Definitions
- the present invention relates generally to a flossing apparatus that facilitates oral hygiene.
- the invention relates to a flossing apparatus with a simplified means for advancing a supply of fresh dental floss to an operable cleaning portion of the apparatus and tensioning same.
- Flossing involves the use of a synthetic string or tape piece, commonly referred to as "floss", to dislodge foreign debris from teeth interstices and other hard to reach areas.
- the technique includes placing a taught piece of floss between adjacent teeth and moving it in an up and down cleaning motion.
- a flossing apparatus having: a body; a floss-receiving chamber at one end of the body; a head at the other end of the body for supporting a length of floss; a rotatable tensioning and locking mechanism adjacent the chamber, the tensioning and locking mechanism having a floss passage, wherein the tensioning and locking mechanism is movable between a first position enabling floss to be withdrawn from the chamber through the floss passage and a second position which simultaneously tensions the length of floss supported by the head and prevents the withdrawal of floss from the chamber through the floss passage; and a circuit extending along the body for receiving a first run of floss and a second run of floss.
- the body is a generally hollow clamshell type structure.
- the floss-receiving chamber may house a spool of floss.
- the spool may be supported by and rotatable with respect to an axle located in the floss-receiving chamber.
- An arm may extend between the head and the rotatable tensioning and locking mechanism.
- the head may have two prongs that are configured to support a length of floss such that the floss extends between the two prongs.
- the tensioning and locking mechanism may have a spindle through which the floss passage extends.
- the spindle may be received by and rotatable with respect to a sleeve that forms part of the body.
- the spindle may be tapered and a tapered aperture may extend through the sleeve.
- a retaining leg may extend from the body, the retaining leg being adapted to retain the spindle within the sleeve.
- the retaining leg may bias the spindle towards the sleeve.
- the retaining leg may be in the form of a diaphragm.
- a lever may extend from the spindle, the lever being operable to rotate the spindle between the first position and the second position.
- the lever may be located adjacent to the floss-receiving chamber so that a user can operate the lever while holding the apparatus by the floss-receiving chamber.
- the circuit may include a floss receiving channel extending along the body.
- the circuit may include an access slot for receiving the second run of floss and allowing the second run to enter the channel.
- the circuit may include an aperture for receiving the second run of floss and allowing the second run to enter the channel.
- locating means for optimal placement and manoeuvrability of the apparatus relative to a user's mouth during use.
- An appropriate locating means is configured and arranged to compliment the contours of the operator's face.
- the apparatus be used by a single person. It is also intended that the apparatus be thrown away once the floss supply has been exhausted, though it would be relatively simple to exchange the floss in the floss-receiving chamber and rewire the floss circuit if the apparatus were to be reused. It is envisaged that the apparatus would optimally be available in various sizes or designs to suit various categories of operator (e.g. a child, teenager or adult) and flossing requirements.

- An access slot 23 extends across a sidewall 25 of the arm 22.
- the access slot 23 includes a curved portion 24 which is located behind a portion of the sidewall 25.
- a groove 26 extends along edge 21 from the sleeve 15 to the curved portion 24 of the access slot 23.
- the head 14 extends from the arm 22.
- the head 14 is configured to support a length of floss.
- the head 14 has a generally U- shaped configuration and is aligned with the arm 22.
- the head 14 includes a first prong 27 which is inwardly spaced from a second prong 28.
- a free end 76 of the first prong 27 includes a groove 29 while a free end 77 of the second prong 28 includes a groove 30.
- a groove 31 extends along edge 21 from the access slot 23 to the free end 77 of prong 28.
- Grooves 26 and 31 form a floss-receiving channel.
- the circuit which extends along the body 11 for receiving a first run of floss and a second run of floss includes the floss-receiving channel, access slot 23 and grooves 29, 30.
- the body 11 also includes a locating means in the form of a U- shaped cavity 32 which is located inwardly of the head 14.
- the locating means enables the apparatus 10 to be appropriately positioned relative to the user's mouth during use.
- Floss can be trained relative to the apparatus 10 in a first manner or a second manner.
- floss from the floss-receiving chamber 12 is fed towards the tensioning and locking mechanism 13.
- the spindle 17 is rotated to the first position to allow the floss to extend through the groove 58.
- the floss is received by the floss-receiving channel formed by grooves 26 and 31.
- the floss is extended and received by grooves 30 and 29 such that a length of floss extends between and is supported by the first prong 27 and the second prong 28.
- the floss is then received by the access slot 23 so that the floss rests on the curved portion 24.
- the floss is then extended along groove 26 towards the tensioning and locking mechanism 13.
- the floss is then inserted back through the groove 58 in the spindle 17.
- floss from the floss-receiving chamber 12 is fed towards the tensioning and locking mechanism 13.
- the spindle 17 is rotated to the first position to allow the floss to extend through the groove 58.
- the floss is received by groove 26 and access slot 23 so that the floss rests on the curved portion 24.
- the floss is then extended and received by grooves 29 and 30 such that a length of floss extends between and is supported by the first prong 27 and the second prong 28.
- the floss is then extended and received by the floss-receiving channel formed by grooves 31 and 26.
- the floss is then inserted back through the groove 58 in the spindle 17.
- the run of floss extending from the locking and tensioning mechanism 13, along the floss-receiving channel formed by grooves 26 and 31 and between the first prong 27 and the second prong 28 is a first run of floss.
- the run of floss extending from the first prong 27 and through the access slot 23 to the tensioning and locking mechanism 13 is a second run of floss.
- Rotating the spindle 17 to the second position has the effect of simultaneously tensioning the length of floss supported by the head 14 and locking the floss in the tensioned state.
- Tensioning the length of floss supported by the head 14 includes tensioning the length of floss which extends between the first prong 27 and the second prong 28. Locking the floss in the tensioned state prevents further withdrawal of floss from the floss- receiving chamber 12 through the groove 58 of the spindle 17.
- a user can then commence cleaning their teeth interstices with the tensioned length of floss 71.
- the spindle 17 is maintained in the second position so that the floss supported by the head 14 remains tensioned and locked. This is achieved with minimal effort as the user simply adjusts their grip on the handle (i.e. the floss-receiving chamber 12) to encompass the lever 60.
- the length of floss which extends between the first prong 27 and the second prong 28 can be replaced with a fresh length of floss. This is accomplished by firstly rotating the spindle 17 to the first position so that the floss can be advanced through the circuit until a fresh length of floss is positioned between the first prong 27 and the second prong 28. Advancement of the floss through the circuit can be accomplished by pulling on a free end of the floss. The spindle 17 is then rotated to the second position.

- various different guides could be utilised to delineate the circuit. For example, closed slots could be used in place of grooves.
- Various structural modifications could be applied to the floss passage if it were considered necessary to keep the lengths of fresh floss and spent floss separate from each other. For example, vertically spaced entries and exits could be provided for the lengths of fresh floss and spent floss, a partition in the groove separating the strands, or separate guides therein.
