Abstract
A toothbrush with liquid-absorbing sponge structure (70) formed with a thickness diminishing to a pointed head which projects outwardly longitudinally from the bristle (50) whereby the absorbed liquid may be introduced into and along the rows of bristles. The sponge structure (70) carries substantially more liquid than the bristles alone and thereby irrigates the mouth while brushing and particularly upon repeated wetting of the brush.
Description
A "FOAM-O-GENIC" TOOTHBRUSH AND A GUM-MASSAGING
DEVICE BACKGROUND OF THE INVENTION :
This is an International (Patent Convention Treaty) Application for my allowed U.S. Application entitled "A Foam-Generating Toothbrush". Water is of paramount importance in most cleaning processes and cleaning the teeth (Oral Hygiene in general) is no exception. The conventional toothbrush (which was introduced some two hundred eleven years (211 years) ago being poorly or totally non-absorbent is incapable of carrying or conveying into the mouth cavity any significant amounts of water in comparison with the current invention. Insufficient water as carried by the conventional toothbrush results in substantially limiting the cleaning power of the conventional toothbrush. Furthermore,the bristle-design of the classical toothbrush is incapable of instantly generating copious amounts of cleansing foam during the process of brushing the teeth. It lags far behind the FoamBrush subject of the current invention. A toothpaste in order to exert any cleansing action, it must be converted into a mobile solution first. This is particularly true in order to clean the difficult or inaccessible areas of the mouth, such as in-between the teeth, nooks, cranies and crevices. Foam or suds is invaluable in cleaning in general, on account of its effective penetration into inaccessible areas of the mouth mentioned above on account of its huge surface area, high dirt-emulsifying/lifting & anti-sticking power on certain pigments,more importantly food particles, debris and plaq Foam has much lower surface tension. The extremely valuable measure of water absorbed by the FoamBrushes providing and making available an "irrigation factor" at the opportune moment while brushing the teeth is invaluable for practically everyone. However, it is indispensible for the people suffering from the condition known as dry mouth
Xerostomia whether temporary or chronic. Water is an excellent lubricant and further protects the gums and teeth against excessive chemical harshness of toothpastes and abrasive action of the bristles. This is accomplished through increased lubricity as mentioned above and the dilution effect on the detergents and soaps usually added to toothpastes and dentifrices. Foam is milder than equally-concentrated Soap or Detergent solution. BRIEF DESCRIPTION OF THE DRAWINGS :

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION : Referring to Fig.1-A,FoamBrush has 3-rows of bristles 50 which may be soft or extra-soft....etc. with handle 60 and fibrous/fibrocellular conical or pyramidal spongy structure 70 glued-on or mechanically-fitted to the tip,sides& back of the head of the toothbrush. Fig.1-B shows a back-view of same toothbrush where the sponge structure 70 is gluedon or mechanic-ally-fitted onto the tip, sides & back of the head 80. In the embodiment of Fιg.2-A ,the FoamBrush has 3 rows of bristles 50 and glued-on or mechanic-ally-fitted foam 70 encircling entire head 80. In Fig.3-A,a third embodiment has glued-on or mechanic-allyfittedfoam 70 completely encircling the 3-rows of bristles and handle-end 90. In the embodiment of Fig.4-A multiple laminated & conically-shaped foam is glued-on or mechanically-fitted thereon.
Fig.4-B : Shows a view of the back of the Foam-Toothbrush of Fig.4-A with multiple-layered rainbow-colored & glued-on or mechanic-ally-fittedfoam covering the upper two thirds of the back of the head of the brush 80.
In the embodiment of Fig.5-A two rows of bristles 50 have contiguous glued-on or mechanic-ally-fittedfoam 70 with handle 60 and handle-end 90.
In Fig.6-A : The Foam-Toothbrush has a circumference-row of bristles
50 completely surrounding glued-on or mechanic-ally-fittedfoam 70.
In Fig.7-A,the Foam-Toothbrush has three rows of bristles 50 with a glued-on or mechanic-ally-fittedconcal sponge 70 at one end& a non-bristle, conical foam at the other end. The side-views show the positions of the glued-on or mechanic-ally-fittedfoam-appendages 70 respectively and in relation to the Bristles-head 80 (or bristle-free tail-end 90 in case of Fig.7-C) of the Foam-Toothbrush and more importantly in relation to the brushing bristles 50 which enjoy total freedom from the foam. In operation, the Foam-Toothbrush is wetted well with warm (or tepid.) water, then the tooth-paste is applied to the bristles 50 and the sponge head 70, the latter providing an extra & highly absorbent area for securing an extra amount of toothpaste/gel. The toothbrush is then introduced into the mouth and brushing is commenced preferably with the mouth closed. It will be felt that the FoamBrush fits more comfortably against the teeth in general and the back-teeth in particular. In addition
copious amounts f foam will be instantly generated-, excess, for two main reasons:First, the significant amount of water carried on the sponge head 70. This water-instantly mixing with the toothpaste-contributes substantially to the build-up and mobility of the foam generated as explained earlier. Second: the fibrocellular design plus the trapped air-bubbles -the latter constituting 97% of the sponge mass- strongly promotes the instant & model - generation of myriads of foam bubbles. This extra foam which can be 4-5 times greater in quantity and higher in cleaning power than otherwise,bathes the teeth.gums & mouth cavity for a highly effective and cleansing Foam-Bath. Toothpastes/Gels apparently taste better when in the "Foam State" than in solution comparable to a solution of candy before and after being transformed into cotton candy. The latter in the foam state tastes uniquely better than in solution,although both solution and foam are chemically identical. The unplasant taste of toothpaste seems to be much milder, less unpleasant & mediciney in the foam state than in solution. In addition, the higher water content of the foam generated by the foam toothbrush contributes to this mildness by diluting the bitter taste of the toothpastes. Furthermore the higher water content enhances the flow and mobility, hence the penetration of the toothpaste/gel or dentifrice ingredients into otherwise inaccessible areas in the mouth cavity,such as in-between the teeth, cracks & crevices...etc. This contributes to much fetter and overall "all" tooth-surfaces cleaning and minimizes the buildup of "plaque material" and lessens significantly the chances of developing cavities, tooth decay&gingivitis with the dreaded tooth-loss that may ensue. The milder taste of the toothpastes/gels in the"foam-state" definitely encourages more brushing and lessens the common hate or phobia associated with brushing and toothpastes in general, especially by children and young adults. Furthermore, foam-having more body to it- seems to have a protective or cushioning effect on the gums against the often sharp, abrasive d\nd pointed ends of the bristles of the toothbrush. It will be noticed in brushing with the FoamBrush of Fig. 1-A & 1-B that the brush fits more comfortably in general against the teeth , particularly the back-teeth for the first time by virtue of the cushioning of the tip of the brush. This results in a more thorough and adequate brushing of the teeth in general and the back-teeth in particular. It should be mentioned here that the back-teeth are notoriously more vulnerable and susceptible to tooth decay than the front teeth. Also biggercavitieswhicharemore difficult to treat. The sponge- composition(s) in the different Foam-Toothbrushes described above may be advantageously & permanently pretreated with un-leaching (non-bleeding) antibacterial & anti-micrnbial agents during the process of manufacture. This pre-treatment,so as to chemically-bind these antibacterial&anti-microbial agents will render these sponge composition(s) highly resistant to "souring" and the development of any potentially harmful microbes, although these compositions are self-cleaning for all practical purposes during brushing of the teeth, rinsing immediately afterwards to be followed by sque zing-out /of excess water & rapid drying of these sponge compositions. Rapid drying of the highly-ventilatable sponge-compositions automatically discourages any such microbial development. The anti-microbial pre-treatment is for added protection and as a precautionary measure against any such develop¬ment or accident.
The foam-tail 70 of Fig.7-A,B&C Foambrush can be used for massaging (with or without dentifrices) and even cleaning,brushing & stimulating the gums & teeth of people with delicate &/or inflammed, painful & tender or bleeding & diseased gums,referred to as Periodontal disease by Dentists. If the Periodontal or gum condition persists, it may be advisable to switch to the bristles-free or Foam-Only TooStix subject of U.S. patent 4,576,190 mentioned above & a third co-pending patent application, a continuation-in-part for the TooStix patent.
It is understood that variations could be made on the embodiments described herein,without departing from the essential features of the invention and the preferred embodiments are not intended to limit the spirit or scope of the invention as set forth in the appended claims ,thus :
