Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 61/886,356, filed on Oct. 3, 2013.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to a teeth cleaning device and more specifically relates to a device that can be used to brush and floss teeth.
2. Description of the Related Art
Various types of teeth cleaning devices for tooth brushing and dental flossing have been invented and produced, such as a dental flosser U.S. Pat. No. 8,555,901 and a toothbrush U.S. Patent D687,228. However, most teeth cleaning devices have either only tooth brushing function or only tooth flossing function. This makes thorough teeth cleaning not very convenient. To solve the problem, various inventions have been invented such as U.S. Patent D556,455 and U.S. Pat. No. 5,676,167. However, these inventions have several drawbacks. They either significantly increase manufacturing cost or are not very easy to use. Therefore, there is a need for inventing a new teeth cleaning device that not only integrates both tooth brushing and dental flossing functions into a single device, but also easy to fabricate and to use. The present invention is invented for this reason.

BRIEF SUMMARY OF THE INVENTION

The present invention integrates two functions, tooth brushing and dental flossing, into a single device. It enables a person to brush and floss his/her teeth using a single device. The present invention comprises a handle having two ends, a dental floss support near one end of the handle for holding dental floss for flossing teeth, and bristles near the other end of the handle for brushing teeth. The dental floss support can be removed from the handle and also can be mounted on the handle in various directions for easy flossing all teeth.

DETAILED DESCRIPTION OF THE INVENTION

The present invention comprises a handle having two ends, a dental floss support near one end of the handle for holding dental floss for flossing teeth, and bristles near the other end of the handle for brushing teeth. The dental floss support is removable from the handle and can be secured onto the handle in a parallel position with the handle when not in use. The present invention enables a person to brush and floss his/her teeth using a single device.

Preferred Embodiment 1

FIG. 1 is a perspective view of a preferred embodiment of the present invention. Bristles 20 are located near one end 11 of the handle 10. A dental floss support 30 is located near the other end 12 of the handle 10. The shape of the dental floss support 30 is like a letter U with a recess 32 on each distal end of the support 30. When using the present invention to floss teeth, a person wraps one end of dental floss 100 around an extruded structure 60 on the handle 10, pulls the dental floss 100 across the dental floss support 30 through the recesses 32 s, and then wraps the other end of the dental floss 100 around the extruded structure 60 again to secure the dental floss 100 on the dental floss support 30. After flossing teeth, the person unwraps the dental floss 100 from the extruded structure 60, removes the dental floss support 30 from the handle 10, and places the dental floss support 30 into the recess 50 on the handle 10. FIG. 2 is a perspective view of the present invention when the dental floss support 30 is placed into the recess 50 on the handle 10. With the dental floss support 30 being removed from the handle 10 or placed into the recess 50, a person can use the present invention as a toothbrush to brush his/her teeth.
FIG. 3 is a perspective view of the present invention when the dental floss support 30 is removed from the recess 40. With the dental floss support 30 being removed from the recess 40, a person can also use the present invention as a toothbrush. FIG. 4 is an enlarged perspective view of the end 12 of the handle 10 (FIG. 2). From the figure, it can be seen that the recess 40 used to confine the dental floss support 30 on the handle 10 is a T shaped recess. FIG. 4 also shows details of the extruded structure 60. The extruded structure 60 comprises two parts: a small pole 62 connecting directly to the handle 10 (FIG. 2) and a head 64 on the top of the pole 62. The diameter of the pole 62 is smaller than the diameter of the head 64. The height of the pole 62 is very small, about 1 mm. When mounting a dental floss 100 onto the dental support 30 (FIG. 1), a person rotates one end of the dental floss 100 around the pole 62 several times, pulls the dental floss 100 across the recesses 32 s (FIG. 1), and then tightly rotates the other end of the dental floss 100 around the pole 62 several times again. Since the height of the pole 62 is very small, the dental floss 100 is squeezed into a small space. The friction among the dental floss prevents the dental floss from becoming loose during flossing teeth.
FIG. 5 is a perspective view of the dental floss support 30. The dental floss support 30 is a U-shaped structure with a pentagonal pole 35 and a pentagonal head 36 on the bottom. The pole 35 is directly attached with the bottom surface 34, and the head 36 is on the top of the pole 35. At the distal end of each arm 33, there is a recess 32. To mount the dental floss support 30 on the handle 10 (FIG. 3), all a person needs to do is to push the pentagonal pole 35 and the pentagonal head 36 into the T-shaped recess 40 (FIG. 4). The pentagonal pole and head enable the dental floss support 30 to be mounted on the handle 10 in different directions as shown in FIG. 6. By mounting the dental floss support 30 on the handle 10 in different directions, a person can floss his/her teeth from his/her preferred angles.
The recess 50 shown in FIG. 1, FIG. 3, and FIG. 6 is used to store the dental floss support 30 when it is not in use. The present invention is still functional without the recess 50. This is illustrated in FIG. 7.

Preferred Embodiment 2

FIG. 8 is a perspective view of another preferred embodiment of the present invention. Bristles 20 are located near one end 11 of the handle 10. A dental floss support 30 is located near the other end 12 of the handle 10. The shape of the dental floss support 30 is like a letter U with a recess 32 on each distal end of the U. When using the present invention to floss teeth, a person wraps one end of dental floss 100 around an extruded structure 60 on the handle 10, pulls the dental floss 100 across the dental floss support 30 through the recesses 32 s, and then wraps the other end of the dental floss 100 around the extruded structure 60 again to secure the dental floss 100 on the dental floss support 30. After flossing teeth, the person unwraps the dental floss 100 from the extruded structure 60, removes the dental floss support 30 from the handle 10, and places the dental floss support 30 into the recess 50 on the handle 10 as shown in FIG. 9. FIG. 9 is a perspective view of the present invention when the dental floss support 30 is placed into the recess 50 on the handle 10. With the dental floss support 30 being removed from the handle 10 or placed into the recess 50, a person can use the present invention as a toothbrush to brush his/her teeth.
FIG. 10 is a perspective view of the present invention when the dental floss support 30 is removed from the recess 70. With the dental floss support 30 being removed from the recess 70, a person can also use the present invention as a toothbrush. FIG. 11 is an enlarged perspective view of the end 12 of the handle 10. From the figure, it can be seen that the recess 70 used to confine the dental floss support 30 upright on the handle 10 (FIG. 8) is a pentagonal recess. FIG. 11 also shows details of the extruded structure 60. The extruded structure 60 comprises two parts: a small pole 62 connecting directly to the end 12 of the handle 10 and a head 64 on the top of the pole 62. The diameter of the pole 62 is smaller than the diameter of the head 64. The height of the pole 62 is very small, about 1 mm. When mounting a dental floss 100 onto the dental support 30 (FIG. 8), a person rotates one end of the dental floss 100 around the pole 62 several times (FIG. 11), pulls the dental floss across the recesses 32 s (FIG. 8), and then tightly rotates the other end of the dental floss 100 (FIG. 8) around the pole 62 several times again (FIG. 11). Since the height of the pole 62 is very small, the dental floss 100 is squeezed into a small space. The friction among the dental floss 100 prevents the dental floss 100 from becoming loose during flossing teeth.
FIG. 12 is a perspective view of the dental floss support 30. The dental floss support 30 is a U-shaped structure with a pentagonal pole 38 in contact with the bottom surface 34 of the U shape. At the distal end of each arm 33, there is a recess 32. To mount the dental floss support 30 on the handle 10 (FIG. 10), all a person needs to do is to push the pentagonal pole 38 into the recess 70. The pentagonal recess 70 and the pentagonal pole 38 enable the dental floss support 30 to be mounted on the handle 10 in different directions as shown in FIG. 13. By mounting the dental floss support 30 on the handle 10 in different directions, a person can floss his/her teeth from his/her preferred angles.
The recess 50 shown in FIG. 8, FIG. 10, FIG. 11, and FIG. 13 is used to store the dental floss support 30 when it is not in use. The present invention is still functional without the recess 50. This is illustrated in FIG. 14
The above embodiments are presented for illustrative purposes and are not intended to limit the scope of the present invention. Other modifications can be undertaken by a skilled artisan without departing from the spirit and scope of this invention.
For example, the cross-sections of the recess 40 shown in FIG. 4 and the recess 70 shown in FIG. 11 can be any shape, such as polygon, round, crisscross, etc. The cross-sections of pole 35 shown in FIG. 5 and pole 38 shown in FIG. 12 do not have to be pentagonal. They can be any shape, such as polygon, round, crisscross, etc. The head 36 shown in FIG. 5 does not have to be pentagonal. It can be any shape.
