Definitions

  • the present invention relates generally to ansate oral care implements, and specifically to toothbrushes, either manual or powered, that have a handle and a head having cleaning elements for oral cleaning.
  • a toothbrush is used to clean the teeth by removing plaque and debris from the tooth surfaces.
  • Conventional toothbrushes provided with a flat bristle trim are limited in their ability to conform to the curvature of the teeth, to penetrate into the interproximal areas between the teeth, to sweep away the plaque and debris, and to clean along the gum line. Additionally, such toothbrushes have a limited ability to retain dentifrice for cleaning the teeth.
  • the dentifrice typically slips through the tufts of bristles and away from the contact between the bristles and the teeth. As a result, the dentifrice is often spread around the mouth, rather than being concentrated on the contact of the bristles with the teeth. Therefore, the efficiency of the cleaning process is reduced.
  • toothbrushes were developed having two or three circular brush sections which are arranged within holders that may be screwed into mating receptacles in the tooth brush handle so that they can be removed and replaced as needed.
  • Each brush section contains stiff cleaning elements and is spaced from the other along the longitudinal axis of the handle at a distance less than the thickness of a tooth so that the brush operates on both the lingual (inside) and facial (outside) surfaces of the teeth.
  • Another existing toothbrush includes a head containing a flexible, rubber-like prophylaxis polishing cup or "prophy cup” similar to that used by dental personnel to professionally clean teeth.
  • This prophy cup is loaded with toothpaste by the user and applied to the teeth.
  • the "soft rubber-like prophy cup device follows the contours of teeth more effectively than bristles.”
  • a ring of cleaning elements (“bristle tufts") are placed about the periphery of the toothbrush head which co-act with the prophy cups to clean the user's teeth and gums.
  • elastomeric prophy cups and bristle tufts have become more common as a way of improving cleaning efficiency and maintaining the dentifrice in place during brushing.
  • One example of the combined use and strategic arrangement of elastomeric prophy cups and bristle tufts is a toothbrush having a head portion comprising a plurality of inner loops formed by elastomeric walls. The central inner loop is surrounded by outer loops formed of bristles. A central cleaning element, formed as a bristle tuft, is located within the elastomeric inner loop.
  • a toothbrush having a head portion comprising a plurality of soft elastomer prophy cups surrounded by bristle rings.
  • a toothbrush exists wherein the centralized prophy cups are formed by groups of densely packed cleaning elements that are surrounded by bristle rings.
  • the bristle rings in this toothbrush are also disclosed as having one or more tufts at an inclination.
  • WO 2011/070549 A1 discloses a toothbrush having a handle and a toothbrush head at whose top side first, second, and third cleaning elements are provided for cleaning teeth.
  • a toothbrush according to the present invention is defined in claim 1. Preferred features are defined in the dependent claims.
  • the invention is discussed in terms of a manual toothbrush incorporating the subject arrangement of cleaning elements.
  • the invention could be in the form of other oral care implements including a soft-tissue cleansing implement, a powered toothbrush, or other ansate implement designed for oral care.
  • the toothbrush 100 generally comprises a handle 110 and a head 120.
  • the handle 110 provides the user with a mechanism by which he/she can readily grip and manipulate the toothbrush 100.
  • the handle 110 is generically illustrated and may be formed of many different shapes, sizes, materials and a variety of manufacturing methods that are well-known to those skilled in the art. If desired, the handle 110 may include a suitable textured grip (not shown) made of elastomeric material or can be a multi-part construction. Stated simply, the details of the handle 110 are not limiting of the present invention and, thus, require no further discussion for purposes of the present invention.
  • the toothbrush 100 extends from a proximal end 112 to a distal end 113 along a longitudinal axis A-A (illustrated in FIG. 2 ).
  • the head 120 is operably connected to the handle 110.
  • the head 120 and handle 110 of the toothbrush are preferably formed as a single unitary structure using a molding, milling, machining or other suitable process.
  • the handle 110 and head 120 may be formed as separate components which are operably connected at a later stage of the manufacturing process by any suitable technique known in the art, including without limitation thermal welding, a tight-fit assembly, a coupling sleeve, adhesion, or fasteners.
  • the head 120 and handle 110 are of a unitary or multi-piece construction (including connection techniques) is not limiting of the present invention.
  • the head 120 generally comprises a front surface 121 and a rear surface 122.
  • the front surface 121 and the rear surface 122 of the head 120 can take on a wide variety of shapes and contours, none of which are limiting of the present invention.
  • the front and rear surfaces 121, 122 can be planar, contoured or combinations thereof.
  • the rear surface 122 may also comprise additional structures for oral cleaning, such as a soft tissue cleanser.
  • a soft tissue cleanser is disclosed in U.S. Patent 7,143,462, issued December 5, 2006 to the assignee of the present application.
  • the head 120 is normally widened relative to the neck 111 of the handle 110, it could in some constructions simply be a continuous extension or narrowing of the handle 110.
  • the head 120 also comprises a distal periphery 124, a first lateral periphery 125, a second later periphery 126, and a proximal periphery 127.
  • the distal periphery 124, the first lateral periphery 125 and the second later periphery 126 are bound by a peripheral side surface 123 of the head 120.
  • the proximal periphery 127 is defined where the head 120 transitions into the neck 111.
  • a collection 130 of cleaning elements are provided on the front surface of the head 120 for cleaning contact with an oral surface, preferably teeth. While the collection 130 of cleaning elements is particularly suited for brushing teeth, the collection 130 of cleaning elements can also be used to clean oral soft tissue, such as a tongue, gums, or cheeks instead of or in addition to teeth. As used herein, the term "cleaning element" is used in a generic sense to refer to any structure that can be used to clean or massage an oral surface through relative surface contact.
  • cleaning elements include, without limitation, filament bristles, fiber bristles, nylon bristles, spiral bristles, rubber bristles, elastomeric protrusions, flexible polymer protrusions, co-extruded filaments, flag bristles, crimped bristles, anti-bacterial bristles and combinations thereof and/or structures containing such materials or combinations.
