Abstract
A disposable dental flosser has a floss release feature that is operated with one hand. A movable section of a flosser provides a clamp that clamps one end of a length of floss. Deforming the movable section opens the clamp to release the end of the length of floss. The release of one end of the floss from the flossing device facilitates the easy removal of the floss from teeth.
Claims
1. A flossing apparatus comprising: a body having an anchor terminal, a sliding terminal, and a tie-off; and a movable section flexibly engaged with said body proximal to said tie-off; and a length of floss fixedly engaged with said anchor terminal following through and slidably engaged with said sliding terminal and removably engaged with said tie-off; wherein flexing said movable section and applying stress to the floss releases said floss from said tie-off, allowing said floss to move through said sliding terminal providing a free end of said length of floss for easy removal from between teeth.
2. The apparatus of claim 1 wherein said movable section includes a protrusion; wherein the user may feel the protrusion to locate the movable section by feel.
3. The apparatus of claim 2 wherein said protrusion is an S-shaped bump co-molded with said body; wherein a user can find the protrusion by feel.
4. The apparatus of claim 2 wherein said tie-off further comprises: an anchor wedge formed by said movable section and said body, and a wrapping channel formed in said body; and a release channel proximal to said anchor wedge; wherein said anchor wedge provides a clamp, and wherein said length of floss is wrapped around said wrapping channel and clamped in said anchor wedge, and deforming said movable section opens said anchor wedge thus releasing said floss into said release channel wherein it then moves through said release channel and through said sliding terminal providing a free end of said length of floss.

DESCRIPTION
[0014] FIG. 1 shows the invention's body 1 and a length of floss 2. The body 1 is a molded plastic part that includes a fixed anchor terminal 4, a sliding terminal 5, a tie-off 6, and a movable section 3 connected to the body 1. An S-shaped bump 13 allow a user to locate the movable section 3 by feel. The S-shaped bump 13 is a thin-walled feature that enables deformation of the movable section 3.
[0015] The length of floss 2 is attached to an anchor terminal 4, then passed through an opening in the floss sliding channel 5, then secured to the body 1 in the tie-off area 6 (FIG. 4). The region between the anchor terminal 4 and the floss sliding terminal 5 forms a flossing region which is common in the art.
[0016] FIG. 2 illustrates the tie-off area 6, shown without the floss. The tie-off area 6 includes a wrapping channel 7, a release channel 8 and an anchor wedge 9.
[0017] The wrapping channel 7 and the release channel 8 are formed with smooth edges and surfaces so that the floss 2 encounters little friction. The anchor wedge 9 has locking ridges 14 and an open bottom that connects to the release channel 8.
[0018] FIG. 3 shows the tie-off area 6 with the floss 2 in place and secured in the anchor wedge 9. The figure illustrates the floss 2 routed from the floss-sliding channel 5 to the wrapping channel 7 and then around the back side of the body 1, passing through the anchor wedge 9 and then around the front side of the body 1, passing through the wrapping channel 7 again, and again behind the body 1 to end in the anchor wedge 9. The loose end of the floss 2 is positioned at the bottom of the stack in the anchor wedge 9 as is typical for this type of anchoring. One skilled in the art understands that some types of floss may require additional turns around the body 1 to secure the floss 2. It is also possible to reduce the number of required turns around the body by applying a bounding agent in the anchor wedge 9. The embodiment allows the floss to be segmented by regions wherein the flossing region can have one type of treatment (for example wax or a cleaning agent) and the tie off region may be untreated or treated with a friction agent.
[0019] In FIG. 4 the release is activated by an index finger 10. With the index finger 10 pressing on the movable section 3, portions of the body 1 are deformed. In addition to depressing the movable section 3, the body 1 must be pushed or pulled to apply stress to the floss 2. The direction arrow 12 shows one example direction in which stress can be applied to the floss 2 by moving the body 1. One skilled in the art understands that various directions may cause the floss to release. Depressing the movable section 3 sufficiently to open the anchor wedge 9 (FIG. 2) releases the floss 2 from the anchor wedge 9 (FIG. 2), enabling the floss to be pulled from the teeth.
[0020] In FIG. 5 the tie-off region 6 is shown with the movable section 3 depressed. (The floss is not shown.) The movable section 3 is depressed enough to open the anchor wedge 9.
[0021] In FIG. 6, the tie-off region 6 is shown in the first stage of the floss-release process. In this first stage the movable section 3 is depressed to cause the anchor wedge 9 to open. With tension applied to the floss 2, the floss 2 is pulled through the open bottom of the anchor wedge 9 into the release channel 8. With continued tension applied, the floss 2 slides through the release channel 8, wrapping channel 7, and the sliding terminal 5 until one end of the floss is freed.
[0022] In FIG. 7 one end of the floss 2 is released to be pulled from between the teeth.
[0023] FIG. 8 shows an iteration of the embodiment depicting a body 21 and a length of floss 22. The body 21 is a molded plastic part that includes a fixed anchor terminal 24, a sliding terminal 25, a tie-off 26, and a movable section 23 connected to the body 21. A C-shaped bump 33 allow a user to locate the movable section 23 by feel.
[0024] These embodiments are intended to define but not limit the invention.
