Definitions

  • This invention relates to hand-operated brushes, to toothbrushes, and in particular to portable toothbrushes intended to be carried on or with the person during any type of occupation or activity.
  • PROBLEM TO BE SOLVED PRIOR ART The problem to be solved is to design a simple, usable portable toothbrush which holds toothpaste yet will not leak paste, and which is convenient to use almost anywhere and includes means for applying the toothpaste to the ends of the bristles when required. This would keep the working area and indeed the whole brush in a more hygienic state, because it is easier to clean after use.
  • this invention provides a toothbrush of the type having a brush including bristles mounted near one end (the head) of a shaft, a handle at the other end of the shaft, and a hinge or fold between the head and the handle, wherein the handle includes means for the storage and delivery, from time to time, of controlled quantities of toothpaste, and hinged covering means for covering the shaft and head when the toothbrush is in a first, closed position so that the head and bristles are protected from contamination.
  • the handle includes a depression having a floor and sides, which depression surrounds the bristles when the brush is folded and closed.
  • the depression includes at least one aperture connected by a corresponding conduit to a means for storage of toothpaste.
  • the floor of the depression is configured in order to better apply the toothpaste to the bristles.
  • the means for storage of toothpaste is provided with expression means capable of causing a controlled amount of toothpaste to emerge from storage into the depression and against the bristles so that a desired amount of toothpaste is made available ready for use.
  • Preferred toothpaste expression means comprise pressure applied manually against the reservoir.
  • One preferred means is end-on pressure from a plunger forced along the cavity containing the toothpaste by finger pressure.
  • Another preferred means is digital pressure applied through a longitudinal slot to the exterior.
  • a further preferred means is pressure applied by a slider passing through a longitudinal slot to the exterior.
  • the means for storage of toothpaste includes an at least partial transparent wall or window through a wall, so that the amount of stored material is visible to a user.
  • the invention provides a filled cartridge witi in a cavity; a force- actuated valve upon one end of the cartridge in communication with a delivery channel to the depression, and user access to means to apply force to the valve so that some of the contents of the cartridge are sent through the delivery channel into the depression.
  • a preferred filling for the cartridge comprising a dental hygiene composition (such as a gel) mixed with a food-grade propellant.
  • a dental hygiene composition such as a gel
  • the means for actuating the valve is protected from inadvertent actuation.
  • the invention offers a free-floating tube of toothpaste within a container for manual application to the bristles.
  • the invention offers a further storage space within the dental care device for holding beads of a dental or oral hygiene composition.
  • the invention is designed to accept inserts containing toothpaste, one of which inserts may be placed into the depression and may be squeezed in order to release a desired amount of toothpaste.
  • Fig 1 is a diagram showing an example toothbrush according to the invention, in a closed configuration.
  • Fig 2 is a diagram showing an example toothbrush according to the invention, in an open configuration.
  • Fig 3 shows a plunger type mechanism for ejecting toothpaste against the bristles.
  • Fig 4 shows a squeezable bag which may be squeezed in order to eject toothpaste against the bristles.
  • Fig 5 shows a side opening slot into the storage space, with a slider to compress the squeezable bag in order to eject toothpaste against the bristles.
  • Fig 6 shows a rotatable screw drive for advancing a plunger in order to eject toothpaste against the bristles.
  • Fig 7 shows a version of the invention employing a propellant plus a toothpaste in a cartridge for storing and delivering toothpaste.
  • Fig 8 shows a system using containers or boxes of a toothpaste which can be 90 inserted into a deepened depression, and squeezed in order to express toothpaste.
  • Fig 9 shows variations in the configuration of delivery slots within the depression against which the bristles are placed.
  • a toothbrush according to the invention generally includes a folding brush and a 95 handle. It is adapted for portable use. The handle includes a depression which accommodates the bristles when the brush is folded closed. Means to cause a desired amount of toothpaste to emerge from storage into the depression and against the bristles when required conveniently provides a loading of toothpaste ready for use.
  • FIG. 100 This example shows some features, at least in principle.
  • the entire toothbrush 100 is shown folded for storage/carriage in Fig 1 and in a ready-to-use unfolded position in Fig 2.
  • An outer shell 101 includes a hinged lid (shown open as 101A and with a dotted line to indicate direction of opening in Fig 2). (Although the hinge is shown opening in a plane parallel to the base of the bristles it may open in other axes such as the
  • the hinge may be a moulded plastic equivalent hinge lacking separate, sliding parts.
  • the preferred toothbrush has conventional bristles 103, a shaft 102, and a hinge 110 which can rotate through 180 degrees and preferably includes a detent so that it is semi- locked at either extreme. (Such detents, being part of the art, can be inserted by those
  • the hinge is anchored to a body which includes, inside a relatively rigid outer shell, a cavity 109 for holding toothpaste, an exit 108 for the toothpaste to be used, an optional non-return flap 107, and a feeder line or lines 106 which lead toothpaste into the depression 105 where it will be picked up by the bristles.
  • the optional non-return flap will help in preserving
  • Various ratchet and screw- advance mechanisms for advancing the plunger are also usable; one version (see Fig 6.) includes a central coarse screw 602 running the length of the cavity, a plunger 601, having a threaded bore like a nut threaded over the screw, and plunger advance means
  • a one-way valve 107 is an optional addition.
  • the brush head may be removed for replacement or simply for a change, optionally by detachment at the hinge 110.
  • Fig 4 we assume that the replaceable bag 401 which contains toothpaste has been opened and attached to the base of the cavity at a thread 402, or an interference fit or some other means of making a reversible yet secure connection. Expression of toothpaste is now a matter of applying pressure to the bag,
  • Fig 8 shows yet another way of providing toothpaste refills.
  • small blocks (804, 802, 803) which may be stored loosely within the handle can be inserted (as 801) in the (in this case deepened) depression 105 of the portable toothbrush, and squeezed to liberate toothpaste.

  • Fig 9 shows some variations in the configuration of the depression.
  • 901 shows a cross- section through a simple version in which the depression has a flat floor with apertures 902.
  • 903 and 907 show variants in which a raised aperture delivers toothpaste more within the bristles.
  • 905 shows a re-entrant version and it may be that pushing the bristles into the depression will help to pick up the toothpaste that lies within..
  • Various patterns All of these designs lend themselves to manufacture using primarily injection moulding techniques so that the invention can be commercialised without problems.
  • EXAMPLE 2 Handling a viscous material (toothpaste) has always been an obstacle in portable tooth- 160 brush design.
  • a preferred filling for the cartridge would be a dental hygiene composition (such as a gel or mousse- type toothpaste with or without an abrasive component) mixed with a food-grade propellant such as is used for whipped cream.
  • a suitable dental care device would include a cavity within the handle that would fit this cartridge neatly, so that a protective 165 cap can be applied over the entire cavity.
  • the cartridge is fitted with a force-actuated valve upon the end of the cartridge placed in communication with a delivery channel to the depression, and may be made with a tapered shape for strength and so that people cannot insert a refill in the wrong direction.
  • the user applies force through a suitably protected (against 170 inadvertent triggering) mechanism to the valve so that some of the contents of the cartridge are sent through the delivery channel into the depression, for picking up on to the brush.
  • the variety of toothpaste used here is relatively fluid so that it can flow more 175 easily after the application of pressure through a delivery conduit and into the depression.
  • More flowable toothpastes include the "gels" with methyl cellulose or similar viscosity modifiers and either a reduced amount of abrasive material (normally 50% dicalcium phosphate) or a changed type - such as hydrated silica.
  • the description given here illustrates some novel aspects of a toothbrush according to 180 this invention. Of course, it may be combined with other inventions in the area - of which there are many - such as bristle end shape, head shape, head size, head angle, and so on - yet still maintain its novelty.
  • This invention combines the functions of a toothbrush with the advantages of being a 185 self-contained and portable version of a toothbrush.
  • the cover 101 A helps protect the head, shaft, and bristles of the toothbrush from contamination when the invention is not in actual use.
  • the invention avoids the problem of prior-art devices which would deliver toothpaste to the bristles from within the shaft to the base of the bristles.
