A replacement head for detachable coupling to an oral care implement body. The replacement head may include a head having at least one treatment element and a tubular sleeve extending from the head and defining a cavity having an axis that receives a stem of the oral care implement body. The tubular sleeve may have a proximal edge that defines an opening into the cavity. A slot in the tubular sleeve is configured to mate with a boss of the stem of the oral care implement body. The slot may include an entry slot section extending from the proximal edge of the tubular sleeve towards the head and a locking slot section extending from the entry slot section towards the head. The locking slot section may have a first lateral wall that is oblique to the cavity axis and a second lateral wall that is parallel to the cavity axis.

Oral care implement and replacement head thereof

An oral care implement body to which a replacement head can be detachably coupled. In one embodiment, the oral care implement body includes a gripping portion having a shoulder, a stem extending from the shoulder along a longitudinal axis, and a boss protruding from an outer surface of the stem. The boss may have a locking rib section having an undercut surface that is axially spaced from the shoulder and a positioning rib section extending from the locking rib section to the shoulder. The undercut surface may circumferentially protrude from a first side surface of the positioning rib section. The locking rib section may extend along a first rib axis and the positioning rib section may extend along a second rib axis, the first rib axis oriented obliquely to the second rib axis.

Oral care implement body and replacement head therefor

An oral care implement and a method of forming the same. In one aspect, the invention can be an oral care implement having a handle and a head. The head has a basin cavity formed therein which has an open top end. An aperture is formed into the basin cavity that forms a passageway to an outer surface of the head. An applicator is positioned within the basin cavity so that a portion of the applicator protrudes through the aperture. The oral care implement also includes a head plate with a plurality of tooth cleaning elements mounted thereon. The head plate is coupled to the head and encloses the open top end of the basin cavity.

Oral care implement

A dispenser that includes a resilient applicator that optimizes application of a subject fluid to a desired surface. In one embodiment, the invention is a dispenser comprising a housing having an internal reservoir containing the fluid. The resilient applicator is coupled to the housing and comprises a dispensing orifice. The resilient applicator comprises a working surface that is oriented at an oblique angle to a longitudinal axis of the housing.

Dispenser

An oral care system comprising a toothbrush and a dispenser is disclosed. In one embodiment, the dispenser comprises a housing having a longitudinal axis and an internal reservoir containing an oral care material; a drive component rotatably disposed within the housing and comprising a drive screw, the drive component being axially retained relative to the housing through mechanical interference; and an elevator coupled to the drive screw so that rotation of the drive component in a first rotational direction causes the elevator to axially advance along the drive screw in a first axial direction to dispense the oral care material from a dispensing orifice.

Oral care dispenser and oral care system implementing the same

A dispenser that includes a resilient applicator that optimizes application of a subject fluid to a desired surface. In one embodiment, the invention is a dispenser comprising a housing having an internal reservoir containing the fluid. The resilient applicator is coupled to the housing and comprises a dispensing orifice. The resilient applicator comprises a working surface that is oriented at an oblique angle to a longitudinal axis of the housing and is defined by a polygonal perimeter edge, the polygonal perimeter edge comprising a plurality of apex portions and a plurality of side portions, wherein one of the plurality of side portions forms a distal most-portion of the resilient applicator.

A replacement head for an oral care implement, such as a powered toothbrush, wherein the replacement head utilizes a specially designed structure for coupling the replacement head to an oral care implement body. In one embodiment, the invention can be a replacement head comprising: a head having a plurality of tooth cleaning elements mounted thereto; a tubular sleeve comprising a cavity for receiving a stem of the body, a proximal edge defining an opening into the cavity, and a distal end to which the head is coupled, the tubular sleeve comprising a locking tab for engaging an undercut surface of a locking section of a boss.

Replacement head for an oral care implement, and oral care implement and method of utilizing the same

An oral care implement and a method of forming the same. In one aspect, the invention can be an oral care implement having a handle and a head. The head has a basin cavity formed therein which includes a basin floor and a basin sidewall and which has an open top end. An aperture is formed into the basin floor or the basin sidewall. An applicator is positioned within the basin cavity so that a delivery portion of the applicator protrudes through the aperture. The oral care implement also includes a head plate with a plurality of tooth cleaning elements mounted thereon. The head plate is coupled to the head and encloses the open top end of the basin cavity.

A refill head (), and oral care implement incorporating the same, wherein the refill head () can be uncoupled from a stem () of a handle () by withdrawing the refill head () from the stem of a handle () along the longitudinal axis of the oral care implement, which results in locking members () on the refill head () disengaging from an engagement rib () on the stem (). The locking members () and engagement rib () may be aligned with or angled relative to the longitudinal axis of the oral care implement. A portion of the stem may be visible through a portion of the refill head to reinforce the proper connection between the refill head and the handle.

Oral care implement and refill head therefor

An oral care implement, such as a toothbrush, which includes a handle and a replacement head utilizing a specially designed structure for coupling the replacement head to the handle of the oral care implement. The replacement head comprises a head and a tubular sleeve comprising a cavity for receiving a handle. A protuberance protrudes radially inward from an inner surface of the tubular sleeve for engaging a boss of a stem on the handle to impede rotation of the tubular sleeve about the stem in a first angular direction. A locking tab protrudes radially inward from the inner surface of the tubular sleeve for engaging an undercut surface of the boss to prevent axial disengagement of the tubular sleeve from the stem. The locking tab is circumferentially spaced from the protuberance so that a first axial channel exists therebetween for receiving a section of the boss.

An oral care dispenser and oral care system incorporating the system that includes a resilient applicator that optimizes application of the subject fluid to the desired oral surfaces. In one embodiment, the invention is a dispenser comprising a housing having an internal reservoir containing the fluid. The resilient applicator is coupled to the housing and comprises a dispensing orifice. The resilient applicator comprises a working surface that is oriented at an oblique angle to a longitudinal axis of the housing and is defined by a polygonal perimeter edge, the polygonal perimeter edge comprising a plurality of apex portions and a plurality of side portions, wherein one of the plurality of side portions forms a distal most-portion of the resilient applicator.

Oral care system, kit and method

A refill head, and a powered toothbrush including the same, wherein the refill head comprises a head portion including a movable tuft block that is rotated via operable coupling to a primary drive shaft of the handle. The head portion of the refill head is also receives vibrations from an eccentric that is operated by the primary drive shaft.
