  • Patent number: 8408834
    Abstract: A paint applicator is provided with a handle formed with a paint-entry passage, a first housing half connected to the handle, a second housing half jointed to the first housing half and formed with a plurality of paint exit holes, a non-permeable resilient body disposed on the second housing half and formed with a plurality of apertures, a permeable foamed body, and a brush layer. The apertures are closed in normal conditions and will be opened under pressure. Paint is accumulated in a paint chamber between the first and second housing halves, and then will flow out only when the paint pressure is greater than a deformation threshold value of the non-permeable resilient body. Furthermore, since the apertures are very small and can be evenly and densely distributed over the resilient body, paint will be evenly permeated to the permeable foamed body and the brush layer.

  • Publication number: 20100104353
    Abstract: A paint applicator includes a hollow handle defining a paint-entry passage, and a housing connected to the handle and having a first wall, and a second wall cooperating with the first wall to define a paint chamber that communicates fluidly with the paint-entry passage. The second wall has a plurality of first paint exit holes communicating fluidly with the paint chamber. A non-permeable resilient body covers the second wall, and includes a plurality of second paint exit holes aligned respectively with the first paint exit holes. A permeable foamed body covers the non-permeable resilient body. A brush layer is attached to the permeable foamed body, and is composed of a plurality of bristles.

  • Publication number: 20080005858
    Abstract: A paint applicator includes an applying unit and a joining unit. The applying unit includes a flat casing, an applying plate covering the flat casing and cooperating with the flat casing to define a receiving space, and at least one roller mounted on the flat casing externally of and at one side of the receiving space. The applying plate has a plurality of paint outlet holes spaced apart from each other. The roller projects outward from the flat casing and is rotatable about a first axis transverse to the applying plate. The joining unit includes a joining member connected pivotally to the flat casing, and opposite to the applying plate and rotatable around a second axis parallel to the first axis. The joining member includes an output passage communicated fluidly with the receiving space of the applying unit and adapted to supply paint material to the receiving space.

  • Publication number: 20070243009
    Abstract: A paint applicator includes a handle, a paint applying member, a lever, a container, a pump, and first and second tubing sections. The pump includes a chamber mounted on the handle, and a pumping assembly slidably mounted inside the chamber and actuated by an actuating section of the lever. The first tubing section interconnects a connecting hole of the handle and the pump. The second tubing section interconnects the container and the chamber. The lever is operable to actuate the pump to pump paint from the container to the paint applying member through the second tubing section, the chamber, the first tubing section, and the handle.

  • Patent number: 7255509
    Abstract: A paint roller assembly includes a roller support having head and neck portions and a support tube defining an axis, a coupling unit, and a roller unit. The support tube has a free end, and a plurality of spaced-apart apertures in fluid communication with an axial hole in the roller support. The neck portion has a retaining part. An end cap is sleeved on the free end of the support tube. The roller unit includes a tubular sleeve that has first and second end portions coupled rotatably and respectively to the retaining part and the end cap, and a sponge body fixed around the tubular sleeve. The coupling unit is disposed between the retaining part and the first end portion of the tubular sleeve. A handle is connected to the head portion of the roller support.

  • Publication number: 20070075098
    Abstract: A paint supply device includes a container defining a paint-storing chamber therein, a piston-and-cylinder assembly, and a finger-holding unit connected to the container. The container has a top threaded portion, and a cap secured to the top threaded portion. The piston-and-cylinder assembly includes a cylinder extending into the paint-storing chamber, and a hollow piston rod extending into the cylinder for withdrawing paint from the container to a paint applicator and having a top end disposed above the cap. A connecting head is connected to the top end of the piston rod, and is adapted to be connected to the paint applicator. The finger-holding unit has a hook member defining at least one finger-receiving recess disposed between the connecting head and the cap.
