An toothbrush having a handle and a head. The handle may include a first component and a second component covering at least a portion of the first component. The first and second components may be chemically compatible. The first and second components may both comprise a hard polyolefin. The first and second components may have different transparencies. In one aspect, the first component may be opaque and the second component may be transparent or semi-transparent. In some aspects, the handle may also include a third component comprising a thermoplastic elastomer. Furthermore, there may be at least one projection extending outwardly from an outer surface of the first component.

A toothbrush handle includes a support structure formed of clarified polypropylene and a body formed of thermoplastic elastomer disposed on the support structure. The support structure includes a web having a thickness in a first direction orthogonal to an axis of the toothbrush handle of less than 2 millimeters and at least one rib depending from the web and having a thickness in a second direction, orthogonal to the axis and angled relative to the first direction, of less than about 2 millimeters. The body at least partially covers the web and the at least one rib. The handle has a light transmissivity of greater than 40% through a portion of the handle at which the body covers the web and the at least one rib.

A cleaning device, in particular a toothbrush, with a handle body consisting of a handle part, a head part and a neck part connecting the handle part to the head part. The head part has applied to it one or more applicator and/or cleaning elements, which form a bristle area which has at least one outer side and/or an upper side. At least one of the applicator and/or cleaning elements on the at least one outer side and/or an upper side of the bristle area and/or the handle body is/are marked or printed with a marking/color medium.

An outer elastomeric layer forms a nonogonal-shaped hollow tube for a finger toothbrush to be used by an adult caregiver to brush a child's teeth. The toothbrush has a first, rigid portion with a rigid inner lining configured to receive a middle phalange of the caregiver's finger and a second, flexible portion configured to receive a distal phalange of the caregiver's finger. The rigid inner lining may further comprise extensions and depressions to spread the pressure from a child's bite. The second, flexible portion may allow for better tactile response when the toothbrush is in the mouth of a child.

An anti-tipping oral hygiene instrument exchanging structure includes a handle member attachable to a base member that includes a weight element, a circular curved section formed on the weight element, a base engaging section formed on the weight element, and a plurality of placing sections formed on the base member. The circular curved section is used in combination with the weight element to prevent the handle member from tipping over. The handle member has a handle engaging portion combinable with one hygiene piece. The hygiene piece includes a mutual engaging section mountable to the handle engaging portion in order to achieve an advantage of fast replacement. The hygiene piece includes a first rod, a plurality of holed sections formed on the first rod, and a plurality of detaching sections formed on the holed sections to provide an effect of assisting the operation and use of floss.

An oral care implement including a handle and a head. The oral care implement may be formed entirely out of a resilient or flexible material. The head may include a base structure and a monolithic cleaning unit. The monolithic cleaning unit may include a block portion extending from a front surface of the base structure and a plurality of protuberances extending from a distal end of the block portion. The block portion may have a greater height than the protuberances. The protuberances may include central protuberances that extend from a distal surface of the block portion and peripheral protuberances that surround the block portion and extend from the front surface of the base structure. The monolithic cleaning unit may include ribs extending between adjacently positioned protuberances. The oral care implement may be suitable for babies.

An applicator device including at least one holding section, at least one working tip, and a neck section connecting the holding section and the working tip, the device also includes a base body formed at least partially from a first plastic component, the base body being at least partially overmolded by at least one second plastic component that is softer than the first plastic component. In the region of the working tip, the at least one second plastic component at least partially coats the base body, and the coating includes outwardly projecting, bristle-type cleaning elements.

The handle has a proximal end and a distal end. The handle has an intermediate extent between the handle and the distal end. The housing has a handle adjacent to the proximal end. The housing has a head adjacent to the distal end. The housing has a plurality of tufts of bristles extending at right angles from the head. A toothpaste cartridge is provided within the handle. The handle has an intermediate component operatively coupled to the cartridge below. The intermediate component is operatively coupled to the head above. The head has a plurality of holes adjacent to the tufts. The intermediate component has a plurality tubes. The tubes operatively couple the cartridge and the holes. At least one valve is provided between the cartridge and the holes. In this manner the backlog of toothpaste is abated.
