Sanitary toothbrush holder

Abstract

A toothbrush holder facilitates air drying of the toothbrush bristles after use while maintaining the surrounding areas sanitary if fluid drips from the bristles. The holder includes a base and first and second aligned posts extending upwardly from the base, each post having a top surface, the top surfaces configured to support a toothbrush handle. The second post top surface is spaced further from the base than the first post top surface so that an imaginary straight line between the top surfaces has a cant angle of about 4-10 degrees so that when a toothbrush handle is placed on the post top surfaces the toothbrush bristles are lower than the end of the handle most remote from the bristles. The base is positioned over a sink so that any fluid dripping from the toothbrush bristles goes directly into the sink bowl.

DETAILED DESCRIPTION OF THE DRAWINGS

[0017] FIGS. 1 & 2 show two exemplary holders 10 according to the present invention; the left holder 10 has a conventional toothbrush 12 mounted thereon, and the right holder 10 has no mounted toothbrush. Each holder 10 comprises a base 14 with first and second substantially aligned support structures. While the support structures may be bars, ledges, or have a number of other configurations, preferably the support structures are in the form of discrete posts 16, 17 as illustrated in the drawings, extending upwardly from the base 14. The first post 16 has a first top surface 18 and the second post 17 has a second top surface 19. As clearly seen in FIGS. 1-3 the post 16, 17 first and second top surfaces 18, 19, respectively, are each configured to support a handle 22 of the toothbrush 12. As also can be seen in FIGS. 1-4 the second top surface 19 is spaced further from the base 14 than the first top surface so that an imaginary straight line (such as that provided by a centerline of the toothbrush handle 22) between the top surfaces 18, 19 has a cant angle α (see FIG. 4) of at least about two degrees so that when a toothbrush handle 22 is placed on the top surfaces 18, 19 the toothbrush head 24, containing the bristles 26, is lower than the end 27 of the handle 22 most remote from the head 24.

[0018] While the cant angle α is at least about two degrees it is preferably about 4-10 degrees, and most desirably about seven degrees. Even though a 4-10 degree cant angle α is preferred the angle α can be significantly higher. However, if the angle α is more than about 40 degrees it is desirable to have some sort of retaining-mechanism to hold it in place so that it does not slide off of the posts 16, 17. The retaining-mechanism may be friction material at the tops 18, 19, an elastic band, or some sort of clip or latch.

[0019] While only two substantially aligned posts (or other supporting structures) 16, 17 are provided in the holder 10 in FIGS. 1-4 three or even more aligned posts may be provided depending upon the construction of the posts, such as the two sets of posts 16, 17 and 16′, 17′ in FIG. 5. In any case a toothbrush 12 held by the posts, regardless of how many, makes an angle α of at least about two degrees, with the toothbrush bristles 26 lower than the far end 27 of the handle 22.

[0020] As most clearly seen in FIGS. 1-3, the top surfaces 18, 19 may be configured to have longitudinal curved depressions 29 (like element 34 in U.S. Pat. No. 5,829,342) formed therein which receive the toothbrush handle 22. The longitudinal curved depressions 29 are wide and deep enough to comfortably hold a handle 22 therein while not being too wide and deep so as to allow too much movement of the handle 22. Alternatively the depressions 29 may have other shapes, such as being polygonal (e. g. rectangular) in cross-section, and may have friction-enhancing material, such as rubber, placed therein.

[0021] As seen in the drawings the posts 16, 17 have a shape roughly simulating that of a human's tooth, particularly a molar, but that is simply an aesthetic design feature, not a functional one. The posts 16, 17, or like supporting structures, can have almost any desired shape as long as they properly perform their function of supporting a toothbrush 12 so that liquid can drain from the bristles 26.

[0022] The holder 10 can be formed of plastic, such as ABS or high density polyethylene plastic or other plastic having properties comparable to ABS or HDPE, although other materials may be used as long as they wear well in a bathroom environment. The entire holder 10 can be formed in one piece (e. g. by injection molding) or the base 14 and the posts 16, 17 can be discrete pieces and can be assembled and held together by adhesive or mechanical fasteners (such as screws extending through the bottom of the base 14 into the bottoms of the posts 16, 17).

[0023] As seen in FIGS. 1 & 2 the left holder 10 is in combination with a toothbrush 12 having a handle 22 and a head 24 with bristles 26. As also seen therein the base 14 dimensions are such that when the toothbrush handle 22 engages both the top surfaces 18, 19 the toothbrush head 24 and bristles 26 do not overlie the base 14, and the head 24 is closer to the first top surface 18 than the second top surface 19.

[0024] Non-limiting exemplary configurations and dimensions of the base 14 are a rectangle with a width (if only one set of posts 16, 17 is provided) of about 35-45 mm, a length of about 55-65 mm, a height of about 3-15 mm, and with the distance from the end of the first post 16 to the front edge 31 of the base 14 of less than about 10-20 mm. The heights of the posts 16, 17 are preferably about 25-40 mm with the height of the post 17 at least about 4-10 mm higher than the height of the post 16. The distance between the posts 16, 17 may be about 30-45 mm.

[0025] As also seen in FIGS. 1, 2 & 5 the toothbrush-holder combination 10/12 is in further combination with a conventional bathroom sink 33 or the like having a ledge 34 defining the top of a sink bowl 36. The base 14 and toothbrush 12 are positioned adjacent the bowl 36 so that the toothbrush head 24 and bristles 26 extend past the ledge 34 and overlie the sink bowl 36. In this way, any fluid dripping from the toothbrush head 24 and/or bristles 26 drips directly into the bowl 36. In the holder-toothbrush combination 10/12 as seen in FIGS. 1 & 2 preferably the toothbrush handle 22 is mounted on the post top surfaces 18, 19, so that the bristles 26 point downwardly or sideways above the bowl 36, and the depressions 29 accommodate that.

[0026] In a method of drying the bristles of a toothbrush after a human uses the toothbrush 12 to brush her/his teeth he/she positions the holder 10 so that the front edge 31 of the base 14 is adjacent the ledge 34 of the sink bowl 36 (best seen in FIG. 2). After the bristles 26 are rinsed off using water from a faucet of the sink 33, the user places the toothbrush handle 22 on the post top surfaces 18, 19, as seen in FIGS. 1 & 2, so that the bristles 26 do not touch any object, are enveloped by ambient air for easy drying, and overlie the bowl 36 so that any water with or without contaminants (such as residual toothpaste and/or spittle) falls directly into the bowl 36 so that it is easily disposed of down the sink 33 drain whenever the sink 33 faucet is next operated. The method preferably contemplates the bristles 26 being lower than the end 27 of the handle most remote from the bristles 26, most desirably at a cant angle α of between about 4-10° so that the action of gravity facilitates movement of liquid from the bristles 26, with the bristles 26 pointing downwardly or substantially horizontally as seen in FIGS. 1 & 2.

[0027] As seen in the modification of the holder 10′ illustrated in FIG. 5 a front lip 40 may be provided extending downwardly from the front edge 31 of the base 14 adjacent the first post 16, which lip 40 facilitates positioning of the base 14′ at the sink ledge 34, the lip 40 engaging the surface of the sink 33 at the ledge 34. As also seen in this embodiment the holder 10′ has third and fourth posts 16′ (not actually visible, although its top surface 18′ is, in FIG. 5 because it is blocked by rear post 17′), 17′ which have the same relationships as the posts 16, 17, to mount a second conventional toothbrush 12 on the holder 10′. Any number of posts like 16, 17 can be mounted on the base 14 to accommodate a plurality of toothbrushes.

[0028] As also seen in FIGS. 3 & 4, one or more conventional suction cups 42 may be provided attached to the bottom 44 of the base 14 to securely, but readily removably, hold the base 14 in the desired position illustrated in FIGS. 1 & 2. Alternatively the bottom 44 of the base 14 may be flat and continuous or, as illustrated in FIG. 6, the bottom 44 may be recessed as indicated by reference numeral 50. When the bottom 44 has a recess 50 it minimizes the chance of water pooling and/or slippage of the base 14 on the area of the sink 33 adjacent the bowl 36.

[0029] While the invention has been herein shown and described in what is presently considered to be the most practical and preferred embodiment thereof it is to be understood that the invention is to be accorded the broadest interpretation of the appended claims to cover all equivalent devices and procedures, limited only by the prior art.
