A plank finish applicator assembly for simultaneous application of finish to multiple planks includes a brush head to which a rod is attached. The brush head comprises a plurality of bristles having a plurality of recesses extending into its lower face and between its front and rear edges to define at least two sets of elongate bristles. At least one opposed edge of the plurality of bristles comprises a set of elongate bristles. The recesses and the sets of elongate bristles have widths substantially equivalent to those of a plank in a field of planks and a gap or a channel that is defined by adjacently positioned planks, respectively. The rod is used to dip the bristles into liquid finish and to motivate the brush head across the field to apply the liquid finish to upper and opposed side facets of the planks.

A device for lubricating a surface of a tubular element includes a shaft portion having a longitudinal axis, where the shaft portion is formed from plastic, and a brush portion located on the shaft portion. The brush portion has at least one contact zone for contacting a surface. The brush portion is formed from a brush portion material and a lubricant agent, which is transferred from the at least one contact zone to a surface during use.

A device for lubricating a surface of a tubular element includes a shaft portion having a longitudinal axis, and a brush portion located on the shaft portion. The brush portion comprises at least one radial projection having a helical form. The protrusion comprises at least one contact zone for contacting a surface. An outer diameter of the helical form formed by the at least one contact zone is tapered at both longitudinal ends of the brush portion such that the outer diameter of the helical form is reduced at the longitudinal ends of the brush portion. The brush portion is formed from a brush portion material and a lubricant agent which is transferred from the at least one contact zone to a surface during use.

An adjustable tool holder is configured for interchangeable use with a variety of tools provided with different connection elements. The connection elements include at least a first connection element configured for a first manner of connection with the tool holder and a second connection element configured for a second manner of connection with the tool holder. The tool holder includes a distally extending tool support operable to detachably support each of the tools. The tool support includes a first tool connector configured to releasably connect with the first connection element in the first manner of connection. The tool support includes a second tool connector configured to releasably connect with the second connection element in the second manner of connection.

A method for applying a composition to teeth and a dispenser for dispensing a composition. The method of the present invention is directed to the storage and dispensing of a composition. During storage and subsequent use the composition in the storage chamber must be maintained segregated from the applicator surface. This is accomplished by delivering the composition from the storage chamber through a delivery channel having a length and a cross-sectional diameter sufficient to preclude the migration of moisture and the enzyme catalase from the application surface to the storage chamber. The composition is applied to teeth by means of bristles, a sponge surface or fibrillated surface. This applicator can be used with both aqueous and non-aqueous compositions.

A brush (400) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (400) comprises a body (402) having a rotational axis (438). The body (402) comprises a first end (407), a second end (411), opposite the first end (407), and a channel (408), comprising an axial inlet (409) and an outlet (480). The axial inlet (409) is at the first end (407) of the body (402) and is coaxial with the rotational axis (438). The brush (400) also comprises bristles (420), extending from the body (402) so that the bristles (420) are not parallel to the rotational axis (438) of the body (402).

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

An applicator (102) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (101) is disclosed. The applicator (102) comprises a body (110) and a plunger (186). The plunger (186) comprises a gate (118), movable within an outlet portion (182) of a first channel (115) of the body (110) between, inclusively, an open position, allowing the glutinous substance (168) to flow from an inlet (116) of the first channel (115) to an outlet (117) of the first channel (115) and a closed position, preventing the glutinous substance (168) from flowing from the inlet (116) of the first channel (115) to the outlet (117) of the first channel (115). The applicator (102) further comprises an actuator (131), selectively operable to move the plunger (186) such that the gate (118) moves between, inclusively, the open position and the closed position.

The method of the present invention is directed to the storage and dispensing of a peroxide containing tooth whitening composition. During storage and subsequent use the composition in the storage chamber must be maintained segregated from the applicator surface. This is accomplished by delivering the peroxide containing tooth whitening composition from the storage chamber through a delivery channel having a length and a cross-sectional diameter sufficient to preclude the migration of moisture and the enzyme catalase from the application surface to the storage chamber. The composition is applied to teeth by means of bristles, a sponge surface or fibrillated surface. This applicator can be used with both aqueous and non-aqueous peroxide containing tooth whitening compositions.

Provided is a dropper which includes a flexible cap, a tube body, and a head component. The flexible cap may be hermetically connected to one end of the tube body, and the head component may be connected to the other end of the tube body. The tube body may be hollow tube body. The flexible cap can be deformed, and the interior thereof is a hollow structure. An internal hollow part of the tube body communicates with the internal hollow part of the flexible cap. The head component is provided with an interconnecting structure for fluid to pass through such that fluid is able to enter the tube body or flow out of the tube body via the interconnecting structure.
