TOOTHBRUSH WITH TONGUE CLEANER
A manual toothbrush has a handle with a head at one end of the handle having first and second opposing sides, the handle and head made of a first polymeric material. Nylon bristles are fixed to and extend from a first side of the head. A U shaped auxiliary member is made of a second polymeric material that is more flexible than the first polymeric material. The auxiliary member is co-molded with the head and extends partially around a periphery of the head with a first side of the auxiliary member adjacent the first side of the head. The auxiliary member includes a U shaped tongue cleaner projecting away from the second side of the head with an open side of the U facing the handle, and a plurality of projections projecting from the first side of the auxiliary member spaced apart from and substantially parallel to the nylon bristles.
This is Continuation-in Part of application Ser. No. 14/801,196 filed Jul. 16, 2015 which claims benefit of provisional application Ser. No. 62/161,819 filed May 14, 2015.
FIELD OF THE INVENTIONThe present invention relates to a toothbrush with an integral tongue cleaner.
BACKGROUND OF THE INVENTIONFor years, dentists have recommended that persons brush at least twice a day and floss once a day to maintain healthy teeth and gums, and to prevent bad breath. However, many oral care experts do not mention that a very high percentage of odor causing bacteria are found on the surface of the tongue. Some dentists recommend that their patients simply brush their tongue, as they do their teeth. However, this practice is very harsh and aggressive to the tongue, and can be very uncomfortable and unproductive.
Other inventions have attempted to solve this problem, however most have been very unsuccessful due to an array of reasons including for example: some prior art tongue cleaners, due to their irregular shape, can cause the user to experience a gagging-reflex and an abrasive feeling on the tongue's surface; and most tongue cleaners are expensive and difficult to manufacture, thus they are very uneconomical.
DISCUSSION OF THE PRIOR ARTU.S. Pat. No. 5,758,380 discloses a toothbrush provided with a U shaped tongue scraper. Other examples of toothbrushes equipped with tongue cleaners are disclosed in the following U.S. patent publications: U.S. Pat. Nos. 1,891,864; 4,455,704; 5,915,433; 6,647,581 B1; 8955190 B2; 20120167319 A1; 20140325778 A1; D 162941; D 246878; D 377417; D 265270; D 284528; D 285389; D 295695; D 423785; D 423786; and D 727626 S.
SUMMARY OF THE INVENTIONThere is provided in accordance with one aspect of the present invention a manual toothbrush has a handle with a head at one end of the handle having first and second opposing sides, the handle and head made of a first polymeric material. Nylon bristles are fixed to and extend from a first side of the head. A U shaped auxiliary member is made of a second polymeric material that is more flexible than the first polymeric material. The auxiliary member is co-molded with the head and extends partially around a periphery of the head with a first side of the auxiliary member adjacent the first side of the head. The auxiliary member includes a U shaped tongue cleaner projecting away from the second side of the head with an open side of the U facing the handle, and a plurality of projections projecting from the first side of the auxiliary member spaced apart from and substantially parallel to the nylon bristles.
Referring first to
The exemplary tongue cleaner 20 comprises a polymer that is relatively rigid. The polymer may be any suitable polymer selected in accordance with good engineering practices that does not have any adverse effects on the oral health of a user of the toothbrush. In the exemplary prototype illustrated in

Referring next to
A U shaped auxiliary member 219 comprises a second polymeric material that is more flexible than the first polymeric material of the handle 212 and head 213. The first and second polymeric materials may be any suitable polymer materials selected in accordance with good engineering practices that do not have any adverse effects on the oral health of a user of the toothbrush. The auxiliary member 219 is co-molded with the head 213 with the auxiliary member extending partially around a periphery of the head with a first side of the auxiliary member adjacent the first side of the head from which the nylon bristles 211 extend. As used herein and in the claims “co-molded” is understood to mean two components comprising two different polymeric materials that molded together as a unit in one process such as dual injection molding, two-shot molding, two color molding, two component molding and/or multi-shot molding. The auxiliary member 219 comprises a U shaped tongue cleaner 220 projecting away from the second side of the head with an open side of the U facing the handle as shown in
It is understood that an auxiliary member as disclosed may be combined with a manual toothbrush having a handle of any suitable shape and a head of any suitable shape, including rectangular, square or round.
While the invention has been described with reference to certain exemplary embodiments, obvious modifications and alterations are possible by those skilled in the related art. Therefore, it is intended that the invention include all such modifications and alterations to the full extent that they come within the scope of the following claims or the equivalents thereof.
Claims
1. A manual toothbrush comprising:
- (a) a handle with a head at one end of the handle having first and second opposing sides, the handle and head comprising a first polymeric material;
- (b) nylon bristles fixed to and extending from a first side of the head;
- (c) a U shaped auxiliary member comprising a second polymeric material that is more flexible than the first polymeric material, the auxiliary member being co-molded with the head, the auxiliary member extending partially around a periphery of the head with a first side of the auxiliary member adjacent the first side of the head, the auxiliary member comprises: (i) a U shaped tongue cleaner projecting away from the second side of the head with an open side of the U facing the handle; and (ii) a plurality of projections projecting from the first side of the auxiliary member spaced apart from and substantially parallel to the nylon bristles.
2. The manual toothbrush of claim 1 wherein the projections project from the first side of the auxiliary member a distance less than a distance the nylon bristles extend from the first side of the head.
3. The manual toothbrush of claim 1 wherein there are two rows of projections projecting from the first side of the auxiliary member and the nylon bristles extending from the head are at least in part located between the rows of projections projecting from the first side of the auxiliary member.
4. The manual toothbrush of claim 3 wherein the projections project from the first side of the auxiliary member a distance less than a distance the nylon bristles extend from the first side of the head.
