DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figure 1, an isometric view, 10 generally refers to the toothbrush of the present invention. The handle 16 of the toothbrush is where the toothbrush is gripped. The handle 16 has a hand conforming shape for gripping by a user. The first end of the handle is 40 while the second end of the handle is 42. The handle 16 connects to the neck 38. The handle 16 and neck 38 are preferably of one piece construction. The first end of the neck is 44 and the second end of the neck is 46. Attached to the second end of the neck 46 is the toothbrush head 12 containing bristles 14. The bristles 14 are for cleaning teeth. The first end of the handle 40 is hollow and contains a roll of dental floss 18. The dental floss 18 unrolls and goes through the guide slot ?0 over the ridge 34 and onto the floss cutter ?2 where it is cut into lengths. The guide slot 20 aligns the floss 18 after coming off a roll.
The ridge 34 separates the floss 18 from the handle 16 making it easier to grab. The floss cutter 22 both cuts the floss and keeps the loose end. There is a cover member 31 for covering the dental floss l8 and a flap member 32 for covering the guide slot 20, ridge 34 and floss cutter 22. The flap member 32 is openable with a thumb. The cover member 31 is openable by pulling on the flap member 32. The cover member 31 closes with the retaining member 26 attaching to the guide slot 20. The retaining member 26 only attaches to the top of the guide slot 20 leaving room at the bottom for the floss 18.
The flap member 32 closes with the pair of protrusions 28 that straddle the ridge 34.
On the cover member 31 is the male alignment cylinder 24 that, when the cover member 31 is closed, fits into the female alignment cylinder 36. The male alignment cylinder 24 has a smaller diameter than the female alignment cylinder 36 and snaps into place. The alignment cylinders keep the roll of dental floss 18 centered and unrolling smoothly.
The dental floss 18 is available with only the flap member 32 opened. Only when the dental floss 18 needs changing does the cover member need to be opened. The lid 30 incorporates both the cover member 31 and the flap member 32. The floss 18 fits within the inner cavity 48.
Referring to Figure 2, a side cross-sectional view, the hollow end 40 of the toothbrush 10 includes an inner cavity 48 where the roll of dental floss 18 goes. Inner cavity 48 includes a female alignment cylinder 36 which fits within the cylindrical core 54 of the roll of dental floss 18. The dental floss 18 is wrapped around the cylindrical core 54.
Detail is shown in the cover member 31 and flap member 32 which together comprise a bifolding lid 30. The retaining member 26 and male alignment cylinder 24 (short) are shown in their open positions. The inner cavity 48 can extend well into the toothbrush handle. This side view shows the recessed area 50 of the handle including the floss cutter 22.
Referring to Figure 3, a top view, the cover member 31 and flap member 32 are shown. Attached to the flap member 32 are the pair of protrusions 28; attached to the cover member 31 is the retaining member 26. Recess 50 includes the guide slot 20 for the dental floss 18, and the ridge 34 and the floss cutter 22. Also shown are the lip member 52 and the recessed area of the handle 50.
Figure 4 is a side cross-sectional view the same as Figure 2 except the cover member 31 and flap member 32 are in their closed positions and the male alignment cylinder 24 is inserted into the female alignment cylinder 36. In this position of lid 30, the pal r of protrusions 28 embrace the ridge 3:f to provide a snap attachment of flap member 32 to the recessed area 50.
Referring to Figure S, the doss t 8 is inside the toothbrush inner cavity 48 looking towards the cover member 31. The floss cutter 22 is adapted to cut floss 18, and the pair of protrusions 28 embrace the ridge 34.
Referring to Figure 6, the floss I8 is inside the toothbrush inner cavity 48 and the retaining member 26 tightly fits against the lower wall 51 of recess 50 to secure the lid 30 in its closed position. Retaining member ?6 includes a ridge 53 that frictionally fits within a slot 20 in lower wall 51.
The method of using the toothbrush having a flossing dispenser on the brush handle 16 is as follows. Insert the floss 18 onto a female alignment cylinder 36 in the hollow first end of the handle 40. The floss 18 is threaded through guide slot 20 and then outwardly from the first end of the handle 40. The cover member 31 is closed, but the flap 32 is open.
The floss 18 is pulled out to a length appropriate for flossing. Floss cutter 22 is then used to cut the floss 18 to length.
The floss 18 continues to unroll until all the floss 18 is gone, leaving only the cylindrical core 54. The core 54 is removed by unsnapping cover member 31 and is replaced by a new roll of floss 18 on a new core 54. Cover member 31 is then snapped back in place.
In the drawings and specifications there has been set forth a preferred embodiment of the invention, and although specific terms are employed, their use is in a generic descriptive sense only and not for purposes of limitation. Changes in the form and the proportion of parts as well as in the substitution of equivalents are contemplated as circumstance may suggest or render expedient. For example, the present invention contemplates that the handle can be of various shapes or materials. The handle is preferably plastic or rubber coated plastic, but can also be wood or metal.
The bristles are preferably nylon, but can be made of different materials. These and other variations are well within the spirit or scope of the invention in the following claims.
