  • Patent number: 7579039
    Abstract: A method for coating a cleaning region of an interdental cleaning device, which includes preheating the cleaning region to a predetermined temperature. Then, immersing the preheated cleaning region in a coating agent. The coating agent including a flavoring agent encapsulated in a wax, thereby forming a coating on the cleaning region upon immersion. Next, a flow of air is forced across the coated cleaning region in a drip zone, thereby removing an excess portion of the wax and exposing at least a portion of the flavoring agent at a surface of the coating. Then, the coating is cured by cooling the cleaning region.

  • Publication number: 20090000048
    Abstract: An electric toothbrush features a handpiece and a detachable toothbrush head. The toothbrush head of toothbrush has a set of bristles and a coupling device for coupling it to a handpiece of the toothbrush. The toothbrush head includes a conduit for supplying a pasty, gel-type and/or liquid substance to be applied, in particular toothpaste. The coupling device has a conduit coupling for coupling the conduit to a conduit section on the handpiece side. A handpiece of the toothbrush has a coupling device for coupling the toothbrush head thereto. The handpiece includes a conduit for supplying a pasty, gel-type and/or liquid substance to be applied, in particular toothpaste. The coupling device has a conduit coupling for coupling the conduit on the handpiece side to the conduit on the brush head side. The conduit coupling comprises a control valve.

  • Publication number: 20070033757
    Abstract: The invention pertains to a toothbrush (1) with a brush head (2), from a surface (10) of which bristle clusters (11-17) protrude. According to the invention, at least one bristle cluster (11) is surrounded by an annular depression (21) in the surface (10). The invention improves the mobility of these bristles such that they are able to better penetrate into and clean the interdental spaces.

  • Patent number: 7146675
    Abstract: A handheld toothbrush with a brush head having a forward free end and a rearward portion. Provided at the forward free end of the brush head is at least one bristle tuft of a first set. Adjoining the first set in rearward direction is a second set of tufts comprised of several bristle tufts arranged serially on a ring and extending in the circumferential direction of the ring at an angle of inclination relative to the surface of the brush head. A third set of tufts adjoins the second set of bristle tufts in the direction towards the rearward portion. The tufts of the third set are inclined in the circumferential direction in opposition to the direction of the bristle tufts of the second set. As a result, these tufts are capable of penetrating optimally between the user's teeth, hence ensuring a better cleaning result.
