°, the spraying distance is between about 27 inches (68.6 cm) and about 45 inches (114 cm), the spraying pattern is between about 3.2 inches (8.13 cm) and about 5.1 inches (13.0 cm), and the particle velocity is between about 40 m / s and about 57 m / s. In a preferred embodiment, the composition is 9% by volume ethanol.
[0064] Now for reference Figures 3-8 The actuator assembly 64 is shown in more detail. Figures 3-5 , Figure 7 and Figure 9 The image shows the actuator assembly 64 in its highest (unactuated) or first configuration. Figure 5 and Figure 7 The actuator assembly 64 is shown in the lowest (actuated) or second configuration. Figures 3-5 , Figure 7 and Figure 9 The unactuated or first configuration can be considered a transport or pre-actuated configuration, and the post-actuated configuration includes an actuator 68 disposed at a point between the first and second configurations, such that the actuator 68 is configured for actuation. The actuator assembly 64 includes the actuator 68, which is configured to receive at least a portion of the nozzle insert 70 into a portion of the actuator 68. In some embodiments, the actuator 68 may be made of a single piece of material, and more specifically, of a plastic material. In some embodiments, the actuator 68 may be made of a copolymer, such as a polypropylene copolymer. In some embodiments, the actuator 68 may be made of polypropylene, propylene, high-density polyethylene (HDPE), nylon, or other copolymers or homopolymers.
[0065] Specific reference Figures 3-6 The housing 66 is shown in detail. The housing 66 includes a lower edge 110 from which a continuous outer wall 112 extends upward and inward, curving toward the longitudinal axis 94 of the valve stem 86. (See reference...) Figure 3 In the front view, the left side 114 and right side 116 of the outer wall 112 curve inward and define a slightly curved outer wall 112. A racetrack-shaped front opening 118 is provided along the front side 120 of the housing 66, allowing the nozzle insert 70 to travel up and down along the front opening 118 from a first configuration (unacted) to a second configuration (fully actuated) and to dispense product through the front opening 118. The opening 118 can take various shapes and is not required to be limited to the embodiment shown herein. It should be noted that... Figure 3 The actuator assembly 64 is shown in a configuration separate from the valve stem, and the additional assembly step of pressing the actuator 68 fully positions the actuator 68 onto the valve stem 86.
[0066] refer to Figure 4 Side view and Figure 5 The rear view shows the actuator 68 extending upwards, positioned above the top wall 124 of the housing 66. (As shown) Figure 5As further shown, the rear side 126 of the housing 66 is relatively shorter than the front side 120 of the housing 66, and the top wall 124 extends between the rear side 126 and the front side 120. The top wall 124 is curved or arcuate and extends upward from the rear side 126 to the front side 120. Due to the actuator assembly 64 in... Figure 4 and Figure 5 The figure shows the actuator 68 in its highest position in these figures, and extends above the top wall 124 when viewed from the side. See details. Figure 5 A top wall 124 is shown in more detail, extending circumferentially around the actuator 68 and sloping inward and downward toward the longitudinal axis 94. The actuator 68 also includes a button 130 defining a concave top wall 132 that curves downward from left to right and from front to back. The button 130 is configured to interact with a user's thumb or finger, allowing it to be pressed to actuate the dispensing system 60. Reference Figure 6 In the side view, actuator assembly 64 is shown in a second configuration such that actuator 68 is fully depressed and not visible from the side.
[0067] Reference Figure 7 The actuator 68 shown is in a first configuration and is at least partially disposed within the housing 66. A nozzle insert 70 is also shown, disposed within a fluid passage 134 of the actuator 68. The fluid passage 134 defines a vertical conduit 136 and an inclined conduit 138 intersecting the vertical conduit 136. The vertical conduit 136 is a chamber that allows formulation to accumulate between injections and may be included to reduce material from additional, thicker portions of the actuator 68. In some embodiments, the vertical conduit 136 may be substantially shorter, and the actuator cavity 140 shown above the inclined conduit 138 may extend above the shorter vertical conduit 136. The actuator cavity 140 is an open space along the underside of the button 130.
[0068] Figure 7The document also shows a spray angle 144, which defines an angle relative to the longitudinal axis 94 and the spray axis 146. The spray angle 144 can be between approximately 45° and approximately 85°, or between approximately 50° and approximately 80°, or between approximately 55° and approximately 75°, or between approximately 60° and approximately 70°, or at most 80°, or at most 75°, or at most 70°, or at most 68°, or approximately 66°, or approximately 67°, or approximately 68°, or approximately 69°, or approximately 70°, or approximately 71°. The preferred angle ranges disclosed herein allow for the reduction of sediment by spraying the composition at an angle that increases the distance between the spray and the ground. As discussed below, the spray angle 144 can be labeled relative to an angle offset from a horizontal plane (not shown), which is orthogonally positioned relative to the longitudinal axis 94. Therefore, the angles disclosed above can be discussed with the horizontal plane as a frame of reference.
[0069] Still referencing Figure 7 The housing 66 also includes a lower opening 150 adjacent to the lower edge 110 for receiving a portion of the container 62. The housing 66 also includes a plurality of outwardly extending retaining ribs 152, stabilizing ribs 154, and alignment ribs 156 disposed along the inner surface 160 of the outer wall 112. The retaining ribs 152 are oriented substantially parallel to the lower edge 110. Any number and size of retaining ribs 152 may be included, surrounding the inner surface 160 of the actuator 68 to aid in attaching the actuator 68 to the container 62. The stabilizing ribs 154 are disposed around the inner surface 160 of the outer wall 112 to aid in the stability of the actuator assembly 64, particularly when forces are applied thereto. As described below, the alignment ribs 156 also serve as stabilizing ribs, but are positioned to aid in the alignment of the actuator 68 during assembly and to hold the actuator 68 in a non-rotatable configuration during use of the dispenser 60.
[0070] Figure 7 The diagram also shows an inner wall 162 extending downward from the top wall 124 of the housing 66. The inner wall 162 includes surfaces that interact with the actuator 68, for example, along the front side 120 of the housing 66. Figure 7 As shown, the inner wall 162 is configured to prevent upward movement of the actuator 68 by preventing upward movement of the nozzle barrel 164 of the actuator 68 when the actuator 68 is disposed within the housing 66. A plurality of retaining ribs 152 are further shown along the inner surface 160 of the housing 66, these ribs being spaced apart and, as is known in the art, assisting in attaching the container 62 to the actuator assembly 64.
[0071] Still referencing Figure 7A plurality of stabilizing ribs 154 are shown, as described above, surrounding the inner surface 160 of the outer wall 112. The stabilizing ribs 154 can provide additional structural integrity to the housing 66 to allow for increased top loads on the actuator 68. Specifically, the bottom surface of the stabilizing ribs 154 interacts with portions of the container 62 to help distribute forces applied to the upper portion of the actuator 68 around the container 62. Furthermore, alignment ribs 156 disposed along the sides and front of the housing 66 help align and position the actuator 68 in place during and / or after the capping process. This alignment assistance helps ensure that the actuator assembly 64 is correctly positioned on the valve stem 86. The alignment ribs 156 typically extend further toward the longitudinal axis 94 than the stabilizing ribs 154. In some embodiments, the stabilizing ribs 154 and the alignment ribs 156 are substantially identical in form, and there may be more or fewer ribs 154, 156.
[0072] As described above, the assembled actuator 68 is positioned and held on the container 62, i.e., the ribs 154, 156 of the actuator 68 interact with the seam 78 of the container 62 to secure the actuator 68 to the container 62 in a snap-fit manner. In this configuration, the actuator 68 of the actuator assembly 64 extends upward through the actuator 68 and protrudes through an opening 166 provided in the top wall 132 of the actuator 68. When properly positioned, the actuator 68 extends upward through the opening 166 to form a surface on which the user can apply pressure to achieve the actuation process. Furthermore, in this configuration, the valve stem 86 of the container 62 is located within the inlet port 170 of the actuator 68, thereby defining a substantially fluid seal between the surfaces of the inlet port 170 and the vertical conduit 136.
[0073] Figure 7 The image also shows an actuator 68 and a nozzle insert 70 in an assembled configuration. The actuator 68 defines a chamber axis 172 extending along a vertical conduit 136 and is connected to... Figure 2 The longitudinal axis 94 described herein extends together. When the actuator assembly 64 is placed on the container 62, the chamber axis 172 is substantially aligned with the longitudinal axis 94, and the nozzle insert 70 is inserted into the insert cavity 174 of the actuator 68. The injection orifice 176 of the nozzle insert 70 is shown positioned above or slightly below the front opening 118 of the housing 66, but once the actuator 68 is in actuated configuration, the injection orifice 176 is configured to allow atomized fluid to exit through the front opening 118. A valve seat 92 is shown within the actuator 68, defining a seat height 180, which is the height measured from the lower edge of the stabilizing rib 154 to the upper surface 182 of the valve seat 92. The valve seat 92 receives the valve of the container 62 and defines an inlet orifice 170 for the fluid passage 134 into the actuator 68 through which the product is dispensed.
[0074] Now for reference Figure 8 The diagram shows a rear sectional view of the actuator assembly 64 in its second configuration, i.e., in an actuated state. The internal aspects of the housing 66 are shown in detail, including the first or left retaining arm 186, the second or right retaining arm 188, the first or left transport lock 190, and the second or right transport lock 192. Each arm 186, 188 and transport lock 190, 192 extends downward from and is integral with the inner wall 162 of the housing 66. Furthermore, an internal cavity 194 is shown, defined as the space between the inner wall 162 and the outer wall 112 of the housing 66. Each of the arms 186, 188 and transport locks 190, 192 also includes an inwardly disposed latch or hook 196 for different purposes. For example, the latches 196 of the first and second retaining arms 186, 188 are configured to prevent over-application of the actuator 68, such as… Figure 8 As shown, the latches 196 of the first and second transport locks 190, 192 interact with the detents 198 along the actuator 68 (see...). Figure 9 (), to keep actuator 68 separate from valve stem 86 during capping.
[0075] The inner wall 162 is also shown defining a semi-circular recess 200 along the front side 120 of the housing 66, which is configured to receive the nozzle barrel 164 of the actuator 68 (see Figure 7 Therefore, the notch 200 works in conjunction with the first and second retaining arms 186, 188 to prevent the actuator 68 from deviating from the actuator profile, while the alignment rib 156 prevents the actuator 68 from rotating. Figure 8 A second height 202 is also shown, defined as the distance from the lower edge of the stabilizing rib 154 to the upper surface 182 of the valve seat 92. The second height 202 may be between approximately 20% and approximately 100% of the first height 180, or between approximately 30% and approximately 90% of the first height 180, or between approximately 40% and approximately 80% of the first height 180, or between approximately 50% and approximately 60% of the first height 180. A vertical conduit 136 for the fluid passage 134 of the actuator 68 and an inlet passage for the inclined conduit 138 leading into the fluid passage 134 are also shown. The curvature of the button 130 is also shown in detail.
[0076] Still referencing Figure 8The left arm 210 and right arm 212 of actuator 68 are shown, both disposed within the internal cavity 194 of housing 66. The left arm 210 and right arm 212 define inclined walls 214 along their outer sides, these inclined walls 214 following the contour of a portion of the outer wall 112 of housing 66. When actuator 68 is biased upward by valve assembly 84, the left arm 210 and right arm 212 of actuator 68 extend further upward into the internal cavity 194 and remain nested within it. To assemble actuator 68 onto housing 66, actuator 68 is inserted through lower opening 150, and arms 186, 188 are held through arm openings 216 within actuator 68 (see...). Figure 19 Insert until the retaining arms 186 and 188, and the latch 196, are engaged in place. Figure 8 As shown. The retaining arms 186, 188 of the housing 66 therefore bend during assembly and capture the actuator 68 once assembly is complete. Once the latches 196 of the retaining arms 186, 188 are in place along the underside of the actuator 68, i.e., translated at least as shown Figure 8 At the height shown, actuator assembly 64 can be assembled onto container 62.
[0077] Now for reference Figure 9 Another cross-sectional view of the actuator assembly 64 is shown, illustrating the transport locks 190, 192 of the housing 66 and the latch or locking tab 198 of the actuator 68. The transport locks 190, 192 retain the actuator 68 during transport, preventing it from contacting the valve stem 86 during capping and transport. During the first use of the dispenser 60, the consumer overcomes the transport locks 190, 192, and then the actuator 68 is positioned on the valve stem 86. For this purpose, the transport locks 190, 192 are configured to retain the actuator 68 until the first use of the dispenser 60. The inclined conduit 138 of the fluid passage 134 is also... Figure 9 As shown, it includes multiple stabilizing ribs 154 and alignment ribs 156.
[0078] Figures 10-16 Various aspects of the housing 66 are shown in more detail; in particular, the actuator 68 disposed therein is not shown. Various ribs 152, 154, and 156 are shown, and the front opening 118 of the housing 66 is not obstructed. See details. Figure 11 and Figure 12 The figure shows the housing width 220 and housing height 222. The housing height 222 can be between about 50% and about 150% of the housing width 220, or between about 70% and about 130% of the housing width 220, or between about 90% and about 110% of the housing width 220, or about 100% of the housing width 220. Figure 13A vertical plane 224 is shown, extending centrally through the housing 66 and through the longitudinal axis 94 of the actuator assembly 64 when it is positioned on the container 62. Arms 186, 188 are shown offset at a first angle 226 relative to the vertical plane 224, while locks 190, 192 are shown offset at a second angle 228 relative to the intersection of the vertical plane 224 and the longitudinal axis 94, the second angle 228 being smaller than the first angle 226.
[0079] Reference Figure 14 The housing 66 is shown in cross-section through a vertical plane 224. The right transport lock 192 and the right retaining arm 188 are shown in detail. A lock height 230 is shown, defining the distance from the lower edge 110 of the stabilizing rib 154 to the upper surface 232 of the latch 196 of the transport locks 190, 192. The latch 196 of the right retaining arm 188 is also shown in detail. As described above, the arms 186, 188 and the transport locks 190, 192 extend downward from the inner wall 162 of the housing 66 and partially define their internal cavities 194. Alignment ribs 156, i.e., ribs disposed along the opposite sides of the retaining arms 186, 188, are also shown. The positioning alignment ribs 156 prevent rotational movement of the actuator 68 and retain the right arm 186 and the left arm 188 therebetween. Figure 15 and Figure 16 Additional views of the interior aspects of the housing 66 are provided, including views of various ribs 154, 156 and various arms 186, 188, as well as views of transport locks 190, 192 extending downward and configured to suspend or retain the actuator 68. See details. Figure 15 The internal cavity 194 is shown as being disposed along the front side 120 and the rear side 126 of the housing 66. The internal cavity 194 is generally interrupted by the stabilizing rib 154 and the alignment rib 156, but in other cases extends around the entire housing 66.
[0080] Now for reference Figures 17-24 Actuator 68 is shown in more detail. Specifically, see reference [link to reference]. Figure 17The image shows an isometric view of the actuator 68 of the actuator assembly 64. The actuator 68 includes a button 130 defining a top wall 124 and a circular circumferential wall 236, a left arm 210, and a right arm 212, each extending outward from the button 130. As described above, the left arm 210 and right arm 212 are configured to slidably translate along opposite sides of the housing 66 between alignment ribs 156 within an internal cavity 194. Arm openings 216 are provided within the left arm 210 and right arm 212 of the actuator 68, receiving the left retaining arm 186 and right retaining arm 188 of the housing 66, respectively. The nozzle barrel 164 of the actuator 68, together with a post 240 disposed within a fluid passage 134, is shown in more detail, and the post 240, in combination with the nozzle barrel 164, defines a nozzle conduit 242 for receiving a nozzle insert 70. The front wall 244 hangs downward from the nozzle barrel 164, and the front protrusion 246 extends therefrom, and can be configured to interact with the housing 66 to prevent over-actuation of the actuator 68. A locking tab or lever 198 is further shown, which extends from the circumferential wall 236 of the actuator 68.
[0081] Now for reference Figure 18 and Figure 19 This shows the actuator depth 250 and actuator height 252. See details... Figure 18 The upper wall 132 of the actuator 68 is shown, and this upper wall 132 bends downward from its front end 254 to its rear end 256. A post 240 protruding slightly outward from the nozzle conduit 242 is also shown. A front wall 244 and a front protrusion 246 defining the foremost point of the actuator 68 are also shown. Referring now to… Figure 19 The two arms 210, 212 and the two locking tabs 198 are shown in more detail. Figure 19 The angled profiles of arms 210 and 212, as well as the symmetrical characteristics of actuator 68, are clearly shown. A hole 216 defined between the left arm 210, the right arm 212, and the button 130 is also shown, which provides a gap for the left stabilizing arm 186 and the right stabilizing arm 188 to be inserted through during the assembly of actuator assembly 64.
[0082] Now refer to Figure 20The diagram shows a top view of actuator 68, including a hole 216 into which retaining arms 186, 188 of housing 66 extend to hold actuator 68 in place. The generally circular outline of button 130 of actuator 68, and the generally outwardly sloping outlines of left and right arms 186 and 188, as well as front wall 244 and front protrusion 246, are also shown. Since actuator 68 preferably comprises a polymer, several features of actuator 68 are configured to bend during assembly of actuator assembly 64. When retaining arms 186, 188 are inserted into hole 216, the sloping outlines of left and right arms 186 and 188 allow actuator 68 to be inserted upward into internal cavity 194, during which time left and right arms 210 and 212, as well as left and right retaining arms 186 and 188, of actuator 68 are capable of bending.
[0083] Now refer to Figures 21-23 A more detailed cross-sectional view of actuator 68 is shown. The valve seat 92, its upper surface 182, the fluid passage 134 including the vertical conduit 136, the inclined conduit 138, the nozzle conduit 242, and the top wall 132 are shown in detail. See also: Figure 22 The holes 216 along the left and right sides of the actuator 68 between the left arm 210, right arm 212, and button 130 are shown in more detail. The nozzle conduit 242... Figure 23 As shown in detail, and valve seat 92 in Figure 24 More details are shown below.
[0084] See details Figure 23 Actuator 68 includes a nozzle conduit 242 configured to receive a nozzle insert 70. In the illustrated embodiment, the nozzle insert conduit 242 defines a generally cylindrical annular cavity extending generally along the spray axis 146 from the stop portion 260 to the open end 262. Also in the illustrated embodiment, the spray axis 164 is positioned generally centrally within the post 240 and arranged at an offset angle relative to the longitudinal axis 94. Furthermore, the open end 262 includes a chamfered surface 264 configured to guide the nozzle insert 70 into the nozzle insert cavity 174 during assembly. In other embodiments, other configurations are possible. For example, in some embodiments, non-cylindrical or asymmetrical profiles are possible, such as different (e.g., non-chamfered) configurations at the open end 262. Asymmetrical profiles may be useful, for example, to allow the use of a wide-angle insert to provide a wide-angle spray for foaming cleaners or other products.
[0085] In the description of features herein that relate to or include within the nozzle insert cavity 174, the terms “axial,” “radial,” and “circumferential” (and variations thereof) are used based on a reference axis corresponding to the chamber axis 172. In this respect, for example, the nozzle insert cavity 174 includes a radially outer surface 266 that extends as a generally circumferential cylinder surrounding the nozzle insert cavity 174 and defines its outer diameter 268. Similarly, a post 240 within the nozzle insert cavity 174 extends generally axially from its base near the stop portion 260 to a distal end 270 of the post 240, the distal end 270 being spaced apart from the open end 262 of the nozzle insert cavity 174 by a distance 272. The post 240 also defines a post diameter 274, and the insert cavity 174 is further defined by an insert cavity length 276.
[0086] Typically, the shape and profile defined by the post 240 and the nozzle insert cavity 174 are configured to generally conform to one or more portions of the nozzle insert 70 to facilitate reception and retention of the nozzle insert 70 within the nozzle insert cavity 174. In the illustrated embodiment, for example, the post 240 and the nozzle insert cavity 174 define a generally cylindrical shape configured to engage with corresponding cylindrical (or other) features on the nozzle insert 70. In other embodiments, for example, the post 240 and / or the nozzle insert cavity 174 may define different shapes to facilitate reception and retention of specific nozzle inserts of other shapes and sizes.
[0087] Reference Figure 24 The vertical conduit 136 defines a generally circular orifice that typically extends axially along the longitudinal axis 94. In other embodiments, for example, the vertical conduit 136 may define other cross-sectional shapes, such as rectangular, elliptical, or polygonal. The fluid passage 134 includes an inlet orifice 170 and an outlet in the nozzle conduit 242. The valve seat 92 is configured to slidably receive at least a portion of the valve stem 86 therein. (Refer again) Figure 23 Nozzle conduit 242 is disposed at the second end of inlet fluid passage 134, downstream of valve seat 92, and is configured to provide fluid communication between inlet orifice 170 and nozzle conduit 242.
[0088] Still refer to Figure 24To engage and actuate the valve stem 86, the valve seat 92 defines an inner diameter 280 that is generally larger than the diameter of the vertical conduit 136. The valve seat also defines a height 282. In operation, for example, the actuator assembly 64 can be manually or automatically displaced to force engagement between the valve stem 86 and a portion of the valve seat 92. As described above, the user can press button 130 to disengage the actuator 68 from transport locks 190, 192, which allows the valve seat 92 to fully rest on the valve stem 86. Actuation of the actuator assembly 64 disengages the portion of the valve stem 86 and the valve seat 92, displacing the valve stem 86 such that the valve assembly opens and allows product to flow from the container 62 through the valve stem 86 and into the fluid passage 134.
[0089] Now refer to Figures 25-29 The nozzle insert 70 is shown in more detail. The nozzle insert 70 is configured to at least partially insert into the nozzle insert cavity 174, thereby facilitating the dispensing of product within the container 62 to the surrounding environment with suitable fluid flow characteristics. In some embodiments, the nozzle insert 70 may be made of a plastic material. In some embodiments, for example, the nozzle insert 70 may be made of acetal (i.e., polyoxymethylene material). In some embodiments, for example, the nozzle insert 70 may be made of polypropylene, propylene, high-density polyethylene (HDPE), nylon, or other copolymers or homopolymers.
[0090] The nozzle insert 70 includes a nozzle edge 290 and a nozzle body 292 extending from the nozzle edge 290. The nozzle body 292 defines a generally annular cylinder extending generally axially between the nozzle edge 290 and a generally open insert inlet end 294. The nozzle edge 290 and the nozzle body 292 are joined at a first step 296. The nozzle body 292 defines a front or first portion 298 and a rear or second portion 300 separated by a second or chamfered step 302. In other embodiments, for example, the nozzle body 292 may define other shapes, such as rectangular, elliptical, polygonal, conical, or other shapes, if appropriate. Also as discussed below, the inlet end 294 of the nozzle insert 70 can provide an entrance to the nozzle interior cavity 304 so that the post 240 can be slidably received within the interior cavity 304. The nozzle edge 290 also defines a nozzle front wall or edge wall 306, which defines a nozzle orifice 176.
[0091] Reference Figure 27 The nozzle body 292 defines a rear portion 300 and a front portion 298, which are separated from each other by a chamfered step 302. A recess 310 is provided within a portion of the nozzle edge 290, and an outlet orifice 176 is provided within the front wall 306 of the nozzle insert 70. See details. Figure 27 and Figure 28The nozzle insert 70 defines an edge diameter 312, a first portion diameter 314, and a second portion diameter 316, wherein the edge diameter 312 is larger than the front diameter 314, and the front diameter 314 is larger than the rear diameter 316. Furthermore, the edge 290 defines an edge depth 318, the front portion 298 defines a front depth 320, and the nozzle body 292 defines a body depth 322. Further still, the rear chamfered edge 324 of the nozzle insert 70 defines a first chamfer angle 326, and the chamfered step 302 defines a second chamfer angle 328. In other embodiments, other configurations are possible.
[0092] Typically, the stepped profile of the nozzle body 292 is designed to interact with the nozzle conduit 242 of the actuator 68 to provide engagement and prevent the nozzle body 292 from over-inserting into the nozzle insert cavity 174. In the illustrated embodiment, for example, the nozzle edge 290 of the nozzle insert 70 includes a stepped configuration defining a first insert stop surface 330, which defines a radially extending surface. The first insert stop surface 330 extends generally radially inward between an outer edge surface 332 defining an edge diameter 312 and a front surface 334 defining a front diameter 314. The rear portion 300 also defines a rear surface 336, which is further stepped inward via a chamfered step 302.
[0093] like Figure 25 and Figure 26 As shown, the edge wall 306 includes a nozzle orifice 176 that extends through the edge wall 306 to provide fluid communication between the internal cavity 304 of the nozzle insert 70 and the atmosphere. (Refer to...) Figure 28 An orifice 176 extends through a marginal wall 306 from a radially extending inner edge surface 340 to a radially extending outer edge surface 342. In some embodiments, for example, the orifice diameter 344 or other aspects of the orifice 176 may be designed to achieve a desired flow pattern and / or atomization of the fluid flowing through it. For example, as described below, varying the orifice diameter 344 provides different effects or influences that are beneficial to the nozzle insert 70 used with the actuator assembly 64. In the illustrated embodiment, the orifice 176 is arranged along the jet axis 146 defined by the nozzle insert 70. In some embodiments, for example, the orifice 176 may be eccentrically arranged at the outlet end of the insert to provide a desired flow pattern and / or atomization of the fluid flow therethrough. In some embodiments, a plurality of outlet orifices may be provided.
[0094] like Figure 28As shown, the outer edge surface 342 defines a recess or indentation 310 arranged generally concentrically with the orifice 176. The indentation 310 defines a generally truncated conical recess in the outer edge surface 342, the diameter of which decreases (relative to the injection axis 146) as the recess extends axially toward the inner edge surface 340. The indentation 310 extends axially from the edge wall 306 to the outlet 350 of the orifice 176, which is located between the outer edge surface 342 and the inner edge surface 340. In other embodiments, for example, the outer edge surface 342 may define a generally flat profile without the indentation, or a profile with protrusions, or may include multiple indentations or protrusions or recesses having profiles different from those illustrated. Similarly, in other embodiments, the nozzle assembly can have other configurations to impart the desired flow characteristics to the product flow. For example, in some embodiments, the actuator may include a variety of grooves or channels leading to an outlet vortex chamber from which fluid can be transferred to orifice 176 for dispersion, as described below.
[0095] Still refer to Figure 28 Specifically, the radially inner surface 352 of the nozzle body 292 partially defines an internal cavity 304 of the nozzle body 292, which defines an inner diameter 354 that is generally constant along the internal cavity 194 between the inner edge surface 340 and the insert inlet end 294. In the illustrated embodiment, a plurality of ribs 356 extend generally radially inward from the inner surface 352 of the nozzle body 292, causing local offset along the ribs 356 from the diameter 354. In the illustrated embodiment, the nozzle insert 70 includes four ribs 356 arranged circumferentially around the inner surface 352 in increments of approximately 90 degrees. In other embodiments, for example, the nozzle insert 70 may include more or fewer ribs, or may include a plane, wherein any rib may be arranged circumferentially around the inner surface 352 in any increment as needed.
[0096] In the illustrated embodiment, each of the plurality of ribs 356 includes a ramp portion 358 and a spacer portion 360. Each of the plurality of ribs 356 extends axially along the inner surface 160 between the insert inlet end 294 and the inner edge surface 340. Each of the plurality of ribs 356 begins at the ramp portion 358 in a direction from the insert inlet end 294 toward the edge wall 306, i.e., in the opposite direction to the insertion direction. At the junction between the ramp portion 358 and the spacer portion 360, the radially inward taper of the ramp portion 358 is discontinuous, and the spacer portion 360 extends axially to the inner edge surface 340 with a substantially constant radial thickness. As also discussed below, the ribs 356 are configured to engage the post 240 of the nozzle insert cavity 174 to center or otherwise align and secure the nozzle insert 70 within the nozzle insert cavity 174.
[0097] Reference Figure 28 and Figure 29 The inner edge surface 340 of the insert 70 defines a central recess 364 and a plurality of radially extending channels 366 disposed between four radially arranged vortex features 368 extending from and integrally formed with the edge wall 306. The central recess 364 serves as a vortex chamber, which, in combination with the channels 366, is used to centrally generate a vortex of the composition at the location of the orifice 176. In the illustrated embodiment, the distribution chamber 370 of the nozzle insert defines a channel distance 372 between the parallel channels 366 and a height 374 between the ribs 356. In some embodiments, the height 374 between the ribs 356 may be designed such that the fluid flow can be appropriately distributed around the column 240 and within the nozzle insert 70 to provide a desired swirling (or other) flow pattern. The channels also define a channel thickness 376.
[0098] Reference Figure 28 A detailed cross-sectional view of the nozzle insert 70 is shown. During assembly, the post 240 of the actuator 68 is received within the internal cavity 304 of the nozzle insert 70. The post 240 engages one or more of a plurality of ribs 356 on the inner surface 160 of the nozzle insert 70. Due to the tapered shape of the ramp portion 358, the plurality of ribs 356 are configured to guide the post 240 to achieve the desired alignment within the internal cavity 304 (or, correspondingly, guide the nozzle insert 70 to proper alignment with the post 240 and the nozzle insert cavity 174). Once the post 240 has passed the engagement between the ramp portion 358 and the spacer portion 360, the spacer portion 360 serves to set the alignment of the post 240 within the internal cavity 194, and correspondingly set the alignment of the nozzle insert 70 with the post 240 and the nozzle insert cavity 174. In the illustrated embodiment, the nozzle insert 70 is substantially coaxially aligned with the nozzle insert cavity 174 after assembly. In some embodiments, the nozzle insert 70 may be otherwise aligned with the nozzle insert cavity 174 after assembly (e.g., eccentrically disposed within the nozzle insert cavity 174).
[0099] In other embodiments, other configurations are possible. For example, channels for product flow to one or more outlet orifices of the nozzle insert can be formed on the distal end of a post similar to post 240, or on other similar features, rather than on the inner wall of the nozzle insert, or, in addition to being formed on the inner wall of the nozzle insert, on edge wall 306. In some embodiments, certain flow paths of the product can be defined by raised or otherwise protruding features instead of recessed channels. In some embodiments, the outlet vortex chamber can have a different geometry than the vortex chamber, such as circular or other shapes, and the flow channels leading to the outlet vortex chamber, such as channel 366, can define tortuous or other flow paths. In some embodiments, the outlet vortex chamber can have stepped or tortuous walls leading to one or more outlet orifices.
[0100] Now refer to Figures 30-3 Section 9 will discuss the benefits of the allocation system 60 as disclosed herein. See section 6 for details. Figure 30 This shows that Figure 1 The first image of the sequence compares the spray dispersion patterns of the distribution system with those of existing distribution systems. Figure 31 It is the second image in the sequence. Figure 32 It is the third image in the sequence. Figure 30 The empty state is shown, that is, before the actuation system of multiple distribution systems has been actuated. Figure 31 A first state is shown, illustrating a first jet pattern 400, a second jet pattern 402, and a third jet pattern 404. The first jet pattern 400 reflects the jet pattern generated by the distribution system 60 disclosed herein, while the second jet patterns 402 and the third jet pattern 404 illustrate jet patterns of prior art jets. Jet patterns 400, 402, and 406 are... Figure 32 The text further illustrates that it is in a second state, which occurs after the first state.
[0101] Figures 30-32 The images in the sequence were taken at the same time during the spraying process; therefore, spray patterns 400, 402, and 406 depict multiple sprays at the same time point after the initial actuation of multiple actuators of the product dispensing system. As shown, the first spray pattern 400 and the second spray pattern 402 both dispense the jet at an angle above the horizontal direction (the product dispensing system 60 sprays at an angle of approximately 22° above the horizontal direction or at an angle of 68° to the vertical direction), while the third spray pattern 404 dispenses the jet in a direction substantially perpendicular to the horizontal direction. To achieve preferred settling, it has been determined that having an angle greater than 0 degrees to the horizontal direction is advantageous, as mentioned above regarding various preferred ranges. Furthermore, as Figure 32As shown, in the second state, the first jetting mode 400 includes droplets that are distributed relatively further than those in the second jetting mode 402. The increased distance is at least in part due to the use of compressed gas, the altered composition, and the increased pressure within container 62, as disclosed herein. The increased jetting distance of dispenser 60 provides reduced settling, as illustrated in the figures and tables provided below.
[0102] Referring to Table 1 below, various aerosol sprays were simulated in a 6' x 9' bathroom to determine the perceived fragrance coverage after 10 minutes. Simulations were performed using full cans and cans filled to 25% capacity. Therefore, these two simulations tested the perceived fragrance coverage at the beginning and end of the lifespan of each aerosol can. As shown in Table 1 below, for both full and 25% capacity cans, the aerosol from dispensing system 60 outperformed other prior art aerosols in terms of perceived fragrance coverage. Specifically, after 10 minutes, the aerosol from dispensing system 60 filled approximately 96% of the bathroom when using a full can, and approximately 92% when using a 25% capacity can. Therefore, the aerosol from dispensing system 60 has a better fragrance than prior art aerosols.
[0103]
[0104] Table 1
[0105] Figure 33 This is a graph illustrating the use of a nozzle insert 70 with a variable orifice diameter of 344. Figure 1 A comparison of the perceived fragrance coverage at 100% full using the dispensing system 60 and prior art dispensing systems. The data reflecting 90PP, 102PP, and 110PP show the difference in fragrance coverage over time compared to... 1. 2. It offers better fragrance coverage. The 90PP, 102PP, and 110PP dispensers all include a dispensing system 60, the only difference being the use of nozzle inserts 70 with different orifice diameters. The 90PP dispenser includes the smallest orifice diameter 344, while the 110PP dispenser includes the largest orifice diameter 344. (The last sentence appears to be incomplete and unrelated to the preceding text.) Figure 33As shown, the orifice diameter 344 of the nozzle insert 70 helps to increase the fragrance coverage. Furthermore, when compared to prior art dispensing systems, the product dispensing system 60 shows improved fragrance coverage in all three data points. Therefore, it has been determined, in conjunction with other aspects of the product dispensing system 60 disclosed herein, and more specifically, that a particular orifice diameter 344 provides increased coverage and reduced sedimentation, that the nozzle insert 70 disclosed herein is advantageous in providing increased fragrance coverage and thereby reducing sedimentation. The orifice diameter 344 may be between about 0.310 mm and about 0.410 mm, or between about 0.335 mm and about 0.385 mm, or between about 0.350 mm and about 0.370 mm, or about 0.360 mm.
[0106] Figure 34 Another graph shows a comparison of perceived fragrance coverage, but at 25% of the full tank for dispensing system 60 and prior art dispensing systems. Figure 34 The graphic shows the reflection and Figure 33 The same allocation system data, but without additions. 2. Distribution system. For example... Figure 33 As shown, the fragrance coverage of the dispensing system starts from when the container is full. Figure 34 Data reflecting 90PP, 102PP, and 110PP indicate that, over time, the fragrance coverage of 90PP, 102PP, and 110PP is higher than that of 110PP. and 1 is better. The 90PP, 102PP, and 110PP dispensers all include a dispensing system 60, the only difference being the use of nozzle inserts 70 with different orifice diameters. The 90PP dispenser includes the smallest orifice diameter 344, while the 110PP dispenser includes the largest orifice diameter 344. (The last sentence appears to be incomplete and possibly refers to a different product.) Figure 34 As shown, the orifice diameter 344 of the nozzle insert 70 helps to improve fragrance coverage. Furthermore, when compared to prior art dispensing systems, all three data points of the product dispensing system 60 shown provide increased fragrance coverage. Therefore, it has been determined that, in combination with other aspects of the product dispensing system 60 disclosed herein, the nozzle insert 70 disclosed herein is advantageous in providing increased fragrance coverage, thereby reducing settling, even when there is a small amount of product in the container, i.e., when approaching the end-of-life (EOL) of the product dispensing system.
[0107] Figure 35 It shows Figure 1 A graph comparing the percentage of settling at various spray heights between the current distribution system and existing distribution systems. Figure 35 The data is further shown in Tables 2 and 3 below, which illustrate the data generated by... Figure 1The experimental results of the "%Fallout" settlement percentage test were shown for the distribution system 60 and various prior art distribution systems at two different heights, namely 4 feet (122 cm) and 5 feet (152 cm).
[0108]
[0109] Table 2
[0110]
[0111] Table 3
[0112] As described herein, the %Fallout test measures the amount of aerosol liquid that falls to the ground after it has been sprayed into the air. To perform this test, a 3x6 (3×6) scale array is placed on the ground, and a matrix is placed on the scale to define the spray surface. Before testing each product, the product is weighed to determine the initial weight (Wi). The product is then sprayed for 5 seconds at a specific height, i.e., 4 or 5 feet, in the direction of the matrix and the scale. After the aerosol spray has settled, the weight of the liquid or sediment on the matrix (Ws) is recorded, and the product is weighed again to determine the final weight (Wf). The difference between the initial weight (Wi) and the final weight (Wf), along with the weight of the liquid on the matrix (Ws), is used to determine the %Fallout (see equation below). After determining the %Fallout (settling percentage), the matrix is changed, and the test is repeated three times for each product at each height. The "% Fallout" data shown in Tables 2 and 3 above are the average of three tests conducted on each product at each height.
[0113]
[0114] As shown in Tables 2 and 3 above, the dispensing system 60 produces the least amount of "% Fallout" (settling percentage) compared to other prior art products. In some cases, the "% Fallout" (settling percentage) of the components of the dispensing system 60 is almost half that of prior art examples. Therefore, Figure 1The dispensing system 60 shown allows a higher percentage of aerosol fragrance to remain suspended in the air rather than fall to the ground. This allows consumers to spray less product to produce the desired fragrance strength, thereby increasing product lifespan. In some embodiments, the percentage of settling of the dispensing system 60 at 4 feet (122 cm) can be between about 10% and about 50%, or between about 15% and about 40%, or between about 23% and about 36%, or about 28%, or at least 10%, or at least 15%, or at least 23%, or at least 28%. Furthermore, the percentage of settling of the dispensing system 60 at 5 feet (152 cm) can be between about 10% and about 50%, or between about 15% and about 40%, or between about 22% and about 33%, or about 26%, or at least 10%, or at least 15%, or at least 22%, or at least 26%.
[0115] Now refer to Figure 36 and Figure 37 This shows the comparison Figure 1 The graphs show the total settling mass of the original distribution system and the existing distribution system at 100% full tank and 25% full tank, respectively. Figure 36 and Figure 37 The graph shows a simulation of the settling mass, i.e., the settling mass generated during the spraying of each distribution system ten minutes after each distribution system has been actuated. Figure 36 and Figure 37 The graphs provide further data to demonstrate that the dispensing system 60 achieves reduced settlement when tested under the same conditions as prior art dispensing systems. Furthermore, although different types of nozzle inserts 70 with different orifice diameters 344 were used, all three nozzle inserts 70 performed better than prior art and produced reduced settlement.
[0116] Figure 38 It is a line graph, showing Figure 1 A comparison of the average spray pattern diameter and the percentage of remaining product in the container between the current and existing distribution systems. (Curve) Figure 38 The data shows that the dispensing system 60 disclosed herein maintains a consistent average spray diameter throughout its entire service life, while prior art dispensers exhibit a spray pattern where the diameter decreases over time. Therefore, another beneficial effect of the dispensing system 60 disclosed herein is that it maintains a relatively constant spray diameter throughout its entire service life, providing users with a consistent user experience, and eliminating the need for users to modify the spray volume to achieve the desired fragrance coverage as the amount of product within the dispenser decreases.
[0117] Therefore, embodiments of this disclosure provide an actuator assembly or nozzle insert for a product dispensing system. In some embodiments, the improved actuator assembly or nozzle insert can provide improved manufacturability and reduce defects that may occur during assembly (or use) due to overcompression of the nozzle insert. For example, some embodiments of the invention provide a nozzle insert, and a corresponding nozzle insert cavity in the actuator of an actuator assembly, having a first stop portion and a second stop portion to mitigate the overcompression effect of the nozzle insert. This can, for example, correspondingly reduce (e.g., eliminate) the likelihood of defects forming in the actuator assembly during assembly.
