7 Claims.

This invention relates to an improved teeth cleaning unit and' more particularly to a teeth cleaning assembly wherein the toothbrush and all accessories necessary for the proper care of teeth are assembledV together in a compact and attractive unit which mayv be conveniently carried in the pocket or purse.

Proper care of the teeth requires daily brushing and cleaning of the teeth which should be done after each meal. Such preferential care cannot be given to the teeth by most individuals since the necessary implements, such as the toothbrush and accessories used by such individual, are not ordinarily carried by the individual or otherwise are noti conveniently available or'accessible throughout the day.

It is the purpose of this invention to provide a teeth cleaningr assembly which presents in one compact, convenientv andV attractive unit, a toothbrush with the necessary complement of dentifrice contained in a dispenser sanitarily housed within a sealed and dustproof compartment in the handle section of the unit. The handle section is alsol provided with a dental floss compartment from whichA dentaliloss may be conveniently dispensed. A tubular' cover section, detachablysecuredy to one endy of. the handle section, provides a sanitary and dustproof compartment for housing and" containing' the brush bristles. with a compartment wherein moisture absorbent and disinfectant material may be contained which serves toextract the moisture carried on the used brushv and maintain the bristles at allY times in thoroughly dis-infected condition. The unit, including the toothbrush andy teeth cleaningV accessories, isv assembledin a compact and sturdy container of such size and form that it may conveniently be carried in the pocket or purse at all times. The unitV can be molded into various attractive forms from available plastic materials, and is so constructed that the bristles are fully protected from dirt, contamination and damage, and maintained at all times' in thoroughly sanitary condition. The teeth cleaning unit assembled in accordance with this invention encourages and makes convenient` the proper cleaning and care of the teeth.

In order that a clearer understandingv ofA this invention may be had, reference is made to the accompanying drawings i-n which:

Fig. 1 is a longitudinal cross sectional view of all the variousy parts `which comprise the improvedl teeth cleaning unitl arranged in exploded view.

The cover section may also be provided Fig. 2 is a longitudinal cross sectional View of the teeth cleaning unit with all parts thereof in assembled position.

Fig. 3 is an end view of the fully assembled unit as the same appears when viewed along line 3 3 of Fig. 2; and

Fig. 4 is a perspective view of the fully assembled unit showing certain parts broken away to reveal certain structural details thereof.

Similar reference characters refer to similar parts throughout the several views of the drawing and specication.

The improved teeth cleaning unit made in accordance with this invention comprises a brush section I permanently xe-d or detachably secured to one end of a hollow handle section 2. A hcliow cover section 3 contains a brush cornpartment a designed to receive and inclose the brush section l. The lower end of the cover section 3 is detachably secured to the handle section at a point adjacent the base of the brush section. The hollow handle section 2 contains a compartment b designed to contain a dentifrice dispenser 4 which. telescopes into the hollow handle section 2.V The lower end of the dentilrice dispenser is provided with a head portion 5 designed to be detachably secured to the end of the hollow handle section `2 and provides a closure therefor. The head portion 5 of the dentifrice dispenser has a hollow interior providing a compartment c for dental oss, The head portion 5 is provided with a cap closure t for containing the dental floss f within the compartment c. The upper end of the removable brush I containing section 3 is closed by a dome shaped cap 'l having a compartment d designed to contain an agent s for drying and sterilizing the brush bristles when contained in the cover section 3.

Referring more particularly to Figs. 1 and 2, the brush section I comprises a stem portion Hl. formed of a suitable plastic tov which two or more rowsof brush bristles Il are firmly secured. The base end o the stem portion lll is provided with a plug portion l2 designed to` snugly t into onev end of the tubular handleA section 2. The plug portion l2 may be provided with external threads. lf3y which thread into corresponding` internal threads. i4 provided at one` end ofI the hollow handle section 2. The brush section l' can thus be removed when worn and' a new brush. section substituted. The stem I0' is provided with an attractively shaped boss portion l5 which capsy the, plug portion I2 and provides a shoulder [6i which lits neatly over thev 3 end l'l of the hollow handle section 2. The stem Ill is of suicient length to permit easy cleaning' of the teeth without insertion into the mouth of any appreciable part of the handle section '2.

The hollow closure section 3 comprises a generally tubular body member 2li into which the brush section l is adapted to telescope. The lower end of the body member 20 is provided with internal threads 2l adapted to be screwed into engagement with the external threads 22 provided at the upper end of the handle section 2. The tubular body member 20 is of sulicient length and interior diameter to snugly receive the brush bristles Il, the stem portion lll and the boss portion l oi the brush section l. The opposite upper end of the body member 20 is closed by the dome shaped closure cap 'l having a hollow dome shaped body portion 25 and a depending ilange 26 adapted to be inserted into the upper end of the tubular body 2i] of the brush containing body member 25. The hollow body portion 25 provides a compartment d adapted to contain a drying and disinfectant agent s. The lower end of the dome shaped body portion 25 is closed by detachable closure plate 21 having a peripheral shoulder 2B which seats against an internal shoulder 28 within the flange portion 26, the closure plate 2l being frictionally re tained in position by the surrounding depending flange 26. The closure plate 2l may be provided with a series of holes or perforations 29 providing communicating passageways between the drying and disinfectant compartment d and the brush containing compartment a. The flange portion 26 may be externally threaded as at 30 to match with internal threads 3l provided at the upper end of the brush containing body member 2B. Thus the dome shaped closure cap l may be detached and the drying and disinfectant agent s contained in the compartment d removed and replenished by simply removing and replacing the closure plate 21.

As shown in Figs. 1, 2 and 3 the dentifrice dispenser d may be of the ejector type adapted to contain the dentifrice in the form of a solid stick p. The lower end of the dentifrice stick p seats in a cup shape receiver 40. A stud 4| projects from the side wall of thecup receiver M) and through a slit d2 extending longitudinally along the side wall of an enclosing tubular protective sleeve 53. The lower end of the tubular sleeve i3 has an enlarged hollow head portion 5 presenting an exterior shoulder Mi designed to abut against the lower end l5 of the hollow tubular handle section 2. A collar portion 46 immediately above the shoulder portion M is designed to snugly t into the lower end of the hollow handle section 2 and may be externally threaded to match the corresponding internal threads 41 formed on the interior of the hollow handle section 2.

The head portion 5 has a hollow interior providing a compartment c adapted to snugly receive a spool of dental floss f. The compartment c is closed at one end by a partition wall 55 and is closed at the other end by a closure cap 6 which has an end wall 50 and a threaded ange 5l designed to be threaded over the threaded end 52 of the head portion 5. The end wall 5l! of the closure cap (i is provided with a suitable pin hole 53 through which the end of the dental oss may be withdrawn, the end wall 5D also being provided with a projection 56 having a sharp edge by means of which predetermined lengths of the dental floss f may be cut off.

When this improved teeth cleaning unit is to be used, the cover section 3 is removed from its telescoped position over the brush section l by unscrewing the lower end of the cover section 3 from the upper end of the handle section 2. The dentifrice dispenser i is removed from the handle section 2 by unscrewing the head portion 5 of the dispenser i from the lower end of the handle section 2. It will be appreciated that the outer surface of section 5 may be suitably knurled as at 55 to provide a firm finger grip. The proper quantity of dentifrice p may be readily deposited on the brush bristles l l by iirst moistening the bristles and stroking the bristles over the projecting end of the dentifrice stick. The cup shape dentifrice receiver lil may be manipulated by the projecting stud 4I so that the upper end of the dentifrice stick p projects a convenient distance from the upper end i8 of the protective sleeve d3. When the proper quantity of the dentifrice has been deposited on the brush bristlesl l i, the stud lll may be returned to its seating position against the closed end 59 of the slot 52, in which position the dentifrice stick p will be fully contained and housed in the protective sleeve #i3 as shown in Fig. 2. The dentifrice dispenser Q- can then be returned to its housed position within the compartment b of the hollow handle section 2 by telescoping the protective sleeve i3 of the dispenser into the compartment l) and then turning the head portion 5 so as to screw the threaded collar portion 46 into the threaded end of the handle section 2. The handle section 2 provides a convenient handle which can be rrnly and conveniently gripped by the hand during brushing of the teeth. When the teeth brushing operation has been completed the closure cover 3 is returned to its telescoped position over the brush section I and screwed or frictionally secured to the upper end of the handle section 2, thereby protecting the brush bristles l l from contamination.

After the brush bristles I l have been used they are wet with moisture and otherwise somewhat v; insanitary. This condition is met by the provision of a drying agent s of high moisture absorption qualities contained within the compartment d of the dome shape closure cap l. Material such as silica jell has been found to be a suitable drying agent. Moisture vapors from the brush bristles pass from the compartment a through the apertures 29 in the closure plate 21 and these vapors are absorbed by the drying agent s contained within the compartment d. If desired, a small pin hole opening 32 may be provided in the upper end of the dome shape body portion 25 of the closure cap l and one or more similar pin shaped openings 33 may be provided in the tubular wall of the body member 2@ of the cover section 3, thereby providing for ventilation of the brush bristles ll. The drying agent s contained in the compartment d also preferably contains a suitable disinfectant designed to give oif disinfectant vapors which pass through the apertures 29 in the closure plate 2l and disinfect the used brush bristles housed in the compartment a. Thus the brush bristles are not only dried and kept dry when not in use, but the bristles are kept in a thoroughly disinfected condition. The construction of the cover section 3 is such that dirt and foreign matter is also prevented from entering the compartment a.

It will be further noted that no moisture carried by the brush bristles housed within the compartment a can reach or enter the fully sealed denti- Samaz frice. compartment b; or the dentaloss-compartment c'. I hedentfrice compartment b provides a sealed. enclosurewhich protects the dentifrice stick p: front contamination and drying. The dentifrice compartment b can be made in gencrous proportions sothat thefdentifrice cartridge p can be made in a` size to contain several days supply of dentifrice The main parts-of the teeth cleaning unit, such asthe, cover section 3; comprising the body member Z, the, dome shape closure member 25 and the perforated plate Z'l can be conveniently and economically formed from suitable plastic resins. IlIhe stemA section. IB and its associated plug portion l2; and. boss portion 15, aswelll as the handle section 2 may also be economicallyv formed. of

plastic, resins. The dentifrice dispenser 4 includingthe cupshape receiver 4Q, the protectivefsleeve ,43, and the head portion 5 thereof, may be econominally molded from pasticresins. The closure cap 6` for the head portion 5 may bemade either of. plastic resins.. or a non-correding metal as4 de- Sired` Thel plastic resins from which the main Darts. of the` unit above described may be formed are, selected both from the standpoint of their formability and moldability as. well as intrinsic beauty.. Numerous, plastic. resins, such as phenolic or urea resins or styrene plastics, are available tol-the, art. The selected resin may be given any desired color tinge. to make the unit either opaque or transparent,` The, parts may be proportioned and streamlined to make the unit attractive` and beautiful without detract-ng from its highly utilitarian and hygienic purposes.

If desired thehandle section 3 may be provided with a suitable pocket clip 60 of any desired shape or form to retain the unit in the wearers pocket. The entire unit need not be larger than a good sized fountain pen and thus can be conveniently carried in the pocket or purse. This hygienic instrument promotes and encourages frequent cleaning-of` the teeth which is a necessary requisite to oral hygiene. All necessary implements for the proper care of the teeth are compacted within this attractive unit and the implements are maintained in fresh and sterilized condition for individual and personal use. The dentifrice compartment b is of generous size and designed to contain a selected dentifrice sufficient for several days use. While the dentifrice dispenser 4 is designed to contain the dentifrice in stick form,

it will be appreciated that the dentifrice compartment b is designed to contain a powdered or paste dentifrice contained within a suitable dispenser. The dentifrice sticks or cartridges may be supplied or sold in dozen lots, packed in a convenient carton, and from which supply the user may periodically replenish the dentifrice to be contained in compartment b.
