## Title
Coating device

## Abstract

A coating device provided for connection to a discharge pipe of a coating container, includes a guide base and a cover. The cover is pivoted to the connecting end of the guide base, so that the cover can cover the guide section of the guide base to close the coating device, and can also be pivoted with respect to the guide base to open the coating device, which makes it convenient for the user to take out the residue of coating material from the guide space, so that the coating device can be used repeatedly. Furthermore, the coating material is guided by the guide ribs and the cover ribs to flow evenly to each of the discharge holes, which ensures even distribution of the coating material from the coating device.

## Background
BACKGROUND
Cross Reference to Related Application
This application claims the benefit of priority to TW 104136423, filed on Nov. 5, 2015 with the Intellectual Property Office of the Republic of China, Taiwan, the entire specification of which is incorporated herein by reference.
Field of the Invention
The present invention relates to a coating device, and more particularly to a coating device which is provided for connection to a coating container and can be used repeatedly.
Related Prior Art
To apply the coating material evenly to a surface, the conventional method is to squeeze the coating onto the surface and then rub the coating with a scraper until the coating is level with the surface. However, the coating application process is very complication, and the coating squeezing process and the coating rubbing process cannot be carried out synchronously at one time. Therefore, a coating device was invented, as shown in FIG. 1, and comprises: a feeding pipe portion 80 which communicates with one end of a discharge head portion 90, and another end of the discharge head portion 90 is provided with a plurality of discharge apertures 91. The coating device is connected to a discharge end of a coating container.
The coating material is moved from the discharge end of the coating container through the feeding pipe portion 80 into the discharge head portion 90, and finally discharged out of the discharge apertures 91.
However, a large amount of coating material will be left in the discharge head portion 90 after use, and is difficult to clean. If the coating is in gel form, it will be cured in the discharge head portion 90, and as a result, the discharge head portion 90 can not be used again.
Besides, during coating application, the discharge apertures 91 close to the center of the discharge head portion 90 will discharge more coating than other discharge apertures 91 located at both ends thereof, so that the coating is applied in an uneven manner.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

DETAILED DESCRIPTION
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to FIGS. 2-7, a coating device in accordance with the preferred embodiment of the present invention is provided for connection to a discharge pipe M of a coating container, and comprises: a guide base 10 and a cover 20.
The guide base 10 includes a neck section 11, and a guide section 12 with a first end connected to the neck section 11. The neck section 11 is a conical structure with an inner hole for insertion of the discharge pipe M. A second end of the guide section 12 is a connecting end 121, and the diameter of the guide section 12 gradually increases from the first end toward the connecting end 121. The guide section 12 includes a guide recess 122 which includes a guide surface 123 which is provided with a plurality of guide ribs D1. Two stop walls 124 are disposed at two opposite sides of the guide recess 122, and each include a hook portion J1 and at least one engaging protrusion K1.
The cover 20 includes a discharge end 21 to be pivoted to the connecting end 121 of the guide base 10. The cover 20 can cover the guide section 12 of the guide base 10 to close the coating device, and can also be pivoted with respect to the guide base 10 to open the coating device. The discharge end 21 is provided with a plurality of discharge holes 22 which are equidistantly spaced apart. The cover 20 further includes a cover recess 23, a cover surface 24 formed in the cover recess 23, and a restricting surface 25 opposite the cover surface 24. When the coating device is closed, the cover surface 24 is located toward the guide surface 123. The cover surface 24 includes a plurality of cover ribs D2 which are located in alignment with the guide ribs D1. When the coating device is closed, a guide space R which communicates with the discharge holes 22 will be formed between the guide recess 122 and the cover recess 23. The cover 20 is provided at two sides with at least one hook portion J2, and at least one retaining portion K2, and the hook portions J2 are located at two sides of the cover surface 24, as shown in FIG. 6. When the coating device is closed, the engaging protrusions K1 are engaged with the retaining portions K2, so as to fix the cover 20 to the guide base 10. Meanwhile, the hook portions J1 are hooked to the hook portions J2 to prevent leakage of coating material. As shown in FIG. 4, the restricting surface 25 of the cover 20 is provided with at least one stop portion 26 which is located at the discharge end 21. In this embodiment, there are two stop portions 26 which are located at two sides of the discharge end 21 to restrict the pivot angle of the cover 20, which prevents excessive rotation angle of the cover 20, consequently preventing the connection between the cover 20 and the guide base 10 from breaking up. Preferably, the cover 20 is formed to fit the shape of the guide section 12 of the guide base 10. An opposite end of the cover 20 to the discharge end 21 is a feeding end 27 which is narrower than the discharge end 21. The cover 20 further includes a discharge section 211 connected to the discharge end 21, and a feeding section 271 connected to the feeding end 27. There are four retaining portions K2, which are arranged at two sides of the discharge section 211 and the feeding section 271. When the coating device is closed, the retaining portions K2 are aligned to the engaging protrusions K1.
When in use and the coating device is closed, a user presses the coating container to make the coating material flow through the discharge pipe M to the guide space R, and then the coating material is guided by the guide ribs D1 and the cover ribs D2 to flow evenly to each of the discharge holes 22, so that the coating material can be discharged in an even manner. After use, the just needs to release the hook portions J1 from the hook portions J2, and rotates the cover 20 with respect to the guide base 10 to open the coating device, so that the user can remove the residue of coating material from the guide space R. After removal of the residue of coating material, the user can rotate the cover 20 in a reverse direction until the hook portions J1, J2 are hooked together, so that the coating device is closed and can be used repeatedly.
It can be learned from the above description that the cover 20 is pivoted to the connecting end 121 of the guide base 10, so that the cover 20 can cover the guide section 12 of the guide base 10 to close the coating device, and can also be pivoted with respect to the guide base 10 to open the coating device, which makes it convenient for the user to take out the residue of coating material from the guide space R, so that the coating device can be used repeatedly.
Furthermore, the coating material is guided by the guide ribs D1 and the cover ribs D2 to flow evenly to each of the discharge holes 22, which ensures even distribution of the coating material from the coating device.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
