FIELD OF THE INVENTION The present invention generally relates to the field of oral hygiene for humans and animals. More specifically, the present invention relates to a device and method of use of same for facilitating the cleansing of the areas of the mouth without damaging tooth enamel and creating irritation to the gum or other portions of the mouth area.
BACKGROUND OF THE INVENTION Oral hygiene is the practice of keeping the oral cavity clean to prevent dental concerns and limit the presence of bacteria in the mouth region resulting in bad breath. The use of oral care implements, such as toothbrushes, soft tissue cleaner devices, and combination devices of similar nature, is highly recommended as severe gum disease results in a substantial percentage of adult tooth loss. In addition, tooth decay is the most common global disease resulting from the generation of cavities inside pits and fissures on chewing surfaces where brushing cannot reach trapped and remaining food and saliva or fluoride have no access to neutralize acid and re-mineralize de-mineralized teeth.
Proper oral hygiene is essential for preventing calculus or tartar build-up, a form of hardened dental plaque (a sticky film exhibiting bacteria that forms on the teeth and gums capable of releasing acid that attacks tooth enamel and resulting tooth decay). Plaque accumulation causes the gingiva to become irritated and inflamed, resulting in the eventual loss of the connective tissue fibers that attach the gums to the teeth and bone that surrounds the tooth (i.e., periodontitis). The most common form of proper oral hygiene is the frequent and regular brushing of the mouth region and teeth with a toothbrush and the use of dental floss to prevent accumulation of plaque on the teeth. Supplemental oral hygiene methods and related implements such as tongue cleaning devices are utilized to remove the coating of bacteria commonly capable of causing bad breath, decaying food particles, fungi, and dead cells from the dorsal area of tongue. In addition, the use of mouthwash or other dental oral hygiene rinses may aid in the removal of bacteria.
Historically, a variety of oral hygiene measures have been used for teeth cleaning. For example, analysis of the activities of various worldwide cultures has resulted in evidence reflecting the use of chew sticks, tree twigs, bird feathers, animal bones, and porcupine quills as common devices for tooth cleaning and maintenance.
Today, the most common device utilized for proper oral hygiene is the toothbrush. In general, a toothbrush is an oral hygiene instrument used to clean the teeth and gums that consists of a head of clustered bristles fixed in a position on a handle, which facilitates the cleansing of areas of the mouth. Common toothpastes, a paste or gel dentifrice, are used in the conjunction with the toothbrush to improve the effectiveness of the movement of the toothbrush. Toothpaste acts as an abrasive that aids in removing the dental plaque and food from the teeth, assists in the elimination and/or masking of halitosis, and delivers active ingredients such as fluoride or xylitol to help prevent tooth and gum disease.
Toothbrushes are presently manufactured in numerous forms with a myriad of reported purposes and objectives designed to improve the effectiveness of the toothbrush. In particular, toothbrushes are available with different bristle textures, bristle types (including synthetic and animal hair bristles), and handle and brush head sizes and forms.
As the need for proper hygiene is so pervasive, the United States Patent and Trademark Office is replete with examples of attempts to satisfy this need. To that end, the United States Patent and Trademark Office has examined patent applications purporting solutions for dental care for over one hundred years including a patent issued to H. N. Wadsworth in 1857 (U.S. Pat. No. 18,653) for a device manufactured of a bone handle exhibiting bored holes for the placement of animal hair therewithin, which is likely the earliest issued patent in the field.
More advanced issued United States Patents for common oral care implements include the development of devices, methods, and means to eliminate mouth-borne bacteria. Conventional toothbrushes typically exhibit a head of a parallelogram shape containing fixed nylon bristle tufts. In certain advanced devices, additional cleansing structures may be employed for such desired purposes as massaging gums, cleaning the soft tissue of the tongue, or other like purposes.
A first example of an improved tooth-cleaning device is embodied in Hyman U.S. Pat. No. 3,754,295 which issued on Aug. 28, 1973. The purpose of the disclosed invention, entitled “Two-Headed Brush,” was to provide “a two-headed brush having a general utility and, more particularly, to a two-headed toothbrush.”
The Hyman invention was designed as a “two-headed brush comprising an elongated handle having a tapered structure, bristles secured to a relatively broad head portion of said handle and extending laterally there from, a second group of bristles attached to a narrow end portion of said.” The unique sizes (i.e., a narrow and a broad head) and positioning of the bristles on the opposing ends of the elongated handle were designed to “effect removal of plaque at the gum line without causing serious discomfort and irritation to the gum.”
While the application of Hyman was likely an important disclosure at the time of its issuance, such a primitive disclosure reveals many disadvantages. Importantly, the design of the toothbrush heads have limited ability to retain dentifrice, mouthwashes, or other oral hygiene pastes and gels for the application on a tooth or soft tissue regions of the mouth. Therefore, the need for a solution that allows for the portability of a brushing device exhibiting a plurality of brushing heads and containing oral hygiene dentifrice or other similar oral hygiene materials in a single device continues to exist.
In a second example, a disposable and reusable toothbrush with toothpaste disposed in the handle of the device is disclosed in Lafortune U.S. Pat. No. 5,584,593. Lafortune acknowledges that certain contemporaneous art in the field exhibits improvements in the art, however, readily acknowledges certain shortcomings in the field. Specifically, Lafortune claims that while certain toothbrushes in the art employ a brush and dentifrice disposed therein thereby eliminating the need for both a toothbrush and a toothpaste tube such toothbrushes have been intended for long-time use and as a result “complex and expensive solutions” to the refilling of the handles with toothpaste have been implemented. “Also, in the prior toothbrushes, valves have been used which prevent the expulsion and waste of toothpaste and the contact of the toothpaste with air which would result in caking” and “[s]uch valves add significantly to the cost of the toothbrushes.”
Thus, Lafortune discloses a toothbrush having a front and back surface and a handle, neck and head. The disclosed handle contains a hollow area containing sufficient toothpaste for one to three brushings. The hollow area is covered with a compressible plastic pad which allows for the forcing of the toothpaste from the hollow area. The neck of the toothbrush contains a duct which leads from the hollow area of the handle to openings which are in the head of the toothbrush. According to the disclosure, a series of openings evenly dispersed throughout the bristle tufts in the head of the toothbrush allow for the user to force toothpaste through the openings to the bristle tufts.
According to the disclosure, the aforementioned design provides “an inexpensive combination of toothbrush and toothpaste which is effective to provide toothpaste from the handle to the bristles of the toothbrush” for one to three brushings. In addition, Lafortune is designed to “provide an inexpensive method for preventing the expulsion of toothpaste from the handle and the concurrent wasting and caking of toothpaste.”
While the Lafortune disclosure is clearly an improvement over the existing art, it is limited to its short-term use. Further, Lafortune is only useful for the application of toothpaste and does not employ a means to utilize additional oral hygiene products such as mouthwash or the like.
A further improvement in the prior art, Moskovich U.S. Pat. No. 5,628,082 entitled “Toothbrush with Improved Efficacy,” is directed to a brush “with a secure grip, a more effective bristle arrangement, and a specially shaped head . . . which is highly effective for the removal of plaque from teeth with manual brushing.” In discussing the background of the art at the time of the disclosure, Moskovich acknowledges certain shortcomings in the prior art. Moskovich readily acknowledges that it is the objective in the field of the art to (1) “provide effective surface area cleaning, including the top of the crown of the tooth and the frontal planar portions,” (2) “provide cleaning at the gumline, where debris often accumulates out of the reach of normal tongue cleaning action,” (3) “provide effective cleaning between teeth,” (4) “reach the most confined regions of the oral cavity easily,” (5) provide a device “capable of directing force at teeth and surfaces individually, while simultaneously allowing brushing of larger surface areas,” (6) provide a device that is “comfortable and convenient,” and (7) provide a device that “effectively removes plaque.” While the design employed by the Moskovich disclosure arguably accomplishes the aforementioned objectives, the disclosure fails to provide a singular device for the employment of a brushing mechanism and release and containment of toothpastes and other oral hygiene solutions.
An additional improvement in the related field of the present invention, includes the disclosure of Durana International Patent Application Number PCT/SK99/00006 entitled “Toothbrush.” Durana discloses an improved toothbrush containing a “polishing block” positioned in close proximity to the bristles of the toothbrush and in at least one embodiment, the polishing block further comprising an antibacterial substance or manufactured from a non-harmful, edible, elastic, and non-soluble material containing abrasive particles for tooth polishing. The Durana disclosure declares that the “main advantages of the toothbrush according to the [Durana invention] include the improved ability of the perfect mouth cleaning [and] a simultaneously better polishing of tooth enamel. Another possibility is the antibacterial effect even without tooth paste.” While the insertion of a “polishing block” is clearly the novelty of the Durana disclosure, clearly such use of a soluble “polishing block” can not be replenished once the block is depleted after one or more periods of use.
Frazell U.S. Pat. No. 5,915,868 entitled “Portable Toothbrush with Dentifrice” depicts a further improvement in the existing art. Specifically, Frazell provides ergonomic embodiments of a disposable toothbrush having self-contained dentifrice package and a soft, flexible plastic head for breaking the dentifrice package and sharp, hollow tubes or needles for distributing the dentifrice to the bristles. The Frazell invention is described as an improvement over related art in its “innovative mechanical design, in its ergonomic facility in both gripping the handle and moving the soft, rounded head through the mouth, and in its outward appearance.” Further, the invention is argued to exhibit “important mechanical innovations” as the “head behind the bristles is constructed of soft, flex-memory plastic which can be compressed to force the packet within it against puncture means to release the dentifrice.”
While clearly an improvement over the existing art, Frazell fails to explore and implement a system comprising a dual-head design and means for providing a single compact unit for the dispersion of multiple oral hygiene solutions.
Andersen U.S. Pat. No. 6,524,023 provides a further improvement in the existing art. Anderson discloses a first embodiment of a compact disposable toothbrush kit including a toothpaste dispensing device for dispensing a disposable toothbrush and a toothpaste stick which attaches to the handle using an edible adhesive. In a second embodiment, Andersen discloses a disposable toothbrush kit including a toothpaste dispensing device for dispensing a disposable toothbrush and a plastic toothpaste-containing vial, adhesively attached to the toothbrush. Andersen claims that the device exhibits several advantages over the existing art as “it eliminates multiple users of the common tube of toothpaste, providing separate individual doses of toothpaste to each person” and it aids in the decrease of “the spread of disease between family members and toothpaste users.” While the Andersen disclosure is likely an improvement over the then-existing art as it potentially exhibits its intended objective, the Andersen disclosure fails to provide a system comprising a dual-head design and means for providing a single unit for the dispersion of multiple oral hygiene solutions. Further, Andersen fails to provide a device capable of providing multiple layers of oral hygiene cleaning such as tongue cleansing or improved bristle placement.
Clark U.S. Pat. No. 6,769,828 discloses a plurality of embodiments of a chewable toothbrush. Specifically, Clark provides a chewable toothbrush including a pliable bristle anchor, bristles attached to the bristle anchor, and a handle attached to the bristle anchor. In one embodiment, the bristle anchor includes a cavity that holds a material such as toothpaste or mouthwash which is released from the cavity when the toothbrush is chewed by a user. The toothbrush disclosed by Clark may be a single-use disposable unit or as a multiple-use unit by reloading the dispensing portion. However, it will be readily apparent to one of ordinary skill in the art that Clark fails to disclose a dual-head design and means for providing a single unit for the dispersion of multiple oral hygiene solutions. Further, Clark fails to provide a device capable of providing multiple layers of oral hygiene cleaning such as tongue cleansing or improved bristle placement.
Turning yet to another disclosure in the related field of the art, Wong U.S. Patent Application No. 2005/0071939 discloses a “Dual Head Toothbrush.” The Wong U.S. patent application is directed to a toothbrush body including an integral head, a body, and a tail portion, wherein the head includes indents for receiving bristles and the tail portion, which is inclined relative to the body portion, includes an indent for receiving the base of an interdental brush. Clearly, the Wong disclosure includes more than one layer of oral hygiene cleaning (i.e., a toothbrush and an interdental brush designed to “clean areas of the mouth inaccessible or awkward to reach with the main brush”), however, Wong fails to provide a device capable of dispersing toothpaste or similar oral hygiene solutions.
U.S. Pat. No. 6,895,629 to Wenzler entitled “Double Sided Toothbrush” discloses a further development in the field of the relevant art. Wenzler is directed to an improved toothbrush employing a scrapper device opposite the toothbrush bristles. According to the disclosure, Wenzler is directed to a toothbrush having a handle and a head, wherein a plurality of relatively straight bristle fibers extend outward from one side of a bristle-supporting portion of the head to provide a looped coarse scrubbing surface. In addition, a plurality of looped fibers extend outward from another side of a looped fiber-supporting portion of the head, wherein an end of each looped fiber is fixably connected to the fiber supporting surface thereby providing a soft scrubbing loofah like surface. Further expanding on the disclosure, Wenzler claims that the straight bristles can be of varied length to aid in reaching crevices between the teeth and gums. In addition, the soft looped fibers can be used to scrub the roof of the mouth as well as the gum areas and the looped fiber supporting portion can be arcuate and can preferably extend beyond one hundred eighty to provide for a radial scrubbing surface aspect.
Wenzler includes more than one layer of oral hygiene cleaning (i.e., a toothbrush and a looped scrapping device for removal of bacteria from the roof portion of the mouth as well as the gum region). Like several of the earlier disclosures, Wenzler fails to provide a device capable of dispersing toothpaste or similar oral hygiene solutions in conjunction with the multiple oral cleansing devices.
Vazquez et al. International Patent Application No. PCT/US2008/054038 entitled “Toothbrush” further employs certain improvements to the common toothbrush. For example, Vazquez et al. discloses a plurality of toothbrush head configurations designed to “channel” user-applied toothpaste to the edges of the brush head. Vazquez et al. further discloses a head exhibiting a plurality of cleaning elements for enhanced cleaning of the teeth and the soft tissue of the oral cavity. Specifically, a first cleaning element comprises a plurality of bristles adapted to clean teeth while a second cleaning element is employed on the opposing side of the head to direct toothpaste previously applied by the user. The head further employs a location for the user-applied dentifrice so as to eliminate any user error allowing for the proper channeling of the dentifrice once in use. Numerous objectives of the Vazquez et al. invention are disclosed. For example, according to the specification, one of the features of Vazquez et al. is to provide a structure defining the channels including a plurality of members spaced from one another to define the recessed channels within gaps between the members and further including a plurality of protrusions forming a plurality of elongated ridges. Thus, the ridges and channels can have a variety of shapes, including serpentine shapes, arched shapes, and curved, elongated shapes. In addition, numerous cleaning elements are employed including a series of bristles adapted to clean teeth and a recessed reservoir defined and configured to receive user-applied dentifrice therein to assure proper placement of the dentifrice.
Each of these aforementioned features of Vazquez et al. are designed to improve the cleaning of the oral cavity. However, it is apparent from the disclosure that the present invention merely provides a recess for the placement of user-applied toothpaste from a common dispenser such as a tube rather than a portable device integrating the dentifrice therewithin. Further, Vazquez et al. fails to provide multiple cleaning implements for the application of more than one dentifrices such as toothpaste accompanied by a whitening gel or a mouthwash. Finally, Vazquez et al. fails to provide a means for integrating common dental floss or the like in a portable form in one integral unit.
A further prior art disclosure, entitled “Oral Care Implement” is directed to a portable, limited use toothbrush and an integral dispensing means for a dentifrice. In particular, Robinson et. al U.S. Patent Application Publication No. 2009/0320226A1, is directed to an oral care implement including a handle, a head mounted to one end of the handle that includes a first face having a plurality of tooth cleaning elements extending therefrom and a store of dentifrice retained at the head including a film matrix retained at the head containing at least one rapidly releasable agent. Robinson et al. further discloses the inclusion of a soft tissue cleaner included on a second face. It is further disclosed that the at least one rapidly releasable agent can be provided to the first and/or second faces during use from the film matrix wherein the at least one rapidly releasable agent can include, for example, a flavoring agent, a dentifrice, or a therapeutic agent. Finally, Robinson et al. is manufactured of a relatively small size and lightweight design so as to be readily portable for use away from the home.
Clearly, the benefit of the portability and integral design of Robinson et al. disclosure is an improvement over the known existing art. However, Robinson et al. still fails to provide multitude heads to allow for the application of discreet application of a plurality of dentifrice or related agents. Further, Robinson et al; fails to provide a plurality of cleaning implements to allow for tongue cleaning, roof cleaning, or other regions of the oral cavity, including hard to access regions. In addition, Robinson et al. fails to provide a means for the release of dental floss in one integral compact unit which is highly useful for personal at home use or use during travel.
In spite of the myriad of inventions and disclosures related to improved oral hygiene, it remains readily apparent that portable oral hygiene implements exhibit numerous shortcomings. Specifically, none of the aforementioned references provide for a hygienic and compact dual head toothbrush capable of adequately dispersing various oral hygiene solutions, pastes, and/or gels designed for single or multi-use which exhibits an ease of manufacture and limited complexity of use.
Therefore, the need still remains for a compact integral toothbrush exhibiting a myriad of cleaning elements for use with a plurality of dentifrice. Further, the need also remains for an inexpensive mechanism for single or multi-use which can be manufactured and refilled by the consumer at a consumer-appealing price.
SUMMARY OF THE INVENTION In view of the foregoing disadvantages inherent in the known and various oral care devices including those devices commonly developed for portable or single use, in accordance with a first preferred embodiment of the present invention, provided is a multi-use oral hygiene implement designed to improve oral care, especially oral care “on-the-go,” integrating a multitude of isolated dentifrices via a plurality of brushing heads and related cleaning elements. More specifically, the first preferred embodiment is designed to be utilized to reduce the presence of bacterium in the oral cavity of humans and animals by providing an integral unit employing dispensers for channeling and distributing toothpaste, toothpowder, therapeutic oral gels, mouthwashes, and the like as well as dental floss.
In short, in a primary embodiment, provided is a novel toothbrush with dentifrice feed system exhibiting ease of use and improved oral cleaning capability. The toothbrush, made of a common plastic material or the like, includes an ergonomic handle and grip mechanism for comfort of use and having a first head of ergonomic parallelogram shape positioned at a first end of the handle and a second head of ergonomic parallelogram shape positioned at a second end of the handle. The first head and second head employ a plurality of bristles of various shapes, lengths, strengths, and arrangements designed for particular cleaning aspects such as tooth cleaning, roof of mouth cleaning, tongue scrapping, plaque removal, gum massaging, etc. for maximum cleaning efficacy and various applications. Each head further including a plurality of grooves and channels to effectively distributing applied dentifrices during use of the oral care implement. Each head further including one or more reservoirs for maintaining a dentifrice pod or packet sealed in a soluble material such as a film. Such packets can contain any of a plurality of cleaning agents, including but not limited to toothpastes for improved tooth cleaning and mouthwash for killing germs in hard to reach places, freshening breath, loosening food caught between teeth, and fighting cavities.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A detailed illustrative embodiment of the present invention is disclosed herein. However, techniques, systems and operating structures in accordance with the present invention may be embodied in a wide variety of forms and modes, some of which may be quite different from those in the disclosed embodiment. Consequently, the specific structural and functional details disclosed herein are merely representative, yet in that regard, they are deemed to afford the best embodiment for purposes of disclosure and to provide a basis for the claims herein which define the scope of the present invention. The following presents a detailed description of a preferred embodiment (as well as some alternative embodiments) of the present invention.
Moreover, well known methods, procedures, and substances for both carrying out the objectives of the present invention and illustrating the preferred embodiment are incorporated herein but have not been described in detail as not to unnecessarily obscure novel aspects of the present invention.
Referring first to FIG. 1A, depicted is a cross-sectional side view in accordance with the preferred embodiment of the present invention prior to the placement of dentifrice capsule 118. Specifically, provided is an ergonomic oral hygiene implement 100 composed of an elongated handle 120 exhibiting an upper grip 102 and a lower grip 104 to aid in the control by the user of oral hygiene implement 100. Oral hygiene implement 100 is designed primarily for the cleaning of the teeth and soft tissue of the oral cavity (e.g., exterior regions of the tongue, cheeks, gums, lips, etc.), either human or animal. Oral hygiene implement is designed of appropriate dimensions to foster use by a user and allow a user to readily grip the implement and manipulate the implement so as to allow for substantial cleaning of the mouth region. In the present embodiment upper grip 102 and lower grip 104 exhibit protrusions, indentations, and smooth surfaces to allow for improved grip and traction for the engaged gripping digits of the user. Upper grip 102 and lower grip 104 are positioned to allow the user to securely utilize oral hygiene implement 100 in a bristle-up, bristle-down, or any position therebetween to provide a three hundred sixty degree range of motion for complete cleaning of the upper teeth, lower teeth, and soft tissue of the oral cavity without fear of slipping between the upper grip 102, lower grip 104, and elongated handle 120 with the user's gripping digits.
Oral hygiene implement 100 is preferably molded of a suitable thermoplastic material as a single integral unit by any common method known in the art such as injection molding or casting. The gripping elements (i.e., upper grip 102 and lower grip 104), are preferably manufactured of a common rubber material, rubber-like material, or other suitable deformable thermoplastic. These gripping elements may be adhered to elongated handle 120 with a suitable adhesive or, in the alternative, may be matted to the thermoplastic material via a common injection molding process. However, one of ordinary skill in the art will readily recognize that such complexity in manufacturing an oral hygiene implement utilizing unique materials may yield more expensive manufacturing costs and as a result may not be employed in alternate embodiments so as to reduce the cost of manufacture. For example, a singular injection molding process may be utilized wherein oral hygiene implement 100 is manufactured of a single material such as a thermoplastic, resin, polypropylene, rubber, wood, metal, or the like, including combinations thereof.
As depicted, oral hygiene implement 100 is comprised of an opposing dual-head construction with a first head 106 comprising first head reservoir 110 and first head bristles 108 positioned at a first end of elongated handle 120 and a second head 112 comprising second head reservoir 116 and second head bristles 114 positioned at opposing second end of elongated handle 120. While not depicted, elongated handle can be manufactured to allow for the angled placement of first head 106 and/or second head 112 with respect to the longitudinal axis of elongated handle 120 to aid in the improved control of oral hygiene implement 100, as widely recognized in the art.
With respect to the present embodiment, first head bristles 108 and second head bristles 114 are composed of tufts of nylon fibers extending outward and secured at fiber securing portions substantially straight and perpendicular to first head 106 and second head 112. As depicted, fibers of first head bristles 108 and second head bristles 114 are substantially straight and of even length, however, one of ordinary skill in the art will readily recognize that fibers of varying length, dimensions, material types (such as thermoplastic elastomer, linear low density polyethylene, ethylene vinyl acetate, or other similar resilient flexible material of combination thereof) may be employed while not departing from the spirit of the invention.
First head reservoir 110 and second head reservoir 116 are designed as a refillable dispenser allowing for the acceptance of dentifrice capsule 118, depicted as a gel-filled pod. However, it is well recognized that non-refillable, single use reservoirs may be employed. In the preferred embodiment, first head reservoir 110 and second head reservoir 116 are of sufficient dimensions to hold dentifrice pod 118 in place without the need for an attachment means, however, first head reservoir 110 and second head reservoir 116 can include prongs, dimples, ridges, or similar protrusions to allow a user to forcibly place the dentifrice therein allowing the attachment means to clasp and position the dentifrice for use. In addition, adhering substances such as water-soluble non-toxic glues to maintain the dentifrice in the reservoir.
Dentifrice capsule 118 is preferably depicted as encapsulated as it exhibits certain inherent advantages over the traditional method of toothpaste application wherein toothpaste is forcibly extruded from a tube onto toothbrush bristle. First, it is well known in the art that the use of toothpaste extruded from tubes results in uneven distribution. The uneven distribution results in the first area to be brushed receiving excess toothpaste and areas brushed later receiving minimal toothpaste application. The portions that receive excess toothpaste often experience unhealthy enamel wear while the portions that receive too little are not effectively cleaned.
The encapsulated style dentifrice capsule 118 is preferably manufactured in spherical shape stabilized in a non-toxic, biocompatible thin coating or shell designed to release the contents when ruptured by teeth or dissolved by saliva. For example, the coating may be manufactured of gelatin, choline, or other common conventional coatings known in the art. Dentifrice capsule 118 is designed to accomplish a variety of oral care applications such as therapeutic applications, alleviation of dry mouth, removal of putative bacteria, removal of sulfur-based compounds, reduction of dental plaque and resulting gingivitis, reduction of mouth odor, cleaning and whitening of teeth of the oral cavity, etc. Dentifrice capsule 118 can include any common dentifrice such as any desired quantity of toothpaste or other standard oral care dentifrice, including, but not limited to toothpowder, toothcare gel, toothcare liquids, aqueous oral care solution, etc. It is well known in the art that dentifrice can include a foaming agent or surfactant, binding agents, gelatin to help solidify the solution, stabilizers, odor-reducing agents, antibacterial agents, whitening agents, anti-sensitivity agents, anti-tarter agents, anti-plaque agents, plaque highlighting agents, anti-inflammatory agents, colorants, baking soda, traditional detergents as well as favored minerals such as fluoride. Dentifrice may also include sweetening agents, flavoring agents, nutritional agents, anti-stain agents, dissolving agents, or quick-release agents such as mint films or the like. It is well known in the art that numerous compounds accomplish the aforementioned oral care, including, but not limited to chlorhexidine, cetyl pyridinium chloride, ethyl lauroyl argening HCl, triclosan, zinc salts, hydrogen peroxide, urea peroxide, sodium percarbonate, KNO3, bachalin, polyphenols, triclosan, ethyl pyruvate, guanidinoethyl disulfide, vitamins, minerals, amino acids, folic acid, polyvinylphosphoric acid, or combinations thereof.
FIG. 1B depicts a cross-sectional side view in accordance with the preferred embodiment of the present invention demonstrating the proper placement of encapsulated dentifrice 118 in the first head reservoir 110 and second head reservoir 116. As referenced, first head reservoir 110 and second head reservoir 116 is designed to receive and retain dentifrice capsule 118. In this instance, dentifrice capsule 118 is spherical in shape and manufactured of slightly larger dimensions than dentifrice capsule 118 so that the user can forcibly place refillable dentifrice capsule 118 therein and first head reservoir 110 and second head reservoir 116 can thereby substantially retain rupturable dentifrice capsule 118 for proper use. It is further contemplated by the present invention that first head reservoir 110 and second head reservoir 116 may employ a cushioning effect so that upon acceptance of the dentifrice capsule 118 any excess pressure applied by the user may be counteracted thereby preventing premature eruption of dentifrice capsule 118. Dentifrice capsule 118 retains and applies the dentifrice therein in appropriate quantity onto first head bristles 108 and/or second head bristles 114 and corresponding channels of distribution (not shown) of first head 106 and/or second head 112, or other corresponding cleaning elements. The referenced dimensions can be of varied sizes designed to accept varied sizes of dentifrice capsule 118 or other oral care material. While the preferred embodiment of the present invention is designed to be a refillable implement, it is contemplated by the present invention that oral hygiene implement 100 may also be designed of suitable size for transport or single use as a disposable unit. Specifically, it is contemplated that oral hygiene unit 100 may be packaged in suitable form with a gel dentifrice, powder dentifrice, or the like, including combinations thereof that is readily transported, disposed, or utilized.
FIG. 2 depicts a bottom view in accordance with the preferred embodiment of the present invention exhibiting oral hygiene implement 100 comprising ergonomic elongated handle 120 and the placement of encapsulated dentifrice 118 in the first head 106 comprising first head reservoir 110 and first head bristles 108 positioned at a first end of elongated handle 120 and a second head 112 comprising second head reservoir 116 and second head bristles 114 positioned at opposing second end of elongated handle 120. Elongated handle 120 exhibit grip means 122 comprised of dimples, protrusions, concave formations, convex formations, ridges, and the like for improved control of the oral hygiene implement 100. It is further contemplated by the present invention that alternate grip means 122 may be employed such as thumb or digit prints, thumb or digit holes, suction mechanisms, or other like handle modifications to assist in improved grip by the user. One of ordinary skill in the art will readily recognize that substantial grip and stability is essential to the use of oral care devices as a means to protect the oral cavity and associated regions and limit damage to teeth and soft tissue as well as to assist in proper brushing of the region.
