Definitions
- the invention relates to an interdental cleaner for cleaning interdental spaces and interspaces between bridgework and gums, which cleaner comprises a wire provided with brush hairs projecting in several directions therefrom.
- Such an interdental cleaner is known from Dutch patent No. 188.734 (Esro AG) .
- the wire is one metal wire, which is bent to comprise two parallel wire ends, which wire ends are twisted together, with brush hairs being provided between the windings, which brush hairs project in all directions therefrom.
- the entire metal wire is coated with a sealing layer of a wear-resistant, electrically insulating and soft elastic plastic material. In this way cleaning will not cause the user any pain resulting from oversentivity to galvanic effects occurring at exposed or carious dental cervixes and amalgam fillings.
- the metal of the twisted-together wire ends, between which the brush hairs are fastened can no longer oxidize, so that the hairs cannot come loose any more .
- the object of the invention is to provide a simple and elegant interdental cleaner, by means of which all interdental spaces and interspaces between bridgework and gums can be cleaned in an efficient and comfortable manner, and in order to accomplish that objective an interdental cleaner of the kind referred to in the introduction is characterized in that it comprises a wire holder, which can be provided at least partially round a finger, and that said wire is made of plastic material.
- the wire holder forms a natural "extension" of the finger, as it were, as a result of which the brush hairs can easily reach the interdental spaces in the back of the mouth from the correct position of use (controlled by the finger and the finger tip) as well.
- the wire is made of plastic material, in particular nylon, thus avoiding all the aforesaid drawbacks of the known metal wire; more in particular no permanent deformation will take place, quite the contrary, the wire is flexible, whilst an electrically insulating coating to protect against galvanic effects need not be provided.
- the brush hairs are connected to the wire by means of sprue techniques (the so-called two-component injection moulding) - or, in another preferred embodiment, by means of ultrasonic techniques.
- the phenomenon of brush hairs coming loose which is observed in the prior art, thus belongs to the past. It is preferred to make the wire of a hard nylon, whilst the brush hairs are made of a flexible plastic or a flexible rubber.
- said wire is detachably connected to said wire holder.
- the advantage of the wire being detachable is not only the fact that the wire can be bought separately, whether or not packed in combination with other wires (due to wear the wire will usually have to be replaced sooner than the wire holder) , but also that each individual within a family will have his or her own wire to match that individual's teeth, whilst all family members still use a common wire holder.
- said wire holder comprises an annular part.
- This part forms a "sleeve", as it were, which can be slid over a second phalanx.
- the annular part preferably comprises an interruption, so that the flexibility thus provided renders the wire holder suitable for different finger thicknesses.
- said wire holder comprises a wing-shaped part.
- the user can take hold of the wire holder with two finger tips, one of which is present within the wing-shaped part, as it were, and be positioned inside or near the mouth cavity so as to clean all interdental spaces in an efficient manner.
- said wire and said brush hairs are made of plastic material, preferably nylon. This gives the wire the flexibility and pliancy required for cleaning, without undergoing any permanent deformation. As already said before, the occurrence of galvanic effects is excluded by this selection of materials . Furthermore the wire itself also has a cleaning effect, because all its physical properties are comparable with those of the brush hairs.
- an injection moulding technique a laser technique or a micro-cutting technique is used for forming the wire and the brush hairs in one piece of one material, the so- called “ mono material” .
- a laser technique or a micro-cutting technique is used for forming the wire and the brush hairs in one piece of one material, the so- called “ mono material” .
- mono material the unit of wire and brush hairs is " cut" from one starting material by means of a laser or by means of a die-cutting operation.
- the brush hairs have rounded ends. This prevents the teeth and the root surfaces from being damaged.
- the brush hairs have a flat contact surface, so that a larger contact surface (and thus an enhanced cleaning effect) is created than would be the case with brush hairs which have an entirely round cross-section.
- said wire has a length of 1 - 2.5 cm, preferably 1.5 - 2.5 cm, more in particular about 2 cm.
- a wire of this type by manipulating, in particular rotating, the wire holder in the mouth cavity.
- the wire can be selectively shortened to a particular length. This plays a role especially when the wire is made in a continuous length at the factory and must be shortened to a particular length - depending on the customers' wishes - preferably by cutting or die- cutting.
- said brush hairs have a length of 1 - 8 mm, preferably 3 - 5 mm.
- the invention also relates to a wire holder and/or a wire suitable for being used with an interdental cleaner according to the invention, if a detachable connection between the wire holder and the wire is used.
- Figures la, lb, lc, Id and le are a plan view, a rear view, a side view, a front view and a bottom view respectively of a special variant of an interdental cleaner according to the invention
- Figure 2 corresponds with Figure 1, with this understanding that a different preferred variant is sho n;
- Figure 3 is a diagrammatic, perspective view of a brush hair used with the interdental cleaner shown in Figure 1.
- Figure 1 shows an interdental cleaner according to the invention consisting of a wire holder 1 provided with an annular part 2, which is interrupted by a slot 3. This makes it possible to slide the wire holder over any finger of any thickness, whereby the finger tip extends with the (global) centre of the first phalanx to the end 4 of the wire holder.
- Wire 5 has a length of about 1.5 mm and can be detachably connected at the user's home to wire holder JL by means of a snap connection. Also other connections are possible, for example clamps etc.
- the cleaner constitutes an "extension" of the index finger, as it were, it can readily be moved to any desired position inside or near the mouth cavity for ideally cleaning interdental spaces.
- the whole is made of plastic material, so that the required flexibility is obtained without any risk of permanent deformation.
- Plastic has the added advantage that the user will not experience any pain due to galvanic effects occurring at exposed or carious dental cervixes when cleaning his or her teeth. This makes it possible to refrain from the use of insulating coatings, which are used in the aforesaid prior art .
- Figure 2 corresponds with Figure 1, and like parts are numbered alike, with this understanding that a wing- shaped part 6 is used instead of an annular part 2.
- the index finger for example, is present in the wing-shaped part, whilst another finger, for example the thumb, is present at the underside of wing-shaped part 6.
- Figure 3 is a perspective view of a brush hair used with the cleaner shown in Figure 1. Since the brush hair has a flat contact surface 7, a larger contact surface with parts of the teeth is created, which leads to an enhanced cleaning effect in comparison with a brush hair having an entirely round (smooth) cross-section. Also the brush hair shown in Figure 3 comprises a rounded end 8, so that the risk of damage to the teeth and the root surface is ruled out .
