Abstract

The invention comprises in combination a system of oral hygiene and personal care apparatus with interchangeable and replaceable elements to facilitate oral hygiene needs such as flossing, brushing and gum stimulation, and personal care needs such as shaving, massaging and manicuring. The preferred embodiment comprises a handle having a receiver slot for mounting and securely retaining the self-locking mounting stem of a demountable tool attachment, and a plurality of demountable and interchangeable tool attachments. The handle may enclose a battery-powered electric motor to impart vibrating motion. The preferred tool attachment is a floss cartridge holder designed to retain a disposable floss cartridge having a short strand of dental floss held between two legs of a U-shaped yoke. The disposable floss cartridge has an integral locking mechanism which allows it to be locked into the holder for each use, and afterwards be unlocked, removed and discarded.

Claims

1. A system of oral hygiene and personal care apparatus with interchangeable and replaceable elements comprising in combination:

a. a floss cartridge holder having;

(i) bifurcated prongs with alignment grooves formed into outermost ends and inside edges of said prongs;

(ii) a tongue slot recessed into an area of juncture between said bifurcated prongs, said tongue slot having an indented interior space;

b. a handle to which is attached said floss cartridge holder;

c. a disposable floss cartridge, replaceable in said floss cartridge holder, comprising;

(i) a yoke with two legs and a short strand of dental floss held taut between the tips of said legs;

(ii) an elongated tongue extending rearwardly at the base of said yoke, said tongue being insertable into said tongue slot of said floss cartridge holder;

(iii) a locking means selected from the group consisting of a raised level and a wedge disposed on a flexible surface of said tongue of said floss cartridge and so positioned thereon as to snap into said indented interior space inside said tongue slot of said floss cartridge holder when said cartridge is inserted into said holder, thereby firmly locking said cartridge into said holder;

(iv) a securing means selected from the group consisting of hooked ends, balls or bevels at the tips of said legs of said floss cartridge, so positioned as to seat into said alignment grooves in said prongs of said floss cartridge holder, thereby securing said legs to said prongs and preventing said legs from flexing inwardly when pressure is applied to said strand of dental floss during usage.

2. The invention of claim 1 wherein said flexible surface of said tongue of said floss cartridge is an integrally formed moveable center tab having a moveable front portion attached at a bottom end of said tongue, whereby depressing the moveable front portion of said tab disengages said locking means disposed thereon from the tongue slot in said floss cartridge holder, thereby allowing said floss cartridge to be removed from said floss cartridge holder.

3. The invention of claim 1 wherein said floss cartridge holder is detachably connected to said handle by means of:

a. a mounting stem which extends rearwardly from the juncture of said bifurcated prongs of said holder;

b. a receiver slot, located in a neck portion of said handle, for receiving and holding said mounting stem.

4. The invention of claim 3 wherein:

a. said mounting stem further includes locking forks having forwardly upper ends and rearwardly lower ends integrally attached at their rearwardly lower ends to said mounting stem, then separated and progressively flairing outwardly from said mounting stem, whereby said locking forks may flexibly deflect as said mounting stem is inserted into said receiver slot in said handle;

b. said receiver slot further includes catches formed on the interior surfaces inside said receiver slot, and so arranged thereon as to engage and retain said locking forks on said mounting stem as said mounting stem is inserted into said receiver slot in said handle;

c. a release spring assembly, located inside said receiver slot, supporting integrally formed release buttons, said release buttons arranged to protrude through holes in the sides of said handle, whereby pressure exerted on said release buttons is transmitted to said mounting stem locking forks, thereby disengaging said locking forks from said catches inside said receiver slot and allowing said mounting stem to then be withdrawn from said receiver slot in said handle.

5. The invention of claim 3 further including a plurality of attachments each having similar mounting stem configurations, thereby allowing said plurality of attachments to be interchangeably connected to said handle.

6. The invention of claim 5 wherein said plurality of attachments comprise a gum stimulator, a tooth brush, an interproximal brush, a massage tip, a manicure tool, and a shaving head for razor blades.

7. The invention of claim 1 further including rotary means contained within said handle for imparting vibration to said handle, said rotary means comprising:

a. an electric motor with a rotatable output shaft to which is offsetly affixed an eccentric weight;

b. battery means as a source of energy to power said electric motor;

c. an electrical switch to control energizing of said electric motor by said battery means, thereby causing said eccentric weight on said output shaft of said electric motor to rotate and cause vibration.

8. The invention of claim 1 wherein said floss cartridge holder is formed as an integral part of said handle, and therefore is fixed and not removeable from said handle.
