  • Publication number: 20210227963
    Abstract: An oral care implement having a head with a bristle bearing surface. The oral care implement may include a central bristle tuft extending from a central portion of the bristle bearing surface, the central bristle tuft terminating in a domed distal surface. Furthermore, the oral care implement may include a plurality of perimetric bristle tufts extending from the bristle bearing surface and arranged to circumferentially surround the central bristle tuft. Each of the perimetric bristle tufts may have an inclined distal surface that slopes downward towards the central bristle tuft. The bristle bearing surface of the head may have a total surface area (TSA), and the toothbrush may include a tooth cleaning element field having X number of tooth cleaning elements that collectively occupy a total cleaning element area (TCEA) such that 1 X × T ? C ? E ? A T ? S ? A = Z and L is in a range of 0.04 to 0.065.

  • Publication number: 20210227964
    Abstract: An oral care implement having a head with a plurality of cleaning elements coupled thereto and extending therefrom. In the exemplified embodiment, the cleaning elements have a plurality of bristle tufts each including a plurality of bristle filaments. In one aspect, the oral care implement may include a first bristle tuft having inner and outer filaments with the outer filaments being taller than the inner filaments and a second bristle tuft having inner and outer filaments with the outer filaments being shorter than the inner filaments. In another aspect, the oral care implement may include a bristle tuft having inner and outer filaments with the inner filaments being either taller or shorter than the outer filaments, and whereby distal ends of the inner and outer filaments are angled relative to an axis of the bristle tuft.

  • Publication number: 20200288858
    Abstract: An oral care product array includes a handle component and multiple refill components therefor. The handle component includes a power source. A first refill component includes a first light generating module which emits light in a first spectrum from the first refill component. A second refill component includes a second light generating module which emits light in a second spectrum from the second refill component. Each refill component has a coupled state, when coupled to the handle component, and a decoupled state, when decoupled from the handle component. When the first refill component is in the coupled state, the first light generating module is powered by the power source to emit light in the first spectrum. When the second refill component is in the coupled state, the second light generating module is powered by the power source to emit light in the second spectrum.

  • Patent number: 10426255
    Abstract: A toothbrush is provided that includes a base component having a gripping region and an oral engaging region defining a longitudinal axis along a length of the oral engaging region and a transverse axis along a width of the oral engaging region. The oral engaging region has bilateral symmetry with respect to the longitudinal axis and can comprise wherein the oral engaging region has bilateral symmetry with respect to the longitudinal axis and comprises a first distal region having an approximately concave contour tapering to a second middle region having an approximately convex contour and widening to a third proximal region having an approximately concave contour. The oral engaging region can support a plurality of cleaning elements along a front side and a plurality of soft cleaning elements along a second side opposite the first.

  • Publication number: 20190070326
    Abstract: An oral care sterilization system in one embodiment includes an oral care implement and sterilization unit. The oral care implement may be a toothbrush including tooth cleaning elements on a head portion and a first coupling member. The sterilization unit includes a housing and second coupling member that mutually engages the first coupling member to secure the toothbrush to the sterilization unit. Magnetic coupling may be used in one embodiment. The toothbrush may be mounted in a suspended manner from the sterilization unit. A sterilization element such as an ultraviolet light source disposed in the housing irradiates at least the toothbrush head portion to destroy bacterial contamination. In one aspect, the toothbrush and housing each include complementary thematic features sharing a common motif. The motif is of a nature to make brushing and care of the toothbrush more interesting for younger users.
