1. Field of the Invention
The invention relates to a paint container assembly for a paint sprayer, and more particularly to a paint container assembly with a vent conduit capable of preventing a paint material from flowing out of the paint container assembly during operation of the paint sprayer.
2. Description of the Related Art
The conventional paint container assembly 10 is disadvantageous in that a problem of leakage through the vent hole 131 (see
Therefore, the object of the present invention is to provide a paint container assembly that can overcome the aforesaid drawback associated with the prior art.
According to the present invention, there is provided a paint container assembly for a paint sprayer. The paint container assembly comprises: a container body that defines an accommodating space therein and that has a top open end and a bottom outlet port, the accommodating space being adapted to receive a paint material therein, the top open end defining a top opening in fluid communication with the accommodating space and the bottom outlet port, the bottom outlet port being adapted to be connected to the paint sprayer; a cover that is detachably mounted to the top open end, that covers the top opening, and that has a peripheral end and a central recessed portion which is surrounded by the peripheral end, which defines a cylindrical recess, and which is formed with a bottom inlet port in fluid communication with the cylindrical recess and the accommodating space, the central recessed portion extending into the accommodating space; and a vent conduit having a cylindrical plug portion and an extension portion. The plug portion is rotatably inserted into the cylindrical recess, defines an inner space that is in fluid communication with the cylindrical recess, and has an upper end. The extension portion has a free open end, defines a fluid channel that is in fluid communication with the inner space, and extends outwardly from the upper end of the plug portion to the free open end. The free open end of the extension portion of the vent conduit is disposed adjacent to the peripheral end of the cover and distal from the central recessed portion of the cover so as to prevent the paint material in the accommodating space from flowing out of the accommodating space through the cylindrical recess, the inner space and the fluid channel when the paint container assembly is tilted.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
The container body 20 defines an accommodating space 21 therein, has a top open end 22 and a bottom outlet port 24, and is formed with an outer thread 23 adjacent to the top open end 22. The accommodating space 21 is adapted to receive a paint material 100 (see
The cover 30 is detachably mounted to the top open end 22 of the container body 20, covers the top opening 220, and has a peripheral end 301 and a central recessed portion 33 which is surrounded by the peripheral end 301, which defines a cylindrical recess 31, and which is formed with a bottom inlet port 32 in fluid communication with the cylindrical recess 31 and the accommodating space 21. The central recessed portion 33 extends into the accommodating space 21. The cover 30 is formed with an inner thread 303 that engages threadedly the outer thread 23.
The vent conduit 40 has a cylindrical plug portion 41 and an extension portion 42 extending from the plug portion 41. The plug portion 41 is rotatably and sealingly inserted into the cylindrical recess 31 so as to be rotatable together with the extension portion 42 relative to the cover 30 (see
A direction-indicating sign 43 is disposed on a top surface of the extension portion 42 and a top surface of the plug portion 41 of the vent conduit 40 for providing a notification to set the free open end 421 of the extension portion 42 to a position above the upper end 412 of the plug portion 41.
Referring to
Referring to
With the inclusion of the extension portion 42 in the vent conduit 40 of the paint container assembly 2 of the present invention, it is possible to overcome the aforesaid drawback associated with the prior art.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
