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 1 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 US. 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 tooth- O brushes 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.
BRIEF DESCRIPTION OF THE DRAWINGS brush holder of this invention, cut out to show aperture-scrubber detail.
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 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 side walls 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 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 1 1, 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 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 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.
