DESCRIPTION OF THE PRIMARY AND PREFERRED EMBODIMENT

[0034] With reference now to the drawings, and in particular to FIG. 1 thereof, the fundamental concept of the new and improved oral care device embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

[0035] The present invention is a modified comprehensive oral care device. It is comprised of a plurality of components. Such components are individually configured and correlated with respect to each other so as to attain the desired objectives. It is to be mentioned here that the description of embodiments of the invention described herein, any reference to orientation or direction are merely intended for convenience of description and is not intended in any way to limit the scope of the present invention. Relative terminologies used, such as above, below, front, rear up, down lower, upper, horizontal, vertical, above, below, anterior, posterior, up, top, ventral, dorsal, and bottom as well as derivatives thereof (e.g., downwardly, upwardly, horizontally, etc.) should be construed to refer to the orientation as then described or as shown in the drawing under discussion. These relative terms are merely meant for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation unless explicitly indicated as such. Terms such as coupled, fabricated, connected, attached, affixed, interconnected, and similar refer to a relationship of structures which are secured or attached to one another either directly or indirectly.

[0036] In their broadest context, the invention is a modified tooth brush which includes a toothbrushing head which is attached to a long handle. The current invention is a retractable toothbrush head, manually upon desire. The main brush handle, later referred as brush handle, invests a cavity inside for holding the retracted tooth brush head handle. The toothbrush head handle is normally positioned at the front and under surface of the device. It can be retracted backward using a switch which is a modified rear part of the handle of brush head. The brush head has clusters of bristles arranged in groups at the front bottom surface of the brush head handle. The front of the main brush handle has a top surface modified by affixing thereto a soft elastomeric pad with tiny projections which act as a soft tongue cleaner. In addition, there are two mobile tongue cleaner extensions on either side. These extendable tongue cleaners are normally mounted at the middle part of the brush handle while the brush is used for brushing teeth. When it is used as a tongue or tissue cleaner, the toothbrush head is retracted backward and extendable tongue cleaners are mobilized by sliding and are mounted at the front end of the device. These retractable and extendable tongue cleaners are mounted as sliders on either side of front part of the brush handle with their cleaning surface in line with the tongue cleaner surface of the brush handle. The tongue cleaning surface of the brush handle has long curvilinear projections of soft bristles on both ends which act as tongue scrapers. The rest of the tongue cleaning surface acts as a collector of scraped debris, as well as acting as deep tissue cleaners and for massage with their numerous elastomeric projections of fine bristles. The extendable tongue cleaners also have similar, but longer, curvilinear elastomeric bristles mounted on their lateral aspects which can be used to scrape tongue or tissues from side to side or at angles. Moreover, they also have tiny elastomeric bristles as in the main tongue cleaning surface for deep brushing, massaging and cleaning.

[0037] The toothbrush head brushing bristles on retraction are securely covered by an envelope firmly fixed with the handle. This toothbrush envelope may be made of similar or transparent tough elastomeric material. The tongue cleaning surface is covered by a. stretchable, soft elastomeric cap which can be easily removed while brushing as needed. The device can be stored in any suitable container or it can be hung using the hanging thread attached at the rear end of the device.

[0038] The primary embodiment of the invention is an oral care device which is a hygienic, ergonomic, handy, and convenient oral care device adapted to clean an oral cavity, especially the teeth and the tongue surface. It has a brush head 10 which holds a series of bristles 11 arranged at the ventral surface towards the front end. The brush head has a long handle 12. The toothbrush bristles are made of durable fibers which may be arranged in bundles of any size, shape, or distribution. They can be of any strengthsoft, firm, or hard bristlesdepending on the specific need. They can also be any type or combination of materials, such as nylon fibers, elastomers, or rubber of different sizes, shapes, and forms. The brush head handle and most of the brush handle can be made of any suitable, firm elastomeric material of any color, constitution, or combinations. The brush head along with its handle is retractable and the entire assembly can be moved backward. This backward movement is aided by a switch like projection 13 of the terminal part of the brush head handle. The brush head switch is exposed on the top of the main brush handle. The brush head assembly can be retracted backward and encased within a hollow space 16 at the middle of the main brush handle 15. The distal end of brush head handle is modified suitably 14 to get locked in position for the purpose of brushing. This locking prevents any frontward or backward movement of the brush head on normal brushing position.

[0039] The primary embodiment of the oral care device has a main brush handle which is long and covers the entire brush which is about 10 mm+/4 mm wide, 10 mm+/4 mm thick, and 180+/20 mm long. On the front part, it is divided into two horizontal halves, one forms the brush head and its handle assembly as described above and the other top half 18 which is modified on the front aspect. This modified front aspect on the top surface is covered by a soft elastomeric pad which acts as a non-traumatic tongue or tissue cleaning surface 19. This primary tongue cleaning surface measures approximately 35 mm+/5 mm long, 10+/4 mm wide. The toothbrush head area with bristles measures 30 mm+/5 mm long, and 10+/4 mm wide. The tongue cleaning surface has numerous tiny projections or bristles measuring 1+/0.5 mm tall so as to allow deep cleaning of the papillary surface of tongue. The tongue cleaning surface is covered by a stretchable elastomeric cap 23 which covers the tongue cleaning head surface and which can be removed while brushing. The primary embodiment also has a circular or oval thread 22 acting as a hanger attached to the distal end of the brush handle which is fitted around an opening 21 made at one corner of the distal end of brush handle. When the brush head handle assembly is retracted fully; the brush head is fully encased within a brush head envelope 25 which is firmly attached with the main brush handle. The brush head envelope is made of tough elastomeric material. The brush head envelope is ideally transparent. The brush head envelope is open on the side facing the brush bristles on the front 24 and is closed on the distal end 26. It has two lateral outer surfaces 69 and five inner surfaces 68 with a covered posterior surface 71. The toothbrush head envelope measures 35 mm+/5 mm long, 12+/4 mm wide, and 10+/4 mm tall.

[0040] The tongue cleaning surface of the primary embodiment has numerous thin (1+/0.5 mm) bristles 30 on its top surface. In addition to the main tongue cleaning surface, there are two additional expandable tongue cleaners 28 attached on either side of the main brush handle towards its top end. These expandable tongue cleaners also have cleaning bristles on their surface 29. These expandable tongue cleaners are normally positioned at the mid-part of the handle. They have lateral margins 27 which have a grooved surface to provide a grip for sliding movement. These expandable tongue cleaners can be moved by fingers while using as a tongue cleaner and are glided through a shallow grove 31 on either side of front part of main brush handle.

[0041] The brush head handle of the primary embodiment has a long handle 38 which is modified at the distal end 35. The distal end of the brush head handle is locked normally at a projection 32 of the anterior part of the brush head cavity wall anteriorly 34 which are essentially part of the main handle body. The switch part of the brush handle assembly is attached to the main body by a long narrow band 33 which is wedged inside the cleft for the handle switch while most of the switch is situated above the top surface of the main brush handle. The normally engaging part of the distal end 35 can be pressed downward by pressing the switch so that the tip end 37 and engaging end get unlocked from the anterior end of the upper part of the brush head cavity 53. In this manner, by pressing and moving backward of the switch, the entire brush head assembly can be moved backward until the whole of the brush head area is inside the envelope for the brush head. The brush head cavity is thus at a lower level on the posterior aspect on its roof 55 and floor 54 compared to the narrow area of brush head cavity anteriorly. The switch which has an anterior extension 51 and a posterior extension 52 assist the pressing movements. The switch is fixed by the connecting bar with the body 50.

[0042] The top surface of the handle has a deep slit 47 extending across the surface to the brush head cavity. It ends as a smooth curve anteriorly. A part of it is covered by the switch area 46 and ends blindly at distal end 48. The top surface of the device mounts the main and extendable tongue cleaning areas. The primary embodiment of main tongue cleaner area 41 has a semicircular projection or scraper bristle made of the same or similar material as the tongue cleaner pad anteriorly 42 and posteriorly 43. They are taller than other finer bristles 40 on the tongue cleaner surface by 0.5+/0.3 mm. These act as soft non-traumatic tongue scrapers. Similar, but longer, semicircular scraper bristles are seen on both expandable tongue cleaners 45 projecting about 0.5+/0.3 mm taller than the other bristles 44. These semicircular scrapers act like conventional blade scrapers in regard to sweeping action on debris, but are non-traumatic. They are located at the peripheral part of the tongue cleaner device and are taller than other bristles on the tongue cleaner. This help as an excellent scraping tool and aids collection of more debris than the bristle composition. Moreover these projecting small surface area scrapers can aid to clean even the most posterior aspect of the tongue surface in those people with gagging problem. Brushing with a relatively large and flat surface provokes more gagging stimulating more nerve endings. Therefore, this arrangement can aid even sensitive people to have a fair tongue and tissue cleaning who are also more vulnerable for halitosis from excess tongue coating. Also completely retracting the brush head while cleaning the tongue and tissues, avoids irritation of the palate and pharynx by the otherwise tall bristles of usual tooth brush with tongue cleaners. When the expandable tongue cleaners are mounted firmly anteriorly 49 on the main tongue cleaner, the whole assembly acts as an extended tongue cleaner with a large surface, not available with conventional toothbrush mounted tongue brush scrapers. The gap between the tiny bristles of the tongue cleaners acts as space for collection of debris and can be washed clean easily by water. Thus, the retractable brush head and expandable tongue cleaners act as an effective and beneficial tool for safe and ergonomic dental and tissue cleaning for the entire population, significantly free from gagging and similar uneasiness which may preclude proper use of a conventional toothbrush.

[0043] The primary embodiment of the tongue cleaner head cap 23 is a tightly fitting, stretchable, soft elastomeric cap covering the tongue cleaning surface. It has an open anterior (front facing) end 59 which is open and a covered blunt end posteriorly 56. It has an open stretchable lower margin 58 to insert into the tongue cleaner head area and a closed top surface 57 covering the surface from dust and dirt. The primary embodiment of the expandable tongue cleaner is a slidable device fitted on either side of the main brush handle towards the upper and anterior part. It has an upper surface 60 acting as a cleaning surface and a lower surface 61 and lateral margin 62 which is grooved for allowing grip for sliding movement. The device is invested into a shallow groove of lateral surfaces of the brush handle with a narrow band 63 going deep into the groove and locking inside by two marginal projections superiorly 64 and inferiorly 65.

[0044] The preferred embodiment of the expandable tongue cleaner has a length of about 35+/10 mm and a 5+/3 mm maximum width at the center. The cleaning surface of the preferred embodiment has three rows of cylindrical fine bristles 56 which are 0.5 mm+/0.3 mm tall and 1 mm+/0.5 mm in diameter. These rows of cleaning bristles are arranged with gaps in between and with the semi-circular scraper bristle. The gliding grove for the expandable tongue cleaners are uniform in depth except at ends where they are deeper anteriorly 129 and posteriorly 130 and abrupt so as to lock from over movement and step out of the groove.

[0045] The cleaning surface of the main tongue cleaner surface and expandable tongue cleaners when mounted together act as a large semi-oval tongue cleaning surface. The system is sufficient enough to scrape, deep clean, and collect the debris accumulated over the entire tongue surface. The preferred embodiment of the main tongue cleaning surface has numerous tiny projections to be called bristles. They are distributed in particular fashion on the surface and have different shapes and configurations. Two relatively large and taller semicircular bristles on both ends of the cleaning surface are described along with primary embodiment.

[0046] In addition, the preferred embodiment features two similar semi-circular bristles 125, 126 arranged facing each other and off the center of the tongue cleaning surface. These semicircular bristles are concave-convex relatively firm elastomeric projections fashioned from the surface of the tongue cleaner pad with an outer convex surface 112 and inner concave surface 111. The summit 113 of these bristles is smoothly curved for ensuring firmness and smooth movement.

[0047] In addition numerous tiny cylindrical or filiform bristles 123 are arranged in groups of circles at the center, main tongue cleaner surface, and on expandable tongue cleaners. These bristles are fashioned projecting from a base 102 with a tall body 103 and a smooth curved top end 104. Such rows are arranged in layers alternating with rows of triangular pyramidal bristles 124 on the main tongue cleaner surface. These pyramidal bristles arise from a base 105 with three triangular surfaces 106 with a curved and smooth summit 107. Four curvilinear bristles are arranged in a circle at the center. These curvilinear bristles 127 are three dimensional projections arising from the base 108 with multiple ridges 109, 110 on their surface forming firm cleaning surfaces. Different geometrical shapes allow accommodation with papilla and clefts of different sizes and allow better cleaning. Also the centripetal arrangement of all bristles allows thorough cleaning on any front-back and side-to-side movement of tongue cleaner and allows collection of debris towards the center which can be cleaned easily on running water. In this manner, the extensive scheme of bristle combinations and arrangement ensure scraping as well as thorough cleaning and collection of debris from tongue surface. Also, these features offer different levels of cleaning as tolerated by the user including those with severe gagging who can just tolerate gentle sweeping of debris with scraper bristles to those desiring very thorough but comfortable cleaning of tongue or other tissues.

[0048] The toothbrush head when mounted at the tip of brush assembly is firmly locked of all movements as long as the switch is not applied. The brush head which is bearing the cleaning bristles is kept as small as possible to avoid mucosal injury including gum, bucco-gingival cleft and minimal touching of pharyngeal and palatal tissues. Its surfaces are smooth and curved at the tip surface. Bristles are short as possible but long enough to ensure thorough interdental cleaning. For effective and safe dental cleaning, the preferred embodiment is fashioned with an ergonomic design of bristles. There is an outer row of bristle bundles 73 covering all circumferences of brush head. These bundles are about 1 mm+/3 mm in diameter and 12+/3 mm tall from the surface of brush head handle. These bristles are made of strong fibers but with soft smoothly cut edges to protect the gums and oral tissue. On the inner aspect, there is a pair of four rows of firm bristle bundles 74 which are shorter than the outer bristles for 2-6 mm. There are four large bundles of firm bristles 75 arranged in alternate with these firm bristle bundles. These bundles are thicker in diameter 1.5 mm+/0.5 mm and are made of stronger fiber material and with narrow diameter bristles so as to penetrate and clean deeply into the fissures, cavities, and interdental spaces and to act like flosses. The outer ring 67 of soft bristle bundles is better equipped to engage with the convex surface of teeth with longer bristles. They'are strengthened by inner rows of V-shaped arrangement of firm bristle bundles arranged in four rows. The pair of firm bristle bundles are of the same diameter as the outer ring bundles forms the top of a V-shape 68 and the large bristle bundle form the junction of the V-shape 69. This V-shaped arrangement of central bristle bundles ensures thorough cleaning while the brush is moved to and fro with maximum engagement, as well as leaving large spaces between bristle bundles to form large lather bubbles and later aid for collection of debris. Thus, the preferred embodiment of the toothbrush configuration ensures a safe and thorough cleaning of teeth including the most difficult areas including cavities, dental fissures, and interdental spaces.

[0049] The preferred embodiment of the hanging thread is a double looped thread with a loop 97 attached to the opening for the hanger and another freely mobile loop 98 whose size can be adjusted depending on the caliber of hanging hooks or poles which are interconnected through a hanger's type knot 96. Thus, the preferred hanger is a simple thread or a wire loop suitably color matched with the brush handle. The length of the loop can be adjusted for different caliber hooks into which it can be hung if needed.

[0050] The preferred embodiment of the handle is configured for easy handling, comfort, firm grip, and aesthetics. The brush handle needs to be flip flopped from brushing teeth to tongue cleaning. Therefore, it is configured for holding with the fingers ensuring firm and comfortable grasp while used as tooth brush or as a tongue cleaner. All margins of the handle assembly are made of firm elastomeric material with a smooth finish and smooth margins. In addition, part of the upper surface of the handle is fabricated with a soft, flexible, colorful elastomeric material 72, such as soft acrylic for a strong and soft comfortable grip. A thin coat of similar material is fabricated over the top surface of the switch 67 and under the surface of the brush head envelope 70. The ventral aspect of the brush head envelope, which is the holding or grasping surface, is fabricated with the soft elastomeric material on most of the center 80 and these areas are furnished with numerous small semi oval projections 81 for a strong grip from slippage. The margins are also furnished by a thin coat of soft elastomer 79. Finger holding or thumb pressing needs to be done over the envelope for firm grip as is occupying the middle part of brush handle. The rest of the distal part of the brush handle on the ventral surface is furnished with a curvilinear firm elastomeric band 83 with marginal oval configurations 84 connected by curvilinear connecting bands 85. This is for aiding grip, adding strength, and for decorative purpose.

[0051] The top or dorsal surface of brush handle is fabricated with soft elastomeric material on both of its margins in a wavy fashion 114. They form a large curved surface anteriorly 115 with a grove for the switch 116. The switch becomes jammed firmly within this grove. Posteriorly towards the rear end of the handle, these wavy soft elastomeric pads are broadened 120 on both sides and end 121 just before the terminal bulge of the brush handle. The top surface over the cleft for switch is partly covered by a band of soft elastomeric rubber like band 117 which allows stretching when the switch is slid along the slit and mostly covers the cleft normally avoiding exposure of the defect. Also similar to ventral surface, firm elastomeric bands 118 with small curvilinear attachments are arranged on either side of the slit. These are mostly for grip and decorative purposes. The switch with coating of soft elastomeric material over top 119 is mostly camouflaged with the rest of the surroundings avoiding undue attention. Thus, the brush handle is fabricated with multiple elastomeric materials coupled with main body to get better ergonomic handling and aesthetic appeal.

[0052] The unique features of the invention include: 1) A retractable tooth brush head assembly; 2) An expandable mobile tongue cleaner assembly; 3) A stretch moldable cap for tongue cleaner surface; 4) A hygienic and grip enhancing enclosure for brush head; 5) Ergonomic handle for easy and comfortable use; 6) Unique bristle arrangement of tooth brush head for safe and thorough cleaning of teeth; 7) Aesthetic value of device; 8) Adjustable hanger thread; and 9) Gag free tongue cleaning with a plastic non-traumatic tongue scraper cum cleaner allowing cleaning of even most posterior part of tongue surface.

[0053] From a specific standpoint, the oral care device of the present invention is reconfigurable between an extended orientation for brushing teeth and a retracted orientation for wiping clean tongue and tissue. The brushing teeth and the wiping clean of the tongue and tissue are done in a safe, sanitary, convenient, and economical manner. First provided is a handle assembly. The handle assembly has an upper main brush handle 18 and a lower brush head handle 12. The main brush handle has an upper surface and a lower surface. The brush handle also has an upper surface and a lower surface. The handle assembly has a forward end and a rearward end. A hollow space 16 extends rearward from the frontward end of the main brush handle.

[0054] Next provided is a brush head. The brush head is formed of a plurality of bristles 11 for brushing teeth. The bristles depend downwardly from the lower surface of the brush head handle adjacent to the forward end.

[0055] A soft elastomeric pad 19 is next provided. The soft elastomeric pad is coupled to the upper surface of the main brush handle. The soft elastomeric pad is formed of a plurality of projections which are 1.0 mm, plus or minus 0.5 mm, in height. The soft elastomeric pad is for wiping the user's tongue and tissue. The projections extend upwardly from the upper surface of the main brush handle adjacent to the forward end.

[0056] Also provided are a pair of extendable tongue cleaner pads which are usually kept at an intermediate position of the main handle on either side. They are slidable along their slot on the lateral surfaces of the main brush handle and can be locked towards the forward end forming a composite large tongue cleaner with an oval configuration 49.

[0057] Next provided is a moving assembly. The moving assembly includes a T-shaped cap 12 and a slot 47. The slot is formed in the main brush handle extending vertically between the upper surface and the lower surface.
