Abstract

A nozzle and the method for manufacturing thereof are disclosed. The manufacturing method includes the following steps: 1. forming a base with a closure and a supporting frame with two corresponding shafts on the top thereof via extruded hard plastic; 2. inserting a central mold into the supporting frame such that the shafts on the top of the supporting frame may be slightly outward; 3. secondly applying extruded plastic on the top of the supporting frame to form a mouthpiece; and 4. thirdly applying extruded plastic on the bottom of the supporting frame to accomplish a nozzle with excellent touch feeling and firm structure. By way of the above steps, the nozzle according to the present invention presents a soft touch feeling and would not easily fall off of the conduit of the water bag due to the sucking of the user.
