Definitions
- the present invention relates to a combined dispenser for toothpaste or other dentrifice and toothbrush device.
- Prior G.B. Specification No. 133 6755 discloses a toothbrush wherein toothpaste is contained within the handle and discharged under the influence of a threaded spindle and piston, via holes in the base of a recess, onto bristles of a pivotally mounted toothbrush member when located therein in the inoperative position of the toothbrush.
- the disadvantage of such device resides in the fact that the paste holes in the recess in the handle do not have any special closure means therefor and thus, when the brush is being utilised there is nothing to prevent paste from escaping through the holes nor for the paste from becoming hardenen by exposure to the atmosphere with resultant risk of blockages.
- the toothbrush of the present invention whilst providing the advantageous compact and readily manageable device with the bristles being located in a recess in the handle, also provides for closing of the paste duct means when paste is not being used therethrough by the paste urging means and thus hardening of paste is avoided as is the undesired discharge of paste from the paste reservoir or escape from the recess.
- a combined dispenser for toothpaste or other dentrifice and toothbrush device comprising an elongate container for receiving or containing dentrifice and forming a handle member; a toothbrush member hingeably or pivotally connected or connectable to said handle member and supporting bristles; ducting means leading or capable of leading from the handle member to the bristles of said brush member; and means for enabling paste to be urged through said ducting means to said bristles, said toothbrush member being adapted to be pivotally displaced relative to said handle so that in an inoperative position the brush member is juxtaposed or lies along or adjacent said handle member with the bristles of the brush member located within a space or recess within the handle member or a displaceable paste dispensing member adjacent thereto, while in the operative position the brush member extends from the end of said handle and away therefrom to permit teeth cleaning operations to be effected, characterised in that:-
- a paste duct extending from the container in the form of an angled tubular duct be pivotally connected coaxially with a tubular duct of the paste duct of the brush member to permit desired pivotal connection between the components.
- a paste container 10 and brush member 11 are interconnected by a hinge member 12 similar in construction as the member 27 (and surrounding housing) as the corresponding components (27) of Figs. 5, 5a, 5b and 6 except that member 12 does not have a paste passage therethrough.
- the brush member is displaceable out of the secured operative position shown in full lines in Fig. 1 into an inoperative position as shown in broken line with the bristles 13 resting in a recess 14.
- Paste may be urged onto the bristles 13' via duct 15 in the recess by turning knob 16 of a paste displacing means comprising a screw means 17 rotatable within the container 10 by knob 16.
- Rotation of screw 17 causes a piston or pressure member 18 to be displaced within container 10 to cause paste contained therein to be urged out of duct 15 onto the bristles 13.
- Closure of the paste duct in the example given is effected by the means shown in Fig. 17 although any suitable alternative arrangement may be used.
- the device of Figs. 2, 3 and 4 comprises a toothbrush container 10 and brush member 11 pivotally interconnected at 19 (not shown in detail) with the container 10 and brush member 11 having oppositely facing and similarly shaped, T-shaped recesses 20.
- Paste ducting means open in apertures 21 in the central T-shaped portion of the cross-piece of recesses 20 and are disposed so that in the open position with the brush member 11 pivoted so as to extend from the end of the container 10 the apertures 21 are aligned and interconnected by an apertured, slidable- hinge-valve member 22 shown in position in Fig. 2.
- This slidable member 22 includes two wings or plates having apertures 22' therein and which are slidable in the recesses 20 of the container 10 and brush member 11 such that in the position of use (Fig. 4) with the apertures 21 aligned together, the apertures 22' in the wings of the hinges are also aligned with the apertures 21 so as to permit the paste to be urged therethrough by means (not shown in detail) which may be similar to those described in Fig. 1 as required and supplied via ducting means to the bristles of the brush member as hereinbefore described.
- a rotary member 23 which is rotatable to move the paste displacing means.
- the rotary member 23 is rectangular and has a recess 24 into which the bristles of the brush may be located in the folded position.
- a pin 25 is provided in the recess and located in a paste duct aperture 26 which enables paste to be urged onto the bristles 13. This pin 25 stops aperture 26 and prevents discharge and hardening of the paste therein.
- the hinge closure member 22 will be restricted in its movement so as not to fall out of the recesses 20 and operates such that as the brush member 11 is pivoted into the folded position, the movement of said brush member 11 relative to the container 10 causes the apertures 22' to be moved out of alignment with apertures 21 thereby closing the paste ducting passage.
- Such valve member movement may be facilitated or increased by suitable shaping or projection means on the casings of the components or by the actual disposition of the main hinge and the pivoting thereof.
- a double swivel or cylinder joint 27 having double pivot portions 27' and 27" respectively located by axial sliding and snap-fit in corresponding recess 28 in brush member 11 and in recess 29 in container 10.
- the recesses 28 and 29 each have a cut-out portion 30 to permit additional relative movement of the components during the pivoting to achieve the desired folded position and opened position.
- the joint member 27 has a central passage 31 for flow of paste urged by suitable means (not shown although similar to the previous embodiments) and in the open position of the device such passage 31 aligns with ducting means 32 and 33 in the container 10 and brush member 11 respectively.
- suitable means not shown although similar to the previous embodiments
- the bristles 13 located in recess 24 in the end member of container 10 and the aperture 26 in the bristles 13 is closed by a spike or like pointed closure member 25 in the bottom of recess 24.
- the joint member 27 assumes a substantially vertical transverse position as shown in broken line so that the apertures 31 are no longer aligned with apertures 32 and 33 and thus the ends of the paste passage portions of the device are closed.
- Fig. 6 is an enlarged fragmentary section showing the pivot connection in the operative position and showing a groove 10' and projection 11' in the container 10 and brush member 11 which are so shaped and dimensioned as to provide a snap-fit arrangement so as to hold the brush in the operative position during use and then permit disengagement and subsequent pivoting to the inoperative position.
- the container 70 has an elongate passage 36, extending along a side thereof and in which a similarly or correspondingly cross sectioned stem of a brush member 37 is retractably slidable into a collapsed position (Fig. 7a) from an extended position of use (Fig. 7).
- This arrangement permits generally linear displacement of the brush member 37 and bristles 13 from the operative position to the inoperative position.
- Paste is dispensed to the brush portion 13 through a duct 38 located adjacent the position of the bristles 13 when the brush member 37 is in the inoperative position, Fig. 7a.
- Paste duct closure means are provided comprising a spring biassed member 82, 83 operating as described hereinafter.
- a closure flap is hingedly located at the end of the container to close the end thereof when the brush member is moved into the inoperative position. Suitable detent and snap-fit arrangements are provided in the stem 37 and surrounding casing to hold the brush member in the operative position.
- the embodiment of the toothbrush illustrated in Figs. 8 and 9 comprises a paste container 42 for containing or receiving toothpaste and also acting as the handle for the toothbrush.
- a rotary threaded spindle or screw member 43 rotatably mounted at both end regions and rotatable by means of an end knob-like member 44 so that a pressure member or piston 45 is displaceable within the hollow space provided in the container 42 so as to thereby enable paste to be displaced therefrom via passage 46.
- the end member 44 also includes a recess 47 in which the bristles 13 of the toothbrush are locatable in the inoperative position of the toothbrush and a closure pin 48 extends from the base thereof for co-operation with the toothbrush outlet duct as will be described hereinafter.
- a pivot connection 49 is provided between the container 42 and brush member 50 bearing bristles 13.
- the member 50 has a paste duct 51 extending therethrough and opening into the region of the bristles 13 by way of an aperture 51'.
- the pivotal hinge connection 49 between the container 42 and the bristle support member 50 is such as to permit paste to be displaced along the duct 46 and 51 to the bristles 13 in the operative position but to permit folding of the brush member 50 against or along the container 42 whilst at the same time closing the toothpaste ducts.
- the pivot comprises an extension on the container 42 comprising a cylindrical member or portion 52 supported in cantilever manner on an end face (in the remote side in the drawing (not shown)) by a part of container 42 with said cylindrical portion 52 being spaced from an arcuate part circle portion 53 of the container 42.
- a passage 54 is provided extending through the portion 52 and is off-centre relative thereto but aligned with passage 46.
- the end of the brush member 50 has an annular ring portion 55 provided thereon pivotally and securely locatable on portion 52 with apertures 55' and 55" formed therein to be alignable in the operative position with passage 54 and passage 46.
- the ring 55 engages around cylindrical member 52 and is held thereon by suitable press fit means (not shown) and the brush member 50 is pivotable relative to the container 42.
- the paste ducts are all aligned so that paste may be urged through the ducts by displacement of member 45 to the bristles 13.
- the brush is retained in this position by press fit groove and socket means as shown.
- the bristle support member 50' lies along the container or handle portion 42 and the bristles 13 are located within the recess 47 with the pin 48 extending into the aperture 51' thereby closing such paste duct.
- the embodiment illustrated in Figs. 10 to 13 comprises a handle and paste container member 56 and a brush member or bristle support member 57 having a paste duct 58 extending therethrough and leading at the free end to an opening in bristles 13.
- the bristle support member 57 is pivotally connected to handle 56.
- the handle 56 has a knob member 59 at one end for rotating a screw member 60 within the handle 56 so as to thereby displace a piston or pressure member 61 within the hollow container or handle 56 to cause paste located therein to be discharged through the paste ducts of the toothbrush and onto the bristles 13. Paste is discharged from the handle 56, through a duct leading through the pivot connection and through duct 58 to the bristles 13.
- the rotary knob member 59 defines a large recess in which the bristle members 13 may be located in the inoperative position of the device. Suitable closure means such as a pin 62 may be provided for the paste aperture in the bristles 13. The pivoting from the operative to inoperative position may be effected simply from the position of Fig.
- the pivot connection between the handle 56 and bristle support member 57 has a displaceable characteristic in that the bristle support member 57 and handle 56 may be separated somewhat relative to each other so that the bristle support member 57 may be moved from the operative position laterally away from the handle 56 and then pivoted to the folded, inoperative position whereupon the two components are then pushed together so that the bristles 13 move into the recess 59' in the knob member 59 whereby pin member 62 located in the recess 59' thus engages with the aperture 26 in the bristles 13 to close the paste duct therein.
- Fig. 13 is a fragmentary detail of the pivotal connection wherein the members are shown separate and wherein an end wall 63 of the paste container portion 56 has an aperture 64 therein for the outlet of paste therefrom when displaced by the pressure means 61.
- the bristle support member 57 has a pivot axle 65 with a duct 65' extending axially therealong and also at right angles thereto. Axel 65 pivots in a passage in the handle 56 and duct 65' communicates with the duct 58 leading to the bristles 13.
- An aperture 65" is provided in the wall of the axle 65 such that when in the operative position the aperture 64 and 65" are aligned to permit paste to be discharged through the ducts to the bristles 13.
- An enlargement 65'" is provided at the end of the axle 65 co-operating with a groove 63' in the handle member such that the two handle and brush members may be displaced transversely relative to their longitudinal axis and relative to each other to permit the desired folding of the bristle support member alongside the handle member 56 and then the moving together of the two members to locate the pin 62 in the aperture 26 of the bristles 13.
- the axial member 65 has two longitudinal ribs 66 diametrically opposite and located in a plane at right angles to the longitudinal axis of the brush member 57.
- the ribs 66 co-operate with co-operating grooves 67 formed in the transverse passage in the handle member 56 so as to act to retain such ribs in the grooves. This arrangement permits the toothbrush to be retained in its operative position until the ribs are displaced out of the grooves and displaced through approximately 180° whereupon the ribs 66 relocate in the grooves 67 and the members are then held securely in the inoperative position.
- a non-pivoting toothbrush arrangement wherein there is provided an axially displaceable knob or rotary member 68 biassed by spring means 69 outwardly of toothbrush container 70 having bristle support 71 extending therefrom and carrying bristles 13.
- a piston or pressure member 72 of generally rectangular form with inclined faces 78 is carried by a rod 79 on which there are located a plurality of conical members 80 arranged to point in the same direction and resilient so as to be displaceable through a correspondingly shaped conical aperture 77' in member 72.
- the portions 80 are shaped so as to be capable of being drawn through aperture 77' whereupon they are reduced or compressed in diameter somewhat and on passing therethrough, from right to left in Figs. 14 and 15, they then expand and act against the flat surface of member 72 acting to be pushed thereagainst and not be displaceable through the aperture 77'.
- a plurality of parallel, step-like teeth 81 forming a ratchet-like arrangement co- operably engageable with the sloping surfaces 78 of member 72 such that when the member 72 is urged by portion 80 acting against the left-hand face thereof, as shown in the drawings, member 72 may be displaced step-like along from groove to groove between the teeth 81 -the resilience of the casing and teeth and the portions 80 permitting this action.
- This opposite ratchet-like arrangement enables the member 72 to be stepped along the teeth of ratchet 81 by depressing knob 68.
- the spring 69 causes conical portions 80 to be drawn stepwise through the member 72 whilst the non-sloping surfaces of the teeth 81 prevent movement of the member 72 towards knob 68.
- the next depressions or axial movements of the knob 68 into the container 70 causes a stepwise movement of the member 72 within the paste container 70 thereby causing stepwise urging of the paste through the paste duct 71' and to the bristles 13.
- Such step-like paste dispensing mechanism may be provided in the earlier arrangements in place of the threaded screw member as would be readily apparent to persons skilled in the art without undue major modification - various possible arrangements also exist for modifying the paste duct closure means.
- a paste duct closure means is shown adjacent the aperture leading to the bristles 13 and comprises a displaceable cylinder or like member 82 spring biassed by spring 83 into a closed position sealing off the aperture 84 leading to the bristles 13.
- the paste is urged under pressure through duct 71 and such pressure displaces the closure member 82 against the action of the spring thereby opening the paste duct to the aperture 84 and the bristles 13 and permitting paste to be urged to the bristles.
- the spring 83 causes the member 82 to close the paste duct. This arrangement might be provided for the earlier disclosed embodiments without undue modification and such is shown in greater detail in Fig. 16.
- Fig. 17 an arrangement is provided which is particularly suitable for use with a rotary, axially displaceable threaded member as an extension thereof so that rotation of the extension 85 causes circular closure member 86 to move through 180° thereby opening the paste duct 84 for a short while permitting paste to be urged to the bristles 13.
- Fig. 18 shows an alternative arrangement of paste duct closure means wherein a polythene or other plastics material flexible finger 87 extends from the aperture in the paste duct and is closed by the pressure of the surrounding bristles 13 although does open under paste pressure to permit paste to be discharged into an upper region at the top of the finger 87 in the upper region of the bristles 13.
- Fig. 19 shows a still further alternative arrangement of the paste duct closure means comprising a number of ribs 88 joined together with a flexible film or the like material 90 and may be clipped onto the paste duct outlet aperture 91 such that the member by virtue of the resilient film 90 closes together to form a stack-like arrangement as shown in Fig. 19a through which paste may be urged upon action on the paste displacing means but which close together to seal off the aperture when the paste pressure drops.
- bristles 13 may be arranged in sloping manner or groups thereof in sloping manner about the paste duct aperture so as to form a conical or surrounding abutting arrangement through which paste may be urged under pressure but which act to close the paste duct when the pressure is relieved.

Abstract
Description
- The present invention relates to a combined dispenser for toothpaste or other dentrifice and toothbrush device.
- Various prior specifications have been revealed relating to similar subject matter although none of such prior specifications have advantageous dentrifice ducting means.
- Prior G.B. Specification No. 133 6755 discloses a toothbrush wherein toothpaste is contained within the handle and discharged under the influence of a threaded spindle and piston, via holes in the base of a recess, onto bristles of a pivotally mounted toothbrush member when located therein in the inoperative position of the toothbrush. The disadvantage of such device resides in the fact that the paste holes in the recess in the handle do not have any special closure means therefor and thus, when the brush is being utilised there is nothing to prevent paste from escaping through the holes nor for the paste from becoming hardenen by exposure to the atmosphere with resultant risk of blockages. Additionally, when the toothbrush is in the inoperative, carrying position with the bristles in the recess, paste may still pass from said holes onto the bristles and paste may also become hard in such region which is disadvantageous since it leads to clogging thereof and also can prove unhygienic. The bottom of the recess may become covered with paste which might even escape from the handle. In contrast to this the toothbrush of the present invention whilst providing the advantageous compact and readily manageable device with the bristles being located in a recess in the handle, also provides for closing of the paste duct means when paste is not being used therethrough by the paste urging means and thus hardening of paste is avoided as is the undesired discharge of paste from the paste reservoir or escape from the recess.
- It is an object of the invention to overcome disadvantages of prior devices and provide the advantageous feature described herein.
- According to the present invention there is provided a combined dispenser for toothpaste or other dentrifice and toothbrush device comprising an elongate container for receiving or containing dentrifice and forming a handle member; a toothbrush member hingeably or pivotally connected or connectable to said handle member and supporting bristles; ducting means leading or capable of leading from the handle member to the bristles of said brush member; and means for enabling paste to be urged through said ducting means to said bristles, said toothbrush member being adapted to be pivotally displaced relative to said handle so that in an inoperative position the brush member is juxtaposed or lies along or adjacent said handle member with the bristles of the brush member located within a space or recess within the handle member or a displaceable paste dispensing member adjacent thereto, while in the operative position the brush member extends from the end of said handle and away therefrom to permit teeth cleaning operations to be effected, characterised in that:-
- (a) the ducting means are closed to the atmosphere except at the outlet end whereat dentrifice is discharged onto the bristles;
- (b) at said outlet end of said ducting means a duct closure means is provided which closure means functions to close said outlet end of the ducting means when dentrifice is not desired to be dispensed to the bristles and which closure means opens or is openable when the means for enabling paste to be urged through the ducting means is operated; and in that
- (c) the ducting means extend from the handle member by way of the toothbrush member to the bristles so as to be pivotally displaceable with the toothbrush member and provide a passage leading to said bristles at least when the toothbrush member is in said operative position; and ducting means having regions leading from the handle member of container and extending through said pivot interconnection means or extending across and adjacent the pivot interconnection means to the bristles of said toothbrush member so that dentrifice may be dispensed from the container through said ducting means onto said bristles when said toothbrush member is in said operative position.
- In one embodiment of the present invention is is proposed that a paste duct extending from the container in the form of an angled tubular duct be pivotally connected coaxially with a tubular duct of the paste duct of the brush member to permit desired pivotal connection between the components.

- Figs. 27 and 28 are schematic views of a further embodiment where the paste container and brush member are hingedly interconnected and the interconnection of the paste ducts effected by a flexible tubular member.
- In the embodiment of Fig. 1, not forming an embodiment of the invention, a
paste container 10 andbrush member 11 are interconnected by ahinge member 12 similar in construction as the member 27 (and surrounding housing) as the corresponding components (27) of Figs. 5, 5a, 5b and 6 except thatmember 12 does not have a paste passage therethrough. The brush member is displaceable out of the secured operative position shown in full lines in Fig. 1 into an inoperative position as shown in broken line with thebristles 13 resting in arecess 14. Paste may be urged onto the bristles 13' viaduct 15 in the recess by turningknob 16 of a paste displacing means comprising a screw means 17 rotatable within thecontainer 10 byknob 16. Rotation ofscrew 17 causes a piston orpressure member 18 to be displaced withincontainer 10 to cause paste contained therein to be urged out ofduct 15 onto thebristles 13. Closure of the paste duct in the example given is effected by the means shown in Fig. 17 although any suitable alternative arrangement may be used. - The device of Figs. 2, 3 and 4 comprises a
toothbrush container 10 andbrush member 11 pivotally interconnected at 19 (not shown in detail) with thecontainer 10 andbrush member 11 having oppositely facing and similarly shaped, T-shaped recesses 20. Paste ducting means open inapertures 21 in the central T-shaped portion of the cross-piece ofrecesses 20 and are disposed so that in the open position with thebrush member 11 pivoted so as to extend from the end of thecontainer 10 theapertures 21 are aligned and interconnected by an apertured, slidable- hinge-valve member 22 shown in position in Fig. 2. Thisslidable member 22 includes two wings or plates having apertures 22' therein and which are slidable in therecesses 20 of thecontainer 10 andbrush member 11 such that in the position of use (Fig. 4) with theapertures 21 aligned together, the apertures 22' in the wings of the hinges are also aligned with theapertures 21 so as to permit the paste to be urged therethrough by means (not shown in detail) which may be similar to those described in Fig. 1 as required and supplied via ducting means to the bristles of the brush member as hereinbefore described. At the end of thecontainer 10 is arotary member 23 which is rotatable to move the paste displacing means. Therotary member 23 is rectangular and has arecess 24 into which the bristles of the brush may be located in the folded position. Apin 25 is provided in the recess and located in apaste duct aperture 26 which enables paste to be urged onto thebristles 13. Thispin 25 stopsaperture 26 and prevents discharge and hardening of the paste therein. Thehinge closure member 22 will be restricted in its movement so as not to fall out of therecesses 20 and operates such that as thebrush member 11 is pivoted into the folded position, the movement of saidbrush member 11 relative to thecontainer 10 causes the apertures 22' to be moved out of alignment withapertures 21 thereby closing the paste ducting passage. Such valve member movement may be facilitated or increased by suitable shaping or projection means on the casings of the components or by the actual disposition of the main hinge and the pivoting thereof. - In the arrangement of Fig. 4, as amplified by Figs. 5a, and 5b and Fig. 6, the supply of paste through the hinge or pivot region between the
container 10 andbrush member 11 is achieved via a double swivel orcylinder joint 27 havingdouble pivot portions 27' and 27" respectively located by axial sliding and snap-fit incorresponding recess 28 inbrush member 11 and inrecess 29 incontainer 10. Therecesses portion 30 to permit additional relative movement of the components during the pivoting to achieve the desired folded position and opened position. Thejoint member 27 has acentral passage 31 for flow of paste urged by suitable means (not shown although similar to the previous embodiments) and in the open position of the devicesuch passage 31 aligns withducting means container 10 andbrush member 11 respectively. When the device is folded into the inoperative position, thebristles 13 located inrecess 24 in the end member ofcontainer 10 and theaperture 26 in thebristles 13 is closed by a spike or likepointed closure member 25 in the bottom ofrecess 24. In such a position thejoint member 27 assumes a substantially vertical transverse position as shown in broken line so that theapertures 31 are no longer aligned withapertures - Fig. 6 is an enlarged fragmentary section showing the pivot connection in the operative position and showing a groove 10' and projection 11' in the
container 10 andbrush member 11 which are so shaped and dimensioned as to provide a snap-fit arrangement so as to hold the brush in the operative position during use and then permit disengagement and subsequent pivoting to the inoperative position. - In Fig. 7 (not forming an embodiment of the invention) there is illustrated a
paste container 70 with pressurization means and dispensing means for the paste as described in detail with respect to Figs. 14, 15 and Fig. 16 with respect to the paste duct closure means. Thecontainer 70 has anelongate passage 36, extending along a side thereof and in which a similarly or correspondingly cross sectioned stem of abrush member 37 is retractably slidable into a collapsed position (Fig. 7a) from an extended position of use (Fig. 7). This arrangement permits generally linear displacement of thebrush member 37 andbristles 13 from the operative position to the inoperative position. Paste is dispensed to thebrush portion 13 through aduct 38 located adjacent the position of thebristles 13 when thebrush member 37 is in the inoperative position, Fig. 7a. Paste duct closure means are provided comprising a springbiassed member stem 37 and surrounding casing to hold the brush member in the operative position. - The embodiment of the toothbrush illustrated in Figs. 8 and 9 comprises a
paste container 42 for containing or receiving toothpaste and also acting as the handle for the toothbrush. Within thecontainer 42 there is located a rotary threaded spindle or screwmember 43 rotatably mounted at both end regions and rotatable by means of an end knob-like member 44 so that a pressure member or piston 45 is displaceable within the hollow space provided in thecontainer 42 so as to thereby enable paste to be displaced therefrom viapassage 46. Theend member 44 also includes arecess 47 in which thebristles 13 of the toothbrush are locatable in the inoperative position of the toothbrush and aclosure pin 48 extends from the base thereof for co-operation with the toothbrush outlet duct as will be described hereinafter. - A
pivot connection 49 is provided between thecontainer 42 andbrush member 50 bearing bristles 13. Themember 50 has apaste duct 51 extending therethrough and opening into the region of thebristles 13 by way of an aperture 51'. Thepivotal hinge connection 49 between thecontainer 42 and thebristle support member 50 is such as to permit paste to be displaced along theduct bristles 13 in the operative position but to permit folding of thebrush member 50 against or along thecontainer 42 whilst at the same time closing the toothpaste ducts. The pivot comprises an extension on thecontainer 42 comprising a cylindrical member orportion 52 supported in cantilever manner on an end face (in the remote side in the drawing (not shown)) by a part ofcontainer 42 with saidcylindrical portion 52 being spaced from an arcuatepart circle portion 53 of thecontainer 42. Apassage 54 is provided extending through theportion 52 and is off-centre relative thereto but aligned withpassage 46. The end of thebrush member 50 has anannular ring portion 55 provided thereon pivotally and securely locatable onportion 52 withapertures 55' and 55" formed therein to be alignable in the operative position withpassage 54 andpassage 46. - In the assembled condition the
ring 55 engages aroundcylindrical member 52 and is held thereon by suitable press fit means (not shown) and thebrush member 50 is pivotable relative to thecontainer 42. In the operative position with the bristle support pivoted away from thecontainer 42, the paste ducts are all aligned so that paste may be urged through the ducts by displacement of member 45 to thebristles 13. The brush is retained in this position by press fit groove and socket means as shown. In the folded condition of the toothbrush, the bristle support member 50' lies along the container or handleportion 42 and thebristles 13 are located within therecess 47 with thepin 48 extending into the aperture 51' thereby closing such paste duct. Theapertures 55' and 55" in the inoperative condition are no longer aligned with thepaste ducts ring portion 55. Any similar pivot interconnection, e.g. rounded or ball and socket-like means (possibly with the component parts being reversed in their location on the members) may be provided and appropriate sealing effected. - The embodiment illustrated in Figs. 10 to 13 comprises a handle and
paste container member 56 and a brush member or bristlesupport member 57 having apaste duct 58 extending therethrough and leading at the free end to an opening in bristles 13. Thebristle support member 57 is pivotally connected to handle 56. - The
handle 56 has aknob member 59 at one end for rotating ascrew member 60 within thehandle 56 so as to thereby displace a piston orpressure member 61 within the hollow container or handle 56 to cause paste located therein to be discharged through the paste ducts of the toothbrush and onto thebristles 13. Paste is discharged from thehandle 56, through a duct leading through the pivot connection and throughduct 58 to thebristles 13. Therotary knob member 59 defines a large recess in which thebristle members 13 may be located in the inoperative position of the device. Suitable closure means such as a pin 62 may be provided for the paste aperture in thebristles 13. The pivoting from the operative to inoperative position may be effected simply from the position of Fig. 10 in which case a side ofknob 59 would have a gap (not shown) for the passage of thebristles 13 which may have a gap therein for receiving the closure means 62. However, in the preferred arrangement as shown the pivot connection between thehandle 56 and bristlesupport member 57 has a displaceable characteristic in that thebristle support member 57 and handle 56 may be separated somewhat relative to each other so that thebristle support member 57 may be moved from the operative position laterally away from thehandle 56 and then pivoted to the folded, inoperative position whereupon the two components are then pushed together so that thebristles 13 move into the recess 59' in theknob member 59 whereby pin member 62 located in the recess 59' thus engages with theaperture 26 in thebristles 13 to close the paste duct therein. Fig. 13 is a fragmentary detail of the pivotal connection wherein the members are shown separate and wherein anend wall 63 of thepaste container portion 56 has anaperture 64 therein for the outlet of paste therefrom when displaced by the pressure means 61. Thebristle support member 57 has apivot axle 65 with a duct 65' extending axially therealong and also at right angles thereto.Axel 65 pivots in a passage in thehandle 56 and duct 65' communicates with theduct 58 leading to thebristles 13. Anaperture 65" is provided in the wall of theaxle 65 such that when in the operative position theaperture bristles 13. An enlargement 65'" is provided at the end of theaxle 65 co-operating with a groove 63' in the handle member such that the two handle and brush members may be displaced transversely relative to their longitudinal axis and relative to each other to permit the desired folding of the bristle support member alongside thehandle member 56 and then the moving together of the two members to locate the pin 62 in theaperture 26 of thebristles 13. - The
axial member 65 has twolongitudinal ribs 66 diametrically opposite and located in a plane at right angles to the longitudinal axis of thebrush member 57. Theribs 66 co-operate withco-operating grooves 67 formed in the transverse passage in thehandle member 56 so as to act to retain such ribs in the grooves. This arrangement permits the toothbrush to be retained in its operative position until the ribs are displaced out of the grooves and displaced through approximately 180° whereupon theribs 66 relocate in thegrooves 67 and the members are then held securely in the inoperative position. - In the embodiment of Figs. 14 and 15 (not forming an embodiment of the invention) a non-pivoting toothbrush arrangement is shown wherein there is provided an axially displaceable knob or
rotary member 68 biassed by spring means 69 outwardly oftoothbrush container 70 having bristlesupport 71 extending therefrom and carrying bristles 13. A piston or pressure member 72 of generally rectangular form withinclined faces 78 is carried by arod 79 on which there are located a plurality ofconical members 80 arranged to point in the same direction and resilient so as to be displaceable through a correspondingly shaped conical aperture 77' in member 72. Theportions 80 are shaped so as to be capable of being drawn through aperture 77' whereupon they are reduced or compressed in diameter somewhat and on passing therethrough, from right to left in Figs. 14 and 15, they then expand and act against the flat surface of member 72 acting to be pushed thereagainst and not be displaceable through the aperture 77'. On opposite walls ofrectangular paste container 70, there are located a plurality of parallel, step-like teeth 81 forming a ratchet-like arrangement co- operably engageable with the slopingsurfaces 78 of member 72 such that when the member 72 is urged byportion 80 acting against the left-hand face thereof, as shown in the drawings, member 72 may be displaced step-like along from groove to groove between the teeth 81 -the resilience of the casing and teeth and theportions 80 permitting this action. This opposite ratchet-like arrangement enables the member 72 to be stepped along the teeth ofratchet 81 by depressingknob 68. Thespring 69 causesconical portions 80 to be drawn stepwise through the member 72 whilst the non-sloping surfaces of theteeth 81 prevent movement of the member 72 towardsknob 68. The next depressions or axial movements of theknob 68 into thecontainer 70 causes a stepwise movement of the member 72 within thepaste container 70 thereby causing stepwise urging of the paste through the paste duct 71' and to thebristles 13. Such step-like paste dispensing mechanism may be provided in the earlier arrangements in place of the threaded screw member as would be readily apparent to persons skilled in the art without undue major modification - various possible arrangements also exist for modifying the paste duct closure means. - A paste duct closure means is shown adjacent the aperture leading to the
bristles 13 and comprises a displaceable cylinder or likemember 82 spring biassed byspring 83 into a closed position sealing off theaperture 84 leading to thebristles 13. Upon movement of themember 77 by action onknob 68 the paste is urged under pressure throughduct 71 and such pressure displaces theclosure member 82 against the action of the spring thereby opening the paste duct to theaperture 84 and thebristles 13 and permitting paste to be urged to the bristles. Upon reduction of paste pressure, thespring 83 causes themember 82 to close the paste duct. This arrangement might be provided for the earlier disclosed embodiments without undue modification and such is shown in greater detail in Fig. 16. - In Fig. 17 an arrangement is provided which is particularly suitable for use with a rotary, axially displaceable threaded member as an extension thereof so that rotation of the
extension 85 causescircular closure member 86 to move through 180° thereby opening thepaste duct 84 for a short while permitting paste to be urged to thebristles 13. - Fig. 18 shows an alternative arrangement of paste duct closure means wherein a polythene or other plastics material
flexible finger 87 extends from the aperture in the paste duct and is closed by the pressure of the surroundingbristles 13 although does open under paste pressure to permit paste to be discharged into an upper region at the top of thefinger 87 in the upper region of thebristles 13. - Fig. 19 shows a still further alternative arrangement of the paste duct closure means comprising a number of
ribs 88 joined together with a flexible film or the like material 90 and may be clipped onto the pasteduct outlet aperture 91 such that the member by virtue of the resilient film 90 closes together to form a stack-like arrangement as shown in Fig. 19a through which paste may be urged upon action on the paste displacing means but which close together to seal off the aperture when the paste pressure drops. - In an alternative arrangement (not shown) bristles 13 may be arranged in sloping manner or groups thereof in sloping manner about the paste duct aperture so as to form a conical or surrounding abutting arrangement through which paste may be urged under pressure but which act to close the paste duct when the pressure is relieved.
- Fig. 20 shows an alternative arrangement of paste duct closure means whereny a
flexible tube member 92 is located within the paste duct and forms part thereof and upon relative displacement of the bristle support member relative to saidtube 92 thetube 92 is displaceable upwardly into thebristles 13 as shown in broken line to permit paste to be displaced therefrom via previously described paste dispensing means (not shown). The bristle head may be then retracted or displaced by spring means relative to thetube 92 to assume the position as shown in Fig. 20 whereby the end of the paste duct formed by the end of the flexible tube is closed. - An alternative arrangement is shown in Fig. 21 whereby the
bristles 13 are supported on adisplaceable member 93 spring biassed by a resilient portion 93' into the open position as shown but which bristlesupport 93 is used with a folding arrangement whereby theedge 93" strikes against a surface causing displacement in the direction of the arrow and closure of the paste duct means 94. - Figs. 22 and 23 show a schematic perspective view and section of an alternative arrangement of the paste duct closure means whereby a
closing piston 95 is displaceable in theduct 96 leading to thebristles 13 from open to closed position by virtue of manual action on thetrigger 97 as shown. - Fig. 24 shows a
cover cap 98 with paste duct closure member 99 which may be provided so as to locate over thebristles 13 and thereby provide hygenic cover whilst at the same time providing a bristle paste duct closure member pin. - Fig. 25 (not forming a part of the invention) shows a simple arrangement with a rectangular or other non-circular
section paste container 100 carrying a rotary threadedspindle 101 with paste pressure or displacingmember 102 and aknob 103 which upon rotation causes themember 102 to move along threadedspindle 101 and urge paste towards paste duct closure means 82, 83 which is similar to that described in Figs. 15 and 16. - In the arrangement of Fig. 26 (nor forming a part of the invention) an extension 101' to the threaded
member 101 is provided carrying aclosure cylinder 82 which is spring biassed to a closed position by aspring 83. Therotary knob 103 is provided on the other end of the threadedspindle 101 to effect rotary movement of the spindle. Aplate 104 secured in thecontainer 100 has a spring biassing means 105 acting thereagainst and against a box-like member 106 also carried by the threadedmember 101 such that on axial displacement of the threadedmember 101 thespring 105 is compressed as is the spring biassing means 83 of pasteduct closure member 82 so as to permit theduct 107 leading to thebristles 13 to be opened and paste to be discharged. On relaxation of the axial pressure on theknob 103 the springs then act to return the threaded member and components carried thereby to thereby close thepaste duct 107 by means ofclosure member 82. - Fig. 27 is a schematic cross-sectional illustration of a further embodiment with paste displacing means and paste duct closure means similar to previous embodiments. Fig. 28 is an exploded fragmentary schematic perspective of the hinge interconnection between the paste container and brush member and this comprises a
hinge member 108 secured to thecontainer 10 and brush member and having a cut out portion 108' to permit folding into the inoperative position shown in broken line. Aflexible tubular member 109 is located in sealing arrangement withpaste duct 110 in thecontainer 10 andduct 33 inmember 11. The tubular member will be of such nature as to permit required folding and may even be such as to collapse and close the paste duct in the folded position if desired. - The provision of a toothbrush with toothpaste within the handle and with a brush member pivotable relative thereto is of considerable adavantage to persons desiring a compact and simple teeth cleaning arrangement which is readily portable.
- In the previously described arrangements various components or mechanisms may be interchanged as desired. Further various modifications and changes may be made without departing from the scope of the invention. For instance, the brush member may be hingedly mounted on a side of the paste container and have a duct communicating with the paste container interior in the operative position. The rotary spindle with two oppositely threaded portions may be provided and two paste pressure members also provided acting in opposite directions and moving together to displace the paste.
- The device is preferably made of plastics material and mouldings, snap-fit connections, etc., will be apparent to persons skilled in the art.
- The paste may be contained in a flexible plastics bag or tube open at one end and utilizable as a refill - dispensing to bristles being effected by collapsing bag by suitable means. A compartment may be provided (such as shown in Figs. 1 or 27) preferably in the rotary knob member when provided for receiving a bobbin of dental floss and/or a toothpick device, preferably formed on a flat sheet of shaped flexible plastics material (not shown).
- It will be appreciated that many modifications or changes can be effected in putting the invention into practice. For example, the step-wise displacing means with ratchet-like teeth for enabling paste to be urged through the ducting means such as shown in the arrangements of Figs. 7, 7a or Figs. 14 and 15 may be included in an arrangement where the brush member is pivotably connected to the handle for containing paste. Further, in one form of such embodiment, the bristles of the brush member may be locatable in the folded position within a space or recess within the handle member and the step- wise operating displacing means for the paste to be so arranged that in operation, paste may be urged through paste ducting means and into the recess and onto the bristles when the brush is in the folded position.
