Definitions

  • the invention relates to a dental floss holder with a dental floss dispenser according to the preamble of the independent claims.
  • a tooth cleaning instrument is known from CH 591 844, which has a handle with an upwardly bent end. This end is fork-shaped and includes two prongs with a blunt end. Each tine has a notch at the blunt end. The notches of both tines run parallel to each other. An incision runs from each notch on the outside of the handle along the tine, turning slightly at the curved end towards the bottom. Close to the connection of the two tines is a button on the handle as a holding element. A longer piece of dental floss can now be wrapped around this button a few times, then placed in the incision of a tine, over the notch to the notch of the second tine.
  • a tooth cleaning device with a U-shaped clamping device is known.
  • a silk thread can be clamped between the two free ends.
  • the legs of the U-shaped clamping device intersect approximately in the central area.
  • the free ends are developed so that they run approximately parallel to each other.
  • a piece of dental floss can be inserted into the slots in the free ends and stretched by hand pressure on the thighs.
  • Each piece of dental floss is provided with pressed-on plastic balls at the free ends. After the floss has been inserted into the terminal slots, the plastic balls can be placed in opposing blind holes on the outside, whereupon the tensioning device is held by hand and tightened by being compressed.
  • the invention has for its object to design a dental floss holder, which keeps the dental floss under tension and still allows the tension of the dental floss to be adjusted by hand and yet very fine when inserted into the interdental spaces and during cleaning work To transfer movements in all directions with the dental floss holder from this to the dental floss.
  • the dental floss should be attachable to the dental floss holder in a very quick and simple manner. Even with violent back and forth movements, it must neither slip on the holder nor jump out of the fastening devices. Nevertheless, the interdental spaces should be able to be cleaned very gently and precisely, but the dental floss holder, especially in its front area, must not have any protruding or sharp-edged parts, as this could injure you.
  • An additional object of the invention is to provide a dental floss dispenser for use with the dental floss holder, which enables the dental floss to be put on the dental floss holder in a hygienically perfect manner, that is to say without contact.

  • Fig. 8 a preferred embodiment of the leg ends seen from the handle;
  • FIG. 11 shows a first version of a dental floss dispenser
  • FIG. 13 shows the use of the dental floss holder together with the dental floss dispenser.
  • a dental floss holder according to a first embodiment is shown in Figure 1. It preferably consists of a round rod made of stainless steel, which is bent in the middle in such a way that it forms two straight legs 1, which run away from one another at an acute angle. At the free ends 3 of these legs 1 there are fastening devices 30 for dental floss. According to the invention, the legs 1 are so long that they can be enclosed in the rear region 1, i.e. against the bend 4, with all or almost all of the hand and at the same time reach the rearmost teeth with the fastening devices 30 without the holding hand To touch your mouth. The rear region of the legs 1 against the bend 4 forms a handle region 11 of the dental floss holder.
  • the bend 4 is a resilient connection between the two legs 1, which spreads them in the front region 2 and exerts a tensioning force on them when the dental floss is inserted.
  • the two legs 1 are pressed together with the holding hand against the spring force of the bend 4 of the dental floss holder, approach the fastening devices 30 each other, so that the dental floss can be anchored to the fastening devices 30 described later.
  • the hand relaxes, the legs 1 diverge and the dental floss is tensioned by the spring force of the bend 4. This strong basic tension of the dental floss can be reduced as needed, or the dental floss can be partially relaxed by squeezing the holding hand more or less.
  • the legs 1 and the bend 4 of the dental floss holder can be made of resilient material and bent in a U-shape from one piece.
  • a sufficiently stiff and springy wire is particularly suitable.
  • a swivel joint can also connect the two legs, a spring being arranged between them, which spreads the legs in the same way.
  • Such a dental floss holder can be equipped with a dental floss cutter. This consists in that a slit, as wide or slightly wider than a dental floss thread, leads into an arm 1 in the vicinity of an anchoring. Inside this slot, a sharp blade is attached at an angle to the slot direction.
  • FIG. 2 Another embodiment of the dental floss holder, which is suitable for people with particularly large hands, is shown in Figure 2.
  • the legs 1 essentially form a slight curve outwards in the handle region 11, so that the dental floss holder has a greater width here than at the leg ends.
  • the difference to the previously described embodiment of the dental floss holder in this variant is that the two legs 1 in the foremost handle region 11 or somewhat in front in turn have a slight curve inwards, so that the legs 1 at this point and thus also the free ends 3, in the tensioned state of the dental floss, with the thumb of the holding hand can push something apart.
  • This has the advantage that the basic tension of the dental floss through the bend 4 has to be less high than in the previously described embodiments, because the tension can be increased at any time with the thumb as desired.
  • a further embodiment of the dental floss holder is that a rod, preferably made of stainless steel, is bent over in such a way that it forms a loop, as shown in FIG. 3.
  • the two legs 1 cross here.
  • the loop is of a shape, size and strength such that it forms a handle 11, which can be enclosed and pressed together with one hand.
  • the two legs are connected to one another at their cross point 4 with an axis in a scissor-like manner.
  • the two front regions 2 of the legs are shaped from the intersection 4 towards their free ends 3 such that they first diverge and run approximately parallel towards their free ends 3. At these free ends 3 there are similarly the fastening devices 30 for dental floss.
  • both legs 1 in the front area 2 are angled on the same side at an angle to the plane which is formed by the legs 1 in the handle area 11. This kinking of the leg ends can be used in all variants. This makes the dental floss holder particularly handy when cleaning the interdental spaces.
  • the handles 1 of all the variants of the dental floss holder described can be coated with a plastic or paint.
  • the plastic cover can increase the grip and the color can beautify the appearance.
  • the fastening devices 30 for the different embodiments of the dental floss holder each consist of a guide slot 31 and an anchoring on each leg 1, as is shown in FIGS. 5-10.
  • the width of the guide slot 31 corresponds to the diameter of the dental floss. It is essential that its sole 35, from the point where it is touched by the tensioned dental floss Z, which comes from the opposite fastening device, towards the other end of the guide slot, i.e. against its outer mouth 37, from the normal direction of tension N the floss deviates by an angle S of approximately 45 °.
  • This has the essential advantage that dental floss, which is anchored to the outer mouth 37 of the guide slot at the level of the sole or further down, is pulled through the guide slot 31 and from the opposite one
  • Fastening device is stretched forth, is forced to lie firmly on the inner opening 36 of the guide slot on the sole 35, even if the direction of floss during cleaning is strong from the normal tensioning direction N. deviates, for example in direction A.
  • the angled course of the sole 35, together with the narrowness of the guide slot 31, ensures that the dental floss always has firm contact with the dental floss holder at the same point even during vigorous reciprocating movements. This has the advantage that even very fine movements are always precisely transferred to the dental floss via the dental floss holder, which enables very precise work. This also prevents the dental floss from jumping out of the guide slots 31.
  • the dental floss can be placed more easily in the guide slot 31, it is widened a little like a funnel to the outside. Its walls have a small suit.
  • the two guide slots 31 of the fastening devices 30 preferably point towards one another. You can laterally, at right angles or obliquely to the legs in the region of the free ends in the legs 1, but also from the front into this. This can be seen from FIGS. 5, 6 and 7.
  • Anchoring surface 38 is designed such that it is at least as wide as the knot diameter of the dental floss.
  • FIGS. 6, 7 and 10 The arrangement of these elements of the fastening device 30 are also shown in FIGS. 6, 7 and 10.
  • Figure 6 shows this seen at a free end 3 of one leg 1 in a side view from the other leg. Only can the guide slot 31 can be seen with the sole 35.
  • Figure 7 shows the same free end 3 in a side view from outside the dental floss holder. Because of the angled position of the sole 35, all elements, guide slot 31, sole 35 and anchoring surface 38 are visible. A dental floss Z together with the knot is inserted into the fastening device 30.
  • the anchoring surface 38 is formed by the base of a flat depression.
  • a guide slot 31 of a fastening device 30 can be embedded in the end faces of the legs 1 at their free ends 3 parallel to these. Then the anchoring surface 38 is part of the wall of the guide slot on the side of a notch 39, which extends approximately at right angles to the outer opening 37 of the guide slot through the leg 1 and extends somewhat below the sole 35 of the guide slot.
  • FIGS. 8, 9 and 10 A preferred embodiment of the leg ends with the guide slots 31 is shown in FIGS. 8, 9 and 10.
  • the guide slots 31 of the fastening device 30 lead obliquely into the legs 1 in the region of their free ends 3.
  • the guide slots 31 are open against the handle 11.
  • the anchoring surface 38 also runs in an arc along the outer mouth of the guide slot 31.
  • the center C of this arch is preferably about 1/3 of the leg diameter from the inner end of the sole, respectively.
  • the arch-shaped course has the advantage that the angle of the floss / anchoring surface is always pointed when inserting a piece of dental floss and the knot of a floss thread always slides well in the direction of the sole and anchors itself there securely.
  • This embodiment is particularly suitable for use together with a dental floss dispenser according to FIGS. 11 and 12.
  • the dental floss dispenser 100 consists of a housing 101 with a dental floss supply 102 arranged inside.
  • the housing 101 has an opening 103 from which the dental floss is pulled out.
  • At least one first cam 105 with a groove 107 is arranged on the outside of the housing 101 on one side.
  • the width of the groove 107 corresponds to the cross section of the dental floss and becomes narrower towards the inside.
  • the dental floss can be pulled through the groove 107, but is retained on the buttons.
  • a blade 104 is attached to the housing, with which a piece of dental floss can be separated.
  • a second cam 106 is mounted at a distance of approximately one node diameter from the first cam 105.
  • the second cam 106 is also provided with a similar groove 107.
  • FIG. 13 shows the handling of the dental floss dispenser with the dental floss holder from left to right.
  • One end of the floss supply protrudes from the opening 103 and through the grooves 107 in the cams 105 and 106.
  • a button near the end of the floss is located between the two cams 105 and 106.
  • the floss holder is attached to the floss in the area between the flap Opening 103 and the first cam 105 pulled.
  • the dental floss automatically slides into the guide slot 31 in the dental floss holder 1.
  • the dental floss holder is lifted off and the end of the dental floss is pulled out of the groove 107 of the cams with the button.
  • the dental floss z lies against the anchoring surface 38 of one leg. Dental floss is thereby immediately drawn from the supply through opening 103.
  • the dental floss holder is now held on the other side of the cams, the subsequent dental floss coming to lie in the groove 107, a button after the second being located between the two cams and preventing further flossing of the dental floss.
  • the dental floss holder is now slightly compressed and the second leg is pulled over the tightened dental floss so that it slides into this guide slot 31.
  • the dental floss holder is then relaxed, whereby the next dental floss button rests on the anchoring surface 38 of the second leg.
  • the piece of dental floss is now stretched between the legs and can be cut off from the supply by pulling the loose dental floss, which is located between the holder and the cams, over a blade 104.

Abstract

On propose un instrument à fil dentaire avec une poignée comprenant deux branches (1) reliées à effet ressort pour la manipulation du fil dentaire, lequel présente à intervalles des épaississements. Le fil dentaire est tendu par l'effet ressort de l'instrument. On peut réduire la tension du fil dentaire en pressant légèrement la poignée selon les besoins du moment, lors du nettoyage des espaces interdentaires. Les dispositifs de fixation (30) présentent chacun une encoche de guidage dans laquelle on peut faire passer un morceau de fil dentaire (z), ainsi qu'une surface d'ancrage où le fil dentaire vient solidement s'ancrer grâce au n÷ud. La disposition et la géométrie des dispositifs de fixation (30) assurent un guidage précis et un bon maintien du fil dentaire sur l'instrument. Un dispensateur de fil dentaire (100) permet de tirer le fil dentaire (z) hors du dispensateur tout en exerçant une tension sur les dispositifs de fixation (30) de l'instrument.
