(31) FIGS. 1-16 illustrate one embodiment of a charging case 100 having a housing 200 and a cover 300 for receiving and storing a power toothbrush 400 (FIG. 24). The powered toothbrush 400 generally comprises a handle 410 and brush head 420, one embodiment of which is shown with reference to FIGS. 17-26, the details of which will be described later. FIGS. 25 and 26 illustrate embodiments of a powered toothbrush and case system including toothbrush components 410, 420 stored within case 100, with toothbrush component 410 being charged while the case 100 is connected to a power source. In the illustrated embodiments, the power source can be a power outlet (FIG. 25), computer (FIG. 26) or the like, with other power sources being possible. The charging of the toothbrush component 410 while seated within the case 100 is apparent through the illumination 419 of an indicator 418 on the toothbrush component 410, which illumination 419 is evident while the cover 300 is open (FIG. 25) or closed (FIG. 26). In the illustrated embodiment, once the toothbrush component 410 is charged, the components 410, 420 are removed from the case 100 and assembled (FIG. 24) prior to use. After use, the components 410, 420 are disassembled and stored within the case 100, and then if desired the case 100 is connected to a power source for charging the component 410. The powered aspect of the powered toothbrush can come in any form or type of benefit delivery, where the powered toothbrush may, for example, vibrate when activated, or deliver a therapeutic active, or emit beneficial or sanitizing light, or other types of benefits, with the present disclosure not being limited to any type of powered delivery or benefit, or any type of head, bristle, neck or stem configuration. Details of each component and aspects of the case and toothbrush system will now be described.
(32) As shown in FIGS. 1-16, the case housing 200 further comprises a top end 210, a bottom end 220, a front surface 230, a rear surface 240, a side surface 250 having a charging port 252, a longitudinal axis 260 (FIG. 1), and an interior 270. A charger system 280 is provided for charging a power toothbrush 400 that is stored in the case 100 when a power source is connected to the housing 200 through the port 252 by a power cord 282 or the like (see FIGS. 3 and 25-26 for example). Additional details of the interaction between the power toothbrush 400 and the case 100 will be described below. In one embodiment, the port 252 can include a mini-USB connection, although connectors of other sizes and types are possible, and the charger 280 is an induction charger, although other types of chargers are also possible. The charger system 280 can also comprise an internal power source, such as a battery (not shown), that would render unnecessary the need to connect the case 100 to an external power source. Alternatively, the case 100 may include a charging system that can operate with one or both of an internal or external power source. Other charging variations are possible. Furthermore, the port 252 may be positioned in a location relative to the housing 200 other than as shown in the accompanying drawings, and may have an optional protective and/or waterproof cover as shown.
(33) The cover 300 further comprises a top end 310 with a vent 312, a bottom end 320, a front surface 330, a rear surface 340, a side surface 350 with gripping tabs 352 for manipulating the cover 300 relative to the housing 200, a longitudinal axis 360 (FIG. 15), and an interior surface 370 (FIG. 9). While the vent 312 and gripping tabs 352 are preferably positioned relative to certain features of the cover 300, it will be appreciated that the vent 312 and/or gripping tabs 352 could be located elsewhere on the cover 300, or could be optional if desired.
(34) In the illustrated embodiment, the housing interior 270 further comprises at least a first storage location 271 for receiving a first component 410 (FIGS. 17-26) of a powered toothbrush 400, the first storage location 271 having a storage chamber 272 at least partially surrounded by chamber walls 273 for receiving a portion of the first component 410, and a floor 274 (FIG. 13) upon which the first component 410 is seated while being stored and potentially charged. The housing interior 270 further comprises a second storage location 276 for receiving a second component 420 (FIGS. 24-26) of a powered toothbrush 400, the second storage location 276 having a storage chamber 277 for receiving a portion of the second component 420, and a floor 278 (FIG. 13) having a mounting pin with indexing tabs 279 thereon upon which the second component 420 can be mounted for storage. In the illustrated embodiment, the first and second components 410, 420 of the powered toothbrush 400 are stored separately within the storage locations 271, 276 respectively (FIGS. 25-26), and are then combined or attached to each other (FIG. 24) prior to use. In certain situations it may be preferable to store a powered toothbrush in a case as a single unit (not shown), in which case there would only be provided a single storage location (not shown). Other configurations are possible.
(35) In the illustrated embodiment, the first component 410 of the powered toothbrush 400 further comprises a handle 412 having a slot 413 (FIG. 21), a stem 414 with indexing tabs 415 for receiving the second component 420 or brush head 420 in the illustrated embodiment, a power switch or button 416, and an indicator 418 that preferably illuminates 419 (FIGS. 25-26) when the powered toothbrush 400 is being charged while stored within the case 100. More specifically, the handle 412 is preferably slidably received within the storage chamber 272 with a portion of the storage chamber walls 273 partially enclosing the handle 412 to prevent the handle 412 from falling out of the chamber 272 unless the case 100 is nearly or completely inverted. The handle slot 413 is seated upon a charging pin 275 (FIG. 13) along the chamber floor 274 that inductively charges the toothbrush 400 when power is delivered to the case 100 preferably through the port 252 as described previously. The handle 412 is axially aligned within the chamber 272 through the engagement of the handle slot 413 with the charging pin 275, and the proximity of the two mating components 413, 275 inductively delivers the charge to the toothbrush handle 412. The chamber walls 273 and the preferably non-circular periphery of the toothbrush handle 412 (see FIGS. 20-21, wherein the periphery has mildly flattened features) are preferably configured to substantially prevent the handle 412 from freely rotating within the chamber 272, and so that the indicator 418 preferably remains oriented toward the front surface 230 of the housing 200 and thereby visible while the handle 412 is seated within the chamber 272 (FIG. 25).
(36) In the illustrated embodiment, the second component 420 of the powered toothbrush 400 (see FIG. 24) is an attachable replacement or refill head configured to be removably coupled to the stem 414 of the first component 410 of the powered toothbrush 400. The second component 420 further comprises a bristle field 422 at the end of a hollow neck portion 424 having indexing slots 426 (FIG. 24) that are sized and configured for engagement with both the indexing tabs 415 on the stem 414 and the indexing tabs or seat 279 along the floor 278 of the second storage chamber 277. The indexing tabs 279 also function to orient the bristle field 422 within the interior 270 so that the bristle field 422 is facing the handle 412 and is oriented adjacent the vent 312 (FIG. 26) so that the bristle field 422 is closest to a location that allows residual moisture on the bristle field 422 to escape from within the interior 270 when the cover 300 is closed.
(37) In a preferred embodiment as shown in FIG. 26, the cover 300 is configured to substantially obfuscate the interior 270 of the case 100 so that the components of the interior 270 are not readily discernible when the cover 300 is closed. The cover 300, however, is also preferably sufficiently light-transmissive to communicate through the cover 300 the presence of an indicator 418 or an indicator light 419 from within the interior 270, so that the user can receive positive confirmation that the toothbrush is being properly charged without having to open the cover 300. In a preferred embodiment with the indicator 418 being oriented outward while the toothbrush handle 412 is stored within the storage location 271, the indicator 418 would preferably be visible or recognizable via illumination 419 through the closed cover 300 (FIG. 26) while the toothbrush is being charged through a power cord 282 connected to the port 252 in the case 100, even though the details of the remaining components of the toothbrush 400 might not be discernible through the cover 300. This enables a user to quickly and discretely confirm that the stored toothbrush is being properly charged.
(38) In an alternative embodiment, an indicator could be provided on the case 100 itself or an aspect of the case 100, rather than on a removable component stored within the case 100, such that the indicator communicates that the case is experiencing a powered or charging condition, which would thereby indicate that the component stored within the case is also experiencing a powering or charging condition. For example, an indicator light may be disposed on the housing 200, such as along a portion of the interior 270 between the first and second storage locations 271, 276. Alternatively, discrete portions of the interior, such as an entire peripheral edge of the housing adjacent the connection between the housing and the cover, may illuminate during a charging or powered condition. Other indicator manifestations and locations are possible. While in the preferred embodiment the cover 300 is substantially translucent, other material properties and compositions are possible. For example, the cover 300 may be substantially opaque or completely opaque, or completely transparent if desired. Furthermore, while it is preferred that the entirety of the cover 300 is substantially translucent for ease of manufacturing for example, it may be more desirable in certain situations if only a portion of the cover 300 is substantially light-transmissive such as, for example, in an area adjacent an illuminated indicator area within the interior 270.
(39) In the illustrated embodiment, the cover 300 is attached to the housing 200 by a hinge 212 defined between the top end 210 of the housing and a location 314 along the cover 300 that is spaced from the top end 310 of the cover 300. The hinge 212 is oriented along an axis 290 (FIG. 4) that is transverse to the longitudinal axis 260 (FIGS. 1 and 4) of the housing 200 with the cover 300 being movable relative to the housing 200 from a closed position (FIGS. 1-8) that occludes the housing interior 270, to a fully-open position (FIGS. 9-16) that exposes the housing interior 270. The hinge 212 also protrudes relative to the rear surfaces 240, 340 of the housing 200 and cover 300, such that when the case 100 is placed in a closed condition on a support surface (not shown) with the rear surfaces 240, 340 adjacent the support surface, the top end 310 of the cover is elevated relative to the bottom end 220 of the housing 200, or in other words the case 100 becomes inclined relative to the support surface by virtue of the case 100 resting on the hinge 212. This incline reinforces the downward positioning of the handle 412 within the chamber 272 and urges the handle 412 into the chamber 272, which helps to maintain the inductive charging contact between the handle slot 413 and chamber pin 275 while the handle 412 is stored within the case 100.
(40) The displaced positioning of the hinge 212 relative to the top end 310 of the cover 300 creates an additional benefit in that when the cover 300 is in a fully-opened condition, the rear surface 340 of the cover 300 adjacent the hinge 212 impacts the upper end of the rear surface 240 of the housing 100 (FIGS. 15-16) and prevents over-rotation of the cover 300 relative to the housing 100.
(41) While various surfaces, locations and orientations of the housing 200, cover 300 and interior 270 have been described to correlate with the illustrated figures, it will be appreciated that the housing, cover and interior can be arranged and configured in a manner other than as shown in the appended drawings, without departing from the scope of the present disclosure.
