Sunless tanning, also known as artificial tanning, UV-free tanning, airbrush tanning, or spray tanning, is becoming increasingly popular. Sunless tanning utilizes various chemical compositions that are applied manually or automatically to all or portions of the human body. However, manually applying chemical compositions to the human body frequently results in an uneven coating of the chemical composition. Further, many automatic devices are not comfortable or convenient for a user, and often still fail to apply the chemical composition evenly.
Implementations described and claimed herein address the foregoing problems by providing a sunless tanning device that applies an even coat of a chemical composition while being comfortable and convenient for a user.
Other implementations are also described and recited herein. Further, while multiple implementations are disclosed, still other implementations of the presently disclosed technology will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative implementations of the presently disclosed technology. As will be realized, the presently disclosed technology is capable of modifications in various aspects, all without departing from the spirit and scope of the presently disclosed technology. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not limiting.
Aspects of the presently disclosed technology involve a sunless tanning device that applies an even coat of a chemical composition such as a cosmetic composition while being comfortable and convenient for a user. As can be understood from a perspective view shown in
In one implementation, the sunless tanning device 100 includes an opening 102 through which a user may step to enter the sunless tanning device 100 for use. The opening 102 is defined, in part, by sides 104, a bottom 106, a top 108, and a back 110. The semi-enclosed opening 102 enhances the overall experience of the user. Many automatic devices are completely enclosed, which tends to create a claustrophobic feeling for the user. The opening 102 allows the user to be able to see out of the sunless tanning device 100 during use, thereby reducing or eliminating any claustrophobic feelings. The opening creates the appearance of more space for a user, which increases the overall comfort of use, but does not inhibit the deliver of the chemical composition.
In one implementation, as shown in

In one implementation, a bar 302 moves vertically along a frame 304. Positioned on the bar is a plurality of the nozzles 306, which are connected to a plurality of pumps (not shown). In one embodiment the bar 302 includes three (3) nozzles 306. In another embodiment the bar 302 includes at least two nozzles 306. In another embodiment the bar 302 includes four (4) nozzles 306. In another embodiment the bar 302 includes five (5) or more nozzles 306. In one implementation, as described with respect to
As described herein, atomization of the chemical composition is impacted by pressure and volume. Because the chemical composition has to overcome the forces of gravity when traveling from the pumps through the nozzles 306, if the chemical composition is applied at the same pressure as the bar 302 moves from the top 108 to the bottom 106, a greater volume of the chemical composition will be applied on the lower portions of the user's body than the top portions, which results in an uneven application. Accordingly, to ensure an even application, the application assembly 300 delivers a constant volume of the chemical composition as the bar 202 moves from the top 108 to the bottom 106. To overcome the forces of gravity, the chemical composition is delivered using a gradient pressure. Specifically, the application assembly 300 delivers the chemical composition at a relatively higher pressure when the bar 302 is positioned near the top 108 and a relatively lower pressure when the bar 302 is positioned near the bottom 106. By varying the pressure an even constant volume of the composition is delivered through the nozzle.
The volume of a composition delivered through a nozzle will be constant for a cycle of the bar 302 from the top 108 position to the bottom 106 position and return to the top 108. In another embodiment the volume of the chemical composition is variable for a cycle with more or less chemical composition delivered at defined time intervals or sections. The volume of a chemical composition delivered is from 0.1 oz/sec to 1.0 oz/sec. In another embodiment the volume delivered is 0.25 oz/sec to 0.44 oz/sec.
Varying the volume and/or the pressure at which the chemical composition is delivered through the nozzles 306, impacts the spray pattern of the atomized chemical composition. Additionally, altitude and/or viscosity of the composition can impact spray pattern and volume delivered related to pressure. For example, a higher volume of the chemical composition creates a tighter fan shaped spray from the nozzles 306, and a lower volume of the chemical composition creates a wider fan shaped spray from the nozzles 306. Additionally, varying the volume and/or the pressure affects the atomization and application of the chemical composition. For example, the volume and/or pressure may be further modified, without limitation, to reduce overspray, reduce consumption of the chemical composition, increase the proportion of the chemical composition reaching the user, and increase the uniformity of the application of the chemical composition on the user. In one embodiment the pressure is between 0.1 psi and 7 psi. In another embodiment the pressure is between 2.5 psi and 5 psi. Further, in one implementation, the pump pressure is monitored in substantially real time to ensure the pressure of the pumps remains near the target pressure. The sunless tanning device 100 may include, for example, transducers to monitor the pressure of the pumps. If the pressure is outside operational parameters, the pressure of the pumps may be adjusted.
A motor 310 is operably connected to the bar 302 to move the bar 302 vertically along the frame 304. The motor 310 controls the speed at which the bar 302 moves, which affects the volume of chemical composition that is sprayed on the user. Some automatic devices varying the volume or concentration of the chemical composition applied to the user to achieve different levels of tan shades or darkness. As described herein, pressure and volume affect the atomization of the chemical composition, and proper atomization is important to whether the chemical composition is uniformly applied to the user. Further, changing the concentration of the chemical composition creates a risk that the color will not look natural or as intended. Accordingly, rather than varying the pump pressure or volume or changing the concentration of the chemical composition to provide different levels of tan shades, the speed of the motor 310, and thus the bar 302, is varied. Specifically, different levels of tan shades are achieved through regulation of the time it takes for the bar 302 to travel the approximate length of the frame 304 from the top 108 to the bottom 106. For example, a level one (lighter) tan may be correlated to a time of six seconds for the bar 302 to travel; a level two tan may be correlated to a time of seven seconds, and; a level three tan (darker) may be correlated to a time of eight seconds. However, other times and levels are contemplated.
In one implementation, before the bar 302 begins moving, a voice prompt provides the user verbal instructions, including, without limitation, a countdown to advise the user when spray will begin. The voice prompt warns the user to hold their breath and close their eyes. The voice prompt further instructs the user on how to position their body relative to the nozzles 306. Many automatic devices force the user to stand in multiple positions to reach a substantial portion of the user's body, which often results in frustration and mistakes. The presently disclosed technology addresses these problems with the positioning of the nozzles 306, as described with respect to
The bar 302 moves in a cycle from a top 108 position to a bottom 106 position. A cycle is considered complete when the bar 302 moves from the top 108 to bottom 106 and then returns to top 108 position. In another embodiment the cycle can include more than a single (multiple passes) from top to bottom to top. The device 100 is designed to deliver a total amount of chemical composition during a cycle. This amount is from 0.1 oz to 5 oz. In another embodiment the amount is 1.5 oz to 3.5 oz.
In addition to reducing possible sources of error based on body positioning, the application assembly 300 includes safety features to detect and respond to possible safety hazards (e.g., a user passing out during use). In one implementation, the sunless tanning device 100 includes one infrared (IR) sensor near the bottom 106 and one IR sensor on an underside of the bar 302 to detect ingress by the user during movement of the bar 302. If all or a portion of the user's body passes under the bar 302 during movement, the IR sensors will detect a potential safety hazard. In response, the motor 310 will stop and move bar 302 back to towards the top 108. Further, the motor 310 may include a load sensor, and if a high current is detected, the motor 310 will stop and move bar 302 back to towards the top 108. In some implementations, after a potential safety hazard is detected, the voice prompt may also notify the user via voice message, visual message, or other message that help is on the way.
Many automatic devices merely spray the chemical composition on the user without any comfort features. For example, many users get cold during application of the chemical composition. Some automatic devices include heaters. However, the heaters often do not adequately direct the heat at the user or the heat is removed too quickly to warm the user during application. Additionally, the chemical composition generally takes a while to dry. Accordingly, the presently disclosed technology provides a comfort forced air drying system.
In one implementation, the bar 302 includes one or more heaters 308 to warm and/or dry the user during and/or after application of the chemical composition and to ensure the user remains at a comfortable temperature during user. Prior to a user entering the sunless tanning device 100, the heaters 308 pre-heat the sunless tanning device 100, so the user is comfortable during the entirety of use. While the bar 302 is moving and the nozzles 306 are propelling the chemical composition, the heaters 308 direct forced heated air at the user. In one implementation, the heaters 308 are positioned along the bottom of the bar 302 such that the heated air travels with the atomized chemical composition. For example, the heaters 308 may be positioned in a separate plane from the nozzles 306 or below each of the nozzles 306. The heaters 308 can deliver heated air either prior to or after the chemical composition is delivered. The heaters 308 direct the heated air at a downwards angle relative to the spray patterns of the nozzles 306 to reduce air disruption and vortices impacting the spray patterns. The heaters 308 heat the user's body during delivery of the chemical composition to provide added comfort for the user. Further, the heaters 308 heat the atomized chemical composition after release from the nozzles 306 to dry the chemical composition on the user. While the heaters 308 are providing heated forced air, the exhaust unit 204 is turned off to ensure that the heated air is not removed from the sunless tanning device 100 while the chemical composition is being applied.

In addition to the plurality of holes 504, in one implementation, the back panel 502 includes closed section or sections without holes 504, the first closed surface 602 and a second closed surface 604 are configured to improve airflow and delivery of the cosmetic composition to the user. The position of the closed surfaces 602 and 604 on the back panel 502 correlate to body parts of the user, such as the head and legs, respectively. The positioning of the closed surfaces 602 and 604 relative to the holes 504 pull the air from the center of the body and around the upper body parts and the lower body parts to improve the uniformity and quality of the coating of the chemical composition while removing enough residual spray to provide a comfortable user experience.
For example, one or more capacitors may be positioned on, in, or near the containers 704 corresponding to different capacity gradients of the containers 704 a range of fluid levels to determine whether the containers 704 are full or close to low. In another implementation, a session count is used to monitor the fluid level of the containers 704, for example, based on the number of sessions since the containers 704 were last replaced. Specifically, the sunless tanning device 100 correlates the number of sessions between when each of the containers 704 is placed in the sunless tanning device 100 and when each of the containers 704 is replaced to predict when the fluid in the container 704 will be low. In still another implementation, sensors that are in direct communication with the fluid in the containers 304 are used to measure fluid levels. Other fluid level sensors are also contemplated. Measuring the fluid levels will also correlate to the total number of sessions administered to a user.
