[0020] A. Exemplary Devices and Methods References to "floss" or "dental floss" in this disclosure are intended to encompass various types of interdental and interproximal cleaners, including, but not limited to, cleaning strands such as nylon, monofilament, multifilament threads, yarns, traditional dental floss (e.g., waxed dental floss such as Oral-B™ Glide™, or unwaxed dental floss such as GUM Butler Weave), and combination rigid threaders and floss products (e.g., ProxySoft™ Bridge and Implant Cleaner or Oral-B™ Glide™ Pro-Health™ Threader Floss).

[0021] References in this disclosure to a "threader with floss" or a "threader and floss combination" or a "threader floss" or a "rigid interproximal insert" mean (1) a floss characterized by having a rigid or less flexible threader portion (e.g., for insertion between teeth or other types of interproximal locations) and a flexible floss and / or brush portion (e.g., ProxySoft™ Bridge and Implant Cleaner) and / or (2) a rigid threader tool combined with and / or connected to a strand of conventional floss (e.g., used to insert and then pull conventional floss through an interproximal location) (e.g., DenTek™ floss threader).

[0022] According to various embodiments of the present invention, a device for delivering and / or applying threader floss and other types of interdental cleaners is provided. The device may be most effective with a combination of threader and floss, but in some embodiments, it may also be useful to apply other types of dental floss. According to some embodiments, the device has a curved front end from which the floss is delivered, advantageously allowing a user to orient the curved front end of the device to guide the insertion of the floss to a desired interproximal location (e.g., between two teeth). In one example, a user may hold the device in their right hand to deliver floss at an interproximal location outside the user's teeth on the left side, and therefore may want the curved end of the delivery device to curve toward the user's right side when held in the right hand. In such a case, the user may hold the floss delivery device so that the thumb of the user's right hand is in contact with the floss and rotate the floss advancement wheel with the thumb while pressing the floss against the bottom side of the wheel to advance the floss into the floss receiving port on the lower side of the device and thus out of the delivery opening at the front end.

[0023] In another example, the user may elect to continue holding the device in his / her right hand and desire to deliver floss at an interproximal location on the inside of the user's teeth on the left side, and therefore desire the curved end of the delivery device to curve generally toward the user's left side when held in his / her right hand. In such a case, the user may insert floss through the other (upper) floss receiving port and hold the floss delivery device such that the thumb of the user's right hand contacts the floss and rotates the wheel with the thumb while pressing the floss against the top surface of the floss advancing wheel to advance the floss into the upper floss receiving port of the device.

[0024] Certain features according to certain embodiments of the present invention are described below with reference to the drawings. With reference to Figure 1, floss threading device 100 includes handle 102 and floss threading guides 104a (upper) and 104b (lower) for engaging the floss with wheel 106 to guide the floss into either floss-receiving port 110 (e.g., upper) or floss-receiving port 112 (e.g., lower). According to certain embodiments, wheel 106 is configured within floss threading device 100 so as to be accessible to a user (e.g., for advancing the floss using wheel 106).

[0025] Both floss-receiving port 110 and floss-receiving port 112 direct inserted floss (not shown) into the interior (interior not shown) of end 114, which is connected to both floss-receiving port 110 and floss-receiving port 112 such that floss advanced into either of them enters end 114. End 114 provides a passageway for inserted floss as it is advanced into hole or delivery opening 116 and dispensed from the opening (e.g., at an interproximal location, such as between the user's teeth).

[0026] According to some embodiments, floss-receiving ports 110 and 112 may be separated by a dividing portion (not shown). In other embodiments, floss-receiving ports 110, 112 may not be structurally separated and may be defined by the manner in which the floss is inserted (e.g., by passing the floss over or under wheel 106).

[0027] In one embodiment, wheel 106 includes one or more ridges 107 to improve engagement of the user's fingers or thumb with wheel 106 when rotating wheel 106. In some embodiments, the wheel may include a groove or channel 108 to hold the floss such that the floss engages wheel 108 and is advanced by the action of the user (e.g., using the thumb or fingers) by rotating the wheel.

[0028] According to some embodiments, the floss delivery device does not include a wheel, but is configured with a surface (e.g., integral with the handle 102) against which a user can press the floss to advance it along the longitudinal axis into one of a plurality of floss receiving ports.

[0029] According to some embodiments, the floss delivery device may include three or more floss receiving ports to provide additional options for comfort and ease of use, depending on the user's personal preferences.

[0030] According to some embodiments, the floss delivery device may be formed of any suitable material suitable for handling by a user and for application of floss within the user's mouth and other interproximal locations. For example, plastic, nylon, metal, wood, and / or any combination of such materials may be used to form the floss delivery device. An exemplary exploded view of a floss delivery device is described below with respect to FIG.

[0031] FIG. 2 shows another view of the floss threading device 100 of FIG. 1. As shown in FIG. 1, the wheel 106 may be accessible to a user on a first side of the floss delivery device 100 (e.g., the top side, as shown in FIG. 1), and as shown in FIG. 2, the wheel 106 may also be accessible on a second side of the floss delivery device 100 (e.g., via a port on the opposite side of the first side, as shown in FIG. 2). Thus, a user may use the wheel 106 to advance floss through the floss receiving port 112, into the end 114, and out the delivery opening 116. Thus, a floss delivery device 100 configured with dual floss receiving ports 110, 112 and dual access to the wheel 106, on either side of the floss delivery device 100, allows a user to choose how to introduce floss into the floss delivery device depending on the user's preference, comfort, and ease of use for a particular floss application.

[0032] 3 shows a close-up view of a portion of an exemplary floss delivery device 300, according to some embodiments. As shown in FIG. 3, floss delivery device 300 may include a handle 302 connected to a floss threading guide 304. Floss threading guide 304 (also referred to as a floss "loop") defines a guide opening 305 for optionally receiving floss 309 that a user wishes to apply using floss delivery device 300. Guide opening 305 may advantageously aid in aligning floss 309 for insertion into floss receiving port 310 and / or for placing floss 309 across wheel 306. For example, to use floss delivery device 300, a user may optionally thread a tip of a piece of floss 309 through guide opening 305 (from right to left in the view of FIG. 3 ) before inserting the tip of the piece of floss 309 into floss-receiving port 310, and then place the tip of the piece of floss 309 on top of wheel 306 and secure floss 309 in place relative to wheel 306 with a thumb or fingers of the hand (not shown). In another example, a user may choose not to use floss threading guide 304 (if available). In another example, a user may choose to first secure a portion of floss 309 in place on wheel 306 before inserting the tip of floss 309 through floss-receiving port 310.

[0033] In one or more embodiments, the wheel 306 includes a channel 308 defined, for example, by a depression, groove, or notch in the surface of the wheel 306. For example, as shown in FIG 3, the channel 308 may be defined by one or more notches substantially in the center of one or more ridges 307 of the wheel 306 that a user may use to rotate the wheel 306.

[0034] In some embodiments, one or more of the ridges 307 may have a concave shape to assist the user in holding the floss 309 in place on the top of the wheel 306 as the floss 309 is advanced. According to some embodiments, the top surface of the wheel 306 and / or each ridge 307 may be slightly concave and may have a groove in the center to assist in keeping the threaded portion of the threader floss precisely positioned (e.g., centered on the wheel ridge 307) for maximum ease of manipulation when advancing the threader between the thumb of the hand and the wheel 307. In one or more embodiments, the wheel 306 does not include any channels, does not include any concave features, and / or does not include any ridges.

[0035] Continuing with the example of setting up a piece of floss 309 for delivery, a user may use the thumb or fingers of their hand (not shown) to press against the floss 309 placed atop wheel 306 and rotate wheel 306 (e.g., by moving the fingers from right to left in the view of FIG. 3) toward floss-receiving port 310. In this way, the user, assisted by the rotation of wheel 306, may effectively push or otherwise advance the floss 309 further into floss-receiving port 310, and thus further into end 314, toward a delivery opening (not shown, see e.g., delivery opening 116 in FIG. 1).

[0036] According to some embodiments, floss-receiving ports (e.g., floss-receiving port 110, floss-receiving port 112, and / or floss-receiving port 310) may be configured with a dimensional height, defined as the distance between the wheel and the inner surface of the outermost structure of the floss delivery device, that is large enough to advantageously provide an easier target for a user attempting to insert floss into the floss-receiving port. For example, exemplary floss delivery device 100, as shown in Figures 1 and 2, has a curved or "flared" shape proximate floss-receiving ports 110 and 112 and wheel 106 to provide a wider gap for inserting floss. An example of an easy-to-use floss-receiving port resulting from this curved shape is seen in Figure 8, which shows the relative height of floss-receiving port 110.

[0037] Thus, some embodiments of the floss delivery device provide curved portions adjacent to and defining a corresponding floss receiving port. In one or more embodiments, the floss delivery device includes at least one flared portion, each flared portion defining a corresponding floss receiving port. According to some embodiments, the widest lateral portion of the floss delivery device defines the depth of at least one floss receiving port, and in some embodiments, the widest lateral portion is wider than the wheels of the floss delivery device.

[0038] FIG. 4 shows an alternative (top) view of the exemplary floss delivery device 100 of FIG. 1, FIG. 5 shows an alternative (bottom) view of the exemplary floss delivery device 100 of FIG. 1, and FIG. 6 shows an alternative (side) view of the exemplary floss delivery device 100 of FIG. 1.

[0039] Figure 7 shows a front view of the exemplary floss delivery device 100 of Figure 1, particularly showing the hole or delivery opening 116 at the end of end 114 through which floss may be delivered according to certain embodiments described in this disclosure. Figure 8 shows a rear view of the exemplary floss delivery device 100 of Figure 1, showing the dual access to wheel 106, first floss receiving port 110, and second floss receiving port 112.

[0040] According to some embodiments described in the present disclosure, the delivery device provides a hybrid feeding action for feeding floss. To advance threader floss (or other type of floss) into the intended area of ​​the mouth, the thumb of the user's hand preferably directly engages the threader, such as by pressing the threader against the wheel with the thumb. In this manner, the threader may be advanced through a front end or feeder snout, not automatically by the device, and not only by the thumb of the user's hand, but by the threader being caught between the hybrid action of the ball of the user's thumb and the wheel. This combined action capability advantageously allows the user much greater control over the threader and its application to a desired location. Such control achieved by the hybrid action is significantly greater than, for example, when the threader is fed to opposing gears or rollers, or when fed by a single gear or roller against a stationary surface.

[0041] 9A shows a diagram of an example of use of a floss delivery device to apply floss into a user's mouth, according to one or more embodiments. According to the example of use shown in FIG. 9A, after setting up floss 907a in floss delivery device 900 by threading it through floss threading guide 904a (e.g., as described with respect to FIG. 3), a user holding floss delivery device 900 in hand 901 may use thumb 903 (or other fingers) to press floss 907a against wheel 906 while holding handle 902. The user may then advance floss 907a further into receiving port 910 by rotating or flicking wheel 906 and floss 907a toward receiving port 910, thereby pushing floss 907a into end 914 and out of delivery opening 916. In this manner, the user can apply tip 920a of floss 907a at and within a desired interproximal location 918 (e.g., between two teeth in the user's mouth 930). The user may then grasp tip 920a (e.g., using another hand (not shown)) and begin cleaning the interproximal location 918 with floss 907a.

[0042] In the use depicted in the diagram of FIG. 9A, the user utilizes the wheel 906, floss threading guide 904a, and first floss receiving port 910 of the exemplary floss delivery device 900 to apply floss 907a to the top of the user's mouth 930. In another use, as shown in the diagram of FIG. 9B, the user may choose to hold the floss delivery device 900 differently to reach a different interproximal location 919. As described herein, according to some embodiments, the floss delivery device 900 may provide dual access to the wheel 906 and / or provide dual floss receiving ports, allowing the user to choose how the user wants to hold the device 900. As shown in FIG. 9B, the user may choose to hold the floss delivery device 900 rotated and / or inverted relative to the use depicted in FIG. 9A, to access the wheel 906 using a different opening, and to advance the floss through the second floss receiving port 912.

[0043] Specifically, in the example use shown in FIG. 9B, the user fed floss 907b through different floss threading guides 904b, over different sides of wheel 906 (accessed using different openings in device 900), and into different floss receiving ports 912. The user can advance tip 920b of floss 907b through end 914, out delivery opening 916, and into interproximal location 919 by advancing floss 907b using wheel 906 in a manner similar to the process described with respect to FIG. 9B. The user may use another hand 932 to grasp tip 920b and remove floss 907b completely from device 900 and / or begin flossing at interproximal location 919.

[0044] FIG. 10 illustrates an exploded view of an exemplary floss delivery device, such as the exemplary floss delivery device 100 of FIG. 1, according to some embodiments. As shown in FIG. 10, a floss delivery device may be formed of substantially similar parts. In FIG. 10, the exemplary floss delivery device includes two parts 101a, 101b that are substantially similar to each other. One half may be configured with fastening means configured to connect with corresponding fastening means on the other half. In the example of FIG. 10, posts on the floss guide portion of part 101b may be configured to fit into corresponding holes (not shown) in part 101b to secure parts 101a and 101b to each other.

[0045] As shown in Fig. 10, the wheel 106 may be rotatably fixed between the two parts 101a, 101b by fitting an axle portion into a corresponding axle slot of each part 101, 101b. For example, as shown in Fig. 10, a lower axle portion of the wheel 106 (not shown in Fig. 10) fits into a corresponding axle slot 109 on the part 101b, and similarly, a lower axle slot (not shown) of the part 101a can accommodate the axle portion 107. Preferably, the parts 101a, 101b are configured to be fixable with the wheel 106 between the parts 101a, 101b such that the wheel 106 can rotate freely (e.g., when pressure is applied by a user's thumb). 10 depicts the shaft portion (e.g., shaft portion 107) as being fully contained within the device formed by parts 101a, 101b, according to some alternative embodiments, the shaft portion may be configured to extend partially or completely through the exterior of a part (e.g., part 101b). In one embodiment, the shaft slot may extend completely through to the exterior of the part.

[0046] According to some embodiments, a floss delivery device is provided that has a dual port design that allows the user to select a wide range of insertion angles (e.g., 180 degrees) while allowing the user to keep the thumb comfortably and ergonomically correct facing toward the user. Regardless of which port (e.g., top or bottom port) the user selects to feed floss into the device, the user can statically maintain the thumb on gear motion. The range of freedom includes the feeder snout facing away from or towards the user's intended mouth area.

[0047] According to some embodiments, a method of using a floss delivery device to apply floss to clean teeth may include grasping a tip (e.g., a rigid tip of a threader floss) of a piece of threader floss (or other type of floss) between the thumb and index finger of a hand and guiding the end into one of one or more floss receiving ports of the device, positioning a delivery opening (also called a feeder snout or feeder tube) of the device at an interdental or other interproximal location of the mouth where flossing is desired (e.g., to clean braces and / or other types of retainers), advancing the end of the threader floss by pressing the threader floss against the wheel with the thumb of a hand to rotate the wheel, and grasping the tip between the thumb and index finger of a hand once the end of the threader floss has passed the desired interproximal location. The user may begin flossing, for example, by setting the device aside, grasping the other end of the threader floss with the thumb and index finger of the other hand, and flossing the interproximal location with the inserted threader floss in a typical manner.

[0056] The terms "a," "an," and "the" mean "one or more," unless otherwise specified.

[0057] The term "plurality" means "two or more" unless otherwise specified.

[0058] The term "herein" means "in the present disclosure, including anything that may be incorporated by reference," unless otherwise specified.

[0059] The phrase "at least one of," when such phrase modifies a plurality of things (such as an enumerated list of things), means any combination of one or more of those things, unless otherwise stated. For example, the phrase at least one of widgets, cars, and wheels means any of (i) widgets, (ii) cars, (iii) wheels, (iv) widgets and cars, (v) widgets and wheels, (vi) cars and wheels, or (vii) widgets, cars, and wheels.

[0060] If a limitation of a first claim covers one of the features as well as two or more of the features (e.g., a limitation such as "at least one widget" covers one widget as well as two or more widgets), and in a second claim that depends from the first claim, the second claim uses the definite article "the" to refer to the limitation (e.g., "the widget"), this does not mean that the first claim covers only one of the features, nor does it mean that the second claim covers only one of the features (e.g., "the widget" can cover both one widget and two or more widgets).

[0061] Each process (whether referred to as a method, algorithm, or otherwise) inherently includes one or more steps, and thus all references to a "step" or "steps" of a process have inherent antecedent in the mere recitation of the term "process" or similar term. Thus, any reference in a claim to a "step" or "steps" of a process has sufficient antecedent.

[0062] When an ordinal number (such as "first," "second," "third," etc.) is used as an adjective before a term, the ordinal number is used (unless explicitly specified otherwise) merely to indicate a particular feature, e.g., to distinguish that particular feature from another feature described by the same or a similar term. For example, a "first widget" may be so named merely to distinguish it from, e.g., a "second widget." Thus, the mere use of the ordinal numbers "first" and "second" before the term "widget" does not indicate any other relationship between the two widgets, nor does it likewise indicate any other characteristic of either or both widgets. For example, the mere use of the ordinal numbers "first" and "second" before the term "widget" does not (1) indicate that either widget comes in an order or position before or after any other, (2) indicate that either widget occurs or acts before or after any other in time, and (3) indicate that either widget is ranked above or below any other, such as in importance or quality. Additionally, the mere use of an ordinal number does not define a numerical limit on the feature identified by the ordinal number. For example, the mere use of the ordinal numbers "first" and "second" before the term "widget" does not indicate that there must be two or fewer widgets.

[0063] As used in this disclosure, "user" may generally refer to any individual and / or entity that operates a user device.

[0064] A description of an embodiment having several components or features does not imply that any particular one of such components and / or features is required. In contrast, a variety of optional components are described to illustrate the wide variety of possible embodiments of the invention. Unless expressly specified otherwise, a component and / or feature is not essential or required.

[0065] Furthermore, although process steps, algorithms, and the like may be described or depicted in a sequential order, such processes may be configured to function in one or more different orders. In other words, any sequence or order of steps that may be explicitly described or depicted does not necessarily indicate a requirement that the steps be performed in that order. Steps of processes described in this disclosure may be performed in any order that is practical. Furthermore, some steps may be performed simultaneously, even though they are described or implied as occurring non-concurrently (e.g., because one step is described after the other). Furthermore, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications, does not imply that the illustrated process or any of its steps are required for the invention, and does not imply that the illustrated process is preferred.

[0066] While the present invention has been illustrated by the description of various embodiments, and these embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such details. Further advantages and modifications will be readily apparent to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and methods, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the general inventive concept.

[0067] This disclosure provides one of ordinary skill in the art with an enabling description of several embodiments and / or inventions. Some of these embodiments and / or inventions may not be claimed in this application, but may nonetheless be claimed in one or more continuing applications claiming benefit of priority to this application. Applicant reserves the right to file additional applications to pursue patents on subject matter disclosed and enabled but not claimed in this application.
