Description

BACKGROUND OF THE INVENTION

1. Technical Field

This invention relates to toothbrushes that are used to clean the teeth of humans by repetitive scrubbing of the teeth and tongue scrapers that are used to scrap the upper surface of a human's tongue for increased oral hygiene.

2. Description of Prior Art

Prior art devices of this type are directed towards toothbrushes and tongue scrapers that have improved cleaning operation to allow for better brush cleaning and improved performance during use, see for example U.S. Pat. Nos. 2,438,268 and D282,318 for toothbrush configurations.

U.S. Pat. No. 2,438,268 is directed to a flexible bristle head toothbrush wherein a plurality of independent brush bristle support sections are secured together in parallel spaced relation to one another by a flexible connector element that extends through oppositely disposed portions of each section and attaches to a handle.

In Design Patent D282,318 a toothbrush head design is disclosed wherein a brush head has a single large opening therein surrounded by a plurality of bristles extending therefrom.

Examples of prior art patents having combined brush and tongue scraping elements can be seen in U.S. Pat. Nos. 5,758,380, 5,842,247, 6,273,719, D283,952 and D377,417.

In U.S. Pat. No. 5,758,380 a toothbrush is disclosed having a U-shaped scraper on the back of a bristle brush head.

In U.S. Pat. No. 5,842,247 a tongue cleaning brush with a toothbrush is shown.

In Pat. No. 6,273,719 an oral hygiene implement is illustrating having a brush on one end and a loop on the other end which acts as a tongue scraper.

In Design Patent 283,952 a combined toothbrush and tongue scraper is illustrated and in Design Patent 377,417 a toothbrush is shown on one end of a handle and a tongue scraper on the other.

Applicant's own U.S. Pat. No. 5,836,036 discloses a self-cleaning toothbrush on which the present invention is an improvement with the addition of an integral tongue scraper and improved bristle position and cleaning element pass through configurations.

SUMMARY OF THE INVENTION

A combination of a self-cleaning toothbrush and integral tongue scraper that has a plurality of brush bristle groups that are mounted in spaced relation to one another with multiple pass through cleaning openings therebetween.

A plurality of upstanding tongue scraper elements extend from the opposite side of the brush head adjacent the selected cleaning openings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 2 of the drawings, a self-cleaning tongue scraper toothbrush 10 can be seen having a handle portion 11 and a brush head portion 12 with a plurality of bristles 22 so indicated extending therefrom.

The brush head portion 12, as best seen in FIGS. 1, 3 and 4 of the drawings, has an outer perimeter support portion 14 that defines a generally rectangular shape thereof. A series of bristle mounting areas are defines within the brush head by multiple groups of aligned shaped cleaning openings 15, 16, 17, 18 and 19 therethrough. The bristle mounting areas are arranged in transverse and longitudinal patterns 20 and 21, as best seen in FIG. 3 of the drawings. A plurality of evenly spaced brush bristle bundles 22 shown in broken lines in FIGS. 4 and 5 of the drawings extend from corresponding mounting sockets 23 within the hereinbefore described transverse and longitudinal mounting patterns 20 and 21 on a brush head surface 24 surrounding the cleaning openings 15-19.

Each of the bristle retaining sockets 23 are of equal annular dimension and depth and are evenly spaced with respect to one another within the bristle mounting areas in the surface 24 of the brush head portion 12 as seen in FIG. 3 of the drawings.

The brush bristle bundles 22 so defined in their respective groups extends from the respective mounting sockets 23 may be of even or uneven length to provide an effective brushing pattern during use as will be well understood by those skilled in the art.

The open pass through nature of the brush head portion 12 imparted by the multiple cleaning openings 15-19 therethrough are adjacent the brush head bundle groups 22 assure the effective cleaning after use by creating an enhanced flow action of tap water as it passed therethrough indicated by directional flow arrows in FIG. 4 of the drawings, for example.

Referring now to FIGS. 1, 2 and 4 of the drawings, a plurality of upstanding tongue scraper elements 25 extend from brush head's top surface area 26 in oppositely disposed relation of the bristle bundles 22 as previously described. Each of the scraper elements 25 is comprised of an elongated bar portion 27 in spaced parallel relation to one another having oppositely disposed enlarged contoured ends 27A and 27B. Each of the hereinbefore described scraper elements 25 extend transversely across the brush head's top surface 26 and are positioned adjacent the respective pass through cleaning openings 15-19 to provide ease of cleaning after use as with the brush bristle bundles 22 as hereinbefore described.

The handle portion 11 of the toothbrush 10 of the invention is curved at 28 extending from the brush head portion 12 with a plurality of grip enhancement bands 29 thereon. The remaining handle portion at 29 is longitudinally tapered towards its free end at 30 which is angularly offset at 31.

It will be evident from the above description that a user (not shown) will have the advantage of a high performance toothbrush with self-cleaning action due to the cleaning openings 15-19. Additionally, the multiple tongue scraper elements 25 will enhance the oral hygiene effectiveness of the brush 10 by providing an integral tooth scraper which will allow for ease of use and cleaning as hereinbefore described.

It will thus be seen that a new and novel combination self-cleaning toothbrush and tongue scraper has been illustrated and described and it will be apparent to those skilled in the art that various changes and modifications may be made thereto without departing from the spirit of the invention.
