Patent number: 7036180Abstract: A toothbrush for use on domestic pets, comprising a toothbrush head with each end curved upward at roughly 30 degree angles, and four sets of soft bristles attached to the head. Three sets of bristles are attached to the front face of the brush head, with two sets positioned opposite each other on each upward curved end of the head and the third set of bristles positioned in the center in the middle region, perpendicular to the toothbrush head between the other two sets, thereby providing coverage of the mesial, distal and occlusal surfaces of the teeth simultaneously. The fourth set of bristles is attached to the back side of the toothbrush head, thereby propping open the jaw and softening the bite while cleaning and massaging the opposing teeth at the same time that the other three sets of bristles are doing the primary cleaning. The toothbrush handle is attached to the center of the head for ease of use and the ability to reach the back molars.Type: GrantFiled: August 11, 2004Date of Patent: May 2, 2006Inventor: Barbara Hanlon

Patent number: 6810550Abstract: The toothbrush consists of a brush head with bunches of bristles (2, 3, 4) arranged in a longitudinal bristle bed (1) and a handle (6), which is connected to the bristle bed (1) by a connecting part (5). The length of the bunches of bristles (3, 4) varies in the longitudinal direction of the bristle bed (1) in a wave shape. The first bunches of bristles (2) are situated at the two outer sides of the bristle bed (1), have split bristle ends and are of essentially the same length. The second bunches of bristles (3, 4), whose length varies in the longitudinal direction of the bristle bed (1), are situated between the two outer sides of the bristle bed (1). The inventive toothbrush has an improved cleaning action, especially for interdental spaces but also for the gingival line.Type: GrantFiled: April 18, 2002Date of Patent: November 2, 2004Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Peter Wuelknitz, Ruediger Vetter, Yvette Kosmetatou

Publication number: 20040163195Abstract: A toothbrush has a head, and a handle; the head is formed with upper and lower portions joined to each other, which together have an inverted L shaped cross-section. The upper portion of the head is joined to the handle such that the head is rotary. The head has first and second bristles on a lower side of the upper portion, and an inner side of the lower portion respectively. Thus, the first and the second bristles can be pressed against, and moved over, top and one of lateral surfaces of a row of teeth for cleaning both of them respectively at the same time; the head turns to change orientation thereof relative to the handle according to curvature of different sections of a row of teeth, on which it is being moved along, thus increasing smoothness of movement thereof.Type: ApplicationFiled: February 25, 2003Publication date: August 26, 2004Inventor: Shih-Chieh Pao
