Title: fluid dispensing nozzle structure

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention generally relates to an improved fluid dispensing nozzle structure. More particularly, the invention relates to an improved fluid dispensing nozzle structure that can substantially reduce the flow and the flowing speed to avoid splashing during operation. 
     2. Description of the Prior Art 
     As of now, fluid dispensing spouts  1  have been widely used for liquid soup bottles and bottles holding other types of fluids (for example, condiments). These fluid dispensing spouts  1  are easy to use. A user only has to lightly press the top portion of the spout to dispense the content. 
     Though they are easy to use, they have a big drawback. If the content is thick or viscous enough, the content would come out slowly when the spout is pressed. However, if the content is not thick or viscous enough, the content would rush out swiftly and cause splash (as illustrated in  FIG. 1 ). 
     From the above, we can see that the fluid dispensing spout of the prior art has at least a major disadvantage and needs to be improved. 
     To eliminate the disadvantage of the fluid dispensing spout of the prior art, the inventor has put a lot of effort into the subject and has successfully come up with the improved fluid dispensing nozzle structure of the present invention. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide an improved fluid dispensing nozzle structure that can substantially reduce the flow and the flowing speed to avoid splash. 
     Another object of the present invention is to provide an improved fluid dispensing nozzle structure that is structurally simple, easy to use and easy to be disassembled. 
     To reach these objects, the improved fluid dispensing nozzle structure of the present invention is disclosed. The improved fluid dispensing nozzle structure of the present invention comprises a spout portion, an L-shape tubular portion and an Anti-Splashing Cap. A retaining portion is disposed at the front end of the spout portion and is in fluid communication with a path located in the spout portion. A first (connective) opening is disposed on the proximal end of the L-shape tubular portion, and a second opening is disposed on the distal end of the L-shape tubular portion. The L-shape tubular portion is connected with the spout portion through the engagement between the first (connective) opening and the retaining portion. A threaded external surface is disposed on the outside of the second opening. A first flow reducing protrusion is disposed on the bending portion of the path. A threaded internal wall is disposed on the inside of the Anti-Splashing Cap. A second flow reducing protrusion is centrally disposed in the Anti-Splashing Cap. At least one outlet is disposed by the second flow reducing protrusion. The fluid may come out through the outlet. The two protrusions and can substantially reduce the flow and the flowing speed of the content; therefore, splash may be avoided. 
     These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying Drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Please refer to  FIGS. 2 and 3 , which illustrate the improved fluid dispensing nozzle structure of the present invention. The improved fluid dispensing nozzle structure of the present invention comprises a spout portion  2 , an L-shape tubular portion  3  and an Anti-Splashing Cap  4 . A retaining portion  21  is disposed at the front end of the spout portion  2  and is in fluid communication with a path  22  located in the spout portion  2 . A first (connective) opening  31  is disposed on the proximal end of the L-shape tubular portion  3 , and a second opening  32  is disposed on the distal end of the L-shape tubular portion  3 . A threaded external surface  33  is disposed on the outside of the second opening  32 . The first (connective) opening  31  and second opening  32  are in fluid communication with a path  34  located in the L-shape tubular portion  3 . A first flow reducing protrusion  35  is disposed on the bending portion of the path  34 . The L-shape tubular portion  3  may be connected with the spout portion  2  through the engagement between the first opening  31  and the retaining portion  21 . A threaded internal wall  41  is disposed on the inside of the Anti-Splashing Cap  4 . A second flow reducing protrusion  42  is centrally disposed in the Anti-Splashing Cap  4 . At least one outlet  43  is disposed by the second flow reducing protrusion  42 . The fluid may come out through the outlet  43 . The Anti-Splashing Cap  4  may be fixedly connected with the L-shape tubular portion  3  through the engagement between the threaded internal wall  41  and the threaded external surface  33 . 
     Now, please refer to  FIG. 4 , which is a sectional view illustrating the improved fluid dispensing nozzle structure of the present invention in use. When a user presses the spout portion  2 , the fluid would flow through the path  22  and the path  34 . Now, the first flow reducing protrusion  35  and second flow reducing protrusion  42  guide and reduce the flow so that the fluid may come out from the outlet  43  of the Anti-Splashing Cap  4 . The two protrusions  35  and  42  can substantially reduce the flow and the flowing speed; therefore, splash may be avoided. 
     Because the unit  4  is fixedly connected with the L-shape tubular portion  3  through the engagement between the threaded internal wall  41  and the threaded external surface  33 , we can separate the unit  4  from the L-shape tubular portion  3  easily if we want to clean up the unit  4 . 
     In another embodiment of the present invention, the spout portion  2  may be made into an integral part of the L-shape tubular portion  3 . Please see  FIG. 5 . 
     In comparison to the prior art, the improved fluid dispensing nozzle structure of the present invention has the following advantages: 
     1. The improved fluid dispensing nozzle structure of the present invention can substantially reduce the flow and the flowing speed of the content; therefore, splash may be avoided. 
     2. The improved fluid dispensing nozzle structure of the present invention is structurally simple, easy to use and easy to be disassembled. 
     Many changes and modifications in the above described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
