Description

Background of the Invention

[0001] 1. Field of the Invention

[0002] The present invention relates to dental hygiene appliances. More particularly, the present invention relates to a compact, disposable finger-mount toothbrush and kit.

[0003] 2. Description of the Related Art

[0004] There are many examples of compact toothbrushes such as travel toothbrushes which have removable handles which may be compactly stored in a kit or the like. The kit may also include a tube of toothpaste. Also known are finger-mount toothbrushes. These brushes are of two general types. One type has a brush on the end of a flexible finger cover or glove. Another type is placed on an index finger in the manner of a finger ring.

[0005] One problem with known designs, particularly those employing a flexible cover for the finger, is keeping the toothbrush bristles from rotating or pulling away from the finger during use. Many of the finger ring type also suffer from instability of placement relative to the finger and teeth during use. The finger ring type does not have a brush cover for single or multiple use and is either not provided in a kit including toothpaste, have a complicated, unreliable design for applying toothpaste to the bristles, or require a separate toothpaste tube either in the kit or separate therefrom.

[0006] It would be desirable to provide a compact, finger-mount toothbrush which may be used once and disposed of or repeatedly used, having a removable and replaceable cover for the bristles, the bristles having a single use portion of toothpaste provided directly on the bristles of the toothbrush. It would also be desirable that the compact toothbrush requires minimum manipulation to use. This would be particularly useful for photography and moving picture studios where a subject or actor may require a quick brushing. In such settings time is valuable and a compact toothbrush ready to use with minimum preparation effort is highly desirable. It would also be desirable that such a toothbrush be reusable, if desired, for the duration of a trip, etc., yet simple, compact, and inherently inexpensive to allow for disposable, one-time use.

[0007] None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. Thus, a compact disposable finger-mount toothbrush solving the aforementioned problems is desired.

Summary of the Invention

[0008] The compact disposable toothbrush of the present invention has a flat, elongate bristle-receiving body having bristles extending outward therefrom in the manner of a traditional toothbrush. A finger clip in the form of an open band ring formed by elongate curved elastic portions extends upward along the length of the bristle receiving body to partially surround the index finger. The elastic action of the curved portions allows for secure mounting to varying sizes of finger.

[0009] The elongate finger clip has side openings in each side to allow side portions of the finger to press into the openings reducing lateral and rotating movement of the brush bristle portion relative to the finger. Inner guide ridges extend along the length of the inner wall of the finger clip, further reducing rotation of the clip relative to the finger.

[0010] A bristle portion cover is provided which fully receives the bristles and conforms to the shape of the bristle-receiving body having an upper lip portion which snaps closed over the body and seals against the body and the lower wall of the finger clip to protect the bristles from contamination during storage, but is easily snapped away for use. The toothbrush and cover may be supplied as a kit with a single portion of toothpaste provided in the cover as snapped closed over the bristle portion of the toothbrush, the bristles extending into the toothpaste, making it compact and extremely easy and quick to use. The kit may be packaged in a sealed wrapper for sanitary distribution and storage.

[0011] These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

Detailed Description of the Preferred Embodiments

[0018] The present invention is a finger-mounted, disposable toothbrush provided in a kit having a toothbrush-conforming brush cover containing toothpaste.

[0019] Referring to FIG. 1, there is shown an environmental perspective view of the finger-mounted toothbrush of the present invention referred to herein by the reference No. 10. Toothbrush 10 has a bristle portion 12 mounted in a bristle receiver 14 which, in turn, is attached to finger clip 16 as shown being worn on index finger F of hand H. The bristles of bristle portion 12 are embedded at their upper ends in bristle receiver 14. Bristle receiver 14 may be attached to finger clip 16 or be of unitary construction with finger clip 16 as desired.

[0020] Referring to FIGS. 2 and 3, there is shown an exploded view of the finger-mounted toothbrush 10 and the brush cover 30 and a side elevation of the closed kit with toothbrush 10 secured in brush cover 30, respectively. Toothbrush 10 has bristle portion 12 mounted in a flat bristle receiver 14 connected with finger clip 16 as above. Finger clip 16 has curved elastic portions 20 forming a two-part open band ring-like structure which closes over a range of sizes of finger F once the elastic portions are spread apart by insertion of the finger therethrough. Finger clip curved elastic portions 20 have apertures 22 in the sides thereof for comfort during use. The apertures 22 also allow the skin of the user's finger to expand through the apertures, contributing to a firm fit.

[0021] Bristle receiver 14 has rounded ends 26 and generally parallel sides having snap ridge receiver grooves 24 therein. Brush cover 30 has an upper rim 32, sidewalls 34 having rounded ends 36, a separating tab 38 extending from one curved end at the lip 32 and opposed snap ridges 40 on the upper inner sides of sidewall 34. Brush cover 30 has a bottom wall 42.

[0022] As seen in FIG. 3, lip 32 of brush cover 30 conforms to and fits over bristle receiver 14 to form a seal therebetween. Snap ridges 40 engage snap ridge receiver grooves 24 to maintain bristle portion 12 within brush cover 30 until use. Toothpaste TP is contained in brush cover 30, covering the lower portion of bristles 12. Tab 38 is located at one end 36 of brush cover 30 at upper lip 32, tab 38 being useful to provide separating force to overcome the holding force of snap ridges 40 to remove cover 30 from toothbrush 10.

[0023] Referring to FIGS. 4 and 5 there is shown a plan view and an end elevation view of the closed toothbrush kit. Finger clip 16 has a lower flat portion 18 connected with bristle receiver 14 and sealing against upper lip 32 of brush cover 30. Tab 38 extends outward from one endwall 36 at upper lip 32 at one end.

[0024] As depicted in FIG. 4, the sidewalls of brush cover 30 may be wider at the proximate end 36 relative to tab 38 extends than at the distal end forming a tapered brush cover 30 fitting a like tapered bristle receiver 14. Finger clip 16 has two spaced lengthwise guide ridges 28 extending upward along the substantial length of finger clip flat portion 18. Each finger clip curved elastic portion 20 also has a lengthwise guide ride 28 extending along the substantial respective lengths thereof at points above and proximate to the upper edges of finger clip apertures 22. Guide ridges 28 help maintain the toothbrush 10 secure on and aligned with finger F (see FIG. 1) during brushing and to avoid rotation on the finger. The curved elastic portions 20 of the finger clip 16 maintain pressure on the inserted finger, keeping guide ridges firmly pressed against the finger, thus avoiding rotation around the finger.

[0025] In use, the user tears away any plastic wrapper and inserts his finger into the finger clip 16 of toothbrush 10. He then pulls on tab 38, snapping away the cover 30. After use the toothbrush and cover may be disposed of or the toothbrush and cover washed and the cover snapped onto the toothbrush to cover the bristles for later use.

[0026] The toothbrush and case of the present invention is preferably made from appropriate plastic materials. The kit may be stored and distributed in a clear, plastic, tear-away wrapper to avoid tampering.

[0027] It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
