Abstract: A paintbrush includes a fork and a roller. The fork, which is a Y-shaped member and is made of plastic, has main stem and two branches. Each of the branches has a base section extended outwardly from the main stem, a distal section connected to the base section and a connector connected to the distal section. A roller has opposite ends engaged with the connectors for rotation. A normal direction is defined parallel to the main stem. The base sections of the branches has a width and a thickness respectively, wherein the thicknesses of the base sections are substantially perpendicular to the normal direction, and the widths thereof are perpendicular to the thickness, and the widths are greater than the thicknesses. The distal sections of the branches tilted inwards, such that the roller will not disengaged with the connectors while a normal force is exerted on the roller.

Abstract: A paint roller assembly for paining the corner area between two abutted wall surfaces includes a main paint roller, which has a roller frame, a handle fastened to the roller frame, and a roller cover pivotally mounted on the roller frame for soaking and retaining paint and rotatable on the roller frame over a wall surface to apply retained paint to the wall surface, and a supplementary paint applicator, which has a body connectable to the roller frame of the main paint roller and an applicator element fastened to the body and located at a lateral side of the roller cover for soaking paint for application.

Abstract: A paint brush comprises a handle, a connection seat, and an application head. The handle is provided at the fastening end thereof with a receiving portion and a retaining slot in communication with the receiving portion. The connection seat is provided with a retaining member and a connection member. The connection seat is detachably fastened at one end thereof with the receiving portion of the handle such that the retaining member of the connection seat is retained in the retaining slot of the handle. The application head is connected at one end thereof with the connection member of the connection seat.

Abstract: A paint roller consists of a handle, a shaft extending form one end of the handle, a fastening member fastened rotatably engaged on with the rotary shaft and composed of a first cover body and a second cover body, and a roller cover fitted over the fastening member such that one end of the roller cover is located and sealed off by a retaining portion of the first cover body, and that another end of the roller cover is located and sealed off by an elastic protuberance of the second cover body, and further that the roller cover is confined by the retaining portion and the elastic protuberance to prevent the roller cover from displacing along the direction of the longitudinal axis of the fastening member. The paint deposited in the fastening member is thus prevented from splashing at both ends of the roller cover at the time when the paint roller is at work.

Abstract: A roller-type liquid applicator comprises a transporting tube member, a supporting device, a roller, a sealing device, and a gripping device. The transporting tube member is provided with a receiving hole extending along the longitudinal direction thereof, a liquid admitting hole, a liquid reverse flow hole, and a plurality of through holes. The roller comprises a fastening tube and a roller pad attached to the outer surface of the fastening tube. The fastening tube is provided with an axial hole having a diameter greater than the outer diameter of the transporting tube member, and a plurality of through holes. The supporting device is intended to enable the fastening tube to fit over the transporting tube member. The sealing device is used to seal off both open ends of the axial hole of the fastening tube. The gripping device is fastened with the transporting tube member.
