ORAL HYGIENE APPLIANCE
Abstract
An oral hygiene appliance for removing plaque from interior
surfaces of the mouth not adequately cleaned by conventional
tooth-brushing. The device comprises two V-shaped jackets pivotally
joined at one end by a pin. A flat elongate tongue scraper blade is
held by the pin at one end within a first jacket. The blade is
angularly moveable between a storage position within the jacket and
a use position exterior to the jacket. A flat spool swivels into
and out of the other jacket in a similar manner.

Description
BACKGROUND OF THE INVENTION
The present invention relates to oral hygiene apparatus, and
particularly to apparatus for removing plaque from interior
surfaces of the mouth.
Dentists have become increasingly aware of the role of plaque in
causing tooth decay. Plaque is a thin film of mucus which forms on
the interior surfaces of the mouth, and which contains bacteria
which is the actual cause of tooth decay. The bacteria in the
plaque is supplied by food and other matter ingested through the
mouth. Toothbrushing had long been considered the accepted method
of preventing tooth decay. However, toothbrushing is only fully
effective in cleaning the exposed surfaces of the teeth, and is not
completely effective in cleaning the interstices between adjacent
teeth. Hence, while toothbrushing removes plaque from the exposed
surfaces of the teeth, it does not effectively remove plaque from
the crevices between the teeth, nor from other surfaces of the
mouth.
Dentists are becoming more aware of the deficiencies of
toothbrushing in completely removing plaque from the teeth, and
additional methods for cleaning teeth which supplement
toothbrushing are now often recommended. One common method is to
use dental floss or dental tape, which is inserted between the
teeth and moved back and forth to clean the areas between the
teeth. Another approach is the use of a dental irrigator which
squirts a pulsating jet of water which cleans the areas between the
teeth. These methods have achieved success in removing some of the
plaque missed by toothbrusing, effectively cleaning the areas
between teeth.
A basic deficiency in the use of dental floss, dental tape, a
dental irrigator or like apparatus in removing plaque is that other
surfaces within the mouth also contain plaque. During ingestion of
food through the mouth, a layer of plaque is formed on all interior
surfaces of the mouth, particularly the tongue. When the tongue is
moved around the mouth, the layer of plaque on the tongue is
transferred to the teeth. Hence, the efforts involved in cleaning
the teeth through toothbrushing and the use of dental floss and
other apparatus is to a large extent obviated due to the layer of
plaque left on the tongue.
The use of tongue scrapers to clean the layer of plaque off the
tongue is well known, and several such devices exist in the prior
art. However, the devices presently available do not incorporate a
means of cleaning the areas between the teeth as well as the
tongue, to provide a thorough means of removing the plaque left by
toothbrushing. When a combination apparatus has been attempted, as
illustrated by the patent to Yao, U.S. Pat. No. 3,254,356 for a
combined toothbrush, tongue scraper and ear cleaner, the apparatus
provided no means for covering the tongue scraper when not in use.
For this reason, former oral hygiene apparatus employing a
combination of implements have not met with common acceptance.
SUMMARY OF THE INVENTION
The present invention provides oral hygiene apparatus for removing
plaque from interior surfaces of the mouth not adequately cleaned
by toothbrushing. The apparatus provides both a tongue scraper and
a flat elongate spool adapted to contain a length of dental tape
thereon. The scraper and the spool are pivotally attached within
V-shaped jackets, and are angularly moveable relative to the
jackets. When either of the implements is to be used, the scraper
or the spool can be pivoted out of its jacket, with the unused
implement remaining in its jacket.
With the present invention, plaque may be cleaned from both the
tongue and the areas between the teeth, thus providing a complete
supplement to toothbrushing. Both the scraper and the tape are
contained in a single apparatus so that a complete program of oral
hygiene can be accomplished with the single tool in combination
with the usual toothbrush. The apparatus is designed so that when
either the scraper or the dental tape are being used, the implement
not in use is contained in its jacket. Hence, the unused implement
is shielded from contact with the hands of the user.
The novel features which are believed to be characteristic of the
invention, both as to organization and method of operation,
together with further objects and advantages thereof will be better
understood from the following description considered in connection
with the accompanying drawings in which a preferred embodiment of
the invention is illustrated by way of example. It is to be
expressly understood, however, that the drawings are for the
purposes of illustration and description only and are not intended
as a definition of the limits of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring initially to FIG. 1, the apparatus 10 of the present
invention is illustrated with the tongue scraper blade portion 12
pivoted partially outwardly from its respective V-shaped jacket 14.
Tongue scraper 12 comprises an elongate strip which is flexible so
that it can be flexed for use, but is sufficiently rigid so that
each edge thereof can be used to scrape plaque from the tongue. A
spool of dental tape is contained within jacket 16, as will
hereinafter be illustrated. Tongue scraper 12, jacket 14 and jacket
16 are all pivotable about a common pin connection 18, so that
jackets 14 and 16 can be aligned with tongue scraper 12 extending
therefrom for use.
Referring next to FIG. 2, the apparatus 10 is illustrated with the
tongue scraper (not visible), stored in its respective V-shaped
jacket 14, but with the flat elongate spool 20 pivoted outwardly
from its respective V-shaped jacket 16. A length of dental tape 22
is wrapped around spool 20, and has a loose end 24 which fits into
slot 26 of spool 20. By grasping end 24, tape 22 can be removed
from slot 26 and unwound for cleaning the plaque from the areas
between teeth in the traditional manner.
The details of pin connection are illustrated by way of reference
to the cross-sectional elevation view of FIG. 3. A flat pin head 30
has a pin section 32 extending therefrom. Pin section 32 passes
through one of the ends of each of V-shaped jackets 14 and 16.
Also, pin section 32 passes through one of the ends of the tongue
scraper 12 and the flat elongate spool 20 pivotally securing those
ends in the ends of the respective jackets. A releasable member 34
is attachable to end section 32 opposite head 30, and presses the
sides of the jackets together to provide frictional engagement
between the scraper 12 and spool 20 and their respective jackets.
Member 34 is releasable in order that the apparatus can be
disassembled to allow for periodic replacement of spool 20 and
tongue scraper 12.
Storage of both the tongue scraper and the dental tape within
V-shaped jackets 14 and 16 is illustrated by way of reference to
FIG. 4. As is apparent from the figure, the apparatus 10 can easily
be placed in a medicine cabinet or other place of storage when not
in use, with the tongue scraper and the dental tape enclosed by
their respective jackets.
Use of the tongue scraper 12 is illustrated by way of reference to
FIG. 5. Tongue scraper 12 is pivoted out of its respective jacket
14, and empty jacket 14 is aligned with jacket 16, which contains
the dental tape. Tongue scraper 12 can then be grasped at both
ends, with one hand holding the jackets 14 and 16, and the other
hand holding the free end of the tongue scraper. In this manner,
tongue scraper 12 can be flexed into the position illustrated, and
the edges thereof used to scrape the plaque from the tongue. After
use of the tongue scraper, it can be replaced in jacket 14 and the
spool 20 of dental tape 22 pivoted outwardly for use.
While the preferred embodiment of the present invention has been
illustrated in detail, it is obvious that modifications and
adaptations of that embodiment will occur to those skilled in the
art. However, it is to be expressly undersood that such
modifications and adaptations are within the spirit and scope of
the present invention, as set forth in the following claims.
