Abstract
A dental flosser including a plastic handle having proximal and distal ends, a flosser head at the distal end of the handle, and two spaced apart arms extending from the flosser head. Two distal end portions extend from the arms and secure a strand of floss. The distal end portions may be wider than the respective arms to increase the force required to pull the floss through the distal end portions. The distal end portions may intersect and extend through an interior and exterior plane defined by the interior and exterior surfaces of the arms.
Claims7
A dental flosser comprising:
- a plastic handle having two ends;
- a flosser head at one of the ends of the handle;
- the flosser head including a base part, two spaced apart arms, and a strand of floss molded to the arms, the first arm having a first proximal portion extending from the base and a first distal end portion extending from the first proximal portion, the second arm having a second proximal portion extending from the base and second distal end portion extending from the second proximal portion, the first and second arms and the first and second distal end portions each defining a width generally parallel to the strand of floss, wherein the distal end portions have a greater width than their respective proximal portions, the wider distal end portions increasing the force required to detach the floss from the arms, wherein the lengths and widths of the proximal portions have a predetermined relationship with respect to the lengths and widths of the respective distal end portions in order to decrease bulkiness and material usage while maintaining strength, wherein the first and second distal end portions each define a first length and a first width, and the first and second proximal portions each define a second length and a second width, wherein the first length is between 0.13 inches and 0.23 inches and the first width is between 0.23 inches and 0.33 inches, and wherein the second length is between 0.37 inches and 0.47 inches and the second width is between 0.09 inches and 0.19 inches.
