A roller for applying paint or other liquid or semi-liquid substances to surfaces. The roller includes a tubular frame that extends in a cylindrical shape. This tubular frame has two ends: a first end tapers outward (away from the main body of the tubular frame) to an enclosed conical point or apex. A second end is open and adapted to permit access to the interior volume of the tubular frame by a shaft of a roller frame. The open second end of the tubular frame permits selective removal and insertion of the paint roller shaft into the tubular frame. Typically, the tubular frame is held in place on the shaft by friction. A cover wrap dimensioned to circumferentially envelop the tubular frame is also included in the assembly; this cover wrap has a liquid-absorbent outer surface adapted for temporarily retaining paint, stain, or other liquid or semi-liquid substances.

A retention assembly for a hollow tubular decorating roller comprising a fixed mount member that is securable in use to a roller frame. The fixed mount member includes a first primary support formation and a first retention formation that extends radially beyond the first primary support formation. The retention assembly also includes a separable mount member that is selectively couplable with the fixed mount member. The separable mount member includes a second primary support formation and a second retention formation that extends radially beyond the second primary support formation. The first and second primary support formations are received, in use, by a respective end of a hollow tubular decorating roller. The first and second retention formations cooperate with one another while the separable mount member is coupled with the fixed mount member to in use retain a hollow tubular decorating roller therebetween.

A bottle including a reservoir for a liquid or semi-fluid product and a dispensing head projecting from the reservoir along a main axis. The dispensing head includes a roll-on applicator including a ball holder in which a ball is caged and from which a cap of the ball emerges. The bottle includes a rotary stopper suitable for covering the roll-on applicator in a closed position of the bottle, and for being released from the roll-on applicator for distributing product in an open position of the bottle. The ball holder is mounted translatably along the main axis, the roll-on applicator including an elastic component inserted between an applicator body and the ball holder. The ball moves in translation jointly with the ball holder to take a retracted position when the roll-on applicator is covered by the rotary stopper and a deployed position when the rotary stopper is released from the roll-on applicator.

A paint roller, a collar for a paint roller sleeve, a paint roller kit, and a paint roller assembly are described. In accordance with one aspect of the present disclosure, there is provided a paint roller assembly, comprising a paint roller sleeve and a paint roller. The paint roller sleeve includes a tubular body defining a passage therethrough. The passage defines a first aperture at a first end of the tubular body and a second aperture at a second end of the tubular body. A first collar is received in the first aperture, and a second collar is received in the second aperture. The paint roller includes a spindle rod including a first end and a second end opposite to the first end. The paint roller also includes a first reel rotatably mounted on the spindle rod proximate to the first end of the spindle rod, and a second reel rotatably mounted on the spindle rod proximate to the second end of the spindle rod. The first reel includes an engagement portion at a first end thereof for releasably engaging the first collar.

In one aspect, methods of making a carbon coating are described herein. In some implementations, a method of making a carbon coating comprises applying a first adhesive material to a substrate surface to provide an adhesive surface; rolling a carbon source over the adhesive surface to provide a carbon layer on the adhesive surface; and rolling an adhesive roller over the carbon layer to remove some but not all of the carbon of the carbon layer to provide the carbon coating.

A thin highly-open fabric or sleeve is placed over a paint roller cover, allowing the flow of paint in and out of the roller cover and smoother paint films.

A bottle including a reservoir for a liquid or semi-fluid product and a dispensing head projecting from the reservoir along a main axis. The dispensing head includes a roll-on applicator including a ball holder in which a ball is caged and from which a cap of the ball emerges. The bottle includes a rotary stopper suitable for covering the roll-on applicator in a closed position of the bottle, and for being released from the roll-on applicator for distributing product in an open position of the bottle. The ball holder is mounted translatably along the main axis, the roll-on applicator including an elastic component inserted between an applicator body and the ball holder. The ball moves in translation jointly with the ball holder to take a retracted position when the roll-on applicator is covered by the rotary stopper and a deployed position when the rotary stopper is released from the roll-on applicator.

A paint roller assembly, comprising a frame assembly including a handle and a frame, where one end of the frame is attached to the handle and the other end includes a cross-member structure attached to the frame opposite and orthogonal to the handle end, a first paint roller cage rotatably mounted on a first branch of the cross-member section, and a second paint roller cage rotatably mounted on a second branch of the cross-member structure. Optionally, a first paint roller cover can be placed over the first paint roller cage, and a second paint roller cover can be placed over the second paint roller cage, wherein at least one of the first paint roller cage and second paint roller cage has an end covered in paint-absorbing material for applying paint into a corner between adjacent surfaces.

A paint roller cover for applying multi-color paint is described. The paint roller includes a foam having a surface groove, the foam has an average cell size of 0.3 to 5 mm. The groove have a depth of 1 to 15 millimeters. A method of characterizing the uniformity of paint applied to a surface is also described. Further, a method of uniformly applying multicolor paint is described.

A device for lacquer transfer is disclosed including a frame, a transfer roller with a circumferential lateral wall, and a nozzle for dispensing lacquer, wherein the nozzle is connected to the frame, wherein an outside contact surface of the lateral wall comprises several depressions, wherein the transfer roller is mounted rotatably about an axis of rotation at the frame, wherein the nozzle is arranged contactless to or in direct contact with the outside contact surface of the lateral wall for dispensing lacquer into respective depressions in the lateral wall while the transfer roller is rotated about the axis of rotation, and wherein the transfer roller is configured to roll with the outside contact surface on a work surface of a work piece for transferring the lacquer from the depressions to the work surface of the work piece.
