1. Field of the Invention
This invention relates to a paint-coating brush and its coating process, particularly to a paint-coating brush and a coating process that avoids the time-consuming work of masking non-coating areas.
2. Description of Related Art
Paint-coating is quite necessary for both internal and external appearances of constructions. Whether doing multicolor coatings or fashion coatings, operators have to mask off areas that are not to be painted, such as window frames and built in electronic outlets, with masking tapes before starting the painting process, so as to ensure that non-coating areas are not contaminated. However, such a process consumes much more time than that required by the coating work proper, and also wastes lots of masking tapes. Besides, the used masking tapes left after the coating work also produce large quantity of wastage.
Accordingly, a conventional paint-coating brush as shown in
Furthermore, the paint-coating brush as shown in
The present invention relates to a paint-coating brush consisting of a rectangular flat body plate, a handle installed on a center of an upper surface of the body plate, and a plurality of bristles bundled on a lower surface of the body plate, wherein a front end portion of the said plate is bended downward to form a sharp R-shaped muzzle section.
The procedures of using the paint-coating brush include: (A) dipping the plurality of bristles in paint; (B) using a front end (tip) portion of the body plate to contact a borderline of a target object and then coating towards a central part of the object being painted. However, the procedure of masking non-coating areas is not included.
Nevertheless, the brush (foam) shown in Reference Cited 1 adopts sponges, wherein the peripheral regions of the foam are sealed and a baffle is installed sideling. Thus even though coating work starts after a front end portion of the baffle contacts with a borderline between coating and non-coating areas, spots may be left near the borderline, which isn't a pretty sight.
The present invention discloses a solution to the above-mentioned problems after a thorough analysis. A paint-coating brush according to the present invention consists of a rectangular flat body plate, a handle mounted on a center of an upper surface of the body plate, and a plurality of bristles bundled in a lower surface of the body plate, wherein a front end portion of the body plate is bended downward to form a sharp R-shaped muzzle section. The procedures of using the paint-coating brush include: (A) dipping the plurality of bristles in paint; (B) using a sharp front end portion of the body plate to contact a borderline of the target object, and then coating towards a central part of a coating area. However, the procedures of masking non-coating areas are not included.
The paint-coating brush and the coating process in the present invention effectively reduce time and labor that are originally spent in masking off non-coating areas as well as the wastage of masking materials. In this regard, the product is said to be highly efficient and useful.
The following explains an embodiment of the present invention in detail in line with the drawings, in which
The present invention particularly relates to a paint-coating brush and its coating process that avoids the work of masking off non-coating areas, which is the most time-consuming in a coating operation. The first claim described in the invented product relates to a paint-coating brush consisting of a rectangular flat body plate 1, a handle 2 mounted on a center of an upper surface of the body plate 1, and a plurality of bristles 3 bundled in a lower surface of the body plate 1, wherein a front end portion la of the body plate 1 is bended downward to form a sharp R-shaped muzzle section.
The second claim described in the invented product relates to a coating process involving the use of a paint-coating brush with a rectangular flat body plate 1, wherein a handle 2 is installed on a center of an upper surface of the body plate 1 and a plurality of bristles 3 are bundled in a lower surface of the body plate 1. The features of the paint-coating brush lie in the design of bending a front end portion 1a of the body plate 1 to form a sharp R-shaped muzzle section. The procedures of using the paint-coating brush include dipping the plurality of bristles 3 in paint, using a front end portion (tip) la of the body plate 1 to contact a borderline of a target object, arid then coating towards a central part of a coating area. The procedures of masking non-coating areas are excluded.
The invented product, scilicet, is a paint-coating brush as shown in
After dipping the plurality of bristles 3 in paint, use a front end portion (tip) 1a of the body plate 1 to contact a borderline between coating and non-coating areas and then coat towards a central part of a coating area. The coating processes in the present invention do not include procedures of masking off non-coating areas. Therefore paint won't be attached in non-coating areas even without doing masking work. Operators can paint evenly from a borderline between coating and non-coating areas towards a center of a coating area. The masking procedures for non-coating areas are eliminated, and thus the present invention can help save time and labor spent on masking work as required by conventional paint-coating brushes and their coating processes.
