Description
BACKGROUND OF THE INVENTION
This invention relates to an improved receptacle for toothbrushes.
In particular, this invention is directed to the problems with
dental hygene of presently available equipment.
The bathroom of the typical home is a breeding place for bacteria.
The typical toothbrush holder supplied with the house provides
essentially no protection from surrounding bacteria. Small children
may easily play with the toothbrushes of the family allowing them
to contact germs and bacteria throughout the bathroom. When the
toothbrush is replaced in the holder, the bacteria culture is left
free to multiply and become a menace to health.
An additional object of this invention is directed to the
toothbrush after use. After brushing the teeth, it is not uncommon
for food particulate to remain on the toothbrush along with other
deposits from the mouth. These deposits, if left alone, provide an
efficient breeding ground for bacteria. Thus, the toothbrush itself
is a source of contamination to the mouth.
In addition, this invention is directed to the harm that a dry
toothbrush can inflict on the gums of the person brushing his
teeth. A toothbrush left in the air for a number of hours will
completely dry out leaving the bristles stiff and unyielding. It is
recognized that if the toothbrush is not used in exactly the proper
manner, the gums can be scratched and damaged by a rigid unyielding
toothbrush bristle. It is therefore, an object to maintain the
toothbrush bristles in a soft pliable condition between uses, and
in combination protect the user from contamination of bacteria,
molds and other forms of microscopic life which can breed on a damp
toothbrush.
It is also an object to maintain complete separation of the
toothbrushes of a family from each other. This prevents the spread
of disease and contamination from member to member of the family.
It is also an object to provide an antiseptic flushing action
within the apparatus to clean the toothbrush.
Prior art devices have not solved the problems enumerated above.
The typical toothbrush holder on the wall or in the wall of new
homes fails to satisfy any of the needs described above. Other
toothbrush holders satisfy some but not all of the needs enumerated
above. Prior toothbrush holders include those described in U.S.
Pat. Nos. 1,566,860 to Hainzigianis of Dec. 22, 1925, 2,012,685 to
Laposea of Aug. 27, 1935, 2,474,621 to Federico of June 28, 1949,
3,141,712 to Holmes, et al of July 21, 1964, 880,432 to Weidhaas,
Jr. of Feb. 25, 1908, 1,507,446 to Collins of Sept. 2, 1924 and
1,584,261 to Vuolo of May 11, 1926. Some of these patents disclose
vapor sterilization but do not offer the advantage of the softened
bristles. Others do not provide any sterilization at all but only
provide compartmentalization. None provide a flushing action to
remove sediment from the holder and clean the toothbrush.
While these holders do not satisfy the above needs, the invention
described hereinbelow satisfies all the needs to provide a
sanitized, separated, and pliable toothbrush for every
brushing.
SUMMARY OF THE INVENTION
The toothbrush holder system of this invention is basically first a
compartmentalized cup shaped body having a plurality of
compartments which are adapted to contain antiseptic fluid and
prevent the flow of the fluid between the compartments. Secondly,
the invention includes toothbrush holders, one for each of the
compartments, which are adapted to hold individual toothbrushes and
allow the insertion of the toothbrushes into the individual
compartments to immerse the bristles in the antiseptic fluid for
storage between use. There are apertures provided in the bottom of
each toothbrush holder to allow fluid flow of the antiseptic fluid
into the toothbrush holder to flush and clean the toothbrush held
therein and to clean out the holder of any sediment or food
particulate that have settled in the holder. The toothbrush holders
are kept from entering into any other compartments so as to prevent
intermixing of the antiseptic fluid carried by the holders and
brushes.
Therefore, this invention provides for complete separation of the
toothbrushes and storage in an antiseptic fluid. It allows for
removal of the toothbrush to be used and reinsertion into the
holding system without intermixing between compartments.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
This invention comprises a body generally in the form of a cup
which may be constructed out of clear plastic to allow the user to
easily see his toothbrush. In any case, the body is constructed
with a solid bottom wall and vertical walls, which may be joined
and curved to form a continuous vertical wall. Inside the body,
there are provided a plurality of compartments sealed from each
other such that there can be no fluid flow between the
compartments. These compartments are adapted to contain antiseptic
fluid, although one or more of the compartments may be left empty
when not in use. Typically, these compartments are formed by
internal vertical walls extending generally from the center of the
body outwardly and joining with the outside wall of the body. At
the center of the body, where the vertical compartment walls meet
there preferably is a rod extending above the height of the
compartment walls to provide a guide for a toothbrush holder system
to slide upon. The height of the compartment walls is less than the
outside body wall and is typically about two-thirds the length of
the standard toothbrush. It is preferred that there be three to
five compartments.
Into this body is fitted the toothbrush holder system which
comprises a plurality of holders, one for each compartment. Each
holder is perforated at the bottom to allow the antiseptic fluid to
flow and squirt through the apertures washing the brush and
cleaning sediment and particulate out of the holder. The holder is
preferably held off the bottom of the body so as to allow
collection of sediment and particulate outside of the holder on the
bottom of the body. It is preferred that the individual toothbrush
holders, which may be generally described as baskets, have a
cross-section that essentially completely fills the inside
dimensions of each compartment, so as to increase the fluid flow
through the apertures when the holder is emersed in the antiseptic
fluid.
A preferred toothbrush holder system comprises a perforated bottom
on which are attached sidewalls, which extend vertically and abut
against the interior of the body walls. At least one of the
sidewalls must extend higher than the compartment walls so as to
join with other toothbrush holder walls above the compartment walls
holding the antiseptic fluid for strength and stability, it is
preferred that all interior walls of holder extend above the body
walls and join with adjoining holder walls. Thus, in this preferred
embodiment adjacent sidewalls of the toothbrush holders join at a
height above the compartment walls and allow sufficient space
between these adjacent sidewalls to allow them to slide over the
compartment walls. Typically the joined adjacent sidewalls of the
toothbrush holder extend upwardly and connect to a cover which fits
over the cup opening of the body.
Where the sidewalls of the toothbrush holders approach the center
of the compartment, sufficient room is left so as to allow space at
that center for a guiding rod which extends vertically at the
intersection of the compartment walls. Since this guide rod extends
above the compartment walls, there is a provision of a hole in the
center of the joined adjacent holder walls to allow the entire
toothbrush holding system to slide over the guide rod and the
compartment walls in and out of the antiseptic fluid.
Although the embodiment described hereinafter illustrates outside
holder sidewalls abutting the inside surface of the outside wall of
the body, these walls are clearly not necessary as the toothbrushes
can easily be lifted out of the solution without these walls being
present. It is preferred that that wall be present for rigidity of
the system and to prevent of jamming. Obviously all walls of the
holders may be perforated.
Referring now to FIG. 1 transparent body 10 consists of bottom 11
and vertical cylindrical sidewall 12. Compartment walls 13 are
sealed to bottom 11 and sidewall 12 such that each compartment is
fluid tight. Guide rod 14 extends above the height of compartment
walls 13 a sufficient distance to provide a guide for sliding
toothbrush holder system 20 up and down so as to lift out and
emerse the toothbrushes in antiseptic fluid present in the
compartments. Guide rod 14 acts as a reinforcing rod sealably
attached to compartment walls 13 and bottom 11.
Body 10 can obviously be composed of one molded piece, typically of
a plastic polymer. It is preferred that this entire body including
the compartment walls be transparent to allow the user to easily
pick his toothbrush, although this is not critical as when the
toothbrushes are lifted out of the fluid the color is easily
distinguished. The body may be composed of any material resistent
to degradation in continuous contact with antiseptic fluids.
Thermoplastic polymers are preferred such as polystyrene,
polymethyl methacrylate, polycarbonate, and other generally rigid
thermplastic polymers.
While the system may sit on a sink or a table, it is preferably
mounted on the wall by providing an indentation 15 in the center of
the bottom surface of bottom into which a rounded vertical rod
(shadow) is seated. Body 10 rests on this rod and is prevented from
falling by circular holder 16 around wall 12 but is allowed to
rotate on the vertical rod for easy removal of the
toothbrushes.
Continuing to refer to FIG. 1, toothbrush holder system 20 is shown
completely outside body 10. In use, holder 20 is generally not
removed from body 10 but is only lifted upwardly a sufficient
distance to allow removal of a toothbrush. Typically, a stop is
provided to prevent inadvertent removal of the toothbrush holder
system 20. However, the toothbrush holder system is entirely
removable when it is necessary to change the antiseptic fluid and
clean the holder.
The embodiment of FIG. 1 of the toothbrush holder system of this
invention consists of four separate holders 21, each fitting into
the body compartments formed by walls 12 and 13. Detail of the
holders is provided in FIG. 2, a cross-sectional view of lower
holder system. Holders 21 consist of perforated bottom 22 and
sidewalls 23 and 28. In this embodiment sidewall 24 is also
provided which extends only a short distance vertically and remains
emersed in the antiseptic fluid. On the other hand vertical
sidewalls 23 and 28 extend vertically to a height higher than the
compartment walls 13. At that height, it is preferred that the
sidewalls of adjacent holders, such as 23 and 25 join together to
form a solid single vertical wall 27. This joining is further shown
on FIG. 5 as an enlarged perspective view of these vertical walls
23 and 25 joining to form wall 27. There is sufficient area of
bottom 22 to allow a toothbrush to rest with the bristles placed
downwardly in the holder. Toothbrush T rests on bottom walls 22 and
is held vertically by resting against holder walls 23 and 28, or
the interior of body wall 12. In this embodiment the toothbrush
never touches wall 13, although it would touch if only one of the
holder walls were extended above the compartment walls.
Apertures 33 provided in bottom 22 are sufficient size to allow
fluid flow in and out of the holder. The aperture size is chosen to
provide sufficient resistance when holder 20 is inserted into the
fluid to provide a violent agitation of the fluid through the
apertures and around the toothbrush so as to clean the bristles and
wash out the holder. When holder 20 is raised, the apertures should
be of sufficient size to allow essentially complete drainage out of
the holder so as to provide fluid for subsequent agitation when the
holder is lowered. The drainage also carries sediment out of the
holder to body 10.
Referring to FIG. 2, as well as FIG. 5, space 29 between adjacent
sidewalls of toothbrush holders 21 is sufficient to allow the
holders to slide over and inside compartment walls 13. It is
preferred that space 29 be limited so as to allow the cross-section
of each holder to essentially completely fill each compartment.
Space 30 is provided to allow toothbrush holder 21 to slide over
guide rod 14 both at a height above compartment walls 13 and
below.
Again, referring to FIG. 1, wall 27 and other like walls extend
vertically and attach to cover 31. Knob 32 is provided for ease of
removal and is rigidly attached to cover 31 and walls 27.
The bottom of holders 21 are preferably not allowed to touch body
bottom 11, so as to allow a space for collection of sediment. This
may be accomplished by limiting the height of space 29 so that the
top of the space rests on the top of compartment walls 13, or by
providing a stop, like top 31 resting on the top of wall 12, or by
both. Of course, projections, like bumps, may be provided on the
bottom of holders 21 to allow for a space between bottom 11 and
holder bottoms 22.
FIG. 3 is an expanded cross-sectional view of the upper portion of
toothbrush holder system 20. Walls 27 are solid except for hole 34
which allows toothbrush holder system 20 to slide over guide rod
14.
FIG. 4 shows a cross-sectional view of body 10 wherein cylindrical
wall 12 forms a cup shape with bottom wall 11 and compartment walls
13 join with wall 12 to form individual sealed compartments. The
compartment walls 13 join at the center to guide rod 14.
The toothbrush holders 29 may be composed of one or two molded
pieces. It is preferred that holder 20 be molded of thermoplastic
polymer of the semi-rigid variety. It may be somewhat more flexible
than body 10, but it may be composed of the same material. Typical
satisfactory compositions for molding the toothbrush holder system
include polystyrene, polypropylene, polyethylene,
polyacrylonitrile-butadiene-styrene, and the like.
While this invention has been described with reference to the
specific embodiments disclosed herein, it is not confined to the
details set forth and the patent is intended to include
modifications and changes which may come within and extend from the
following claims.
