Definitions

  • the present invention relates to a strand-shaped profile body for cleaning teeth with a special shape. It further relates to a process for its preparation and its use for cleaning teeth.
  • Dental care caoutchoucs essentially consist of so-called chewing gum base.
  • This in turn consists of natural or artificial polymers such as latex, polyvinyl ether, polyisobutylene vinyl ether or polyisobutene.
  • Such Zahnchevkaugummis contain as a tooth-care agent usually pH-controlling substances, which thus counteract the formation of tooth decay (tooth decay).
  • Toothekaugummis due to their plastic behavior such Zahnchevkaugummis hardly contribute to cleaning the chewing surfaces or sides of teeth.
  • chewing gums generally have the disadvantage that they often have to be mechanically removed and disposed of due to their adhesive properties from the floor of public streets and squares, which means a considerable cleaning effort.
  • Dental wipes for example Oral-B Brush Aways TM , Gillette GmbH & Co. OHG, Germany
  • Oral-B Brush Aways TM Gillette GmbH & Co. OHG, Germany
  • They achieve a cleaning effect of the tooth sides by applying the cloth to a finger and by rubbing off the teeth.
  • the nature of the application of such teeth cleaning cloths in public for aesthetic reasons is poorly accepted and thus does not represent an alternative to the use of a conventional toothbrush.
  • US 4,149,815 discloses a chewable tooth cleaning device. This comprises 2.45 to 9.0 cm 3 of a substantially closed-cell compressible polymer foam having a substantially skin-free surface. The device is designed to clean exposed tooth surfaces.
  • the polymer foam has about 12 to 50 cells per linear centimeter, a water absorption of less than 1.0 mg / cm 3 after immersion in water for 24 hours, a tensile strength of at least 3.4 x 10 5 Pa, a pressure resistance of at least 5 , 5 x 10 4 Pa at 10% deflection and at least 8.3 x 10 4 Pa at 25% deflection, a tear strength of at least 1.38 x 10 5 Pa and is sufficiently elastic to be at least 90% of the uncompressed height almost immediately to recover after compression to 10% of uncompressed height.
  • NL 7810061 discloses a mouth hygiene device which is also referred to commercially as a dental care wheel.
  • US 2002/0106234 A1 discloses a chewable tooth cleaning device.
  • This chewable toothbrush is constructed of a flexible sheath, a plurality of bristles coupled to the sheath which protrude substantially from the exterior of the sheath, and a chewable center within the sheath and an inflatable capsule adjacent the chewable center in the sheath interior.
  • US 2005/0260027 A1 discloses a disposable or edible chewable toothbrush for cleaning teeth between meals.
  • the device comprises a chewable bristle holder with bristles attached to the holder, a cavity in the holder, a substance in the cavity and weak points in the holder, which prevent the content of the holder from leaking until the holder is compressed by chewing.
  • a disposable or edible brush is stored within a disposable or edible sleeve. When chewing, the sheath is broken or dissolves and releases its contents, which includes the brush and possibly a dentifrice.
  • a disadvantage of the described tooth cleaning devices is that they show an unsatisfactory cleaning effect on the sides of the teeth or on the recesses in the chewing surfaces. Also, their production is sometimes expensive.
  • WO 2007/121866 A1 discloses new chewing gums for the oral care sector based on polyurethane-polyureas, a process for the preparation thereof and their use.
  • WO 2007/121867 A1 discloses new chewing gums for the oral care sector based on foamed synthetic polymers, a process for the production thereof and its use.
  • Dental cleaning devices which due to their shape would have an improved cleaning effect on the sides of the teeth, on depressions in the chewing surfaces or on depressions of the sides of the teeth, as they occur in the transition between the side of the tooth and the gum, would be desirable. Furthermore, it would be desirable if the shaping would also emphasize a pleasant mouthfeel.

  • the profile body according to the invention comprises, seen in cross-section, a bottom section and two wall sections arranged opposite one another.
  • the bottom portion thus connects the two wall sections together.
  • the profile body is seen in cross-section U-shaped or H-shaped.
  • the floor is present as a separate section in the profile body and not only represents the interface between two wall sections.
  • the recess facing sides of the wall portions may form a relatively small angle to the central axis of the cross-sectional profile and there is still enough space at the bottom of the profile body for the male tooth.
  • the central axis is the axis which also extends in the direction of the extent of the first and second wall sections.
  • the angle of the sides of the wall portions or, if the wall portions are irregularly structured, the angle of a straight line tangentially contacting the top and bottom bumps of the wall portion on the recess facing side may be, for example, in a range of ⁇ 5 ° to ⁇ 30 ° or from ⁇ 10 ° to ⁇ 20 °.
  • first and the second wall portion are configured so that the recess opposite edge to the outside, ie away from the recess, is curved.
  • the height of the cross section of the profile body results from its maximum extent in the direction of the wall sections, ie parallel to the wall sections. In other words, the height of the cross section is determined by the length of the wall sections. Perpendicular to this, the width is defined in cross section. In other words, the width of the cross section is determined by the distance of the wall sections to each other.
  • the profile body forms at least one recess for receiving a tooth.
  • This recess is, as seen in cross section, bounded by the bottom portion and by the two wall portions.
  • there is a recess in the case of a generally H-shaped profile there are two.

  • Curing while retaining the foam structure can already start during foaming. This is the case, for example, when using isocyanate / polyol mixtures to form the synthetic polymer.
  • a curing following the foaming takes place, for example, when using aqueous polyurethane dispersions, which are first foamed and then dried only for curing.
  • the curing can be carried out in addition to chemical crosslinking or physical drying and by lowering the temperature of a melt, gelling of plastisols or coagulation, for example of latices.
  • “Curing with preservation of the foam structure” means that the foamed mixture is converted to the solid state so that it does not collapse of the foam with loss of the cellular structure of the foam. In this case, foams are then obtained which have advantageous foam densities.
  • Curing by physical drying is preferably carried out at a temperature of 25 ° C to 150 ° C, preferably 30 ° C to 120 ° C, more preferably at 40 ° C to 100 ° C. Drying can be done in a conventional dryer. Also possible is drying in a microwave (HF) dryer.
