BACKGROUND OF THE INVENTION
Field of the Invention
This invention is directed to an oral hygiene device structured to cleanse and/or refresh the interior of the oral cavity. A head portion of the device includes a plurality of outwardly extending, flexible cleansing members having a releasable, hygienic composition disposed thereon. A handle is attached to the head for placement and manipulation thereof within the user's mouth in a manner which provides a predetermined cleansing action, wherein the handle is configured to be visually distinguishable from a conventional toothbrush and thereby be unobtrusive, when used in public.
Description of the Related Art
Good dental and oral hygiene is dependent on frequent and/or regular cleansing of the teeth, gums, etc. In accomplishing this task, an individual may use a conventionally structured toothbrush comprising an elongated, substantially rigid handle. A collection of fiber-like bristles are connected to a head having a substantially flat supporting base which facilitates the outward extension of the bristles in a substantially common direction. Such standard toothbrush structures have long been recognized as being operationally effective, at least to those individuals preferring to use a non-powered brushing instrument.
While various different sizes, shapes, etc. of known toothbrush structures are available to the public, a majority of these typically have common structural components. In addition, it is also recognized that the structural features of conventional toothbrushes promote a scrubbing or cleansing action comprising a reciprocal, back and forth or up and down motion, on the teeth, gums, etc. Also, a hygienic composition is added during the manipulation of the head and bristles in order to remove films, residues, plaque, etc. that can and do frequently build up on the teeth and gums in a relatively short period of time.
Although conventional toothbrushes of the type set forth above are prolific, in some instances they are less than desirable or acceptable. By way of example, some individuals intent on maintaining dental hygiene prefer to clean their teeth numerous times throughout a working day. However, in such situations use of a conventionally structured and designed toothbrush in a public area or in the presence of others is generally not considered to be acceptable. In addition to detracting from an individual's appearance while performing a cleansing procedure, the conventional toothbrush structure is not structurally adapted to be carried on the person of an individual on a frequent, day to day basis.
To overcome such problems and disadvantages, a variety of modified toothbrush structures and/or dental hygiene kits have been developed which attempt to facilitate more frequent cleaning of the teeth including, but not limited to, in environments where oral hygiene is not normally conducted. By way of example, collapsible or foldable toothbrush structures are known, wherein various portions thereof may interact to reduce the dimension and/or configuration thereof in order to facilitate it being more conveniently carried. However, such collapsible structures may be overly complex and less than totally reliable in terms of performing a continuously repeated, scrubbing or cleansing action on an individual's teeth. Similar disadvantages are associated with hygiene kits which may not include a conventional toothbrush instrument. Instead, known dental hygiene kits include various types of dental wipes or “finger gloves” dimensioned, configured and structured to perform at least a minimal cleansing action on the teeth and gums of an individual.
However, in both situations a separate supply of cleansing agent such as toothpaste, tooth powder or like dentifrice must be separately provided and independently carried. In order to overcome this type of disadvantage, some known, portable and/or disposable toothbrush structures incorporate a built in supply of dentifrice within the body of the cleansing instrument. As such, the integrated supply of dentifrice is supplied to the head and bristle area of the toothbrush by a pumping action or other predetermined manipulation of the device by the individual.
Based on the above, there is a long recognized need in the area of oral hygiene for an instrument which is totally self-contained, uniquely structured, and does not require a supplemental supply of cleansing agent to affect its use. Such a preferred and proposed device or instrument should preferably be capable of being used in public in a non-obtrusive manner even when other individuals are present. Moreover, the structural features of such a preferred and proposed oral hygiene device should facilitate its single use or limited use and its disposal thereafter. As a result, a preferred oral hygiene device could be carried on the person of an individual and be used in most public areas to perform a thorough and efficient cleaning of the teeth, gums and other intended portions of the oral cavity.
SUMMARY OF THE INVENTION
The present invention is directed to an oral hygiene device designed for use by an individual in a non-obtrusive manner, such as when the individual is out in public. As such, the structural features of the oral hygiene device are such as to not resemble a toothbrush or other conventional structures used to facilitate cleaning of the mouth, teeth, etc. Therefore, an individual could openly use the device in any of a number of public locations and in the presence of other individuals due at least in part to a handle portion of the device. More specifically, the handle may be dimensioned and configured to resemble a handle or “stick” of the type normally associated with “lollipop”, “sucker” or other edible confectionary product.
In addition, the oral hygiene device of the present invention comprises a head having a plurality of cleansing members secured thereto and extending outwardly therefrom. Moreover, both the outer surface configuration of the head as well as a predetermined array in which the plurality of cleansing members are disposed facilitate the efficient and sometimes concurrent cleansing of the various portions of the interior of the mouth including the teeth, gums, tongue, etc. To facilitate such cleaning and provide a unique cleaning action to the head the handle is secured to the head and extends outwardly therefrom. The handle, in addition to having the above described configuration, is also of sufficient length to facilitate a combined and/or independent rotary and/or reciprocal motion thereof to accomplish confronting engagement of the plurality of cleansing members with the teeth, gums, tongue, etc. In addition, at least one embodiment of the handle includes a portion thereof, such as a free, distal end, being at least partially dimensioned and configured to facilitate its use as a “toothpick”.
Additional operative features of one or more of the preferred embodiments of the present invention comprise the inclusion of a releasable hygienic composition disposed on or impregnated within at least some of the plurality of cleansing members and/or the outer surface portion of the head. Such a releasable, hygienic composition may comprise a breathe freshener, cleansing agent (toothpaste) or a combination thereof which accomplishes the hygienic goal of an individual. Therefore, an individual, while in a public area or location and in the presence of others, may serve to freshen his or her breathe and/or perform a cleaning action of the teeth, gums, etc. in a non-obvious manner. Such an unobtrusive use of the device is at least partially due to the fact that the handle significantly differs in appearance from that of a toothbrush and more closely resembles the structure of an edible, handle mounted product, as generally set forth above. As a result, it would appear that an individual would be eating or enjoying an edible confectionary product, which may be generally acceptable, rather than performing oral hygiene which is generally not done public.
More specific structural and operative features of the head of the device include an end portion which may at least partially define the outer end of the device. Moreover, the end portion of the head preferably includes a substantially hemispherical outer surface configuration. In addition, the head includes an elongated base extending between the end portion and the handle and at least partially including a curvilinear outer surface configuration. The predetermined array in which the plurality of cleansing members are disposed is intended to further facilitate the compound rotary and reciprocal cleansing action of the head once positioned in the mouth of a user. Therefore in at least one preferred embodiment, the plurality of cleansing members extend along substantially the entire hemispherical surface configuration of the end portion as well as that of the elongated, curvilinear outer surface configuration of the base portion.
The predetermined array of the plurality of cleansing members may also be accurately described as extending outwardly from the corresponding surface of the head in different directions. As a result, at least a majority of the plurality of cleansing members extend outwardly in different directions relative to one another. In such a preferred embodiment, the predetermined array of the plurality of cleansing members may also be defined by structuring and configuring the cleansing members into a plurality of transversely spaced apart rows, wherein each cleansing member of the same row or adjacent rows are disposed in spaced, segregated, non-engaging relation to one another. More specifically, each of the cleansing members may be formed of a flexible, soft, possibly resilient material, wherein each cleansing member is normally maintained in the spaced, non-engaging relation relative to others of the cleansing members until the head is disposed on the interior of the mouth of a user.
Therefore it is emphasized that the shape of the head, including that of the end portion and the base portion, as well as the configuration of the array assumed by the plurality of cleansing members, especially as operationally combined with the dimension and configuration of the handle do not represent mere design choices. Rather, these structural features are such as to facilitate the performance of the above noted compound cleaning action and the concurrent engagement of different areas of the teeth, gums, etc.
These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As represented in the accompanying Figures, the present invention is directed to an oral hygiene device generally indicated as 10. As such, the structural and operative features of the device 10 facilitate the accomplishment of oral hygiene, at least in terms of breath freshening and/or cleansing in a non-obvious, unobtrusive manner, thereby facilitating the use of the device 10 in a public location and in the presence of others.
Accordingly, the device 10 comprises a head generally indicated as 12 and a handle generally indicated as 14. As also represented, the handle 14 has an elongated configuration of sufficient length to facilitate positioning of the head 12 in the mouth of an individual and the selective, predetermined manipulation of the head and plurality of cleansing members 16. More specifically and as described in greater detail hereinafter, the head 12 and the plurality of cleansing members 16 may be selectively and concurrently moved in a compound or combined reciprocal and rotary cleansing motion by exerting a combined reciprocal and twirling motion on the handle, once the head is in the user's mouth. As also represented, the handle 10 includes a substantially cylindrical configuration extending continuously along its length. Such a cylindrical configuration is more specifically defined by a circular or other curved exterior surface configuration 14′ as clearly represented in FIG. 6. Therefore, the handle 14 is specifically dimensioned and configured to be visually distinguishable from the appearance of a toothbrush or other conventional hygiene product and facilitate the “twirling” motion thereof by the user. As indicated, during use the head 12 is placed within the user's mouth and moved or otherwise manipulated to accomplish the hygienic procedure, as set forth above. However, at least a portion of the length of the handle 14 will protrude from the user's mouth and may be engaged by the hand of the user. Therefore, the appearance of the oral hygiene device 10 and in particular, the handle 14, will resemble that of a handle or “stick” used to support a conventional, edible confectionary product, such as a lollipop. As a result, an individual can accomplish the hygienic procedure in public and in the presence of others in a non-obtrusive manner.
Other structural and operative features of the oral hygiene device 10 include the plurality of cleansing members 16 connected to and extending outwardly from the surface of the head 12. In at least one preferred embodiment, the plurality of cleansing members 16 are made of a flexible, soft, possibly resilient material having sufficient inherent bias to normally assume the orientation appearing throughout the Figures. The plurality of cleansing members 16 are connected to the head 12 and/or integrally formed in association with the outer surface thereof in a “predetermined array”. Such predetermined array is more specifically defined by a plurality of cleansing member 16 disposed in spaced, segregated, non-engaging relation to one another prior to entering the user's mouth and confronting interior portions thereof to perform a cleansing or other hygienic procedure. The predetermined array of the plurality of cleansing members 16 may be more specifically defined by a plurality of groupings 18 of the plurality of cleansing members 16. Each grouping 18 defines a row of the plurality of cleansing members 16 extending outwardly from the head 12 in a direction which differs from the plurality of cleansing members 16 defining others of the plurality of rows 18. Accordingly, while a majority of the cleansing members 16 extend outwardly from the head 12 in different directions, many of the plurality of cleansing members 16 defining a common row 18 extend outwardly from the surface of the end 20 of the head 12 in a different direction and outwardly from the surface of the base 22 in substantially common directions, as represented in FIGS. 1-8
As a result, the predetermined array of the plurality of cleansing members 16 as generally defined above, facilitates the efficient and effective performance of the hygienic procedure once the head 12 is placed in the mouth of a user. The hygienic procedure may include brushing, scrubbing or other confronting engagement with interior portions of the mouth including the teeth, tongue, gums, etc. Further the lateral spacing between the rows 18 and the spacing between the cleansing members 16 of the same row 18 facilitates concurrent engagement with upper and lower teeth and the positioning of the cleansing members 16 between the teeth. In addition, the predetermined array in which the plurality of cleansing members 16 is collectively disposed may be further defined by their placement continuously along the outer surface of substantially the entirety of the head 12 or at least a majority thereof. More specifically, the head 12 is configured and overall structured to include an end portion 20, and a base portion 22 integrally or contiguously disposed relative to one another, as at 24.
Moreover, the end portion 20 includes a substantially hemispherical outer surface configuration. In cooperation therewith, the base portion 22 includes a substantially elongated curved or curvilinear outer surface configuration as the base portion 22 extends between and/or intermediate of the handle 14 and the end portion 20. As a result, the aforementioned predetermined array of cleansing members 16 may be further defined by each of the plurality of cleansing member 16 collectively disposed in their respective rows 18, wherein each row is of sufficient length to extend along substantially the entire hemispherical or curvilinear surface of the end portion 20 and base portion 22 respectively. Therefore it is emphasized that the aforementioned predetermined array of the plurality of cleansing members 16, as well as the specifically defined outer curved configuration of the end portion 20 and the base portion 22, are not mere design choices but are structured to facilitate performance of the hygienic procedure including the ability to accomplish a combined or compound motion and/or cleaning action when such is desired.
Additional features associated with one or more preferred embodiments of the present invention are the inclusion of one or more hygienic compositions disposed on or embedded or impregnated within at least some of a plurality of cleansing members 16 and/or the outer surface of the end portion 20 and/or base 22. Moreover, the one or more included hygienic compositions are formulated to be releasable into the mouth of the user when moistened, such as when engaging the saliva of the user. As a result, the plurality of cleansing members and/or the outer surface of the head 12 can include the hygienic composition in the form of a breath freshener, cleansing agent (toothpaste), and be in the form of a gel, paste, solution, powder or other appropriate form.
In one or more preferred embodiments of the present invention, as shown in FIG. 12, the hygienic composition may instead or also take the form of a cleansing element 40, a rigid or semi-rigid structure disposed on the proximate end of the handle 14. The cleansing element 40 can range in consistency from rigid, hard or solid to one that is soft, semi-rigid, pliable and/or gum-like. The cleansing element 40 is transferable, meaning it is chewable and/or formulated to dissolve when moistened, such as when engaging the saliva of the user. In any case, the cleansing element 40 releases a hygienic composition, such as xylitol and/or a breath freshener. The cleansing element 40 may include an apertured construction, such as a disc or cylinder with a hole through the middle, which fits over the proximate end of the handle 14 as shown in FIG. 12. The proximate end is that end of the invention disposed so as to allow concurrent insertion with the head 12 into the mouth of the user. The cleansing element 40 in the depicted embodiment of FIG. 12 is frictionally mounted so as to be fixed but still removable, but the cleansing element 40 may instead be mounted by any other suitably adhesive or fixing alternative.
With primary reference to FIGS. 9-11, yet another preferred embodiment of the present invention includes the handle 14 having the cylindrically formed outer surface 14′ extending along at least a majority thereof. However at least a portion of the handle 14, such as the distal end or tip is dimensioned, configured and structured to form a “toothpick” like implement generally indicated as 26. The pick structure 26 may be integrally, fixedly or removably secured to the corresponding end 14′′ of the handle 14. As such, when the pick structure 26 is removably attached to the end 14′′ it can be removed and replaced before or after use thereby further facilitating the appearance of the handle 14 as the handle or stick associated with an edible product.
In more specific terms, the pick structure 26 includes a substantially convergent configuration extending from the junction with the end 14′′ to the outer most extremity thereof as at 26′. As a result, the transverse or circumferential dimension of the pick structure 26 at or adjacent the extremity 26′ will be sufficient to facilitate the use of the pick structure 26 in a manner similar to a conventional toothpick. However, the extremity 26′ will be at least partially rounded to avoid an excessively sharp point thereat in order to avoid harm or damage to the interior of the mouth of the user.
Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
Now that the invention has been described,
