An attachable and detachable head section for a toothbrush is provided. A main advantage of this invention is to enable a user to keep the toothbrush handle but change only the bristle head. There is thus less material ending up in the landfills. The head section includes an attachment mechanism that is configured to be releasably attached to the tip portion of the toothbrush handle.

A removable brush head for a personal groom device, the removable brush head having a stationary portion, wherein the stationary portion is annular and includes a plurality of outwardly-extending brush bristles. The removable brush head also includes a movable portion positioned within the stationary portion, wherein the movable portion is configured to at least partially rotate relative to the stationary portion, and further wherein the movable portion includes a plurality of outwardly-extending brush bristles. Additionally, the removable brush head includes a locking collar, wherein the locking collar is slidably couplable to the stationary portion so as to axially retain the movable portion within the stationary portion while allowing the movable portion to at least partially rotate relative to the stationary portion.

An oral care implement (1000) that includes a handle (100) and an oral care refill head (200). The oral care refill head (200) is alterable between a first state in which it is separated from the handle (100) and a second state in which it is coupled to the handle (100) by inserting a stem (120) of the handle (100) inside of a cavity (221) of the oral care refill head (200). The oral care refill head (200) has at least one alignment groove (250, 260) that receives at least one alignment rib of the stem (120) of the handle (100). Furthermore, the stem (120) and the oral care refill head (200) include snap lock features that form a snap-fit interlock to secure the oral care refill head (200) to the handle (100).

A hair brush system includes a brush housing having a handle neck portion and a fluid reservoir for holding a viscous fluid therein. The fluid reservoir is disposed within the brush housing. The hair brush system includes a plunger plate for engaging in the fluid reservoir of a gel or other viscous fluid product. The plunger plate is disposed within the brush housing. Valve devices are dispersed in a brush head, wherein the valves are fluidly coupled to the reservoir upon movement of the plunger plate from a first position to a second position upon engagement of a user.

A disposable cleaning pad having a grout cleaning brush includes a bristle attachment for use with a disposable pad. The bristle attachment is molded into a rectangular base piece forming a stand-alone removable brush that can be removably attached to a disposable pad. A top rectangular piece of similar dimensions to the base is connected to the end portion of the base by way of a hinge. The ends opposite the hinge have mating clasps that allow for the brush assembly to be securely yet removably fastened to an existing cleaning pad which is then mounted in the normal manner to the cleaning system. The brush assembly enjoys a longer life than that expected from a disposable cleaning pad thus the brush assembly may be reused many times before it needs to be replaced.

A method for manufacturing a handle, a connector, and a head by injection molding at least a part of the handle having a distal end and a proximal end comprising a hollow portion opposite the distal end. At least a part of the connector having an outer lateral surface and a recess therein by injection molding with the recess forming a cavity within the connector. A spring-loaded ball-snap element is provided that with a ball and a spring configured to apply a radial force onto the ball. The spring-loaded ball-snap element is inserted into the cavity of the connector and the spring-loaded ball-snap element is fixed therein. At least a part of the head is injection molded. The connector is inserted into the hollow portion of the handle and the connector and fixed. The ball is extended slightly beyond the connector's outer lateral surface surrounding the ball.

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.

The present invention provides a toothbrush and a device for attaching and/or detaching a toothbrush head. The toothbrush comprises a handle comprising a grip portion and a head attaching portion connected to the grip portion, a head comprising a body and bristles mounted to a first side of the body, the body further having a second side opposite to the first side, wherein a first hole is formed in one of the head attaching portion and the second side of the body, and a corresponding protruding plug is formed on the other of the head attaching portion and the second side of the body, the head is removably attached to the head attaching portion by inserting the protruding plug into the first hole. According to the present invention, the handle can be reused to improve resource utilization and reduce the amount of waste to be treated, as well as to enable the attachment and/or detachment of the head to be labor-savingly, easily and efficiently conducted.

A hairbrush may include a head portion, a handle extending from the head portion, and a cushion selectively coupleable with the head portion. The cushion is configured to be selectively loaded with one or more bristle bars, and each bristle bar may contain one or more bristles extending therefrom. The cushion may include a plurality of bristle openings arranged in rows. Each row of bristle openings can be loaded with no bristle bars, one bristle bar, or two bristle bars. When a row of openings in the cushion is loaded with two bristle bars, the two bristle bars are interlocked with one another along their respective lengths.

A replaceable brush head includes an upper surface, an outer perimeter edge, and a plurality of tufts. The upper surface includes a plurality of bristle tufts. The lower surface includes an outwardly extending knock-out button. The outer perimeter edge includes at least one protrusion. The replaceable brush head may be installed in a toothbrush body that includes a head portion having a recess sized to fit the replaceable brush head with a knock-out opening for the knock-out button and at least one channel for coupling to the at least one protrusion. The replaceable brush head can be removed from the toothbrush assembly by applying a force to the knock-out button in the direction of the tuft plate.
