US Patent 10334941 Bottle brush with multiple bristle reaches

A bottle brush includes a handle and a brush head connected to the handle. The brush head has a longitudinal axis and further includes a barrel having a sidewall substantially parallel to the longitudinal axis. A first row of bristles extends from the sidewall at least in part transversely from the barrel to define a first bristle reach. At least two second rows of bristles extend from the sidewall at least in part transversely from the barrel to define a second bristle reach different from the first bristle reach. The at least two second rows of bristles may be spaced longitudinally from each other with the first row of bristles being longitudinally intermediate to the second rows of bristles.
